Published: October 2021

ABSTRACT

Introduction
A 6-week mindfulness training course, the Mind–Body Medicine (MBM) pilot program for staff, was implemented at a large military treatment facility to examine the preliminary efficacy of the program in reducing stress and burnout in military healthcare professionals.

Materials and Methods
A retrospective analysis was conducted of data collected from a single-arm prospective MBM pilot program. The program was designed to help staff members increase their awareness of burnout and its consequences and to learn how to utilize mindfulness-based self-care practices as a means for reducing stress and preventing burnout at work. Participants attended a 2-hour MBM group each week for a total duration of 6 weeks. Assessments of stress, resilience, anxiety, somatic symptoms, functional impairment, sleep quality, quality of life, and burnout were administered at baseline (T1), upon completion of the 6-week program (T2), and at least 3 months after program completion (T3). Multilevel modeling was used as the primary statistical model to assess changes in outcomes. Fifty-nine staff members completed assessments at T1, 31 (52.5%) at T2, and 17 (28.8%) at T3.

Results
Participants showed improvements on scores of perceived stress, resilience, anxiety, somatic symptoms, quality of life, and burnout variables from T1 to T2 and from T1 to T3 (P &lt; .05). Additionally, they reported improvements in their knowledge, understanding, and utilization of MBM concepts and practices from T1 to T2 and from T1 to T3 (P &lt; .05).

Conclusions
Results from this pilot suggest that the MBM program has the potential to reduce occupational stress and burnout and improve well-being in military healthcare professionals.

AbstractChromoblastomycosis is a chronic disease caused by melanized fungi that mainly affect individuals performing soil-related labor. The objective of this study was to analyze the epidemiological and clinical characteristics of chromoblastomycosis in Latin America and the Caribbean by an extensive literature review. An integrative review was performed of English, French, Portuguese, and Spanish publications in LILACS, SciELO, PubMed, SCOPUS and Web of Science databases covering the period 1969–2019. A total of 1211 articles were identified, of which 132 were included in the review, covering 2081 patients, 80.3% were males, the mean age was 56.1 years. The mean duration of the disease was 10.8 years. The lesions were mainly described in the lower limbs (60%). The most frequent clinical forms were verrucous (46.4%) and tumorous (21.7%). Major disease symptoms and signs consisted of itching and pain. Bacterial infection and functional limitation were important complications. Immunosuppression post-kidney transplantation was the most frequent comorbidity while leprosy was the main concomitant infectious disease. Fonsecaea pedrosoi and Cladophialophora carrionii were the predominant etiological agents. Majority of the cured cases were treated with itraconazole as monotherapy or in combination with other antifungals, surgery or cryosurgery. Chromoblastomycosis affects hundreds of rural workers in Latin America and the Caribbean, causing disability and personal, family and economic losses. It is important to prioritize epidemiological surveillance and early diagnosis of this disease in order to reveal its real prevalence and direct resources to preventive actions, diagnosis and early treatment.Lay summaryChromoblastomycosis is a slowly progressing chronic disease caused by melanized fungi. We collected data from South America and the Caribbean covering 1969–2019, the 132 articles included 2081 patients, mean disease duration was 10.8 years. Fonsecaea pedrosoi and Cladophialophora carrionii predominated.

ABSTRACT
The detection of 6Li in Spite plateau stars contradicts the standard big bang nucleosynthesis prediction, known as the second cosmological lithium problem. We measure the isotopic ratio 6Li/7Li in three Spite plateau stars: HD 84937, HD 140283, and LP 815−43. We use 3D non-local thermodynamic equilibrium radiative transfer and for the first time apply this to high-resolution, high signal-to-noise ratio data from the ultra-stable ESPRESSO/Very Large Telescope spectrograph. These are among the best spectra ever taken of any metal-poor stars. As the measurement of 6Li/7Li is degenerate with other physical stellar parameters, we employ Markov chain Monte Carlo methods to find the probability distributions of measured parameters. As a test of systematics, we also use three different fitting methods. We do not detect 6Li in any of the three stars, and find consistent results between our different methods. We estimate 2σ upper limits to 6Li/7Li of 0.7, 0.6, and 1.7 per cent, respectively, for HD 84937, HD 140283, and LP 815−43. Our results indicate that there is no second cosmological lithium problem, as there is no evidence of 6Li in Spite plateau stars.

ABSTRACT
Up to now, WASP-12b is the only hot Jupiter confirmed to have a decaying orbit. The case of WASP-43b is still under debate. Recent studies preferred or ruled out the orbital decay scenario, but further precise transit timing observations are needed to definitively confirm or refute the period change of WASP-43b. This possibility is given by the Transiting Exoplanet Survey Satellite (TESS) space telescope. In this work, we used the available TESS data, multicolour photometry data obtained with the Multicolor Simultaneous Camera for studying Atmospheres of Transiting exoplanets 2 (MuSCAT2) and literature data to calculate the period change rate of WASP-43b and to improve its precision, and to refine the parameters of the WASP-43 planetary system. Based on the observed-minus-calculated data of 129 mid-transit times in total, covering a time baseline of about 10 yr, we obtained an improved period change rate of $\dot{P} = -0.6 \pm 1.2$ ms yr−1 that is consistent with a constant period well within 1σ. We conclude that new TESS and MuSCAT2 observations confirm no detection of WASP-43b orbital decay.
3D MHD simulations of the supernova remnant CTB 109

Published: October 2021

ABSTRACT
We examine the evolution and emission of the supernova remnant (SNR) CTB 109 using 3D magnetohydrodynamics simulations. The SNR evolves in a medium divided by a plane interface into two media with different densities and pressure equilibrium. Our results reveal that a remnant with the characteristics of CTB 109 is formed provided the supernova (SN) explosion takes place in the less dense medium and also if the interstellar magnetic field (ISMF) is almost uniform. Finally, we conclude that the quasi-parallel mechanism can explain the brightness synchrotron emission and the position angle of the projected ISMF reported in previous works.
Eclipse timing variation analysis of OGLE-IV eclipsing binaries towards the Galactic Bulge – II. Short periodic triple stellar systems

Published: October 2021

ABSTRACT
We report an eclipse timing variations (ETV) study to identify close, stellar mass companions to the eclipsing binaries monitored during the photometric survey Optical Gravitational Lensing Experiment-IV. We also present an alternative automatic way to determine the first and last contacts of an eclipse. Applying the phase dispersion minimization method to identify potential triples, we find close third components with outer periods in less than 1500 d in 23 systems. We present outer orbit solution for 21 of 23 systems. For the 10 tightest triples, we find that the ETV can only be modelled with the combination of the light-travel-time effect (LTTE) and third-body perturbations, while in case of another 11 systems, pure LTTE solutions are found to be satisfactory. In the remaining two systems, we identify extra eclipses connected to the outer component, but for the incomplete and noisy ETV curves, we are unable to find realistic three-body solutions. Therefore, in these cases we give only the outer period.

ABSTRACT
We present the first characterization of the circumgalactic medium of Ly α emitters (LAEs), using a sample of 96 z ≈ 3.3 LAEs detected with the VLT/MUSE in fields centred on eight bright background quasars. The LAEs have low Ly α luminosities ($\sim 10^{42}\, \text{erg}\, \text{s}^{-1}$) and star formation rates (SFRs) $\sim 1~\text{M}_\odot \, \text{yr}^{-1}$, which for main-sequence galaxies correspond to stellar masses of only $\sim 10^{8.6}\, \text{M}_\odot$. The median transverse distance between the LAEs and the quasar sightlines is 165 proper kpc (pkpc). We stacked the high-resolution quasar spectra and measured significant excess H i and C iv absorption near the LAEs out to 500 $\text{km}\, \text{s}^{-1}$ and at least ≈250 pkpc (corresponding to ≈7 virial radii). At $\lesssim 30~\text{km}\, \text{s}^{-1}$ from the galaxies, the median H i and C iv optical depths are enhanced by an order of magnitude. The absorption is significantly stronger around the ≈1/3 of our LAEs that are part of ‘groups’, which we attribute to the large-scale structures in which they are embedded. We do not detect any strong dependence of either the H i or C iv absorption on transverse distance (over the range ≈50–250 pkpc), redshift, or the properties of the Ly α emission line (luminosity, full width at half-maximum, or equivalent width). However, for H i, but not C iv, the absorption at $\lesssim 100\, \text{km}\, \text{s}^{-1}$ from the LAE does increase with the SFR. This suggests that LAEs surrounded by more H i tend to have higher SFRs.

Abstract
Evidence accumulated in recent years has revealed that neutrophils are involved in the initial establishment of endometriosis, which is well-known as a chronic inflammatory disease. So far, why and how neutrophils promote the formation of early endometriosis are still unclear. In this study, using a mouse model of endometriosis, we demonstrated that endometriosis mice (EMs mice) had a significantly increased number of neutrophils in peritoneal fluids and lesions, and increased levels of granulocyte colony-stimulating factor (G-CSF) and IL-6 in serum and peritoneal fluids compared to the control group. In the neutrophils and uterine fragments co-injection experiment, neutrophils regulated by G-CSF and IL-6 had a similar effect to neutrophils from EMs mice, increasing the number, area, weight and microvessel density (MVD) of endometriotic lesions. Blocking the effect of G-CSF and IL-6 in EMs mice resulted in a decrease in the number, area and weight of endometriotic lesions. Following the depletion of neutrophils in vivo using a anti-Ly6G antibody, the MVD in the lesions of mice treated with neutrophils from EMs mice and neutrophils from pG/pI6 mice were significantly reduced. Neutrophils from EMs mice and neutrophils from pG/pI6 mice altered the expression levels of Mmp9, Bv8 and Trail genes compared to the neutrophils from PBS-treated mice. IL-6 together with G-CSF induced a higher expression of phospho-STAT3 and STAT3 in neutrophils. These findings suggest that neutrophils modulated by G-CSF and IL-6 through the STAT3 pathway alter the expression levels of the angiogenesis-related genes Mmp9, Bv8 and Trail, and may promote the establishment of early endometriosis.
COVID-19 survivors with calcineurin-inhibitors-treated rheumatoid arthritis

Published: October 2021

ABSTRACT
We report two cases recovered from coronavirus disease 2019 with rheumatoid arthritis which had been in remission or low disease activity by taking calcineurin inhibitor (CNI). Both cases had moderate to severe pneumonia treated with intravenous dexamethasone or in the severe case remdesivir in addition to it. These cases suggest that the use of CNI may have affected the improvement of severe pneumonia.
Retrograde Suction Decompression for Clipping of a Giant Ophthalmic Internal Carotid Artery Aneurysm: 2-Dimensional Operative Video

Published: October 2021

Abstract
Microsurgical clipping of large paraclinoid aneurysms is challenging because of the complex anatomy of the dural rings, lack of easy proximal control, and wide aneurysm necks. Proximal retrograde suction decompression, or the Dallas technique, can reduce aneurysm turgor and, with aspiration of the trapped cervical and supraclinoid internal carotid arteries (ICAs), can collapse the aneurysm to aid microsurgical clipping.
1-5

A woman in her late 30s presented with decreased right-eye visual acuity. Informed written consent was obtained for microsurgical management and publication. Upon cervical exposure of the carotid bifurcation, we performed a standard pterional craniotomy, trans-sylvian exposure, and intradural anterior clinoidectomy. After burst suppression and cross-clamping of the carotid, we inserted an angiocatheter at the common carotid artery (CCA). Distal temporary clips were placed on the posterior communicating artery and C7 ICA. With the cervical ICA unclamped, retrograde suction was continuously applied to deflate the aneurysm. We applied 2 pairs of fenestrated-booster clips to the aneurysm dome and a fifth clip to the aneurysm neck. After restoration of flow, indocyanine green angiography and Doppler assessments were performed. The proximal clip was converted into a curved clip to optimize ICA flow.
Postoperative angiography confirmed complete occlusion of the aneurysm. The patient was discharged on postoperative day 3, with stable visual acuity.

This video demonstrates that retrograde suction decompression via the cervical CCA can be safely performed to facilitate clipping of complex paraclinoid ICA aneurysms. Comprehensive planning of temporary aneurysm trapping for suction decompression and permanent clip construct for aneurysm occlusion are needed for effective aneurysm repair.

Abstract Conditioned pain modulation (CPM) can discriminate between healthy and chronic pain patients. However, its relationship with neurophysiological pain mechanisms is poorly understood. Brain oscillations measured by electroencephalography (EEG) might help gain insight into this complex relationship.ObjectiveTo investigate the relationship between CPM response and self-reported pain intensity in non-specific chronic low back pain (NSCLBP) and explore respective EEG signatures associated to these mechanisms.DesignCross-sectional analysis.ParticipantsThirty NSCLBP patients participated.MethodsSelf-reported low back pain, questionnaires, mood scales, CPM (static and dynamic quantitative sensory tests), and resting surface EEG data were collected and analyzed. Linear regression models were used for statistical analysis.ResultsCPM was not significantly correlated with self-reported pain intensity scores. Relative power of EEG in the beta and high beta bands as recorded from the frontal, central, and parietal cortical areas were significantly associated with CPM. EEG relative power at delta and theta bands as recorded from the central area were significantly correlated with self-reported pain intensity scores while controlling for self-reported depression.ConclusionsFaster EEG frequencies recorded from pain perception areas may provide a signature of a potential cortical compensation caused by chronic pain states. Slower EEG frequencies may have a critical role in abnormal pain processing.

Authors: Valera-Calero Juan Antonio , Úbeda-D'Ocasar Edurne , Caballero-Corella Mario , Fernández-de-las-Peñas César , Sendarrubias Gracia María Gallego , Arias-Buría José Luis 
Published: October 2021

Abstract

Objective
Some studies have reported the presence of histological alterations, such as myofiber disorganization and abnormalities in the number and shape of mitochondria, in patients with fibromyalgia syndrome (FMS). Although Ultrasound imaging (US) is used to quantitatively characterize muscle tissues, US studies in patients with FMS are lacking. Therefore, we aimed to describe morphological and qualitative cervical multifidus (CM) muscle US features in women with FMS and to assess their correlation with clinical indicators.

Design
Observational study.

Setting
AFINSYFACRO Fibromyalgia Association (Madrid, Spain).

Subjects
Forty-five women with FMS participated.

Methods
Sociodemographic variables (e.g., age, height, weight, body mass index) and clinical outcomes (e.g., pain as assessed on a numerical pain rating scale, evolution time, pain-related disability as assessed by the Fibromyalgia Impact Questionnaire) were collected. Images were acquired bilaterally at the cervical spine (C4–C5 level) and measured by an experienced examiner for assessment of muscle morphology (e.g., cross-sectional area, perimeter, and shape) and quality (mean echo intensity and intramuscular fatty infiltration). Side-to-side comparisons and a correlational analysis were conducted.

Results
No significant side-to-side differences were found for morphology or quality features (P &gt; 0.05). None of the clinical indicators were associated with US characteristics (all, P &gt; 0.05).

Conclusion
Our results showed no side-to-side differences for CM morphology and quality as assessed with US. No associations between CM muscle morphology or quality and Fibromyalgia Impact Questionnaire, pressure pain threshold, numerical pain rating scale score, or evolution time were observed. Our preliminary data suggest that muscle morphology is not directly related to pain and pain-related disability in women with FMS.
A strategy for school reopening in the Philippines: Lessons from other countries
Authors: Maboloc Christopher Ryan 
Published: October 2021

Abstract
The Philippine government has not announced a strategy for a safe return to in-person instruction. A gradual approach, beginning in low-risk areas, at 50% capacity for every classroom, with students divided into two groups and alternating between in-person and online instruction every 2 weeks, is proposed. A safe return to in-person instruction in schools for millions of students in the Philippines is consistent with the concept of equity in education.
Policy Effects of International Taxation on Firm Dynamics and Capital Structure
Authors: Spencer Adam Hal 
Published: October 2021

Abstract
This article develops a quantitative open economy framework with dynamics, firm heterogeneity and financial frictions to study the impact of corporate tax reforms targeted at multinationals. The model quantifies their impact on firm selection, production and welfare. Firms draw idiosyncratic shocks, invest in capital, choose optimal financing and select endogenously into selling abroad, through exporting or FDI. I apply this framework to the removal of the U.S. repatriation tax as in the Tax Cuts and Jobs Act. The reform’s impact trades-off two selection effects—more offshoring versus greater U.S. business dynamism. The reform leads to higher U.S. welfare at little cost to the Treasury. A series of exercises illustrate that the novel features of this framework have significant quantitative implications. The reform gives starkly different cross-sectional predictions and lower welfare gains when financial frictions are removed and it is welfare reducing in a static counterpart of the model.

Published: October 2021

Abstract
The aim of the present study was to estimate the volume CT dose index (CTDIvol), dose length product (DLP) and effective dose (ED) to patients from five multi-detector computed tomography angiography (MDCTA) procedures: brain, carotid, coronary, entire aorta and lower limb from four medical institutions in Tanzania; to compare these doses to those reported in the literature, and to compare the data obtained with ICRP 103 and Monte Carlo software. The radiation doses for 217 patients were estimated using patient demographics, patient-related exposure parameters, the geometry of examination and CT-Expo V 2.4 Monte Carlo-based software. The median values of the CTDIvol, DLP and ED for MDCTA procedures of the brain and carotids were 36.8 mGy, 1481.0 mGy∙cm and 5.2 mSv, and 15.9 mGy, 1224.0 mGy∙cm and 7.8 mSv, respectively; while for the coronary, entire aortic, and lower limbs were 49.4 mGy, 1493.0 mGy∙cm and 30.6 mSv; 16.2 mGy, 2287.0 mGy∙cm and 41.1 mSv; and 6.4 mGy, 1406.0 mGy∙cm and 10.5 mSv, respectively. The ratio of the maximum to minimum ED values to individual patients across the four medical centers were 41.4, 11.1, 4.6, 9.5 and 37.4, respectively, for the brain, carotid, coronary, entire aortic and lower limb CT angiography procedures. The mean values of CTDIvol, DLP and ED in the present study were typically higher than the values reported from Kenya, Korea and Saudi Arabia. The 75th percentile values of the DLP were above the preliminary diagnostic references levels proposed by Kenya, Switzerland and Korea. The observed wide range of examination scanning protocols and patient doses for similar MDCTA procedures within and across hospitals; and the observed relatively high patient doses compared to those reported in the literature, call for the need to standardize scanning protocols and optimise patient dose from MDCTA procedures.
