Authors: Nybacka Sanna , Kinnander Anton , Augustin Hanna , Bärebring Linnea 
Published: October 2024

Abstract
Background
Irritable bowel syndrome (IBS) is a common gastrointestinal disorder in which the intake of food is known to exacerbate symptoms. Experiencing food related symptoms can lead to avoidance of food, and cause anxiety related to food intake. We aimed to explore perceptions of the healthiness of food, food avoidance, and food-related worry and anxiety among individuals with and without IBS.

Methods
This study was based on a survey conducted in January-February 2017. In total, 2000 participants aged 20–65 were invited by postal letter randomly obtained through the Swedish state personal address register. The questionnaire included aspects of socioeconomic position, different disorders including IBS and food intolerances, food avoidance, and food-related worry or anxiety.

Results
In total, 538 participants were included in this study, of whom 8.4% (n = 45) reported having IBS. There were few differences regarding the perceived healthiness of foods between individuals with and without IBS. Participants with IBS avoided gluten (OR 3.45, p = 0.002), lactose (OR 5.0, p < 0.001) and alcohol (OR 2.0, p = 0.042) more frequently than individuals without IBS, and avoidance was driven by abdominal pain. Participants with IBS also reported feeling more worried and having anxiety about diet than those without IBS (p = 0.032 and p = 0.002, respectively).

Conclusion
This study indicates that individuals with IBS perceive most foods as equally healthy as individuals without IBS. Having IBS increases the odds of avoiding gluten, lactose, and alcohol. Worry and anxiety related to diet were more common among individuals with IBS, and these aspects need to be considered both in clinical practice and in future research.

Abstract
Background
Application of data-driven strategies may support veterinarians’ decision-making, benefitting pig disease prevention and control. However, little is known about veterinarians’ need for data utilisation to support their decision-making process. The current study used qualitative methods, specifically focus group discussions, to explore veterinarians’ views on data utilisation and their need for data tools in relation to pig health and welfare management in Spain, the Netherlands, and Ireland.

Results
Generally, veterinarians pointed out the potential benefits of using technology for pig health and welfare management, but data is not yet structurally available to support their decision-making. Veterinarians pointed out the challenge of collecting, recording, and accessing data in a consistent and timely manner. Besides, the reliability, standardisation, and the context of data were identified as important factors affecting the efficiency and effectiveness of data utilisation by veterinarians. A user-friendly, adaptable, and integrated data tool was regarded as potentially helpful for veterinarians’ daily work and supporting their decision-making. Specifically, veterinarians, particularly independent veterinary practitioners, noted a need for easy access to pig information. Veterinarians such as those working for integrated companies, corporate veterinarians, and independent veterinary practitioners expressed their need for data tools that provide useful information to monitor pig health and welfare in real-time, to visualise the prevalence of endemic disease based on a shared report between farmers, veterinarians, and other professional parties, to support decision-making, and to receive early warnings for disease prevention and control.

Conclusions
It is concluded that the management of pig health and welfare may benefit from data utilisation if the quality of data can be assured, the data tools can meet veterinarians’ needs for decision-making, and the collaboration of sharing data and using data between farmers, veterinarians, and other professional parties can be enhanced. Nevertheless, several notable technical and institutional barriers still exist, which need to be overcome.

Abstract
Purpose
Vision-threatening diabetic retinopathy (VTDR) included severe non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR) and clinically significant diabetic macular edema (DME). To compare the axial length (AL) and assess its influence on VTDR across different ages.

Methods
A retrospective cohort study. Medical chart review was performed in 736 consecutive patients with VTDR. The patients were divided into young (≤ 45 years) and elderly group (> 45 years) based on their age at the diagnosis of VTDR. After at least one year of standardized treatments, all eligible patients were followed up. The main outcome measures included the presence of tractional retinal detachment (TRD) involving foveal, final best-corrected visual acuity (BCVA), the development of neovascular glaucoma (NVG), and recurrent vitreous hemorrhage (VH) post-vitrectomy. ALs were compared between two age groups. The impact of AL on clinical outcomes was determined by logistic analyses after controlling for systemic parameters.

Results
The study included 144 patients ≤ 45 years and 592 patients > 45 years. Young patients had significantly longer AL than elderly participants (23.9 mm vs 23.0 mm, p < 0.001). Over a median follow-up of 25.9 months, a larger proportion of young patients developed TRD (34.7% vs 16.2%, p < 0.001) and recurrent VH (18.6% vs 10.3%, p = 0.040) than elderly patients. In elderly group, longer AL is an independent protective factor in preventing TRD (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.4–0.7; P < 0.001). However, this beneficial effect was not observed in young patients.

Conclusions
Young patients with VTDR exhibited significantly longer AL but more aggressive clinical signs with compromised prognosis. In elderly group, a longer AL independently reduced the risk of TRD, while this protective effect did not exist for young patients.

Published: October 2024

Abstract
Background
To examine whether weekday-to-weekend sleep duration (WWD) difference and specific WWD patterns are associated with mental and somatic health and academic performance in a student population.

Methods
This study utilized cross-sectional data from the SHoT-2018 survey which includes responses from 50,054 full-time university/college students in Norway. Participants completed online questionnaires and reported sleep duration separately for weekdays and weekends. Medium sleep duration was defined as 7 to 9 h, short sleep duration as < 7 h and long sleep duration as > 9 h. Regression analyses were used to examine whether the degree and patterns of WWD was associated with health-related outcomes and academic performance.

Results
The mean age of the sample was 23.2 years and comprised of 68.8% women. Most students (81.7%) slept longer on weekends compared to weekdays and 30.0% of the students reported a mean sleep duration shorter than 7 h. WWD difference was positively associated with higher odds of overweight/obesity, dissatisfaction with life, psychological distress, somatic burden and failed study exam. Concerning WWD patterns, the odds of students reporting unfavorably on the outcomes were particularly high for those who slept short on both weekdays and weekends, while those who slept short on weekdays seemed to benefit from sleeping longer (“catching up”) on weekends.

Conclusions
Overall, WWD was associated with adverse health outcomes for students. Short sleep duration both on weekday and weekend was associated with the most detrimental outcomes in terms of health and academic performance, while sleeping in on weekends may alleviate some of the detriments.

Published: October 2024

Abstract
Background
Psychological repercussions resulting from coronavirus disease 2019 (COVID-19) have been encountered, such as anxiety, depression, insomnia, and post-traumatic stress disorder (PTSD). The study aimed to assess the frequency and severity of PTSD, depression, and anxiety in a sample of Egyptian patients with COVID-19 infection and analyze potential risk factors. The current study is a descriptive cross-sectional, hospital-based study, conducted from August 2020 to June 2021. The sample was selected from patients diagnosed with COVID-19 infection at Ain Shams University hospitals (outpatient clinics and inpatient units). Patients underwent a COVID severity criteria scoring system, structured clinical interview for DSM-IV (SCID-I), PTSD checklist–Civilian Version (PCLC), Beck depression inventory, and Taylor’s manifest anxiety scale.

Results
PTSD was observed in 79.29% of the study sample, 61.43% had depression, and 18.57% had anxiety. The severity of COVID-19 infection was significantly associated with PTSD severity mean scores (P value = 0.027). Furthermore, a significant relationship was observed between the severity of depression and COVID-19 infection severity (P value = 0.028). The number of comorbid medical risk factors demonstrated significance to PTSD severity (P value = 0.014).

Conclusion
A significant portion of the study’s patients experienced psychiatric consequences following COVID-19 infection, with 79.29% developing PTSD, 61.43% suffering from depression, and 18.57% experiencing anxiety. Various factors, such as the presence of chronic medical illnesses and the number of co-morbid medical risk factors, were observed to contribute to these psychiatric outcomes. Therefore, comprehensive psychiatric assessment and management in COVID-19 patients especially with severe forms of the disease and hospitalized patients are mandatory.
Cystic cardiac myxoma: a rare variant of cardiac myxoma in a woman with acute stroke
Authors: Singh Damandeep , Jagia Priya , Mukherjee Aprateem , Zameer Alaina , Arava Sudheer Kumar 
Published: October 2024

Abstract
Background
Cardiac myxomas are the most common primary benign tumors of the heart usually presenting as an oval mass attached to the interatrial septum. Mild heterogenous enhancement is typically seen upon contrast administration. Myxomas are benign, however can present with embolic episodes necessitating prompt diagnosis and treatment.

Case presentation
A middle-aged woman presenting with acute ischemic stroke was detected to have a complex cystic mass in the left atrium on echocardiography. Further evaluation with cardiac magnetic resonance imaging narrowed a differential diagnosis to hemangioma, hemangioendothelioma, sarcoma, hydatid cysts, bronchogenic cysts, and cystic variant of cardiac myxoma. CTA demonstrated arterial supply from the left circumflex artery supplying the lesion. Following surgical excision, histopathology analysis suggested a cystic cardiac myxoma with secondary degeneration.

Conclusion
Cystic masses in the heart are challenging to diagnose due to similar imaging characteristics, and misdiagnosis may lead to further major downstream complications such as stroke, hemorrhage, and hemodynamic alterations causing syncope. Therefore, surgical excision of a cystic cardiac mass is justified to establish a definitive histopathological diagnosis and prevent further downstream complications. We hereby report a rare case of cystic cardiac myxoma in the left atrium showing intense progressive enhancement in CMR and CTA in a middle-aged woman presenting with acute stroke. This case highlights an exceedingly rare variant of cystic cardiac myxoma.

Abstract
Background
The deformation of oral and maxillofacial region leads to not only the damage of morphology and function, but also a series of aesthetic and psychological problems, severely affecting the quality of life of patients. Oral tissue engineering refers to developing biomaterials for repair or regeneration, with the application of tissue engineering technologies. This has become an area of increasing prominence. Current biologically inert materials are insufficient to fulfill clinical requirements. Therefore, tissue-engineered biomaterials with bioactive, even bionic properties are desperately needed.

Main body
The complexity of the anatomy and the diversity of tissue types of oral and maxillofacial region pose great challenges to the regeneration, in the aspects of both biomaterials and manufacturing technologies. Biomaterials in clinical practice or research have evolved from natural materials to synthetic materials, from homogeneous materials to multiple composite materials. And now composite materials have increasingly demonstrated their advantages in terms of physicochemical and biological properties over conventional materials. In terms of manufacturing, traditional coating, sintering, and milling technologies can no longer satisfy the requirements for high-precision bionic structures of oral-tissue-engineering biomaterials. Scientists have turned to biofabrication technologies such as microfluidics and additive manufacturing.

Short conclusion
This review aims to summarize the noteworthy advancements made in biomaterials of oral tissue engineering. We outlined the current biomaterials and manufacturing technologies and focused on various applications of these materials that may be connected to clinical treatment and research. We also suggested the future direction of development for biomaterials in oral tissue engineering. In future, biomaterials characterized by precision, functionalization, and individualization will be manufactured through digital, microfluidic, and 3D printing technologies.

Published: October 2024

AbstractUlcerative colitis (UC) is a chronic inflammatory bowel disease characterized by abdominal pain, diarrhea, rectal bleeding, and weight loss. The pathogenesis and treatment of UC remain key areas of research interest. Various factors, including genetic predisposition, immune dysregulation, and alterations in the gut microbiota, are believed to contribute to the pathogenesis of UC. Current treatments for UC include 5-aminosalicylic acids, corticosteroids, immunosuppressants, and biologics. However, study reported that the one-year clinical remission rate is only around 40%. It is necessary to prompt the exploration of new treatment modalities. Biologic therapies, such as anti-TNF-α monoclonal antibody and JAK inhibitor, primarily consist of small molecules targeting specific pathways, effectively inducing and maintaining remission. Given the significant role of the gut microbiota, research into intestinal microecologics, such as probiotics and prebiotics, and fecal microbiota transplantation (FMT) shows promising potential in UC treatment. Additionally, medicinal herbs, such as chili pepper and turmeric, used in complementary therapy have shown promising results in UC management. This article reviews recent findings on the mechanisms of UC, including genetic susceptibility, immune cell dynamics and cytokine regulation, and gut microbiota alterations. It also discusses current applications of biologic therapy, herbal therapy, microecologics, and FMT, along with their prospects and challenges.

Abstract

Context
Androgen excess (AE)-related symptoms can vary widely and may appear across the life course.

Objective
We assessed the prevalence of signs of potential AE and heterogeneity by demographic/health characteristics.

Methods
We used data of 24 435 participants who consented and enrolled during November 2019 to December 2022 in a US digital cohort to evaluate the prevalence and heterogeneity of self-reported signs of potential AE: possible hirsutism (having thick coarse hair on ≥4 of 8 body locations), hair level on the chin, hair loss on top of the head, and moderate to severe acne.

Results
The prevalence of possible hirsutism, having several/a lot of hair on the chin, significantly reduced hair/visible scalp on top of the head, and moderate to severe acne were 6.9%, 12.6%, 1.7%, and 31.8%, respectively. While possible hirsutism and moderate to severe acne decreased with age (range: 18-86 years), hair on the chin and hair loss on the head increased with age. Participants who self-identified as Hispanic or South Asian reported a higher prevalence of possible hirsutism (11.2%, 16.9%, vs 6.3% among non-Hispanic White participants). Participants with higher body mass index had a higher prevalence of possible hirsutism. Moderate to severe acne was more common among those with polycystic ovary syndrome. Possible hirsutism and hair loss were less common among participants using hormones for contraception.

Conclusion
In this large cohort, signs of potential AE varied by demographic and health factors. These results could provide a new understanding of how potential AE may appear differently in diverse groups, informing future work to develop more inclusive evaluation at a population level.
Older spiny mice (Acomys cahirinus) have delayed and spatially heterogenous ear wound regeneration
Authors: Varholick Justin A. , Thermolice Jazmine , Godinez Gizelle , Dos Santos Vanessa , Kondapaneni Rishi , Maden Malcolm 
Published: October 2024

ABSTRACT
The African spiny mouse (Acomys cahirinus) is a unique mammalian model of tissue regeneration, regenerating 4 mm ear-hole punches with cartilage, adipocytes, hair follicles, and muscle. However, the time to regenerate ear tissue varies from 20 to 90 days and muscle regeneration is inconsistent. Some report that older spiny mice have delayed regeneration without investigation on the regenerative capacity of muscle. We thought that delayed regeneration and inconsistent muscle regeneration could be linked via age-related nerve degeneration. While the current study found that spiny mice aged 6–9 months had delayed regeneration compared to 3–4 month-old spiny mice, the capacity of muscle regeneration was unrelated to age, and there was little evidence for age-related nerve degeneration. Instead, the regeneration of muscle, cartilage and adipocytes was spatially heterogeneous, declining in amount from the proximal to distal region of the regenerated tissue. Also, cartilage regeneration in the distal region was decreased in ≥22-month-old Acomys and adipocyte regeneration was decreased in those older than 6 months, compared to 3–4 month olds. While the underlying mechanisms for delayed and spatially heterogenous regeneration remain unclear, age and the spatial region of the regenerated tissue should be considered in experimental designs with spiny mice.

Background: Adult-onset Still’s disease (AOSD) is a rare systemic inflammatory disease characterized by fever, rash, arthritis, and multi-organ involvement. Macrophage activation syndrome (MAS), a serious complication of AOSD, poses significant diagnostic and therapeutic challenges. Case Presentation: A 32-year-old male was diagnosed with AOSD in 2020 after being hospitalized for a fever of unknown origin and elevated liver enzymes. The patient was initially treated with corticosteroids and methotrexate but subsequently discontinued both treatment and follow-up. In September 2023, he presented with fever, sore throat, and elevated inflammatory markers. After screening for infections, methylprednisolone (MP) treatment was initiated because of AOSD activation. The following day, the patient was admitted to the intensive care unit due to an altered state of consciousness. Brain magnetic resonance imaging revealed brainstem involvement. Empirical treatments were initiated, including intravenous MP, and immunoglobulin therapy. Due to suspected macrophage activation syndrome (MAS), anakinra (ANA) infusion was initiated. Significant improvement was observed after the ANA infusion. Conclusion: This case highlights the complex management of severe AOSD complications, emphasizing the role of early recognition, aggressive therapy, and multidisciplinary care in improving outcomes.
