Metabolomic profiling in blood from umbilical cords of low birth weight newborns
2012
AbstractBackgroundLow birth weight has been linked to an increased risk to develop obesity, type 2 diabetes, and hypertension in adult life, although the mechanisms underlying the association are not well understood. The objective was to determine whether the metabolomic profile of plasma from umbilical cord differs between low and normal birth weight newborns.MethodsFifty healthy pregnant women and their infants were selected. The eligibility criteria were being born at term and having a normal pregnancy. Pairs were grouped according to their birth weight: low birth weight (LBW, birth weight < 10thpercentile, n = 20) and control (control, birth weight between the 75th-90thpercentiles, n…
Menstrual disorders and subfertility in Spanish hairdressers
2009
Abstract Objective Hairdressing is associated with adverse effects on reproductive health. This research investigates whether female hairdressers have increased risks of subfertility and menstrual disorders. Study design Cross sectional study. Participants were all female hairdressers below 50 years of age ( n = 310) working in registered hairdressing salons in Alicante, Spain and a control group comprising female shop assistants and office workers ( n =310). Menstrual disorders were defined as any of five menstrual cycle characteristics: short cycles, long cycles, irregular cycles, not experiencing a period for more than 6 weeks (missed period), and bleeding or spotting between periods (…
Serum interleukin-6 levels are elevated in women with minimal-mild endometriosis.
2006
BACKGROUND: There is a need for a reliable marker of endometriosis, especially in early stages of peritoneal disease during which imaging is not effective. The use of serum interleukin (IL)-6 as a marker is controversial. To readdress the matter, patients undergoing laparoscopy were prospectively evaluated for serum IL-6 levels. MATERIALS AND METHODS: A total of 119 women 31 years old who underwent laparoscopy were divided into groups: control patients (n = 38) with no pathologic findings; endometriosis sufferers (n = 47) with minimal-mild (MM, n = 11) or moderate-severe (MS, n = 36) endometriosis; uterine myomas (n = 13) and benign ovarian pathologies (n = 21). Blood was drawn on cycles da…
The effect of exposure to radiofrequency fields on cancer risk in the general and working population: A protocol for a systematic review of human obs…
2021
Highlights • RF-EMF was classified by IARC as possibly carcinogenic to humans (2B) in May 2011 • A systematic review of all subject-relevant epidemiological studies is now needed. • A detailed protocol ensures the review's transparency, utility and credibility. • Original study validity will be evaluated with a customized OHAT risk of bias tool. • Internal coherence and external plausibility will inform conclusions.
Maternal caesarean section infection (MACSI) in Sierra Leone: a case-control study.
2020
Sierra Leone is the country with highest maternal mortality and infections are the underlying cause in 11% of maternal deaths, but the real burden remains unknown. This study aims to determine the incidence and risk factors of surgical site infection (SSI) post-caesarean section (CS) in women admitted to Princess Christian Maternity Hospital (PCMH) in Freetown, Sierra Leone. A prospective case-control (1:3 ratio) study was implemented from 1 May 2018 to 30 April 2019 and 11 women presenting with suspected or confirmed infection post-CS were screened for inclusion as a case. For each case, three patients undergoing CS on the same day and admitted to the same ward, but not presenting with SSI…
Uterine fibroids risk and history of selected medical conditions linked with female hormones
2004
To understand the role of several medical conditions on the risk of uterine fibroids, we analysed the findings of a large case-control study. Cases were 843 women aged 54 or less (median age 43 years, range 21-54) with histologically confirmed uterine fibroids, whose clinical diagnosis dated back no more than 2 years. Indications for surgery were recurrent menorrhagia or ultrasound evidence of fibroids larger than 10 cm in diameter. Controls were 1557 women aged 54 years or less of comparable quinquennia of age (median age 43 years, range 21-54) who had not undergone hysterectomy and were admitted for acute, non-gynecologic, non-hormonal, non-neoplastic conditions to a network of hospitals …
Selected food intake and risk of endometriosis.
2004
Background: To offer data on the relationship between diet and risk of pelvic endometriosis, we analysed data collected in the framework of two case-control studies. Methods: Data from two case-control studies conducted in Northern Italy between 1984 and 1999 were combined. Cases were 504 women aged < 65 years (median age 33 years, range 20-65) with a laparoscopically confirmed diagnosis of endometriosis, admitted to a network of obstetrics and gynaecology departments in Milan, Brescia and Pavia. Controls were 504 women (median age 34 years, range 20-61) admitted for acute non-gynaecological, non-hormonal, non-neoplastic conditions. Results: Compared to women in the lowest tertile of intake…
Anticipatory effects of food exposure in women diagnosed with bulimia nervosa.
2002
Objective. To investigate cephalic phase responses (CPRs) in women diagnosed with bulimia nervosa and to test the assumption that eating disordered individuals respond with more marked CPRs and higher increases in psychophysiological arousal to the presentation of food cues. Method. Thirteen female inpatients diagnosed with bulimia nervosa were compared to 15 non-eating disordered female volunteers. Participants were exposed to their preferred binge food in a single laboratory session with the possibility to eat immediately after the exposure trial. Results. The results show greater salivation responses to food exposure and lower sympathetic arousal in patients diagnosed with bulimia nervos…
Diet and risk of seromucinous benign ovarian cysts
2003
Abstract Objective : To analyze the relation between selected dietary indicators and the risk of seromucinous benign ovarian cysts. Study design : We used data from a case–control study on risk factors for benign ovarian cysts conducted in Italy between 1984 and 1994. Cases included 225 women with a histologically confirmed diagnosis of benign seromucinous ovarian neoplasm dating back no more than 2 years. Controls were 450 women below the age of 65 years admitted for acute non-gynecological, non-hormonal, non-neoplastic conditions. Results : Women with seromucinous cysts reported more frequent consumption of beef and other red meat and cheese and less frequent consumption of green vegetabl…
Coffee drinking and risk of preterm birth
2006
Objectives: We analysed the association between coffee drinking before and during the three trimesters of pregnancy and the risk of preterm birth of babies normal for gestational age (NGA) or small for gestational age (SGA). Methods: Case-control study conducted in University clinics of North Italy. Cases were 502 women who delivered at < weeks of gestation. The controls included 1966 women who gave birth at term (≥37 weeks of gestation) to healthy infants on randomly selected days at the hospitals where cases had been identified. Results: There was inverse association for coffee consumption in the third trimester of pregnancy in SGA cases compared to NGA (heterogeneity test between OR: χ12…
