RESUMO

Introduction Gardening is a healthy activity that promotes nutrition and satisfaction, with positive impacts on patients with chronic diseases, including patients with obesity, diabetes, and cardiovascular disease. Hospital-based gardening programs may provide opportunities to introduce patients to gardening. However, few studies have included participant experience as a metric of evaluation. The objective of this study was to explore participant experience in a hospital-based gardening intervention designed for individuals with metabolic syndrome. Methods This study was a qualitative evaluation of free text responses from four questions included in post-participation questionnaires from 59 community-dwelling adults who participated in a hospital-based garden program located at the University of Vermont Medical Center in 2020 and 2021. Eligible participants included a convenience sample of novice gardeners with self-reported hypertension, diabetes, pre-diabetes, or overweight/obesity. We used an interpretative phenomenological approach to analyze the questionnaire data. The phenomenological cycle for each of the questions included: 1) reading and re-reading participant responses, 2) exploratory noting, 3) constructing experimental statements, 4) searching for connections across statements, and 5) naming the themes. This process also involved working with individual question-level themes to develop group themes across questions. Results This dataset was one of positivity about gardening, new information gleaned, and the quality of instruction. Several themes and codes emerged: program implementation (new knowledge, new skills, new connections, instructor ability, climate), self-efficacy (confidence, vicarious experience, mastery experience, verbal persuasion), and future change (behavior change, future issues/problem-solving, passing it on). Conclusion This study supports analyzing participant experience as part of hospital-based gardening interventions. We found positivity around program implementation, increased self-efficacy, and intentions to change behavior in ways that support healthy lifestyles.

RESUMO

Bacteria can form biofilms that consist of multicellular communities embedded in an extracellular matrix (ECM). In Bacillus subtilis, the main protein component of the ECM is the functional amyloid TasA. Here, we study further the roles played by TasA in B. subtilis physiology and biofilm formation on plant leaves and in vitro. We show that ΔtasA cells exhibit a range of cytological symptoms indicative of excessive cellular stress leading to increased cell death. TasA associates to the detergent-resistant fraction of the cell membrane, and the distribution of the flotillin-like protein FloT is altered in ΔtasA cells. We propose that, in addition to a structural function during ECM assembly and interactions with plants, TasA contributes to the stabilization of membrane dynamics as cells enter stationary phase.

RESUMO

BACKGROUND: Primary malignant pleural effusion has been reported in about 134 cases of multiple myeloma (MM). Associated pleural effusions in cases of MM portend a poor prognosis and identifying them is highly relevant. Reported is the case of a man diagnosed with MM who developed primary myelomatous pleural effusion in the setting of multiple relapses and subsequent mortality within 2 months of the pleural effusion diagnosis. PRESENTATION: A 61-year-old African American man was diagnosed with MM in 2011. He received induction therapy of lenalidomide and dexamethasone and an autologous stem cell transplant in 2012. Over the next 5 years, the patient went through alternating periods of remission and relapse that were treated with two rounds of thoracic spine radiation therapy and chemotherapeutic agents. In September 2017, the patient presented with worsening dyspnea and was found to have pleural effusion. Fluid analysis showed plasma cell dyscrasia. Fluid drainage was performed, then the patient was discharged after 1 week which was followed by rapid re-accumulation of fluid and rehospitalization about 10 days after discharge. The patient passed away a few weeks after the second admission. CONCLUSION: Pleural effusion carries a differential diagnosis which may include malignancy but is commonly thought to be less specific to multiple myeloma but should still remain in the differential diagnosis. To our knowledge, this is the first case of myelomatous pleural effusion (MPE) that was reported after multiple relapses of MM. MPE is a very rare complication of MM, and its presence is a strong indicator of imminent mortality and need for comfort care in case of multiple relapses. End-stage pleural effusion in MM in the setting of proteasome inhibitor adds more therapeutic and diagnostic challenges.
