Abstract STUDY QUESTION How does the risk of cardiovascular disease (CVD) vary with type and age of menopause? SUMMARY ANSWER Earlier surgical menopause (e.g. <45 years) poses additional increased risk of incident CVD events, compared to women with natural menopause at the same age, and HRT use reduced the risk of CVD in women with early surgical menopause. WHAT IS KNOWN ALREADY Earlier age at menopause has been linked to an increased risk of CVD mortality and all-cause mortality, but the extent that this risk of CVD varies by type of menopause and the role of postmenopausal HRT use in reducing this risk is unclear. STUDY DESIGN, SIZE, DURATION Pooled individual-level data of 203 767 postmenopausal women from 10 observational studies that contribute to the International collaboration for a Life course Approach to reproductive health and Chronic disease Events (InterLACE) consortium were included in the analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Postmenopausal women who had reported menopause (type and age of menopause) and information on non-fatal CVD events were included. Type of menopause (natural menopause and surgical menopause) and age at menopause (categorised as <35, 35–39, 40–44, 45–49, 50–54 and ≥55 years) were exposures of interest. Natural menopause was defined as absence of menstruation over a period of 12 months (no hysterectomy and/or oophorectomy) and surgical menopause as removal of both ovaries. The study outcome was the first non-fatal CVD (defined as either incident coronary heart disease (CHD) or stroke) event ascertained from hospital medical records or self-reported. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% CI for non-fatal CVD events associated with natural menopause and surgical menopause. MAIN RESULTS AND THE ROLE OF CHANCE Compared with natural menopause, surgical menopause was associated with over 20% higher risk of CVD (HR 1.22, 95% CI 1.16–1.28). After the stratified analysis by age at menopause, a graded relationship for incident CVD was observed with lower age at menopause in both types of natural and surgical menopause. There was also a significant interaction between type of menopause and age at menopause (P < 0.001). Compared with natural menopause at 50–54 years, women with surgical menopause before 35 (2.55, 2.22–2.94) and 35–39 years (1.91, 1.71–2.14) had higher risk of CVD than those with natural menopause (1.59, 1.23–2.05 and 1.51, 1.33–1.72, respectively). Women who experienced surgical menopause at earlier age (<50 years) and took HRT had lower risk of incident CHD than those who were not users of HRT. LIMITATIONS, REASONS FOR CAUTION Self-reported data on type and age of menopause, no information on indication for the surgery (e.g. endometriosis and fibroids) and the exclusion of fatal CVD events may bias our results. WIDER IMPLICATIONS OF THE FINDINGS In clinical practice, women who experienced natural menopause or had surgical menopause at an earlier age need close monitoring and engagement for preventive health measures and early diagnosis of CVD. Our findings also suggested that timing of menopause should be considered as an important factor in risk assessment of CVD for women. The findings on CVD lend some support to the position that elective bilateral oophorectomy (surgical menopause) at hysterectomy for benign diseases should be discouraged based on an increased risk of CVD.

Introduction: Evidence from clinical trials and observational studies on the relationship between menopausal hormone therapy (MHT) and cardiovascular disease (CVD) risk has been discordant. Hypothesis: We hypothesized that the association between MHT and risk of CVD might be affected by both age at menopause and age when initiated MHT. Methods: We harmonised and pooled individual-level data from 15 studies across five countries/regions (Australia, Scandinavia, USA, Japan, and UK). Postmenopausal women who had reported their MHT status (user or non-user) and CVD status (occurred or not, including coronary heart disease (CHD) and stroke) were included. We used Cox proportional hazards models to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for the association between MHT use and incident CVD. We stratified the analyses by age when initiated MHT and age at natural menopause to examine the interaction between MHT, age initiated MHT, and age at menopause on incident CVD. Results: Overall, 190 625 postmenopausal women were included. We identified 10 601 incident CVD events, including 7615 CHD and 3543 strokes. Around 39% (74 585) women were MHT users. Compared to non-users of MHT, women who were MHT users had 10% higher risk of incident CVD (HR 1.10, 95% CI 1.06-1.14), with HR (95% CI) of (1.15, 1.10-1.20) for CHD and (1.02, 0.96-1.09) for stroke. After stratifying by age at natural menopause, women who experienced menopause after age 45 years and took MHT had around 15% higher risk of CHD, while the significant association with incident stroke was only observed in women who had menopause after 55 years (1.16, 1.01-1.33). After a further stratification by age initiated MHT, we found the significant associations between MHT users and incident CVD were only observed in women who experienced menopause after age 45 years and took MHT at age 60 years or old (Table 1). Conclusions: Postmenopausal women who experienced natural menopause after age 45 years and took MHT after age 60 years had increased risk of incident CVD.

The purpose of this review is to summarize the role of fetuin-A in disease processes prevalent in postmenopausal women and synthesize effective interventions in obtaining healthy fetuin-A levels. A review of databases for articles related to fetuin-A and diseases associated with postmenopausal women was conducted. Articles were limited to full-text access, published in English since 1944. High fetuin-A levels are closely associated with decreased bone mineral density, increased cardiovascular disease risks, impairment of insulin signaling and disruption of adipocyte functioning. Postmenopausal women have increased risk of osteoporosis, cardiovascular disease, insulin-resistance, intra-abdominal fat accumulation and vascular calcification. Low-levels of fetuin-A have been shown to be protective against the latter. The role of fetuin-A is multi-factorial and the mechanisms in which it is involved in each of these processes are vast. The present body of literature is inconsistent in defining high versus low levels of fetuin-A and their association with healthy-matched controls. The diseases associated with high levels of fetuin-A mimic diseases most prevalent in postmenopausal women. In addition, there is no research, to date, exploring fetuin-A levels in postmenopausal women and the associations it may or may not have in related diseases.Key words: fetuin-A; Alpha2-Heremans-Schmid glycoprotein; cardiovascular disease; and elderly, insulin-resistance, intra-abdominal fat, metabolic syndrome, exercise, weight-loss, calorie restriction and postmenopausal.Resumen. El propósito de esta revisión es sintetizar el papel de la fetuina A en los procesos de enfermedad prevalentes en mujeres posmenopáusicas y resumir las intervenciones efectivas que permiten obtener niveles saludables de fetuina A. Para ello, se revisaron bases de datos con artículos relacionados con fetuina A y las enfermedades asociadas con mujeres posmenopáusicas. La búsqueda de artículos se limitó a aquellos de texto completo publicados en el idioma inglés desde el año 1944. Se encontró que altos niveles de fetuina A están íntimamente relacionados con una reducción de la densidad mineral ósea, un aumento en el riesgo de enfermedad cardiovascular, deterioro de la señalización de la insulina y la alteración del funcionamiento de los adipocitos. Las mujeres posmenopáusicas tienen un mayor riesgo de osteoporosis, enfermedad cardiovascular, resistencia a la insulina, acumulación de grasa intra abdominal y calcificación vascular. Se ha demostrado que niveles bajos de fetuina A son protectores contra esta última condición. El papel de fetuina A es multifactorial y los mecanismos en los que está involucrado en cada uno de estos procesos son muy amplios. El estado actual de la literatura no es consistente en la definición de niveles de fetuina A altos versus bajos y su asociación con controles sanos. Las enfermedades asociadas con altos niveles de fetuina A asemejan las enfermedades más prevalentes en mujeres posmenopáusicas. Además, no existen investigaciones, hasta la fecha, en las que se   exploren los niveles de fetuina A en mujeres posmenopáusicas y las asociaciones que puede o no puede tener en las enfermedades relacionadas.Palabras claves: fetuina A, glicoproteína Alpha2-Heremans-Schmid, enfermedad cardiovascular, adulto mayor, resistencia a la insulina, grasa intra abdominal, síndrome metabólico, ejercicio, pérdida de peso, restricción calórica, posmenopausia.

Purpose: To describe global quality of life (GLQL) in patients with metastatic testicular cancer (TC) treated with four different schedules of bleomycin, etoposide, and cisplatin (BEP) chemotherapy (four v three cycles given over 5 v 3 days). Patients and Methods: Quality-of-life data were prospectively collected in 666 patients with metastatic TC entered into the European Organization for Research and Treatment of Cancer (EORTC) Trial 30941/United Kingdom Medical Research Council Trial TE20, using the EORTC Quality-of-Life Questionnaire C30 and a TC module. Data were analyzed by a mixed effects model and by evaluation of clinically relevant changes at 2 years. Results: The pattern of GLQL changes was similar in the four groups. Two years after chemotherapy, 36% of patients displayed improved GLQL as compared with baseline, whereas GLQL had deteriorated in 13%. At 3 months, patients receiving the 3-day regimen experienced increased gastrointestinal (GI) toxicity more than those receiving the 5-day regimen, with the difference reaching the level of clinical relevance (≥ 10-point change) if four cycles were given. The 3-day schedule increased the 2-year risk of tinnitus, with clinical relevance demonstrated after four cycles. Long-term peripheral neuropathy and Raynaud-like phenomena were not associated with the number of cycles or days per cycle. At 2 years, Raynaud-like phenomena, tinnitus, or reduced hearing were reported by 21% to 26% of the patients. Conclusion: Because of the excess of acute GI toxicity and the increased risk of tinnitus after the 3-day regimen, we recommend the 5-day regimen if four cycles of BEP are planned. If only three cycles are to be given, then the 3-day regimen is acceptable, even given the increased risk of nausea/vomiting at 3 months.

AbstractPostmenopausal women have an increased risk for cardiovascular diseases. It has been postulated that the loss of ovarian function and subsequent deficiency of endogenous estrogens after menopause contributes to this elevated risk of cardiovascular disease in postmenopausal women. Compared with woman entering menopause at the mean age of 51 years, in women with early menopause or premature ovarian insufficiency the risk for cardiovascular disease is even greater. These women lack the cardioprotective effect of endogenous estrogens for many more years than do women entering natural menopause. The majority of data assessing the risk of cardiovascular disease in relation to age at menopause and specifically premature menopause are derived from large epidemiological cohort studies. In addition, observations in women undergoing bilateral oophorectomy at an early age provide convincing evidence regarding association between early menopause or POI and the development of cardiovascular events and mortality. Moreover, genetic variants associated with earlier age at menopause have also been found to increase the risk of cardiovascular events in women. It has been substantiated that hormone replacement therapy (HRT) decreases the risk for ischemic heart disease and eliminates the increased cardiovascular disease mortality. It is therefore crucial to start HRT as soon as possible, particularly in women with premature ovarian insufficiency.

Abstract Background Our goal was to describe the characteristics and posttreatment outcomes of pediatric patients with central nervous system (CNS) tuberculosis (TB) and to identify factors associated with poor outcome. Methods We included children aged 0 to 18 years with CNS TB reported to the California TB registry between 1993 and 2011. Demographics, clinical characteristics, severity of disease at presentation (Modified Medical Research Council stage I, II, or III [III is most severe]), treatment, and outcomes during the year after treatment completion were abstracted systematically from the medical and public health records. Patient outcomes were categorized as good or poor on the basis of disability in hearing, vision, language, ambulation, and development and other neurologic deficits. Results Among 151 pediatric CNS TB cases reported between 1993 and 2011 in California for which records were available, 92 (61%) cases included sufficient information to determine outcome. Overall, 55 (60%) children had a poor outcome. After we adjusted for age (0 to 4 years), children with stage III severity (vs I or II; prevalence rate ratio [PRR], 1.4 [95% confidence interval (CI), 1.1–1.9]), a protein concentration of >100 mg/dL on initial lumbar puncture (PRR, 1.2 [95% CI, 1.03–1.4]), or infarct on neuroimaging (PRR, 1.2 [95% CI, 1.04–1.3]) were at increased risk for a poor outcome. In multivariate analysis, an age of 0 to 4 years (vs >4 years; PRR, 1.4 [95% CI, 1.2–1.7]) and a stage II or III Modified Medical Research Council score (vs stage I; PRR, 1.2 [95% CI, 1.03–1.5]) remained significantly associated with poor outcome. Conclusions Pediatric patients with CNS TB in California are left with high rates of disabling clinical sequelae after treatment. The identification of modifiable factors is critical for improving outcomes.
