RESUMEN

AIM: The objective of this meta-analysis was to evaluate obstetric outcomes in gestational diabetes mellitus (GDM) patients treated with flexible management based on intrauterine ultrasound fetal growth (FMIUFG) or strict maternal glycemic adjustment (SMGA). METHODS: We performed a comprehensive systematic review of electronic databases for randomized clinical trials (RCTs) comparing obstetrics outcomes of singleton GDM patients managed according to FMIUFG or SMGA. The review protocol was registered in PROSPERO (CRD497888). Searches were conducted in PubMed, Embase, Cochrane, and LILACS. Primary outcomes were gestational age at delivery and birth weight. Random-effect model meta-analyses were used to minimize the effects of uncertainty associated with inter-study variability. Results are reported as standardized mean differences (SMDs) or as odds ratios (ORs) and their 95% confidence interval (CI). Heterogeneity between studies was estimated using the I2 statistic. The Cochrane Risk of Bias Scale was used to assess the quality of studies. There were five RCTs with low to moderate risk of bias, including 450 patients managed according to the FMIUFSG and 381 according to the SMGA. RESULTS: The macrosomia (birthweight >4000 g) rate was lower in pregnancies managed according to FMIUFG than SMGA adjustments (OR: 0.34; 95%CI: 0.16, 0.71). There were no significant differences in hypertensive disorder, cesarean section, neonatal intensive care unit admission, and large newborn for gestational age rates. CONCLUSIONS: The macrosomia rate was lower in women managed with the FMIUFG. There were no significant differences in other obstetric and neonate outcomes.

RESUMEN

BACKGROUND: The increasing prevalence of obesity worldwide poses a significant threat to reproductive function owing, in part, to hormonal disturbances caused by negative feedback between excess adiposity and the hypothalamic-pituitary-ovarian axis. Consequently, finding the most appropriate strategies to lose weight and improve ovulation in women with overweight or obesity is a clinically relevant matter that needs to be investigated. A comprehensive comparison of the independent and combined efficacy of lifestyle and/or pharmacological interventions on BMI, ovulation, and hormonal profile in women with overweight or obesity at risk of anovulatory infertility would facilitate improving fertility strategies in this population. OBJECTIVE AND RATIONALE: This study aimed to evaluate the comparative efficacy of exercise, diet, and pharmacological interventions on BMI, ovulation, and hormonal profile in reproductive-aged women with overweight or obesity. SEARCH METHODS: A systematic review was performed by searching PubMed, Scopus, Web of Science, PsycINFO, and Cochrane Library up to 14 December 2023, for randomized controlled trials assessing the effects of exercise, diet and/or pharmacological interventions (i.e. weight-lowering drugs or ovulation inducers) on BMI, ovulation, and/or hormonal profile in reproductive-aged women with overweight or obesity. We performed frequentist random-effect network meta-analyses and rated the certainty of the evidence. The primary outcomes were BMI and ovulation rate, and the secondary outcomes were serum reproductive hormone levels (gonadotrophins, androgens, or oestrogens). We performed sensitivity analyses, including the studies that only involved women with PCOS. OUTCOMES: Among 1190 records screened, 148 full texts were assessed for eligibility resulting in 95 trials (9910 women), of which 53% presented a high or unclear risk of bias. The network meta-analyses revealed that, compared to control: diet combined with weight-lowering drugs (mean difference (MD) -2.61 kg/m2; 95% CI -3.04 to -2.19; τ2 = 0.22) and adding exercise (MD -2.35 kg/m2; 95% CI -2.81 to -1.89; τ2 = 0.22) led to the greatest decrease in BMI; exercise combined with diet and ovulation inducers (risk ratio (RR) 7.15; 95% CI 1.94-26.40; τ2 = 0.07) and exercise combined with diet and weight-lowering drugs (RR 4.80; 95% CI 1.67-13.84; τ2 = 0.07) produced the highest increase in ovulation rate; and exercise combined with diet and weight-lowering drugs was the most effective strategy in reducing testosterone levels (standardized mean difference (SMD) -2.91; 95% CI -4.07 to -1.74; τ2 = 2.25), the third most effective strategy in increasing sex hormone-binding globulin levels (SMD 2.37; 95% CI 0.99-3.76; τ2 = 2.48), and it was coupled with being ranked first in terms of free androgen index reduction (SMD -1.59; 95% CI -3.18 to 0.01; τ2 = 1.91). The surface under the cumulative ranking curve scores suggested that: diet combined with weight-lowering drugs is the strategy most likely (94%) to produce the highest BMI reduction; and exercise combined with diet and ovulation inducers is the strategy most likely (89%) to produce the highest ovulation rate improvement. The sensitivity analyses, which exclusively included studies involving women diagnosed with PCOS, were consistent with the results presented above. WIDER IMPLICATIONS: Overall, the findings of this network meta-analysis indicate that the combination of exercise, diet, and pharmacological interventions is effective for weight loss, improving ovulation, and normalizing the androgen levels of women with overweight or obesity. Although higher quality studies are needed, these results support that the optimal treatment strategy for women with overweight or obesity wishing to conceive must consider exercise, diet, and pharmacological interventions during the shared decision-making process.

RESUMEN

AIM: We performed a systematic review and meta-analysis to assess whether telomerase activity and telomere length are associated with breast cancer. METHODS: PubMed, Web of Science, Embase, LILACS, Scielo, Embase, and CNKI databases were searched to obtain relevant articles published through May 10, 2023, following PRISMA guidelines and a registered PROSPERO protocol (CRD42022335402). We included observational studies reporting telomerase activity or telomere length in patients with breast cancer compared with women with benign lesions or normal tissue (control women). The Newcastle-Ottawa Scale was used to evaluate the quality of studies. Data were expressed as odds ratios (OR) and 95 % confidence intervals (CI). Random effects and inverse variance methods were used to meta-analyze associations. The I2 test was used to assess heterogeneity. RESULTS: The meta-analysis of telomerase shows significantly greater activity in patients with breast cancer than in those without malignancies (OR = 23.46, 95 % CI 14.07-39.11, p < 0.00001, I2 = 72 %). There were non-significant differences in relative telomere length (OR = 1.16, 95 % CI = 0.90-1.49, p = 0.26, I2 = 86 %) and leukocyte telomere length (OR = 2.32, 95 % CI = 0.89-6.08, p = 0.09, I2 = 98 %) between women with and without breast cancer. In subgroup analyses by world regions of studies, both telomerase activity and telomere length displayed the same trends as in their respective meta-analyses. In sensitivity analyses, variables showed their respective same trends. CONCLUSION: Telomerase activity is higher in patients with breast cancer than in women without malignancies. There were no significant differences in either relative telomere length or leukocyte telomere length in women with and without breast cancer. PROSPERO protocol CRD42022335402.

RESUMEN

INTRODUCTION: Teriflunomide is a once-daily oral immunomodulator approved for relapsing forms of multiple sclerosis (MS) or relapsing-remitting multiple sclerosis (RRMS; depending on the local label), based on extensive evidence from clinical trials and a real-world setting on efficacy, tolerability and patient-reported benefits. The TERICARE study assessed the impact of teriflunomide treatment over 2 years on health-related quality of life (HRQoL) and some of the most common and disabling symptoms of MS, such as fatigue and depression. METHODS: This prospective observational study in Spain included RRMS patients treated with teriflunomide for ≤ 4 weeks. The following patient-reported outcomes (PROs) were collected at baseline and every 6 months for 2 years: the 29-item Multiple Sclerosis Impact Scale version 2 (MSIS-29), the 21-item Modified Fatigue Impact Scale (MFIS-21), the Beck Depression Inventory (BDI-II), the Short Form (SF)-Qualiveen and the Treatment Satisfaction Questionnaire for Medication v1.4 (TSQM). Annualised relapse rate (ARR), disability progression according to the Expanded Disability Status Scale (EDSS), and no evidence of disease activity (NEDA-3) were also assessed. RESULTS: A total of 325 patients were analysed. Patients had a mean (SD) age of 43.2 years (10.4), a mean baseline EDSS score of 1.75 (1.5), a mean number of relapses in the past 2 years of 1.5 (0.7), and 64% had received prior disease-modifying therapy (DMT). Patients showed significant improvements in the psychological domain of MSIS-29 from 35.9 (26.6) at baseline to 29.4 (25.5) at 18 months (p = 0.004) and 29.0 (24.6) at 24 months (p = 0.002). Levels of fatigue and depression were also reduced. After 2 years of treatment with teriflunomide, ARR was reduced to 0.17 (95% CI 0.14-0.21) from the baseline of 0.42 (95% CI 0.38-0.48), representing a 60.1% reduction. Mean EDSS scores remained stable during the study, and 79.9% of patients showed no disability progression. 54.7% of patients achieved NEDA-3 in the first 12 months, which increased to 61.4% during months 12-24. Patients reported increased satisfaction with treatment over the course of the study, regardless of whether they were DMT naive or not. CONCLUSION: Teriflunomide improves psychological aspects of HRQoL and maintains low levels of fatigue and depression. Treatment with teriflunomide over 2 years is effective in reducing ARR and disability progression.

RESUMEN

Leishmania parasites cause outstanding levels of morbidity and mortality in many developing countries in tropical and subtropical regions. Numerous gene expression profiling studies have been performed comparing different Leishmania species' life-cycles and stage forms in regard to their distinct infective ability. Based on expression patterns, homology to human orthologues, in silico HLA-binding predictions, and annotated functions, we were able to select several vaccine candidates which are currently under study. One of these candidates is the Leishmania infantum ubiquitin-conjugating enzyme E2 (LiUBC1), whose relative levels, subcellular location, in vitro infectivity in the U937 myeloid human cell model, and protection levels in Syrian hamsters against L. infantum infection were studied herein. LiUBC1 displays a low level of similarity with the mammalian orthologs and relevant structure differences, such as the C-terminal domain, which is absent in the human ortholog. LiUBC1 is present in highly infective promastigotes. Knock-in parasites overexpressing the enzyme increased their infectivity, according to in vitro experiments. Syrian hamsters immunized with the recombinant LiUBC1 protein did not show any parasite burden in the spleen, unlike the infection control group. The IFN-γ transcript levels in splenocytes were significantly higher in the LiUBC1 immunized group. Therefore, LiUBC1 induced partial protection against L. infantum in the Syrian hamster model.

RESUMEN

BACKGROUND: Previous studies have investigated weight loss caused by exercise following bariatric surgery. However, in most cases, the training program is poorly reported; the exercise type, volume, and intensity are briefly mentioned; and the sample size, selection criteria, and follow-up time vary greatly across studies. PURPOSE: The EFIBAR study aims to investigate over 1 year the effects of a 16-week supervised exercise program, initiated immediately after bariatric surgery, on weight loss (primary outcome), body composition, cardiometabolic risk, physical fitness, and quality of life in patients with severe/extreme obesity. MATERIAL AND METHODS: The EFIBAR study is a parallel-group, superiority, randomized controlled trial (RCT), comprising 80 surgery patients. Half of the participants, randomly selected, perform a 16-week supervised exercise program, including both strength and aerobic training, starting immediately after the surgery (7-14 days). For each participant, all primary and secondary outcomes are measured at three different time points: (i) before the surgery, (ii) after the intervention (≈4 months), and (iii) 1 year after the surgery. CONCLUSION: The EFIBAR study will provide new insights into the multidimensional benefits of exercise in adults with severe/extreme obesity following bariatric surgery. TRIAL REGISTRATION: EFIBAR randomized controlled trial was prospectively registered at Clinicaltrials.gov (NCT03497546) on April 13, 2018.

RESUMEN

BACKGROUND: Severe and morbid obesity are increasing globally, particularly in women. As BMI increases, the likelihood of anovulation is higher. The primary aim of the EMOVAR clinical trial is to examine, over the short (16 weeks) and medium (12 months) term, the effects of a supervised physical exercise program (focused primarily on aerobic and resistance training) on ovarian function in women with severe/morbid obesity who have undergone bariatric surgery. Secondary objectives are to examine the effects of the intervention on chronic inflammation, insulin resistance, arterial stiffness, physical fitness, and health-related quality of life. METHODS: This is a randomized controlled trial in which ∼40 female bariatric surgery patients, aged between 18 and 45 years old, will be included. Participants assigned to the experimental group will perform a total of 48 sessions of supervised concurrent (strength and aerobic) training (3 sessions/week, 60 min/session) spread over 16 weeks. Patients assigned to the control group will receive lifestyle recommendations. Outcomes will be assessed at baseline, week 16 (i.e., after the exercise intervention) and 12 months after surgery. The primary outcome is ovarian function using the Sex-Hormone Binding Globuline, measured in serum. Secondary outcomes are serum levels of anti-mullerian hormone, TSH, T4, FSH, LH, estradiol, prolactine, and free androgen index, as well as oocyte count, the diameters of both ovaries, endometrial thickness, and uterine arterial pulsatility index (obtained from a transvaginal ultrasound), the duration of menstrual bleeding and menstrual cycle duration (obtained by personal interview) and hirsutism (Ferriman Gallwey Scale). Other secondary outcomes include serum markers of chronic inflammation and insulin resistance (i.e., C-reactive protein, interleukin 6, tumor necrosis factor-alpha, leptin, glomerular sedimentation rate, glucose, insulin and the HOMA-IR), arterial stiffness, systolic, diastolic and mean blood pressure, body composition, and total weight loss. Physical fitness (including cardiorespiratory fitness, muscular strength, and flexibility), health-related quality of life (SF-36 v2) and sexual function (Female Sexual Function Index) will also be measured. DISCUSSION: This study will provide, for the first time, relevant information on the effects of exercise training on ovarian function and underlying mechanisms in severe/morbid obese women following bariatric surgery. TRIAL REGISTRATION NUMBER: ISRCTN registry (ISRCTN27697878).

RESUMEN

OBJECTIVE: To assess vulvovaginal symptoms and urinary incontinence in postmenopausal women. Secondarily to evaluate factors related to the severity of vulvovaginal symptoms and the internal consistency of the used tools. METHODS: In this cross-sectional study, the Spanish language version of the 21-item Vulvovaginal Symptoms Questionnaire (VSQ) and the 3-item International Consultation on Incontinence Questionnaire (ICIQ-SF) were applied to 122 postmenopausal Spanish women aged 45 to 75 years. RESULTS: Mean age of the whole sample was 59.5 ±â€Š4.9 years; 89.3% had natural menopause, 77.9% reported vulvovaginal symptoms, 54.9% had urinary incontinence, 54.1% were sexually active, and 77.0% currently had a partner. Calculated Cronbach's alpha coefficients were 0.87 and 0.88 for the VSQ and the ICIQ-SF, respectively. Multiple linear regression analysis determined that total VSQ scores (more severe vulvovaginal symptoms) were positively correlated with female age, parity, surgical menopause, being sexually active, economic problems, phytoestrogen use, and more severe urinary incontinence. An inverse correlation was found with urban residency and time since menopause onset. CONCLUSIONS: Internal consistency of the VSQ and the ICIQ-SF was good in this postmenopausal sample in which age, sexual activity, urinary incontinence, drug use, and other personal aspects were important covariates determining the severity of vulvovaginal symptoms.

RESUMEN

OBJECTIVE: To investigate serum inflammatory markers in singleton gestations complicated with threatened preterm labour (TPL). METHODS: Pregnant women complicated with TPL (n = 61) were recruited to measure maternal serum levels of a panel of cytokines and C-reactive protein and then compared to controls without TPL, matched for gestational age (n = 64) and term pregnancies in the prodromal phase of labour (PPL) (n = 31). In addition, baseline cytokine levels were compared among cases and controls according to the outcome. RESULTS: Women with TPL displayed higher CRP and white blood counts levels together with lower granulocyte macrophage colony-stimulating factor (GMC-SF) compared to both controls without TPL and to term gestations in the PPL. Also, interleukin 10 (IL-10), IL-6, IL-7, IL-8 and tumour necrosis alpha (TNF-α) levels were found significantly higher in TPL cases as compared to controls without TPL and term women in the PLL. Baseline cytokine levels (except IL-10) were higher among TPL cases who later delivered preterm. TPL cases delivering preterm displayed lower GMC-SF levels as compared to those delivering at term. Multivariate analysis found that gestational age at birth positively correlated with cervical length and inversely with CRP, IL-6 and TNF-α levels (p < 0.0001). CONCLUSIONS: TPL and preterm birth were related to inflammatory changes in the maternal side that correlate with cervical shortening and the initiation of uterine contractions.

RESUMEN

Objectives: The level of environmental contamination generated during preparation and administration of hazardous drugs using different valve closed-systems and their combinations was compared. The actual impact on the overall time of preparation of cytostatics and the economic cost of the different modalities were also compared. Methods: Comparative study of the preparation of fluorescein mixtures with different modalities of valve closed-system combinations. Environmental contamination was detected in critical points of connection, and in splashes produced at any other points. The main variable was qualitative detection of contamination by splashes through ultraviolet light when modalities with or without a connector were compared. A final number of 160 mixtures were prepared to detect differences of at least 5%. Results: Splashes were produced in 7 preparations without a connector (p = 0.015). No significant differences (p = 0.445) were detected either in the use of a supporting vial spike vs an anchoring spike, or in the ChemoCLAVE® system vs valve systems with Fleboflex® solutions. Contamination at any critical point was produced in all preparations. The use of a supporting vial spike, syringe connector and bag solution with Luer connection was the most efficient modality. Conclusions: A syringe connector is needed to guarantee a closed system. Anchoring spikes do not show higher advantages as compared with supporting vial spikes. Fleboflex® solutions with Luer bags are more efficient than ChemoCLAVE® and show similar safety. However, connections of these closed systems are not leak-tight, and it is therefore important to continue studies of contamination of the different closed system transfer devices (AU)


Objetivo: Comparar la contaminación generada durante la elaboración y administración de fármacos peligrosos con diferentes componentes de sistemas cerrados y de manera secundaria, seleccionar el sistema más eficiente. Material y métodos: Estudio comparativo de elaboración de mezclas de fluoresceína con diferentes combinaciones de sistemas cerrados de tipo valvular. Se consideró contaminación ambiental la detectada en los puntos críticos de conexión y las salpicaduras generadas en cualquier otro punto distinto. La variable principal fue la detección cualitativa mediante luz ultravioleta de contaminación por salpicaduras al comparar las modalidades con y sin conector. Se calculó un tamaño muestral de 160 preparaciones por modalidad, para detectar diferencias de al menos un 5%. Resultados: Se produjeron salpicaduras en 7 preparaciones, todas sin conector (p = 0,015). No se encontraron diferencias entre utilizar punzón de apoyo o de anclaje (p = 0,445), ni entre el sistema ChemoCLAVE® vs sistema valvular con sueros Fleboflex®. En todas las preparaciones se produjo contaminación en algún punto crítico. La utilización de punzones de apoyo, conectores y sueros luer se ha identificado como la modalidad más eficiente. Conclusiones: Es importante utilizar el conector de jeringa para que el sistema sea completamente cerrado. El uso de punzones de anclaje no parece presentar ventajas frente a los de apoyo y la combinación con los sueros Fleboflex® presenta una seguridad similar al sistema ChemoCLAVE®. Sin embargo, las conexiones de estos sistemas no son secas y, por tanto, es importante continuar con estudios de contaminación que comparen diferentes sistema (AU)

RESUMEN

Missing self recognition makes cancer sensitive to natural killer cell (NKc) reactivity. However, this model disregards the NKc licensing effect, which highly increases NKc reactivity through interactions of inhibitory killer cell immunoglobulin-like receptors (iKIR) with their cognate HLA-I ligands. The influence of iKIR/HLA-ligand (HLA-C1/C2) licensing interactions on the susceptibility to and progression of plasma cell (PC) dyscrasias was evaluated in 164 Caucasian patients and 286 controls. Compared to controls, myeloma accumulates KIR2DL1-L2+L3- genotypes (2.8% vs. 13.2%, p < 0.01, OR = 5.29) and less diverse peripheral repertoires of NKc clones. Less diverse and weaker-affinity repertoires of iKIR2D/HLA-C licensing interactions increased myeloma susceptibility. Thus, the complete absence of conventional iKIR2D/HLA-C licensing interactions (KIR2DL1-L2+L3-/C2C2, 2.56% vs. 0.35%; p < 0.05; OR = 15.014), single-KIR2DL3+/C1+ (20.51% vs. 10.84%; p < 0.05; OR = 2.795) and single-KIR2DL2+/C1+ (12.82% vs. 4.9%; p < 0.01; OR = 5.18) interactions were over-represented in myeloma, compared to controls. Additionally, KIR2DL1-L2+L3- (20% vs. 83%, p < 0.00001) as well as KIR3DL1- (23% vs. 82%, p < 0.00001) genotypes had a dramatic negative impact on the 3-y progression-free survival (PFS), particularly in patients with low-tumor burden. Remarkably, myeloma-PCs, compared to K562 and other hematological cancers, showed substantial over-expression of HLA-I ("increasing-self" instead of missing-self), including HLA-C, and mild expression of ligands for NKc activating receptors (aRec) CD112, CD155, ULBP-1 and MICA/B, which apparently renders myeloma-PCs susceptible to lysis mainly by licensed NKc. KIR2DL1-L2+L3-/C2C2 patients (with no conventional iKIR2D/HLA-C licensing interactions) lyse K562 but barely lyse myeloma-PCs (4% vs. 15%; p < 0.05, compared to controls). These results support a model where immunosurveillance of no-missing-self cancers, e.g., myeloma, mainly depends on NKc licensing.

RESUMEN

OBJECTIVE AND METHODS: To measure 25-hydroxyvitamin D [25(OH)D] and C-reactive protein (CRP) serum levels in singleton gestations complicated with threatened preterm labour (TPL, n = 59) and compare to normal controls matched for gestational age (n = 64). Cases were treated after blood sample according to institutional protocol. Also, analyte levels were compared among cases according to the outcome. RESULTS: Mean serum 25(OH)D levels were similar between cases and controls, with median white blood cell count and CRP levels found significantly higher in TPL cases. Women with TPL delivering preterm displayed shorter mean cervical lengths along with higher CRP and lower 25(OH)D serum levels when compared to those delivering at term. Two multiple linear regression models were constructed to analyse factors related to gestational age at delivery (pooled analysis and only those with TPL). In both models, gestational age positively correlated to cervical length and inversely to CRP levels; whereas, in the TPL model, only 25(OH)D levels correlated positively. CONCLUSION: Women complicated with TPL showed similar serum 25(OH)D yet higher CRP levels as compared to controls. TPL cases delivering preterm displayed lower 25(OH)D and higher CRP correlated levels.

RESUMEN

BACKGROUND: Alcoholic cirrhosis (AC) is a common cause of death among individuals abusing alcohol. In the last resort, liver transplantation (LT) is considered the only solution to save the patient's life, generating socioeconomic and public health problems. Clinical and sociodemographic characteristics, rejection frequency, and short- and long-term graft survival are not well known in end-term AC patients undergoing LT. The aim was to determine the sociodemographic and clinical characteristics, their incidence in LT, main pre- and posttransplant complications, and short- and long-term post-transplant graft survival in AC patients in southeastern Spain. METHODS: The medical records of 1,026 patients who underwent LT over the last 23 years were retrospectively reviewed, and demographic data and posttransplant survivals were analyzed and compared. Biochemical characteristics, major pre- and posttransplant complications and short- and long-term survivals were analyzed in a total of 398 male patients with AC undergoing LT. RESULTS: AC and viral cirrhosis are the main indications for LT in our study. Mostly represented in our study are AC men without associated viral infections with a mean age of 53.06 years. Main pretransplant complications in AC patients are ascites (78.3%) and encephalopathy (43.5%), while acute graft rejection is the most common liver posttransplant complication (26.6%), nevertheless with low graft loss frequency (1.1%). AC and autoimmune cirrhosis show the best posttransplant survival in both the short and long term. Patients with AC included on the waiting list for LT were Child-Pugh class B (52.1%) and Model for End-Stage Liver Disease score of 10 to 19 (71.2%). The highest percentage of AC patient survival was observed at 1 year posttransplant (81.2%) and progressively decreased over time up to 10 years posttransplant (69.6%). Pretransplant complications such as ascites and encephalopathy did not have an influence on the percentage of posttransplant survivals, although better survival rates were observed in nonviral AC patients. CONCLUSIONS: AC without viral infections is the main indication for LT in southeastern Spain although its frequency has decreased in last decade. AC is a good indication for LT for its high survival rate and few posttransplant complications. Despite having a high percentage of pretransplant complications (ascites and encephalopathy) but does not appear to influence survivals being observed posttransplant survival rates above those expected. Conversely, viral infections in the patient with AC decrease patient survivals. The main future goals are design new strategies to detect, treat, and reduce AC frequency in our population and know alcoholic recidivism rate posttransplant in our population.

RESUMEN

OBJECTIVE: To assess the risk of obstructive sleep apnea-hypopnea syndrome (OSAHS) and related factors at the end of pregnancy using the Berlin questionnaire. METHODS: A total of 367 women at the end of pregnancy (median gestational age 39 weeks) were interviewed with the Berlin questionnaire and a general survey containing maternal socio-demographic and anthropometric information. Neonatal outcome data were also assessed. RESULTS: Median age for the whole sample was 31 years. According to the Berlin questionnaire, 39.8% were positive for high risk of OSAHS. Upon bivariate analysis, higher risk of OSAHS was significantly related to church attendance, and higher pre-pregnancy body mass index (BMI), current BMI, weight, neck and arm circumference and systolic blood pressure at survey. Logistic regression analysis found that higher maternal pre-pregnancy BMI (OR 2.71 95% CI 1.84-4.00, p < 0.0001) and higher maternal weight at survey (OR 3.02, 95% CI 1.78-5.17, p < 0.0001) were significantly related to a higher risk of OSAHS. CONCLUSION: The risk of OSAHS is relatively high at the end of pregnancy and related to a higher pre-pregnancy BMI and higher maternal weight at survey. Further studies are needed to confirm our results with a diagnostic tool, such as polysomnography or another similar yet less complicated to carry out procedure.

RESUMEN

El útero septo, presente en el 1% de la población en edad fértil, es la malformación uterina más frecuente, pero también la que da lugar a peores resultados reproductivos. La afección obstétrica que con más frecuencia se asocia a esta anomalía mülleriana es aquella relacionada con el mantenimiento de la gestación, como son los abortos tardíos o el parto pretérmino. Presentamos el caso de una paciente en la que la existencia de un septo en la cavidad uterina dio lugar a una microcefalia fetal como consecuencia del atrapamiento de la cabeza fetal entre el septo y una de las paredes uterinas. (AU)


Septate uterus, which occurs in approximately 1% of fertile women, is considered the most common uterine anomaly but is associated with the poorest reproductive results. Uterine anomalies are especially associated with difficulty in maintaining a pregnancy to full term, often leading to late miscarriage or preterm delivery. We present a case of fetal microcephaly in a woman with septate uterus as a consequence of trapping of the fetal head between the septum and one of the uterine walls (AU)

RESUMEN

OBJECTIVE: This study aims to assess resilience, depressed mood, and menopausal symptoms in postmenopausal women. METHODS: In this cross-sectional study, 169 postmenopausal women aged 48 to 68 years were asked to fill out the Wagnild and Young Resilience Scale (WYRS), the Center for Epidemiologic Studies Depression Scale (CESD-10), the Menopause Rating Scale (MRS), and a questionnaire containing personal and partner sociodemographic data. RESULTS: The median [interquartile range] age of participating women was 54 [10.0] years. Among the women, 55.6% had increased body mass index, 76.9% had a partner, 17.8% were current smokers, 14.2% had hypertension, 25.4% used psychotropic drugs, and 13.0% used hormone therapy. Forty-five percent of the women had depressed mood (CESD-10 scores ≥10), and 34.9% had severe menopausal symptoms (total MRS scores ≥17). Less resilience (lower WYRS scores) correlated with depressed mood (higher CESD-10 scores) and severe menopausal symptoms (higher total, psychological, and urogenital MRS scores). Multiple linear regression analysis determined that WYRS scores positively correlated with exercising regularly and inversely correlated with CESD-10 scores (depressed mood). CESD-10 scores positively correlated with somatic and psychological MRS subscale scores and inversely correlated with WYRS scores (less resilience). CONCLUSIONS: In this postmenopausal sample, depressed mood and participation in regular exercise correlate with lower and higher resilience, respectively. Depressed mood is associated with the severity of menopausal symptoms (somatic and psychological).

RESUMEN

OBJECTIVE: To assess long-term effects of different hormone replacement therapy (HRT) regimens on mammographic density. METHODS: One hundred sixty-five postmenopausal women were treated with the same HRT during 5 years: 38 received transdermal estradiol, 78 cyclic combined therapy and 49 continuous combined therapy. Mammograms were obtained at baseline, at 1-year and 5-year treatment. Breast density changes were categorized as slight focal increased density, considerable focal increased density, slight diffuse increased density and considerable diffuse increased density. RESULTS: Mammographic density increased in 7.9% of women receiving estrogen alone versus 25.2% of women receiving combined therapy (p < 0.022) during 1 year, and in 7.9% of women versus 28.3% of women (p < 0.009) after 5 years of therapy, respectively. There were significant statistical differences in women treated with estrogen alone versus those treated with combined HRT after 1 and 5 years. After 5 years of HRT, breast density increased 21.8% in women receiving cyclic combined therapy versus 38.8% in those under continuous combined therapy (p < 0.039). CONCLUSION: An increase in breast density is significantly more frequent in women receiving combined estrogen-progestin therapy than in women receiving estrogen alone. There are differences between cyclic and continuous combined therapy at 5 years of treatment.

RESUMEN

OBJECTIVE: To develop a short 10 item version of the original menopause Cervantes Scale (CS) in order to assess menopausal symptoms in a large cohort of mid-aged Colombian women. METHODS: Reliability of the new short tool was assessed through internal consistency determination (Cronbach's alpha values) and intra-class correlation coefficient (ICC) analysis. Ten items out of the 31 composing the original CS were selected according to their clinical relation with menopausal symptoms. Subsequently the short tool was used to assess menopausal symptoms and related factors among 1739 mid-aged women. RESULTS: The CS-10 displayed a mean (±SD) ICC value of 0.45 (±0.06) and a Cronbach's alpha of 0.778 suggesting good internal reliability. For the entire sample median [interquartile range] CS-10 global scores were 10.0 [12.0], and for pre-, peri- and postmenopausal women: 8.0 [9.2], 9.0 [9.0] and 14.0 [14.0], respectively. Median global CS-10 scores significantly increased with menopausal status, marital status and ethnicity. Multiple linear regression analysis determined that higher global CS-10 scores (worse quality of life) correlated with age, parity, years since menopause, body mass index, ethnics (black) and smoking habit. CONCLUSION: The CS-10 seems to be a simple instrument that may aid everyday clinical consultation and help at performing an accurate diagnosis of menopause-related symptoms. Further studies are needed to confirm our preliminary findings.
