Abstract
This historical epidemiological study evaluates sexually transmitted infections (STIs) among Greek refugees during the Interwar period in the region of Imathia, Central Macedonia, Greece, as a part of the effort against sexually transmitted infections in Greece (1910-1940). We examined the archives of the Refugee Hospital of Veroia - the capital of the regional unit of Imathia (March 5, 1926 to October 27, 1940). This is a report of previously unpublished primary material comprising a cohort of 15,921 cases, among whom 41 patients were hospitalized on account of syphilis and 19 on account of gonococcal infection. Descriptive statistics were estimated. Primary (n=4), secondary (n=2), tertiary (n=13), congenital (n=7), and not further specified (n=15) cases of syphilis were identified, whereas a variety of differential diagnosis problems arose. Syphilis and gonococcal infection/gonorrhea seemed to affect various social groups, as evidenced by the variety of professions involved. Refugee patients originated from various areas such as Caucasus, Thrace, Constantinople, Bithynia, and Pontus. Lack of information and poor healthcare led to spreading of STIs in Greece. Law 3032/1922 was crucial for the Greek effort against sexually transmitted infections.

Anti-SARS-CoV-2 Antibody Responses in Convalescent Plasma Donors Are Increased in Hospitalized Patients; Subanalyses of a Phase 2 Clinical Study. Microorganisms 2020; 8:microorganisms8121885. [PMID: 33260775 PMCID: PMC7760522 DOI: 10.3390/microorganisms8121885] [Citation(s) in RCA: 34] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 11/20/2020] [Accepted: 11/27/2020] [Indexed: 02/07/2023] Open
Abstract
We evaluated the antibody responses in 259 potential convalescent plasma donors for Covid-19 patients. Different assays were used: a commercial ELISA detecting antibodies against the recombinant spike protein (S1); a multiplex assay detecting total and specific antibody isotypes against three SARS-CoV-2 antigens (S1, basic nucleocapsid (N) protein and receptor-binding domain (RBD)); and an in-house ELISA detecting antibodies to complete spike, RBD and N in 60 of these donors. Neutralizing antibodies (NAb) were also evaluated in these 60 donors. Analyzed samples were collected at a median time of 62 (14-104) days from the day of first symptoms or positive PCR (for asymptomatic patients). Anti-SARS-CoV-2 antibodies were detected in 88% and 87.8% of donors using the ELISA and the multiplex assay, respectively. The multivariate analysis showed that age ≥50 years (p < 0.001) and need for hospitalization (p < 0.001) correlated with higher antibody titers, while asymptomatic status (p < 0.001) and testing >60 days after symptom onset (p = 0.001) correlated with lower titers. Interestingly, pseudotype virus-neutralizing antibodies (PsNAbs) significantly correlated with spike and with RBD antibodies by ELISA. Sera with high PsNAb also showed a strong ability to neutralize active SARS-CoV-2 virus, with hospitalized patients showing higher titers. Therefore, convalescent plasma donors can be selected based on the presence of high RBD antibody titers.

Abstract
Objectives This Historical Epidemiological study aims to evaluate malaria in Greek refugees during the 1926-1940 period in the region of Imathia, Central Macedonia, Greece, in the context of the Anti-Malaria Battle in Greece. Materials and methods The archives of the Refugee Hospital of Veria, Imathia were examined (March 5, 1926 to October 27, 1940); this is a report of previously unpublished primary material comprising 15,921 cases, of whom 8,408 patients were hospitalized due to malaria. Multivariate logistic regression analysis was performed to identify independent risk factors for hospitalization due to malaria; adjusted odds ratios (ORs) and 95% Confidence Intervals (CIs) were estimated. Results Residence in lower elevation (adjusted OR = 0.95, 95% CI: 0.92-0.97, per increments of elevation), refugee status (from Bulgaria/Balkans, Caucasus, Constantinople and Thrace, Pontus and inland of Turkey), female gender, and younger age (adjusted OR per 10-year increase = 0.88, 95% CI: 0.86-0.90) correlated independently with hospitalization due to malaria. Conclusions Malaria was the leading cause of admission to the hospital in the region of Imathia during the studied period. The association with elevation reflects the aggravating role of marshes before the drainage of Lake Giannitsa.

Abstract
The prospective observational cohort study COMPASS-COVID-19 aimed to develop a risk assessment model for early identification of hospitalized COVID-19 patients at risk for worsening disease. Patients with confirmed COVID-19 (
n
= 430) hospitalized between March 18 and April 21, 2020 were divided in derivation (
n
= 310) and validation (
n
= 120) cohorts. Two groups became evident: (1)
good prognosis group
(G-group) with patients hospitalized at the conventional COVID-19 ward and (2)
Worsening disease group
(W-group) with patients admitted to the intensive care unit (ICU) from the emergency departments. The study end point was disease worsening (acute respiratory failure, shock, myocardial dysfunction, bacterial or viral coinfections, and acute kidney injury) requiring ICU admission. All patients were routinely evaluated for full blood count, prothrombin time, fibrinogen, D-dimers, antithrombin (AT), and protein C activity. Data from the first hospitalization day at the conventional ward or the ICU were analyzed. Cardiovascular risk factors and comorbidities were routinely registered. Obesity, hypertension, diabetes and male gender, increased fibrinogen and D-dimers, thrombocytopenia, AT deficiency, lymphopenia, and an International Society on Thrombosis and Haemostasis (ISTH) score for compensated disseminated intravascular coagulation score (cDIC-ISTH)
≥
5 were significant risk factors for worsening disease. The COMPASS-COVID-19 score was derived from multivariate analyses and includes obesity, gender, hemoglobin, lymphocyte, and the cDIC-ISTH score (including platelet count, prothrombin time, D-dimers, AT, and protein C levels). The score has a very good discriminating capacity to stratify patients at high and low risk for worsening disease, with an area under the receiver operating characteristic curve value of 0.77, a sensitivity of 81%, and a specificity of 60%. Application of the COMPASS-COVID-19 score at the validation cohort showed 96% sensitivity. The COMPASS-COVID-19 score is an accurate clinical decision-making tool for an easy identification of COVID-19 patients being at high risk for disease worsening.

Abstract
COVID‐19 is a systemic infection with a significant impact on the hematopoietic system and hemostasis. Lymphopenia may be considered as a cardinal laboratory finding, with prognostic potential. Neutrophil/lymphocyte ratio and peak platelet/lymphocyte ratio may also have prognostic value in determining severe cases. During the disease course, longitudinal evaluation of lymphocyte count dynamics and inflammatory indices, including LDH, CRP and IL‐6 may help to identify cases with dismal prognosis and prompt intervention in order to improve outcomes. Biomarkers, such high serum procalcitonin and ferritin have also emerged as poor prognostic factors. Furthermore, blood hypercoagulability is common among hospitalized COVID‐19 patients. Elevated D‐Dimer levels are consistently reported, whereas their gradual increase during disease course is particularly associated with disease worsening. Other coagulation abnormalities such as PT and aPTT prolongation, fibrin degradation products increase, with severe thrombocytopenia lead to life‐threatening disseminated intravascular coagulation (DIC), which necessitates continuous vigilance and prompt intervention. So, COVID‐19 infected patients, whether hospitalized or ambulatory, are at high risk for venous thromboembolism, and an early and prolonged pharmacological thromboprophylaxis with low molecular weight heparin is highly recommended. Last but not least, the need for assuring blood donations during the pandemic is also highlighted.

Abstract
PURPOSE The purpose of this study was to investigate retinal layers' changes in patients with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (anti-VEGF) agents and to evaluate if these changes may affect treatment response. METHODS Participants in this prospective study were 110 treatment-naïve patients with center involved DME, who were treated with anti-VEGF agents and followed up for at least 12 months. A qualitative and quantitative analysis of retinal layers that can affect visual acuity was performed. Patients with persistent DME were defined, and factors which could affect this outcome were determined. RESULTS Visual acuity was significantly improved, while there was also a statistically significant reduction in central retinal thickness and in all separate retinal layers' thickness at month 12 compared to baseline (p < 0.001). Visual acuity was associated with central retinal thickness and outer retinal layers' thickness;51.8% of the patients presented with persistent DME at month 12, which was found to be significantly associated with baseline visual acuity and HbA1C levels. CONCLUSIONS Anti-VEGF treatment is effective in reducing retinal thickness as a whole and in all separate retinal layers at 12-month follow-up in patients with DME. Changes in central retinal thickness and in outer retinal layers were found to affect visual acuity. HbA1c was the most significant factor to determine persistence of DME at month 12.

Abstract
PURPOSE To investigate whether women with unexplained infertility (UI) demonstrate different demographic and IVF characteristics compared to those with other causes of infertility. METHODS Data on 245 couples that underwent a total of 413 IVF/ICSI cycles were analyzed (UI 114 cycles, 73 women; anovulation (PCO/PCOS) 83 cycles, 51 women; tubal factor 85 cycles, 47 women; male factor 131 cycles, 74 women). Features of UI were compared versus other infertility groups, after adjustment for multiple comparisons. Generalized least squares (GLS) and random-effects logistic regression analysis were also performed. RESULTS Live birth rates, consisting of the primary outcome, were similar in all compared infertility groups. Compared to male infertility, UI was associated with woman's older age at cycle, lower body mass index (BMI), and higher follicle-stimulating hormone (FSH). Compared to tubal infertility, UI was linked to lower endometrial thickness at oocyte retrieval and lower BMI; compared to anovulatory infertility related to PCO/PCOS, UI was linked to woman's older age, more frequent smoking, and poorer ovarian reserve tests (FSH and antral follicle count). After adjustment for other types of infertility, woman's age, age at menarche, and FSH levels, anovulatory infertility presented with higher odds of clinical pregnancy compared to UI (adjusted OR = 2.13, 95% C: 1.01-4.52). CONCLUSIONS Infertile women with UI undergoing assisted reproduction demonstrate different demographic and clinical characteristics compared to those of other causes of infertility, albeit live birth rates are similar.

Abstract
Various agents are currently under evaluation as potential treatments in the fight against coronavirus disease 2019 (COVID-19). Plasma from patients that have overcome COVID-19 infection, referred to as convalescent plasma, is a treatment option with considerable background in viral diseases such as Spanish influenza, H1N1, Ebola, Severe Acute Respiratory Syndrome (SARS), and Middle East Respiratory Syndrome (MERS). Although convalescent plasma has historically proven beneficial in the treatment of some viral diseases, its use is still explorative in the context of COVID-19. To date, preliminary evidence from case series is favorable as significant clinical, biochemical improvement and hospital discharge have been reported. A detailed overview of randomized as well non-randomized trials of treatment with convalescent plasma, which have been registered worldwide, is provided in this review. Based on these studies, data from thousands of patients is anticipated in the near future. Convalescent plasma seems to be a safe option, but potential risks such as transfusion-related acute lung injury and antibody-dependent enhancement are discussed. Authorities including the Food and Drug Administration (FDA), and scientific associations such as the International Society of Blood Transfusion (ISBT) and the European Blood Alliance (EBA), have provided guidance into the selection criteria for donors and recipients. A debatable, pivotal issue pertains to the optimal timing of convalescent plasma transfusion. This treatment should be administered as early as possible to maximize efficacy, but at the same time be reserved for severe cases. Emerging risk stratification algorithms integrating clinical and biochemical markers to trace the cases at risk of significant deterioration can prove valuable in this direction.

Abstract
The presence of malignant squamous cells in pancreatic cytopathology is a rare phenomenon that results either from a primary or a metastatic process. Pancreatic adenosquamous carcinoma (PASC) represents the most common variant of pancreatic ductal adenocarcinoma and is associated with a dismal prognosis. Within the period of 2013-2018, the archives of "Hygeia and Mitera Hospital" were searched for pancreatic cytopathology-related diagnoses that included the interpretation of "malignant squamous cells present." All fine needle aspirations (FNAs) of pancreatic lesions, including liver metastases in patients with known pancreatic primaries, were retrieved along with their relevant clinical information. Five pancreatic and two liver FNAs acquired from a total of six patients were reexamined. None of these patients had any documented history of primary squamous malignancy elsewhere. All pancreatic and one of the two liver FNAs showed malignant squamous cells, identified based on either morphology or immunochemistry. The other liver FNA represented a metastatic deposit which comprised of only a glandular component, whereas the associated pancreatic FNA exhibited both squamous and glandular counterparts. Most cases characteristically showed necrosis and keratinization. Of interest, two cases revealed the presence of tumor-associated giant cells. In conclusion, the presence of malignant squamous cells in pancreatic FNAs could mean the presence of PASC, especially when there is no documented history of a primary malignancy and a complete clinical and imaging workup has been performed. Immunochemistry on cell block material could help to confirm squamous differentiation in the absence of overt keratinization.

Abstract
BACKGROUND The goal of this systematic review is to synthesize the published meta-analyses assessing the role of nutritional, behavioral and physical activity factors/interventions on the prevention or treatment of pediatric and adolescent obesity. METHODS An online search was conducted in PubMed (end-of-search: September 30, 2015); English-language meta-analyses pooling observational and/or interventional studies examining weight-related indices on children and adolescents were included. RESULTS Sixty-six meta-analyses corresponding to more than 900,000 children and adolescents were retrieved. The majority of meta-analyses included interventional studies most of which referred to mixed or combined interventions, including components such as diet, physical activity and sedentary behavior reduction. Discrepancies between meta-analyses on observational and interventional studies were noted. Combined interventions including physical activity and nutritional modifications seemed to represent the most effective means for tackling childhood obesity. CONCLUSIONS Synthesis of interventional or observational evidence may yield discrepant results. The combination of enhanced physical activity and improved nutrition emerged as a promising intervention in the fight against childhood/adolescent obesity. However, further research is needed about the most effective multidimensional prevention strategy.

Abstract
Aim: The purpose of this study is to evaluate the role of MET T1010I and MET rs40239 as potential risk factor and/or prognostic markers in patients with triple-negative breast cancer (TNBC). Methods: 114 samples of DNA from paraffin-embedded breast normal tissues of patients with TNBC and 124 samples of healthy controls were collected and analyzed for MET T1010I and MET rs40239 polymorphisms. Results: MET T1010I CT genotype was associated with increased risk of TNBC in both univariate and multivariate analysis. The status of rs40239 was not associated with a higher risk for TNBC at either the univariate or the multivariate analysis. None of the examined polymorphisms was associated with overall survival at the univariate or multivariate Cox regression analysis (adjusted HR=1.35, 95% CI: 0.31–5.97 for MET T1010I CT/TT vs CC; adjusted HR=1.78, 95% CI: 0.73–4.35 for rs40239 AG/GG vs AA). Conclusion: Our case–control study suggests that MET T1010I seems to be a risk factor for TNBC in the Caucasian Greek population, in contrast with MET rs40239, where no correlation was found.

Abstract
Reactive oxygen species have a key role in liver ischemia-reperfusion (I/R) injury. In the present study, the effect of the anti-oxidant compound lazaroid U-74389G in preventing liver I/R injury was investigated in a swine model. Ischemia was produced by portal vein occlusion. Two sets of experiments were performed, each with two groups (n=7 per group). In the first group, the potential protective effect of an intracaval injection of U-74389G after a 30-min ischemia, followed by a 60-min reperfusion period was assessed (biopsies at 0, 15, 30 and 90 min experimental time). In the second set, the effect of intracaval U-74389G injection after 30 min of ischemia, followed by a longer reperfusion period of 120 min was determined (biopsies at 0, 15, 30 and 150 min experimental time). Liver malondialdehyde, hepatocyte vacuolation-degeneration, venous congestion, inflammatory cell infiltration, sinus congestion-dilation and Chiu score of intestinal damage were determined at up to 150 min of reperfusion. In the second set of experiments, the Chiu score of intestinal damage was improved by the administration of U-74389G (3.17±0.40 vs. 4.33±0.21; P=0.030). However, in the two sets of experiments, the liver inflammatory reaction was more pronounced in the U-74389G groups (P=0.017 for the first set, P=0.021 for the second set). No significant effect of U-74389G on any other parameters was detected. In conclusion, intestinal damage due to portal venous congestion and reflow appears to be mitigated by the lazaroid U-74389G; however, intracaval administration of U-74389G does not appear to exert any protective effects against liver I/R-induced inflammation.

Abstract
This systematic review and meta-analysis of cohort studies examine the association of meat, fish, and dairy product consumption with the risk of hematological neoplasms in adults. Thirteen studies encompassing 1,480,986 participants and 10,442 incident cases were included. Red or processed meat consumption was not associated with the risk of leukemia, acute myeloid leukemia, non-Hodgkin lymphoma (NHL) and small lymphocytic lymphoma/chronic lymphocytic leukemia (CLL/SLL). Poultry consumption did not seem to affect the risk of leukemia, NHL, CLL/SLL, and multiple myeloma (MM). Fish consumption was not associated with leukemia, NHL, CLL/SLL, and MM risk. Interestingly though, fish consumption was positively associated with myeloid leukemia risk (pooled RR = 1.74, 95% CI: 1.22-2.47, random effects, highest vs. lowest category). Milk and dairy product consumption was not associated with NHL and leukemia risk. In conclusion, methodologically strict prospective studies are mandatory, in order to extract reliable conclusions concerning the role of these dietary factors in hematological malignancies.

Abstract
Overweight/obesity, adult attained height and physical activity are possible risk factors for hematological malignancies. This meta-analysis aims to evaluate the associations between these factors and hematological cancer risk in adults. Eligible cohort studies were sought in PubMed up to May 31, 2016; overall, 44 studies were included in the present analyses. Pooled relative risk estimates were calculated using random-effects models; separate analyses were conducted for non-Hodgkin lymphoma (NHL) and subtypes (diffuse large B-cell lymphoma, DLBCL; follicular cell lymphoma; small lymphocytic lymphoma/chronic lymphocytic leukemia, SLL/CLL), Hodgkin lymphoma (HL), multiple myeloma (MM), leukemia and subtypes (acute lymphoblastic leukemia, acute myeloid leukemia, AML). Obesity was associated with increased risk of NHL, HL, MM, leukemia overall and AML in both sexes, as well as with higher DLBCL risk in women; the dose-response meta-regression analysis confirmed these associations. Less pronounced effects were observed regarding overweight, as it was associated with increased MM risk in both sexes, NHL risk in males, DLBCL and overall leukemia risk in females. Taller men presented with significantly higher risk of NHL and taller women were affected by higher risk of NHL, DLBCL, FL, CLL/SLL, MM, leukemia and AML. On the other hand, physical activity and abdominal fatness were not associated with the risk of hematological malignancies. In conclusion, this meta-analysis highlights the pivotal role of anthropometric measures in shaping the risk of hematological malignancies in adults. Additional, well-designed studies stemming from all the continents are needed for the further substantiation and generalization of the results.

Evaluation of pre-mir-34a rs72631823 single nucleotide polymorphism in triple negative breast cancer: A case-control study. Oncotarget 2018; 9:36906-36913. [PMID: 30651924 PMCID: PMC6319339 DOI: 10.18632/oncotarget.26385] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Accepted: 11/03/2018] [Indexed: 12/19/2022] Open
Abstract
Aim The purpose of this study is to evaluate the role of pre-miR34a rs72631823 as potential risk factor and/or prognostic marker in patients with triple negative breast cancer. Methods 114 samples of DNA from paraffin embedded breast normal tissues of patients with triple negative breast cancer and 124 samples of healthy controls were collected and analyzed for pre-miR34a rs72631823 polymorphism. Results Pre-miR34a rs72631823 A allele was associated with increased TNBC risk both in univariate and multivariate analysis. The number of pre-miR34a rs72631823 AA subjects was very small and the association did not reach significance (p = 0.176, Fisher’s exact test). The examined polymorphism was not associated with overall survival at the univariate or multivariate Cox regression analysis (adjusted HR = 1.60, 95%CI: 0.64–3.96 for miR34 rs72631823 GA/AA vs. GG). Conclusion Our case-control study suggests that pre-miR34a rs72631823 A allele is associated with increased triple negative breast cancer risk.

Longer procoagulant phospholipid-dependent clotting time, lower endogenous thrombin potential and higher tissue factor pathway inhibitor concentrations are associated with increased VTE occurrence in patients with newly diagnosed multiple myeloma: results of the prospective ROADMAP-MM-CAT study. Blood Cancer J 2018; 8:102. [PMID: 30405097 PMCID: PMC6221885 DOI: 10.1038/s41408-018-0135-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 06/09/2018] [Accepted: 06/15/2018] [Indexed: 01/14/2023] Open
Abstract
Venous thromboembolism (VTE) is a common complication in newly diagnosed symptomatic multiple myeloma (NDMM) patients. We explored cellular and plasma hypercoagulability in NDMM patients to identify relevant biomarkers that can be used in combination with clinical factors in the development of a risk assessment model (RAM) for VTE. Untreated patients (n = 144) with NDMM were prospectively enrolled, baseline biomarkers prior to anti-myeloma treatment and thromboprophylaxis initiation were obtained. These were compared against values in a group of healthy individuals with similar age and sex distribution. The primary study end point was symptomatic VTE occurrence. At 12-month follow-up cumulative VTE rate was 10.4%. NDMM patients showed biological signs of cellular and plasma hypercoagulability and endothelial cell activation. Procoagulant phospholipid clotting time (Procoagulant-PPL) was shorter, P-selectin levels lower and thrombin generation attenuated overall compared to healthy subjects. Longer Procoag-PPL®, lower endogenous thrombin potential (ETP), and higher levels of tissue factor pathway inhibitor (TFPI) were associated with VTE occurrence. Multivariate analysis showed that Procoag-PPL® and ETP were independent risk factors for VTE. We conclude that Procoag-PPL® and ETP can be prospectively incorporated into a RAM for VTE in MM in combination with clinical and disease risk factors.

Abstract
There has been accumulating evidence that several micronutrients may play a protective role in the risk of solid cancers. However, their role in hematological malignancies remains to be elucidated; this meta-analysis aims to evaluate the associations between micronutrient intake as well as supplementation and risk of hematological cancer in adults. Eligible cohort studies (examining intake of vitamin A, vitamin C, vitamin D, vitamin E, lycopene, folate, iron, carotenoids, beta-carotene, selenium, pyridoxine) were sought in PubMed up to July 31, 2016. Random-effects models were used for the calculation of pooled relative risks (RR) with their 95% confidence intervals (CI). Twelve cohort studies were deemed eligible. Null associations were noted regarding supplemented vitamin A (pooled relative risk [RR] = 0.92, 95% confidence interval [CI]: 0.80-1.07), supplemented vitamin C (pooled RR = 1.00, 95%CI: 0.90-1.12), total vitamin D (pooled RR = 1.05, 95%CI: 0.91-1.20), supplemented vitamin E (pooled RR = 0.98, 95%CI: 0.88-1.10), and dietary lycopene intake (pooled RR = 1.00, 95%CI: 0.86-1.16) and the risk of non-Hodgkin lymphoma. No summary estimates are provided for other hematological malignancies due to the limited number of studies. Future prospective trials should be conducted for a better understanding of this field; especially regarding Hodgkin lymphoma, leukemia and plasma cell neoplasms, on which data are scarce.

Prospective Assessment of Clinical Risk Factors and Biomarkers of Hypercoagulability for the Identification of Patients with Lung Adenocarcinoma at Risk for Cancer-Associated Thrombosis: The Observational ROADMAP-CAT Study. Oncologist 2018; 23:1372-1381. [PMID: 30104289 DOI: 10.1634/theoncologist.2017-0530] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Accepted: 03/22/2018] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND The aim of this prospective study was to identify the most clinically relevant hypercoagulability biomarkers in lung adenocarcinoma patients for elaboration of an improved risk assessment model (RAM) for venous thromboembolism (VTE). SUBJECTS, MATERIALS, AND METHODS One hundred fifty ambulatory patients with lung adenocarcinoma were prospectively enrolled. Thrombin generation, procoagulant phospholipid-dependent clotting time (Procoag-PPL), tissue factor activity (TFa), factor VIIa (FVIIa), factor V (FV), antithrombin, D-Dimers, P-selectin, and heparanase levels were assessed in platelet-poor plasma at inclusion (baseline) and at the end of the third chemotherapy cycle (third chemotherapy). Cox regression analysis was used to identify independent VTE predictors. RESULTS At baseline, patients had significantly attenuated thrombin generation, shorter Procoag-PPL, higher levels of TFa, D-Dimers, and heparanase, and lower levels of FVIIa and P-selectin, compared with controls. A significant increase in Procoag-PPL, FV, and FVIIa and a decrease of P-selectin levels were observed between baseline and third chemotherapy. Hospitalization within the last 3 months prior to assessment, time since cancer diagnosis less than 6 months, mean rate index (MRI) of thrombin generation, and Procoag-PPL were independently associated with symptomatic VTE. Accordingly, a prediction model including Procoag-PPL and MRI showed significant discriminating capacity (area under the curve: 0.84). CONCLUSION Ambulatory patients with lung adenocarcinoma may display pronounced blood hypercoagulability due to decreased Procoag-PPL, increased endothelial cell activation, and increased degradation of fibrin. Incorporation of Procoag-PPL and MRI of thrombin generation may improve the accuracy of a VTE-RAM in the above setting. IMPLICATIONS FOR PRACTICE The prospective ROADMAP-CAT study identified two biomarkers of hypercoagulability, the procoagulant phospholipid-dependent clotting time (Procoag-PPL) and the mean rate index (MRI) of the propagation phase of thrombin generation assessed with the Calibrated Automated Thrombinoscope, as being clinically relevant for the classification of ambulatory patients with lung adenocarcinoma receiving a maximum of one cycle of chemotherapy into high and intermediate/low risk for venous thromboembolism. Measurement of Procoag-PPL and MRI within 1 month after the administration of the first chemotherapy cycle provides significant accuracy of the assessment. Association of the Procoag-PPL and MRI with the clinical risk assessment model for cancer-associated thrombosis in ambulatory patients with solid tumors (COMPASS-CAT RAM) further improved its accuracy.

Abstract
Current convincing evidence suggests that alcohol intake increases the risk of several carcinomas, which might subsequently lead to a recommendation toward limiting alcohol consumption. However, there are accumulating data worth meta-analyzing that show a different effect on the risk of hematological malignancies. Eligible cohort studies were sought in PubMed database up to August 31, 2016. Separate analyses were performed by subtype of hematological malignancy (non-Hodgkin lymphoma [NHL] and subtypes, Hodgkin lymphoma [HL], leukemia and subtypes), time status (ever, current, former), level of consumption (light, moderate, heavy), alcoholic beverage (total alcohol, beer, liquor, wine) and gender. Moderate and heavy alcohol consumption were significantly associated with reduced risk of NHL (relative risk [RR] = 0.85, 95% confidence interval [CI]: 0.80-0.90 and RR = 0.73, 95%CI: 0.60-0.89, respectively); a protective trend was also shown for light alcohol intake (RR = 0.93, 95%CI: 0.87-1.00). Specifically, beer consumption was associated with reduced NHL risk (RR = 0.88, 95%CI: 0.81-0.95). However, the association regarding other alcoholic beverages seemed null. The beneficial effects of alcohol mainly pertained to Diffuse Large B-Cell Lymphoma (DLBCL) (RR = 0.83, 95%CI: 0.77-0.89) and Follicular Lymphoma (FL) (RR = 0.85, 95%CI: 0.78-0.93). There was also no association between alcohol consumption and risk of HL or leukemias. In contrast to most solid malignancies, alcohol seems to confer a protective effect on NHL risk, especially on DLBCL and FL subtypes, with beer being notably beneficial.

Abstract
BACKGROUND/AIM Studies have focused on heat shock protein (Hsp) inhibitors as potential treatment agents in breast cancer, with controversial results. Adopting a pathophysiological perspective, this systematic review aims to synthesize the evidence examining the association between Hsp70/Hsp90 expression and breast cancer prognosis, as well as prognosis-related clinicopathological indices. Secondarily, changes in Hsp70/Hsp90 expression in the continuum of breast neoplasia were assessed. MATERIALS AND METHODS Hsp70/Hsp90 expression was approached globally, quantified by means of immunohistochemistry, western blot or PCR. This study was performed in accordance with the PRISMA guidelines. Relevant studies were sought in PubMed, up to December 31, 2015. RESULTS A total of 23 eligible studies were identified (7,288 breast cancer cases). High Hsp90 expre s sion was associated with worse overall survival (pooled RR=1.48, 95%CI=1.21-1.82) and marginally with worse disease-free survival. High Hsp70 expression also correlated with worse disease-free survival (pooled RR=1.77, 95%CI=1.71-2.82). Hsp70 intense expression correlated with ER positivity (pooled OR=3.51, 95%CI=1.31-9.40) and PR positivity (pooled OR=2.48, 95%CI=1.39-4.44). No significant associations were noted between Hsp70/Hsp90 expression and clinicopathological variables including histological grade, tumor size, nodal metastasis or patient age at diagnosis. No clear pattern emerged for Hsp70/Hsp90 expression along the breast neoplasia continuum. CONCLUSION This systematic review and meta-analysis highlights the prognostic role of Hsp90 and Hsp70 expression in breast cancer. Further high-quality studies, with detailed reporting are needed to provide epidemiological evidence complementing the findings of ongoing clinical trials on Hsp inhibitors.

Abstract
Background and aims Primary malignant peritoneal mesothelioma is a rare malignancy with an unfavorable prognosis. Pemetrexed has proven effective in the treatment of malignant mesothelioma, alone or in combination with platinum agents. In the present study, chemo-naïve patients were evaluated for the efficacy and safety of the pemetrexed-cisplatin combination. Methods Six patients with diffuse peritoneal mesothelioma were treated with 6 cycles of pemetrexed (500 mg/m2) and cisplatin (75 mg/m2). Chemotherapy was administered on an outpatient basis every 3 weeks. Results Complete response was observed in 2 patients (33%) and partial response was observed in 3 patients (50%). The estimated median overall survival was 24 months and the estimated median time to disease progression was 9.5 months. The regimen was well tolerated. Conclusions Though our data reflect a small sample size, pemetrexed plus cisplatin accomplished a particularly high clinical benefit rate on chemo-naïve patients.

Abstract
OBJECTIVE To investigate an alternative combination for anaesthesia induction in swine. STUDY DESIGN Randomized, 'blinded' experimental study. ANIMALS Forty-five Landrace/Large White swine weighing 20.0±1.5 kg. METHODS Pulse oximetry, heart rate (HR) and blood pressure were measured after premedication with ketamine, midazolam and atropine as well as after intubation following induction with a fixed dose of 0.2 mg kg-1 midazolam combined with 1, 2, 3, 4 or 5 μg kg-1 remifentanil (groups R1, R2, R3, R4 and R5, respectively). Intubation was evaluated using a numerical scoring system assessing jaw relaxation, resistance to the laryngoscope, vocal cord position, vocal cord movement and response to intubation. The time required to intubate and necessity for an additional midazolam dose were recorded. Baseline and post-intubation variables were compared with paired t tests, whereas for differences between the remifentanil groups the Spearman's rank correlation coefficient was estimated. Multivariate regression analysis was performed to disentangle the effect of remifentanil dose and the additional midazolam. RESULTS Higher dose of remifentanil was associated with better vocal cord position (p<0.001), better response to intubation (p<0.001), shorter time required for intubation (p=0.030) and less frequent necessity for additional administration of midazolam (p=0.004). In total, 39.5% of the animals required additional midazolam. In groups R1, R4 and R5, there were decreases in HRs (p=0.009, p=0.008 and p=0.032, respectively) between baseline and post-intubation phase; in groups R3 and R4, there were decreases in systolic blood pressure (p=0.040 and p=0.019, respectively). In the multivariate analysis, remifentanil dose was not associated with the observed changes in haemodynamic variables. One animal developed apnoea and four electrocardiographic anomalies; all resolved without pharmaceutical interventions. CONCLUSIONS AND CLINICAL RELEVANCE A combination of 0.2 mg kg-1 midazolam with 4 or 5 μg kg-1 remifentanil may provide an alternative method of anaesthesia induction for swine.

Abstract
Purpose The purpose of this study was to evaluate the role of inflammatory/lipid markers and potential risk factors for diabetic retinopathy (DR) development in newly diagnosed patients with type 2 diabetes mellitus (T2DM). Methods Participants in this study were 1062 patients with newly diagnosed T2DM. Demographic and clinical data of patients were collected. Assessment of DR status was performed using digital two-field photography. In addition, HbA1c (%), lipid profile, and urinary albumin were measured at recruitment. The following inflammatory markers were also measured: serum C-reactive protein, white blood cells, platelet, adiponectin, IL-4, IL-6, IL-10, vascular endothelial growth factor, tumor necrosis factor-α (TNF-α), IL-1b, IL-1 receptor antagonist (IL-1RA), and monocyte chemotactic protein-1. Univariate and multivariate analyses of the association of various potential risk factors and DR were conducted. Results Univariate analysis showed that male sex, any cardiovascular event, and HbA1c were positively associated with DR, while IL-1RA, IL-1b, IL-6, and TNF-α were significantly negatively associated with presence of DR in the cohort. Risk factors that remained significantly associated with DR presence at the multivariate analysis were male sex, any cardiovascular event, HbA1c, and IL-1RA. Conclusions Our study demonstrated that HbA1c levels, male sex, and previous cardiovascular events were risk factors for presence of DR in people with newly diagnosed T2DM, while IL-1RA seemed to have a protective role. The prevalence of DR in our population was 20.2%, reflecting current practice. Our findings may contribute to future risk-based modelling of screening for DR.

Abstract
The diagnosis and treatment of squamous cell carcinoma of the pancreas pose dilemmas in the clinical practice. The present study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Eligible articles were sought in MEDLINE up to 30th April 2016. A pooled Cox regression analysis was performed to evaluate factors potentially associated with overall survival (OS) and relapse-free survival (RFS). Fifty-four cases of pure squamous cell pancreatic carcinomas were identified in total. The mean age was 61.9 years, and most patients were males (61.1%). The median OS was 7 months. Resectability (p = 0.003) and more recent publication year (p < 0.001) were associated with better OS, as was low/intermediate tumour grade (p = 0.032) with RFS. Despite its poor prognosis, survival rates of pancreatic squamous cell carcinoma seem improved during the recent years; resectability and low/intermediate grade emerged as favourable prognostic factors. Collaborative epidemiological studies are deemed necessary to further validate the results stemming from the published case reports of this rare entity.

Abstract
OBJECTIVE We examined the predictive ability of anti-Müllerian hormone (AMH) for clinical pregnancy in women who underwent in vitro fertilization (IVF) cycles in a short agonist protocol. DESIGN This is a retrospective cohort study of 222 women undergoing their first IVF attempt between June 2010 and March 2016. Multivariate logistic regression analysis was performed to evaluate the independent associations between clinical pregnancy and its possible predictors. RESULTS 14.9% of cycles were cancelled, >3 oocytes were retrieved in 55.4% of cycles and embryo transfer was performed in 70.7% of cases. Live birth was the final outcome in 19.8% of subjects, miscarriage occurred in 4.1%, whereas no pregnancy occurred in the remaining 76.1% of the study sample. The number of oocytes, number of embryos, embryo transfer rate and pregnancy rates were positively associated with serum AMH concentrations (p <0.001, for each association). When analyzed by age quartiles, the overall association between AMH and clinical pregnancy rates was evident across all age strata. CONCLUSIONS Serum AMH levels are a strong predictive marker of clinical pregnancy in women undergoing a short agonist IVF protocol. There is also a strong association with cancellation rate, number of oocytes retrieved, poor response (≤3 oocytes), number of embryos, embryo transfer rate and live birth rates.

Abstract
BACKGROUND Medical treatment for subfertility principally involves the use of ovary-stimulating agents, including selective oestrogen receptor modulators (SERMs), such as clomiphene citrate, gonadotropins, gonadotropin-releasing hormone (GnRH) agonists and antagonists, as well as human chorionic gonadotropin. Ovary-stimulating drugs may act directly or indirectly upon the endometrium (lining of the womb). Nulliparity and some causes of subfertility are recognized as risk factors for endometrial cancer. OBJECTIVES To evaluate the association between the use of ovary-stimulating drugs for the treatment of subfertility and the risk of endometrial cancer. SEARCH METHODS A search was performed in CENTRAL, MEDLINE (Ovid) and Embase (Ovid) databases up to July 2016, using a predefined search algorithm. A search in OpenGrey, ProQuest, ClinicalTrials.gov, ZETOC and reports of major conferences was also performed. We did not impose language and publication status restrictions. SELECTION CRITERIA Cohort and case-control studies reporting on the association between endometrial cancer and exposure to ovary-stimulating drugs for subfertility in adult women were deemed eligible. DATA COLLECTION AND ANALYSIS Study characteristics and findings were extracted by review authors independently working in pairs. Inconsistency between studies was quantified by estimating I2. Random-effects (RE) models were used to calculate pooled effect estimates. Separate analyses were performed, comparing treated subfertile women versus general population and/or unexposed subfertile women, to address the superimposition of subfertility as an independent risk factor for endometrial cancer. MAIN RESULTS Nineteen studies were eligible for inclusion (1,937,880 participants). Overall, the quality of evidence was very low, due to serious risk of bias and indirectness (non-randomised studies (NRS), which was reflected on the GRADE assessment.Six eligible studies, including subfertile women, without a general population control group, found that exposure to any ovary-stimulating drug was not associated with an increased risk of endometrial cancer (RR 0.96, 95% CI 0.67 to 1.37; 156,774 participants; very low quality evidence). Fifteen eligible studies, using a general population as the control group, found an increased risk after exposure to any ovary-stimulating drug (RR 1.75, 95% CI 1.18 to 2.61; 1,762,829 participants; very low quality evidence).Five eligible studies, confined to subfertile women (92,849 participants), reported on exposure to clomiphene citrate; the pooled studies indicated a positive association ( RR 1.32; 95% CI 1.01 to 1.71; 88,618 participants; very low quality evidence), although only at high dosage (RR 1.69, 95% CI 1.07 to 2.68; two studies; 12,073 participants) and at a high number of cycles (RR 1.69, 95% CI 1.16 to 2.47; three studies; 13,757 participants). Four studies found an increased risk of endometrial cancer in subfertile women who required clomiphene citrate compared to a general population control group (RR 1.87, 95% CI 1.00 to 3.48; four studies, 19,614 participants; very low quality evidence). These data do not tell us whether the association is due to the underlying conditions requiring clomiphene or the treatment itself.Using unexposed subfertile women as controls, exposure to gonadotropins was associated with an increased risk of endometrial cancer (RR 1.55, 95% CI 1.03 to 2.34; four studies; 17,769 participants; very low quality evidence). The respective analysis of two studies (1595 participants) versus the general population found no difference in risk (RR 2.12, 95% CI 0.79 to 5.64: very low quality evidence).Exposure to a combination of clomiphene citrate and gonadotropins, compared to unexposed subfertile women, produced no difference in risk of endometrial cancer (RR 1.18, 95% CI 0.57 to 2.44; two studies; 6345 participants; very low quality evidence). However, when compared to the general population, an increased risk was found , suggesting that the key factor might be subfertility, rather than treatment (RR 2.99, 95% CI 1.53 to 5.86; three studies; 7789 participants; very low quality evidence). AUTHORS' CONCLUSIONS The synthesis of the currently available evidence does not allow us to draw robust conclusions, due to the very low quality of evidence. It seems that exposure to clomiphene citrate as an ovary-stimulating drug in subfertile women is associated with increased risk of endometrial cancer, especially at doses greater than 2000 mg and high (more than 7) number of cycles. This may largely be due to underlying risk factors in women who need treatment with clomiphene citrate, such as polycystic ovary syndrome, rather than exposure to the drug itself. The evidence regarding exposure to gonadotropins was inconclusive.

Prognostic impact of margin status in liver resections for colorectal metastases after bevacizumab. Br J Surg 2017; 104:926-935. [PMID: 28266705 DOI: 10.1002/bjs.10510] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2016] [Revised: 01/13/2017] [Accepted: 01/16/2017] [Indexed: 01/09/2023]
Abstract
BACKGROUND Margin status with resection of colorectal liver metastasis (CRLM) was an important prognostic factor in the years before the introduction of biological chemotherapy. This study examined outcomes following CRLM resection in patients who received neoadjuvant chemotherapy with or without the monoclonal antiangiogenic antibody bevacizumab. METHODS Patients who underwent surgery for CRLM at the Johns Hopkins Hospital between 2000 and 2015 were identified from an institutional database. Data regarding surgical margin status, preoperative bevacizumab administration and overall survival (OS) were assessed using multivariable analyses. RESULTS Of 630 patients who underwent CRLM resection, 417 (66·2 per cent) received neoadjuvant chemotherapy with (214, 34·0 per cent) or without (203, 32·2 per cent) bevacizumab. The remaining 213 (33·8 per cent) did not receive neoadjuvant chemotherapy. Univariable analysis found that positive margins were associated with worse 5-year OS than R0 resection (36·2 versus 54·9 per cent; P = 0·005). After dichotomizing by the receipt of preoperative bevacizumab versus chemotherapy alone, the prognostic value of pathological margin persisted among patients who did not receive preoperative bevacizumab (5-year OS 53·0 versus 37 per cent after R0 versus R1 resection; P = 0·010). OS was not significantly associated with margin status in bevacizumab-treated patients (5-year OS 46·8 versus 33 per cent after R0 versus R1 resection; P = 0·081), in whom 5-year survival was slightly worse (presumably reflecting more advanced disease) than among patients treated with cytotoxic agents alone. Pathological margin status was not significantly associated with 5-year OS in patients with a complete or near-complete response to chemotherapy and bevacizumab (43 versus 30 per cent after R0 versus R1 resection; P = 0·917), but this may be due to a type II error. CONCLUSION The impact of margin status varied according to the receipt of bevacizumab. Bevacizumab may have a role to play in improving outcomes among patients with more advanced disease.

Abstract
Introduction The purpose of our study was to investigate the impact of ketorolac addition to the well-established combination of antibiotic-steroid agent in terms of vision-related quality of life. Methods Patients were randomized to: (1) fixed combination of tobramycin 0.3%–dexamethasone 0.1%, one drop qid (n = 68) and (2) fixed combination of tobramycin 0.3%–dexamethasone 0.1%, one drop qid, plus ketorolac tromethamine 0.5%, one drop tid (n = 70). All patients completed the VFQ-25 questionnaire to assess their functional vision before cataract surgery and postoperatively on days 7, 28 and 42. The statistical analysis comprised the point-wise comparison between the two groups at the four time points for all sub-scales of the VFQ-25 questionnaire, as well as the composite score. Results No significant differences were noted regarding the composite score, as well as all subscales in all examined time points. Conclusions The addition of ketorolac did not seem to offer any additional benefit in terms of vision-related quality of life.

Serum inhibin and leptin: Risk factors for pre-eclampsia? Clin Chim Acta 2016; 463:84-87. [PMID: 27737735 DOI: 10.1016/j.cca.2016.10.013] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2016] [Revised: 10/09/2016] [Accepted: 10/09/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Pre-eclampsia and eclampsia are parts of the broader spectrum of hypertensive disorders complicating pregnancy. This study aims to examine the association between serum inhibin and leptin levels and pre-eclampsia. METHODS This study included 98 consecutive cases of pregnant women with pre-eclampsia, together with their 98 pregnant controls, matched for age, gestational week and time period of delivery. Maternal venous blood samples were obtained within 24h before delivery. In addition to serum inhibin and leptin, birth order, multiple pregnancy, maternal age, maternal overweight/obesity, maternal education, maternal smoking and family history of diabetes/hypertension, were examined as risk factors. Multivariate logistic regression analysis was performed. RESULTS At the univariate analysis, serum inhibin and leptin levels were significantly higher in cases vs. CONTROLS Pre-eclampsia occurred more frequently in primiparous women, whereas overweight and obesity were also associated with pre-eclampsia. At the multivariate analysis, higher serum inhibin levels were associated with pre-eclampsia (multivariate OR=1.09, 95%CI: 1.03-1.17, p=0.004, increase per 0.1ng/mL). On the other hand, leptin was not independently associated with the occurrence of pre-eclampsia (multivariate OR=1.02, 95%CI: 0.95-1.09, p=0.631, increase per 10ng/mL). CONCLUSIONS Elevated serum inhibin levels seem to be associated with pre-eclampsia, reflecting placental dysfunction. Increased serum leptin levels may merely reflect an elevated maternal body mass index, which is a well-known risk factor for pre-eclampsia.

Abstract
Dementia is a major global health challenge, as its burden on society will increase with population aging. Given the lack of effective pharmaceutical treatment for common types of dementia including Alzheimer's disease and vascular dementia, research interest in lifestyle modifications that could prevent, postpone the clinical syndrome or decelerate progression of dementia is growing. Among the various dietary patterns that were tested for their effects on cognition, the traditional Mediterranean diet (MeDi) has shown promising results. This review aims to summarize the epidemiological evidence on the effects of MeDi on the prevention of dementia, presenting data from cross-sectional as well as longitudinal observational studies conducted both in Mediterranean and non-Mediterranean countries. These findings have been also reproduced in the context of one recent randomized-controlled clinical trial. Postulated mechanisms of action that may account for the potential protective effect of MeDi on cognitive impairment will be briefly discussed. Despite the fact that the link between MeDi and cognitive decline has been only explored for less than a decade, data on efficacy is rapidly increasing and allows optimism that MeDi could emerge as an alternative prophylactic treatment for dementia.

Abstract
Background. Postoperative adhesions are the result of aberrant peritoneal healing. As they are the leading cause of postoperative bowel obstruction, anti-adherence barriers are advocated for their prevention. This study looks into the effect of these biomaterials on the healing of intestinal anastomoses. Materials and Methods. Thirty-three New Zealand White rabbits underwent laparotomy, transection of the terminal ileum, and creation of an end-to-end anastomosis. Animals were randomized into 3 groups: the Control group (n = 11); the Icodextrin group, receiving icodextrin 4% intraperitonealy (n = 11); and the HA/CMC group, having the anastomosis wrapped with a hyaluronic acid/carboxymethylcellulose film (n = 11). All animals were sacrificed on the seventh postoperative day. Macroscopic adhesions were graded and anastomotic strength was tested by the burst pressure. Histological healing was assessed in a semiquantitative way for the presence of ulceration, reepithelization, granulation tissue, inflammation, eosinophilic infiltration, serosal inflammation, and microscopic adhesions. Univariate and multivariate analysis was used. Results are given as medians with interquartile range. Results. The median adhesion scores were the following: Control 1 (0-3), Icodextrin 0 (0-1), HA/CMC 0 (0-0), P = .017. The burst pressure did not differ between the groups; however, all except one bowel segments tested burst away from the anastomosis. The macroscopic and histological anastomotic healing was comparable in all 3 groups. A poor histological anastomotic healing score was associated with a higher adhesion grade (odds ratio = 1.92; 95% confidence interval = 1.06-3.47; P = .032). Conclusion. Adhesion formation was inhibited by the materials tested without direct detrimental effects on anastomotic healing. Poor anastomotic healing provokes adhesions even in the presence of anti-adhesion barriers.

Abstract
BACKGROUND/AIM Endometrial cytology is an alternative perspective for the diagnosis of endometrial cancer. The present study examined the potential risk factors for strenuousness in endometrial cytology sampling. PATIENTS AND METHODS One hundred and eighty-one women who underwent endometrial cytological sampling with the Endogyn curette participated in the study. Strenuousness in obtaining the sample was graded into a five-level scale-score. Various parameters were assessed in association with the strenuousness score. Multivariate ordinal logistic regression analysis was performed. RESULTS Postmenopausal status (adjusted OR=2.63, 95%CI=1.52-4.56, p=0.001) and previous invasive/surgical procedures in the cervix (adjusted OR=2.15, 95%CI=1.10-4.24, p=0.026) were associated with higher strenuousness score. Participants' age at sampling, phase of menstrual cycle, endometrial thickness, obesity, current hormonal use and reproductive history of women were not significantly associated with the strenuousness of the procedure. CONCLUSION Increased difficulty during endometrial sampling is noted in postmenopausal women, and in patients with previous surgical procedures in the cervix.

Abstract
BACKGROUND Overweight of children and adolescents continues to be an important and alarming global public health problem. As the adolescent's time spent online has increased, problematic internet use (PIU) potentially leads to negative health consequences. This study aimed to examine the relation between PIU and overweight/obesity among adolescents in seven European countries and assess the effect of demographic and lifestyle factors recorded in the European Network for Adolescent Addictive Behaviour (EU NET ADB) survey (www.eunetadb.eu). METHODS A cross-sectional school-based survey of 14- to 17-year-old adolescents was conducted in seven European countries: Germany, Greece, Iceland, the Netherlands, Poland, Romania and Spain. Anonymous self-completed questionnaires included sociodemographic data, internet usage characteristics, school achievement, parental control and the Internet Addiction Test. Associations between overweight/obesity and potential risk factors were investigated by logistic regression analysis, allowing for the complex sample design. RESULTS The study sample consisted of 10 287 adolescents aged 14-17 years. 12.4% were overweight/obese, and 14.1% presented with dysfunctional internet behavior. Greece had the highest percentage of overweight/obese adolescents (19.8%) and the Netherlands the lowest (6.8%). Male sex [odds ratio (OR) = 2.89, 95%CI: 2.46-3.38], heavier use of social networking sites (OR = 1.26, 95%CI: 1.09-1.46) and residence in Greece (OR = 2.32, 95%CI: 1.79-2.99) or Germany (OR = 1.48, 95%CI: 1.12-1.96) were independently associated with higher risk of overweight/obesity. A greater number of siblings (OR = 0.79, 95%CI: 0.64-0.97), higher school grades (OR = 0.74, 95%CI: 0.63-0.88), higher parental education (OR = 0.89, 95%CI: 0.82-0.97) and residence in the Netherlands (OR = 0.49, 95%CI: 0.31-0.77) independently predicted lower risk of overweight/obesity. CONCLUSIONS The results indicate an association of overweight/obesity with PIU and suggest the importance of formulating preventive public health policies that target physical health, education and sedentary online lifestyle early in adolescence with special attention to boys.

Transcranial Doppler versus transthoracic echocardiography for the detection of patent foramen ovale in patients with cryptogenic cerebral ischemia: A systematic review and diagnostic test accuracy meta-analysis. Ann Neurol 2016; 79:625-35.

Abstract
OBJECTIVE Patent foramen ovale (PFO) can be detected in up to 43% of patients with cryptogenic cerebral ischemia undergoing investigation with transesophageal echocardiography (TEE). The diagnostic value of transthoracic echocardiography (TTE) in the detection of PFO in patients with cryptogenic ischemic stroke or transient ischemic attack has not been compared with that of transcranial Doppler (TCD) using a comprehensive meta-analytical approach. METHODS We performed a systematic literature review to identify all prospective observational studies of patients with cryptogenic cerebral ischemia that provided both sensitivity and specificity measures of TTE, TCD, or both compared to the gold standard of TEE. RESULTS Our literature search identified 35 eligible studies including 3,067 patients. The pooled sensitivity and specificity for TCD was 96.1% (95% confidence interval [CI] = 93.0-97.8%) and 92.4% (95% CI = 85.5-96.1%), whereas the respective measures for TTE were 45.1% (95% CI = 30.8-60.3%) and 99.6% (95% CI = 96.5-99.9%). TTE was superior in terms of higher positive likelihood ratio values (LR+ = 106.61, 95% CI = 15.09-753.30 for TTE vs LR+ = 12.62, 95% CI = 6.52-24.43 for TCD; p = 0.043), whereas TCD demonstrated lower negative likelihood values (LR- = 0.04, 95% CI = 0.02-0.08) compared to TTE (LR- = 0.55, 95% CI = 0.42-0.72; p < 0.001). Finally, the area under the summary receiver operating curve (AUC) was significantly greater (p < 0.001) in TCD (AUC = 0.98, 95% CI = 0.97-0.99) compared to TTE studies (AUC = 0.86, 95% CI = 0.82-0.89). INTERPRETATION TCD is more sensitive but less specific compared to TTE for the detection of PFO in patients with cryptogenic cerebral ischemia. The overall diagnostic yield of TCD appears to outweigh that of TTE.

Abstract
PURPOSE The purpose of this study was to evaluate the regression of neovascularization elsewhere (NVE) after panretinal photocoagulation (PRP) based on its location in relation to the internal limiting membrane (ILM). METHODS Participants in this retrospective case series were 47 patients with active NVE within the vascular arcade. All patients were treated with PRP and followed up for at least 12 months. The time to regression of NVE based on its location relative to the ILM on spectral domain-optical coherence tomography (SD-OCT) was analyzed. RESULTS The proportion of eyes, showing regression of NVE at the end of follow-up period was 19/25 (76 %) in the "below ILM" group and 13/22 (59 %) in the "above ILM" group. The "below ILM" group was associated with a twofold enhanced regression of NVE in comparison to the "above ILM" group (HR = 2.13, p = 0.038). CONCLUSIONS Regression of NVE is determined by its location relative to the ILM. Patients with "below ILM" NVE were found to show a twofold increased regression rate in comparison with the "above ILM" group, while the proportion of eyes showing regression of NVE at the end of the follow-up period was significantly greater in the "below ILM" than the "above ILM" group.

Abstract
From the available literature, it is unclear what proportion of pancreatic adenocarcinomas express estrogen receptors (ERα, ERβ), progesterone receptors (PR), and androgen receptors (AR), and if any of these markers have prognostic significance. We aimed to assess (1) the expression and (2) the correlation of the aforementioned markers with clinicopathological parameters and prognosis in patients with pancreatic adenocarcinoma. During a five-year period, 60 patients with pancreatic ductal adenocarcinoma underwent surgical resection at a single institution. Immunohistochemical stains of the studied markers were quantified by Image analysis system. ERα expression was positively associated with PR expression. Moreover, ERβ was inversely associated with the presence of metastases, whereas no significant associations implicated AR. As far as the prognostic significance of the studied receptors is concerned, higher ERα expression correlated with poorer survival at the univariate analysis, but the finding dissipated at the multivariate approach. No significant associations with overall survival were noted regarding the other receptors. The role of sex hormone receptors in the survival from pancreatic adenocarcinoma seems rather limited. Further prospective studies assessing those receptors should ideally be designed in order to confirm our results and possibly outline additional correlations between other steroid receptors and features of pancreatic adenocarcinoma.

Abstract
Objective This meta-analysis aims to examine the association between being overweight/obese and risk of meningiomas and gliomas as well as overall brain/central nervous system (CNS) tumors. Study Design Potentially eligible publications were sought in PubMed up to June 30, 2014. Random-effects meta-analysis and dose-response meta-regression analysis was conducted. Cochran Q statistic, I-squared and tau-squared were used for the assessment of between-study heterogeneity. The analysis was performed using Stata/SE version 13 statistical software. Results A total of 22 studies were eligible, namely 14 cohort studies (10,219 incident brain/CNS tumor cases, 1,319 meningioma and 2,418 glioma cases in a total cohort size of 10,143,803 subjects) and eight case-control studies (1,009 brain/CNS cases, 1,977 meningioma cases, 1,265 glioma cases and 8,316 controls). In females, overweight status/obesity was associated with increased risk for overall brain/CNS tumors (pooled RR = 1.12, 95%CI: 1.03–1.21, 10 study arms), meningiomas (pooled RR = 1.27, 95%CI: 1.13–1.43, 16 study arms) and gliomas (pooled RR = 1.17, 95%CI: 1.03–1.32, six arms). Obese (BMI>30 kg/m2) females seemed particularly aggravated in terms of brain/CNS tumor (pooled RR = 1.19, 95%CI: 1.05–1.36, six study arms) and meningioma risk (pooled RR = 1.48, 95%CI: 1.28–1.71, seven arms). In males, overweight/obesity status correlated with increased meningioma risk (pooled RR = 1.58, 95%CI: 1.22–2.04, nine study arms), whereas the respective association with overall brain/CNS tumor or glioma risk was not statistically significant. Dose-response meta-regression analysis further validated the findings. Conclusion Our findings highlight obesity as a risk factor for overall brain/CNS tumors, meningiomas and gliomas among females, as well as for meningiomas among males.
