CHANGES IN TREMATODE INFESTATION RATES ACROSS PARASEQUENCES: INSIGHTS FROM HOLOCENE DEPOSITS OF THE PO COASTAL PLAIN, ITALY
No full textPrevious work in Late Pleistocene–Holocene sequences from the Po plain revealed significant long-term fluctuations in trematode prevalence in marine environments: higher prevalence in retrogradational environments (TST) and negligible prevalence in progradational environments (HST). Here we expand upon this work by investigating traces of trematode parasitism among bivalves within parasequence sets from the Holocene brackish deposits of the Po Plain. The investigated portion of core 204-S7 is 24 m long and, from bottom to top, includes 5 m of amalgamated fluvial channel sands (latest Pleistocene) followed upwards by alternating packages of swamp and poorly drained floodplain deposits. The middle part of the core includes brackish deposits (inner to outer lagoon) accumulated through the Holocene. Using dense sampling (32 bulk samples and >1,550 specimens) of wetland and lagoonal strata from core 204-S7, we documented trematode occurrences in Abra segmentum, Loripes orbiculatus, and Cerastoderma glaucum. A randomization (10,000 iterations) at the level of individual specimens was conducted to investigate the statistical significance of the observed variability in trematode frequency. Frequencies of trematode infestation of A. segmentum were significantly elevated (p < 0.01) in samples associated with flooding surfaces and significantly depressed (p < 0.01) in samples collected from in-between flooding surfaces. Frequencies of termatode occurrences were similarly elevated around flooding surfaces in the case of L. orbiculatus. However, frequencies of trematode infestations in C. glaucum did not vary signinficantly across samples likely refelcting their low abundance. These results, documented at a much finer scale of observation within the sequence stratigraphic framework (dissecting parasequences) than in our previous studies (comparing data pooled by systems tracts), further support the hypothesis that increasing trematode prevalence is linked to transgressive cycles, a pattern now documented in shallow marine and estuarine settings, on two continents, and in both modern and fossil taxa
Bivalve Mollusks as Hosts in the Fossil Record
No full textParasites are ubiquitous in modern ecosystems, occupy one of the most
successful life modes, promote ecosystem stability, and, despite their typically
diminutive size and lack of a mineralized skeleton, are commonly identifed in the
fossil record. Bivalve mollusks have occupied marine aquatic environments since
the Cambrian, comprise an excellent fossil record, and often preserve traces of
interactions with their parasites. Here we review parasite-host interactions of living
bivalves and the record of parasitism of bivalves that reaches as far back as the
Silurian. Escalation in parasite-host bivalve interactions seems to have occurred in
both the middle Paleozoic and the late Mesozoic to Cenozoic, similar to trends
documented in other antagonistic interactions

Living Arrangement Options for People with Intellectual Disabilities: A Scoping Review
No full textThis is one of a pair of reports prepared for the Moving Ahead Project. Its partner policy review, Mapping the National Intellectual Disability Landscape (Linehan et al., 2014), outlines current disability services, practices and policies in Ireland. This rapid scoping review provides a brief overview of national and international research exploring living arrangement options for people with intellectual disabilities
Beantown Centennials at Ford Hall Forum, video recording, 5/10/2012
No full textDirector of the Boston Redevelopment Authority, Peter Meade, moderates a program celebrating Boston\u27s three exciting centennials in 2012. Author of the full-color and thoroughly researched Fenway Park: The Centennial, Saul Wisnia shares original commentary by three generations of Boston Red Sox players and fans, plus little-known stories about our favorite stadium. President & CEO of Zoo New England, John Linehan, then reveals how radically Boston\u27s zoos — and zoology itself — have changed in a century, while describing our furry friends who live there now. Finally, the Fairmont Copley Plaza\u27s Regional Vice President and General Manager, Paul Tormey, showcases the history and trivia behind Boston\u27s jewel of hospitality in the Back Bay. Join us for a conversation on Boston\u27s three incredible attractions that only comes once in a hundred years.https://dc.suffolk.edu/fhf-av/1122/thumbnail.jp
Caring for a family member with intellectual disability and epilepsy
No full textPurpose
To examine the caregiving impact of those who support a family member with intellectual disability and epilepsy.
Methods
An online, qualitative international survey was conducted via the auspices of the International Bureau of Epilepsy with various stakeholders who support individuals who have intellectual disability and epilepsy. Qualitative comments were analyzed from respondents who identified themselves as family members (n = 48; 36%) who referred specifically to the impact of supporting a family member with these combined disabilities.
Results
Four main domains, which were comprised of ten themes, were derived from the qualitative data using Braun and Clarke\u27s qualitative framework. These domains comprised (1) practical concerns, (2) disrupted family dynamics, (3) emotional burden and (4) positive experiences. In combination these themes illustrate the pervasive impact on family life for those supporting an individual with complex needs. Financial concerns, coordination and responsibility of care, diverted attention from other family members and social isolation all contributed a significant burden of care for family members. Positive aspects were, however, also cited including the closeness of the family unit and a fostering of altruistic behavior.
Conclusion
The study provides an insight into an under-researched area. The burden of caring for a family member across the lifespan has a largely negative and pervasive impact. Targeted service provision could contribute to an amelioration of the challenges faced by these families
Effectiveness and Outcomes of Dialectical Behavior Therapy and Prolonged Exposure (DBT PE) among A Naturalistic Sample of Patients Receiving Comprehensive DBT
No full textDialectical Behavior Therapy (DBT; Linehan, 1993) and Prolonged Exposure (PE; Foa et al., 2019), and the relatively new, integrated treatment, Dialectical Behavior Therapy Prolonged Exposure (DBT PE; Harned, 2022) have all shown to be efficacious in highly controlled randomized clinical trials. Limited research has investigated the effectiveness of DBT PE in naturalistic clients outside of the context rigorous controls within randomized clinical trials. As such, there is a relative lack of research on the effectiveness of DBT PE, especially in comprehensive DBT settings. This study aimed to examine the effectiveness and outcomes of DBT and Prolonged Exposure as well as characterize the number of DBT PE sessions and changes in PTSD severity over the course of DBT PE among a sample of 89 adult patients receiving comprehensive DBT services within a Linehan-certified clinic specializing in the delivery of comprehensive DBT. Specific recommendations were offered that may help improve the implementation of evidence-based assessment practices and overall clinic-wide standard operating procedures with the ultimate goal of supporting survivors in the treatment of trauma in the context of DBT.2028-01-0
