Is it as good as being in person? The effectiveness of a modified clinician facilitated buried in treasures group for hoarding disorder using video teleconferencing

The COVID-19 pandemic has necessitated the use of video-teleconferencing (VTC) for psychological treatments but VTC effectiveness studies are sparse. We examined treatment outcomes for a modified Buried in Treasures (BIT) group program for hoarding disorder (HD) delivered via VTC. Participants were 10 individuals with HD. Hoarding severity was evaluated at pre, mid, post, and six-month follow-up. Results showed significant decrease in hoarding symptoms over time (with an average decrease of 32%). The dropout rate was low (9%) and 30% of participants were fully recovered at follow-up. These results support the adaptation of in-person BIT for HD into a VTC format.

Effects of flooding on lead and cadmium speciation in sediments from a drinking water reservoir

Rímov water reservoir on the river Malse is the main source of drinking water for the town of Ceské Budejovice and for the majority of inhabitants in the South Bohemian region, Czech Republic. Changes in cadmium and lead contents in bottom sediments before and after an extensive flood on the river Malse in August, 2002 were therefore determined. A five-step sequential extraction procedure was used in order to obtain more detailed information about the influence of the flood on heavy metal retention. In order to determine the mobility of lead and cadmium, the mobility factor (MF) for these heavy metals was calculated. The mobility factor of cadmium showed a significant decrease in the upper parts of the sediment profiles after the flood (e.g., from 59.4% to 49.1%) caused by a release of cadmium especially from the exchangeable fraction. There were no significant changes in the lead mobility factor after the flood, but a decrease of lead concentration in the exchangeable fraction was observed. Presented results show that the flood led to a leaching of the heavy metals present in bottom sediments into the environment.
