Association between Physical Activity and Postnatal Depression
Authors: Rafdi Abi 
Published: January 2022

Many changes could occur in a woman’s body, both mental and physical, during pregnancy and the postnatal period. The process of childbirth and a changing role as a new mom can be associated with many disturbances of emotions. Besides that, the development of baby blues or postpartum depression may occur in the puerperium period. Depression in post partum occurs in one month after childbirth and may be prolonged to one year. Depressive disorders in a young mother affect the mother and the newborn’s health status. That is why it is crucial to identify for factors that could significantly reduce the likelihood of developing depression in this period. The literature review was aimed at describing the relationship of physical activity during pregnancy and postpartum and the development of postnatal depression. It was shown that physical activity during pregnancy and puerperium, or in the postnatal period itself reduces the risk of developing depression in pregnancy and after delivery. Physical activity can be an essential factor in preventing depressive disorders in women in the postnatal period.

Abstract
Compact star-forming clumps observed in distant galaxies are often suggested to play a crucial role in galaxy assembly. In this paper, we use a novel approach of applying finite-resolution deconvolution on ground-based images of the COSMOS field to resolve 20,185 star-forming galaxies (SFGs) at 0.5 < z < 2 to an angular resolution of 0.″3 and study their clump fractions. A comparison between the deconvolved images and HST images across four different filters shows good agreement and validates image deconvolution. We model spectral energy distributions using the deconvolved 14-band images to provide resolved surface brightness and stellar-mass density maps for these galaxies. We find that the fraction of clumpy galaxies decreases with increasing stellar masses and with increasing redshift: from ∼30% at z ∼ 0.7 to ∼50% at z ∼ 1.7. Using abundance matching, we also trace the progenitors for galaxies at z ∼ 0.7 and measure the fractional mass contribution of clumps toward their total mass budget. Clumps are observed to have a higher fractional mass contribution toward galaxies at higher redshift: increasing from ∼1% at z ∼ 0.7 to ∼5% at z ∼ 1.7. Finally, the majority of clumpy SFGs have higher specific star formation rates (sSFR) compared to the average SFGs at fixed stellar mass. We discuss the implication of this result for in situ clump formation due to disk instability.

Abstract
The water snowline location in protostellar envelopes provides crucial information about the thermal structure and the mass accretion process as it can inform about the occurrence of recent (≲1000 yr) accretion bursts. In addition, the ability to image water emission makes these sources excellent laboratories to test indirect snowline tracers such as H13CO+. We study the water snowline in five protostellar envelopes in Perseus using a suite of molecular-line observations taken with the Atacama Large Millimeter/submillimeter Array (ALMA) at ∼0.″2−0.″7 (60–210 au) resolution. B1-c provides a textbook example of compact

(31,3−22,0) and HDO (31,2−22,1) emission surrounded by a ring of H13CO+ (J = 2−1) and HC18O+ (J = 3−2). Compact HDO surrounded by H13CO+ is also detected toward B1-bS. The optically thick main isotopologue HCO+ is not suited to trace the snowline, and HC18O+ is a better tracer than H13CO+ due to a lower contribution from the outer envelope. However, because a detailed analysis is needed to derive a snowline location from H13CO+ or HC18O+ emission, their true value as a snowline tracer will lie in the application in sources where water cannot be readily detected. For protostellar envelopes, the most straightforward way to locate the water snowline is through observations of

or HDO. Including all subarcsecond-resolution water observations from the literature, we derive an average burst interval of ∼10,000 yr, but high-resolution water observations of a larger number of protostars are required to better constrain the burst frequency.
Mapping Physical Parameters in Orion KL at High Spatial Resolution
Authors: Wilkins Olivia H. , Carroll P. Brandon , Blake Geoffrey A. 
Published: January 2022

Abstract
The Orion Kleinmann-Low nebula (Orion KL) is notoriously complex and exhibits a range of physical and chemical components. We conducted high-angular-resolution (subarcsecond) observations of 13CH3OH ν = 0 (∼0.″3 and ∼0.″7) and CH3CN ν
8 = 1 (∼0.″2 and ∼0.″9) line emission with the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate Orion KL’s structure on small spatial scales (≤350 au). Gas kinematics, excitation temperatures, and column densities were derived from the molecular emission via a pixel-by-pixel spectral line fitting of the image cubes, enabling us to examine the small-scale variation of these parameters. Subregions of the Hot Core have a higher excitation temperature in a 0.″2 beam than in a 0.″9 beam, indicative of possible internal sources of heating. Furthermore, the velocity field includes a bipolar ∼7–8 km s−1 feature with a southeast–northwest orientation against the surrounding ∼4–5 km s−1 velocity field, which may be due to an outflow. We also find evidence of a possible source of internal heating toward the Northwest Clump, since the excitation temperature there is higher in a smaller beam versus a larger beam. Finally, the region southwest of the Hot Core (Hot Core-SW) presents itself as a particularly heterogeneous region bridging the Hot Core and Compact Ridge. Additional studies to identify the (hidden) sources of luminosity and heating within Orion KL are necessary to better understand the nebula and its chemistry.
Dust Settling and Clumping in MRI-turbulent Outer Protoplanetary Disks
Authors: Xu Ziyan , Bai Xue-Ning 
Published: January 2022

Abstract
Planetesimal formation is a crucial yet poorly understood process in planet formation. It is widely believed that planetesimal formation is the outcome of dust clumping by the streaming instability (SI). However, recent analytical and numerical studies have shown that the SI can be damped or suppressed by external turbulence, and at least the outer regions of protoplanetary disks are likely weakly turbulent due to magneto-rotational instability (MRI). We conduct high-resolution local shearing-box simulations of hybrid particle-gas magnetohydrodynamics (MHD), incorporating ambipolar diffusion as the dominant nonideal MHD effect, applicable to outer disk regions. We first show that dust backreaction enhances dust settling toward the midplane by reducing turbulence correlation time. Under modest level of MRI turbulence, we find that dust clumping is in fact easier than the conventional SI case, in the sense that the threshold of solid abundance for clumping is lower. The key to dust clumping includes dust backreaction and the presence of local pressure maxima, which in our work is formed by the MRI zonal flows overcoming background pressure gradient. Overall, our results support planetesimal formation in the MRI-turbulent outer protoplanetary disks, especially in ring-like substructures.

Published: January 2022

Abstract
Recent studies using volume-limited samples of brown dwarfs have revealed the photometric evolution of single L and T dwarfs and unresolved binaries as they age and cool, in particular as they transition from L to T spectral types. We demonstrate that the near-infrared photometric evolution of the resolved components of L and T dwarf binaries is consistent with that of single objects using a volume-limited sample. In addition, we provide supporting evidence that the L9 dwarf WISE J185101.83+593508.6 is an unresolved binary and identify three more candidate or confirmed unresolved binaries all from being overluminous for their spectral type. We calculate a new binary fraction of 13.1% ± 1.8% for L0–T8 dwarfs.

VIETBIO [Innovative approaches to biodiversity discovery and characterisation in Vietnam] is a bilateral German-Vietnamese research and capacity building project focusing on the development and transfer of new methods and technology towards an integrated biodiversity discovery and monitoring system for Vietnam. Dedicated field training and testing of innovative methodologies were undertaken in Cuc Phuong National Park as part and with support of the project, which led to the new biodiversity data and records made available in this article collection.VIETBIO is a collaboration between the Museum für Naturkunde Berlin – Leibniz Institute for Evolution and Biodiversity Science (MfN), the Botanic Garden and Botanical Museum, Freie Universität Berlin (BGBM) and the Vietnam National Museum of Nature (VNMN), the Institute of Ecology and Biological Resources (IEBR), the Southern Institute of Ecology (SIE), as well as the Institute of Tropical Biology (ITB); all Vietnamese institutions belong to the Vietnam Academy of Science and Technology (VAST).The article collection "VIETBIO" (https://doi.org/10.3897/bdj.coll.63) reports original results of recent biodiversity recording and survey work undertaken in Cuc Phuong National Park, northern Vietnam, under the framework of the VIETBIO project. The collection consist of this “main” cover paper – characterising the study area, the general project approaches and activities, while also giving an extensive overview on previous studies from this area – followed by individual papers for higher taxa as studied during the project. The main purpose is to make primary biodiversity records openly available, including several new and interesting findings for this biodiversity-rich conservation area. All individual data papers with their respective primary records are expected to provide useful baselines for further taxonomic, phylogenetic, ecological and conservation-related studies on the respective taxa and, thus, will be maintained as separate datasets, including separate GUIDs also for further updating.

Published: January 2022

Purpose: Canopy light interception and extinction play a crucial role in determining crop yield. Developing new rice varieties with improved canopy architecture along with modified intrinsic photosynthetic mechanisms will ensure the global food security. However, a comprehensive understanding of local rice varieties addressing on such avenues have not been reported. Hence, our pioneering experiments were carried out to elucidate such underlying properties among locally developed two elite rice varieties viz; At-362 and Bg 94-1 grown in the Ampara district of Sri Lanka. Research Method: The field experiment was carried out at the Agro Tech Park, Malwatta (7°20'N and 81°44'E altitude 16.0 m above sea level) between October 2019 to January 2020 implemented with Randomized Complete Block Design with four replicates. The Photosynthetically Active Radiation (PAR) distribution on the above and below canopy level was measured during the pre and post-anthesis stages. Then leaf stomatal conductance, chlorophyll fluorescence parameters and the chlorophyll content were also measured. At harvest, the final biomass produced were compared. Findings: The result revealed that variety At-362 had a higher Leaf Area Index (LAI) of 2.64 at pre anthesis and tend to decline at the latter part of their growth cycle. The striking feature was the extinction coefficient (k) seems to be much lower (0.47) in the At-362 variety than the Bg 94-1 (0.60) depicting that the former has produced vertical leaves (erect-leaf type) while the latter tends to produce horizontal leaf plans in the canopy. Hence, light attenuation was high and eventually, the bottom canopy layer received much lower PAR. Furthermore, LAI had a strong negative correlation with understory PAR indicating that the canopy architecture with an improved light interception will lead to permit more light penetration and utilization through the improved quantum yield efficiencies than the horizontal canopies. Hence significantly (p<0.05) improved above-ground biomass and panicle weight were observed in At-362. Originality/value: This experiment depicts that rice yield could be further improved through introgression of canopy architectural features along with improved photosynthetic traits.
Effects of dietary supplementation of ginger, garlic and onion on semen profile, haematological and serum antioxidant status of rabbit bucks raised in the dry season of the humid tropic
Authors: Ajao B. H. , Ola S. I. 
Published: January 2022

Purpose: The study evaluated the semen, haematological and antioxidant status of rabbit bucks fed ginger, garlic and onion supplemented diets under a severely heat stressed condition. This is to evaluate the effect of heat stress and spice supplementation on seminal parameters, haematology and antioxidant capacity of rabbit buck raised in the tropics. Research method: Fifty - five bucks were allotted to 11 treatments comprising of control diet, three each of ginger, garlic and onion at 5g, 10g and 15g/kg feed plus positive control diet. Seminal, haematological and antioxidant traits of the bucks and their pen's Temperature – Humidity index (THI) were observed for 8 weeks. Findings: THI (29.30 - 31.10°C) recorded during the study indicated the prevalence of severe to very severe heat stress. Heat stress impacted negatively more on sperm morphology than on other seminal parameters. Sperm cell motility, viability and abnormality were similar within supplemented groups and the controls. Semen volume and concentration were highest in animals fed garlic at 10 and 15g/kg feed respectively. Spice supplementation had no significant effect (p>0.05) on the haematology and total antioxidant capacity (TAC) of the experimental animals. Originality/value: The study concluded that spice supplementation mitigated heat stress effect on sperm cell morphology and was not deleterious on haematology and TAC of the bucks.

Background and objective: Northern Italy was one of the first European territories to deal with the Coronavirus Disease 2019 (COVID-19) outbreak. Drastic emergency restrictions were introduced across the country to contain the spread and limit pressure on healthcare facilities. Nurses were at high risk of developing physical, mental and working issues due to professional exposure. The aim of this cross-sectional study was to investigate these issues among nurses working in Italian hematopoietic stem cell transplant (HSCT) programmes during the COVID-19 pandemic.
Methods: Data were collected online immediately after the first "lockdown" period in order to investigate the prevalence of physical issues, sleep disorders and burnout symptoms and explore correlations with COVID-19 territorial incidence in Northern Italian regions versus Central and Southern Italian regions.
Results: Three hundred and eight nurses working in 61 Italian HSCT Units responded to the survey. Depression, cough and fever were more frequently reported by nurses working in geographical areas less affected by the pandemic (p=0.0013, p<0.0001 and p=0.0005 respectively) as well as worst sleep quality (p=0.008). Moderate levels of emotional exhaustion (mean±SD - 17.4±13.0), depersonalization (5.3±6.1) and personal accomplishment (33.2±10.7) were reported without significant differences between territories.
Conclusions: different COVID-19 incidence among territories did not influenced nurses’ burden of symptoms in HSCT setting. However, burnout and insomnia levels should be considered by health care facilities in order to improve preventive strategies.

Published: January 2022

Rare cases of immune thrombocytopenia (ITP) occurring after SARS-CoV-2 mRNA vaccines have recently reached public attention. It has been reported in patients with previous ITP or other autoimmune diseases and in individuals with an apparent negative past medical history. The management and the outcome of these cases are still not well investigated and reported in the medical literature. A 23-year-old female with a past medical history of ITP, in stable complete remission for 3 years and on mycophenolate treatment received SARS-CoV-2 mRNA vaccine. She presented severe ITP recurrence with hemorrhagic symptoms after the second vaccine dose. A combined treatment with high-dose immunoglobulin and prednisone was successfully administered with a full recovery of platelet count. The patient remains in ITP remission and on mycophenolate therapy, five months later. At our Center, none of the other 76 adult “fragile patients” with ITP on immunosuppressive treatment who had received the SARS-CoV-2 mRNA vaccine, developed such a severe thrombocytopenic recurrence. Follow-up of large cohorts of patients receiving mRNA vaccine will answer the question as to whether it increases the risk of autoimmune conditions. So far, the benefits of the vaccination largely outweigh the risk of infection in these patients.

Published: January 2022

Background:
Large number of screen failures in trials often result in delayed drug approvals, an increase in the financial burden for conducting research, and limit the applicability of the study results to patients in the clinic.

Objectives:
This post hoc analysis was aimed at assessing the reasons for screen failures in a phase III, investigator-initiated clinical trial conducted in India.

Materials and Methods:
The study was conducted at the Tata Memorial Center, a tertiary cancer center in Mumbai, India. We maintained a log of all potential study candidates who underwent screening in our outpatient department between May 2016 and January 2020. This included the name of the study subject, hospital registration number, age, and sex. We also recorded the screening date and outcome of the screening process (whether enrolled in the study and if not, the reason for it) along with the number of patients who were finally randomized in the study. We evaluated factors that may have impacted screen failure including age, sex, and performance status (PS).

Results:
A total of 594 patients were screened. Of these, 422 were enrolled and 172 failed screening. Out of the 172 patients who were not enrolled, 105 (61%) did not meet the eligibility criteria and 67 (39%) refused to participate due to various reasons. The reasons for non-enrollment in the trial included the lack of a place to stay in Mumbai (35, 20.3%), patient wanted only a particular therapy (16, 9.3%), age over 70 years (15, 8.7%), poor PS (4, 2.3%), deranged organ function (13, 7.6%), active tuberculosis (2, 1.2%), primary tumor in the nasopharynx/thyroid/salivary gland/unknown primary (31, 18%), positivity for viral markers of infection (12, 7%), platinum-refractory disease (23, 13.4%), unwillingness to participate in research (15, 8.7%), patient not willing as they were not accompanied by a relative=1(0.06%) and other reasons (5, 2.9%). Age over 60 years (P = 0.001), and poor PS (P < 0.001) significantly increased the screen failure rate.

Conclusion:
The most common cause for screen failures is the nonfulfillment of the eligibility criteria, followed by patient-related reasons such as unavailability of a place to stay at the trial location. Broadening the eligibility criteria to better reflect the patients most commonly seen in the clinic will function both to decrease the rate of screen failures and increase the applicability of the study results.
