Chemical characteristics of groundwaters at two massive sulphide deposits in an area of previous mining contamination, South Iberian Pyrite Belt, Spain

A detailed chemical study of groundwater was carried out to elucidate the processes controlling the oxidation and dissolution of sulphide minerals at two massive sulphide deposits in the Iberian Pyrite Belt (IPB), i.e. the mined La Zarza deposit and the unmined Masa Valverde deposit. It was found that major-element compositions varied according to the hydrological regime, La Zarza being in a relatively high area with groundwater recharge (and disturbance due to the human factor) and Masa Valverde being in a relatively low area with groundwater discharge. The variations mainly concem pH, Eh, S04 and Na concentrations. Metal concentrations were determined (a) by ICP-MS after filtration, and (b) in sorne cases by voltammetric measurement of Cu, Pb, Zn, Cd and Mn using the Voltammetric In situ Profiling (VIP) System, which allows detection of only the mobile fractions of trace elements (i.e., free metal ions and small labile complexes a few nanometers in size). If one compares the results obtained by each of the two methods, it would appear that the groundwater shows significant enhancement of metal solubility through complexing with organic matter andlor adsorption onto colloids andlor small particles. In areas of sulphide oxidation, however, this solubility enhancement decreases according to Cu> Zn>Cd>Pb. Dnder very low redox conditions, the attained metal concentrations can be several orders of magnitude (up to 108-1 09 for Cu and 102-103 for Pb) larger than those expected from equilibrium with respect to sulphide minerals as calculated with the EQ3NR geochemical code; Zn concentrations, however, are close to equilibrium with respect to sphalerite. The implication of these results is discussed with respect both to mineral exploration and to environmental issues

In-situ trace metal (Cd, Pb, Cu) speciation along the Po River plume (Northern Adriatic Sea) using submersible systems

Highlights • In-situ trace metal speciation in the Adriatic Sea by submersible voltammetric sensors • Metal species distribution mainly affected by Po River outflow. • Metal dynamic concentrations below legal limits • Cu dynamic concentrations toxic to sensitive phytoplankton Abstract Information on the distribution and speciation of trace metals is of critical importance for our ability to interpret the links between the bioavailability and uptake of an element, and its biogeochemical cycle in coastal environments. Within the framework of the European Project “In-situ automated Monitoring of Trace metal speciation in Estuaries and Coastal zones in relation with the biogeochemical processes (IMTEC)”, the chemical speciation of Cd, Pb and Cu was carried out along the Po River plume in the period 27 October – 2 November 2002. During the cruise, five Voltammetric In-situ Profiling systems and one Multi Physical Chemical Profiler, as well as conventional voltammetric instruments, were successfully applied in order to evaluate the distribution of Cd, Pb and Cu between different fractions (free ion, dynamic, colloidal, dissolved and particulate fractions) and to assess the evolution of these fractions during estuarine mixing and in the water column. Dynamic concentrations were 0.05–0.2 nmol L−1 Cd, 0.02–0.2 nmol L−1 Pb, and 0.15–4.0 nmol L−1Cu. Cd was mainly present as dynamic fraction (40–100% of the dissolved Cd). High proportions of Pb (~70%) and Cu (~80%) were present as colloids probably of biogenic origin. Principal components analysis reveals a strong influence of the Po River discharge on the spatial and vertical distributions of metal species. Almost all the metal fractions globally decreased following the salinity gradient. Metal concentrations are far below (at least one order of magnitude lower) the Environmental Quality Standard established by the Italian law. However, the Cu dynamic fraction showed concentrations likely to be toxic to sensitive phytoplankton community and to have negative effects on larva development of coastal macroinvertebrate species (toxicity data extracted from literature)

Satisfaction and compliance in hormonal contraception: the result of a multicentre clinical study on women's experience with the ethinylestradiol/norelgestromin contraceptive patch in Italy

<p>Abstract</p> <p>Background</p> <p>For many women finding the right contraceptive method can be challenging and consistent and correct use over a lifetime is difficult. Even remembering to take a birth control pill every day can be a challenge. The primary objective of this study was to evaluate women's experience with a weekly ethinylestradiol/norelgestromin contraceptive patch (EE/NGMN patch), given new technologies recently developed in hormonal contraception to increase women's options in avoiding daily dosing.</p> <p>Methods</p> <p>In 24 Italian sites, 207 women received the EE/NGMN patch for up to 6 cycles. At study end, overall satisfaction and preference, as well as compliance, efficacy and safety, were evaluated.</p> <p>Results</p> <p>175 women (84.5%) completed the study. The overall satisfaction rate was 88%; convenience and once-a-week frequency of the patch were especially appreciated. At baseline, 82 women (39.4%) were using a contraceptive method, mainly oral contraceptives and barrier methods, but only 45.1% were very satisfied/satisfied; after 6 months with the patch, 86.3% of this subset was very satisfied/satisfied. Considering the method used in the 3 months before the study entry, 78.1% strongly preferred/preferred the patch, for convenience (53.9%), ease of use/simplicity (28.9%), fewer (9.2%) and less severe (2.6%) side effects. Compliance was very high: 1034/1110 cycles (93.2%) were completed with perfect compliance and the mean subject's compliance score was 90%. One on-therapy pregnancy occurred. The patch was safe and well tolerated: adverse events frequency was low, with predominantly single reports of each event. Most of them started and subsided during cycle 1.</p> <p>Conclusion</p> <p>This study demonstrated that the EE/NGMN patch is associated with high satisfaction levels and excellent compliance. At study end, the majority of women indicated that they would continue using the patch.</p

Vulvar pain: The revealing scenario of leading comorbidities in 1183 cases

Objectives: This study set out to investigate the epidemiological characteristics and comorbidities of chronic vulvar pain. Secondary goals were to identify the preferred approaches for managing vulvodynia in Italy. Study Design: A cross-sectional study (the VuNet -Vulvodynia Network project) was performed in consecutive female patients with chronic vulvar pain attending 21 Italian medical centers (public hospitals, university clinics and private outpatient services) in the period December 2016 to November 2018. Study data were entered by healthcare professionals in a special web-based medical record system (PRIDE- Progetto Rete Italiana Dolore vulvarE). These data covered epidemiological aspects, demographic characteristics, obstetric and gynecological history, presence and duration of current and/or past symptoms, associated disorders, details of physical examination and treatment approaches. Results: A total of 1183 subjects with a diagnosis of chronic vulvar pain were included in the study. The main reason for consultation was superficial dyspareunia, present in 64.2 % of the women. 43.4 % of the sample reported comorbid sexual disorders (of desire in 22.1 % and arousal in 21.3 %). 48.3 % of the patients reported prolonged pain lasting between one and five years. Factors associated with vulvar pain included a relatively high family history of diabetes mellitus (father = 8.6 %; mother = 8.4 %), recurrent vulvovaginal candidiasis (32 %), and urinary tract infections (37.4 %: recurrent cystitis in 19.5 % and post-coital cystitis in 17.9 %). Irritable bowel syndrome (28 %), constipation (23.5 %), headache (25.7 %: migraine in 18.0 % and menstrual headache in 7.7 %), allergies (17.5 %: food allergies in 10.1 %, respiratory allergies in 7.4 %), anxiety (15.0 %), dyschezia (11.7 %), invalidating dysmenorrhea/endometriosis (11.1 %), and major depression (7.6 %) were also reported. Vestibulodynia was diagnosed in 837 of the 1183 patients (70.8 %) and generalized vulvodynia in 323 (27.3 %). Notably, 69.1 % of the patients stated that previous therapies had not changed their pain. Conclusions: The diagnoses of vestibulodynia and vulvodynia must be considered in patients with chronic vulvar pain. The VuNet study contributes to a more comprehensive reading of the predisposing, precipitating and maintaining factors that contribute to vulvar pain, and of the key comorbidities

Multi physical-chemical profiler for real-time automated in situ monitoring of specific fractions of trace metals and master variables

State of the art in the development of a novel Multi Physical-Chemical profiler (MPCP system) for simultaneous, autonomous, in situ measurements of three environmentally relevant specific fractions of trace metals as well as master variables in natural waters is presented. It has been designed using advanced voltammetric microsensors, microprocessor and telemetry technology. A detailed description of the system is given and examples of environmental applications for in situ measurements in sea water are reported. The results indicate that the system is reliable and that in situ measurements of the three specific fractions of trace metals can be achieved down to concentrations at the ppt level using Square Wave Anodic Stripping Voltammetry (SWASV)

Six Out of Ten Women with Recurrent Urinary Tract Infections Complain of Distressful Sexual Dysfunction - A Case-Control Study

Uncomplicated recurrent urinary tract infections (rUTIs) are common among reproductive-aged women. We aimed to assess the prevalence and predictors of sexual dysfunction (FSD) in a cohort of women with rUTIs and compare their psychometric scores to those of matched controls. Data from 147 rUTIs women and 150 healthy controls were analysed. Participants completed the International Prostatic Symptoms Score (IPSS), the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (SDS). Descriptive statistics and logistic regression models tested prevalence and predictors of distressful FSD. Women with rUTIs had lower FSFI scores (p < 0.001) and a greater proportion of pathological FSFI (78.9% vs. 21.4%; p < 0.001) and SDS scores (77.8% vs. 21.4%; p < 0.001) than controls. Of rUTIs patients, 88 (60%), 77 (52.2%), and 75 (51.1%) reported pathological scores for FSFI-pain, lubrication and arousal, respectively; moreover, 64% had concomitant pathological FSFI and SDS scores. Age, IPSS severity, rUTIs, a history of 656 UTIs/year and a history of constipation were independent predictors of pathologic FSFI and SDS (all p 64 0.05). In conclusion, up to 80% of women with rUTIs showed pathologic FSFI and SDS scores, with 60% reporting scores suggestive of distressful FSD. Having 656 UTIs/year and a history of constipation independently predicted distressful FSD

Hormone therapy and sleep quality in women around menopause

Objective: To obtain data on sleep quality in women attending menopause clinics in Italy. Design: A cross-sectional study was conducted on the sleep quality of postmenopausal women attending a network of first-level outpatient menopause clinics in Italy for general counseling about menopause or treatment of its symptoms. Eligible for the study were women observed consecutively during the study period with natural or spontaneous menopause. All participating centers enrolled women into the study who had never used hormone therapy (HT) (group 1, 819 women), current users of transdermal estrogens with or without progestins (group 2, 819 women), and current users of oral estrogens with or without progestins (group 3, 790 women). The women were asked about their quality of sleep using the Basic Nordic Sleep Questionnaire, their quality of life using the Short Form-12 questionnaire, and the intensity of hot flushes using a visual analogue scale. Results: Women in groups 2 and 3 tended to report difficulties in sleeping less often than those in group 1. For example, never users of HT more frequently reported sleeping poorly and needed more time to sleep or had problems falling asleep; these differences were significant (P < 0.05). Otherwise, no difference emerged from the Basic Nordic Sleep Questionnaire between women in groups 2 and 3. Conclusions: This study gives support to the suggestion that HT improves the quality of sleep. The effect was similar in women taking oral or transdermal therapy with or without progestins
