Knowledge and Attitudes of Medical and Nursing Students in a Greek University Regarding Sexually Transmitted Diseases.

AIMS AND OBJECTIVES: the present study aimed to assess the knowledge and attitudes of medical and nursing students at the University of Patras, western Greece, regarding sexually transmitted infections (STIs), sexual behavior and STI prevention measures, as well as the level of future healthcare professionals' education. METHOD: A descriptive, cross-sectional study was conducted. A total of 231 medical and nursing students (n = 106 medical, and n = 125 nursing) completed and returned the pre-tested study questionnaire. RESULTS: Most participants (77.5%) were females and46.1% were in the age group of 18-21 years. Syphilis, HIV/AIDS, and Hepatitis B were regarded as STIs by 65.8% of them. Medical students could predominantly list the widely known STIs compared to nursing students (p = 0.004). Regarding HIV/AIDS, 72.7% of the respondents reported that it is transmitted sexually and through blood transfusion. However, medical students were better informed than nursing students (p = 0.001). Medical students as well as students in the final year of their studies were found to be better informed about the vaccines available to prevent STIs. Regarding the question about what constitutes a risky sexual behavior, 71.4% answered sexual intercourse without the use of condom and 18.6% indicated having sex with an unknown partner. Most participants (69.7%) were satisfied with the education provided by their institution and no statistically significant difference was observed between medical and nursing students. Almost all students (97.8%) agreed that the course/subject of sex education must be included in school programs. CONCLUSIONS: A comprehensive analysis of knowledge and attitudes of Greek medical and nursing students regarding STIs, prevention measures and education level was conducted. The results of the present study could assist in the development of targeted training courses that can improve healthcare professionals' knowledge and ability to manage STIs.

The impact of frailty and illness perceptions on quality of life among people living with HIV in Greece: A network analysis.

OBJECTIVE: Despite the significant advances in healthcare, people living with HIV still face challenges that affect their quality of life (QoL), both in terms of their physical state as represented by frailty and of their illness perceptions (IP). The aim of this study was to unravel the associations between these constructs (QoL, frailty, IP). METHODS: This multicenter, cross-sectional study included 477 people living with HIV (93% male; median age = 43 years, IQR = 51.7) from six HIV clinics in Greece. Frailty phenotype, QoL and IP were assessed using Fried's criteria, EuroQoL (EQ-5D-5L) and Brief Illness Perception Questionnaire (BIPQ), respectively. Network analysis model was utilized. RESULTS: Among frailty criteria, exhaustion had the highest expected influence, while the strongest correlation concerns exhaustion and weak grip strength (pr = 0.14). Regarding the QoL items, usual activities displayed the highest expected influence. The correlations of pain/discomfort with mobility (pr = 0.31), and usual activities with self-care (pr = 0.34) were the strongest. For the BIPQ items, the strongest correlation was found between illness concern and emotional response (pr = 0.45), whereas the latter item was the one that displayed the highest expected influence. Three communities were formed: 1) personal control, treatment control and coherence, 2) the frailty items with mobility, self-care, usual activities, and pain/discomfort, and 3) the rest BIPQ items with anxiety/depression. Identity displayed the highest bridge strength, followed by pain/discomfort, usual activities and consequences. CONCLUSIONS: The interplay between QoL, frailty, and IP in people living with HIV requires clinical attention. Self-reported exhaustion, slow walking speed, and low physical activity affect the physical QoL dimensions, while anxiety/depression is strongly associated with illness-related concern and perceived emotional effects, leading to psychological distress. Symptom management can improve QoL, and information on the disease and treatment can enhance control over the disease. Developing interventions to address QoL, frailty, and IP is crucial.

Mapping frailty in people living with HIV: A nationwide study in Greece.

OBJECTIVES: Frailty is known to affect people living with HIV prematurely, compared to the ageing seronegative population. In this cross-sectional study, we aimed to assess frailty prevalence in people living with HIV in Greece and find associations of frailty criteria with clinical data. METHODS: Demographic and clinical data were collected from 477 participants in six HIV clinics. Fried's frailty phenotype was used to assess frailty prevalence, and participants were classified as frail, pre-frail or robust. Associations of several factors with overall frailty phenotype, as well as with frailty criteria, were explored. RESULTS: The median age was 43 years old (IQR = 51.5) and 444/477 (93%) were men. Most of the participants (429/477, 93.5%) had an undetectable HIV viral load, and a CD4 cell count over 500 cells/µl (366/477, 76.7%). Frailty assessment classified 285/477 (62.1%) as robust, 155/477 (33.8%) as pre-frail and 19/477 (4.1%) as frail. Weakness in grip strength was the most prevalent criterion (128/477, 26.8%), followed by exhaustion (46/477, 9.6%). Lower CD4 cell count, history of AIDS diagnosis, CNS disorders, psychiatric diagnoses, and polypharmacy were strongly associated with frailty. CONCLUSIONS: Although the prevalence of frailty in people living with HIV in Greece is uncommon, when combined with pre-frailty over a third of people are affected, which requires attention in clinical practice. The physical and psychological aspects of frailty highlight the need for a holistic approach to prevent or counteract it. The diverse associations of frailty criteria with HIV-related and non-HIV-related factors suggest a possible variation in people's different healthcare needs.

Kyrieleis Arteriolitis Associated with Acute Retinal Necrosis due to Herpes Simplex Virus Type 1 Secondary to Herpetic Encephalitis.

We report the case of a 52-year-old woman who presented to the emergency department with acute retinal necrosis in her left eye secondary to herpes simplex virus type 1 encephalitis for which she had been hospitalized four months before. Treatment with intravitreal foscarnet and intravenous acyclovir was promptly commenced followed by the addition of oral prednisolone. PCR analysis of aqueous humor detected HSV type 1 DNA. The condition responded to therapy with partial resolution of intraocular inflammation and improvement of visual acuity, but the presence of Kyrieleis plaques was observed two weeks after the initiation of treatment, when five intravitreal foscarnet injections had been administered. The patient was switched to oral therapy with valacyclovir, and 10 weeks after commencing treatment, the patient's left eye was free of inflammation, having achieved a BCVA of 20/20. Oral steroid treatment was gradually tapered off, and the patient was instructed to remain on prophylactic antiviral therapy. Kyrieleis arteriolitis is an uncommon finding in the context of acute retinal necrosis. As far as we are aware, we report the first case of Kyrieleis arteriolitis in acute retinal necrosis secondary to viral encephalitis and the second one presenting Kyrieleis plaques in acute retinal necrosis caused by herpes simplex virus type 1. Prior reports of cases of Kyrieleis arteriolitis in acute retinal necrosis are also presented.

Treatment of Prosthetic Joint Infection due to Listeria Monocytogenes. A Comprehensive Literature Review and a Case of Total Hip Arthroplasty Infection.

As reported in contemporary literature, prosthetic joint infection (PJI) caused by Listeria monocytogenes (LM) is a rare infection affecting mainly immunocompromised patients. It is considered a late complication occurring months or years after the arthroplasty that is treated with, or without, implant retention, in one-stage or two-stage surgical procedures, and long-term administration of antibiotics. We reviewed the published studies in the English language and present a case of a patient who underwent total hip arthroplasty (THA) and had been affected by this infection. Our patient was successfully treated with 3 months of antibiotics (ampicillin and TMP/SMX) and a two-stage surgical procedure. The success rates of conservative treatment and one-stage or two-stage procedures are dependent on appropriate patient selection and chronicity of the infection. Ιmmmunocompromised patients are susceptible to PJI caused by LM and should be advised that consumption of unpasteurized dairy products increases the risk of this atypical infection.

Varicella-zoster virus aseptic meningitis: an atypical presentation in an immunocompetent male patient.

Varicella-zoster virus (VZV) reactivation causes a relatively common disease in immunocompromised patients characterized by rash and radiating pain. Aseptic meningitis is a rare complication of VZV infection and commonly is associated with exanthem and neurological signs. We present an atypical case of VZV meningitis in a healthy 56-year-old male who was initially presented with persistent headache as the only symptom. Anti-VZV immunoglobulin G titer both in serum and in cerebrospinal fluid (CSF) and the polymerase chain reaction (PCR) CSF analysis revealed VZV infection. Our case highlights the importance of considering VZV aseptic meningitis in immunocompetent individuals even in the absence of the typical presentation of meningitis. Screening techniques such as CSF, PCR as well as anti-VZV antibodies in CSF show that VZV meningitis is a common cause of aseptic meningitis and allows the early recognition of CNS involvement in the VZV infection.

Catheter-related bloodstream infections: catheter management according to pathogen.

Central-line access is an essential part of modern healthcare practice; however, catheter-related bloodstream infection is a major problem that causes substantial morbidity and mortality, and excess length of stay and cost. The risk of infection depends on the type of device, the site of insertion, the underlying conditions and the appropriate prevention measures taken during catheter insertion. Management of catheter-related bloodstream infection involves deciding on catheter removal, antimicrobial catheter lock solution and the type and duration of systemic antimicrobial therapy. Systemic antimicrobial use is essential but, although generally effective in controlling sepsis, it often fails to sterilise the line, increasing the incidence of complications or recurrence. The decision regarding whether the catheter should be removed or retained is therefore crucial. One of the major factors to be considered is the type of organism involved in the catheter-related infection. This review outlines the epidemiology, pathogenesis, diagnosis, microbiology and management of catheter-related infections, mainly focusing on the management of the intravascular device according to the pathogen.

Stress-induced hyperglycemia in patients with severe sepsis: a compromising factor for survival.

OBJECTIVE: To study the clinical and laboratory characteristics of patients with severe sepsis and baseline hyperglycemia and investigate the impact of hyperglycemia on the final outcome. PATIENTS: A total of 265 patients admitted with severe sepsis in 3 major hospitals in South-Western Greece, during a 1-year period, were included in the study. Patients were divided in 3 groups according to their glycemic profile at admission: patients with stress hyperglycemia (group SH, n=47), with diabetes mellitus (group DM, n=65), and with normal glucose level (group NG, n=153). Hyperglycemia was defined as an admission or in-hospital fasting glucose level of >or=126 mg/dL or a random blood glucose level of >or=200 mg/dL on >or=2 determinations. RESULTS: A total of 42.2% of patients with severe sepsis had baseline hyperglycemia with 17.7% having sepsis-induced stress hyperglycemia. No family history was noted in the SH group. A higher percentage of septic patients with stress hyperglycemia died compared with patients with normal glucose levels (42.5% versus 13.7%) and diabetics (42.5% versus 24.6%). Group DM had also a poorer prognosis than group NG (24.6% versus 13.7%). A positive correlation was detected between the fasting blood glucose levels of group SH and the severity of sepsis indicated by sepsis-related organ failure assessment score. CONCLUSION: Baseline hyperglycemia, including stress-induced hyperglycemia, is common in patients with severe sepsis. Stress-induced hyperglycemia is related to a more severe disease and poorer prognosis.

Cytokine production and hospital mortality in patients with sepsis-induced stress hyperglycemia.

OBJECTIVES: To investigate whether stress hyperglycemia affects the production of the main pro- and anti-inflammatory cytokines and the 28-day hospital mortality in patients with severe sepsis. METHODS: The study included 62 patients with severe sepsis, divided in three groups according to their glycemic profile within 24h after admission: patients with stress hyperglycemia (group SH, n=16), diabetes mellitus type II (group DM, n=27), and normal glucose levels (group NG, n=19). The serum levels of the cytokines TNF-alpha, IL-6, IL-10 and TGFbeta-1 were measured within 24h after admission. RESULTS: A higher percentage of septic patients with stress hyperglycemia died compared to diabetic patients (43.7 vs. 14.8%) and group NG (43.7 vs. 5.2%). Group SH had higher SOFA score and levels of IL-6 and IL-10 than group DM and group NG. It also had higher levels of TNF-alpha than group DM but not group NG. There was no difference in the levels of TGFbeta-1 among the three groups. Non-survivors had higher levels of IL-10, no difference was detected for IL-6, TNF-alpha, IL-10/TNF-alpha ratio and TGFbeta-1. Interleukin-10 values, mean fasting glucose values and age were found as prognostic factors associated with outcome. CONCLUSIONS: Stress hyperglycemia is associated with increased cytokine production and an adverse clinical outcome in patients with severe sepsis.
