Published: June 2024

Abstract

Objectives
Congenital Hypogonadotropic Hypogonadism (CHH) is among the few causes of male infertility, which could benefit from a rationale treatment. Both gonadotropin and GnRH therapy proved effective in inducing spermatogenesis in patients with CHH. However, due to the small sample size of the studies available and the lack of randomized studies, a precise evaluation of the efficacy and a comparison among different treatments remain difficult. A meta-analysis was conducted to evaluate the efficacy of either gonadotropin or GnRH treatment in inducing spermatogenesis in subjects with CHH and azoospermia and to identify possible treatment response moderators.

Methods
An extensive Medline and Embase search was performed, including the following words: “gonadotropins” or “GnRH”, “infertility”, “hypogonadotropic”, “hypogonadism” and limited to studies in male humans.

Results
Overall, 41 and 22 studies were retrieved for gonadotropin and GnRH therapy in CHH patients, respectively. All considered the appearance of at least one spermatozoon in semen, whereas 23 and 9 considered sperm concentration upon gonadotropin and GnRH, respectively. The succes rate in obtaining at least one spermatozoon in the ejaculate and the achived sperm concentration were 0.70 [0.62-0.77] and 7.28 [5.19-9.36] x10^6/mL for gonadotropin therapy and 0.65 [0.52-0.77] and 6.48 [2.48-10.48] x10^6/mL for GnRH therapy. In studies using gonadotropins, worse results were obtained by hCG alone. Non differences were reported from studies using urinary-derived or recombinant FSH or from those enrolling or not patients previously treated with testosterone. Higher testis volume and lower LH and FSH at baseline were associated with a higher success rate upon gonadotropin therapy.

Conclusions
Gonadotropin therapy is a suitable option for inducing fertility in azoospermic CHH subjects. Protocols with combining FSH and hCG showed better results in terms of seminal outcomes than hCG therapy alone. These treatments appear to be more effective in subjects with lower baseline FSH and LH while previous TRT and FSH preparation do not affect the outcome.

(79) “SEXUAL RECESSION” IN THE MAINSTREAM AND SCIENTIFIC PRESS: AND YET SEXUALLY TRANSMITTED INFECTIONS (STIS) ARE ON THE RISE
Authors: Choucroun Dr Danielle 
Published: June 2024

Abstract

Objectives
In France, 2022/02, a survey (IFOP pour Sidaction, people aged 15 to 24) found that 44% of those polled had not had sex in the past year. This trend seems also to be confirmed in the USA, as shown by Professor Twenges's work, including a lack of interest for masturbation. Our study aims to highlight the today's possible causes of sexual inactivity, and to compare observations with sexual health data concerning STIs, abortion, after-morning pill, use of dating applications and use of pornography.

Methods
Review of the mainstream online press for the last five years with the keywords in french and in english sexual recession, sexual inactivity, decline in sexual activity. Review of the scientific literature on PubMed and Google Scholar for the last five years with the keywords sexual recession, sexual inactivity.

Results
Mainstream press and scientific literature agree to describe a decline in sexual activity, especially among those under 30. Causes are numerous, sexological (lack of sexual pleasure, sexual dysfunction, other), or not: psychological (anxiety, depression, bad self-esteem), societal (breakdown in social ties), iatrogenic, aesthetic (overweight), cultural (social media, video games), adverse socio-economic conditions (unemployment, students). The most surprising is the lack of perspective of these observations with sexual health data. Indeed public health data seem to challenge a situation of sexual recession. Especially in France, the HIV infection rates continues, the abortion rate does not decrease, for chlamydia and gonococci rates increase (Bulletin de Santé Publique VIH-IST 2021). According to World Health Organization, “more than 1 million sexually transmitted infections (STIs) are acquired every day worldwide”. Pornographic video viewing constitutes 25% of global video traffic.

Conclusions
Since a few years, the journalistic and scientific sources describe in various medias a “sexual recession” in different countries. The examination of sexual health data seem to challenge these observations and requires further studies.

(387) STIGMA TOWARDS ANAL SEX: A STUDY ON THE ITALIAN POPULATION
Authors: Fiacchino Dr Donatella , Salvatori Dr Gioele , Borrello Dr Lorenzo , Giunti Dr Daniel , Antonelli Prof Paolo 
Published: June 2024

Abstract

Objectives
Most research on anal sex is focused on the risks and prevalence of sexually transmitted infections. Anal sex behavior is also often under-reported, likely due to stigma. The present study aimed at understanding the correlation between attitude and stigma towards anal sex and sexual habits of people who engage in anal sex. Furthermore, it included a validation of the Italian version of the questionnaire “The Anal Sex Stigma Scales”.

Methods
The study was carried out as an online questionnaire (N = 1061, age 16-73), it included questions to investigate attitude and behavior around anal sex, the “The Anal Sex Stigma Scales”, questionnaires on social desirability, disgust propensity, attitudes towards homosexuality and sex wellbeing. Data analysis consisted of the computation of descriptive statistics and one-way analysis of variance (ANOVA), as well as of post hoc analyses for the latter.

Results
3 out of 4 participants had tried anal sex at least once. Women of any sexual orientation were mostly worried about pain (F = 7.370; p &lt; .001; η2 = .156) and getting dirty (F = 3.948; p &lt; .001; η2 =.090) during anal stimulation. Heterosexual men, on the other hand, were apprehensive about receiving anal penetration because of the social stigma around it (F = 15.743; p &lt; .001; η2 = .282). The hypothesis that fear of pain, disgust and negative attitudes towards homosexuality would be higher in participants who have never tried anal sex was partially supported by the data: this was only true for men.

Conclusions
The study showed significant gender differences in terms of the attitude and the habits: a significant association of fear of pain, disgust and refusal of trying anal sex in men, but not in women. It also revealed that the reasons for engaging in anal sex are different across genders, regardless of the sexual orientation.

Magnetic field at the Galactic centre from multiwavelength dust polarization
Authors: Akshaya M S , Hoang Thiem 
Published: June 2024

ABSTRACT
We have mapped the magnetic field (B-field) for a region of about 30 pc around the centre of our Galaxy, which encompasses the circumnuclear disc (CND), the minispiral, and the 20 and 50 km s−1 molecular clouds, using thermal dust polarization observations obtained from SOFIA/HAWC+ and JCMT/SCUPOL. We decompose the spectra of 12CO (J = 3 → 2) transition from this region into individual cloud components and find the polarization observed at different wavelengths might be tracing completely different layers of dust along the line of sight. We use modified Davis–Chandrasekhar–Fermi methods to measure the strength of B-field projected in the plane of the sky ($B_{{}_{\mathrm{POS}}}$). The mean $B_{{}_{\mathrm{POS}}}$ of the CND and the minispiral, probed at 53 μm is of the order of ∼2 mG. $B_{{}_{\mathrm{POS}}}\!\!\!\lt \!1$ mG close to the Galactic Centre, in the region of the ionized mini-cavity within the CND, and increases outwards. However, the longer wavelength polarization at 216 μm appears to come from a dust layer that is cooler and behind the CND and has a stronger B-field of about 7 mG. The B-field strength is lowest along the Eastern Arm of the minispiral, which is also the only region with Alfvén Mach number, $\mathcal {M}_{\mathrm{A}}\gt 1$ and mass-to-flux ratio, λ ≳ 1. Such an observed weak B-field could be a result of the low resolution of the observation, where the tangled B-fields due to the strong turbulence in the high density clumps of the CND are lost within the beam size of the observation.
Buoyancy torques prevent low-mass planets from stalling in low-turbulence radiative discs
Authors: Ziampras Alexandros , Nelson Richard P , Paardekooper Sijme-Jan 
Published: June 2024

ABSTRACT
Low-mass planets migrating inwards in laminar protoplanetary discs (PPDs) experience a dynamical corotation torque (DCT), which is expected to slow down migration to a stall. However, baroclinic effects can reduce or even reverse this effect, leading to rapid inward migration. In the radiatively inefficient inner disc, one such mechanism is the buoyancy response of the disc to an embedded planet. Recent work has suggested that radiative cooling can quench this response, but for parameters that are not necessarily representative of the inner regions of PPDs. We perform global 3D inviscid radiation hydrodynamics simulations of planet–disc interaction to investigate the effect of radiative cooling on the buoyancy-driven torque in a more realistic disc model. We find that the buoyancy response exerts a negative DCT – albeit partially damped due to radiative cooling – resulting in sustained, rapid inward migration. Models that adopt a local cooling prescription significantly overestimate the impact of the buoyancy response, highlighting the importance of a realistic treatment of radiation transport that includes radiative diffusion. Our results suggest that low-mass planets should migrate inwards faster than has been previously expected in radiative discs, with implications for the formation and orbital distribution of super-Earths and sub-Neptunes at intermediate distances from their host stars, unless additional physical processes that can slow down migration are considered.
Nine new M dwarf planet candidates from TESS including five gas giants
Authors: Eschen Yoshi Nike Emilia , Kunimoto Michelle 
Published: June 2024

ABSTRACT
We present the detection of nine new planet candidates orbiting M dwarfs, identified using an independent search and vetting pipeline applied to TESS Full-Frame Image data from Sectors 1 to 63. Our candidates include planets as small as 1.4 $\mathrm{ R}_{{\oplus }}$, with orbital periods up to 20 d. Among the nine new candidates, we identified five gas giants, which represent a rare and unexpected outcome of planet formation. Our findings add to the growing sample of giant planets around M dwarfs found by TESS. We discuss their follow-up potential for mass measurements through radial velocity observations and atmospheric characterization through transmission spectroscopy. We highlight TIC 12999193.01 as a particularly unique gas giant candidate in an eccentric orbit and excellent potential for atmospheric characterization.
T-Minkowski Noncommutative Spacetimes I: Poincaré Groups, Differential Calculi, and Braiding
Authors: Mercati Flavio 
Published: June 2024

Abstract
This paper introduces and investigates a class of noncommutative spacetimes that I will call “T-Minkowski,” whose quantum Poincaré group of isometries exhibits unique and physically motivated characteristics. Notably, the coordinates on the Lorentz subgroup remain commutative, while the deformation is confined to the translations (hence the T in the name), which act like an integrable set of vector fields on the Lorentz group. This is similar to Majid’s bicrossproduct construction, although my approach allows the description of spacetimes with commutators that include a constant matrix as well as terms that are linear in the coordinates (the resulting structure is that of a centrally extended Lie algebra). Moreover, I require that one can define a covariant braided tensor product representation of the quantum Poincaré group, describing the algebra of N-points. This also implies that a 4D bicovariant differential calculus exists on the noncommutative spacetime. The resulting models can all be described in terms of a numerical triangular R-matrix through RTT relations (as well as RXX, RXY, and RXdX relations for the homogeneous spacetime, the braiding, and the differential calculus). The R-matrices I find are in one-to-one correspondence with the triangular r-matrices on the Poincaré group without quadratic terms in the Lorentz generators. These have been classified, up to automorphisms, by Zakrzewski, and amount to 16 inequivalent models. This paper is the first of a series, focusing on the identification of all the quantum Poincaré groups that are allowed by my assumptions, as well as the associated quantum homogeneous spacetimes, differential calculi, and braiding constructions.

Published: June 2024

Abstract

Background
Nigeria has the largest global burden of HIV new infections in children despite global and national concerted efforts at the reduction of mother-to-child transmission of HIV. The goal of this study was to determine the associations between maternal characteristics, practices and mother-to-child transmission of HIV infection among mothers living with HIV.

Methods
This is a hospital-based descriptive cross-sectional study. Information was obtained using interviewer-administered questionnaire from the 240 participants. Data were analyzed with SPSS version 26, and P &lt; 0.05 was considered statistically significant.

Results
Out of the 240 mothers recruited, 129 (53.8%) were within 25–35 years of age, with a mean age of 31.08 ± 5.65. A total of 35 (14.6%) of the participants had at least a child with HIV infection. Maternal ART status before childbirth (AOR = 0.02, 95%CI = 0.01–0.05, P = &lt; 0 .001) was the singular determinant of having a child with HIV infection. Mothers who delivered outside the health facility were about four-fold at risk of having an infected child (AOR = 3.89, 95%CI = 1.82–8.50, P = 0.070).

Conclusion
The prevalence rate of mother-to-child transmission of HIV is high. Routine HIV testing services and the provision of accessible and affordable reproductive health services are recommended for all women of childbearing age.
Perturbative
T
-odd asymmetries in the Drell-Yan process revisited
Authors: Lyubovitskij Valery E. , Vogelsang Werner , Wunder Fabian , Zhevlakov Alexey S. 
Published: June 2024

We calculate the perturbative T-odd contributions to the lepton angular distribution in the Drell-Yan process. Using collinear factorization, we work at the first order in QCD perturbation theory where these contributions appear, O(αs2), and address both W± and γ/Z0 boson exchange. A major focus of our calculation is on the regime where the boson’s transverse momentum QT is much smaller than its mass Q. We carefully expand our results up to next-to-next-to-leading power in QT/Q. Our calculation provides a benchmark for studies of T-odd contributions that employ transverse-momentum dependent parton distribution functions. In the neutral-current case we compare our results for the T-odd structure functions to available ATLAS data.

Influence of deformation-induced misalignment on the performance of hydrodynamic bearings: a comparison between rigid and flexible journal results
Authors: Sun Xiaodong , Liu Yuanyuan , Chocholaty Bettina , Marburg Steffen 
Published: June 2024

Purpose
Prior investigations concerning misalignment resulting from journal deformation typically relied on predefined misaligned angles. Nevertheless, scant attention has been devoted to the determination of these misaligned angles. Furthermore, existing studies commonly treat the journal as rigid under such circumstances. Therefore, the present study aims to introduce a framework for determining misaligned angles and to compare outcomes between rigid and flexible journal configurations.

Design/methodology/approach
The bearing forces are considered as an external load leading to journal deformation. This deformation is calculated using the finite element method. The pressure distribution producing the bearing force is solved using the finite difference method. The mesh grids in the finite element and finite difference methods are matched for coupling calculation. By iteration, the pressure distribution of the lubricant film at the equilibrium position is determined.

Findings
Results show that the deformation-induced misalignment has a significant influence on the performance of the bearing when the journal flexibility is taken into account. The parametric study reveals that the misalignment relies on system parameters such as bearing length-diameter ratio and static load.

Originality/value
The investigation of this work provides a quantification method of misalignment of hydrodynamic bearings considering the elastic deformation of the journal, which assists in the design of bearing in a rotor-bearing system.

The effect of economic, environmental and social sustainability performance on accounting conservatism: the moderating role of good corporate governance
Authors: Khlifi Sawssen , Boujelbene Mohamed Ali , Chouaibi Jamel 
Published: June 2024

Purpose
This study aims to examine the impact of economic, environmental and social (EES) indicators of sustainability performance on accounting conservatism and the moderating effect of good corporate governance (GCG) on this relationship in European environmental, social and governance (ESG) firms.

Design/methodology/approach
To test the study’s hypotheses, this paper applied linear regressions with panel data from 136 European companies selected from the ESG index between 2015 and 2022.

Findings
The results show a positive effect of economic and environmental sustainability scores on the accounting conservatism level. However, social score has a negative and significant effect on the level of accounting conservatism. The findings also show that GCG accentuates these effects.

Research limitations/implications
The findings have several implications for companies, investors and academic researchers. For companies, EES reporting should be enhanced. For investors, sustainability performance is crucial in decision-making. The results show that exploring the interaction between sustainability performance scores and accounting conservatism is essential for academic researchers.

Originality/value
This paper is motivated by the limited research on EES sustainability scores and accounting conservatism around GCG, hence its pertinence for companies seeking to improve information quality.

Published: June 2024

AbstractIntroductionIn 2018, the Australasian College for Emergency Medicine (ACEM) and the Royal College of Pathologists of Australasia (RCPA) produced a guideline to encourage appropriate pathology requesting in the Emergency Department (ED).ObjectiveTo assess adherence to the ACEM/RCPA pathology testing guideline in a regional ED.Methods, Design, Setting and ParticipantsThis was a retrospective observational study conducted at a regional Australian ED over 7 days. Adults with a presenting complaint encompassed by the guideline were included. All blood tests were audited against the guideline recommendations and classified as indicated or non‐indicated. Chi‐squared analyses were performed to explore the association between presenting complaint and non‐indicated testing.Main Outcome MeasureThe primary outcome was the number of non‐indicated blood tests.ResultsForty percent of tests ordered were not clinically indicated, with non‐indicated testing occurring during 87% of encounters. The C‐reactive protein (CRP) was the test most frequently ordered outside of guidelines (94% non‐indicated). Patients presenting with lower abdominal pain accounted for nearly one‐quarter of all non‐indicated tests.ConclusionsBlood tests were commonly requested outside of the guideline recommendations and interventions to improve pathology stewardship are required.
