Background
To explore an influence of the COVID-19-related lockdown on ocular axial elongation in school children in Russia.

Methods
The participants of the school-based Ufa Children Myopia Study in Ufa/Russia underwent, at baseline in 2019/2020 before the COVID-19 outbreak and after a COVID-19-related lockdown, a detailed interview and ophthalmological examination including laser interferometric biometry for axial length measurement.

Results
The study included 461 children (age:10.7±2.1 years;range:6.8–16.9 years). The mean follow-up was 1.41±0.33 years. Mean axial length at baseline was 23.96±0.95mm and 23.94±0.95mm in the right and left eyes, respectively. During the study period, annual axial elongation (right/left eyes) was 0.19±0.17mm/0.19±0.22mm. Before the COVID-19 lockdown, the age-dependent coefficient for axial length (ADCAL) for the right/left eyes was 0.21mm (95%CI:0.17,0.25)/0.20mm (95%CI:0.16,0.24). In children younger than 9.6 years (n = 157), annual axial elongation (right eyes) during the study period was larger than the ADCAL before the COVID-19 outbreak (0.29 mm (95%:0.00,0.66) versus 0.21 mm (95%CI:0.02,0.41)). In the groups aged 9.6 to 11.4 years (n = 148) and aged >11.4 years (n = 156), annual axial elongation during the study period was comparable to the ADCAL before the COVID-19 outbreak (0.18mm (95%CI:-0.07,0.46) versus 0.22mm (95%CI:-0.05,0.48), and (0.09mm (95%CI:-0.15,0.34) versus 0.14mm (95%CI:0.00,0.28), respectively). In children aged ≤9 years at study end, axial length at study end was 0.20 mm larger than axial length at baseline in the participants aged ≤9 years at baseline. Larger axial elongation during the study period was associated (multivariable analysis) with younger age (beta:-0.62;P<0.001), female sex (beta:0.21;P<0.001), longer study period (beta:0.22;P<0.001), and longer axial length at baseline (beta:0.28;P<0.001), and marginally, with less time spent outdoors (beta:-0.07;P = 0.06).

Conclusions
The COVID-19-related lockdown in the Russian city of Ufa was associated with a relatively minor increase in axial elongation, detected only in children aged <9.6 years.

Background
Smartphone and social media use are supposed to be integral parts of university students’ daily lives. More specifically, smartphones and social media are frequently used for communication in daily life during the COVID-19 pandemic. Nonetheless, uninterrupted and persistent use of these technologies may lead to several psychological problems. Even though smartphones and social media were used more frequently during the pandemic, there is no evidence suggesting that the studies were not undertaken in low-income countries, including Ethiopia. Therefore, the current study aimed to assess problematic smartphone use and social media use among undergraduate university students in southern Ethiopia.

Methods
A cross-sectional study was carried out among 1,232 university students using a simple random sampling technique. The Bergen Social Media Addiction Scale and Smartphone Application-Based Addiction Scale were used to collect data on social media and smartphone use, respectively. The Beck Depression Inventory, Generalized Anxiety Assessment Tool, Rosenberg Self-Esteem Scale, and Pittsburg Sleep Quality Index were standardized tools used to measure other independent variables. To identify factors, simple and multiple linear regression analyses were performed. A p-value of 0.05 was used to determine statistical significance.

Results
The overall response rate was 95%. The mean scores for problematic smartphone and problematic social media use were 17 ± 3.3/36 and 12.7 ± 2.2/30, respectively. A linear regression model revealed that being female, first-year students and poor sleep quality were significantly associated with problematic smartphone use. Factors associated with problematic social media use (PSMU) were depression, substance use, and urban residence.

Conclusions
This study identified significant problems with smartphone and social media use among university students. Therefore, it is preferable to provide psychological counselling, educate students about safe, beneficial, and healthy internet use, and focus on recognized high-risk groups in order to give them special attention. It is also preferable to seek counselling about substance use. It is preferable to regularly screen and treat individuals with psychological problems in collaboration with stakeholders.
Relationship between age at menarche and metabolic diseases in Korean postmenopausal women: The Korea National Health and Nutrition Examination Survey 2016–2018
Authors: Jung Hyein , Sung Yeon-Ah , Hong Young Sun , Song Do Kyeong , Hong So-hyeon , Lee Hyejin 
Published: January 2023

Background
Cardiovascular disease is the leading cause of morbidity and mortality in postmenopausal women. Early menarche may be associated with an increased risk of metabolic diseases such as diabetes and cardiovascular disease. This study aimed to investigate the effect of menarche age and the risk of diabetes and metabolic syndrome in Korean postmenopausal women.

Methods
We analyzed 4,933 postmenopausal women (mean age: 64.7 years) using the Korean National Health and Nutritional Examination Survey 2016–2018. Subjects were divided into three groups according to menarche age (early menarche: ≤ 12 years (n = 451), reference: 13–16 years (n = 3,421), and late menarche: ≥ 17 years (n = 1,061)). Logistic regression analysis was used to estimate the odds ratio (OR) for diabetes and metabolic syndrome.

Results
Women with an early menarche age were younger, more educated, and had higher income than the other groups (p-value < 0.001). There were no differences in body mass index, blood pressure, fasting glucose, HbA1c, and cholesterol levels among the three groups. After adjusting for potential confounding factors, early menarche age was significantly associated with the risk of diabetes (OR 1.435, 95% confidence interval (CI): 1.069–1.928). The prevalence of metabolic syndrome in all subjects was 41.1%. After adjusting for potential confounding factors, the OR of metabolic syndrome in the early menarche group was 1.213 (95% CI: 0.971–1.515)

Conclusion
The risk of diabetes was 1.43 times higher in postmenopausal Korean women with early menarche. Although the risk of metabolic syndrome was not statistically significant, it showed a tendency to increase in the early menarche group. Our results suggest that age at menarche may be helpful in diabetes risk stratification and early interventions for postmenopausal women.

Maxillary Sinus Pathology and its Relationship with Pathology and Dental Treatments. Systematic Review
Authors: Areizaga-Madina María , Pardal-Peláez Beatriz , Montero Javier 
Published: January 2023

Introduction and objective: The aim of this review is to evaluate to what extent sinus pathology originates from dental pathology or treatment, and to assess the occurrence frequency of sinus pathology in its different forms using cone beam computed tomography (CBCT).
Method: The literature review was conducted using PubMed, Scopus and the Cochrane Library. Forty-two articles were included (25 case series, ten cross- sectional studies, three case-control studies, two cohort studies, one prospective study, and one retrospective study).
Results: Forty-two articles involving a total of 13,191 patients and 17,374 CBCTs were included in this review. The most frequent pathological findings were, by a considerable degree, inflammatory diseases, which represented 75.16% of the total findings, followed by infection (12.13%), tumours (6.88%), and high pneumatisation (2.07%). Within dental pathology, there is a direct Pearson correlation with polyps (1) and opacification (0.999), and an almost direct correlation with retention cysts (0.981) and sinus-associated dental elements (0.972).
Conclusions: Our results further support the argument that dental modifications and treatments are an important cause of sinus pathology. For this reason, dental aetiologies must be taken into account by both dentists, maxillofacial surgeons and ENT when considering the most appropriate treatment for patients with maxillary sinusitis.
Sex‐moderated relationship between the 2D:4D ratio and circulating hormones in an adult Ghanaian population
Authors: Banyeh Moses , Appiah Samuel Kwasi , Abubakari Abdul‐Malawi , Issah Musah , Amidu Nafiu 
Published: January 2023

AbstractThe second‐to‐fourth digit ratio (2D:4D) is the putative marker of prenatal hormone exposure. The 2D:4D ratio or the right–left difference (Dr‐l) are said to be negative and positive correlates, respectively, of circulating testosterone and estrogen in both adult males and females. However, previous studies on the subject have reported mixed results. This study aimed to determine the sex‐moderated relationship between the 2D:4D ratio and adult circulating testosterone, estradiol, testosterone‐to‐estradiol ratio and the free androgen index. This was a cross‐sectional study from January to June 2021 at the University for Development Studies, Ghana. The study involved 62 participants (Female = 28; Male = 34), aged between 20 and 26 years. The right (2D:4DR), the left (2D:4DL), and their difference (Dr‐l) were measured by computer‐assisted analysis. Fasting venous samples were assayed for total testosterone (T), estradiol (E2), and sex hormone‐binding globulin (SHBG) using ELISA. The free androgen index (FAI) was then calculated (T/SHBG) and the data were analyzed using moderated and/or weighted regression. Males had significantly higher T and FAI than females while females had significantly higher E2 than males, which were independent of age and body mass index (p < 0.001). There was a significant SEX*Dr‐l interaction on FAI (p = 0.007). The Dr‐l correlated negatively with FAI in males but positively in females and accounted for about 94.0% of the variability of FAI in males (adjR2 = 0.940) and only 0.2% in females (adjR2 = 0.002). The 2D:4D ratio, a putative marker of prenatal hormone exposure, may have an impact on sex differences in adult free androgen index.

Published: January 2023

Abstract
In accordance with all the most recent international guidelines, the variation of circulating levels of cardiac troponins I and T, measured with high-sensitivity methods (hs-cTnI and hs-cTnT), should be used for the detection of acute myocardial injury. Recent experimental and clinical evidences have demonstrated that the evaluation of hs-cTnI and hs-cTnT variations is particularly relevant: a) for the differential diagnosis of Acute Coronary Syndromes (ACS) in patients admitted to the Emergency Department (ED); b) for the evaluation of cardiovascular risk in patients undergoing major cardiac or non-cardiac surgery, and in asymptomatic subjects of the general population aged >55 years and with co-morbidities; c) for the evaluation of cardiotoxicity caused by administration of some chemotherapy drugs in patients with malignant tumors. The aim of this document is to discuss the fundamental statistical and biological considerations on the intraindividual variability of hs-cTnI and hs-cTnT over time in the same individual. Firstly, it will be discussed in detail as the variations of circulating levels strictly depend not only on the analytical error of the method used but also on the intra-individual variability of the biomarker. Afterwards, the pathophysiological interpretation and the clinical relevance of the determination of the variability of the hs-cTnI and hs-cTnT values ​​ in patients with specific clinical conditions are discussed. Finally, the evaluation over time of the variation in circulating levels of hs-cTnI and hs-cTnT is proposed for a more accurate estimation of cardiovascular risk in asymptomatic subjects from the general population.
Rapid-onset obesity, hypothalamic dysfunction, hypoventilation, and autonomic dysregulation syndrome – neuro-endocrine tumours (ROHHAD-NET): case series and learning points

Published: January 2023

Abstract

Objectives
Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, autonomic dysregulation (ROHHAD) is a rare syndrome associated with high morbidity and mortality. Diagnosis is often challenging. We describe three cases of ROHHAD with heterogeneous presentations but some consistent clinical features, including hyperprolactinaemia at diagnosis. We highlight when the diagnosis of ROHHAD should be considered at an early stage.

Case presentation
All three patients presented between 4 and 6 years old with rapid-onset obesity. They all have central hypoventilation requiring nocturnal BiPAP, varying degrees of hypothalamic dysfunction with hyperprolactinaemia being a consistent feature, and autonomic dysfunction. One patient has a neuro-endocrine tumour (NET) and two have glucose dysregulation.

Conclusions
High prolactin was a consistent early feature. Central hypoventilation and NET may present later and therefore regular sleep studies and screening for NETs are required. A high suspicion of ROHHAD is warranted in patients with rapid, early-onset obesity and hyperprolactinaemia without structural pituitary abnormality.
Preparation of CdS–Ag2S nanocomposites by ultrasound-assisted UV photolysis treatment and its visible light photocatalysis activity

Published: January 2023

Abstract
Thiosulfate is a green leaching agent used in the hydrometallurgical process because it is both environmentally benign and can form the required soluble ion complexes. In this article, a novel method for the synthesis of CdS–Ag2S nanocomposites from a solution of relevant ion complexes via ultrasound-assisted ultraviolet (UV) photolysis was proposed. An analysis of the mechanism revealed that the complexes undergo a series of photochemical reactions. The CdS–Ag2S nanocomposites were synthesized by photochemical co-precipitation under UV-C irradiation. The microstructure, chemical composition, optical and electrochemical properties of the prepared nanocomposites were analyzed to verify the synthesis and investigate the product. The photodegradation of methyl orange (MO) under a xenon lamp was performed to determine the photocatalytic activity. Under visible light irradiation, the CdS–Ag2S nanocomposites undergo the electrons transition (from valence band to conduction band) to form photogenerated electron–hole pairs realizing the effective separation of carriers and finally promote the degradation of MO to water and carbon dioxide. The subsequent degradation efficiency of the CdS–Ag2S nanocomposites was found to be 87% after 90 min, and it was larger than 78% for pure CdS prepared via UV photolysis, indicating that the as-developed novel method can effectively fabricate CdS–Ag2S photocatalyst with superior performance.
Restrictions on past-tense passives in Late Modern Danish
Authors: Gregersen Sune 
Published: January 2023

AbstractThis article investigates a case of lexical restrictions on a voice construction, specifically Danish past-tense passives. Present-Day Danish has both a periphrastic and an inflectional passive construction, but in the past tense, most ablaut (strong) verbs cannot form the inflectional passive (e.g.∗\astskreves‘was written’,∗\astbares‘was carried’). Various explanations for these restrictions have been proposed in the literature, but their historical background has not been investigated in any detail. This article focusses on the passive restrictions in Late Modern Danish, using various sources mainly from the eighteenth and nineteenth centuries. It is shown that while lexical restrictions on the past-tenses-passive are already mentioned in eighteenth and nineteenth-century grammars, the grammaticality of the individual forms has changed; for instance, the now obsolete formskreves‘was written’ is attested in several Late Modern Danish sources. Furthermore, the primary sources differ greatly with respect to their use of the passive in the past tense. I suggest that sociolinguistic variables, such as level of education and formality of the texts, must be taken into account when trying to explain the development of the Danish passive, and that the lexical restrictions on past-tenses-passives may in fact be a side effect of standardization in the eighteenth and nineteenth centuries.
Interpreting unwillingness to speak L2 English by Japanese EFL learners
Authors: Muroya Akiko 
Published: January 2023

Abstract
This article reports on an empirical study investigating what makes Japanese learners of English as a foreign language (EFL) unwilling to speak English, regardless of their learning period, proficiency level, and location of the communication. The current study focuses on the self-perception of second language (L2) English abilities, anxiety, and interlocutors as possible causes of their unwillingness to speak L2 English, compared with first language (L1) Japanese. An online questionnaire was administered to 27 Japanese undergraduate students (age: 19–22) with non-English majors at a national university in Tokyo, Japan. The results show that the elements depressing the self-perception and willingness to speak are fundamental to managing human relationships in speaking situations, which have more impact on L2 English than L1 Japanese contexts. This is attributable to other-directedness, which has been discussed as being characteristic of Japanese and Chinese EFL learners. Furthermore, it appears plausible to assume that the other-directedness derives more from “considerations for others” than “face-saving.” Future work will further investigate what constitutes Japanese other-directedness, compared with Chinese EFL learners’.

Published: January 2023

Abstract
This paper investigated anti-icing behavior and wettability of droplets on superhydrophobic polymercoatings between lotus effect and petal effect, which were prepared on surfaces of 2021 aluminum alloy with 1H, 1H, 2H, 2H-heptafluorodecyl (FAS-17). The prepared surfaces displayed excellent hydrophobicity with contact angles of 154.9° ± 1.5°and 139.8° ± 1.3°, while rolling angles are 4° ± 1.0° (lotus effect) and 30° ± 1.5° (petal effect). Thus, the present study focused on the different characterizations and the anti-icing potential of the superhydrophobic polymersurfaces were analyzed based on three parameters including the icing delay time, the crystallization temperature of water droplets, and contact time of impinging droplets on the cold superhydrophobic polymer coatings (−15 °C). Furthermore, the anti-icing of superhydrophobic coatings between lotus effect and petal effect with freezing time and crystallization temperature experimental phenomena were consistent with the thermodynamic analysis. It is also proved that the droplets have different bounce behavior on different polymercoating surfaces by droplet impact experiment. The study offers a comprehensive perspective on polymercoatings of different wetttablility for anti-icing behavior applications.

Abstract
Bishop, C, de Keijzer, KL, Turner, AN, and Beato, M. Measuring interlimb asymmetry for strength and power: A brief review of assessment methods, data analysis, current evidence, and practical recommendations. J Strength Cond Res 37(3): 745–750, 2023—The aim of this brief narrative review is to summarize the present evidence, provide recommendations for data analysis, and provide appropriate training methods to reduce strength and power asymmetries within athlete populations. Present evidence shows that a strong interest in the assessment of asymmetry exists. Despite the perceived associated relationship between asymmetry and injury and performance, a clear link is still missing. Practitioners need to be aware of this when they decide to assess asymmetries and later design training interventions. Several bilateral and unilateral tests could be used to assess asymmetries, such as isokinetic dynamometry, the isometric mid-thigh pull, squat, and Nordic hamstring exercise. Based on the current evidence, future investigations require further standardization of methodology and analysis to optimize interpretation (e.g., within session and between session), adoption, and implementation of interlimb asymmetry testing and appropriate interventions. In this review, 3 training interventions have been proposed to reduce existing lower limb asymmetries in sport populations: traditional resistance training, flywheel resistance training, and combined training interventions, with some evidence suggesting that such interventions can reduce lower limb asymmetries. Nonetheless, the number and quality of articles currently available are too limited to draw firm conclusions; therefore, further research is needed to verify whether training interventions can achieve these aims. To develop an understanding and application of interventions addressing interlimb asymmetries within the sport, greater methodological rigor should be applied toward study design, data analysis, and interpretation of future investigations and when appraising the current literature.
