Programa de entrenamiento de parotidectomía en modelo cadavérico perfundido

Introducción: La parotidectomía es una cirugía infrecuente y técnicamente compleja determinada por la dificultad de disección del nervio facial, cuya lesión produce alto grado de morbilidad en los pacientes. Los modelos de simulación animales no logran reproducir las características de la anatomía regional, por lo que se hace necesario explorar otras alternativas para el entrenamiento de estas habilidades. Nuestro objetivo es evaluar un programa de entrenamiento de técnicas de parotidectomía en un modelo cadavé-rico perfundido. Métodos: Se diseñó un programa educacional de Kern de entrenamiento de residentes de Cirugía de Cabeza y Cuello para la realización de parotidectomía total en un modelo cadavérico perfundido. La evaluación se realizó mediante el modelo de Kirkpatrick, en los niveles 1 (reacción), 2A (cambio de actitudes) y 2B (adquisición de conocimientos y habilidades). Resultados: Se elaboró un programa teórico-práctico basado en cátedras y simulación de alta fidelidad. En su mayoría los participantes: recomendarían el curso (Nivel 1); tuvieron mayor motivación para el aprendizaje (Nivel 2) y presentaron mejores indicadores sobre conocimientos, habilidades y percepción de mejoría de sus competencias (Nivel 2B). Conclusión: La utilización de un programa de parotidectomía simulado en un modelo de alta fidelidad basado en modelos cadavéricos humanos perfundidos es una alternativa que mejora la calidad de entrenamiento y es útil y factible para el aprendizaje de técnicas de parotidectomía en residentes de Cirugía de Cabeza y Cuello.

Introduction: The parotidectomy is an infrequent and technically complex surgery due to a difficult dissection that may affect the facial nerve, generating high degree of morbidity in patients. Animal simulation models may not reproduce the human characteristics of cervical anatomy. Therefore, it is necessary to explore other alternatives for training dissection skills. Our objective is to evaluate a parotidectomy's techniques training program in a perfused cadaveric model. Methods: A Kern educational program was designed to train Head and Neck Surgery residents to perform total parotidectomy in a perfused cadaveric model. The evaluation was performed using Kirkpatrick model, at levels 1 (reaction), 2A (change of attitudes) and 2B (acquisition of knowledge and skills). Results: A theoretical-practical program based on lectures and high-fidelity simulation was developed. Most of the participants would recommend the course (Level 1); had greater motivation for learning (Level 2) and showed better indicators of knowledge, skills and perception of improvement in their competencies (Level 2B). Conclusion: The use of a simulated parotidectomy program in a high-fidelity model based on perfused human cadaveric models is an alternative that improves the quality of training and is useful and feasible for learning parotidectomy techniques in residents of Head and Head Surgery.

Introduction: >Enhanced recovery after Surgery (ERAS) or STAR are the tools that have proven to be more effective in perioperative management. Objective: Primary objective is to describe the results obtained regarding complications, hospital stay and readmissions after 2 years of implementation of the STAR. Secondary objective is to describe protocol adherence. Materials and Method: Non-concurrent retrospective cohort study, in patients with elective colorectal surgery. From January to December 2016 non-protocolized management (non-STAR group), August 2018 to July 2020 STAR protocol management (STAR group). Registration of data like the demographic variables, adherence to protocol, complications and readmissions. Continuous variables (quartiles, mean and SD), t-Student test, Wilcoxon test, categorical variables (frequencies and percentages), Fisher test and propensity score (PS) were used. Results: 239 patients; non-STAR group 85 patients (35.5%), STAR group 154 (64.5%), male 111 patients (43 non-STAR p = 0.347). Average age non-STAR 64.2 (SD 14.7) vs STAR 66.3 (SD 14.39) (p = 0.3147). Median non-STAR stays 5 days (average 6.9, SD 6.2) and for STAR 3 days (average 4.8 days, SD 4.4). Non-STAR had 22 complications (25.9%) vs 28 STAR (18.2%) p = 0.185. No-STAR 7 hospital readmissions vs 17 STAR (p = 0.654). Analysis of covariance (ANCOVA) for hospitalization days adjusted by gender, age and laparoscopic surgery shows 1.93 less hospitalization days (p = 0.005); Propensity Score (PS) shows reduced hospital stay in 1.92 days (p-value = 0.007). Discussion and Conclusión: The implementation of an advanced recovery protocol achieves a reduction of 2 days in the hospital stay of patients undergoing colorectal surgery, without increasing complications, mortality or readmissions.

Exploring the destiny and distribution of thiocyanate in the water-soil-plant system and the potential impacts on human health.

Endocrine disruptors like thiocyanate are some of the principal causes of chronic disorders worldwide. Prenatal and postnatal exposure to thiocyanate can interfere with normal neurological development in both fetuses and newborns. Currently, little information regarding thiocyanate levels and potential sources of exposure is available. In this study, we evaluated thiocyanate uptake and accumulation in chard and spinach grown under greenhouse conditions. Both chard and spinach are commonly used to produce baby foods. Three thiocyanate concentrations were compared: Control, T1 (30 ng mL-1), and T2 (70 ng mL-1). Thiocyanate accumulation depended on the concentration and exposure time. Chard was found to accumulate more thiocyanate than spinach, with leaf accumulation > stem accumulation (p < 0.0194) and maximum concentrations of 76 ng g-1 (control), 112 ng g-1, (T1), and 134 ng g-1 (T2). The estimated daily intake (EDI) of thiocyanate for chard and spinach (fresh) exceeded the subchronic reference dose of 200 ng-1 kg-1 day-1 and the chronic reference dose of 600 ng-1 kg-1 day-1. In addition, the EDI of thiocyanate for spinach in baby food exceeded twice the chronic reference dose in the vulnerable newborn-1 year age group. However, all EDIs were lower than the lowest observed adverse effect level (LOAEL) of 1.9 × 105 ng kg-1 day-1. Further studies are needed that increase our knowledge of thiocyanate levels and potential environmental sources to reduce opportunities for exposure, especially in vulnerable groups.

Accumulation and distribution of perchlorate in spinach and chard growing under greenhouse: Implications for food safety in baby foods commodities.

Very little information is available with regards to the bioavailability of perchlorate in spinach or chard used in the production of baby foods commodities. In the present study, the uptake and accumulation of perchlorate were compared under two different treatments (T1: 1 and T2: 10 mg L-1 ClO4-). Our results indicate that spinach has a higher capacity to accumulate perchlorate than chard (p < 0.0185). Concentrations of perchlorate in leaves, stems and roots (leaves > stem > roots) all gradually increased (p < 0.0001) as vegetable growing and treatment (T2 > T1). No significant differences were found between the control and T1. The daily intake for perchlorate (control) is below the proposed international standard, however, it was exceeded in T1 and T2. The results suggested that perchlorate is actively accumulate in high concentrations in vegetables used in the production of baby food commodities and the exposure of perchlorate via the food consumption (baby foods) was evaluated as not safe.

Electronic health records and patient registries in medical oncology departments in Spain

Purpose We aimed to evaluate the current situation of electronic health records (EHRs) and patient registries in the oncology departments of hospitals in Spain. Methods This was a cross-sectional study conducted from December 2018 to September 2019. The survey was designed ad hoc by the Outcomes Evaluation and Clinical Practice Section of the Spanish Society of Medical Oncology (SEOM) and was distributed to all head of medical oncology department members of SEOM. Results We invited 148 heads of oncology departments, and 81 (54.7%) questionnaires were completed, with representation from all 17 Spanish autonomous communities. Seventy-seven (95%) of the respondents had EHRs implemented at their hospitals; of them, over 80% considered EHRs to have a positive impact on work organization and clinical practice, and 73% considered that EHRs improve the quality of patient care. In contrast, 27 (35.1%) of these respondents felt that EHRs worsened the physician–patient relationship and conveyed an additional workload (n = 29; 37.6%). Several drawbacks in the implementation of EHRs were identified, including the limited inclusion of information on both outpatients and inpatients, information recorded in free text data fields, and the availability of specific informed consent. Forty-six (56.7%) respondents had patient registries where they recorded information from all patients seen in the department. Conclusion Our study indicates that EHRs are almost universally implemented in the hospitals surveyed and are considered to have a positive impact on work organization and clinical practice. However, EHRs currently have several drawbacks that limit their use for investigational purposes (AU)

Situation, challenges, and SEOM recommendations for the future of undergraduate education in Oncology in Spain.

PURPOSE: The Spanish Society of Medical Oncology (SEOM, for its Spanish acronym) would like to attest to the relevance of training in Oncology as part of the undergraduate education in Medicine program and issue recommendations to improve said training, with the aim of responding better to the challenges that cancer poses to our society. MATERIALS AND METHODS: The curricula of 42 schools of medicine were reviewed with interviews with at least one teaching medical oncologist from each faculty. The qualitative and opinion analysis was completed by means of an online questionnaire targeting lecturers, resident tutors, and residents in Medical Oncology (MO), enabling the detection of needs and areas for improvement at an organizational level and in terms of skill acquisition. RESULTS: While the number of medical schools with a specific, mandatory program in MO has grown by up to 90%, it has not been accompanied by an increase in independent programs. Instead, they largely consist of programs shared with other specialties (61% of the medical faculties). In most of the undergraduate education programs, Oncology contents are fragmented and approached from the perspective of each organ system. CONCLUSIONS: Despite the positive evolution in recent years, the heterogeneity in Oncology contents during undergraduate education training continues to be remarkable. Cross-sectional programs with an integral vision, taught in the final years of undergraduate medical education would be desirable. Among the recommendations for improvement of training in Medical Oncology, the SEOM proposes that updated, theoretical content be incorporated and clinical practice in Medical Oncology departments be promoted.

Hiperkalemia postoperatoria en síndrome de hueso hambriento post-paratiroidectomía por hiperparatiroidismo secundario en enfermedad renal crónica terminal / Hyperkalemia-associated hungry bone syndrome post-parathyroidectomy in end-stage denal disease

Introducción: El hiperparatiroidismo secundario (HPTS) es una complicación de la enfermedad renal crónica terminal (ERCT). A pesar de nuevas terapias médicas como calcimiméticos, en HPTS refractarios la paratiroidectomía (PTX) continúa siendo necesaria. Una complicación frecuente en estos pacientes posterior a la PTX es el síndrome de hueso hambriento (SHH), caracterizado por una profunda y prolongada hipocalcemia asociada a hipofosfatemia, secundaria a un excesivo aumento de su captación ósea. Una complicación menos descrita, pero con consecuencias graves e incluso fatales, es la hiperkalemia. El propósito de este trabajo consiste en enfatizar el riesgo de hiperkalemia por SHH a partir de un caso clínico, señalar los mecanismos fisiopatológicos, factores de riesgo y consideraciones terapéuticas. Caso clínico: Mujer de 35 años, con ERCT de causa desconocida, HPTS refractario con PTX total e implante de glándulas en antebrazo hace 9 años. Ingresa por recurrencia de HPTS. Cintigrama MIBI SPECT/CT® evidenció implante hiperfuncionante, indicándose PTX del injerto. Exámenes preoperatorios: calcemia 8.6 mg/dL, fosfatasas alcalinas 1115 UI/L (VN <100), PTH intacta (PTHi) 3509 pg/ml y kalemia 4.8 mEq/L. Biopsia: hiperplasia paratiroidea nodular. En postoperatorio inmediato presentó hiperkalemia de 7.1 mEq/L con cambios electrocardiográficos, requiriendo hemodiálisis de urgencia. Posteriormente desarrolló hipocalcemia, hipofosfatemia e hipomagnesemia, de difícil control. Discusión: El SHH post HPTS puede coexistir con hiperkalemia postoperatoria inmediata grave, incluso fatal si no se identifica y corrige a tiempo. El mecanismo fisiopatológico aún no está bien dilucidado. Varios factores pudieran intervenir, incluyendo aumento del metabolismo celular, traumatismo tisular, fármacos anestésicos, fluidos perioperatorios y flujo de iones transmembrana. El nivel de potasio previo a la cirugía, menor edad, género masculino, tiempo entre la última hemodiálisis y la cirugía, y duración de la PTX, son factores de riesgo para hiperkalemia postoperatoria. El conocimiento de esta grave complicación permitirá estar preparado para monitorizar y eventualmente tratar.

Introduction: Secondary Hyperparathyroidism (SHPT) is a complication of End-Stage Renal Disease (ESRD). Although new medical therapies (i.e.calcimimetics,) parathyroidectomy (PTX) continues to be necessary in refractory cases. A well-known complication after PTX is an entity called Hungry Bone Syndrome (HBS), characterized by deep and prolonged hypocalcemia associated with hypophosphatemia, secondary to an excessive increase in bone formation. A less reported complication, but with severe or even fatal consequences, is hyperkalemia. The purpose of this work consists of emphasizing the risk of hyperkalemia in HBS, reporting a clinical case that points out the physiopathological mechanisms, risk factors, and therapeutic considerations. Clinical case: 35-year-old woman with ESRD of unknown cause with refractory SHPT with total PTX and forearm gland grafts nine years ago. She presented SHPT recurrency. MIBI SPECT/CT® scan showed a hyperfunctioning implant, indicating graft PTX. Preoperative tests: calcemia 8.6 mg/dL, phosphatemia 7.3 mg/dL, alkaline phosphatases 1115 UI/L (VN<100), intact PTH (iPTH) 3509 pg/ml and kalemia 4.8 mEq/L. Biopsy: parathyroid nodular hyperplasia. In the immediate postoperative period, she presented hyperkalemia at 7.1 mEq/L with electrocardiographic changes, requiring emergency hemodialysis. Later she developed hypocalcemia, hypophosphatemia, and hypomagnesemia of difficult control. Discussion: HBS post PTX can coexist with severe immediate postoperative hyperkalemia, which can be even fatal if not detected and corrected. The physiopathological mechanism is still not entirely elucidated. Various factors could interfere, including an increase in cell metabolism, tissue traumatism, anesthetic drugs, intraoperative fluids, and transmembrane ion flow. Preoperative potassium levels, younger age, male gender, the time elapsed between last hemodialysis and surgery, and duration of PTX are risk factors for post-surgical hyperkalemia. Knowing this severe complication will allow the medical team to be prepared for monitoring and eventually treating it.

Motility and recovery of alpaca (Vicugna pacos) spermatozoa after centrifugation in a density gradient solution.

BACKGROUND: One of the factors limiting successful processing of alpaca (Vicugna pacos) semen is the viscosity of seminal plasma. The viscous nature of the collected ejaculate has hindered sperm cryopreservation as well as artificial insemination (AI) under field conditions. AIMS: The objective of this investigation was to evaluate recovery, motility, and plasma membrane integrity of alpaca spermatozoa after centrifugation in one of two different solutions at one of three different combinations of speed and time. METHODS: A total of 24 ejaculates was recovered from seven reproductively sound Huacaya males using a modified artificial vagina (AV) after training the animals for semen collection. A 2 × 3 factorial treatment arrangement was utilized for this study. Ejaculates were divided into fractions for centrifugation in one of two solutions (Tris extender or PureSperm®80 density gradient solution) at one of three combinations of speed and time (492 × g for 15 min, 1968 × g for 10 min, or 4448 × g for 7 min). The experiment was replicated eight times. RESULTS: Analysis revealed that centrifugation at 4448 × g for 7 min in PureSperm®80 provided a high recovery rate of spermatozoa with the highest sperm motility and functional integrity of plasma membrane post-centrifugation. Conclusion: Results suggest that adoption of this procedure (centrifugation at 4448 × g for 7 min in PureSperm®80) in the initial processing of alpaca ejaculates may enhance subsequent ability to use semen for AI and other assisted reproductive biotechnologies in this species.

Pretreatment neutrophil/lymphocyte, platelet/lymphocyte, lymphocyte/monocyte, and neutrophil/monocyte ratios and outcome in elderly breast cancer patients.

PURPOSE: Several studies have found an association between peripheral inflammatory cells and outcome. However, no study has explored their impact specifically in elderly patients. We have retrospectively examined pretreatment peripheral neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), and neutrophil/monocyte ratio (NMR) in 113 elderly breast cancer patients and correlated our findings with disease-free survival (DFS) and overall survival (OS). METHODS: All patients ≥ 65 years diagnosed from 2004 to 2018 with locally advanced breast cancer were included and classified as high vs low NLR, PLR, LMR, and NMR based on previously identified cutoffs. Estimated 1-, 3-, and 5-year DFS and OS were compared by Chi square analysis. RESULTS: Among 104 evaluable patients, only PLR was significantly associated with estimated 3-year DFS (85.1% vs 63.6%; P = 0.04) and OS (89.3% vs 68.1%; P = 0.03). Among 69 patients with three or more years of follow-up, PLR (P = 0.05), absolute lymphocyte count (ALC) (P = 0.01), polychemotherapy (P = 0.04), number of comorbidities (P = 0.02), polypharmacy (P = 0.005), and clinical stage (P = 0.03) were associated with 3-year DFS. Polypharmacy (OR 4.9; P = 0.02) and ALC (OR 4.6; P = 0.04) retained their significance in the multivariate analysis. CONCLUSIONS: We have found an association between low PLR and longer DFS in elderly breast cancer patients that is in line with findings in patients with a wider range of ages. Our findings on NLR contrast with those of other studies, indicating a potential differential effect in elderly patients. In addition, the effect of polypharmacy on outcome in elderly patients warrants further investigation.

Prospective analysis of psychological differences between adult and elderly cancer patients during postoperative adjuvant chemotherapy

Purpose: Despite the burgeoning geriatric population with cancer and the importance of understanding how age may be related to mental adjustment and quality of life so far, differences in coping strategies and psychological harm between the elderly and adults are hardly being taken into account to modify the approach to this population. The aim of this prospective study is to describe the differences in psychological characteristics between older and adult cancer patients and examine dissimilarities in their psychological evolution during adjuvant chemotherapy. Methods: Adults (18-69 years old) and older patients (≥ 70) with newly diagnosed non-metastatic resected cancer admitted to receive adjuvant chemotherapy were recruited. Patients completed the following questionnaires: mini-mental adjustment to cancer, brief symptom inventory, shared decision-making questionnaire-patient’s version, multidimensional scale of perceived social support, EORTC quality-of-life instrument, life orientation test-revised, and satisfaction with life scale. Results: 500 cancer patients (394 adults and 106 older) were evaluated. The impact of the diagnosis was less negative among older patients, with no differences in coping strategies, quality of life, or search for support. Regarding psychological changes from the beginning to the end of the adjuvant treatment, both age groups reported more somatic symptoms, increased psychological difficulty, reduced coping strategies, and a significant decrease in quality of life at the end of postoperative chemotherapy. Conclusion: Although there were clear psychological differences between adults and senior cancer patients, their evolution during adjuvant chemotherapy was similar, with deterioration in quality of life and coping. This negative psychological impact of adjuvant chemotherapy should be taken into account when considering interventions

The relationship between physician and cancer patient when initiating adjuvant treatment and its association with sociodemographic and clinical variables

Purpose: The aim of this study was to analyze differences in physician and patient satisfaction in shared decision-making (SDM); patients’ emotional distress, and coping in subjects with resected, non-metastatic cancer. Methods: 602 patients from 14 hospitals in Spain were surveyed. Information was collected regarding physician and patient satisfaction with SDM, participants’ emotional distress and coping, as well as patient sociodemographic and clinical characteristics by means of specific, validated questionnaires. Results: Overall, 11% of physicians and 19% of patients were dissatisfied with SDM; 22% of patients presented hopelessness or anxious preoccupation as coping strategies, and 56% presented emotional distress. By gender, female patients showed a higher prevalence of dissatisfaction with SDM (23 vs 14%), anxious preoccupation (26 vs 17%), and emotional distress (63 vs 44%) than males. Hopelessness was more prevalent in individuals with stage III disease than those with stages I-II (28 vs 18%). Conclusion: Physicians must be mindful of the importance of emotional support and individual characteristics when communicating treatment options, benefits, and adverse effects of each alternative to oncological patients

Influence of apical enlargement on the repair of apical periodontitis in rats.

AIM: To evaluate the influence of different apical enlargement protocols on the radiographic and histological healing of apical periodontitis in rats. METHODOLOGY: Apical periodontitis was induced bilaterally in the mandibular right and left first molars of 24 Wistar rats by pulp exposure to the oral cavity for 3 weeks. A standard serial root canal preparation technique was performed in the molar of one side, whilst the opposite side was the control group. Rats were randomly divided into three experimental groups (n = 8), according to the diameter of apical enlargement during root canal preparation: K-files size 20 (EG1), size 25 (EG2) and size 30 (EG3). Each animal was its own positive control, because the opposite arch remained untreated. Root canals were filled with a standard technique. After 3 weeks, the animals were euthanized. The main outcome of apical periodontitis healing was evaluated radiographically (mm2 ) and histologically (ordinal scores of inflammation) using a HE staining technique. The measurement of effect was obtained between the three experimental groups by carrying out generalized estimating equations, with Poisson regression with robust variance, pairing each experimental group with its respective control group within animals, adjusted for the mean within animal differences, with α = 5%. RESULTS: The mean and standard deviations of radiographic apical periodontitis size (mm2 ) and intensity of histological inflammatory scores were, respectively: EG1 (0.44 ± 0.27; 2.25 ± 0.46), EG2 (0.33 ± 0.10; 2.50 ± 0.53) and EG3 (0.22 ± 0.08; 2.63 ± 0.74). After 3 weeks, a significantly more favourable radiographic repair was observed when larger apical enlargement was performed (EG3), compared to EG1 and EG2 (P = 0.001). All experimental groups were associated with a significant difference on the radiographic and histological healing of apical periodontitis compared with its respective control group. CONCLUSION: Under the experimental conditions of this study, a larger apical enlargement protocol favoured a more rapid radiographic repair of apical periodontitis in rats after a 3-week follow-up.

By gender, female patients showed a higher prevalence of dissatisfaction with SDM (23 vs 14%), anxious preoccupation (26 vs 17%), and emotional distress (63 vs 44%) than males. Hopelessness was more prevalent in individuals with stage III disease than those with stages I-II (28 vs 18%). CONCLUSION: Physicians must be mindful of the importance of emotional support and individual characteristics when communicating treatment options, benefits, and adverse effects of each alternative to oncological patients.

SEOM clinical guideline for treatment of cancer pain (2017)

Pain is a highly prevalent symptom in patients with cancer. Despite therapeutic advances and well-accepted treatment guidelines, a percentage of patients with pain are under-treated. Currently, it has been recognized that several barriers in pain management still exist and, in addition, there are new challenges surrounding complex subtypes of pain, such as breakthrough and neuropathic pain, requiring further reviews and recommendations. This is an update of the guide our society previously published and represents the continued commitment of SEOM to move forward and improve supportive care of cancer patients (AU)
