The effects of non-linearities on tidal flows in the convective envelopes of rotating stars and planets in exoplanetary systems
Authors: Astoul A , Barker A J 
Published: July 2022

ABSTRACT
In close exoplanetary systems, tidal interactions drive orbital and spin evolution of planets and stars over long time-scales. Tidally forced inertial waves (restored by the Coriolis acceleration) in the convective envelopes of low-mass stars and giant gaseous planets contribute greatly to the tidal dissipation when they are excited and subsequently damped (e.g. through viscous friction), especially early in the life of a system. These waves are known to be subject to non-linear effects, including triggering differential rotation in the form of zonal flows. In this study, we use a realistic tidal body forcing to excite inertial waves through the residual action of the equilibrium tide in the momentum equation for the waves. By performing 3D non-linear hydrodynamical simulations in adiabatic and incompressible convective shells, we investigate how the addition of non-linear terms affects the tidal flow properties, and the energy and angular momentum redistribution. In particular, we identify and justify the removal of terms responsible for unphysical angular momentum evolution observed in a previous numerical study. Within our new set-up, we observe the establishment of strong cylindrically sheared zonal flows, which modify the tidal dissipation rates from prior linear theoretical predictions. We demonstrate that the effects of this differential rotation on the waves neatly explains the discrepancies between linear and non-linear dissipation rates in many of our simulations. We also highlight the major role of both corotation resonances and parametric instabilities of inertial waves, which are observed for sufficiently high tidal forcing amplitudes or low viscosities, in affecting the tidal flow response.

ABSTRACT
The gamma-ray emission from Starburst and Star-forming Galaxies (SBGs and SFGs) strongly suggests a correlation between star-forming activity and gamma-ray luminosity. However, the very nature of cosmic ray (CR) transport and the degree of their confinement within SBG cores are still open questions . We aim at probing the imprints left by CR transport on gamma-ray and neutrino observations of point-like SFGs and SBGs, looking into quantitative ways to discriminate among different transport models. We analyse the 10-yr Fermi-LAT spectral energy distributions of 13 nearby galaxies with two different CR transport models, taking into account the corresponding IR and UV observations. We also generate mock gamma-ray data to simulate the CTA performance in detecting these sources. In this way, we propose a test to discriminate between the two CR models, quantifying the statistical confidence at which one model can be preferred over the other. We point out that the current data already give a slight preference to CR models that are dominated by advection. Moreover, we show that CTA will allow us to firmly disfavour models dominated by diffusion over self-induced turbulence, compared to advection-dominated models, with Bayes factors, which can be as large as 107 for some of the SBGs. Finally, we estimate the diffuse gamma-ray and neutrino fluxes of SFGs and SBGs, showing that they can explain $25{{\,\rm per\ cent}}$ of the diffuse HESE data while remaining consistent with gamma-ray limits on non-blazar sources.
Onset of common envelope evolution during a core helium flash by rapid envelope expansion
Authors: Fainer Stanislav , Bear Ealeal , Soker Noam 
Published: July 2022

ABSTRACT
We suggest that the vigorous core convection during core helium flash on the tip of the red giant branch (RGB) of low-mass stars excites waves that carry energy to the envelope and inflate it for few years to increase the number of extreme horizontal branch (EHB; sdB and sdO) stars with masses of $\simeq 0.47 \, \mathrm{M}_\odot$ with respect to canonical binary evolution. Using the open-source mesa-binary, we follow the evolution of a number of eccentric binary systems with an initial primary stellar mass of $1.6 \, \mathrm{M}_\odot$. The energy that the waves carry to the envelope leads to envelope expansion at the tip of the RGB. The inflated RGB star engulfs many secondary stars to start a CEE that otherwise would not occur. If the secondary star manages to remove most of the RGB envelope the primary evolves to become an EHB star with a mass of $\simeq 0.47 \, \mathrm{M}_\odot$. However, we expect that in most cases the secondary star does not have time to spiral-in to close orbits. It rather ends at a large orbit and leaves a massive enough envelope for the primary star to later evolve along the asymptotic giant branch and to engulf the secondary star, therefore forming a non-spherical planetary nebula.

ABSTRACTWe investigate using three-point statistics in constraining the galaxy–halo connection. We show that for some galaxy samples, the constraints on the halo occupation distribution parameters are dominated by the three-point function signal (over its two-point counterpart). We demonstrate this on mock catalogues corresponding to the Luminous red galaxies (LRGs), Emission-line galaxies (ELGs), and quasars (QSOs) targeted by the Dark Energy Spectroscopic Instrument (DESI) Survey. The projected three-point function for triangle sides less up to 20 h−1 Mpc measured from a cubic Gpc of data can constrain the characteristic minimum mass of the LRGs with a preci sion of 0.46 per cent. For comparison, similar constraints from the projected two-point function are 1.55 per cent. The improvements for the ELGs and QSOs targets are more modest. In the case of the QSOs, it is caused by the high shot-noise of the sample, and in the case of the ELGs, it is caused by the range of halo masses of the host haloes. The most time-consuming part of our pipeline is the measurement of the three-point functions. We adopt a tabulation method, proposed in earlier works for the two-point function, to significantly reduce the required compute time for the three-point analysis.

Published: July 2022

ABSTRACT
New spectrometric (HERCULES) and ground-based multicolour photometric data on the multiple star V410 Puppis are combined with satellite photometry (HIPPARCOS and TESS), as well as historic astrometric observations. Absolute parameters for V410 Pup Aab are derived: MAa = 3.15 ± 0.10, MAb = 1.83 ± 0.08 (M⊙); RAa = 2.12 ± 0.10, RAb = 1.52 ± 0.08 (R⊙); a = 6.57 ± 0.04 R⊙; TAa = 12500 ± 1000, TAb = 9070 ± 800(K), and photometric distance 350 ± 10 (pc). We report the discovery of a low-amplitude SPB variation in the light curve and also indications of an accretion structure around V410 Pup B as well as emission cores in V410 Pup C. We argue that V410 Pup is probably a young formation connected with the Vela 2 OB Association. The combined evidence allows an age in the range 7–25 Myr from comparisons with standard stellar evolution modelling.

Abstract

Objective
The purpose of this study was to determine the acute effect of an abdominal hypopressive exercise (AHE) on linea alba morphology among women who are primiparous and to compare this effect with that of other common abdominal exercise modalities.

Methods
A cross-sectional study of 46 women 3 months after first delivery was conducted. B-mode ultrasound imaging of the interrectus distance (IRD) and linea alba distortion was performed 2 cm below (I-point) and above (S-point) the umbilicus and at the mid-point between the umbilicus and xiphoid process (X-point). Images were recorded at rest and during an AHE performed in a supine position, a semi curl-up (SCU), an abdominal drawing-in maneuver (ADIM), and a SCU performed after an initial ADIM (ADIM+SCU).

Results
The SCU exercise narrowed the IRD at the X- and S-points. Compared with SCU, AHE and ADIM widened the IRD at the S- and X-points. No significant differences were found when comparing the IRD at rest, during AHE and during ADIM, but AHE tended to narrow I-point IRD more than ADIM but to widen S-point IRD more than ADIM+SCU. No participant showed linea alba distortion during the AHE or ADIM. When compared, SCU increased the occurrence of distortion with respect to AHE and ADIM. The isolated hypopressive posture did not change the IRD or linea alba distortion.

Conclusion
Among women who were postpartum, AHE seemed to narrow IRD below the umbilicus compared with ADIM without either of these 2 modalities generating linea alba distortion, as SCU or ADIM+SCU does. Thus, although no significant differences were found when comparing the IRD at rest and during AHE, the AHE could improve the tensile response of the linea alba without increasing the IRD.

Impact
This is believed to be the first study to describe linea alba changes during AHE in women who are postpartum. AHE and ADIM seem to show different effects on infraumbilical IRD. The lack of distortion suggests that linea alba may undergo tensile loading at all levels.
Leveraging genetic discoveries for sleep to determine causal relationships with common complex traits

Published: July 2022

Abstract
Sleep occurs universally and is a biological necessity for human functioning. The consequences of diminished sleep quality impact physical and physiological systems such as neurological, cardiovascular, and metabolic processes. In fact, people impacted by common complex diseases experience a wide range of sleep disturbances. It is challenging to uncover the underlying molecular mechanisms responsible for decreased sleep quality in many disease systems owing to the lack of suitable sleep biomarkers. However, the discovery of a genetic component to sleep patterns has opened a new opportunity to examine and understand the involvement of sleep in many disease states. It is now possible to use major genomic resources and technologies to uncover genetic contributions to many common diseases. Large scale prospective studies such as the genome wide association studies (GWAS) have successfully revealed many robust genetic signals associated with sleep-related traits. With the discovery of these genetic variants, a major objective of the community has been to investigate whether sleep-related traits are associated with disease pathogenesis and other health complications. Mendelian Randomization (MR) represents an analytical method that leverages genetic loci as proxy indicators to establish causal effect between sleep traits and disease outcomes. Given such variants are randomly inherited at birth, confounding bias is eliminated with MR analysis, thus demonstrating evidence of causal relationships that can be used for drug development and to prioritize clinical trials. In this review, we outline the results of MR analyses performed to date on sleep traits in relation to a multitude of common complex diseases.

Study Design.
Retrospective cohort analysis.

Objective.
To investigate the safety profile of outpatient versus inpatient single-level and multiple-level cervical disk replacement (CDR) by analyzing one- and two-year surgical outcomes and 90-day medical complications using a large patient database.

Summary of Background Data.
CDR is becoming a more desirable option for patients undergoing cervical spine procedures. Unlike anterior cervical diskectomy and fusion, CDR is motion-preserving and has been shown to reduce rates of adjacent segment disease. Current literature investigating outpatient versus inpatient CDR has shown a similar safety profile among the two cohorts. However, most of these studies have relatively small sample sizes with short-term follow-up.

Materials and Methods.
A retrospective cohort study was done using the PearlDiver patient database between 2010 and 2019. Patients who underwent single-level and multiple-level CDR with a follow-up of at least two years were identified. Patients within each procedure cohort were subdivided into an outpatient and an inpatient group. Univariate and multivariable analyses were performed.

Results.
In total, 2294 patients underwent single-level CDR of which 506 patients underwent outpatient CDR and 1788 underwent inpatient CDR. In total, 236 patients underwent multiple-level CDR of which 49 patients underwent outpatient CDR and 187 underwent inpatient CDR. In the single-level CDR cohort, patients undergoing outpatient CDR were found to have lesser odds of a decompressive laminectomy at one year following the initial procedure (odds ratio=0.471; 95% confidence interval: 0.205–0.945; P=0.05). No significant differences in one- and two-year surgical complications, or 90-day postoperative complications, were found on multivariate analysis of outpatient versus inpatient multiple-level CDR.

Conclusion.
Our study found that performing single-level and multiple-level CDR on an outpatient basis has a similar safety profile to patients who underwent these procedures in an inpatient setting.

Published: July 2022

OBJECTIVES:
This study sought to identify monocyte alterations from septic patients after hospital discharge by evaluating gene expression of inflammatory mediators and monocyte polarization markers. It was hypothesized that sepsis reprograms the inflammatory state of monocytes, causing effects that persist after hospital discharge and influencing patient outcomes.

DESIGN:
The gene expression patterns of inflammatory receptors, M1 and M2 macrophage polarization markers, NLRP3 inflammasome components, and pro- and anti-inflammatory cytokines in monocytes were assessed.

PATIENTS:
Thirty-four patients from the University of São Paulo Hospital, during the acute sepsis phase (phase A), immediately after ICU discharge (phase B), and 3 months (phase C), 6 months (phase D), 1 year (phase E), and 3 years (phase F) after discharge, were included. Patients that died during phases A and B were grouped separately, and the remaining patients were collectively termed the survivor group.

MEASUREMENTS AND MAIN RESULTS:
The gene expression of toll-like receptor (TLR)2 and TLR4 (inflammatory receptors), NLRP3, NFκB1, adaptor molecule apoptosis-associated speck-like protein containing a CARD, caspase 1, caspase 11, and caspase 12 (NLRP3 inflammasome components), interleukin-1α, interleukin-1β, interleukin-18, and high-mobility group box 1 protein (proinflammatory cytokines), interleukin-10 (anti-inflammatory cytokine), C-X-C motif chemokine ligand 10, C-X-C motif chemokine ligand 11, and interleukin-12p35 (M1 inflammatory polarization markers), and C-C motif chemokine ligand 14, C-C motif chemokine ligand 22, transforming growth factor-beta (TGF-β), SR-B1, and peroxisome proliferator-activated receptor γ (M2 anti-inflammatory polarization and tissue repair markers) was upregulated in monocytes from phase A until phase E compared with the control group.

CONCLUSIONS:
Sepsis reprograms the inflammatory state of monocytes, probably contributing to postsepsis syndrome development and mortality.

Published: July 2022

OBJECTIVES:
Optimal time for ICU diary delivery and impact on mental health (MH), anxiety-depression, post-traumatic stress symptoms (PTSS), quality of life (QOL), and memories is unclear. We evaluated the effect of ICU diaries, dispatched at different time points, on outcomes in an Indian cohort.

DESIGN:
Double-blind randomized controlled trial.

SETTING:
A 1,000-bedded teaching hospital in East India.

PATIENTS:
Mechanically ventilated (>24 hr) adults were recruited, excluding those dead or incapable of meaningful-communication at discharge or follow-up. Eighty-three patients, aged 46.2 ± 17.2 years, Acute Physiology and Chronic Health Evaluation II scores 13.7 ± 4.9 were assessed. Length of ICU stay was 8.2 ± 7.1 days with 3.7 ± 3.2 ventilator days.

INTERVENTION:
Of 820 screened, 164 had diaries created. Including photographs, diaries were comaintained by healthcare workers and family members. Ninety patients were randomized at 1-month follow-up: diary sent to 45 at 1 month (group ID1) and to 45 at 3 months (ID3).

MEASUREMENTS AND MAIN RESULTS:
Anxiety-depression, memory, and QOL were assessed telephonically or home visits by a psychologist using the Hospital Anxiety-Depression Scale (HADS) and other tools at ICU discharge, 1-month (prerandomization), and 3 months of discharge. ID3 was reassessed after receiving diaries at 3.5 months. Primary outcome was anxiety-depression; secondary outcomes included PTSS, QOL, and memories. There was 100% follow-up. At 3 months, ID1 patients had a significant (p < 0.001) reduction in HADS from baseline when compared with ID3 that had not received diaries (4.16 ± 2.9 vs 2.15 ± 1.8; 95% CI, 2.8–1.2). PTSS scores were likewise better (p < 0.001). ID3 patients demonstrated significant improvement (p < 0.01) in QOL and memories along with HADS and PTSS when assessed at 3.5 months.

CONCLUSIONS:
ICU diaries improve MH but not QOL when delivered at 1 month and assessed 2 months thereafter. Assessed after 15 days, delayed exposure at 3 months significantly improved QOL and memories in addition to MH.

Published: July 2022

Background
In a public health emergency, the psychological stress of nursing staff should be assessed, and nurses who cared for coronavirus disease 2019 (COVID-19) patients were constantly under pressure. Currently, frontline health care workers are experiencing mental health issues. The personal quality of life is directly related to the working environment, especially at this moment, when nursing could be a highly stressful and emotionally draining job.

Objectives
During the COVID-19 pandemic, the primary objectives of the study were to describe the quality of life, posttraumatic stress disorder, and self-efficacy and to identify any associated factors of pediatric critical care nurses. This study is a multicenter cross-sectional study.

Methods
Data were collected between February and May 2021 from pediatric critical care nurses. The following instruments were used: the Nursing Quality of Life Scale, the Nursing Profession Self-Efficacy Scale, and the Impact of Event Scale.

Results
One hundred twelve nurses participated in this study with a 40% of response rate. Data suggest a better global perception of quality of life by male subjects (F = 6.65, P = .011). The nurses who cared for COVID-19 patients reported a lower quality of social life (F = 4.09, P = .045); furthermore, the nurses who had clinically vulnerable people in their families reported a worse quality of physical life (F = 4.37, P = .045). Approximately 50% of nurses reported sleep disturbances, and 37% reported symptoms of posttraumatic stress disorder, especially female nurses (F = 8.55, P = .04).

Conclusion
According to this study, female nurses were more likely to experience posttraumatic stress disorder symptoms during the COVID-19 pandemic. Furthermore, findings also highlighted a lower quality of social life for those with clinically vulnerable relatives may be due to a self-limitation of interactions with other people. Finally, sleep disturbances were prevalent, potentially affecting nurses' mental health and performance.

Published: July 2022

Introduction
Patients discharged from the intensive care unit (ICU) suffer from long-term symptoms affecting the physical, psychological, and cognitive well-being and cannot understand memories and dreams. Intensive care unit diaries describe daily events about the patient and may allow them to reconstruct their experience.

Objective
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the effects of ICU diaries on posttraumatic stress disorder (PTSD), depression, and anxiety.

Methods
Five electronic databases were searched up to May 6, 2022. We included RCTs comparing patients admitted to the ICU who received a diary to those who did not receive a diary. The primary outcome was the rate of PTSD. Secondary outcomes were rates of depression and anxiety.

Results
We included 7 RCTs. Patients who received a diary during the ICU admission had reduced rate of PTSD (78/432 [18%] vs 106/422 [25%]; risk ratio [RR], 0.73; 95% confidence interval [CI], 0.57-0.94; P = .02; I
2 = 0%; trial sequential analysis-adjusted CI, 0.55-0.97) when compared with patients who did not receive a diary. We found a non–statistically significant difference toward a reduction in the rate of depression (38/232 [16%] vs 54/224 [24%]; RR, 0.70; 95% CI, 0.49-1.01; P = .06; I
2 = 0%) and anxiety (63/232 [27%] vs 70/224 [31%]; RR, 0.64; 95% CI, 0.29-1.40; P = .26; I
2 = 67%).

Conclusions
Providing an ICU diary to patients admitted to the ICU reduced the rate of PTSD symptoms compared with usual care.
