Published: January 2024

AbstractReciprocity is one of the most prominent explanations for the evolution of stable cooperation. Although reciprocity has been studied for decades in numerous animal species and behavioural contexts, its underlying proximate mechanisms remain unclear. Domestic dogs provide a useful model species for the study of proximate mechanisms, though there are currently inconsistent findings regarding dogs' propensity to reciprocate. Here, we investigated whether, after minimal training, pet dogs would press a button, which remotely controlled a food dispenser, to deliver food to an enclosure occupied by a helpful conspecific that had provided them with food or an unhelpful conspecific that had not provided them with food. We included an asocial control condition in which the enclosure was unoccupied and a social facilitation control in which the food delivery mechanism was non‐functional. Whether subjects were familiar with the helpful and unhelpful conspecifics was also varied. In addition, to investigate potential mechanisms underlying reciprocity, we measured subjects salivary oxytocin concentration before and after they experienced the helpful and unhelpful acts. There was no effect of the previous helpfulness or the familiarity of the partner on the number of times subjects pressed the button. However, there was also no effect of the presence of a partner or the operationality of the food delivery mechanism on the number of button presses, indicating that subjects were not pressing the button to provision the partner. Moreover, the experience of the helpful or unhelpful act did not influence subjects' salivary oxytocin concentration. Variation in findings of reciprocity across studies appears to correspond with differing training protocols. Subjects' understanding of the task in the current study may have been constrained by the limited training received. Additional tests to verify subjects' understanding of such tasks are warranted in future studies.
Sarcasm‐based tweet‐level stress detection
Authors: Prashanth KVTKN , Ramakrishnudu Tene 
Published: January 2024

AbstractPsychological stress has evolved as an important health concern across the globe. The vulnerability to stress and the ramifications of it have only worsened during the time of the COVID‐19 pandemic. This necessitates a timely diagnosis of stress before the condition progresses to chronicity. In this context, the popularity of social media like Twitter, where large numbers of users share opinions without any social stigma, has emerged as a major resource of human opinions. This has led to an increased research interest in social media‐based stress detection techniques. However, tweet‐level stress detection techniques in the literature have left a void in leveraging the text information in tweets, especially the presence of sarcastic expressions in the tweet's text content. To this end, a novel method called “Sarcasm‐based Tweet‐Level Stress Detection” (STSD) is proposed in this work with the modification of the logistic loss function to detect tweet‐level stress by availing the information of sarcasm that exists in the tweet‐content. The principle of the STSD model is to minimize the loss for non‐sarcastic tweets while maximising the loss for sarcastic tweets. Furthermore, extensive preprocessing and dimensionality reduction are performed using kernel principal component analysis (kernel PCA) to improve the performance by reducing the dimensions. The experimental results show that the proposed STSD model, when applied along with kernel PCA, records a significant improvement in accuracy by a minimum of 5.25% and a maximum of 9.19% over baseline models. Also, there is an increment in F1‐score by at least 0.085 points and a maximum of 0.164 points when compared to the baseline models.

Published: January 2024

AbstractAimTo evaluate the association between apical periodontitis (AP) and atherosclerotic cardiovascular disease (ASCDV).MethodologyA total of 65 periodontally and systemically healthy patients (age ≥ 40 years) were included in the study. Periapical status was assessed through dental examination and periapical radiographs; 33 subjects had AP (AP+), while 32 acted as control (AP−). Moreover, data regarding their periapical index (PAI) score and the Decayed, Missing, and Filled Teeth (DMFT) index were recorded. All subjects underwent echo‐colour Doppler assessment of carotid intima‐media thickness (CIMT), carotid plaques, degree of stenosis using the North American Symptomatic Carotid Surgery Trial (NASCET) method, maximum diameter of the abdominal aorta (maximum AA) and common iliac arteries (CIA) diameters. Furthermore, peripheral blood flow was also measured using the ankle‐brachial index (ABI). Simple and multiple regression analyses were performed.ResultsAmong AP+ patients, 57.58% disclosed at least one sign of subclinical carotid atherosclerosis. Multiple regression analysis identified AP as a significant risk indicator for carotid plaques [OR = 4.87 (1.27, 18.98; p = .021)] and marked carotid intima‐media thickenings (OR = 14.58 [1.22, 176.15], p = .035). A significant association was established between AP and other cardiovascular (CV) variables (CIMT, NASCET, and maximum AA). On the contrary, a higher PAI score does not correlate to increased odds of carotid alterations, and the presence of AP did not prove any significant change in CIA and ABI. No significant correlation was established between DMFT and other variables.ConclusionsResults from the current study highlight that the presence of AP may be regarded as a risk indicator for ASCVD, with AP being associated with 5‐fold increased odds of having carotid plaques and 15‐fold increased odds of having marked carotid intima‐media thickenings. Further studies should be conducted in order to verify whether AP treatment could be beneficial for ASCVD signs.

Published: January 2024

AbstractMXenes, a large family of two‐dimensional carbides and/or nitrides, are among the most studied materials worldwide due to their great diversity of structures and compositions. Their unique properties find use in several applications. Typically, they are manufactured by selective wet‐chemical etching of layered MAX phase ceramics, which are produced nowadays primarily for MXene synthesis. However, the synthesis of MAX phases has not been changed since the time of their use in structural and high‐temperature applications, and it has not been optimized for MXene manufacturing. The main purpose of this study is to develop a porous Ti3AlC2 MAX phase that can be easily ground into individual grains without time‐consuming, harsh, and tedious crushing and milling steps. Moreover, we also demonstrate the synthesis of highly porous Ti3AlC2 from an inexpensive titanium sponge instead of a highly pure titanium powder and explain the mechanisms of reaction sintering and formation of porous MAX phase. MXene obtained from this MAX phase, Ti3C2Tx, shows larger flake size and higher electrical conductivity in thin films, compared to the materials produced from the costly fine titanium powder. The proposed approach may apply to the synthesis of other MAX phases as well.

ObjectivesMany congenital hydronephroses spontaneously resolve. This study evaluated a long‐term follow‐up of more than 4 years of patients with congenital hydronephrosis at a single center.MethodsIn total, 215 patients (286 kidneys) with congenital hydronephrosis were included. Hydronephrosis outcomes (resolution, improvement, and persistence) and time‐to‐outcome were evaluated.ResultsFourteen patients underwent early surgical intervention until the age of 2 years. A total of 189 congenital hydronephrosis cases (66%) showed resolution at a median of 16 months (interquartile range: 7–21 months) and 169 (80%) of 210 kidneys with grade I to II hydronephrosis showed resolution at a median of 14 months (interquartile range: 6–23 months). Of 76 kidneys with grade III to IV hydronephrosis, 24 (32%) showed resolution at a median of 29 months (interquartile range: 24–41 months), and 56 (74%) showed improvement to grade II or less at a median of 12 months (interquartile range: 5–23 months). Of the 76 kidneys with grade III to IV hydronephrosis, five required delayed pyeloplasty at a median of 66 months (interquartile range: 42–89 months). One patient was asymptomatic, with a marked worsening of hydronephrosis and decreased renal function 6 years after the resolution of hydronephrosis.ConclusionsNone of the patients with grade I to II hydronephrosis required surgical treatment, and a shorter follow‐up may be sufficient. Grade III to IV severe hydronephrosis should be considered for a longer and more careful follow‐up, given the possibility of asymptomatic exacerbation of hydronephrosis.

AbstractBackgroundVestibular migraine (VM) is a common cause of recurrent vertigo. Migraine headache preventative therapies are currently prescribed to control vertigo symptoms in VM. Clinical trials of nutraceuticals for migraine headache prevention have shown positive outcomes, but, to date, there have been no studies to assess their effectiveness in the management of VM.AimsTo report the effects of nonprescription therapy management on VM symptoms.MethodsWe undertook a prospective, questionnaire‐based assessment of patients diagnosed with VM between November 2019 and August 2021 at two Sydney tertiary referral clinics. Patients were advised on optimising sleep, hydration, exercise and nutrition and instructed to use an over‐the‐counter combination product containing riboflavin 200 mg, magnesium 150 mg, coenzyme Q10 75 mg and feverfew 200 mcg. Symptom severity and frequency were assessed using the Dizziness Handicap Inventory (DHI), the Vertigo Symptom Score short‐form (VSS‐sf) and two visual analogue scales for severity (VAS‐s) and frequency (VAS‐f) before and 3 months after commencing treatment.ResultIn 82 participants (78% female; mean age, 44 ± 14 years) we recorded a decrease in DHI (mean, 16.8 [95% confidence interval (CI), 12.8–20.9], VSS‐sf (9.3, 7.1–11.5), VAS‐s (3.0, 2.2–3.8) and VAS‐f (2.8, 2.1–3.4), equating to an improvement of 44.1%, 44.9%, 44.1% and 38.9% for each measure respectively. On the DHI and VSS‐sf, 41 (50%) and 44 (53.7%) patients showed improvement in their symptoms; 39 (47.6%) and 36 (43.9%) patients noted no change and two patients reported worsening. The supplement was well‐tolerated.ConclusionsThe results provide preliminary evidence that VM symptom frequency and severity can be reduced by using nonprescription therapies.

AbstractAimTo examine the impact of both individual and cumulative social determinants of health (SDoH) on the likelihood of developing periodontitis, while also exploring any gender disparities in this relationship.Materials and MethodsData of self‐reported SDoH domains and sub‐items based on Healthy People 2030 were obtained from the U.S. National Health and Nutrition Examination Surveys between 1999 and 2014. Logistic regression models, weighted by survey responses, were used to examine the relationship between SDoH (including eight sub‐items and the cumulative number of unfavourable SDoH) and periodontitis. The results were further analysed by gender.ResultsA total of 18,075 participants (8867 males and 9208 females) were included in the main analysis, of which 5814 (32.2%) had periodontitis. The study found that certain unfavourable SDoH were individually associated with higher odds of periodontitis, and the cumulative number of unfavourable SDoH was positively linked to the odds of developing periodontitis. Furthermore, males exposed to more unfavourable SDoH appeared to be more susceptible to developing periodontitis than females.ConclusionsThe findings suggest that unfavourable SDoH, especially when they accumulate, are associated with an increased odds of periodontitis and contribute to gender disparities within the U.S. population.

Published: January 2024

AbstractForked carrots are often used as animal feed or discarded directly, which affects ​the economic returns of growers and leads to resource waste and environmental pollution. After trimming, forked carrots become easier to peel and can be further processed. However, the lack of relevant studies and equipment hinders the full use of forked carrots, and the identification of fork points and determination of the trimming path are the main challenges in trimming forked carrots with unique and diverse shapes. Therefore, an automatic carrot‐trimming path recognition solution based on contour analysis and machine learning was proposed in this study to address the above challenges. Specifically, a cascaded model and a parallel model consisting of Multilayer Perceptron (MLP) and Support Vector Machine (SVM) were constructed to identify fork points, and three trimming path determination methods based on fork points and carrot contours were proposed. The results demonstrated cascaded and parallel models achieved 100% and 92.7% recall rates, respectively, with accuracy rates of 90.4% and 100% and repetition rates of 97.1% and 96.4%. Among the trimming path determination methods, both the dynamic convex hull method and the static convex hull method achieved a convexity of 94.7%, surpassing 93.1% for the slope method. The static convex hull method exhibited the fastest speed in determining the trimming path, taking only 0.0032 s per carat. The parallel model and the static convex hull method could be effectively used for online determination of the trimming path for forked carrots.Practical applicationsTrimming forked carrots enhances usability, reduces resource wastage, and mitigates environmental pollution. Leveraging contour‐based machine learning algorithms, we achieved precise fork point recognition with broad applicability. Using fork point and carrot contour data, we determined trimming paths that render carrots convex for mechanical peeling. This approach contributes to advancing sustainable agriculture by optimizing resource utilization.

AbstractBackground and AimThe incidence of colorectal cancer (CRC) in individuals under 50 is increasing worldwide. We conducted an analysis of colonoscopy findings in high‐risk individuals under 50 in the CRC screening program in Tianjin, China, to determine the detection rate and risk factors of advanced adenomas (AA), advanced colorectal neoplasia (ACN), colorectal neoplasia (CN).MethodsOur study investigated individuals aged 40–49 who underwent CRC screening and completed colonoscopy, 2012–2020, while the 50–54 age group served as a control. We compared the detection rates of AA, ACN, and CN among three age groups using univariate and multivariable logistic regression analyses, and investigated the risk factors associated with AA, ACN, and CN among individuals aged 40–49.ResultsWe found a gradual increase in the detection rate of AA, ACN, and CN among individuals aged 40–54. The detection rates for AA (OR 0.58; 95% CI 0.41–0.81), ACN (OR 0.58; 95% CI 0.43–0.77), and CN (OR 0.64; 95% CI 0.56–0.74) were lower in individuals aged 40–44 compared to 45–49. The detection rates of AA (OR 1.08; 95% CI 0.87–1.34) and ACN (OR 1.12; 95% CI 0.93–1.35) in individuals aged 45–49 were comparable with 50–54. Besides, lifestyle factors, BMI, and FIT are not associated with the detection rates of AA, ACN, and CN among individuals aged 40–49.ConclusionsOur study reveals screening data in individuals under 50, indicating comparable detection rates of AA and ACN in individuals aged 45–49 and 50–54. These findings provide valuable data support for optimizing the optimal age to initiate screening.

AbstractAimTo evaluate the predictive validity and reliability of the Waterlow scale in critically adult hospitalised patients.DesignA multi‐centre cohort study.MethodsThis study was conducted in 72 intensive care units (ICUs) in 38 tertiary hospitals in Gansu Province, China. All adults admitted to the ICU for greater than or equal to 24 h without pressure injury (PI) on admission were screened by the Waterlow scale on admission, during ICU stay and ICU discharge from April 2021 to February 2023. Receiver operating characteristic (ROC) curves were used to determine a potential cut‐off value for critical adult hospitalised patients. Cut‐off values were then determined using Youden's index, and sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated based on these cut‐off values. Test–retest reliability was used to evaluate inter‐rater reliability.ResultsA total of 5874 critical patients on admission were included, and 5125 of them were assessed regularly. The area under curve (AUC) was 0.623 (95% CI, 0.574–0.690), with a cut‐off score of 19 showing the best balance among sensitivity of 62.7%, specificity of 57.4%, positive predictive value of 2.07% and negative predictive value of 99.08%. The test–retest reliability between the first assessment and the regular assessment was 0.447.ConclusionsThe Waterlow scale shows insufficient predictive validity and reliability in discriminating critical adults at risk of PI development. To further modify the items of the Waterlow scale, exploring specific risk factors for PI in the ICU and clarifying their impact degree was necessary. Risk predictive models or better tools are inevitable in the future.Patient or Public ContributionPatients or family members supported nurses with PI risk assessment, skin examination and other activities during the inquiry.

AbstractBackgroundWe aimed to examine the effects of endometriosis on the rate of abnormal placentation by comparing the data of pregnant women with and without endometriosis.MethodsA case–control study was conducted to compare the perinatal outcomes between women with and without endometriosis. In the subgroup analysis, magnetic resonance imaging (MRI) scans of pregnant women with placenta previa were used to measure the cervical angle and its relationship with endometriosis. The cervical angle was measured as the angle between the cervical glands and the line perpendicular to the spinal column in each sagittal MRI section.ResultsWe retrospectively analyzed data from 3453 cases of singleton deliveries between 2015 and 2019 at two study facilities. Among them, 159 had clinically or surgically confirmed endometriosis. The odds ratio (OR) for abnormal placental position was significantly higher in pregnant women with endometriosis (OR. 2.82; 95% confidence interval [CI], 1.58–5.04). The OR was 3.21 (95% CI, 1.57–6.55) in the endometriosis‐surgery group (91 patients) and 2.32 (95% CI, 0.91–5.88) in the non‐surgery group (68 patients). Furthermore, 44 women who underwent pelvic MRI after 30 weeks of gestation were included to examine the cervical angle. Then, we compared the date of pregnant women with (n = 6) and without endometriosis (n = 38). Regardless of placental attachment position, the cervical angle was significantly lower in the group with than in the group without a history of endometriosis.ConclusionPregnant women with a history of endometriosis may have stronger uterine retroversion, which could potentially contribute to abnormal placental positioning.
