Abstract
We present an analysis of an unusual pattern of water vapor emission from the ∼2 Myr old low-mass binary system VV CrA, as observed in IR spectra obtained with VLT-CRIRES, VLT-VISIR, and Spitzer-IRS. Each component of the binary shows emission from water vapor in both the L (∼3 μm) and N (∼12 μm) bands. The N-band and Spitzer spectra are similar to those previously observed from young stars with disks and are consistent with emission from an extended protoplanetary disk. Conversely, the CRIRES L-band data of VV CrA A show an unusual spectrum, which requires the presence of a water reservoir with high temperature (T ≳ 1500 K), column density (N
H2O ∼ 3 × 1020 cm−2), and turbulent broadening (v ∼ 10 km s−1) but very small emitting area (A ≲ 0.005 au2). Similarity to previously observed water emission from V1331 Cyg and SVS 13 suggests that the presence of such a reservoir may be linked to evolutionary state, perhaps related to the presence of high accretion rates or winds. While the inner disk may harbor such a reservoir, simple Keplerian models do not match well with emitting line shapes, and alternative velocity fields must be considered. We also present a new idea, that the unusual emission could arise in a circumplanetary disk, embedded within the larger VV CrA A protoplanetary disk. Additional data are likely required to determine the true physical origin of this unusual spectral pattern.
Dropouts of Fully Stripped Ions in the Solar Wind: A Diagnostic for Wave Heating versus Reconnection

Published: September 2022

Abstract
The SWICS instrument on board the ACE satellite has detected frequent intervals in the slow solar wind and interplanetary coronal mass ejections in which C6+ and other fully stripped ions are strongly depleted, though the ionization states of elements such as Si and Fe indicate that those ions should be present. It has been suggested that these “outlier” or “dropout” events can be explained by the resonant cyclotron heating process, because these ions all have the same cyclotron frequency as He2+. We investigate the region in the corona where these outlier events form. It must be above the ionization freeze-in height and the transition to collisionless plasma conditions, but low enough that the wind still feels the effects of solar gravity. We suggest that the dropout events correspond to relatively dense blobs of gas in which the heating is reduced because local variations in the Alfvén speed change the reflection of Alfvén waves and the turbulent cascade. As a result, the wave power at the cyclotron frequency of the fully stripped ions is absorbed by He2+ and may not be able to heat the other fully stripped ions enough to overcome solar gravity. If this picture is borne out, it may help to discriminate between resonant cyclotron heating and stochastic heating models of the solar wind.
Revisiting the Mass-excitation (MEx) Diagram using the MaNGA Data Set
Authors: Barrera-Ballesteros J. K. , Sánchez S. F. 
Published: September 2022

Abstract
The diagram comparing the flux ratio of the [O  iii] and Hβ  emission lines with the total stellar mass of galaxies (also known as the mass-excitation diagram, MEx) has been widely used to classify the ionization mechanism in high redshift galaxies, dividing star-forming galaxies from those where active galactic nuclei are important. This diagram was mainly derived using single-fiber spectroscopy from the SDSS-DR7 survey. In this study, we revise this diagram using the central and integrated spectral measurement from the entire Integral Field Spectroscopic MaNGA sample. Our results suggest that along with these physical parameters, the equivalent width of the Hα  emission line is also required to constrain the ionization mechanism of a high-redshifted galaxy. Furthermore, the location of a galaxy in the excitation-mass diagram varies depending on the use of central or integrated properties.
Determination of some edible oils adulteration with paraffin oil using infrared spectroscopy
Authors: Bunaciu Andrei A. , Fleschin Serban , Aboul-Enein Hassan Y. 
Published: September 2022

The spectroscopy of molecular vibrations using mid-infrared or near-infrared techniques was used more and more to characterize different compounds, including edible oil, in order to monitor any changes and to detect fraudulent modifications. This article presents a new method for quantitative adulteration of extra virgin olive oil (EVOO) or corn germ oil (CGO) with a mineral oil, such as paraffin oil (PO). A Fourier transform infrared (FT-IR) spectrometric method, using ATR spectra, was developed for the rapid, direct measurement of edible oils adulteration. The results indicate the efficiency of the proposed method for the detection of paraffin oil in adulteration of EVOO and CGO with RSD (&lt; 3.0%).

Acute poisoning in children: Etiology, structure, treatment tactics and outcomes
Authors: Karpushkina Ekaterina S. , Zhdanova Olga A. , Batishcheva Galina A. 
Published: September 2022

Introduction: Acute poisoning is often observed in children and can have serious consequences since it is character­ized by rapid development of symptoms and obvious disfunction of vital organs.
Materials and methods: Retrospective analysis of the case histories of the children with acute poisoning admitted to Voronezh Regional Children’s Clinical Hospital No. 1 in 2016–2019 was carried out. Anamnesis, clinical and lab­oratory studies and effective treatment criteria were entered into electronic spreadsheets and served as the basis for a database on children’s poisoning.
Results and discussion: Analysis of 183 case histories of children with intoxication aged 4 months to 17 years old was performed. Distribution per age showed bimodal peaks at 1–2 years and 13–14 years. Poisoning was accidental in 96.2% of the cases, and 3.8% of the adolescents reported suicide cases. In the group of young children, acute drug poisoning is more frequent in girls (P < 0.05). In the older groups, there is no gender difference in frequency of poisoning cases.
Early call for medical help is typical for the adolescent age group. Correlation between time of help-seeking and chil­dren’s age is statistically significant (correlation coefficient r = 0.38, P < 0.05).
Conclusion: Study of poisoning issue in children will allow to carry out targeted preventive measures to reduce the number of poisoning cases, prevent their consequences and to determine the most rational modus operandi for medical personnel for effective and safe pharmacotherapy.
Graphical abstract:
In pediatric practice, intoxication by poisons and drugs is among the most common reasons for seeking medical help and hospitalization in intensive care units. It is important to study and record dynamics, structure and frequency of acute poisoning with subsequent development of prevention and treatment methods.

Comparison of the Functional Optical Zone in Eyes With High Myopia With High Astigmatism After SMILE and FS-LASIK
Authors: Liu Shengtao , Zhang Xiaoxue , Niu Lingling , Yu Zhiqiang , Zhou Xingtao , Zhao Jing 
Published: September 2022

PURPOSE:
To compare the functional optical zone (FOZ) in eyes with high myopia with high astigmatism after small incision lenticule extraction (SMILE) and femtosecond laser–assisted laser in situ keratomileusis (FS-LASIK).

METHODS:
In total, 45 eyes of 45 patients with high myopia with astigmatism greater than 2.00 diopters (D) who underwent SMILE or FS-LASIK were enrolled. The FOZ, optical zone decentration, and corneal aberrations were analyzed using Scheimpflug imaging. These values were then compared between the two groups 6 months postoperatively.

RESULTS:

No postoperative complications were observed during follow-up. The mean FOZ diameter was 5.03 ± 0.31 mm for the FS-LASIK group and 5.24 ± 0.27 mm for the SMILE group (
P
= .007), corresponding to reductions of 1.18 ± 0.23 and 1.01 ± 0.21 mm, respectively, compared with the programmed optical zone (POZ) (
P
= .013). A significant difference was noted in the FOZ on the short axis between the two groups (
P
= .002), whereas no significant difference was observed on the long axis (
P
= .088). The FOZ area in the FS-LASIK and SMILE groups was 65.39 ± 6.14% and 70.09 ± 5.46% of the POZ area, respectively (
P
= .010). There was no significant difference in decentration between the two groups (0.29 ± 0.13 mm for the FS-LASIK group vs 0.30 ± 0.13 mm for the SMILE group,
P
= .798). A significant increase in spherical aberration was observed in the FS-LASIK group (
P
< .001). However, the induction of vertical coma was higher in the SMILE group than in the FS-LASIK group (
P
= .002).

CONCLUSIONS:
Eyes with high myopia with high astigmatism following SMILE achieved a larger FOZ and less spherical aberration but a larger vertical coma introduction than following FS-LASIK.

Prevalence, phenotype and genotype characteristics of antibiotic resistance in coastal beach practitioners of tropical China
Authors: Long Wenfang , Li Tianjiao , Yi Guohui , Liang Feng , Hu Gaoyao , Wu Jizhen , Huang Hairong , Li Mingxue 
Published: September 2022

Objective:
To investigate the genetic mechanism and prevalence of antibiotic resistance among the practitioners of two bathing beaches in tropical China.

Methods:
Totally 259 strains were isolated from the rectal swabs of the practitioners and screened by MacConkey agar. A questionnaire survey was conducted. Kirby-Bauer test was used for phenotype, and double disc inhibition synergy test was used for extended-spectrum β -lactamase-producing Enterobacteriaceae (ESBL-E), which was further confirmed by VITEKII instrument. The genotype was detected by polymerase chain reaction, and the similarities of ESBL-E were analyzed using pulsed-field gel electrophoresis.

Results:
The prevalence of ESBL-E was 13.1% (34/259), of which, CTX-M genes accounted for 44.1% (15/34), mainly CTX-M-14 and CTX-M-27. Moreover, 19.1% (4/21) of the isolates were homologous. The resistance phenotypes of ESBL-E to chloramphenicol, ciprofloxacin, levofloxacin, ceftazidime, cefepime and gentamicin were different between two beaches(P<0.05). The prevalence of ESBL-E was caused by CTX-M genes at the island beach, while a high prevalence of ESBL-E was found at the city beach and clone transfer occurred.

Conclusions:
ESBL-E-associated gentamicin antibiotic resistance risk may be greater for island beach practitioners. The city beach populations could face more potential risks owing to severe resistance and metastatic ability of ESBL-E. The environmental exposure mechanisms and transfer role of antibiotic resistance at public beaches with high density should be investigated.

Published: September 2022

Introduction
Compared to anterior cervical discectomy and fusion (ACDF), the motion preservation of cervical disc arthroplasty (CDA) provides an attractive alternative with similar short-term results. However, there is a paucity of the economics of performing CDA over ACDF.

Study Design:
This was retrospective study.

Objective:
The objective of this study is to evaluate relative-value-units (RVUs), operative time, and RVUs-per-minute between single-level ACDF and CDA. Secondary outcomes included 30-day readmission, reoperation, and morbidity.

Methods:
Adults who underwent ACDF or CDA in 2011–2019 National Surgical Quality Improvement Program database datasets. Multivariate quantile regression was utilized.

Results:
There were 26,595 patients (2024 CDA). ACDF patients were older, more likely to be female, discharged to inpatient rehabilitation, and have a history of obesity, smoking, diabetes, steroid use, and the American Society of Anesthesiologists-class ≥3. ACDF had greater median RVUs-per-case (41.2 vs. 24.1) and RVUs-per-minute (0.36 vs. 0.27), despite greater operative-time (109 min vs. 92 min) (P < 0.001). ACDF predicted a 16.9 unit increase in median RVUs per case (P < 0.001, confidence interval [CI]95: 16.3–17.5), an 8.81 min increase in median operative time per case (P < 0.001, CI95: 5.69–11.9), and 0.119 unit increase in median RVUs-per-minute (P < 0.001, CI95: 0.108–0.130). ACDF was associated with greater unadjusted rates of readmission (3.2% vs. 1.4%) morbidity (2.3% vs. 1.1%) (P < 0.001), but similar rates of reoperation (1.3% vs. 0.8%, P = 0.080). After adjusting for significant patient-related and procedural factors, readmission (odds ratio [OR] = 0.695, P = 0.130, CI95: 0.434–1.113) and morbidity (OR = 1.102, P = 0.688, CI95: 0.685–1.773) was similar between ACDF and CDA.

Conclusions:
Median RVUs-per-minute increased by 0.119 points for ACDF over CDA, or $257.7/h for each additional-hour of surgery. Adjusted 30-day outcomes were similar between procedures. Reimbursement for CDA does not appear to be in line with ACDF and may be a barrier to widespread usage.
Pregnancy outcome among high-risk pregnant women in the rural area of Belagavi
Authors: Chate Sphurti Uday , Metgud Chandra Shrishail 
Published: September 2022

Background:
India has around 25% high-risk pregnant mothers, which leads to about 75% perinatal morbidities.(1) The early prediction of a high-risk pregnancy and planning interventions can help in preventing complications and result in good pregnancy outcomes.

Aims:
To study the pregnancy outcome among the high-risk pregnant women of a rural area and to associate pregnancy outcomes of high-risk pregnant women with modified Coopland’s criteria.

Material and Methods:
Study design: 1-year Longitudinal study from 2016 to 2017, Study population: The high-risk pregnant women attending PMSMA camp, Study area: Kinaye, Primary Health Centre, Belagavi. Sample size: 147, Data collection was done using a pretested predesigned questionnaire after obtaining patient consent and ethical clearance. Chi-square test was used to study the association of variables and categorical data presented as percentages.

Results:
Among the participants, 40.4% of the pregnant women had low-risk scores; 45.9% had high-risk scores, and 13.7% had severe-risk scores according to Coopland’s high-risk pregnancy scoring. Nearly 29.5% high-risk pregnancies resulted in bad fetal outcomes. As Coopland’s score in the high-risk group increased, the chance of having good fetal outcomes decreased, and this association was found to be statistically significant.

Conclusions:
70.5% of the high-risk mothers had good pregnancy outcomes. The scoring system can be used by health workers for the prediction of high-risk pregnancy and plan treatment and preventive measures.

Assessment of the efficacy of digital panoramic radiographs in analyzing changes in bone mineral density in postmenopausal women
Authors: Jacob Lisa Elizabeth , Subramanian Kailasam , Srinivasan Srividhya , Krishnan Meenakshi , Krishnan Anand , Mathew Anju 
Published: September 2022

Introduction:
Osteoporosis is described by the World Health Organization (WHO) as a ‘progressive systemic skeletal disease characterized by low bone mass, microarchitectural deterioration of bone tissue, a consequent increase in bone fragility, and susceptibility to fracture. The maxilla and mandible are also affected by osteoporotic changes and these may be visualized using an Orthopantomogram.

Aims and Objectives:
To determine the radiomorphometric indices in the digital orthopantomograms, to determine the bone mineral density (BMD) of the lumbar spine and femur using DXA (Dual-Energy X-ray Absorptiometry) scan, to compare the measured indices between the BMD categories and to assess the correlation of these indices with the measured BMD.

Materials and Methods:
The study population included 30 postmenopausal female patients. The BMD was measured at the lumbar spine and at the femur and the patients were divided into three groups of 10 subjects based on their BMD status (normal, osteopenia, and osteoporosis). The patients were then subjected to panoramic radiography and four panoramic indices were assessed (simple visual estimation, mandibular cortical index, mental index, and antegonial index). The measured indices were compared between the three BMD categories. The correlation between the indices and the BMD was also observed.

Results:
The measured indices showed significant difference among the BMD categories. The quantitative indices also demonstrated a positive correlation with the measured BMD of the lumbar spine and the femur.

Conclusion:
Panoramic radiography may be used as a diagnostic tool for screening and identifying subjects who are likely to have osteoporosis.

Authors: Sharma Aditi , Goel Naveen Krishan , Prashar Savita , Choudhary Kshitij 
Published: September 2022

Background:
In India, premarital partnerships whether involving sex or not are widely unacceptable. Various studies in India have reported heightened premarital sexual activities among youngsters.

Objective:
The objective of the study was to assess the involvement of youth in premarital sexual practices studying at Panjab University.

Methods:
The cross-sectional study was conducted at Panjab University situated in Chandigarh, India between February and August 2020. Purposive sampling was used to recruit students. Data was collected using a pre-tested, semi-structured, self-administered questionnaire. The nature of the data was quantitative and was analyzed through SPSS version 20.

Results:
A total of 211 (female/male: 51.7%/48.3%, mean age: 22.5 years) respondents were enrolled. Prevalence of premarital sex was 68.7% with an average age of sexual debut 18.5 years. 62.1% of respondents were practicing unprotected sex. 91% of respondents were involved in vaginal sex, 61.4% in oral sex, 29% in online sex, and 19.3% in anal sex. 66.8% of respondents were involved in the habit of masturbation. In students having a positive premarital sexual background, 78.2% of respondents had sexting, 38.8% had friends with benefits, 33.9% had one-night stands, 4.8% had a threesome and 2.3% had gay sex. Out of all the respondents involved in premarital sexual practices, 86.9% were satisfied with sexual life.
