Successful pregnancy after tamoxifen and megestrol acetate therapy for endometrial carcinoma

A 31 year old woman presented in August 1991, and her main complaint was of primary infertility and menorrhagia which she had had for two years. Her basal body temperature record showed an anovulatory pattern. She was of average stature and did not appear malnourished. No hirsutism was noted. Hormone profiles including plasma oestradiol, testosterone, prolactin, follicle stimulating hormone, luteinising hormone, diurnal cortisol and thyroid function tests were normal. Hysterosalpingography showed filling defects in the endometrial cavity and confirmed bilateral tuba1 patency. A hysteroscopic examination was performed, anticipating demonstration of a submucosal leiomyoma or endometrial polyp. Multiple endometrial polypoid masses were biopsied via the hysteroscope, followed by endometrial curettage. The histology report identified a welldifferentiated adenocarcinoma of the endometrium (Fig. 1).
Ascent of Dinosaurs Linked to an Iridium Anomaly at the Triassic-Jurassic Boundary

Analysis of tetrapod footprints and skeletal material from more than 70 localities in eastern North America shows that large theropod dinosaurs appeared less than 10,000 years after the Triassic-Jurassic boundary and less than 30,000 years after the last Triassic taxa, synchronous with a terrestrial mass extinction. This extraordinary turnover is associated with an iridium anomaly (up to 285 parts per trillion, with an average maximum of 141 parts per trillion) and a fern spore spike, suggesting that a bolide impact was the cause. Eastern North American dinosaurian diversity reached a stable maximum less than 100,000 years after the boundary, marking the establishment of dinosaur-dominated communities that prevailed for the next 135 million years.
Addressing research capacity for health equity and the social determinants of health in three African countries: the INTREC programme

Background The importance of tackling economic, social and health-related inequities is increasingly accepted as a core concern for the post-Millennium Development Goal framework. However, there is a global dearth of high-quality, policy-relevant and actionable data on inequities within populations, which means that development solutions seldom focus on the people who need them most. INTREC (INDEPTH Training and Research Centres of Excellence) was established with this concern in mind. It aims to provide training for researchers from the INDEPTH network on associations between health inequities, the social determinants of health (SDH), and health outcomes, and on presenting their findings in a usable form to policy makers. Objective As part of a baseline situation analysis for INTREC, this paper assesses the current status of SDH training in three of the African INTREC countries – Ghana, Tanzania, and South Africa – as well as the gaps, barriers, and opportunities for training. Methods SDH-related courses from the three countries were identified through personal knowledge of the researchers, supplemented by snowballing and online searches. Interviews were also conducted with, among others, academics engaged in SDH and public health training in order to provide context and complementary material. Information regarding access to the Internet, as a possible INTREC teaching medium, was gathered in each country through online searches. Results SDH-relevant training is available, but 1) the number of places available for students is limited; 2) the training tends to be public-health-oriented rather than inclusive of the broader, multi-sectoral issues associated with SDH; and 3) insufficient funding places limitations on both students and on the training institutions themselves, thereby affecting participation and quality. We also identified rapidly expanding Internet connectivity in all three countries, which opens up opportunities for e-learning on SDH, though the current quality of the Internet services remains mixed. Conclusions SDH training is currently in short supply, and there is a clear role for INTREC to contribute to the training of a critical mass of African researchers on the topic. This work will be accomplished most effectively by building on pre-existing networks, institutions, and methods.
Tuning of the visual word processing system: Distinct developmental ERP and fMRI effects

Visual tuning for words vs. symbol strings yields complementary increases of fast occipito‐temporal activity (N1 or N170) in the event‐related potential (ERP), and posterior–anterior gradients of increasing word‐specific activity with functional magnetic resonance imaging (fMRI) in the visual word form system (VWFS). However, correlation of these coarse ERP and fMRI tuning responses seems limited to the most anterior part of the VWFS in adult and adolescent readers (Brem et al. [ 2006 ]: Neuroimage 29:822–837). We thus focused on fMRI tuning gradients of young readers with their more pronounced ERP print tuning, and compared developmental aspects of ERP and fMRI response tuning in the VWFS. Children (10.3 y, n = 19), adolescents (16.2 y, n = 13) and adults (25.2 y, n = 18) were tested with the same implicit reading paradigm using counterbalanced ERP and fMRI imaging. The word‐specific occipito‐temporal N1 specialization, its corresponding source activity, as well as the integrated source activity (0–700 ms) were most prominent in children and showed a marked decrease with age. The posterior–anterior fMRI gradient of word‐specific activity instead which was fully established in children did not develop further, but exhibited a dependence on reading skills independent of age. To conclude, prominent developmental dissociation of the ERP and fMRI tuning patterns emerged despite convergent VWFS localization. The ERP response may selectively reflect fast visual aspects of print specialization, which become less important with age, while the fMRI response seems dominated by integrated task‐ and reading‐related activations in the same regions.

Perceived intent motivates people to magnify observed harms

Significance This paper examines how detecting harmful intent creates downstream consequences for assessing damage, magnifying its cost. If intentional harms seem worse, society may spend more money on them than on objectively more damaging unintentional harms or on naturally occurring harms. Why might this occur? Various psychological theories identify the cause as motivation; however, the presence of this motivation has been inferred indirectly. Drawing on animal-model research, we present more direct evidence for blame motivation, and discuss how it may help to explain the magnification of intentional harms. This approach acknowledges the nonrational biases in damage estimates and potential policy priorities. Existing moral psychology research commonly explains certain phenomena in terms of a motivation to blame. However, this motivation is not measured directly, but rather is inferred from other measures, such as participants’ judgments of an agent’s blameworthiness. The present paper introduces new methods for assessing this theoretically important motivation, using tools drawn from animal-model research. We test these methods in the context of recent “harm-magnification” research, which shows that people often overestimate the damage caused by intentional (versus unintentional) harms. A preliminary experiment exemplifies this work and also rules out an alternative explanation for earlier harm-magnification results. Exp. 1 asks whether intended harm motivates blame or merely demonstrates the actor’s intrinsic blameworthiness. Consistent with a motivational interpretation, participants freely chose blaming, condemning, and punishing over other appealing tasks in an intentional-harm condition, compared with an unintentional-harm condition. Exp. 2 also measures motivation but with converging indicators of persistence (effort, rate, and duration) in blaming. In addition to their methodological contribution, these studies also illuminate people’s motivational responses to intentional harms. Perceived intent emerges as catalyzing a motivated social cognitive process related to social prediction and control.
Carcinogenetic impact of ADH1B and ALDH2 genes on squamous cell carcinoma risk of the esophagus with regard to the consumption of alcohol, tobacco and betel quid

The consumption of alcohol, tobacco and betel quid has been found to be an important contributor to esophageal squamous cell carcinoma (ESCC) in Taiwan. The genotoxic effect of the ADH1B and ALDH2 genes modulating an individual's alcohol‐metabolizing capacity on ESCC may be linked to drinking behavior, intake pattern and other exogenous factors. To investigate the interplay of these genetic and environmental factors in determining the risk of ESCC, a multicenter case‐control study was conducted. Here, 406 patients with pathology‐proven ESCC, as well as 656 gender, age and study hospital matched controls were recruited. Genetic polymorphisms of ADH1B and ALDH2 appeared to correlate with the abstinence of alcohol, though not with tobacco and betel quid. Within the same levels of alcohol consumption, carcinoma risks increased along with an increase in the numbers of ADH1B*1 and ALDH2*2 alleles. The inactive ALDH2*1/*2 genotype was found to multiplicatively interact with a low‐to‐moderate (0.1–30 g/day) and a heavy (>30 g/day) ethanol intake to increase the ESCC risk (the joint aOR = 14.5 and 102.6, respectively). Among low‐to‐moderate drinkers, a smoking‐dependent carcinogenetic effect for the ADH1B*1/*1 and ALDH2*1/*2+*2/*2 genotypes was recognized, with significant risks found in smokers, but not in nonsmokers. Further, a supra‐multiplicative combined risk of ESCC for alcohol and tobacco use was identified among carriers of the ADH1B*1/*1 genotype (p for interaction = 0.042). In conclusion, the interplay of the ADH1B and ALDH2 genotypes, in conjunction with a behaved drinking habit and a practiced drinking pattern, along with continued tobacco consumption, plays an important pathogenic role in modulating ESCC risk. © 2007 Wiley‐Liss, Inc.
Specific Interaction of Hepatitis C Virus Protease/Helicase NS3 with the 3′-Terminal Sequences of Viral Positive- and Negative-Strand RNA

ABSTRACT The hepatitis C virus (HCV)-encoded protease/helicase NS3 is likely to be involved in viral RNA replication. We have expressed and purified recombinant NS3 (protease and helicase domains) and ΔpNS3 (helicase domain only) and examined their abilities to interact with the 3′-terminal sequence of both positive and negative strands of HCV RNA. These regions of RNA were chosen because initiation of RNA synthesis is likely to occur at or near the 3′ untranslated region (UTR). The results presented here demonstrate that NS3 (and ΔpNS3) interacts efficiently and specifically with the 3′-terminal sequences of both positive- and negative-strand RNA but not with the corresponding complementary 5′-terminal RNA sequences. The interaction of NS3 with the 3′-terminal negative strand [called 3′(−) UTR127] was specific in that only homologous (and not heterologous) RNA competed efficiently in the binding reaction. A predicted stem-loop structure present at the 3′ terminus (nucleotides 5 to 20 from the 3′ end) of the negative-strand RNA appears to be important for NS3 binding to the negative-strand UTR. Deletion of the stem-loop structure almost totally impaired NS3 (and ΔpNS3) binding. Additional mutagenesis showed that three G-C pairs within the stem were critical for helicase-RNA interaction. The data presented here also suggested that both a double-stranded structure and the 3′-proximal guanosine residues in the stem were important determinants of protein binding. In contrast to the relatively stringent requirement for 3′(−) UTR binding, specific interaction of NS3 (or ΔpNS3) with the 3′-terminal sequences of the positive-strand RNA [3′(+) UTR] appears to require the entire 3′(+) UTR of HCV. Deletion of either the 98-nucleotide 3′-terminal conserved region or the 5′ half sequence containing the variable region and the poly(U) and/or poly(UC) stretch significantly impaired RNA-protein interaction. The implication of NS3 binding to the 3′-terminal sequences of viral positive- and negative-strand RNA in viral replication is discussed.
Listeriosis in pregnancy: survey of British Columbia practitioners' knowledge of risk factors, counseling practices, and learning needs.

OBJECTIVE To determine the knowledge, counseling practices, and learning needs of practitioners in British Columbia regarding risk factors for listeriosis in pregnancy. DESIGN A 1-page, mailed, self-administered, anonymous questionnaire. SETTING British Columbia. PARTICIPANTS A total of 827 practitioners (614 family physicians, 93 midwives, and 120 family practice residents) were sent the questionnaire. MAIN OUTCOME MEASURES Awareness of listeriosis, knowledge of the risk factors for listeriosis, practices for counseling pregnant women, practitioners' learning needs, and provider and practice characteristics. RESULTS A total of 340 practitioners (41%) completed the questionnaire. While most (88%) physicians and midwives had heard of listeriosis, few (18%) were aware that infection was more common during pregnancy. One-third (33%) of practitioners counseled pregnant women about the risk factors for listeriosis. The main reasons for not providing such counseling were lack of knowledge and the perception that listeriosis was rare and not an important concern for pregnant women. Rates of counseling were highest among midwives (84%) and lowest among physicians practising outside the Lower Mainland of British Columbia (12%). Of those practitioners providing prenatal care, 47% counseled pregnant women about the risks of unpasteurized milk and 41% counseled women about the risks of consuming soft cheese; few counseled about the risks of consuming deli meat or raw hot dogs (25%), unwashed fruit and vegetables (12%), or refrigerated smoked seafood (6%). CONCLUSION Most prenatal care providers in British Columbia are unaware of the risk factors for listeriosis or its propensity for pregnant women and do not counsel their pregnant patients about these risks.
Quantitation of Absolute Pneumocystis carinii Nuclear DNA Content. Trophic and Cystic Forms Isolated from Infected Rat Lungs are Haploid Organisms

The Pneumocystis carinii carinii DNA content in nuclei of trophic forms and cysts (spore cases) containing 2, 4, or 8 intracystic bodies, were compared using quantitative fluorescence image analysis. The nuclear DNA content was found to be lower than the theoretical limits of Feulgen cytophotometry. Several fluorescent DNA dyes provide brighter staining, but these techniques suffer from nonspecific binding to other cellular components, such as RNA. It was demonstrated that the thick glycocalyx surfaces of trophic forms and the cyst walls of P. carinii organisms, as well as the cell wall of S. cerevisiae, bound all fluorescent dyes tested to varying degrees. Hence in this study, measurements were performed on cells in which the outer surfaces of organisms were first removed with lyticase. Two stains that appeared most specific for DNA, DB181 and 4′,6‐diamidino‐2‐phenylindole (DAPI), were used for quantitations; lower deviations of fluorescence intensities were observed with DB181. Haploid wild type Saccharomyces cerevisiae and cdc‐28 temperature‐sensitive mutant cells, accumulated at the restrictive temperature (37° C), were used as quantitative internal standards for estimating the absolute nuclear DNA content of P. carinii. Haploid wild type and mutant nuclei stained with DAPI had the same relative fluorescence intensities. The P. carinii nuclear DNA content of trophic forms and individual intracystic bodies (spores), regardless of life cycle stage, were not different. The mean values obtained were 6.9 and 6.7 fg DNA/nucleus with DB181 and DAPI, respectively (approximately 9.26 and 8.99 Mbp nucleotides, respectively). Since these would include 2C (G‐2 phase) and S‐phase nuclei, a 1C population of nuclei was selected by histogram distributions of DB181‐stained nuclei. Almost all nuclei analyzed in all life cycle stages fell within this population. The 1C mean of 6.55 fg DNA/nucleus (median, 6.62 fg DNA/nucleus) was estimated as representing 8.79 Mbp nucleotides, assuming only A‐T binding of the dye and taking into account the G+C content of S. cerevisiae and P. carinii. A 4C (G‐2‐phase diploid nuclei) population was not detected in histograms of DB181‐ or DAPI‐stained nuclei. The P. carinii nuclear DNA content values obtained in this study were similar to those independently obtained by calculating the total DNA in the organism's chromosomes resolved by electrophoretic techniques. Together, the data on total chromosome numbers and the estimated DNA content of those chromosomes, with our quantitation of nuclear DNA content of different life‐cycle stages demonstrate that P. carinii carinii isolated from infected rat lungs are haploid organisms.
Adverse childhood experiences and adult risk factors for age-related disease: depression, inflammation, and clustering of metabolic risk markers.

OBJECTIVE To understand why children exposed to adverse psychosocial experiences are at elevated risk for age-related disease, such as cardiovascular disease, by testing whether adverse childhood experiences predict enduring abnormalities in stress-sensitive biological systems, namely, the nervous, immune, and endocrine/metabolic systems. DESIGN A 32-year prospective longitudinal study of a representative birth cohort. SETTING New Zealand. PARTICIPANTS A total of 1037 members of the Dunedin Multidisciplinary Health and Development Study. Main Exposures During their first decade of life, study members were assessed for exposure to 3 adverse psychosocial experiences: socioeconomic disadvantage, maltreatment, and social isolation. MAIN OUTCOME MEASURES At age 32 years, study members were assessed for the presence of 3 age-related-disease risks: major depression, high inflammation levels (high-sensitivity C-reactive protein level >3 mg/L), and the clustering of metabolic risk biomarkers (overweight, high blood pressure, high total cholesterol, low high-density lipoprotein cholesterol, high glycated hemoglobin, and low maximum oxygen consumption levels. RESULTS Children exposed to adverse psychosocial experiences were at elevated risk of depression, high inflammation levels, and clustering of metabolic risk markers. Children who had experienced socioeconomic disadvantage (incidence rate ratio, 1.89; 95% confidence interval, 1.36-2.62), maltreatment (1.81; 1.38-2.38), or social isolation (1.87; 1.38-2.51) had elevated age-related-disease risks in adulthood. The effects of adverse childhood experiences on age-related-disease risks in adulthood were nonredundant, cumulative, and independent of the influence of established developmental and concurrent risk factors. CONCLUSIONS Children exposed to adverse psychosocial experiences have enduring emotional, immune, and metabolic abnormalities that contribute to explaining their elevated risk for age-related disease. The promotion of healthy psychosocial experiences for children is a necessary and potentially cost-effective target for the prevention of age-related disease.
Implementation strategies for collaborative primary care-mental health models

Purpose of review Extensive research exists that collaborative primary care-mental health models can improve care and outcomes for patients. These programs are currently being implemented throughout the United States and beyond. The purpose of this study is to review the literature and to generate an overview of strategies currently used to implement such models in daily practice. Recent findings Six overlapping strategies to implement collaborative primary care-mental health models were described in 18 selected studies. We identified interactive educational strategies, quality improvement change processes, technological support tools, stakeholder engagement in the design and execution of implementation plans, organizational changes in terms of expanding the task of nurses and financial strategies such as additional collaboration fees and pay for performance incentives. Summary Considering the overwhelming evidence about the effectiveness of primary care-mental health models, there is a lack of good studies focusing on their implementation strategies. In practice, these strategies are multifaceted and locally defined, as a result of intensive and required stakeholder engagement. Although many barriers still exist, the implementation of collaborative models could have a chance to succeed in the United States, where new service delivery and payment models, such as the Patient-Centered Medical Home, the Health Home and the Accountable Care Organization, are being promoted.
Applying the Chronic Care Model to Support Ostomy Self-Management: Implications for Oncology Nursing Practice.

BACKGROUND Living with an ostomy requires daily site and equipment care, lifestyle changes, emotional management, and social role adjustments. The Chronic Care Ostomy Self-Management Training Program (CCOSMTP) offers an ostomy self-management curriculum, emphasizing problem solving, self-efficacy, cognitive reframing, and goal setting. OBJECTIVES The qualitative method of content analysis was employed to categorize self-reported goals of ostomates identified during a nurse-led feasibility trial testing the CCOSMTP. METHODS Thirty-eight ostomates identified goals at three CCOSMTP sessions. The goals were classified according to the City of Hope Health-Related Qualify of Life Model, a validated multidimensional framework, describing physical, psychological, social, and spiritual ostomy-related effects. Nurse experts coded the goals independently and then collaborated to reach 100% consensus on the goals' classification. FINDINGS A total of 118 goals were identified by 38 participants. Eighty-seven goals were physical, related to the care of the skin, placement of the pouch or bag, and management of leaks; 26 were social goals, which addressed engagement in social or recreational roles and daily activities; and 5 were psychological goals, which were related to confidence and controlling negative thinking. Although the goals of survivors of cancer with an ostomy are variable, physical goals are most common in self-management training.
