RESUMEN

AIM: To assess the birthweight of neonates conceived after fresh and frozen embryo transfers (FET) and, if different, to investigate whether estradiol levels during the late follicular phase were associated with the observed difference. METHODS: Singleton pregnancies from fresh and FET transfers between January 1990 and December 2013 were compared retrospectively. A total of 2885 singleton pregnancies after fresh embryo transfer and 746 after FET were analyzed. Obstetric and neonatal outcomes were compared between fresh and FET cycles. RESULTS: The singletons born after FET were found to have a significantly higher birth weight (3313 g), compared to those born after fresh embryo transfer (3143 g); p < .001. The main predictor of this difference was found to be estradiol levels at the end of the follicular phase. The difference in birthweight was inversely correlated to estradiol levels considering all cycles together but also considering fresh and frozen cycles separately. CONCLUSIONS: Our study demonstrates a link between high estradiol levels and low birth weight of singletons after IVF both in fresh and frozen-thawed embryo transfer cycles. It provides additional support to the involvement of hyperestrogenemia in the process of implantation and on the subsequent fetal development.

RESUMEN

OBJECTIVES: Our aim was to compare maternal and neonatal outcomes of women with a low-risk pregnancy attending the "Cocoon," an alongside midwifery-led birth center and care pathway, with women with a low-risk pregnancy attending the traditional care pathway in a tertiary care hospital in Belgium. METHODS: We performed a retrospective cohort study of maternal and neonatal outcomes of women with a low-risk pregnancy who chose to adhere to the Cocoon pathway of care (n = 590) and women with a low-risk pregnancy who chose the traditional pathway of care (n = 394) from March 1, 2014, to February 29, 2016. We performed all analyses using an intention-to-treat approach. RESULTS: In this setting, the cesarean birth rate was 10.3% compared with 16.0% in the traditional care pathway (adjusted odds ratios [aOR] 0.42 [95% CI 0.25-0.69]), the induction rate was 16.3% compared with 30.5% (0.46 [0.30-0.69]), the epidural analgesia rate was 24.9% compared with 59.1% (0.15 [0.09-0.22]), and the episiotomy rate was 6.8% compared with 14.5% (0.31 [0.17-0.56]). There was no increase in adverse neonatal outcomes. Intrapartum and postpartum transfer rates to the traditional pathway of care were 21.1% and 7.1%, respectively. CONCLUSIONS: Women planning their births in the midwifery-led unit, the Cocoon, experienced fewer interventions with no increase in adverse neonatal outcomes. Our study gives initial support for the introduction of similar midwifery-led care pathways in other hospitals in Belgium.

RESUMEN

The aim of this study was to evaluate whether pregnancies resulting from oocyte donation have a higher risk of preeclampsia compared with pregnancies after IVF using autologous oocytes. Propensity score matching on maternal age and parity was carried out on a one to one basis, and a total of 144 singleton pregnancies resulting in delivery beyond 22 gestational weeks, achieved by oocyte donation, were compared with 144 pregnancies achieved through IVF and intracytoplasmic sperm injection with the use of autologous oocytes. All pregnancies were achieved after fresh embryo transfer. Obstetric and neonatal outcomes were compared for each pregnancy. Singleton pregnancies after oocyte donation were associated with a significantly higher risk for preeclampsia (OR 2.4, CI 1.02 to 5.8; P = 0.046), as well as for pregnancy-induced hypertension (OR 5.3, CI 1.1 to 25.2; P = 0.036), and caesarean delivery (OR 2.3, CI 1.4 to 3.7; P = 0.001) compared with pregnancies using autologous oocytes.

RESUMEN

PURPOSE: The purpose of the present study is to study what is the best predictor of severe ovarian hyperstimulation syndrome (OHSS) in IVF. METHODS: This is a retrospective analysis of all consecutive IVF/intracytoplasmic injection cycles performed during a 5-year period (2009-2014) in a single university fertility centre. All fresh IVF cycles where ovarian stimulation was performed with gonadotrophins and GnRH agonists or antagonists and triggering of final oocyte maturation was induced with the administration of urinary or recombinant hCG were analyzed (2982 patients undergoing 5493 cycles). Because some patients contributed more than one cycle, the analysis of the data was performed with the use of generalized estimating equation (GEE). RESULTS: Severe OHSS was diagnosed in 20 cycles (0.36%, 95% CI 0.20-0.52). The number of follicles ≥10 mm on the day of triggering final oocyte maturation represents the best predictor of severe OHSS in IVF cycles. The cutoff in the number of follicles ≥10 mm with the best capacity to discriminate between women that will and will not develop severe OHSS was ≥15. CONCLUSION: The presence of more than 15 follicles ≥10 mm on the day of triggering final oocyte maturation represents the best predictor of severe OHSS in IVF cycles.

RESUMEN

PURPOSE: To compare two different vitrification methods to slow freezing method for cryopreservation of human cleavage stage embryos. DESIGN: Prospective randomised trial. SETTING: University assisted reproduction centre. PATIENT(S): 568 patients (mean age 33.4 ± 5.2) from April 2009 to April 2011. METHODS: 1798 supernumerary good-quality cleavage stage embryos in 645 IVF cycles intended to be cryopreserved were randomly allocated to three groups: slow freezing, vitrification with the Irvine® method, vitrification with the Vitrolife® method. MAIN OUTCOME MEASURE(S): Embryo survival and cleavage rates, implantation rate. RESULTS: A total of 1055 embryos were warmed, 836 (79.2%) survived and 676 were finally transferred (64.1%). Post-warming embryos survival rate was significantly higher after vitrification (Irvine: 89.4%; Vitrolife: 87.6%) than after slow freezing (63.8%) (p < 0.001). No differences in survival rates were observed between the two vitrification methods, but a significant higher cleavage rate was observed using Irvine compared to Vitrolife method (p < 0.05). Implantation rate (IR) per embryo replaced and per embryo warmed were respectively 15.8% (41/259) and 12.4% (41/330) for Irvine, 17.0% (40/235) and 12.1% (40/330) for Vitrolife, 21.4% (39/182) and 9.9% (39/395) for slow-freezing (NS). CONCLUSIONS: Both vitrification methods (Irvine and Vitrolife) are more efficient than slow freezing for cryopreservation of human cleavage stage embryos in terms of post-warming survival rate. No significant difference in the implantation rate was observed between the three cryopreservation methods.

RESUMEN

BACKGROUND: If it is well known that obesity increases morbidity for both mother and fetus and is associated with a variety of adverse reproductive outcomes, then few studies have assessed the relation between obesity and neonatal outcomes. This is the aim of the present study after taking into account type of labor and delivery, as well as social, medical and hospital characteristics in a population-based analysis. METHODS: This study used 2009 data from the Belgian birth register data pertaining to the regions of Brussels and Wallonia and included 38,675 consecutive births. Odds ratio and 95% confidence intervals for admission to neonatal intensive care unit, Apgar score, and perinatal mortality were calculated by logistic regression analyses adjusting for medical, social and hospital characteristics using obesity as the primary independent variable. The impact of analyzing all delivery sites together was tested using mixed-effect analyses. RESULTS: The adjusted odds ratio for neonatal intensive care unit admission was higher for obese mothers by 38% compared to non-obese mothers (95% confidence interval (CI): 1.22-1.56), and by 45% (CI: 1.21-1.73) and 34% (CI: 1.10-1.63) after spontaneous and induced labour respectively. The adjusted odds ratio was 1.18 (CI: 0.86-1.63) after caesarean section. The adjusted odds ratio for 1 minute Apgar score inferior to 7 was higher for obese mothers by 31% compared to non-obese mothers (CI: 1.15-1.49) and by 26% (CI: 1.04-1.52) and 38% (CI: 1.12-1.69) after spontaneous and induced labour respectively. The adjusted odds ratio was 1.50 (CI: 0.96-2.36) after caesarean section. The adjusted odds ratio for perinatal mortality was 1.36 (CI: 0.75-2.45) for obese mothers compared to non-obese mothers. CONCLUSIONS: Neonatal admission to intensive care and low Apgar scores were more likely to occur in infants from obese mothers, both after spontaneous and induced labor.

RESUMEN

OBJECTIVE: To provide insight into the differential effect of immigration on cesarean section (CS) rates, using the Robson classification. DESIGN: A population-based study using birth certificates from the birth registry of 2009. SETTING: All births in two of the three Belgian regions excluding Flanders. POPULATION: 37 628 deliveries from Belgian and immigrant mothers from sub-Saharan Africa, Maghreb and Eastern Europe. METHODS: Multivariate analyses using CS as the dependent variable and immigration status as the primary independent variable. Several multivariate logistic regression models were built including medical, anthropometric, socio-economic characteristics, and medical interventions. The impact of analyzing all delivery sites together was tested using mixed-effect analyses. MAIN OUTCOME MEASURES: CSs of immigrant subgroups compared with Belgian women. RESULTS: CS rates varied according to immigrant subgroups. Mothers from sub-Saharan Africa had an adjusted odds ratio of 2.06 (1.62-2.63) for CS compared with Belgian natives. Increased risk for mothers from sub-Saharan Africa compared with Belgian natives was found among nulliparous and multiparous women without previous CS, and a term, singleton fetus in cephalic position. In comparison, nulliparous East European mothers with a term singleton fetus in cephalic position in spontaneous labor had an adjusted odds ratio of 0.29 (0.08-0.99) for CS. CONCLUSIONS: CS rates currently vary between Robson categories in immigrant subgroups. Immigrant mothers from sub-Saharan Africa with a term, singleton infant in cephalic position, without previous CS, appear to carry the highest burden.

RESUMEN

BACKGROUND: Differences in neonatal mortality among immigrants have been documented in Belgium and elsewhere, and these disparities are poorly understood. Our objective was to compare perinatal mortality rates in immigrant mothers according to citizenship status. METHODS: This was a population-based study using 2008 data from the Belgian birth register data pertaining to regions of Brussels and Wallonia. Odds ratio (OR) and 95% confidence intervals (95% CIs) for perinatal mortality according to naturalization status were calculated by logistic regression analyses adjusting for parents' medical and social characteristics. RESULTS: Four hundred and thirty-seven perinatal deaths were registered among 60,881 births (7.2‰). Perinatal mortality rate varied according to the origin of the mother and her naturalization status: among immigrants, non-naturalized immigrants had a higher incidence of perinatal mortality (10.3‰) than their naturalized counterparts (6.1‰) with an adjusted OR of 2.2, 95% CI (1.1-4.5). CONCLUSION: In a country with a high frequency of naturalization, and universal access to health care, naturalized immigrant mothers experience less perinatal mortality than their not naturalized counterparts.

RESUMEN

PURPOSE: This study aims to determine if in-vitro maturation (IVM) of human immature oocytes should be performed before or after vitrification. METHODS: A total of 184 immature oocytes were randomly divided into two different groups: 100 were vitrified at metaphase II (MII) stage 24 h-48 h after IVM (group 1) and 84 were immediately vitrified at germinal vesicle (GV) or metaphase I (MI) stages and in vitro matured after warming (group 2). RESULTS: Survival rate after warming was similar in both groups (86.9% versus 84.5%). However, oocyte maturation rate per collected oocyte was significantly higher for oocytes matured before vitrification (group 1, 46%) than for oocytes vitrified before IVM (group 2, 23.8%) (p < 0.01). Consequently, the number of MII oocytes inseminated per oocyte collected was significantly higher for group 1 (40%) than for group 2 (23.8%) (p < 0.05). CONCLUSION: IVM procedure is more efficient when it is performed before oocyte vitrification.

RESUMEN

Human papillomavirus (HPV) is an epitheliotropic virus typically infecting keratinocytes but also possibly epithelial trophoblastic placental cells. In the present study, we set out to investigate whether HPV can be recovered from transabdominally obtained placental cells to avoid any confounding contamination by HPV-infected cervical cells. Thirty-five placental samples from women undergoing transabdominal chorionic villous sampling were analyzed, and we detected HPV-16 and HPV-62 in 2 placentas. This study suggests that HPV infection of the placenta can occur early in pregnancy. The overall clinical implication of these results remains to be elucidated.

RESUMEN

INTRODUCTION: A caesarean section is a major obstetric procedure that can save the life of mother and child. Its purpose is to protect the mother's health from the complications of childbirth and to protect the baby's health. In sub-Saharan Africa (SSA), there are major inequalities in access to caesarean sections and significant variations in practices to determine the indications for the procedure. Periodic analyses of maternal deaths have shown that more than half of maternal and new born deaths are due to suboptimal care and are therefore potentially preventable. The objective of our study is to assess the impact of health staff training under the PADISS project (to support the health system's integrated development) on the quality of CS procedures in North Kivu, by comparing two periods. MATERIAL AND METHODS: The populations compared were recruited from the referral hospitals in North Kivu, DRC (Democratic Republic of Congo). The first (group 1) was made up of patient files studied retrospectively for the period from 01/11/2013 to 01/01/2016. The second group (group 2), studied prospectively, comprised patient files from June 2019 to January 2020. Obstetric, maternal and foetal data were compared. Statistical analyses were performed using STATA/IC 15.0 for Windows. Univariate and multiple logistic regression was performed to determine which characteristics are associated with maternal and perinatal morbidity and mortality. A p value < 0.05 was considered statistically significant. RESULTS: CS frequency was approximately 17% in both study periods. We observed a CS frequency of about 34% at North Kivu provincial hospital for the two populations studied. The main indications for CS were dystocia, foetal distress and scarred uterus for both populations. In the population studied prospectively, after the implementation of health staff training, there were fewer incidence rate of dystocia, foetal distress and neonatal death, a more complete patient record, shorter hospital stay, and fewer blood transfusions but more incidence rate of scarred uterus, post-operative complications and low birth weight. Intervention had no statistically significant impact on low birth weight (OR = 1.9, p = 0.13), on neonatal mortality (OR = 0.69, p = 0.21). CONCLUSION: Our study shows a decrease in neonatal deaths, dystocia and foetal distress, but an increase in post-operative complications, maternal deaths and cases of scarred uterus and low birth weight. However, multiple logistic regression did no support the conclusion.

RESUMEN

Aggressive chemotherapy generally results in the loss of both endocrine and reproductive functions. If the patient has not undergone previous oocyte, embryo or ovarian tissue cryopreservation, orthotopic allotransplantation of fresh ovarian tissue from a genetically non-identical sister may be considered. Here, we describe a case report. The patient, aged 15 years and presenting with homozygous sickle cell anemia, underwent chemotherapy (busulfan, cyclophosphamide) and total body irradiation before bone marrow transplantation, the donor being her HLA-compatible sister. HLA group analysis later revealed complete chimerism. When the patient was 32 years old, ovarian allografting was performed, with the ovarian tissue donor being the same sister who had already donated bone marrow. The goal was to restore ovarian activity and natural fertility. No immunosuppressive therapy was administered. No sign of rejection was observed. Restoration of ovarian function was achieved 3.5 months after transplantation, as proved by the first estradiol peak and follicular development detected by ultrasound. After 9 months of regular ovulatory cycles, IVF was attempted because proximal tubal stenosis (unknown at the time of grafting) could not be repaired by tubal reanastomosis. After stimulation, three oocytes were retrieved. Two embryos were obtained. One embryo was frozen and the other was transferred, resulting in an ongoing pregnancy. The patient delivered a healthy baby girl weighing 3.150 g at 37 2/7 weeks of gestation.

RESUMEN

BACKGROUND: In the past few years, cryopreservation of ovarian tissue has become an established procedure proposed in many centers around the world and transplantation has successfully resulted in full-term pregnancies and deliveries in human. This prospective study aims to evaluate the feasibility of vitrifying in vitro matured oocytes (IVM) isolated at the time of ovarian tissue cryopreservation to improve the efficiency of fertility preservation programs. METHODS: Oocyte-cumulus complexes were retrieved from freshly collected ovarian cortex by aspirating antral follicular fluid, and were matured in vitro for 24-48 h prior to vitrification. Oocytes were matured in an IVM commercial medium (Copper Surgical, USA) supplemented with 75 mIU/ml FSH and 75 mIU/ml LH and vitrified using a commercial vitrification kit (Irvine Scientific, California) in high security vitrification straws (CryoBioSystem, France). Oocyte collection and IVM rates were evaluated according to the age, the cycle period and the amount of tissue collected. RESULTS: Immature oocyte retrieval from ovarian tissue was carried out in 57 patients between 8 and 35 years of age, undergoing ovarian tissue cryopreservation. A total of 266 oocytes were isolated, 28 of them were degenerated, 200 were at germinal vesicle stage (GV), 35 were in metaphase I (MI) and 3 displayed a visible polar body (MII). The number of oocytes collected was positively correlated with the amount of tissue cryopreserved (p < 0.001) and negatively correlated with the age of the patients (p = 0.005). Oocytes were obtained regardless of menstrual cycle period or contraception. A total maturation rate of 31% was achieved, leading to the vitrification of at least one mature oocyte for half of the cohort. CONCLUSIONS: The study showed that a significant number of immature oocytes can be collected from excised ovarian tissue whatever the menstrual cycle phases and the age of the patients, even for prepubertal girls.

RESUMEN

OBJECTIVE: To analyse treatment outcomes after SET law enforcement and to evaluate the contribution of cryopreservation in a SET policy. MATERIAL: Embryo transfer cycles performed after the law enforcement (SET period) was retrospectively compared to the cycles performed before the law enforcement (DET period). RESULTS: Pregnancy and delivery rates after fresh transfer of SET and DET periods were comparable (31.7% versus 33.3% and 24.5% versus 26.2%, respectively, NS). Overall twin delivery rate is significantly decreased after the law enforcement (11.3% versus 22.4%, p < 0.001) but not in patients aged 36 to 39 years (20.3% versus 24%, NS). Frozen-thawed embryo cycles allowed similar cumulative pregnancy rate (30.6%, NS). Taking into account all frozen embryos still to be transferred, SET period offers a better overall pregnancy rate than the DET period (36.1% versus 32.3%, p < 0.01). CONCLUSIONS: The Belgian law allowed a dramatic reduction of twin deliveries especially for patients under 39 years. Cryopreservation maintains a similar cumulative pregnancy rate.

RESUMEN

OBJECTIVE: to assess the evidence from multidisciplinary simulation team training in obstetrics that integrates human's factors components on patient outcome. INTRODUCTION: It has been stated that simulation-based education has the potential to improve technical and nontechnical skills. Reports from enquiries into maternal and newborn adverse outcomes, highlight that the majority of incidents are due to a breakdown of communication and a lack of crisis resource management skills (CRM). It is therefore reasonable to think that a better training on teamwork based on simulation will ultimately improve obstetrics care. In order to explore further that idea, we conducted a literature review on patient outcome after a multidisciplinary simulation training in obstetrics. METHOD: Pubmed, Advances in health sciences education, BMC in medical education, BMC in pregnancy and Childbirth, BMJ open, BMJ Simulation and technology enhanced learning were searched from inception to May 2020 for full-text publications in English on interprofessional, multidisciplinary, obstetrics, simulation training, non-technical skills, CRM. Searches were limited to studies with a report on patient outcome after a multidisciplinary simulation program that included elements of CRM. RESULT: Out of the ten studies selected in our review, five were single site before and after prospective studies and five were cluster before and after randomized trials. All the single site studies reported a positive outcome in low and high resource countries. Three single site studies reported a reduction between 41 and 50 % of blood transfusion after simulation team training. Two single studies reported a reduction of maternal mortality by 34 % and a decrease in an adverse obstetrics index outcome from 0.052 to 0.048 with a p-value of 0.05. Cluster studies showed either no change or some improvement in patient outcomes such as a 37 % improvement on weighted obstetrics adverse outcome, a 17 % reduction in the incidence of PPH and a 47 % reduction in the incidence of retained placenta. Stillbirths rate was reduced by 34 % while newborn deaths was down by 62 %. There was also a 15 % reduction of maternal mortality in favor of the trained team after adjustment to the secular mortality trend. Neonatal death from 24 weeks during the first 24 h was also reduced by 83 % in the intervention site compare with an increase by 18 % in the control site. CONCLUSION: There is evidence that simulation team training that includes CRM is associated with better patient outcome. In order to consolidate this finding, appropriate methodology should be used in future studies with the support of health authorities.

RESUMEN

Among high-risk human papillomaviruses (HPV), HPV-16 infection is the most prevalent causative factor for cervical cancer. Beside other mucosal targets, HPV-16 was reported to infect the placenta and to replicate in trophoblastic cells. Since these cells share invasive properties of tumoral cells, they represent an ideal model to investigate several oncogenic processes. In the present work, we analyzed the impacts of HPV-16 E5, E6 and E7 oncoproteins on the trophoblastic model. Our results showed that E5 impaired the viability of trophoblastic and cervical cell lines but E6 and E7, favoring cell growth, neutralized the E5 cytotoxic effect. In addition, E5 decreased the adhesiveness of trophoblastic cells to the tissue culture plastic and to endometrial cells similarly as described previously for E6 and E7. E5 and E6 plus E7 increased also their migration and their invasive properties. Cells expressing HPV-16 early proteins under the control of the long control region endogenous promoter displayed growth advantage and were also more motile and invasive compared with control cells. Interestingly, the E-cadherin was downregulated in trophoblastic cells expressing E5, E6 and E7. Nuclear factor-kappaB and activator protein-1 activities were also enhanced. In conclusion, HPV-16 early proteins enhanced trophoblastic growth and intensify the malignant phenotype by impairing cell adhesion leading to increased cellular motile and invasive properties. HPV-16 E5 participated, with E6 and E7, in these changes by impairing E-cadherin expression, a hallmark of malignant progression.

RESUMEN

Until recently, only assisted reproduction was proposed to serodiscordant couples wishing to conceive. Nevertheless, recent publications have proposed unprotected sexual intercourse, targeting fertile days, for couples where antiretroviral treatment has lowered blood viral load to an undetectable level. Available data and the arguments for and against conception by safe sex versus the use of a strategy of unprotected sexual intercourse targeting fertile days are reviewed and analyzed. Although the rate of transmission of human immunodeficiency virus in serodiscordant couples in precise conditions (such as an undetectable viral load on treatment by highly active antiretroviral therapies and sexual intercourse limited to the fertile days) is very low, not zero, here we stress the various factors which can increase the risk of seroconversion in this particular population. In this context, it seems less cautious to abandon the recommendations of safe sex in serodiscordant couples desiring a child. The recourse to medically assisted procreation is advised, as long as evidence from further studies does not show that unprotected sexual intercourse, targeted to fertile days, does not have unexpected harmful consequences.

RESUMEN

OBJECTIVE: To retrospectively evaluate factors influencing human cytomegalovirus serologic status of couples consulting our fertility clinic. METHODS: Human cytomegalovirus individual serologic status of 3,227 women and 2,565 men was studied according to age, serologic status of the sexual partner, and presence of children in the family at entry in the clinic. Among 1,906 initially seronegative individuals, human cytomegalovirus seroconversions during follow-up were recorded and correlated to age, serologic status of the sexual partner, and presence of children aged younger than 3 years in the family. RESULTS: Human cytomegalovirus status at entry in the fertility clinic depended on age, but women were more frequently seropositive (54%) than men (43%), although they were younger (mean age 33 years for women and 37 years for men). The probability of seroconversion of women and men was significantly associated with the presence of children aged younger than 3 years; 35 of 217 women (16%) and 17 of 130 men (13%) living with children aged younger than 3 years seroconverted compared with 37 of 1,066 women (3.4%) and 16 of 493 men (3.2%) without children. Moreover, women's seroconversion was significantly associated with the seropositivity of the sex partner; 13 of 96 (13.5%) women with a cytomegalovirus seropositive partner seroconverted compared with 33 of 452 (7.3%) of those without such a partner. CONCLUSION: Our results suggest that human cytomegalovirus is sexually transmitted among couples in our fertility clinic. Safe sex practices should be included in hygiene precaution advice given to pregnant women to avoid human cytomegalovirus contamination. LEVEL OF EVIDENCE: II.

RESUMEN

BACKGROUND: The relationships between hedonic deficits, type D personality and suicidal ideation were explored in a group of medical students. METHODS: In a cross-sectional study, 382 medical students filled out several questionnaires measuring suicide risk, depression (using the Beck Depression Inventory, i.e. BDI), type D personality (using the type D personality scale-14, i.e. DS-14) and anhedonia (using the anhedonia subscale of the BDI, the Snaith Hamilton Pleasure Scale, the Anticipatory and Consummatory subscales of the Physical Anhedonia Scale). RESULTS: State anhedonia and, in particular, recent change of state anhedonia and not trait anhedonia was significantly associated with suicidal ideation, specifically when depression was controlled for. Negative affectivity component of type D personality and anhedonia were independent predictors of suicidal ideation even when depression was controlled for. Loss of pleasure and not loss of interest was a significant predictor of suicidal ideation. CONCLUSIONS: Change of state anhedonia and its component of loss of pleasure measuring dissatisfaction in life could be a risk factor of suicidal ideation in medical students. Dissatisfaction, particularly in the medical course, could be a strong predictor of suicidal ideation in medical students.

RESUMEN

BACKGROUND: The relationships between anhedonia and suicidal ideation or suicide attempts were explored in a large sample of physicians using the interpersonal psychological theory of suicide. We tested two hypotheses: firstly, that there is a significant relationship between anhedonia and suicidality and, secondly, that anhedonia could mediate the relationships between suicidal ideation or suicide attempts and thwarted belongingness or perceived burdensomeness. METHODS: In a cross-sectional study, 557 physicians filled out several questionnaires measuring suicide risk, depression, using the abridged version of the Beck Depression Inventory (BDI-13), and demographic and job-related information. Ratings of anhedonia, perceived burdensomeness and thwarted belongingness were then extracted from the BDI-13 and the other questionnaires. RESULTS: Significant relationships were found between anhedonia and suicidal ideation or suicide attempts, even when significant variables or covariates were taken into account and, in particular, depressive symptoms. Mediation analyses showed significant partial or complete mediations, where anhedonia mediated the relationships between suicidal ideation (lifetime or recent) and perceived burdensomeness or thwarted belongingness. For suicide attempts, complete mediation was found only between anhedonia and thwarted belongingness. When the different components of anhedonia were taken into account, dissatisfaction-not the loss of interest or work inhibition-had significant relationships with suicidal ideation, whereas work inhibition had significant relationships with suicide attempts. CONCLUSIONS: Anhedonia and its component of dissatisfaction could be a risk factor for suicidal ideation and could mediate the relationship between suicidal ideation and perceived burdensomeness or thwarted belongingness in physicians. Dissatisfaction, in particular in the workplace, may be explored as a strong predictor of suicidal ideation in physicians.
