Efficacy and safety of ultra-low-dose estradiol and norethisterone in postmenopausal Brazilian women.

OBJECTIVE: This study aimed to evaluate the efficacy and safety of oral ultra-low-dose continuous combination of 17ß-estradiol (17ß-E2) and norethisterone acetate (NETA) in postmenopausal Brazilian women. METHODS: Postmenopausal women (age 45-60 years) with amenorrhea >12 months and intact uterus, with moderate to severe vasomotor symptoms, were included. The vasomotor symptoms and endometrial bleeding were evaluated by a daily diary for 24 weeks, and the women were assessed at baseline and endpoint. RESULTS: A total of 118 women were included. The group treated with 0.5 mg 17ß-E2/0.1 mg NETA (n = 58) showed a percentage reduction of 77.1% in the frequency of vasomotor symptoms versus 49.9% in the placebo group (n = 60) (p = 0.0001). The severity score showed a reduction in the treatment group when compared to the placebo (p < 0.0001). The adverse events were comparable between the groups; however, in the 0.5 mg 17ß-E2/0.1 mg NETA group there were more complaints of vaginal bleeding; despite that, in most cycles in both treatment groups, more than 80% of women experienced amenorrhea. CONCLUSIONS: The combination of 0.5 mg 17ß-E2/0.1 mg NETA in a continuous combination regimen was shown to be effective in reducing the frequency and severity of vasomotor symptoms in Brazilian postmenopausal women.

Profile of Brazilian climacteric women: results from the Brazilian Menopause Study.

OBJECTIVE: This study aims to understand the epidemiological characteristics of Brazilian menopausal women, and their view on menopause hormone therapy (MHT). METHODS: A national cross-sectional study with 1500 women between 45 and 65 years old was carried out through questionnaires. RESULTS: The overall median age of participants was 52 [47-56] years, and 55 [52-59] years for the postmenopausal subgroup. Menstrual irregularity started at median age 46 [44-49] years. Median menopause age was 48 [45-51] years with no differences between socioeconomic classes. The prevalence of any climacteric symptoms was 87.9% and hot flashes started at median age 47 [45-50] years. Among women in menopause/menopausal transition, 52.1% received any medical prescription, and MHT was recommended for 22.3%. Among those who started MHT, 45.4% were still using the treatment and the median duration of use was 8 months, but different among socioeconomic classes (24 months for class A against 3 months for class D/E). CONCLUSIONS: In this first Brazilian national population-based study on menopause and MHT, it was observed that, in spite of being symptomatic when entering menopause around 48 years of age, only a small part of Brazilian women started MHT and the median duration of treatment was less than 1 year, but the duration was higher for higher socioeconomic class.

Impact of postmenopausal vaginal discomfort on sex and relationships in Brazil: the CLOSER survey.

OBJECTIVE: The CLOSER (CLarifying Vaginal Atrophy's Impact On SEx and Relationships) survey investigated how postmenopausal vaginal atrophy (VA) affects relationships between Brazilian women and male partners. METHODS: Postmenopausal women (age 55-65 years) with VA, and male partners of women with the condition, completed an online survey on the impact of VA and local estrogen treatment on intimacy and relationships. RESULTS: A total of 360 women and 352 men from Brazil were included. Women (83%) and men (91%) reported that they were comfortable discussing VA with their partners. Women's key source of information on VA was health-care providers (HCPs), but 44% felt that not enough information is available. VA caused 70% of women to avoid sexual intimacy and resulted in less satisfying sex. VA had a negative impact on women's feelings and self-esteem. Women (76%) and men (70%) both reported that treatment with vaginal estrogen improved their sexual relationship, primarily by alleviating women's pain during sex. Women (56%) and men (59%) felt closer to each other after treatment. CONCLUSIONS: VA had a negative impact on sexual relationships for both women and men in Brazil, and reduced women's self-confidence. Vaginal hormone therapy improved couples' sexual relationships. A proactive attitude of HCPs is essential to educate women on VA and the potential benefits of treatment.

Vaginal Health: Insights, Views & Attitudes survey in Latin America (VIVA-LATAM): focus on Brazil.

OBJECTIVE: A previous survey investigated postmenopausal vaginal atrophy in a sample of women across Latin America. To help implement a tailored approach to improve postmenopausal care and outcomes in Brazil, we consider results from the survey for this country. METHODS: A total of 2509 postmenopausal women resident in Argentina, Brazil, Chile, Colombia, or Mexico completed an online questionnaire. The Brazilian cohort comprised 504 women. RESULTS: Over half of the Brazilian cohort (56%) reported experiencing symptoms of vaginal atrophy; most described them as moderate or severe (76%), and almost half (48%) experienced symptoms for at least 1 year. Three-quarters of the Brazilian cohort (75%) were unaware of the chronic nature of the condition. Upon experiencing symptoms of vaginal atrophy, 92% had visited a health-care provider to discuss treatment options. Overall, 56% were aware of some form of local hormone therapy and 40% of those affected by vaginal atrophy had used such treatment. CONCLUSION: Postmenopausal women in Brazil are likely to benefit from increased awareness of the symptoms of vaginal atrophy. Health-care providers can potentially improve outcomes by helping women to understand the chronic nature of the condition and available treatment options. Women may be open to education pre menopause, before symptoms occur.

Solitary dilated duct visualised by mammography: ultrasound and anatomopathological correlation.

AIM: To correlate solitary dilated ducts (SDDs) detected by mammography with ultrasound and histopathological findings of intraductal lesions and evaluate the association with invasive or in situ breast carcinoma. The secondary goal was to evaluate the prevalence of SDDs in screening and diagnostic mammography. MATERIALS AND METHODS: This prospective study of consecutive screening and diagnostic mammograms from March 2016 to March 2017 at a referral centre for the diagnosis and treatment of breast cancer was registered at clinicatrials.gov (NCT03161392). SDDs were recorded prospectively on mammography, and regardless of the findings' stability, the participants were recalled for targeted ultrasound to evaluate the intraductal content, which was submitted to histopathological analysis when heterogeneous content or masses were found. SDD stability was evaluated for 2 years. The categorical data are shown as frequency and percentage, and the comparisons were conducted using the chi-squared test. RESULTS: A total of 9,035 mammograms were evaluated. SDDs were identified in 130 (1.43%) mammograms and 94 targeted ultrasound were conducted. In 22 cases, histological analysis were performed, and the main findings were fibrocystic changes (n = 14) and papilloma (n = 8). The main clinical and imaging characteristics associated with statistical significance (p < 0.05) were the presence of nipple discharge, intraductal masses, and calcifications on mammography. CONCLUSION: SDDs visualised using mammography and without other associated findings should be complemented with targeted ultrasound to evaluate the intraductal content that shows benign histopathological results when papilloma is the most relevant finding. No cases of invasive or in situ breast carcinoma were found in this study.

Effects of estradiol, progestogens, and of tibolone on breast proliferation and apoptosis.

AIM: To study the effects of estrogen therapy, alone or combined with progestogens, and of tibolone on the expression of proliferation and apoptosis markers in normal breast tissue. METHODS: Thirty 250-day-old Wistar rats were castrated and 3 weeks later received one of the following treatments by gavage for 5 weeks: (1) estradiol benzoate; (2) estradiol benzoate + medroxyprogesterone acetate; (3) estradiol benzoate + norethisterone acetate; (4) estradiol benzoate + dydrogesterone; (5) tibolone; (6) placebo. Following treatment, the expression of proliferating cell nuclear antigen (PCNA) and caspase-3 was analyzed by quantitative immunohistochemistry in the breast tissue, and proliferation and apoptosis were analyzed semiquantitatively by microscopic imaging. RESULTS: There was a statistically significant difference among the groups for PCNA, caspase-3 and the caspase-3 : PCNA ratio. Tibolone was associated with the lowest proliferative activity, followed by estradiol benzoate + dydrogesterone; however, estradiol benzoate + dydrogesterone showed the greatest rate of apoptosis. CONCLUSIONS: The various progestogens can have more or less proliferative and pro-apoptotic effects than estradiol alone. Among the treatment schemes analyzed, the estradiol + dydrogesterone combination resulted in a higher apoptosis rate in relation to the proliferation rate and tibolone was associated with the lowest proliferation.

Is expression of rat breast matrix components influenced by estrogen, progestins and tibolone?

AIM: To study the effects of estrogen therapy, alone or combined with progestogens, and of tibolone on the expression of heparanase (HSPE), extracellular matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9), perlecan and proliferating cell nuclear antigen (PCNA) in normal breast tissue. METHODS: Thirty 250-day-old Wistar rats were castrated and 3 weeks later received one of the following treatments by gavage for 5 weeks: (1) estradiol benzoate; (2) estradiol benzoate + medroxyprogesterone acetate; (3) estradiol benzoate + norethisterone acetate; (4) estradiol benzoate + dydrogesterone; (5) tibolone; (6) placebo. Following treatment, the expressions of mRNA for HSPE, MMP-2 and MMP-9 were analyzed by real-time PCR and the protein expressions of HSPE, MMP-2, MMP-9, perlecan and PCNA were quantified by immunohistochemistry. RESULTS: There was a statistically significant difference among the groups for the expression of HSPE mRNA due to high levels in the tibolone group. The groups differed in terms of PCNA, with lower levels found in the tibolone group followed by the estradiol benzoate + dydrogesterone group. A statistically significant positive correlation was observed for PCNA versus perlecan and MMP-9. CONCLUSIONS: There was no difference in the effects of combinations of estradiol and different progestogens on extracellular matrix components, and breast cell proliferation was associated with increases in perlecan and MMP-9.

Association of breast vascular calcifications with low bone mass in postmenopausal women.

BACKGROUND: In developing countries, there is a deficiency of densitometers with which to screen the population for osteoporosis. Thus, strategies with which to select patients for a bone density test are desirable. OBJECTIVE: To determine whether breast vascular calcifications (BVCs) may be employed to identify postmenopausal women with osteoporosis/osteopenia. METHODS: This was a cross-sectional study of postmenopausal women subjected to bilateral mammography and bone densitometry (DXA) of the spine and hip. A medical interview registered possible confounding factors, such as age, length of menopause, previous use of postmenopausal hormone therapy, family history of osteoporosis, smoking, alcoholism, hypertension, diabetes, cardiovascular diseases, and medication use. RESULTS: The study included 211 postmenopausal women aged 62.1 ± 9.3 years, 38 of whom (18.0%) exhibited BVC. Osteoporosis was detected in 36 (17.1%), and a T-score < 21.0 for any site was found in 164 (77.7%). No statistically significant difference was found between the groups without BVC (n = 173) and with BVC (n = 38) for the prevalence of 'osteoporosis' or 'moderate/severe osteopenia or osteoporosis' at the spine or at any other site. There was a difference between the groups in terms of age (59.0 ± 7.8 vs. 71.9 ± 8.9 years, respectively; p < 0.001), sedentary lifestyle (57.8% vs. 84.2%, respectively; p = 0.002), smoking (27.7% vs. 7.9%, respectively; p = 0.009), and high blood pressure (65.3% vs. 92.1%, respectively; p = 0.001). Logistic regression analysis confirmed the lack of statistical significance for BVC as a predictor of an osteoporosis diagnosis. Sensitivity values of BVCs to detect osteoporosis or osteopenia ranged from 17.9% to 25.0%. CONCLUSION: BVCs have been shown to be inadequate to identify postmenopausal women with osteoporosis or osteopenia.

Reversal of rocuronium induced neuromuscular block with sugammadex or neostigmine: a large observational study.

BACKGROUND: This 'real-life' study aimed to analyze the time from the start of neostigmine or sugammadex administration to recovery to a train of four ratio (TOFr) of 0.9 in a real-life in patients receiving rocuronium. The secondary aims were to assess the proportion of patients: presenting TOFr < 0.9 after 5, 10, and 20 min from reversal agent administration, receiving opioids for intraoperative analgesia and extubated in the post-anesthesia care unit (PACU). METHODS: This was a multisite, prospective, nonrandomized, observational real-life study. Reversal agent was administered at either T2 reappearance or at a post-tetanic count of 1 or 2. Drugs dosages were free according to each investigator's usual practice. RESULTS: Three hundred fifty-nine patients were enrolled onto the study. Time from reversal administration to TOFr to 0.9 is significantly faster in the sugammadex group than in the neostigmine group (shallow block: 2.2 vs. 6.9 min, respectively; P < 0.0001; deep block: 2.7 vs. 16.2 min, respectively; P < 0.0001). The number of patients with TOFr < 0.9 at 5, 10, and 20 min post-reversal agent administration was higher in the neostigmine than in the sugammadex group. Just five patients did not receive opioids. All patients were extubated in the operative room except for a single patient in the sugammadex group who was extubated following PACU admission. CONCLUSIONS: This real-life study confirms that reversal time is faster in patients receiving sugammadex than in those receiving neostigmine. TOFr < 0.9 20 min after reversal was only present in patients treated with neostigmine.

Morphological variability of black bullhead Ameiurus melas in four non-native European populations.

External morphology in black bullhead Ameiurus melas, a fish species considered to have high invasive potential, was studied in its four non-native European populations (British, French, Italian and Slovak). The aim of this study was to examine this species' variability in external morphology, including ontogenetic context, and to evaluate its invasive potential. Specimens from all non-native populations reached smaller body size compared to individuals from native populations. Juvenile A. melas were found to have a relatively uniform body shape regardless of the population's origin, whereas adults developed different phenotypes depending upon location. Specimens from the U.K., Slovak and French populations appeared to be rather similar to each other, whereas the Italian population showed the most distant phenotype. This probably results from the different thermal regime in the Italian habitat. Ameiurus melas from non-native European populations examined in this study showed some potential to alter the body shape both within and between populations. The phenotypic plasticity of A. melas, however, was not found to be as significant as in other invasive fish species. The results suggest that morphological variability itself is not necessarily essential for invasive success. The invasiveness of A. melas is therefore probably favoured by variations in its life-history traits and reproduction variables, together with some behavioural traits (e.g. voracious feeding and parental care) rather than by phenotypic plasticity expressed in external morphology.

Effect of estrogen therapy on vascular perlecan and metalloproteinases 2 and 9 in castrated rats.

AIM: To study the effects of estrogen therapy on the expression of matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) and perlecan in the vascular wall. METHODS: Twenty 180-day-old Wistar rats were castrated and treated 1 week later for a period of 4 weeks with one of the following: (1) placebo; (2) 0.5 µg/day estradiol benzoate (E(2)B); (3) 5 µg/day E(2)B; (4) 50 µg/day E(2)B. A fifth group consisted of rats that had not been castrated. Following treatment, expression of MMP-2 and MMP-9 mRNA (MMP-2([RNA]) and MMP-9([RNA]), respectively) was analyzed by real-time PCR, and expression of MMP-2 (MMP-2([IH])), MMP-9 (MMP-9([IH])) and perlecan was quantified by immunohistochemistry, in carotid walls. RESULTS: There were no differences among castrated groups for MMP-2([RNA]) (p = 0.1969) and for MMP-9([RNA]) (p = 0.1828); however, a correlation was observed between E(2)B dose and MMP-9([RNA]) levels (r = 0.471, p = 0.018). Differences among groups were observed for MMP-2([IH]), MMP-9([IH]) and perlecan (p < 0.0001), wherein higher levels were observed in animals treated with estrogen therapy, correlating with E(2)B doses in the case of MMP-9 (r = 0.441, p = 0.026) and perlecan (r = 0.574, p = 0.005). CONCLUSIONS: Estrogen therapy correlates with higher levels of MMP-2, MMP-9 and perlecan in the extracellular matrix of carotid walls in castrated rats, in a dose-dependent manner. There was a dose-response effect of E(2)B on the expression of MMP-9 mRNA and, possibly, MMP-2 mRNA.

Empirical standard mass equation for Salmo marmoratus.

Total length (L(T)) (range 24-1000 mm; mean ±S.E. = 170.21 ± 0.36 mm) and mass (W) (range 0.10-9590 g; mean ±S.E. = 76.03 ± 0.87 g) of 36,460 specimens of marble trout Salmo marmoratus were used to compute a standard mass (W(s)) equation for this species by means of the empirical percentile (EmP) method. The EmP W(s) equation calculated was: log(10) W(s) = -5.208 + 3.202 log(10) L(T) - 0.046 (log(10) L(T))(2) (L(T) range 90-570 mm) and it is valid throughout the species' area of distribution across Europe.

Neuromuscular block in Italy: a survey of current management.

BACKGROUND: Little is known about current use of neuromuscular blocking agents by Italian anesthetists. This paper reports the results of a survey conducted to obtain information about current management of neuromuscular block in Italy. METHODS: A questionnaire was given to Italian Anesthetists attending the 64nd National Congress of the Italian Society of Anesthesia, Intensive Care, Analgesia and Intensive Therapy S.I.A.A.R.T.I. (Parma, 13th-16th October 2010). Collected data were stratified by age, geographical location, and the total number of surgical procedures performed in the hospitals concerned. RESULTS: One thousand four hundred forty patients correctly compiled questionnaires were collected. 50% of respondents used clinical tests to monitor the level of neuromuscular blockade. The main clinical tests cited for the evaluation were: keeping the head lifted up for 5 seconds, protruding the tongue and opening the eyes. Train-of-four was used by 50% of respondents on a routine basis. Only 33% of anesthetists reply that a train-of-four ratio of 90% or more is the safe level prior to extubation. CONCLUSION: Clinical signs are used by most of the Italian anesthetists to assess the recovery from neuromuscular blockade. There is poor awareness about their inability to indicate even a significant degree of residual neuromuscular block. A more extensive use of quantitative instrumental monitoring is required for the more rational use of neuromuscular blocking agents.

Perioperative intra- and extravascular volume in liver transplant recipients.

UNLABELLED: Assessing adequate volemia to avoid fluid overload and pulmonary edema perioperatively in liver transplantation (LT) is a challenge both for the anesthetist and the intensivist. Volumetric preload indices, such as intrathoracic blood volume index (ITBVI), measured by transpulmonary thermodilution, and continuous end-diastolic volume index (EDVI), measured by pulmonary artery thermodilution, were shown to better reflect preload than central venous pressure (CVP) or pulmonary artery occlusion pressure (PAOP). An ITBVI increase soon after the graft reperfusion influenced pulmonary perfusion without an alteration of extravascular lung water index (EVLWI) and without impaired oxygenation. This study was designed to evaluate relationships between CVP, PAOP, ITBVI, EDVI, and stroke volume index (SVI) within 48 hours after LT. We also investigated the relationship between EVLWI and arterial partial pressure of oxygen and inspired oxygen fraction ratio (PaO(2)/FiO(2)). METHODS: We enrolled 125 patients (103 men and 22 women) undergoing LT. All patients were monitored with the PiCCO system (Pulsion Medical System) and with advanced pulmonary artery catheter connected to the Vigilance System. Hemodynamic-volumetric data were collected upon intensive care unit admission and every 8 hours up to 48 hours. Univariate and multivariate regression models were fitted to assess associations between SVI and EDVI, ITBVI, and filling pressures after adjusting for the right ventricular ejection fraction (RVEF, categorized as ≤30, 31-40, or >40) and the phase of the observation period. We also assessed associations between PaO(2)/FiO(2) and EVLWI. RESULTS: SVI was associated with EDVI, ITBVI, and RVEF. The models showing the best fit to the data were those including EDVI and ITBVI. Neither CVP nor PAOP showed correlation with SVI. EVLWI inversely correlated with PaO(2)/FiO(2). CONCLUSIONS: In the first 48 hours after LT, ITBVI and EDVI were associated with SVI assessment, whereas CVP and PAOP were not related. EVLWI significantly inversely correlated with PaO(2)/FiO(2).

Goal-directed therapy in anesthesia: any clinical impact or just a fashion?

Goal-directed therapy (GDT) describes the protocolized use of cardiac output and related parameters as end-points for fluid and/or inotropic therapy administration. Identifying the patient who will benefit from it has implications throughout perioperative management. The fundamental principle behind GDT is optimizing tissue perfusion by manipulating heart rate, stroke volume, hemoglobin and arterial oxygen saturation to improve oxygen delivery by using fluids, inotropes, red blood cells and supplementary oxygen. Although cardiac output and SvO2 were previously measured using the pulmonary artery catheter, a number of less invasive methods are now available. For intraoperative GDT, the esophageal Doppler-derived Flow Time correct (FTc) is the parameter used most frequently, although other parameters such as stroke volume obtained from Vigileo, PICCO and/or LiDCO, mixed and/or central venous oxygen saturation (SvO2/ScvO2), oxygen delivery and global end diastolic volume (PiCCO system) may be applied in daily clinical practice. The correct target to be followed during the intraoperative period must be clearly established. Most parameters depend primarily on O2 consumption and are not reliable or useful during anesthesia. To date, the quantity and the type of fluids to administer during major elective surgery remain an object of continuing debate. In conclusion, in terms of evidence-based medicine, GDT during anesthesia has a clinical impact when performed using an FTc-based fluids algorithm protocol. In contrast, GDT can be considered unreliable if confusing targets such as SvO2 or ScvO2 higher than 70% during anesthesia are followed.

Liver transplant quality and safety plan in anesthesia and intensive care medicine.

Patients scheduled for orthotopic liver transplantation (OLT) may have coexisting diseases and more likely receive grafts of poorer quality than in the past. Perioperative mortality and morbidity are usually due to a combination of factors related to the patient, graft, surgery, anesthesia, and intensive care management. Anesthesia and intensive care are the areas with the highest frequency and severity of errors. Error and accident risks are always present in this context where a human component is unavoidable. The matter of medical errors is becoming noteworthy worldwide. Nevertheless, data concerning medical errors during OLT are not available in Italy. There are only hypothetical evaluations. The number of adverse events may be high, but so far no specific programs have been developed to increase patient safety. To improve patient safety, anesthesia and intensive care units must use a proactive approach dedicated to an OLT program. We have presented herein a prevention policy to detect errors before they happen through incident reporting, anonymous and voluntary reports of adverse events or near misses, operating room checklists (patient, drugs, devices, equipment), improved training, safer facilities, equipment function, and adequate drug supplies for an OLT program.

Effect of abrupt discontinuation versus gradual dose reduction of postmenopausal hormone therapy on hot flushes.

OBJECTIVE: To compare the effects of the abrupt discontinuation of postmenopausal hormone therapy (HT) and reduction of the daily dosage of the hormone on climacteric symptoms. METHODS: The study included Brazilian postmenopausal women who were using estrogen-progestogen hormone therapy in full doses previously prescribed for vasomotor symptoms. The patients were randomized to receive one of three treatments: placebo for 6 months; estradiol (E2) 1 mg/day + norethisterone acetate (NETA) 0.5 mg/day for 2 months, followed by placebo for 4 months; or E2 1 mg/day + NETA 0.5 mg/day for 4 months, followed by placebo for 2 months. The climacteric symptoms were assessed by the Blatt-Kupperman Menopausal Index at baseline and at 2, 4 and 6 months. Statistical evaluation was performed using the chi(2) or Fisher's test for categorical data, the Kruskal-Wallis test for numerical data, and ANOVA for time and group relationship with the Blatt-Kupperman Menopausal Index. RESULTS: We randomized 60 women (20 in each group), and 54 completed the study. It was observed that both the full Blatt-Kupperman Menopausal Index and the hot flush score did not change significantly in the HT group during low-dose therapy compared with baseline; however, the evaluation performed at 2 months after low-dose-HT cessation showed that the full Blatt-Kupperman Menopausal Index and the hot flush score were similar to those of the group who stopped HT abruptly and significantly higher than at baseline (hot flush scores: p < 0.001 for all three groups at months 2, 4 and 6, respectively, vs. baseline). CONCLUSION: Discontinuation of HT by reducing the daily dose of estrogen for a period of 2 or 4 months did not differ in its effect from that of abrupt cessation with regard to vasomotor symptoms.

Knowledge of residual curarization: an Italian survey.

BACKGROUND: The use of neuromuscular blocking agents (NMBAs) is widespread in anesthetic practice; little is known about the current use of these drugs in Italy. This survey was conducted to obtain information about the most commonly used clinical tests and the train-of-four (TOF) ratios that are considered as being reliable for assessing recovery from neuromuscular blockade at the end of anesthesia and the estimated occurrence rates of post-operative paralysis in Italian hospitals. METHODS: The questionnaire was given to Italian anesthesiologists attending the 62nd National Congress of the Italian Society of Anesthesia, Analgesia and Intensive Therapy. Collected data were stratified by age and the total number of surgical procedures performed in the hospitals concerned. RESULTS: Seven hundred and fifty-four correctly compiled questionnaires were collected (response rate 88.7%). Seventy three percent of the respondents only used clinical tests for monitoring the level of neuromuscular blockade. The main clinical tests cited for the evaluation of residual paralysis were keeping the head lifted up for 5 s, protruding the tongue and opening the eyes. TOF was used by 35% of the respondents on a routine basis. Only 24% of the interviewed anesthesiologists reported that before extubation, a TOF ratio of at least 0.9 should be reached. CONCLUSIONS: Most Italian anesthetists assess the recovery from neuromuscular blockade only by clinical signs. There is poor awareness about the inability of such techniques to indicate even a significant amount of residual neuromuscular block. A more extensive use of quantitative instrumental monitoring is required for the more rational use of NMBAs.

Breast arterial calcification is a predictive factor of cardiovascular disease in Brazilian postmenopausal women.

OBJECTIVE: The objectives of this study were to evaluate the association between cardiovascular disease (CVD) and breast arterial calcification (BAC), as well as the prevalence rates of these conditions in Brazilian postmenopausal women. METHODS: A cross-sectional study was performed in 307 women over 40 years of age who were receiving care at the gynecology clinic of the Center for Women's Integrated Healthcare (CAISM), ABC School of Medicine. All these women had been amenorrheic for at least 12 months and had undergone mammography in the preceding 12 months. Cardiovascular disease and its subtypes were evaluated, as well as its association with BAC. Means and standard deviations, absolute frequencies and percentages were calculated, and univariate analysis and multiple logistic regression were performed. RESULTS: The mean age of the patients was 55.2 +/- 6.8 years; age at menopause was 48.5 +/- 4 years. Time since menopause was 80.2 +/- 75.4 months; 96.1% of the patients were non-smokers and 46.3% were using hormone therapy. Of the patients, 33.6% had systemic arterial hypertension, 4.9% had diabetes mellitus and 5.2% had hypercholesterolemia. The mean body mass index was 27.3 +/- 4.3 kg/m(2). CVD was found in 6.8% and BAC in 8.5% of the women. Significantly more women with BAC had CVD compared to the women who did not have this condition (23.1% vs. 5.3%, p = 0.0006). BAC was associated with an odds ratio of 8.13 (95% confidence interval 2.68-24.64) for predicting CVD. CONCLUSIONS: In postmenopausal women, breast arterial calcification may represent a higher likelihood of cardiovascular disease.
