Physical activity-related individual differences in functional human connectome are linked to fluid intelligence in older adults.

The study examined resting state functional connectivity (rs-FC) associated with moderate-to-vigorous physical activity (MV-PA), sedentary time (ST), TV viewing, computer use, and their relationship to cognitive performance in older adults. We used pre-intervention data from 119 participants from the Fit & Active Seniors trial. Multivariate pattern analysis revealed two seeds associated with MV-PA: right superior frontal gyrus (SFG; spanning frontoparietal [FPN] and ventral attention networks [VAN]) and right precentral (PrG) and postcentral gyri (PoG) of the somatosensory network (SN). A positive correlation between the right SFG seed and a cluster spanning default mode (DMN), dorsal attention (DAN), FPN, and visual networks (VIS) was linked to higher fluid intelligence, as was FC between the right PrG/PoG seed and a cluster in VIS. No significant rs-FC patterns associated with ST, TV viewing, or computer use were found. Our findings suggest that greater functional integration within networks implementing top-down control and within those supporting visuospatial abilities, paired with segregation between networks critical and those not critical to top-down control, may help promote cognitive reserve in more physically active seniors.

Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment.

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Proof-of-Principle Experiment on the Dynamic Shell Formation for Inertial Confinement Fusion.

In the dynamic-shell (DS) concept [V. N. Goncharov et al., Novel Hot-Spot Ignition Designs for Inertial Confinement Fusion with Liquid-Deuterium-Tritium Spheres, Phys. Rev. Lett. 125, 065001 (2020).PRLTAO0031-900710.1103/PhysRevLett.125.065001] for laser-driven inertial confinement fusion the deuterium-tritium fuel is initially in the form of a homogeneous liquid inside a wetted-foam spherical shell. This fuel is ignited using a conventional implosion, which is preceded by a initial compression of the fuel followed by its expansion and dynamic formation of a high-density fuel shell with a low-density interior. This Letter reports on a scaled-down, proof-of-principle experiment on the OMEGA laser demonstrating, for the first time, the feasibility of DS formation. A shell is formed by convergent shocks launched by laser pulses at the edge of a plasma sphere, with the plasma itself formed as a result of laser-driven compression and relaxation of a surrogate plastic-foam ball target. Three x-ray diagnostics, namely, 1D spatially resolved self-emission streaked imaging, 2D self-emission framed imaging, and backlighting radiography, have shown good agreement with the predicted evolution of the DS and its stability to low Legendre mode perturbations introduced by laser irradiation and target asymmetries.

Intraspecific wing venation and phallosome taxonomy updates in species of Loneura Navs (Psocodea, Ptiloneuridae), with one new species from cave and key to Loneura species from Brazil.

cavernicola sp. nov. is here described and illustrated, based on male and female specimens collected in caves located in an ecotone region between the Brazilian Savannah (Cerrado biome) and the Atlantic Forest, in Minas Gerais state, southeastern Brazil. Illustrations are provided of 19 types of variation in the fore and hindwings veins of males and females. Illustrations are presented of the holotype of L. maracaensis Garca Aldrete, along with illustrations of 18 types of variation in the fore and hindwing veins of males and females. Additionally, a new methodology applied in some specimens of L. maracaensis to process the genital pieces allowed us to know the arrangement and delimitations of each of the sclerites and their possible position during copulation. We therefore propose a phallosome taxonomic update. In these everted male genitalia, the spermatic sac and attached glands were identified for the first time. An identification key is presented to the Brazilian species of Loneura, based on males.

The genus Ptiloneura (Psocodea: Ptiloneuridae) in Valle del Cauca, Colombia, altitudinal distribution, new records, and description of two species.

From recent collections of psocids in natural areas of Valle del Cauca, Colombia, new records and two new species of the genus Ptiloneura were found. The latter are described and illustrated: P. elduende n. sp., and P. pichindensis n. sp., that correspond to a subclade previously named as genus Loneuroides. A map with the geographical and altitudinal distribution of the species in the department of Valle del Cauca, and a key for the determination of the species (males) in this subclade are presented.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment.

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Late-onset and long-lasting immune-related adverse events from immune checkpoint-inhibitors: An overlooked aspect in immunotherapy.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have revolutionised cancer therapy but frequently cause immune-related adverse events (irAEs). Description of late-onset and duration of irAEs in the literature is often incomplete. METHODS: To investigate reporting and incidence of late-onset and long-lasting irAEs, we reviewed all registration trials leading to ICI's approval by the US FDA and/or EMA up to December 2019. We analysed real-world data from all lung cancer (LC) and melanoma (Mel) patients treated with approved ICIs at the University Hospital of Lausanne (CHUV) from 2011 to 2019. To account for the immortal time bias, we used a time-dependent analysis to assess the potential association between irAEs and overall survival (OS). RESULTS: Duration of irAEs and proportion of patients with ongoing toxicities at data cut-off were not specified in 56/62 (90%) publications of ICIs registration trials. In our real-world analysis, including 437 patients (217 LC, 220 Mel), 229 (52.4%) experienced at least one grade ≥2 toxicity, for a total of 318 reported irAEs, of which 112 (35.2%) were long-lasting (≥6 months) and about 40% were ongoing at a median follow-up of 369 days [194-695] or patient death. The cumulative probability of irAE onset from treatment initiation was 42.8%, 51.0% and 57.3% at 6, 12 and 24 months, respectively. The rate of ongoing toxicity from the time of first toxicity onset was 42.8%, 38.4% and 35.7% at 6, 12 and 24 months. Time-dependent analysis showed no significant association between the incidence of irAEs and OS in both cohorts (log Rank p = 0.67 and 0.19 for LC and Mel, respectively). CONCLUSIONS: Late-onset and long-lasting irAEs are underreported but common events during ICIs therapy. Time-dependent survival analysis is advocated to assess their impact on OS. Real-world evidence is warranted to fully capture and characterise late-onset and long-lasting irAEs in order to implement appropriate strategies for patient surveillance and follow-up.

New species of Triplocania Roesler (Psocodea: Psocoptera: Ptiloneuridae) from Colombia and Peru.

Based on a survey of species of the genus Triplocania (Psocodea: Psocoptera) in forests of natural areas of Colombia and Peru, 18 species (14 from Colombia and 4 from Peru) were found, 16 of which are new to science and two correspond to males of Colombian species originally described from females (T. matildae Gonzlez et al., 2017, and T. sarriae Gonzlez et al., 2017). The new species, here described and illustrated are: T. altamira n. sp., T. antioquensis n. sp., T. antisuyuensis n. sp., T. atratoensis n. sp., T. caguanensis n. sp., T. caquetensis n. sp., T. einsteini n. sp., T. fabridiazi n. sp., T. galileii n. sp., T. hawkingi n. sp., T. mancocapaci n. sp., T. molanoi n. sp., T. nerudai n. sp., T. roesleri n. sp., T. tahuantisuyuensis n. sp., and T. yupanquii n. sp. The number of species of Triplocania is now raised to 118. To date, the highest number of species are found in Colombia, Brazil and Peru, with 59, 34 and 9 species respectively. An updated identification key to the species of Triplocania (males) is included, as well as a classification of the species in the genus.

Foam-lined hohlraum, inertial confinement fusion experiments on the National Ignition Facility.

Experiments on the National Ignition Facility (NIF) to study hohlraums lined with a 20-mg/cc 400-µm-thick Ta_{2}O_{5} aerogel at full scale (hohlraum diameter = 6.72 mm) are reported. Driven with a 1.6-MJ, 450-TW laser pulse, the performance of the foam liner is diagnosed using implosion hot-spot symmetry measurements of the high-density carbon (HDC) capsule and measurement of inner beam propagation through a thin-wall 8-µm Au window in the hohlraum. Results show an improved capsule performance due to laser energy deposition further inside the hohlraum, leading to a modest increase in x-ray drive and reduced preheat due to changes in the x-ray spectrum when the foam liner is included. In addition, the outer cone bubble uniformity is improved, but the predicted improvement in inner beam propagation to improve symmetry control is not realized for this foam thickness and density.

Brasineura Silva-Neto amp; García Aldrete (Psocodea, 'Psocoptera', Ptiloneuridae): new species, new records and variation in the wing venations.

Two new species of Brasineura are described from Brazil based on male specimens: Brasineura calori sp. n. (Bahia: Brazil) and Brasineura morrense sp. n. (Bahia: Brazil). They differ from the other species in the genus, in which the males are known, by hypandrium and phallosome structures. New records and comments on variation in the fore- and hind- wing venation of B. troglophilica Silva-Neto García Aldrete and B. diamantina Silva-Neto García Aldrete are presented. The identification key to male Brasineura species is updated.

Terapia nasal de alto flujo en la insuficiencia respiratoria aguda hipoxémica por SARS-CoV-2 / High-flow nasal therapy in SARS-CoV-2 hypoxemic acute respiratory failure

En enero de 2020 una nueva neumonía viral fue descrita en Wuhan, China. En marzo de 2020, la OMS declaró la emergencia mundial categorizando la amenaza global como pandemia. El punto de mayor discusión es el manejo del soporte respiratorio en estos pacientes, el riesgo de infección cruzada por la generación de aerosoles. El SARS-CoV-2 se transmite de persona a persona, predominantemente por diseminación y contacto de gotas respiratorias. Expertos reconocidos definen que el SDRA por COVID-19 no se rige estrictamente por la definición clásica de Berlín. El paciente con COVID-19 que se encuentra ventilando espontáneamente está envuelto en un círculo vicioso donde la alteración del pulmón como intercambiador de gases genera un aumento del drive respiratorio, el cual conlleva a la P-SILI. No hay hallazgos específicos, las imágenes responden a una neumonía viral típica. Sociedades de Cuidados Intensivos, organizaciones, han publicado sus posturas frente a la utilización de la terapia nasal de alto-flujo (TNAF) durante la pandemia por SARS-CoV-2. La TNAF emerge como una alternativa para el abordaje de la IRAh con el objetivo de evitar la intubación orotraqueal. En ausencia de criterios para la intubación inmediata, a los pacientes que presentan SDRA se les puede ofrecer un ensayo de TNAF en salas especiales con monitoreo estricto. La TNAF podría ser utilizada como tratamiento de primera línea en la IRAh por COVID-19 y su combinación con la posición prona parece mejorar la oxigenación; aún no hay datos de sobrevida, disminución en la tasa de IOT o mortalidad hospitalaria

In January 2020, a new viral pneumonia was described in Wuhan, China. In March 2020 the WHO declared a world emergency categorizing the global threat as a pandemic. The point of greatest discussion is the management of respiratory support in these patients, the risk of cross infection due to the generation of aerosols. SARS-CoV-2 is transmitted from person to person, predominantly through the spread and contact of respiratory droplets. Recognized experts define that ARDS by COVID-19 is not strictly governed by the classic Berlin definition. The patient with COVID-19 who is spontaneously ventilating is involved in a vicious circle where the alteration of the lung as a gas exchanger generates an increase in respiratory drive, which leads to P-SILI. There are no specific findings, the images respond to a typical viral pneumonia. Intensive care societies and organizations have published their positions on the use of high-flow nasal therapy (HFNC) during the SARS-CoV-2 pandemic. HFNC emerges as an alternative for the approach to ARF with the aim of avoiding orotracheal intubation. In the absence of criteria for immediate intubation, patients presenting with ARDS may be offered a TNAF assay in special rooms with close monitoring. HFNC could be used as a first-line treatment in ARF due to COVID-19 and its combination with the prone position seems to improve oxygenation, there is still no data on survival, decrease in the rate of EIT or hospital mortality

Diversity and vertical distribution of psocids (Psocodea: Psocoptera) in two forests of the Colombian Amazon / Diversidad y distribución vertical de psócidos (Psocodea: Psocoptera) en dos bosques de la Amazonía colombiana

Introduction: The knowledge on the diversity of psocids in Colombia has increased, following the global trend, but the main interest of most of the studies has been oriented to solve taxonomic aspects, leaving aside other biological aspects, of which little is known, such as the ecological interactions of these organisms in tropical forests. Objective: To describe the psocid diversity in two Colombian Amazonian localities and provide the first data on their vertical distribution in tropical forests. Methods: Monthly samplings of Psocoptera were conducted during new moon periods, from July 2014 to May 2015. Surveys were carried out in two localities of the Putumayo department, Colombia (Puerto Asís and Mocoa), using LED light traps. Results: During the sampling period, 152 species, in 23 genera and nine families were collected. The richest family was Psocidae, followed by Epipsocidae and Lachesillidae. More than 80 % of the species found are still undescribed, and among the described ones, nine represent new records for Colombia, and are shared with neighboring countries in the Amazon basin. Fourteen (9.2 %) species are shared by the two localities surveyed. Puerto Asís is considerably richer than Mocoa. Vertical stratification of Psocoptera was found in both localities, with the canopy being the most species rich stratum. Conclusion: The relatively high diversity of psocidos found, as well as the high number of new species, is an indicator of the need to continue the exploration of these organisms in the rest of the Colombian territory and Andean countries, especially in the Amazon foothills. Stratification of the studied psocoptera community was evident, with the canopy stratum being the richest in species, a trend that continues throughout the year.

Introducción: El conocimiento que se tiene acerca de la diversidad de psócidos en Colombia ha ido en aumento, siguiendo la tendencia mundial, pero el interés principal de la mayoría de estudios se ha centrado en la resolución de aspectos taxonómicos dejando de lado otros aspectos de su biología tales como las interacciones ecológicas de estos organismos en bosques tropicales. Objetivo: Describir la diversidad de psócidos en dos localidades de la Amazonía colombiana y proporcionar los primeros datos sobre su distribución vertical en bosques tropicales. Métodos: Se realizaron muestreos mensuales de psócidos durante los periodos de luna nueva entre julio 2014 y mayo 2015, en dos localidades del departamento de Putumayo, Colombia, utilizando trampas de luz LED. Resultados: Durante el periodo de muestreo, se recolectaron 152 especies, 23 géneros y nueve familias. La familia más rica en especies fue Psocidae, seguida por Epipsocidae y Lachesillidae. Más del 80 % de las especies encontradas no están descritas y entre las descritas, nueve representan nuevos registros para Colombia y son compartidas con países vecinos de la cuenca del Amazonas. Catorce especies (9.2 %) son compartidas por las dos localidades de este estudio; Puerto Asís presentó mayores valores de diversidad que Mocoa. En ambas localidades se encontró una estratificación en la distribución vertical de Psocoptera, siendo el dosel el estrato más rico en especies. Conclusión: La relativamente alta diversidad de psócidos encontrada, así como el alto número de especies nuevas, es un indicador de la necesidad de continuar las exploraciones de estos organismos en el resto del territorio colombiano y países andinos, especialmente en el piedemonte amazónico. Fue evidente una estratificación de la comunidad de psocópteros estudiada, siendo el estrato dosel el más rico en especies, una tendencia que se mantiene a lo largo del año.
