ABSTRACT
OBJECTIVES: This study aimed to explore the clinical characteristics of amyotrophic lateral sclerosis (ALS) patients in Spain's north-eastern region, their inclusion in chronic care programmes, and their psychosocial and spiritual needs (PSNs). METHODS: A longitudinal descriptive study in adult patients with ALS. We analyzed clinical variables and participation in chronicity and PSNs assessment using the tool Psychosocial and Spiritual Needs Evaluation scale in end-of-life patients (ENP-E scale). RESULTS: 81 patients (average age 65.6 ± 11.7) were studied. At the study's outset, 29.7% employed non-invasive ventilation (NIV), increasing to 51.9% by its conclusion. Initial percutaneous endoscopic gastrostomy (PEG) utilization was 14.8%, rising to 35.85%. Chronic care programme participation was as follows: home care (24.7% initially, 50.6% end), palliative care (16% initially, 40.7% end), case management (13.6% initially, 50.6% end), and advance care planning registration (6.2% initially, 35.8% end). At study start, 47.8% of patients (n = 46) showed moderate-to-severe complexity in PSNs assessment using the ENP-E scale, without showing differences in age, sex, and time of evolution; whereas, on the evolutionary analysis, it was 75% (n = 24). A higher evolutionary complexity was observed in males <60 and >70 years, with no PEG and evolution of ALS of <2 and ≥5 years, and not included in chronicity programmes. When assessing concerns, physical pain and family aspects stand out in all measurements. Forty-eight percent of patients at study start and 71% at end of study showed external signs of emotional distress. SIGNIFICANCE OF RESULTS: Most ALS patients showed a high degree of complexity and were not integrated in chronicity programmes. A "care path" is proposed to integrate ALS patients in these programmes and systematically assess their needs.

BACKGROUND: It is known that standardized incidence rates of hip fracture vary among older people in Spain. So far, the results published on the validation of the FRAX® tool in Spain have suggested that the major osteoporotic fractures (MOFs) risk in our country is underestimated. These studies have practically been based on Spanish cohorts evaluated in Catalonia, a higher hip fracture rate area. The purpose of this study is to analyse the ability of the FRAX® in a Spanish mid-fracture rate population. METHODS: Study design: Retrospective cohort study. MEASURES: MOFs: hip, humerus, wrist, spine fractures. Risk of fracture assessed by calculating odds ratios (ORs). Predictive capacity of FRAX® according to the osteoporotic fractures observed between 2009 and 2018 (ObsFr) to predicted by FRAX® without densitometry in 2009 (PredFr) ratio. RESULTS: 285 participants (156 women, 54.7%) with a mean ± SD of 61.5 ± 14 years. Twenty-four people sustained 27 fractures (15 MOFs). Significant ORs were observed for an age ≥ 65 (2.92; 95% CI, 1.07-7.96), female sex (3.18; 95% CI, 1.24-8.16), rheumatoid arthritis (0.62; 95% CI, 2.03-55.55), proton pump (2.71; 95% CI, 1.20-6.09) and serotonin reuptake (2.51; 95% CI, 1.02-6.16) inhibitors. The ObsFr/PredFr ratio in women were 1.12 (95% CI, 0.95-1.29) for MOFs and 0.47 (95% CI, 0-0.94) for hip fractures. Men had a ratio of 0.57 (95% CI, 0.01-1.14) for MOF, no hip fractures were observed. The ratios for the overall group were 1.29 (95% CI, 1.12-1.48) for MOFs and 0.70 (95% CI, 0.22-1.17) for hip fractures. CONCLUSIONS: FRAX® accurately predicted MOFs in women population with a hip fracture incidence rate close to the national mean compared to previous studies conducted in higher incidence regions in Spain.

Background and Objectives: Differentiating between hypovolemic (HH) and euvolemic hyponatremia (EH) is crucial for correct diagnosis and therapy, but can be a challenge. We aim to ascertain whether changes in serum creatinine (SC) can be helpful in distinguishing HH from EH. Materials and Methods: Retrospective analysis of patients followed in a monographic hyponatremia outpatient clinic of a tertiary hospital during 1 January 2014−30 November 2019. SC changes during HH and EH from eunatremia were studied. The diagnostic accuracy of the SC change from eunatremia to hyponatremia (∆SC) was analyzed. Results: A total of 122 hyponatremic patients, median age 79 years (70−85), 46.7% women. In total, 70/122 patients had EH, 52/122 HH. During hyponatremia, median SC levels increased in the HH group: +0.18 mg/dL [0.09−0.39, p < 0.001], but decreased in the EH group: −0.07 mg/dL (−0.15−0.02, p < 0.001), as compared to SC in eunatremia. HH subjects presented a higher rate of a positive ∆SC than EH (90.4% vs. 25.7%, p < 0.001). EH subjects presented a higher rate of a negative/null ∆SC than HH (74.3% vs. 9.6%, p < 0.001). ROC curve analysis found an AUC of 0.908 (95%CI: 0.853 to 0.962, p < 0.001) for ∆SC%. A ∆SC% ≥ 10% had an OR of 29.0 (95%CI: 10.3 to 81.7, p < 0.001) for HH. A ∆SC% ≤ 3% had an OR of 68.3 (95%CI: 13.0 to 262.2, p < 0.001) for EH. Conclusions: The assessment of SC changes from eunatremia to hyponatremia can be useful in distinguishing between HH and EH.

BACKGROUND: Assessment health literacy in people with cardiovascular health problems would facilitate the development of appropriate health strategies for the care and reduction of complications associated with oral anticoagulation therapy. AIM: To evaluate the relationship between health literacy and health and treatment outcomes (concordance with oral anticoagulants, Normalized Ratio control and occurrence of complications) in patients with cardiovascular pathology. METHODS: Observational, analytic and cross-sectional study carried out on 252 patients with cardiovascular pathology (atrial fibrillation, flutter or valve prosthesis), aged 50-85 years, accessing primary care services in Valencia (Spain) in 2018-2019. Variables referring to anticoagulant treatment with vitamin K antagonists (years of treatment, adequate control, polypharmacy and occurrence of complications, among others) and health literacy (Health Literacy Questionnaire) were analysed. RESULTS: All dimensions of health literacy were significantly related to the level of education (p < 0.02), social class (p < 0.02), an adequate control of acenocoumarol (p < 0.001), frequentation of health services (p < 0.001), information by patients to health professionals about anticoagulant treatment (p < 0.03), emergency care visits (p < 0.001) and unscheduled hospital admissions (p < 0.001). CONCLUSION: Health literacy has a relevant influence on the adequate self-management of anticoagulation treatment and the frequency of complications. The different dimensions that comprise health literacy play an important role, but the "social health support" dimension seems to be essential for such optimal self-management. TRIAL REGISTRATION: ACC-ACE-2016-01. Registration date: December 2015.

The development of criteria and indicators to quantify the transition to sustainability of the urban socio-ecological systems quality is determinant for planning policies and the 21st century urban agenda. This study models the spatial variation in the concentration and distribution of some macronutrients, micronutrients, and trace nutrients in the soil of a high-altitude city in the Andes. Meanwhile, machine learning methods were employed to study some interactions between the different dimensions that constitute an urban socio-ecosystem that caused these variations. We proposed a methodology that considered two phases: a) field work to collect data on 300 soil samples; laboratory analysis to measure the concentrations of 24 macronutrients, micronutrients, and trace nutrients; and the design of geophysical, spectral, and urban co-variables; b) statistical and geo-informatics analysis, where multivariate analysis grouped the elements into factors; and, machine learning integrated with co-variables was applied to derive the intensity of each factor across the city. Multivariate statistics described the variation in soil co-concentrations with a moderate percentage (42%). Four factors were determined that grouped some of the analyzed elements, as follows: F1 (Zn, S, Cu, Pb, Ni, and Cr), F2 (Ba, Ag, K, In, and Mg), F3 (B, V, Li, and Sr), and F4 (Si and Mn). The percentage R2 out-of-bag of the spatial model were: F1 = 20%, F2 = 8%, F3 = 14%, and F4 = 10%. Our outputs show that the enrichment and contamination by anthropogenic factors, such as the increase in population density, land use, road network, and traffic generated by fossil fuel vehicles, should be prioritized in urban planning decisions.

PURPOSE: To evaluate pharmacokinetic parameters of ciprofloxacin in patients undergoing Roux-en-Y gastric surgery (RYGS). METHODS: Controlled, single-dose, open-label study in patients undergoing RYGS. Healthy overweight/obese patients 18-60 years old were included. The assessment was performed once in control patients and three times in case patients (before surgery and 1 and 6 months after surgery). In each visit, the subjects received a single oral dose of ciprofloxacin 500 mg. Venous blood samples were obtained at baseline and 0.5, 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 8 and 14 h after ciprofloxacin intake. Pre- and post-surgery variables were compared using paired ANOVA or the Wilcoxon tests and control vs cases using ANOVA or Mann Whitney. Given the post-surgery change in body weight, the parameters were corrected by dose (mg)/body weight (kg). The analysis was performed using SPSS. RESULTS: Ciprofloxacin Cmax was significantly reduced 1 month after surgery (1840.9 ± 485.2 vs 1589.6 ± 321.8 ng/ml; p = 0.032) but not 6 months after. Cmax on the sixth month was lower than Cmax in control group (2160.4 ± 408.6 vs 1589.6 ± 321.8 ng/ml; p < 0.001). After correcting by the dose (mg)/patient's body weight, both Cmax and AUClast showed significant decrease 1 and 6 months after surgery: Cmax, 289.1 ± 65.3 and 263.5 ± 52.1 (ng/ml)/(dose (mg)/weight (kg)) respectively vs 429.3 ± 127.6 (ng/ml)/(dose (mg)/weight (kg)) at baseline; AUC, 1340.6 ± 243.0 and 1299.2 ± 415.4 (h × ng/ml)/(dose (mg)/weight (kg)) respectively vs 1896.7 ± 396.8 (h × ng/ml)/(dose (mg)/weight (kg)) at baseline. Cmax 1 month post-surgery showed lower values than the control group (375.4 ± 77.4 vs 263.5 ± 52.1 ng/ml; p < 0.001). CONCLUSION: Ciprofloxacin absorption is impaired 1 month and 6 months after RYGS. The effect on Cmax and AUClast faded on the sixth month due to weight loss. It is no necessary to modify the doses of ciprofloxacin in these patients.

PURPOSE: Migration of nurses is not a new or recent event. During the past few decades, nursing migration flows have been a constant trend worldwide. The main objective of this study was to explore the motivations, beliefs, and expectations that Spanish nurses had when considering migration to another country in the near future. DESIGN: Cross-sectional, Internet survey of Spanish nurses planning migration for professional reasons. METHODS: Ad hoc, web-based questionnaire following the Nurses Early Exit Study guidelines. FINDINGS: One hundred seventy-two nurses responded. Fifty percent of the participants intended to emigrate in the following 6 months and had chosen the United Kingdom as their destination. The most important drivers of migration were unemployment or precarious employment, and professional development. Fifty-eight percent of the participants were very afraid of experiencing discrimination or rejection. CONCLUSIONS: This first study conducted in Spain directly exploring determinants of nurse migration highlighted globalization-driven factors and specific acculturation fears. CLINICAL RELEVANCE: Employment uncertainty and professional development remain key push drivers for migration of Spanish nurses. Discrimination and rejection due to migrancy were concerns for 60% of the participants.

BACKGROUND: Primary skin tumors that develop at enteral feeding stomas are extremely rare. Ongoing surveillance of these stomas, including the peristomal skin, is essential to early diagnosis and treatment of these tumors. CASE: A 73-year-old man with an esophageal chemical burn caused by swallowing sodium hypochlorite (bleach) approximately 50 years earlier that was initially managed with esophageal exclusion and placement of a gastrostomy device for enteral feeding presented with an exophytic and painful mass of the skin adjacent to his gastrostomy site. The pathologic report confirmed differentiated squamous cell skin carcinoma. CONCLUSION: Skin tumors arising from chronic wounds or ulcers of the skin surrounding a gastrostomy device are rare but should be considered if hypergranulation tissue or a peristomal lesion appears to be nonhealing. WOC nurses are frequently consulted for care of granulomas, and close monitoring is essential for avoiding this potentially fatal complication.

BACKGROUND: The FRAX® tool estimates the risk of a fragility fracture among the population and many countries have been evaluating its performance among their populations since its creation in 2007. The purpose of this study is to update the first FRIDEX cohort analysis comparing FRAX with the bone mineral density (BMD) model, and its predictive abilities. METHODS: The discriminatory ability of the FRAX was assessed using the 'area under curve' of the receiver operating characteristic (AUC-ROC). Predictive ability was assessed by comparing estimated risk fractures with incidence fractures after a 10-year follow up period. RESULTS: One thousand three hundred eight women ≥ 40 and ≤ 90 years followed up during a 10-year period. The AUC for major osteoporotic fractures using FRAX without DXA was 0.686 (95 % CI 0.630-0.742) and using FN T-score of DXA 0.714 (95 % CI 0.661-0.767). Using only the traditional parameters of DXA (FN T-score), the AUC was 0.706 (95 % CI 0.652-0.760). The AUC for hip osteoporotic fracture was 0.883 (95 % CI 0.827-0.938), 0.857 (95 % CI 0.773-0.941), and 0.814 (95 % CI 0.712-0.916) respectively. For major osteoporotic fractures, the overall predictive value using the ratio Observed fractures/Expected fractures calculated with FRAX without T-score of DXA was 2.29 and for hip fractures 2.28 and with the inclusion of the T-score 2.01 and 1.83 respectively. However, for hip fracture in women < 65 years was 1.53 and 1.24 respectively. CONCLUSIONS: The FRAX tool has been found to show a good discriminatory capacity for detecting women at high risk of fragility fracture, and is better for hip fracture than major fracture. The test of sensibility shows that it is, at least, not inferior than when using BMD model alone. The predictive capacity of FRAX tool needs some adjustment. This capacity is better for hip fracture prediction and better for women < 65 years. Further studies in Catalonia and other regions of Spain are needed to fine tune the FRAX tool's predictive capability.

One of the main limiting aspects in the application of crown fire models at landscape scale has been the uncertainty derived to describe canopy fuel stratum. Available crown fuel and canopy bulk density are essential in order to simulate crown fire behaviour and are of potential use in the evaluation of silvicultural treatments. Currently, the more accurate approach to estimate these parameters is to develop allometric models from common stand inventory data. In this sense, maritime pine (Pinus pinaster Aiton) trees were destructively sampled in the South of the Iberian Peninsula, covering natural and artificial stands. Crown fine fuel was separated into size classes and allometric equations that estimate crown fuel load by biomass fractions were developed. Available crown fuel was determined according to the fuel load differences between un-burned and burned trees with similar characteristics. Taking our destructive post-fire inventory into account, available crown fuel was estimated as the sum of needles biomass, 87.63% of the twigs biomass and 62.79% of the fine branches biomass. In spite of the differences between natural and artificial stands, generic models explained 82% (needles biomass), 89% (crown fuel), 92% (available crown fuel) and 94% (canopy bulk density) of the observed variation. Inclusion of the fitted models in fire management decision-making can provide a decision support system for assessing the potential crown fire of different silvicultural alternatives.

INTRODUCTION: The differences in the prevalence of obesity between the various regions of Spain, partly attributed to socioeconomic differences, may influence the approach to this disease. The aim of this study was to compare differences in attitudes, perception, and barriers to the treatment of obesity between people with obesity (PwO) and health care professionals (HCPs), between the different regions of Spain. METHODS: Sub-analysis of the ACTION-IO Spain study, which included 1,500 PwO and 306 HCP, was performed to identify differences in PwQ and HCPs belonging to regions with high prevalence of obesity (>16%, n = 9 regions, high prevalence of obesity [HPO] group) and low prevalence of obesity (<16%, n = 8 regions, low prevalence of obesity [LPO] group) (self-reported data), according to the 2017 National Health Survey of Spain. STATISTICS: comparison of proportions (χ2). RESULTS: A total of 746 PwO belonged to HPO and 754 to LPO group. The PwO in HPO group were younger, had lower income, a lower level of higher education, higher unemployment rate, and fewer comorbidities. Obesity was considered a chronic disease to a higher extent in HPO compared to LPO group (62 vs. 56%), but this difference was not statistically significant. The PwO in HPO group discussed less with the HCPs about their excess weight (57 vs. 70%), did not feel motivated to lose weight in a higher percentage (26 vs. 18%), and felt less emotionally supported (16 vs. 24%). In HPO group, the preference for unhealthy food (51 vs. 36%), and the costs of healthy eating, anti-obesity drugs and bariatric surgery were perceived barriers to losing weight. A higher proportion of PwO in HPO group considered that exercise (58 vs. 40%) was more effective for achieving weight loss. In contrast, LPO group considered diet more effective (48 vs. 32%). HCPs in HPO group felt more motivated to treat obesity (83 vs. 68%) and a higher proportion (14 vs. 5%) identified the economic burden as one of the main reasons why PwO do not start conversations to lose weight. CONCLUSIONS: There is less concern and conversation about excess weight in PwO in regions with a higher prevalence of obesity, with socioeconomic limitations being one of the main perceived barriers to treatment.

BACKGROUND: Outcomes of bariatric surgery (BS) in patients with schizophrenia are poorly understood. We aimed to analyze the effects of BS in patients with schizophrenia (SZ) or schizoaffective disorder (SZA). METHODS: This was a multicenter, retrospective case-control study in patients with SZ or SZA who had undergone BS in seven public referral hospitals in Spain. Controls without psychiatric comorbidity were selected in a 1:4 ratio. Detailed clinical and biochemical data were collected preoperatively and at 12, 24, 36, 48, and 60 months after BS. RESULTS: Twenty patients with SZ (n = 15; 75%) or SZA (n = 5; 25%) and 80 matched controls were studied. There were no differences between patients and controls concerning the evolution of the percentage of total weight loss. The remission rate of the main comorbidities was similar between groups except for hypertension, which was lower in patients with a psychotic disorder from year 3. There were no mortalities within 30 days of surgery in either group. The psychiatric medication burden did not change during follow-up. CONCLUSIONS: BS is safe and effective in carefully selected patients with SZ. The course of the psychiatric disease does not seem to be worsened by the procedure.

Introduction: Hypoaldosteronism is characterized by hyperkalemia, and/or hypovolemic hyponatremia (HH), often accompanied by metabolic acidosis. HH is typical of hypoaldosteronism, whereas euvolemic hyponatremia (EH) is not. The purpose of the current study is to describe the characteristics of hyponatremia in hypoaldosteronism and elucidate whether EH can be considered part of the disease's spectrum. Methods: In a hypoaldosteronism cohort, we analyzed the factors associated with hyponatremia, comparing the characteristics of EH and HH and their associated factors. Correlation analyses of mineralocorticoid biomarkers, such as the transtubular potassium gradient (TTKG), the urinary Na+/K+ ratio (UNa+/UK+) with serum, and urinary electrolytes were performed in both types of hyponatremia. Results: Of 112 hypoaldosteronism episodes, 77.7% were ≥65 years old, 44.6% were women, and 80 (71.4%) had hyponatremia. Hyponatremia was negatively associated with the presence of chronic kidney disease, and positively with a hypovolemic state, malnutrition, a prior history of hyponatremia, and glucocorticoid therapy. HH: 61/80 and EH: 19/80 episodes. HH was associated with an age ≥65 years and the use of diuretics, as well as factors related to an aldosterone deficit and/or mineralocorticoid resistance. In HH but not in EH, urinary potassium was correlated with the TTKG, and urinary sodium with both the TTKG and the UNa+/UK+. Conclusion: Both HH and EH can be observed in hypoaldosteronism. However, only the former would be related to insufficient mineralocorticoid activity. Significance statement: Isolated hypoaldosteronism is a poorly understood and underdiagnosed endocrinological disorder, classically recognized only when hyperkalemia is present. The development of hypovolemic hyponatremia, however, is also easily explained by the physiopathology of the disorder. The current study addresses the features of hyponatremia when found in the context of mineralocorticoid insufficiency, and confirms an association between hypovolemic hyponatremia and isolated hypoaldosteronism. Thus, the clinical spectrum of hypoaldosteronism is extended to include hypovolemic hyponatremia as a frequent manifestation of the disorder.
ABSTRACT
BACKGROUND: Bariatric surgery (BS) may decrease the risk of these obesity-related complications; however, due to its effect on nutrient intake and absorption, it can also have adverse consequences on maternal and foetal health. The aim of this study is to describe the evolution of electrolytes and trace elements serum levels throughout pregnancy after BS, according to the surgical technique and to evaluate the effect of nutritional deficiencies on the risk of maternal-foetal complications. METHODS: This is a retrospective observational study of the clinical evolution and maternal-foetal complications in a group of women with pregnancies that occurred after BS. Clinical evolution during pregnancy, body weight, and plasma electrolytes, vitamins, and trace elements, as well as their influence on maternal-foetal outcomes were evaluated. Composite neonatal variable (CNV) was defined to evaluate unfavourable foetal outcome. Published reference values for micronutrients during pregnancy have been used. RESULTS: The study includes data on 164 singleton pregnancies in 91 women. A hundred and twenty-seven pregnancies got to full term. The average birth weight was 2966 (546) g., 26.8% < P10 and 13.8% < P3 of a reference population. New-born of gestations after malabsorptive bariatric surgery had a higher risk of having a percentile of birth weight < P3. Plasma electrolytes, trace elements and vitamins throughout pregnancy showed differences depending on the surgical technique, with lower haemoglobin, ferritin, calcium, zinc, copper, vitamin A and vitamin E in the malabsorptive techniques. A high percentage of deficiency was observed, especially in the third trimester (Hb < 11â¯g/dl: 31.8%; ferritin < 30â¯mg/ml: 85.7%; zinc < 50⯵g/dl: 32.4%, vitamin D < 30â¯ng/ml: 75.5% and < 20â¯ng/ml: 53.3%). A decreased plasma copper in the first trimester or zinc in the third trimester were associated with a lower percentile of new-born birth weight. A higher risk of CNV was observed in predominant malabsorptive BS and in pregnancies that had presented at least one vitamin D level lower than 20â¯ng/ml throughout pregnancy (30.4% vs. 7.1%, p=0.018). CONCLUSIONS: Trace elements and vitamin deficiencies are common in pregnant women after bariatric surgery, especially of iron, zinc, and vitamin D. These deficiencies might negatively affect foetal development. Further studies are needed to better define the role of micronutrients in maternal-foetal health after bariatric surgery.

As a respiratory virus, COVID-19 propagates based on human-to-human interactions with positive COVID-19 cases. The temporal evolution of new COVID-19 infections depends on the existing number of COVID-19 infections and the people's mobility. This article proposes a new model to predict upcoming COVID-19 incidence values that combines both current and near-past incidence values together with mobility data. The model is applied to the city of Madrid (Spain). The city is divided into districts. The weekly COVID-19 incidence data per district is used jointly with a mobility estimation based on the number of rides reported by the bike-sharing service in the city of Madrid (BiciMAD). The model employs a Long Short-Term Memory (LSTM) Recurrent Neural Network (RNN) to detect temporal patterns for COVID-19 infections and mobility data, and combines the output of the LSTM layers into a dense layer that can learn the spatial patterns (the spread of the virus between districts). A baseline model that employs a similar RNN but only based on the COVID-19 confirmed cases with no mobility data is presented and used to estimate the model gain when adding mobility data. The results show that using the bike-sharing mobility estimation the proposed model increases the accuracy by 11.7% compared with the baseline model.
ABSTRACT
Bariatric surgery is increasingly used in women of childbearing age due to the rising prevalence of obesity and the effectiveness and availability of this treatment. Pregnancy in women with previous bariatric surgery deserves special attention. Weight loss induced by surgery reduces the risks that obesity poses to pregnancy. But on the other hand, decreased intake and malabsorption may increase the risk of malnutrition and micronutrient deficiency and negatively affect maternal and foetal health. The aim of this narrative review is to provide an updated analysis of the impact of different bariatric surgery techniques on mineral and micronutrient nutritional status during pregnancy and the possible effect on maternal-foetal health.
ABSTRACT
BACKGROUND: Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) is a simplification of the duodenal switch (DS) in which the alimentary limb is eliminated, and the common channel is lengthened from 200 to 300 cm. Short-term results have demonstrated that SADI-S is safe and reproducible and that weight loss and comorbidities resolution are comparable to biliopancreatic diversion or DS. OBJECTIVE: To analyze the long-term outcomes of SADI-S. METHODS: From May 2007 to December 2015, 164 patients were consecutively submitted to a one-step SADI-S. The mean age was 47 years, and the mean body mass index (BMI) was 45.8 kg/m2. A total of 101 patients had type 2 diabetes, 91 arterial hypertension, 81 obstructive apnea, and 118 dyslipidemia. Limb length was 200 cm in 50 cases, 250 cm in 99, and 300 cm in 15. RESULTS: There was no mortality. One patient had a gastric leak, and 2 patients had an anastomotic leak. A total of 25% of the patients were lost to follow-up at 10 years. Excess weight loss and total weight loss were 87% and 38% at 5 years and 80% and 34% at 10 years. A total of 12 patients were submitted to revisional surgery for hypoproteinemia. Preoperatively 41 diabetics were under insulin treatment; at 5 years, 7 remained with insulin and 12 at 10 years. Mean glycemia was 104 mg/dL at 5 years and 118 mg/dL at 10 years. Mean HbA1c was 5.51% at 5 years and 5.86 at 10 years. CONCLUSION: In the long term, SADI-S offers satisfactory weight loss and comorbidities resolution.

Introduction: Hypoaldosteronism can be congenital or acquired, isolated or part of primary adrenal insufficiency, and caused by an aldosterone deficit, resistance, or a combination of both. Reduced mineralocorticoid action can induce a decrease in urine K+ and H+ excretion and an increase in urine Na+ excretion, leading to hyperkalemia, and/or hyponatremia, often combined with metabolic acidosis. We aimed to characterize the clinical manifestations of hypoaldosteronism, and their associated factors. Methods: Retrospective analysis of 112 episodes of hypoaldosteronism diagnosed in 86 adult patients from 2012-2019 by the Endocrinology and Nutrition Department of a tertiary hospital. The frequency of hyperkalemia, hypovolemic hyponatremia (HH) and metabolic acidosis (MA), and their associated factors were evaluated. Results: Patients had a median age of 77 [65 - 84], 55.4% were male. 94.6% cases showed hyperkalemia, 54.5% HH, and 60.3% MA. The mean serum K+ of all cases was 5.4 ± 0.5 mmol/L, Na+: 132.1 ± 6.3 mmol/L, HCO3: 22.6 ± 3.3 mmol/L. Hypoaldosteronism was isolated in the majority of cases: only 6/112 (5%) had primary adrenal insufficiency. Hypovolemia was associated with hyponatremia and a more florid clinical presentation. HH was associated with a combined presence of aldosterone-lowering and mineralocorticoid resistance factors. MA was associated with the presence of mineralocorticoid resistance factors. Conclusions: Hypoaldosteronism in adult endocrinological clinical practice is primarily isolated, and acquired. It predisposes not only to the development of hyperkalemia and MA, but also to that of HH. Hypoaldosteronism must be considered in the differential diagnosis of HH with urinary sodium wasting.

INTRODUCTION: COVID-19 disease has become a priority for our healthcare system. The resident physicians training in endocrinology and nutrition (E&N residents) have been integrated into the COVID-19 teams. This study has been designed with the aim of analysing the educational, occupational and health impact on E&N residents. MATERIAL AND METHODS: Cross-sectional observational study via a web survey, aimed at E&N residents who are members of the SEEN, carried out in November 2020. The following data were analysed: demographic variables, number of beds in the training hospital, alteration of rotations, integration in COVID-19 teams, participation in telemedicine, scientific activity and impact on physical and emotional health. RESULTS: 87 responses were obtained (27% of all E&N residents), 67.8% women, 28.1 ± 1.8 years, 60% 4th year E&N residents. 84% participated in COVID-19 teams and 93% in the telemedicine consultations of their service. Most have had their rotations interrupted. 97.7% have participated in scientific meetings or virtual congresses and a third of them have collaborated in scientific work on COVID-19 in relation to endocrinology and nutrition. Overall, 75.8% think the pandemic has affected their mood a lot or quite a lot, and 73.8% think that the pandemic has negatively impacted their training. CONCLUSIONS: The SARS-CoV-2 pandemic has compromised the training, work activity and health of E&N residents. They have been integrated both in COVID-19 teams and in the restructured activity of their departments. However, they have managed to continue their training in virtual format and have participated in scientific work.
