Prevalence and associated factors of anxiety and depression in students at a Greek university during COVID-19 lockdown

Background: Restrictions on movement and lockdown are measures taken in many nations, in response to the COVID-19 pandemic. University students are additionally burdened by the transition to distance e-learning. The aims of the study were to investigate the prevalence of anxiety and depression in university students and to identify associated risk factors.Design and Methods: An online questionnaire was administered to 2,009 students in the University of Patras, Greece, during the national lockdown. Socio-demographic, academic data, and the forced disruption of daily life were assessed along with the Greek version of the Hospital Anxiety and Depression Scale.Results: Anxiety and depression prevalence was 35.8% and 51.2% respectively. Age, school of study, financial status, self-perceived health status, level of satisfaction with the state's and university's response and specific aspects in the daily routine were associated with both anxiety and depression scores. At higher odds of both depression and anxiety were students with low income, bad health status, annoyed at staying home and those who encountered difficulties with the online education system. Additional risk factors for depression were studies in humanities and social sciences, and low satisfaction with the university's response, while for anxiety were studies in agricultural sciences and absence of information about COVID-19.Conclusions: The proportion of Greek students showing depression and anxiety, during the restrictive measures, is alarming. Mental health in university students should be monitored. Mitigation strategies should focus on specific personal, academic and social variables that have been identified as protective factors

Viral Causality of Human Cancer and Potential Roles of Human Endogenous Retroviruses in the Multi-Omics Era: An Evolutionary Epidemiology Review

Being responsible for almost 12% of cancers worldwide, viruses are among the oldest known and most prevalent oncogenic agents. The quality of the evidence for the in vivo tumorigenic potential of microorganisms varies, thus accordingly, viruses were classified in 4 evidence-based categories by the International Agency for Research on Cancer in 2009. Since then, our understanding of the role of viruses in cancer has significantly improved, firstly due to the emergence of high throughput sequencing technologies that allowed the “brute-force” recovery of unknown viral genomes. At the same time, multi-omics approaches unravelled novel virus-host interactions in stem-cell biology. We now know that viral elements, either exogenous or endogenous, have multiple sometimes conflicting roles in human pathophysiology and the development of cancer. Here we integrate emerging evidence on viral causality in human cancer from basic mechanisms to clinical studies. We analyze viral tumorigenesis under the scope of deep-in-time human-virus evolutionary relationships and critically comment on the evidence through the eyes of clinical epidemiology, firstly by reviewing recognized oncoviruses and their mechanisms of inducing tumorigenesis, and then by examining the potential role of integrated viruses in our genome in the process of carcinogenesis

Myoepithelial Carcinoma of the Vulva Mimicking Bartholin Gland Abscess in a Pregnant Woman: Case Report and Review of Literature

Myoepithelial tumors of the vulva are extremely rare, with only 8 cases reported in the literature to date. We report the first case of a high-grade myoepithelial vulvar carcinoma diagnosed in a 35-year-old woman during the 27th week of her pregnancy. The patient initially underwent a wide local excision of the lesion but noted rapid regrowth of the vulvar mass during the next 2 months before her delivery. Shortly thereafter, she underwent a classic radical Taussig-Basset total radical vulvectomy, bilateral superficial and deep inguinal groin node dissection, partial vaginectomy, and reconstruction of the vulva. However, the patient rapidly developed both locoregional and distant mestatatic disease, despite aggressive chemoradiotherapy, and she eventually succumbed to disseminated disease almost 20 months after her initial diagnosis

Percutaneous Vertebroplasty in Adult Degenerative Scoliosis for Spine Support: Study for Pain Evaluation and Mobility Improvement

We evaluate the efficacy-safety of percutaneous vertebroplasty (PV) as primary treatment in adult degenerative scoliosis. During the last 4 years, PV was performed in 18 adult patients (68 vertebral bodies) with back pain due to degenerative scoliotic spine. Under anaesthesia and fluoroscopy, direct access to most deformed vertebral bodies was obtained by 13G needles, and PMMA for vertebroplasty was injected. Scoliosis’ inner arch was supported. Clinical evaluation included immediate and delayed studies of patient’s general condition and neurological status. An NVS scale helped assessing pain relief, life quality, and mobility improvement. Comparing patients’ scores prior to (mean value 8.06±1.3 NVS units), the morning after (mean value 3.11±1.2 NVS units), at 12 (mean value 1.67±1.5 NVS units), and 24 months after vertebroplasty (mean value 1.67±1.5 NVS units) treatment, patients presented a mean decrease of 6.39±1.6 NVS units on terms of life quality improvement and pain relief (P=0.000). Overall mobility improved in 18/18 (100%) patients. No complications were observed. During follow-up period (mean value 17.66 months), all patients underwent a mean of 1.3 sessions for facet joint and nerve root infiltrations. Percutaneous vertebroplasty in the inner arch seems to be an effective technique for supporting adult degenerative scoliotic spine

Real-World Use and Adverse Events of SARS-CoV-2 Vaccination in Greek Patients with Inflammatory Bowel Disease

Since inflammatory bowel disease (IBD) patients were excluded from vaccine authorization studies, limited knowledge exists regarding perceptions and unfavorable effects of COVID-19 vaccination in this group. We aimed to investigate the real-world use and adverse events (AEs) of COVID-19 vaccines in Greek IBD patients. Fully vaccinated IBD patients followed in Greek centers were invited to participate. All patients filled out an anonymous online survey concerning the vaccination program, which included information regarding demographics, clinical characteristics, treatment, vaccination perceptions and potential AEs. Overall, 1007 IBD patients were included. Vaccine hesitancy was reported by 49%. Total AEs to vaccination were reported by 81% after dose 1 (D1) and 76% after dose 2 (D2), including isolated injection site reactions (36% and 24% respectively). Systemic AEs were more common after D2 (51%, D2 vs. 44%, D1, p < 0.0001). Very few patients reported new onset abdominal symptoms (abdominal pain 4% (D1), 6% (D2) and diarrhea 5% (D1), 7% (D2)). There were no serious AEs leading to emergency room visit or hospitalization. In multivariate analysis, AEs occurrence was positively associated with young age and female gender (p < 0.0005 for both doses), whereas inactive disease was negatively associated with AE in D1 (p = 0.044). SARS-CoV-2 vaccination in Greek IBD patients demonstrated a favorable and reassuring safety profile

Manganese disulfide-silicon dioxide nano-material: synthesis, characterization, photocatalytic, antioxidant and antimicrobial studies

The sol-gel/ultrasonically rout produced the novel MnS2-SiO2 nano-hetero-photocatalysts with the various ratio of MnS2. Prepared nano-catalyst were investigated in the photo-degradation of methylene blue under UV light illumination. Structural and optical attributes of as-prepared nano-catalysts were evaluated by X-ray diffraction and photoelectron spectroscopy. The morphological were studied by scanning electron microscopy-EDS, and dynamic light scattering. The diffuse reflectance spectroscopy was applied to examine the band gap energy. The Eg values of SiO2, MnS2-SiO2–0, MnS2-SiO2–1, and MnS2-SiO2–2 nanocomposites are 6.51, 3.85, 3.17, and 2.67 eV, respectively. The particle size of the SiO2 and MnS2-SiO2–1 nanocomposites were 100.0, and 65.0 nm, respectively. The crystallite size values of MnS2-SiO2–1 were 52.21 nm, and 2.9 eV, respectively. MnS2-SiO2 nano-photocatalyst was recognized as the optimum sample by degrading 96.1% of methylene blue from water. Moreover, the influence of pH of the solution, and contact time as decisive factors on the photo-degradation activity were investigated in this project. The optimum data for pH and time were found 9 and 60 min, respectively. The photo-degradation capacity of MnS2-SiO2–2 is improved (96.1%) due to the low band gap was found from UV–vis DRS. The antimicrobial data of MnS2-SiO2 were studied and demonstrated that the MnS2-SiO2 has fungicidal and bactericidal attributes
