Abstract
Ovarian cancer is the most common cause of death due to gynecologic malignancies, with more than 70% of patients presenting with advanced stage disease at the time of diagnosis. The extent and distribution of tumor guide primary treatment selection and clinical management. While primary cytoreductive surgery with complete tumor resection improves survival, patients with extensive peritoneal disease may benefit from neoadjuvant chemotherapy first to reduce tumor burden followed by interval cytoreductive surgery. Imaging plays an essential role in triaging patients including selecting patients who may benefit from neoadjuvant chemotherapy before cytoreductive surgery. Interestingly, there are no universally established criteria to predict resectability and local practices depend on local guidelines and surgeon preferences. Nevertheless, certain anatomical tumor locations are known to be difficult to resect and are associated with suboptimal cytoreduction or require special surgical considerations. This review discusses the recent advances in the initial management of patients with ovarian cancer, a practical approach to the assessment and communication of peritoneal metastases locations on CT and MRI. It also explores recent advances in genomics profiling and radiomics that may influence the initial management of these patients.

Abstract
INTRODUCTION In gynecologic patients, few studies describe the accuracy of the American College of Surgeons-National Surgical Quality Improvement Project (ACS-NSQIP) pre-operative risk calculator for women undergoing surgery for ovarian cancer. OBJECTIVE To determine whether the ACS-NSQIP risk calculator accurately predicts post-operative complications and length of stay in patients undergoing interval debulking surgery for advanced stage epithelial ovarian cancer. METHODS For this multi-institutional retrospective cohort study, pre-operative risk factors, post-operative complication rates, and Current Procedural Terminology codes were abstracted from records of patients with ovarian cancer managed with open interval debulking surgery from January 2010 to July 2015. A power calculation was done to estimate the minimum number of complications needed to evaluate the accuracy of the ACS-NSQIP risk calculator. Predicted risk compared with observed risk was calculated using logistic regression. The predictive accuracy of the ACS-NSQIP risk calculator in estimating post-operative complications or length of stay was assessed using c-statistics and Briar scores. Complications with a c-statistic of >0.70 and Brier score of <0.01 were considered to have high discriminative ability. RESULTS A total of 261 patients underwent interval debulking surgery, encompassing 21 unique Current Procedural Terminology codes. Readmission (n=25), surgical site infection (n=35), urinary tract infection (n=12), and serious post-operative complications (n=57) met the minimum event threshold (n>10). All predicted complication rates fell within the IQR of the observed incidence rates. However, the ACS-NSQIP calculator demonstrated neither discriminative ability nor accuracy for any post-operative complications based on c-statistics and Brier scores. The calculator accurately predicted length of stay within 1 day for only 32% of patients and could not accurately predict which patients were likely to have a prolonged length of stay (c-statistic=0.65). CONCLUSION Among patients undergoing interval debulking surgery, the ACS-NSQIP did not accurately discriminate which patients were at increased risk of complications or extended length of stay. The risk calculator should be considered to have limited utility in informing pre-operative counseling or surgical planning.

Abstract
OBJECTIVE To evaluate the impact of size and distribution of residual disease after interval debulking surgery on the timing and patterns of recurrence for patients with advanced-stage epithelial ovarian cancer. METHODS Patient demographics and data on disease treatment/recurrence were collected from medical records of patients with stage IIIC/IV epithelial ovarian cancer who were managed with neoadjuvant chemotherapy/interval debulking surgery between January 2010 and December 2014. Among patients without complete surgical resection but with ≤1 cm of residual disease, the number of anatomic sites (<1 cm single anatomic location vs <1 cm multiple anatomic locations) was used to describe the size and distribution of residual disease. RESULTS: A total of 224 patients were included. Of these, 70.5% (n=158) had a complete surgical resection, 12.5% (n=28) had <1 cm single anatomic location, and 17.0% (n=38) had <1 cm multiple anatomic locations. Two-year progression-free survival for complete surgical resection, <1 cm single anatomic location, and <1 cm multiple anatomic locations was 22.2%, 17.9% and 7%, respectively (p=0.007). Size and distribution of residual disease after interval debulking surgery did not affect location of recurrence and most patients had recurrence at multiple sites (complete surgical resection: 64.7%, <1 cm single anatomic location: 55.6%, and <1 cm multiple anatomic locations: 71.4%). Controlling for additional factors that may influence platinum resistance and surgical complexity, the rate of platinum-resistant recurrence was similar for patients with complete surgical resection and <1 cm single anatomic location (OR=1.07, 95% CI 0.40 to 2.86; p=0.888), but women with <1 cm multiple anatomic locations had an increased risk of platinum resistance (OR=3.09, 95% CI 1.41 to 6.78 p=0.005). CONCLUSIONS Despite current classification as 'optimal,' <1 cm multiple anatomic location at the time of interval debulking surgery is associated with a shorter progression-free survival and increased risk of platinum resistance.

Abstract
OBJECTIVES Ovarian cancer patients with miliary disease have the lowest rates of complete surgical resection and poorest survival. Adjunct surgical techniques may potentially increase rates of complete surgical resection. No studies have evaluated the use of these techniques in primary debulking surgery for ovarian cancer patients with miliary disease. The aim of this study was to examine the use of adjunct surgical techniques during primary debulking surgery for patients with advanced epithelial ovarian, fallopian tube, and primary peritoneal cancer with miliary disease. METHODS Medical records of patients with International Federation of Gynecology and Obstetrics (FIGO) stages IIIC-IVB epithelial ovarian, fallopian tube, or primary peritoneal cancer with miliary disease undergoing primary debulking surgery from January 2010 to December 2014 were reviewed. Adjunct surgical techniques were defined as ultrasonic surgical aspiration, argon enhanced electrocautery, thermal plasma energy, and traditional electrocautery ablation. Patients undergoing surgery with and without these devices were compared with respect to demographics, operative characteristics, postoperative complications, residual disease, progression free survival and overall survival. RESULTS A total of 135 patients with miliary disease underwent primary debulking surgery, of which 30 (22.2%) patients used adjunct surgical techniques. The most common devices were ultrasonic surgical aspiration (40%) and argon enhanced electrocautery (36.7%). The most common sites of use were diaphragm (63.3%), pelvic peritoneum (30%), bowel mesentery (20%), and large bowel serosa (20%). There were no differences in age, stage, primary site, histology, operative time, surgical complexity, or postoperative complications for patients operated on with or without these devices. Volume of residual disease was similar (0.1-1 cm: 60% with adjunct techniques versus 68.6% without; complete surgical resection: 16.7% with adjunct techniques versus 13.3% without; p=0.67). For patients with ≤1 cm residual disease, median progression free survival (15 versus 15 months, p=0.65) and median overall survival (40 versus 55 months, p=0.38) were also similar. CONCLUSION Adjunct surgical techniques may be incorporated during primary debulking surgery for patients with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer with miliary disease; however, these do not improve the rate of optimal cytoreduction.

Abstract
OBJECTIVE There are limited data on clinical outcomes of patients with advanced-stage epithelial ovarian cancer who require ostomy formation at the time of either primary cytoreductive surgery or interval cytoreductive surgery. The objective of this study was to evaluate patients undergoing bowel surgery and ostomy formation after primary or interval surgery. METHODS Patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV epithelial ovarian cancer who underwent cytoreductive surgery between January 2010 and December 2014 were identified retrospectively. Patients with non-epithelial histology, low-grade serous histology or incomplete medical records were excluded. Demographic and clinical data were collected and analyzed. Age, stage, co-morbidity index, pre-operative CA125, pre-operative albumin, and Aletti surgical complexity score were included in a multivariable logistic regression model to assess independent associations with ostomy formation. RESULTS A total of 554 patients were included in the study. Of these, 261 (47%) underwent primary cytoreduction and 293 (53%) underwent interval cytoreduction. Patients undergoing primary surgery were more likely to undergo bowel resection, compared with interval surgery patients (37.2% vs 14%, p<0.001). Of the 139 (25.1%) patients who underwent bowel surgery, 25 (18%) underwent ostomy formation (11 ileostomies and 14 colostomies). Rates of ostomy formation were similar between the groups (6.1% primary vs 3.1% interval, p=0.10). Patients undergoing ostomy formation were more likely to have longer mean operative time (335 vs 229 min, p<0.001) and undergo small and large bowel resections at the time of cytoreductive surgery (44% vs 14%, p<0.001). Multivariate analysis revealed that a high surgical complexity score was associated with ostomy formation. Of the patients who underwent ostomy formation, 13 (43.3%) underwent stoma reversal including 11 ileostomies and two colostomies. Median time to ostomy reversal was 7 months. CONCLUSION Bowel surgery is more common among patients undergoing primary surgery as compared with interval surgery, but this does not result in an increased risk of ostomy formation.

Abstract
OBJECTIVE To evaluate the impact of insurance status on the stage of cervical cancer diagnosed and treated at a tertiary care center in Massachusetts and review the preceding screening history. METHODS An IRB approved retrospective cohort study was conducted of patients with a diagnosis of cervical cancer treated at Brigham and Women's Hospital (BWH) between January 2011 and June 2016. Clinical and demographic data was extracted from the longitudinal medical record. Statistical analysis was performed using SAS. RESULTS 117 cases of cervical cancer met the inclusion criteria during the study period. Most patients (76%) were diagnosed with stage I disease. On univariate analysis, compared to patients with private insurance, patients with public insurance or no documented insurance presented at older ages, were more likely to be non-white races, and present with advanced stage disease. In an adjusted model, the risk of being diagnosed with advanced stage disease persisted among women with public or no documented insurance, adjusted odds ratio (aOR) 4.13 (1.37-12.45). There was no difference in screening history among women with private vs. public insurance, p = 0.30. CONCLUSIONS Despite access to insurance, patients with public issued insurance had an increased risk of presenting with advanced stage cervical cancer in this cohort. These data suggest that additional barriers to screening and prevention may exist and are important for future investigation.

Abstract
The cheetah (Acinonyx jubatus) has been considered a paradigm for disease vulnerability due to loss of genetic diversity. This species monomorphism has been suspected to be the basis for their general poor health and dwindling populations in captivity. North American and South African captive populations have high prevalences of hepatic veno-occlusive disease, glomerulosclerosis, gastritis, and systemic amyloidosis, diseases that are rare in other species. Unusually severe inflammatory reactions to common infectious agents have also been documented in captive cheetahs. The current study compared disease prevalences in free-ranging Namibian cheetahs with those in two captive populations of similar ages. The occurrence of diseases in the free-ranging population was determined from 49 necropsies and 27 gastric biopsies obtained between 1986 and 2003 and compared with prevalences in 147 North American and 80 South African captive cheetahs. Except for two cheetahs, the free-ranging population was in robust health with only mild lesions present, in contrast with significantly higher prevalences in the captive populations. Despite widespread heavy Helicobacter colonization in wild cheetahs, only 3% of the free-ranging population had moderate to severe gastritis, in contrast with 64% of captive cheetahs. No severe inflammatory reactions to viral infections were detected in the free-ranging animals. Because free-ranging Namibian cheetahs are as genetically impoverished as captive cheetahs, these findings caution against attributing loss of fitness solely to genetic factors and attest to the fundamental importance of extrinsic factors in wildlife health.

Abstract
When rhinoceros species that are browsers in the wild are fed in captivity they become iron overloaded. Presumably, their iron-absorptive mechanisms have evolved to become highly efficient. In humans, mutations of the HFE gene cause increased iron absorption. To determine whether the HFE gene of rhinoceroses has undergone mutation as an adaptive mechanism to improve iron absorption from iron-poor diets, we have sequenced the entire coding region of the HFE genes of four species of rhinoceros. Two of these were browsing species and two were grazing species. Although the HFE gene has been well preserved across species, numerous nucleotide differences were found between rhinoceros and human or mouse, some of which changed deduced amino acids. Of these mutations, only one found in the black rhinoceros appears to be a viable candidate mutation that might adversely affect HFE function. This mutation, S88T, is in a highly conserved region that is involved in the interaction between transferrin receptor and HFE.

Abstract
While the diet of the platypus
(Ornithorhynchus anatinus) is known to include a wide
range of benthic macro-invertebrates, little is known about how the animals
distribute their feeding behaviour along a waterway. This radio-tracking study
aimed to determine whether the spatial distribution of platypus foraging
activity varied in relation to habitat attributes and/or the amount of
food present along a southern Victorian stream. Five
O. anatinus were tracked nocturnally for a total of
nearly 95 h in March and April 2000. Attributes of the channel and bank were
described both in the area used by the animals and adjoining unused sections
of stream, and macro-invertebrates were sampled quantitatively in six
substrates that varied in abundance in the used and unused areas. Eleven
habitat variables showed a significant positive relationship with the
occurrence of platypus activity (including the number of medium and large
Eucalyptus, Acacia and
Populus trees growing along the bank; presence of
gravel, pebbles, cobbles, large rocks and coarse particulate organic matter in
the channel substrate; amount of riffle habitat; amount of large woody debris
in the channel; and amount of undercut banks). Six habitat variables showed a
significant negative relationship with platypus activity (including the number
of medium and large Salix trees growing along the bank;
the presence of silt, solid clay and Salix roots in the
channel substrate; the amount of pool habitat; and the maximum channel depth).
Substrates that were relatively abundant in the area used by
O. anatinus (gravel/pebbles,
Eucalyptus litter, Populus litter)
did not consistently support more macro-invertebrates than substrates that
dominated the unused area (silt, Salix roots,
Salix litter). This may reflect the fact that the
platypus population was not food-limited (and hence not under pressure to
optimise foraging) at the time of the study, that platypus feeding patterns
were influenced by habitat features that were not considered in relation to
invertebrate abundance, or that the choice of foraging areas by
O. anatinus may be influenced by factors other than the
total abundance of food items, e.g. the nutritional quality and/or
accessibility of prey.

Abstract
The National Zoological Park has maintained a breeding colony of Matschie's tree kangaroos (Dendrolagus matschiei) since 1975 with a documented history and continued prevalence of Mycobacterium avium complex (MAC) infections. No evidence of immunosuppressive retrovirus infections or loss of heterozygosity that may have led to an immune dysfunction in these animals was found. Isolates of MAC organisms from affected tree kangaroos and from their environment had no common restriction fragment DNA types. Cellular immune reactivity in apparently healthy tree kangaroos was 3- to 6-fold lower than in humans and other marsupial and eutherian mammals, as determined by lymphocyte proliferative assays. Thus, while MAC infections are typically opportunistic in humans and other mammals, tree kangaroos commonly develop primary progressive disease with MAC from random sources. Comparative information derived from this study should benefit both the endangered tree kangaroo and humans with immunosuppressive disorders that lead to mycobacterial infections.

Abstract
An in vitro cytotoxicity model that uses an immortalized human microvascular endothelial cell line (HMEC-1) differentiates Brazilian purpuric fever (BPF)-associated Haemophilus influenzae biogroup aegyptius (HAE) strains from non-BPF-associated HAE strains. Toxic strains produced a characteristic HMEC-1 phenotype at an MOI of < 1 bacterium/1000 tissue culture cells (TCC). Nontoxic strains required MOIs of > 1000 bacteria/TCC to produce an observable effect. The cytotoxic phenotype was characterized by the presence of large clumps of HMEC-1 cells, which detached from the monolayer within 48 h of inoculation by HAE cells. The cytotoxic phenotype was observed with 100% of BPF-associated HAE (40/40) and 14% of non-BPF-associated HAE (8/57; P < .001). The ability to study a BPF-associated phenotype in vitro using human microvascular cells should enhance our knowledge of BPF pathogenesis.

Abstract
A repetitive genomic DNA clone (B12-2) that specifically hybridizes to Pneumocystis carinii DNA has been identified. No cross-hybridization to genomic DNA prepared from bacteria, other fungi, protozoa, or mammals was observed. Clone B12-2 is multiply represented in the P. carinii genome. By direct hybridization to DNA prepared from the lungs of immunosuppressed rats, the probe can detect the equivalent of fewer than 1,000 P. carinii organisms. A hybridization assay employing clone B12-2 has been developed to quantitate organism load in the rat model for P. carinii. Application of the assay to track the accumulation of organisms during the immunosuppression regimen as well as to monitor the efficacy of two drug therapies used clinically for the treatment of P. carinii pneumonia is described here. The clone B12-2 hybridization assay for the determination of P. carinii organism load possesses several advantageous features and thus should serve to complement conventional staining and immunohistochemical methods.

Abstract
Lack of genetic variability and apparent susceptibility of cheetahs (Acinonyx jubatus jubatus) to coronavirus infection has lead to speculation that this species may have immune system deficits. To establish a foundation for evaluation of the immune function, cheetah peripheral blood mononuclear cells (PBM) were stimulated by a panel of six mitogens, and responses compared with those of domestic cat PBM. Individual responses in both species were variable, but evenly distributed throughout the range of stimulation for each mitogen. Proliferation by PBM from domestic cats occurred within the same range as that of the cheetahs. However, a significantly lower response to peanut agglutinin (PNA) was observed with domestic cat PBM. Although responses varied between animals, certain individual cheetahs were consistent low responders. The decreased values could not be explained by lack of IL-2 responsiveness since exogenous IL-2 significantly enhanced mitogen-stimulated proliferation in 11 of 12 cheetahs tested. The phenotypic distribution of domestic cat and cheetah lymphocyte subpopulations was similar as assessed by immunofluorescence staining for surface immunoglobulin (sIg) and cytotoxic T (Tc) cells (using a specific monoclonal antibody, FT2). Values for B cells (31.2% sIg+) and Tc (28.7% FT2+) were slightly higher in domestic cats as compared with cheetah PBM (13.3% sIg+; 19.0% FT2+). Even though no species-specific deficits were detected, a significant negative correlation between PHA-stimulated proliferation and percent FT2+ (Tc) cheetah cells was observed. This indicates that proliferation can be used indirectly to assess relative numbers of functional T helper cells in cheetahs. Our studies suggest that these aspects of the cheetah's immune system are comparable with the domestic cat, and establish a basis for in vitro assays evaluating antigen-specific responses.

Abstract
Callitrichid hepatitis (CH) is a newly recognized, acute, fatal, epizootic disease of New World primates in the family Callitrichidae. Since 1980, 12 outbreaks of CH have occurred in US zoos, involving several callitrichid species including the endangered golden lion tamarin (Leontopithecus rosalia). CH was experimentally transmitted to common marmosets via a bacteria-free filtrate of liver from a naturally infected tamarin. All three inoculated marmosets developed an acute fatal disease with the characteristic clinical and histopathologic findings of CH. Human hepatotropic viruses that can infect the livers of callitrichids were not detected serologically in any of the experimentally infected marmosets. Enveloped viruslike particles 85-105 nm in diameter were observed in the rough endoplasmic reticulum and Golgi complex of hepatocytes from both naturally infected and experimentally inoculated animals. An immunoblot assay was developed using sera from tamarins exposed to natural outbreaks of CH and liver extracts from experimentally infected or control marmosets. A new CH-specific antigen was detected in the livers of naturally infected and experimentally inoculated marmosets but not controls. These results suggest that the etiologic agent of callitrichid hepatitis is a new primate hepatitis virus.

Abstract
A total of 157 dogs with lymphosarcoma were available for study; 67 were treated. All of the treated dogs were given 4 drug combinations and 20 of them also were given autogenous vaccine. Sixty (90%) of the dogs treated with multiple drugs improved clinically. Of the dogs with clinical improvement, 48 (80%) had either complete or partial remission; of these, 32 (67%) had complete remission. Clinical staging proved useful in increasing the accuracy of prognosis, whereby dogs in less advanced stages of disease responded better to therapy, with a higher percentage of complete clinical remissions and longer survival. The mean survival time of the 47 dogs treated with drugs alone was 138 days, which compared with a mean survival time of 30 days for 34 nontreated dogs. Dogs subjected to chemotherapy and immunotherapy had a mean survival time of 341 days. Dogs in complete remission at time of vaccination survived significantly (P less than 0.01) longer than did dogs treated with drugs and vaccinated while not incomplete remission.
