Evidence of high compliance and fatigue in mask adherence in two mandates in Barcelona, Spain: a naturalistic observational study.

OBJECTIVE: We investigated a possible pandemic fatigue effect, comparing adherence to compulsory mask use outdoors in Barcelona during the fourth and sixth waves of the pandemic. STUDY DESIGN: We used naturalistic observation to determine the degree of pedestrians' compliance. METHODS: We assessed mask use outdoors in a sample of pedestrians in Barcelona between 28 December 2021 and 9 February 2022 (during the sixth wave in Spain), and compared it with the fourth wave (which was between 5 April 2021 and 29 April 2021). Masks were compulsory in both periods. RESULTS: The population studied amounted to 45,116 people (21,246 in the fourth wave and 23,870 in the sixth wave). In the sixth wave, only 67.3% wore a mask correctly, 18.6% did so incorrectly and 14.1% did not wear a mask, while the figures for the fourth wave were 78.2%, 16.3% and 5.5%, respectively (P = 0.001). CONCLUSION: Our results suggest that adherence was high in the population studied, but with an evident fatigue effect when the two waves were compared, as the proportion of individuals wearing a mask correctly declined compared to the fourth wave. These results suggest that policymakers need guidance on adopting clear and enforceable guidelines during future mask mandates, assessing advantages and drawbacks in terms of the population's behavior to prevent the fatigue effect.

Enhanced recovery after surgery (ERAS®) society guidelines for gynecologic oncology: Addressing implementation challenges - 2023 update.

BACKGROUND: Despite evidence supporting its use, many Enhanced Recovery After Surgery (ERAS) recommendations remain poorly adhered to and barriers to ERAS implementation persist. In this second updated ERAS® Society guideline, a consensus for optimal perioperative care in gynecologic oncology surgery is presented, with a specific emphasis on implementation challenges. METHODS: Based on the gaps identified by clinician stakeholder groups, nine implementation challenge topics were prioritized for review. A database search of publications using Embase and PubMed was performed (2018-2023). Studies on each topic were selected with emphasis on meta-analyses, randomized controlled trials, and large prospective cohort studies. These studies were then reviewed and graded by an international panel according to the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. RESULTS: All recommendations on ERAS implementation challenge topics are based on best available evidence. The level of evidence for each item is presented accordingly. CONCLUSIONS: The updated evidence base and recommendations for stakeholder derived ERAS implementation challenges in gynecologic oncology are presented by the ERAS® Society in this consensus review.

Telemedicina, ética y derecho en tiempos de COVID-19. Una mirada hacia el futuro / Telemedicine, ethics, and law in times of COVID-19. A look towards the future

La emergencia sanitaria por COVID-19 en España fue de tal magnitud que el 14 de marzo de 2020 se declaró un estado de alarma que se mantuvo durante más de tres meses. Esta pandemia está afectando a un número muy elevado de personas. Para reducir su riesgo de contagio, entre las medidas tomadas se han minimizado las visitas a los centros sanitarios y se han incrementado las consultas telemáticas. Una vez se supere la situación de pandemia, cabrá plantearse si la práctica de la telemedicina queda limitada a situaciones de crisis sanitaria o puede convertirse en una nueva forma de practicar la medicina. La telemedicina carece de regulación específica y presenta lagunas que abocan al médico a considerables dosis de inseguridad. El presente artículo analiza los límites, las precauciones y los estándares legales del uso de la telemedicina (AU)

The health emergency in Spain caused by COVID-19 was of such a magnitude that on March 14, 2020, a state of alarm was declared that lasted for more than three months. This ongoing pandemic has affected a vast number of people. Among the measures taken to reduce the risk of contagion, visits to health centers have been reduced and virtual consultations have increased. Once the pandemic ends, it will be necessary to consider whether telemedicine should be limited to periods of health crises or whether it could become a new way of practicing medicine. Telemedicine lacks specific regulations and has loopholes that leave physicians with a considerable degree of insecurity. This article analyzes the limits, precautions, and legal standards of the use of telemedicine (AU)

Efecto de los fármacos modificadores del PH sobre los inhibidores de la tirosin quinasa: contrastando información / Effect of gastric-acid-reducing agents on the tyrosine kinasa inhibitors: contrasting information

Objetivos: Los inhibidores de la tirosin quinasa (ITK) comprenden un conjunto de moléculas ampliamente utilizadas actualmente en onco-hematología. Los ITK han supuesto una ventaja para los pacientes, de forma que la administración oral favorece su autonomía, pero a su vez, su absorción gastrointestinal y, por ende, su biodisponibilidad, puede verse alterada por el PH-gástrico. Las interacciones con los fármacos modificadores del PH son un problema conocido y una consulta frecuente. El objetivo del estudio fue analizar las interacciones ITK-fármacos modificadores del PH-gástrico y las discrepancias en diferentes bases de datos. Con los resultados, se elaboró una tabla, para proporcionar a los pacientes la información correcta y consensuada, y no generar así inseguridad que comprometa la adherencia al tratamiento o confianza hacia el profesional sanitario. Métodos: Se exportaron de la web de la Agencia Española del Medicamento y Productos Sanitarios los fármacos clasificados como ITK directos (ATC: L01XE). Se consultó la interacción de éstos con los IBP, Anti-H2 y antiácidos en diversas fuentes y se resumieron los hallazgos.Resultados y conclusiones: Para establecer una fuerte recomendación, es necesario consultar varias bases de datos, ya que las discrepancias o la información insuficiente pueden llevar a recomendaciones erróneas. Es importante establecer un consenso entre profesionales para realizar la recomendación correcta, y no ver comprometida la eficacia del tratamiento, con las importantes consecuencias que ello conllevaría. (AU)

Objectives: Tyrosine kinase inhibitors (TKIs) include a group of molecules widely used in oncohematology today. Using the oral administration route of TKIs offers an advantage for the patient; favoring patient autonomy, however, oral administration also causes relevant new problems. Gastrointestinal absorption and, therefore, bioavailability, can be altered by gastric PH. Interactions of these TKIs with gastric acid reducing (GAR) drugs are a known problem and a frequent query in clinical practice. The aim was to analyze ITK-GAR drugs interactions and discrepancies in different databases. Based on the results, a table was elaborated to provide the correct and consensed information, and thus not generate insecurity that compromises the adherence to the treatment or trust towards the healthcare professional.Methods: Drugs classified as direct ITKs (ATC: L01XE) were exported from the Spanish Agency for Medicines and Health Products website. Their interaction with PPIs, Anti-H2 and antacids was consulted in different databases and findings were summarized.Results and conclusions: To establish a strong recommendation, it is necessary to consult several databases, because of discrepancies or insufficient information can lead to erroneous recommendations. It is important to establish a consensus among professionals to make the correct recommendation, and not compromising the effectiveness of the treatment, which would entail important consequences.

Monitorización farmacocinética de terapias biológicas en enfermedad inflamatoria intestinal / Pharmacokinetic monitoring of biological therapies in inflammatory bowel disease

Objective: To analyze the activity developed by a multidisciplinary team of pharmacists, digestive specialists and clinical analysts for the therapeutic drug monitoring (TDM) of anti-TNFa therapies in inflammatory bowel disease (IBD).Methods: A prospective observational study (January-December 2019) was conducted of referrals from digestive specialists to the Clinical Pharmacokinetics Unit (CPU) of our general hospital for the TDM of anti-TNFa drugs (infliximab/adalimumab) in adults with IBD. Serum anti-TNFa concentrations were quantified in our Clinical Analysis Laboratory using lateral flow chromatography. When concentrations were undetectable, the presence of anti-drug antibodies (ADAs) was analyzed.CPU recommendations were based on the correct interpretation of anti-TNFa concentrations, therapeutic algorithms, and populational pharmacokinetic models implemented using MW-Pharm++® software. Results: Referrals were received for 84 patients (81.0% with Crohn’s disease, 8.3% with ADAs) treated with infliximab (46.4%) or adalimumab (53.6%); 64.3% were also treated with concomitant immunomodulators (IMMs). Sixty-three referrals (75.0%) were for proactive monitoring (treatment optimization) and the remainder for reactive monitoring after therapeutic failure. Anti-TNFa concentrations were subtherapeutic in 36.9% of patients, therapeutic in 39.3%, and supratherapeutic in 23.8%. Subtherapeutic/undetectable concentrations were significantly more frequent (p≤0.004) in patients treated with infliximab versus adalimumab (64.1% vs.. 13.3%) and in concomitant IMM non-adherents versus adherents (85.7% vs. 25.5%). Conclusions: Anti-TNFa TDM is frequently proactive in patients with IBD. The wide variability in anti-TNFa concentrations is in part explained by the type of anti-TNFa drug and adherence to IMM.

Objetivo: Analizar la actividad desarrollada por un equipo multidisciplinar formado por farmacéuticos, digestólogos y analistas clínicos para la monitorización farmacocinética (TDM) de terapias anti-TNFa en la enfermedad inflamatoria intestinal (EII).Métodos: Estudio observacional prospectivo (enero–diciembre 2019) de las interconsultas de TDM de anti-TNFa (infliximab/adalimumab) en pacientes adultos con EII, solicitadas por digestólogos a la Unidad de Farmacocinética Clínica (UFC) del Servicio de Farmacia de un hospital general. Las concentraciones séricas (Cs) de anti-TNFa fueron cuantificadas en el Laboratorio de Análisis Clínicos mediante cromatografía de flujo lateral. Cuando las Cs fueron indetectables, se analizó la presencia de anticuerpos anti-fármaco (AAF).La UFC realizó recomendaciones en base a la correcta interpretación de las Cs de anti-TNFa, algoritmos terapéuticos y modelos farmacocinéticos poblacionales implementados en el programa informático de ajuste bayesiano MW-Pharm++®. Resultados: Se solicitaron interconsultas para 84 pacientes (81,0% enfermedad de Crohn, 8,3% AAF positivos) con infliximab (46,4%) ó adalimumab (53,6%). 64,3% recibía otros inmunomoduladores (IMM) concomitantes. 63 interconsultas (75,0%) se relacionaron con monitorización ‘pro-activa’ (optimizar tratamiento); el resto fueron ‘re-activas’ a fallo terapéutico. Se observaron Cs de anti-TNFa subterapéuticas en 36,9% de pacientes, terapéuticas en 39,3% y supraterapéuticas en 23,8%. Las Cs subterapéuticas/indetectables fueron significativamente (p≤0,004) más frecuentes en pacientes tratados con infliximab versus adalimumab (64,1% vs. 13,3%); y en ‘no-adherentes’ versus ‘sí-adherentes’ al IMM concomitante (85,7% vs. 25,5%). Conclusiones: En estos pacientes, la TDM de anti-TNFa es frecuentemente ‘pro-activa’. Existe gran variabilidad en las Cs de anti-TNFa, explicada en parte por el fármaco anti-TNFa y la adherencia al IMM. (AU)

Measurements of adiposity as prognostic biomarkers for survival with anti-angiogenic treatment in epithelial ovarian cancer: An NRG Oncology/Gynecologic Oncology Group ancillary data analysis of GOG 218.

OBJECTIVE: Adiposity has been hypothesized to interfere with the activity of bevacizumab (BEV), an anti-angiogenic agent. Measurements of adiposity, BMI, surface fat area (SFA), and visceral fat area (VFA) were investigated as prognostic of oncologic outcomes among patients treated with chemotherapy, with or without BEV, on GOG 218, a prospective phase III trial. METHOD: Pretreatment computed tomography (CT) for 1538 GOG 218 participants were analyzed. Proportional hazards models assessed association between adiposity and overall survival (OS) adjusted for other prognostic factors. The predictive value of adiposity as a function of BEV treatment was assessed in 1019 patients randomized to either chemotherapy (CT) + placebo (P) → P or CT + BEV → BEV. RESULTS: After adjusting for prognostic factors, SFA was not associated with the overall hazard of death (p = 0.981). There was a non-significant 0.1% (p = 0.062) increase in hazard of death associated with a unit increase in VFA. When comparing the treatment HRs for patients who did and did not receive BEV, there was no association with SFA (p = 0.890) or VFA (p = 0.106). A non-significant 0.8% increase in the hazard of death with unit increase in BMI (p = 0.086) was observed. BMI values were not predictive of a longer survival for patients with BEV vs placebo (p = 0.606). CONCLUSION: Measures of adiposity strongly correlated to one another but were not predictive of efficacy for BEV. VFA is a weak prognostic factor.

The antigenic variability of HCV in viral HLA-Ag binding is related to the activation of the host immune response.

Our previous data show that hepatitis C virus (HCV) genotype 1 patients expressing the HLA-DQB1 * 0301 allele have a combined response probability of 69%, while the remaining 31% do not respond, probably because the HCV immunodominant epitope (IE) against the DQB1 * 0301 allele is mutated. HCV IE (region sequenced in NS3 is a region encoding aa 1253-1272) from 37 patients (21 Sustained Virological Response, SVR; 16 non-SVR) HLA-DQB1 * 0301+, were analysed by pyrosequencing. In vitro cultures were also determined by CD4+ proliferation, using non-mutated IE (wild-type synthetic peptide) and synthetic mutated peptide. The pyrosequencing study revealed 34 different haplotypes. The SVR patients had fewer haplotypes (P = 0.07), mutations/haplotypes (P = 0.01) and polymorphic sites (P = 0.02) than non-SVR. Three polymorphic sites were associated with the non-SVR patients: haplotype 7 (L5P); haplotype 11 (L7P); and haplotype 15, (L15S) (P = 0.02). The in vitro study (n = 7) showed that in 4/7 patients (Group 1) the CD4+ proliferation obtained with wild-type synthetic peptide was higher than that obtained with the negative control and with the synthetic mutated peptide (P = 0.039). However, in the remaining 3/7 patients (Group 2) this pattern was not observed (P = 0.7). Our findings suggest that HLA-DQB1 * 0301+ patients with high antigenic variability in HCV IE (NS31253-1272) have a lower SVR rate, due to reduced CD4+ proliferation as a result of incorrect viral HLA-Ag binding.

Vaginal vs. robotic hysterectomy for patients with endometrial cancer: A comparison of outcomes and cost of care.

OBJECTIVE: To compare outcomes and cost for patients with endometrial cancer undergoing vaginal hysterectomy (VH) or robotic hysterectomy (RH), with or without lymphadenectomy (LND). METHODS: Patients undergoing planned VH (and laparoscopic LND) or RH (and robotic LND) between January 2007 and November 2012 were reviewed. Patients with stage IV disease, synchronous cancer, synchronous surgery, or treated with palliative intent were excluded. Patients were objectively triaged to LND per institutional protocol based on frozen section. Outcomes were compared between VH and RH groups matched 1:1 on propensity scores. RESULTS: VH was planned in 153 patients; 60 (39%) had concurrent LND while 93 (61%) were low risk and did not require LND. RH was planned in 398 patients; 225 (56%) required concurrent LND and 173 (44%) did not. Among 50 PS-matched pairs without LND, there was no significant difference in complications, length of stay, readmission, or progression free survival. However, median operative time was 1.3h longer and median 30-day cost $3150 higher for RH compared to VH (both p<0.001). Among patients requiring LND, 42 PS-matched pairs were identified. Median operative time was not different when pelvic and para-aortic LND was performed, and 12min longer in the VH group for pelvic LND alone (p=0.03). Median 30-day cost was $921 higher for RH compared to VH when LND was required (p=0.08). CONCLUSION: Utilization of vaginal hysterectomy for endometrial cancer results in similar surgical and oncologic outcomes and lower costs compared to RH and should be considered for appropriate patients with a low risk of requiring LND.

Influence of HLA class I, HLA class II and KIRs on vertical transmission and chronicity of hepatitis C virus in children.

BACKGROUND & AIM: There is evidence that maternal viral load of HCV during delivery influences the risk for Mother-to-child transmission (MTCT), but this does not explain all cases. We study the role of the immunogenetic profile (HLA, KIRs and KIR-ligand binding) of mothers and children in HCV-MTCT and in chronicity in the children. METHODOLOGY: 79 HCV-RNA (+) mothers and their 98 children were included. 24 children were infected, becoming chronic in 8 cases and clearing in 16. HLA-class-I and II and KIRs were determined by Luminex. RESULTS: MTCT study: The presence of HLA-C1-ligand in mothers and/or their children reduces the risk of transmission (mothers: Pc = 0.011, children: P = 0.033), whereas the presence of HLA-C2C2-ligand in mothers increases it (Pc = 0.011). In children KIR2DL3-HLA-C1 is a protector factor (Pc = 0.011). Chronicity in children study: Maternal DQA1*01 allele (Pc = 0.027), KIR2DS1 (Pc = 0.011) or KIR3DS1 (Pc = 0.011) favours chronicity in the child. The presence of the DQB1*03 allele (Pc = 0.027) and KIR2DS3 (P = 0.056) in the child and homozygosity for KIR3DL1/3DL1 (Pc = 0.011) and for the HLA-Bw4/Bw4 ligand (P = 0.027) is associated with viral clearance, whereas the presence of HLA-Bw6 ligand (P = 0.027), the binding of KIR3DS1-HLA-Bw4 (P = 0.037) and heterozygosity for KIR3DL1/3DS1 (Pc = 0.011) favour viral chronicity. Mother/child allele matching: In the joint HLA analysis, matching was greater between mothers and children with chronic infection vs those who had cleared the virus (67%±4.1 vs 57%±1.2, P = 0.003). CONCLUSIONS: The HLA-C1 ligand in the mother is related to MTCT, while several genetic factors of the mother or child are involved in the chronification or clearance of infection in the child. Matching allelic data is considered to be an indicator of HCV chronicity in the child and can be used as a potential prognostic test. This implies that NK cells may play a previously undocumented role in protecting against MTCT and that both NK cell immunity and adaptive T-cell responses may influence viral clearance in infected children.

Virulence and genotypes of white spot syndrome virus infecting Pacific white shrimp Litopenaeus vannamei in north-western Mexico.

White spot syndrome virus (WSSV) has caused substantial global economic impact on aquaculture, and it has been determined that strains can vary in virulence. In this study, the effect of viral load was evaluated by infecting Litopenaeus vannamei with 10-fold serial dilution of tissue infected with strain WSSV Mx-H, and the virulence of four WSSV strains from north-western Mexico was assessed along with their variable number of tandem repeat (VNTR) genotypes in ORF75, ORF94 and ORF125. The LD50 of the Mx-H strain was a dilution dose of 10-7.5 ; the mortality titre was 109.2 LD50 per gram. In shrimp injected with 102.5 to 106.5 LD50 , no significant virulence differences were evident. Using mortality data, the four WSSV strains grouped into three virulence levels. The Mx-F strain (intermediate virulence) and the Mx-C strain (high virulence) showed more genetic differences than those observed between the Mx-G (low-virulence) and Mx-H (high-virulence) strains, in ORF94 and ORF125. The application of high-viral-load inocula proved useful in determining the different virulence phenotypes of the WSSV strains from the Eastern Pacific.

Litio para el tratamiento de la esclerosis lateral amiotrófica: mucho ruido para nada / Lithium for treatment of amyotrophic lateral sclerosis: much ado about nothing

Introducción: El litio fue propuesto en 2008 como un candidato eficaz en el tratamiento de ELA tras reportarse que era capaz de retrasar el deterioro funcional en un 40% y que ninguno de los 16 pacientes tratados con una combinación de litio más riluzole falleció durante un periodo de seguimiento de 15 meses. Los excelentes resultados de este estudio piloto despertaron una gran expectativa en pacientes, familiares, asociaciones de enfermos y comunidad científica. Consecuencia directa de esta noticia fue la puesta en marcha de numerosos ensayos clínicos en fase ii. Muchos de los pacientes, que no pudieron ser incluidos en estos estudios, utilizaron todos sus recursos para acceder a este fármaco mediante uso compasivo. Objetivos: Evaluar la eficacia del litio en ELA mediante un metaanálisis de la información reportada en 12 de estos estudios. Se analiza su calidad metodológica. Material y métodos: Se realizaron búsquedas en MEDLINE, EMBASE y Registros Cochrane del Grupo de Enfermedades Neuromusculares, ClinicalTrials.gov y EudraCT (enero de 1996-agosto de 2012). Resultados: Hasta la fecha disponemos de información de más de 1.100 pacientes tratados con litio. Lamentablemente los resultados obtenidos no confirman el efecto positivo descrito en el estudio piloto y sugieren que este fármaco es ineficaz para detener la progresión de la enfermedad. Dos ensayos tuvieron que ser suspendidos antes del plazo previsto por ineficacia del fármaco y por numerosos efectos adversos. En un estudio publicado recientemente se descarta también cualquier posibilidad de un mínimo efecto. Conclusiones: Hay evidencia de que el litio no ofrece beneficios a corto plazo en ELA. Al comparar el grupo de pacientes tratados con litio + riluzole con el grupo control tratado con riluzole no se observan diferencias estadísticamente significativas en las tasas de deterioro funcional o de deterioro de la función respiratoria ni tampoco en la supervivencia. No hay tampoco evidencia de que sea superior al placebo

Introduction: Lithium was proposed in 2008 as an effective candidate in the treatment of ALS after a report claimed that it was able to delay functional deterioration by 40% and that none of the 16 patients treated with a combination of lithium plus riluzole had died during a 15-month follow-up period. The excellent results of this pilot study engendered considerable optimism among patients, their families, patients’ associations, and the scientific community. This report sparked numerous phase ii clinical trials. Many patients who were not included in these studies used all resources at their disposal to access the drug as treatment under a compassionate use programme. Objectives: To evaluate the effectiveness of lithium in ALS using a meta-analysis of the information reported in 12 studies which were examined for methodological quality. Material and methods: Searches were performed using MEDLINE, EMBASE, the Cochrane Neuromuscular Disease Group Trials Register, ClinicalTrials.gov, and EudraCT (January 1996-August 2012). Results: To date, we have information on more 1100 patients treated with lithium. Unfortunately, the results do not confirm the positive effect described in the pilot study, which suggests that this drug is not effective at slowing disease progression. Two trials had to be suspended before the scheduled completion date due to the ineffectiveness of the drug as well as numerous adverse effects. A recently published study also ruled out any possible modest effect. Conclusions: There is evidence to suggest that lithium has no short-term benefits in ALS. A comparison of the group of patients treated with lithium + riluzole and the control group treated with riluzole alone showed no statistically significant differences in rates of functional decline, deterioration of respiratory function, or survival time. Furthermore, there was no evidence that it was more effective than the placebo

The clinical profile of women with stable ischaemic heart disease in Spain. More effort is needed in secondary prevention. SIRENA study.

OBJECTIVES: Cardiovascular diseases are the leading cause of death for women, especially ischaemic heart disease, which is still considered a man's disease. In Spain, there are various registries on ischaemic heart disease, although none are exclusively for women. The objectives of the SIRENA study were to describe the clinical profile of women with ischaemic heart disease treated in cardiology consultations, to estimate its prevalence of cardiovascular risk factors and understand its clinical management. PATIENTS AND METHODS: A multicentre observational study was conducted with a sample of 631 women with stable ischaemic heart disease, consecutively included during cardiology consultations. Forty-one researchers from all over Spain participated in the study. RESULTS: The mean age was 68.5 years. The clinical presentation was in the form of acute coronary syndrome in up to 67.2% of the patients. The prevalence of cardiovascular risk factors was high (77.7% of the patients had hypertension, 40.7% had diabetes and 68% had dyslipidaemia), with 30.7% having uncontrolled hypertension, 78.4% having LDL-cholesterol levels higher than 70mg/dL and 49.2% having HbA1c levels greater than 7%. The considerable majority of the patients underwent optimal medical treatment with antiplatelet agents, beta-blockers, renin-angiotensin-aldosterone system blockers and hypolipidaemic agents. Coronary angiography was performed for 88.3% of the patients, and 63.4% underwent percutaneous coronary intervention. CONCLUSIONS: Women with stable ischaemic heart disease in Spain initially present some form of acute coronary syndrome and a high prevalence of inadequately controlled cardiovascular risk factors, despite undergoing optimal medical therapy. A high percentage of these women undergo coronary revascularisation. Increased efforts are required for secondary prevention in women with stable ischaemic heart disease.

Exposure to a low dose of bisphenol A impairs pituitary-ovarian axis in prepubertal rats: effects on early folliculogenesis.

The research work studies the effect of providing a low dose of bisphenol A (BPA), on the reproductive axis of prepubertal female rats. Wistar mated rats were treated with either 0.1% ethanol or BPA in their drinking water until their offspring were weaned on the 21 day of birth. The estimated average dose of exposure to dams was approximately 3µg/kg/day. The pups were sacrificed at the 30th day of life. Body weight at the moment of the sacrifice was significantly higher in the group exposed to BPA; ovarian weight and its relative weight were not modified. LH and estradiol levels increased significantly, meanwhile FSH ones showed no significant changes. The number of primary, secondary and atretic follicles increased and antral ones was decreased. Our results demonstrated that early exposure to a low dose of BPA disrupts the normal function of the reproductive axis in prepubertal female rats.
