BackgroundAffect dynamics, or variations in emotional experiences over time, are linked to psychological health and well-being, with moderate emotional variations indicating good psychophysical health. Given the impact of emotional state on cardiac variability, our objective was to develop a quantitative method to measure affect dynamics for better understanding emotion temporal management in Anorexia Nervosa (AN).MethodsThe study proposed an experimental and methodological approach to evaluate physiological affect dynamics in clinical settings. It tested affective transitions and temporal changes using emotional images from the International Affective Picture System (IAPS), examining physiological characteristics of a patient with AN. The methodology involved calculating a heart rate variability index, e.g., RMSSD, and using it in a Discrete Time and Discrete Space Markov chain to define, quantify, and predict emotional fluctuations over time.ResultsThe patient with Anorexia Nervosa showed a high likelihood of transitioning from positive to negative emotional states, particularly at lower arousal levels. The steady state matrix indicated a tendency to remain in highly activated pleasant states, reflecting difficulties in maintaining emotional balance.ConclusionsEmploying Markov chains provided a quantitative and insightful approach for examining affect dynamics in a patient with AN. This methodology accurately measures emotional transitions and provides a clear and interpretable framework for clinicians and patients. By leveraging Markovian indexes, mental health professionals may gain a comprehensive understanding of emotional fluctuations’ patterns. Moreover, graphical representations of emotional transitions may enhance the clinician-patient dialogue, facilitating a clearer emotional and physiological profile for the implementation of personalized treatment procedures.

Authors: Church Deirdre , Naugler Christopher , Guo Maggie , Somayaji Ranjani 
Published: February 2025

IntroductionBacterial vaginosis (BV), vulvovaginal candidiasis (VVC), and Trichomonas vaginalis (TV) commonly cause infectious vaginitis in women, especially those of reproductive age. Characterization of the epidemiology of infectious vaginitis in a contemporary population-based cohort was done to determine the longitudinal age-standardized and sex-based testing, positivity, and incidence rates and ratios of infectious vaginitis in a large Canadian healthcare region.MethodsWe conducted a population-based cohort study from March 2015 through March 2018 using the Alberta Precision Laboratories (APL) microbiology database. Calgary 2016 census data was used to calculate incidence rates (IR) and ratios (IRR) for cases and testing rates.ResultsFor testing and positivity, female sex, and younger age groups were associated with increased risk of BV, VVC, and TV infections. The annual mean population in 2016 was 1,411,660 individuals (50.3% female). A total of 40,259 cases/293,853 tests (13.7%) of BV, 32,894 cases/293,853 tests (11.2%) of VVC, and 2018 cases/342,986 tests (0.7%) of TV were identified. The overall IR for BV ranged from 0 to 609 cases per 10,000 person-years. The overall IR for VVC ranged from 0 to 445 per 10,000 person-years. The overall IR for TV ranged from 0 to 27 per 10,000 person-years. The highest age-specific testing positivity rate and IR rate for BV and VVC occurred in women aged 20–34 years and 20–34 years. For TV, female IR for BV, VVC, and TV remained stable during the study.DiscussionThese unique regional data provide insight for the development of appropriate age-specific clinical testing criteria according to relative risk of acquisition of each vaginitis agent.
A mixed method study of menstrual health in Spain: pain, disorders, and the journey for health
Authors: Sánchez-López Sara , Barrington Dani Jennifer , Poveda-Bautista Rocio , Moll-López Santiago 
Published: February 2025

IntroductionMenstrual-related symptoms and disorders, particularly dysmenorrhea, significantly impact women's well-being. Dysmenorrhea, marked by painful menstrual cramps, affects up to 95% of women, leading to debilitating symptoms that interfere with daily activities and potentially signal underlying gynecological issues. Despite its prevalence, many women experience inadequate medical support and dismissive healthcare responses.MethodsThis study employed a mixed-method approach, combining quantitative and qualitative survey data to explore Spanish women's experiences with menstrual discomforts and healthcare access. A total of 3,490 participants responded to the survey, which assessed the prevalence of menstrual discomforts, frequency of medical consultations, and perceived quality of gynecological care.ResultsFindings indicate that 70.9% of participants experience menstrual discomforts monthly or most months; despite this, a significant number of women infrequently seek gynecological care, often due to perceived dismissiveness and inadequate medical support. The qualitative analysis reflects shared experiences of pain normalization, misattribution to other conditions, and dissatisfaction with the standard treatment of contraceptive pills without thorough diagnostics. Additionally, the study reveals that in Spain, access to healthcare support for menstrual issues is highly influenced by whether the provider is public or private, demonstrating the impact of socio-economic factors and underscoring a core contributor to health inequity.DiscussionThis study highlights the persistent gender pain gap and the need for a more holistic and empathetic approach in medical practices. The authors' recommendations include incorporating gender training for healthcare professionals and promoting awareness campaigns to encourage medical consultations for menstrual pain. This research aims to improve support systems and healthcare practices, enhancing the quality of life for women in Spain.

BackgroundEthiopia faces inadequate minimum dietary diversity (MDD), which significantly contributes to rising death rates and the spread of diseases among children aged 6–23 months. The evidence of socioeconomic and regional inequalities is central to the Sustainable Development Goals (SDGs), and it is especially crucial for guiding the development of local, regional, and national policies and initiatives that address these inequalities in MDD consumption. This will help achieve the SDG target of ending all forms of malnutrition. However, there is limited evidence on socioeconomic and regional inequalities in MDD consumption among children in Ethiopia. Therefore, this study aimed to investigate the socioeconomic and regional inequalities in MDD among children aged 6–23 months in Ethiopia.MethodsThis study utilized nationally representative weighted data comprising 3,145 samples from the 2019 Ethiopia Demographic and Health Survey (EDHS). The concentration index (CIX)was employed to estimate the socioeconomic and regional inequalities in MDD consumption.ResultsThe prevalence of adequate MDD in Ethiopia was 7.11%. The concentration index (CIX) values for MDD by wealth status and region were 0.3 and 0.084, respectively, with a p-value of &lt;0.05 for both. The concentration curve was below the equality line, and adequate MDD was concentrated among the wealthy, developed, and urban regions of Ethiopia. Maternal education (0.88%), the sex of the household head (0.3%), and region (3.1%) contributed to the observed inequalities in MDD across both the poor and wealthy regions. Wealth status (11.06%), maternal age (6.7%), maternal educational status (1.87%), and residence (0.02%) contributed to the observed inequalities in MDD consumption across both the less developed and developed regions of Ethiopia.ConclusionThis study revealed that the wealth and regional inequalities observed in MDD consumption in Ethiopia were influenced by factors such as parental marital status, women’s educational status, place of residence, and short preceding birth intervals. Adequate MDD consumption among the children in Ethiopia was concentrated in the wealthy and developed regions. Therefore, efforts should focus on reducing poverty, improving maternal education, and implementing targeted interventions. In particular, nutrition and public health organizations should support less developed regions to achieve greater dietary diversity for infants and young children.

Leptin is an adipokine known as a regulator of feeding and metabolism in mammals. Previous studies on fish have revealed its role in food intake regulation in limited teleosts. However, its specific function in Siberian sturgeon, an ancient Chondrostei fish, remains poorly understood. This study represents the first successful cloning of sequences for leptin and leptin receptors in Siberian sturgeon, achieved using RT-PCR. The predicted leptin sequence in this species consists of 168 amino acids that exhibit low identity with other fish species, except within the Acipenseriformes order. Tissue distribution analysis revealed a high expression of Siberian sturgeon leptin mRNA in the liver and lepr mRNA in the hypothalamus. Fasting differentially affected the expression of leptin and lepr mRNA, with decreased levels in the hypothalamus and increased levels in the liver (leptin: 3–15 days; lepr: 6–15 days). Recombinant Siberian sturgeon leptin (Ssleptin) was produced via E. coli expression, and intraperitoneal injection (100 ng/g BW) significantly inhibited food intake. The anorectic effect was correlated with changes in hypothalamic gene expression, including downregulation of orexigenic factors (agrp, orexin, npy, and ghrelin) and upregulation of anorexigenic factors (pomc, mch, and insulin). Meanwhile, the peripheral administration of Ssleptin promoted the expression of resistin in the liver and concurrently increased cck and pyy mRNA levels in the valvular intestine. Furthermore, Ssleptin injection stimulated the expression of hypothalamic lepr, jak2, akt, and ampkα2 mRNA. These findings suggest that leptin plays a significant role in the feeding control of Siberian sturgeon and provide new insights into the evolutionary function of leptin in fish.

This paper establishes an existence and uniqueness theorem for the nonlocal sixth-order nonlinear beam differential equations with four parameters of the form u(6)+A(x)u(4)+B(x)u″+C(x)u=λf(x,u,u″,u(4)),0<x<1, subject to the integral boundary conditions: u(0)=u(1)=∫01p(x)u(x)dx, u″(0)=u″(1)=∫01q(x)u″(x)dx and u(4)(0)=u(4)(1)=∫01s(x)u(4)(x)dx such that 1−∫01p2(x)dx=α>0,1−∫01q2(x)dx=β>0,1−∫01s2(x)dx=γ>0, under some growth condition on f, and provided that an upper bound exists for the flexural rigidity λ to guarantee that no large deflections will occur.
La « villa maritime » des Lecques à Saint-Cyr-sur-Mer (Var). Documents inédits et essai de synthèse
Authors: Lavagne Henri , Varoqueaux Claude 
Published: February 2025

The roman villa at Saint-Cyr-les-Lecques (département of the Var, on the south east French Riviera) has been partiallly studied from the XVIIth century, by famous archaeologists such as abbot Barthélemy and Adrien Blanchet. The article is an essay for a synthesis using these preliminary reports but also a long unpublished account written by the architect M. R. Penchaud at the beginning of the 19th century. Eventually, Mrs. Cl. Varoqueaux, archaeo-logist of the CNRS, who made excavations on the site more recently, has also given a new contribution to confirm the chronology of the different phases of the construction. Paintings and mosaics of italic style are also more extensively described. Sculptures also authorized the hypothesis that the owner was a member of the equestrian order.

Published: February 2025

Introdução: A fraqueza adquirida na unidade de terapia intensiva (FAUTI) é uma condição frequente em pacientes de unidade de terapia intensiva resultante de fatores como a imobilização, ventilação mecânica, uso prolongado de sedação e hiperglicemia, nesses pacientes, o acompanhamento da perda de massa muscular é imprescindível, pois está intimamente ligada com o aumento da mortalidade, tempo de internação e dependência prolongada da ventilação mecânica, no entando essa monitorização é desafiadora devido às restrições impostas pelo ambiente. Nesse cenário, a ultrassonografia vem ganhando destaque como uma ferramenta promissora à beira leito para avaliação da massa muscular. Objetivos: Analisar a eficácia do ultrassom como ferramenta para avaliação da perda da massa muscular em indivíduos críticos, a fim de prever a FAUTI em pacientes não cooperativos à beira leito. Metodologia: Revisão integrativa nas bases de dados LILACS, MEDLINE, PubMed e Google acadêmico, foi realizada de setembro a novembro de 2024, priorizando os artigos em inglês e português nos últimos 6 anos. Resultados e Discussões: O tempo entre as avaliações por ultrassom nos estudos variou entre o primeiro dia de admissão e vinte e um dias, sendo identificado que há uma alteração na arquitetura muscular nos primeiros sete dias e que a massa muscular, principalmente do quadríceps femoral foi perdida, juntamente com a diminuição do ângulo de penação com aumento progressivo na pontuação da ecogenicidade. Considerações finais: Pacientes críticos frequentemente apresentam perda significativa de massa muscular, especialmente no início da internação, sendo mais evidente no grupo muscular quadríceps femoral, o que apresenta um risco clínico aumentado para o desenvolvimento de FAUTI e a ultrassonografia mostrou-se uma ferramenta eficaz para identificar alterações da arquitetura do muscular.

Published: February 2025

Introdução: A apendicite aguda é a inflamação do apêndice vermiforme, decorrente da obstrução de sua luz, com maior prevalência em homens, ao final da infância, 2° e 3° décadas. Corresponde a principal indicação cirúrgica não eletiva. Clinicamente, se manifesta como uma dor abdominal em região periumbilical, com posterior migração para fossa ilíaca direita. Pode ser acompanhada de náuseas, vômitos, anorexia e febre. O diagnóstico é clínico, podendo ser complementado por exames de imagem. A apendicectomia é a intervenção de escolha para o tratamento definitivo e pode ser realizada por via aberta ou laparoscópica. Atualmente, há debates sobre qual técnica cirúrgica seria mais adequada, considerando os resultados e possíveis complicações pós-operatórias associadas a cada uma das abordagens. Objetivo: Apresentar conhecimentos acerca da apendicectomia e suas duas vias de acesso cirúrgico (aberta e laparoscópica), considerando os resultados e complicações decorrentes de cada uma delas. Métodos: Foi realizada uma busca nas bases de dados PubMed, Scielo e Lilacs, com a utilização dos descritores: “Open Appendectomy”, “Laparoscopic Appendectomy”, “Open Appendectomy” AND “Complications” e “Laparoscopic Appendectomy” AND “Complications”. Foram selecionados XX artigos, de 2019 a 2024, com critérios de inclusão e exclusão previamente definidos. Discussão: A apendicectomia laparoscópica vem crescendo ao longo dos anos, sendo muito prevalente em países de alta renda e menos prevalente nos de baixa renda. No Brasil, somente 6,3% das apendicectomias foram por essa via. A cirurgia via laparoscopia é considerada menos invasiva, segura, com menor tempo de recuperação e internação hospitalar, menos complicações pós-operatórias e óbitos, quando comparada a via convencional. Entretanto, ainda está associada a gastos elevados para sua ampla utilização. Conclusão: A apendicectomia via laparoscópica está associada a um tempo de internação mais curto, menor taxa de mortalidade e redução das complicações pós-operatórias. No entanto, apresenta custo elevado, devido a necessidade de equipamentos e treinamento da equipe.

Artykuł ukazuje kulturę studencką w Krakowie w drugiej połowie XIX w. jako zjawisko uwarunkowane politycznie i społecznie. Autorka przedstawia działalność przedstawicieli pokolenia zaliczanego przez badaczy do grona przedburzowców galicyjskich – formacji intelektualnej, która jeszcze przed powstaniem styczniowym, w schyłkowej fazie romantyzmu zapowiadała pojawienie się na ziemiach polskich tendencji pozytywistycznych. W drugiej połowie XIX w. młodzież akademicka podejmuje próby samoorganizowania się. Powołuje do istnienia organizacje, stowarzyszenia i koła (formalne i nieformalne) o charakterze samopomocowym, które zakładają wzajemną troskę członków o swój rozwój intelektualny i naukowy, udział w życiu kulturalno-społecznym miasta i pomoc socjalną dla najuboższych. W okresie przed powstaniem styczniowym w kręgach studenckich nasilają się nastroje patriotyczne. Młodzież krakowska bierze udział w demonstracjach patriotycznych i konspiracji, a także bezpośrednio w walce. Jedną z takich grup zorientowanych samokształceniowo jest „pracownia Filippiego”, działająca w Krakowie u początku lat 60. XIX w., której członkami byli m.in. Michał Bałucki, Adam Bełcikowski, Józef Szujski, Jan Matejko i Tadeusz Wojciechowski.

Authors: Bukowski Przemysław , Tarchała Andrzej 
Published: February 2025

W czasie pandemii COVID-19 i związanych z nią ograniczeń studenci stanęli przed wyzwaniami dotyczącymi spotkań studenckich, obejmującymi komunikację, integrację oraz organizację życia akademickiego. Również obecnie studenci zmagają się z wyzwaniami dotyczącymi rzeczywistości hybrydalnej, która łączy przestrzeń tradycyjną i wirtualną życia człowieka. Wyzwania te wpływają na spotkania studenckie, zarówno formalne, jak i nieformalne, odbywające się w ramach uczelni i poza nią. Badanie preferencji studentów dotyczących spotkań w rzeczywistościach tradycyjnej i wirtualnej jest istotne, ponieważ po`zwala wykazać, które formy spotkań w przekonaniu studentów wzmacniają, a które osłabiają relacje interpersonalne, wpływają na rozwój osobisty i ogólną atmosferę panującą na uczelni.
Artykuł prezentuje wyniki badań dotyczących opinii studentów na temat spotkań studenckich w kontekście rzeczywistości hybrydalnej. Zaprezentowano wyniki ankiety przeprowadzonej wśród studentów Uniwersytetu Ignatianum w Krakowie (UIK) i Uniwersytetu Papieskiego Jana Pawła II w Krakowie (UPJP2). Celem badania była charakterystyka oddziaływania rzeczywistości hybrydalnej na spotkania studenckie z perspektywy studentów oraz określenie wyzwań, z którymi mierzą się w tej rzeczywistości. Wyniki badania mogą mieć istotne implikacje dla praktyki edukacyjnej i organizacyjnej na uczelniach wyższych, przyczyniając się do lepszego rozumienia potrzeb i oczekiwań studentów. Autorzy traktują przeprowadzone analizy jako badanie pilotażowe, które zamierzają rozwinąć w kolejnym tekście.

Niniejszy artykuł omawia historię i zasób nieistniejącej rzymskokatolickiej biblioteki parafialnej w Bełzie, która uległa zniszczeniu wraz z kościołem i przylegającą plebanią-klasztorem w 1944 r. wskutek podpalenia obiektów przez ukraińskich nacjonalistów. Na podstawie zachowanych we Lwowie dwóch inwentarzy parafialnych z 1869 i 1872 r. zdołano odtworzyć spis cennego księgozbioru, w którym znajdowały się liczne starodruki, rękopisy liturgiczne i metrykalne oraz książki z I połowy XIX w. Daty graniczne całości zawierały się w latach 1545–1853. Niniejsza publikacja jest pierwszym opracowaniem historii i zasobu tej biblioteki.
Preliminary study on the speed-of-sound measurement of cartilage tissue based on a two-layer model
Authors: NITTA Naotaka , Washio Toshikatsu , Hikishima Keigo 
Published: February 2025

Abstract
Knee osteoarthritis is a serious disease in an aging society, and early diagnosis is crucial because no fundamental treatment currently exists. Cartilage is often modeled as a poroelastic body with a deformable solid matrix saturated with fluid or water, and its water retention capacity is evaluated by the change in fluid content in the poroelastic body over time. In this study, we focus on the speed of sound as an indicator of fluid content. Considering the actual structure including soft and cartilage tissues, we propose a method for measuring the speed of sound in cartilage tissue using the cartilage surface and subchondral bone surface as reflectors. The effectiveness of the proposed method was demonstrated by performing simulations and phantom experiments, and the measured values of the speed of sound coincided well with the true values in both the simulations and phantom experiments.
Machine learning molecular dynamics study of thermal boundary resistance between barrierless interconnect metals and SiO2 interlayer dielectric
Authors: Hashimoto Shuichiro , Nishimura Yusuke , Watanabe Takanobu 
Published: February 2025

Abstract
Employing machine learning molecular dynamics (MD) calculation, we evaluated thermal boundary resistance (TBR) between barrierless interconnect unitary metals and SiO2 interlayer dielectric (SiO2-ILD). Our non-equilibrium MD calculation with machine learning interatomic potential revealed that the TBR of W/SiO2 interface is lower than that of Ru/SiO2 and Mo/SiO2 interface. Greater overlap of phonon density of states (DOS) in the W/SiO2 interface than that of the Ru/SiO2 and the Mo/SiO2 interface, resulting in the lower TBR. SiO2-induced lattice strain and disorder in W contribute to the greater overlap of the phonon DOS in the W/SiO2 interface. Furthermore, greater adhesion energy which is influenced by interfacial bond strength at the W/SiO2 interface, also contributes to the lower TBR. These findings highlight the importance of interfacial properties on phonon thermal transport through barrierless interconnect metal/ILD interfaces in deeply-scaled logic nodes.
