The iatrogenesis of obstetric racism in Brazil: beyond the body, beyond the clinic.

In Brazil, Black women are disproportionately denied access to timely care and are made vulnerable to death by avoidable obstetric causes. However, they have not been at the center of recent initiatives to improve maternal health. This paper contends that the effectiveness of Brazilian maternal and infant health policy is limited by failures to robustly address racial health inequities. Multi-sited ethnographic research on the implementation of the Rede Cegonha program in Bahia, Brazil between 2012 and 2017 reveals how anti-Blackness structures iatrogenic harms for Black women as well as their kin in maternal healthcare. Building on the work of Black Brazilian feminists, the paper shows how Afro-Brazilian women experience anti-Black racism in obstetric care, which the paper argues can be better understood through Dána-Ain Davis' concept of obstetric racism. The paper suggests that such forms of violence reveal the necropolitical facets of reproductive governance and that the framing of obstetric violence broadens the scales and temporalities of iatrogenesis.

Expectations of therapeutic radiography students in Wales about transitioning to practice during the Covid-19 pandemic as registrants on the HCPC temporary register.

INTRODUCTION: The Covid-19 crisis continues to profoundly impact on radiotherapy practice in the UK. We explore the views of therapeutic radiographer students on entering their first post in unique circumstances as a means to evaluate the support that may minimise negative impacts on their transition to practitioners. METHOD: Focus groups were conducted outside of students' final year educational programme and immediately prior to them starting work. Qualitative data were analysed using a framework analysis. RESULTS: Emergent themes from the eleven participants were: Covid-19 as a layer on top of underlying anxieties; Degree of readiness for imminent psychological, emotional and practical challenges; Feeling valued as a health professional/radiographer at this time; A mixed student and qualified staff professional identity as HCPC temporary registrants. CONCLUSION: Uncertainties related to Covid-19 were seen to add a destabilising component to existing anxieties and challenges. In this context, there are significant risks of impaired professional socialisation due to incongruence between students' expectations and the reality in clinical departments. IMPLICATIONS FOR PRACTICE: Informed academic support and flexible clinical preceptorship that address anxieties and congruence barriers are vital to guide new practitioners through a health crisis that presents significant challenges but also opportunity for professional development.

Interventive Care: Uncertainty, Distributed Agency, and Cesarean Section in a Zika Virus Epidemic.

Beginning in 2015, Brazil witnessed the births of thousands of children with neurological abnormalities linked to the Zika virus. Drawing on ethnographic fieldwork conducted between 2016 and 2018 with parents of children with congenital Zika syndrome in Salvador da Bahia, this article attends to how one of Brazil's most overused obstetric technologies-cesarean section-was mobilized to mitigate the uncertainties of Zika's reproductive consequences. I argue that during the epidemic, C-section constituted a form of what I call interventive care, in which others interceded on behalf of pregnant women to secure surgical delivery. In dialogue with scholarship problematizing autonomy in reproductive decision making, I show how my Bahian interlocutors understood such intercessions, and the C-sections themselves, as forms of appropriate, concerned care. I suggest, furthermore, that interventive care highlights the ways in which reproductive decisions are distributed among people rather than autonomous, particularly in contexts of heightened uncertainty.

Hendra in the Hunter Valley.

In June 2019 the first equine case of Hendra virus in the Hunter Valley, New South Wales, Australia was detected. An urgent human and animal health response took place, involving biosecurity measures, contact tracing, promotion of equine vaccinations and investigation of flying fox activity in the area. No human or additional animal cases occurred. Equine vaccination uptake increased by over 30-fold in the surrounding region in the three months following the case. Black flying fox and grey-headed flying fox species were detected in the Valley. The incident prompted review of Hendra virus resources at local and national levels. This event near the "horse capital of Australia", is the southernmost known equine Hendra case. Management of the event was facilitated by interagency collaboration involving human and animal health experts. Ongoing One Health partnerships are essential for successful responses to future zoonotic events.

The radiology impact of healthcare errors during shift work.

OBJECTIVES: What are the risks of error as a result of out-of-hours work in health care that could be attributed to Shift Work Disorder; and what safety implications would this have for radiographers working with ionising radiation? To conduct a literature search of existing studies of Shift Work Disorder. To critically appraise appropriate studies for research rigour. To synthesize and discuss findings in the selected research articles. To investigate the impact of the results in relation to medical imaging and safety. KEY FINDINGS: A systematic review of the literature was planned and executed to meet the above objectives. Narrative synthesis was used to describe the heterogeneous findings of the studies appraised. CONCLUSION: Four of the five studies selected after critical appraisal suggested a positive correlation of error with increased mental and physical fatigue as a result of shift work or rapid shift rotation. No studies directly investigated medical imaging professionals. IMPLICATION FOR PRACTICE: Considerations need to be made when optimising shift work for healthcare professionals so as to avoid Shift Work Disorder and consequential error; particularly in the context of ionising radiation. Research into environmental and lifestyle support should be pursued to study its effect as prevention or management. Further direct study with radiographers is recommended.

Cuidado nos tempos de Zika: notas da pós-epidemia em Salvador (Bahia), Brasil / El cuidado en tiempos del Zika: notas de la post-epidemia en Salvador (Bahia), Brasil / Care in the time of Zika: notes on the 'afterlife' of the epidemic in Salvador (Bahia), Brazil

Este artigo traz uma reflexão sobre a pós-epidemia do vírus Zika por meio das narrativas de mães de crianças nascidas com más-formações neurológicas associadas ao vírus na Bahia. A partir de 11 entrevistas semiestruturadas com mães e pais cujos filhos fazem atendimento em um centro de referência estadual em reabilitação e em diálogo com teorizações contemporâneas de tempo e deficiência na antropologia cultural, propõe-se uma abordagem à temporalidade do Zika vírus e aos seus efeitos. São destacadas três falas, demostrando como a condição imprevisível dos filhos, junto com as precariedades que já vivenciam, fazem com que o futuro seja algo quase impossível de imaginar. Destaca-se que, diante de tamanha incerteza, as mães criam formas alternativas de pensar sobre, interagir com e valorizar a criança nos seus próprios termos. Sugere-se que a esperança pode incluir, paradoxalmente, "não esperar nada".(AU)

Este artículo presenta una reflexión sobre la post-epidemia del virus del Zika por medio de las narraciones de madres de niños nacidos con malformaciones neurológicas asociadas al virus en Bahia. A partir de once entrevistas semi-estructuradas con madres y padres cuyos hijos reciben atención en un centro de referencia del estado en rehabilitación y en diálogo con teorizaciones contemporáneas de tiempo y deficiencia en la antropología cultural, se propone un abordaje a la temporalidad del Zika y a sus efectos. Se destacan tres diálogos, demostrando cómo la condición imprevisible de los hijos, juntamente con las precariedades que ya viven, hacen que el futuro sea algo casi imposible de imaginar. Se subraya que, ante tanta incertidumbre, las madres crean formas alternativas de pensar sobre el niño e a interactuar con él en sus propios términos. Se sugiere que la esperanza puede incluir paradójicamente el "no esperar nada".(AU)

This article presents a reflection on the "afterlife" of the Zika virus epidemic, drawing on the narratives of mothers of children born with neurological malformations associated with the virus in Bahia. Based on eleven semi-structured interviews with mothers and fathers whose children are attended in a state rehabilitation center, and in dialogue with contemporary theorizations of time and disability in cultural anthropology, it proposes an approach to the temporality of Zika and its effects. Three narratives are highlighted, showing how their children's unpredictable condition, together with the precarities they already experience, make the future almost impossible to imagine. In the face of so much uncertainty, mothers create alternative forms of thinking about, interacting with, and appreciating the child in her or his own terms. This article suggests that hope may include, paradoxically, "expecting nothing".(AU)

Microbial evaluation of automated sorting systems in stone fruit packinghouses during peach packing.

Automated fruit sorting systems with individual fruit carriers are utilized in modern fruit packing facilities. This study evaluated the levels of naturally occurring microflora on the surfaces of peaches and fruit carriers during automated sorting operations at stone fruit packinghouses in California. The study also assessed the growth potential of Salmonella enterica and Listeria monocytogenes on fruit carriers under various environmental conditions. No difference of microbial loads was found on peaches (n = 420) before, during, and after fruit sorting at seven packinghouses. The average surface total microbial, coliform, and yeast and mold levels of peaches during sorting were 3.6, 2.7, and 1.9 log CFU/cm2, respectively. Environmental swab testing indicated routine cleaning of fruit carriers (n = 192) reduced total microbes from 3.9 to 3.2 log CFU/cm2 (P = 0.003) and coliforms from 1.5 to 0.9 log CFU/cm2 (P = 0.001) on carriers' fruit contact surfaces. Laboratory exposures to temperature (22, 28, 34 or 40 °C) and humidity (65, 75, 85 or 95%) conditions significantly reduced inoculated Salmonella and Listeria on clean and commercially used (deposited with wax, fuzz, dirt, etc.) fruit carriers within 24 h (P < 0.001). The observed Salmonella reduction was greater on clean carriers (P < 0.001). On used carriers, Salmonella was persistent at 95% humidity and Listeria was persistent at 22 °C. The results showed the levels of surface microflora on peaches during fruit sorting, the reduction of microbial loads on fruit carriers due to packinghouses' cleaning, and the reduction, rather than growth, of Salmonella and Listeria under tested conditions on fruit carriers.

Factors Associated with Pre-Event Hydration Status and Drinking Behavior of Middle-Aged Cyclists.

OBJECTIVES: Water is an essential nutrient for thermoregulation, metabolism, cognition, and overall physiological homeostatic function. However, aging adults display a blunted thirst mechanism and subsequently have an increased risk for dehydration or hyponatremia. Fluid consumption behaviors are modifiable and the importance of practicing adequate drinking behaviors for aging adults is amplified during exercise. Identification of aging adult's hydration beliefs and how they attain hydration advice could provide valuable information into ways to promote better drinking habits to reduce fluid imbalances. Thus, this investigation evaluated the knowledge, beliefs and behaviors of middle-aged cyclists (MA) that were associated with hydration status and drinking behavior, before and during a 164-km mass-participation event (ambient temperature, 33.3±2.8ºC(mean±SD)). DESIGN: This cross-sectional field study retrospectively grouped participants by their second urine specific gravity (Usg) measurement of the event morning prior to a mass participation cycling event. Usg was assessed via handheld refractometer. SETTING: The Hotter N' Hell Hundred 164-km cycling event in Wichita Falls, Texas during the month of August. PARTICIPANTS: 36 male recreational cyclists (age, 53±9 y(mean±SD)). MEASUREMENTS: Participants were grouped according their urine specific gravity as either slightly hyperhydrated (SH; n=12, Usg≤1.014), euhydrated (EUH; n=12, Usg, 1.015-1.020), or slightly dehydrated (SD; n=12, Usg≥1.021). Exercise histories and questionnaires were recorded 24-48 h prior to the cycling event. RESULTS: Regardless of pre-event hydration status, all groups experienced a similar body mass loss during the 164-km event and finished with statistically similar exercise times; also, drinking behavior within all groups was influenced by multiple factors. The primary factors associated with MA cyclist drinking behavior were trial and error/personal history and thirst; further, the majority of cyclists (≥65%) in SH, EUH, and SD believed that dehydration affects performance negatively. The least important factors included rehydration recommendations from scientific and sports medicine organizations, plus information from sports drink manufacturers. CONCLUSION: Considering the complexity of the present findings and the physiological changes that accompany aging such as delayed thirst perception, we recommend that MA cyclists formulate an individualized drinking plan that is based on observations during exercise.

Natural antibody responses to Plasmodium falciparum MSP3 and GLURP(R0) antigens are associated with low parasite densities in malaria patients living in the Central Region of Ghana.

BACKGROUND: Plasmodium falciparum genetic diversity and multiplicity of infection (MOI) are parasite features that have been suggested to influence the acquisition of protective immunity against malaria. This study sought to assess the relationship between MOI and parasite density (PD) in malaria patients living in the Central Region of Ghana and to determine whether naturally occurring antibody levels against P. falciparum GLURP (PF3D7_1035300) and MSP3 (PF3D7_1035400) antigens are associated with decreased parasite load. METHODS: Dried filter paper blood blots were obtained from children and adults diagnosed with uncomplicated P. falciparum malaria. Microscopy was used to estimate P. falciparum parasite density and polymerase chain reaction (PCR) amplification of the polymorphic regions of msp1 (PF3D7_0930300) and msp2 (PF3D7_0206800) was used for parasite genotyping and MOI determination. ELISA was used to measure the serum IgG concentration of R0 fragment of GLURP (GLURP(R0)) and MSP3 antibodies. RESULTS: All 115 samples were positive for P. falciparum by PCR using either the msp1 or msp2 genotyping primer sets. The most prevalent msp1 and msp2 alleles were KI and 3D7, respectively. The geometric mean (GM) for MOI determined by both msp1 and msp2 genotyping was 1.3 for the entire population and was generally higher in children than in adults. Seropositivity was estimated at 67 and 63% for GLURP(R0) and MSP3 antibodies, respectively, and antibody titers were negatively correlated with parasite density. CONCLUSIONS: The negative correlation between naturally occurring GLURP(R0) and MSP3 antibody levels and parasite density observed in this study suggest that augmenting the antibody response with the GMZ2 vaccine could enhance protection in the Central Region of Ghana.

Safety and efficacy of high-dose enteral, intravenous, and transdermal clonidine for the acute management of severe intractable childhood dystonia and status dystonicus: An illustrative case-series.

OBJECTIVE: Acute dystonia in children is distressing, painful and can progress to life-threatening status dystonicus. Typical management involves benzodiazepines which can result in respiratory depression requiring PICU admission. Clonidine is less respiratory-depressant, and by facilitating sleep, switches dystonia off. It can also be administered via enteral, continuous intravenous infusion, and transdermal slow release routes. We describe the dose range and safety profile of clonidine management in a case-series of children with severe acute exacerbation of dystonia in a tertiary hospital setting. METHODS: The management of 5 children (3 female, age range 8-14 years) suffering from an acute exacerbation of secondary dystonia requiring hospital admission at the Evelina London Children's Hospital was reviewed. The average and maximum dose of clonidine in mcg/kg/h and routes of administration were recorded for each day of hospital admission. Co-administration of any other medical treatments for dystonia and their route of administration were also recorded. Cardiovascular and respiratory clinical status were measured by recording the daily mean and maximum Paediatric Early Warning Scores (PEWS). RESULTS: Clonidine was administered via enteral, intravenous, and transdermal routes at a median dose of 2.5 mcg/kg/h (range 0.1-9 mcg/kg/h). Administration of high dose clonidine was associated with decreased use of benzodiazepines, morphine, and propofol: avoiding invasive respiratory support for ¾ cases during admission. Clonidine doses via all routes of administration did not correlate with poorer PEWS scores (p = 0.839). Both high dose intravenous and transdermal clonidine where found to be effective. CONCLUSIONS: High dose clonidine administered via different routes can be used in the acute management of severe exacerbations of dystonia. Its use in our cohort was not associated with significant cardio-respiratory depression even at doses as high as 9 mcg/kg/h.

Inpatient healthcare utilisation in patients with alcoholic liver disease: what are the costs and outcomes?

BACKGROUND: Alcoholic liver disease (ALD) carries a significant cost burden and often leads to inpatient care. It is unclear whether inpatient care for ALD is any more costly than admission for other reasons. AIMS: To compare the costs and outcomes of inpatient care for ALD to two groups: a control group of matched cases admitted in the same time frame and people admitted for other chronic liver diseases (CLD). METHODS: All admissions for ALD and other CLD in a 3-month period were retrospectively identified. Five randomly identified gender- and age-matched contemporaneously admitted controls were allocated. Length of stay (LoS), mortality, inpatient costs, blood product utilisation and discharge destination were compared. RESULTS: Of the 71 admissions due to CLD, ALD was the most frequent cause (53/71, 75%). ALD admissions cost more (median $10 100 vs $5294; P = 0.0012) and had greater LoS (median LoS 7.2 days (interquartile range (IQR) 0.2-40.7)) than controls (2.6 days (IQR 1.1-6.8); P = 0.0001). A larger proportion of the ALD cohort required blood transfusion and had a higher mortality than controls (24.5 vs 6.4%, P = 0.002 and 13.2 vs 0.2%; P < 0.0001 respectively). Self-discharge was more common in the ALD group (13.2 vs 1.1%, P < 0.0001). CONCLUSIONS: ALD inpatient hospital admissions have greater median total cost, longer LoS, greater blood product utilisation, higher mortality and greater rate of discharge against medical advice than age- and gender-matched controls. These data emphasise the large inpatient care burden, high mortality and suboptimal engagement in those with ALD, which justifies the more active provision of services for ALD.

Preconception paternal stress in rats alters dendritic morphology and connectivity in the brain of developing male and female offspring.

The goal of this research was to examine the effect of preconception paternal stress (PPS) on the subsequent neurodevelopment and behavior of male and female offspring. Prenatal (gestational) stress has been shown to alter brain morphology in the developing brain, and is presumed to be a factor in the development of some adult psychopathologies. Our hypothesis was that paternal stress in the preconception period could impact brain development in the offspring, leading to behavioral abnormalities later in life. The purpose of this study was to examine the effect of preconception paternal stress on developing male and female offspring brain morphology in five brain areas; medial prefrontal cortex (mPFC), orbitofrontal cortex (OFC), parietal cortex (Par1), hippocampus (CA1) and nucleus accumbens (NAc). Alterations in dendritic measures and spine density were observed in each brain area examined in paternal stress offspring. Our two main findings reveal; (1) PPS alters brain morphology and organization and these effects are different than the effects of stress observed at other ages; and, (2) the observed dendritic changes were sexually dimorphic. This study provides direct evidence that PPS modifies brain architecture in developing offspring, including dendritic length, cell complexity, and spine density. Alterations observed may contribute to the later development of psychopathologies and maladaptive behaviors in the offspring.

Clinical triage for colonoscopy is useful in young women.

BACKGROUND: Colonoscopy is an invasive procedure and a limited resource. It is therefore desirable to restrict its use to those in whom it yields an important diagnosis, without missing pathology in others. AIM: The aim of this study was to determine whether standard clinical criteria can be used to reliably distinguish when colonoscopy is advisable in women 30 years and younger. METHODS: A retrospective audit was performed at a single centre of 100 consecutive colonoscopies performed in women 30 years old and younger. The indications for the colonoscopy were recorded, and divided into clear and relative indications. The primary outcome of whether an endoscopic diagnosis was made was compared between the two groups. Clear indications for colonoscopy included overt rectal bleeding, elevated inflammatory markers, anaemia, iron deficiency and strong family history of colorectal cancer. Relative indications included abdominal pain or discomfort, bloating and altered bowel habit/motions. RESULTS: The average age was 23 years. Sixty women had both relative and clear indications. Eleven had only clear indications and 28 only relative indications. Altogether, 58 colonoscopies were normal, and 17 showed inflammatory bowel disease. No subject with only relative indications had an abnormal finding (0/28). The diagnostic yield was significantly different between those with only relative indications (0%) versus those with at least one clear indication (59%; P < 0.0001). CONCLUSIONS: Standard clinical criteria can be used to restrict safely the use of colonoscopy in young women. This will avoid performing procedures in people without clear indications, saving costs, resources and complications.

Local and global aspects of biological motion perception in children born at very low birth weight.

Biological motion perception can be assessed using a variety of tasks. In the present study, 8- to 11-year-old children born prematurely at very low birth weight (<1500 g) and matched, full-term controls completed tasks that required the extraction of local motion cues, the ability to perceptually group these cues to extract information about body structure, and the ability to carry out higher order processes required for action recognition and person identification. Preterm children exhibited difficulties in all 4 aspects of biological motion perception. However, intercorrelations between test scores were weak in both full-term and preterm children--a finding that supports the view that these processes are relatively independent. Preterm children also displayed more autistic-like traits than full-term peers. In preterm (but not full-term) children, these traits were negatively correlated with performance in the task requiring structure-from-motion processing, r(30) = -.36, p < .05), but positively correlated with the ability to extract identity, r(30) = .45, p < .05). These findings extend previous reports of vulnerability in systems involved in processing dynamic cues in preterm children and suggest that a core deficit in social perception/cognition may contribute to the development of the social and behavioral difficulties even in members of this population who are functioning within the normal range intellectually. The results could inform the development of screening, diagnostic, and intervention tools.

The influence of cooling conditions on grain size, secondary phase precipitates and mechanical properties of biomedical alloy specimens produced by investment casting.

The objective of this work was to investigate and evaluate the effect of the cooling environment on the microstructure, secondary phase precipitates and mechanical properties of an as-cast cobalt alloy. The microstructure of castings has a large bearing on the mechanical properties, grain size, porosity and the morphology of carbide precipitates are thought to influence hardness, tensile strength and ductility. It is postulated that a greater understanding of microstructure and secondary phase precipitate response to casting parameters could lead to the optimisation of casting parameters and serve to reduce the requirement of thermo-mechanical treatments currently applied to refine as-cast structures and achieve adequate mechanical properties. Thermal analysis was performed to determine the critical stages of cooling. Ten millimetre diameter cylindrical specimens which could be machined into tension test specimens were cast and cooled under different conditions to impose different cooling rates. Analytical techniques such as optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), tensile testing and micro-hardness testing were used to study the specimens. Parameters studied include grain size, secondary dendrite arm spacing, secondary phase precipitates, porosity, hardness, ultimate tensile strength, yield strength and elongation. The microstructure of as-cast Co-28Cr-6Mo was found to consist of a dendritic matrix with secondary phases precipitated at grain boundaries and interdendritic zones. These secondary phase precipitates consist of carbides, rich in chromium and molybdenum. The size and area fraction of carbides was found to decrease significantly with increasing cooling rate while the micro-porosity was only marginally affected. The as-cast grains are illustrated for the first time showing a significant difference in size between insulated and naturally cooled specimens. The secondary dendrite arm spacing was determined to be significantly affected by the various cooling environments and the mechanical properties of hardness, ultimate tensile strength and yield strength all increased with increasing cooling rate while the ductility decreased. Correlations between microstructural features and mechanical properties are proposed.

Wire ablation dynamics model and its application to imploding wire arrays of different geometries.

The paper presents an extended description of the amplified wire ablation dynamics model (WADM), which accounts in a single simulation for the processes of wire ablation and implosion of a wire array load of arbitrary geometry and wire material composition. To investigate the role of wire ablation effects, the implosions of cylindrical and planar wire array loads at the university based generators Cobra (Cornell University) and Zebra (University of Nevada, Reno) have been analyzed. The analysis of the experimental data shows that the wire mass ablation rate can be described as a function of the current through the wire and some coefficient defined by the wire material properties. The aluminum wires were found to ablate with the highest rate, while the copper ablation is the slowest one. The lower wire ablation rate results in a higher inward velocity of the ablated plasma, a higher rate of the energy coupling with the ablated plasma, and a more significant delay of implosion for a heavy load due to the ablation effects, which manifest the most in a cylindrical array configuration and almost vanish in a single-planar array configuration. The WADM is an efficient tool suited for wire array load design and optimization in wide parameter ranges, including the loads with specific properties needed for the inertial confinement fusion research and laboratory astrophysics experiments. The data output from the WADM simulation can be used to simplify the radiation magnetohydrodynamics modeling of the wire array plasma.

Risk of epithelial ovarian cancer in asymptomatic women with ultrasound-detected ovarian masses: a prospective cohort study within the UK collaborative trial of ovarian cancer screening (UKCTOCS).

OBJECTIVE: To estimate the risk of primary epithelial ovarian cancer (EOC) and slow growing borderline or Type I and aggressive Type II EOC in postmenopausal women with adnexal abnormalities on ultrasound. METHODS: This was a prospective cohort study in the ultrasound group of the UK Collaborative Trial of Ovarian Cancer Screening of postmenopausal women with ultrasound-detected abnormal adnexal (unilocular, multilocular, unilocular solid and multilocular solid, solid) morphology on their first scan. Women were followed up through the national cancer registries and by postal questionnaires. Absolute risks of EOC and borderline, Type I and Type II EOC within 3 years of initial scan were calculated. RESULTS: Of 48 053 women who underwent ultrasound examination and had complete scan data, 4367 (9.1% (95% CI, 8.8-9.3%)) had abnormal adnexal morphology. Median follow-up was 7.09 (25(th) -75(th) centiles, 6.03-7.92) years. Forty-seven (32 borderline or Type I, 15 Type II) were diagnosed with EOC. The overall absolute risk of EOC associated with abnormal adnexal morphology was 1.08% (95% CI, 0.79-1.43%); for borderline and Type I it was 0.73% (95% CI, 0.5-1.03%); and for Type II it was 0.34% (95% CI, 0.33-0.79%). In the subgroup (n = 741) with solid elements (unilocular solid, multilocular solid and solid) overall absolute risk was 4.45% (95% CI, 3.08-6.20%), for borderline and Type I it was 3.1% (95% CI, 1.9-4.6%) and for Type II it was 1.3% (95% CI, 0.6-2.4%). 11 982 women had both ovaries visualized and normal annual scans throughout the 3-year follow-up period. In this group, no borderline or Type I and eight Type II cancers were diagnosed. CONCLUSION: Asymptomatic postmenopausal women with ultrasound-detected adnexal abnormalities with solid elements have a 1 in 22 risk for EOC. Despite the higher prevalence of Type II EOC, the risk of borderline or Type I cancer in women with ultrasound abnormalities seems to be higher than does the risk of Type II cancer. This has important immediate implications for patients with incidental adnexal findings as well as for any future ultrasound-based screening.

Endothelial progenitor cells enter the aging arena.

Age is a significant risk factor for the development of vascular diseases, such as atherosclerosis. Although pharmacological treatments, including statins and anti-hypertensive drugs, have improved the prognosis for patients with cardiovascular disease, it remains a leading cause of mortality in those aged 65 years and over. Furthermore, given the increased life expectancy of the population in developed countries, there is a clear need for alternative treatment strategies. Consequently, the relationship between aging and progenitor cell-mediated repair is of great interest. Endothelial progenitor cells (EPCs) play an integral role in the cellular repair mechanisms for endothelial regeneration and maintenance. However, EPCs are subject to age-associated changes that diminish their number in circulation and function, thereby enhancing vascular disease risk. A great deal of research is aimed at developing strategies to harness the regenerative capacity of these cells. In this review, we discuss the current understanding of the cells termed "EPCs," examine the impact of age on EPC-mediated repair and identify therapeutic targets with potential for attenuating the age-related decline in vascular health via beneficial actions on EPCs.
