ObjectivesThere is a lack of in-depth studies on men's personal experiences of having hypospadias across different aspects of their lives. We therefore aimed to explore the experience of having hypospadias in relation to identity and interpersonal relationships.Subjects and methodsUsing purposive sampling, we included 17 adult men aged 20–49 with variation in hypospadias phenotype. The informants further represented variation in sexuality, relationship status, parental status, and familial cultural context. In-depth interviews were conducted with each informant and the data was analysed using qualitative content analysis.ResultsWe identified four categories. Firstly, The internal experience of hypospadias in relation to being different, being impacted, and being masculine. The remaining three categories related to interpersonal spaces: Intimate spaces, comprising personal relationship with sex, having sex, and being in a relationship; Familial spaces, comprising being a son, and becoming a father; and Public spaces, comprising being hidden, being naked, and peeing. We identified the latent theme varying impact and coping, highlighting differences in experiences relating to both the internal and interpersonal.DiscussionIssues related to hypospadias included struggles with identity and confidence, as well as recurring patterns of social and sexual avoidance. While informants generally related to certain shared experiences, there is large variation in how much hypospadias impacts life, ranging from hardly at all to extensively. This could also fluctuate over time, with puberty and adolescence being an especially sensitive period. Functional and aesthetic outcomes are potentially important for well-being, especially in the case of more severe complications, while personal and interpersonal circumstances play a role in coping and the overall experience of the individual.ConclusionHealthcare, research, and other channels such as patient groups may be able to offer support to those who need it to help more boys and men with hypospadias live unhindered lives.

IntroductionModern cancer treatment strategies aim at achieving cancer remission by using targeted and personalized therapies, as well as harnessing the power of the immune system to recognize and eradicate the cancer cells. To overcome a relatively short-lived response due to resistance to the administered drugs, combination therapies have been pursued.ObjectiveThe objective of this study was to use high-throughput data generation technologies such as mass spectrometry and proteomics to investigate the broader implications, and to expand the outlook, of such therapeutic approaches. Specifically, we investigated the systems-level response of a breast cancer cell line model to a mixture of kinase inhibitors that has not been adopted yet as a standard therapeutic regime.MethodsTwo critical pathways that sustain the growth and survival of cancer cells, EGFR and PI3K/AKT, were inhibited in SKBR3/HER2+ breast cancer cells with Lapatinib (Tyr kinase inhibitor) and Ipatasertib (Ser/Thr kinase inhibitor), and the landscape of the affected biological processes was investigated with proteomic technologies.ResultsOver 800 proteins matched by three unique peptide sequences were affected by exposing the cells to the drugs. The work corroborated the anti-proliferative activity of Lapatinib and Ipatasertib and uncovered a range of impacted cancer-supportive hallmark processes, among which immune response, adhesion, and migration emerged as particularly relevant to the ability of drugs to effectively suppress the proliferation and dissemination of cancer cells. Changes in the expression of key cancer drivers such as oncogenes, tumor suppressors, EMT and angiogenesis regulators underscored the inhibitory effectiveness of drugs on cancer proliferation. The supplementation of Lapatinib with Ipatasertib further affected additional transcription factors and proteins involved in gene expression, trafficking, DNA repair, and development of multidrug resistance. Furthermore, over fifty of the impacted proteins represent approved or investigational targets in the DrugBank database, which through their protein-protein interaction networks can inform the selection of effective therapeutic partners.ConclusionAltogether, the exposure of SKBR3/HER2+ cells to Lapatinib and Ipatasertib kinase inhibitors uncovered a broad plethora of yet untapped opportunities that can be further explored for enhancing the anti-cancer effects of each drug as well as of many other multi-drug therapies that target the EGFR/ERBB2 and PI3K/AKT pathways.

BackgroundKawasaki disease (KD) is a self-limiting and acute systemic vasculitis of unknown etiology, mainly affecting children. Ferulic acid (FA), a natural phenolic substance, has multiple pharmacological properties, including anti-inflammatory, anti-apoptosis, and anti-fibrosis, and so on. So far, the protective effects of FA on KD have not been explored.MethodsIn this study, we established Candida albicans water soluble fraction (CAWS)-induced mouse coronary artery vasculitis of KD model and the tumor necrosis factor α (TNF-α)-induced human umbilical vein endothelial cells (HUVECs) injury model to investigate the anti-inflammatory and anti-apoptosis effects of FA on KD, and try to elucidate the underlying mechanism.ResultsOur in vivo results demonstrated that FA exerted anti-inflammatory effects on KD by inhibiting the infiltration of CD45-positive leukocytes and fibrosis around the coronary artery. Additionally, FA downregulated the levels of inflammatory and chemotactic cytokines, alleviated splenomegaly, and exhibited anti-apoptotic effects on KD by reducing TUNEL-positive cells, downregulating BAX expression, and upregulating BCL-2 expression. In addition, Our in vitro findings showed that FA could effectively inhibit TNF-α-induced HUVEC inflammation like NF-κB inhibitor QNZ by downregulating the expression of pro-inflammatory cytokines as well as attenuated TNF-α-induced HUVEC apoptosis by reducing apoptotic cell numbers and the BAX/BCL-2 ratio, which could be reversed by the AMPK inhibitor compound c (CC). The further mechanistic study demonstrated that FA could restrain vascular endothelial cell inflammation and apoptosis in KD through activating the AMPK/mTOR/NF-κB pathway. However, FA alone is hard to completely restore KD into normal condition.ConclusionIn conclusion, FA has potential protective effects on KD, suggesting its promising role as an adjuvant for KD therapy in the future.

IntroductionThe development and optimization of novel diagnostic imaging prototypes heavily rely on experimental work. In radiology, this experimental work involves the use of phantoms. When testing novel techniques to demonstrate their advantages, anthropomorphic phantoms are utilized. The aim of this study was to investigate seven materials for 3D printing to replicate the radiological properties of breast lesions.MethodsTo achieve this objective, we utilized three fused filament fabrication materials, namely, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), and polyethylene terephthalate glycol (PET-G), along with resins such as White v4 Resin, Flexible 80A v1 Resin, Model v2 Resin, and Wax40 v1 Resin, to 3D print seven irregularly shaped lesions. These lesions were used to prepare a set of seven physical phantoms, each filled with either water or liquid paraffin, and one of the printed lesions. The phantoms were then scanned using a mammography unit at 28 kVp. Additionally, six computational breast phantoms, replicating the shape of the physical phantoms, were generated. These computational models were assigned the attenuating properties of various breast tissues, including glandular tissue, adipose tissue, skin, and lesions. Mammography images were generated under the same experimental conditions as the physical scans. Both the simulated and experimental images were evaluated for their contrast-to-noise ratio (CNR) and contrast (C).DiscussionThe results indicated that the studied resins and filament-based materials are all suitable for replicating breast lesions. Among these, PLA and White v4 Resin exhibited the densest formations and can effectively approximate breast lesions that are slightly less attenuating than glandular tissue, while ABS and Flexible 80A v1 Resin were the least dense and can represent fat-containing breast lesions. The remaining materials provided good approximations for malignant lesions. These materials can be utilized for constructing phantoms for experimental work, rendering the model a valuable tool for optimizing mammography protocols, ensuring quality control of mammography X-ray equipment, and aiding in the diagnosis and assessment of breast cancer.

BackgroundThis study used a person-centered approach to identify the specific performance of decent work in various groups to determine the heterogeneity of its five dimensions.MethodThe Decent Work Scale, Work Need Satisfaction Scale, Socioeconomic Status Scale, Job Satisfaction Scale, and Life Well-being Scale were used to conduct a network survey of organizations in various industries in Mainland China. A total of 1,000 questionnaires were distributed, and 780 valid responses were obtained.ResultsThe results showed that the decent work of participants could be divided into three types: low salary, low free time, and high decent work. The results showed no significant difference in age among the groups, whereas the differences in socioeconomic status were significant. Welch’s test was used to determine differences in the positive outcomes of the three potential types of decent work, and the results showed significant differences in work need satisfaction, job satisfaction, and life well-being among all groups.ConclusionThis study examined the characteristics of decent work more realistically, showing that decent work is not an all-or-nothing structure and that its intrinsic components should be flexibly combined according to the research background and purpose.

IntroductionHomelessness is a phenomenon of social exclusion and poverty that has increased alarmingly during recent years. Homeless people (HP) experience violations of several basic human rights or needs that impact their well-being. Therefore, the aim of this research was to assess the health status and self-perceived health of HP and examining the impact of homelessness on their health.MethodsWe used an explanatory sequential mixed-methods approach that integrated a quantitative cross-sectional study within critical social and ethno-sociological qualitative frameworks. Data were collected in Palma, Spain, from December 1, 2020, to January 1, 2023. A total of 198 HP were recruited from the streets and public areas. Basic human needs (Virginia Henderson model), medical diagnoses, substance abuse (DAST-10), diet quality (IASE), depression (PHQ-9), and social support (SSQ-6) were assessed. Then, 17 semi-structured interviews were conducted and were analyzed using thematic content and discourse analysis. Quantitative and qualitative data were integrated and jointly analyzed.ResultsThe 79.3% of the participants were men, mean age of 47.8 ± 12.2 years. The 76.4% were Spanish. The participants reported severe difficulties in accessing the labor market, and that this greatly affected their self-esteem and mental health. The 48.9% of the participants suffered from one or more chronic diseases, and 50.3% were diagnosed with a mental health disorder. The participants generally did not consider health problems as a central concern. The health needs that most affected the participants were related to food, safety, and social support. HP frequently felt unsafe, fearfully, and anxious.ConclusionHomelessness, unemployment, and social exclusion have significant negative impacts on the health and wellbeing of HP. Precarious work conditions and deficiencies in the welfare system contribute significantly to homelessness. These results highlight the need for systemic solutions that extend beyond short-term housing initiatives.

BackgroundThe use of Anabolic-androgenic steroids (AAS) among gym members has become a significant concern due to their impact on physical training and performance. Research worldwide indicates a notable prevalence of AAS use among athletes and gym attendees, often involving substances that are neither safe nor legal.ObjectivesThis study aims to determine the prevalence of AAS use among gym attendees in Amman, Jordan, and to explore the knowledge, attitudes, and behaviors associated with AAS use.MethodsThe study involved 399 participants from 35 randomly selected gyms in the metropolitan area of Amman, Jordan. A cluster sampling technique was used to select a diverse and representative sample of gym attendees. Data was collected using a self-administered questionnaire that assessed AAS use, knowledge, attitudes, and behavioral factors. Statistical analyses were conducted using chi-square tests to explore the relationships between AAS use and categorical variables, while logistic regression was employed to identify predictors of AAS use.ResultsThe analysis revealed significant associations between AAS use and various factors, including knowledge, attitudes, behavioral factors, and demographic variables such as gender, age, exercise frequency, reasons for exercise, and total exercise duration. The study identified key predictors of AAS use among gym attendees in Amman, highlighting the importance of demographic and behavioral factors.ConclusionThe findings underscore the need for targeted interventions to address misconceptions and promote safer practices among gym-goers in Amman. The study provides critical insights that can guide the development of strategies, policy adjustments, and educational initiatives aimed at reducing AAS misuse and fostering a healthier gym culture in the region.

Published: August 2024

ObjectivesIn the province of Quebec, Canada, interdisciplinary support groups (ISGs) are mandated to support those who are involved in the clinical, administrative, legal and ethical aspects of medical assistance in dying (MAiD). This article presents the results of a mixed-method, multi-phase study carried out in 2021 on ISGs with the aim to describe current ISG practices, critically analyze them and make recommendations on promising practices for provincial implementation.MethodSemi-structured interviews (42) and focus groups (7) with coordinators of 24 ISGs were used to identify promising practices and confirm their utility with participants.ResultsWe have distributed the ISGs along what we coined an “ISG continuum.” Between teams’ accountability (decentralization) and ISGs’ assumption of responsibility for MAiD requests (centralization), a middle ground approach, focused on the value of support, should be favored.ConclusionThe structuring of ISGs and their practices is intimately linked to their values. Harmonization of ISGs and their practices, while considering their specific values and contexts, can contribute to the equity and quality of services intended for those who request MAiD and those who support them.

Background & Objectives: Patients with bladder outlet obstruction (BOO) due to massive prostate enlargement have several surgical treatment options, such as robot-assisted simple prostatectomy (RASP) and holmium laser enucleation of the prostate (HoLEP). Postoperative outcomes may differ between those undergoing RASP and HoLEP. RASP has been associated with a lower incidence of transient stress urinary incontinence (SUI), while HoLEP allows for shorter catheterization times. Here, we report on our experience with both surgical modalities. Methods: Data were collected from prospectively maintained databases for 37 RASP patients and 181 HoLEP patients treated from July 2021 to November 2023. To control for selection bias, propensity score matching (PSM) was utilized based on age and prostate size. We compared patients’ preoperative, perioperative, and postoperative outcomes both before and after applying PSM. Results: Before the PSM, the median prostate size was significantly lower in the HoLEP group (p < 0.001). The HoLEP group also had significantly shorter operative times (p ≤ 0.001) and lower weights of resected adenoma (p ≤ 0.001). After the PSM of 31 RASP and 31 HoLEP patients, all baseline patient characteristics were comparable. No significant differences were observed in operation time (p = 0.140) or in the weight of resected adenoma (p = 0.394) between the modalities. The median (IQR) length of catheterization was significantly shorter in the HoLEP group (1 [1–4] days) compared to the RASP group (7 [7–8] days), in both pre- and post-matching analyses (p ≤ 0.001 for both), reflecting the standard of practice. In contrast, in both pre- and post-PSM analyses, the average hospital stay was significantly shorter in the RASP cohort, as same-day discharge is standard in our center, whereas the HoLEP cohort required overnight stays due to routine continuous bladder irrigation before discharge (p < 0.001 for all). Notably, the SUI rates and American Urological Association (AUA) symptom scores were comparable at 3 months within both matched and unmatched cohorts (pre-PSM: p = 0.668, p = 0.083; post-PSM: p = 1, p = 0.152, respectively). Conclusions: Our comparative analysis indicates that both RASP and HoLEP yield similar outcomes, including SUI rates, at 3 months. While HoLEP provided shorter durations of postoperative catheterization, RASP offered shorter hospital stays.

Sepsis is the most lethal and expensive condition treated in intensive care units. Sepsis survivors frequently suffer long-term cognitive impairment, which has been linked to the breakdown of the blood–brain barrier (BBB) during a sepsis-associated “cytokine storm”. Because animal models poorly recapitulate sepsis pathophysiology, human models are needed to understand sepsis-associated brain injury and to develop novel therapeutic strategies. With the concurrent emergence of tissue chip technologies and the maturation of protocols for human induced pluripotent stem cell (hiPSC), we can now develop advanced in vitro models of the human BBB and immune system to understand the relationship between systemic inflammation and brain injury. Here, we present a BBB model of the primary barrier developed on the μSiM (microphysiological system enabled by an ultrathin silicon nanomembrane) tissue chip platform. The model features isogenically matched hiPSC-derived extended endothelial culture method brain microvascular endothelial cell-like cells (EECM-BMEC-like cells) and brain pericyte-like cells (BPLCs) in a back-to-back coculture separated by the ultrathin (100 nm) membrane. Both endothelial monocultures and cocultures with pericytes responded to sepsis-like stimuli, with increased small-molecule permeability, although no differences were detected between culture conditions. Conversely, BPLC coculture reduced the number of neutrophils that crossed the EECM-BMEC-like cell monolayer under sepsis-like stimulation. Interestingly, this barrier protection was not seen when the stimulus originated from the tissue side. Our studies are consistent with the reported role for pericytes in regulating leukocyte trafficking during sepsis but indicate that EECM-BMEC-like cells alone are sufficient to maintain the restrictive small-molecule permeability of the BBB.
