Summary. The aim. To analyze the anamnestic data, clinical symptoms, preoperative diagnosis, features of surgical intervention and the results of histological examination in a patient with mucocele of the appendix (MA), complicated by necrosis and perforation of the wall and formation of retroperitoneal space phlegmon (FRS).
Material and methods. An analysis of the case of MA, which was complicated by the atypical course and the development of retroperitoneal space phlegmon, which was diagnosed after multispiral computered tomography of the abdominal cavity (MSCT AC).
Results. The patient, despite periodic atypical complaints of discomfort in the right iliac region, did not seek medical attention and was not examined. Operated urgently after performing MSCT AC. Intraoperatively, a rupture of the MA was diagnosed with formation of FRS, which significantly complicated the course of the operation and the course of the postoperative period. Appendectomy, drainage of the abdominal cavity and retroperitoneal space were performed. Gradual improvement and recovery.
Conclusions: The acute situation resulting from the rupture of the MA, led to a complex operation. Performing MSCT AC at the prehospital stage makes it possible to diagnose the problem and perform the operation in a timely manner, without waiting for serious complications.

ABSTRACT
BACKGROUND & OBJECTIVE: The objective of our study is to evaluate the prevalence of anxiety, stress and depression in undergraduate MBBS students to correlate it with self-efficacy, life satisfaction and to evaluate its effect on academic performance. We have also considered the relation between academic year and last year score.
METHODOLOGY: A total of 800 self-administered questionnaires were filled by 1st year to final year undergraduate students using non-probability, purposive sampling. The 10-minute questionnaire comprised of four sections: (1) demographics (2) Depression, Stress and Anxiety Scale (DASS ) 21 scoring system (3) Satisfaction with Life Scale (4) General Self-Efficacy Scale. The demographic questions included participants’ age, gender, and year of study, residence and last year professional examination score percentage. A percentage below 50% was named as low achievers. A percentage from 50% to 70% was considered as moderate achievers and above 70% as high achievers.
RESULTS: In this sample of 505 students 180 (35.6%) were male undergraduates consisting of 18.6% from 1st year, 26.5% from 2nd year and 20.8%, 18% and 16% from 3rd year, 4th year and final year respectively. The depression, anxiety and stress rate were 69.5%, 78.6% and 63.4% respectively. Generally, depression, anxiety and stress were found more in females as compared to males. Anxiety was more common as compared to stress and depression. Students of 4th year were experiencing least psychological stress.
CONCLUSION: Moderate level of depression, stress and anxiety is necessary for good grades but excess of these psychological problems leads to emotional exhaustion and has a negative effect on learning and academic score. These psychological problems also lower the general self-efficacy of a student and are associated with low satisfaction with life.

Published: October 2020

Aim. The aim of our study was to assess the prevalence of contrast-induced nephropathy (CIN) in patients with chronic coronary artery disease (CAD) and its 1-year prognostic significance.Materials and methods. 462 patients with chronic CAD and indications to the interventions with intraarterial contrast media administration were included in the study. We conducted a prospective open cohort study (ClinicalTrials.gov NCT04014153). The primary endpoint was the development of CIN. The secondary endpoints were total mortality, cardiovascular mortality, myocardial infarction, stroke, gastrointestinal bleeding, acute decompensation of heart failure, coronary artery bypass grafting, repeat percutaneous coronary intervention.Results. 28 patients (6%) developed CIN. The rate of CIN in female patients was twice higher, than in males (9,29% vs. 4,66%). There was a trend towards less cases of CIN in patients without obesity (5,88% vs. 6,22%). CIN developed more frequently in patients with anemia (8,9% и 5,7%, р=0,3649, ОR 1,633,95% CI 0,6507-4,239). There was a trend to higher incidence of CIN in people with hyperuricemia (8% vs. 5,95%, р=0,6575, ОR 1,375,95% CI 0,3055-5,808). The rate of CIN in patients with diabetes mellitus was 2% higher, then without one. People, who suffered from myocardial infarction after 1 year of follow up, had the highest rate of CIN (26,7%), as well as patients with other major cardiovascular complications (18,1%). The rate of repeat percutaneous coronary interventions was 9,5%, the rate of acute decompensation of heart failure was 7%.Conclusion. The prevalence of CIN in patients with chronic CAD was 6%. After 1 year of follow up the rate of CIN was higher in patients who had myocardial infarction, repeat percutaneous coronary interventions and acute decompensation of heart failure.

Published: October 2020

Giriş
Bu çalışmanın amacı antenatal dönemde yapılan serum tarama testlerindeki biokimyasal markerlerin gebeliğin intrahepatik kolestazını öngörebilme özelliğinin araştırılmasıdır.
Materyal ve Method
Bu vaka - kontrol gruplu çalışmada retrospektif olarak hasta kayıtları değerlendirilmiştir. Çalışmaya 156 gebe kadın dahil edilmiştir ( Çalışma , 49 kolestaz tanısı alan gebe ve 116 kontrol grubu gebelerden oluşmaktadır ).
Sonuçlar
İkinci trimesterde taranan alfa -fetoprotein (AFP) MoM , unkonjuge estriol (E3) MoM ve total B-HCG MoM değerleri, her 2 grupta benzerdi (p=0.299 , p=0.571, p=0.285). Birinci trimester tarama testi parametresi olan PAPP-A MoM değerine bakıldığında , kolestaz tanısı almış grup ile kontrol grubu arasında fark saptanmamıştır (p=0.103).
Tartışma
Sonuç olarak çalışmamızda birinci ve ikinci trimesterdeki prenatal serum tarama testlerinde bakılan biokimyasal markerler intrahepatik kolestazı öngörmede yetersiz kalmıştır. Çalışmamızın retrospektif olması ve hasta populasyonunun az olması bunun nedenleri arasındadır. Daha anlamlı sonuçlar için hasta populasyonunun fazla olduğu prospektif bir çalışma yapılması gerektiği kanısındayız .

Abstract
The physical and chemical properties of cold and dense molecular clouds are key to understanding how stars form. Using the IRAM 30 m and NRO 45 m telescopes, we carried out a Multiwavelength line-Imaging survey of the 70 μm-dArk and bright clOuds (MIAO). At a linear resolution of 0.1–0.5 pc, this work presents a detailed study of parsec-scale CO depletion and HCO+ deuterium (D-) fractionation toward four sources (G11.38+0.81, G15.22–0.43, G14.49–0.13, and G34.74–0.12) included in our full sample. In each source with T < 20 K and n
H ∼ 104–105 cm−3, we compared pairs of neighboring 70 μm bright and dark clumps and found that (1) the H2 column density and dust temperature of each source show strong spatial anticorrelation; (2) the spatial distribution of CO isotopologue lines and dense gas tracers, such as 1–0 lines of H13CO+ and DCO+, are anticorrelated; (3) the abundance ratio between C18O and DCO+ shows a strong correlation with the source temperature; (4) both the C18O depletion factor and D-fraction of HCO+ show a robust decrease from younger clumps to more evolved clumps by a factor of more than 3; and (5) preliminary chemical modeling indicates that chemical ages of our sources are ∼8 × 104 yr, which is comparable to their free-fall timescales and smaller than their contraction timescales, indicating that our sources are likely dynamically and chemically young.

Abstract
We present optical and near-infrared (NIR) (ugriYJH) photometry of host galaxies of Type Ia supernovae (SN Ia) observed by the Carnegie Supernova Project-I. We determine host galaxy stellar masses and, for the first time, study their correlation with SN Ia standardized luminosity across optical and NIR (uBgVriYJH) bands. In the individual bands, we find that SNe Ia are more luminous in more massive hosts with luminosity offsets ranging between −0.07 ± 0.03 and −0.15 ± 0.04 mag after light-curve standardization. The slope of the SN Ia Hubble residual-host mass relation is negative across all uBgVriYJH bands with values ranging between −0.029 ± 0.029 and −0.093 ± 0.031 mag dex−1—implying that SNe Ia in more massive galaxies are brighter than expected. The near-constant observed correlations across optical and NIR bands indicate that dust may not play a significant role in the observed luminosity offset–host mass correlation. We measure projected separations between SNe Ia and their host centers, and find that SNe Ia that explode beyond a projected 10 kpc have a 50%– 60% reduction of the dispersion in Hubble residuals across all bands—making them a more uniform subset of SNe Ia. Dust in host galaxies, peculiar velocities of nearby SN Ia, or a combination of both may drive this result as the color excesses of SNe Ia beyond 10 kpc are found to be generally lower than those interior, but there is also a diminishing trend of the dispersion as we exclude nearby events. We do not find that SN Ia average luminosity varies significantly when they are grouped in various host morphological types. Host galaxy data from this work will be useful, in conjunction with future high-redshift samples, in constraining cosmological parameters.
Phase-space Spectral Line Deconfusion in Intensity Mapping
Authors: Cheng Yun-Ting , Chang Tzu-Ching , Bock James J. 
Published: October 2020

Abstract
Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sources that trace the matter density field. Spectral lines from different redshifts can fall in the same observed frequency and be confused, however, which is a major challenge in LIM. In this work, we develop a line deconfusion technique in map space capable of reconstructing the three-dimensional spatial distribution of line-emitting sources. If multiple spectral lines of a source population are observable in multiple frequencies, using the sparse approximation, our technique iteratively extracts sources along a given line of sight by fitting the LIM data to a set of spectral templates. We demonstrate that the technique successfully extracts sources with emission lines present at a few σ above the noise level, taking into account uncertainties in the source modeling and presence of continuum foreground contamination and noise fluctuations. As an example, we consider a Tomographic Ionized-carbon Mapping Experiment/CarbON C ii line in post-rEionisation and ReionisaTiOn epoch (TIME/CONCERTO)-like survey targeting [C ii] at the epoch of reionization, and reliably reconstruct the 3D spatial distribution of the CO interlopers and their luminosity functions at 0.5 ≲ z ≲ 1.5. We also demonstrate a successful deconfusion for the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission in the near-infrared wavelengths. We discuss a formalism in which the reconstructed maps can be further cross-correlated with a (galaxy) tracer population to estimate the total interloper power. This technique is a general framework to extract the phase-space distribution of low-redshift interlopers, without the need of external information, for any line deconfusion problem.

Abstract
We present a detection of molecular gas emission at z ∼ 1–5 using the technique of line intensity mapping. We make use of a pair of 3 mm interferometric data sets, the first from the Atacama Large Millimeter/submillimeter Array (ALMA) Spectroscopic Survey in the Hubble Ultra Deep Field, and the second from a series of Atacama Compact Array (ACA) observations conducted between 2016 and 2018, targeting the COSMOS field. At 100 GHz, we measure nonzero power at 97.8% and 99.9% confidence in the ACA and ALMA data sets, respectively. In the joint result, we reject the zero-power hypothesis at 99.99% confidence, finding

The Relative Role of Bars and Galaxy Environments in AGN Triggering of SDSS Spirals
Authors: Kim Minbae , Choi Yun-Young 
Published: October 2020

Abstract
We quantify the relative role of galaxy environment and bar presence on AGN triggering in face-on spiral galaxies using a volume-limited sample with 0.02 < z < 0.055, M

r
< 19.5, and σ > 70

selected from Sloan Digital Sky Survey (SDSS) Data Release 7. To separate their possible entangled effects, we divide the sample into bar and non-bar samples, and each sample is further divided into three environment cases of isolated galaxies, interacting galaxies with a pair, and cluster galaxies. The isolated case is used as a control sample. For these six cases, we measure AGN fractions at a fixed central star formation rate and central velocity dispersion, σ. We demonstrate that the internal process of the bar-induced gas inflow is more efficient in AGN triggering than the external mechanism of the galaxy interactions in groups and cluster outskirts. The significant effects of bar instability and galaxy environments are found in galaxies with a relatively less massive bulge. We conclude that from the perspective of AGN–galaxy coevolution, a massive black hole is one of the key drivers of spiral galaxy evolution. If it is not met, a bar instability helps the evolution, and in the absence of bars, galaxy interactions/mergers become important. In other words, in the presence of a massive central engine, the role of the two gas inflow mechanisms is reduced or almost disappears. We also find that bars in massive galaxies are very decisive in increasing AGN fractions when the host galaxies are inside clusters.
Black Hole Formation in the Lower Mass Gap through Mergers and Accretion in AGN Disks
Authors: Yang Y. , Gayathri V. , Bartos I. , Haiman Z. , Safarzadeh M. , Tagawa H. 
Published: October 2020

Abstract
The heaviest neutron stars and lightest black holes expected to be produced by stellar evolution leave the mass range 2.2 M

largely unpopulated. Objects found in this so-called lower mass gap likely originate from a distinct astrophysical process. Such an object, with mass 2.6 M

was recently detected in the binary merger GW190814 through gravitational waves by LIGO/Virgo. Here we show that black holes in the mass gap are naturally assembled through mergers and accretion in active galactic nucleus (AGN) disks, and can subsequently participate in additional mergers. We compute the properties of AGN-assisted mergers involving neutron stars and black holes, accounting for accretion. We find that mergers in which one of the objects is in the lower mass gap represent up to 4% of AGN-assisted mergers detectable by LIGO/Virgo. The lighter object of GW190814, with mass 2.6 M

, could have grown in an AGN disk through accretion. We find that the unexpectedly high total mass of 3.4 M

observed in the neutron star merger GW190425 may also be due to accretion in an AGN disk.

Published: October 2020

ObjectiveIn a large series of White patients with refractory uveitis due to Behçet disease (BD) being treated with infliximab (IFX), we assessed (1) long-term efficacy and safety of IFX, and (2) IFX optimization when ocular remission was achieved.MethodsOur multicenter study of IFX-treated patients with BD uveitis refractory to conventional immunosuppressant agents treated 103 patients/185 affected eyes with IFX as first biologic therapy in the following intervals: 3–5 mg/kg intravenous at 0, 2, 6, and then every 4–8 weeks. The main outcome variables were analyzed at baseline, first week, first month, sixth month, first year, and second year of IFX therapy. After remission, based on a shared decision between patient and clinician, IFX optimization was performed. Efficacy, safety, and cost of IFX therapy were evaluated.ResultsIn the whole series (n = 103), main outcome variables showed a rapid and maintained improvement, reaching remission in 78 patients after a mean IFX duration of 31.5 months. Serious adverse events were observed in 9 patients: infusion reactions (n = 4), tuberculosis (n = 1),Mycobacterium aviumpneumonia (n = 1), severe oral ulcers (n = 1), palmoplantar psoriasis (n = 1), and colon carcinoma (n = 1). In the optimization subanalysis, the comparative study between optimized and nonoptimized groups showed (1) no differences in clinical characteristics at baseline, (2) similar maintained improvement in most ocular outcomes, (3) lower severe adverse events, and (4) lower mean IFX costs in the optimized group (€4826.52 vs €9854.13 per patient/yr).ConclusionIFX seems to be effective and relatively safe in White patients with refractory BD uveitis. IFX optimization is effective, safe, and cost-effective.

ObjectiveRecurrent attacks of peritonitis due to familial Mediterranean fever (FMF) may lead to peritoneal adhesions and fallopian tube obstruction. Colchicine, which is the treatment of choice for FMF, may disturb cell division. Secondary amyloidosis, a complication of untreated FMF, may involve the testes and ovaries. Thus, FMF and colchicine may potentially affect fertility and pregnancy in patients with FMF. The aims of the study are to evaluate the causes of infertility and pregnancy outcome in FMF patients and to compare them with 2 groups: non-FMF patients with peritoneal female genital tuberculosis (FGTB) and normal healthy controls.MethodsThis is a retrospective study in which FMF patients with reproductive disorders were recruited from the National Center of Medical Genetics and Primary Health Care in Yerevan, Armenia. The patients with FGTB and the healthy controls with reproductive problems were recruited successively from a large gynecology clinic in Yerevan. Genetic analyses for FMF were performed using ViennaLab StripAssay.ResultsThe FMF group (211 patients) resembles the FGTB group (127 patients) regarding etiologies of infertility. However, in vitro fertilization (IVF) success rate and pregnancy outcome were comparable between the FMF patients and the control group (162 patients). Infertility in patients with FMF was clearly associated with a more severe disease and a lack of adequate colchicine treatment.ConclusionsColchicine medication and controlled FMF disease do not adversely affect the reproductive system and pregnancy outcome. However, a lack of an appropriate colchicine treatment may cause infertility and poor pregnancy outcome.
Addressing the Faculty Shortage Through Connections: Stories of Becoming a Nurse Educator
Authors: Ross Bonnie , Kerrigan Monica Reid 
Published: October 2020

Background:
The current nursing faculty shortage is projected to continue. This article addresses recruitment and retention by contributing to the public stories of successful nursing faculty.

Method:
Narrative inquiry was used to examine how the ways of knowing of three associate degree nurse educators evolved over time in the community college setting.

Results:
The educators' early stories portrayed an internal tension that was in sharp contrast to the capability and self-confidence of an expert nurse. Stories revealed their struggle to balance empathy and care (connected knowing) with logic and objectivity (separate knowing) when handling challenging student situations. Over time, the educators developed ways of integrating connected and separate knowing, becoming constructivist knowers.

Conclusion:

The findings validate the importance of providing meaningful support for novice educators. Private spaces to promote reflection and active dialoging with a trusted mentor will assist new faculty as they work through their integration of caring verses objective knowing.
