Could it? Should it? Cognitive reflection facilitates children's reasoning about possibility and permissibility.

Children can be unduly skeptical of events that violate their expectations, claiming that these events neither could happen nor should happen even if the events violate no physical or social laws. Here, we explored whether children's reasoning about possibility and permissibility-modal cognition-is aided by cognitive reflection, or the disposition to privilege analysis over intuition. A total of 99 children aged 4 to 11 years judged the possibility and permissibility of several hypothetical events, and their judgments were compared with their scores on a developmental version of the Cognitive Reflection Test (CRT-D). Children's CRT-D scores predicted their ability to differentiate possible events from impossible ones and their ability to differentiate impermissible events from permissible ones as well as their ability to differentiate possibility from permissibility in general. Such differentiations were predicted by children's CRT-D scores independent of age and executive function. These findings suggest that mature modal cognition may require the ability to reflect on, and override, the intuition that unexpected events cannot happen.

IgG4-related disease mimicking gynecologic malignancy.

Immunoglobulin G4 (IgG4) related disease is a systemic disease that causes fibrosis, tumor-like nodules, and lymphoid hyperplasia with infiltration of IgG4 positive plasma cells. It can manifest in many organ systems; however, there are few cases that report gynecologic organ involvement. It is crucial to correctly diagnose IgG4-related disease versus malignancy because the former is treated with glucocorticoids or rituximab. In this case report, we describe two patients in which IgG4-related disease mimics gynecologic cancer. In the first case, an 85 year old woman presented with diffuse lymphadenopathy and a uterine mass concerning for malignancy. Biopsies were negative for carcinoma. Inguinal lymph node biopsy demonstrated IgG4 positive plasma cells and the patient was treated with rituximab therapy given concurrent severe rheumatoid arthritis. In the second case, a 35 year old woman under surveillance for Stage IB2 squamous cell carcinoma of the cervix (status post definitive chemoradiation therapy) presented with fluorodeoxyglucose (FDG) avid paraaortic lymph nodes on positron emission tomography (PET) imaging with subsequent negative paraaortic lymph node biopsies. Serial imaging and biopsies remained inconclusive despite ongoing diffuse lymphadenopathy and clinical concern for recurrence. Supraclavicular lymph node excision was performed which demonstrated lymphoid hyperplasia with increased IgG4 plasma cells and no evidence of carcinoma, supporting the diagnosis of IgG4-related disease. The patient was treated with high dose steroids with clinical improvement and resolution of abnormal imaging findings. We demonstrate that IgG4-related disease can present with FDG-avid lesions on PET imaging and lymphadenopathy that mimics primary or recurrent gynecologic malignancy. While rare, we conclude the IgG4-related disease is an important differential diagnosis to consider in the workup of primary or recurrent gynecologic malignancy and highlights the value of PET imaging to identify unusual patterns of lymphadenopathy and guide histologic confirmation of disease.

Communicating the Gynecologic Brachytherapy Experience (CoGBE): Clinician perceived benefits of a graphic narrative discussion guide.

PURPOSE: Many current radiotherapy patient education materials are not patient-centered. An interprofessional team developed Communicating the Gynecologic Brachytherapy Experience (CoGBE), a graphic narrative discussion guide for cylinder, intracavitary, and interstitial high-dose-rate (HDR) gynecologic brachytherapy. This study assesses perceived clinical benefits, usability, and anxiety-reduction of CoGBE. METHODS AND MATERIALS: An electronic survey was sent to members of the American Brachytherapy Society. Participants were assigned to assess one of the three modality-specific CoGBE versions using a modified Systems Usability Scale (SUS), modified state-trait anxiety index (mSTAI), and Likert-type questions. Free response data was analyzed using modified grounded theory. RESULTS: Median modified SUS score was 76.3 (interquartile range [IQR], 71.3-82.5) and there were no significant differences between guide types. Median mSTAI was 40 (IQR, 40-43.3) for all guides collectively. The cylinder guide had a significantly higher median mSTAI than the intracavitary and interstitial guides (41.6 vs. 40.0 and 40.0; p = 0.04) suggesting the cylinder guide may have less impact on reducing anxiety. Most respondents reported that CoGBE was helpful (72%), would improve patient understanding (77%) and consultation memorability (82%), and was at least moderately likely to be incorporated into their practice (80%). Qualitative analysis themes included personalization and relatability (positive); generalizability (negative); illustrations (both). CONCLUSIONS: Clinicians rate CoGBE as usable with potential to reduce patient anxiety, especially with more invasive treatment modalities including intracavitary or interstitial high-dose-rate. CoGBE has the potential to improve patient-clinician communication for a wider range of patients due to its accessible, adaptable, and patient-centered design.

Foster Caregivers' Perceptions of Children's Sleep Patterns, Problems, and Environments.

OBJECTIVE: The disparity of problems, impairments, and disorders among children in foster care is well-documented and spans virtually every domain of functioning. Sleep, however, has received minimal attention among this vulnerable group, which is concerning given the multitude of ways sleep affects children's development, health, and behavior. METHODS: A total of 485 foster caregivers from across the United States completed a survey including quantitative items and qualitative, open-ended questions about sleep and related health and behavior for one child (M = 6.4 years, SD = 2.2; range 4-11 years) currently in their care. RESULTS: Overall, caregivers reported developmentally appropriate child sleep and wake times; however, difficulty falling asleep (avg. 46 min per night) and staying asleep (avg. 34 min awake overnight) were common. Additionally, a high prevalence of sleep-related problems was reported including moving to someone else's bed during the night (85.8%), nightmares (51.2%), sleep terrors (26.4%), snoring (32.8%), bedwetting (31.6%), and teeth grinding (21.8%). Qualitative responses indicated emotional and behavioral challenges at bedtime, particularly elevated fear, and anxiety. CONCLUSIONS: Findings are consistent with previous work finding significant health disparities among children placed in foster care. Results highlight a need for trauma-informed, behavioral sleep interventions for this pediatric population which might serve to reduce other health disparities.

How Are the Sleep Problems of Children in the US Foster Care System Addressed?

OBJECTIVE: Evidence of poor sleep health among children in foster care continues to mount, but information about whether and how sleep problems are addressed is unavailable. The goal of this study was to begin to fill these significant knowledge gaps. METHODS: Four hundred eighty-five foster caregivers from across the United States completed a survey focused on the sleep health of one child, 4 to 11 years ( M = 6.4; SD = 2.2) currently in their care. Caregivers provided quantitative and qualitative responses to questions regarding training, information, and services received in relation to their child's sleep. Caregivers also reported on the factors and strategies they perceived as most important for helping children in their care sleep well. RESULTS: Only 13% of caregivers reported receiving any information/education about sleep from agencies or case workers, whereas 55% had sought help from a health provider related to their child's sleep. Nearly half of all caregivers (46%) reported giving their child melatonin. Caregivers reported that a bedtime routine/consistency, reassurance of safety/love, and a calming environment were most important for helping their child sleep well. A recurrent theme in qualitative responses was a need to mitigate child fear/anxiety at night. CONCLUSION: Children in foster care face a range of risk factors that increase the likelihood of poor/insufficient sleep, but these findings suggest this critical aspect of health requires greater clinical and research attention. As these data were collected during the initial months of the COVID-19 pandemic, replication studies are necessary.

Lessons learned: Telemedicine patterns and clinical application in patients with gynecologic cancers during COVID-19.

Objective: To describe the use of telemedicine in gynecologic oncology and identify patient characteristics associated with telemedicine use during COVID-19. Methods: Single-institution retrospective chart review of patients with gynecologic cancer who participated in in-person and telemedicine visits (video and telephone) from January 2019 to November 2020. Patient characteristics, visit and treatment characteristics were collected. Comparisons between 2019 and 2020 and between in-person and telemedicine visits were performed. Cancer-specific visit details were described. Results: From January to November 2020, 2,039 patients attended 5240 ambulatory visits in our gynecologic oncology outpatient clinics with 4,304 (82.1%) in-person visits, 512 (9.8%) video telemedicine visits, and 424 (8.1%) telephone visits. In 2020, 936 (45.9%) patients participated in a telemedicine visit. Demographic characteristics did not differ between those who participated in any telemedicine versus in-person visits (p > 0.05). Black patients represented a larger share of telephone visits but this was not significant. Patients aged > 65 years were more likely to use the telephone for a visit and less likely to use video visits compared to their younger counterparts. The majority of patients who attended a telemedicine visit also attended a visit in-person (88.0%). The most common purpose of the telemedicine visits was to discuss results and/or treatment plans (46%) with other appointments occurring for treatment check-ins and clinical trials. Conclusions: The use of telemedicine drastically increased in 2020. Patient demographics were not different between in-person and telemedicine visits except that older patients were more likely to use telephone visits over video visits. Telemedicine can be used for a variety of care needs in gynecologic oncology but further work needs to be done to optimize implementation, assess cost-effectiveness and patient outcomes.

Differences in Sociodemographic Disparities Between Patients Undergoing Surgery for Advanced Colorectal or Ovarian Cancer.

BACKGROUND: Cytoreductive surgery (CRS) for ovarian cancer with peritoneal metastases (OPM) is an established treatment, yet access-related racial and socioeconomic disparities are well documented. CRS for colorectal cancer with peritoneal metastases (CRPM) is garnering more widespread acceptance, and it is unknown what disparities exist with regards to access. METHODS: This retrospective cross-sectional multicenter study analyzed medical records from the National Cancer Database from 2010 to 2015. Patients diagnosed with CRPM or ORP only and either no or confirmed resection were included. Patient- and facility-level characteristics were analyzed using uni- and multivariable logistic regressions to identify associations with receipt of CRS. RESULTS: A total of 6634 patients diagnosed with CRPM and 14,474 diagnosed with OPM were included in this study. Among patients with CRPM, 18.1% underwent CRS. On multivariable analysis, female gender (odds ratio [95% CI] 2.04 [1.77-2.35]; P < 0.001) and treatment at an academic or research facility (OR 1.55 [1.17-2.05]; P = 0.002) were associated with CRS. Among patients with OPM, 87.1% underwent CRS. On multivariable analysis, treatment at facilities with higher-income patient populations was positively associated with CRS, while age (OR 0.97 [0.96-0.98]; P < .0001), use of nonprivate insurance (OR 0.69 [0.56-0.85]; P = 0.001), and listed as Black (OR 0.62 [0.45-0.86]; P = 0.004) were negatively associated with CRS. CONCLUSION: There were more systemic barriers to CRS for patients with OPM than for patients with CRPM. As CRS becomes more widely practiced for CRPM, it is likely that more socioeconomic and demographic barriers will be elucidated.

Guillain-Barré Syndrome in a Child With COVID-19 Infection.

Guillain-Barré syndrome (GBS) is characterized by a monophasic, ascending, and symmetrical paralysis with areflexia that progresses over days to weeks. It is typically a postinfectious autoimmune process that leads to destruction of myelin. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan, China, in late 2019 and rapidly spread around the world, causing a pandemic of novel coronavirus disease 2019 (COVID-19). There have been scattered reports of adults with possible GBS and concurrent evidence of COVID-19, but no previous reports in children. The patient is an 8-year-old boy who presented to the emergency department with progressive, ascending weakness with areflexia. He was intubated for airway protection because of poor secretion control. MRI of the spine revealed abnormal enhancement of posterior nerve roots. A lumbar puncture revealed albuminocytologic dissociation with 1 nucleated cell per mm3 and a protein level of 620 mg/dL. Electrodiagnostic findings were compatible with sensorimotor demyelinating polyneuropathy. The lumbar puncture, MRI, and electrodiagnostics were all consistent with GBS. Results of SARS-CoV-2 nucleic acid amplification and SARS-CoV-2 immunoglobulin G antibody tests were positive. Treatment was initiated with intravenous immunoglobulin; he received a total of 2 g/kg. His neurologic examination revealed improvement in the subsequent days. He was extubated after 4 days of intubation. This case is the first reported case of a child with GBS in the setting of an acute COVID-19 infection. This case reveals the wide scope of presentations of COVID-19 and postinfectious processes. Clinicians should constantly have a high level of suspicion for COVID-19.

The "Let's Talk!" Conference: A Culture-Specific Community Intervention for Asian and Asian American Student Mental Health.

Asian and Asian American students face culture-specific mental health risk factors, and the current study aims to examine whether a culture-specific community intervention in the form of a conference is an effective modality for psychoeducation in the Asian American community. Participants were assessed for reported changes in knowledge, attitudes, and behavior intentions related to mental health after attending the conference. A total of 118 conference participants filled out the survey. Participants reported changes in knowledge regarding mental health issues, generational differences, and the effects of culture. Participants also reported having a more open attitude towards mental health, having greater acceptance of mental health issues in themselves and others, and realizing that mental health issues are a community issue. Lastly, participants reported changes in behavior intentions such as communicating more with friends and family, engaging in perspective-taking, participating in advocacy and activism on mental health issues, and taking care of themselves and others.

Clinical outcomes in ovarian cancer patients receiving three versus more cycles of chemotherapy after neoadjuvant treatment and interval cytoreductive surgery.

OBJECTIVES: To compare clinical outcomes for stage IIIC and IV ovarian cancer patients receiving neoadjuvant chemotherapy and interval cytoreductive surgery followed by up to three versus more cycles of post-operative chemotherapy. METHODS: We conducted a multi-institution retrospective cohort study of patients treated from January 2005 to February 2016 with neoadjuvant platinum-based therapy followed by interval surgery and post-operative chemotherapy. The following were exclusion criteria: more than four cycles of neoadjuvant chemotherapy, bevacizumab with neoadjuvant chemotherapy, non-platinum therapy, prior chemotherapy, and elevated CA125 values after three post-operative chemotherapy cycles. Progression-free and overall survival and toxicity profiles were compared between groups receiving up to three cycles versus more that three cycles post-operatively. RESULTS: A total of 100 patients met inclusion criteria: 41 received up to three cycles and 59 received more than three cycles. The groups were similar in terms of age, body mass index, performance status, tumor histology, optimal cytoreduction rates, and median number of neoadjuvant chemotherapy cycles. Median progression-free survival was 14 vs 16.6 months in those receiving up to three cycles versus more than three cycles, respectively (HR 0.99, 95% CI 0.58 to 1.68, p=0.97). Similarly, median overall survival was not different at 47.1 vs 69.4 months, respectively (HR 1.96, 95% CI 0.87 to 4.42, p=0.10). There were no differences in grade 2 or higher chemotherapy-related toxicities. CONCLUSIONS: Extending post-operative chemotherapy beyond three cycles in patients receiving neoadjuvant chemotherapy and interval cytoreductive surgery with normalization of CA125 levels was not associated with improved survival or greater toxicity. Future study in a larger cohort is warranted to define optimal length of cytotoxic treatment.

Combination simvastatin and metformin synergistically inhibits endometrial cancer cell growth.

OBJECTIVE: Recent data show that simvastatin (SIM) and metformin (MET) have anti-proliferative effects in endometrial cancer cells. The combination (MET+SIM) inhibits tumor growth and metastasis in prostate cancer cells which possess similar molecular alterations to many early endometrial cancers. We tested the hypothesis that the anti-proliferative effects of MET+SIM in endometrial cancer cells would be greater than the effects of each agent alone. METHODS: RL95-2, HEC1B, and Ishikawa endometrial cancer cell lines were treated with MET and/or SIM. Growth inhibition was measured by MTS cell proliferation assays. Apoptosis was evaluated by caspase-3, Annexin V, and TUNEL assays and by apoptosis markers (BAX, Bcl-2, Bim) using western blot. Bim was silenced using Bim siRNA to confirm this apoptotic pathway. Treatment effects on the mTOR pathway were investigated by western blot using antibodies to phosphorylated (phospho)-AMPK and phospho-S6. RESULTS: MET+SIM synergistically inhibited growth in all three cell lines. The combination induced apoptosis as measured by TUNEL, Annexin V, and caspase-3 assays. Bim siRNA transfection abrogated this effect-silencing Bim in MET+SIM-treated RL95-2 cells rescued cell viability in MTS assays and reduced caspase-3 activity compared with control siRNA-transfected cells. Combination treatment upregulated phosphorylated AMPK and downregulated downstream phosphorylated S6, suggesting mTOR inhibition as a mechanism for these anti-proliferative effects. CONCLUSIONS: MET+SIM treatment synergistically inhibits endometrial cancer cell viability. This may be mediated by apoptosis and mTOR pathway inhibition. Our results provide preclinical evidence that the combination of these well-tolerated drugs may warrant further clinical investigation for endometrial cancer treatment.

Venous Thromboembolism in Patients Receiving Extended Pharmacologic Prophylaxis After Robotic Surgery for Endometrial Cancer.

OBJECTIVE: This study aims to determine the rate of postoperative venous thromboembolism (VTE) in endometrial cancer patients undergoing robotic hysterectomy with or without extended pharmacologic VTE prophylaxis. METHODS/MATERIALS: A retrospective chart review of women undergoing robotic hysterectomy with or without other procedures for endometrial cancer from January 2010 to February 2015 was conducted at 2 institutions. Charts were manually abstracted, and rates of VTE within 30 and 60 days after surgery were determined. Patients were then stratified by those who did and did not receive extended VTE prophylaxis. RESULTS: A total of 403 patients were included, of which 367 patients (91%) received extended pharmacologic prophylaxis and 36 patients (9%) did not. Low molecular weight heparin prescriptions ranged from 7 to 30 days. Patients receiving extended prophylaxis (EP) were older (63 ± 11 vs 57 ± 12; P = 0.004), more frequently underwent lymphadenectomy (67% vs 34%; P < 0.001), and had higher-grade tumors compared with patients not receiving EP. Overall 30-day and 60-day VTE rates were 0.7% and 1.2%, respectively. There were no significant differences in 30-day and 60-day VTE rates among patients that did and did not receive EP, although a trend toward lower VTE rates in the EP group was observed (30-day rates 0.5% vs 2.8% respectively, P = 0.25; 60-day rates 0.8% vs 5.6%, P = 0.07). CONCLUSIONS: In this study, 30-day and 60-day VTE rates after minimally invasive surgery for endometrial cancer were low. Rates were also similar to those of previous reports in this setting in which the majority of patients did not receive extended VTE prophylaxis. Given the consistent finding that postoperative VTE in this population is rare regardless of prophylaxis use and the variability in practice patterns for VTE prophylaxis, the development of best practice guidelines for EP use specific to this setting is warranted.

Enzymatic Evidence for a Revised Congocidine Biosynthetic Pathway.

Naturally produced pyrrolamides, such as congocidine, are nonribosomal peptides that bind to the minor groove of DNA. Efforts to delineate the biosynthetic machinery responsible for their assembly have mainly employed genetic methods, and the enzymes responsible for their biosynthesis remain largely uncharacterized. We report the biochemical characterization of four proteins involved in congocidine formation: the adenylation-thiolation (A-T) di-domain Cgc18(1-610), its MbtH-like partner SAMR0548, the AMP-binding enzyme Cgc3*, and the T domain Cgc19. We assayed the ATP-dependent activation of various commercially available and chemically synthesized compounds with Cgc18(1-610) and Cgc3*. We report the revised substrate specificities of Cgc18(1-610) and Cgc3*, and loading of 4-acetamidopyrrole-2-carboxylic acid onto Cgc19. Based on these biochemical studies, we suggest a revised congocidine biosynthetic pathway.

Recurrent cervical cancer isolated to the sigmoid colon: A case report.

Fused positron emission tomography and computed tomography scan showed a hypermetabolic lesion in the sigmoid colon, with no evidence of metastatic disease elsewhere.

The effects of exposure to general anesthesia in infancy on academic performance at age 12.

BACKGROUND: Recent evidence from juvenile animal models has shown that exposure to anesthetic drugs above threshold doses during a critical neurodevelopmental window causes widespread neuronal apoptosis, resulting in irreversible brain damage and subsequent learning difficulties. The relevance of this to human infants having general anesthesia for minor surgery is unknown. In this pilot observational cohort study, we sought to determine whether children exposed to general anesthesia for minor surgery during infancy exhibited differences in academic achievement at age 12 years, as evidenced by (1) lower aggregate scores in the Singapore standardized Primary School Leaving Examination (PSLE) and (2) formally diagnosed learning disability, compared with children who were never exposed to anesthesia or sedation. METHODS: We compared 100 full-term, apparently healthy children aged 12 years who were exposed to general anesthesia for minor surgery before age 1 at our institution with an age-matched cohort of 106 children who were never exposed to anesthesia or sedation. Parents of children completed a 20-minute telephone interview with questions regarding their children's medical history, school environment, and home environment. RESULTS: The difference in mean PSLE aggregate scores (3.0; 95% confidence interval [CI], -8.3 to 14.3) between exposed (197.0; 95% CI, 185.6-208.4) and control groups (194.0; 95% CI, 182.9-205.1) was not statistically significant (P = 0.603). The presence of formally diagnosed learning disability was 15% (15 of 100) in the exposed group compared with 3.77% (4 of 106) in the control group (P < 0.001). The odds ratio for a formal diagnosis of learning disability in those exposed to general anesthesia relative to controls was 4.5 (95% CI, 1.44-14.1). CONCLUSION: The odds of a formal diagnosis of learning disability by age 12 years in apparently healthy children exposed to general anesthesia for minor surgery during infancy were 4.5 times greater than their peers who had never been exposed to anesthesia. However, study precision was inadequate to detect a clinically relevant difference in PSLE scores.

Excess risk of Clostridium difficile infection in ovarian cancer is related to exposure to broad-spectrum antibiotics.

PURPOSE: The purpose of the study was to determine if a diagnosis of ovarian cancer is independently associated with an increased risk of Clostridium difficile infection (CDI). METHODS: The University HealthSystem Consortium database was queried to perform a retrospective cohort study of women with and without ovarian cancer who were diagnosed with CDI. Inpatients undergoing total hysterectomy from 2008 to 2012 were studied. Ovarian cancer patients were compared to non-ovarian cancer patients to evaluate relative risk (RR) of CDI. Adjustment was made for known or suspected CDI risk factors to determine RR of CDI independent of these variables. RESULTS: In this study, 115,203 patients were included. CDI was reported in 0.80 % of ovarian cancer patients and in 0.31 % of non-ovarian cancer patients (RR = 2.50; 95 % confidence interval (CI) = 2.02 to 3.35). Stratification by age, presence of other comorbidities, or administration of antineoplastic drugs did not significantly modify the elevated risk associated with ovarian cancer. Significantly increased risk in ovarian cancer patients was no longer observed after controlling for broad-spectrum antibiotic administration (RR = 1.28, 95 % CI = 0.39 to 4.13). Compared to non-ovarian cancer patients, ovarian cancer patients were more frequently treated with broad-spectrum antibiotics, had a 39 % longer mean duration of therapy, and had 2.5-fold greater mean total exposure to broad-spectrum antibiotics. CONCLUSIONS: After adjustment for antibiotic use, ovarian cancer patients are not at excess risk of CDI. Additional studies are needed to understand the patterns of broad-spectrum antibiotic prescription for ovarian cancer patients leading to increased exposure. If feasible, reduction of this exposure may decrease morbidity in this population.

Inhibition of focal adhesion kinase (FAK) activity prevents anchorage-independent ovarian carcinoma cell growth and tumor progression.

Recurrence and spread of ovarian cancer is the 5th leading cause of death for women in the United States. Focal adhesion kinase (FAK) is a cytoplasmic protein-tyrosine kinase located on chromosome 8q24.3 (gene is Ptk2), a site commonly amplified in serous ovarian cancer. Elevated FAK mRNA levels in serous ovarian carcinoma are associated with decreased (logrank P = 0.0007, hazard ratio 1.43) patient overall survival, but how FAK functions in tumor progression remains undefined. We have isolated aggressive ovarian carcinoma cells termed ID8-IP after intraperitoneal (IP) growth of murine ID8 cells in C57Bl6 mice. Upon orthotopic implantation within the peri-ovarian bursa space, ID8-IP cells exhibit greater tumor growth, local and distant metastasis, and elevated numbers of ascites-associated cells compared to parental ID8 cells. ID8-IP cells exhibit enhanced growth under non-adherent conditions with elevated FAK and c-Src tyrosine kinase activation compared to parental ID8 cells. In vitro, the small molecule FAK inhibitor (Pfizer, PF562,271, PF-271) at 0.1 uM selectively prevented anchorage-independent ID8-IP cell growth with the inhibition of FAK tyrosine (Y)397 but not c-Src Y416 phosphorylation. Oral PF-271 administration (30 mg/kg, twice daily) blocked FAK but not c-Src tyrosine phosphorylation in ID8-IP tumors. This was associated with decreased tumor size, prevention of peritoneal metastasis, reduced tumor-associated endothelial cell number, and increased tumor cell-associated apoptosis. FAK knockdown and re-expression assays showed that FAK activity selectively promoted anchorage-independent ID8-IP cell survival. These results support the continued evaluation of FAK inhibitors as a promising clinical treatment for ovarian cancer.

Francisella tularensis: possible agent in bioterrorism.

Francisella tularensis, the causative agent of tularemia, is a highly infectious gram-negative coccobacillus. Due to its high infectivity it is of major concern to public health officials as a possible biological weapon. Although accidental exposure can occur through arthropod bites, handling infected animals, or breathing in aerosols, cases are usually isolated and contained. In the event of an intentional exposure such as in a bioterrorist attack, inhalation of aerosols can result in devastating consequences with much causality. Although a vaccine is available, sufficient quantities may not be readily accessible in an actual attack. Therefore, it is very important for both medical professionals and public health officials to be prepared to contain and control the situation should it actually occur.
