Background: In Nigeria, the relationship between spousal violence and pregnancy termination had not been adequately explored. Objectives: To assess the prevalence of spousal violence, and examine the relationship between spousal violence and pregnancy termination. Methods: Data on spousal violence among ever married women was extracted from the 2013 Nigeria Demographic and Health Survey. The outcome variable is pregnancy termination. The explanatory variables were the type of spousal violence experienced by the women in the last 12 months preceding the survey. Descriptive statistical analysis and binary logistic regression were applied using stata version 12. Results: Results show that 13.8% of women had ever terminated pregnancy; 19.9% had ever experienced at least one type of spousal violence; and women who had ever terminated pregnancy had higher prevalence of all types of spousal violence. Women who had ever experienced spousal physical violence were 9% more likely to experience pregnancy termination (OR=1.09; CI: 1.03-2.86); and women who had ever experienced spousal emotional violence were 33% more likely to experience pregnancy termination (OR=1.33; CI: 0.97-1.95). Conclusions: Spousal violence is significantly related to pregnancy termination. Improving women’s sexual and reproductive health in the country requires fresh initiatives that address spousal violence to further reduce women’s exposure to pregnancy termination.

Background and Purpose—High blood pressure (BP) is common in acute ischemic stroke and associated independently with a poor functional outcome. However, the management of BP acutely remains unclear because no large trials have been completed. Methods—The factorial PRoFESS secondary stroke prevention trial assessed BP-lowering and antiplatelet strategies in 20 332 patients; 1360 were enrolled within 72 hours of ischemic stroke, with telmisartan (angiotensin receptor antagonist, 80 mg/d, n647) vs placebo (n713). For this nonprespecified subgroup analysis, the primary outcome was functional outcome at 30 days; secondary outcomes included death, recurrence, and hemodynamic measures at up to 90 days. Analyses were adjusted for baseline prognostic variables and antiplatelet assignment. Results—Patients were representative of the whole trial (age 67 years, male 65%, baseline BP 147/84 mm Hg, small artery disease 60%, NIHSS 3) and baseline variables were similar between treatment groups. The mean time from stroke to recruitment was 58 hours. Combined death or dependency (modified Rankin scale: OR, 1.03; 95% CI, 0.84–1.26; P0.81; death: OR, 1.05; 95% CI, 0.27–4.04; and stroke recurrence: OR, 1.40; 95% CI, 0.68–2.89; P0.36) did not differ between the treatment groups. In comparison with placebo, telmisartan lowered BP (141/82 vs 135/78 mmHg, difference 6 to 7 mmHg and 2 to 4 mmHg; P0.001), pulse pressure (3 to 4 mmHg; P0.002), and rate-pressure product (466 mmHg.bpm; P0.0004). Conclusion—Treatment with telmisartan in 1360 patients with acute mild ischemic stroke and mildly elevated BP appeared to be safe with no excess in adverse events, was not associated with a significant effect on functional dependency, death, or recurrence, and modestly lowered BP.

Background: Prolonged empiric antibiotics therapy in neonates results in several adverse consequences including widespread antibiotic resistance, late onset sepsis (LOS), necrotizing enterocolitis (NEC), prolonged hospital course (HC) and increase in mortality rates. Objectives: To assess the risk factors and the outcome of prolonged empiric antibiotic therapy in very low birth weight (VLBW) newborns. Materials and Methods: Prospective study in VLBW neonates admitted to NICU and survived > 2 W, from July 2011 - June 2012. All relevant perinatal and postnatal data including duration of antibiotics therapy (Group I < 2W vs Group II > 2W) and outcome up to the time of discharge or death were documented and compared. Results: Out of 145 newborns included in the study, 62 were in group I, and 83 in Group II. Average duration of antibiotic therapy was 14 days (range 3 - 62 days); duration in Group I and Group II was 102.3 vs 25.510.5 days. Hospital stay was 22.311.5 vs 44.3 14.7 days, respectively. Multiple regression analysis revealed following risk factors as significant for prolonged empiric antibiotic therapy: VLBW especially < 1000 g, (P < 0.001), maternal Illness (P = 0.003), chorioamnionitis (P = 0.048), multiple pregnancy (P = 0.03), non-invasive ventilation (P < 0.001) and mechanical ventilation (P < 0.001). Seventy (48.3%) infants developed LOS; 5 with NEC > stage II, 12 (8.3%) newborns died. Infant mortality alone and with LOS/NEC was higher in group II as compared to group I (P < 0.002 and < 0.001 respectively). Conclusions: Prolonged empiric antibiotic therapy caused increasing rates of LOS, NEC, HC and infant mortality

OBJECTIVES: Most studies reporting evidence of adverse effects of lead and cadmium on the ability to balance have been conducted in high-exposure groups or have included adults. The effects of prenatal exposure have not been well studied, nor have the effects in children been directly studied. The aim of the study was to identify the associations of lead (in utero and in childhood) and cadmium (in utero) exposure with the ability to balance in children aged 7 and 10 years. DESIGN: Prospective birth cohort study. PARTICIPANTS: Maternal blood lead (n=4285) and cadmium (n=4286) levels were measured by inductively coupled plasma mass spectrometry in women enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) during pregnancy. Child lead levels were measured in a subsample of 582 of ALSPAC children at age 30 months. MAIN OUTCOME MEASURES: Children completed a heel-to-toe walking test at 7 years. At 10 years, the children underwent clinical tests of static and dynamic balance. Statistical analysis using SPSS V.19 included logistic regression modelling, comparing categories of ≥ 5 vs <5 µg/dL for lead, and ≥ 1 vs <1 µg/L for cadmium. RESULTS: Balance at age 7 years was not associated with elevated in utero lead or cadmium exposure (adjusted OR for balance dysfunction: Pb 1.01 (95% CI 0.95 to 1.01), n=1732; Cd 0.95 (0.77 to 1.20), n=1734), or with elevated child blood lead level at age 30 months (adjusted OR 0.98 (0.92 to 1.05), n=354). Similarly, neither measures of static nor dynamic balance at age 10 years were associated with in utero lead or cadmium exposure, or child lead level. CONCLUSIONS: These findings do not provide any evidence of an association of prenatal exposure to lead or cadmium, or lead levels in childhood, on balance ability in children. Confirmation in other cohorts is needed.

OBJECTIVE: To investigate the association of prenatal alcohol exposure with balance in10-year-old children. DESIGN: Population-based prospective longitudinal study. SETTING: Former Avon region of UK (Southwest England). PARTICIPANTS: 6915 children from the Avon Longitudinal Study of Parents and Children who had a balance assessment at age 10 and had data on maternal alcohol consumption. OUTCOME MEASURES: 3 composite balance scores: dynamic balance (beam-walking), static balance eyes open, static balance eyes closed (heel-to-toe balance on a beam and standing on one leg, eyes open or closed). RESULTS: Most mothers (95.5%) consumed no-to-moderate amounts (3-7 glasses/week) of alcohol during pregnancy. Higher total-alcohol consumption was associated with maternal-social advantage, whereas binge drinking (≥4 units/day) and abstinence were associated with maternal social disadvantage. No evidence was found of an adverse effect of maternal-alcohol consumption on childhood balance. Higher maternal-alcohol use during pregnancy was generally associated with better offspring outcomes, with some specific effects appearing strong (static balance eyes open and moderate total alcohol exposure at 18 weeks, adjusted OR 1.23 (95% CI 1.01 to 1.49); static balance eyes closed and moderate total alcohol exposure at 18 weeks, adjusted OR 1.25 (95% CI 1.06 to 1.48). Similar results were found for both paternal and postnatal maternal alcohol exposure. A Mendelian-randomization approach was used to estimate the association between maternal genotype and offspring balance using the non-synonymous variant rs1229984*A (ADH1B) to proxy for lower maternal alcohol consumption; no strong associations were found between this genotype/proxy and offspring balance. CONCLUSIONS: No evidence was found to indicate that moderate maternal alcohol consumption in this population sample had an adverse effect on offspring balance at age 10. An apparent beneficial effect of higher total maternal alcohol consumption on offspring balance appeared likely to reflect residual confounding.

Cardiovascular disease is one of the leading causes of death around the world. Resting heart rate has been shown to be a strong and independent risk marker for adverse cardiovascular events and mortality, and yet its role as a predictor of risk is somewhat overlooked in clinical practice. With the aim of highlighting its prognostic value, the role of resting heart rate as a risk marker for death and other adverse outcomes was further examined in a number of different patient populations. A systematic review of studies that previously assessed the prognostic value of resting heart rate for mortality and other adverse cardiovascular outcomes was presented. New analyses of nine clinical trials were carried out. Both the original and extended Cox model that allows for analysis of time-dependent covariates were used to evaluate and compare the predictive value of baseline and time-updated heart rate measurements for adverse outcomes in the CAPRICORN, EUROPA, PROSPER, PERFORM, BEAUTIFUL and SHIFT populations. Pooled individual patient meta-analyses of the CAPRICORN, EPHESUS, OPTIMAAL and VALIANT trials, and the BEAUTIFUL and SHIFT trials, were also performed. The discrimination and calibration of the models applied were evaluated using Harrell’s C-statistic and likelihood ratio tests, respectively. Finally, following on from the systematic review, meta-analyses of the relation between baseline and time-updated heart rate, and the risk of death from any cause and from cardiovascular causes, were conducted. Both elevated baseline and time-updated resting heart rates were found to be associated with an increase in the risk of mortality and other adverse cardiovascular events in all of the populations analysed. In some cases, elevated time-updated heart rate was associated with risk of events where baseline heart rate was not. Time-updated heart rate also contributed additional information about the risk of certain events despite knowledge of baseline heart rate or previous heart rate measurements. The addition of resting heart rate to the models where resting heart rate was found to be associated with risk of outcome improved both discrimination and calibration, and in general, the models including time-updated heart rate along with baseline or the previous heart rate measurement had the highest and similar C-statistics, and thus the greatest discriminative ability. The meta-analyses demonstrated that a 5bpm higher baseline heart rate was associated with a 7.9% and an 8.0% increase in the risk of all-cause and cardiovascular death, respectively (both p less than 0.001). Additionally, a 5bpm higher time-updated heart rate (adjusted for baseline heart rate in eight of the ten studies included in the analyses) was associated with a 12.8% (p less than 0.001) and a 10.9% (p less than 0.001) increase in the risk of all-cause and cardiovascular death, respectively. These findings may motivate health care professionals to routinely assess resting heart rate in order to identify individuals at a higher risk of adverse events. The fact that the addition of time-updated resting heart rate improved the discrimination and calibration of models for certain outcomes, even if only modestly, strengthens the case that it be added to traditional risk models. The findings, however, are of particular importance, and have greater implications for the clinical management of patients with pre-existing disease. An elevated, or increasing heart rate over time could be used as a tool, potentially alongside other established risk scores, to help doctors identify patient deterioration or those at higher risk, who might benefit from more intensive monitoring or treatment re-evaluation. Further exploration of the role of continuous recording of resting heart rate, say, when patients are at home, would be informative. In addition, investigation into the cost-effectiveness and optimal frequency of resting heart rate measurement is required. One of the most vital areas for future research is the definition of an objective cut-off value for the definition of a high resting heart rate.

Objetivo: Identificar factores sociodemográficos y de fecundidad, asociados a ocurrencia de embarazo no deseado en mujeres colombianas en edad reproductiva en el año 2010. Métodos: Se realizó estudio retrospectivo de corte transversal, basado en los datos de la ENDS Colombia-2010, del total de mujeres en edad fértil (13-49 años) que al momento de la encuesta se encontraban en embarazo. La variable de interés fue embarazo no deseado, se describió la población a estudio y se evaluó la posible asociación con variables sociodemográficas y de fecundidad, a través de análisis bivariado y multivariado. Se realizaron los mismos análisis por grupo de edad (adolescentes vs adultas). Resultados: La prevalencia de embarazo no deseado en las mujeres colombianas en el 2010 fue de 61,4 %. De acuerdo al modelo de regresión logística, no estar en unión a una pareja (OR: 4,01 IC95%: 3,066-5,269), tener hijos (OR: 2,040 IC95%: 1,581 – 2,631), estar en el quintil de menor riqueza (OR: 2,137 IC95%: 1,328-3,440), y ser adolescente (OR: 1,599 IC95%: 1,183-2,162), son factores que aumentan la probabilidad de tener un embarazo no deseado. Se encontraron diferencias en los factores asociados al realizar segmentación por edad. Conclusiones: La prevalencia de embarazo no deseado permanece alta en Colombia respecto a años anteriores y a otros países. Los resultados pueden ser de utilidad para el desarrollo de políticas en salud sexual y reproductiva teniendo en cuenta los factores asociados identificados priorizando a la población adolescente y de menor estatus socioeconómico, para la prevención de embarazo no deseado en Colombia.

La asfixia perinatal es la principal causa de muerte en la primera semana de vida la nivel mundial, los niños que sufren esta complicación y sobreviven pueden presentar trastornos neurológicos de diferente nivel de compromiso que inciden en su desarrollo personal y social. Las cifras de muerte por este problema de salud han disminuido de manera importante, sin embargo en el reporte de la Organización Mundial de Salud (OPS) del 2010, la asfixia perinatal es causa del 29% de muertes infantiles en los países de América Latina y el Caribe 2. Es necesario conocer además la extensión del daño neurológico que sufren estos niños, con este fin se desarrolló un estudio piloto en el Hospital Universitario Mayor Mederi de Bogotá, en el cual se determinó la concentración de un marcador metabólico de daño cerebral, la proteína S100B en suero de 60 recién nacidos sanos, con el objetivo de analizar la asociación del mismo con el peso al nacer, la edad gestacional y el diagnóstico. Los resultados no mostraron diferencias significativas entre este marcador y las variables analizadas que puede asociarse al pequeño número de pacientes, sin embargo han sentado las bases para el desarrollo de un estudio que incluya varios hospitales de Bogotá y sobre todo la determinación del mismo en recién nacidos con diagnóstico de hipoxia en el período perinatal, lo cual aportará información del grado de la alteración que puedan tener a nivel cerebral y contribuya al mejor manejo evolutivo con la aplicación de medidas de intervención en estadios tempranos de la vida.

Glyphosate-based herbicides (GBHs) are the most globally used herbicides raising the risk of environmental exposition. Carcinogenic effects are only one component of the multiple adverse health effects of Glyphosate and GBHs that have been reported. Questions related to hazards and corresponding risks identified in relation to endocrine disrupting effects are rising. The present study investigated the possible reproductive/developmental toxicity of GBHs administered to male and female Sprague-Dawley rats under various calendar of treatment. Assessments included maternal and reproductive outcome of F0 and F1 dams exposed to GBHs throughout pregnancy and lactation and developmental landmarks and sexual characteristics of offspring. The study was designed in two stages. In the first stage Glyphosate, or its commercial formulation Roundup Bioflow, was administered to rats at the dose of 1.75 mg/kg bw/day (Glyphosate US Acceptable Daily Intake) from the prenatal period until adulthood. In the second stage, multiple toxicological parameters were simultaneously assessed, including multigeneration reproductive/developmental toxicity of Glyphosate and two GBHs (Roundup Bioflow and Ranger Pro). Man-equivalent doses, beginning from 0.5 mg/kg bw/day (ADI Europe) up to 50 mg/kg bw/day (NOAEL Glyphosate), were administered to male and female rats, covering specific windows of biological susceptibility. The results of stage 1 and preliminary data from stage 2 experiments characterize GBHs as probable endocrine disruptors as suggested by: 1) androgen-like effects of Roundup Bioflow, including a significant increase of anogenital distances in both males and females, delay of first estrous and increased testosterone in females; 2) slight puberty onset anticipation in the high dose of Ranger Pro group, observed in the F1 generation treated from in utero life until adulthood; 3) a delayed balano-preputial separation achievement in the high dose of Ranger Pro-treated males exposed only during the peri-pubertal period, indicating a direct and specific effect of GBHs depending on the timing of exposure.

Introduction The maternal vasculature undergoes significant adaptations during pregnancy to meet the increased metabolic demands of the developing fetus. These adaptations include increased cardiac output and blood volume, as well as reduced systemic vascular resistance. In Hypertensive disorders of pregnancy (HDP) there is an impaired cardiovascular adaptation to pregnancy with effects extending beyond pregnancy. In the present study we aimed to characterize long-term cardiovascular status of women who suffered from HDP. Methods Fifty-eight women who attended at least one post-partum visit and a follow-up visit after at least 5 years from delivery were enrolled in the study. Exclusion criteria included multiple pregnancy, fetal genetic or congenital abnormalities, maternal history of organ transplantation, or chronic renal failure (eGFR≤45ml/min/1.73m2). In the follow-up visit participants underwent a complete cardiovascular assessment including echocardiography and multiparametric vascular function assessment. Results and Discussion Two major cardiovascular events, one stroke and one myocardial infarction, occurred both in women with index-pregnancy complicated by preeclampsia (PE). While not statistically significant, women with HDP-non-PE and PE displayed a trend towards an increased risk of developing composite cardiovascular outcome, and women with PE tended to experience it sooner. Nearly half of the women with a history of HDP, whether PE or HDP-non-PE, developed chronic hypertension. Some women also developed hyperuricemia, chronic kidney disease (CKD), and type 2 diabetes at follow- up, most of them had a previous history of PE. Structural and functional cardiac changes were observed in a few cases, especially among women with PE, and vascular dysfunction was more common in women with a history of HDP compared to those with normotensive pregnancies. Results of the present study adds on literature on long-term cardiovascular impact of HDP and further emphasize the importance of a timely follow-up of women who suffered from HDP and particularly PE.

Introduzione: La presentazione podalica complica il 3-4% delle gravidanze singole a termine. Sebbene il parto vaginale sia possibile, gli studi in letteratura hanno riportato un aumento del rischio di mortalità e morbilità fetale. Di conseguenza nel mondo il numero di tagli cesarei eseguiti per presentazione podalica è alto. Il rivolgimento per manovre esterne (RME) è una procedura ostetrica sicura che permette il passaggio del feto dalla presentazione podalica a quella cefalica, riducendo il numero dei tagli cesarei. L’angolo di progressione della parte presentata (AoP) è un parametro ecografico descritto in letteratura per la valutazione della progressione della parte presentata attraverso il canale del parto ed è stato recentemente studiato nelle gravidanze con presentazione podalica del feto. Obiettivi: L’obiettivo primario è valutare la correlazione tra l’AoP e il successo del RME. L’obiettivo secondario è verificare se esiste correlazione tra parametri anamnestici ed ecografici e la riuscita del RME. Materiali e metodi: È stato condotto uno studio osservazione prospettico monocentrico, sono state reclutate previo consenso informato 54 pazienti afferenti presso l’Ospedale Maggiore di Bologna con gravidanza singola dopo le 36 settimane e feto in presentazione podalica tra gennaio 2020 e giugno 2023. Risultati: La percentuale di RME riusciti è stata del 48,2%, il 53,7% delle donne ha partorito mediante taglio cesareo. Non abbiamo trovato una correlazione tra AoP e successo del rivolgimento. Tra le altre variabili analizzate l’unica correlata al successo del RME è la quantità di liquido amniotico Conclusioni: Non abbiamo trovato una correlazione tra AOP e successo del RME. Come descritto in letteratura l’unico parametro ecografico che è risultato associato al successo del RME è la quantità di liquido amniotico. Dato il disegno dello studio e la scarsa numerosità del campione sono necessari ulteriori studi per confermare i risultati.

Background. Benign prostatic hyperplasia (BPH) pharmacological treatment may promote a decrease in prostate vascularization and bladder neck relaxation with theoretical improvement in prostate biopsy morbidity, though never explored in the literature. Methods. Among 242 consecutive unselected patients who underwent prostate biopsy, after excluding those with history of prostate biopsy/surgery or using medications not for BPH, we studied 190 patients. On the 15th day after procedure patients were questioned about symptoms lasting over a week and classified according to pharmacological BPH treatment. Results. Thirty-three patients (17%) were using alpha-blocker exclusively, five (3%) 5-alpha-reductase inhibitor exclusively, twelve (6%) patients used both medications, and 140 (74%) patients used none. There was no difference in regard to age among groups (P = 0.5). Postbiopsy adverse effects occurred as follows: hematuria 96 (50%), hematospermia 53 (28%), hematochezia 22 (12%), urethrorrhagia 19 (10%), fever 5 (3%), and pain 20 (10%). There was a significant negative correlation between postbiopsy hematuria and BPH pharmacological treatment with stronger correlation for combined use of 5-alpha-reductase inhibitor and alpha-blocker over 6 months (P = 0.0027). Conclusion. BPH pharmacological treatment, mainly combined for at least 6 months seems to protect against prostate biopsy adverse effects. Future studies are necessary to confirm our novel results.

The vast majority of maternal deaths in low-and middle-income countries are preventable. Delay in obtaining access to appropriate health care is a fairly common problem which can be improved. The objective of this study was to explore the association between delay in providing obstetric health care and severe maternal morbidity/death. This was a multicentre cross-sectional study, involving 27 referral obstetric facilities in all Brazilian regions between 2009 and 2010. All women admitted to the hospital with a pregnancy-related cause were screened, searching for potentially life-threatening conditions (PLTC), maternal death (MD) and maternal near-miss (MNM) cases, according to the WHO criteria. Data on delays were collected by medical chart review and interview with the medical staff. The prevalence of the three different types of delays was estimated according to the level of care and outcome of the complication. For factors associated with any delay, the PR and 95%CI controlled for cluster design were estimated. A total of 82,144 live births were screened, with 9,555 PLTC, MNM or MD cases prospectively identified. Overall, any type of delay was observed in 53.8% of cases; delay related to user factors was observed in 10.2%, 34.6% of delays were related to health service accessibility and 25.7% were related to quality of medical care. The occurrence of any delay was associated with increasing severity of maternal outcome: 52% in PLTC, 68.4% in MNM and 84.1% in MD. Although this was not a population-based study and the results could not be generalized, there was a very clear and significant association between frequency of delay and severity of outcome, suggesting that timely and proper management are related to survival.

Bisphenol-A (BPA) is one of the most widespread EDCs used as a base compound in the manufacture of polycarbonate plastics. The aim of our research has been to study how the exposure to BPA during pregnancy affects weight, glucose homeostasis, pancreatic β-cell function and gene expression in the major peripheral organs that control energy flux: white adipose tissue (WAT), the liver and skeletal muscle, in male offspring 17 and 28 weeks old. Pregnant mice were treated with a subcutaneous injection of 10 µg/kg/day of BPA or a vehicle from day 9 to 16 of pregnancy. One month old offspring were divided into four different groups: vehicle treated mice that ate a normal chow diet (Control group); BPA treated mice that also ate a normal chow diet (BPA); vehicle treated animals that had a high fat diet (HFD) and BPA treated animals that were fed HFD (HFD-BPA). The BPA group started to gain weight at 18 weeks old and caught up to the HFD group before week 28. The BPA group as well as the HFD and HFD-BPA ones presented fasting hyperglycemia, glucose intolerance and high levels of non-esterified fatty acids (NEFA) in plasma compared with the Control one. Glucose stimulated insulin release was disrupted, particularly in the HFD-BPA group. In WAT, the mRNA expression of the genes involved in fatty acid metabolism, Srebpc1, Pparα and Cpt1β was decreased by BPA to the same extent as with the HFD treatment. BPA treatment upregulated Pparγ and Prkaa1 genes in the liver; yet it diminished the expression of Cd36. Hepatic triglyceride levels were increased in all groups compared to control. In conclusion, male offspring from BPA-treated mothers presented symptoms of diabesity. This term refers to a form of diabetes which typically develops in later life and is associated with obesity.
