Effects of SARS-COVID-19 lockdown on menstrual patterns: A transversal large sample survey.

OBJECTIVE: To elucidate the presence, importance, and characteristics of menstrual changes related to stressful circumstances during the COVID-19 lockdown in Spain. STUDY DESIGN: An online survey was administered in Spain to menstruating women aged 15-55 who had not contracted COVID-19. It collected information on activities during the lockdown, sexual activity, perceptions of emotional status, any changes in menstrual characteristics, and impact on quality of life. The analysis of menstrual changes was limited to responders who did not use hormonal contraception. RESULTS: A total of 6449 women answered the survey, and 4989 surveys were valid for the final analysis. 92.3% of women had at least one menstruation period during the lockdown, while 7.7% had amenorrhea. Quality of life (QoL) associated with menstruation worsened in 19% of women, did not change in 71.7%, and improved in 1.6%. For 50.1% of the women, global QoL worsened during the lockdown; 41.3% remained about the same and 8.7% reported improvement. Sexual activity during the lockdown decreased in 49.8% of the respondents, remained unchanged in 40.7%, and increased in 9.5%. As far the menstrual changes are concerned, there were no statistically significant differences in amenorrhea incidence, regularity of the menstrual cycle, or the amount or duration of menstrual bleeding in non-hormonal contraceptive users when evaluated by the length and characteristics of isolation, the perception of exposure to COVID-19 and the economic or employment situation. Conversely, we found statistically significant differences according to the intensity of changes in emotional status due to lockdown stressors and changes in regularity, duration, and heaviness of menstruation. CONCLUSION: Changes in emotional status, but not the length and intensity of the isolation or exposure to the disease, significantly influenced menstrual disturbances during the COVID-19 lockdown.

Health-related quality of life and satisfaction associated with 3-year use of a levonorgestrel 13.5 mg intrauterine device vs Nova T copper 380 mm2 intrauterine device: Results of a phase 4 randomized controlled trial.

OBJECTIVES: This study aimed to investigate the impact of levonorgestrel 13.5 mg and Nova T copper 380 mm2 intrauterine devices (LNG13.5-IUD and Cu380-IUD, respectively) on health-related quality of life (HRQoL) and the satisfaction with the method throughout 3 years of use. STUDY DESIGN: We conducted a single-center, evaluator-masked, randomized controlled trial to compare the bleeding profile of LNG13.5-IUD and Cu380-IUD users. Secondary objectives included HRQoL and satisfaction throughout the study. We used the validated questionnaire of the Spanish Society of Contraception (SEC-QoL), which evaluates social, sexual/psychological well-being, and menstrual/breast symptoms, to assess HRQoL and a 5-point Likert scale for satisfaction. RESULTS: These secondary outcomes were assessed in the whole population included in the study: 55 LNG13.5-IUD and 51 Cu380-IUD users. The mean overall SEC-QoL scores were similar at baseline (61.5 and 59.6, respectively; p = 0.570) and greater for LNG13.5-IUD after 3 years (69.2 vs 52.5, respectively; p = 0.002). All SEC-QoL domains scored also higher (p < 0.05 vs Cu380-IUD for all). At month 36, 20/30 (67%) and 8/28 (29%) users, respectively, had reached the MID (a 3.4-point increase) in SEC-QoL score (p = 0.004). At this time, 24/29 (82%) and 9/28 (32%) users, respectively, were "very satisfied" (p < 0.001). Willingness to continue the method was similar (22/28 [79%] vs 17/28 [61%] users, respectively; p = 0.170). CONCLUSIONS: Among the use of LNG13.5-IUD was associated with better HRQoL vs Cu380-IUD throughout the 3 years. Satisfaction with the method was higher with LNG13.5-IUD. IMPLICATIONS: People considering having an LNG13.5-IUD or a Cu380-IUD inserted may now benefit from the information regarding the impact of these devices on HRQoL and satisfaction with the method as reported in our study conducted in Spain.

High prevalence of venous thrombotic events in Cushing's syndrome: data from ERCUSYN and details in relation to surgery.

OBJECTIVE: The aim of this study was to evaluate the prevalence of venous thromboembolism (VTE) in patients included in the European Registry on Cushing's syndrome (ERCUSYN), compare their clinical characteristics with those who did not develop VTE and identify risk factors for VTE. DESIGN: A retrospective observational cohort study. METHODS: Data extraction from the registry was taken on February, 7, 2022. At the time there were 2174 patients diagnosed with Cushing's syndrome (CS) and 95 VTEs were reported in the database. RESULTS: Of 95 VTE events 70 (74%) were in pituitary-dependent CS patients, 12 (12.5%) in adrenal-dependant CS, 10 (10.5%) in ectopic CS, and 3 (3%) in CS due to other causes. Sex, 24-hour urinary free cortisol (UFC) value at diagnosis, as well as the number of operations remained statistically significant predictors of VTE. Of patients who were treated with at least one surgery, 12 (13%) VTE occurred before and 80 (87%) after the surgery. Nearly half of these VTEs occurred within six months since the operation (36; 45%). Over half of the centers that reported VTE did not routinely anticoagulate CS patients. Anticoagulation schemes varied widely. CONCLUSION: Patients with CS have an elevated risk of developing VTE for an extended period of time. From ERCUSYN cohort patients have higher risk for VTE if they need multiple surgeries to treat CS, are males and have high UFC values at the diagnosis of CS. Since there is no agreement on thromboprohpylaxis, a protocol for VTE prevention that is widely adopted appears to be necessary for patients with CS.

Bleeding profile and safety of a levonorgestrel 13.5 mg intrauterine device versus Nova T copper 380 mm2 intrauterine device: Results of a 3-year, single-center, randomized phase 4 study.

OBJECTIVE: To assess the bleeding profiles of the levonorgestrel 13.5 mg intrauterine device (LNG13.5-IUD) and Nova T copper 380 mm2 IUD (Cu380-IUD). STUDY DESIGN: Single-center, evaluator-masked, randomized study conducted in women aged 18-45 years starting these methods. Primary outcomes were number of bleeding days, self-reported bleeding intensity, Pictorial Blood Assessment Chart (PBAC) score, and blood biochemical values at baseline, months 3, 6, 12, 24, and 36 per 90-day reference periods except for PBAC (months). Secondary objectives were presence/duration/intensity of dysmenorrhea and tolerability. RESULTS: We included 106 women aged 32.5 ± 6.7 years: 55 with LNG13.5-IUD and 51 with Cu380-IUD. Data for LNG13.5-IUD versus Cu380-IUD at baseline and month 36 (both respectively) were as follows: (1) median (25th; 75th percentile) number of bleeding days: 12 (9.0; 15.0) versus 12 (9.0; 15.0), p = 0.82, and 4 (0; 13.7) versus 15 (14.2; 20.0), p < 0.001; (2) mean bleeding intensity: 1.7 for both, p = 0.66, and 0.7 and 2.2, p < 0.001. Forty percent versus 0% presented with amenorrhea at month 36; (3) mean PBAC score (95% Confidence interval (CI): 50.7 (16.6; 84.7) versus 130.4 (95.7; 165.0) at month 1, and 7.9 (-26.7; 42.6) versus 126 (90.7; 161.2), p < 0.001; (4) median (25th; 75th percentile) ferritin levels (Ug/L) 33 (19; 53) versus 30 (19; 45), p = 0.70, and 59 (42; 84) versus 21 (8; 39). We did not observe changes or differences between groups in hemoglobin and hematocrit. The duration and intensity of dysmenorrhea were significantly lower with LNG13.5-IUD versus Cu380-IUD. Adverse events were those expected. CONCLUSIONS: LNG13.5-IUD is associated with a significant reduction in blood loss and dysmenorrhea compared with Cu380-IUD. IMPLICATIONS: Women eligible for a levonorgestrel 13.5 mg intrauterine device (IUD) or a copper 380 mm2 IUD should be informed of the differences in bleeding profiles-one of the main causes for IUD discontinuation-so they can compare this information against their bleeding expectations.

Cost-effectiveness of a high-sensitivity cardiac troponin T systematic screening strategy compared with usual care to identify patients with peri-operative myocardial injury after major noncardiac surgery.

BACKGROUND: About 300 million surgeries are performed worldwide annually and this figure is increasing constantly. Peri-operative myocardial injury (PMI), detected by cardiac troponin (cTn) elevation, is a common cardiac complication of noncardiac surgery, strongly associated with short- and long-term mortality. Without systematic peri-operative cTn screening, most cases of PMI may go undetected. However, little is known about cost effectiveness of a systematic PMI screening strategy with high-sensitivity cardiac troponin T (hs-cTnT) after noncardiac surgery. OBJECTIVE: To assess, in patients with high cardiovascular risk, the cost-effectiveness of a systematic screening strategy using a hs-cTnT assay, to identify patients with PMI after major noncardiac surgery, compared with usual care. DESIGN: Cost-effectiveness analysis; single centre prospective cohort study. SETTING: Spanish University Hospital. PATIENTS: From July 2016 to March 2019, we included 1477 consecutive surgical patients aged ≥65 or if <65, with documented history of cardiovascular disease or impaired renal function, who underwent major noncardiac surgery and required at least an overnight hospital stay. We excluded patients aged <65 years without cardiovascular disease, undergoing minor surgery, or with an expected <24 h hospital stays. INTERVENTIONS: We conducted a decision-tree analysis, comparing a systematic screening strategy measuring hs-cTnT before surgery, and at the 2nd and 3rd days after surgery vs. a usual care strategy. We considered a third-party payer perspective and the outcomes of both strategies in the short-term (30 days follow-up). Information about costs was expressed in Euros-2021. We calculated the incremental cost-effectiveness ratio (ICER) of the systematic hs-cTnT strategy, defined as the expected cost per any additional PMI detected, and explored the robustness of the model using deterministic and probabilistic sensitivity analysis. MAIN OUTCOME MEASURES: ICER of the systematic hs-cTnT screening strategy. RESULTS: The ICER was €425 per any additionally detected PMI. The deterministic sensitivity analysis showed that a 15% variation in costs, and a 1% variation in the predictive values, had a minor impact over the ICER, except in case of the negative predictive value of the systematic hs-cTnT screening strategy. Monte Carlo simulations (probabilistic sensitivity analysis) showed that systematic hs-cTnT screening would be cost-effective in 100% of cases with a 'willingness to pay' of €780. CONCLUSIONS: Our results suggest that systematic peri-operative PMI screening with hs-cTnT may be cost-effective in the short-term in patients undergoing major noncardiac surgery. Economic evaluations, with a long-term horizon, are still needed. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03438448.

Effectiveness of Nurse-Led Preoperative Assessment for Anesthesia: A Prospective Cohort Study.

PURPOSE: This study aimed to evaluate, in low-complexity surgical patients, the effectiveness of preoperative assessment carried out by nurses with formal postgraduate anesthetic training compared to that carried out by anesthesiologists in terms of cancellations and inadequate surgical preparation. DESIGN: This experimental research was conducted using a prospective cohort study. METHODS: One hundred and eighty-three patients were recruited who had undergone low-complexity surgery between May and September 2020. Sixty-nine patients were preoperatively assessed by a nurse with specific 1-year postgraduate university training in anesthesia and 114 by an anesthesiologist. Data collection included a questionnaire to assess patient satisfaction and knowledge acquired from the preoperative assessment. FINDINGS: Cancellations of surgery were the same in both cohorts (3.8%, 2.6%). The incidence of poor preparation attributable to the patient was also similar in both cohorts (17.0% vs 18.4%). Patients seen by nurses valued the satisfaction with the preoperative assessment more highly than patients seen by anesthesiologists (median 91.67 vs 84.62). In terms of Knowledge obtained from the preoperative assessment, both professionals did not show statistically significant differences in knowledge levels. CONCLUSIONS: Preoperative patient assessment performed by a nurse, with formal anesthesia training, in low-complexity surgical patients can be as effective as that performed by an anesthesiologist, without having an impact on surgical cancellations or patient preparation. On the day of surgery, patients who had been assessed by a nurse were more satisfied with their care during the visit and acquired similar knowledge about preoperative preparation as patients assessed by anesthesiologists.

Are antihistamines still used during omalizumab treatment for chronic spontaneous urticaria?

Background: The guidelines for the treatment of chronic spontaneous urticaria (CSU) recommend adding omalizumab to the treatment of patients with uncontrolled disease despite four-fold doses of second-generation antihistamines (AH). On the contrary, some studies revealed that omalizumab was effective without concomitant AH and several authors suggest tapering off AH when CSU is controlled with omalizumab. Objectives: The aim of our study was to evaluate the use of AH during treatment with omalizumab in patients with CSU in real clinical practice. Materials & Methods: This was a multicentre cross-sectional and observational study conducted by the Catalan and Balearic Chronic Urticaria Network (XUrCB) based on a cohort of 298 CSU patients treated with omalizumab. Results: In total, 23.5% of our patients decided themselves to stop taking AH during omalizumab treatment. The ratio of patients with CSU without concomitant inducible urticaria and the percentage of patients with a good response to omalizumab (UAS7≤6 and/or UCT ≥12) were higher in those who stopped taking AH. Conclusion: More studies are required to identify the phenotypic characteristics of patients responding to omalizumab as monotherapy in order to avoid overtreating with AH. Our study suggests that patients with CSU without concomitant inducible urticaria and those who achieve a good response to omalizumab tend to be controlled by omalizumab without AH. In order to establish guidelines on how to stop AH, further evidenced-based studies are required.

Influencia de las comorbilidades en la intensidad del dolor en los pacientes con lumbalgia crónica / Influence of comorbidities on pain intensity in patients with chronic low back pain

ObjetivoEl dolor crónico es un proceso complejo que puede variar dependiendo de factores como el tiempo de evolución, estado de ánimo o incluso experiencias previas vividas. Nuestro objetivo es describir las características de los pacientes que acuden con diagnóstico de lumbalgia a una primera visita en la Unidad del Dolor (UD) y buscar aquellos factores que pueden interferir en la percepción del dolor.MétodosSe realiza un análisis inferencial de los pacientes que acuden por primera vez a la UD del Hospital de la Santa Creu y Sant Pau de Barcelona con diagnóstico de lumbalgia crónica durante el periodo de Noviembre 2012 a Noviembre 2018. La intensidad del dolor promedio en las últimas 24 horas se cuantifica utilizando datos del cuestionario Brief Pain Inventory (BPI). Utilizando regresión linear múltiple, se valoran los factores predictivos independientes de intensidad de dolor EVN24.ResultadosLa variable de mayor impacto fue el grado de depresión según HAD_D. Utilizando regresión logística binaria para el análisis multivariado, se obtuvo un modelo que se relaciona (r = 0,354, p < 0,001) de manera significativa con la intensidad del dolor (EVN24).ConclusionesEl tratamiento especializado de la lumbalgia en las UD debe tener en cuenta el perfil de paciente y en especial los trastornos afectivos y las comorbilidades asociadas ya que predicen una mayor intensidad del dolor. En consecuencia, la comorbilidad asociada no solo repercute en la mayor intensidad del dolor, sino que las características físicas que acompañan al paciente durante todo el proceso pueden influir o incluso comprometer el tratamiento.

ObjectivesChronic pain is a complex process that can vary depending on factors such as time evolution, mood, or even previous experiences. Our objective is to describe patient's characteristics from those who were referred with a diagnosis of low back pain in their first Pain Unit (PU) visit, and identify those factors that may interfere with their pain perception.MethodsInferential analysis was carried out from data recorded in the PU database of the Hospital de la Santa Creu y Sant Pau in Barcelona, from November 2012 to November 2018. The average pain intensity during the last 24 hours (EVN24) was quantified using data from the BPI (Brief Pain Inventory) questionnaire. Using multiple linear regression, the independent predictive factors related to pain intensity (EVN24) were assessed.ResultsMood disorders (Degree of depresión acording HAD_D level) was the variable with the highest impact in pain perception. Using binary logistic regression for multivariate analysis, a model of variables related to pain intensity (EVN24) was obtained (R = 0.354, P < 0.001).ConclusionsThe specialized treatment of low back pain in PUs must take into account the patient's profile and especially the affective disorders and associated comorbidities since they predict a greater intensity of pain. Consequently, the associated comorbidity not only affects the greater intensity of pain, but the physical characteristics that accompany the patient throughout the process can influence or even compromise treatment.

What do female university students know about pelvic floor disorders? A cross-sectional survey.

INTRODUCTION AND HYPOTHESIS: Pelvic floor dysfunction (PFD) is common in women but few seek medical attention. Poor recognition of the condition as pathological and unawareness of treatments may account for low consultation rates. METHODS: This cross-sectional study was based on an online survey that was responded to in February and March 2020 by 768 female university students. Knowledge of PFD was assessed using the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). Descriptive and inferential analyses were performed using IBM-SPSS (V26.0). RESULTS: Respondents had poor knowledge of PFD and especially of pelvic organ prolapse. Health science students (n = 531; 69.1%) obtained significantly higher scores (p < 0.001) than other students (n = 237; 30.9%). Those who had received information on how to perform pelvic floor muscle training were more likely to score higher than those who had not received previous information. CONCLUSIONS: While health science students have better knowledge of PFD than other students, university students in general are little aware of PFD. Most students considered the issue of PFD to be important and wanted more information. Our findings may be useful in planning strategies to raise women's awareness of PFD and its prevention and treatment.

Vitamin D recommendations in clinical guidelines: A systematic review, quality evaluation and analysis of potential predictors.

BACKGROUND: Vitamin D has been widely promoted for bone health through supplementation and fortification of the general adult population. However, there is growing evidence that does not support these strategies. Our aim is to review the quality and recommendations on vitamin D nutritional and clinical practice guidelines and to explore predictive factors for their direction and strength. METHODS: We searched three databases and two guideline repositories from 2010 onwards. We performed a descriptive analysis, a quality appraisal using AGREE II scores (Appraisal of Guidelines Research and Evaluation) and a bivariate analysis evaluating the association between direction and strength of recommendations, AGREE II domains' scores and pre-specified characteristics. RESULTS: We included 34 guidelines, 44.1% recommended, 26.5% suggested and 29.4% did not recommend vitamin D supplementation. Guidelines that scored higher for "editorial independence" and "overall quality score" were less likely to recommend or suggest vitamin D supplementation (median 68.8 vs 35.4; P = .001 and 58.3 vs 37.5; P = .02). Guidance produced by government organisations and those that reported source of funding were associated with higher AGREE II scores. Unclear role of source of funding was associated with recommending or suggesting vitamin D supplementation (P = .034). Editorial independence was an independent predictor for recommending or suggesting vitamin D supplementation (OR 1.09; CI95% 1.02 to 1.16; P = .006). CONCLUSIONS: Policymakers, clinicians and patients should be aware that lower quality guidelines and those reporting conflicts of interest are more likely to promote vitamin D supplementation. Guideline organisations should improve the quality of their recommendations' development and the management of conflicts of interest. Users and editors should be aware of these findings when using and appraising guidelines.

Use of delayed antibiotic prescription in primary care: a cross-sectional study.

BACKGROUND: One of several strategies developed to reduce inappropriate antibiotic use in situations where the indication is not clear is delayed antibiotic prescription (DAP), defined as an antibiotic prescription issued for the patient to take only in case of feeling worse or not feeling better several days after the visit. We conducted a survey to identify DAP use in Spanish primary care settings. METHODS: We surveyed 23 healthcare centers located in 4 autonomous regions where a randomized controlled trial (RCT) on DAP was underway. The primary variable was use of DAP. Categorical and quantitative variables were analyzed by means of the chi-squared test and non-parametric tests, respectively. RESULTS: The survey was sent to 375 healthcare professionals, 215 of whom responded (57.3% response rate), with 46% of these respondents declaring that they had used DAP in routine practice before the RCT started (66.6% afterwards), mostly (91.5%) for respiratory tract infections (RTIs), followed by urinary infections (45.1%). Regarding DAP use for RTIs, the most frequent conditions were pharyngotonsillitis (88.7%), acute bronchitis (62.7%), mild chronic obstructive pulmonary disease exacerbations (59.9%), sinusitis (51.4%), and acute otitis media (45.1%). Most respondents considered that DAP reduced emergency visits (85.4%), scheduled visits (79%) and inappropriate antibiotic use (73.7%) and most also perceived patients to be generally satisfied with the DAP approach (75.6%). Having participated or not in the DAP RCT (74.1% versus 46.2%; p < 0.001), having previously used or not used DAP (86.8% versus 44.2%; p < 0.001), and being a physician versus being a nurse (81.8% versus 18.2%; p < 0.001) were factors that reflected significantly higher rates of DAP use. CONCLUSIONS: The majority of primary healthcare professionals in Spain do not use DAP. Those who use DAP believe that it reduces primary care visits and inappropriate antibiotic use, while maintaining patient satisfaction. Given the limited use of DAP in our setting, and given that its use is mainly limited to RTIs, DAP has considerable potential in terms of its implementation in routine practice.

[Mortality in Colombia traffic accidents. Comparative study with other countries]. / Mortalidad por accidentes de tráfico en Colombia. Estudio comparativo con otros países.

OBJECTIVE: Traffic accidents (TA) are a global problem with mortality of 1.25 million each year. The objective of this study was to compare adjusted mortality rates (AMR) by AT of Colombia, with Spain and the United States (US). The selection is justified because Colombia is a country with less development in road safety, Spain a nation that has adhered to European guidelines and US for having little adherence to international guidelines. METHODS: A descriptive cross-sectional study was carried out for five-year periods, by calculating the AMRs by the direct method of standardization according to sex and age groups, as well as the adjustment of the motorization index. The mean values, the 95% confidence interval for each country and the relative change between the periods studied were calculated. RESULTS: The AMR of periods P1 and P2 in all countries decreased significantly (p <0.005). In periods P2 and P3 also decreased significantly in Spain, by 52.0% (p = 0.010), and in the US, by 23.6% p = 0.001), while in Colombia the difference of 4.0% it was not significant (p = 0.724). Spain stood out for the reduction in mortality (P1-P3), by 69.0%. CONCLUSIONS: Colombia presented a less favorable evolution of mortality due to AT than Spain and the US. Men aged 15 to 44, motorcyclists and cyclists were the most committed. The TAs are a public health problem that Colombia has raised and must adapt to its reality those successful measures in other countries.

OBJETIVO: Los accidentes de tráfico (AT) son un problema mundial con mortalidad de 1,25 millones cada año. El objetivo de este estudio fue comparar tasas ajustadas de mortalidad (TAM) por AT de Colombia, con España y Estados Unidos (EEUU). La selección se justifica por ser Colombia un país con menor desarrollo en seguridad vial, España una nación que se ha adherido a directrices Europeas y EEUU por tener poca adherencia a directrices internacionales. METODOS: Se realizó un estudio descriptivo de corte trans- versal por quinquenios, mediante el cálculo de las TAM por el método directo de estandarización según sexo y grupos de edad, así como el ajuste del índice de motorización. Se calcularon los valores medios, el intervalo de confianza al 95% por cada país y el cambio relativo entre los períodos estudiados. RESULTADOS: Las TAM de los períodos P1 y P2 en todos los países disminuyeron significativamente (p <0.005). En los períodos P2 y P3 también disminuyeron significativamente en España, en un 52,0% (p=0,010), y en EU, en un 23,6% p=0,001), mientras que en Colombia la diferencia de 4,0% no fue significativa (p=0,724). Destacó España por la reducción de su mortalidad (P1-P3), en un 69.0%. CONCLUSIONES: Colombia presentó una evolución menos favorable de mortalidad por AT que España y EEUU. Los hombres de 15 a 44 años, motociclistas y ciclistas fueron los más comprometidos. Los AT son un problema de salud pública que tiene planteado Colombia y debe adaptar a su realidad aquellas medidas exitosas en otros países.

Mode of vaginal delivery: a modifiable intrapartum risk factor for obstetric anal sphincter injury.

The aim of this study was to analyze the comparative risks of this anal sphincter injury in relation to the type of intervention in vaginal delivery. We performed an observational, retrospective study of all vaginal deliveries attended at a tertiary university hospital between January 2006 and December 2009. We analyzed the incidence of obstetric anal sphincter injury for each mode of vaginal delivery: spontaneous delivery, vacuum, Thierry spatulas, and forceps. We determined the proportional incidence between methods taking spontaneous delivery as the reference. Ninety-seven of 4526 (2.14%) women included in the study presented obstetric anal sphincter injury. Instrumental deliveries showed a significantly higher risk of anal sphincter injury (2.7 to 4.9%) than spontaneous deliveries (1.1%). The highest incidence was for Thierry spatulas (OR 4.804), followed by forceps (OR 4.089) and vacuum extraction (OR 2.509). The type of intervention in a vaginal delivery is a modifiable intrapartum risk factor for obstetric anal sphincter injury. Tearing can occur in any type of delivery but proportions vary significantly. All healthcare professionals attending childbirth should be aware of the risk for each type of intervention and consider these together with the obstetric factors in each case.

Survival in Mediterranean ambulatory patients with chronic heart failure. A population-based study.

INTRODUCTION AND OBJECTIVES: Scarce research has been performed in ambulatory patients with chronic heart failure in the Mediterranean area. Our aim was to describe survival trends in our target population and the impact of prognostic factors. METHODS: We carried out a population-based retrospective cohort study in Catalonia (north-east Spain) of 5659 ambulatory patients (60% women; mean age 77 [10] years) with incident chronic heart failure. Eligible patients were selected from the electronic patient records of primary care practices from 2005 and were followed-up until 2007. RESULTS: During the follow-up period deaths occurred in 950 patients (16.8%). Survival after the onset of chronic heart failure at 1, 2, and 3 years was 90%, 80%, 69%, respectively. No significant differences in survival were found between men and women (P=.13). Cox proportional hazard modelling confirmed an increased risk of death with older age (hazard ratio=1.06; 95% confidence interval, 1.06-1.07), diabetes mellitus (hazard ratio=1.53; 95% confidence interval, 1.33-1.76), chronic kidney disease (hazard ratio=1.73; 95% confidence interval, 1.45-2.05), and ischemic heart disease (hazard ratio=1.18; 95% confidence interval, 1.02-1.36). Hypertension (hazard ratio=0.73; 95% confidence interval, 0.64-0.84) had a protective effect. CONCLUSIONS: Service planning and prevention programs should take into consideration the relatively high survival rates found in our area and the effect of prognostic factors that can help to identify high risk patients.

Glycemic control and pregnancy outcomes in women with type 1 diabetes mellitus using lispro versus regular insulin: a systematic review and meta-analysis.

AIMS: This study performed a systematic review and meta-analysis on glycemic control and pregnancy outcomes in women with type 1 diabetes mellitus (T1DM) treated with lispro (LP) versus regular insulin (RI) since before pregnancy. METHODS: We performed a MEDLINE and EMBASE search. Abstracts (and full articles when appropriate) were reviewed by two independent researchers. Inclusion criteria were patients with T1DM, data on women treated with RI and LP since before pregnancy until delivery in the same article, at least five pregnancies in each group, and information on at least one pregnancy outcome. Quality assessment was performed using the Newcastle-Ottawa Quality Assessment Scale for cohort studies. RESULTS: Outcome data were summarized with Revman version 5.0 (ims.cochrane.org/revman/download [The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark]), applying a random effects model. Two hundred sixty-seven abstracts were identified, and four full articles fulfilled inclusion criteria, all of them corresponding to observational studies. Baseline characteristics were similar in women treated with LP or RI. Regarding outcome data, no differences between LP and RI groups were observed in hemoglobin A1c, gestational age at birth, birth weight, and rate of diabetic ketoacidosis, pregnancy-induced hypertension, pre-eclampsia, spontaneous miscarriages, interruptions, total abortions, cesarean section, preterm birth, macrosomia, small-for gestational-age newborns, stillbirth, neonatal and perinatal mortality, neonatal hypoglycemia, and major malformations. The rate of large-for-gestational age newborns was higher in the LP group (relative risk 1.38; 95% confidence interval 1.14-1.68). CONCLUSIONS: In relation to women with T1DM treated with RI, those treated with LP display similar baseline characteristics and no differences in metabolic control or perinatal outcome with the exception of a higher rate of large-for-gestational-age newborns.
