Abstract
INTRODUCTION Currently 11 infectious agents are classified as carcinogenic but the role of infectious agents on outcomes of epithelial ovarian cancer is largely unknown. OBJECTIVE To explore the association between infectious agents and ovarian cancer, we investigated the prevalence of viral DNA in primary ovarian cancer tumors and its association with clinical outcomes. METHODS Archived tumors from 98 patients diagnosed with high-grade serous epithelial ovarian cancer were collected between 1/1/1994 and 12/31/2010. After DNA extraction, Luminex technology was utilized to identify polymerase chain reaction-amplified viral DNA for 113 specific viruses. Demographic data and disease characteristics were summarized using descriptive statistics. We used logistic regression and Cox proportional hazards model to assess associations between tumor viral status and disease outcome and between tumor viral presence and overall survival (OS), respectively. RESULTS Forty-six cases (45.9%) contained at least one virus. Six highly prevalent viruses were associated with clinical outcomes and considered viruses of interest (VOI; Epstein-Barr virus 1, Merkel cell polyomavirus, human herpes virus 6b, and human papillomaviruses 4, 16, and 23). Factors independently associated with OS were presence of VOI (HR 4.11, P = 0.0001) and platinum sensitivity (HR 0.21, P<0.0001). Median OS was significantly decreased when tumors showed VOI versus not having these viruses (22 vs 44 months, P<0.0001). Women <70 year old with VOI in tumors had significantly lower median OS versus age-matched women without VOI (20 vs 57 months, P = 0.0006); however, among women ≥70 years old, there was no difference in OS by tumor virus status. CONCLUSIONS The presence of a VOI was significantly associated with a lower OS. These findings may have implications for clinical management of ovarian cancer but require additional studies.

Abstract
Objective This study aims to evaluate the feasibility and safety of planned postoperative day 1 discharge (PPOD1) among patients who undergo laparotomy (XL) in the department of gynecology oncology utilizing a modified enhanced recovery after surgery (ERAS) protocol including opioid-sparing anesthesia (OSA) and defined discharge criteria. Methods Patients undergoing XL and minimally invasive surgery (MIS) were enrolled in this prospective, observational cohort study after the departmental implementation of a modified ERAS protocol. The primary outcome was quality of life (QoL) using SF36, PROMIS GI, and ICIQ-FLUTS at baseline and 2- and 6-week postoperative visits. Statistical significance was assessed using the two-tailed Student's t-test and non-parametric Mann-Whitney two-sample test. Results Of the 141 subjects, no significant demographic differences were observed between the XL group and the MIS group. The majority of subjects, 84.7% (61), in the XL group had gynecologic malignancy [vs. MIS group; 21 (29.2%), p < 0.001]. All patients tolerated OSA. The XL group required higher intraoperative opioids [7.1 ± 9.2 morphine milligram equivalents (MME) vs. 3.9 ± 6.9 MME, p = 0.02] and longer surgical time (114.2 ± 41 min vs. 96.8 ± 32.1 min, p = 0.006). No significant difference was noted in the opioid requirements at the immediate postoperative phase and the rest of the postoperative day (POD) 0 or POD 1. In the XL group, 69 patients (73.6%) were successfully discharged home on POD1. There was no increase in the PROMIS score at 2 and 6 weeks compared to the preoperative phase. The readmission rates within 30 days after surgery (XL 4.2% vs. MIS 1.4%, p = 0.62), rates of surgical site infection (XL 0% vs. MIS 2.8%, p = 0.24), and mean number of post-discharge phone calls (0 vs. 0, p = 0.41) were comparable between the two groups. Although QoL scores were significantly lower than baseline in four of the nine QoL domains at 2 weeks post-laparotomy, all except physical health recovered by the 6-week time point. Conclusions PPOD1 is a safe and feasible strategy for XL performed in the gynecologic oncology department. PPOD1 did not increase opioid requirements, readmission rates compared to MIS, and patient-reported constipation and nausea/vomiting compared to the preoperative phase.

Abstract
The intrauterine device is one of the most effective forms of contraception. Use of the intrauterine device has increased in the United States over the last 2 decades. Two formulations are commercially available in the United States: the levonorgestrel-releasing intrauterine device and the copper intrauterine device. The levonorgestrel intrauterine device releases progestin, causing endometrial suppression and cervical mucus thickening, whereas the primary mechanism of action of the copper intrauterine device is to create a local inflammatory response to prevent fertilization. Whereas the protective effects of combined hormonal contraception against ovarian and endometrial cancer, and of tubal sterilization against ovarian cancer are generally accepted, less is known about the effects of modern intrauterine devices on the development of gynecologic malignancies. The best evidence for a protective effect of intrauterine device use against cancer incidence pertains to levonorgestrel intrauterine devices and endometrial cancer, although studies suggest that both copper intrauterine devices and levonorgestrel intrauterine devices reduce endometrial cancer risk. This is supported by the proposed dual mechanisms of action including both endometrial suppression and a local inflammatory response. Studies on the relationship between intrauterine device use and ovarian cancer risk show conflicting results, although most data suggest reduced risk of ovarian cancer in intrauterine device users. The proposed biological mechanisms of ovarian cancer reduction (foreign-body inflammatory response, increased pH, antiestrogenic effect, ovulation suppression) vary by type of intrauterine device. Whereas it has been well established that use of copper intrauterine devices confers a lower risk of cervical intraepithelial neoplasms, the effect of levonorgestrel intrauterine device use on cervical cancer remains unclear. Older studies have linked its use to a higher incidence of cervical dysplasia, but more recent literature has found a decrease in cervical cancer with intrauterine device use. Various mechanisms of protection are postulated, including device-related inflammatory response in the endocervical canal and prostaglandin-mediated immunosurveillance. Overall, the available evidence suggests that both levonorgestrel intrauterine devices and copper intrauterine devices reduce gynecologic cancer risk. Whereas there is support for the reduction of endometrial cancer risk with hormonal and copper intrauterine device use, and reduction of cervical cancer risk with copper intrauterine device use, evidence in support of risk reduction with levonorgestrel intrauterine device use for cervical and ovarian cancers is less consistent.

Abstract
OBJECTIVE The Lifestyle Intervention for oVarian cancer Enhanced Survival (LIVES) is a national study of a combined diet and physical activity intervention for stage II-IV ovarian cancer survival, an under-represented cancer in lifestyle behavioral intervention research. Here, we present the data on recruitment, retention, and baseline demographic, clinical and lifestyle behavior characteristics of the LIVES study participants. METHODS The LIVES study (NRG Oncology/GOG 0225) is a Phase III diet plus physical activity intervention trial testing the hypothesis that ovarian cancer survivors in the lifestyle intervention will demonstrate better progression-free survival than those in the control condition. Study interventions were delivered via centralized telephone-based health coaching. Baseline descriptive statistics were computed for demographic, clinical, and lifestyle behavior characteristics. RESULTS The LIVES study exceeded its recruitment goals, enrolling 1205 ovarian cancer survivors from 195 NRG/NCORP-affiliated oncology practices across 49 states from 2012 to 2018. The mean age of enrollees was 59.6 years; the majority (69.4%) with stage III disease; 89% White, 5.5% Hispanic; 64% overweight/obese. Baseline self-reported diet showed a mean daily intake of 6.6 servings of fruit and vegetables, 62.7 fat grams, and 21.7 g of fiber. Physical activity averaged 13.0 MET-hours/week of moderate to vigorous physical activity; 50.9 h/week of sedentary time. Retention rates exceeded 88%. CONCLUSION The LIVES study demonstrates efficiency in recruiting and retaining ovarian cancer survivors in a 24-month study of diet and physical activity intervention with a primary endpoint of progression free survival that will be reported.

Abstract
Purpose The objective of this study was to assess the efficacy and safety of pembrolizumab in combination with standard carboplatin/paclitaxel in patients with advanced endometrial cancer (EC). Patients and Methods This single-arm, open-label, multi-center phase II study enrolled patients with RECIST measurable advanced EC. Patients could have received < 1 prior platinum-based regimen and < one non-platinum chemotherapy. The primary endpoint was objective response rate (ORR). Planned sample size of 46 subjects provided 80% power to detect 15% ORR improvement compared to historical control rate of 50%. Results 46 patients were enrolled, and 43 were evaluable for ORR. Median age was 66 (range: 43-86). Thirty-four (73.9%) patients had recurrent and 12 (26.1%) primary metastatic EC. Patients received carboplatin AUC 6, paclitaxel 175mg/m2 and pembrolizumab 200mg IV every 3 weeks for up to 6 cycles. ORR was 74.4% (32/43), higher than historic controls (p = 0.001). Median PFS was 10.6 months (95% CI 8.3-13.9 months). The most common grade 1-2 treatment related adverse event (TRAEs) included anemia (56.5%), alopecia (47.8%), fatigue (47.8%) and neuropathy (13%), while the most common grade 3-4 TRAEs were lymphopenia, leukopenia, and anemia (19.6% each). High-dimensional spectral flow cytometry (CyTEK) identified enrichment in peripheral CD8+ and CD4+ T cell populations at baseline in responders. The CD8+ T cell compartment in responders exhibited greater expression levels of PD-1 and PD-L1 and higher abundance of effector memory CD8+ cells compared to non-responders. Conclusions Addition of pembrolizumab to carboplatin and paclitaxel for advanced EC was tolerated and improved ORR compared to historical outcomes.

Abstract
OBJECTIVES Older women have a worse prognosis with advanced epithelial ovarian cancer (EOC) and comorbidities likely contribute to poor outcomes. We sought to identify comorbid conditions and treatment-related factors in older women. METHODS A retrospective chart review identified 351 patients who underwent cytoreductive surgery (CRS). 100/351 (28.5%) were ≥ 70 years old. Demographic and clinicopathologic information was collected. Crude progression-free (PFS) and overall survival (OS) estimates were calculated using Kaplan-Meier method. Cox proportional hazards regression model was used to estimate hazard ratios and adjustments for confounders. RESULTS Study subjects ≥70 years old had significantly: higher Cumulative Illness Rating Scale-Geriatric (CIRS-G) score (5.9 vs 4.3; p = 0.0001), less completion of adjuvant chemotherapy (24% vs 15.1%; p = 0.049), less intraperitoneal (IP) therapy (18.2% vs 35.5%; p = 0.002), less clinical trial participation (16% vs 26.3%; p = 0.040), decreased platinum sensitivity (60% vs 73.7%; p = 0.012) and lacked BRCA mutations (0% vs 12%; p = 0.0006). They were less likely to have optimal CRS (75% vs 86.9%; p = 0.007) with same surgical complexity (p = 0.89). Patients ≥70 had significantly worse PFS and OS. In a multivariate analysis, better OS was associated with younger age (<70 years old), any IP therapy, completion of adjuvant chemotherapy, and platinum sensitivity. CONCLUSION The older cohort had worse CIRS-G scores (5.9 vs 4.3; p = 0.0001), but no strong associations between comorbidities and treatment characteristics, but less optimal CRS rates (75% vs 86.9%; p = 0.007) with similar surgical complexity and less platinum sensitivity. Our results show comorbid conditions in older patients with advanced EOC may have less impact than tumor biology.

Abstract
Background: Many women see an obstetrician/gynecologist (OB/GYN) annually and receive their primary care from an OB/GYN. Understanding OB/GYNs' human papillomavirus (HPV) vaccination practices, including knowledge of and barriers to vaccination, is essential to design effective interventions to increase vaccination. This study evaluated OB/GYN knowledge, attitudes, and beliefs regarding vaccinating both younger (18-26 years) and mid-adult (27-45 years) women. Materials and Methods: Data were collected from OB/GYN providers in October 2019 through a nationwide web-based survey. Items included the following: HPV-related vaccination practices, recommendation strength, knowledge (seven items), benefits (four items), and barriers (eight items). Results: The sample (n = 224) was majority were White (69%), men (56%), and practice in suburban clinics (55%). Most (84%) reported they usually or always recommend HPV vaccine to eligible patients, but estimated only about half (51%) of other OB/GYNs did the same. Recommendation strength varied by patient age with 84% strongly recommending it to patients ≤18 years, compared with 79% and 25% strongly recommending to younger and mid-adult patients, respectively (p < 0.01). Participants reported lower benefits (p = 0.007) and higher barriers (p < 0.001) for 27- to 45-year-old patients compared with younger patients. Cost was the most frequently reported barrier, regardless of patient age. Overall knowledge was high (m = 5.2/7) but 33% of participants did not know the vaccine was safe while breastfeeding. Conclusions: Although providers reported strongly and consistently recommending the HPV vaccination to their adult patients, there were gaps in knowledge and attitudinal barriers that need to be addressed. Provider performance feedback may be important in improving HPV vaccination awareness among providers.

Abstract
INTRODUCTION In 2018, the U.S. Food and Drug Administration extended the licensure for human papillomavirus vaccination to include everyone aged 27-45 years. In 2019, the Advisory Committee on Immunization Practices issued a recommendation that adults aged 27-45 years and their providers engage in shared clinical decision making about human papillomavirus vaccination. In addition, in 2019, the Advisory Committee on Immunization Practices reiterated that all previously unvaccinated individuals receive catch-up vaccination through age 26 years. This study estimates the pre-recommendation prevalence of human papillomavirus vaccination and factors associated with vaccination in 2 age groups (19-26 years [young adults] and 27-45 years [mid-adults]), forming a baseline to monitor future coverage among U.S. adults. METHODS The final sample included 9,744 individuals (2,522 young adults and 7,222 mid-adults) who participated in the 2017 National Health Interview Survey. The main outcomes were receipt of 1 or more human papillomavirus vaccination and whether the participant had been vaccinated as an adult. Demographic characteristics and healthcare factors were included as covariates in statistical analyses. RESULTS Population estimate of receiving 1 or more human papillomavirus vaccine doses among young adults was 36.3% (female: 51.5%, male: 21.2%; p<0.001) and 9.7% for mid-adults (females: 15.8%, males: 3.2%; p<0.001). In the best-fit model, age was inversely associated with vaccination for mid-adults (female: OR=0.84, 95% CI=0.81, 0.86; male: OR=0.86; 95% CI=0.82, 0.90) and male young adults (OR=0.79, 95% CI=0.71, 0.88). Of the entire vaccinated sample aged 19-45 years, 26.6% had received their first vaccination as an adult (95% CI=23.9, 29.4). CONCLUSIONS These data emphasize the continued need for vaccinating adolescents aged 11-12 years given that few adults were vaccinated against human papillomavirus.

Abstract
PURPOSE/OBJECTIVES In the United States, cervical cancer remains a significant cause of morbidity and mortality. The effect of distance has a complicated relationship with disease characteristics and outcomes in other cancers. The purpose of this study is to investigate the relationship between distance from cancer facility on clinical stage at diagnosis in women with cervical cancer. MATERIALS/METHODS Data were obtained from the National Cancer Database which include patient demographics, disease characteristics, and treatment details. Persons diagnosed with cervical cancer from 2004 to 2015 were included. Subjects were excluded if they had missing information, variant histology, or lived >1,000 miles from their facility resulting in 51,413 persons. Disease was classified as localized (stage 1a-2a) or advanced (stage 2b-4b). Univariate comparisons were performed using analysis of variance and chi-square test. Multivariable logistic regression was used to investigate the effect of distance quartiles on advanced stage while adjusting for other significant variables. RESULTS Mean age was 51.0 years, 16.9% of women were black, 14.7% were Hispanic, 45.0% had private insurance, and 10.7% were uninsured. Overall, 50.9% of women presented with advanced disease. In multivariable analysis, greater distance demonstrated a stepwise risk reduction of advanced disease where those in the farthest quartile had odds ratio of 0.73 (p<0.001) relative to the closest. Additionally, age, race, income, and insurance status significantly affected risk of advanced disease. CONCLUSIONS Distance from cancer facility resulted in lower risk of advanced stage disease at diagnosis. Additional research could elucidate the nuanced relationship between distance, disease characteristics and outcomes in cervical cancer.

Abstract
BACKGROUND Gynecologic oncology surgery is associated with a wide variation in surgical site infection risk. The optimal method for infection prevention in this heterogeneous population remains uncertain. STUDY DESIGN A retrospective cohort study was performed to compare surgical site infection rates for patients undergoing hysterectomy over a 1-year period surrounding the implementation of an institutional infection prevention bundle. The bundle comprised pre-operative, intra-operative, and post-operative interventions including a dual-agent antibiotic surgical prophylaxis with cefazolin and metronidazole. Cohorts consisted of patients undergoing surgery during the 6 months prior to this intervention (pre-bundle) versus those undergoing surgery during the 6 months following the intervention (post-bundle). Secondary outcomes included length of stay, readmission rates, compliance measures, and infection microbiology. Data were compared with pre-specified one-sided exact test, Chi-square test, Fisher's exact test, or Kruskal-Wallis test as appropriate. RESULTS A total of 358 patients were included (178 PRE, 180 POST). Median age was 58 (range 23-90) years. The post-bundle cohort had a 58% reduction in surgical site infection rate, 3.3% POST vs 7.9% PRE (-4.5%, 95% CI -9.3% to -0.2%, p=0.049) as well as reductions in organ space infection, 0.6% POST vs 4.5% PRE (-3.9%, 95% CI -7.2% to -0.7%, p=0.019), and readmission rates, 2.2% POST vs 6.7% PRE (-4.5%, 95% CI -8.7% to -0.2%, p=0.04). Gram-positive, Gram-negative, and anaerobic bacteria were all prevalent in surgical site infection cultures. There were no monomicrobial infections in post-cohort cultures (0% POST vs 58% PRE, p=0.04). No infections contained methicillin-resistant Staphylococcus aureus. CONCLUSION Implementation of a dual antibiotic infection prevention bundle was associated with a 58% reduction in surgical site infection rate after hysterectomy in a surgically diverse gynecologic oncology practice.

Abstract
6022 Background: There are limited chemotherapeutic options for patients (pts) with advanced or recurrent endometrial cancer (EC). Reported objective response rates (ORR) for first-line doxorubicin/cisplatin/ paclitaxel combination therapy was 57%; with a median progression-free survival (PFS) of 8.3 months. The goal of this phase II study was to assess the efficacy and safety of pembrolizumab in combination with standard carboplatin/paclitaxel in pts with measurable advanced or recurrent EC. Methods: This was a single-arm, open-label, multi-center phase II study for pts with RECIST measurable advanced or recurrent EC coordinated by the Big Ten Cancer Research Consortium. Patients may have had received 1 prior platinum-based regimen, with a platinum free interval > 6 months, < one non-platinum chemotherapy, or prior hormonal therapy. Pts received carboplatin AUC 6, paclitaxel 175mg/m2 (CT) and pembrolizumab 200mg IV every 3 weeks for up to 6 cycles; with dose reduced for prior radiation. The primary endpoint was ORR per immune-related RECIST. Planned sample size of 46 subjects provided 77% power to detect 15% ORR improvement compared to historical controls, with one-tailed test and 10% type I error rate. Results: 46 pts were enrolled. Median age was 67 (range: 43-86). 32 pts had recurrent and 14 had primary metastatic EC. Histological types were: 26 endometrioid, 11 serous, 3 clear cell, 6 other. 19 patients had received prior carboplatin/paclitaxel, 23 pelvic EBRT, 14 brachytherapy, 1 adriamycin and 1 hormonal therapy. Grade 3-4 adverse events (AEs) included: laboratory abnormalities (20), hematological (8), metabolism (6), nervous system (4), gastrointestinal (2), and others (6). There were 15 grade 3-4 SAEs occurring in 7 pts: vomiting (1), anaphylaxis (3), fever (2), dehydration (1), syncope (2), vascular (2), fatigue (1), neurological (2), thrombocytopenia (1), and no grade 5 SAEs. 36 patients were evaluable for response at the time of abstract submission. ORR was 77.8% (28/36) and median PFS was 10.55 months. Conclusions: The addition of pembrolizumab to standard of care CT chemotherapy for advanced or recurrent EC induced a clinically significant improvement in ORR compared to historical outcomes and toxicity did not exceed anticipated toxicity with standard treatment, supporting further testing in a phase III trial. Clinical trial information: NCT02549209.

Abstract
Triple-negative breast cancer (TNBC) has few therapeutic targets, making nonspecific chemotherapy the main treatment. Therapies enhancing cancer cell sensitivity to cytotoxic agents could significantly improve patient outcomes. A BCL2-associated agonist of cell death (BAD) pathway gene expression signature (BPGES) was derived using principal component analysis (PCA) and evaluated for associations with the TNBC phenotype and clinical outcomes. Immunohistochemistry was used to determine the relative expression levels of phospho-BAD isoforms in tumour samples. Cell survival assays evaluated the effects of BAD pathway inhibition on chemo-sensitivity. BPGES score was associated with TNBC status and overall survival (OS) in breast cancer samples of the Moffitt Total Cancer Care dataset and The Cancer Genome Atlas (TCGA). TNBC tumours were enriched for the expression of phospho-BAD isoforms. Further, the BPGES was associated with TNBC status in breast cancer cell lines of the Cancer Cell Line Encyclopedia (CCLE). Targeted inhibition of kinases known to phosphorylate BAD protein resulted in increased sensitivity to platinum agents in TNBC cell lines compared to non-TNBC cell lines. The BAD pathway is associated with triple-negative status and OS. TNBC tumours were enriched for the expression of phosphorylated BAD protein compared to non-TNBC tumours. These findings suggest that the BAD pathway it is an important determinant of TNBC clinical outcomes.

Abstract
Uterine tumors resembling ovarian sex cord tumors (UTROSCTs) are rare and commonly characterized as benign tumors, with infrequent reports of metastasis and recurrence. Treatment recommendations have not been well established, particularly for more advanced cases. We present the first reported death from a metastatic UTROSCT, summarize the available literature, and describe characteristics common to UTROSCTs with aggressive features. In this case, a 49-year-old woman presented with abdominal distension and pain; initial imaging and diagnostic workup suggested metastatic epithelial ovarian cancer to be the cause. The patient subsequently underwent neoadjuvant chemotherapy followed by optimal cytoreductive surgery and adjuvant chemotherapy. Final pathology revealed UTROSCT with omental and peritoneal metastases. She then underwent adjuvant chemotherapy with subsequent recurrence and died 15 months after her initial diagnosis. Our analysis of this case and the available literature led us to identify pathologic risk factors that may help predict aggressive UTROSCT behavior.

Abstract
BACKGROUND AND OBJECTIVES To examine association of lympho-vascular space invasion (LVSI) with clinico-pathological factors and to evaluate survival of women with low-grade serous ovarian carcinoma containing areas of LVSI. METHODS This is a multicenter retrospective study examining consecutive cases of surgically treated stage I-IV low-grade serous ovarian carcinoma (n = 178). Archived histopathology slides for the ovarian tumors were reviewed, and LVSI was scored as present or absent. LVSI status was correlated to clinico-pathological findings and survival outcome. RESULTS LVSI was seen in 79 cases (44.4%, 95% confidence interval [CI] 37.1-51.7). LVSI was associated with increased risk of omental metastasis (87.0% vs 64.9%, odds ratio [OR] 3.62, P = 0.001), high pelvic lymph node ratio (median 12.9% vs 0%, P = 0.012), and malignant ascites (49.3% vs 32.6%, OR 2.01, P = 0.035). On multivariable analysis, controlling for age, stage, and cytoreductive status, presence of LVSI in the ovarian tumor remained an independent predictor for decreased progression-free survival (5-year rates 21.0% vs 35.7%, adjusted-hazard ratio 1.57, 95%CI 1.06-2.34, P = 0.026). LVSI was significantly associated with increased risk of recurrence in lymph nodes (OR 2.62, 95%CI 1.08-6.35, P = 0.047). CONCLUSION LVSI in the ovarian tumor is associated with adverse clinico-pathological characteristics and decreased progression-free survival in women with low-grade serous ovarian carcinoma.

Abstract
Abstract
BACKGROUND: Ovarian cancer patients with advanced disease frequently develop ascites. It is currently unclear to what extent the molecular phenotype of the cells in ascites differs from that of the primary ovarian tumor. There is also speculation that the tumor cells in ascites may represent a more treatment resistant cell population. An improved understanding of the biology of the cellular environment in ovarian cancer-related ascites may reveal opportunities to develop new targeted therapies that may not be apparent through analysis of the primary tumor alone. The aim of the study was to evaluate potential biological differences between the cellular environment of primary ovarian tumors and that of the ascites fluid.
METHODS: We performed mRNA expression in n=12 matched pairs of primary serous OVCA tumor and the cellular component of ascites using the HTG Edge System and the EdgeSeq Oncology Biomarker Panel assay. After normalization, log expression values for 2650 genes were compared between tumor and ascites samples using principle component analysis (PCA) modeling. The molecular profiles of primary tumor and ascites were compared using a t-test. Additionally, the CiberSort algorithm was applied to estimate the relative composition of tumor infiltrating lymphocytes in tumor and ascites samples.
RESULTS: PCA modeling demonstrated a clear difference between the primary tumor and ascites samples using all genes. A group comparison (q<0.01, FDR corrected p-value, fold change >2) indicated that 49 genes were differentially expressed between primary tumor and ascites samples. Ascites samples showed significantly higher expression of T-cell markers, CD2, CD3D, CD4, and CD8A, as well as the monocyte/macrophage markers CD14, CCL4, CD163, CCR1, IL10, and ITGAM. CiberSort analysis revealed a high proportion of eosinophils (p <2 x 10^-7) and monocytes (p<0.0002) in ascites as compared to tumor while resting mast cells were proportionately greater in the tumor samples (p < 4 x 10^-5).
CONCLUSIONS: In this study, we report a significant difference in mRNA expression between primary tumors from serous OVCA and ascites. Ascites samples were found to have higher expression of T cell, monocyte and macrophage mRNA. Interestingly, ascites samples also expressed an increased proportion of eosinophils as compared to primary tumor. Eosinophils have been suggested to be essential for CD8+ T-cell mediated tumor rejection and have been associated with improved outcomes in prognosis. We also report an increased proportion of resting mast cells in primary tumor. Mast cells are increasingly thought to play a role in the regulation of tumor growth. In summary, this study demonstrates that molecular profile of cells in ascites is different than that of primary tumor and that this difference is potentially due to immune modulators.

Abstract
e17072 Background: This study aimed to assess the impact of clinical factors, including age and comorbidity, and treatment on outcomes data for women 70 years and older with advanced epithelial ovarian cancer (EOC). Methods: A retrospective chart review was performed on 501 patients with advanced EOC cancer at a single institution between January 1, 2001 and April 1, 2014. Exclusion criteria included non-epithelial histology, stage less than IIIC, and incomplete medical records. Clinical data included disease characteristics, performance measures (ECOG Performance Score, Karnofsky Performance Status, Cumulative Illness Rating Scale for Geriatrics (CIRS-G) score), method of treatment and outcome (surgical debulking status, Mayo Surgical Complexity Score, use of intraperitoneal (IP) chemotherapy, total lines of therapy), and survival data. Results: One hundred twenty-six study subjects (25.15%) were > 70 years old at the time of advanced EOC diagnosis. In a univariate analysis, study subjects > 70 years old were significantly more likely to have a higher CIRS-G score, fewer total lines of therapy, no IP therapy, less enrollment in clinical trials, decreased platinum sensitivity, and worse progression free survival (PFS) and overall survival (OS). A multivariate logistic regression analysis, using variables significant to a level of p < 0.1 in the univariate analysis, demonstrated that patients > 70 years old were significantly more likely to have a higher CIRS-G score (OR1.14, p = 0.00037), worse OS (OR0.98, p = 0.00026), and less likely to have IP therapy (OR0.57, p = 0.04973). Factors independently associated with decreased OS in all study subjects in a multivariate cox proportion hazard model were fewer total lines of therapy (HR0.24, p = 0.0035), lack of IP therapy (HR0.64, p = 0.0036), suboptimal debulking status (HR1.38, p = 0.045), lack of platinum sensitivity (HR0.30, p = 0.00001), and older age (HR1.62, p = 0.0016). Conclusions: In this cohort of patients with advanced EOC, elderly patients had worsened OS. This appears to correlate with comorbidity, lack of platinum sensitivity, along with less aggressive treatment options, number of lines of therapy, IP chemotherapy, and clinical trial enrollments.

Abstract
Although the amount of literature on groups is growing at a rapid rate, concise delineation of the functional and skill expectations of group facilitators is rela tively rare. This article attempts to articulate and discuss a model based on a specific set of assumptions about causality and effectiveness in interactional groups. The authors discuss personal qualities of group facilitators and propose five major functions and seven skill clusters central to effective group facilitation.

Abstract
OBJECTIVE To estimate the cost-effectiveness of providing Haemophilus influenzae type b (Hib) vaccine to children in Moscow in routine immunization services. METHODS The incidence of Hib meningitis among children aged <5 years in Moscow was obtained from a prospective surveillance study undertaken during October 1999-September 2001, with treatment cost data collected for all cases. Sequelae in surviving children were assessed in December 2002. The costs of Hib vaccination in Moscow were estimated assuming a vaccine price of US dollar 5 per dose and the same four-dose schedule and 97% coverage as for diphtheria-tetanus-pertussis vaccine. The most uncertain variables were varied in a sensitivity analysis. RESULTS The annual incidence of Hib meningitis was 5.7 per 100,000 children <5 years. The average treatment cost for an acute Hib meningitis case was US dollar 1296. For a patient with sequelae, the average additional lifetime discounted treatment cost was US dollar 15,820. The total annual cost of Hib vaccination of infants in Moscow was estimated as US dollar 1.5 million per year. In the base case analysis, the cost-effectiveness ratios amount to US dollar 77,503 per Hib meningitis case averted and US dollar 10,842 per discounted disability adjusted life year averted. The break-even vaccine price, where the annual vaccination costs equal annual treatment costs averted, is only US dollar 0.04 per dose in the base case scenario. If discounted indirect costs are included, the break-even vaccine price is US dollar 0.5 per dose. CONCLUSION In Moscow, the incidence of Hib meningitis is low and the costs of hospitalization and subsequent medical treatment are relatively inexpensive. Given these factors, Hib vaccine at US dollar 5 per dose would not be a cost-effective option in Moscow at the present time.

Abstract
IL-2 responses are susceptible to suppression by TGFbeta, a cytokine widely implicated in suppression of inflammatory responses and secreted by many different tumor cell types. There have been conflicting reports regarding inhibition of IL-2-induced STAT3 and STAT5 phosphorylation by TGFbeta and subsequent suppression of immune responses. Using TGFbeta-producing multiple myeloma tumor cells we demonstrate that tumor-derived TGFbeta can block IL-2-induced proliferation and STAT3 and STAT5 phosphorylation in T cells. High affinity IL-2R expression was required for the suppression of IL-2 responses as a novel CD25(-) T cell line proliferated and phosphorylated STAT3 when cultured with tumor cells or rTGFbeta1. Activating T cells with IL-15, which does not use the high affinity IL-2R, completely restored the ability of T cells to phosphorylate STAT3 and STAT5 when cultured with tumor cells. IL-15-treated T cells proliferated normally when cocultured with tumor cells or rTGFbeta1, whereas IL-2 responses were consistently inhibited. Preincubation with IL-15 also restored the ability of T cells to respond to IL-2 by phosphorylating STAT3 and STAT5, and proliferating normally in the presence of tumor cells. IL-2 pretreatment did not restore T cell function. IL-15 also restored T cell responses by T cells from multiple myeloma patients, and against freshly isolated bone marrow tumor samples. Thus, activation of T cells by IL-15 renders T cells resistant to suppression by TGFbeta1-producing tumor cells and rTGFbeta1. This finding may be exploited in the design of new immunotherapy approaches that will rely on T cells avoiding tumor-induced suppression.

Abstract
BACKGROUND The immunogenicity of oral poliovirus vaccine (OPV), particularly the type 3 component, is lower in infants in most developing countries than in infants in industrialized countries. We conducted a multicenter trial in Oman to evaluate the response to a supplemental dose of four poliovirus vaccine formulations. METHODS At nine months of age, infants were randomly assigned to receive inactivated-poliovirus vaccine (IPV), administered subcutaneously; trivalent OPV manufactured in the United States or in Europe; or monovalent type 3 OPV. Serum samples were collected at enrollment and 7 and 30 days later. All of the infants had previously received five doses of OPV. RESULTS We enrolled 1025 infants; 785 (76.6 percent) met all the study requirements. At enrollment, 96.8 percent of the infants were seropositive for poliovirus type 1, 98.0 percent for type 2, and 88.0 percent for type 3. At 30 days there were no significant increases in type 3 seroprevalence or in the median antibody titer in the groups of infants who received OPV. Among the recipients of IPV, type 3 seroprevalence increased from 87.8 percent at enrollment to 97.1 percent at 30 days (P<0.001), and the median antibody titer increased from 1:228 to 1:1448 or higher (P<0.001). The rapid initial increase in the antibody titer suggests a secondary immune response. CONCLUSIONS A supplemental dose of IPV has excellent immunogenicity and leads to increases in the titer of antibodies against type 3 poliovirus, whereas supplemental doses of the oral vaccines do not have these effects.

Abstract
We have performed an F2 genetic screen to identify lethal mutations that map to the 44D-45B region of the Drosophila melanogaster genome. By screening 8500 mutagenized chromosomes for lethality over Df(2R)Np3, a deficiency which encompasses nearly 1% of the D. melanogaster euchromatic genome, we recovered 125 lines with lethal mutations that represent 38 complementation groups. The lethal mutations have been mapped to deficiencies that span the 44D-45B region, producing an approximate map position for each complementation group. Lethal mutations were analyzed to determine the phase of development at which lethality occurred. In addition, we have linked some of the complementation groups to P element-induced lethals that map to 44D-45B, thus possibly providing new alleles of a previously tagged gene. Some of the complementation groups represent potentially novel alleles of previously identified genes that map to the region. Several genes have been mapped by molecular means to the 44D-45B region, but do not have any reported mutant alleles. This screen may have uncovered mutant alleles of these genes. The results of complementation tests with previously identified genes in 44D-45B suggests that over half of the complementation groups identified in this screen may be novel.

Abstract
The germ cell precursors of Drosophila (pole cells) are specified by maternally supplied germ plasm localized to the posterior pole of the egg. One component of the germ plasm, germ cell-less (gcl) mRNA, encodes a novel protein which specifically localizes to the nuclear envelope of the pole cell nuclei. In addition to its maternal expression, gcl is zygotically expressed through embryonic development. In this report, we have characterized a null allele of germ cell-less to determine its absolute requirement during development. We have found that gcl activity is required only for the establishment of the germ cell lineage. Most embryos lacking maternal gcl activity fail to establish a germline. No other developmental defects were detected. Examination of germline development in these mutant embryos revealed that gcl activity is required for proper pole bud formation, pole cell formation, and pole cell survival. Using this null mutant we have also assayed the activity of forms of Gcl protein with altered subcellular distribution and found that localization to the nuclear envelope is crucial for promoting pole cell formation, but not necessary to initiate and form proper pole buds. These results indicate that gcl acts in at least two different ways during the establishment of the germ cell lineage.

Abstract
Effective attenuated live virus mumps vaccines have been available for more than 30 years. Vaccine strains have been developed on various cell culture systems; the attenuated mumps virus strain most commonly used is the Jeryl Lynn strain. Various vaccines differ in their immunogenicity, efficacy and associated adverse events. It is estimated that the immunization coverage needed to block the transmission of mumps virus is at least 70%. Models indicate that low to moderate levels of mumps vaccine coverage may actually increase the number of susceptibles and the number of cases in older age groups. Benefit-cost analyses in a number of countries have found that the introduction of mumps vaccine is economically justifiable, as vaccination can avert the considerable medical and economic costs associated with mumps morbidity. Countries that do not immunize against mumps continue to register high mumps morbidity, and pay a high toll from neurological and other complications of mumps. Poland, which already has a high level of measles vaccine coverage, should make efforts to replace monovalent measles vaccine with trivalent measles-mumps-rubella (MMR) vaccine.

Abstract
Mumps is an acute infectious disease caused by a paramyxovirus. Although the disease is usually mild, up to 10% of patients can develop aseptic meningitis; a less common but more serious complication is encephalitis, which can result in death or disability. Permanent deafness, orchitis, and pancreatitis are other untoward effects of mumps. Based on data reported to WHO up to April 1998, mumps vaccine is routinely used by national immunization programmes in 82 countries/areas: 23 (92%) of 25 developed countries, 19 (86%) of 22 countries with economies in transition (mainly the Newly Independent States of the former Soviet Union), and 40 (24%) of 168 developing countries. Countries that have achieved high coverage have shown a rapid decline in mumps morbidity. Furthermore, in many of these countries, mumps-associated encephalitis and deafness have nearly vanished. This review considers the disease burden due to mumps; summarizes studies on the immunogenicity, efficacy, and safety of different strains of mumps vaccine; and highlights lessons learned about implementing mumps immunization in different countries. Countries already using mumps vaccine should monitor immunization coverage and establish routine mumps surveillance with investigation of outbreaks. Where mumps is targeted for elimination, countries need to add a second dose of mumps vaccine for children, keeping in mind that the disease may still occur in susceptible adults.

Abstract
Since the mid-1980s, there has been growing interest in adapting the lot quality (LQ) technique to monitor the quality of health care services, especially in developing countries. This global review has identified a total of 34 LQ surveys conducted from 1984 to 1996 in Africa, the Americas, Europe, South-East Asia, and the Western Pacific. Health care parameters assessed in the surveys varied and some surveys assessed more than 1 health parameter: 24 surveys assessed immunization coverage, 9 examined women's health issues such as family planning and antenatal care, 5 assessed use of oral rehydration therapy, 5 estimated disease incidence, and 3 others evaluated health worker performance. These studies indicate that LQ is a practical, relatively low-cost field method which is increasingly being applied in health programmes.

Abstract
Mumps is commonly considered a "mild" infectious disease in children because death due to mumps is very rare. However, mumps causes a high rate of complications in young adults, and its burden should not be underestimated. Before the introduction of vaccine, mumps was a common infectious disease with high incidence rates which exceeded 100 per 100,000 population in most countries. Poland continues to belong to the group of countries, which do not use mumps vaccine. In Poland, the number of reported mumps cases per year ranges from 40,000 to 220,000, yielding an annual incidence rates of 110 and 570 per 100,000 population. It is estimated that each year in Poland, mumps causes 1000 cases of aseptic meningitis (range 400 to 2,200), 100 cases of encephalitis, 250 to 1375 cases of epidymo-orchitis in post-pubertal men, 50-275 cases of oophoritis in women. The age distribution of mumps cases is characteristic for a country that does not use mumps vaccine. For more that 20 years, the highest mumps incidence has occurred in children aged 5-9 years. In many countries the number of reported cases has declined significantly following the introduction of mumps vaccine, and in several countries the incidence has fallen to less than 1 per 100,000 population. Several countries using mumps vaccine have reported a shift in the age distribution of mumps cases, with an increased incidence in older children and young adults. Countries with high levels of coverage with measles-mumps-rubella (MMR) vaccine have nearly eliminated encephalitis associated with these diseases. A few countries using mumps vaccine have experienced relative resurgence of the disease, either due to incomplete vaccine coverage of certain age groups (USA) or problems with the long-term immunogenicity of mumps vaccine based on the Rubini strain (Portugal, Switzerland).

Abstract
Abstract
The production of proinflammatory cytokines can be regulated by several factors that exert activating or inhibitory effects. IL-4, IL-10, IL-13, TGF-beta, and PGE2 have demonstrated a very wide range of potent macrophage-deactivating activities and, specifically, down-regulation of the production of many proinflammatory monokines. IL-12 plays a key role during immune response by providing a link between natural resistance and adaptive immunity. We and others have previously shown an impairment in IL-12 production by PBMC from HIV-1-infected individuals in response to various stimuli, but defining the mechanism responsible remains elusive. In this study, we observed that pretreatment of PBMC from patients with IL-4 or IL-13 for 24 h primes the cells for enhanced production of IL-12 in response to Staphylococcus aureus, and almost completely restores their deficient IL-12 production when compared with healthy controls. Although this priming effect was completely abrogated by IL-10 and PGE2, IL-10 was produced equivalently by untreated and IL-4- or IL-13-pretreated PBMC from both patients and controls. Additionally, indomethacin, which shuts off PGE2 synthesis, and cAMP-blocking reagents failed to restore or enhance IL-12 production. The priming effect of IL-4 and IL-13 is at the transcription level for both p40 and p35 genes. This complete restoration of IL-12 production by Th2-associated cytokines was unexpected in light of the mutually antagonistic roles of IL-12 and IL-4 in promoting Th1 or Th2 immune responses.

Abstract
Sex determination in Silene latifolia is controlled by heteromorphic sex chromosomes. Female flowers have five fused carpels and ten arrested stamen primordia. The male-determining Y chromosome overrides female development to suppress carpel formation and promote stamen development. The isolation and characterization of two S. latifolia. Male enhanced cDNAs, Men-9a and Men-9b, which probably represent different alleles of a novel gene are reported here. Men-9a and Men-9b share 91.8% coding sequence nucleotide identity, yet only 85.4% amino acid identity. The Men-9 cDNAs are related to the previously reported MROS3 cDNA from S. latifolia. However, MROS3 is not present in the S. latifolia population used in these studies and the expression dynamics of Men-9a and Men-9b contrast dramatically with those reported for MROS3. Men-9 cDNAs are expressed primarily in anthers of young male flowers, with highest expression in 1-2 mm buds. Men-9 expression is also observed at a low level in female flowers. In situ hybridization analysis reveals two phases of Men-9 expression. The first phase is during a common stage of early stamen development in male and female flowers prior to stamen arrest in female flowers. The second phase of Men-9 expression is maximal in the epidermis and endothecium of Y chromosome- and Ustilago violacea-induced stamens; expression in male and female flowers extends to the epidermis of the staminal nectaries with strict boundaries at the second and fourth whorls, Men-9 gene expression therefore delineates the boundaries of the third floral whorl in S. latifolia flowers.

Abstract
We have embarked on a molecular cloning approach to the investigation of sex determination in Silene latifolia Poiret, a dioecious plant species with morphologically distinguishable sex chromosomes. One of our key objectives was to define a range of genes that are up-regulated in male plants in response to Y chromosome sex-determination genes. Here we present the characterization of eight male-specific cDNA sequences and classify these according to their expression dynamics to provide a range of molecular markers for dioecious male flower development. Genetically female S. latifolia plants undergo a partial sex reversal in response to infection by the parasitic smut fungus Ustilago violacea. This phenomenon has been exploited in these studies; male-specific cDNAs have been further categorized as inducible or noninducible in female plants by smut fungus infection. Analysis of the organ-specific expression of male-specific probes in male and female flowers has also identified a gene that is regulated in a sex-specific manner in nonreproductive floral tissues common to both male and female plants. This observation provides, to our knowledge, the first molecular marker for dominant effect of the Y chromosome in nonreproductive floral organs.

Abstract
We have established in vitro assays that allow the examination of co-stimulatory function of rheumatoid arthritis (RA) antigen-presenting cells (APC). Synovial fluid (SF) and peripheral blood (PB) APC co-stimulatory ability was compared in the activation of peptide-specific human T-cell clones. T-cell receptor (TCR) stimulation by peptide or anti-CD3 antibody allowed the direct comparison of SF and PB APC co-stimulatory activity, separately from their ability to process antigen. SF APC from 15 RA patients consistently enhanced T-cell proliferation when compared to their PB counterparts. Moreover, increasing the numbers of PB APC present resulted in only a minor increase in T-cell proliferation, failing to achieve levels stimulated by SF APC. We propose that the enhanced co-stimulatory function of synovial APC may be a significant factor in the persistence of local immune responses in RA.

Abstract
Seroprevalence and geometric mean titers (GMTs) were compared at 6 and 10 months after vaccination with monovalent type 1 oral poliovirus vaccine (OPV) at 6 months and trivalent OPV at 7 and 9 months. Group 1 had received 4 doses of OPV, group 2 OPV at birth and 3 doses of OPV and inactivated poliovirus vaccine (IPV), and group 3 placebo at birth and 3 doses of IPV. A total of 547 infants completed the study. At 10 months, seroprevalence to poliovirus type 1 was 98%, 99%, and 98% in groups 1, 2, and 3; 100%, 100%, and 98% to poliovirus type 2; and 80%, 96%, and 91% to poliovirus type 3. Differences in seroprevalence among the groups were significant for poliovirus type 3 (P < .001). Between 6 and 10 months, significant increases in seroprevalence and GMTs occurred for poliovirus type 1 but not for types 2 and 3. Two OPV doses following 3 IPV doses did not significantly increase seroprevalence or raise GMTs for poliovirus types 2 and 3; however, significant increases were found for poliovirus type 1, which may have benefitted from monovalent type 1 administration.

Abstract
Congenital rubella syndrome (CRS) can lead to deafness, heart disease, and cataracts, and a variety of other permanent manifestations. In developing countries, the burden of CRS has been assessed as follows: by surveillance of CRS; by surveillance of acquired rubella; by age-stratified serosurveys; and by serosurveys documenting the rubella susceptibility of women of childbearing age. During rubella outbreaks, rates of CRS per 1000 live births were at least 1.7 in Israel, 1.7 in Jamaica, 0.7 in Oman, 2.2 in Panama, 1.5 in Singapore, 0.9 in Sri Lanka, and 0.6 in Trinidad and Tobago. These rates are similar to those reported from industrialized countries during the pre-vaccine era. Special studies of CRS have been reported from all WHO regions. Rubella surveillance data show that epidemics occur every 4-7 years, similar to the situation in Europe during the pre-vaccination era. In developing countries, the estimated average age at infection varies from 2-3 years to 8 years. For 45 developing countries we identified serosurveys of women of childbearing age that had enrolled > or = 100 individuals. The proportion of women who remained susceptible to rubella (e.g. seronegative) was < 10% in 13 countries. 10-24% in 20 countries, and > or = 25% in 12 countries. Discussed are methods to improve the surveillance of rubella and CRS in developing countries.

Abstract
Pertussis is a serious disease for children in all countries, but it is more severe in the developing world. Disease incidence, complication rates and case fatality rates are highest in infants: unimmunized and incompletely immunized young children are also at risk in adults, pertussis is usually mild or asymptomatic, but older individuals may serve as reservoirs for transmission. Some 70 million cases of pertussis were prevented in 1994 due to immunization with the current whole cell vaccine. WHO emphasizes the importance of early completion of the primary series of vaccinations, with three doses of diphtheria-tetanus-pertussis (DTP) vaccine one month apart starting at six weeks of age. For the past five years, nearly 80% of infants worldwide have received three DTP doses by their first birthday. Despite this, an estimated 40 million cases of pertussis occurred in 1994, indicating the need to increase coverage. The challenge is to reach 90% coverage of infants in all countries by the year 2000 but this will require further efforts to improve immunization programmes.

Abstract
In 1995, the WHO Global Programme for Vaccines and Immunization established a Vaccine Trial Registry. As of September 1996, this registry included 50 WHO-supported vaccine trials, of which 25 (50%) were completed studies. The vaccines most frequently tested have been against measles (9 trials), poliovirus (8 trials), cholera (8 trials), enterotoxigenic Escherichia coli (4 trials), and pneumococcus (4 trials). Nearly 80% of these trials have been conducted in developing countries, with the largest number being in Africa. Among the 25 completed trials, outcomes measured were immune response (24 trials), adverse reactions (13 trials), morbidity (4 trials), and mortality (1 trial). WHO's contributions to these studies include direct funding, assistance with study design, site visits, data analysis, vaccine procurement, and vaccine potency testing.

Abstract
In 1995-96 we conducted a review of rubella immunization strategies. Worldwide, 78 countries (more than one-third) reported a national policy of using rubella vaccine. This was closely related to country economic status. Based on the United Nations country classification, rubella vaccine is used in 92% of industrialized countries, 36% of those with economies-in-transition, and 28% of developing countries. Cases of congenital rubella syndrome (CRS) may be prevented as follows: by providing direct protection to women and/or schoolgirls (a selective vaccination strategy); by vaccinating boys and girls to provide indirect protection by reducing the transmission of rubella virus (a childhood vaccination strategy); or by a combination of these approaches (a combined strategy). A combined strategy was most commonly reported (60% of countries); seven countries (9%) reported a selective strategy; and 24 countries (31%) reported only childhood immunization. Experience has shown that it is essential to include vaccination of women of childbearing age in any rubella control strategy. Childhood vaccination alone may pose a risk of an increase in CRS cases. Although many countries have introduced rubella vaccine, few report any data on the impact of vaccination. Countries using rubella vaccine need to establish surveillance for rubella and CRS and monitor coverage in each of the target groups.

Abstract
A massive diphtheria epidemic in Eastern Europe has resulted in increased anxiety that this disease could spread to other countries. This fear is realistic because there is a gap in the diphtheria immunity in large segments of the adult population in many industrialized countries. Experience to date suggests that an immunity gap in adults coupled with the presence of large numbers of susceptible children and adolescents creates the potential for an extensive epidemic. To prevent epidemics, countries should consider the immunogenicity and duration of protection provided by diphtheria toxoid given to children in the primary series and as booster doses. This paper reviews general issues related to the formulation of diphtheria immunization strategies, especially the need for booster doses in adults and the rationale for use of lower-strength diphtheria toxoid for persons older than 6 years of age.

Abstract
Seroresponses to trivalent oral poliovirus vaccine are not uniform throughout the world. Definition of the variables that determine successful immunization is vital to ensure global polio eradication. One such variable may be dosage interval. To investigate this effect 108 infants were enrolled in a clinical trial and randomly assigned to receive three doses of trivalent oral poliovirus vaccine (standard United States formulation) at 2, 3 and 4 or 2, 4 and 6 months of age. After three doses of vaccine given before 6 months of age, immunity was virtually complete for each of the three poliovirus types in both groups. After two doses the seroresponse rate to each type was less with the shorter dose interval. However the difference was not significant (P = 0.15) in the sample size studied. Such responses differ markedly from those seen in developing countries, where four or more doses of vaccine may fail to provide complete protection. Differences other than dosage interval must contribute to those failures.

Abstract
In the past, diphtheria was considered one of the most serious childhood diseases because it took a heavy toll in health and life among preschool-aged children. Prior to the widespread availability of diphtheria toxoid, nearly 70% of cases were in children younger than 15 years of age. In the industrialized countries, immunization against diphtheria became widespread in the 1940s and 1950s. This led to a marked decrease in the incidence of diphtheria. There was also a decrease in circulating toxigenic Corynebacterium diphtheriae organisms, resulting in less natural boosting of antibody levels. This had led to gaps in the immunity of the adult population. Since 1990, diphtheria has made a spectacular comeback in several European countries, with a high proportion of cases in adults. In developing countries, immunization of infants with diphtheria toxoid was introduced with the Expanded Programme on Immunization in the late 1970s. Coverage rose slowly to 46% in 1985 and 79% in 1992. Because the pool of immunized persons is not yet large, the process of maintaining immunity still operates through natural mechanisms, including frequent skin infections caused by C. diphtheriae. But recently, several developing countries where coverage has been high for 5-10 years have reported diphtheria outbreaks. These outbreaks have been characterized by high case fatality rates, a large proportion of patients with complications, and their occurrence in both young and older age groups. In all countries, priority should be given to efforts to reach at least 90% coverage with three doses of diphtheria toxoid in children below one year of age. In countries where diphtheria has been successfully controlled, immunity levels should be maintained by booster doses.

Abstract
Following the introduction of routine immunization with diphtheria toxoid in the 1940s and 1950s, diphtheria incidence declined dramatically in countries of the industrialized world. At the beginning of the 1980s many of these countries were progressing toward elimination of the disease. However, since the mid-1980s there has been a striking resurgence of diphtheria in several countries of Eastern Europe. For 1993, WHO received reports of 15,211 diphtheria cases in Russia and 2,987 cases in Ukraine. The main reasons for the return of diphtheria in these countries were: decreasing immunization coverage among infants and children waning immunity to diphtheria in adults, movements of the population during the last few years, and an irregular supply of vaccines. The outbreak spread to neighboring countries and in 1993 cases were reported in Azerbaijan, Belarus, Estonia, Finland, Kazakhstan, Latvia, Lithuania, Poland, Tajikistan, Turkey, and Uzbekistan. Epidemiological patterns of diphtheria are changing in developing countries, and the disease seems to be following patterns seen in industrialized countries 30 to 40 years ago. In developing countries, routine immunization against diphtheria was introduced in the late 1970s with the Expanded Programme on Immunization. In these countries, coverage of infants with 3 doses of diphtheria toxoid reached 46% in 1985, and 79% in 1992. Recent diphtheria outbreaks in Algeria, China, Ecuator, Jordan, Lesotho and Sudan demonstrate a shift in the age distribution of cases to older children and adults. Rapid clinical and public health responses are required to control diphtheria outbreaks. Three major measures are indicated: high immunization coverage of target groups, prompt diagnosis and management of diphtheria cases, and rapid identification of close contacts with their effective management to prevent secondary cases.

Abstract
BACKGROUND Our preliminary results showed that pentoxifylline improves survival after cecal ligation and puncture (CLP), even though in this model inhibition of tumor necrosis factor (TNF) activity decreases survival. In this study we tested the hypothesis that pentoxifylline improves survival after CLP, not by inhibiting TNF synthesis but by exerting its effect on leukocyte adhesiveness, neutrophil sequestration, recruitment of cells into the focus of sepsis, and interleukin-1 (IL-1) expression. METHODS Pentoxifylline, 10 or 100 mg/kg/day, was administered to mice after CLP by infusion for 3 days. The following was measured at 24 hours for the group with improved survival: (1) serum TNF by enzyme-linked immunosorbent assay, (2) TNF and IL-1 beta mRNAs in lung and peritoneal macrophages by the differential polymerase chain reaction, (3) lung myeloperoxidase by a colorimetric assay, (4) leukocyte CD11b/CD18 by flow cytometry, and (5) peritoneal exudate cells by manual counting. RESULTS Only the low-dose pentoxifylline increased survival. Pentoxifylline reduced IL-1 beta mRNA expression in lung and peritoneal macrophages but not TNF mRNA or immunoreactive TNF in the serum. The myeloperoxidase content of lung was reduced by pentoxifylline, but leukocyte CD11b/CD18 expression did not change. Pentoxifylline increased the number of cells in the peritoneum after CLP. CONCLUSIONS Pentoxifylline improves survival after CLP without inhibiting TNF synthesis or expression of CD11b/CD18 on leukocytes. Pentoxifylline treatment reduced lung neutrophil sequestration and IL-1 beta mRNA levels and increased cell recruitment in the peritoneum.

Abstract
Countries are increasingly requesting guidance on carrying out acute flaccid paralysis (AFP) surveillance, aimed at detecting and confirming all cases of acute paralytic poliomyelitis. The experience of Oman provides many lessons in this respect. AFP surveillance in Oman was established systematically. First, an epidemiologist was assigned to coordinate surveillance, and a laboratory for performing polio-virus isolation was identified. Next, operational guidelines for AFP surveillance were developed and widely promoted among health staff. The quality of the system has been monitored for more than 3 years with selected performance indicators. From January 1990 to April 1993, 49 AFP cases were reported, corresponding to an average annual rate of 2.1 AFP cases per 100,000 children aged less than 15 years. A total of 98% of the AFP cases were investigated within 48 hours of being reported; two stool samples were obtained from 94% of the cases. Following complete investigation, nearly a third of the reported AFP cases were classified as being clinically compatible with Guillain-Barré syndrome. Four AFP cases, all reported in 1991, were confirmed to be due to wild type 3 poliovirus. Because AFP surveillance detected these cases rapidly, Oman was able to carry out outbreak control measures promptly and more than 350,000 extra doses of oral poliovirus vaccine were delivered to children under 6 years of age.

Abstract
In 1988 the World Health Assembly set the goal of global poliomyelitis eradication by the year 2000. Substantial progress has been made, and 143 countries reported no poliomyelitis cases associated with the wild virus in 1993. This article reviews the immunological considerations relevant to interrupting the transmission of wild polioviruses with vaccines. Although serum immunity prevents poliomyelitis in the individual, it is local immunity that is important in preventing the transmission of polioviruses in the community. Natural infection and vaccination with oral polioviruses vaccine (OPV) produce local immunity in the intestine and the nasopharynx in about 70-80% of individuals. In contrast, inactivated poliovirus vaccine (IPV) produces local intestinal immunity in only 20-30% of the individuals. With either vaccine, however, a substantial proportion of the immunized population can transmit the wild virus. Moreover, although serum immunity is long-lasting, limited data suggest that local immunity may not be as persistent. To interrupt the transmission of wild polioviruses efforts should be made to achieve and sustain high levels of poliovirus vaccine coverage. Recent outbreaks show that wild poliovirus poses a risk for unimmunized individuals, even when overall coverage levels are high. Delivery of poliovirus vaccine to hard-to-reach populations will be of increasing importance as countries progress toward the final stages of poliomyelitis eradication. The immunization status of persons from poliomyelitis-free countries should be updated prior to travel to poliomyelitis-endemic areas.
