Cel pracyCelem badania było prześledzenie zmian w zaangażowaniu polskich graczy hazardowych w hazard internetowy i pozainternetowy, w powiązaniu z czasowym ograniczeniem dostępności hazardu stacjonarnego na skutek pierwszego lockdownu.MetodaMetodą kwestionariusza internetowego zebrano wyniki od 585 graczy. Warunkiem włączenia do próby było uprawianie hazardu stacjonarnego przed 15.03.2020. Badanych zapytano o uprawianie hazardu w Internecie i poza nim w okresie przed pierwszym lockdownem (przed 03.2020), w trakcie lockdownu (15.03. – 10.05.2020) oraz sześciu miesięcy po zakończeniu lockdownu. W analizach uwzględniono także nasilenie zaburzenia hazardowego (mierzone za pomocą kwestionariusza PGSI) oraz powody ograniczenia lub nasilenia zachowań hazardowych.WynikiDominującą tendencją wśród graczy offline było utrzymanie aktywności hazardowej na tym samym poziomie lub jej ograniczenie w okresie lockdownu (blisko 95% graczy). Ograniczenie gry wyjaśniano: ograniczeniami finansowymi oraz ograniczonym dostępem do gier poza Internetem. Nasilenie gry offline tłumaczono: wolnym czasem, potrzebą odreagowania stresu i potrzebą gotówki. Spośród 394 osób uprawiających przed pandemią tylko hazard offline, 30 osób zaczęło uprawiać podczas pandemii hazard online. Inicjacja uprawiania hazardu online, jak również nasilenie hazardu online lub offline były powiązane z większym nasileniem symptomów zaburzenia hazardowego.WnioskiNasilenie zaangażowania w hazard w okresie pandemii w badanej grupie było zjawiskiem marginalnym i powiązanym z problemowym wzorcem jego uprawiania.
Exploring and explaining variation in phrase-final f0 movements in spontaneous Papuan Malay
Authors: Kaland Constantijn , Grice Martine 
Published: March 2024

Abstract
This study investigates the variation in phrase-final f0 movements found in dyadic unscripted conversations in Papuan Malay, an Eastern Indonesian language. This is done by a novel combination of exploratory and confirmatory classification techniques. In particular, this study investigates the linguistic factors that potentially drive f0 contour variation in phrase-final words produced in a naturalistic interactive dialogue task. To this end, a cluster analysis, manual labelling and random forest analysis are carried out to reveal the main sources of contour variation. These are: taking conversational interaction into account; turn transition, topic continuation, information structure (givenness and contrast), and context-independent properties of words such as word class, syllable structure, voicing and intrinsic f0. Results indicate that contour variation in Papuan Malay, in particular f0 direction and target level, is best explained by turn transitions between speakers, corroborating similar findings for related languages. The applied methods provide opportunities to further lower the threshold of incorporating intonation and prosody in the early stages of language documentation.
The role of place and manner of articulation in Kurtöp tonogenesis: refining the model
Authors: Hyslop Gwendolyn , Plane Sarah 
Published: March 2024

AbstractWhile the general acoustic mechanisms that explain the development of tone in language have been understood since at least Maspero (1912. Étude Sur La Phonétique Historique de La Langue Annamite: Les Initiales.Bulletin de l’École Française d’Extrême-Orient12. 1–126), we are still far from having a predictive theory of tonogenesis. Kurtöp, a Tibeto-Burman language of Bhutan shown to be undergoing tonogenesis, provides a rare opportunity to advance our understanding of how and why languages develop lexical tone. This study examines the role that sonority and place of articulation have in the spread of tone from voicing contrasts on preceding consonants in Kurtöp. First, we find that tone is more likely to be produced following fricatives than when following stops. Second, we see that within the stops, tone phonologises more readily following some places of articulation over others. Taken as a whole, this shows us that tone is moving through Kurtöp, following the most sonorous segments first and moving to the least sonorous segments. These findings thus help us refine our theory of tonogenesis and show that functional pressures have strong influences in this particular pathway of sound change.

Aim. To evaluate long-term oncological outcomes of pancreatoduodenectomy in resectable pancreatic head cancer in patients over 70 years of age. Materials and methods. A retrospective analysis of the Moscow Clinical Scientific Center registry revealed 63 patients aged > 70 years with resectable pancreatic head cancer. In 2016–2023, these patients underwent pancreatoduodenectomy. Males accounted for 35 %, and the median age comprised 75 years. Stage II was diagnosed in 44.4 % of patients, stage I – in 31.7 %, and stage III – in 23.8 %. Median follow-up accounted for 34.5 months. The authors analyzed the effect of patient characteristics, tumor, perioperative data and method of surgery on overall survival. Results. Adjuvant chemotherapy (p = 0.005; HR 0.28, CI 0.115–0.62) and low preoperative albumin levels (p = 0.004; HR 0.203, CI 0.28–0.61) had a significant impact on overall survival. After open surgery, 56 % of patients did not receive adjuvant chemotherapy, after minimally invasive surgery – 15.4 % (p = 0.0001). Conclusion. Minimally invasive pancreatoduodenectomy reveals no negative effect on the oncological outcomes of treatment for resectable pancreatic head cancer in patients ≥ 70 years old. Adjuvant chemotherapy and hypoalbuminemia prior to surgery are considered to be statistically significant factors influencing overall survival. Minimally invasive techniques enable adjuvant chemotherapy to be administered to a larger number of patients compared to open intervention.

Published: March 2024

Aim. To analyze the current methods of life quality assessment in patients undergoing surgical treatment for pancreatic and periampullary cancer, to study the influence of surgical treatment and postoperative complications on the quality of life. Materials and methods. The study involves a systematic review of the literature available in MEDLINE, Embase and e-Library electronic databases for 2015–2022. The methodology of the systematic review is reflected in the study protocol, designed according to PRISMA guidelines. Results. The systematic review embraces 26 studies including 4937 patients met the inclusion criteria. The present study examines design and objectives, survey forms, methods of surgical interventions and drug treatment, survey frequency and data collection methodology, risk of systematic error, etc. Conclusion. When choosing a survey form, most authors favored EORTC QLQ-C30 and EORTC QLQ-PAN26. Even the most complex surgeries such as pancreaticoduodenal resection and pancreatectomy can provide a satisfactory quality of life. Many current studies appear methodologically-challenged thereby increasing the risk of systematic error and reducing the reliability of the data. The quality of life of patients in this category is to be further investigated, the optimal principles and methodology of such studies are to be standardized, in particular, in Russian healthcare system.

Published: March 2024

Aim. To introduce the developed endoscopic classification of major duodenal papilla adenomas. Materials and methods. In 2000–2023 period, 149 patients with neoplasms of the major duodenal papilla underwent comprehensive examinations and surgical interventions. 134 cases involved endoscopic removal of papilla tumors. Results. Radical removal of the major papilla adenoma was performed in 90.5 % of cases. 16.6 % of cases revealed complications as follows: postmanipulation pancreatitis in 10 (7.9 %) cases, bleeding in 7 (5.5 %), and duodenal perforation in 4 (3.1 %). 1–3 year follow-up period revealed residual adenomatous overgrowths in 9.5 % of cases. An endoscopic classification of major papilla adenomas was developed, thereby leading to a decrease in thecomplication and re-intervention rates. The classification enables the character of intraductal spread of adenomas to be specified and indications for their endoscopic excision to be determined. Conclusion. The developed endoscopic classification of major duodenal papilla adenomas contributes to selection of the most effective and safe method of surgical intervention. An application of the classification implies unification of an endoscopic description of the tumor and consistency in patient monitoring by different specialists.

Aim. To evaluate the informativeness of endoscopic ultrasound examination in children with suspected choledocholithiasis. Materials and methods. The study enrolled 20 patients with suspected choledocholithiasis. All patients underwent endoscopic ultrasound. Patient follow-up ranged from 4 to 14 months. Results. Endoscopic ultrasound proved to be informative in all patients and determined the treatment tactics in 10 patients. In 1 observation, the results of endoscopic ultrasound allowed for omitting endoscopic retrograde cholangiopancreatography as well as surgery. No complications were reported during the diagnostic examination. Conclusion. Endoscopic ultrasound is considered to be an informative and safe method in adults as well as in children. High efficiency in detecting gallstones enabled unnecessary and traumatic surgical interventions to be avoided. Assessment of anatomic features of the ductal system during endoscopic ultrasound serves as a significant factor for safer transpapillary surgeries.

Published: March 2024

Aim. To summarize data, define indications and estimate outcomes of cholangioscopy performed by various accesses to the bile ducts. Materials and methods. In the period of 2017–2024, 68 cholangioscopies were performed in 24 (35.3 %) men and 44 (64.7 %) women. The age of patients ranged from 18 to 85 years (mean age comprises 61 years). 10 (14.7 %) cholangioscopies were performed by retrograde access, 42 (61.8 %) by antegrade access, and 16 (23.5 %) were performed intraoperatively. Results. The total amount of interventions include 21 (30.9 %) lithoextractions, 16 (23.5 %) targeted biopsies, 12 (17.6 %) recanalizations of anastomosis strictures, and 1 (1.79 %) case involved a retrieval of the “lost” bile duct stent. In 7 (10.3 %) cases cholangioscopy failed due to a small diameter of the bile ducts. Conclusion. Contemporary minimally invasive endoscopic methods considerably enlarge the possibilities for treatment of complex lesions of the bile ducts. Antegrade cholangioscopy contributes to a wider application of modern technologies for direct examination of the bile ducts and to expansion of the range of therapeutic manipulations. The introduction of antegrade cholangioscopy avoids extensive traumatic reconstructive interventions with their potential risk of complications.

Aim. To evaluate technical features, safety and efficiency of radiofrequency ablation in tumor strictures of extrahepatic bile ducts. Materials and methods. An ongoing prospective observational study from September 2022 to June 2023 enrolled patients with unresectable extrahepatic bile duct tumors. Examination involved esophagogastroduodenoscopy, endoscopic ultrasound, retrograde cholangiopancreatography and video choledochoscopy with biopsy. Ductalradiofrequency ablation with polymeric or self-expanding metallic stent placement was applied as the main treatment method for the first time in Russia. Results. 3 patients (75 %) were diagnosed with cholangiocarcinoma of stage IIb–IIIa, 1 patient – with mucinous cystic tumor with signs of severe intraepithelial neoplasia. Radiofrequency ablation was successfully performed in all patients: tumor stenosis was completely eliminated, no complications reported in the immediate and distant period. The median follow-up period amounted to 8 months. Conclusion. The results of the first application of ductal radiofrequency ablation in unresectable tumors of extrahepatic bile ducts with stenosis prove to be positive. The method is considered to be effective, minimally invasive and safe.

Aim. To develop the concept of prevention and treatment of severe complications after radical surgery for portal cholangiocarcinoma based on a comparative analysis of two periods of the surgical treatment program. Materials and methods. The study involved an analysis of multidisciplinary treatment of patients with portal cholangiocarcinoma for 8 years (2013–2020). The study consisted of two stages: program formation in 2013–2018 and evaluation of results in 2019–2020. Results. 140 patients with portal cholangiocarcinoma underwent radical or relatively radical surgery: 94 patients in the first period and 46 patients in the second period. 35 pairs of observations were formed by means of propensity score matching. In the second period, the incidence of Clavien-Dindo grade IV and V complications, CCI>40 index, duration of stay in the intensive care unit, and 90-day mortality significantly decreased. Proven reasons for the improvements included more thorough preparation of patients for the resection stage of treatment, elimination of clinical and laboratory manifestations of biliary drainage complications, careful invasive monitoring of fluid accumulations, and prevention of cholangitis. Conclusion. Maximum compensation of inflammatory and trophic disorders, elimination of jaundice, prevention and early elimination of complications as a result of their prognosis and monitoring at all stages of treatment reliably improve the immediate results of radical surgery for portal cholangiocarcinoma.
Mothering an Australian dynasty: brood provisioning in Haploscapanes barbarossa (Fabricius, 1775) (Coleoptera: Scarabaeidae: Dynastinae: Dynastini)
Authors:   Queensland Museum, Monteith Geoff , Allsopp Peter 
Published: March 2024

Females of the Australian dynastine beetle Haploscapanes barbarossa (Fabricius, 1775) excavate burrows and provision them with food for young larvae. Larvae consume that food, but not enough is provided for the larva to complete development. In northern Queensland, some of the partially developed larvae move to adjacent burrows of the cockroach Macropanesthia rhinoceros Saussure, 1895, where they feed on the considerable organic material, including leaf material and cockroach frass, that builds up in these chambers up to 1 m below the surface. In other areas of northern Australia, there are no burrowing cockroaches, so the larvae must find other food sources after the early stages.

Published: March 2024

Background: Toxocara canis is one of the most important causes of animal toxocariasis with global distribution. We aimed to find out the seroprevalence of toxocariasis in dogs in a rural area in Fars Province, south of Iran.
Methods: Dogs blood samples were collected from 60 dogs in three rural areas in the Sar Mashhad region, Fars Province. Dog sera were evaluated for anti-Toxocara antibodies by an indirect ELISA method. The association between the seropositivity and age, gender, and the sampling location were statistically evaluated.
Results: Serological assay detected anti-Toxocara antibodies in sera of 32 out of 60 dogs, corresponding to a seroprevalence of 53.3%. The rate of seropositivity was higher in the male dogs. The rate of seropositivity was higher in old dogs. This rate increased with increasing age, however, the association between age and Toxocara seropositivity was not statistically significant.
Conclusion: The high prevalence of Toxocara infection in dogs in the current study area confirms that infected dogs are an important source of Toxocara infection for their owners and people who are in close contact with these animals, especially children.

Enhanced Quantum Key Distribution and Error Minimization for 6G Networks through Optimized Multi-Head Self-Attention and Gated-Dilated Convolutional Neural Networks
Authors: Dhandapani Ilakkiaselvan , Jothi Kavitha Ramaswami 
Published: March 2024

Abstract

6G frameworks will be able to utilize higher frequencies than 5G frameworks and provide altogether higher capacity and much lower latency. First, 6G network input signals stand up to channel obstacles to open security. QKD, a cryptographic technique, allows two parties to safely exchange secret keys for message encryption and decryption. Based on quantum mechanics, any threats in the system warn the authorized users. Qubits can be distributed over fibre or free space quantum channels and encoded with several degrees of freedom. In this proposed method, QKD and Error Rate Optimization using an optimized Multi-Head Self-Attention and Gated-Dilated Convolutional Neural Network (QKD-ERO-MSGCNN) are used to extend the maximum transmission distance and improve the secret key rate (SKR). The variable velocity strategy particle swarm optimization algorithm (VVSPSOA) is used on the input signals to improve the SKR and is fed to the MSGCNN to analyse the quantum bit error rate (QBER) reduction effectively. MSGCNN alone does not optimize the QBER reduction in the channel accurately; intensified sand cat swarm optimization (ISCSO) is used to analyse the QBER reduction accurately. The proposed QKD-ERO-MSGCNN is implemented, and metrics such as accuracy, precision, SKR and QBER reduction attain higher performances when compared with existing techniques.
