The dominant Anopheles vectors of human malaria in Africa, Europe and the Middle East: occurrence data, distribution maps and bionomic précis

<p>Abstract</p> <p>Background</p> <p>This is the second in a series of three articles documenting the geographical distribution of 41 dominant vector species (DVS) of human malaria. The first paper addressed the DVS of the Americas and the third will consider those of the Asian Pacific Region. Here, the DVS of Africa, Europe and the Middle East are discussed. The continent of Africa experiences the bulk of the global malaria burden due in part to the presence of the <it>An. gambiae </it>complex. <it>Anopheles gambiae </it>is one of four DVS within the <it>An. gambiae </it>complex, the others being <it>An. arabiensis </it>and the coastal <it>An. merus </it>and <it>An. melas</it>. There are a further three, highly anthropophilic DVS in Africa, <it>An. funestus</it>, <it>An. moucheti </it>and <it>An. nili</it>. Conversely, across Europe and the Middle East, malaria transmission is low and frequently absent, despite the presence of six DVS. To help control malaria in Africa and the Middle East, or to identify the risk of its re-emergence in Europe, the contemporary distribution and bionomics of the relevant DVS are needed.</p> <p>Results</p> <p>A contemporary database of occurrence data, compiled from the formal literature and other relevant resources, resulted in the collation of information for seven DVS from 44 countries in Africa containing 4234 geo-referenced, independent sites. In Europe and the Middle East, six DVS were identified from 2784 geo-referenced sites across 49 countries. These occurrence data were combined with expert opinion ranges and a suite of environmental and climatic variables of relevance to anopheline ecology to produce predictive distribution maps using the Boosted Regression Tree (BRT) method.</p> <p>Conclusions</p> <p>The predicted geographic extent for the following DVS (or species/suspected species complex*) is provided for Africa: <it>Anopheles </it>(<it>Cellia</it>) <it>arabiensis</it>, <it>An. </it>(<it>Cel.</it>) <it>funestus*</it>, <it>An. </it>(<it>Cel.</it>) <it>gambiae</it>, <it>An. </it>(<it>Cel.</it>) <it>melas</it>, <it>An. </it>(<it>Cel.</it>) <it>merus</it>, <it>An. </it>(<it>Cel.</it>) <it>moucheti </it>and <it>An. </it>(<it>Cel.</it>) <it>nili*</it>, and in the European and Middle Eastern Region: <it>An. </it>(<it>Anopheles</it>) <it>atroparvus</it>, <it>An. </it>(<it>Ano.</it>) <it>labranchiae</it>, <it>An. </it>(<it>Ano.</it>) <it>messeae</it>, <it>An. </it>(<it>Ano.</it>) <it>sacharovi</it>, <it>An. </it>(<it>Cel.</it>) <it>sergentii </it>and <it>An. </it>(<it>Cel.</it>) <it>superpictus*</it>. These maps are presented alongside a bionomics summary for each species relevant to its control.</p

A multicenter study of attitudinal barriers to cancer pain management.

All had received strong opioids for at least 72 h. Data was collected with the Barriers Questionnaire-II, the Brief Pain Inventory, and the European Organization for Research and Treatment of Cancer QLQ-C30.The mean (SD) age of patients was 61.68 (12.35) years and 53% were men. Most common diagnoses were gastrointestinal, lung, prostate, and breast cancer. The mean (SD) time from diagnosis was 32.24 (44.55) and 4.97 (9.64) months from start of opioid therapy. Mean (SD) pain severity was 3.19 (1.93) on a 0 to 10 scale, and 46.5% reported worst pain of 7 or higher. Attitudinal barriers had a mean (SD) of 1.95 (0.82) on a 0-5 scale, with fear of addiction as the strongest barrier across countries 2.85 (1.49). Barrier scores increased with age, and were higher among men than women. Higher barrier scores were associated with higher pain severity and interference, and lower performance status, but not with global health-QOL. Patients who had been on opioids for a shorter time reported higher barriers.Attitudinal barriers are frequent in cancer pain patients on opioids and are associated with less effective pain control.European Palliative Care Research Collaborative University of Iceland Research Fund Icelandic Nurses Association Research Fund Icelandic Cancer Society Research Fund Memorial fund of the Palliative Care at Landspitali-the National University Hospital of Iceland Scientific fund of the Oncology Department at Landspitali-the National University Hospital of Iceland Bergthora Magnusdottir and Jakob J Bjarnason Memorial Fund 6th EU program Landspitali-the National University Hospital of Iceland Research Fun
