Farming and mental health problems and mental illness

BACKGROUND

Farmers experience one of the highest rates of suicide of any industry and there is growing evidence that those involved in farming are at higher risk of developing mental health problems. This article provides an overview of the literature examining mental health issues experienced by farming populations in the United Kingdom, Europe, Australia, Canada and the United States and identifies areas for further research.

METHOD

A literature review (Medline, Science Direct, Ingenta, Proquest and PsychINFO) was carried out using the words 'farmers', 'agriculture', 'depression', 'mental health', 'mental illness', 'stress', and 'suicide', as well as a review of relevant papers and publications known to the authors. (Papers not written in English and those published prior to 1985 were excluded.)

RESULTS

Fifty-two papers were identified with the majority focusing on stress and coping styles in farmers (24). A number of studies also focused on neuropsychological functioning and agricultural chemical use (7), depression (7), suicide (9), general mental health (4) and injury and mental health (1). This body of research studied male farmers, female farmers, farm workers, farming families, and young people living on farms. Research to date indicates that farmers, farm workers and their respective families face an array of stressors related to the physical environment, structure of farming families and the economic difficulties and uncertainties associated with farming which may be detrimental to their mental health.

CONCLUSION

Whilst suicide rates in some groups of farmers are higher than the general population, conclusive data do not exist to indicate whether farmers and farming families experience higher rates of mental health problems compared with the non-farming community. It is clear, however, that farming is associated with a unique set of characteristics that is potentially hazardous to mental health and requires further research.

Gleason Scoring Varies Among Pathologists and this Affects Clinical Risk in Patients with Prostate Cancer

AIMS

To investigate whether our practice of specialist review of all diagnostic biopsies was necessary to prevent misgrading of referred prostate cancer patients, and whether this misclassification, if any, would have resulted in misclassification of clinical risk grouping (Seattle Risk Grouping [SRG]) and subsequent treatment strategy and prognosis.

MATERIALS AND METHODS

Important prognostic indicators for prostate cancer include the presenting prostate-specific antigen (PSA), clinical stage and Gleason sum of the tumour. These three variables are incorporated into the SRG cohorts to establish treatment strategy. Patients with prostate cancer referred for brachytherapy had their prostate biopsies reviewed by a reference pathologist (PD) with a special interest in prostate cancer. We compared the agreement between the scoring of the referring pathologists with that of PD, and evaluated if any differences changed the SRG and therefore the clinical risk and treatment strategy for the patients.

RESULTS

In only 52% (43/83) of cases, was there total agreement between the two sets of pathologists. The inter-rater agreement was statistically 'fair' (unweighted kappa statistic 0.27). In 90% (36/40) of cases with disagreement, PD assigned higher Gleason sums. In 40% (16/40) of cases with disagreement, the change in Gleason sum altered the SRG; in one out of 16 cases, the SRG was downgraded from 'intermediate' to 'low' risk disease; in six out of 16 cases, it was upgraded from 'low' to 'intermediate' risk, and, in nine out of 16, from 'intermediate' to 'high' risk.

CONCLUSION

Our findings confirm previous reports of only limited correlation between pathologists in reporting Gleason sums. In this study, 19% (16/83) of cases had their grading changed to a level that altered clinical risk, almost always (94%; 15/16) to one that worsened prognosis. This would have significantly affected treatment strategy for these patients, and thus we recommend that all centres ensure accurate Gleason grading by the use of pathologists with special interests in prostate cancer.

European Collaborative Group on Prostate Brachytherapy: Preliminary Report in 1175 Patients

OBJECTIVE

To establish a multi-centre database of a large number of patients treated with brachytherapy across Europe.

METHODS

A total of 1175 patient files were registered in the database and the completeness of the data on these patients resulted in the majority being included in the analysis.

RESULTS

The database of patients treated with brachytherapy across Europe indicates that optimal patient selection for this procedure has been made, both in terms of outcome and side-effects, which will be subject of future analyses. This should enable refinement of the treatment choice and administration as well as provide useful guidance to other centres that want to establish this procedure for their patients. It will also set the ground for prospective studies.

CONCLUSIONS

The established database indicates that brachytherapy as a treatment option for prostate cancer is well established in many centres.

Anxieties and attitudes towards abortion in women presenting for medical and surgical abortions

OBJECTIVE

To examine the differences in anxiety levels and attitudes towards abortion between women having an early medical abortion and women having a surgical (manual vacuum aspiration) abortion.

METHODS

Women who presented for an early medical abortion or a surgical abortion at an urban, free-standing abortion clinic were invited to participate in this study. Fifty-nine women having a medical abortion and 43 women having a surgical abortion answered questionnaires before their scheduled abortion, and again 2 to 4 weeks after the abortion. Thirty women were interviewed about their answers.

RESULTS

Anxiety levels were similar in both groups before the abortion procedure. Anti-choice views about abortion were seen in 60.5% of women having a medical abortion and in 37.3% of women having a surgical abortion (P = .027). Women who were pro-choice had a mean anxiety score of 5.0 (range, 0-10) before and 2.7 after the abortion, whereas women who were anti-choice had a mean anxiety score of 5.2 before and 4.4 after the abortion (P = .005).

CONCLUSION

It is important for providers of abortion care to understand that women undergoing a medical abortion may be more ambivalent about abortion than women undergoing a surgical abortion, and women who are anti-choice but having an abortion may have unresolved anxiety after the procedure.

MAP kinase activation in cells exposed to a 60 Hz electromagnetic field

This research provides evidence that mitogen-activated protein kinase or extracellular signal-regulated kinase (MAPK/ERK) is activated in HL-60 human leukemia cells, MCF-7 human breast cancer cells, and rat fibroblast 3Y1 cells exposed to a 60 Hertz (Hz), 1 Gauss (G) electromagnetic field (EMF). The effects of EMF exposure were compared to those observed using 12-O-tetradecanoylphorbal-13-acetate (TPA) treatment. The level of MAPK activation in cells exposed to EMF was approximately equivalent to that in cells treated with 0.1-0.5 ng/ml of TPA. A role for protein kinase C (PKC) in the process leading to MAPK activation in EMF exposed cells is also suggested by the results. MAPK activation is negated by an inhibitor to PKCalpha, but not PKCdelta inhibitors, in cells subjected to EMF exposure or TPA treatment. Thus, similarities between the effects of EMF exposure and TPA treatment are supported by this investigation. This provides a possible method for revealing other participants in EMF-cell interaction, since the TPA induction pathway is well documented.

Outcome analysis and patient satisfaction following octant transrectal ultrasound-guided prostate biopsy: a prospective study comparing consultant urologist, specialist registrar and nurse practitioner in urology

PURPOSE

To determine whether transrectal ultrasound-guided biopsy of the prostate is equally reliable and acceptable if performed by urology nurse practitioner or urologist.

SCOPE

Octant biopsies were taken by each operator (consultant urologist n=2, urology specialist registrar n=1 and urology nurse practitioner n=2) from 50 consecutive unselected patients and demographics and cancer detection rate were compared between the groups. A postal survey was performed following nurse practitioner biopsy to assess patient satisfaction and acceptance of nurse practitioner biopsy.

CONCLUSION

Transrectal ultrasound-biopsy of prostate whether performed by nurse practitioner or urologist is equally reliable if adequate training is provided. Patients are happy to undergo prostate biopsy and receive information about the diagnosis from an appropriately trained prostate cancer nurse specialist.

Toxicity and Early Biochemical Outcomes From 125Iodine Prostate Brachytherapy in the U.K

AIMS

Transperineal interstitial prostate brachytherapy is increasingly available to patients with early prostate cancer in the U.K., but limited data are available about the toxicity and early results in the U.K. prostate cancer population. We describe our experience and results from prostate brachytherapy to date.

MATERIALS AND METHODS

Two hundred and fifty-five patients were treated at St Luke's Cancer Centre, Guildford, U.K., between March 1999 and November 2002. Of these, over 3 months of follow-up data were available for 216 patients. Patients were assessed at 6 weeks and then at 3, 6, 9 and 12 months after implant, and at 6 monthly intervals thereafter. Prostate-specific antigen (PSA), International Prostate Symptom Score (IPSS) and toxicity, including catheter use, was recorded prospectively.

RESULTS

Median PSA at 1, 2 and 3 years was 0.5, 0.4 and 0.1 ng/ml, respectively. Ninety-five per cent of patients experienced temporary deterioration in their urinary symptoms, which persisted at clinically significant levels (IPSS increase >3 points) for 9 months after implant. The severity of urinary symptoms (IPSS) after implant was most closely related to IPSS at presentation (P<0.001). Acute urinary retention (AUR) occurred in 20 (9.3%) patients, with a further 26 (12.1%) patients using clean intermittent self-catheterisation (CISC) to reduce voiding frequency associated with chronic retention. Median duration of catheter use was 4 weeks. Multivariate analysis revealed that urodynamic status, prostate volume and IPSS score were independently significant (P<0.05) predictors of post-implant catheter use. Twelve patients (5.6%) reported either rectal urgency or mild, self-limiting rectal bleeding.

CONCLUSION

Brachytherapy was tolerated well, with self-limiting urinary, bowel and sexual toxicity in most patients. Postoperative catheter use in our population is closely linked to pre-implant IPSS score, baseline prostate volume and urodynamic obstruction status. This work confirms the prognostic value of urodynamic assessment, which adds useful prognostic information to assessment of known risk factors such as prostate volume and IPSS.

Is Bicalutamide Equivalent to Goserelin for Prostate Volume Reduction before Radiation Therapy? A Prospective, Observational Study

INTRODUCTION

We compare the cytoreductive efficacy of bicalutamide or goserelin with no hormonal manipulation in prostate cancer before brachytherapy.

MATERIALS AND METHODS

Transrectal ultrasound volume estimations were performed in clinic and during the brachytherapy-planning scan. Between volume estimations, patients received no hormonal treatment, bicalutamide 150 mg once daily or goserelin 3.6 mg every 28 days.

RESULTS

Patients receiving no hormonal manipulation had a volume increase of 8% compared with an 8% volume reduction in the bicalutamide group and a 26% reduction in the goserelin group. As initial prostate volume was not equivalent in the three groups, a subgroup analysis was performed on patients who received active treatment for more than 3 months who had initial prostate volume less than 55 cm3. In this subgroup, a mean fall in prostate volume of 7%, occurred in the bicalutamide group compared with 21% in the goserelin group. In both the original and subgroup analysis, the cytoreductive efficacy of goserelin was significantly greater than bicalutamide (P < 0.0001).

CONCLUSION

In the absence of data from randomised trials, comparing the efficacy of these agents, luteinising hormone-releasing hormone (LHRH) analogues remain the gold standard for cytoreduction before prostate brachytherapy. If the neoadjuvant efficacy of hormonal manipulation in external beam radiotherapy is dependent on prostate volume reduction, then LHRH analogues may also prove more effective in this neoadjuvant role.

Decision-making preferences towards surgical intervention in a Hong Kong Chinese population

BACKGROUND

Economic, social, ethical and legal concerns are motivating changes in western-type health practice to encourage individuals to participate in health-care decisions. Patient participation in health care is perceived to be beneficial because health care is negotiated with the patient so the selected regimen of care is more likely to be acceptable. Hong Kong, in accordance with contemporary trends in other industrialized countries, has adopted a Patient's Charter that outlines patient's rights regarding health treatment and choices. Studies indicate that not all patients wish to take part in decision making about treatment.

AIM

To explore the degree to which a Hong Kong Chinese population desired to participate in decision making about surgical intervention.

METHOD

96 participants, 49 surgical and medical patients and 47 students of nursing, participated. Participants were given three hypothetical scenarios: cardiac failure, where major surgery is suggested; cholecystitis, where routine surgery is suggested; and the presence of a benign skin lesion, where minor surgery is suggested. Participants were asked about the degree to which they desired to participate in the decision-making process. There were five choices, ranging from the doctor having full control, to various types of collaborative decision making, to the individual having full control.

RESULTS

When the medical condition is not severe, participants desired greater participation in the decision-making process. Younger participants desired greater collaboration with the doctor in decision making while older participants preferred the doctor to have the greater input with respect to decision making.

Total arterial revascularisation as a primary strategy for coronary artery bypass grafting

BACKGROUND

Bilateral internal thoracic arteries confer improved survival benefit after coronary artery bypass grafting (CABG). Despite increasing evidence, the use of arterial conduits has not been accepted as a primary practice in most of the centres in the UK for various reasons. A series of patients has been analysed to assess the feasibility of total arterial revascularisation as a primary strategy in patients requiring first time CABG.

METHODS

Altogether 245 patients undergoing first time CABG by one surgeon, from June 1999 to October 2000, were studied. Group 1 consisted of 165 patients undergoing total arterial revascularisation (using bilateral internal thoracic and radial arteries) and group 2 consisted of 80 patients undergoing conventional CABG (using one internal thoracic artery and supplemental veins). Thirty day mortality and early morbidity with particular reference to resternotomy for bleeding, cerebrovascular accidents, renal failure, and sternal dehiscence were the main outcome measures.

RESULTS

Patients in group 1 were younger (mean (SD) 60 (10) v 65 (9) years; p<0.001), had lower Parsonnet scores (mean (SD) 5 (5) v 11 (7); p<0.001), and better left ventricular function. Both groups received a similar number of grafts. The percentage of patients undergoing total arterial revascularisation rose from 44% in the first three months to over 75% in the three latter three month periods. Overall 30 day mortality was 1.3%, one patient (0.6%) in group 1 and two patients (2.5%) in group 2. There was a similar incidence of postoperative complications and length of median postoperative stay in both groups.

CONCLUSION

Total arterial revascularisation can be adopted as a primary strategy in most patients undergoing CABG with no increase in mortality or morbidity.

(125)Iodine prostate brachytherapy: outcome from the first 100 consecutive patients and selection strategies incorporating urodynamics

OBJECTIVE

To report the results from the first 100 consecutive patients treated with 125I transperineal interstitial prostate brachytherapy between March 1999 and June 2001, and to determine if the International Prostate Symptom Score (IPSS), prostate volume or urodynamic variables correlate with acute morbidity.

PATIENTS AND METHODS

Patients were assessed prospectively by uroflowmetry, the IPSS, a physical examination and transrectal ultrasonography. Of the 100 patients, 57 had a full urodynamic assessment, 61 presented with lower urinary tract symptoms (LUTS), 25 were screen-detected and 14 presented with other problems. The IPSS was recorded at 1, 6 and 12 weeks, and then at 3-monthly intervals after treatment; significant events, e.g. acute urinary retention (AUR) and rectal symptoms, were recorded prospectively; the mean follow-up was 16 months.

RESULTS

No patients were incontinent after treatment. There was a temporary deterioration in IPSS in 89% of patients. Peak symptoms occurred at 6 weeks and a statistically significant deterioration in IPSS persisted until 9 months, but continued to improve throughout the follow-up. AUR affected seven patients, with a further 20 using clean intermittent self-catheterization (CISC) for symptoms. In most patients the symptoms resolved spontaneously to the levels before treatment, with only two patients requiring surgery for bladder outlet obstruction. The IPSS before treatment did not predict urodynamic obstruction. Urodynamically unobstructed patients did not require catheterization. By 2 years after implantation the mean IPSS was better than before treatment. Five patients had mild, transient proctitis.

CONCLUSION

Selecting patients with a low prostate volume and IPSS is likely to optimize the outcome of brachytherapy. Urodynamic studies may be helpful in predicting the risk of AUR and symptoms requiring CISC. Despite many patients presenting with LUTS, acute morbidity was no worse than that reported in large American series of predominantly screening-detected cancers. Prostate brachytherapy is well tolerated and may be safely delivered to patients with prostate cancer in the UK.

Postpartum positioning and attachment education for increasing breastfeeding: a randomized trial

BACKGROUND

Although lactation experts suggest that a correct positioning and attachment technique reduces breastfeeding problems and enhances long-term breastfeeding, evidence from randomized trials is lacking. The objective of this study was to evaluate the effect of postpartum positioning and attachment education on breastfeeding outcomes in first-time mothers.

METHOD

A randomized trial was performed in a public hospital in Adelaide, South Australia, where 160 first-time mothers were randomly allocated to receive either structured one-to-one education (experimental group) or usual postpartum care (control group) within 24 hours of birth. The primary outcome was breastfeeding at 6 weeks and 3 and 6 months postpartum; other outcomes were nipple pain and trauma in hospital and at 6 weeks and 3 and 6 months, and satisfaction with breastfeeding.

RESULTS

No significant differences occurred in breastfeeding rates between the groups at each endpoint, although a trend in the direction of lower rates was seen at each endpoint in the experimental group. This group reported less nipple pain on days 2 (p = 0.004) and 3 (p = 0.04), but this was not sustained on follow-up. No differences were observed in nipple trauma in hospital or in self-reported nipple pain and/or trauma at the three endpoints. Experimental group women were less satisfied with breastfeeding at 3 and 6 months postpartum when using a one-item measure; however, a multiple-item measure showed no significant differences at the three endpoints.

CONCLUSIONS

The intervention did not increase breastfeeding duration at any assessment time or demonstrate any differences between the groups on secondary outcomes. The trend toward lower breastfeeding rates in the experimental group suggests a need for a larger trial to evaluate whether or nor postpartum positioning and attachment education may negatively affect breastfeeding.

The Relationship Between the Evaluation Tool of Children’s Handwriting and Teachers’ Perceptions of Handwriting Legibility

Objective. The purpose of this study was to investigate the relationship between the Evaluation Tool of Children’s Handwriting (ETCH) and teacher’s perception of hand-writing legibility.

Methods. The ETCH was administered to 45 first-grade students with illegible handwriting as reported by their teachers. The teachers completed a teacher’s questionnaire at the same time to indicate the children’s level of handwriting difficulties both in general and in specific tasks that resemble the test tasks of the ETCH.

Results. There was no significant relationship between the ETCH scores and the teacher questionnaire scores in either general legibility or task-specific legibility.

Conclusion. The ecological validity of the ETCH, in reference to the teachers’ perception of handwriting legibility, was not established. Further changes for scoring criteria may be warranted before the ETCH can be used with confidence that the scores obtained are meaningfully related to actual performance in the classroom as determined by teachers.
