Adverse psychological outcome in women with coronary artery disease.

OBJECTIVES: To investigate gender differences on psychological outcome following cardiac disease, and to identify predictors of psychological distress. METHODS: In total, 536 consecutive cardiac patients ≤70 years were identified from medical records to participate in the study: 36 of them proved to have died since the index event. The mean time since the index event was one year and seven months. Of the 500 patients, 357 (71%) agreed to attend an interview on biomedical risk factors and fill in a psychological questionnaire. Complete psychological data were available for 287 (80%) patients. RESULTS: Women scored significantly higher on anxiety, depression, vital exhaustion and social inhibition, and lower on wellbeing compared with men. Gender, age, percutaneous transluminal coronary angioplasty, smoking and admission for a recurrent event since the index event were independent predictors of psychological outcome. CONCLUSION: These results add to current knowledge on gender differences and show that women have an adverse outcome on a range of psychological variables. This has implications for secondary prevention and rehabilitation. Longitudinal studies are needed to assess the implications of adverse psychological outcome in women on prognosis.

Significance of coconut husk pits as larval habitats of Culex quinquefasciatus (Say) in the filariasis endemic coastal belt of Sri Lanka.

Extended surveys of coconut husk pits in three districts in a study of vectors of Japanese encephalitis showed that Cx. gelidus constituted 50.9% of the larval material in Panadurra, 77.7% in Allutgama and 75.2% in Talalla. Correspondingly, Cx. quinquefasciatus was 0, 4.1 and 0 percent respectively. A similar survey in Polhena, Matara, a well known filariasis endemic village showed 72.2% Cx. gelidus and 21.2% Cx. quinquefasciatus. Analysis of past records of husk pit surveys from seven other districts gave similar results. The reason for relatively higher breeding of Cx. quinquefasciatus in the husk pits at Polhena, Matara and a suggested vector control strategy are discussed.

The susceptibility of Liberian Culex quinquefasciatus to Wuchereria bancrofti in Sri Lanka.

Strains of Culex quinquefasciatus collected in Liberia showed low susceptibility to Wuchereria bancrofti from Liberian donors. However, when the same mosquito strains were fed on W. bancrofti donors from Sri Lanka they showed equally high susceptibility as Sri Lankan C. quinquefasciatus simultaneously fed on the same donors. A Liberian strain did not respond to selection for refractoriness. Thus the strains of W. bancrofti from Liberia and Sri Lanka differ in their ability to infect specific mosquito strains and it is concluded that Liberian C. quinquefasciatus could not provide genes for use in the construction of a refractory strain intended for the replacement of Sri Lankan vector populations.
