ARIA II: a randomized controlled trial of near-infrared Angiography during RectosIgmoid resection and Anastomosis in women with ovarian cancer.

BACKGROUND: Ovarian cancer with extensive metastatic disease involving pelvic structures often requires rectosigmoid resection for complete gross resection; however, it is associated with increased surgical morbidity. There are limited data, and none in ovarian cancer, on near-infrared assessment of perfusion in rectosigmoid resections with anastomosis. PRIMARY OBJECTIVE: To compare the rate of pelvic complications (pelvic abscesses, anastomotic leaks, and infections) within 30 days of surgery with and without near-infrared assessment of perfusion at time of rectosigmoid resection and re-anastomosis in patients undergoing cytoreductive surgery for ovarian cancer. STUDY HYPOTHESIS: We hypothesize the use of near-infrared technology (intravenous indocyanine green and endoscopic near-infrared fluorescence imaging), compared with standard intra-operative assessment, to evaluate anastomotic perfusion at time of rectosigmoid resection and re-anastomosis will result in lower rates of post-operative pelvic complications. TRIAL DESIGN: This is a planned multicenter randomized controlled trial. Patients who undergo rectosigmoid resection as part of their ovarian cytoreductive surgery will be randomized 1:1 to standard assessment of anastomosis with the surgeon's usual technique (control arm) or assessment with near-infrared angiography using indocyanine green and endoscopic fluorescence imaging (experimental arm). Randomization will occur after rectosigmoid resection has been completed and the surgeon declares their plan to create a diverting ostomy. Randomization will be stratified by plan for diverting ostomy. MAJOR INCLUSION/EXCLUSION CRITERIA: Main inclusion criteria include patients with primary or recurrent ovarian, fallopian tube, or primary peritoneal cancer who are scheduled for cytoreductive surgery with suspected need for low-anterior rectosigmoid resection. PRIMARY ENDPOINT: Rate of 30-day post-operative pelvic complications. SAMPLE SIZE: 310 (155 per arm) ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Q2 2027 and Q4 2027, respectively. TRIAL REGISTRATION: NCT04878094.

Adenoid cystic carcinoma of the Bartholin's gland is underpinned by MYB- and MYBL1- rearrangements.

OBJECTIVE: Adenoid cystic carcinoma (AdCC) of the Bartholin's gland (AdCC-BG) is a very rare gynecologic vulvar malignancy. AdCC-BGs are slow-growing but locally aggressive and are associated with high recurrence rates. Here we sought to characterize the molecular underpinning of AdCC-BGs. METHODS: AdCC-BGs (n = 6) were subjected to a combination of RNA-sequencing, targeted DNA-sequencing, reverse-transcription PCR, fluorescence in situ hybridization (FISH) and MYB immunohistochemistry (IHC). Clinicopathologic variables, somatic mutations, copy number alterations and chimeric transcripts were assessed. RESULTS: All six AdCC-BGs were biphasic, composed of ductal and myoepithelial cells. Akin to salivary gland and breast AdCCs, three AdCC-BGs had the MYB::NFIB fusion gene with varying breakpoints, all of which were associated with MYB overexpression by IHC. Two AdCC-BGs were underpinned by MYBL1 fusion genes with different gene partners, including MYBL1::RAD51B and MYBL1::EWSR1 gene fusions, and showed MYB protein expression. Although the final AdCC-BG studied had MYB protein overexpression, no gene fusion was identified. AdCC-BGs harbored few additional somatic genetic alterations, and only few mutations in cancer-related genes were identified, including GNAQ, GNAS, KDM6A, AKT1 and BCL2, none of which were recurrent. Two AdCC-BGs, both with a MYB::NFIB fusion gene, developed metastatic disease. CONCLUSIONS: AdCC-BGs constitute a convergent phenotype, whereby activation of MYB or MYBL1 can be driven by the MYB::NFIB fusion gene or MYBL1 rearrangements. Our observations further support the notion that AdCCs, irrespective of organ site, constitute a genotypic-phenotypic correlation. Assessment of MYB or MYBL1 rearrangements may be used as an ancillary marker for the diagnosis of AdCC-BGs.

Patient-reported symptoms after minimally invasive hysterectomy and association with postoperative complications.

OBJECTIVE: To describe patient-reported postoperative symptoms and to evaluate the use of digital symptom tracking and alerts to detect postoperative complications. METHODS: We retrospectively reviewed patients who underwent a minimally invasive hysterectomy and enrolled in our Recovery Tracker program from 4/5/17-12/31/21. The Recovery Tracker is an at-home virtual tool used to track patient-reported postoperative symptoms for 10 days. Predefined thresholds for "red" and "yellow" alerts are based on symptom severity and timing. Data on patient demographics, surgery, and postoperative course were collected to evaluate the association of alerts with complications and compare outcomes of patients who did/did not enroll in the program. RESULTS: Of 2362 eligible patients, 1694 (71.7%) enrolled in the Recovery Tracker program. Pain was the most severe symptom, followed by fatigue. Eighty-seven patients experienced 102 complications (5.1% complication rate) and 32 experienced 39 grade ≥ 2 complications (1.9% severe complication rate). Excluding complications that occurred prior to Recovery Tracker use, 1673 patients experienced 28 grade ≥ 2 complications. Of 345 patients (20.6%) who triggered a red alert, 13 (3.8%) had a grade ≥ 2 complication. Of 1328 patients (79.4%) with no red alerts, 15 (1.13%) had a grade ≥ 2 complication. Relative risk of a grade ≥ 2 complication if a red alert was triggered was 3.25 (95% CI: 1.6-6.9, P = .002). Rate of severe complications was significantly higher among patients who did not use the tool (3.3% vs 1.9%; P = .04). CONCLUSIONS: The Recovery Tracker tool may assist in early identification of postoperative symptoms after minimally invasive hysterectomy.

Ovarian cancer recurrence detection may not require in-person physical examination: an MSK team ovary study.

OBJECTIVE: Given the inconvenience and financial burden of frequent ovarian cancer surveillance and the risks of in-person visits due to COVID-19, which have led to the acceleration of telehealth adaptation, we sought to assess the role of in-person physical examination for the detection of ovarian cancer recurrence among patients enrolled in a routine surveillance program. METHODS: This was a retrospective study of patients initially seen from January 2015 to December 2017 who experienced ovarian cancer recurrence during first clinical remission. Descriptive statistics and bivariate analyses were performed to compare differences in detection methods and in patient and disease characteristics. RESULTS: Among 147 patients who met our inclusion criteria, there were no recurrences detected by physical examination alone. Forty-six (31%) patients had recurrence first detected by tumor marker, 81 (55%) by radiographic scan, 17 (12%) by presentation of new symptoms, and 3 (2%) by biopsies taken during non-oncological surgery. One hundred and eleven patients (75%) had multiple positive findings at the time of recurrence. Of all 147 patients, 48 (33%) had symptoms, 21 (14%) had physical examination findings, 106 (72%) had increases in tumor markers, and 141 (96%) had changes on imaging. CONCLUSIONS: In-person physical examination was not a primary means of detection for ovarian cancer recurrence for any patient. Substituting in-person visits for virtual visits that include patient-reported symptoms, alongside a regular surveillance protocol that includes tumor marker testing and imaging, may be a suitable approach for the detection of ovarian cancer recurrence while also reducing patient inconvenience and risks to health.

Clinical, Morphologic, and Molecular Features Associated With Ovarian Metastases From Pattern A Endocervical Adenocarcinomas.

Ovarian metastases from endocervical adenocarcinomas (EAs) are rare but well-described. Silva Pattern A tumors have been reported to pose essentially no risk of lymph node metastases or recurrence. We describe a cohort of patients with Silva Pattern A EAs with ovarian metastases, as well as involvement of other sites. Eight pattern A EAs with ovarian metastases (4 synchronous, 4 metachronous) were identified from our institution's pathologic archives (2008-2021). Clinicopathologic and molecular features for each case were recorded. All patients were treated by hysterectomy; in each case, the entire tumor was submitted for histologic evaluation. The synchronous metastases were all clinically suspected to be ovarian primary tumors; EAs with metachronous ovarian involvement were confined to the uterus at initial diagnosis, with ovarian metastasis occurring 5 to 171 months after hysterectomy. Morphologically, all tumors were predominantly gland-forming, 5/8 (63%) displayed prominent mucinous differentiation, and 5/8 (63%) involved the corpus. All EAs were either noninvasive (exophytic/papillary/more complex than adenocarcinoma in situ) or showed nondestructive cervical stromal invasion to a depth of 5 mm or less. In the 5 tumors tested by next-generation sequencing, ARID1A, GNAS, and KRAS mutations were detected in 2 (40%), 3 (60%), and 4 (80%) cases, respectively. All 6 patients with follow-up (range, 32 to 181 mo; median, 99.5 mo) had at least 1 recurrence. All but one are without evident disease at last clinical assessment. In an otherwise typical Silva Pattern A EA, corpus involvement, mucinous differentiation, and certain gene mutations may be associated with risk for synchronous or metachronous ovarian metastases.

Robotic Surgery in the Frail Elderly: Analysis of Perioperative Outcomes.

PURPOSE: The frail are considered at higher risk for unfavorable surgical outcomes (major complications/mortality). We assessed the safety of and outcomes associated with robotic surgery in the frail elderly undergoing gynecologic procedures. METHODS: We identified patients aged ≥ 65 years who underwent a robotic procedure between May 2007 and December 2016. Frailty was defined as the presence of at least three of five frailty factors-more than five comorbidities, low physical activity, weight loss, exhaustion, and fatigue. Perioperative outcomes were recorded. We compared variables among frail and non-frail patients and performed a multivariate logistic regression to detect variables associated with major complications (≥ grade 3) or 90-day mortality. RESULTS: We identified 982 patients: 71 frail and 911 non-frail patients. Median age was 71 years. Median BMI was 29.8 kg/m2. Thirty-four patients (3.5%) had a 30-day readmission. Seventy-seven (7.8%) had a postoperative complication, of which 23 (2.3%) were major. Ninety-day mortality was 0.5%. There were significant differences with regard to age (P < 0.001), body mass index (BMI) (P < 0.001) and performance status (P < 0.001); the frail were more likely to have had surgery for oncologic reasons (P = 0.047). There were differences in hospital stay (P < 0.001), postoperative (P = 0.042) and major complications (P = 0.007), and 90-day mortality (P = 0.05). At multivariable logistic regression, age ≥ 85 was associated with major complications. BMI, performance status, and major complications were associated with 90-day mortality. CONCLUSIONS: The frail elderly have longer hospital stays and more complications after surgery than the general population, consistent with the reported literature. Careful selection of surgical candidates is required.

A Review of Immune Checkpoint Blockade Therapy in Endometrial Cancer.

Approximately 30% of primary endometrial cancers are microsatellite instability high/hypermutated (MSI-H), and 13% to 30% of recurrent endometrial cancers are MSI-H or mismatch repair deficient (dMMR). Given the presence of immune dysregulation in endometrial cancer as described, immune checkpoint blockade (ICB) has been explored as a therapeutic mechanism, both as monotherapy and in combination with cytotoxic chemotherapy, other immunotherapy, or targeted agents. In MSI-H or dMMR advanced endometrial cancers, PD-1 inhibitors dostarlimab and pembrolizumab have shown response rates of 49% and 57%, respectively, whereas PD-L1 inhibitors avelumab and durvalumab have shown response rates of 27% and 43%, respectively. In microsatellite stable (MSS) or PD-L1-positive advanced endometrial cancers, modest activity of PD-1 inhibitors nivolumab and dostarlimab and PD-L1 inhibitors atezolizumab, avelumab, and durvalumab has been seen, with response rates ranging from 3% to 23%. Based on substantial activity in a phase Ib/II study, the U.S. Food and Drug Administration (FDA) granted lenvatinib and pembrolizumab combination therapy accelerated approval in 2019 for the treatment of advanced endometrial cancer that is not MSI-H or dMMR and has progressed following prior therapy. Although these developments have been highly impactful, a more robust understanding of the molecular and immunologic drivers of response and resistance will be critical to optimally design next-generation studies in endometrial cancer.

Current and novel mapping substances in gynecologic cancer care.

Many tracers have been introduced into current medical practice with the purpose of improving lymphatic mapping techniques, anatomic visualization, and organ/tissue perfusion assessment. Among them, three tracers have dominated the field: indocyanine green, technetium-99m radiocolloid (Tc99m), and blue dye. Tc99m and blue dye are used individually or in combination; however, given particular challenges with these tracers, such as the need for a preoperative procedure by nuclear medicine and cost, other options have been sought. Indocyanine green has proven to be a promising alternative for certain procedures, as it is easy to use and has quick uptake. Its use in the management of gynecologic cancers was first described for sentinel lymph node mapping in cervical cancer, and later for endometrial and vulvar cancers. This review provides an in-depth look at these mapping substances, their uses, and the potential for new discoveries.

In vitro and in vivo activity of sacituzumab govitecan, an antibody-drug conjugate targeting trophoblast cell-surface antigen 2 (Trop-2) in uterine serous carcinoma.

OBJECTIVE: Uterine serous carcinoma (USC) is an aggressive variant of endometrial cancer with poor prognosis. Sacituzumab govitecan (SG) is a novel antibody-drug-conjugate (ADC) targeting trophoblast cell-surface antigen 2 (Trop-2), a transmembrane-calcium-signal-transducer, to deliver SN-38, the active metabolite of irinotecan. The objective of this study was to evaluate the expression of Trop-2 in USC and the preclinical activity of SG against primary USC cell-lines and xenografts. METHODS: We used immunohistochemistry (IHC) and flow-cytometry-based assays to evaluate Trop-2 expression and cell-viability in USC tissue and primary tumor-cell-lines after exposure to SG, non-targeting control ADC, and naked antibody hRS7-IgG. Antibody-dependent-cell-cytotoxicity (ADCC) against Trop-2+ and Trop-2- USC cell-lines was evaluated in vitro using 4-hr-Chromium-release-assays. In vivo activity of SG was tested against Trop-2+ USC xenografts by intravenous administration of SG, control ADC, and hRS7. RESULTS: Trop-2 expression by IHC was detected in 95.1% of USC samples (99/104). Primary tumor cell-lines overexpressing Trop-2 were significantly more sensitive to SG when compared to control ADC (p <0.05). Both SG and hRS7 mediated ADCC in Trop2+ USC cell-lines while no cytotoxicity was detected against Trop-2- cells. SG induced significant bystander killing of Trop-2- tumors when admixed with Trop-2+ tumors. SG caused growth-inhibition and increased survival in SG treated mice harboring Trop-2+ xenografts when compared to controls (p <0.05). CONCLUSIONS: SG is remarkably active against USC overexpressing Trop-2 in vitro and in vivo. Our results combined with SG clinical responses recently reported against multiple chemotherapy resistant human tumors further support clinical development of SG in USC patients with advanced/recurrent disease.

Evaluating the Impact of a New Smartphone Texting Tool on Patient Care in Obstetrics, an Emergent Healthcare Setting.

BACKGROUND: Hospitals across the country are investing millions of dollars to adopt new Health Insurance Portability and Accountability Act (HIPAA)-compliant secure text messaging systems. However, in nearly all cases, these implementations are occurring without evaluation of their impact on patient care. OBJECTIVE: To evaluate perceived impact on patient care and workflow of new text messaging system implemented in obstetrics at Yale-New Haven Hospital and to inform guidelines for future implementations in emergent settings. METHODS: A new HIPAA-compliant texting system was implemented in obstetrics in 2016. Before implementation of the new system, residents and nurses were surveyed on perceived effect of communication system (pagers with text receiving, service mobile phones, personal cell phones) on clinical workflow and patient care using 5-point Likert scale and open-ended questions. Following roll-out (1 and 6 months), both teams were surveyed with same questions. Results were compared using Wilcoxon-Mann-Whitney test (0-1 months and then 0-6 months). Open-ended question results were qualitatively compared for recurrent unifying themes. RESULTS: In both nursing and resident domains, 1 month after implementation, the new communication system was perceived to significantly improve efficiency and patient care across all metrics. After 6 months, this effect decayed in nearly all categories (including efficiency, real-time communication, and knowledge of covering provider). The exception was nurse's knowledge of which resident to contact and resident's timely evaluation of patient, for which we observed sustained improvements. System shortcomings identified included interrupted connection (i.e., dropped calls), dysfunctional and inaccurate alert system, and unclear identification of the covering provider. CONCLUSION: A new text-messaging-based communication system may improve efficiency and patient care in emergent settings, but system shortcomings can substantially erode potential benefits over time. We recommend implementers evaluate new systems for a set of specific functional requirements to increase probability of sustained improvement and decrease risk of poor patient outcomes.

A Novel Approach to Combined Vaginal and Laparoscopic Gynecological Surgery.

BACKGROUND AND OBJECTIVES: In this case series, we propose a novel approach to combined vaginal and laparoscopic surgery in which a posterior colpotomy and 2 5-mm abdominal incisions are used to perform benign gynecological procedures. We seek to assess the safety and feasibility of this technique in difficult surgical candidates such as those with obesity or prior laparotomies, as well as to detail intra- and postoperative complications associated with the procedure. METHODS: We collected demographic, clinical, intra-operative, and postoperative data on 45 women who underwent a combined vaginal and laparoscopic gynecological surgery for benign indications by a single surgeon between February 2013 and August 2017. RESULTS: From February 2013 through August 2017, 45 women underwent a combined vaginal and laparoscopic surgery at 2 institutions. Procedures included adnexal surgery (n = 32, 71%), and total hysterectomy (n = 13, 29%). Of patients who underwent adnexal surgery, two had minor postoperative complications. No patients had major complications. In addition, no patients had postoperative vaginal infections or pelvic abscesses, and there were no readmissions within 30 days after the procedures. CONCLUSION: Our proposed combined vaginal and laparoscopic approach to benign gynecological surgery can be utilized in difficult surgical candidates including those with obesity, nulliparous patients, and those with prior abdominal surgery. Our data has shown that this approach is safe and effective.

Ten-Year Comparison Study of Type 1 and 2 Endometrial Cancers: Risk Factors and Outcomes.

AIMS: To compare baseline risk factors for type 1 vs. 2 endometrial cancers and analyze these risk factors for association with overall survival and time to recurrence. METHODS: Retrospective review of 816 consecutive endometrial cancer cases was conducted with diagnosis from January 2005 to December 2010 and clinical course until 2016. Risk factors, treatment, recurrence, and death were compared using 2 sample t tests, χ2 test and Cox Regression models. RESULTS: There were 550 cases of type 1 and 266 cases of type 2 cancer. Patients with type 2 disease were older (p < 0.001), less obese (p = 0.03), non-white (p < 0.001), and menopausal (p = 0.02). There was no difference in use of oral contraceptives, hormone replacement therapy (HRT), smoking, or major cardiovascular disease. Cox Regression models showed that type 2 disease (p < 0.001) and advanced stage (p = 0.001) were associated with recurrence. CONCLUSIONS: Consistent with previous literature, our analysis found that type 2 cancer is more common in non-white, older, and less obese patients and associated with higher mortality and recurrence. However, inconsistent with previous literature, we found no association between type 2 cancer and diabetes mellitus or use of HRT. These factors should be considered when approaching patients with endometrial cancer.

Is Robotic-Assisted Surgery Safe in the Elderly Population? An Analysis of Gynecologic Procedures in Patients ≥ 65 Years Old.

BACKGROUND: The elderly population is expanding worldwide but is underrepresented in clinical trials. We sought to assess the safety of robotic gynecologic surgery in an elderly cohort and to identify factors associated with unfavorable outcomes. METHODS: All patients ≥ 65 years who underwent a robotically assisted procedure at a single institution between May 2007 to December 2016 were divided into three age groups: 65-74 (Group 1); 75-84 (Group 2); ≥ 85 (Group 3). Perioperative outcomes were recorded in patients who did not require conversion to laparotomy. We compared clinical variables among groups and performed multivariate logistic regression to detect variables associated with major complications (≥ Grade 3) or 90-day mortality. RESULTS: We retrospectively identified 982 cases: 685 in Group 1; 249 in Group 2; 48 in Group 3. Median age = 71 years. Median BMI = 28.9. Malignancy was documented in 72.8% of cases; the majority were endometrial cancer (61.8%). Thirty-four patients (3.5%) were readmitted within 30 days. Seventy-seven (7.8%) had a postoperative complication, and 23 (2.3%) had a major complication. Ninety-day mortality was 0.5%. There was significant difference between groups with respect to body mass index (P = 0.026), ECOG PS (P ≤ 0.001), > 5 comorbidities (P = 0.005), hospital stay (P < 0.001), major complications (P = 0.001), and 90-day mortality (P < 0.001). On multivariable logistic regression, age ≥ 85 years was associated with major complications. Body mass index, age ≥ 85 years, and major complications were significantly associated with 90-day mortality. CONCLUSIONS: Robotic-assisted surgery appears to be safe in an elderly cohort. The incidence of overall and major complications is consistent with those reported in the literature. Patients ≥ 85 years old appear to be at higher risk of unfavorable outcomes.

Novel targeted therapies in ovarian and uterine carcinosarcomas.

Carcinosarcomas (CSs) of the uterus and ovary are rare biologically aggressive tumors with poor prognosis. The development of novel, effective treatment strategies against CSs of the female genital tract remains an unmet medical need. Whole-exome sequencing studies have recently demonstrated mutations or aberrant activation of multiple genes/pathways in CSs including HER2, PI3K/AKT/mTOR, EGFR, MAPK, genes related to histones and chromatin structure, and genes related to cell-cycle regulation. The carcinomatous component of these biphasic tumors is suggested to be the catalyst in CS tumorigenesis. This article reviews the genetic landscapes and explores novel targeted treatment modalities against this deadly gynecologic tumor.

In Vitro and In Vivo Activity of IMGN853, an Antibody-Drug Conjugate Targeting Folate Receptor Alpha Linked to DM4, in Biologically Aggressive Endometrial Cancers.

Grade 3 endometrioid and uterine serous carcinomas (USC) account for the vast majority of endometrial cancer deaths. The purpose of this study was to determine folic acid receptor alpha (FRα) expression in these biologically aggressive (type II) endometrial cancers and evaluate FRα as a targetable receptor for IMGN853 (mirvetuximab soravtansine). The expression of FRα was evaluated by immunohistochemistry (IHC) and flow cytometry in 90 endometrioid and USC samples. The in vitro cytotoxic activity and bystander effect were studied in primary uterine cancer cell lines expressing differential levels of FRα. In vivo antitumor efficacy of IMGN853 was evaluated in xenograft/patient-derived xenograft (PDX) models. Semiquantitative IHC analysis indicated that 41% of the USC patients overexpress FRα. Further, overexpression of FRα (i.e., 2+) was detected via flow cytometry in 22% (2/9) of primary endometrioid and in 27% (3/11) of primary USC cell lines. Increased cytotoxicity was seen with IMGN853 treatment compared with control in 2+ expressing uterine tumor cell lines. In contrast, tumor cell lines with low FRα showed no difference when exposed to IMGN853 versus control. IMGN853 induced bystander killing of FRα = 0 tumor cells. In an endometrioid xenograft model (END(K)265), harboring 2+ FRα, IMGN853 treatment showed complete resolution of tumors (P < 0.001). Treatment with IMGN853 in the USC PDX model (BIO(K)1), expressing 2+ FRα, induced twofold increase in median survival (P < 0.001). IMGN853 shows impressive antitumor activity in biologically aggressive FRα 2+ uterine cancers. These preclinical data suggest that patients with chemotherapy resistant/recurrent endometrial cancer overexpressing FRα may benefit from this treatment. Mol Cancer Ther; 17(5); 1003-11. ©2018 AACR.

An eQTL variant of ZXDC is associated with IFN-γ production following Mycobacterium tuberculosis antigen-specific stimulation.

There is a large inter-individual variability in the response to Mycobacterium tuberculosis infection. In previous linkage analyses, we identified a major locus on chromosome region 8q controlling IFN-γ production after stimulation with live BCG (Bacillus Calmette-Guérin), and a second locus on chromosome region 3q affecting IFN-γ production triggered by the 6-kDa early secretory antigen target (ESAT-6), taking into account the IFN-γ production induced by BCG (IFNγ-ESAT6BCG). High-density genotyping and imputation identified ~100,000 variants within each linkage region, which we tested for association with the corresponding IFN-γ phenotype in families from a tuberculosis household contact study in France. Significant associations were replicated in a South African familial sample. The most convincing association observed was that between the IFNγ-ESAT6BCG phenotype and rs9828868 on chromosome 3q (p = 9.8 × 10-6 in the French sample). This variant made a significant contribution to the linkage signal (p < 0.001), and a trend towards the same association was observed in the South African sample. This variant was reported to be an eQTL of the ZXDC gene, biologically linked to monocyte IL-12 production through CCL2/MCP1. The identification of rs9828868 as a genetic driver of IFNγ production in response to mycobacterial antigens provides new insights into human anti-tuberculosis immunity.

The use of QuikClot combat gauze in cervical and vaginal hemorrhage.

QuikClot combat gauze is a synthetic hemostatic dressing used for hemorrhage control. There is a paucity of data describing the clinical use and hemostatic results of combat gauze in the obstetric and gynecologic setting. This case series demonstrates the use of combat gauze as an effective hemostatic agent when used as vaginal packing in cervical and vaginal hemorrhage. Hemostasis was achieved rapidly in all cases and further interventions were avoided. The combat gauze remained in place for a mean time of 15 h with no adverse side effects observed. The use of combat gauze as vaginal packing may provide an alternative option in the treatment of cervical and vaginal hemorrhage when other traditional conservative and surgical interventions fail or are unavailable.

Management of sexuality, intimacy, and menopause symptoms in patients with ovarian cancer.

Issues of sexuality, intimacy, and early menopause significantly impact the quality of life of patients following the diagnosis and treatment of ovarian cancer. These are undertreated problems. Successful treatment requires the provider's awareness of the problem, ability to identify it, and willingness to treat it. Unfortunately many providers do not address these issues in the pretreatment or perioperative period. Furthermore, patients do not often alert their providers to their symptoms. While systemic hormone therapy may improve many of the issues, they are not appropriate for all patients given their action on estrogen receptors. However, other nonhormonal treatments exist including selective serotonin reuptake inhibitors, antiepileptics, natural remedies, and pelvic floor physical therapy. In addition psychological care and the involvement of the partner can be helpful in managing the sexual health concerns of these patients. At the time of diagnosis or at initial consultation, women should be informed of the potential physiologic, hormonal, and psychosocial effects of ovarian cancer on sexuality and that there is a multimodal approach to dealing with symptoms.

Major Loci on Chromosomes 8q and 3q Control Interferon γ Production Triggered by Bacillus Calmette-Guerin and 6-kDa Early Secretory Antigen Target, Respectively, in Various Populations.

BACKGROUND: Interferon γ (IFN-γ) release assays (IGRAs) provide an in vitro measurement of antimycobacterial immunity that is widely used as a test for Mycobacterium tuberculosis infection. IGRA outcomes are highly heritable in various populations, but the nature of the involved genetic factors remains unknown. METHODS: We conducted a genome-wide linkage analysis of IGRA phenotypes in families from a tuberculosis household contact study in France and a replication study in families from South Africa to confirm the loci identified. RESULTS: We identified a major locus on chromosome 8q controlling IFN-γ production in response to stimulation with live bacillus Calmette-Guerin (BCG; LOD score, 3.81; P = 1.40 × 10(-5)). We also detected a second locus, on chromosome 3q, that controlled IFN-γ levels in response to stimulation with 6-kDa early secretory antigen target, when accounting for the IFN-γ production shared with that induced by BCG (LOD score, 3.72; P = 1.8 × 10(-5)). Both loci were replicated in South African families, where tuberculosis is hyperendemic. These loci differ from those previously identified as controlling the response to the tuberculin skin test (TST1 and TST2) and the production of TNF-α (TNF1). CONCLUSIONS: The identification of 2 new linkage signals in populations of various ethnic origins living in different M. tuberculosis exposure settings provides new clues about the genetic control of human antimycobacterial immunity.
