Evaluating the Effectiveness of Online Educational Modules and Interactive Workshops in Alleviating Symptoms of Mild to Moderate Depression: A Pilot Trial

Introduction: Depression is a common health concern in primary care with barriers to treatment well documented in the literature. Innovative online psychoeducational approaches to address barriers to care have been well received and can be cost effective. This pilot trial evaluated the effectiveness of an online psychoeducation curriculum intended to alleviate symptoms of depression while utilizing minimal staff resources. Methods: A small (n=29) randomized control pilot study was conducted. Online psychoeducational content was delivered in 5 to 10-minute videos over 8weeks. Participants engaged in moderated discussions on workshop topics. The Patient Health Care Questionnaire (PHQ-9) was used to measure pre/ post scores. Two Likert scale questions were used to determine subjective changes in understanding of depression and coping skills. Results: Paired T-test analysis showed an average PHQ-9 improvement of 4.37 (P=.01) in the intervention arm and 1.81 (P=.172) in the control group. No significant difference in delta PHQ-9 score was found between groups via difference in difference analysis (P=.185). Effect size was 0.59. No improvement in Likert scores for question 1 or 2 were detected by paired T test in either group. Conclusion: This pilot trial of interactive online psychoeducational content shows initial promise as there was a significant improvement in PHQ-9 scores within the intervention arm. The comparison of delta scores between intervention and control arms was not statistically significant although this is likely due to the underpowered nature of the pilot trial. This data trend justifies the need for a larger validation trial of this intervention

Undominated Sequences of Integrable Functions

[EN] In this paper, we investigate to what extent the conclusion of the Lebesgue dominated convergence theorem holds if the assumption of dominance is dropped. Specifically, we study both topological and algebraic genericity of the family of all null sequences of functions that, being continuous on a locally compact space and integrable with respect to a given Borel measure in it, are not controlled by an integrable function.Luis Bernal-Gonzalez, Maria del Carmen Calderon-Moreno, and Jose A.

Landslides in the Andes and the need to communicate on an interandean level on landslide mapping and research

[EN] --- Landslides in the Andes are some of the highest natural threats to society with single events killing up to several thousand people. Landslide mapping and landslide research became a more widely spread discipline in geosciences in the Andean countries. However efforts today by far do not match the threat and both more investigations and more mapping activities are needed to support decision makers in land use planning. In this communication we discussed five key issues that we suggest to focus on in upcoming years: Impact of climatic change on landslides occurrence, landslides susceptibility and hazard maps, prediction of megalandslides, seismically triggered landslides, and temporal spatial distribution of mud and debris flows potential.[ES] --- Los deslizamientos en los Andes son unas de las mayores amenazas naturales a la sociedad, con eventos individuales que han causado la muerte de varios miles de personas. El mapeo e investigación de deslizamientos se convirtió en una disciplina ampliamente difundida en los países andinos. Sin embargo, los esfuerzos actuales no se corresponden aún con la amenaza, y más investigaciones y mapeo son necesarios para apoyar a los tomadores de decisiones en la planificación de usos del suelo. En esta comunicación se discuten cinco temas clave en los que se sugiere poner el foco en los próximos años: el impacto del cambio climático en la ocurrencia de deslizamientos, mapas de peligro y susceptibilidad a deslizamientos, predicción de megadeslizamientos, deslizamientos disparados sísmicamente, y la potencial distribución espacio-temporal de flujos de barro y detritos

Desalination brine effects beyond excess salinity: Unravelling specific stress signaling and tolerance responses in the seagrass Posidonia oceanica

Desalination has been proposed as a global strategy for tackling freshwater shortage in the climate change era. However, there is a concern regarding the environmental effects of high salinity brines discharged from desalination plants on benthic communities. In this context, seagrasses such as the Mediterranean endemic and ecologically important Posidonia oceanica have shown high vulnerability to elevated salinities. Most ecotoxicological studies regarding desalination effects are based on salinity increments using artificial sea salts, although it has been postulated that certain additives within the industrial process of desalination may exacerbate a negative impact beyond just the increased salinities of the brine. To assess the potential effect of whole effluent brines on P. oceanica, mesocosm experiments were conducted within 10 days, simulating salinity increment with either artificial sea salts or brines from a desalination plant (at 43 psμ, 6 psμ over the natural 37 psμ). Morphometrical (growth and necrosis), photochemical (PSII chlorophyll a fluorometry), metabolic, such as hydrogen peroxide (H2O2), thiobarbituric reactive substances (TBARS) and ascorbate/dehydroascorbate (ASC/DHA), and molecular (expression of key tolerance genes) responses were analyzed in each different treatment. Although with a still positive leaf growth, associated parameters decreased similarly for both artificial sea salt and brine treatments. Photochemical parameters did not show general patterns, although only P. oceanica under brines demonstrated greater energy release through heat (NPQ). Lipid peroxidation and upregulation of genes related to oxidative stress (GR, MnSOD, and FeSOD) or ion exclusion (SOS3 and AKT2/3) were similarly incremented on both hypersalinity treatments. Conversely, the ASC/DHA ratio was significantly lower, and the expression of SOS1, CAT, and STRK1 was increased under brine influence. This study revealed that although metabolic and photochemical differences occurred under both hypersalinity treatments, growth (the last sign of physiological detriment) was similarly compromised, suggesting that the potential effects of desalination are mainly caused by brine-associated salinities and are not particularly related to other industrial additives.This investigation was funded by Marie Skłodowska-Curie Action (888415) granted to C.A.
