Sustainable Development versus Extractivist Deforestation in Tropical, Subtropical, and Boreal Forest Ecosystems: Repercussions and Controversies about the Mother Tree and the Mycorrhizal Network Hypothesis.

This research reviews the phenomenon of extractive deforestation as a possible trigger for cascade reactions that could affect part of the forest ecosystem and its biodiversity (surface, aerial, and underground) in tropical, subtropical, and boreal forests. The controversy and disparities in criteria generated in the international scientific community around the hypothesis of a possible link between "mother trees" and mycorrhizal networks in coopetition for nutrients, nitrogen, and carbon are analyzed. The objective is to promote awareness to generate more scientific knowledge about the eventual impacts of forest extraction. Public policies are emphasized as crucial mediators for balanced sustainable development. Currently, the effects of extractive deforestation on forest ecosystems are poorly understood, which requires caution and forest protection. Continued research to increase our knowledge in molecular biology is advocated to understand the adaptation of biological organisms to the new conditions of the ecosystem both in the face of extractive deforestation and reforestation. The environmental impacts of extractive deforestation, such as the loss of biodiversity, soil degradation, altered water cycles, and the contribution of climate change, remain largely unknown. Long-term and high-quality research is essential to ensure forest sustainability and the preservation of biodiversity for future generations.

Exploring the Hidden Complexity: Entropy Analysis in Pulse Oximetry of Female Athletes.

This study examines the relationship between physiological complexity, as measured by Approximate Entropy (ApEn) and Sample Entropy (SampEn), and fitness levels in female athletes. Our focus is on their association with maximal oxygen consumption (VO2,max). Our findings reveal a complex relationship between entropy metrics and fitness levels, indicating that higher fitness typically, though not invariably, correlates with greater entropy in physiological time series data; however, this is not consistent for all individuals. For Heart Rate (HR), entropy measures suggest stable patterns across fitness categories, while pulse oximetry (SpO2) data shows greater variability. For instance, the medium fitness group displayed an ApEn(HR) = 0.57±0.13 with a coefficient of variation (CV) of 22.17 and ApEn(SpO2) = 0.96±0.49 with a CV of 46.08%, compared to the excellent fitness group with ApEn(HR) = 0.60±0.09 with a CV of 15.19% and ApEn(SpO2) =0.85±0.42 with a CV of 49.46%, suggesting broader physiological responses among more fit individuals. The larger standard deviations and CVs for SpO2 entropy may indicate the body's proficient oxygen utilization at higher levels of physical demand. Our findings advocate for combining entropy metrics with wearable sensor technology for improved biomedical analysis and personalized healthcare.

Challenges for Plant Growth Promoting Microorganism Transfer from Science to Industry: A Case Study from Chile.

Research on the plant growth promoting microorganisms (PGPM) is increasing strongly due to the biotechnological potential for the agricultural, forestry, and food industry. The benefits of using PGPM in crop production are well proven; however, their incorporation in agricultural management is still limited. Therefore, we wanted to explore the gaps and challenges for the transfer of biotechnological innovations based on PGPM to the agricultural sector. Our systematic review of the state of the art of PGPM research and knowledge transfer takes Chile as an example. Several transfer limiting aspects are identified and discussed. Our two main conclusions are: neither academia nor industry can meet unfounded expectations during technology transfer, but mutually clarifying their needs, capabilities, and limitations is the starting point for successful collaborations; the generation of a collaborative innovation environment, where academia as well as public and private stakeholders (including the local community) take part, is crucial to enhance the acceptance and integration of PGPM on the way to sustainable agriculture.

Unraveling Reactionary Care: The Experience of Mother-Caregivers of Adults with Severe Mental Disorders in Catalonia.

In most Mediterranean countries, people diagnosed with severe mental disorders (SMDs) are typically cared for by the mother, causing a significant burden on people in this family role. Based on a broader mental health participatory action and qualitative research carried out in Catalonia (Spain) of 12 in-depth interviews and 3 focus groups, this article analyses the mother-caregivers' experience in the domestic space. The results show that patients and caregivers are engaged in a relationship of "nested dependencies", which create social isolation. This produces the conditions of "reactionary care", practices that limit the autonomy of those affected and that reproduce forms of disciplinary psychiatric institutions. We conclude that both institutional violence derived from economic rationality and that which stems from the gender mandate feed off each other into the domestic sphere. This research argues for placing care at the center of clinical practice and shows the need to consider the structural forces shaping it.

The role of pre-treatment paraaortic surgical staging for cervical cancer in the EMBRACE criteria.

Background: The State-of-the-Art Treatment for Locally Advanced Cervical Cancer (LACC) is Definite Radio-Chemotherapy based on the Image-guided intensity modulated External beam radiochemotherapy and MRI-based adaptive BRAchytherapy (EMBRACE) trial, according to the FIGO staging. This staging is based on clinical examination and imaging studies; however, there are limitations of imaging techniques which may result in adverse events or death due to insufficient or overtreatment. The aim of the study was to evaluate the feasibility and outcomes of surgical staging in LACC prior to radiotherapy (RT) to personalise target volumes for radiotherapy. Methods: From 2008 to 2018, 138 patients with FIGO 2018 stages IB3-IIIC2 cervical cancer underwent a pretherapeutic laparoscopic staging procedure. The pathological diagnosis was compared with the results of preoperative CT scan. Patients were treated with chemoradiotherapy tailored according to the staging results. Results: The mean patient age was 43 years, the mean body mass index was 27 kg/m2; most lesions were squamous cervical cancer (92%). Staging CT scan had a 77% concordance with the histological findings. Sensitivity was 29%, specificity 85%, positive predictive value 21% and negative predictive value 89%. Surgical staging led to change of stage in 24% of cases. Para -aortic dissection led to change the initially planned radiotherapy fields in 47% of the cases. Major complications included involuntary section of the inferior mesenteric artery (IMA) without clinical repercussion, an infected retroperitoneal haematoma and a symptomatic lymphocele requiring laparoscopic drainage. Conclusion: Laparoscopic staging before primary chemoradiation in patients with LACC was feasible, safe and reproducible, allowing reduction of the radiotherapy treatment volumes of patients.

The collaborative management of antipsychotic medication and its obstacles: A qualitative study.

Antipsychotic medication is the primary treatment for psychotic conditions such as schizophrenia and schizoaffective disorders; nevertheless, its administration is not free from conflicts. Despite taking their medication regularly, 25-50% of patients report no benefits or perceive this type of treatment as an imposition. Following in the footsteps of a previous initiative in Quebec (Canada), the Gestion Autonome de la Médication en Santé Mentale (GAM), this article ethnographically analyses the main obstacles to the collaborative management of antipsychotics in Catalonia (Spain) as a previous step for the implementation of this initiative in the Catalan mental healthcare network. We conducted in-depth interviews with patients (38), family caregivers (18) and mental health professionals (19), as well as ten focus groups, in two public mental health services, and patients' and caregivers' associations. Data were collected between February and December 2018. We detected three main obstacles to collaboration among participants. First, different understanding of the patient's distress, either as deriving from the symptoms of the disorder (professionals) or the adverse effects of the medication (patients). Second, differences in the definition of (un)awareness of the disorder. Whereas professionals associated disorder awareness with treatment compliance, caregivers understood it as synonymous with self-care, and among patients "awareness of suffering" emerged as a comprehensive category of a set of discomforts (i.e., symptoms, adverse effects of medication, previous admissions, stigma). Third, discordant expectations regarding clinical communication that can be condensed in the differences in meaning between the Spanish words "trato" and "tratamiento", where the first denotes having a pleasant manner and agreement, and the second handling and management. We conclude that these three obstacles pave the way for coercive practices and promote patients' de-subjectivation, named here as the "total patient" effect. This study is the first GAM initiative in Europe.

Relationship between soil nutrients and mycorrhizal associations of two Bipinnula species (Orchidaceae) from central Chile.

BACKGROUND AND AIMS: Mycorrhizal associations are influenced by abiotic and biotic factors, including climate, soil conditions and the identity of host plants. However, the effect of environmental conditions on orchid mycorrhizal associations remains poorly understood. The present study examined how differences in soil nutrient availability are related to the diversity and composition of mycorrhizal fungi associated with two terrestrial orchid species from central Chile. METHODS: For 12 populations of Bipinnula fimbriata and B. plumosa, OTU (operational taxonomic unit) richness, phylogenetic diversity and community composition of mycorrhizal fungi in root samples were estimated using internal transcribed spacer (ITS) sequences. Then, these mycorrhizal diversity variables were related to soil nutrients and host species using generalized linear models and non-metric multidimensional scaling. KEY RESULTS: Variation in OTU composition of mycorrhizal fungi among sites was explained mainly by orchid host species. Fungi in Tulasnellaceae and Ceratobasidiaceae were isolated from both orchid species, but the former were more frequent in B. fimbriata and the latter in B. plumosa. Soil nutrients and orchid host species had significant effects on OTU richness and phylogenetic diversity. Mycorrhizal diversity decreased in habitats with higher N in both species and increased with P availability only in B. fimbriata CONCLUSIONS: The results suggest that soil nutrient availability modulates orchid mycorrhizal associations and provide support for the hypothesis that specialization is favoured by higher soil nutrient availability. Inter-specific differences in mycorrhizal composition can arise due to a geographical pattern of distribution of orchid mycorrhizal fungi, host preferences for fungal partners or differential performance of mycorrhizal fungi under different nutrient availabilities. Further experiments are needed to evaluate these hypotheses.
