RESUMO
Long-term monitoring enables scientists and managers to track changes in the temporal and spatial distributions of fishes. Given the anthropogenic stressors affecting marine ecosystem health, there is a critical need for robust, comprehensive fish monitoring programs. Citizen science can serve as a meaningful, cost-effective strategy to survey fish communities. We compared data from 13,000 surveys collected over 21 years (1998-2019) by Reef Environmental Education Foundation (REEF) volunteer divers to a published compilation of Salish Sea ichthyofauna collected using an assortment of methods. Volunteer divers observed 138 of 261 recognized species in the Salish Sea, expanded the range of 18 species into additional Salish Sea sub-basins, and identified one species novel to the Salish Sea (Gibbonsia metzi - Striped Kelpfish). To identify Salish Sea fish species that are most suitable to be monitored by underwater visual census and to evaluate confidence in in situ identification, we developed a categorization system based on the likelihood of recreational divers and snorkelers encountering a given species, and on whether identification required a specimen in hand or could be classified to species visually (with or without a high-quality photograph). REEF divers encountered 62% (138 of 223) of the visually detectable species occurring in the region and 85% (102 of 120) of species most likely to be observed by recreational divers. Our findings show that citizen scientists provide valuable monitoring data for over half of the 261 marine and anadromous fish species known to occupy the Salish Sea, many of which are not routinely monitored otherwise.

INTRODUCTION: Carboplatin hypersensitivity reactions have been reported to occur in up to 16% of patients with gynecologic cancers. Several predisposing factors have been suggested including presence of BRCA1/2 mutation, however, contribution of these mutations to reaction development has not been extensively studied. The purpose of this study was to determine if there is an association between BRCA1/2 mutation status and the development of carboplatin hypersensitivity reactions.Methodology: Eligible patients were women aged 18 years or older with a diagnosis of ovarian, fallopian tube, uterine, endometrial, or primary peritoneal cancer who attempted to receive at least one dose of carboplatin. The primary outcome was the effect of BRCA1/2 status on the development of carboplatin hypersensitivity reactions with regard to: reaction frequency, timing, and severity. Secondary outcomes included identification of additional risk factors that may help identify predisposition to carboplatin hypersensitivity reaction. RESULTS: A total of 44 patients were included in this study. Five patients (38%) in the reaction group and 4 patients (31%) in the no reaction group had a documented mutation in one or both BRCA genes (p = 1.00). No significant differences were found in terms of reaction severity or symptoms, and timing of reaction after dose administration. Incidence of thyroid disorder was significantly higher among patients who experienced a hypersensitivity reaction (1 (4%) vs 10 (45%); p = 0.004). CONCLUSION: BRCA mutation status was not associated with an increased risk of carboplatin hypersensitivity in our patient population. Further investigation into thyroid dysfunction as a risk factor for reaction development is warranted.

Mesonephric adenocarcinoma is a rare tumor, accounting for <1% of cervical cancers. Well-differentiated mesonephric adenocarcinoma can be difficult to distinguish from diffuse mesonephric hyperplasia. Herein, we report a case of well-differentiated mesonephric adenocarcinoma with an FGFR2 mutation not previously reported in the literature. Nonselective tyrosine kinase inhibitors or FGFR2 inhibitors may represent options for targeted therapy.

Background: To meet increased community and regional needs for quality services, our hospital system concluded that its established surgical oncology program-consisting of gynecologic oncology (4 physicians), surgical oncology (2 physicians), and otolaryngologic oncology (2 physicians)-would be best served by the transition of the comprehensive surgical oncology program to a new oncology-naive hospital. We describe the overall strategy and approach involved with this move, its implementation, operating room efficiency results, and physician satisfaction associated with the relocation. Methods: The purpose of the systematic plan for relocation, which was developed and refined during the 2 years preceding the move, was to facilitate a collective awareness and understanding of important patient-centered concepts and essential workflow. All parties involved in direct patient cancer care participated in multiple workgroups to successfully transition the surgical oncology practice. Following the transition to the oncology-naive hospital, components of the operative cases and surgical data were prospectively collected for the initial 6 weeks and compared to retrospective data from the last 8 weeks at the established hospital. The surgical day for each surgeon was deconstructed, and measured variables included total surgical cases, total surgical hours, surgical minutes per case, total anesthesia hours, first case on-time surgical starts, surgical stretcher wheels out to surgical stretcher wheels in, surgical stretcher wheels out to next case start, case end to postanesthesia care unit (PACU), and case end to case start. Results: Five hundred twenty-nine surgical cases encompassing 1,076 anesthesia hours and 710 surgical hours were completed during the 14-week evaluation period. The gynecologic oncologists completed the majority of surgical procedures in both settings. The percentage of first case on-time surgical starts initially decreased during the 6-week interval at the oncology-naive hospital, but interval subset analysis suggested a return to the pre-move norm. Surgical stretcher wheels out to surgical stretcher wheels in had a wide range (9 minutes to 305 minutes) for all surgical sections, but no statistically significant difference was seen overall or for any surgical section. Case end to PACU significantly increased for gynecologic oncology but not for surgical oncology or otolaryngologic oncology. Overall case end to case start times decreased nonsignificantly (63.7 ± 3.1 mean minutes vs 60.3 ± 1.7 mean minutes) following the move. A physician survey found that physicians' expectations were met in terms of the move occurring smoothly without major issues, surgical scheduling and accommodation, anesthesia services, and surgical personnel. Physicians indicated less satisfaction with quality and availability of instrumentation. Conclusion: The transfer of established surgical oncology services to an oncology-naive hospital was associated with early surgeon and operating room staff support, as well as process and programmatic alignment among stakeholders. The success of this transition required transparency, open and honest communication, and problem solving at all levels. The move of a surgical oncology program to an oncology-naive hospital was deemed successful without deterioration of time-related variables associated with operating room efficiency and physician satisfaction. The breakdown and analysis of key components of the surgical day offered additional opportunities for quality improvement in operating room efficiency.
RESUMO
Optimal healthcare blends timeless doctor-patient values with state-of-the-art medical knowledge. The physician's role varies from delivering therapies to guiding patients through the healthcare maze to their best decisions. Breast care should not be parceling out of anatomic parts, as if biological relationships do not exist. Instead, it should stem from an understanding of the "total woman"--biological and otherwise--and how important that unity is for quality of life, even when confronting breast cancer. Breast fellowships for gynecologic and general surgeons create superior clinicians and better patient advocates -essential in advancing women-centric care and healthcare leadership.

Pacific Ocean rockfishes (genus Sebastes) exhibit extreme variation in life span, with some species being among the most long-lived extant vertebrates. We de novo assembled the genomes of 88 rockfish species and from these identified repeated signatures of positive selection in DNA repair pathways in long-lived taxa and 137 longevity-associated genes with direct effects on life span through insulin signaling and with pleiotropic effects through size and environmental adaptations. A genome-wide screen of structural variation reveals copy number expansions in the immune modulatory butyrophilin gene family in long-lived species. The evolution of different rockfish life histories is coupled to genetic diversity and reshapes the mutational spectrum driving segregating CpGâTpG variants in long-lived species. These analyses highlight the genetic innovations that underlie life history trait adaptations and, in turn, how they shape genomic diversity.

BACKGROUND: The teleost order Lophiiformes, commonly known as the anglerfishes, contains a diverse array of marine fishes, ranging from benthic shallow-water dwellers to highly modified deep-sea midwater species. They comprise 321 living species placed in 68 genera, 18 families and 5 suborders, but approximately half of the species diversity is occupied by deep-sea ceratioids distributed among 11 families. The evolutionary origins of such remarkable habitat and species diversity, however, remain elusive because of the lack of fresh material for a majority of the deep-sea ceratioids and incompleteness of the fossil record across all of the Lophiiformes. To obtain a comprehensive picture of the phylogeny and evolutionary history of the anglerfishes, we assembled whole mitochondrial genome (mitogenome) sequences from 39 lophiiforms (33 newly determined during this study) representing all five suborders and 17 of the 18 families. Sequences of 77 higher teleosts including the 39 lophiiform sequences were unambiguously aligned and subjected to phylogenetic analysis and divergence time estimation. RESULTS: Partitioned maximum likelihood analysis confidently recovered monophyly for all of the higher taxa (including the order itself) with the exception of the Thaumatichthyidae (Lasiognathus was deeply nested within the Oneirodidae). The mitogenomic trees strongly support the most basal and an apical position of the Lophioidei and a clade comprising Chaunacoidei + Ceratioidei, respectively, although alternative phylogenetic positions of the remaining two suborders (Antennarioidei and Ogcocephaloidei) with respect to the above two lineages are statistically indistinguishable. While morphology-based intra-subordinal relationships for relatively shallow, benthic dwellers (Lophioidei, Antennarioidei, Ogcocephaloidei, Chaunacoidei) are either congruent with or statistically indistinguishable from the present mitogenomic tree, those of the principally deep-sea midwater dwellers (Ceratioidei) cannot be reconciled with the molecular phylogeny. A relaxed molecular-clock Bayesian analysis of the divergence times suggests that all of the subordinal diversifications have occurred during a relatively short time period between 100 and 130 Myr ago (early to mid Cretaceous). CONCLUSIONS: The mitogenomic analyses revealed previously unappreciated phylogenetic relationships among the lophiiform suborders and ceratioid familes. Although the latter relationships cannot be reconciled with the earlier hypotheses based on morphology, we found that simple exclusion of the reductive or simplified characters can alleviate some of the conflict. The acquisition of novel features, such as male dwarfism, bioluminescent lures, and unique reproductive modes allowed the deep-sea ceratioids to diversify rapidly in a largely unexploited, food-poor bathypelagic zone (200-2000 m depth) relative to the other lophiiforms occurring in shallow coastal areas.

OBJECTIVE: To describe and evaluate the technique and the clinical outcome of a new modality for the treatment of women with persistent or recurrent pelvic malignancies utilizing surgically (laparotomy or laparoscopic) guided high dose rate (HDR) catheters to complete high dose rate interstitial irradiation therapy (LG-HDRT). METHODS: Between 6/2000 and 6/2004, 14 women with histologic evidence of postradiation persistent (3 patients) or recurrent (11 patients) pelvic disease underwent LG-HDRT. Five patients (36%) received treatment for a 2nd, 3rd or 4th recurrence. Preoperative clinical and radiologic evaluation to exclude evidence of extrapelvic disease was routine. Initial intraoperative evaluation included intraabdominal inspection and or biopsy to determine the extent of disease. A two "team" approach was used to place the 100 cm Teflon after loading HDR catheters. Each catheter had its open ends closed with bone wax prior to placement. Using a 14 gauge intravenous catheter as a guide, each HDR catheter was individually placed transvaginally. The tumor bed (treatment volume) was marked circumferentially with clips to facilitate treatment planning. Dosimetry was typically completed on the day of surgery and HDR therapy was started within the initial 24 postoperative hours. The catheters were removed transvaginally, without anesthesia following completion of therapy. RESULTS: Mean patient age was 63.1 years and weight was 138.2 lb. Squamous cell cancer of the vagina or cervix was the most common (64%) diagnosis. The mean time from initial diagnosis to LG-HDRT was 67.9 months. The procedure was completed laparoscopically in 71% of patients, with 4 patients requiring laparotomy (3 conversions from laparoscopy). The mean duration of surgery was 94.9 min and the mean hospital stay was 4.8 days. Only 2 patients (14%) were discharged prior to the completion of therapy. The mean number of catheters placed was 6.1 and the mean dose delivered was 20 Gy over a mean of 5 fractions. There were no major intraoperative complications. Postradiation complications were limited to DVT (1), bladder bleeding (1), =grade 2 gastrointestinal disturbances (3) and vulvovaginal desquamation (1). Overall posttreatment survival (mean 20.75 months) has been excellent with only 2 local recurrences and one patient dead of disease. CONCLUSION: The efficacy of this treatment technique as demonstrated by the superb rate of local control (86%) and mean overall survival of 20.75 months compares favorably with other radiation or surgical treatment modalities in this population. Combined with the relative absence of morbidity, even when treating women following multiple recurrences suggests that LG-HDRT a viable treatment option for many women with local, postradiation persistent or recurrent pelvic cancer.

UNLABELLED: The physical properties of Poly(L-lactide/glycolide) indicate that the suture retains approximately 80% of its original strength at 3 months and 60% of its original strength at 6 months. This new long-term synthetic absorbable suture offers postoperative fascial strength for an extended period when compared to other available absorbables. Importantly, many women with gynecologic cancer will undergo radiation therapy during this interval. This report is intended to evaluate the effects of ionizing radiation on this suture. METHODS: One lot (op strands) of size 1 PLG suture was used. Ten (10) strands were used for baseline study of out of package tensile strength. Eighty (80) strands were placed in a buffer solution (pH approximately 9.0) and incubated in an in vitro water bath approximately 48 h at 55 degrees C to simulate 4 weeks in vitro residence time. Following this in vitro hydrolysis 20 strands were tested. Sixty strands were placed beneath a piece of fresh full thickness porcine skin and subcutaneous tissue and exposed to 3, 30, and 70 Gy. All samples were evaluated for breaking strength and elongation-at-break using an Instron tensiometer. RESULTS: Analysis of variance performed at the different exposure level revealed no significant effect on tensile properties (p>0.1). CONCLUSION: The tensile properties of PLG suture are not adversely affected by ionizing radiation. This long-term absorbable suture is an alternative for fascial closure when extended periods of support are necessary in patients destined to receive therapeutic ionizing radiation.

OBJECTIVES: To evaluate the activity and toxicity of danazol in advanced, recurrent, or persistent endometrial carcinoma. METHODS: Eligible patients with advanced, recurrent, or persistent endometrial carcinoma not amenable to curative therapy were treated with danazol at a dose of 100 mg four times per day until disease progression or toxicity necessitated discontinuation. Eligibility criteria included the presence of measurable disease and no prior chemotherapy. Immunohistochemical analysis of metastatic tumor tissue for estrogen and progesterone receptors was required. RESULTS: Twenty-five patients were enrolled and 3 were excluded. Six patients had tumors staining positive for both estrogen and progesterone receptors. There were no responders among 22 eligible patients. Six patients (27%) demonstrated stable disease as their best response. The median progression-free survival and overall survival were 1.9 and 14.4 months, respectively. A median total dose of 21.7 (range: 1.4 to 67.2) of danazol was administered. Therapy was discontinued in 5 eligible patients due to toxicity. Four of these patients experienced hepatic toxicity. CONCLUSIONS: Danazol has minimal activity in advanced, recurrent, or persistent endometrial carcinoma.

OBJECTIVE: The objective was to compare the handling characteristics and =6 month clinical outcome using a No. 1 long-term absorbable multifilament suture poly(L-lactide/glycolide) (PLG) or the permanent monofilament (No. 1) polypropolene using a continuous fascial closure. METHODS: During the 13-month study interval, 203 high-risk patients were enrolled in this randomized prospective trial. All were managed under a strict perioperative management protocol. RESULTS: There was no clinically significant difference in patient demographics. Seventy percent carried a diagnosis of abdominal malignancy. The mean body mass index of the population was 33.1. Wound variables including incision length, incision site, measured subcutaneous tissue thickness, and method of subcutaneous dissection did not differ. During the evaluation of suture handling properties PLG was judged to be statistically superior (P < 0.001) in lack of springback, knot tie-down smoothness, knot security, knot strength, and surgical hand. The monofilament suture was judged superior (P < 0001) in ease of tissue passage. There was no difference in incisional pain, suture rejection, superficial wound dehiscence, infection, seroma, or hernia. CONCLUSION: PLG suture represents a suitable nonpermanent suture alternative for fascial closure in patients at risk for poor wound outcome.

OBJECTIVE: The goal of this study was to determine the outcomes of stage IC endometrial carcinoma patients who are managed with and without adjuvant radiation therapy after comprehensive surgical staging. METHODS: Patients with FIGO stage IC adenocarcinoma of the endometrium diagnosed from 1988 to 1999 were identified from tumor registry databases at four institutions. A retrospective chart review identified 220 women who underwent comprehensive surgical staging including a total hysterectomy, bilateral salpingo-oophorectomy, pelvic/paraaortic lymphadenectomy, and peritoneal cytology. RESULTS: Of the 220 stage IC patients, 56 (25%) patients received adjuvant brachytherapy (BT), 19 (9%) received whole-pelvis radiation (WPRT), and 24 (11%) received both WPRT and BT. One hundred twenty-one patients (55%) did not receive adjuvant radiation. There were 6 recurrences (6%) in the radiated group and 14 (12%) in the observation group (P = 0.20). Seven of fourteen recurrences in the observation group were local, and all local recurrences were salvaged with radiation therapy. Two of seven distant recurrences in this group were also salvaged with surgery and chemotherapy. The overall salvage rate for the observation group was 64%. There was a statistical difference in 5-year disease-free survival between the radiated and observation groups (93% vs 75%, P = 0.013). However, the 5-year overall survival was similar in the two groups (92% vs 90%, P = 0.717). CONCLUSION: Adjuvant radiation therapy improves disease-free survival in surgical stage IC patients; however, overall survival is not improved with adjuvant radiation therapy since the majority of local recurrences in conservatively managed patients can be salvaged with radiation therapy.
