RATIONALE: Advanced bronchoscopy techniques such as electromagnetic navigation (EMN) have been studied in clinical trials, but there are no randomized studies comparing EMN with standard bronchoscopy. OBJECTIVES: To measure and identify the determinants of diagnostic yield for bronchoscopy in patients with peripheral lung lesions. Secondary outcomes included diagnostic yield of different sampling techniques, complications, and practice pattern variations. METHODS: We used the AQuIRE (ACCP Quality Improvement Registry, Evaluation, and Education) registry to conduct a multicenter study of consecutive patients who underwent transbronchial biopsy (TBBx) for evaluation of peripheral lesions. MEASUREMENTS AND MAIN RESULTS: Fifteen centers with 22 physicians enrolled 581 patients. Of the 581 patients, 312 (53.7%) had a diagnostic bronchoscopy. Unadjusted for other factors, the diagnostic yield was 63.7% when no radial endobronchial ultrasound (r-EBUS) and no EMN were used, 57.0% with r-EBUS alone, 38.5% with EMN alone, and 47.1% with EMN combined with r-EBUS. In multivariate analysis, peripheral transbronchial needle aspiration (TBNA), larger lesion size, nonupper lobe location, and tobacco use were associated with increased diagnostic yield, whereas EMN was associated with lower diagnostic yield. Peripheral TBNA was used in 16.4% of cases. TBNA was diagnostic, whereas TBBx was nondiagnostic in 9.5% of cases in which both were performed. Complications occurred in 13 (2.2%) patients, and pneumothorax occurred in 10 (1.7%) patients. There were significant differences between centers and physicians in terms of case selection, sampling methods, and anesthesia. Medical center diagnostic yields ranged from 33 to 73% (P = 0.16). CONCLUSIONS: Peripheral TBNA improved diagnostic yield for peripheral lesions but was underused. The diagnostic yields of EMN and r-EBUS were lower than expected, even after adjustment.

The relative infrequency of blunt carotid artery trauma prompted a multicenter review to determine the spectrum of injuries, treatment strategies, and neurologic outcome. During a six-year period, 60 carotid artery injuries from blunt mechanisms in 49 patients were treated at 11 institutions. There were 11 bilateral injuries. Injury mechanisms were diverse but involved motor vehicles in 35 (72%) patients. In 14 (29%) patients, significant neurologic deficits developed more than 12 hours after a normal admission neurologic examination. The diagnosis was confirmed by angiography in 42 (86%). Duplex ultrasound accurately demonstrated the arterial injury in 12 (86%) of 14 patients. Documented injuries included arterial thrombosis in 20 arteries, arterial dissection alone in 19, dissection with pseudoaneurysm in six, pseudoaneurysm alone in five, frank arterial disruption in seven, and carotid-cavernous fistula in three. Arterial dissection was managed nonsurgically in 15 (79%) of 19 cases, the majority with systemic anticoagulation. Arterial thrombosis was managed with supportive therapy alone for 16 (80%) of 20 arteries; most associated with fixed neurologic deficits. Pseudoaneurysm repair was performed for six (55%) injuries. Carotid-cavernous fistulas were treated in all three instances with balloon occlusion. Overall mortality was 16 of 49 patients (43%). Good neurologic outcome was achieved in 22 (45%) patients. We conclude that: (1) Neurologic symptoms may develop in a delayed fashion; prior clinical suspicion and diagnostic testing are essential; (2) arterial dissection without complete occlusion may effectively be managed by anticoagulation; (3) pseudoaneurysms in accessible anatomic locations can be repaired with good results; and (4) injuries with complete arterial thrombosis are associated with high mortality and poor neurologic outcome in proportion to the initial degree of neurologic impairment.

Nontraumatic hemorrhage of the adrenal gland is uncommon. The causes of such hemorrhage can be classified into five categories: (a) stress, (b) hemorrhagic diathesis or coagulopathy, (c) neonatal stress, (d) underlying adrenal tumors, and (e) idiopathic disease. Computed tomography (CT), ultrasonography (US), and magnetic resonance (MR) imaging play an important role in diagnosis and management. CT is the modality of choice for evaluation of adrenal hemorrhage in a patient with a history of stress or a hemorrhagic diathesis or coagulopathy (anticoagulant therapy). CT may yield the first clue to the diagnosis of adrenal insufficiency secondary to bilateral massive adrenal hemorrhage; such insufficiency is rare but life threatening. US is the modality of choice for evaluation of neonatal hematoma, and MR imaging is helpful for further characterization. MR imaging is also useful in the diagnosis of coexistent renal vein thrombosis. When an adrenal abscess is suspected, percutaneous aspiration and drainage under imaging guidance should be performed. Hemorrhage into an adrenal cyst or tumor can cause acute onset of symptoms and signs in a patient without discernible risk factors for adrenal hemorrhage. A hemorrhagic adrenal tumor should be suspected when CT or MR imaging reveals a hemorrhagic adrenal mass of heterogeneous attenuation or signal intensity that demonstrates enhancement.

PURPOSE: To evaluate the effectiveness of patient-controlled methylphenidate as compared with placebo in cancer patients with fatigue, as measured by the Functional Assessment for Chronic Illness Therapy-Fatigue (FACIT-F). PATIENTS AND METHODS: Patients with a fatigue score of at least 4 on a scale of 0 to 10 (0 = no fatigue, 10 = worst possible fatigue) and hemoglobin level of at least 10 g/dL were included. Patients were randomly assigned to receive 5 mg methylphenidate or placebo every 2 hours as needed (maximum of four capsules a day), for 7 days. Patients completed a daily diary including study drug record and fatigue intensity. A research nurse telephoned patients daily to assess toxicity and fatigue level. All patients were offered open-label methylphenidate for 4 weeks. FACIT-F and the Edmonton Symptom Assessment System (ESAS) were assessed at baseline, and days 8, 15, and 36. The FACIT-F fatigue subscore on day 8 was considered the primary end point. RESULTS: Of 112 patients randomly assigned, 52 patients in the methylphenidate and 53 in the placebo group were assessable for analysis. Fatigue intensity improved significantly on day 8 in both the methylphenidate and placebo groups. However, there was no significant difference in fatigue improvement by FACIT-F (P = .31) or ESAS (P = .14) between groups. In open-label phase, fatigue intensity maintained low as compared with baseline. No significant toxicities were observed. CONCLUSION: Both methylphenidate and placebo resulted in significant symptom improvement. Methylphenidate was not significantly superior to placebo after 1 week of treatment. Longer study duration is justified. The role of daily telephone calls from a research nurse should be explored as a palliative care intervention.

OBJECTIVE: There are limited data on the effects of financial distress (FD) on overall suffering and quality of life (QOL) of patients with advanced cancer (AdCa). In this cross-sectional study, we examined the frequency of FD and its correlates in AdCa. PATIENTS AND METHODS: We interviewed 149 patients, 77 at a comprehensive cancer center (CCC) and 72 at a general public hospital (GPH). AdCa completed a self-rated FD (subjective experience of distress attributed to financial problems) numeric rating scale (0 = best, 10 = worst) and validated questionnaires assessing symptoms (Edmonton Symptom Assessment System [ESAS]), psychosocial distress (Hospital Anxiety and Depression Scale [HADS]), and QOL (Functional Assessment of Cancer Therapy-General [FACT-G]). RESULTS: The patients' median age was 60 years (95% confidence interval [CI]: 58.6-61.5 years); 74 (50%) were female; 48 of 77 at CCC (62%) versus 13 of 72 at GPH (18%) were white; 21 of 77 (27%) versus 32 of 72 (38%) at CCC and GPH, respectively, were black; and 7 of 77 (9%) versus 27 of 72 (38%) at CCC and GPH, respectively, were Hispanic (p < .0001). FD was present in 65 of 75 at CCC (86%; 95% CI: 76%-93%) versus 65 of 72 at GPH (90%; 95% CI: 81%-96%; p = .45). The median intensity of FD at CCC and GPH was 4 (interquartile range [IQR]: 1-7) versus 8 (IQR: 3-10), respectively (p = .0003). FD was reported as more severe than physical distress, distress about physical functioning, social/family distress, and emotional distress by 45 (30%), 46 (31%), 64 (43%), and 55 (37%) AdCa, respectively (all significantly worse for patients at GPH) (p < .05). AdCa reported that FD was affecting their general well-being (0 = not at all, 10 = very much) with a median score of 5 (IQR: 1-8). FD correlated (Spearman correlation) with FACT-G (r = -0.23, p = .0057); HADS-anxiety (r = .27, p = .0014), ESAS-anxiety (r = .2, p = .0151), and ESAS-depression (r = .18, p = .0336). CONCLUSION: FD was very frequent in both groups, but median intensity was double among GPH patients. More than 30% of AdCa rated FD to be more severe than physical, family, and emotional distress. More research is needed to better characterize FD and its correlates in AdCa and possible interventions. IMPLICATIONS FOR PRACTICE: Financial distress is an important and common factor contributing to the suffering of advanced cancer patients and their caregivers. It should be suspected in patients with persistent, refractory symptom expression. Early identification, measurement, and documentation will allow clinical teams to develop interventions to improve financial distress and its impact on quality of life of advanced cancer patients.

The concept of a natural rate of unemployment, or nonaccelerating inflation rate of unemployment (NAIRU), remains controversial after twenty-five years. This essay presents a brief for no-confidence, in four parts. First, the theoretical case for the natural rate is not compelling. Second, the evidence for a vertical Phillips curve and the associated accelerationist hypothesis that lowering unemployment past the NAIRU leads to unacceptable acceleration of inflation is weak. Third, economists have failed to reach professional consensus on estimating the NAIRU. Fourth, adherence to the concept as a guide to policy has major social costs but negligible benefits.

PURPOSE: We examined in a prospective, randomized, international clinical trial the performance of a previously defined 30-gene predictor (DLDA-30) of pathologic complete response (pCR) to preoperative weekly paclitaxel and fluorouracil, doxorubicin, and cyclophosphamide (T/FAC) chemotherapy, and assessed if DLDA-30 also predicts increased sensitivity to FAC-only chemotherapy. We compared the pCR rates after T/FAC versus FACx6 preoperative chemotherapy. We also did an exploratory analysis to identify novel candidate genes that differentially predict response in the two treatment arms. EXPERIMENTAL DESIGN: Two hundred and seventy-three patients were randomly assigned to receive either weekly paclitaxel × 12 followed by FAC × 4 (T/FAC, n = 138), or FAC × 6 (n = 135) neoadjuvant chemotherapy. All patients underwent a pretreatment fine-needle aspiration biopsy of the tumor for gene expression profiling and treatment response prediction. RESULTS: The pCR rates were 19% and 9% in the T/FAC and FAC arms, respectively (P < 0.05). In the T/FAC arm, the positive predictive value (PPV) of the genomic predictor was 38% [95% confidence interval (95% CI), 21-56%], the negative predictive value was 88% (95% CI, 77-95%), and the area under the receiver operating characteristic curve (AUC) was 0.711. In the FAC arm, the PPV was 9% (95% CI, 1-29%) and the AUC was 0.584. This suggests that the genomic predictor may have regimen specificity. Its performance was similar to a clinical variable-based predictor nomogram. CONCLUSIONS: Gene expression profiling for prospective response prediction was feasible in this international trial. The 30-gene predictor can identify patients with greater than average sensitivity to T/FAC chemotherapy. However, it captured molecular equivalents of clinical phenotype. Next-generation predictive markers will need to be developed separately for different molecular subsets of breast cancers.

BACKGROUND: Genital herpes simplex virus (HSV) infection is one of the most common viral sexually transmitted infections. The majority of women with genital herpes will have a recurrence during pregnancy. Transmission of the virus from mother to fetus typically occurs by direct contact with virus in the genital tract during birth. OBJECTIVES: To assess the effectiveness of antenatal antiviral prophylaxis for recurrent genital herpes on neonatal herpes and maternal recurrences at delivery. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2006, Issue 4), MEDLINE (January 1966 to February 2007) and EMBASE (January 1974 to February 2007; handsearched conference proceedings; reviewed bibliographies of all relevant articles for further references; and contacted experts in the field. SELECTION CRITERIA: Randomized controlled trials which assessed the effectiveness of antivirals compared to placebo or no therapy, on neonatal herpes and maternal disease endpoints among pregnant women with genital herpes. DATA COLLECTION AND ANALYSIS: Two authors independently applied study selection criteria and extracted data. MAIN RESULTS: Seven randomized controlled trials (1249 participants) which met our inclusion criteria compared acyclovir to placebo or no treatment (five trials) and valacyclovir to placebo (two trials). The effect of antepartum antiviral prophylaxis on neonatal herpes could not be estimated. There were no cases of symptomatic neonatal herpes in the included studies in either the treatment or placebo groups. Women who received antiviral prophylaxis were significantly less likely to have a recurrence of genital herpes at delivery (relative risk (RR) 0.28, 95% confidence interval (CI) 0.18 to 0.43, I(2 )= 0%). Women who received antiviral prophylaxis were also significantly less likely to have a cesarean delivery for genital herpes (RR 0.30, 95% CI 0.20 to 0.45, I(2) = 27.3%). Women who received antiviral prophylaxis were significantly less likely to have HSV detected at delivery (RR 0.14, 95% CI 0.05 to 0.39, I(2) = 0%). AUTHORS' CONCLUSIONS: Women with recurrent genital herpes simplex virus should be informed that the risk of neonatal herpes is low. There is insufficient evidence to determine if antiviral prophylaxis reduces the incidence of neonatal herpes. Antenatal antiviral prophylaxis reduces viral shedding and recurrences at delivery and reduces the need for cesarean delivery for genital herpes. Limited information exists regarding the neonatal safety of prophylaxis. The risks, benefits, and alternatives to antenatal prophylaxis should be discussed with women who have a history and prophylaxis initiated for women who desire intervention.

OBJECTIVE: To establish a trauma preventable/potentially preventable death rate (PPPDR) within a heavily populated county in Texas. SUMMARY: The National Academies of Sciences estimated the trauma preventable death rate in the United States to be 20%, issued a call for zero preventable deaths, while acknowledging that an accurate preventable death rate was lacking. In this absence, effective strategies to improve quality of care across trauma systems will remain difficult. METHODS: A retrospective review of death-related records that occurred during 2014 in Harris County, TX, a diverse population of 4.4 million. Patient demographics, mechanism of injury, cause, timing, and location of deaths were assessed. Deaths were categorized using uniform criteria and recorded as preventable, potentially preventable or nonpreventable. RESULTS: Of 1848 deaths, 85% had an autopsy and 99.7% were assigned a level of preventability, resulting in a trauma PPPDR of 36.2%. Sex, age, and race/ethnicity varied across preventability categories (P < 0.01). Of 847 prehospital deaths, 758 (89.5%) were nonpreventable. Among 89 prehospital preventable/potentially preventable (P/PP) deaths, hemorrhage accounted for 55.1%. Of the 657 initial acute care setting deaths, 292 (44.4%) were P/PP; of these, hemorrhage, sepsis, and traumatic brain injury accounted for 73.3%. Of 339 deaths occurring after initial hospitalization, 287 (84.7%) were P/PP, of these 117 resulted from sepsis and 31 from pulmonary thromboembolism, accounted for 51.6%. CONCLUSIONS: The trauma PPPDR was almost double that estimated by the National Academies of Sciences. Data regarding P/PP deaths offers opportunity to target research, prevention, intervention, and treatment corresponding to all phases of the trauma system.

In the search for sustainability and stability, a central tenet of social entrepreneurship holds that revenue diversification is desirable. Business and nonprofit researchers have long argued that by establishing and maintaining multiple streams of funding, including some combination of earned income, government contracts, foundation and corporate grants, and individual contributions, organizations are able to avoid excessive dependence on any single revenue source, stabilize their financial positions, and thereby reduce the risk of financial crises or interruptions in funding. By studying a large sample of nonprofit organizations in the US, this paper investigates whether this basic claim about the desirability of revenue diversification is both correct and complete. Against the dominant trend in the literature that focuses on the risks of revenue concentration, we find that nonprofit organizations that have highly concentrated and specialized forms of revenue actually experience some significant benefits, in the form of lower administrative and fund-raising expenses. However, these savings are associated with greater exposure to swings in an organization's financial position. Based on our study of the broader world of nonprofit organizations, we conclude that social entrepreneurs likely face a more complex set of choices about the composition of their revenue than previous research has suggested.

Abstract Objective To determine whether robotic ventral hernia repair is associated with fewer days in the hospital 90 days after surgery compared with laparoscopic repair. Design Pragmatic, blinded randomized controlled trial. Setting Multidisciplinary hernia clinics in Houston, USA. Participants 124 patients, deemed appropriate candidates for elective minimally invasive ventral hernia repair, consecutively presenting from April 2018 to February 2019. Interventions Robotic ventral hernia repair (n=65) versus laparoscopic ventral hernia repair (n=59). Main outcome measures The primary outcome was number of days in hospital within 90 days after surgery. Secondary outcomes included emergency department visits, operating room time, wound complications, hernia recurrence, reoperation, abdominal wall quality of life, and costs from the healthcare system perspective. Outcomes were pre-specified before data collection began and analyzed as intention to treat. Results Patients from both groups were similar at baseline. Ninety day follow-up was completed in 123 (99%) patients. No evidence was seen of a difference in days in hospital between the two groups (median 0 v 0 days; relative rate 0.90, 95% confidence interval 0.37 to 2.19; P=0.82). For secondary outcomes, no differences were noted in emergency department visits, wound complications, hernia recurrence, or reoperation. However, robotic repair had longer operative duration (141 v 77 min; mean difference 62.89, 45.75 to 80.01; P≤0.001) and increased healthcare costs ($15 865 (£12 746; €14 125) v $12 955; cost ratio 1.21, 1.07 to 1.38; adjusted absolute cost difference $2767, $910 to $4626; P=0.004). Among patients with robotic ventral hernia repair, two had an enterotomy compared none with laparoscopic repair. The median one month postoperative improvement in abdominal wall quality of life was 3 with robotic ventral hernia repair compared with 15 following laparoscopic repair. Conclusion This study found no evidence of a difference in 90 day postoperative hospital days between robotic and laparoscopic ventral hernia repair. However, robotic repair increased operative duration and healthcare costs. Trial registration Clinicaltrials.gov NCT03490266 .

Computed tomography (CT) plays a leading role in the evaluation of nonmalignant disease of the adrenal gland. CT is highly accurate in the localization of adrenal masses in patients with diseases associated with hyperfunctioning adrenal glands such as Cushing syndrome and Cushing disease, Conn syndrome, adrenal tumors leading to virilization or feminization, and pheochromocytomas. CT permits a specific diagnosis of acute or subacute adrenal hematoma and myelolipoma. Hematomas are round to oval and have increased attenuation (50-90 HU) that decreases on follow-up CT scans. Myelolipomas typically manifest as a well-defined suprarenal mass with an attenuation of-30 to -115 HU. Adrenal cysts are usually round to oval and manifest as a hypoattenuating mass with a smooth, thin wall. CT is useful in the evaluation of patients with Addison disease, particularly the subacute form secondary to tuberculosis or disseminated histoplasmosis. Findings typically include bilateral adrenal enlargement with a central necrotic area of hypoattenuation and peripheral enhancement. Thin-section unenhanced CT permits accurate measurement of attenuation and can be used to differentiate adrenal adenoma from metastasis in a cancer patient with an indeterminate mass: Attenuation of 10 HU or less usually indicates adenoma rather than cancer. If the mass is found incidentally at contrast material-enhanced CT, delayed scans obtained as early as 5-15 minutes after intravenous administration of contrast material appear to have comparable accuracy.

BACKGROUND: The symptom burden of intensive care unit (ICU) patients who are referred to a palliative care team (PCT) has not been characterized to the authors' knowledge, and the response of these symptoms to the palliative care intervention has not been reported. METHODS: The authors retrospectively reviewed PCT consults for ICU patients who were seen between July 2006 and October 2007. To characterize symptom distress and outcomes in ICU patients who were referred to PCT in a cancer center, information and descriptive statistics about patients' demographics, comorbidities, PCT findings, interventions, and outcomes were obtained. The chi-square test was used to analyze ICU and PCT mortality, and the signed-rank test was used to analyze PCT interventions. RESULTS: Of 1637 PCT consults, 88 consults (5%) were from the ICU. The median patient age was 60 years (range, 22-87 years), and 41 patients (46%) were women. The types of cancers were hematologic (19 patients; 22%), gastrointestinal (19 patients; 22%), lung (18 patients; 20%), and others (24 patients; 26%). Nineteen patients were on mechanical ventilation (MV), and 24 patients were on bilevel positive airway pressure (BIPAP). The findings were delirium (71 patients; 81%), dyspnea (67 patients; 76%), pain (74 patients; 84%), fatigue (84 patients; 95%), and anxiety (57 patients; 65%). The interventions used were opioid management (99%), steroids (70%), antipsychotics (76%), and counseling (100%), do not resuscitate conversion (62 of 88 patients; 70%), withdrawal of MV (15 of 19 patients; 79%), and withdrawal of BIPAP (26 of 26 patients; 100%). Improvement was reported in pain (67 patients; 90%), dyspnea (60 patients; 90%), anxiety (51 patients; 80%), and delirium (31 patients; 44%). Thirty-five patients (40%) were transferred to the palliative care unit (PCU). Fifty-one ICU/PCT patients (58%) died during admission versus 130 of 1549 (8%) non-ICU PCT patients (P<.0001). Twenty-three of 35 patients who were transferred to the PCU (66%) died there versus 212 of 629 patients (34%) who were admitted to the PCU from another service (P<.0001). Thirty-seven of 88 ICU/PCT patients (42%) were discharged alive. CONCLUSIONS: ICU patients who are referred to the PCT have severe symptom distress. The PCT was able to identify multiple problems and make numerous pharmacologic and nonpharmacologic recommendations that improved these symptoms, including the participation in do not resuscitate conversion and withdrawal of MV and BIPAP. Although many patients in this population died, a significant subset, including those who were transferred to the PCU, survived to discharge.

OBJECTIVE: To assess the utility of triage guidelines for patients with cholelithiasis and suspected choledocholithiasis, incorporating selective use of magnetic resonance cholangiography (MRC) and endoscopic retrograde cholangiopancreatography (ERCP) before laparoscopic cholecystectomy (LC). SUMMARY BACKGROUND DATA: ERCP is the most frequently used modality for the diagnosis and resolution of choledocholithiasis before LC. MRC has recently emerged as an accurate, noninvasive modality for the detection of choledocholithiasis. However, useful strategies for implementing this diagnostic modality for patient evaluation before LC have not been investigated. METHODS: During a 16-month period, the authors prospectively evaluated all patients before LC using triage guidelines incorporating patient information obtained from clinical evaluation, serum chemistry analysis, and abdominal ultrasonography. Patients were then assigned to one of four groups based on the level of suspicion for choledocholithiasis (group I, extremely high; group 2, high; group 3, moderate; group 4, low). Group 1 patients underwent ERCP and clearance of common bile duct stones; group 2 patients underwent MRC; group 3 patients underwent LC with intraoperative cholangiography; and group 4 patients underwent LC without intraoperative cholangiography. RESULTS: Choledocholithiasis was detected in 43 of 440 patients (9.8%). The occurrence of choledocholithiasis among patients in the four groups were 92.6% (25/27), 32.4% (12/37), 3.8% (2/52), and 0.9% (3/324) for groups 1, 2, 3, and 4, respectively (P <.001). MRC was used for 8.4% (37/440) of patients. Patient triage resulted in the identification of common bile duct stones during preoperative ERCP in 92.3% (36/39) of the patients. Unsuspected common bile duct stones occurred in six patients (1.4%). CONCLUSIONS: The probability of choledocholithiasis can be accurately assessed based on information obtained during the initial noninvasive evaluation. Stratification of risks for choledocholithiasis facilitates patient management with the most appropriate diagnostic studies and interventions, thereby improving patient care and resource utilization.

PURPOSE: To determine whether HERV-K envelope (ENV) protein could function as a tumor-associated antigen and elicit specific T-cell responses against autologous ovarian cancer cells. EXPERIMENTAL DESIGN: The expression of HERV-K transcripts and ENV protein, the presence of serum antibodies against HERV-K, reverse transcriptase (RT) activities, and cellular immune responses in primary ovarian cancer tissues and patient blood samples were analyzed and compared with samples from patients with benign ovarian diseases and normal female donors. RESULTS: Ovarian cancer cells in primary tumors and ascites expressed markers of cancer stem cells and markers of both mesenchymal and epithelial cells. Expression of HERV transcripts and HERV-K ENV protein and reverse transcriptase activities were higher in ovarian cancer compared with adjacent normal and benign tissues. The ovarian cancer patient plasma also had high reverse transcriptase activities and the ovarian cancer patient sera contained HERV-K immunoreactive antibodies. HERV-K-specific T cells generated from autologous dendritic cells pulsed with HERV-K ENV antigens exhibited phenotypes and functions consistent with a cellular immune response including T-cell proliferation, IFNγ production, and HERV-K-specific cytotoxic T lymphocyte (CTL) activity. Significantly higher CTL lysis of autologous tumor cells than of uninvolved normal cells was demonstrated in patients with ovarian cancer than patients with benign diseases and further enhanced lysis was observed if T regulatory cells were depleted. CONCLUSION: Endogenous retroviral gene products in ovarian cancer may represent a potentially valuable new pool of tumor-associated antigens for targeting of therapeutic vaccines to ovarian cancer.

This article explores the history of the preconception movement in the United States and the current status of professional practice guidelines and standards. Professionals with varying backgrounds (nurses, nurse practitioners, family practice physicians, pediatricians, nurse midwives, obstetricians/gynecologists) are in a position to provide preconception health services; standards and guidelines for numerous professional organizations, therefore, are explored. The professional nursing organization with the most highly developed preconception health standards is the American Academy of Nurse Midwives (ACNM); for physicians, it is the American College of Obstetricians and Gynecologists (ACOG). These guidelines and standards are discussed in detail.

The aims of this study were to examine differences in self-schemas between persons living with HIV/AIDS with and without depressive symptoms, and the degree to which these self-schemas predict depressive symptoms in this population. Self-schemas are beliefs about oneself and include self-esteem, HIV symptom management self-efficacy, and self-compassion. Beck's cognitive theory of depression guided the analysis of data from a sample of 1766 PLHIV from the USA and Puerto Rico. Sixty-five percent of the sample reported depressive symptoms. These symptoms were significantly (p ≤ 0.05), negatively correlated with age (r = -0.154), education (r = -0.106), work status (r = -0.132), income adequacy (r = -0.204, self-esteem (r = -0.617), HIV symptom self-efficacy (r = - 0.408), and self-kindness (r = - 0.284); they were significantly, positively correlated with gender (female/transgender) (r = 0.061), white or Hispanic race/ethnicity (r = 0.047) and self-judgment (r = 0.600). Fifty-one percent of the variance (F = 177.530 (df = 1524); p < 0.001) in depressive symptoms was predicted by the combination of age, education, work status, income adequacy, self-esteem, HIV symptom self-efficacy, and self-judgment. The strongest predictor of depressive symptoms was self-judgment. Results lend support to Beck's theory that those with negative self-schemas are more vulnerable to depression and suggest that clinicians should evaluate PLHIV for negative self-schemas. Tailored interventions for the treatment of depressive symptoms in PLHIV should be tested and future studies should evaluate whether alterations in negative self-schemas are the mechanism of action of these interventions and establish causality in the treatment of depressive symptoms in PLHIV.

Transvaginal sonography is a highly sensitive method for detecting endometrial thickening. In the postmenopausal woman such thickening is non-specific and can be due to hyperplasia, polyps, submucosal endoluminal fibroids, or carcinoma. In such cases, transvaginal sonography combined with transvaginal hysterosonography may assist in the workup of these endometrial processes. We compared the combination of transvaginal sonography and transvaginal hysterosonography to aspiration endometrial biopsy in the evaluation of women with postmenopausal bleeding. We prospectively performed transvaginal sonography in 148 women within 1 month (range, 10 days to 2 months) after having had an aspiration endometrial biopsy. Transvaginal hysterosonography was then performed in 81 of these women who had endometrial thickness greater than 5 mm. In these 81 patients, transvaginal hysterosonography confirmed 45 lesions: 23 pedunculated endometrial masses and 22 inhomogeneous sessile lesions. Women with positive transvaginal hysterosonography examinations then underwent hysteroscopy or hysterectomy, whereas women with negative examinations were followed conservatively. Forty-one of the 45 cases with endoluminal masses on transvaginal hysterosonography had false-negative aspiration biopsies. Of the five (11%) lesions that were malignant, three resulted in false-negative biopsies, one biopsy revealed hyperplasia, and only one biopsy was true positive. All 36 women with negative transvaginal hysterosonography examinations also had negative biopsy findings. We conclude that the combination of transvaginal sonography and transvaginal hysterosonography is more sensitive in the detection of endometrial pathologic lesions than is endometrial biopsy, and that transvaginal sonography or transvaginal hysterosonography should be included in the evaluation of women with postmenopausal bleeding.

OBJECTIVES: This study investigates how health- and disability-based need factors and enabling factors (e.g., socioeconomic and family-based resources) relate to nursing home admission among 3 different racial and ethnic groups. METHOD: We use Cox proportional hazard models to estimate differences in nursing home admission for non-Hispanic whites, non-Hispanic blacks, and Hispanics from 1998 to 2010 in the Health and Retirement Study (N = 18,952). RESULTS: Racial-ethnic differences in nursing home admission are magnified after controlling for health- and disability-based need factors and enabling factors. Additionally, the degree to which specific factors contribute to risk of nursing home admission varies significantly across racial-ethnic groups. DISCUSSION: Our findings indicate that substantial racial and ethnic variations in nursing home admission continue to exist and that Hispanic use is particularly low. We argue that these differences may demonstrate a significant underuse of nursing homes for racial and ethnic minorities. Alternatively, they could signify different preferences for nursing home care, perhaps due to unmeasured cultural factors or structural obstacles.

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are associated with a high mortality rate; however, there is no uniform way to categorize the severity of this disease early in its course. The goal of this study was to develop a clinical score based on data available at the time of initial assessment to aid in stratifying patients according to their risk of death. METHODS: A cohort of all 350 patients admitted with NSTI to two institutions over a nine-year period was examined retrospectively. Using random split sampling, two datasets were created: Prediction (PD) and validation (VD). Multivariable stepwise regression analysis of the PD identified independent predictors of death using data available at the time of admission. Model performance was evaluated for accuracy, discrimination, and calibration. A clinical score to predict death was created, and using the Trauma and Injury Severity Score (TRISS) methodology, the score was validated on the VD (z-statistic). RESULTS: Six admission parameters independently predicted death: Age > 50 years, heart rate > 110 beats/min, temperature <36 degrees C, white blood cell count > 40,000/mcL, serum creatinine concentration > 1.5 mg/dL, and hematocrit > 50%. The accuracy of this model was 86.8%; the area under the receiver-operating characteristic curve was 0.81, and the Hosmer-Lemeshow statistic was 11.8. Additionally, the score had excellent performance in evaluation on the VD (z-score/statistic 0.23 to - 0.83). CONCLUSION: A clinical score that categorizes patients with NSTI according to the risk of death was created. It uses simple variables, all available at the time of first assessment. It stratifies patients according to disease severity and can guide the use of aggressive or novel therapeutic strategies and selection of patients for clinical trials.
