Quadrant categorization of spillover determinants of sovereign risk of BRICIT nations: a Bayesian approach
Authors: Kumar Pawan , Singh Vipul Kumar 
Published: January 2025

Abstract
This study investigates the determinants that drive the volatility of the credit default swaps (CDS) of BRICIT (Brazil, Russia, India, China, Indonesia, and Turkey) nations as a proxy measure for sovereign risk. On the existence of cointegration, an unrestricted error correction model integrated with the autoregressive distributed lag (ARDL) model is applied to measure the short-run and long-run dynamics empirically. The study utilizes the Bayesian global vector autoregression methodology for cross-border spillover estimation. The study also suggests a strategy for policymakers for quadrant categorization to mitigate risk arising from cross-border spillover. The result of ARDL indicates that the global macroeconomic variables affect the BRICIT CDS more than domestic macroeconomic determinants, with Indian CDS being the most sensitive to Fed tapering. Notably, China’s CDS is the most sensitive to shocks, with the CDS volatility primarily driven by China’s geopolitical risk. Russian CDS is more sensitive to real effective exchange rates due to severe ruble depreciation than crude oil, despite Russia being a major oil exporter. The quadrant categorization indicates that the Indonesian stock market index is most interconnected with BRICIT CDS, while the Turkish long-term interest rates send the highest intensity spillover across BRICIT nations.

Published: January 2025

Abstract

Background
A variety of treatment options for people with alcohol use disorder (AUD) exist. Surveys estimate that 1 in 10 people with AUD utilise treatment, but real-world treatment pathways remain covert. This data-linkage study seeks to characterise treatment utilisation patterns to identify gaps in treatment access and delivery in Germany.

Methods
Linking individual-level data from three sources (statutory health insurance, pension funds, outpatient addiction care services) identified seven alcohol-related treatment types delivered in outpatient (brief psychiatric consultation; formal psychotherapy; pharmacotherapy; low-threshold counselling), inpatient (standard, somatic inpatient treatment; intensive inpatient treatment with somatic and psychosocial care), or either of the two settings (long-term rehabilitation treatment) during 2016–2021. For patients with a new AUD diagnosis (ICD-10: F10.1–9), treatment utilisation over 24 months was recorded and patterns were identified using latent class analyses.

Results
Of n = 9,491 patients with a new AUD diagnosis, 30% utilised at least one alcohol-related treatment type. Treatment utilisation was associated with younger age, female sex, unemployment, German nationality, and lower physical comorbidity. Among treatment entrants, nearly half received only brief psychiatric consultation. A similar share of patients utilised standard or intensive inpatient treatment; the latter occasionally followed by rehabilitation treatment. Formal psychotherapy, low-threshold counselling, and pharmacotherapy were rarely utilised and were mostly used in conjunction with other treatments.

Conclusions
The real-world utilisation of alcohol-related treatments contrasts with existing guidelines, as most patients with diagnosed AUD do not receive adequate care. Structural and social barriers should be minimised to ensure healthcare provision for those affected.

ABSTRACT

Purpose
Red blood cells (RBCs) senescence and blood rheology during ultra-endurance running events appear to be impacted differently depending on the race distance. The physiological mechanisms underlying these differences are poorly understood.

Methods
We investigated the effects of three different ultra-trail running races performed in La Reunion Island (Mascareignes, “the 70 km”, 70 km/4,000 m D+; Trail Du Bourbon, “the 100 km”, 100 km/6,090 m D+; Diagonale des Fous, “the 170 km”, 170 km/10,500 m D+) on RBC oxidative stress, RBC senescence and blood rheology in 66 finishers (18 “70 km”, 24 “100 km”, 24 “170 km”).

Results
We observed a decrease in RBC antioxidant enzyme activities (superoxide dismutase, glutathione peroxidase and catalase) positively related to the race distance, and an increase in RBC H2O2 and isoprostane levels after the three races. However, RBC H2O2 and isoprostane levels were found to be higher after the 70 km compared to the 170 km and the 100 km races. RBC phosphatidylserine externalization increased over baseline value after the 70 km only. Chymotrypsin-like and trypsin-like activities of the RBC proteasome were decreased after all races compared to before. RBC-derived microparticles (RBC-MPs) were increased after the 170 km and the 70 km races. Despite increased RBC senescence markers, RBC deformability increased after the three races. Blood viscosity was differently impacted by the three races with a decrease at low shear rate after the two longest races (the 170 km and the 100 km), and an increase at high shear rate after the shortest one (the 70 km).

Conclusions
Our results confirm that ultra endurance running events differently impact on RBC senescence markers and blood viscosity depending on the race distance, and suggest that RBC oxidative stress could play a key role in the observed alterations.

Improved super-elastic Ti-Ni alloy wire for the angle class III patient with anterior open bite: A case report
Authors: Fan Yu , Yu Jian-Hong , Chen Yuan-Hou 
Published: January 2025

BACKGROUND
Orthodontic treatment for open bite and crossbite cases is always challenging. In this paper, we demonstrate a skeletal class III patient with anterior open bite and crossbite whose problem was successfully corrected with improved super-elastic Ti-Ni alloy wire (ISW).
CASE SUMMARY
A 19 years old male came to our clinic with a chief complaint of anterior open bite and crossbite and not able to chew food well. Clinical examination revealed an angle class III malocclusion with anterior open bite, crossbite and spaced arch. Radiographic and clinical examination showed a skeletal class III pattern. We used ISW to level the upper and lower arch and to correct the anterior open bite and crossbite. Intermaxillary elastics were also used to achieve a better interdigitation. Finally, adequate overbite, overjet and a desirable occlusion were achieved. The active treatment time took 2 years and 2 months.
CONCLUSION
In a case of class III angular malocclusion with open bite and crossbite in the anterior teeth, ideal results were achieved using the ISW technique and the patient was satisfied with the outcome.
Extracorporeal membrane oxygenation combined with intra-aortic balloon counterpulsation for pheochromocytoma: A case report
Authors: Zeng Shu-Ying , Wu Hai-Hui , Yu Zhi-Hong , Zhang Qing-Qian 
Published: January 2025

BACKGROUND
Pheochromocytoma (PHEO) is a type of tumor that originates from chromaffin cells in the adrenal medulla and is classified as an adrenal paraganglioma. PHEOs can secrete catecholamines, leading to a variety of symptoms. Accurate diagnosis and appropriate treatment selection are crucial for favorable outcomes in these cases.
CASE SUMMARY
The patient presented with unexplained chest tightness, palpitations, and pink sputum. Upon examination and analysis of laboratory results, a diagnosis of adrenal PHEO was established. The PHEO secreted high levels of catecholamines, causing sudden fluctuations in blood pressure and heart rate, leading to extremely unstable hemodynamics. Treatment with extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation helped stabilize the patient’s vital signs, allowing for timely surgical intervention.
CONCLUSION
The combination of extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation can enhance tissue perfusion, thus providing a solid foundation for the accurate diagnosis and effective surgical treatment of PHEO.
Stoma occlusion caused by abdominal cocoon after abdominal abscess surgery: A case report
Authors: Xu Rui , Sun Li-Xin , Chen Yan , Ding Chuang , Zhang Ming , Chen Teng-Fei , Kong Ling-Yong 
Published: January 2025

BACKGROUND
Abdominal cocoons (ACs) lack characteristic clinical manifestations and are mainly intestinal obstructions that are difficult to distinguish from intestinal obstruction caused by other causes, resulting in difficult preoperative diagnosis and misdiagnosis and mistreatment. There are no reports of enterostomy occlusion caused by ACs in the literature at home and abroad.
CASE SUMMARY
Here, we report a 16-year-old female patient with intestinal obstruction due to AC. She was treated with abdominal surgery three times. First, she underwent a laparotomy for peritonitis after trauma from a traffic accident. During the procedure, pelvic empyema, severe intestinal adhesions, and damage to the serous layer of the rectum were found, but no significant intestinal rupture and perforation were found. As a precaution, she underwent a prophylactic ileostomy after a flush in her abdomen. The second and third surgeries were for treatment of recurrent stoma obstruction. The patient’s condition was complicated for a long period, but after comprehensive treatment by our department, the patient was successfully discharged from the hospital and is currently recovering well.
CONCLUSION
Currently, abdominal contrast-enhanced computed tomography is the best imaging modality for preoperative evaluation of AC, but most patients are diagnosed only after intraoperative exploration. For the treatment of typical or severe ACs, the primary method of removal and healing of ACs is complete removal of the abdominal fibrous membrane. Finding a breakthrough in the anatomy is the key to the success of the surgery.

Published: January 2025

AimsTrauma & Orthopaedic (T&O) surgery has come under scrutiny for lagging behind other medical specialties in promoting gender and cultural equity and diversity within their workforce. The proportions of female, ethnic minority, and sexual and gender minority individuals within orthopaedic membership bodies are disproportionate to the populations they serve. The aim of this study is to report the findings of a national workforce survey of demographics and working patterns within T&O in Scotland.MethodsA questionnaire devised by a working group was delivered by the Client Analyst and Relationship Development (CARD) group. Utilizing a secure third party ensured anonymity for all respondents. Data were recorded and analyzed by the CARD group.ResultsA total of 353 responses were recorded, representing 71% of the known workforce. Overall, 261 respondents (74%) identified as male, 85 (24%) female, and seven (2%) preferred not to say. For specialist trainee (ST)3 to ST6, 148 (42%) were female, and for ST7 to ST8, 131 (37%) were female. In total, 226 of all respondents (64%) were white-British, 35 (10%) were white-European, and 92 (26%) were of an ethnic minority background. A total of 321 of respondents (91%) identified as heterosexual, 14 (4%) preferred not to say, and 18 (5%) identified as LGBTQ+ or preferred to self-describe.ConclusionThis is the largest national workforce survey in contemporary surgical literature. The findings demonstrate a greater proportion of female surgeons overall compared to other studies in T&O. This proportion of females was highest among more junior trainees. The Scottish T&O workforce is more ethnically diverse than the demographics of the population it serves. This study suggests that T&O in Scotland is an evolving speciality in terms of equality and diversity, and is making positive progress.Cite this article: Bone Jt Open 2025;6(1):103–108.
Ultralow-noise sub-two-cycle pulses at 1600 nm from a compact fiber-feedback optical parametric oscillator system at 76 MHz
Authors: Thannheimer Johann , Alabbadi Abdullah , Steinle Tobias , Giessen Harald 
Published: January 2025

We demonstrate fiber-based self-compression down to sub-two optical cycles (9.5 fs) at 1600 nm with an average power of 620 mW (8.2 nJ) and a repetition rate of 76 MHz. We use an Yb-based pump laser to drive an optical parametric oscillator, which is subsequently amplified to the watt scale using an optical parametric amplifier. The grating-free single stage pulse compression is realized by a 42-mm-long common single mode fiber. The compact system is furthermore shown to be highly stable, shot-noise-limited, and a broadband mid-infrared source through intra-pulse difference frequency generation.

An accident was happened? Conceptual and input biases in the overpassivization of English unaccusative verbs
Authors: Kim Jieun , Han Shinshil , Lee Sang-Ki 
Published: January 2025

Abstract
The overpassivization of unaccusative verbs (e.g., An accident was happened) has been widely observed among second language (L2) learners, regardless of their first languages. In an attempt to determine the effects of cognitive factors on overpassivization, the present study investigated how input frequency, types of alternation (i.e., unaccusatives with and without transitive counterparts), types of causation (i.e., externally and internally caused events), and the interactions among these factors affect L2 learners’ judgments of English unaccusativity. A forced-choice acceptability judgment task (AJT) was administered to 97 Korean EFL learners, utilizing 52 items based on the three factors. According to a multilevel regression model, all those factors and the three-way interaction among them significantly predicted learners’ AJT scores. Specifically, in externally caused event construals, learners demonstrated greater accuracy when exposed to high frequency and non-alternating verbs. Additionally, accurate judgments on alternating unaccusatives were associated with discourse contexts interpreted as internally caused rather than externally caused. These findings highlight the importance of considering the statistical nature of language learning, learners’ learning histories, and potential conceptual biases in explaining L2 English unaccusativity. Overall, the study sheds light on the complex interplay between linguistic input and cognitive factors in L2 acquisition processes.

Published: January 2025

Abstract
The military invasion of Ukraine by the Russian Federation on February 24, 2022, and the further introduction of martial law affected all spheres of Ukrainian society, including the non-profit sector’s activities. As a result, civil society institutions were forced to adapt to new public needs, as well as to emerging security challenges and new regulatory restrictions. In this research note, we examine on one side, how the martial law and previous legislation (and the related societal upheavals) have shaped the new roles and functioning of non-profit organizations in Ukraine and, on the other side, what the challenges to volunteers’ and domestic non-profit organizations’ activities in Ukraine deriving from these regulations and legislations. The identification of these challenges ensues from a survey of the Ukrainian non-profit sector as well as an analysis of Ukrainian regulation, statistical data, and recent scientific papers. Overall, we highlight a key discrepancy between Ukrainians’ concept of charitable activities as well as humanitarian aid and the Western approach to the same concepts and suggest regulatory improvements to address other challenges identified to facilitate philanthropic activities in Ukraine.
Comparison of clinical artificial oocyte activation protocols on mouse egg activation and embryo development

Published: January 2025

In briefArtificial oocyte activation (AOA) with Ca2+ ionophores is a valuable tool in assisted reproduction but may affect cellular events critical for embryo development. This study shows the impact of different AOA protocols on embryonic development efficiency and meiotic progression.AbstractAOA with Ca2+ ionophores is an experimental procedure that benefits patients who fail to obtain fertilized eggs. However, the impact of non-physiological Ca2+ increases on cellular events involved in the egg–embryo transition and early development remains poorly understood. Using the mouse model, this study compares common Ca2+ ionophore protocols applied in clinical practice – one or two exposures to A23187 or a single exposure to ionomycin – focusing on embryonic development and cellular events associated with egg activation. All groups of ionophore-activated eggs exhibit lower levels of first mitotic division compared to those activated by spermatozoa or SrCl2, attributable to variations in Ca2+ dynamics during activation. At the cellular level, these eggs presented defects in spindle morphology and chromosome segregation during meiosis progression, associated with lower levels of cytoplasmic ATP, without changes in reactive oxygen species. These findings highlight the importance of optimizing Ca2+ management in AOA protocols.

Published: January 2025

Проведена оценка состояния нарушенных пожарами, рубками и насекомыми-вредителями участков лесных земель в предгорьях Восточного Саяна в присущих району исследования лесных формациях - кедровой ( Pinus sibirica Du Tour), пихтовой ( Abies sibirica Ledeb.), сосновой ( Pinus sylvestris L.), еловой ( Picea obovata Ledeb.), лиственничной ( Larix sibirica Ledeb.), березовой ( Betula pendula Roth), осиновой ( Populus tremula L.), а также на участках лесных культур. Установлено, что вследствие воздействия пожаров, насекомых-вредителей, рубок и ветровалов происходит ухудшение санитарного состояния лесов. Выявлены закономерности естественного лесовосстановления на нарушенных участках лесных земель. Отмечено, что в результате разрастания густого травяного покрова, образования мощной подстилки, разрастания мха сфагнума ( Sphagnum L.) и возникновения частых пожаров на большей части нарушенных участков лесных земель отмечается неудовлетворительное лесовосстановление. На участках с достаточным количеством жизнеспособного подроста естественное лесовозобновление происходит вегетативным способом мягколиственными малоценными древесными породами (березой и осиной), которые, в свою очередь, угнетают молодое неокрепшее поколение хвойных деревьев (в том числе лесных культур) за счет затенения и конкурентной борьбы за почвенные элементы питания.
An assessment of the state of forest lands disturbed by fires, logging and insects in the foothills of the Eastern Sayan Mountains in the forest formations inherent in the study area (Siberian stone pine ( Pinus sibirica Du Tour), fir ( Abies sibirica Ledeb.), Scots pine ( Pinus sylvestris L.), spruce ( Picea obovata Ledeb.), larch ( Larix sibirica Ledeb.), birch ( Betula pendula Roth), aspen ( Populus tremula L.)) as well as in forest crops was carried out. The impact of fires, insects, logging, and windfalls was found to result in degradation of the forest health conditions of all forest formations within the boundaries of the foothills of the Eastern Sayan Mountains. Characteristics of natural reforestation on disturbed areas of forest lands were revealed. Unsatisfactory reforestation was observed on most of the disturbed areas of forest lands due to proliferation of the dense grass cover, the formation of a thick duff, the growth of sphagnum (Sphagnum L.) and the occurrence of frequent fires. In cases where there is a sufficient amount of healthy regeneration, natural reforestation occurs by vegetative propagation of soft-leaved low-value tree species (birch and aspen), which, in turn, inhibit the young immature generation of coniferous trees (including forest plantations) due to shading and competition for soil nutrients.
