RESUMO

People are daily exposed to multiple endocrine disruptor compounds (EDCs) that may interfere with different molecular and cellular processes, promoting a potential estrogenic, androgenic, or anti-androgenic state. However, most epidemiological studies attempting to establish relationships between EDCs exposure and health effects are still considering individual compounds. A few studies have shown associations between exposure to individual non-persistent EDCs and sperm DNA fragmentation (SDF) in different male populations. Thus, the aim of this study was to investigate associations between combined exposure to non-persistent EDCs and SDF index in young men. A cross-sectional study was conducted with 158 healthy university students from Southeaster Spain. The participants provided spot urine and semen samples on the same day. The concentrations of urinary bisphenol A (BPA), benzophenones [2,4-dihydroxybenzophenone (BP-1); 2,2',4,4'-tetrahydroxybenzophenone (BP-2), 2-hydroxy-4-methoxybenzophenone (BP-3), 2,2'-dihydroxy-4-methoxybenzophenone (BP-8), 4-hydroxybenzophenone (4OHBP)], and parabens (methylparaben, ethylparaben, propylparaben, butylparaben) were measured by dispersive liquid-liquid microextraction and ultrahigh-performance liquid chromatography with tandem mass spectrometry detection. SDF was analysed using a Sperm Chromatin Dispersion test. Statistical analyses were carried out using Bayesian Kernel Machine Regression models to evaluate associations between combined exposure to these compounds and SDF index while adjusting by relevant covariates. The increase in urinary concentration of 4OHBP was found to be the most important contributor to the negative association between urinary EDCs concentrations and SDF index, being of -5.5 % [95 % CI: -10.7, -0.3] for those in percentile 50, and - 5.4 % [95 % CI: -10.8, -0.1] for those in percentile 75. No significant associations were observed between other EDCs and SDF index. Our findings show that urinary 4OHBP levels may be associated with a decrease in the SDF index. Nonetheless, the effects we observed were likely to be small and of uncertain clinical significance. Further research is needed to replicate our findings in other male populations.

RESUMO

OBJECTIVE: Evaluate the association between AGD and the risk of PCa. METHODS: Incident case-control study, conducted on 153 patients. All patients underwent prostate biopsy for abnormal digital rectal exam and/or prostate antigen elevation. Two variants of AGD [anus to scrotum base (AGDas) and anus to dorsal insertion of penis (AGDap) were measured. Student's t-test was used to analyze continuous variables and chi-square for discrete variables. Differences in AGD (raw and adjusted) measures between cases and controls were assessed using the ANCOVA test. RESULTS: There is significant association between the diagnose of PCa and both AGD, patients diagnosed with PCa had both AGD measures shortened, in the crude and the full adjusted models. CONCLUSIONS: This research suggests that the same gestational environmental exposures, could represent a weak androgen signaling and may also have an increased risk of prostate cancer.

RESUMO

AIM: Establish the influence of the terminal or nonterminal position of High Efficiency Particulate Air (HEPA) filters in the Heating, Ventilation, and Air Conditioning (HVAC) system on the presence of airborne fungi in controlled environment rooms. BACKGROUND: Fungal infections are an important cause of morbidity and mortality in hospitalized patients. METHODS: This study was realized from 2010 to 2017, in rooms with terminal and nonterminal HEPA filters, in eight Spanish hospitals. In rooms with terminal HEPA filters, 2,053 and 2,049 samples were recollected, and in rooms with nonterminal HEPA filters, 430 and 428 samples were recollected in the air discharge outlet (Point 1) and in the center of the room (Point 2), respectively. Temperature, relative humidity, air changes per hour, and differential pressure were recollected. RESULTS: Multivariable analysis showed higher odds ratio (OR) of airborne fungi presence when HEPA filters were in nonterminal position (OR: 6.78; 95% CI [3.77, 12.20]) in Point 1 and (OR: 4.43; 95% CI [2.65, 7.40]) in Point 2. Other parameters influenced airborne fungi presence, such as temperature (OR: 1.23; 95% CI [1.06, 1.41]) in Point 2 differential pressure (OR: 0.86; 95% CI [0.84, 0.90]) and (OR: 0.88; 95% CI [0.86, 0.91]) in Points 1 and 2, respectively. CONCLUSIONS: HEPA filter in terminal position of the HVAC system reduces the presence of airborne fungi. To decrease the presence of airborne fungi, adequate maintenance of the environmental and design parameters is necessary in addition to the terminal position of the HEPA filter.

RESUMO

AIM: Determine the utility of the Periodic Environmental Biosecurity Assessment Program (PEBAP) in achieving clean air as measured by the number of colony-forming units (CFU) of fungi and bacteria in the air. BACKGROUND: There is no international consensus on the sampling frequency, the recommended limits for microorganisms in the air nor on the usefulness of routine microbiological air monitoring of hospitals. METHODS: During the PEBAP, data were recollected between 2010 and 2017 in eight hospitals in southeast Spain. Air samples were collected in very high risk rooms (VHRRs) and high risk rooms (HRRs), unoccupied, using active sampling methods. Temperature, relative humidity, air changes per hour (ACH), and differential pressure were measured. When limits of CFU of opportunistic fungi and bacteria established in the PEBAP were exceeded, corrective measures were adopted. RESULTS: We found a reduction (p < .01) of percentage of air samples with fungi growth throughout the years of PEBAP in all rooms. Aspergillus was the most frequent opportunistic fungus. We found a high compliance of the standards of CFU of bacteria in HRR, and the percentage of compliance in VHRR was lower than in HRR in all years. Differences in environmental and design parameters were statistically significant (p < .05) between rooms, except for ACH. CONCLUSIONS: PEBAP resulted in a useful tool to maintain and improve air quality in hospitals. The control of environmental biosecurity requires a multidisciplinary approach from preventive medicine, engineering, and cleaning services. Aspergillus is the most frequent opportunistic fungus in southeast Spain.

RESUMO

In this report, the measurement of salivary biomarkers as an aid for diagnosis of equine gastric ulcer syndrome (EGUS) was studied. A comprehensive panel of 23 salivary analytes was measured in the saliva of horses affected by EGUS and compared to healthy animals and horses with other diseases clinically similar to EGUS but with a negative diagnosis at gastroscopic examination. A total of 147 horses were included in the study and divided into heathy population (n = 12), the EGUS group (n = 110), and the group of horses with other diseases (n = 25). From the 23 analytes studied, 17 showed increased values in EGUS horses when compared to healthy ones, and uric acid, triglycerides, and calcium were significantly increased in horses with EGUS compared to the group of other diseases. The receiver operating characteristic curve analyses showed a modest but significant discriminatory power of those three analytes to identify EGUS from other diseases with similar symptoms. The discriminatory power enhanced when the results of the three analytes were combined. In conclusion, the results showed that selected salivary analytes could have potential use as biomarkers in horses with EGUS.

RESUMO

Introducción: Estudios recientes muestran un aumento del uso de antidepresivos en menores de 18 años, aunque pocos de ellos cuentan con indicación en este grupo de edad. El objetivo de este estudio es calcular la prevalencia anual del uso de antidepresivos en niños y adolescentes y revisar la adecuación de la prescripción a las indicaciones actuales. Métodos: Estudio de prevalencia de la utilización de antidepresivos en menores de 18 años a partir de los registros de la Base de datos para la Investigación Farmacoepidemiológica en Atención Primaria (BIFAP) durante el periodo 2013-2018, considerando al menos una prescripción por año para un mismo paciente. Resultados: La prevalencia de prescripción de antidepresivos entre los pacientes de la cohorte BIFAP ha aumentado de 2013 (7,97 prescripciones/1.000 pacientes) a 2018 (8,87 prescripciones/1.000 pacientes) en la mayoría de los grupos y en ambos sexos. El sexo femenino suma la mayoría de las prescripciones, superando al masculino en hasta 2,5 puntos en las tasas generales. En menores de 13 años la tendencia se invierte y los antidepresivos predominan en los chicos. La prevalencia de las prescripciones aumenta con la edad de los pacientes, igual que la proporción de tratamientos fuera de ficha técnica. El empleo de fármacos sin indicación disminuye con el transcurso del tiempo. Conclusiones: Observamos un aumento gradual en la prevalencia de prescripción de antidepresivos en menores de 18 años, preponderante en el sexo femenino. La elevada proporción de uso de estos fármacos sin indicación autorizada exige profundizar en el balance beneficio-riesgo y en alternativas de tratamiento más seguras. (AU)


Introduction: Recent studies show an increase in the use of antidepressants in minors (younger than 18 years), although few antidepressants are indicated for this age group. The aim of our study was to calculate the annual prevalence of antidepressant use in children and adolescents and to review the adherence of prescription to current indications. Methods: Study of the prevalence of antidepressant use in minors based on the records of the Electronic Database for Pharmacoepidemiologic Studies in Primary Care (BIFAP) of Spain for the 2013–2018 period, considering at least one prescription per year for each patient. Results: The prevalence of antidepressant prescription in patients from the BIFAP cohort increased between 2013 (7.97 prescriptions per 1000 patients) and 2018 (8.87 prescriptions per 1000 patients), in most groups and in both sexes. In this period, female patients received the most prescriptions, surpassing prescriptions in male patients by up to 2.5 points in the overall rates. In patients younger than 13 years, this trend was inverted and antidepressant use was higher in male patients. The prevalence of prescription rose with increasing patient age, as did the proportion of off-label prescriptions. The use of off-label medication decreased over time. Conclusions: There was a gradual increase in the prevalence of antidepressant prescription in minors younger than 18 years, with a predominance of the female sex. The high proportion of unapproved medication use in this age group calls for more thorough investigation of the risk–benefit balance of these treatments and of safer treatment alternatives. (AU)

RESUMO

BACKGROUND: Cystic fibrosis (CF) has a vast and heterogeneous mutational spectrum in Europe. This variability has also been described in Spain, and there are numerous studies linking CFTR variants with the symptoms of the disease. Most of the studies analysed determinate clinical manifestations or specific sequence variants in patients from clinical units. Others used registry data without addressing the genotype-phenotype relationship. Therefore, the objective of this study is to describe the genetic and clinical characteristics of people with CF and to analyse the relationship between both using data from the rare disease registry of a region in southeastern Spain. METHODS: A cross-sectional study was carried out in people with a confirmed diagnosis of CF registered in the Rare Diseases Information System (SIER) of the Region of Murcia (Spain). The patients were classified into two genotypes according to the functional consequence that the genetic variants had on the CFTR protein. RESULTS: There were 192 people diagnosed with CF reported in the Region of Murcia as of 31 December 2018. Seventy-six genotypes and 49 different variants were described, with c.1521_1523delCTT (p. Phe508del) being the most common in 58.3% of the CF patients and 37.0% of the alleles. In addition, 67% of the patients were classified as a high-risk genotype, which was associated with a lower percentage of FEV1 (OR: 5.3; 95% CI: 1.2, 24.4), an increased risk of colonization by Pseudomonas aeruginosa (OR: 7.5; 95% CI: 1.7, 33.0) and the presence of pancreatic insufficiency (OR: 28.1; 95% CI: 9.3, 84.4) compared to those with a low-risk genotype. CONCLUSIONS: This is the first study in Spain that describes the mutational spectrum and its association with clinical manifestations in patients with CF using data from a rare disease registry. The results obtained allow planning for the health resources needed by people with this disease, thus contributing to the development of personalized medicine that helps to optimize health care in CF patients.

RESUMO

Endocrine disrupting chemicals (EDCs) set a public health risk through disruption of normal physiological processes. The toxicoepigenetic mechanisms of developmental exposure to common EDCs, such as bisphenol A (BPA), are poorly known. The present study aimed to evaluate associations between perinatal maternal urinary concentrations of BPA, bisphenol S (BPS) and bisphenol F (BPF) and LINE-1 (long interspersed nuclear elements) and Alu (short interspersed nuclear elements, SINEs) DNA methylation levels in newborns, as surrogate markers of global DNA methylation. Data come from 318 mother-child pairs of the `Nutrition in Early Life and Asthma´ (NELA) birth cohort. Urinary bisphenol concentration was measured by dispersive liquid-liquid microextraction and ultrahigh performance liquid chromatography with tandem mass spectrometry detection. DNA methylation was quantitatively assessed by bisulphite pyrosequencing on 3 LINEs and 5 SINEs. Unadjusted linear regression analyses showed that higher concentration of maternal urinary BPA in 24th week's pregnancy was associated with an increase in LINE-1 methylation in all newborns (p = 0.01) and, particularly, in male newborns (p = 0.03). These associations remained in full adjusted models [beta = 0.09 (95 % CI = 0.03; 0.14) for all newborns; and beta = 0.10 (95 % CI = 0.03; 0.17) for males], including a non-linear association for female newborns as well (p-trend = 0.003). No associations were found between maternal concentrations of bisphenol and Alu sequences. Our results suggest that exposure to environmental levels of BPA may be associated with a modest increase in LINE-1 methylation -as a relevant marker of epigenomic stability- during human fetal development. However, any effects on global DNA methylation are likely to be small, and of uncertain biological significance.

RESUMO

BACKGROUND: There has been a decrease in sperm concentration in recent years. Concurrently, there were important dietary changes, including an increase in sugar-sweetened beverage intake (SSB). The relation between SSB and male reproduction functions in humans are barely described in the literature. METHODS: Cross-sectional study with 209 participants (18-23 years old) recruited during one year in Murcia, Spain. All men provided semen and blood samples the same day. SSB consumption was evaluated using a 101-item validated food frequency questionnaire. Reproductive hormones were analysed from serum samples, obtaining levels of follicle-stimulating hormone, inhibin B, luteinizing hormone, estradiol, and testosterone. The evaluation of semen analysis followed the WHO guidelines and consisted of seminal volume, sperm concentration, total sperm count, percentage of morphologically normal sperm, and percentage of motile sperm. SSB intake association with semen parameters and hormone levels were examined using multiple linear regression. RESULTS: Men in the highest quartile of the SSB intake had a higher percentage of morphologically normal sperm, 37.4% [6.1, 68.3] (p, trend=0.047) and higher estradiol levels (9.5% [-3.5, 22.5] (p, trend=0.047) than those in the first quartile. SSB intake was unrelated to other semen quality parameters or reproductive hormone levels. CONCLUSIONS: Our results indicate that sperm morphology and estradiol levels may be associated with sugar-sweetened beverage intake. These findings might be explained by physiological metabolism homeostasis, though more studies are required to confirm these results and draw conclusions in other male populations.

RESUMO

RESEARCH QUESTION: Do women with polycystic ovary syndrome (PCOS) have a different fat intake pattern to women without PCOS? DESIGN: Case-control study of 276 women between 20 and 35 years old from the Murcia region of Spain. Cases (n = 121) attended the Department of Gynaecology and Obstetrics of the University Clinical Hospital and were diagnosed with PCOS using Rotterdam criteria. Controls (n = 155) were women without PCOS attending the gynaecological outpatient clinic for routine gynaecological examinations. Data from clinical, gynaecological and analytical examinations were collected, including a food frequency questionnaire. Associations between fat intake and presence of PCOS and its phenotypes were examined using multiple logistic regression, adjusting for potential confounding factors. RESULTS: Although no association was found between fatty acid intake and PCOS, significant associations were observed for some PCOS phenotypes. The PCOS phenotype characterized by hyperandrogenism + oligo/amenorrhoea + polycystic ovarian morphology ('H+O+POM') was significantly associated with a higher intake of polyunsaturated fat (odds ratio [OR] 4.0; 95% confidence interval [CI] 1.1-14.2; fourth quartile of highest intake [Q4] versus lowest intake quartile as reference [Q1]) and omega-6 fatty acids (OR 3.5; 95% CI 1.01-12.4; Q3 versus Q1). The 'H+O' phenotype was positively associated with saturated fat intake (OR 6.9; 95% CI 1.1-41.6; Q4 versus Q1). CONCLUSION: This exploratory study suggests that higher intakes of specific fatty acids are related to some PCOS phenotypes although no association was found for PCOS on a global basis. It is recommended that studies with larger sample size be performed to further explore these associations, thus contributing to establishing recommendations about fat intake adapted to different PCOS phenotypes.

RESUMO

Anthropometric assessment during pregnancy is a widely used, low-technology procedure that has not been rigorously evaluated. Our objective is to investigate fat mass distribution during pregnancy by examining changes in anthropometrics measures, in order to evaluate the reliability of these measures. An observational, longitudinal, prospective cohort study was performed in 208 pregnant women. Anthropometric measurements were taken following the ISAK protocol during the three trimesters and a generalized linear model for repeated measures was used to evaluate differences. Variability was assessed using the coefficient of variation, and Propagated Error (PE) was used to sum of skinfold thicknesses (SFT). SFT showed a general increase in fat mass during the three trimesters of pregnancy (∑SFT7 p = 0.003), and was observed in specific anatomical locations as well: arms (∑Arm SFT, p = 0.046), trunk (∑Trunk SFT, p = 0.019), legs (∑Leg SFT, p = 0.001) and appendicular (∑Appendicular SFT, p = 0.001). Anthropometric measures for skinfold thickness were taken individually during pregnancy and were reliable and reproducible during the three trimesters, which could help to prevent adverse pregnancy outcomes.

RESUMO

Paracetamol is the one of the most commonly used medications during pregnancy. However, its potential antiandrogenic effect has been suggested. The objective of this study was to evaluate associations between maternal paracetamol use during pregnancy and anogenital distance (AGD) in male newborns from a Spanish birth cohort. The study included two hundred and seventy-seven mother-male child pairs with self-reported paracetamol use and frequency during each trimester of pregnancy. AGD measurements were taken employing standardized methods. The associations between maternal paracetamol use and AGD measures were evaluated using linear regression models, adjusting for potential confounders and covariates. Overall, 61.7% of pregnant women consumed paracetamol at any time of pregnancy with an average of 9.43 (SD = 15.33) days throughout pregnancy. No associations between the maternal use of paracetamol or its frequency and AGD measures among different trimesters or during the whole pregnancy were found in the adjusted final models. A non-differential misclassification error may have occurred-the recall of paracetamol intake independent of AGD measurements-introducing bias towards the null hypothesis. Nevertheless, the current evidence suggests that paracetamol might have a potential antiandrogenic effect especially in the early stages of fetal development. Thus, it would be highly recommendable to pursue further studies to elucidate the potential effects of paracetamol in human perinatal health and its use among pregnant women.

RESUMO

BACKGROUND: Bisphenol A (BPA) is one of the most common endocrine disruptor compounds in our environment, promoting a xenoestrogenic state. Numerous studies have shown a relationship between exposure to BPA and male infertility problems. Spermatic DNA integrity is a critical factor for the correct transmission of paternal genetic material to the embryo. However, only a very few studies have investigated the association between urinary BPA concentrations and human sperm DNA fragmentation (SDF). METHOD: Cross-sectional study conducted with 158 healthy university students (18-23 years), recruited between 2010 and 2011 in the Region of Murcia (Spain). The subjects provided urine and semen samples on a single day. Urinary BPA concentrations were measured by dispersive liquid-liquid microextraction and ultrahigh performance liquid chromatography with tandem mass spectrometry detection, and SDF analysed using the Sperm Chromatin Dispersion test. Statistical analyses were made using linear regression adjusting for potential covariates and confounding factors. RESULTS: No association was found between urinary BPA concentrations and SDF index in the total group. However, in the subgroup of men with SDF index> 30%, significant positive associations across quartiles (p-trend=0.02) and as a continuous BPA levels were observed (ß = 0.055, 95%, CI: 0.002; 0.108). CONCLUSION: Our results show that, within the subgroup of men with relatively high SDF index, the higher the concentration of BPA the greater the SDF index. Nonetheless, more studies are required to confirm these results and draw conclusions in other male populations.

RESUMO

AIM: The objective of this study was to evaluate associations between maternal concentrations of 25-hydroxyvitamin D (25(OHD)) and birth outcomes: mode of delivery and episiotomy rate. DESIGN AND METHODS: One hundred and seventeen pregnant women were enrolled in an observational, longitudinal, prospective cohort study. Multivariable linear regression analyses were performed to assess relationships between maternal 25(OHD) concentrations and mode of delivery. To account for systematic temporal variation in 25(OHD), a cosinor model to the data was fitted. RESULTS: No significant statistical associations were found between adjusted maternal 25(OHD) concentrations and risk of eutocic vaginal delivery, instrumented delivery (OR 1.05 [95% CI: 0.97-1.13]), primary Caesarean section (OR 0.99 [95% CI: 0.88-1.11]) or Caesarean section for any other causes (OR 1.04 [95% CI: 0.95-1.14]). High 25(OHD) levels tended to show a protective effect on performance of episiotomy, without reaching statistical significance (OR 0.36 [95% CI: 0.09, 1.37]).

RESUMO

To describe whether polycystic ovary syndrome (PCOS) phenotypes vary in their body composition and skinfold (SKF) thicknesses and if they differ from women without PCOS, a preiminar case-control study was performed. A total of 117 cases were diagnosed using the Rotterdam criteria. Gynecological examinations and transvaginal ultrasound were performed in all women (266 women). Anthropometric measurements including SKF thickness were taken according to the restricted profile protocol of the international standards for the anthropometric evaluation according to the International Society of the Advancement of Kinanthropometry (ISAK). Women with PCOS had higher body mass index and percentage of fat mass with respect to controls. The endomorphy component was also significantly higher in women with PCOS than in controls. Each PCOS phenotype displayed a different representation in the somatochart respect to the others phenotypes and also compared to controls. Women with PCOS had significantly higher ∑7 SKF (p = 0.013), ∑appendicular SKF (p = 0.017) and ∑arm SKF (p = 0.019) than controls. H-O-POM phenotype had higher 7∑ SKF (p = 0.003), ∑appendicular SKF (p = 0.01), ∑arm SKF (0.005), ∑leg SKF, and ∑trunk SKF (0.008) and also a higher fast mass percentage than controls (p = 0.011). In conclusion, body composition evaluated by ISAK protocol is different in women with PCOS, especially in the complete phenotype (H-O-POM). This could have relevant implications in terms of clinical evaluation and follow-up of these women, although more researches in this field are needed.

BACKGROUND: Current evidence is insufficient to determine the contribution of stent grafts as treatment in partially thrombosed aneurysms or residual wall-adherent thrombi in arteriovenous fistulae (AVFs) for haemodialysis. The overall purpose of this study was to analyse patency rates of post-interventional covered stent deployment in those cases. We also assessed if patency rates differed when fistulas were punctured through the stent during dialysis sessions. METHODS: We conducted a retrospective study between 2006 and 2014 analysing post-intervention primary patency rates using the Kaplan-Meier log-rank test. Multivariate Cox proportional regression models were performed to determine if cannulation within the stent graft area was a potential risk factor for occlusion, by adjusted hazard ratio (HR). RESULTS: A total of 27 procedures were included in the study. Primary patency rates (%) after stent deployment at 3, 6, 12, 24, 36 and 72 months were, respectively: total 59, 32, 32, 21, 11 and 5; stent puncture 53, 21, 21, 16, 5 and 0; and no stent puncture 80, 80, 80, 40, 40 and 40. Cannulation through the stent graft was not significantly associated with increased risk of obstruction in multivariate analysis (HR = 3.01; P = 0.286). CONCLUSION: Stent graft treatment may be a feasible procedure in partially thrombosed aneurysms and residual thrombi in AVF. Although fistulas punctured through the stent presented lower patency rates, this practice was not associated with a higher risk of obstruction. Giving the impossibility of comparing with similar approaches, further studies are needed to confirm or refute the advantages of this procedure.

RESUMO

Polycystic ovary syndrome (PCOS) is a chronic endocrinopathy characterized by hyperandrogenism and anovulation that may pervade psychological dimensions such as dispositional optimism. Considering how PCOS influences mental health and the lack of studies on this matter, this research was aimed at assessing optimism and associated factors in PCOS. A case-control study of 156 patients with PCOS and 117 controls was conducted. All woman filled out the Life Orientation Test-Revised (LOT-R), a self-report questionnaire for measuring dispositional optimism. Medication, pain severity, gynecological, and sociodemographic information was also collected. Lower optimism was found in patients with PCOS compared to controls, even after covariate adjustment (LOT-R global scores: 14.1 vs. 15.9, p = 0.020). Our study provides evidence that a personality characteristic with important implications in illness prognosis may be affected in PCOS. We propose to assess dispositional optimism with the LOT-R scale in the gynecological appointment and tailor medical attention accordingly as a way to improve the comprehensive care of these patients within a multidisciplinary team.

RESUMO

Polycystic ovary syndrome (PCOS) is a complex hormonal disorder which impairs ovarian function. The adherence to healthy dietary patterns and physical exercise are the first line of recommended treatment for PCOS patients, but it is yet unclear what type of diet is more adequate. In this case-control study, we explored associations between adherence to five dietary quality indices and the presence of PCOS. We enrolled 126 cases of PCOS and 159 controls living in Murcia (Spain). Diagnostic of PCOS and its phenotypes were established following the Rotterdam criteria (hyperandrogenism (H), oligoanovulation (O), polycystic ovaries morphology (POM)). We used a validated food frequency questionnaires to calculate the scores of five dietary indices: alternate Healthy Eating index (AHEI), AHEI-2010, relative Mediterranean Dietary Score (rMED), alternate Mediterranean Dietary Score (aMED) and Dietary Approaches to Stop Hypertension (DASH). We used multivariable logistic regression to estimate adjusted odds ratios and confidence intervals. In the multivariable analysis, AHEI-2010 index was inversely associated with Hyperandrogenism + Oligoanovulation PCOS phenotype (ORQ3 vs. Q1 = 0.1; 95% CI: (0.0; 0.9); Pfor trend = 0.02). We did not find any statistical significant association between dietary indices and total anovulatory or ovulatory PCOS. However, further studies with higher sample sizes exploring these associations among the diverse phenotypes of PCOS are highly warranted.

RESUMO

INTRODUCTION: Endometriosis is a chronic painful condition characterized by high prognostic uncertainty, as well as the threat of infertility and emotional symptoms that may affect many aspects of women, including psychological characteristics like dispositional optimism. Considering the impact of endometriosis on psychological health and the paucity of papers on this topic, the aim of this study is to explore optimism and associated factors in endometriosis. METHODS: A case-control study was performed on a group of 95 women with endometriosis and 156 controls. All participants completed the Life Orientation Test-Revised (LOT-R), a self-administered tool for assessing dispositional optimism. Pain severity, medication, gynecological and socio-demographic information was also collected. RESULTS: Low optimism was observed for women with endometriosis compared to controls even after covariate adjustment (LOT-R global scores: 14.5 vs. 15.9 points, p = .045). CONCLUSIONS: This study provides the first evidence that a personality dimension with many prognostic implications may be altered in women with endometriosis. Our findings highlight the importance of a broader understanding of this condition, treating this disorder from a biopsychosocial perspective and suggests the need for non-medical attention within a multidisciplinary team.
