Trends in the extinction of carnivores in Madagascar

Tendencias de la extinción de carnívoros en Madagascar La extinción de los depredadores apicales, como los mamíferos carnívoros, puede conllevar cambios drásticos en la estructura de la red alimentaria y la dinámica de los ecosistemas. Dado que todos los mamíferos carnívoros terrestres autóctonos de Madagascar son endémicos, su extinción implica una pérdida notable de biodiversidad en este país. En el presente artículo examinamos las publicaciones sobre mamíferos carnívoros de Madagascar con el propósito de determinar cuáles son las especies que tienen mayor probabilidad de extinguirse en un futuro próximo, en vista de los factores que amenazan su supervivencia. Puntuamos cada factor en función de los efectos que ejerce en las especies. Según nuestros resultados, la especie que tiene más probabilidad de extinguirse es la mangosta rayada grande, Galidictis grandidieri, lo cual no es sorprendente porque esta especie se considera uno de los carnívoros más escasos del mundo, que habita solo en un ecosistema forestal pequeño y amenazado. Asimismo, nuestros resultados ponen de manifiesto la necesidad de disponer de datos sólidos sobre cada especie, a fin de ayudar y respaldar a las autoridades a poner en práctica medidas de conservación.The extinction of top predators, such as mammalian carnivores can lead to dramatic changes in foodweb structure and ecosystem dynamics. Since all native Malagasy terrestrial mammalian carnivores are endemic, their extinction implies a significant loss of biodiversity in Madagascar. Here we review the literature on Madagascar’s mammalian carnivores, aiming to determine which species are most likely to become extinct in the near future in view of the factors threatening their survival. We scored each factor according to its impact on the species. According to our results, the giant–striped mongoose, Galidictis grandidieri, is the most likely species to next become extinct. This is no surprise because this species is considered one of the rarest carnivores in the world, inhabiting only a small, threatened forest ecosystem. Our results emphasize the need for robust data about each species to help and support decision–makers implement conservation measures.Tendencias de la extinción de carnívoros en Madagascar La extinción de los depredadores apicales, como los mamíferos carnívoros, puede conllevar cambios drásticos en la estructura de la red alimentaria y la dinámica de los ecosistemas.

Coping styles within the family system in the chronic phase following acquired brain injury: its relation to families’ and patients’ functioning

OBJECTIVE: To investigate how the functioning of family members and the coping styles they use are related to the psychosocial functioning both of the family members and of the person who has sustained a brain injury. DESIGN: Cross-sectional study. SUBJECTS: Primary caregivers (n = 61) and other family members (n = 15) of 61 patients with brain injury. METHODS: Primary caregivers completed the Utrecht Coping List, the Life Satisfaction Questionnaire 9, and the Caregiver Strain Index. All family members completed the Family Assessment Device. Data for the patients were collected retrospectively. RESULTS: Primary caregivers who had a preference for passive coping styles reported that they experienced a lower level of family functioning, a lower quality of life, and a higher strain. Neither the coping styles nor the psychosocial outcomes of the primary caregivers were significantly associated with patients' self-reported quality of life. Furthermore, there was no correlation between the level of family functioning and a patient's quality of life. CONCLUSION: Coping styles of caregivers are important determinants for their own psychosocial functioning, but not for patients' psychosocial functioning, although causality cannot be inferred. To enhance caregivers' psychosocial functioning, rehabilitation should focus on changing their coping styles into ones that are less passive. Furthermore, distinct or additional interventions may be needed to change the patient's coping style

application of lean methodologies

Poster presentationHealthcare acquired infections (HAI) are an important cause of morbidity and mortality. Hand hygiene (HH) is one of the most effective measures for preventing HAI. However, stirring healthcare workers to comply with HH remains a challenge. Two common barriers often found are forgetfulness and the lack of time. We hypothesize that the perception of lack of time and forgetfulness stems from the pressure of too much tasks in a short period of time. Therefore, it is rational to search for efficiency and minimize waste. This study aims at exploring the use of LEAN methodologies to improve nurses’ work processes in an ICU ward. A design science research approach was used. A questionnaire was applied to the nurses followed by an observational study of an 8-hour work shift to identify nurses’ activities, processes of care, and to describe HH compliance. Next, a value stream map (VSM) was designed and the analysis performed with the nurses, which helped to identify points of possible improvement in the process of care. After this, weekly LEAN workshops were held with the objective of improving workflow efficiency. From the initial observational study, we found that a nurse may take on average 16% of their work time using the information system, and the overall rate of HH was 63%. The full compliance to HH would amount to 13% of a nurse’s workload. Three processes were identified as the most relevant HH compliance drivers: the reorganization of essential supplies, the optimal provision of medicines and monitoring equipment automatic data collection. The participant nurses defined as objectives to reduce the supplies’ delivering time and establish a stock management system. To achieve it the reorganization of the storage with the ABC method, with the nurses deciding the layout of the storage space, was essential. The use of LEAN methods permitted to detect and address improvement opportunities with significant benefits. Moreover, nurses’ participation in the process enriched the experience, helping to design a customized intervention and heightened their sense of teamwork.publishersversionpublishe

Injecção intralesional de betametasona nas estenoses benignas do esófago

Intralesional steroid injection has been used in benign oesophageal strictures to improve the results of dilatation. Most studies use triamcinolone, only a few have reported using betamethasone. Objectives: To evaluate the efficacy and safety of the combination of dilatation and intralesional betamethasone injection in benign oesophageal strictures. Methods: Cases of benign oesophageal strictures treated with dilatation and betamethasone injection between January 1st 1998 and December 31st 2004 were retrospectively analysed. Thirty-one patients (21 males, 10 females) were identified, with a mean age of 58.8 years. The most frequent aetiologies of the stenosis were post-surgical (16 patients), peptic (11 cases) and caustic (5 cases). Results: The periodic dilatation index significantly decreased (p=0.002), although there was no statistically significant variation between medium luminal diameter pre and post-treatment. There were no adverse events. Conclusion: Intralesional betamethasone injection is a safe technique which increases efficacy of endoscopic dilatation. However, no conclusions can be drawn from our study due to the small population studied

BEfree: A new psychological program for binge eating that integrates psychoeducation, mindfulness, and compassion

Background Binge eating disorder (BED) is associated with several psychological and medical problems, such as obesity. Approximately 30% of individuals seeking weight loss treatments present binge eating symptomatology. Moreover, current treatments for BED lack efficacy at follow‐up assessments. Developing mindfulness and self‐compassion seem to be beneficial in treating BED, although there is still room for improvement, which may include integrating these different but complimentary approaches. BEfree is the first program integrating psychoeducation‐, mindfulness‐, and compassion‐based components for treating women with binge eating and obesity. Objective To test the acceptability and efficacy up to 6‐month postintervention of a psychological program based on psychoeducation, mindfulness, and self‐compassion for obese or overweight women with BED. Design A controlled longitudinal design was followed in order to compare results between BEfree (n = 19) and waiting list group (WL; n = 17) from preintervention to postintervention. Results from BEfree were compared from preintervention to 3‐ and 6‐month follow‐up. Results BEfree was effective in eliminating BED; in diminishing eating psychopathology, depression, shame and self‐criticism, body‐image psychological inflexibility, and body‐image cognitive fusion; and in improving obesity‐related quality of life and self‐compassion when compared to a WL control group. Results were maintained at 3‐ and 6‐month follow‐up. Finally, participants rated BEfree helpful for dealing with impulses and negative internal experiences. Conclusions These results seem to suggest the efficacy of BEfree and the benefit of integrating different components such as psychoeducation, mindfulness, and self‐compassion when treating BED in obese or overweight women. Key Practitioner Message The current study provides evidence of the acceptability of a psychoeducation, mindfulness, and compassion program for binge eating in obesity (BEfree); Developing mindfulness and self‐compassionate skills is an effective way of diminishing binge eating, eating psychopathology and depression, and increasing quality of life in women with obesity; Integrating psychoeducation, mindfulness, and compassion seem to be effective in diminishing binge eating, with results maintained up to 6‐month postintervention

TCTEX1D4, a novel protein phosphatase 1 interactor: connecting the phosphatase to the microtubule network

Reversible phosphorylation plays an important role as a mechanism of intracellular control in eukaryotes. PPP1, a major eukaryotic Ser/Thr-protein phosphatase, acquires its specificity by interacting with different protein regulators, also known as PPP1 interacting proteins (PIPs). In the present work we characterized a physiologically relevant PIP in testis. Using a yeast two-hybrid screen with a human testis cDNA library, we identified a novel PIP of PPP1CC2 isoform, the T-complex testis expressed protein 1 domain containing 4 (TCTEX1D4) that has recently been described as a Tctex1 dynein light chain family member. The overlay assays confirm that TCTEX1D4 interacts with the different spliced isoforms of PPP1CC. Also, the binding domain occurs in the N-terminus, where a consensus PPP1 binding motif (PPP1BM) RVSF is present. The distribution of TCTEX1D4 in testis suggests its involvement in distinct functions, such as TGFβ signaling at the blood-testis barrier and acrosome cap formation. Immunofluorescence in human ejaculated sperm shows that TCTEX1D4 is present in the flagellum and in the acrosome region of the head. Moreover, TCTEX1D4 and PPP1 co-localize in the microtubule organizing center (MTOC) and microtubules in cell cultures. Importantly, the TCTEX1D4 PPP1BM seems to be relevant for complex formation, for PPP1 retention in the MTOC and movement along microtubules. These novel results open new avenues to possible roles of this dynein, together with PPP1. In essence TCTEX1D4/PPP1C complex appears to be involved in microtubule dynamics, sperm motility, acrosome reaction and in the regulation of the blood-testis barrier
