Supervised Physical Activity Quickly Improves Social Dimension of Quality of Life in Breast Cancer Patients.

PURPOSE: The objectives of the present study was to evaluate the implementation of the program in real life and the evolution of the quality of life (QoL) in breast cancer patients after 3 months of supervised PA in real life and to determine the factors associated with changes in various QoL dimensions. METHODS: This prospective cohort study was carried out in female patients with breast cancer diagnosed within a maximum of 3 yr. QoL and physical exertion intensity during the supervised physical activity (PA) sessions were assessed by the Quality of Life Questionnaire for Cancer and Borg scale, respectively. Statistical analyses comparing QoL scores between the start and the end of supervised PA program were assessed using paired Student's t -tests. Multivariate analysis was performed by linear regression with only variables with a P value <0.15 in univariate model. RESULTS: A total of 93 patients were included in the analyses. There was a significant improvement of social functioning at T3 (∆ = 11.5; P < 0.001). The improvement of social functioning was significantly and independently associated with the Borg improvement ( ß = 2.66 ± 1.31, P = 0.046), chemotherapy ( ß = 11.03 ± 5.45, P = 0.046), hormone therapy ( ß = -13.91 ± 5.51, P = 0.013), social isolation ( ß = -14.81 ± 6.55, P = 0.026), and comorbidities ( ß = -15.32 ± 5.59, P = 0.007). CONCLUSIONS: We observed a real enthusiasm and need among patients for practicing PA supervised by a sport trainer near their home. The increase in the intensity of exercise over time contributes to the improvement of the QoL, especially on the social functioning. These results, consistent with previous literature, reinforce the importance of exercise intensity on many dimensions of QoL. In addition, patients expressed great satisfaction with the supervised program, resulting in a strong desire to maintain long-term PA.

Phlebotomine sandflies (Diptera, Psychodidae) from the Ankarana tsingy of northern Madagascar: inventory and description of new taxa.

An inventory of Phlebotomine sandflies was carried out in the Ankarana tsingy located in far northern Madagascar. A total of 723 sandflies were used for morphological, morphometric, and molecular studies (sequencing of partial cytochrome B (mtDNA) and partial 28S (rDNA)). Nine species were identified: Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, two species of the genus Grassomyia, as well as three new species described herein: Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. The recognition of these new species is strongly supported by molecular analyses. The first two of the new species could not be classified into any existing subgenus, therefore we proposed two new subgenera (Ranavalonomyia subg. nov., and Riouxomyia subg. nov.), with combinations as: Sergentomyia (Ranavalonomyia) volfi and Sergentomyia (Riouxomyia) kaltenbachi. Our study reveals important molecular variability in Se. anka, with the recognition of a population whose taxonomic status remains below that of species. Our research confirms the need to further study the specific diversity of Malagasy sandflies, which until the start of this millennium remained mostly unknown.

TITLE: Les phlébotomes (Diptera, Psychodidae) des tsingy d'Ankarana dans le nord de Madagascar : inventaire et description de nouveaux taxons. ABSTRACT: Un inventaire des Phlébotomes a été réalisé dans les tsingy d'Ankarana à l'extrême nord de Madagascar. Au total, 723 phlébotomes ont servi à des études morphologique, morphométrique et moléculaire (séquençage d'une partie du cytochrome B (ADNmt) et d'une partie de l'ADNr 28S). Neuf espèces ont été identifiées : Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, deux espèces du genre Grassomyia, ainsi que trois espèces nouvelles décrites dans ce travail : Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. L'individualisation de chacune de ces espèces nouvelles est robustement soutenue par les analyses moléculaires. Les deux premières de ces espèces nouvelles ne pouvaient pas être classées dans un sous-genre existant et nous avons proposé pour elles deux sous-genres nouveaux : Ranavalonomyia subg. nov., et Riouxomyia subg. nov, avec les combinaisons Sergentomyia (Ranavalonomyia) volfi et Sergentomyia (Riouxomyia) kaltenbachi.Notre étude révèle une variabilité moléculaire marquée chez Se. anka avec l'individualisation d'une population dont le statut taxinomique demeure populationnel. Nos travaux confirment la nécessité de poursuivre l'étude de la biodiversité des Phlébotomes qui est restée méconnue dans ce pays jusqu'au début de ce millénaire.

Toothed whale and shark depredation indicators: A case study from the Reunion Island and Seychelles pelagic longline fisheries.

Depredation in marine ecosystems is defined as the damage or removal of fish or bait from fishing gear by predators. Depredation raises concerns about the conservation of species involved, fisheries yield and profitability, and reference points based on stock assessment of depredated species. Therefore, the development of accurate indicators to assess the impact of depredation is needed. Both the Reunion Island and the Seychelles archipelago pelagic longline fisheries targeting swordfish (Xiphias gladius) and tuna (Thunnus spp.) are affected by depredation from toothed whales and pelagic sharks. In this study, we used fishery data collected between 2004 and 2015 to propose depredation indicators and to assess depredation levels in both fisheries. For both fisheries, the interaction rate (depredation occurrence) was significantly higher for shark compared to toothed whale depredation. However, when depredation occurred, toothed whale depredation impact was significantly higher than shark depredation impact, with higher depredation per unit effort (number of fish depredated per 1000 hooks) and damage rate (proportion of fish depredated per depredated set). The gross depredation rate in the Seychelles was 18.3%. A slight increase of the gross depredation rate was observed for the Reunion Island longline fleet from 2011 (4.1% in 2007-2010 and 4.4% in 2011-2015). Economic losses due to depredation were estimated by using these indicators and published official statistics. A loss of 0.09 EUR/hook due to depredation was estimated for the Reunion Island longline fleet, and 0.86 EUR/hook for the Seychelles. These results suggest a southward decreasing toothed whale and shark depredation gradient in the southwest Indian Ocean. Seychelles depredation levels are among the highest observed in the world revealing this area as a "hotspot" of interaction between pelagic longline fisheries and toothed whales. This study also highlights the need for a set of depredation indicators to allow for a global comparison of depredation rates among various fishing grounds worldwide.
