1. INTRODUCTION The modelling problem addressed in this paper has been called correlated failure-time modelling, multivariate survival modelling, multiple spells modelling, or a recurrent events problem, and is studied in biomedical Generally this type of modelling is required for data that arise in time-to-event studies when two or more events happen to the same subject. In such a case, the fa...

An understanding of the limit on potential predictability is crucial for developing appropriate tools for extended-range prediction of active/break spells of the Indian summer monsoon (ISM). The global low-frequency changes in climate modulate the annual cycle of the ISM and can influence the intrinsic predictability limit of the ISM intraseasonal oscillations (ISOs). Using 104-year (1901–2004)...

The programs of the International Monetary Fund were originally designed to provide short-term assistance to countries implementing policies to address balance of payments disequilibria. In recent decades, however, the Fund has instituted new facilities with longer time horizons, while many developing countries have adopted consecutive programs. As a result, the length of time spent by countrie...

This study examined associations between mother-infant nighttime interactions and mother-infant attachment when infants were 12 months old. Forty-four mother-infant pairs participated in this study. For three consecutive nights at home, babies were observed in their cribs using a digital video system. Mothers reported on their nighttime interactions with their babies using a self-report diary a...

Tissue or nerve injury can dramatically alter the transmission of sensory stimuli by spinal cord neurons, so that a light touch produces pain. The discovery that peptide products of prepronociceptin processing either facilitate or inhibit these mechanisms suggests novel approaches to treating these conditions.

Introduction: In this study, the patients diagnosed with breath holding spell (BHS) or anoxic epileptic seizures and initiated at least one out of iron piracetam levetiracetam therapies were evaluated. Material Methods: We retrospectively evaluated 194 BHS patients. Iron therapy was in case deficiency anemia ferritin values under 12 ng/dl even if there no anemia. The having anemia, low administ...

BACKGROUND There is substantial evidence that mortality increases in low temperatures. Less is known about the role of prolonged cold periods denoted as cold spells. OBJECTIVE We conducted the first systematic review and meta-analysis to summarize the evidence on the adverse health effects of cold spells in varying climates. DATA SOURCES AND EXTRACTION Four databases (Ovid Medline, PubMed, ...

CONTEXT Sick leave is a major problem in public health. The Karasek demands/control/social support/strain (JDCS) model has been largely used to predict a wide range of health outcomes and to a lesser extent sickness absence. STUDY OBJECTIVE The aim of the study was to test the predictive power of the JDCS model in relation with one year incidence of sick leave in a large cohort of workers. ...

OBJECTIVES Large socioeconomic differences exist in disease and mortality. This paper describes the distribution of specific medical reasons for sickness absence by grade of employment in the Whitehall II study and validates the medical reason by comparison with general practitioners' records. METHODS Analysis of sickness absence data on 5620 male and female civil servants aged 35-55 years. D...
