JCO: Editorial - Ovarian Suppression for Prevention of Premature Menopause and Infertility: Empty Promise or Effective Therapy? (in Breast Cancer) see note/your comments?
Blogger's Note: compared with other young cancer survivors??
~~~~~~~~~~~~~
"Fertility and premature menopause are major concerns for young patients who are undergoing treatment for cancer. Young women with breast cancer face particular challenges when considering future fertility compared with other young cancer survivors.1 The greatest concern is whether preservation of ovarian function and a subsequent pregnancy in a breast cancer survivor could increase the risk of recurrence, particularly in patients with hormone receptor–positive disease....."

Editorial: Full-text - The Use of Sedation in Palliative Care
| "....Often pain and suffering make it difficult for patients themselves to participate, further reducing their autonomy and empowerment. Patients should be kept fully empowered by being thoroughly informed of all means available to reduce their symptoms and maximize their comfort at the earliest possible stage of their palliative care." |
| "Dying patients in palliative care settings deserve to have maximum control over their futures. This includes full disclosure on the use and effectiveness of sedation for palliative ends. Allowing patients more decision-making power in choosing various levels of sedation through to CDS would significantly improve the dying process while maintaining ethically sound practices as viewed by all parties concerned. Health care practitioners would not have to feel that they are hastening death. Patients would have greater control over their symptoms. Family members would not have to watch their loved ones endure dysteleological suffering. It is the best we can do when facing our finitude, and dying patients deserve our best." |
Editorial: Full-text - For a Modern Concept of Palliative Care
"Unfortunately, in most countries hospice care addresses end-of-life care."
"....This late referral to palliative care is also in contrast with the classical definition of palliative care provided by WHO: “Palliative care is ….. applicable early in the course of illness, in conjunction with other therapies that are intended to prolong life, such as chemotherapy or radiation therapy, and includes those investigations needed to better understand and manage distressing clinical complications” [6].

abstract: Palliative Medicine Fellowship: A Study of Resident Choices
Context
There are no data on the motives or characteristics of physicians choosing fellowship training in Hospice and Palliative Medicine (HPM).
Objectives
To understand more about the residents who choose HPM and what leads them to this decision.
Conclusion
Negative experiences with end-of-life care in residency, particularly in the intensive care unit, continue to be a factor in selection of HPM as a specialty. Many residents make their decision to enter the field and apply during Postgraduate Year 3. Most received negative comments about the choice. Fellows require a broad range of experience when selecting a fellowship program.
abstract: Does public disclosure of quality indicators influence hospitals' inclination to enhance results? (using Oesophageal resection as the example)
CONCLUSION:
Our results support the assumption that low-volume hospitals are inclined to adjust their numbers when, because outcomes are public, pressure to report a sufficient number is high. So, external verification of data is essential when this 'need to score' is high.Systematic Reviews - Why prospective registration of systematic reviews makes sense
Abstract (provisional)
Prospective registration of systematic reviews promotes transparency, helps reduce potential for bias and serves to avoid unintended duplication of reviews. Registration offers advantages to many stakeholders in return for modest additional effort from the researchers registering their reviews.

abstract: How valid are claims for synergy in published clinical studies?
Abstract
Background: Clinical trials evaluating drug combinations are often stimulated by claims of synergistic interactions in preclinical models. Overuse or misuse of the term synergy could lead to poorly designed clinical studies.
Conclusions: Synergy is cited frequently in phase I and phase II studies to justify the evaluation of a specific drug combination. Inappropriate methods for evaluation of synergy and poor assessment of therapeutic index have been used in most preclinical articles.

EVOLVING ETHICS
Sexually transmitted diseases (STDs) were a prime concern for health officials in the 1940s, and many medical studies — including the US experiments in Guatemala — used methods that would be considered unethical today.

UK survey - young adults - : When do life crises strike? Help us find out (online 20 min survey)
When do life crises strike? Help us find out
Psychologist Dan Levinson once remarked that he had never met anyone who had not gone through at least one major crisis during their adult life.
While films, sports-car cliches and personal experience may back up his comment, the questions of when and for whom crises occur have received little academic attention. Well, not for much longer.
Last year, New Scientist reported on the phenomenon of the quarter-life crisis; the re-evaluation and dramatic change of direction that sometimes occurs during early adulthood.
This was based on research carried out by researchers at the University of Greenwich who interviewed 50 young people about their emotional experiences during this time. The work established that the quarter-life crisis exists (as corroborated by the comments on our news story) but the sample wasn't large enough to determine how common it is or when it occurs.
Now, the innermost secrets of the crisis are to be laid bare. The Greenwich team are conducting an online survey of British adults which will probe the link between crisis episodes, age and life stage across a diverse group of adults.
The researchers are looking for adult volunteers to participate in the study. You can take part here (and be in with the chance of winning a cash prize for your efforts).
Stay tuned as New Scientist will exclusively report the findings later this year.
~~~~~~~~~~~~~~
What does it involve and how long does it take?
The online questionnaire will involve approximately 20 minutes of your time.You will be asked for the following information:
- Age, job, income, marital status and number of children.
- Crisis episodes and turning points in your adult life (if you are currently aged 25 or above)
- Your marital satisfaction (if you are married)
- Your sense of happiness, life satisfaction and wellbeing
- Your sense of empathy
Who can participate?
In order to participate, you must be age 20 or over, have lived in the UK for the majority of your life since the age of 15 and be able to read and write English fluently.

"As a PhD student, learning to navigate the murky waters of collaboration and competition is pretty confusing........But many labs continue to jealously guard their progress and sacrifice paper quality for personal recognition. Should such egotism be acceptable in science, the main aims of which are, ideally, discovery and innovation, rather than accolades for its practitioners? As a young researcher, I am puzzled that a community reliant on integrity and transparency is tolerant of lies and misdirection in the publications race....."
abstract: (in mice) MEK1/2 Inhibitor Selumetinib (AZD6244) Inhibits Growth of Ovarian Clear Cell Carcinoma in a PEA-15–Dependent Manner in a Mouse Xenograft Model
Blogger's Note: in research (mice)
Abstract
Clear cell carcinoma (CCC) of the ovary tends to show resistance to standard chemotherapy, which results in poor survival for patients with CCC. Developing a novel therapeutic strategy is imperative to improve patient prognosis. Epidermal growth factor receptor (EGFR) is frequently expressed in epithelial ovarian cancer. One of the major downstream targets of the EGFR signaling cascade is extracellular signal–related kinase (ERK). PEA-15, a 15-kDa phosphoprotein, can sequester ERK in the cytoplasm. MEK1/2 plays a central role in integrating mitogenic signals into the ERK pathway. We tested the hypothesis that inhibition of the EGFR–ERK pathway suppresses tumorigenicity in CCC, and we investigated the role of PEA-15 in ERK-targeted therapy in CCC. We screened a panel of 4 CCC cell lines (RMG-I, SMOV-2, OVTOKO, and KOC-7c) and observed that the EGFR tyrosine kinase inhibitor erlotinib inhibited cell proliferation of EGFR-overexpressing CCC cell lines through partial dependence on the MEK/ERK pathway. Furthermore, erlotinib-sensitive cell lines were also sensitive to the MEK inhibitor selumetinib (AZD6244), which is under clinical development. Knockdown of PEA-15 expression resulted in reversal of selumetinib-sensitive cells to resistant cells, implying that PEA-15 contributes to selumetinib sensitivity. Both selumetinib and erlotinib significantly suppressed tumor growth (P < 0.0001) in a CCC xenograft model.However, selumetinib was better tolerated; erlotinib-treated mice exhibited significant toxic effects (marked weight loss and severe skin peeling) at high doses. Our findings indicate that the MEK–ERK pathway is a potential target for EGFR-overexpressing CCC and indicate that selumetinib and erlotinib are worth exploring as therapeutic agents for CCC.

Radiotherapeutic and surgical management for newly diagnosed brain metastasis/es: An American Society for Radiation Oncology evidence-based guideline (2012)
Read the guideline.
This guideline provides guidance for patients and physicians regarding the following key clinical questions: What prognostic factors are important for assessing and managing patients with newly diagnosed brain metastases; for patients with single brain metastasis (excluding radiosensitive histologies such as small cell lung cancer, leukemia, lymphoma and germ cell tumor), does surgical resection and whole brain radiotherapy improve survival or brain control compared with whole brain radiotherapy alone or surgical resection alone; is survival or brain control different in selected patients with single brain metastasis (excluding radiosensitive histologies such as small cell lung cancer, leukemia, lymphoma and germ cell tumor) treated with surgery or radiosurgery; is there a survival or brain control difference in patients treated with WBRT and radiosurgery boost versus WBRT alone; is there a difference in survival, brain control or neurocognitive outcomes in patients treated with radiosurgery alone versus WBRT and radiosurgery; what is the role of comfort measures or palliative supportive care alone versus WBRT in patients with multiple brain metastases; what is the optimal WBRT dose fractionation schedule; what is the role of radiosensitizers with WBRT in the management of patients with brain metastases; and what is the role of chemotherapy and WBRT?

abstract: Microparticles From Ovarian Carcinomas Are Shed Into Ascites and Promote Cell Migration (EpCAM/assay/benign ascites/small study)
Abstract
Objective: Microparticles are cellular-derived vesicles (0.5-1.0 [mu]m) composed of cell membrane components, which are actively shed from the surface of various cells, including epithelial cells. We compared microparticles in ascites between women with ovarian carcinoma and women with benign ovarian pathology, and isolated tumor-derived (epithelial cell adhesion molecule [EpCAM]-positive) microparticles for functional analysis and proteomics.
Results: Microparticles in benign pelvic fluid were similar to early and advanced-stage ascites (2.4 vs 2.8 vs 2.0 x 106 microparticles/mL). Advanced stage had a greater proportion of EpCAM-positive microparticles than early or benign disease (13.3% vs 2.5% vs 2.1%; P = 0.001), and serous histology had more than endometrioid (13.2% vs 1.8%; P = 0.01).......Conclusions: Ascites from advanced-stage and serous ovarian carcinomas contain large numbers of tumor-derived microparticles. In vitro, these microparticles bind to cancer cells and stimulate migration. Tumor-derived microparticles in ascites could mediate the predilection for peritoneal spread in serous ovarian carcinomas.

"... Most US hospitals are accredited by the Joint Commission and many are certified by the American College of Surgery Commission on Cancer. To date, these bodies have not focused attention on the safety of patients who are receiving chemotherapy.
The modified ASCO/ONS Chemotherapy Administration
Safety Standards serve as a call-to-action to these organizations.
We encourage medical oncologists to bring the standards to the

"For more than a decade, patients and their oncologists have been sharing conversations about cognitive complaints after chemotherapy treatment.1 Early on, only occasional patients complained of trouble with concentration and memory during treatment, with a minority noting persistence beyond the end of treatment. The oncologist, who rarely heard this complaint, could be dismissive, saying that the drugs the patient received did not cross the blood-brain barrier, and therefore, it was unlikely that the difficulties were related to the cancer treatment. Post-treatment cognitive complaints became much more evident during the late 1990s and early 21st century as adjuvant treatment regimens intensified and autologous bone marrow transplantation became more common in adults.2,3 ......."

open access: Pharmaceutical care for patients with breast and ovarian cancer - adverse drug events
Blogger's Note: 'tag' line includes breast cancer only; study included few ovarian cancer patients
Conclusions
In conclusion, our results suggest that
pharmaceutical care for patients with breast and ovarian cancer is
feasible and may
have an impact on PROs as particularly indicated by
significant improvements of the antiemetic response and patient
satisfaction.
Although there is no doubt that a higher awareness of
drug-related problems is beneficial, final conclusions on the
effectiveness
of a new health care intervention can only be drawn when
studied in a randomized trial. Therefore, our data may serve as a
valuable basis for planning a large randomized
multicenter trial.

Anti-inflammatory Phytochemicals
In conclusion, results from many published studies described above indicate a definitive involvement of inflammation pathway in the progression and treatment of ovarian cancer. Some anti-inflammatory phytochemicals exhibit the activities to intervene the dysregulated inflammation pathway, and may play a beneficial role in the treatment of advanced EOC. However, there are many questions remain to be answered. Further research in this area is urgently needed.
Evidence Updates: Antibiotic prophylaxis for bacterial infections in afebrile neutropenic patients following chemotherapy. Cochrane Database Syst Rev includes professional commentaries
AUTHORS' CONCLUSIONS:
Antibiotic prophylaxis in afebrile neutropenic patients significantly reduced all-cause mortality.
In our review, the most significant reduction in mortality was observed in trials assessing prophylaxis with quinolones. The benefits of antibiotic prophylaxis outweighed the harm such as adverse effects and the development of resistance since all-cause mortality was reduced. As most trials in our review were of patients with haematologic cancer, we strongly recommend antibiotic prophylaxis for these patients, preferably with a quinolone.
Prophylaxis may also be considered for patients with solid tumours or lymphoma.

abstract: Predictive value of serum CA-125 levels in patients with persistent or recurrent epithelial ovarian cancer or peritoneal cancer treated with Bevacizumab (Avastin) Gynecologic Oncology Group phase II trial
Purpose
To compare two methods of determining therapeutic response and disease progression — modified Gynecologic Cancer Intergroup (GCIG) criteria based on CA-125 and Radiographic Evaluation Criteria in Solid Tumors (RECIST), in a phase II trial of bevacizumab for patients with recurrent or persistent epithelial ovarian and peritoneal carcinoma.
Results
Sixty-two patients were evaluable by RECIST, 59 for progression by CA-125, and 45 for response by CA-125..........
Conclusions
In this study, disease assessment by RECIST and CA-125 appears to correlate in general. However, approximately 10% of patients might demonstrate progression earlier by CA-125.
Highlights
► CA125-defined response and progression were assessed for women with recurrent ovarian cancer.
► CA125 and RECIST-defined response and progression correlated in most cases, but CA125 progression significantly preceded RECIST in 8 cases.
► CA125-defined response to bevacizumab was associated with a statistically significant correlation with overall survival.
► CA125 and RECIST-defined response and progression correlated in most cases, but CA125 progression significantly preceded RECIST in 8 cases.
► CA125-defined response to bevacizumab was associated with a statistically significant correlation with overall survival.
abstract: A systematic review of sexual concerns reported by gynecological cancer survivors
Conclusion
Gynecological cancer survivors experience a broad range of sexual concerns after diagnosis and treatment, but the majority of studies emphasized physical aspects of sexuality, and may not adequately represent women's psychological and social sexual concerns. Health care providers should remain mindful of psychological and social sexual concerns when caring for gynecologic cancer survivors. Future research should systematically evaluate the full range of sexual concerns in large, representative samples of GYN cancer survivors and develop and test interventions to address those concerns.
Highlights
► Literature focuses on physical sexual dysfunction in gynecologic cancer survivors.
► Women report range of sexual concerns: physical, psychological, social.
► Research should include comprehensive/systematic assessment of sexual concerns.
► Women report range of sexual concerns: physical, psychological, social.
► Research should include comprehensive/systematic assessment of sexual concerns.

abstract: Informational needs of gynecologic cancer survivors
Abstract:
Objectives
In preparation for the launch of a gynecologic oncology survivorship program, this study looked at the informational needs of women with gynecologic cancers. Although studies have touched on some of these needs, no published literature has investigated the comprehensive informational needs of gynecologic oncology patients within all sites of gynecologic cancers.
Methods
A needs assessment, consisting of a self-administered questionnaire, was conducted at an ambulatory gynecologic oncology clinic from August 2010 to March 2011. This study investigated the informational needs of patients, including the importance of information, the amount desired, and the preferred mode of delivery. Informational needs were grouped into six domains: medical, practical, physical, emotional, social, and spiritual.
Results
185 surveys were analyzed and the majority of the respondents were Caucasian (77%) and over the age of 50 (66%). Forty-nine percent of respondents were diagnosed with ovarian cancer, and there was an even distribution between newly diagnosed patients (38%), those in long-term follow-up (27%), and those with recurrent disease (37%). Overall, respondents placed more importance on receiving medical information (P < 0.01). The three preferred education modalities were; pamphlets, one-on-one discussions with health care professionals and websites. Age, education, and disease site were associated with differing informational needs.
Conclusions
This study has highlighted the most important informational needs of patients with gynecologic malignancies in our patient population. This information may guide the development of clinical survivorship programs and educational resources for patients in the future.
Highlights
► We report the results of a needs assessment that was done to better understand the informational needs of gynecologic cancer survivors.
► Increasing responsiveness to survivor needs can greatly affect health outcomes and patient satisfaction.
► We did this to launch a gynecologic cancer survivorship program that is responsive to survivor needs.
► Increasing responsiveness to survivor needs can greatly affect health outcomes and patient satisfaction.

Hormone therapy for menopausal symptoms | BMJ
A recently published and much publicised paper by Shapiro and colleagues, the last in a series of four, evaluated the effects of hormone therapy on the risk of breast cancer.1
The authors of the four review articles applied epidemiological principles to the findings of two randomised placebo controlled studies from the Women’s Health Initiative (WHI; 27 347 women) and two observational studies—the Collaborative Reanalysis (53 865 women) and the Million Women Study (MWS). Shapiro and colleagues concluded in their fourth paper that the MWS had design defects, that it contained multiple biases, and that its findings were thus not robust enough to show that hormone therapy increased the risk of breast cancer.
All observational studies are inherently biased because subjects are not randomly assigned to treatment or control. Adjustment for confounders and careful design of observational studies help to reduce bias. However, because there is no independent variable, such studies can tell us only about association not causation.
The MWS was published in the Lancet in August 2003,2 and a flurry of letters was published in a print issue later that year, many …"

Therefore, we believe that the conclusion of this meta-analysis should be that structured exercise training is associated with clinically important positive effects on physical functions and quality of life in patients who had completed their treatment for cancer.
Whether and to what extent these interventions will also increase daily physical activity levels in cancer survivors remains currently unknown.

Radiation Oncology A National Survey of the Availability of Intensity-Modulated Radiation Therapy and Stereotactic Radiosurgery in Canada
Blogger's Note: no references to 'ovarian'/'ovary'/'gyn'
Conclusions
The survey showed a growing adoption of IMRT and SRS in Canada, although the latter was available in less than half of responding centers. Barriers to implementation differed for IMRT compared to SRS. Enhancing human resources is an important consideration in the implementation of new RT technologies, due to the multidisciplinary nature of the planning and treatment process.

abstract: From "Sex Toy" to Intrusive Imposition: A Qualitative Examination of Women's Experiences with Vaginal Dilator Use Following Treatment for Gynecological Cancer.
Abstract
Introduction. Regular use of vaginal dilators has been recommended as a prophylactic measure following radiation treatment for gynecological cancer....Aim. To investigate women's experiences with the vaginal dilator and to understand the psychosocial factors that influence women's adoption of rehabilitative dilator use.
Results. The analysis resulted in five main categories underlying the core category of "From 'Sex Toy' to Intrusive Imposition." These were: (i) embarrassing sex toy; (ii) reliving the invasion of treatment; (iii) aversive "hands-on" experience; (iv) not at the forefront of my recovery; and (v) minimizing the resistance.
Conclusions. Rehabilitative vaginal dilator use is a complex, multifaceted, and personal phenomenon that carries deep psychological and emotional implications that make it intrusive.

open access: Impact of remuneration and organizational factors on completing preventive manoeuvres in primary care practices
Blogger's Note: note patient numbers per physician; study limitations

"Primary care providers are increasingly interested in ensuring that preventive health care be part of their work routines.1 This reorientation fits with the evidence that recommendations from family practitioners increase substantially the likelihood of patients undergoing preventive manoeuvres,2 whereas the lack of such recommendations has been linked with patient noncompliance.3,4
Studies evaluating adherence to recommended preventive care suggest that the most pervasive barriers rest with the organization of the health care system and the practice itself, such as the absence of external financial incentives for the work done and the lack of a reminder system in the office.3,5–9

Metastases from other solid organ primaries
"Breast cancer is the most common type of primary malignancy
in women, but metastatic spread to the breast from other solid
organs, although rare, has been reported 51–53 and may be the
first sign of malignancy.54..."
~~~~~~~~~~~~~~~~~~~
Abstract: Although much emphasis has been placed on the primary presentations of breast cancer, little focus has been placed on how systemic illnesses may affect the breast. In this article, we discuss systemic illnesses that can manifest in the breast. We summarize the clinical features, imaging, histopathology, and treatment recommendations for endocrine, vascular, systemic inflammatory, infectious, and hematologic diseases, as well as for the extramammary malignancies that can present in the breast. Despite the rarity of these manifestations of systemic disease, knowledge of these conditions is critical to the appropriate evaluation and treatment of patients presenting with breast symptoms.

Abstract
Ovarian carcinoma can be subdivided into two categories termed type I and type II. Type I tumours, usually having an indolent clinical behaviour, are often detected in early stage, and rarely harbour p53 gene mutations. Each histological type has a distinct molecular profile with mutations of genes involved in different signalling transduction pathways, such as KRAS, BRAF, CTNNB1, PTEN, PIK3CA and ARID1A. Type II tumours, accounting for 75% of the cases, have a very aggressive biological behaviour, are usually in advanced stage at presentation, harbour p53 gene mutations in 80% of the cases, and sometimes have alterations of homologous recombination (HR). Both type I and type II tumours arise from extra-ovarian precursors. Serous carcinomas derive from tubal epithelium, endometrioid and clear cell carcinomas from endometrial tissue, and mucinous and Brenner tumours from transitional epithelial cells located near the tubo-peritoneal junction. These new concepts on the pathogenesis of ovarian carcinoma could deeply modify both the preventive approach in women with germ-line BRCA(1) or BRCA(2) mutations and the treatment of patients with advanced or recurrent disease. For instance, BRAF inhibitors could be used in low-grade serous carcinomas, PIK3CA inhibitors could be employed in clear cell carcinoma, and poly (ADP-ribose) polymerase inhibitors could be used not only in hereditary ovarian carcinoma but also in non-hereditary, high-grade serous ovarian carcinoma which sometimes shows defective HR.

Comparative effectiveness research plan seeks input from all sides (including patients/families) deadline March 15th ... American Medical News
"PCORI leaders want feedback from patients, caregivers, clinicians and others on its research agenda. They want to know if the tentative agenda covers key subjects for which more evidence-based information is needed, said Eugene Washington, MD, MSc, PCORI's board chair and dean of the David Geffen School of Medicine at the University of California Los Angeles. The leaders also want to involve patients in a significant way in the research process, according to PCORI Executive Director Joe Selby, MD, MPH. "This initial agenda does not limit which conditions or treatments will be studied. It is a starting point," he said, adding that 2012 "will be a year of engagement."".........
Also: "The 53-day public comment period, which will end March 15, will be used to solicit feedback and revise the priorities and agenda before a final version of each is adopted by PCORI's Board of Governors."
abstract: Effects of vitamin E on bone turnover markers among US postmenopausal women.
Abstract
Increased oxidative stress and inflammation resulting from aging and declining estrogen levels can lead to increased bone loss in postmenopausal women. Alpha- and gamma-tocopherol, the two predominant isomers of vitamin E, have antioxidant and anti-inflammatory properties, but their effects on bone metabolism have not been well studied in humans. We examined the associations between dietary and total (diet and supplements) alpha-tocopherol intake, serum alpha- and gamma-tocopherol levels and their ratio, and bone turnover markers (BTMs) among postmenopausal women aged ≥45 years........Women of Teal: Cancer Support Community Website Relaunch

Researchers Find Ovarian Cancer Risk Related To Inherited Inflammation Genes - newswise
"... The authors noted that in 2011 there were an estimated 225,500 new cases of ovarian cancer worldwide. Although some women are at greatly elevated risks of ovarian cancer due to inherited mutations in the BRCA1 and BRCA2 genes (and Lynch Syndrome amongst other rarer syndomes), these are rare in the population and account for perhaps 10 percent of cases. However, a substantial portion of genetic influence on ovarian cancer risk has been “unexplained” and some of that may be due to common genetic variants. Sellers points out that “the Il1A variant that was most strongly protective is carried by 30 percent of women in the study, so the impact at the population level is not trivial.”

CONCLUSIONS:
The combination of veliparib with metronomic cyclophosphamide is well tolerated and shows promising activity in a subset of patients with BRCA mutations. A phase II trial of the combination compared to single-agent cyclophosphamide is ongoing in BRCA-positive ovarian cancer, triple-negative breast cancer, and low-grade lymphoma.open access: Chinese Medical Journal - Evaluation of whether serum tumor markers in patients with epithelial ovarian carcinoma change following chemotherapy

Vignette-Based Study of Ovarian Cancer Screening: Do U.S. Physicians Report Adhering to Evidence-Based Recommendations?
Abstract
"Background: No professional society or group recommends routine ovarian cancer screening, yet physicians' enthusiasm for several cancer screening tests before benefit has been proven suggests that some women may be exposed to potential harms.
Objective: To provide nationally representative estimates of physicians' reported nonadherence to recommendations against ovarian cancer screening.
Design: Cross-sectional survey of physicians offering women's primary care. The 12-page questionnaire contained a woman's annual examination vignette and questions about offers or orders for transvaginal ultrasonography (TVU) and cancer antigen 125 (CA-125).........."

Web resource helps assess life expectancy - - ModernMedicine website: ePrognosis.org
Blogger's Note:
“Not everything that can be counted counts and not everything that counts can be counted.” Albert Einstein
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"A set of prognostic indices used to calculate a patient’s life expectancy has been created and posted on a new Web site.
The site, www.ePrognosis.org, was created in conjunction with a review of these assessments that was published in JAMA (2012; 307:182-92). That study concluded that the most accurate and usable indices might have value when used in conjunction with other clinical information.
Many medical interventions, including those for urologic and other cancers, have guidelines recommending that physicians take a patient’s life expectancy into account, said senior investigator Alexander K. Smith, MD, MPH, of the University of California, San Francisco. "Given this goal, it would be ideal if there were one index that would allow you to plug in your patient’s information—age, diseases, functional impairments—and get an accurate long-term prognosis.
"Unfortunately, there is not. In the absence of that, we have this systematic review and corresponding online compendium, which we hope physicians will find a useful adjunct, along with patient preferences and their own professional judgments, in making clinical decisions that involve life expectancy," Dr. Smith said........

New website: NIH Clinical Research Trials and You
Agency-wide resource provides important information for the public and health care providers
The National Institutes of Health has created a new website, NIH Clinical Research Trials and You to help people learn more about clinical trials, why they matter, and how to participate. From the first cure of a solid tumor with chemotherapy to the use of nitroglycerin in response to heart attacks, clinical research trials — or research studies involving people — have played a vital role in improving health and quality of life for people around the globe.Clinical trials are essential for identifying and understanding ways to prevent, diagnose, and treat disease. Research has shown that among the greatest challenges to recruitment of volunteers is the lack of general knowledge about what trials involve, where they are carried out, and who may participate.
"The ability to recruit the necessary number of volunteers is vital to carrying out clinical research that leads to health and medical advances," said NIH Director Francis S. Collins, M.D., Ph.D. "This new, centralized resource will make it much easier for the public and health professionals to learn about clinical trials and how people can participate in them."
Visitors to the website will find information about:
- The basics of clinical trial participation
- First hand experiences from actual clinical trial volunteers
- Explanations from researchers
- Links on how to search for a trial or enroll in a research matching program
NIH supports clinical research trials across the country and throughout the world. NIH’s ongoing effort to raise awareness about clinical research and educate potential clinical trial participants about the option of a clinical trial is vital to developing public support and understanding for how clinical research drives medical discovery and improves health outcomes.
About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S. Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research, and is investigating the causes, treatments, and cures for both common and rare diseases.

Medscape: The Case for Retaining Bereavement Exclusion
"....
"The evidence suggests that the excluded episodes are best considered a normal variation in bereavement and not a mental disorder," he added.
Reflection Advisable
In an accompanying editorial, Mario Maj, MD, PhD, of the Department of Psychiatry, University of Naples, Italy, and chairperson of the World Health Organization Working Group on the Classification of Mood and Anxiety Disorders, concludes that the removal of the BE from the diagnosis of major depressive episode can only be justified by "strong and unequivocal new research evidence. Wakefield and First's review...suggests that such a solid and consistent new evidence is not available."
"Further reflection," Dr. Maj writes, "seems therefore warranted before proceeding with the deletion of the bereavement exclusion.".....

abstract: Adjuvant Analgesics in Cancer Pain: A Review
"Adjuvant analgesics (co-analgesics) are medications whose primary indication is the management of a medical condition with secondary effects of analgesia (pain killer). Cancer pain is multifactorial and often involves inflammatory, nociceptive, and neuropathic pain subtypes. Adjuvant analgesics used in conjunction with opioids have been found to be beneficial in the management of many cancer pain syndromes; however, they are currently underutilized. Antidepressants, anticonvulsants, local anesthetics, topical agents, steroids, bisphosphonates, and calcitonin are all adjuvants which have been shown to be effective in the management of cancer pain syndromes. When utilizing analgesic adjuvants in the treatment of cancer pain, providers must take into account the particular side effect profile of the medication. Ideally, adjuvant analgesics will be initiated at lower dosages and escalated as tolerated until efficacy or adverse effects are encountered."

abstract: The Pattern of Antimicrobial Use for Palliative Care In-Patients During the Last Week of Life
Background: In terminally ill cancer patients approaching the dying phase, liberal use of antimicrobials is often viewed by palliative care experts as irrational. No previous reports have reviewed current antimicrobial use in palliative care settings in Saudi Arabia.
Objective: The objective of this study was to explore the pattern of antimicrobial use in a tertiary palliative care unit (TPCU) during the last week of patients’ life.
Methods: Medical records of all patients who died in the TPCU over a 14-month period were reviewed for demographics as well as the frequency and rationale of antimicrobial use during the patients’ last week of life. Information on antimicrobial use was obtained from a computerized pharmacy database.
Results: Of 138 patients who died with advanced cancer in the TPCU, 87 (63%) were on one or more antimicrobials during their last week of life. Antibiotics were more frequently used as compared to antifungal and antiviral agents, 64 (46.4%); 45 (32.6%); and 2 (1.5%), respectively. About one third (31.3%) of patients who received antibiotics during their last week of life were prescribed more than one antibiotic. Antimicrobials were mostly given systemically (79%) rather than topically (21%). The most common rationales for antimicrobial prescribing were oral thrush in 36 patients (25.4%), wound care in 29 patients (20.4%), and on empirical basis in 29 patients (20.4%).
Conclusions: The current practice of antimicrobial prescribing, especially for patients who are eminently dying, may need to be reviewed. Initiation of antimicrobial treatment in this group of patients should be based on clear treatment goals and desired outcomes, considering views of patients and families.
abstract: End-of-Life Care at an Academic Medical Center
"Background: End-of-life care is deemed to be poor in the United States – particularly in large teaching hospitals. Via a brief survey, we examined satisfaction with end-of-life care for those patients who died in our academic medical center from provider and family perspectives.
Methods: To assess the correlation between overall satisfaction between providers (attending, housestaff, and nurses) as well as family members for decedents who died in our hospital, we conducted a satisfaction survey regarding care in the last three days of life. The nine item survey was administered within 1 week of the patient s death to care providers and approximately 8 to 12 weeks to next of kin.
Results: There were 166 deaths examined over the four month study period. Overall satisfaction with care was 3.02 out of 4.0, and differed by respondent group (p= 0.035). Correlation between respondents was very low (range 0.02 to 0.51). The least discordance was between residents and interns (0.5), who had the lowest level of satisfaction (2.72). Housestaff and attendings had the lowest overall correlation in mean satisfaction scores (0.05). Most providers knew their patients for 24 hours or less.
Conclusions: Overall satisfaction was high, but there was discordance among different providers. Continuity of care was limited. Age and location of death alone did not significantly affect satisfaction with end-of-life care. Implications of this type of research for improving end of life care at academic centers are discussed."

abstract: A Qualitative Study of Family Involvement in Decisions About Life Support in the Intensive Care Unit
"We explored family involvement in decisions about life support interventions in the intensive care unit study using a critical incident technique to focus on specific case exemplars contributed by participants. A total of 6 family members and 9 health care professionals were interviewed. Participants described 2 options (life support or comfort care) and values associated with options: maintaining quality of life, surviving critical illness, minimizing pain and suffering, not being attached to machines, needing adjustment time, and judicious health care resource use. Barriers to involvement included not being offered alternative options; no specific trigger to initiate decision making; dominant influence of professionals’ values; and families lacking understandable information. Family members are unlikely to engage in decision making unless professionals identify the decision and address other barriers to family involvement."

"The test will require FDA approval before it can move beyond clinical testing.Pathologists and oncologists already have a test, called CellSearch, that’s used to look for CTCs (circulating tumor cells). But Kuhn says physicians need a test that is far more sensitive, and thus more useful for a wide array of cancer patients."

abstract: Importance of Histologic Subtype in the Staging of Appendiceal Tumors
Blogger's Note: appendiceal cancer (cancer of the appendix) is not the only cancer where cell type histologic records are deficient eg. breast cancer; why it's important? many reasons: patients with dual malignancies, primary vs metastatic, borderline/invasive.....; as in ovarian cancer cell, type/s are included in one's own individual pathology report/s
Abstract
Background
Malignant neoplasms of the appendix have different behavior based on their histologic subtypes in anecdotal series. Current staging systems do not capture the diversity of histologic subtypes in predicting outcomes.

Abstract
Registry based cancer incidence and mortality data are widely used for etiologic research, cancer control and health care monitoring and planning. The complete coverage of all cases is the key criteria of data quality but it is difficult to assess because the alternative sources of data may be flawed. ..........
..........In conclusion, some 10% of cancer deaths had no cancer records in CR (cancer registry) or in HDR (hospital discharge registry), and 3.4% were missing in both sources. The identification rate depended on tumor site, age at death, and, to some extent, death outside hospital.
