Relationship between pressure ulcer risk based on Norton Scale and on the "Eating/Drinking" need assessment.

AIM: To study the relationship between pressure ulcer risk evaluated by the Norton Scale and inadequate fulfilment of Need 2 (Eating/Drinking) from the 14-need classification designed by Virginia Henderson. BACKGROUND: Assessing nutritional status and skin condition to implement preventive measures are important nursing interventions. Our hospital's standard procedure requires recording Norton Scale and Henderson Eating/Drinking Assessment results. METHODS: This was a descriptive cross-sectional study, analysing case histories of 219 patients in medical/surgical wards for >24 hr with nursing care recorded in the GACELA Care computer application. Patient sociodemographic variables and evaluation concepts from the Norton Scale and Eating/Drinking were studied. RESULTS: A statistically significant relationship (p < 0.05; 95% CI: 0.61, 2.83) was seen between inadequate Eating/Drinking need fulfilment and increased pressure ulcer risk. Pressure ulcer risk was generally low in the sample, with mainly no or minimum risk (77.3%); the oldest age group had the highest risk. Self-care autonomy was the most frequently assessed item in Eating/Drinking (42%). CONCLUSIONS: A relationship was found between Norton Scale risk results and Eating/Drinking need assessment results. The greater the pressure ulcer risk, the more likely was inadequate need satisfaction (poor nutritional status). IMPLICATIONS: To help identify pressure ulcer risk, nurses should assess patients' eating independence. Safeguarding nutritional status and preventing pressure ulcers are nursing skills associated with quality nursing care.

Association between Anxiety Status and Hydration Status in Spanish University Students.

Anxiety disorders are a very common psychiatric pathology among young university students, and the strategies for its mitigation are limited to the consumption of anxiolytic substances. Adequate hydration is essential for staying healthy, as water is the main component of the human body and of several physiological processes. A state of dehydration, in addition to a negative water balance, has serious consequences on health status. We aimed to determine the association between the degree of anxiety and the level of hydration in Spanish university students. A cross-sectional, observational research study with a sample of 65 female university students was conducted. Over 90% of the study population shows anxiety levels above the 95th percentile. The individuals with anxiety above the 95th percentile showed a negative water balance. The consumption of coffee and herbal teas shows correlations with state anxiety and trait anxiety.

Characterisation of Zamorano-Leonese Donkey Milk as an Alternative Sustainably Produced Protein Food.

The Zamorano-Leonese donkey is the local breed of the Castilla y León region of Spain and is a protected endangered species. The best way to preserve it is to explore viable alternatives such as milk production. Unlike other donkey breeds, this one has not been previously characterised. The aim of this work is the complete nutritional characterisation of its milk for human consumption, either directly or as an ingredient, to meet the new consumer expectations of sustainability and health concerns. This breed did not differ from others in terms of amino acid and protein profile. Its low concentration of ß-lactoglobulin may be correlated to a low allergenicity. The presence of lactozyme and lactoferrin, which are potent antimicrobials, stand out among the proteins. This milk presented a higher content of unsaturated fatty acids, being oleic fatty acid the main one. Zamorano-Leonese donkey milk did have a higher content of vitamin C, riboflavin, folic acid and vitamin E than the other donkey breeds. It also had a high concentration of vitamin D despite its low-fat content. However, its mineral concentration was lower than other donkey breeds in line with its lower ash content. In terms of micronutrients, it had a high amount of zinc and selenium. Based on these results we can conclude that donkey milk is a food and/or ingredient with beneficial effects on cardiovascular health and the proper functioning of the immune system, as well as being a good source of protein. Therefore, donkey milk from this local species from Spain is a food and/or ingredient with beneficial nutritional properties and sustainable from an environmental point of view.

Changes in the Bone Mineral Density after Sleeve Gastrectomy vs. Roux-En-Y Gastric Bypass 2 Years after Surgery.

The aim of this study was to compare the analytical and densitometric changes 2 years after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). A retrospective study of a prospectively collected database was performed. Morbidly obese patients undergoing RYGB or SG, as primary bariatric procedures, were included. Weight loss; analytical levels of parathormone (PTH), vitamin D, and calcium; and densitometric parameters were investigated. In total, 650 patients were included in the study, and 523 patients (80.5%) underwent RYGB and 127 (19.5%) SG. There were no significant differences in excess weight loss at 24 months between both groups. When comparing preoperative and postoperative values, a significantly greater increase in PTH values was observed in the RYGB group, whereas there were no significant differences in calcium and vitamin D levels. The mean t-score values decreased after surgery at all the locations and in both groups. The reduction in the t-score was significantly greater in the RYGB group at the femoral trochanter and lumbar spine. A decrease in bone mineral density (BMD) was observed after both techniques. The mean BMD decrease was significantly greater in the femoral trochanter and lumbar spine after RYGB.

Dielectric Barrier Discharge for Solid Food Applications.

Atmospheric cold plasma (ACP) is a non-thermal technology whose ability to inactivate pathogenic microorganisms gives it great potential for use in the food industry as an alternative to traditional thermal methods. Multiple investigations have been reviewed in which the cold plasma is generated through a dielectric barrier discharge (DBD) type reactor, using the atmosphere of the food packaging as the working gas. The results are grouped into meats, fruits and vegetables, dairy and lastly cereals. Microbial decontamination is due to the action of the reactive species generated, which diffuse into the treated food. In some cases, the treatment has a negative impact on the quality. Before industrializing its use, alterations in colour, flavour and lipid oxidation, among others, must be reduced. Furthermore, scaling discharges up to larger regions without compromising the plasma homogeneity is still a significant difficulty. The combination of DBD with other non-thermal technologies (ultrasound, chemical compounds, magnetic field) improved both the safety and the quality of food products. DBD efficacy depends on both technological parameters (input power, gas composition and treatment time) and food intrinsic properties (surface roughness, moisture content and chemistry).

Assessment of Risk Factors Associated with Cardiovascular Diseases in Overweight Women.

The assessment of anthropometric variables has been shown to be useful as a predictor of cardiovascular risk in overweight and obese patients. The aim of this study was to determine the usefulness of the relationship between breast volume and body mass index as an indicator of cardiovascular risk in premenopausal women with overweight and mild obesity. A prospective observational study of 93 premenopausal women was performed. Evaluation of anthropometric measures included age, body mass index, waist and hip circumferences, breast projection, and ptosis. Cardiovascular risk factors were evaluated using the Framingham cardiovascular risk score, the triglycerides/HDL cholesterol ratio and the waist-hip ratio. Ninety-three women were included, with a mean 36.4 ± 7.5 years. Mean BMI was 27.3 ± 1.9 kg/m2, waist-to-Hip ratio was 0.8 ± 0.07, and mammary volume was 1045 ± 657.4 cm3. Mean body fat mass was 30.6 + 3.6% and mean visceral fat was 6.6 + 3.2%. The mean triglycerides to HDL ratio was 1.7 ± 0.8 and waist-to-hip ratio was 0.8 ± 0.07. Breast volume related to body mass index can be used as a predictor of cardiovascular risk in premenopausal women who are overweight and mildly obese.

The Impact of COVID-19 on Levels of Adherence to the Completion of Nursing Records for Inpatients in Isolation.

The COVID-19 pandemic has led to an increased workload for nurses and organisational and structural changes, which have been necessary to meet the needs of inpatients in isolation. AIM: To describe the impact of the COVID-19 pandemic on levels of adherence to the completion of nursing records that document the risk of developing pressure ulcers, falling, and social vulnerability among hospitalised patients in isolation. METHODS: Observational pre-post comparison study. Comparison between nursing records (the Braden, Downton, and Gijón scales) belonging to 1205 inpatients took place in two phases. Phase 1: 568 patients admitted in February 2020, prior to the COVID-19 pandemic, vs. phase 2: 637 patients hospitalised with COVID-19 in March-April 2020, during the peak of the first wave of the pandemic. This research adheres to the STROBE guidelines for the reporting of observational studies. RESULTS: The degree of completion of the Braden, Downton, and Gijón scales decreased significantly in phase 2 vs. phase 1 (p < 0.001). The mean Downton and Gijón scale scores for patients admitted in phase 1 were higher compared to those of patients admitted in phase 2 (p < 0.001). The mean Braden scale score in phase 2 was higher than in phase 1 (p < 0.05). CONCLUSION: During the COVID-19 pandemic, there was a decrease in the completion of nursing records in the clinical records of patients in isolation. The levels of risk of developing PUs, falling, and social vulnerability of patients admitted to hospital were lower during the first wave of the pandemic.

Development of critical thinking skills of undergraduate students throughout the 4 years of nursing degree at a public university in Spain: a descriptive study.

OBJECTIVE: To analyse the critical thinking skills of students enrolled in the four academic years of the nursing degree at a public university belonging to the European Higher Education Area. DESIGN: Cross-sectional, quantitative, descriptive study. Using the Critical Thinking Questionnaire to analyse the critical thinking skills in their substantive and dialogic dimension. SETTING: Faculty of Nursing, Valladolid Public University in Spain, belonging to the European Higher Education Area. PARTICIPANTS: The sample consisted of 215 first-year, second-year, third-year and fourth-year undergraduate nursing students. MAIN OUTCOMES: The students of the four academic years were positively disposed towards critical thinking. The students of the final courses obtained higher average scores. RESULTS: The study sample was 215 students, 19.1% men/80.9% women. The average score in the substantive dimension (3.81±0.53 points) was higher than that in the dialogic dimension (3.48±0.51 points) (p<0.001). They had a greater ability in listening and speaking (3.77±0.61 points) with respect to writing (3.65±0.61 points) and reading (3.52±0.43 points) (p<0.001). There are significant differences in the critical thinking average scores across academic years. CONCLUSIONS: Nursing students displayed a greater critical thinking ability in its substantive dimension compared with the dialogic one. This reflects a greater ability in actions related to provide reasons and evidence that support their point of view. Identifying critical thinking skills in nursing students will help establish specific teaching methodologies focused on improving these skills.

Impact of Preoperative Total Proteins and Glycated Hemoglobin on Recurrences after Early Colorectal Cancer.

BACKGROUND: The outcome of colorectal cancer is mostly based on TNM classification. There are several factors determining that patients with the same tumoral stage present different outcomes. The nutritional status has been related to the immunological response and may affect the oncologic results. The purpose of this study was to determine if preoperative nutritional parameters may predict the oncologic outcome in patients with early colorectal cancer. METHODS: A prospective observational study of patients undergoing elective surgery for colorectal cancer was performed with stage I. Preoperative nutritional assessment included glycemic and lipid profiles, total proteins, and albumin levels. These parameters were correlated with tumoral recurrence during a follow-up of at least 24 months. RESULTS: During the period of study, 744 patients were operated on and 228 (30.6%) followed the inclusion criteria for this study. Recurrence rate was 5.7% (13 patients). Patients with hypoproteinemia showed a 7.8-fold greater risk of recurrence during the first 24 months after surgery [OR 7.8 (CI95% 1.3-48), p = 0.012]. Patients with glycated hemoglobin levels (HbA1c) > 6.2% showed a 2.3 increased risk of recurrence [OR 2.3 (CI95% 1.1-4.7; p = 0.01]. CONCLUSIONS: Preoperative values of total proteins and HbA1c correlate with the recurrence rate in early colorectal cancer.

Assessment of an Educational Intervention to Improve Healthy Life Habits in Children Living in Vulnerable Socioeconomic Conditions.

Nutritional condition impacts academic performance and cognitive development. In Peru, the prevalence of chronic undernutrition in children is 6.9%, increasing the risk of mortality and morbidity. This study aimed to develop an educational intervention to achieve an improvement in the healthy habits of children in a primary education school in Lima who live in vulnerable socioeconomic conditions. We conducted a prospective quasi-experimental pre-test and post-test study of an educational intervention. The information was collected through the adaptation of the WHO questionnaire "Global School-based Student Health Survey" (GSHS), with anthropometric variables, socioeconomic level, hygiene and eating habits. One hundred eight students from 5 to 13 years old from Arenitas del Mar School in Lima (Peru) participated. The educational intervention improved eating habits. Fruit and vegetable consumption 3 or more times/day (50.9%) increased after the educational intervention (49% vs. 62.9%,) p < 0.0001. There was an improvement in hygiene habits, such as the frequency of handwashing with soap (32.4% vs. 63.9%) and the frequency of weekly bathing 4-6 times/week (25% vs. 47.5%) p < 0.0001. The educational intervention promoted better healthy living behaviors, eating habits and hygiene. This kind of initiative is a crucial tool to establish healthy living habits.

Analysis of Burnout Syndrome and Resilience in Nurses throughout the COVID-19 Pandemic: A Cross-Sectional Study.

BACKGROUND: The COVID-19 pandemic has contributed to the occurrence of work-related stress on nursing staff. Being resilience an essential element to countering adversity. The aim of the study was to assess burnout syndrome as well as resilience in hospital-care nurses during the first outbreak of the COVID-19 pandemic. METHODS: A cross-sectional descriptive study of burnout syndrome and resilience of 101 nurses during the first COVID-19 outbreak. The Maslach Burnout Inventory and the Scale of Resilience of Connor-Davidson were used. RESULTS: The burnout average score was 74.35 ± 12.78 points, and resilience was 27.94 ± 5.84. Temporary nurses reached a lower average score for the emotional fatigue dimension (23.80 ± 10.39 points) p < 0.05. The emotional fatigue dimension correlated adversely with the average score of resilience (r = -0.271; p < 0.001). CONCLUSIONS: The level of burnout in nurses was high, being higher on those who took care of COVID-19 patients. Resilient nurses were able to better cope with stressful situations.

Changes in Lipid Profile, Body Weight Variables and Cardiovascular Risk in Obese Patients Undergoing One-Anastomosis Gastric Bypass.

Morbid obesity has a direct impact on the development of cardiovascular disease. One-anastomosis gastric bypass (OAGB) is an effective surgical technique for the control of body weight and the reduction of cardiovascular risk. This work examines the change in weight loss, lipid profile and cardiovascular risk in 100 patients (71 women, 29 men), mean age 42.61 ± 11.33 years at 3, 6, 9, 12, 18 and 24 months after OAGB. At 24 months post-surgery, mean body weight was significantly reduced compared to pre-operative values (116.75 ± 22.19 kg vs. 69.66 ± 13.07 kg), as were mean total cholesterol (201.86 ± 44.60 mg/dL vs. 172.99 ± 32.26 mg/dL), LDL (Low-Density Lipoprotein) cholesterol (126.90 ± 39.81 mg/dL vs. 96.28 ± 26.99 mg/dL), triglycerides (138.05 ± 78.45 mg/dL vs. 76.04 ± 30.34 mg/dL) and cardiovascular risk (total cholesterol/HDL (High-Density Lipoprotein) cholesterol: 4.32 ± 1.24 vs. 2.93 ± 0.71), while the mean HDL cholesterol concentration was significantly higher (49.09 ± 14.16 mg/dL vs. 61.98 ± 14.86 mg/dL) (all p < 0.001). In conclusion, OAGB surgery led to significant reductions in body weight, a significant improvement in the lipid profile, and a reduction in cardiovascular risk.

Implications of Professional Occupation Related to Obesity in Patients Undergoing Bariatric Surgery.

Obesity is an epidemic with severe consequences on the professional development of patients. Bariatric surgery has proven to be a safe treatment with effective results in weight control. The aim of this study is to assess the implications of professional occupation in relation to the development of obesity and weight changes after bariatric surgery. We analyzed 500 obese patients (77.8% women, 22.2% men) who underwent one anastomosis gastric bypass surgery at the Centre of Excellence for the Study and Treatment of Obesity and Diabetes (2014-2019), assessing the influence of professional occupation on body composition and evolution of weight loss up to two years after surgery. Preoperative obesity type III and IV was higher in men than in women (45.9-19.8% vs. 43.7-9.5%; respectively). Prevalent clinical history in women was depression (46.7%), varicose veins (35.6%), and thyroid disease (9.7%), while in men it was respiratory failure (98.2%), high blood pressure (56.8%), hepatic steatosis (82%). Postoperative weight loss was effective in every professional field, reaching normal weight values from 12 months after surgery.

Type 1 Diabetes Mellitus in Pediatric Patients and Its Impact on Relationships in the Family Environment.

PURPOSE: The aim of this study is to assess the impact of type 1 diabetes mellitus on family environment relationships, as well as the management and approach to this disease. PATIENTS AND METHODS: One hundred one children, 52.47% male and 47.52% female, with an average age of 8.55 ± 4.01 years, diagnosis of type 1 diabetes mellitus. Quantitative cross-sectional descriptive study was conducted using the validated questionnaires "Modified Diabetes Quality of Life" and "Questionnaire for the assessment of psychological impact in parents/guardians of diabetic children". RESULTS: Most of the children (70.3% versus 29.7%) identified diabetes as unpleasant or not fun. The ≤5-year-olds expressed that they felt concerned about the consequences of being diabetic (8.1% by age group), as opposed to the 10-year-olds who did not feel concerned (85.1% by age group), P <0.001. The family environment was affected in 98.1% (n=99) of the cases. CONCLUSION: Self-care of type 1 diabetes mellitus in pediatric patients is a complex process that impacts the family environment and their relationship with their peers, especially for children under the age of 5. Fear, concern and insecurity were prevalent feelings in children suffering type 1 diabetes mellitus.

Long-Term Weight Loss Results, Remission of Comorbidities and Nutritional Deficiencies of Sleeve Gastrectomy (SG), Roux-En-Y Gastric Bypass (RYGB) and One-Anastomosis Gastric Bypass (OAGB) on Type 2 Diabetic (T2D) Patients.

This study aimed to compare the long-term weight loss results, remission of comorbidities and nutritional deficiencies of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB) and One-Anastomosis gastric bypass (OAGB) on type 2 diabetic (T2D) patients. PATIENTS AND METHODS: A retrospective analysis of all the morbidly obese and diabetic patients undergoing SG, RYGB, and OAGB as primary bariatric procedures between February 2010 and June 2015 was performed. Anthropometric parameters, remission of comorbidities, nutritional deficiencies and supplementation requirements at 1, 2 and 5 years' follow-up were monitored. Patients lost to follow-up 5 years after surgery were excluded from the analysis. RESULTS: 358 patients were included. The follow-up rate was 84.8%. Finally, 83 SG, 152 RYGB, and 123 OAGB patients were included in the analysis. OAGB obtained significantly greater weight loss and remission of dyslipidemia than the other techniques. There was a trend towards greater T2D and hypertension remission rate after OAGB, while fasting glucose and glycated hemoglobin levels were significantly lower after OAGB. There were no significant differences in hemoglobin or protein levels between groups. SG obtained lower iron deficiencies than the other techniques, while there were no significant differences in other nutritional deficiencies between groups. CONCLUSION: OAGB obtained greater weight loss and remission of dyslipidemia than RYGB or SG. Excluding lower iron deficiency rates after SG, there were no significant differences in the development of nutritional deficiencies between groups.

The impact of an educational intervention on nursing students' critical thinking skills: A quasi-experimental study.

AIM: In this study, we identified the impact of educational activities that focused on improving the competence and critical thinking skills of university nursing students. DESIGN: A prospective quasi-experimental study was conducted, and assessments were conducted before and after the educational intervention, which consisted of seminars, lectures, case studies, and problem-solving activities. METHODS: The Critical Thinking Questionnaire was used to collect data before and after the educational intervention between September 2017 and May 2018. The sample consisted of 112 first-year undergraduate students. To examine the data that were collected as a part of this quasi-experimental study, inferential statistics were used, and the results were tested against a significance level of P < 0.05. RESULTS: The students obtained higher scores on the substantive dimension than on the dialogic one, and women scored higher than men. The educational intervention led to an improvement in every critical thinking skill across both dimensions, except listening and speaking skills, whereby men demonstrated a greater change in average scores for critical thinking skills. CONCLUSIONS: The educational intervention improved the critical thinking skills of undergraduate students and had a greater impact on men than on women. This finding underscores the need for educational interventions that can enhance critical thinking skills. Developing these skills will improve future nurses' ability to make health care management decisions in a reflective, agile, and evidence-based manner.

Impact of Nursing Methodology Training Sessions on Completion of the Virginia Henderson Assessment Record.

The Virginia Henderson model, integrated in the computer application GACELA Care, helps to standardise the nursing assessment and establish precise and personalised nursing diagnoses. The aim was to determine the extent of completion of the initial patient assessment record after nurses following a training programme on nursing methodology. A quasi-experimental, retrospective, randomised, observational, single-group study was performed in two stages: pre-training and post-training. Voluntary training sessions were held for the nurses that work with GACELA Care. The completion of the initial patient assessment using the needs of Virginia Henderson and the Norton scale was evaluated before and after the training sessions. Completion of the needs of Virginia Henderson in the initial patient assessment increased from 94.2% to 100% (p = 0.014). Completion of "hygiene/skin" increased significantly from 83.3% to 95.8% (pre-training and post-training, respectively). The remaining needs did not show statistical significance. Recording of the Norton scale increased from 63.13% to 92.5% (p < 0.001). The training sessions on nursing methodology have improved the completion of records and inclusion of normal characteristics, defining characteristics and risk factors, and improving pressure ulcer risk assessment through the Norton scale.

Assessment of body composition in obese patients undergoing one anastomosis gastric bypass: cross-sectional study.

Bariatric surgery is the most effective long-term treatment to obesity, and it is necessary to assess changes in body composition and to be able to establish better follow-up of patients. Cross-sectional, observational study in patients undergoing One Anastomosis Gastric Bypass (OAGB) bariatric surgery. We analysed changes in weight and body composition during the first postoperative year. 405 patients (68.9% women. 31.1% men), mean age 44 years, mean weight 110.02 kg, Body Mass Index (BMI) 39.76 kg/m2, height 1.66 m. The variables analyzed were substantially decreased compared to the preoperative values one year after surgery in every case: weight (110.02 ± 22.03 kg vs. 69.36 ± 13.60 kg), BMI (39.76 ± 6.65 vs. 24.52 ± 3. 76), fat free mass (61.12 ± 12.43 kg vs. 53.61 ± 11.61 kg), fat mass (50.44 ± 14.36 kg vs. 15.74 ± 6.74 kg), bone mass (58.06 ± 11.85 kg vs. 50.92 ± 11.06 kg) and water (45.08 ± 9.99 kg vs. 37.39 ± 9.23 kg), P < 0.001. The results show noticeable improvements in weight reduction and changes in body composition, and will contribute to develop a thorough understanding of both of them, contributing also to perform a better patients' follow-up.

Impact of educational games on academic outcomes of students in the Degree in Nursing.

OBJECTIVE: The aim of using the game-based tool Kahoot! was to evaluate and reinforce the contents taught in the subject of Management and Administration of Nursing, Ethics and Health Legislation Services included in the Degree in Nursing, during the 2016-2017 academic year. METHODS: A prospective quasi-experimental study was carried out on a sample of 116 students. 10 multiple-choice questions were designed, with only one possible correct answer and a 20-second-limited response time for each of the questions. Four of these questions previously answered in the classroom using this game were chosen (20% of the exam). Each one of them corresponded to one unit of the topics taught in the subject. In order to participate in the educational game, students needed their smartphones or electronic devices. After completing the game, the students' satisfaction level derived from its use was assessed. RESULTS: The correct answer rate in the educational game was greater than 50% for all questions except for one, in which the rate was 28.8% (P<0.05). Response time as related to score presented statistically significant differences, and higher scores for those questions with lower response time (P<0.001). The questions included in the final test which had been previously answered using Kahoot! showed a significantly higher difficulty index than the rest of the final exam questions (P<0.05). Question 3 was the easiest, while being the one in which the highest-scoring students obtained more wrong answers. For the students this tool was easy to use (89.6%) and they positively valued the content acquisition and comprehension, as well as the teacher-student interaction (P<0.05). CONCLUSION: The implementation of educational games which consider response time and correct answers favors competitiveness and motivates students to actively participate in their learning process.

Evaluation of Weight Loss Indicators and Laparoscopic One-Anastomosis Gastric Bypass Outcomes.

Mini-gastric bypass/One-anastomosis gastric bypass (MGB-OAGB) is an effective bariatric technique for treating overweight and obesity, controlling and improving excess-weight-related comorbidities. Our study evaluated OAGB characteristics and resulting weight evolution, plus surgical success criteria based on various excess weight loss indicators. A prospective observational study of 100 patients undergoing OAGB performed by the same surgical team (two-year follow-up). Surgical characteristics were: surgery duration, associated complications, bowel loop length, hospital stay, and weight loss at 6 postoperative points. 100 patients were treated (71 women, 29 men); mean initial age was 42.61 years and mean BMI, 42.61 ± 6.66 kg/m2. Mean surgery duration was 97.84 ± 12.54 minutes; biliopancreatic loop length was 274.95 ± 23.69 cm. Average hospital stay was 24 hours in 98% of patients; no surgical complications arose. Weight decreased significantly during follow-up (P < 0.001). Greatest weight loss was observed at 12 months postsurgery (68.56 ± 13.10 kg). Relative weight loss showed significant positive correlation, with greatest weight loss at 12 months and %excess BMI loss > 50% achieved from the 3-month follow-up in 92.46% of patients. OAGB seems to be effective in treating obesity, with short hospital stays. Relative weight loss correlates optimally with absolute outcomes, but both measures should be used to evaluate surgical results.
