Although over 180 freshwater fish species have been reported from Nepal, little is known of their ecology and distribution. This information is needed because their diversity may be threatened by developments like hydropower constructions. We conducted Nepal’s first environmental DNA (eDNA) based fish biodiversity assessment in two major river systems- Karnali River (KR), which is still pristine and Trishuli River (TR) with numerous hydropower plants. The eDNA was concentrated by filtering (0.45 μm pore size) two liters of water collected at different sampling points in each study site. A total of 224 eDNA samples (KR=162 and TR= 62) were collected, from which fish species was identified by 12S rRNA metabarcording approach utilizing Illumina sequencing platform. Alpha and beta diversity of species between two sites were compared. Also, in KR site, fish (N=795) were caught, and identified using COI based DNA barcoding- building Nepal’s first fish DNA reference database. Field sampling identified 21 species through morphology and DNA barcoding, where Barilius spp. and Schizothorax spp. were the most abundant. From 244 eDNA samples, 24 Operational Taxonomic Units (OTUs) were identified in TR and 46 in KR with 19 being common to both sites, 27 being unique in KR, and five in TR only. Most fishes were of Cypriniformes and Siluriformes orders, with Barilius spp. and Schizothorax spp. being the most abundant. Long distance migratory fish (Tor spp, Neolissochilus hexagonolepis) and non-native fish (Cyprinus carpio, Hypophthalmichthys molitrix, Gymnocorymbuster netzi, Ctenopharyngo donidella, Clarias gariepinus) were identified in eDNA samples as well. Alpha diversity in TR was significantly lower than in KR. High beta diversity between the two sites indicated low similarity in fish diversity between the TR and KR. This study demonstrated the utility of eDNA as a non-invasive technique for biodiversity assessment which is particularly useful in areas like Nepal with scarce data on fish species distribution.
Population-level transitions in observed difficulties through childhood and adolescence

Published: February 2023

In an attempt to better characterise the complexity of difficulties observed within developing populations, numerous data-driven techniques have been applied to large, mixed datasets. However, many have failed to incorporate the core role of developmental time in these approaches. That is, the typical course of change in behavioural features that occurs over childhood to adolescence. In this study, we utilised manifold projections alongside a gradient boosting model on data collected from the Millennium Cohort Study to unpack the central role developmental time in how behavioural difficulties transition between the ages of 5, 11 and 17. Our analysis highlights numerous observations: (i) girls develop relatively greater internalised behavioural problems during adolescence, (ii) in the case of a chaotic home environment, co-occurring internalizing and externalizing difficulties tend to persist during childhood, (iii) peer problems were the most likely to persist over the whole 12 year-period (especially in the presence of early maternal depression and poor family relationships), and (iv) there were two pathways with distinct risk factors leading to antisocial behaviours in adolescence – an early childhood-onset pathway and later adolescent-onset pathway. Our findings provide evidence that investigations of child and adolescent difficulties must be open to the possibility of multiple sub-groups, and variability in trajectory over time. We further highlight the crucial role of family and social support, and school experience-related factors, in predicting children’s outcomes.
Insight in non-participation and drop-out among coronary artery disease patients in a prospective cohort study – the THORESCI study
Authors: Kupper Nina , van Montfort Eveline , Denollet Johan , Widdershoven Jow
Published: February 2023

Background: Non-random study non-participation and loss to follow-up are problematic in most cohort studies, and frequently impair data quality and representativeness. The current study examined demographic, disease-related and psychological correlates of patient non-participation (“refusers”), and loss to follow-up (“drop-outs”) in a large cohort of patients with coronary artery disease. We also examined whether, in comparison to participants, refusers and drop-outs differed in their likelihood to start cardiac rehabilitation and their survival status. Method: Participants who dropped out (n=376; mean age=67.5±122; 70% men), and refusers (n=148; mean age=71.8±12.6; 69% men) were compared with active participants (n=865; mean age=65.1±11.8; 79% men). Demographics, clinical risk factors, medical history, participation to cardiac rehabilitation (CR), and mortality were obtained from patients’ medical records and baseline questionnaires. Information about psychological symptoms (GAD-7, PHQ-9, DS14) was derived from medical records for patients who started CR in hospital. For patients who did not participate to CR but who participated in the study, psychological data were completed with study questionnaire data. Results: Compared to participants, refusers were older (OR= 1.04; 95% CI: 1.02-1.07; p = .002), had a lower socio-economic status (OR= 2.78; 95% CI: 1.52-5.07; p = .001) were more often smokers (OR= 1.64; 95% CI: 1.04-2.58; p = .03), and experienced a larger burden of illness (cardiac history: OR= 1.56; 95% CI: 1.03-2.37; p = .04; non-cardiac history: OR= 1.97; 95% CI: 1.24-3.13; p = .004). Refusers also participated less often in CR, independent of age and sex (OR= .69; 95% CI: .48-.99, p = .04). They also showed increased mortality as compared to patients who initially decided to participate (10% vs. 5%; OR= 2.09; 95% CI: 1.14-3.85, p = .02). Compared to participants, drop-outs were more often women (OR= 1.48; 1.08-2.03, p = .02). In drop-outs, increased levels of smoking (OR = 1.51; 1.13-2.02, p = .01), and a larger burden of illness were found (non-cardiac history: OR= 1.31; 95% CI: 1.00-1.71; p = .05). We did not find any differences between the groups regarding psychological symptoms.Conclusion: Refusers and drop-outs differed systematically on some demographics and disease-related factors, which was translated into poorer health outcomes, as there were differences in the mortality risk of refusers versus participants. Therefore, we conclude that results from survey studies examining the association between psychosocial factors and health outcomes may underestimate the effects, as a healthier sample is participating than is present in the real life population.
Individual differences in emotion prediction and implications for social success
Authors: Barrick Elyssa M , Thornton Mark Allen , Zhao Zidong , Tamir Diana
Published: February 2023

The social world requires people to predict others’ thoughts, feelings, and actions. People who successfully predict others’ emotions experience significant social advantages. What makes a person good at predicting emotions? To predict others’ future emotional states, a person must know how one emotion transitions to the next. People learn how emotions transition from at least two sources: (i) internal information, or one’s own emotion experiences, and (ii) external information, such as the social cues detected in a person’s face. Across five studies, we find evidence that both sources of information are related to accurate emotion prediction: individuals with atypical personal emotion transitions, difficulty understanding their own emotional experiences, and impaired emotion perception displayed impaired emotion prediction. This ability to predict others’ emotions has real-world social implications. Individuals who make accurate emotion predictions have better relationships with their friends and communities and experience less loneliness. In contrast, disruptions in both internal and external information sources explain prediction inaccuracy in individuals with social difficulties, specifically with social communication difficulties common in autism spectrum disorder. These findings provide evidence that successful emotion prediction, which relies on the perception of accurate internal and external data about how emotions transition, may be key to social success.

Published: February 2023

To establish the dependence of the impact of weight training on the manifestation of physical qualities of schoolchildren in grades 9-11. The research was conducted at the Pokrovsky-Bagachan Lyceum of the Khorolsk City Council of the Lubensk District of the Poltava Region. To solve the problem, a group of 30 high school students was formed, who systematically practiced in the strength sports section, and in particular, kettlebell sports. The age of the test subjects was 15-17 years, the experience of continuous training in kettlebell sports sections was 0.5-1.5 years. Pedagogical testing is presented to determine the level of special preparedness of schoolchildren of grades 9-11, who were engaged in kettlebell sports sections. Exercises were determined that are appropriate to use at these stages of training: jerking a 24 kg kettlebell in 10 minutes; kettlebell push 24 kg in 10 minutes; squats with weights of 24 kg for the number of times; deadlift with weights 24 kg for the number of times. The material presented in this publication shows that the general physical fitness of schoolchildren of grades 9- 11, who train in sports sections of secondary schools, corresponds to peers in most indicators, but has more improved indicators. The mentioned facts testify to the slowing down of the processes of deceleration of the physical development of modern children. As a result of testing of special preparedness using competitive and special-preparatory exercises for kettlebell sports, it was found that the indicators improve every year in all exercises (p<0.05), especially in the 24 kg kettlebell jerk in 10 minutes from the 9th to the 10th grade (t=4.00; p<0.001), and from 10th to 11th grade (3.55; p<0.01), but the high increase was in two years (t=7.05; p<0.001). In performing the 24 kg kettlebell push exercise, the number of times was from 9th to 10th grade (t=2.56; p<0.05), and from 10th to 11th grade (2.79; p<0.05), but high the increase was in two years (t=4.79; p<0.001). Performance of the squat exercise with 24 kg weights increased by the number of times in the age intervals from the 9th to the 10th grade (1.78; p>0.05), from the 10th to the 11th grade (t=2.10; p<0.05) , and for the entire training period (t=3.66; p<0.001). The indicators of deadlift with 24 kg weights per number of times among schoolchildren significantly increased in the period from the 9th to the 10th grade (t=2.77; p<0.05) from the 10th to the 11th grade (t=3.15; p<0, 01), and for the entire period was (t=7.48; p<0.001).

Authors: Rebryna A.
Published: February 2023

The components that motivate students to participate in physical education have been studied. The priority directions for the formation of a healthy lifestyle in the process of education have been determined. It has been established that health is a natural and absolute vital value, which occupies the top rank in the hierarchy of human values, as well as in the system of such categories of human existence as interests and ideals, harmony, beauty, meaning and happiness of life, creative work, program and rhythm of life. It has been proven that the attitude to health includes a person's self-assessment of his physical and mental state, which is a kind of indicator and regulator of his behavior.

A decrease in the level of health and physical capacity of students is a consequence of significant psycho-emotional stress, violations of the hygienic justification of the daily routine and nutrition. To form an attitude to health as the most important value, to give the knowledge of valeology necessary for the life of each individual, to teach to follow a healthy lifestyle - the main task of modern physical education.

Therefore, the formation of a broad worldview of culture, a careful attitude to one's own health as important components of a lifestyle is decisive in achieving career and life success of modern youth. The problem of forming a healthy lifestyle of modern youth is one of the most urgent, the solution of which determines the future of the state and the further existence of a healthy nation.

OBJECTIVE

The risk of cerebrospinal fluid (CSF) leakage after cranial surgery and its associated complications in children are unclear because of variable definitions and the lack of multicenter studies. In this study, the authors aimed to establish the incidence of CSF leakage after intradural cranial surgery in the pediatric population. In addition, they evaluated potential risk factors and complications related to CSF leakage in the pediatric population.

METHODS

The authors performed an international multicenter retrospective cohort study in three tertiary neurosurgical referral centers. Included were all patients aged 18 years or younger who had undergone cranial surgery to reach the subdural space during the period between 2015 and 2021. Patients who died or were lost to follow-up within 6 weeks after surgery were excluded. The primary outcome measure was the incidence of CSF leakage, defined as leakage through the skin, within 6 weeks after surgery. Univariable and multivariable logistic regression analyses were performed to identify risk factors for and complications related to CSF leakage.

RESULTS

In total, 759 procedures were identified, performed in 687 individual patients. The incidence of CSF leakage was 7.5% (95% CI 5.7%–9.6%). In the multivariate model, independent risk factors for CSF leakage were hydrocephalus (OR 4.5, 95% CI 2.2–8.9) and craniectomy (OR 7.6, 95% CI 3.0–19.5). Patients with CSF leakage had higher odds of pseudomeningocele (5.7, 95% CI 3.0–10.8), meningitis (21.1, 95% CI 9.5–46.8), and surgical site infection (7.4, 95% CI 2.6–20.8) than patients without leakage.

CONCLUSIONS

CSF leakage risk in children after cranial surgery, which is comparable to the risk reported in adults, is an event of major concern and has a serious clinical impact.

Authors: Mansoor Nadia , Gulati Sasha , Fredriksli Oddrun A. , Salvesen Øyvind , Solheim Ole
Published: February 2023

OBJECTIVE

Indications for surgical treatment of hydrocephalus (HC) can vary across centers. The authors sought to investigate the frequencies of surgically treated HC disorders and to study variations in the practice of shunt surgery in Norway, a country with universal and free healthcare.

METHODS

This is a nationwide registry–based study using data from the Norwegian Patient Registry. Four neurosurgical centers serve exclusively in 4 defined geographic regions. All patients who underwent shunt surgery in Norway between January 1, 2008, and December 31, 2021, were included and regional differences and time trends were explored.

RESULTS

The national annual rate of shunt surgery in the study period was 6.0 per 100,000. A total of 4139 individuals (49.5% male) underwent primary shunt surgeries, and a total of 9262 operations including revision surgeries were performed. There were statistically significant regional differences between the 4 treating centers in Norway in terms of patients’ age (median 61 years, range 53–65 years); mean annual rate of primary shunt surgery (5.1–7.6 per 100,000); annual rate of primary shunt surgery in patients of different age groups (0.9–1.2 in 0–17 years, 1.8–2.7 in 18–64 years, and 1.6–3.9 in ≥ 65 years); annual rate of revision surgeries (2.4–5.7 per 100,000); annual rate of primary surgery for communicating HC (0.7–2.0 per 100,000); annual rate of primary surgery for normal pressure HC (0.5–1.8 per 100,000); and annual rate of primary surgery for HC associated with cerebrovascular disease (0.5–2.0 per 100,000). There was significant variation in overall shunt surgeries during the study period (p = 0.026), and there was an overall decrease in revision surgeries over time (p < 0.001). There appears to be a homogenization of revision surgeries over time.

CONCLUSIONS

There are significant and large practice variations in the surgical management of HC in Norway. There are significant differences between regions, particularly in terms of rates of shunt surgery for some diagnoses (communicating HC, normal pressure HC, and HC associated with cerebrovascular disease) as well as revision rates.

OBJECTIVE

Proton beam therapy (PBT) is an increasingly used treatment modality for pediatric patients with brain tumors. Moyamoya syndrome (MMS) is well recognized as a complication of traditional photon radiotherapy, however its association with PBT is less well described. The authors discuss their initial experience with the neurosurgical management of MMS secondary to PBT in a large-volume pediatric neurovascular service.

METHODS

The authors performed a retrospective case review of consecutive children referred for neurosurgical management of MMS after PBT between 2009 and 2022. Patient demographic characteristics, oncological history and treatment, interval between PBT and MMS diagnosis, and MMS management were recorded. Clinical outcome at last review was classified as good if the modified Rankin Scale (mRS) score was ≤ 2 and/or the patient attended mainstream education without additional assistance. Poor outcome was defined as mRS score ≥ 3 and/or the patient received additional educational support. The recorded radiological outcomes included angiographic analysis of stenosis, evidence of brain ischemia/infarction on MRI, and postsurgical angiographic revascularization.

RESULTS

Ten patients were identified. Oncological diagnosis included craniopharyngioma (n = 6), optic pathway glioma (1), ependymoma (1), Ewing sarcoma (1), and rhabdosarcoma (1). The median (interquartile range [IQR]) age at PBT was 5.1 (2.7–7.9) years. The median (IQR) age at MMS diagnosis was 7.8 (5.7–9.3) years. The median time between PBT and diagnosis of MMS was 20 (15–41) months. Six patients had poor functional status after initial oncological treatment and prior to diagnosis of MMS. All 10 patients had endocrine dysfunction, 8 had visual impairment, and 4 had behavioral issues prior to MMS diagnosis. Four patients had a perioperative ischemic event: 2 after tumor surgery, 1 after MMS surgical revascularization, and 1 after receiving a general anesthetic for an MRI scan during oncological surveillance. Seven children were treated with surgical revascularization, whereas 3 were managed medically. The incidence of ischemic events per cerebral hemisphere was reduced after surgical revascularization: only 1 patient of 7 had an ischemic event during the follow-up period after surgery. No children moved from good to poor functional status after MMS diagnosis.

CONCLUSIONS

MMS can occur after PBT. Magnetic resonance angiography sequences should be included in surveillance MRI scans to screen for MMS, and families should be counseled about this complication. Management at a high-volume pediatric neurovascular center, including selective use of revascularization surgery, appears to maintain functional status in these children.
„Kontrola osobista i przeglądanie zawartości bagażu” (art. 15 ust. 1 pkt 5 ustawy o Policji) a ochrona konstytucyjnych praw człowieka
Authors: Taracha Adam

The paper is devoted to the activity defined as ‘personal search and luggage security search’ carried out as part of non-trial operation of law enforcement authorities (on the basis of Article 15(1)(5) of the Police Act). The author discusses the evolution of this activity, which was introduced into the Polish legal system in 1983, mainly to facilitate the fight against democratic opposition. This procedure, which in essence did not differ much from the search activities carried out under the Code of Criminal Procedure, obviously infringed civil rights and freedoms, because it was not accompanied by the provisions containing guarantees, which the Code did contain. The law changed considerably only after amendments to legislative instruments relating to the police, introduced on 14 December 2018. The author believes that the existing regulations provide adequate human rights protection, but are too detailed, which may in practice make the operation of law enforcement agencies less efficient. The author points out to the need for maintaining a balance between guaranteeing civil rights and enabling the law enforcement agencies to discharge their statutory duties connected with ensuring public security and order.
Przywilej morski w Polsce w okresie międzywojennym na tle porównawczym
Authors: Dworas-Kulik Judyta
Published: February 2023

Rozwój transportu morskiego na przeł. XIX i XX w. przyczynił się do międzynarodowej unifikacji prawa morskiego w zakresie przywilejów na statku i hipoteki morskiej. Potrzeba ujednolicenia przepisów wynikała z konieczności realnego zapewnienia wierzycielom zaspokojenia ich roszczeń, bowiem różnorodność przepisów poszczególnych państw, szczególnie ilość przywilejów morskich, która powstała pod rządem różnych systemów prawnych oraz hierarchia ich stosowania ograniczały znaczenie instytucji hipoteki morskiej. Treść przepisów międzynarodowych stała się podstawą do kształtowania polskich przepisów 76 dotyczących wyżej wskazanych instytucji prawa morskiego. Te jednakże powstały dopiero z początkiem lat 60-tych XX w., stąd też bogata literatura przedmiotu dotyczy głównie okresu z przeł. XX i XXI w. Problematyka instytucji przywileju morskiego w okresie dwudziestolecia międzywojennego była dotąd jedynie sygnalizowana w literaturze przedmiotu, dlatego też niniejsza publikacja ma na celu kompleksowe omówienie zagadnienia.

Background:

Cognitive postscripts of COVID-19, codenamed as ‘cognitive COVID’ or ‘brain fog,’ characterized by multidomain cognitive impairments, are now being reckoned as the most devastating sequelae of COVID-19. However, the impact on the already demented brain has not been studied.

Objective:

We aimed to assess the cognitive functioning and neuroimaging following SARS-CoV-2 infection in patients with pre-existing dementia.

Methods:

Fourteen COVID-19 survivors with pre-existing dementia (four with Alzheimer’s disease, five with vascular dementia, three with Parkinson’s disease dementia, and two with the behavioral variant of frontotemporal dementia) were recruited. All these patients had detailed cognitive and neuroimaging evaluations within three months before suffering from COVID-19 and one year later.

Results:

Of the 14 patients, ten required hospitalization. All developed or increased white matter hyperintensities that mimicked multiple sclerosis and small vessel disease. There was a significant increase in fatigue ( p = 0.001) and depression ( p = 0.016) scores following COVID-19. The mean Frontal Assessment Battery (p < 0.001) and Addenbrooke’s Cognitive Examination ( p = 0.001) scores also significantly worsened.

Conclusion:

The rapid progression of dementia, the addition of further impairments/deterioration of cognitive abilities, and the increase or new appearance of white matter lesion burden suggest that previously compromised brains have little defense to withstand a new insult (i.e., ‘second hit’ like infection/dysregulated immune response, and inflammation). ‘Brain fog’ is an ambiguous terminology without specific attribution to the spectrum of post-COVID-19 cognitive sequelae. We propose a new codename, i.e. ‘FADE-IN MEMORY’ (i.e., Fatigue, decreased Fluency, Attention deficit, Depression, Executive dysfunction, slowed INformation processing speed, and subcortical MEMORY impairment).
Creutzfeldt-Jakob Disease in a Patient with Previous COVID-19 Infection: “The Virus Caused the Derangement in My Brain”
Authors: Leccese Deborah , Cornacchini Sara , Nacmias Benedetta , Sorbi Sandro , Bessi Valentina
Published: February 2023

Recent studies have speculated a link between Creutzfeldt-Jakob disease (CJD) and COVID-19, following the description of CJD cases after COVID-19 infection. We report the case of a 71-year-old female patient who developed neuropsychiatric and neurological symptoms after COVID-19 infection and was later diagnosed with CJD. Cerebrospinal fluid (CSF) total tau levels were slightly increased. She resulted prion protein gene (PRNP) M129V heterozygous. We aim to emphasize the role of the polymorphism at codon 129 of PRNP gene on the clinical phenotype and duration of CJD, and the CSF total tau levels that likely correlate with the rate of disease progression.
