RESUMO

One of the World Health Organization's targets for the 2030 viral hepatitis elimination strategy is to reduce new hepatitis C (HCV) infections. In Athens, Greece, people who inject drugs (PWID) have a high HCV prevalence, with increasing trends since the 2000s. This analysis aims to assess primary HCV incidence among PWID during 2012-2020. Two community-based interventions were implemented in 2012-2013 and 2018-2020 with repeated sero-behavioural surveys in each period. Participants enrolled in multiple surveys were identified through linkage. To assess trends in HCV transmission, three indicators were estimated: (i) anti-HCV prevalence among 'new' injectors (those injecting ≤2 years), (ii) indirect HCV incidence among 'new' injectors, assuming infection occurred at the midpoint between initiating injection and the first positive test, and (iii) HCV incidence from repeat participants. There were 431 and 125 'new' injectors, respectively, in 2012-2013 and 2018-2020. Αnti-HCV prevalence [95% CI] declined from 53.6% [48.8%, 58.3%] in 2012-2013 to 40.0% [31.3, 49.1%] in 2018-2020 (25.4% reduction, p = .007). The indirect estimate [95% CI] of HCV incidence among 'new' injectors decreased from 56.1 [49.3, 63.8] to 39.0/100 person-years (PYs) [29.6, 51.5] (30.5% reduction, p = .020). HCV incidence [95% CI] based on seroconversions in repeat participants (16/63 in 2012-2013 and 9/55 in 2018-2020) declined from 64.6 [39.6105.4] to 13.8/100 PYs [7.2, 26.5], respectively (78.6% reduction, p < .001). Primary HCV incidence remains high among PWID in Athens. Consistent implementation of combined interventions, including high-coverage harm reduction programs and initiatives tailored to increase access to HCV treatment, is essential to sustain the declining trends documented during 2012-2020.

RESUMO

BACKGROUND AND AIMS: Hepatitis D virus (HDV) underdiagnosis remains common. We assessed the HDV screening and prevalence rates in HBsAg-positive patients seen at tertiary liver centres throughout Greece as well as factors affecting HDV diagnosis. METHODS: All adult HBsAg-positive patients seen within the last 5 years were included. Non-screened patients who visited or could be recalled to the clinics over a 6-month period were prospectively tested for anti-HDV. RESULTS: Of 5079 HBsAg-positive patients, 53% had anti-HDV screening (41% before and 12% after study initiation). Pre-study (8%-88%) and total screening rates (14%-100%) varied widely among centres. Screening rates were associated with older age, known risk group, elevated ALT, centre location and size and period of first visit. Anti-HDV prevalence was 5.8% without significant difference in patients screened before (6.1%) or after study initiation (4.7%, p = 0.240). Anti-HDV positivity was associated with younger age, parenteral drug use, born abroad, advanced liver disease and centre location. Overall, HDV RNA detectability rate was 71.6% being more frequent in anti-HDV-positive patients with elevated ALT, advanced liver disease and hepatitis B therapy. CONCLUSIONS: Anti-HDV screening rates and recall capabilities vary widely among Greek liver clinics being higher in HBsAg-positive patients of known risk group with active/advanced liver disease seen at smaller centres, while non-medical factors are also important. Anti-HDV prevalence varies throughout Greece being higher in patients born abroad with younger age, parenteral drug use and advanced liver disease. Viremia is more frequently but not exclusively detected in anti-HDV-positive patients with elevated ALT and advanced liver disease.

RESUMO

INTRODUCTION: The Nurses of Hemodialysis Units: it is necessary to face HAIs (hospital-acquired infections) as a "well-tuned" teamwork. The aim of this study was to investigate the perceptions of the teamwork as well as the knowledge attitudes of the nurses of hemodialysis units on infection prevention in Greece. METHODOLOGY: A cross-sectional survey was conducted with a sample of 1018 HCWs (health care workers) of hemodialysis units in Greece. The questionnaires used were: Teamwork Perceptions Questionnaire (T-TPQ) TeamSTEPPS®-Instructor Manual, and questionnaire APPENDIX A. RESULTS: The majority of them were nurses (69.45%) and nurse assistants (23.87%). About teamwork perceptions per factor, we observed uniformity in their responses with very high rates of agreement. The attitudes of nurses of hemodialysis units on the prevention of infections were distinguished in particularly high rates of compliance with a high perception of the risk of transmission of infections with better compliance being that of women. Also, women seem to be more knowledgeable about diseases that mostly affect the pediatric population. It seemed that level of knowledge between the two sexes did not differ regarding HBV (63.16% vs. 66.71%, p = 0.430), HCV (63.91% vs. 66.71%, p = 0.553), HIV infection (78.95% vs. 81.76%, p = 0.471), and influenza (55.64% vs. 59.61%, p = 0.394). CONCLUSIONS: This study highlighted for the first time the high level of perceptions of teamwork of the HCWs of the hemodialysis units in Greece. It is recommended to investigate the correct application of prevention measures and to detect the causes of deviation from good practices with subsequent investigations on hemodialysis units of Greece.

RESUMO

We studied the third coronavirus disease 2019 (COVID-19) pandemic wave in Athens metropolitan area (3 738 901 inhabitants) through two seroepidemiological surveys. Persons presenting in 12 healthcare facilities across Athens in March and June 2021 were studied (764 and 901, respectively). Immunoglobulin G antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein were measured by a chemiluminescent microparticle immunoassay. In March the seroprevalence rate was 11.6%, meaning that 435 208 residents of Athens had evidence of immunity. The respective values in June were 55.7% and 2 082 568 residents. The highest seroprevalence rates attributed to SARS-CoV-2 infection were recorded in persons <18 years (16.3% in March and 31.6% in June), while immunity was mainly vaccine-induced in persons 18-64 years and >65 years. Infection-attributed immunity also increased in older-age groups. Wide ranges in seroprevalence rates were noted across areas in March and June. The highest seroprevalence rates were recorded in Piraeus (47.2%) and West Attica (37.5%). However, the highest increase (>5 times) occurred in Piraeus and the South Section of Athens, which are among the most densely populated areas in Athens. In both study periods, history of COVID-19 or febrile episode, and having a cohabitant with COVID-19 were associated with increased risk for seropositivity among unvaccinated persons (p values <0.001 for all). Residing in Piraeus, the South Section or West Attica was associated with increased risk for seropositivity in June (p values <0.001). Wide heterogeneity in seroprevalence rates was found across areas in Athens, which is mainly attributed to population density. The impact of population mobility and socioeconomic status should be explored.

RESUMO

INTRODUCTION: Although central venous catheters (CVCs) provide reliable vascular access, there are several risks linked with their use, with the rates of central-line-associated bloodstream infections (CLABSIs) being the most important ones. CLABSIs have a big impact on mortality rates and health care costs. The aim of this study was to investigate the incidence of obesity in the development of central venous catheter infections. MATERIAL AND METHOD: This is a prospective, observational study. The data were collected in the ICUs of three major hospitals in Greece, over a period of 18 months. Totally, 744 patients were included in the study. RESULTS: The study included 744 ICU patients aged 63.6 ± 16.6 years. The Apache II score and MODS score of patients were 23.3 ± 6.9 and 7.5 ± 3.8, respectively. Totally, 5.426 catheter-days were included in the study. Among the 722 CVCs, 178 (24.7%) were CLABSIs. The incidence rate of CVC-associated CLABSI was 22.48 infections per 1000 catheter-days. CLABSI was significantly predicted by the BMI (p = 0.001), by the diabetes mellitus as comorbidity (p = 0.013), by the doctors' experience (p = 0.001), by the type of CVC (p = 0.001) and CVC site (p = 0.001), by the number of efforts for CVC insertion (p = 0.009), by the catheterization's duration (p = 0.001) and by the MODS score (p = 0.001). CONCLUSIONS: Better staff training focused on care bundles preventing infections, better medical training focused on less efforts for CVC insertion, and the use of Ultrasounds during the CVC insertion may be the main factors that can lead to lower CLABSI rates in obese patients. Further research relating CLABSI rates in ICU patients and obesity is needed.

RESUMO

BACKGROUND: Viral infections are a significant cause of morbidity and mortality in pediatric transplant populations. We analyzed the epidemiology of viral infections in pediatric hematopoietic stem cell transplant (HSCT) patients, including their incidence, associated risk factors, and outcome. METHODS: In a prospective study from September 2011 to September 2015, blood, urine, and stool specimens were monitored weekly from transplantation to day 100 or after if clinically suspected, by use of real-time polymerase chain reaction. Cytomegalovirus (CMV), Epstein-Barr virus (EBV), BK polyomavirus (BKV), Herpes simplex virus-1,2, Varicella zoster virus, Human herpes virus-6,7, and Adenovirus infections were monitored. All children and adolescents who underwent HSCT received long-term follow up in the regular outpatient clinics (range 2-48 months). RESULTS: A total of 192 HSCTs (autologous/allogeneic: 53/139) were performed in 165 subjects (median age: 5.6 years). Viruses most commonly isolated were CMV (46.1%), BKV (25.9%) and EBV (22.6%) and were more frequent in allogeneic versus autologous transplants (P < 0.05). Almost all high-risk allogeneic recipients developed EBV infections post-HSCT. EBV-PTLD was the only cause of death among those who developed viral disease. The factors significantly associated with the development of viral infections were recipient's advanced age, unrelated donor, mismatched graft and use of peripheral blood stem cells grafts. CONCLUSIONS: Viral infections were common among our pediatric recipients. Data suggest that monitoring of viral load may be significant to the prevention of viral disease. Particular demographic and transplantation characteristics were associated with the development of viral infections post-HSCT.

RESUMO

Recent research evidence has shown that patients with chronic viral hepatitis develop symptoms of anxiety and/or depression, which has a strong impact on their health-related quality of life. This study aimed to assess the levels of anxiety, depression, and health-related quality of life among patients with chronic hepatitis B or C in Greece. It was a cross-sectional study among 111 patients with chronic viral hepatitis, evaluated at a tertiary General Hospital of Athens from March to September of 2014. Anxiety, depression, and health-related quality of life were assessed by the use of specially designed questionnaires. For the comparison between patients' population and general population, a pair-matched population of 111 healthy participants was recruited. Mean age of patients was 44.85 years (SD = 14.4). Fifty-nine patients were infected by hepatitis B virus and 52 by hepatitis C virus. Levels of anxiety and depression were higher among patients than among controls and the overall health-related quality of life was poorer (p < .001). Female gender and liver parenchyma damage were associated with higher levels of anxiety (p < .05). Certain demographic, socioeconomic, and clinical-serological factors were related with higher levels of depression. Poorer health-related quality of life was reported by patients with liver cirrhosis and alanine aminotransferase of 40 IU/L or more. Patients with chronic viral hepatitis demonstrate psychological and physical impairment, especially those with advance liver disease and/or active viral activity.

RESUMO

PURPOSE: The assessment of the level of anxiety, depression and quality of life among patients with heart failure. METHODS: It was an observational study. The populations were 231 patients with heart failure who were hospitalized in cardiology departments of 2 general hospitals in Athens, from September 1, 2010 through January 31, 2012. We used the "Minnesota Living with Heart Failure Questionnaire - MLHFQ" to evaluate patients' quality of life and the " State-Trait Anxiety Inventory - STAI" and the "Maastricht Questionnaire - MQ" to evaluate the level of stress and depression, respectively. RESULTS: The mean age of patients was 66.1±10.1years. The quality of life was poor, since the average score in MLHFQ was 65.4±20.6. Also, patients revealed high levels of both trait and state anxiety (mean score in STAI was 54.5±9.4 and 52.8±8.5 respectively) and depression (mean score in MQ was 34.3±8.4). Factors associated with poor quality of life and high levels of anxiety and depression were older age, low level of education, unemployment, poor economic situation, multiple hospitalizations (> 4 times) and heart failure stages III and IV in NYHA (p<0.001 in all cases). CONCLUSION: Patients with heart failure present severe symptoms of anxiety and depression and poor quality of life. Assessing those patients for these symptoms and providing holistic health care by a multidisciplinary team, will lead to the prevention and early treatment not only of physical but also of the psychosocial manifestations of the disease.

RESUMO

Postoperative fast-track recovery protocols combine various methods to support immediate care of patients who undergo major surgery. These protocols include control of postoperative pain and early beginning of oral diet and mobilization. The combination of these approaches may reduce the rate of postoperative complications and facilitate hospital discharge. The aim of this study was to evaluate progress and parameters of fast-track recovery after major liver and pancreatic resection. A descriptive bibliographical review from 2001 to 2012 via electronic databases such as MEDLINE, PubMed, and Google Scholar was undertaken. Articles that focused on a fast-track protocol were studied. Reports focusing on the implementation of a fast-track protocol in the postoperative recovery of patients after major hepatectomy or pancreatectomy were selected. Fast-track protocols may be applicable to patients recovering after major liver or pancreatic resection. Future research should be focused on particular parameters of the fast-track protocol separately.

RESUMO

AIM: The aim of our study was to evaluate the accuracy of serum biomarkers (AFP/PIVKA-II) and their combination in HCC diagnosis among Caucasian cirrhotic patients. METHODS: Serum AFP/PIVKA-II levels were evaluated in 218 cirrhotics (163 males, 118 CTP-A, 66 ALBI-I, 111 with varices, 63 with diabetes) with (n = 90) or without (n = 128) HCC. Patients with HCC were categorized to BCLC Stage 0/A (n = 12), B (n = 21), C (n = 48), and D (n = 9). RESULTS: The two groups were comparable for all baseline parameters except for age, platelets, and diabetes presence. Median levels of AFP (239.1 vs. 4.0 ng/mL) and PIVKA-II (4082.7 vs. 45.8 mAU/mL) were both significantly higher in HCC group compared to controls (p < 0.001). AUROC and cutoff value for HCC diagnosis were 88%/12.35 ng/mL (AFP) and 84.4%/677.13 mAU/mL (PIVKA-II), whereas their combination showed better diagnostic accuracy (AUROC = 90.2%). The diagnostic accuracy of each biomarker separately was moderate or good in BCLC-0/A/B and was excellent only for BCLC-C patients (AFP: AUROC = 94.3%, cutoff = 12.35 ng/mL and PIVKA-II: 91.3%, 253.51 mAU/mL) whereas their combination presented quite acceptable results in BCLC-B (AUROC = 92.4%) and BCLC-C (AUROC = 95.7%). Excluding HCC patients with high AFP (above 400 ng/mL), the diagnostic accuracy of each biomarker separately and their combination was moderate/good in all groups, except for their combination in BCLC-C (AUROC = 90.5%). CONCLUSIONS: Each biomarker separately showed acceptable accuracy for detecting HCC in cirrhotic patients and excellent for those in BCLC-C stage. The combination of the biomarkers presented excellent results in BCLC-B/C patients. The diagnostic accuracy of PIVKA-II and the combination of the two biomarkers in patients expressing low/non-diagnostic AFP levels was good in BCLC-B and excellent in BCLC-C patients.

RESUMO

BACKGROUND: Mortality among people who inject drugs (PWID) is high, with overdose and HIV infection being the main causes of death. In Greece, there have been no data on mortality, and two HIV outbreaks have been recorded in this population in the past decade. In this study, we aim to estimate the all-cause crude mortality rate and the standardised mortality ratio in this population during 2018-2022. METHODS: PWID recruited from two community-based programs in Athens and Thessaloniki during 2018-2021 were interviewed and tested for HIV/HCV. Data on vital status (deceased/alive) and date of death were obtained from death registries through December 31, 2022. All-cause crude mortality rates (CMR) and standardised mortality ratios (SMR) were estimated. Determinants of mortality were assessed using Cox proportional-hazards model. RESULTS: Of 2,530 participants, 301 died over 8,543 person-years (PYs) of follow-up. The CMR (95 % CI) was 3.52 (3.15-3.94) deaths per 100 PYs; 3.10 per 100 PYs (2.68-3.58) in Athens and 4.48 per 100 PYs (3.74-5.37) in Thessaloniki. An increasing trend in CMR was identified over 2018-2022 in Athens (from 2.90 to 4.11 per 100 PYs, 41.5 % increase, p = 0.018). The pooled SMR (95 % CI) was 15.86 (14.17-17.76) for both cities and was particularly increased in younger individuals, females, those injecting daily, not enrolled to opioid agonist treatment and HIV-infected individuals. Older age, living in Thessaloniki, Greek origin, homelessness, history of injection in the past 12 months, and HIV infection were independently associated with higher risk of death. CONCLUSION: Mortality among PWID in the two largest cities (Athens and Thessaloniki) in Greece in 2018-2022 was high, with the population in Thessaloniki being particularly affected. The increasing trend in mortality in Athens may reflect the long-term impact of the COVID-19 pandemic. Preventive programs such as take-home naloxone, screening and treatment for HIV, are urgently needed.

RESUMO

Resistance to antiviral treatment for chronic hepatitis B virus (HBV) has been associated with mutations in the HBV polymerase region. This study aimed at developing an ultrasensitive method for quantifying viral populations with all major HBV resistance-associated mutations, combining the amplification refractory mutation system real-time PCR (ARMS RT-PCR) with a molecular beacon using a LightCycler. The discriminatory ability of this method, the ARMS RT-PCR with molecular beacon assay, was 0.01 to 0.25% for the different HBV resistance-associated mutations, as determined by laboratory-synthesized wild-type (WT) and mutant (Mut) target sequences. The assay showed 100% sensitivity for the detection of mutant variants A181V, T184A, and N236T in samples from 41 chronically HBV-infected patients under antiviral therapy who had developed resistance-associated mutations detected by direct PCR Sanger sequencing. The ratio of mutant to wild-type viral populations (the Mut/WT ratio) was >1% in 38 (63.3%) of 60 samples from chronically HBV-infected nucleos(t)ide analogue-naive patients; combinations of mutations were also detected in half of these samples. The ARMS RT-PCR with molecular beacon assay achieved high sensitivity and discriminatory ability compared to the gold standard of direct PCR Sanger sequencing in identifying resistant viral populations in chronically HBV-infected patients receiving antiviral therapy. Apart from the dominant clones, other quasispecies were also quantified. In samples from chronically HBV-infected nucleos(t)ide analogue-naive patients, the assay proved to be a useful tool in detecting minor variant populations before the initiation of the treatment. These observations need further evaluation with prospective studies before they can be implemented in daily practice.

RESUMO

The major risk factor of perinatal transmission of Hepatitis B virus (HBV) infection is the level of maternal HBV-deoxyribonucleic acid (DNA) during the third trimester of pregnancy. The primary aim of this study was to evaluate the hematological and biochemical status in Hepatitis B e-antigen (HBeAg)-negative chronic HBV-infected pregnant women and to correlate the findings with the presence or absence of viremia. Ninety-five consecutive chronic HBV-infected pregnant women were evaluated between the 28th and 32nd week of gestation. Viral load was determined by using the COBAS TaqMan HBV test. Sixty-nine women were evaluated and 14 of them exhibited HBV-DNA levels higher than 2000 IU·ml. In this study, viremic women exhibited significantly higher alanine aminotransferase (ALT), creatinine, and uric acid values as well as significantly lower white blood cell count compared with nonviremic women. There was also a significant statistical difference concerning ALT/sodium ratio between viremic and nonviremic women (0.20 ± 0.22 vs. 0.10 ± 0.09, respectively, p= .024). The optimal cutoff points discriminating those women with a high probability to have detectable serum HBV-DNA were 0.092 for ALT/sodium ratio (sensitivity = 73.0%, specificity = 61.5%, area under the receiver operating characteristic curve [AUC] = 71.05%) and 12.8 IU/L for ALT (sensitivity = 73.0%, specificity = 63.0%, AUC = 72.2%). Chronic HBV-infected pregnant women with ALT/sodium ratio ≥ 0.11 had the higher probability of having serum HBV-DNA levels higher than 2000 IU/ml (sensitivity = 76.92%, specificity = 58%, AUC = 62.38%). Presence of HBV-DNA in maternal blood during the third trimester of pregnancy is significantly associated with maternal serum ALT levels in HBeAg-negative chronic HBV-infected pregnant women. Women with an ALT/sodium ratio greater than 0.092 have the higher probability of HBV-DNA presence in maternal blood whereas an ALT/sodium ratio greater than 0.11 could discriminate those women with HBV-DNA levels higher than 2000 IU/ml.

RESUMO

Among the extensive variety of disorders that can cause acute abdominal pain are hepatocellular adenomas (HCAs), pathological entities that otherwise are asymptomatic. Here, we describe a 33-year-old female who presented in the emergency department with acute abdominal pain and a history of liver focal nodular hyperplasia (FNH) diagnosed 10 years ago. An abdominal magnetic resonance imaging (MRI) revealed that the cause of the pain was an intrahepatic hematoma. The mass was surgically removed, and the biopsy revealed inflammatory adenomas, a subtype of HCA. Hepatic adenoma diagnosis remains challenging by clinical and imaging techniques, and usually, a biopsy is the main diagnostic tool. HCA should be differentiated from hepatocellular carcinoma (HCC), FNH, hepatic angioleiomyoma, and hepatic hemangioma. In our case, HCA was misdiagnosed in the past as FNH. HCA rarely may present as acute right abdomen pain, and a potential catastrophic hemorrhage or rupture must be excluded.

RESUMO

Dulaglutide is a once-weekly injectable glucagon-like peptide-1 (GLP-1) receptor agonist that has shown a durable glycemic efficacy as well as beneficial effects on body weight and major adverse cardiovascular events (MACE) outcomes, making it an important option for the treatment of type 2 diabetes. Common side effects of dulaglutide include nausea, diarrhea, and abdominal distension, and these are usually mild to moderate in severity and tend to diminish over time. Morbilliform drug eruptions to dulaglutide are very rare, with only one case reported until now. We report another case of dulaglutide-morbilliform drug eruption to alert the attending physicians that dulaglutide-related adverse skin reactions should be kept in mind as generalized use of dulaglutide and other GLP-1 receptor agonists are expected to remain in widespread clinical use in the future.

RESUMO

BACKGROUND: Tenofovir alafenamide (TAF) has exhibited a favourable safety profile on estimated glomerular filtration (eGFR) and bone mineral density (BMD), but has not been extensively studied in patients with renal impairment and/or BMD disorders. AIMS: To assess predictors of eGFR changes and other safety and efficacy outcomes during 24-month TAF therapy in patients with chronic hepatitis B with renal and/or BMD disorders/risks. METHODS: Adult patients who started TAF at 13 clinics throughout Greece were prospectively included. Main exclusion criteria were hepatitis D, active malignancy and bisphosphonates recent use. MDRD formula was used for eGFR estimation. RESULTS: TAF was initiated in 176 patients (91% switched from another agent). At 12 and 24 months, HBV DNA was undetectable in 97% and 100%, and ALT was normal in 96% and 95% of patients. Median ALT decreased from baseline to month 12/24 (p < 0.001). Mean eGFR decreased from previous treatment initiation to baseline (p < 0.001), increased at 12 months and remained stable at 24 months (p ≤ 0.001). An increase in eGFR of >3 ml/min at 12 month was observed in 50% of patients and was associated mainly with baseline eGFR 30-60 ml/min. In patients with baseline phosphate <2.5 mg/dl, mean serum phosphate increased at month-12/24 (p < 0.001). Median BMD did not change significantly from baseline to 12 months but improved at 24 months (p = 0.001). CONCLUSIONS: In mostly switched patients with renal and/or BMD disorders/risks, eGFR improved after 12-24 months of TAF treatment, especially in patients with baseline eGFR 30-60 ml/min. TAF may also improve low serum phosphate, BMD and ALT, whereas it maintains or induces virological suppression.

RESUMO

Spontaneous preterm birth is the leading cause of perinatal morbidity and mortality. In this study the spontaneous preterm birth rates in a group of hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV)-infected pregnant women without known risk factors for preterm delivery as well as the role of maternal laboratory data and hepatitis B surface antigen/HBV deoxyribonucleic acid (HBV-DNA) in cord blood in respect to preterm labour were evaluated. 138 consecutive HBeAg-negative chronic HBV-infected pregnant women were evaluated during the perinatal period. Serum HBV-DNA was determined by using the Cobas Amplicor HBV Test in both maternal and cord blood samples. 102 women were finally evaluated (36 were excluded) and 15 of them (14.7%) had spontaneous preterm birth. A significant association between spontaneous preterm birth and HBV-DNA in cord blood was observed (p = 0.007). HBV-DNA positivity in cord blood was significantly associated with maternal HBV-DNA levels (p = 0.002). The relative risk of HBV-DNA in cord blood was 6.43 times higher among women with serum HBV-DNA ≥10,000 copies/ml and lymphocyte count <1,500 compared to those with all the other combinations of both parameters (p = 0.001). In conclusion, the presence of HBV-DNA in cord blood is significantly associated with spontaneous preterm birth in chronic HBV-infected pregnant women. Women with HBV-DNA ≥10,000 copies/ml and lymphocyte count <1,500 during the perinatal period have a higher probability of HBV-DNA in their cord blood.

RESUMO

BACKGROUND: Bloodstream Infections (BSIs) in neutropenic patients often cause considerable morbidity and mortality. Therefore, the surveillance and early identification of patients at high risk for developing BSIs might be useful for the development of preventive measures. The aim of the current study was to assess the predictive power of three scoring systems: Infection Probability Score (IPS), APACHE II and KARNOFSKY score for the onset of Bloodstream Infections in hematology-oncology patients. METHODS: A total of 102 patients who were hospitalized for more than 48 hours in a hematology-oncology department in Athens, Greece between April 1st and October 31st 2007 were included in the study. Data were collected by using an anonymous standardized recording form. Source materials included medical records, temperature charts, information from nursing and medical staff, and results on microbiological testing. Patients were followed daily until hospital discharge or death. RESULTS: Among the 102 patients, Bloodstream Infections occurred in 17 (16.6%) patients. The incidence density of Bloodstream Infections was 7.74 per 1,000 patient-days or 21.99 per 1,000 patient-days at risk. The patients who developed a Bloodstream Infection were mainly females (p = 0.004), with twofold time mean length of hospital stay (p < 0.001), with fourfold time mean length of neutropenia (p < 0.001), with neutropenia < 500 (p < 0.001), suffered mainly from acute myeloid leukemia (p < 0.001), had been exposed to antibiotics (p = 0.045) and chemotherapy (p = 0.023), had a surgery (p = 0.048) and a Hickman catheter (p = 0.025) as compared to the patients without Bloodstream Infection. The best cut-off value of IPS for the prediction of a Bloodstream Infection was 10 with a sensitivity of 75% and specificity of 70.9% CONCLUSION: Between the three different prognostic scoring systems, Infection Probability Score had the best sensitivity in predicting Bloodstream Infections.

RESUMO

BACKGROUND: Human papillomavirus (HPV) infection is a causative factor for cervical cancer. Early detection of high risk HPV types might help to identify women at high risk of cervical cancer. The aim of the present study was to examine the HPV prevalence and distribution in cervical smears in a sample of Greek women attending a gynecological outpatient clinic and to explore the determinants of the infection. METHODS: A total of 225 women were studied. All women underwent a regular gynecological control. 35 HPV types were studied; 6, 11, 16, 18, 26, 31, 33, 35, 39, 40, 42, 43, 44, 45, 51, 52, 53, 54, 56, 58, 59, 61, 62, 66, 68, 70, 71, 72, 73, 81, 82, 83, 84, 85 and 89. Also, basic demographic information, sociodemographic characteristics and sexual behavior were recorded. RESULTS: HPV was detected in 22.7% of the study population. The percentage of the newly diagnosed women with HPV infection was 17.3%. HPV-16 was the most common type detected (5.3%) followed by HPV-53 (4.9%). 66.2% of the study participants had a Pap test during the last year without any abnormalities. HPV infection was related positively with alcohol consumption (OR: 2.19, 95% CI: 1.04-4.63, P = 0.04) and number of sexual partners (OR: 2.16, 95% CI: 1.44-3.25, P < 0.001), and negatively with age (OR: 0.93, 95% CI: 0.87-0.99, P = 0.03), and monthly income (OR: 0.63, 95% CI: 0.44-0.89, P = 0.01). CONCLUSION: The prevalence of HPV in women attending an outpatient clinic is high. Number of sexual partners and alcohol consumption were the most significant risk factors for HPV infection, followed by young age and lower income.
