Flexible work arrangements have the potential to enhance work–life balance and contribute to more sustainable work environments. However, they may also increase fatigue and lead to greater work–life conflict (WLC). This study offers a novel contribution by examining the relationship between flexible work arrangements—focusing in particular on the cognitive demands of flexible work (CDFW), which encompass the task structuring, scheduling of working times, planning of working place, and coordination with others—and WLC. Specifically, the study investigates the mediating role of workload in this relationship. Furthermore, it also explores whether perceived organizational support (POS) moderates the indirect relationships between CDFW and WLC, within the framework of the Job Demands-Resources (JD-R) model. Data were collected from a sample of 419 employees in the Italian public sector. The study also controls for potential confounding variables, such as age, gender, duration of employment in public administration, and weekly working hours, to account for their influence on work–life balance and workload. The results highlight a significant positive relationship between planning of the working place and WLC. Additionally, workload plays a mediating role between CDFW subdimensions and WLC. However, POS does not moderate the mediated relationship between CDFW and WLC. Full article

Introduction: Sarcopenia is a systemic condition linked to increased morbidity and mortality in older adults. Point-of-Care Ultrasound (POCUS) offers a rapid, bedside method to assess muscle mass. This study evaluates the diagnostic accuracy of POCUS compared to Dual-energy X-ray Absorptiometry (DXA), the gold standard method, and explores its prognostic value in old patients undergoing surgery for hip fractures. Patients and Methods: In this prospective, single-center study, 126 patients aged ≥ 70 years and hospitalized with hip fractures were included. Sarcopenia was defined according to the revised 2018 EWGSOP2 criteria. Muscle mass was assessed by the Appendicular Skeletal Muscle Mass Index (ASMI) using DXA and by the thickness of the rectus femoris (RF) muscle using POCUS. Results: Of the 126 included patients, 52 had both DXA and POCUS assessments, and 43% of them met the diagnostic criteria for sarcopenia or severe sarcopenia. RF muscle thickness measured by POCUS was significantly associated with ASMI (R² = 0.30; p < 0.001). POCUS showed a fair diagnostic accuracy in women (AUC 0.652) and an excellent accuracy in men (AUC 0.905). Optimal diagnostic thresholds according to Youden’s index were 5.7 mm for women and 9.3 mm for men. Neither RF thickness, ASMI, nor sarcopenia status predicted mortality or major postoperative complications. Conclusions: POCUS is a promising, accessible tool for diagnosing sarcopenia in old adults with hip fractures. Nonetheless, its prognostic utility remains uncertain and should be further evaluated in long-term studies. Full article

Bacterial urinary tract infections (UTIs) are common in small animal practice and their inappropriate treatment contributes to the antimicrobial resistance (AMR) spreading. This study assessed bacterial prevalence, non-susceptibility percentages, antimicrobial prescription and the impact of the application of international guidelines redacted by the International Society for Companion Animals Infectious Disease (ISCAID) in dogs and cats with UTIs evaluated at a European veterinary university hospital, over a 30-month period. A total of 729 bacterial isolates were included. The most frequently isolated bacterial species was Escherichia coli in both dogs (52.8%) and cats (45.7%). Following ISCAID guidelines, almost half of the cases were classified as upper UTIs (24.9%) or recurrent cystitis (24.8%). Multidrug resistance (MDR) percentage was 37.3% (n = 272). Over five semesters, MDR significantly decreased (p = 0.001). Additionally, a significant decrease was recorded for specimens from patients previously treated (p = 0.018) and under treatment at sampling (p < 0.001). Previous treatment with amoxicillin-clavulanate (p = 0.001), marbofloxacin (p < 0.001), enrofloxacin (p < 0.001) and piperacillin-tazobactam (p = 0.016) was linked with higher MDR rates. This study highlighted that companion animals are potential reservoirs for AMR; moreover, international guidelines applied in the daily practice guiding antimicrobial stewardship can lead to a reduction in AMR over time.

Background: Perfectionism is a growing concern among university students, who face high expectations, demanding workloads, and complex academic tasks. These pressures often lead to stress, negatively impacting performance, well-being, and career trajectories. Existing measures of perfectionism and related stress lack focus on their causes and relevance to students. Methods: This study developed and psychometrically tested an inventory assessing the causes (ROOTS), manifestations (MPS-R), and stress (IPSS-R) related to perfectionism. A multicenter cross-sectional online survey was conducted across multiple Italian universities with 469 students. The ROOTS tool was developed, and the MPS and IPSS were adapted following established guidelines. Content validity was examined, and pilot testing was performed. Confirmatory factor analyses tested three-factor models with a second-order factor for each instrument. Construct validity and reliability were also assessed. Results: The ROOTS, MPS-R, and IPSS-R demonstrated strong structural and construct validity, with acceptable reliability. Significant correlations highlighted the interconnectedness of perfectionism’s causes, manifestations, and stress. Conclusions: The Perfectionism Inventory offers a comprehensive tool for identifying causes, manifestations, and consequences of perfectionism in university students. It can help educators and policymakers develop strategies to mitigate its impact on mental health and academic success. Future research should explore its applicability in other populations.

In small animal practice, blood cultures (BCs) are essential for diagnosing bacterial bloodstream infections (BSIs) and guiding targeted antimicrobial therapy, particularly in relation to the rise of multidrug-resistant (MDR) pathogens. This study analyzed 96 positive BCs from dogs and cats at the Veterinary University Hospital (VUH) of Bologna (2020–2024), assessing bacterial prevalence, antimicrobial resistance, and associated risk factors. Escherichia coli was the most common isolate (29/96), followed by Streptococcus canis (11/96). MDR percentage was 29.2% (28/96), with Gram-negatives associated with higher rates (p = 0.040). Nearly half of the cases (46.9%, 45/96) were suspected healthcare-associated infections (HAIs) significantly associated with the number of invasive devices used (p = 0.008) and with the absence of co-positive samples (p = 0.012). Empirical antibiotic therapy was administered in 94.8% (91/96) of cases, with ampicillin–sulbactam and marbofloxacin as the most used drugs. In vitro empirical therapy appropriateness was 76.9% (70/91). MDR was associated with inappropriate empirical therapy (p < 0.001). Mortality within 30 days was 36.5% (35/96), significantly linked to antibiotic escalation (p = 0.006). The findings highlight the need for systematic BC surveillance in veterinary settings to optimize treatment strategies (especially in countries with restrictions on antibiotic use in animals) to mitigate MDR spread and to protect public health.

Glucose-sensing ChREBP and MondoA are transcriptional factors involved in the lipogenic, inflammatory, and insulin signaling pathways implicated in metabolic disorders; however, limited ocular studies have been conducted on these proteins. We aimed to investigate the potential role of ChREBP in the pathogenesis of diabetic retinopathy (DR). We used diabetic human and mouse retinal cryosections analyzed by immunohistochemistry. qRT-PCR was performed to quantify gene expression. To explore the role of ChREBP in rods, we generated caChREBP^RP mice with constitutively active (ca) ChREBP. These mice underwent retinal functional testing, which was followed by proteomic analysis using LC-MS. Furthermore, ARPE-19 cells were infected with lentiviral particles expressing human ChREBP (ARPE-19^ChREBP) and subjected to global proteomics. Our results demonstrate that both proteins were expressed across the retina, although with distinct distribution patterns: MondoA was more prominently expressed in cones, while ChREBP was broadly expressed throughout the retina. Elevated expression of both proteins was observed in DR. This may have contributed to rod photoreceptor degeneration, as we observed diminished scotopic ERG amplitudes in caChREBP^RP mice at P35. The retinal proteomic landscape revealed a decline in the KEGG pathways associated with phototransduction, amino acid metabolism, and cell adhesion. Furthermore, rod-specific caChREBP induced TXNIP expression. Consistent with altered retinal proteomics, ARPE-19^ChREBP cells exhibit a metabolic shift toward increased glyoxylate signaling, sugar metabolism, and lysosomal activation. Our study demonstrates that ChREBP overexpression causes significant metabolic reprogramming triggering retinal functional loss in mice. Full article

Background/Objectives: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of fertile age. Some studies suggest that a ketogenic diet (KD) may have a role in treating PCOS. We aimed to demonstrate the long-term effectiveness of a KD in PCOS. Methods: Eighteen patients with PCOS phenotype A were enrolled: 28% were of normal weight, 28% were overweight, and 44% had obesity. All participants followed a KD without meal replacements for 45 days. After this period, patients underwent gradual carbohydrate reintroduction over 45 days, and thereafter healthy eating indications were given. Twelve patients completed the study. The patients were assessed at baseline and after 6 months. Anthropometric data, body composition, pelvic ultrasound, blood chemistry, hirsutism, and menstrual cycles frequency were recorded; Results: Besides improvement in anthropometric parameters, menstrual cycles (p 0.012), ovarian volume (p 0.029), FSH (p 0.05), LH (p 0.037), and progesterone (p 0.017) improved independently of weight or fat loss. However, testosterone and hirsutism improvements were influenced by weight and fat mass reduction. Conclusions: Our study showed that a KD followed by gradual carbohydrate reintroduction in PCOS has beneficial effects medium term, mostly independent of body weight loss, even in normal-weight women, suggesting that nutritional ketosis exerts beneficial effects per se.

Background: Hormonal, vascular, and behavioral changes during pregnancy can negatively impact a woman’s oral health, resulting in conditions such as gingivitis, dental sensitivity, and caries. Although oral health is critical during pregnancy, it remains frequently overlooked. In this study, the oral health status and hygiene practices of pregnant women attending two university hospitals in southern Italy were evaluated. Methods: A cross-sectional cohort study was conducted with 72 pregnant women. Data were collected through an anonymous questionnaire that evaluated oral hygiene habits, dental visits, and oral pathologies, followed by a clinical examination. The examination included the assessment of the Decayed, Missing, Filled Teeth (DMFT) index and the Oral Hygiene Index (OHI) scores. Results: Among the participants, 61% were in their 9th month of pregnancy. The mean DMFT score was 7.9, and the mean OHI score was 3.6. Only 19.4% of participants had visited a dentist in the past 6 months, while 97.2% reported brushing their teeth just once per day. Gingival bleeding was reported by 72.2% of the women, and 38.9% experienced dental sensitivity, with both conditions worsening during pregnancy. Conclusions: The need for greater oral hygiene education and regular dental care during pregnancy is highlighted in this study. Integrating oral health maintenance into prenatal care programs is essential for preventing pregnancy-related oral diseases and promoting maternal and fetal well-being. Full article

Purpose: The study investigates the role of work-family interface dimensions (negative work-to-family interface, NEGWIF; negative family-to-work interface, NEGFIW; positive work-to-family interface, POSWIF; and positive family-to-work interface, POSFIW) as mediators in the relationship between workload and interpersonal strain. In addition, we examined the moderating effect of gender. Design/methodology/approach: 319 Italian employees working in the commercial sector participants completed a self-report questionnaire. The hypothesized models were tested using PROCESS Macro. Findings: Work–family interface dimensions totally mediated the relationship between workload and interpersonal strain. Moderating influence of gender was found. Gender moderated the relationship between workload and three work–family interface dimensions—NEGWIF, POSWIF and POSFIW—in the indirect relationship between workload and interpersonal strain. Research limitations/implications: This study suggests to organizations that moderate workload and family-friendly policies can act as a protective factor against interpersonal strain. The limitations of the study are the use of self-report measures and the cross-sectional design. Originality/value: This research attempted to fill the gap in interpersonal strain and relationships with the work–family interface. Full article

Cervical cancer is one of the leading causes of mortality in women of reproductive age. In recent years, the development of preventive and therapeutic strategies has significantly increased survival rates. While this represents an important medical achievement, it has also raised a major social issue regarding the need to ensure an adequate quality of life for surviving patients. Many of these women are left without their reproductive capacity at an age when their desire for motherhood has not yet been fulfilled. Infertility or subfertility in cancer survivors is actually a growing problem, complicated by the current trend of increasingly delaying pregnancy. The psychological effects of this issue can be devastating, sometimes even more so than the cancer diagnosis itself. Although today fertility-sparing surgeries can ensure excellent reproductive outcomes with minimal oncological risk, obstetric sequelae remain significant, and affected women often require specialized care pathways. Additionally, adequate counselling is still not provided to all patients who cannot access fertility-sparing treatments and who find themselves without hope. Reproductive medicine is therefore facing the modern challenge of offering concrete options to help these patients realize their desire for motherhood. The aim of this article is to provide an overview of the therapeutic options available to young women facing an early- or later-stage diagnosis of cervical cancer. Full article

Aspergillus terreus has attracted interest due to its application in industrial biotechnology, particularly for the production of itaconic acid and bioactive secondary metabolites. As related species also seem to possess a prosperous secondary metabolism, they are of high interest for genome mining and exploitation. Here, we present draft genome sequences for six species from Aspergillus section Terrei and one species from Aspergillus section Nidulantes. Whole-genome phylogeny confirmed that section Terrei is monophyletic. Genome analyses identified between 70 and 108 key secondary metabolism genes in each of the genomes of section Terrei, the highest rate found in the genus Aspergillus so far. The respective enzymes fall into 167 distinct families with most of them corresponding to potentially unique compounds or compound families. Moreover, 53% of the families were only found in a single species, which supports the suitability of species from section Terrei for further genome mining. Intriguingly, this analysis, combined with heterologous gene expression and metabolite identification, suggested that species from section Terrei use a strategy for UV protection different to other species from the genus Aspergillus. Section Terrei contains a complete plant polysaccharide degrading potential and an even higher cellulolytic potential than other Aspergilli, possibly facilitating additional applications for these species in biotechnology.

Male infertility accounts for approximately 40% of infertility cases. There are many causes of male infertility, including environmental factors, age, lifestyle, infections, varicocele, and cancerous pathologies. Severe oligozoospermia, cryptozoospermia, and azoospermia (obstructive and non-obstructive) are identified as severe male factor infertility, once considered conditions of sterility. Today, in vitro fertilization (IVF) techniques are the only treatment strategy in cases of male factor infertility for which new methodologies have been developed in the manipulation of spermatozoa to achieve fertilization and increase success rates. This review is an update of in vitro manipulation techniques, in particular sperm selection, emphasizing clinical case-specific methodology. The success of an IVF process is related to infertility diagnosis, appropriate choice of treatment, and effective sperm preparation and selection. In fact, selecting the best spermatozoa to guarantee an optimal paternal heritage means increasing the blastulation, implantation, ongoing pregnancy and live birth rates, resulting in the greater success of IVF techniques.

More than 7000 rare diseases affect over 400 million people, posing significant challenges for medical research and healthcare. The integration of precision medicine with artificial intelligence offers promising solutions. This work introduces a classifier developed to discern whether research and news articles pertain to rare or non-rare diseases. Our methodology involves extracting 709 rare disease MeSH terms from Mondo and MeSH to improve rare disease categorization. We evaluate our classifier on abstracts from PubMed/MEDLINE and an expert-annotated news dataset, which includes news articles on four selected rare neurodevelopmental disorders (NDDs)—considered the largest category of rare diseases—from a total of 16 analyzed. We achieved F1 scores of 85% for abstracts and 71% for news articles, demonstrating robustness across both datasets and highlighting the potential of integrating artificial intelligence and ontologies to improve disease classification. Although the results are promising, they also indicate the need for further refinement in managing data heterogeneity. Our classifier improves the identification and categorization of medical information, essential for advancing research, enhancing information access, influencing policy, and supporting personalized treatments. Future work will focus on expanding disease classification to distinguish between attributes such as infectious and hereditary diseases, addressing data heterogeneity, and incorporating multilingual capabilities.

In recent years, Italian Public Administrations (PAs) have swiftly adapted to flexible work arrangements due to the impact of COVID-19. The flexible work has led to addressing new challenges including the need to balance work demands with family commitments, a lack of social support, struggles with inadequate technology, and managing home interruptions that negatively affect home performance. Based on the job demands-resources (JD-R) model, the present study aims at examining the negative impact of home interruptions on smart working performance and the moderating role of two potential job resources: organizational support and perceived quality of the smart working. A convenience sample of 301 Italian public employees engaged in smart working completed an online questionnaire. Multivariate regression analysis results showed that organizational support plays a moderating role in reducing the negative effect of interruptions on home performance. However, the findings did not support a moderating role for the perceived quality of smart working. Overall, these findings highlight the critical role of social factors in buffering the negative effects of smart working, as compared to the quality of the technological arrangements. This information could be valuable for organizations looking to enhance the effectiveness of smart working by focusing on organizational support. Full article

Bombyx mori was domesticated from Bombyx mandarina. The long-term domestication of the silkworm has brought about many remarkable changes to its body size and cocoon shell weight. However, the molecular mechanism underlying the improvement in the economic characteristics of this species during domestication remains unclear. In this study, we found that a transposable element (TE)—Bm1—was present in the upstream regulatory region of the Mlx (Max-like protein X) gene in wild silkworms but not in all domesticated silkworms. The absence of Bm1 caused an increase in the promoter activity and mRNA content of Mlx. Mlx and its partner Mondo belong to the bHLHZ transcription factors family and regulate nutrient metabolism. RNAi of Mlx and Mondo decreased the expression and promoter activity of glucose metabolism-related genes (trehalose transport (Tret), phosphofructokinase (PFK), and pyruvate kinase (PK)), lipogenic genes (Acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS)), and glutamine synthesis gene (Glutamine synthase 2, (GS2)). Furthermore, the transgenic overexpression of Mlx and Mondo in the fat body of silkworms increased the larval body size, cocoon shell weight, and egg number, but the silencing of the two genes resulted in the opposite phenotypes. Our results reveal the molecular mechanism of Mlx selection during domestication and its successful use in the molecular breeding of Bombyx mori. Full article
