Country of birth, socioeconomic position, and healthcare expenditure: a multilevel analysis of Malmö, Sweden.

STUDY OBJECTIVE: The principle of equity aims to guarantee allocation of healthcare resources on the basis of need. Therefore, people with a low income and persons living alone are expected to have higher healthcare expenditures. Besides these individual characteristics healthcare expenditure may be influenced by country of birth. This study therefore aimed to investigate the role of country of birth in explaining individual healthcare expenditure. DESIGN: Multilevel regression model based on individuals (first level) and their country of birth (second level). SETTING: The city of Malmö, Sweden. PARTICIPANTS: All the 52 419 men aged 40-80 years from 130 different countries of birth, who were living in Malmö, Sweden, during 1999. MAIN RESULTS: At the individual level, persons with a low income and persons living alone showed a higher healthcare expenditure, with regression coefficients (and 95% confidence intervals) being 0.358 (0.325 to 0.392) and 0.197 (0.165 to 0.230), respectively. Country of birth explained a considerable part (18% and 13%) of the individual differences in the probability of having a low income and living alone, respectively. However, this figure was only 3% for having some health expenditure, and barely 0.7% with regard to costs in the 74% of the population with some health expenditure. CONCLUSIONS: Malmö is a socioeconomically segregated city, in which the country of birth seems to play only a minor part in explaining individual differences in total healthcare expenditure. These differences seem instead to be determined by individual low income and living alone.

Executive functioning and compliance in HIV patients.

25 adult HIV patients were evaluated in a study of appointments, medication, and compliance with restrictions on sexual activity. The Executive Interview (EXIT) was useful in assessing these patients for cognitive difficulties; compliance with medication and countertransference issues were negatively correlated with EXIT scores.

Maternal anxiety and attitudes to universal neonatal hearing screening.

Neonatal hearing screening of all babies within the maternity unit is now feasible using transient evoked otoacoustic emission (TEOAE) recording. However, in many maternity units in the United Kingdom, the majority of babies are discharged within the first 48 hours. During the first two days of life, there is a higher proportion of babies in whom emissions cannot be recorded. A universal TEOAE hearing screen has been implemented in Whipps Cross Hospital. As 70% of the babies are discharged from the maternity unit before they are 48 hours old, a two stage screen was implemented, with failure at the initial TEOAE test being followed by a retest after 4-6 weeks. The maternal anxiety caused by this model was investigated in 288 mothers enrolled for the initial TEOAE test. Generally, anxiety was low and attitudes towards the screen were positive. Ninety-seven per cent of mothers considered the screen to be worthwhile at the initial test with 15% feeling it had caused some anxiety but less than 1% being very worried. The mothers who had some anxieties were not dissatisfied with the screen, and within this group there was no increase in the proportion of babies who had failed the initial test. At the retest, two of 57 mothers (3.5%) considered they were very worried, but there was no significant deterioration in attitude towards the screen. Spielberger's State-Trait Anxiety Inventory revealed no significant difference in the anxiety state of the retest group when compared with a control group whose babies had not received a neonatal hearing test. The results of the initial test and the retest did not influence the anxiety state of the mothers. Ways of minimizing anxiety caused to a minority of mothers whilst maintaining positive attitudes to the screen are discussed.

The views of parents of hearing impaired children on the need for neonatal hearing screening.

Much research is now being undertaken into the implementation of universal neonatal hearing screens, but consumer opinion about such screening has not been widely available. The opinions of the parents of 356 children and young adults, with varying degrees of permanent hearing impairment were sought for the current study. They were questioned about their satisfaction with the age at which the hearing impairment was confirmed to be present in their child. Of 208 responses, only 58 were reasonably satisfied with the age at which their child's impairment had been confirmed. They were also asked whether they would have wanted a neonatal hearing screen had it been available. The overwhelming majority (166) would have welcomed such a test. This opinion was shared by the parents, even when their child had a mild or unilateral impairment. Parental comments about the advantages and disadvantages of neonatal screening are discussed.

Idiopathic hemochromatosis and chromosomal damage.

Spontaneous and radiation-induced chromosome damage in cultured lymphocytes was examined in a pilot study of 11 patients with idiopathic hemochromatosis and matched controls. Increased frequencies of chromosome breaks were found in the patients, both spontaneously and after exposure to ionizing radiation, but the differences between patients and controls were not statistically significant (p greater than 0.05) when individual data were analyzed. When pooled (group) data for patients and controls were compared, significant increases in spontaneous and radiation-induced chromosome breaks were found among the patients. The results suggest that iron overload may lead to chromosome damage in idiopathic hemochromatosis.

Maternal role of women in clerical jobs in southern Brazil: stress and satisfaction.

The number of women in the work force in Brazil is increasing, and a pattern of early work participation and a later decline continues to be manifested. The maternal role is a central role for these women. We investigated the quality of the maternal role as perceived by women who hold clerical jobs in a southern Brazilian city. Qualitative and quantitative data were collected from a random sample of 60 women. Thirty-three of these women were mothers with one or more children. Maternal role likes, dislikes, and stresses were obtained through questionnaires. Coping strategies and resources to cope with the maternal role needs were also obtained. Analytical categories were developed for each of these variables and the analysis was completed through the use of a qualitative computer program.

Tolerance and efficacy of recombinant human interferon gamma in the treatment of refractory genital warts.

PURPOSE: The intralesional administration of recombinant interferon alpha has led to resolution of genital warts in 50 to 70 percent of cases. However, continuous warts do not respond to such treatment, and human papillomavirus (HPV) infection of other anatomic sites remains untreated, so infection may continue to be transmitted. Since interferons have shown promise as effective therapies for genital warts, we decided to investigate the tolerance and efficacy of recombinant human interferon gamma in the treatment of refractory genital warts. PATIENTS AND METHODS: Nineteen women and nine men with refractory genital warts were treated in an open-label, dose-response trial of intramuscular recombinant human interferon gamma. RESULTS: Complete responses were seen in two (7 percent) and partial responses were seen in 13 (46 percent). Of 12 women with concomitant cervical HPV infection, eight demonstrated resolution with therapy. Response rates were higher in those patients who had warts less than nine months (73 percent) prior to therapy and in women (63 percent). Responses were not associated with HPV type. Flu-like symptoms during treatment were frequent but well tolerated. Transient abnormal laboratory results were more frequent with daily administration than with three times weekly therapy. Eleven of 16 subjects treated with cryotherapy after treatment with interferon experienced long-term remissions. CONCLUSIONS: In ambulatory patients with refractory genital warts, recombinant human interferon gamma appears to be biologically active and to have few adverse effects. The high efficacy rate achieved in subjects treated with cryotherapy after treatment with interferon suggests that further studies of combination therapy with these modalities are warranted.

Gas exchange and haemodynamics during thoracotomy.

Cardiac index, systemic and pulmonary arterial pressures, carbon dioxide elimination and ventilation of each lung were studied during thoracotomy. Seventeen patients, placed in the full lateral position, were ventilated mechanically through a Carlens' tube to moderate hypocapnia. Mean cardiac index increased by 12% as the pleura was opened (P less than 0.05), with no further change during surgery on the still ventilated upper lung. Mean arterial pressure was unchanged after opening the pleura, but decreased from 114 +/- 15 mm Hg (mean +/- 1 SD) to 104 +/- 18 mm Hg during surgery on the lung (P less than 0.01). Mean pulmonary artery pressure was unchanged. There was a significant (P less than 0.01) increase in carbon dioxide elimination from the upper lung when the pleura was opened. In addition, the ventilation of this lung increased significantly (P less than 0.05). Mean end-tidal PCO2 of the lower lung increased from 4.1 to 4.2 kPa after opening the pleura, while that of the upper lung increased from 3.0 to 3.6 kPa (P less than 0.01). VD/VT decreased from 43 to 38% as the pleura was opened (P less than 0.01). During surgical handling of the lung, marked decreases in ventilation, compliance, carbon dioxide elimination and end-tidal PCO2 were observed in the upper lung. We conclude that ventilation-perfusion mismatch decreased on opening the pleura, and that neither opening the pleura nor the subsequent lung surgery (both lungs being ventilated) caused any clinically important derangements in haemodynamics or oxygenation.

Carbon dioxide elimination from each lung during endobronchial anaesthesia. Effects of posture and pulmonary arterial pressure.

The ventilation and carbon dioxide elimination of each lung, and pulmonary arterial pressure, were studied in 17 patients during the early phases of anaesthesia for pulmonary surgery. The patients were ventilated mechanically to moderate hypocapnia. Expired tidal volume and carbon dioxide elimination rate of the lung to be operated on, and of the other lung, were similar in the supine position. There was a significant (P less than 0.01) increase in ventilation and a decrease in end-tidal PCO2 of the upper lung after turning the patient on to the side. Simultaneously, the physiological deadspace fraction of tidal volume (VD/VT) increased from 42 to 45% (P less than 0.05). Mean pulmonary arterial pressure (MPAP) increased slightly as surgery on the chest wall commenced. A concomitant increase of carbon dioxide elimination from the upper lung occurred also, although the distribution of ventilation, between the lungs, was unchanged in comparison with the conditions during undisturbed anaesthesia. Individual changes in MPAP (delta MPAP) and corresponding changes in VD/VT (delta (VD/VT)) were negatively correlated (r = -0.68, P less than 0.01). The regression equation was delta (VD/VT) (%) = 0.7 - 0.83 X delta MPAP (mmHg). It was concluded that variations in pulmonary arterial pressure during surgical stimulation may significantly affect the pattern of carbon dioxide elimination in the lungs. However, there was no evidence that these effects were important clinically.
