Trade-offs between bycatch and target catches in static versus dynamic fishery closures.

While there have been recent improvements in reducing bycatch in many fisheries, bycatch remains a threat for numerous species around the globe. Static spatial and temporal closures are used in many places as a tool to reduce bycatch. However, their effectiveness in achieving this goal is uncertain, particularly for highly mobile species. We evaluated evidence for the effects of temporal, static, and dynamic area closures on the bycatch and target catch of 15 fisheries around the world. Assuming perfect knowledge of where the catch and bycatch occurs and a closure of 30% of the fishing area, we found that dynamic area closures could reduce bycatch by an average of 57% without sacrificing catch of target species, compared to 16% reductions in bycatch achievable by static closures. The degree of bycatch reduction achievable for a certain quantity of target catch was related to the correlation in space and time between target and bycatch species. If the correlation was high, it was harder to find an area to reduce bycatch without sacrificing catch of target species. If the goal of spatial closures is to reduce bycatch, our results suggest that dynamic management provides substantially better outcomes than classic static marine area closures. The use of dynamic ocean management might be difficult to implement and enforce in many regions. Nevertheless, dynamic approaches will be increasingly valuable as climate change drives species and fisheries into new habitats or extended ranges, altering species-fishery interactions and underscoring the need for more responsive and flexible regulatory mechanisms.

The Epidemic of Internalizing Problems Among Latinx Adolescents Before and During the Coronavirus 2019 Pandemic.

OBJECTIVE: Latinx youth exhibit disproportionately higher internalizing symptoms than their peers from other racial/ethnic groups. This study compares depression and anxiety symptoms between referred students of Latinx and non-Latinx backgrounds before and during the COVID-19 pandemic and examines key determinants within the Latinx sample. METHOD: Data are analyzed from four academic years - two before and two during the pandemic - from 1220 5th through 8th grade students (Mage = 12.1; 59.6% female; 59.9% Latinx or mixed-Latinx) referred for services across 59 Chicago Public School District (CPS) elementary schools. Using the Children's Depression Inventory (CDI) and the Revised Child Anxiety and Depression Scale (RCADS), mean scores and risk levels for depression, social anxiety, and generalized anxiety are examined. RESULTS: Higher internalizing risk and comorbidity rates were found in the second year of the pandemic, compared to pre-pandemic levels. Latinx students reported higher depression, social anxiety, and generalized anxiety symptoms than non-Latinx students. During the pandemic, more Latinx students were classified as having comorbid depression and anxiety, and scored in the clinical range for depression, generalized anxiety, and social anxiety than non-Latinx students. Within the Latinx sample, girls and gender non-conforming students reported the highest maladjustment. CONCLUSIONS: Results highlight the pressing need to examine the long-term impact of COVID-19 on the mental health of Latinx children and adolescents, and to address their internalizing problems.

Complexity of needs in amyotrophic lateral sclerosis (ALS) patients using the ENP-E scale in the north-eastern region of Spain.

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.

Predictive capacity of FRAX in a spanish region with a hip fracture rate close to the national mean.

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.

Global longitudinal strain assessment of cardiac function and extravascular lung water formation after diving using semi-closed circuit rebreather.

PURPOSE: The aim of the present investigation is to study the relationship of ventricular global longitudinal strain (GLS) and ultrasound lung comets (ULC) formation to establish a link between extravascular pulmonary water formation and cardiac contractile dysfunction. METHODS: This is a prospective observational study including 14 active military divers. The subjects performed two sea dives of 120 min each with a semi-closed SCUBA circuit at 10 m depth. Divers were examined at baseline, 15 min (D1) and 60 min (D2) after diving. The evaluation included pulmonary and cardiac echography (including speckle tracking techniques). Blood samples were drawn at baseline and after diving, assessing hs-TnT and Endothelin-1. RESULTS: ULC were detected in 9 (64.2%) and 8 (57.1%) of the subjects after D1 and D2 respectively. No differences were found in right and left ventricular GLS after both immersions (RV: Baseline: - 17.9 4.9 vs. D1: - 17.2 6.5 and D2: - 16.7 5.8 s-1; p = 0.757 and p = 0.529; LV: Baseline: - 17.0 2.3 vs. D1: - 17.4 2.1 and D2: - 16.9 2.2 s-1; p = 0.546 and p = 0.783). However, a decrease in atrial longitudinal strain parameters have been detected after diving (RA: Baseline: 35.5 9.2 vs. D1: 30.3 12.8 and D2: 30.7 13.0 s-1; p = 0.088 and p = 0.063; LA: Baseline: 39.0 10.0 vs. D1: 31.6 6.1 and D2: 32.4 10.6 s-1; p = 0.019 and p = 0.054). CONCLUSION: In the present study, no ventricular contractile dysfunction was observed. However, increase pulmonary vasoconstriction markers were present after diving.

Changes in Serum Creatinine Levels Can Help Distinguish Hypovolemic from Euvolemic Hyponatremia.

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.

The first modified Delphi consensus statement on sleeve gastrectomy.

INTRODUCTION: Sleeve gastrectomy (SG) is the commonest bariatric procedure worldwide. Yet there is significant variation in practice concerning its various aspects. This paper report results from the first modified Delphi consensus-building exercise on SG. METHODS: We established a committee of 54 globally recognized opinion makers in this field. The committee agreed to vote on several statements concerning SG. An agreement or disagreement amongst ≥ 70.0% experts was construed as a consensus. RESULTS: The committee achieved a consensus of agreement (n = 71) or disagreement (n = 7) for 78 out of 97 proposed statements after two rounds of voting. The committee agreed with 96.3% consensus that the characterization of SG as a purely restrictive procedure was inaccurate and there was 88.7% consensus that SG was not a suitable standalone, primary, surgical weight loss option for patients with Barrett's esophagus (BE) without dysplasia. There was an overwhelming consensus of 92.5% that the sleeve should be fashioned over an orogastric tube of 36-40 Fr and a 90.7% consensus that surgeons should stay at least 1 cm away from the angle of His. Remarkably, the committee agreed with 81.1% consensus that SG patients should undergo a screening endoscopy every 5 years after surgery to screen for BE. CONCLUSION: A multinational team of experts achieved consensus on several aspects of SG. The findings of this exercise should help improve the outcomes of SG, the commonest bariatric procedure worldwide, and guide future research on this topic.

Outcomes of Adrenalectomy and the Aldosteronoma Resolution Score in the Black and Hispanic Population.

BACKGROUND: Outcomes after adrenalectomy in patients with primary aldosteronism (PA) are variable. The aldosteronoma resolution score (ARS) uses preoperative variables to calculate a score that identifies those patients that are more likely to have resolution of hypertension after adrenalectomy. We aim to determine the efficacy of adrenalectomy and whether the ARS accurately predicts clinical success in a Black and Hispanic population. METHODS: We reviewed patients who underwent adrenalectomy for PA from 2004 to 2018 at two academic centers treating primarily Hispanic and Black patients. Postoperative outcomes were evaluated based on the primary aldosteronism surgical outcome consensus criterion. Retrospectively, the accuracy of ARS was determined by a receiver operating characteristic curve and the area under the curve (AUC). RESULTS: Forty-three Hispanic and 10 Black patients underwent adrenalectomy for PA. Twenty-two patients (41.5%) had complete clinical success. Variables associated with complete clinical success in the univariate analysis were female gender (p = 0.026), younger age (p = 0.001), lower preoperative aldosterone (p = 0.035), lower preoperative systolic blood pressure (p = 0.001), fewer number of preoperative antihypertensive medications (p = 0.007) and a higher ARS (p = 0.003). On multivariate analysis, only fewer number of preoperative antihypertensive medications was independently associated with complete clinical success (p = 0.026). The AUC of the ARS was 0.746. CONCLUSION: The rate of clinical success from adrenalectomy is good for Hispanic and Black patients with PA. Our analysis shows that the ARS is an accurate test of clinical success in Hispanic and Black patients. The ARS may be utilized preoperatively to frame expectations after adrenalectomy in these populations.

Endocrine hypertension secondary to adrenal tumors: clinical course and predictive factors of clinical remission.

PURPOSE: Endocrinopathies constitute ~ 10% of secondary hypertension (SH) etiologies. Primary aldosteronism, pheochromocytoma (PHEO), and Cushing's syndrome are common causes. Early identification and treatment result in resolution/improvement of SH. The aim of this study was to characterize the clinical course, outcomes, and remission-associated prognostic factors of SH related to adrenal tumors. METHODS: Retrospective cohort study including patients with SH who underwent adrenalectomy from 2000 to 2019. Postoperative outcomes were analyzed. Remission was defined as normalization of blood pressure without drug use. RESULTS: Eighty-three patients with SH were included. Mean ± SD age was 38.8 ± 14.2 years and 75.9% were women. Diagnosis was PHEO in 35 patients (42.2%), aldosteronoma (APA) in 28 (33.7%), cortisol producing adenoma (CPA) in 16 (19.3%), and ACTH-dependent Cushing's in 4 (4.8%). Laparoscopic adrenalectomy was performed in 81 (97.6%) patients. Mean ± SD follow-up was 57.4 ± 49.6 months (range 1-232). Surgical morbidity occurred in 7.2% of patients and there was no mortality. Remission of SH occurred in 61(73.5%): 100% of ACTH-dependent Cushing's, 85.7% of PHEO, 68.8% of CPA, and 57.1% of APA. Biochemical phenotype and the combination of larger tumor size, number of antihypertensive drugs, male gender, older age, obesity, and preoperative SH for more than 5 years were associated with less likely clinical remission in patients with APA (p = 0.004), CPA (p < 0.0001), and PHEO (p < 0.0001). CONCLUSION: SH remission rates are 57-100% after adrenalectomy. Several prognostic factors could be used to predict SH control. Adrenalectomy provides good clinical outcome and must be considered a treatment option in all surgical candidates.

Clinical factors associated with early and persistent hypocalcaemia after parathyroidectomy in patients on dialysis with severe hyperparathyroidism.

AIM: Severe hypocalcaemia following parathyroidectomy for secondary or tertiary hyperparathyroidism (SHPT/THPT) is scarcely studied. We aimed to describe and identify risk factors for early and persistent hypocalcaemia after parathyroidectomy. METHODS: Retrospective pair-matched cohort study. We assessed 87 dialysis patients with SHPT (n = 73) or THPT (n = 14) paired with 146 subjects with primary hyperparathyroidism (PHPT) who underwent parathyroidectomy and were followed for 12 months. Early severe hypocalcaemia was defined as a free Ca ≤0.8 mmol/L [3.2 mg/dl] or corrected Ca ≤1.87 mmol/L [7.5 mg/dl] within 48 h. After parathyroidectomy and persistent hypocalcaemia, as an elemental Ca intake >3.0 g/day to achieve corrected Ca >2 mmol/L [8.0 mg/dl]. RESULTS: Early severe hypocalcaemia occurred in 77% (67/87) versus 6.8% (10/146) of subjects with SHPT/THPT and PHPT, respectively (p < .001). In SHPT/THPT cases, persistent hypocalcaemia occurred in 77% (49/64) and 64% (35/54) after 6 and 12 months of parathyroidectomy, respectively. In PHPT cases, persistent hypocalcaemia occurred in 6.8% (10/146) after 4-12 months of parathyroidectomy. Preoperative serum alkaline phosphatase (ALP) was the only risk factor associated to early severe hypocalcaemia (OR 7.3, 95% C.I. 1.7-10.9, p = .006) and persistent hypocalcaemia (OR 7.1, 95% C.I: 2.1-14.2, p = .011). Subjects with persistently low intact parathormone (iPTH) (<5.3 pmol/L [50 ng/ml]), suggestive of adynamic bone disease) showed higher Ca increases and less oral calcium requirements compared to those who progressively increased iPTH after parathyroidectomy. CONCLUSION: Early and persistent hypocalcaemia after parathyroidectomy in severe HPT were a common event associated directly to preoperative ALP levels. Subjects with persistently low postoperative iPTH normalized serum Ca more frequently after 1 year of follow up.

Health literacy of patients on oral anticoagulation treatment- individual and social determinants and effect on health and treatment outcomes.

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.

Urban soils as a spatial indicator of quality for urban socio-ecological systems.

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.

Mid-Term and Long-Term Impact of Permanent Hypoparathyroidism After Total Thyroidectomy.

BACKGROUND: Permanent hypoparathyroidism (PH) is the most frequent long-term complication after total thyroidectomy. PH is related to many short-term and long-term complications, including clinical manifestations of hypocalcemia, hypercalcemia due to overtreatment, hyperphosphatemia, gastrointestinal, neuropsychiatric symptoms, decrease in renal function and infectious complications. The aim of this study was to identify the most frequent effects of PH and its associated risk factors. METHODS: We performed a retrospective analysis of a single institutional series of patients who developed PH after total thyroidectomy between 2000 and 2016. PH was defined as hypoparathormonemia (≤12 pg/mL) or the need for calcium/vitamin D supplementation to achieve normal calcium levels for more than 12 months. Descriptive and inferential statistics were employed based on the natural scaling of each included variable. RESULTS: Thirty-nine patients fulfilled the criteria for PH. Mean ± SD age was 46.26 ± 13.4 years; 6 (15.4%) were males and 33 (84.6%) females. Mean follow-up was 6.13 ± 3.25 years. Mean calcium carbonate supplementation doses per day were 18.95 ± 17.5 g and 21.4 ± 19.3 g at 1 year and last follow-up, respectively. Hypocalcemic crisis was the most common complication (66.7%), followed by neuropsychiatric (38.5%) and gastrointestinal symptoms (33.3%). Ten patients showed a decrease in renal function (eGFR drop ≥25%) and 4 developed chronic kidney disease. The amount of calcium supplementation was the most relevant related risk factor. CONCLUSIONS: PH is associated with multiple complications, including renal function impairment, gastrointestinal, neuropsychiatric and infectious complications. Lower calcium supplementation doses are related to lower complications rates.

Effect of Roux-en-Y gastric surgery on ciprofloxacin pharmacokinetics: an obvious effect?

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.

Hypoparathyroidism After Total Thyroidectomy: Importance of the Intraoperative Management of the Parathyroid Glands.

BACKGROUND: Total thyroidectomy is the most common surgical procedure for the treatment of thyroid diseases. Postoperative hypocalcemia/hypoparathyroidism is the most frequent complication after total thyroidectomy. The aim of this study was to evaluate the rate of postoperative hypocalcemia and permanent hypoparathyroidism after total thyroidectomy in order to identify potential risk factors and to evaluate the impact of parathyroid autotransplantation. PATIENTS AND METHODS: We performed a retrospective analysis of 1018 patients who underwent total thyroidectomy at our institution between 2000 and 2016. Medical records were reviewed to analyze patient features, clinical presentation, management and postoperative complications. Descriptive and inferential statistics were employed based on the natural scaling of each included variable. Statistical significance was set at p ≤ 0.05. RESULTS: Mean ± SD age was 46.79 ± 15.9 years; 112 (11.7%) were males and 844 (88.3%) females. A total of 642 (67.2%) patients underwent surgery for malignant disease. The rate of postoperative hypocalcemia, transient, protracted and permanent hypoparathyroidism was 32.8%, 14.43%, 18.4% and 3.9%, respectively. Permanent hypoparathyroidism was significantly associated with the number of parathyroid glands remaining in situ (4 glands: 2.5%, 3 glands: 3.8%, 1-2 glands: 13.3%; p ˂ 0.0001) [OR for 1-2 glands in situ = 5.32, CI 95% 2.61-10.82]. Other risk factors related to permanent hypoparathyroidism were obesity (OR 3.56, CI 95% 1.79-7.07), concomitant level VI lymph node dissection (OR 3.04, CI 95% 1.46-6.37) and incidental parathyroidectomy without autotransplantation (OR 3.6, CI 95% 1.85-7.02). CONCLUSIONS: Identification and in situ preservation of at least three parathyroid glands were associated with a lower rate of postoperative hypocalcemia (30.4%) and permanent postoperative hypoparathyroidism (2.79%).

Recurrent Papillary Thyroid Carcinoma to the Cervical Lymph Nodes: Outcomes of Compartment-Oriented Lymph Node Resection.

INTRODUCTION: Recurrence of papillary thyroid carcinoma after initial treatment is challenging. Surgical reintervention is recommended, but cure after surgery in uncertain and surgical morbidity may be high. This study evaluates the effect of compartment-oriented lymph node dissection (LND) on clinical and biochemical cure rate as well as the related complications. PATIENTS AND METHODS: All patients who underwent LND for recurrent papillary thyroid carcinoma between 2000 and 2015 were included. Demography, the extent of the initial surgery, usage of 131I, the pattern of recurrence, diagnosis, details of the surgical reintervention, histological findings, surgical morbidity, and clinical and biochemical outcomes were analyzed. RESULTS: There were 11 (12.7%) males and 75 (87.2%) females with a mean age of 42.8 ± 14.6 years. Seventy-seven patients had undergone total thyroidectomy and in 67 (77.9%) some type of LN resection. In 76 (88.3%), 131I was administered after the initial surgery. We localized suspicious lymph nodes by US in all patients, and metastases were documented before surgery by FNA in 63. Seven (8.13%) patients underwent central LND, 63 (73.2%) lateral LND and 16 (18.6%) both, central and lateral LND. Major complications occurred in 6 patients (6.9%). Sixty-two (72.0%) patients received 131I after surgery. A second surgical re-exploration was performed in 30 (34.8%) patients, and 7 patients required 3 or more additional LND. In a mean follow-up of 59.4 ± 39 months, 51 (59.3%) patients are clinically, radiologically and biochemically free of disease. CONCLUSIONS: In this series, compartment-oriented lymph node resection of recurrent papillary thyroid carcinoma leads to a final clinical and biochemical disease-free status of 59.3% with 6.9% of major complications.

Motivations, Beliefs, and Expectations of Spanish Nurses Planning Migration for Economic Reasons: A Cross-Sectional, Web-Based Survey.

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.

Absence of an Additional Metabolic Effect of Body Contour Surgery in Patients With Massive Weight Loss After Laparoscopic Roux-En-Y Gastric Bypass.

INTRODUCTION: Body contour surgery (BCS) is a combination of soft tissue resections that have proven to be an effective treatment for the aesthetic and functional problems related to massive weight loss (MWL). There are no studies analyzing the metabolic effect of large volume adipose tissue flap resection in patients with MWL after bariatric surgery. METHODS: This study was a retrospective review of adults who underwent BCS after gastric bypass. Preoperative clinical and laboratory data were compared with 1- and 2-year postoperative follow-up. RESULTS: A total of 62 patients with a mean age of 41 years were analyzed. Seventy-nine percent of them were women. Most procedures included abdominal flap resection alone or in combination with other areas. Mean resected tissue weight was 6.2 kg. We found that weight and body mass index (BMI) were lower 1 year after BCS (P < 0.05), but this was not maintained after 2 years. There were no differences for systolic or diastolic blood pressure, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, or fasting glucose after 1 and 2 years of the BCS. A subgroup analysis showed that the transient weight and BMI improvement was only apparent 1 year after BCS in those patients with flap resections more than 8 kg. CONCLUSIONS: There are no differences in blood pressure, total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, or fasting glucose 1 and 2 years after BCS in patients who experienced MWL after gastric bypass. Although weight and BMI were transiently lower in those patients with tissue flap resections more than 8 kg, this effect disappeared after 2 years.
