Введение. Существуют разные точки зрения относительно целесообразности рутинного облучения над-подключичных лимфоузлов (НПЛУ) при проведении адъювантной лучевой терапии на зоны регионарного лимфооттока у пациенток с ранним раком молочной железы (РМЖ).
Цель. Изучить возможность безопасного отказа от облучения НПЛУ у больных ранним РМЖ с поражением 1–3 подмышечных лимфоузлов (ЛУ) или 1–2 сигнальных ЛУ и отсутствием дополнительных факторов риска.
Материалы и методы. В проспективное рандомизированное исследование за период с февраля 2022 по октябрь 2024 г. включена 121 больная ранним РМЖ. При принятии решения об объеме послеоперационной лучевой терапии все пациентки были разделены на две группы. В контрольной группе послеоперационная лучевая терапия проводилась в стандартном объеме — облучение оставшихся тканей молочной железы или мягких тканей передней грудной с подмышечными ЛУ I, II, III уровней и надключичными ЛУ; в исследуемой группе из объема облучения исключались подмышечные лимфоузлы III уровня и надключичные лимфоузлы.
Результаты. На момент проведения промежуточного анализа в исследование была включена 121 больная. У 52 женщин время наблюдения превысило 24 мес. В этой группе выполнен сравнительный анализ показателей локорегионарного контроля у 44 пациенток исследуемой группы (без облучения НПЛУ) и 8 больных контрольной группы, которым послеоперационная лучевая терапия проводилась в стандартном объеме. Двухлетняя выживаемость без признаков локорегионарного рецидива, в том числе в ипсилатеральной над-подключичной области, в обеих группах составила 100 %. Двухлетняя безрецидивная выживаемость составила 97,7 % в исследуемой группе и 100 % контрольной группе [p > 0,2]. У 1 пациентки в исследуемой группе установлена генерализация процесса с поражением костей.
Заключение. Деэскалация лучевой терапии у больных ранним РМЖ с поражением не более 3 подмышечных лимфоузлов в первые 2 года наблюдения не приводит к снижению показателей безрецидивной выживаемости и не увеличивает риск возникновения рецидива РМЖ в над-подключичной области.

Abstract
Variability studies offer a compelling glimpse into black hole dynamics, and Neutron Star Interior Composition Explorer's (NICER’s) remarkable temporal resolution propels us even further. NICER observations of an active galactic nucleus (AGN), NGC 4051, have charted the geometry of the emission region of the central supermassive black hole. Our investigation of X-ray variability in NGC 4051 has detected extreme variations spanning a factor of 40–50 over a mere 10–12 hr. For the first time, we have constrained the X-ray power spectral density (PSD) of the source to 0.1 Hz, corresponding to a temporal frequency of 104 Hz in a galactic X-ray binary with a mass of 10 M
⊙. No extra high-frequency break/bend or any quasiperiodic oscillations are found. Through detailed analysis of energy-dependent PSDs, we found that the PSD normalization, the high-frequency PSD slope, as well as the bending frequency remain consistent across all energies within the 0.3–3 keV band, revealing the presence of a constant temperature corona. These significant findings impose critical constraints on current models of X-ray emission and variability in AGN.

Abstract
ASASSN-14li is a low-redshift (z
= 0.0206) tidal disruption event (TDE) that has been studied extensively across the entire electromagnetic spectrum and has provided one of the most sensitive measurements of a TDE to date. Its X-ray spectrum is soft and thermal (kT ∼ 0.05 keV) and shows a residual broad absorption feature between 0.6 and 0.8 keV, which can be associated with a blueshifted O vii line (rest-frame energy 0.57 keV) resulting from an ultrafast outflow at early times (within 40 days of optical discovery). By carefully accounting for photon pileup and using XSTAR photoionization models tailored to the evolving disk continuum properties, we analyze the entire archival X-ray data from XMM-Newton and track the evolution of this absorption feature for ∼4.5 yr post-disruption. Our main finding is that the absorption feature is transient and intermittent. Assuming the same underlying physical model (i.e., outflows) for the recurring absorption feature in ASASSN-14li, the outflow is seen to disappear and reappear multiple times during the first ∼1.5 yr of its evolution. No observable spectral imprint is detected thereafter. While theoretical studies suggest the launch of outflows in the early phases of the outburst during the super-Eddington regime, the outflow’s intermittent behavior for multiple years after disruption is unusual. We discuss this peculiar behavior within the context of varying inner-disk truncation, radiation pressure, and magnetically driven outflow scenarios.
Electrodynamics and Dissipation in the Binary Magnetosphere of Premerger Neutron Stars
Authors: Mahlmann Jens F. , Beloborodov Andrei M. 
Published: February 2025

Abstract
We investigate the energy release in the interacting magnetospheres of binary neutron stars (BNSs) with global 3D force-free electrodynamics simulations. The system dynamics depend on the inclinations χ
1 and χ
2 of the stars’ magnetic dipole moments relative to their orbital angular momentum. The simplest aligned configuration (χ
1 = χ
2 = 0∘) has no magnetic field lines connecting the two stars. Remarkably, it still develops separatrix current sheets warping around each star and a dissipative region at the interface of the two magnetospheres. A Kelvin–Helmholtz (KH)–type instability drives significant dissipation at the magnetospheric interface, generating local Alfvénic turbulence and escaping fast magnetosonic waves. Binaries with inclined magnetospheres release energy in two ways: via KH instability at the interface and via magnetic reconnection flares in the twisted flux bundles connecting the companions. Outgoing compressive waves occur in a broad range of BNS parameters, possibly developing shocks and sourcing fast radio bursts. We discuss implications for X-ray and radio precursors of BNS mergers.

Authors: Xie Guang-Long , Zhang Guoyi , Meng Kaibaryer , Köhler Frank 
Published: February 2025

We document type material of 41 nominal species from mainland China that were originally assigned to Diplommatina. This catalogue is based on inspection of the Heude Type collection in the National Zoological Museum of China, Beijing and complemented with information on types held by other international museums from a comprehensive literature review. We designate lectotypes of five nominal species, Diplommatina abbreviata Heude, 1890, D. confusa Heude, 1885, D. intermedia Heude, 1890, D. minuscula Heude, 1890, D. pupinella Heude, 1885 and D. pyra Heude, 1885.
In addition, a new species, Diplommatina yipingica Zhang, sp. nov., is described from Qingdao City, Shandong Province. A new name, D. yunnanensis, is introduced for Diplommatina minuscula Chen & Zhang, 1998, which is a junior homonym of D. minuscula Heude, 1890.

Published: February 2025

Cet article met en exergue les bénéfices du dialogue entre art et anthropologie à partir d’une recherche-création co-créée entre l’auteure et un danseur sénégalais. Quelle est la valeur pour la connaissance (anthropologique et artistique) lorsque la création chorégraphique et l’ethnologie se rencontrent ? En interrogeant les différences et les convergences en matière de processus de création et de représentation d’une performance, l’auteure met en lumière les enjeux interculturels au sein de la création, en miroir avec les logiques sociales. Les mécanismes d’exclusion et de racisme structurel au sein du champ chorégraphique (suisse) ainsi que dans la société y sont visibilisés. Visant à contribuer aux connaissances sur la créativité, la genèse du geste et la transmission du mouvement par un exemple venu d’ailleurs, l’article rend compte d’une ethnographie collaborative éthique, soulignant le potentiel de la recherche-création pour amenuiser la violence épistémique inhérente à la rencontre ethnographique, notamment dans le rapport enquêté-enquêteur.

A population of red swamp crayfish Procambarus clarkii, (Girard, 1852) was studied in four wetland classified Ramsar sites in Morocco which are Merja Fouwarat, Merja Zerga, and Rmel plateau and Bas Loukous. The aim of this study was to collect the first information on the size and weight of Procambarus clarkii for the reasons of its invasion success in the wetlands Ramsar site in Morocco. Also, comparing the size and weight of the four crayfish populations can provide valuable information on the evolution of this species in the study area, and on the degree of adaptation and survival of this population in Morocco. A total of 10,007 specimens were collected from January 2016 to December 2018, and analysed for sex, weight and total length. The study was carried out monthly and for three periods per day in order to evaluate the breeding period and identify the peak movement period of this species. The maximum weight was noted at the low Loukous wetland in 2016 which is 18 g, in the same area the maximum size has been determined which is 17.5 cm. The Merja Fouwarat and Lower Loukous wetland shares the same minimum size, which is 6 cm. The minimum weight in our sample is 6.3 g was found in the Low Loukous Wetland in 2017. The results of this study showed also that these four wetlands show a favorable habitat for the development of the red crayfish population, and the differences between the total length TL), weight (W) and sex are statistically significant.

Published: February 2025

Abstract
Background and Objectives: Hepatitis B virus (HBV) poses a significant public health challenge worldwide, contributing to substantial morbidity and mortality. Despite the availability of effective vaccines, immunoglobulins and antiviral medications, HBV prevalence remains high in developing regions. This study investigates the potential risk factors associated with HBV infection in the Kurdistan region of Iraq to aid in developing targeted prevention strategies.

Design and Methods: A cross-sectional study was conducted involving 4091 participants from Duhok and Zakho, in Kurdistan region of Iraq. Data on demographics and potential risk factors were collected via a structured questionnaire. HBV surface antigen (HBsAg) was screened using enzyme-linked immunosorbent assay (ELISA) to determine infection status. Statistical analysis included univariate and multivariate logistic regression to identify independent risk factors.

Results: The mean age of enrolled participants was 29.33 years ± 10.74. Among them, 2851/4091 (69.69%) were females, 3385/4091 (82.74%) were residents of city and 3682/4091 (88.68%) were married. The prevalence of HBV infection among them was 3.67% (150/4091) and the following factors were significantly associated with HBV infection: female gender (p = 0.001), rural residency (p = 0.001), being married (p = 0.0014). Though a history of general operation and tattooing was found to be associated with HBV infection, this association was lost in multivariate analysis (p > 0.05) possibly due to confounding effect. A history of receiving blood or dental procedure was not significantly associated with HBV infection (p > 0.05).

Conclusion: The prevalence of HBV infection in Duhok and Zakho remains high and several predictive factors were identified which can be used to target infection control measures. Future research should focus on a population-based study to investigate the prevalence and risk factors of HBV infection to better inform public health policies.

Water sector value chain challenges: The case of Chris Hani District Municipality
Authors: Twalo Thembinkosi 
Published: February 2025

Background: This study examined the challenges faced by the water sector value chain in the Chris Hani District Municipality (CHDM). The investigation was prompted by the issues related to water shortages and the poor quality of potable water in the area.Aim: The aim of this study was to identify the challenges in the water sector that are responsible for the precarious water provision services that are experienced at CHDM.Setting: The study was undertaken at CHDM, Eastern Cape, South Africa.Methods: The study used qualitative research techniques to delve deeper into the water issues at CHDM, and 10 sampled participants were interviewed.Results: The results show that the CHDM does not seem to adhere to some of the regulations of the Water Services Act of 1997. There is also a continuation of the non-payment culture by some water consumers because of poor affordability, resistance and municipal billing challenges.Conclusion: Regarding the interplay between water as a constitutional right and water as a business, the study concludes that consumers who can afford to pay should do so, while the indigent should be subsidised by the government. In terms of infrastructure, bulk water supply should be upgraded, dilapidated infrastructure should be replaced, revenue collection should be improved and there should be ring-fenced revenue for the provision of water services.Contribution: The study’s contribution is primarily on addressing some of the service delivery issues such as the municipality’s performance in relation to the provision of water services.
We are treated differently: Experiences of men who have sex with men in South African clinics
Authors: Ravele Tshivhase T. , Seretlo Raikane J. , Mokgatle Mathildah M. 
Published: February 2025

Background: Men who have sex with men (MSM) are regarded as a key population that needs specialised healthcare services to address their healthcare needs. This is because of their sexual practices. Men who have sex with men encounter positive and negative experiences when accessing healthcare services in public health care facilities. This study explored and described the experiences of MSM about accessing healthcare services in public healthcare facilities. The study was conducted in Ekurhuleni district, situated in the East of Gauteng province, South Africa.Methods: A descriptive, explorative, qualitative approach was employed to investigate the experiences of MSM about accessing healthcare services. In-depth interviews were conducted with 17 MSM aged 18 years and above.Results: Overall, MSM had both negative and positive experiences when accessing healthcare services. However, mainly the negative in the public healthcare facilities, whereas positive were experienced in the private healthcare facilities.Conclusion: The negative experiences of MSM, the judgemental and discriminatory attitudes of healthcare workers towards them and the scarcity or unavailability of resources and healthcare services to address their specific healthcare needs in healthcare facilities have created interpersonal and structural barriers, which prevent MSM from accessing healthcare services.Contribution: These findings suggest the need for the training of healthcare workers to be truly caring, the allocation of resources and healthcare services to addressing MSM-specific healthcare needs in healthcare facilities and the creation of an accommodating environment for them.

Authors: Msomi Ntandoyenkosi L. , Barath Suvishka , Ross Andrew J. 
Published: February 2025

Background: Patient safety incidents (PSIs) cause harm to patients, including falls, accidental ingestion and physical assault. Despite their importance in healthcare, limited information exists on how South African speech-language therapists (SLTs) perceive them in the public and private sectors. This study applied the Donabedian model of patient safety and healthcare quality to SLTs’ perspectives on PSIs.Methods: Free attitude interviews with 10 South African SLTs explored the environment (where and who), processes (how and why) and outcomes (events and consequences) of PSIs. Interviews were transcribed and analysed thematically using a six-phase deductive and inductive approach within the Donabedian model.Results: The Donabedian model’s three components (structure, process, outcome) led to six sub-themes, highlighting its applicability to SLTs’ perspectives on PSIs. It revealed how factors such as clinical environment, care delivery and patient outcomes influence SLTs’ perceptions.Conclusion: Understanding SLTs’ perspectives is essential for addressing environmental issues, developing training, institutional inductions and audits that prevent and manage PSIs, and improving service quality.Contribution: This study emphasises engaging practitioners to understand factors affecting PSIs. It contributes to improving SLT training and practice in South Africa to enhance patient safety.
How and when supervisors’ information sharing reduces new employees’ errors
Authors: Bafa Tesfaye A. , Zhang Mingyu , Chen Chong 
Published: February 2025

Background: Effective supervision through information sharing meaningfully influences employee performance and error reduction. Though the benefits of information sharing are well investigated, its specific impact on new employees’ error reduction in competitive fields, like hotels with various mediators and moderators, is less explored. This research, using the conservation of resources theory, examines how supervisors’ information sharing affects novices’ error reduction, giving attention to the roles of social skills and information seeking.Aim: The study investigates the effect of supervisors’ information sharing on new employees’ error reduction, focusing on how this behaviour, through the moderating effect of social skills and the mediating effect of information seeking, fosters positive affect and reduces errors in the workplace.Setting: The research was conducted among 330 new employee-supervisor dyads at five-star international hotels in Ethiopia.Method: The research is a descriptive and explanatory study using cross-sectional and quantitative methods to analyse data using structural equation modelling.Results: The results indicated that supervisors’ information sharing positively influences error reduction in new employees, enhances positive affect and information seeking and decreases emotional exhaustion.Conclusion: Effective information sharing is crucial for reducing errors and enhancing performance within the hospitality setting, facilitated by the mediation of information-seeking behaviours and the moderation of social skills effects.Contribution: The study has the following theoretical contributions. Firstly, it contributes to a deeper understanding of the importance of supervisors’ information-sharing effects on the behavioural outcomes of new employees during their socialisation stage. Secondly, the study fosters the Conservation of Resources [COR] theory, initially resource gain may not always reveal resource gain in the future as well by looking at the mediating mechanisms between the outcomes of new employees’ error reduction and the supervisor information sharing.
