Breastfeeding is associated with a delayed decrease in postprandial maternal glucose concentration.

BACKGROUND: Breastfeeding has long-term benefits in reducing the risk of diabetes; however, information about the acute influence on maternal glucose profile is scarce. Thus, the aim of the study was to assess maternal glucose fluctuations associated with breastfeeding episodes in women with normal glucose status. METHODS: We performed an observational study of glucose fluctuations with breastfeeding episodes in 26 women with normal glucose status in fasting and postprandial state. Continuous glucose monitoring was performed using CGMS MiniMed Gold®/iPro2® (Medtronic, Dublin, Ireland) three months after delivery under real-life conditions. We compared fasting and postprandial periods of 150 minutes affected or not by a breastfeeding episode. RESULTS: Mean glucose concentration of postprandial periods affected by breastfeeding was lower than not affected (-6.31 mg/dL [95% CI: -11.17, -1.62] P<0.01). Glucose concentration was significantly lower between 50 and 105 minutes after meal initiation (maximum difference -9.19 mg/dL [95% CI: -16.03, -2.16] at 91-95 min). Mean glucose concentrations of fasting periods affected by breastfeeding were similar to those not affected (-0.18 mg/dL [95% CI: -2.7, 0] P=0.831). CONCLUSIONS: In women with normal glucose status, breastfeeding episodes are associated with a lower glucose concentration in the postprandial but not in the fasting state.

Breastfeeding effect on glucose tolerance assessment in women with previous gestational diabetes mellitus: A randomized controlled trial.

AIMS: To test whether breastfeeding during the oral glucose tolerance test (OGTT) affects glucose and insulin outcomes (main outcome: 120 min plasma glucose). METHODS: A randomized crossover trial was conducted in 20 women with prior gestational diabetes mellitus. Each woman undertook two OGTTs in the first 3 months after delivery, breastfeeding the infant in one and avoiding breastfeeding in the other. Glucose and insulin were measured at 0, 30, 60 and 120 min. Statistics included: T-test for paired data, general linear model (GLM) for repeated measures. Analysis of covariance (ANCOVA) was used to adjust for glucose and insulin values at 0 min. Statistical dispersion for GLM and ANCOVA outcomes is expressed as standard error. RESULTS: In the OGTTs with breastfeeding, higher values were observed for overall glucose and insulin concentrations, glucose and insulin peaks and individual time points of glucose (at 0, 30 and 60 min) and insulin (at 0 and 60 min) but without differences at 120 min (glucose 6.7 ± 0.3 vs. 6.9 ± 0.3 mmol/L, p = 0.506). The rate of abnormal tests was not different. ANCOVA confirmed higher postchallenge glucose values in the OGTT with breastfeeding and similar glucose values at 120 min. CONCLUSIONS: According to the results of this randomized trial, we conclude that breastfeeding during the OGTT resulted in similar 120 min glucose concentration and glycaemic status categorization. However, breastfeeding during the OGTT led to clear differences in glucose and insulin values in the first hour, that warrant further studies.

Interconsultas urológicas a un Servicio de Ética Clínica en un hospital de IV nivel / Urological Interconsultations to a Clinical Ethics Service in a Level-IV Hospital

Objetivo Los problemas éticos tienen una gran importancia en discusiones teóricas en la medicina, y este estudio tiene como objetivo caracterizar a los pacientes urológicos cuyos casos fueron motivos de consulta al Servicio de Ética Clínica (SEC) institucional de un hospital de IV nivel para comprender los dilemas éticos prevalentes en la práctica diaria de la urología y su abordaje. Materiales y Métodos Estudio descriptivo en el que se realizó una revisión retrospectiva de las historias clínicas de 20 pacientes urológicos interconsultados al SEC de un hospital de IV nivel. Se evaluó la frecuencia de las siguientes variables: diagnóstico, estadio funcional y clínico en el momento del diagnóstico, tiempo de evolución, tratamientos, y tipo de dilema ético motivo de la interconsulta. Resultados Desde enero de 2018, el SEC del Hospital Universitario San Ignacio ha respondido 1.123 interconsultas, y se vio un aumento significativo de las mismas en 2020 por razón de la pandemia de enfermedad por coronavirus 2019 (coronavirus disease 2019, COVID-19, en inglés). De estas interconsultas, solamente trece corresponden a pacientes con patología urológica de base, y siete, a compromiso urológico secundario. El diagnóstico más frecuente fue carcinoma de próstata en estadio IV, seguido de carcinoma urotelial avanzado. Predominó el tratamiento adecuado; solamente tres se diagnosticaron en ese momento, y no alcanzaron a recibir tratamiento. El principal dilema ético encontrado tuvo que ver con proporcionalidad al final de la vida, en dos casos, con respeto de la autonomía del paciente, incluida una solicitud de eutanasia. Conclusión El tamizaje establecido y los tratamientos efectivos tempranos se podrían reflejar en la baja frecuencia de situaciones clínicas extremas conducentes a la toma de decisiones al final de la vida, que serían dirigidas, entonces, ya sea a la reorientación del esfuerzo terapéutico, al plan de fin de vida, o a eutanasia.

Objective Ethical issues are extremely relevant in theoretical discussions in medicine, through the present article we intend to characterize patients with urologic conditions whose cases prompted consultations with the Clinical Ethics Service (CES) at a level-IV hospital in order to understand the prevalent ethical dilemmas encountered in the urological practice and their approach. Materials and Methods A descriptive study in which we performed a retrospective review of the clinical history of 20 urologic patients who were the subject of interconsultations with the CES of a level-IV hospital. We evaluated the frequency of the following variables: diagnosis, functional and clinical status at the time of the diagnosis, duration of disease evolution, and the type of ethical dilemma that prompted an interconsultation. Results Since January 2018, the CES at Hospital Universitario San Ignacio has received 1,123 interconsultation requests, and a significant increase in them has been observed due to the coronavirus disease 2019 (COVID-19) pandemic. Out of these interconsultations, only thirteen corresponded to patients with a urological diagnosis, and seven involved secondary urological compromise. The most frequent diagnosis was stage-IV prostate cancer, followed by advanced urothelial carcinoma. Proper treatment prevailed; only three cases were diagnosed at this stage, and they could not receive treatment. The main ethical dilemma involved treatment proportionality, in two cases, regarding patient autonomy, including one euthanasia request. Conclusion The established screening methods and effective early treatments are could lead to a low frequency of extreme clinical situations in which decision have to be made at the en

Antenatal oral glucose tolerance test in women with gestational diabetes mellitus: fasting plasma glucose is the best predictor of both large for-gestational-age newborns and postpartum glucose tolerance.

BACKGROUND: Numerous studies have evaluated the predictors of large-for-gestational-age newborns (LGA) as well as abnormal glucose tolerance (AGT) after delivery in women with gestational diabetes mellitus, one at a time. The present study assesses the ability of glucose values on the antenatal oral glucose tolerance test (OGTT) to predict both outcomes. METHODS: Retrospective analysis of a prospectively collected database. Gestational diabetes was diagnosed with a two-step approach. After delivery, reevaluation was performed using 2006 WHO definition of glucose tolerance. SELECTION CRITERIA: 1) singleton pregnancies; 2) available information on: offspring weight for age, antenatal and follow-up OGTT and additional potential predictors of LGA and AGT. The study included 1241 women. Data were analyzed by multivariate logistic regression and ROC analyses. Logistic regression models were used to calculate adjusted and unadjusted odds ratios and corresponding 95% CI for 1 mmol/L increase in each glucose value (FPG, 1 h, 2 h, 3 h) of the diagnostic 100-g OGTT, associated to the main outcomes LGA and postpartum AGT. RESULTS: Analyzing each glucose value on antenatal OGTT, fasting plasma glucose (FPG) showed the highest OR for both outcomes: LGA (1.537, 95% CI 1.237-1.910) and AGT (2.288, 95% CI 1.869-2.801). On the adjusted analysis the association was attenuated, but FPG continued to be the best predictor for both outcomes. CONCLUSIONS: In women with gestational diabetes mellitus, FPG on the diagnostic OGTT was the glycemic value that best predicted both LGA and after delivery AGT.

Bowel habits and fecal incontinence in patients with obesity undergoing evaluation for weight loss: the importance of stool consistency.

BACKGROUND: Fecal incontinence is highly prevalent in the general population and especially in risk groups. Obesity is also common and is associated with comorbidities that impair general health and interfere with daily activities. Identifying mutable factors for fecal incontinence, such as stool consistency, is of paramount importance to improve quality of life. OBJECTIVE: The aim of this study was to estimate the prevalence of fecal incontinence in patients with obesity undergoing evaluation for weight loss, its relationship with bowel habits, and its impact on quality of life. DESIGN: This investigation is a cross-sectional observational study. SETTINGS: This study was conducted in patients with obesity who were undergoing evaluation for weight loss. MAIN OUTCOME MEASURES: Fecal incontinence was defined as loss of flatus or liquid/solid stool occurring at least monthly. Data on comorbidities, BMI, quality of life, bowel habits including stool consistency measured with the Bristol Stool Form Scale, and symptoms of fecal incontinence were collected. RESULTS: Fifty-two patients were included, with a mean BMI of 39.6 kg/m2. Symptoms of fecal incontinence were found in 17 patients (32.7%): flatus in 9 of 17 (52.9%), liquid stool in 6 of 17 (35.2%), and solid stool in 2 of 17 (11.7%). No differences were found between patients with and without fecal incontinence in age, sex, comorbidities, or BMI. Health-related quality of life was lower in patients with fecal incontinence than in those without, but this difference was not significant, with the exception of the dimensions of role-physical (p = 0.03) and social functioning (p = 0.04). Patients with incontinence reported significantly higher percentages of altered bowel habits with nonformed stools (p = 0.004). LIMITATIONS: The cross-sectional design hampered identification of the time at which the impact of obesity occurred. CONCLUSIONS: Fecal incontinence is common in patients with obesity. Stool consistency was significantly different in these patients. This study supports the possibility of improving incontinence during weight loss by modifying stool consistency.

Differences in the Form of Presentation between Papillary Microcarcinomas and Papillary Carcinomas of Larger Size.

Papillary thyroid carcinomas (PTCs) with a diameter ≤1 cm are referred to as papillary microcarcinomas (PTMCs). The prognostic factors for PTMCs have not been defined. Different clinical and histopathologic variables were studied in 152 PTCs, including 74 PTMCs and 78 PTCs of larger size. We found that PTMCs are associated with less multifocality (P = .046) and bilaterality (P = .003), fewer lymphadenectomies (P < .001), and a higher rate of incidental tumours (P < .001). Moreover, patients with a low aggressive profile were significantly older than the remaining patients (54 ± 13.7 years versus 45.8 ± 13.1 years; P = .001). In conclusion PTMCs show significant differences compared to PTCs of larger size in the form of presentation. Furthermore, it is possible that the classic risk factors, which are well validated in PTCs, such as age, must be cautiously interpreted in the current increasing subgroup of PTMCs.
