    Prognostic value of the Rose questionnaire: a validation with future coronary events in the SMART study

    Aim: The Rose questionnaire was developed in epidemiological studies to obtain a reproducible diagnosis of angina pectoris. We studied the prognostic value of this questionnaire with respect to the occurrence of future coronary events. Methods and results: We studied 7916 consecutive patients (mean age 56 years; 67% men) with clinically manifest vascular disease or cardiovascular risk factors, enrolled in the Second Manifestations of ARTerial disease (SMART) study from 1996 to 2009. At inclusion, all patients completed the Rose questionnaire. We investigated the prognostic value of four definitions of angina pectoris that were based on the following elements of the questionnaire (1) the full questionnaire; (2) three key questions concerning chest pain; (3) one question about discomfort or pain in the chest; (4) two questions about complaints when slowing down or stopping activities (the definition that is used in the SMART study). All patients were followed for new coronary events and interventions for an average of 4.6 years. Analyses were with multivariable Cox regression models. Discriminatory ability of the four definitions as assessed with areas under the receiver-operator characteristics curves was similar (range 0.708–0.726) for coronary events in isolation as well as in combination with coronary interventions. The models were assessed for their ability to improve risk stratification compared with each other; differences between definitions are small. Conclusion: Our data implicate that the use of a subset of questions of the Rose questionnaire performs equally well compared with the full Rose questionnaire regarding the prediction of coronary events.
    Trends in vascular risk factors and medication use in patients with various manifestations of vascular diseases or type 2 diabetes mellitus from 1996 to 2007: the Second Manifestations of Arterial Disease (SMART) Study

    Aims: To investigate time trends in vascular risk factors and medication use for patients referred to a vascular specialist with manifest vascular disease or type 2 diabetes mellitus (DM2). Methods and results: Change in risk factor profile and medication use at referral over a 12-year period was evaluated and compared between patients with coronary heart disease, cerebrovascular disease, peripheral arterial disease, abdominal aortic aneurysm, and DM2, who participated in the Second Manifestations of ARTerial disease study in the period of 1996-2007. A total of 4731 patients were included (mean age 59+/-11 years, 75% male) in the period 1996-2007. Obesity (body mass index >=30 kg/m2) prevalence increased from 14 to 24%, and no change in smoking behavior was observed. The prevalence of hyperlipidemia (total cholesterol >=4.5 mmol/l or low-density lipoprotein cholesterol >=2.5 mmol/l) at referral declined from 92% in 1996-1997 to 45% in 2006-2007. The proportion of patients with blood pressure above 140/90 mmHg decreased from 66 to 51%. The use of lipid-lowering, blood pressure-lowering, and antithrombotic medication at referral increased over the observation period. Conclusion: An improvement in risk factor profile was seen in patients referred with manifest vascular disease or DM2 over a 12-year period. Nevertheless, the prevalence of modifiable risk factors is still high leaving patients at elevated vascular risk
    Tolerance of frugivorous birds to habitat disturbance in a tropical cloud forest

    In view of the continued decline in tropical forest cover around the globe, forest restoration has become a key tool in tropical rainforest conservation. One of the main - and least expensive - restoration strategies is natural forest regeneration. By aiding forest seed influx both into disturbed and undisturbed habitats, frugivorous birds facilitate forest regeneration. This study focuses on the tolerance of a frugivorous bird community to anthropogenic habitat disturbance within the broader context of natural forest regeneration with conservation purposes. It was carried out in the tropical cloud forest of Costa Rica's Talamanca Mountains. Bird community response and tolerance to habitat disturbance was assessed by comparing bird presence and densities along a disturbance gradient, ranging from open pastures to closed mature forests. Birds were censused along nine transects applying the variable width line transect procedure. Forty relevant frugivorous bird species were observed during 102 h of survey time. Densities were calculated for 33 species; nine species responded negatively to increasing level of disturbance and nine others positively. Results indicate that large frugivores are generally moderately tolerant to intermediate, but intolerant to severe habitat disturbance, and that tolerance is often higher for medium and small frugivores. It appears that moderately disturbed habitats in tropical cloud forests are highly suitable for restoration through natural regeneration aided by frugivorous birds. Due to a lack of large forest seed dispersers, severely disturbed habitats appear less suitable

    Distribution and ecology of pollen lodged within the Latin American Pollen Database

    The cornerstone of palaeoecological research, concerned with vegetation dynamics over the recent geological past, is a good understanding of the present-day ecology and distribution of the taxa. This is particularly necessary in areas of high floral diversity such as Latin America. Vegetation reconstructions, based on numerous pollen records, now exist with respect to all major vegetation associations from Latin America. With this ever-increasing number of sedimentary records becoming available, there is a need to collate this information and to provide information concerning ecology and distribution of the taxa concerned. The existing Latin American Pollen Database (LAPD) meets the first of these needs. Information concerning the ecology and distribution of the parent taxa responsible for producing the pollen, presently lodged within the LAPD, is the focus of this paper. The `dictionary' describes the ecology and distribution of the parent taxa responsible for producing pollen identified within sedimentary records. These descriptions are based on a wide range of literature and extensive discussions with members of the palaeoecological community working in different parts of Latin America investigating a range of different vegetation types.
