DIET OF OILBIRDS (STEATORNIS CARIPENSIS) IN CUEVA DE LOS GUÁCHAROS NATIONAL PARK (COLOMBIA): TEMPORAL VARIATION IN FRUIT CONSUMPTION, DISPERSAL, AND SEED MORPHOLOGY

Abstract  ∙ Oilbirds (Steatornis caripensis) are specialized nocturnal frugivores that inhabit Neotropical forests and have the potential to play key ecological roles as seed dispersers. In this study, we focused on type and quantity of seeds dispersed by a population of Oilbirds in Cueva de Los Guácharos National Park (Colombia). We assessed temporal variation in diet composition, fruit nutrient composition and measured seed morphology. To do this, we used 5–10 seed traps in a cave from 2011 to 2016, conducting a 5‐day census 1–4 times each year. In 2015, we performed a census in all 12 months to document within year variation. We found seeds of 52 species (including 17 named species, 12 identified just to family, and 23 morphospecies). We found a clear dominance of Arecaceae and Lauraceae families. Intra‐annual variation in species richness reflects the fact that more biomass and higher seed numbers are deposited in the cave in periods of nesting (January–June), as well as during seasonal fruiting patterns in the region. Data on fruit contents from published literature indicated that oilbird diet includes a high representation of lipid‐rich fruits. Consumed seed size varied enormously (range: 0.01–5.99 g dry mass), the largest seeds being up to 29 mm wide and 54 mm long. Regurgitated seeds showed a negative allometric relationship between width and length. Overall, we found a diverse diet and that Oilbirds provide efficient seed dispersal in terms of seed quantity; however, many aspects of dispersal quality remain to be determined. Resumen ∙ Dieta de los Guácharos (Steatornis caripensis) en el parque nacional Cueva de Los Guácharos (Colombia): variación temporal en la cantidad de la dispersión y morfología de semillas Los guácharos (Steatornis caripensis) son aves nocturnas frugívoras especializadas que habitan bosques neotropicales y que tienen el potencial de desempeñar roles ecológicos claves como dispersoras de semillas. En este trabajo, estudiamos la dieta y la cantidad de semillas dispersadas por una población de guácharos en el Parque Nacional Natural Cueva de los Guácharos (Colombia). Para ello, evaluamos la variación temporal, comparamos la composición de lípidos y medimos la morfología de las semillas. De 2011 a 2016 dispusimos 5–10 trampas de semillas en la cueva principal del parque y llevamos a cabo censos de usualmente 5 días, 1–4 veces cada año. Adicionalmente, en 2015 hicimos censos mensuales durante todo el año. En la dieta de los guácharos encontramos semillas de 52 especies de plantas (incluyendo 17 especies, 12 taxones identificados hasta familia y 23 morfoespecies), en las cuales se reflejó una clara dominancia de las familias Arecaceae y Lauraceae. La variación intranual en la riqueza de especies de las semillas depositadas en la cueva mostró que en los periodos de anidación de los guácharos (enero a junio) se presentó el mayor número de semillas y la mayor biomasa, además una alta riqueza de especies en el primer semestre es coherente con los patrones de fructificación en la región. La dieta del guácharo incluyó una alta representación de frutos ricos en lípidos, lo cual fue inferido de la literatura publicada. Los tamaños de las semillas dispersadas variaron enormemente (peso seco entre 0.01 y 5.99 g), siendo las semillas más grandes de 29 mm de ancho y 54 mm de largo. Las semillas que fueron dispersadas mostraron una relación alométrica negativa entre el ancho y el largo. Aunque, nosotros reportamos que los guácharos tienen una dieta diversa y proveen una eficiente dispersión de semillas en términos de la cantidad, aún deben determinarse muchos aspectos de la calidad de la dispersión

Differential Impact of Child Sexual Abuse and Family History of Suicidal Behavior in High-Risk Suicidal Patients

The current study aimed to compare suicide-related variables as a function of 1) family history of suicidal behavior and 2) child sexual abuse among patients hospitalized for a suicide attempt or active suicidal ideation. Family history of suicidal behavior and child sexual abuse were examined independently and in combination as a diathesis for a high-risk suicidal phenotype. A multicenter cross-sectional study was designed to compare data obtained from 292 patients hospitalized for suicidal behavior. Demographic and clinical variables were compared among Group 1 (patients who reported both family history of suicidal behavior and child sexual abuse), Group 2 (patients who reported only family history of suicidal behavior), Group 3 (patients who reported only child sexual abuse), and Group 4 (patients who did not report family history of suicidal behavior or childhood sexual abuse). A multinomial logistic regression was used to examine suicide-related variables associated with each group and to compare differences between groups. Group 1 and 3 endorsed a higher number of previous suicide attempts and were more likely to be younger at the first suicide attempt compared to Group 4. Group differences remained after adjustment in a multinomial regression model. The current findings suggest that child sexual abuse may be more strongly related to suicide risk among high risk patients than family history of suicidal behavior.Fil: Grendas, Leandro.

Time Left for Intervention in the Suicidal Process in Borderline Personality Disorder

The objective of this study was to measure the duration of the suicidal process among patients diagnosed with Borderline Personality Disorder (BPD). The sample included 110 female patients who met DSM-IV-TR criteria for BPD and were consecutively admitted after suicide-related behavior. A total of 63 patients (58%) reported that their suicidal process lasted 10 minutes or less. After being adjusted, the β coefficient of impulsivity scales in women with a suicidal process ≤10 minutes was lower compared to those observed in women with >10 min (β = −0.03, 95% CI = −0.06 = −0.01, p < 0.01). Suicidal patients with BPD can be divided into two groups; patients who report a suicidal process less than 10 minutes show a higher degree of impulsivity.Fil: Daray, Federico Manuel.

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Systematic review of risk factors for suicide and suicide attempt among psychiatric patients in Latin America and Caribbean

OBJECTIVE: To analyze published evidence from the Latin America and Caribbean (LAC) region pertaining to risk factors for completed suicide and suicide attempts among psychiatric populations. METHODS: Potential studies were identified through systematic electronic searches in MEDLINE and LILACS. Included studies were cohort, case-control, and cross-sectional designed investigations of psychiatric samples in which suicide or a suicide attempt was reported as an outcome and evaluated with some measure of impact (odds ratio, risk ratio, or hazard ratio). Methodological quality was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations. RESULTS: Of the 2 987 identified studies, a total of 17 studies were reviewed to determine potential suicidal risk factors. Eleven studies used a case-control design, five used a cross-sectional design, and only one study used a prospective-cohort design. The main risk factors for suicide attempts in LAC included major depressive disorder (MDD), family dysfunction, and prior suicide attempt, while the main risk factors for completed suicide were male gender and MDD. The methodological quality of most of the studies was low. CONCLUSIONS: This review provides evidence that the majority of relevant risk factors for suicide and suicide attempts in the LAC region are similar to those observed in Western societies but different from those reported in Eastern societies. Studies of higher methodological quality from the region are needed to support these results
