Community health education: future skills or a dead-end?

The introduction of Community PREP was welcomed as a chance for OHNs to become part of the community health team. However, recent plans for primary health have excluded OH nursing, and the disappearance of diploma level education has raised concerns that OHNs are not being provided with the core skills required by employers. HELEN KOGAN asks if OHNs are not to be included within the primary healthcare team, where do they fit? And if not, are the right skills for employment being provided by degree-level education?

Arousal and stress response across the menstrual cycle in women with three perimenstrual symptom patterns.

The purpose of this study was to compare arousal levels and stress response across menstrual cycle phases in women with three perimenstrual symptom patterns. Women with low symptom severity (LS, N = 28), were compared with those with a premenstrual syndrome (PMS, N = 15) and premenstrual magnification (PMM, N = 19) pattern across postmenses and premenses phases. Each woman was assessed during relaxation and in response to mental task and symptom imaging stressors during a postmenses and premenses day. Results of baseline skin conductance (SCL), electromyogram (EMG), and finger temperature (T) demonstrated arousal premenses in women with the PMS pattern, but not in women with the LS pattern. In addition, women with the PMS pattern experienced increased EMG and SCL response to stressors premenses. Women with the PMM pattern experienced a rise in finger temperature premenses, opposite the pattern of the women with LS or PMS. These results support development of symptom management strategies to reduce arousal and modulate stress response for women with PMS who seek help for their symptoms. In addition, the difference in arousal and stress response observed in women with PMS and PMM support development of different symptom management strategies for these two groups of women.

Hayfever: a modern condition.

While the majority of the population celebrates the summer outdoors, spare a thought for those who begin to suffer as soon as the pollen count begins to rise. Helen Kogan looks at the rising incidence of seasonal allergic conjuctivo-rhinitis and describes the help that can be offered to employees during this period.

Flu vaccinations: are they worth the cost?

Flu immunisation programmes have been offered by many organisations this year and companies will be expecting to see the dividend of reduced absenteeism. But are nonselective vaccinations worth the expense? Helen Kogan weighs up the arguments.

Passive smoking: only a question of time.

It is believed to be just a question of time before an employee successfully sues a company for the damaging effects of environmental tobacco smoke (ETS). With No Smoking Day on March 10 Helen Kogan looks at current developments in research and new health and safety law that add weight to the calls for more stringent guidance on workplace smoking.

Substance abuse. Taking the lead in workplace policies.

The number of companies with alcohol policies is rapidly increasing. This trend has been largely led by health and safety departments in safety-sensitive industries. Helen Kogan believes that the time is now right for OH professionals to re-examine their involvement and take the lead in introducing preventive health care strategies in the workplace.

Managing migraine.

Absenteeism by migraine sufferers is treated with little sympathy by employers and fellow workers even though it is a condition that affects nearly eight per cent of the population. Helen Kogan looks at how an understanding of its debilitating effects can reduce the stigmatisation of employees.

Power spectral analysis of heart rate variability after biofeedback training.

This study investigated the effects of biofeedback/self-management training on heart rate variability (HRV) in six sudden cardiac arrest survivors. The physiological-theoretical basis of the training was cognitively inducing respiratory sinus arrhythmia. Power spectral analyses and nonspectral analyses (Kleiger, Magid, SCANN, BB50 measures) of HRV measured before and after 5 weeks of biofeedback training are described. The posttraining Kleiger measure of mean HRV increased compared to the pretraining mean HRV (159 +/- 37 ms vs 147 +/- 38 ms). After training, the high frequency components (0.27-0.30 Hz) of the power density spectra were markedly increased, suggesting an increase of respiratory-driven parasympathetic activity. After training, the low frequency components (0.05 Hz) were slightly decreased, suggesting a decrease in sympathetic activity. The increases noted in the high frequency components were more striking during 9 hours at night than during the day. These data indicate that subjects who have had sudden cardiac arrest can, through biofeedback/self-management, cognitively increase their HRV over a 5-week period, consequently increasing parasympathetic activity.

Postural hypotension in chronically medicated schizophrenics.

Blood pressure readings at rest and on standing in 196 chronic schizophrenic patients on stable long-term antipsychotic treatment were compared with those in unmedicated healthy controls. Patients recorded significantly lower resting blood pressure and significantly higher prevalence of postural hypotension than controls. The prevalence of postural hypotension in patients was 77% at 1 minute and 16.8% at 3 minutes after standing compared with absence of postural hypotension in controls at both time points. Prevalence of postural hypotension was unaffected by age or sex and was poorly correlated with drug dose, except in young patients. alpha 1-Receptor binding affinity of antipsychotic drugs was not predictive of postural hypotension. The possible significance of such persistent postural hypotension in chronically medicated patients is discussed.

Measurement of recovery from myocardial infarction using heart rate variability and psychological outcomes.

This pilot study was designed to describe heart rate variability (HRV), anxiety, anger, denial, and depression during the first 4 days and 6 months after acute myocardial infarction (AMI). The sample was composed of 21 post-AMI males aged 40 to 83. State anxiety was elevated early. At 6 months it had significantly decreased. The nonpower measure of HRV, the Kleiger global standard deviation, was decreased to a mean score of 86 (SD = 29) msec during AMI and was 117 (SD = 30) msec at 6 months. Although there were no significant correlations between HRV, psychological response, age, and education, there were moderate correlations between HRV and state anger (r = .33), denial (r = .35), and education (r = .45). HRV, as measured by the power spectral density function of an autoregressive model, demonstrated an increased peak across the band of frequency associated with the high-frequency components of the parasympathetic system and a decreased peak across the band associated with the low-frequency components of the sympathetic system at 6 months as compared to the AMI period.
