RESUMO

AIMS: Patients' perception of their cleansing quality can guide strategies to improve cleansing during colonoscopy. There are no studies assessing the agreement between the quality of cleansing perceived by patients and cleansing quality assessed during colonoscopy using validated bowel preparation scales. The main aim of this study was to compare the cleansing quality reported by patients with the quality during colonoscopy using the Boston Bowel Preparation Scale (BBPS). PATIENTS AND METHODS: Consecutive patients referred to an outpatient colonoscopy were included. Four drawings representing different degrees of cleansing were designed. Patients chose the drawing that most resembled the last stool. The predictive ability of the patient's perception and agreement between the patient's perception and the BBPS were calculated. A BBPS score of <2 points in any segment was considered inadequate. RESULTS: Six hundred and thirty-three patients were included (age: 62.8±13.7 years, male: 53.4%). Overall, 107 patients (16.9%) had inadequate cleansing during colonoscopy, and in 12.2% of cases, the patient's perception was poor. The patient's perception compared to the quality of cleanliness during colonoscopy presented a positive and negative predictive value of 54.6% and 88.3%, respectively. The agreement between patient perception and the BBPS was significant (P<0.001), although fair (k=0.37). The results were similar in a validation cohort of 378 patients (k=0.41). CONCLUSIONS: The cleanliness perceived by the patient and the quality of cleanliness using a validated scale were correlated, although fair. However, this measure satisfactorily identified patients with adequate preparation. Cleansing rescue strategies may target patients who self-report improper cleaning. Registration number of the trial: NCT03830489.

RESUMO

BACKGROUND AND AIMS: Patients' perception of their bowel cleansing quality may guide rescue cleansing strategies before colonoscopy. The main aim of this study was to train and validate a convolutional neural network (CNN) for classifying rectal effluent during bowel preparation intake as "adequate" or "inadequate" cleansing before colonoscopy. PATIENTS AND METHODS: Patients referred for outpatient colonoscopy were asked to provide images of their rectal effluent during the bowel preparation process. The images were categorized as adequate or inadequate cleansing based on a predefined 4-picture quality scale. A total of 1203 images were collected from 660 patients. The initial dataset (799 images), was split into a training set (80%) and a validation set (20%). The second dataset (404 images) was used to develop a second test of the CNN accuracy. Afterward, CNN prediction was prospectively compared with the Boston Bowel Preparation Scale (BBPS) in 200 additional patients who provided a picture of their last rectal effluent. RESULTS: On the initial dataset, a global accuracy of 97.49%, a sensitivity of 98.17% and a specificity of 96.66% were obtained using the CNN model. On the second dataset, an accuracy of 95%, a sensitivity of 99.60% and a specificity of 87.41% were obtained. The results from the CNN model were significantly associated with those from the BBPS (P<0.001), and 77.78% of the patients with poor bowel preparation were correctly classified. CONCLUSION: The designed CNN is capable of classifying "adequate cleansing" and "inadequate cleansing" images with high accuracy.

RESUMO

Although the right to enjoy the highest level of mental and physical health that can be achieved is a universal human right, it has not been until very recent stages that mental health has begun to gain the relevance it deserves . Attention to maternal and child health exemplifies the limitations of the Spanish Health Service to offer comprehensive care that includes the dimension of mental health. For years, the main objective has been to combat preventable maternal mortality, practically eradicated in our country thanks to its health benefits . However, the enjoyment of health cannot be limited to achieving the survival of mothers and their babies, and good maternal health necessarily implies good perinatal mental health.


Aunque el derecho al goce del más alto nivel de salud mental y física que se pueda lograr es un derecho humano universal, no ha sido hasta etapas muy recientes que la salud mental ha empezado a cobrar la relevancia que merece . La atención a la salud materno-infantil ejemplifica las limitaciones de la Sanidad española para ofrecer una atención integral que incluya la dimensión de la salud mental. Durante años, el objetivo principal ha sido combatir la mortalidad materna prevenible, prácticamente erradicada en nuestro país gracias a sus prestaciones sanitarias . Sin embargo, el disfrute de la salud no puede limitarse a lograr la supervivencia de las madres y de sus bebés, y una buena salud materna implica, necesariamente, una buena salud mental perinatal.

RESUMO

Objective: We tested the hypothesis that an enhanced bowel preparation strategy (EBS) improves colonic cleansing in patients at high risk for inadequate bowel cleansing (HRI). Methods: This prospective randomized clinical trial included consecutive HRI patients referred for outpatient colonoscopy between February and October 2019. HRI was considered if patients scored >1.225 according to a previously validated bowel-cleansing predictive score. HRI patients were randomized (1:1) to a low-volume conventional bowel cleansing strategy (CBS) (1-day low residue diet (LRD) plus 2 L of polyethylene glycol (PEG) plus ascorbic acid) or to an EBS (3-day LRD plus 10 mg oral bisacodyl plus 4 L PEG). The Boston Bowel Preparation Scale (BBPS) was used to assess the quality of cleanliness. Intention-to-treat (ITT) and per protocol (PP) analyses were performed. A sample size of 130 patients per group was estimated to reach a 15% difference in favor of EBP. Results: A total of 253 HRI patients were included (mean age 69.8 ± 9.5 years, 51.8% women). No statistically significant differences were found in the BBPS scale between the two groups in the ITT analysis (CBS 76.8% vs. EBS 79.7%, P = 0.58) or PP analysis (CBS 78% vs. EBS 84.3%, P = 0.21), risk difference 2.9% (95% CI-7.26 to 39.16) in the ITT analysis, or risk difference 6.3% (95% CI-3.48 to 16.08) in PP analysis. No differences in preparation tolerance, compliance, adverse effects, or colonoscopy findings were found. Conclusion: EBS is not superior to CBS in hard-to-prepare patients.

RESUMO

Empleando un modelo de doble alternativa de elección: droga VS. alimento en perros sometidos a un cocainismo experimental, se encuentra que los animales tienden a elegir la droga a pesar de la administración de bromocriptina. Los resultados obtenidos viabilizan la propuesta de una prevalencia del condicionamiento clásico de señales en la instauración de la adicción cocaínica, al cual estaría asociado un condicionamiento operante de señales para el mantenimiento del comportamiento adictivo
