Determinants of age at first sex inequality between women and men youth in Uganda: A decomposition analysis
Authors: Luwedde Mary , Sserwanja Quraish , Katantazi Nehemiah
Published: September 2022

Introduction

Teenage pregnancies and sexually transmitted diseases are major public health problems in Uganda. Early sexual debut is one of the main routes of these public health problems. This study aimed to identify factors that explain age at first sex inequality between men and women Ugandan youth.

Methods

This study used secondary data from a cross-sectional Uganda demographic health survey (2016). Participants were 10 189 sexually experienced youth. Using Stata 14, intermediary analysis was done to assess the statistical association between explanatory variables and age at first sex in a multiple logistic regression analysis. Oaxaca decomposition was used to decompose factors that explain inequalities in age at first sex between men and women youth.

Results

Intermediary results showed Islam, many household members, residing in the eastern region, and being divorced/widowed were predictors of early age at first sex. While secondary education, higher education, blue-collar jobs, and being 20 to 30 years old were protective factors against early age at first sex. Material, behavior/cultural, psychosocial, and demographic explanatory factors jointly explained a statistically significant portion of the observed gap in early age at first sex between women and men youth. More women were at a disadvantage at an early age at first sex compared to men youth. About 96.37% of this gap was explained by unequal distribution of material, behavior/cultural, psychosocial, and demographic factors between men and women youth. Relationship to household head (49%), education (16.87%), occupation (8,94%), number of household members (8.57%), using the internet (7.99%), and reading newspapers or magazines (4.39%) made a significant contribution to the explanation of early age at first sex inequality between men and women youth.

Conclusions

Results showed early age at first sex inequality between women and men youth that favored men. Programs designed to address early age at first sex and related health outcomes must combat inequities in education, employment opportunities, access to sexual reproductive information through internet, and newspapers or magazines between men and women youth. They should also foster household relationships and monitor girls.
The role of voltage-gated sodium channel genotypes in pyrethroid resistance in Aedes aegypti in Taiwan
Authors: Chung Han-Hsuan , Tsai Cheng-Hui , Teng Hwa-Jen , Tsai Kun-Hsien
Published: September 2022

Background

Aedes aegypti is the major vector of dengue that threatens public health in tropical and subtropical regions. Pyrethroid-based control strategies effectively control this vector, but the repeated usage of the same insecticides leads to resistance and hampers control efforts. Therefore, efficient and prompt monitoring of insecticide resistance in local mosquito populations is critical for dengue control.

Methodology/Principal finding

We collected Ae. aegypti in southern Taiwan in March and October 2016. We analyzed the voltage-gated sodium channel (vgsc) genotypes of parentals (G0) and G1 adults after cypermethrin insecticide bioassay. Our results showed that four VGSC mutations (S989P, V1016G, F1534C, and D1763Y) associated with resistance were commonly detected in field-collected Ae. aegypti. The frequencies of these four mutations in the local mosquito population were significantly higher in October (0.29, 0.4, 0.27 and 0.11) than in March (0.09, 0.16, 0.18 and 0.03). Specific vgsc combined genotypes composed of the one to four such mutations (SGFY/SGFY, SVCD/SVCD, SGFY/PGFD, SVCD/SGFY, PGFD/PGFD, and SVCD/PGFD) shifted towards higher frequencies in October, implying their resistance role. In addition, the cypermethrin exposure bioassay data supported the field observations. Moreover, our study observed an association between the resistance level and the proportion of resistance genotypes in the population.

Conclusions/Significance

This is the first study to demonstrate the role of four-locus vgsc genotypes in resistance evaluation in a local Ae. aegypti population in Taiwan. This alternative method using resistance-associated genotypes as an indicator of practically insecticide resistance monitoring is a useful tool for providing precise and real-time information for decision makers.
On the effectiveness of graph matching attacks against privacy-preserving record linkage
Authors: Heng Youzhe , Armknecht Frederik , Chen Yanling , Schnell Rainer
Published: September 2022

Linking several databases containing information on the same person is an essential step of many data workflows. Due to the potential sensitivity of the data, the identity of the persons should be kept private. Privacy-Preserving Record-Linkage (PPRL) techniques have been developed to link persons despite errors in the identifiers used to link the databases without violating their privacy. The basic approach is to use encoded quasi-identifiers instead of plain quasi-identifiers for making the linkage decision. Ideally, the encoded quasi-identifiers should prevent re-identification but still allow for a good linkage quality. While several PPRL techniques have been proposed so far, Bloom filter-based PPRL schemes (BF-PPRL) are among the most popular due to their scalability. However, a recently proposed attack on BF-PPRL based on graph similarities seems to allow individuals’ re-identification from encoded quasi-identifiers. Therefore, the graph matching attack is widely considered a serious threat to many PPRL-approaches and leads to the situation that BF-PPRL schemes are rejected as being insecure. In this work, we argue that this view is not fully justified. We show by experiments that the success of graph matching attacks requires a high overlap between encoded and plain records used for the attack. As soon as this condition is not fulfilled, the success rate sharply decreases and renders the attacks hardly effective. This necessary condition does severely limit the applicability of these attacks in practice and also allows for simple but effective countermeasures.
Pan-cancer gene expression analysis of tissue microarray using EdgeSeq oncology biomarker panel and a cross-comparison with HER2 and HER3 immunohistochemical analysis

Published: September 2022

Molecular and protein biomarker profiling are key to oncology drug development. Antibody-drug conjugates (ADCs) directly deliver chemotherapeutic agents into tumor cells based on unique cancer cell biomarkers. A pan-cancer tissue microarray (TMA) data set and gene panel were validated and gene signature analyses were conducted on normal and cancer tissues to refine selection of ADC targets. Correlation of mRNA and protein levels, and human epidermal growth factor receptor (HER) expression patterns were assessed. An EdgeSeq biomarker panel (2862 genes) was used across 8531 samples (23 solid cancer types/subtypes; 16 normal tissues) with an established TMA data set, and immune cell and cell cycle gene signatures were analyzed. Discriminating gene expression signatures were defined based on pathological classification of cancer subtypes. Correlative analyses of HER2 and HER3 mRNA (EdgeSeq) and protein expression (immunohistochemistry[IHC]) were performed and compared with publicly available data (The Cancer Genome Atlas[TCGA]; Cancer Cell Line Encyclopedia[CCLE]). Gene expression patterns among cancer types in the TMA (EdgeSeq) and TCGA (RNA-seq) were similar. EdgeSeq gene signature analyses aligned with the majority of pathological cancer types/subtypes and identified cancer-specific gene expression patterns. TMA IHC H-scores for HER3 varied across cancer types/subtypes. In a few cancer types, HER3 mRNA and protein expression did not align, including lower liver hepatocellular carcinoma IHC H-score, compared with mRNA. Although all TNBC and ovarian cancer subtypes expressed mRNA, some had lower protein expression. This was seen in TMA and TCGA data sets, but not in CCLE. The EdgeSeq TMA data set can expand upon current biomarker data by including cancers not currently in TCGA. The primary analysis of EdgeSeq and IHC comparison suggested a unique protein-level regulation of HER3 in some tumor subtypes and highlights the importance of investigating protein levels of ADC targets in both tumor and normal tissues.
Tax preference, financing constraints and enterprise investment efficiency—Experience, of China’s enterprises investment
Authors: Zhai Liangliang , Feng Yujing , Li Fumin , Zhai Liping
Published: September 2022

This paper takes the 2014 pilot project of accelerated depreciation of fixed assets as a quasi-natural experiment, and builds a Propensity Score Matching–Difference in Differences (PSM-DID) model based on the data of Chinese listed companies from 2000 to 2019 to test the impact of tax preference on enterprise investment efficiency and its mechanism. The results show that the policy inhibits supported enterprises investment efficiency significantly. Heterogeneity analysis shows that the policy causes greater investment efficiency losses for small and medium-sized enterprises, non-state-owned enterprises and asset-heavy enterprises. The mechanism test found the reason why the policy eased financing constraints but inhibited investment efficiency in short-term. After a variety of robustness tests, the above basic conclusions are still valid. Although the accelerated depreciation policy of fixed assets is conducive to expanding the scale of investment, the incentive effect on investment efficiency is not obvious, and even shows a restraining effect. Given the existence of heterogeneity, the design of the policy should not only distinguish industries, but also pay attention to the differences between different enterprises in the same industry. Strengthening research and development (R&D) innovation and improving the matching mechanism between human capital and fixed investment will help give full play to the incentive effect of this policy. The research in this paper helps to deepen the understanding of the microeconomic effects of tax policy and identify the internal mechanism, which not only enriches the relevant literature, but also provides a reference for the government to better use tax policy to promote the high-quality development of enterprises.
Cell death induced in glioblastoma cells by Plasma-Activated-Liquids (PAL) is primarily mediated by membrane lipid peroxidation and not ROS influx

Published: September 2022

Since first identified in 1879, plasma, the fourth state of matter, has been developed and utilised in many fields. Nonthermal atmospheric plasma, also known as cold plasma, can be applied to liquids, where plasma reactive species such as reactive Oxygen and Nitrogen species and their effects can be retained and mediated through plasma-activated liquids (PAL). In the medical field, PAL is considered promising for wound treatment, sterilisation and cancer therapy due to its rich and relatively long-lived reactive species components. This study sought to identify any potential antagonistic effect between antioxidative intracellularly accumulated platinum nanoparticles (PtNPs) and PAL. We found that PAL can significantly reduce the viability of glioblastoma U-251MG cells. This did not involve measurable ROS influx but instead lead to lipid damage on the plasma membrane of cells exposed to PAL. Although the intracellular antioxidative PtNPs showed no protective effect against PAL, this study contributes to further understanding of principle cell killing routes of PAL and discovery of potential PAL-related therapy and methods to inhibit side effects.
Bibliometric analysis of hotspots and frontiers in cancer-related fatigue among ovarian cancer survivors
Authors: Liu Yuanxia , Liu Qianxia , Jiang Xiaolian
Published: September 2022

Objectives

To explore and analyze research hotspots and frontiers in CRF in ovarian cancer patients to provide an evidence-based basis for scholars and policymakers.

Background

Ovarian cancer is one of the most common and lethal gynecological malignancies. Cancer-related fatigue (CRF) is an annoying and pervasive side-effect that seriously affects the activities of daily living and decreases the quality of life (QoL) of cancer survivors.

Methods

The literature was retrieved from the Web of Science Core Collection (WOSCC) from inception to 2021-12-31. CiteSpace was used to discuss research countries, institutions, authors, and keywords.

Results

This study ultimately included 755 valid publications, and the number of publications showed a gradual upward trend. The countries, institutions, authors, and journals that have published the most articles and cited the most frequently were the United States, the University of Texas MD Anderson Cancer Center, Michael Friedlander and Amit M Oza, Gynecologic Oncology, and Journal of Clinical Oncology. The top three high-frequency keywords were Ovarian cancer, chemotherapy, and clinical trial. The top three keywords with the strongest citation bursts were cyclophosphamide, double-blind, and open-label.

Conclusions

Conducting multi-center, large-sample, randomized controlled clinical trials to determine whether chemotherapeutic agents have severe adverse effects and to discuss the relationship between CRF and QoL and overall survival in cancer survivors are hotspots in this field. The new trends may be applying double-blind, randomized controlled trials to clarify the causes of CRF and open-label, randomized trials to determine the efficacy, safety, and tolerability of chemotherapeutic agents.

Anterior cruciate ligament (ACL) rupture represents one of the most recurrent knee injuries in soccer players. To allow a safe return to sport after ACL reconstruction, standardised and reliable procedures/criteria are needed. In this context, wearable sensors are gaining momentum as they allow obtaining objective information during sport-specific and in-the-field tasks. This paper aims at proposing a sensor-based protocol for the assessment of knee stability and at quantifying its reliability. Seventeen soccer players performed a single leg squat and a cross over hop test. Each participant was equipped with two magnetic-inertial measurement units located on the tibia and foot. Parameters related to the knee stability were obtained from linear acceleration and angular velocity signals. The intraclass correlation coefficient (ICC) and minimum detectable change (MDC) were calculated to evaluate each parameter reliability. The ICC ranged from 0.29 to 0.84 according to the considered parameter. Specifically, angular velocity-based parameters proved to be more reliable than acceleration-based counterparts, particularly in the cross over hop test (average ICC values of 0.46 and 0.63 for acceleration- and angular velocity-based parameters, respectively). An exception was represented, in the single leg squat, by parameters extracted from the acceleration trajectory on the tibial transverse plane (0.60≤ICC≤0.76), which can be considered as promising candidates for ACL injury risk assessment. Overall, greater ICC values were found for the dominant limb, with respect to the non-dominant one (average ICC: 0.64 and 0.53, respectively). Interestingly, this between-limb difference in variability was not always mirrored by LSI results. MDC values provide useful information in the perspective of applying the proposed protocol on athletes with ACL reconstruction. Thus, The outcome of this study sets the basis for the definition of reliable and objective criteria for return to sport clearance after ACL injury.
Understanding the long-term impact of flooding on the wellbeing of residents: A mixed methods study

As the effects of climate change become more visible, extreme weather events are becoming more common. The effects of flooding on health are understood but the long-term impact on the well-being of those affected need to be considered. This mixed methods secondary analysis of a cross-sectional survey examined the extent to which being flooded in the past is associated with ongoing concerns about flooding. Survey data were collected from residents in Hull 11 years after the initial flooding event. Respondents were asked about the floods in 2007 and their current level of concern about flooding. Ordinal logistic regression explored the effect of age and tenancy status as predictors of current concern. Textual data were analyzed using thematic content analysis. Responses were received from 457 households, of whom 202 (48%) were affected by flooding in 2007. A fifth of respondents were very concerned about future flooding. Those who were not flooded were significantly less concerned about the risk of future flooding (U = 33391.0, z = 5.89, p < 0.001). Those who reported negative health and wellbeing effects from the floods were significantly more concerned about future flooding than those whose health was not affected (U = 7830.5, z = 4.43, p < 0.001). Whilst some residents were reassured by the introduction of new flood alleviation schemes, others did not feel these were adequate, and worried about the impact of climate change. The financial and emotional impacts of the floods still resonated with families 11 years after the event, with many fearing they would not cope if it happened again. Despite the 2007 floods in Hull happening over a decade ago, many of those affected continue to experience high levels of anxiety when storms are forecast. Residents feel powerless to protect themselves, and many remain unconvinced by the presence of new flood alleviation schemes. However, with the ongoing threat of climate change, it may be that other residents are unrealistic in their expectation to be ‘protected’ from flood events. Therefore, public health agencies need to be able to mobilize organizations to come together to pro-actively support families affected by flooding, to ensure those in need do not fall through the gaps of public healthcare delivery.

Rink hockey is a highly specialized and physiological demanding sport with sparse research regarding the game and athletes’ characteristics. A cross-sectional study was developed to characterize the body composition and grip strength of elite male rink hockey players and to establish the relationship between ethnicity on body composition and grip strength. A sample of 100 elite rink-hockey athletes aged 26.59 ± 6.02 participated in the study, comprised of 69 Caucasian male adults aged 27.58 ± 6.44 years and 31 Black African male adults aged 24.39 ± 4.27. Body composition was assessed by anthropometric measurements. Static grip strength was assessed with an adjustable dynamometer. Multiple regression analysis was applied to understand which variables constraints body fat percentage (BF) and grip strength. Body mass showed an average of 76.36 ± 9.18 kg for 175.80 ± 5.87 cm of height and BF% of 10.82 ± 5.07%. Maximal right grip strength was 50.91 ± 6.26 kg and 50.27 ± 6.23 kg for left grip strength. Four predictors accounted for 70.01% of the variance of BF%: abdominal circumference (p < 0.001), right thigh circumference (p < 0.001), right calf circumference (p = 0.001) and ethnicity (p = 0.016). Three predictors accounted for 13.1% of the variance of right grip strength: ethnicity (p = 0.013), chronological age (p = 0.024) and right distal thigh circumference (p = 0.014). Results suggest that elite rink hockey athletes have a specific anthropometric identity, which at the elite level may lead to reduced body fat and greater handgrip strength. Ethnicity seems to predict body fat and grip strength in elite rink hockey athletes.
MicroRNA-206 suppresses growth and metastasis of breast cancer stem cells via blocking EVI-1-mediated CALR expression

Aim to investigate the effect of miR-206 on the growth and metastasis of breast cancer stem cells and clarify the precise mechanism of miR-206 on EVI-1-mediated CALR expression in driving malignant phenotype. Our results showed that miR-206 mimics suppressed CALR expression, inhibited the proliferation and metastasis ability of breast cancer stem cells and finally induced cellular apoptosis. Over-expression of CALR could effectively attenuate the cytotoxic effect of miR-206. Further studies demonstrated that EVI-1 could be served as a key regulator of miR206-mediated CALR expression. Elevation of EVI-1 can reverse the function of miR-206 on induction of CALR.
Political power, performance and ritual: Cultural policy as a framework for the construction of political charisma in the city of Valencia (1991–2015)
Authors: Rius-Ulldemolins Joaquim , Díaz-Solano Pau
Published: September 2022

The cultural dimension of politics is not secondary but rather a constitutive element of its social dynamics and of the logic of power, which must be visualized to be effective. Some authors, including Jeffrey Alexander and Randall Collins, have elaborated upon this dimension: the former with the concept of political performance, and the latter with rituals and social domination. The combination of the two perspectives is useful for us to look at the use of the inaugurations of momentous events and festivities with a new light – as a privileged instrument to legitimize a narrative of power and to create symbols of dominance embodied by political figures. This fabrication of narrative charisma in politics could be observed in Valencia (Spain) between 1991 and 2015, during the long political domination of conservative regionalism. Likewise, this case is a clear example of how almost absolute political dominance can fall apart, partly because of deficient performances and failed political rituals. This fact highlights the fragility, contingency of power and dependence on its symbolic performativity.
Mediating mainstream and fringe masculinities on Jordanian comedy shows: Roya TV as a case study
Authors: Al-Mahadin Salam
Published: September 2022

Jordanian cultural space has been dominated by the abstract figure of thenashmi, an Arabic word of obscure origin denoting chivalry, generosity, hospitality and courage. It has become indelibly associated with East-Banker Jordanian masculinity, specifically with national emblems including army, police, and civil defence officers, and national sports teams. Palestinian-Jordanian masculinities owe their cultural constructs to a different set of socio-economic and political contingencies that situate them in the much-poorer refugee camps of East Amman. This article aims to explore how the Jordanian channel Roya TV has afforded a platform to comedy productions that entrench the figure of the fringe masculinity of thedawanji(trouble-makers) as an antidote to the mainstream masculinity of thenashmiwho dominates state-owned television and radio stations, and virtually all cultural media of representation. Adopting an affective-discursive approach through a quantitative and qualitative analysis of the top 200 episodes of the most viewed comedy shows on Roya TV, the article will argue that the emphasis on the figure of thedawanjihas resulted in high levels of physical and verbal aggression and extremely negative portrayals of female characters on these comedy shows which are widely watched by both adults and children.
El pluralismo religioso en la teología actual
Authors: Matito Fernández José Ramón
Published: September 2022

A la luz de las nuevas maneras de desarrollar vías de comprensión e interpretación de la diversidad religiosa en la teología cristiana del siglo XXI, este trabajo se propone analizar algunos de los elementos fundamentales de lo que debe constituir una hermenéutica teológica interreligiosa, que sostenga y ayude a dar forma a las variantes actuales de la teología de las religiones. Las diferentes formas de realizar esa labor (teología de la historia de las religiones, teología del diálogo interreligioso, teología comparada, teología interreligiosa), reclaman una nueva forma de abordar la cuestión de la diversidad religiosa, caracterizada, sobre todo, por el diálogo, como punto de partida, y no simplemente como meta, y por el diseño de unos principios hermenéuticos propios que constituyan el método y el lenguaje de una auténtica teología de la alteridad y del encuentro, que proporcione una mirada enriquecida sobre la realidad de las otras religiones y sobre las formas de los propios fundamentos de la fe cristiana.
Objetividad de la revelación y subjetividad de la experiencia religiosa
Authors: Sueiro Samuel
Published: September 2022

Frente a la tendencia actual hacia una excesiva subjetivación de lo religioso, el cristianismo no desliga la dimensión subjetiva de la experiencia creyente de la revelación objetiva de Dios; al contrario, la objetividad de la revelación hace posible y forma parte de la experiencia religiosa, y permite que su apropiación subjetiva pueda ser valorada, discernida y criticada, al mismo tiempo que alimentada, propuesta y enriquecida. En lugar de concebir al sujeto como criterio absoluto de verdad, el cristianismo piensa la relación con Dios en términos de integración, encuentro y comunión, donde la alteridad, la historia y la libertad quedan aseguradas y potenciadas. Así se expresa de modo insuperable en Jesucristo y de modo alcanzable en la vida de los santos.
