Think global, act local: using a translocal approach to understand community-based organisations' responses to planetary health crises during COVID-19.

Little is known on how community-based responses to planetary health crises, such as the COVID-19 pandemic, can integrate concerns about livelihoods, equity, health, wellbeing, and the environment. We used a translocal learning approach to co-develop insights on community-based responses to complex health and environmental and economic crises with leaders from five organisations working with communities at the front line of intersecting planetary health challenges in Finland, India, Kenya, Peru, and the USA. Translocal learning supports collective knowledge production across different localities in ways that value local perspectives but transcend national boundaries. There were three main findings from the translocal learning process. First, thanks to their proximity to the communities they served, community-based organisations (CBOs) can quickly identify the ways in which COVID-19 might worsen existing social and health inequities. Second, localised CBO actions are key to supporting communities with unique challenges in the face of systemic planetary health crises. Third, CBOs can develop rights-based, ecologically-minded actions responding to local priorities and mobilising available resources. Our findings show how solutions to planetary health might come from small-scale community initiatives that are well connected within and across contexts. Locally-focused globally-aware actions should be harnessed through greater recognition, funding, and networking opportunities. Globally, planetary health initiatives should be supported by applying the principles of subsidiarity and translocalism.

Local stakeholder perceptions of forest degradation: Keys to sustainable tropical forest management.

Land use policies and planning in Latin America have been partially successful in halting deforestation yet have not stopped forest degradation. Here, we study the different stakeholders' perspectives of the drivers of forest degradation. We use Colombia as a case study for understanding synergies and trade-offs of the sustainable development goals (SDGs) and analyzed what the most important causes are, to whom it matters, and their regional contribution. We identified a common perception, but miscommunication and misunderstandings occur between local- and national-level actors in terms of their views on responsibilities and rates of change. The results are a call for action. Cross-scale governance is necessary to improve the design and implementation of policies for forest management at the subnational and local levels and to ensure that we move toward sustainable development without worsening existing inequalities. It is essential that countries provide the enabling conditions to develop a coherent governing framework.

Fire-induced loss of the world's most biodiverse forests in Latin America.

Fire plays a dominant role in deforestation, particularly in the tropics, but the relative extent of transformations and influence of fire frequency on eventual forest loss remain unclear. Here, we analyze the frequency of fire and its influence on postfire forest trajectories between 2001 and 2018. We account for ~1.1% of Latin American forests burnt in 2002-2003 (8,465,850 ha). Although 40.1% of forests (3,393,250 ha) burned only once, by 2018, ~48% of the evergreen forests converted to other, primarily grass-dominated uses. While greater fire frequency yielded more transformation, our results reveal the staggering impact of even a single fire. Increasing fire frequency imposes greater risks of irreversible forest loss, transforming forests into ecosystems increasingly vulnerable to degradation. Reversing this trend is indispensable to both mitigate and adapt to climate change globally. As climate change transforms fire regimes across the region, key actions are needed to conserve Latin American forests.

Reporte de caso: Manejo anestésico en un paciente pediátrico con ictiosis más deshidratación grave / Case report: Anesthetic management of an infant patient with ichthyosis plus severe dehydration

INTRODUCTION: Ichthyosis are hereditary disorders of keratinization which are characterized for the presence of hyperkeratosis and/or peeling. This disorder group can put in danger the life of the patient because of the severe alteration of the skin barrier, associated with a severe transdermic loss of water, different grades of hypothermia and a hypernatremic dehydration. OBJECTIVE: Introducing the clinic case of an infant patient with the diagnosis of ichthyosis plus severe dehydration who is scheduled for placement of CVC. CLINICAL CASE: Male infant, 3 months old, with the diagnosis of ichthyosis and severe dehydration, scheduled for placement of CVC. CONCLUSIONS: Due to the urgency of our patient, who presented severe dehydration, an inhaled general anesthesia with sevoflurane and oxygen was decided, without instrumenting the airway which in these patients has the risk of being potentially difficult, from the placement of the face mask itself, until finding lesions within the oral cavity, ventilatory assis- tance should be maintained by the pediatric anesthesiologist, once venous access is achieved, the fluids restitution is performed with loads of 10 to 20 ml/kg of the patient's weight, hyperthermia was controlled with physical means.

INTRODUCCIÓN: Las ictiosis son trastornos hereditarios de la queratinización caracterizadas por la presencia de hiperqueratosis y/o descamación. Este grupo de patologías pueden poner en peligro la vida del paciente debido a la severa alteración de la barrera cutánea, asociada a intensa pérdida transepidérmica de agua, diferentes grados de hipotermia y la deshidratación hipernatrémica. OBJETIVO: Presentar un caso clínico de paciente lactante menor con diagnóstico de ictiosis, cursando un cuadro grave por deshidratación, al que se le instala un CVC. CASO CLÍNICO: Lactante masculino, 3 meses de edad, con diagnóstico de ictiosis y deshidratación grave programado para colocación de CVC. CONCLUSIONES: Debido a la urgencia del paciente quien presentaba un caso de deshidratación severa se decide anestesia general inhalada con sevoflurano y oxígeno, sin instrumentación de la vía área, la cual en estos pacientes tiene el riesgo de ser potencialmente difícil, desde la propia colocación de la mascarilla facial hasta encontrar lesiones dentro de la cavidad oral; se debe mantener la asistencia ventilatoria por el anestesiólogo pediatra, una vez logrado el acceso venoso se procede a la restitución hídrica con cargas de 10 a 20 ml/kg de peso del paciente, el control de la hipertermia fue con medios físicos.

Evolving building blocks of rhythm: how human cognition creates music via cultural transmission.

Why does musical rhythm have the structure it does? Musical rhythm, in all its cross-cultural diversity, exhibits commonalities across world cultures. Traditionally, music research has been split into two fields. Some scientists focused on musicality, namely the human biocognitive predispositions for music, with an emphasis on cross-cultural similarities. Other scholars investigated music, seen as a cultural product, focusing on the variation in world musical cultures. Recent experiments found deep connections between music and musicality, reconciling these opposing views. Here, we address the question of how individual cognitive biases affect the process of cultural evolution of music. Data from two experiments are analyzed using two complementary techniques. In the experiments, participants hear drumming patterns and imitate them. These patterns are then given to the same or another participant to imitate. The structure of these initially random patterns is tracked along experimental "generations." Frequentist statistics show how participants' biases are amplified by cultural transmission, making drumming patterns more structured. Structure is achieved faster in transmission within rather than between participants. A Bayesian model approximates the motif structures participants learned and created. Our data and models suggest that individual biases for musicality may shape the cultural transmission of musical rhythm.

DNA damage induced by coal dust, fly and bottom ash from coal combustion evaluated using the micronucleus test and comet assay in vitro.

Coal mining and combustion generating huge amounts of bottom and fly ash are major causes of environmental pollution and health hazards due to the release of polycyclic aromatic hydrocarbons (PAH) and heavy metals. The Candiota coalfield in Rio Grande do Sul, is one of the largest open-cast coal mines in Brazil. The aim of this study was to evaluate genotoxic and mutagenic effects of coal, bottom ash and fly ash samples from Candiota with the comet assay (alkaline and modified version) and micronucleus test using the lung fibroblast cell line (V79). Qualitative and quantitative analysis of PAH and inorganic elements was carried out by High Performance Liquid Chromatography (HPLC) and by Particle-Induced X-ray Emission (PIXE) techniques respectively. The samples demonstrated genotoxic and mutagenic effects. The comet assay modified using DNA-glicosilase formamidopirimidina (FPG) endonuclease showed damage related to oxidative stress mechanisms. The amount of PAHs was higher in fly ash followed by pulverized coal. The amount of inorganic elements was highest in fly ash, followed by bottom ash. It is concluded that the samples induce DNA damage by mechanisms that include oxidative stress, due to their complex composition, and that protective measures have to be taken regarding occupational and environmental hazards.

Effects of Night-Time Use of Rotigotine on Nocturnal Symptoms in Parkinson's Disease.

Objectives. This open-label study assessed the efficacy and safety of exclusive night-time administration of transdermal rotigotine in patients with nocturnal and early morning PD symptoms. Methods. Patients with PD and nocturnal and early morning symptoms received transdermal rotigotine patches (2-16 mg/24 h) applied in the evening and removed in the morning for 3 months. Sleep disturbance was assessed with modified Parkinson's Disease Sleep Scale (PDSS-2). Other outcomes included a pain visual analogue scale (VAS) and short-form Parkinson's Disease Questionnaire (PDQ-8) for quality of life. Results. 74 patients completed treatment in this study. At the end of treatment, PDSS-2 total score had improved by mean 10.9 points from baseline (p < 0.001). All three PDSS-2 domain scores (sleep disturbances, nocturnal motor symptoms, and nocturnal symptoms) were also significantly improved by 41%, 56%, and 48%, respectively (p < 0.001). VAS-pain score decreased from 3.2 to 2.3 (p < 0.001). PDQ-8 score decreased from 23.8 to 18.1 (p < 0.001). The most frequently reported adverse events included nausea (9%), anxiety (4%), and dizziness (4%). Conclusions. Night-time administration of transdermal rotigotine is an effective and well tolerated treatment for nocturnal symptoms in patients with PD.

Transdermal Rotigotine Improves Sleep Fragmentation in Parkinson's Disease: Results of the Multicenter, Prospective SLEEP-FRAM Study.

Sleep disturbances occur frequently in patients with Parkinson's disease (PD). The aim of this study was to investigate the effects of rotigotine on sleep fluctuations in a sample of PD patients with self-reported complaints of nocturnal awakenings. This prospective, open-label, observational, and multicenter study enrolled consecutive outpatients with PD and administered rotigotine (mean dose 8.9 mg/day) for 3 months. The primary endpoint was the change from baseline in sleep fragmentation, assessed using the sleep maintenance subscale score of the Parkinson's Disease Sleep Scale (PDSS). The newly designed Parkinson's Disease Sleep Fragmentation Questionnaire (PD-SFQ) was used to measure other sleep parameters. A total of 62 patients were enrolled (mean age 70.2 years; 66% male). At 3 months, rotigotine significantly improved sleep fragmentation from baseline on the PDSS-2 sleep maintenance subscale (from 3.4 ± 0.9 to 1.9 ± 1.4; P < 0.0001). Rotigotine also significantly improved nocturnal motor symptoms (P < 0.0001), restless legs-like symptoms (P < 0.005), and nocturia (P = 0.004). Rotigotine significantly improved self-reported complaints of sleep fragmentation in PD patients and could be a useful treatment to improve this specific sleep problem in PD. However, these results are based on a small and clinically heterogeneous sample so they must be taken cautiously.

Leiomyoma fibrosis inhibited by liarozole, a retinoic acid metabolic blocking agent.

OBJECTIVE: To study the influence of liarozole on leiomyoma cell proliferation and extracellular matrix (ECM) gene expression in immortalized leiomyoma cells. DESIGN: Laboratory study. SETTING: University hospital. PATIENT(S): None. INTERVENTION(S): Tissue culture, real-time reverse transcription-polymerase chain reaction, Western blot. MAIN OUTCOME MEASURE(S): Proliferation, messenger RNA (mRNA), and ECM protein expression. RESULT(S): Proliferation of leiomyoma cells was inhibited by treatment with liarozole at suprapharmacologic concentrations. The mRNA and protein expression of COL1A1, COL4A2, versican, fibromodulin, and fibronectin was increased in untreated leiomyoma cells compared with untreated patient-matched myometrial cells. Extracellular matrix mRNA expression was decreased in a dose-dependent manner in leiomyoma cells treated with pharmacologic concentrations of liarozole. In addition, myometrial cells treated with liarozole demonstrated no statistically significant alteration in ECM regulation. CONCLUSION(S): Liarozole inhibited ECM protein production at pharmacologic concentrations in immortalized human leiomyoma cells. Retinoic acid metabolic blocking agents represent a potential therapeutic drug family for human leiomyomas.
