Intimate partner violence against women in rural Vietnam - different socio-demographic factors are associated with different forms of violence: Need for new intervention guidelines?

Background  

This population-based study investigated the different forms, magnitude and risk factors of men's violence against women in intimate relationships in a rural part of northern Vietnam and whether a difference in risk factors were at hand for the different forms of violence. Vietnam has undergone a rapid transition in the last 20 years, moving towards a more equal situation for men and women however, Confucian doctrine is still strong and little is known about men's violence against women within the Vietnamese family.     

Carboxyl-terminated poly(vinyl alcohol). Chain transfer of methyl propionate to vinyl acetate

Poly(vinyl acetate) was prepared at 60°C with benzoyl peroxide by using methyl[carbonyl-¹⁴C] propionate as chain transfer agent and solvent. The resulting polymer was hydrolysed to poly(vinyl alcohol) (PVAL) having carboxyl end groups and the average number of carboxyl groups per chain was unambiguously determined by comparing the activity of the polymer to that of the methyl propionate. An average density of 1,5 carboxyl groups per chain was found for poly(vinyl alcohol) prepared from poly(vinyl acetate) of DP 80 – 90. Other methods of end group analysis for carboxyl groups in PVAL are discussed.     

Girls prone to urinary infections followed into adulthood. Indices of renal disease

This study describes blood pressure and renal function, as well as indices of renal disease, in females with and without renal scarring followed from their first urinary tract infection (UTI) in childhood. Of the 111 patients with a median follow-up time of 15 years, 54 had renal scarring (reflux nephropathy) on urography, which was severe in 19 and moderate in 35. The glomerular filtration rate was lower in patients with severe renal scarring and correlated with renal area on urography. However, the filtration rate was decreased below the lower reference limit in only 7 patients, with a lowest value of 70 ml/min per 1.73 m². The diastolic blood pressure was higher in women with severe scarring. Hypertension of at least 140/90 mmHg was diagnosed in 3 of 54 (5.5%) females with renal scarring, 2 before and 1 at the follow-up examination. The excretion of albumin in urine was low and not correlated to filtration rate. Tubular enzymes in urine were similar in all groups. Thus the renal function was well preserved and the incidence of hypertension low. Within this range of renal function, the level of albumin in urine did not predict the degree of renal scarring.     

Association between low plasma levels of ophthalmic timolol and haemodynamics in glaucoma patients

Objectives The aims of the study were to assess the correlation between the plasma concentration of ophthalmic timolol and cardiovascular parameters, and the influence of timolol on advanced haemodynamic variables, such as stroke (SI), cardiac (CI) and systemic vascular resistance (SVRI) indices and arterial pulse wave velocity (PWV).Methods Twenty-five glaucoma or ocular hypertensive patients were treated with 0.5% aqueous and 0.1% hydrogel formulations of timolol using a randomised, double-masked, crossover, multicentre design. All the patients were subjected to passive head-up tilt, electrocardiography, exercise test and measurement of plasma concentration of timolol. In the analysis, the data on the two treatments were combined, and the Spearman correlation coefficients between the plasma level of timolol and physiological effects were calculated.Results During the head-up tilt test before rising the bed up, the resting heart rate (HR; R=–0.52, P=0.001) and PWV (R=–0.34, P=0.04) were inversely correlated with timolol level. In the upright position, ophthalmic timolol effectively suppressed the rise in HR (R=–0.36, P=0.03). The SI did not change with timolol concentration, while CI diminished as timolol concentration rose (R=–0.39, P=0.02). The SVRI correlated with timolol concentration (R=0.38, P=0.02). In the exercise test, correlation between HR and plasma level of timolol steadily grew stronger as the load increased, reaching R=–0.60 (P<0.0001) at the maximum load. Systolic and diastolic arterial pressures were not associated with the timolol concentration.Conclusion The plasma concentration of ophthalmic timolol correlates with several haemodynamic effects. As HR decreases, SVRI increases and blood pressure is kept unchanged.     

Transport of methylmercury and inorganic mercury to the fetus and breast-fed infant

It is well established that methylmercury (MeHg) and mercury vapor pass the placenta, but little is known about infant exposure via breast milk. We measured MeHg and inorganic mercury (I-Hg) in blood of Swedish mothers (n = 20) and their infants, as well as total mercury (T-Hg) in breast milk up to 13 weeks postpartum. Infant blood MeHg was highly associated with maternal blood MeHg at delivery, although more than twice as high. Infant MeHg decreased markedly until 13 weeks of age. Infant blood I-Hg was associated with, and about as high as, maternal blood I-Hg at delivery. Infant I-Hg decreased until 13 weeks. In breast milk, T-Hg decreased significantly from day 4 to 6 weeks after delivery but remained unchanged thereafter. At 13 weeks, T-Hg in breast milk was associated with infant MeHg but not with maternal MeHg. Conversely, T-Hg in breast milk was associated with maternal I-Hg but not with infant I-Hg. From the findings of the present study in which the exposure to both MeHg and I-Hg was low, we conclude that the exposure to both forms of mercury is higher before birth than during the breast-feeding period, and that MeHg seems to contribute more than I-Hg to infant exposure postnatally via breast milk.     

Is perceived nervousness and anxiety a predictor of premature mortality and severe morbidity? A longitudinal follow up of the Swedish survey of living conditions

STUDY OBJECTIVE: To find out if people perceiving nervousness, uneasiness, and anxiety have excess risks of premature death and severe morbidity. DESIGN, SETTING, PARTICIPANTS: Random samples of the Swedish population aged 16-74 years in 1980-81, 1988-89, and 1995-96 were followed up for 5 and 10 years with regard to deaths and hospital admissions for different causes. Relative risks were estimated by Poisson regression, comparing those who reported perceived nervousness, uneasiness, and anxiety with those who did not and adjustments were made for baseline characteristics as age, education, smoking, and longstanding illness. MAIN RESULTS: Perceived nervousness, uneasiness, and anxiety was strongly related to subsequent risks of suicide attempt and psychiatric disease. Those perceiving severe complaints of anxiety had a relative risk (fully adjusted) for suicide attempt of 9.2 (95% CI 3.0 to 28.8) for men and 3.1 (1.4 to 7.1) for women. Even for less severe complaints, there was a significant, but less pronounced excess risk. These negative feelings were also associated with later risks for all cause mortality, hospital care, and ischaemic heart disease, although to a lesser extent and more strongly among men. Unchanged relative risks over time shows no trend in response attitude and perceived anxiety seems to be a better predictor of a negative health outcome than self reported longstanding illness. CONCLUSIONS: Positive responses to self report survey questions about anxiety/nervousness are associated with adverse health outcomes, particularly hospital admission for deliberate self harm. This is an alarming signal bearing in mind the rapid increase in prevalence of perceived anxiety in the Swedish society.     

Violence against women

Violence against women is now well recognised as a public health problem and human rights violation of worldwide significance. It is an important risk factor for women's ill health, with far reaching consequences for both their physical and mental health. This glossary aims to describe various forms of interpersonal violence that are directed towards women and girls. Terms and basic concepts used in research and policy on this public health problem will be explained.     

Photopheresis for the treatment of refractory renal graft rejection

Acute rejection episodes still occur after kidney transplantation in spite of modern immunosuppressive protocols including combined tacrolimus, mycophenolate mofetil, and prednisolone. The authors present seven cases of biopsy-proven acute rejection after kidney transplantation refractory to conventional rejection therapy with repeated pulses of high-dose steroids followed by polyclonal or monoclonal antibodies that responded well to photopheresis treatment. Photopheresis is an atoxic immunomodulatory apheresis-based treatment with no generalized immunosuppressive action; rather, it is directed at suppressing donor-specific T-cell clones. At the last follow-up, 9 to 43 months after transplantation, all patients had functioning grafts, with serum creatinine levels ranging from 105 to 312 microM. The authors conclude that photopheresis treatment contributed to the favorable outcome. Therefore, the authors are presently designing a prospective, randomized trial to evaluate the effect of photopheresis as an adjuvant prophylactic treatment after renal transplantation.     

A short-form questionnaire identified genital organ prolapse

OBJECTIVE: We constructed a simple questionnaire that, with a minimum of questions, could accurately and reliably identify women with genital organ prolapse. STUDY DESIGN AND SETTING: Two hundred women with confirmed genital organ prolapse and 199 outpatients with various gynecologic symptoms but no objective prolapse answered 13 questions perceived to be valuable for the diagnosis. With stepwise backward logistic regression, the discriminatory ability of a successively abbreviated set of questions was assessed. The resulting short questionnaire was tested in a new population-based sample of 282 women participating in a screening survey. RESULTS: A final five-item questionnaire retained 94% of the predictive value of all 13 questions and had 92.5% sensitivity and 94.5% specificity in the first group of women. When the questionnaire was used in the subsequent population-based survey, the sensitivity and specificity values were 66.5% and 94.2%, respectively. Most missed cases had stage I prolapse. CONCLUSION: Although the sensitivity of the test was moderate, the specificity, and hence the ability to rule in cases, was satisfactory. The test is suitable for case finding in epidemiologic studies.
