Oxaliplatin-Associated Takotsubo Cardiomyopathy in a Patient with Metastatic Gastric Cancer: A Case Report.

We present the case of a 64-year-old female with stage IV gastric adenocarcinoma, pulmonary, and abdominal wall metastases, and no history of cardiovascular disease. In palliative care, she received systemic cytotoxic treatment with fluorouracil, leucovorin, oxaliplatin, and docetaxel protocol, which was well tolerated over five cycles. During cycle 6, she presented with cardiovascular symptoms with hemodynamic consequences while receiving oxaliplatin injection without docetaxel or 5-fluorouracil. She was transferred to the emergency department and then to the intensive care unit. She developed no complications during the hospital stay and was discharged after 10 days with preserved systolic function and no structural changes at the myocardial level. The electrocardiogram, echocardiogram, cardiac catheterization, and magnetic resonance imaging findings indicated an oxaliplatin-associated Takotsubo syndrome. The immunochemistry analysis showed PD-L1 expression level TPS: 40% and the foundation one genomic profiling revealed high mutation load, microsatellite instability, and HER2 not found. The patient is currently asymptomatic and on pembrolizumab monotherapy with good tolerance and partial treatment response.

Autoimmune Hemolytic Anemia Caused by Cold Agglutinin Antibodies in Systemic Lupus erythematosus-a Rare Association: Case Report.

Autoimmune hemolytic anemias (AIHAs) are rare and heterogeneous disorders characterized by the destruction of red blood cells by warm or cold antibodies. Hemolytic anemia associated with warm antibodies is the most common, whereas cold antibodies are rare and infrequent in cases published in the scientific literature. Herein, we present the case of a young patient with systemic lupus erythematosus (SLE) and autoimmune hemolytic anemia caused by cold antibodies. Initially, infectious etiology and hematological malignancy were considered, which were ruled out. She required management in the intensive care unit due to severe hematological involvement and responded well to immunomodulatory therapy. This case illustrates the importance of a strong clinical suspicion of AIHA due to cold agglutinins associated with SLE when faced with similar clinical symptoms in order to achieve a timely diagnosis and provide optimal therapy.

First case report of tumor lysis syndrome after third line systemic therapy with gemcitabine and pazopanib in a patient with lower extremity soft tissue sarcoma.

BACKGROUND: Tumor lysis syndrome (TLS) is recognized as an oncologic disorder with a variable incidence. TLS can cause the rapid destruction of tumor cells in response to oncologic therapy and is characterized by multiple electrolyte disturbances as well as its secondary complications, including death. This disease is common among patients with hematologic neoplasms, but very rare among those with solid tumors, as is the case with sarcomas. Such patients have a poor prognosis and increased risk of mortality. In the patient's particular case, this occurred after initiating third-line systemic therapy with gemcitabine associated with pazopanib, an event not previously described in the literature. CASE DESCRIPTION: We report the case of a patient with a history of high-grade sarcoma of the left lower limb T4N1M0 stage IIIB undergoing surgical management and exhibiting tumor progression with the need for third-line systemic therapy with pazopanib and gemcitabine. The patient presented with pain at the amputation site, inflammatory changes, and a tumor mass of large components on admission. They later developed electrolyte imbalance and acute renal injury compatible with TLS after systemic therapy was initiated. Pharmacological therapy, including rasburicase, was initiated based on the clinical and laboratory findings. Due to the progression of renal involvement, it was necessary to initiate haemodialysis, and during her hospital stay, the patient presented febrile syndrome associated with pancytopenia. The patient showed a favourable clinical response to the proposed antibiotic therapy and recovery of renal function, for which reason therapy was restarted with pazopanib and gemcitabine, the latter with a 20% reduction for the following cycles. Outpatient follow-up continued, completing eight cycles of treatment with good tolerance and partial clinical response; the patient died of respiratory complications eight months after discharge. CONCLUSIONS: There is limited evidence for TLS in patients with high-grade sarcoma in the literature related to the oncologic therapy used; this indicates that early risk evaluation along with prompt initiation of effective therapies is required to prevent the appearance of this type of complications in the short and long term.

Longitudinal change of inhibitory control functional connectivity associated with the development of heavy alcohol drinking.

Introduction: Heavy drinking (HD) prevalent pattern of alcohol consumption among adolescents, particularly concerning because of their critical vulnerability to the neurotoxic effects of ethanol. Adolescent neurodevelopment is characterized by critical neurobiological changes of the prefrontal, temporal and parietal regions, important for the development of executive control processes, such as inhibitory control (IC). In the present Magnetoencephalography (MEG) study, we aimed to describe the relationship between electrophysiological Functional Connectivity (FC) during an IC task and HD development, as well as its impact on functional neuromaturation. Methods: We performed a two-year longitudinal protocol with two stages. In the first stage, before the onset of HD, we recorded brain electrophysiological activity from a sample of 67 adolescents (mean age = 14.6 ± 0.7) during an IC task. Alcohol consumption was measured using the AUDIT test and a semi-structured interview. Two years later, in the second stage, 32 of the 67 participants (mean age 16.7 ± 0.7) completed a similar protocol. As for the analysis in the first stage, the source-space FC matrix was calculated, and then, using a cluster-based permutation test (CBPT) based on Spearman's correlation, we calculated the correlation between the FC of each cortical source and the number of standard alcohol units consumed two years later. For the analysis of longitudinal change, we followed a similar approach. We calculated the symmetrized percentage change (SPC) between FC at both stages and performed a CBPT analysis, analyzing the correlation between FC change and the level of alcohol consumed in a regular session. Results: The results revealed an association between higher beta-band FC in the prefrontal and temporal regions and higher consumption years later. Longitudinal results showed that greater future alcohol consumption was associated with an exacerbated reduction in the FC of the same areas. Discussion: These results underline the existence of several brain functional differences prior to alcohol misuse and their impact on functional neuromaturation.

One-year mortality after hip fracture surgery: urban-rural differences in the Colombian Andes.

To determine urban-rural differences influencing mortality in patients with hip fracture in Colombian Andes Mountains over a 1-year period. PURPOSE: To identify the urban-rural differences of sociodemographic variables, fracture-related characteristics, and preoperative and postoperative clinical factors associated with 1-year mortality in patients over 60 years old who underwent hip fracture surgery in the Andes Mountains. METHODS: A total of 126 patients with a fragility hip fracture during 2019-2020 were admitted to a tertiary care hospital. They were evaluated preoperatively and followed up until discharge. Those who survived were contacted by telephone at 1, 3, and 12 months. Univariate, bivariate, and Kaplan-Meier analyses with survival curves were performed. Relative risk was calculated with a 95% confidence interval. RESULTS: A total of 32.5% of the patients died within 1 year after surgery, with a significant difference between those who resided in rural areas (43.1%) and those who resided in urban areas (23.5%) (RR 1.70; 95% CI, 1.03 to 2.80, p = 0.036). In the multivariate analysis, anemia (hemoglobin level ≤ 9.0 g/dL during hospitalization) (RR 6.61; 95% CI, 1.49-29.37, p = 0.003), a blood transfusion requirement (RR 1.47; 95% CI, 1.07 to 2.01, p = 0.015), the type of fracture (subtrochanteric fracture (RR = 4.9, 95% CI = 1.418-16.943, p = 0.005)), and postoperative acute decompensation of chronic disease (RR 1.60; 95% CI, 1.01 to 2.53, p = 0.043) were found to be independent predictive factors of 1-year mortality after surgery. CONCLUSIONS: There was a difference in 1-year mortality between patients from rural and urban areas. More studies must be conducted to determine whether rurality behaves as an independent risk factor or is related to other variables, such as the burden of comorbidities and in-hospital complications.

Efectividad de anticoagulación regional con citrato en terapia de reemplazo renal continua / Effectiveness of regional citrate anticoagulation in continuous renal replacement therapy

BACKGROUND: Anticoagulation in continuous renal replacement therapy (CRRT) is essential to counteract the coagulation cascade activation, induced by the dialysis circuit. Heparin is the most widely used anticoagulant, followed by regional citrate anticoagulation (RCA). AIM: To determine the effectiveness and safety of anticoagulant treatment with citrate in CRRT. Material and Methods: Retrospective study of adults in CRRT hospitalized between the years 2014 and 2020 in critical units, who required change to RCA according to established protocols. RESULTS: We studied 24 patients aged 63 ± 13 years (12 females). The reasons for admission were acute kidney injury (AKI) in 80% and stage 5 chronic kidney disease in 20%. The indication of RCA in 75% of patients was by coagulation of more than 3 circuits in 24 hours. The duration of the circuit in RCA was 18.5 ± 4.8 hours versus 11.9 ± 4.9 hours with heparin (p < 0.0001). There were 19 mild complications that did not affect the RCA. Conclusions: RCA is feasible to perform, it is a safe and efficient procedure if it is protocolized, allowing a longer duration of the dialysis circuit.

ABSTRACT Objective. To evaluate the effectiveness of a standardized and simplified protocol based on the technical pillars of the HEARTS Initiative for the control of hypertensive patients in the Cardiovascular Health Program at the first level of care in Chile. Methods. Longitudinal observational study (historical cohort) in two family health centers at the first level of care in Santiago. The control of blood pressure in hypertensive adults using a standardized and simplified protocol was compared to the usual protocol based on national guidelines. Innovations in the standardized protocol included changes in how the health team is coordinated, initiation of pharmacological treatment immediately after confirmed diagnosis, standardized pharmacological treatment with a combination of at least two or three antihypertensive drugs taken daily in a single tablet. Follow-up was conducted after one year to assess the percentage of adherence to treatment and achievement of blood pressure control targets (< 140/90 mmHg). Results. A total of 1490 patients were evaluated: 562 who followed the standardized and simplified protocol, and 928 who were treated with the usual protocol (family health centers: 650; family health centers: 278). After one year, patients in the standardized and simplified protocol group had a higher proportion of adherence to blood pressure control targets (65% versus 37% and 41%, p<0.001) and higher adherence to treatment compared to those following the usual protocol (71% versus 18% and 23%, p<0.001). Conclusions. The results show that the standardized and simplified protocol is more effective than the usual protocol in controlling arterial hypertension in patients undergoing treatment at the first level of care in Chile. Its implementation at the national level could contribute to a decrease in major cardiovascular events.

Evolution of damage control surgery in non-traumatic abdominal pathology: a light in the darkness.

Damage control surgery is based on temporal control of the injury, physiologic recovery and posterior deferred definitive management. This strategy began in the 1980s and became a formal concept in 1993. It has proven to be a strategy that reduces mortality in severely injured trauma patients. Nevertheless, the concept of damage control in non-traumatic abdominal pathology remains controversial. This article aims to gather historical experiences in damage control surgery performed in non-traumatic abdominal emergency pathology patients and present a novel management algorithm. This strategy could be a surgical option to treat hemodynamically unstable patients in catastrophic scenarios such as hemorrhagic and septic shock caused by peritonitis, pancreatitis, acute mesenteric ischemia, among others. Therefore, damage control surgery is light amid better short- and long-term results.

La cirugía de control de daños es una estrategia de control temporal del daño tisular y recuperación fisiológica para un manejo definitivo diferido. Esta estrategia tiene antecedentes en el mundo del trauma desde la década de 1980, hasta su formalización conceptual en 1993. Hasta el momento ha demostrado ser una estrategia factible y que reduce la mortalidad en los pacientes críticamente enfermos. Sin embargo, el manejo de patologías abdominales no traumáticas aun es tema de discusión sobre su factibilidad y seguridad. El presente articulo tiene como objetivo realizar un relato histórico y experiencias en la aplicación de la cirugía de control de daños en emergencias quirúrgicas abdominales no asociadas a trauma y presentar un algoritmo de manejo usando los principios de la cirugía de control de daños. La aplicabilidad del control de daños en no trauma se enfrenta a los contextos de shock hemorrágico y séptico para patologías como peritonitis generalizada, peritonitis postquirúrgica, pancreatitis, isquemia mesentérica aguda, entre otras. Se ha demostrado que el uso de control de daños representa una luz para el cirujano ante la tormenta de la incertidumbre de la descompensación metabólica en el manejo de emergencias abdominales, para crear un puente para su manejo definitivo y permitir anastomosis como estrategia de reconstrucción intestinal y mejorar los resultados a corto y largo plazo.

Aneurisma aórtico abdominal asociado a coagulación intravascular diseminada crónica: una complicación rara / Abdominal aortic aneurysm associated with chronic disseminated intravascular coagulation: a rare complication

Resumen La coagulación intravascular diseminada es un proceso sistémico caracterizado por la activación generalizada de la coagulación, que tiene el potencial de causar trombosis vascular, hemorragia y falla orgánica. En raras ocasiones, las anomalías vasculares, como el aneurisma aórtico abdominal, pueden desencadenar coagulación intravascular diseminada crónica. Los aneurismas aórticos grandes, su disección y su expansión son factores de riesgo. En estos casos predominan los síntomas subclínicos y la coagulopatía solo se identifica mediante pruebas de laboratorio. Existe evidencia limitada basada en la experiencia de series de casos de coagulación intravascular diseminada crónica como complicación en pacientes con aneurisma aórtico abdominal. Además, la duración y la respuesta terapéutica a la heparina no se conocen bien, principalmente en los pacientes con manejo conservador. Se considera un desafío diagnóstico y terapéutico debido a la baja frecuencia de presentación. A continuación, se describen las características clínicas y paraclínicas, así como el tratamiento, de un paciente con aneurisma aórtico abdominal asociado con coagulación intravascular diseminada crónica.

Abstract Disseminated intravascular coagulation is a systemic process characterized by the widespread activation of coagulation with the potential for causing vascular thrombosis, hemorrhage and organ failure. Rarely, vascular anomalies like abdominal aortic aneurysm can trigger chronic disseminated intravascular coagulation. Large aortic aneurysms, dissection and expansion are risk factors. In these cases, subclinical symptoms predominate and coagulopathy is only identified by laboratory tests. Nowadays there is limited evidence based on experience from case series of chronic disseminated intravascular coagulation as complication in patients with abdominal aortic aneurysm. Furthermore, duration and therapeutic response with heparin therapy are not well known, mainly in those patients with conservative management. It is considered a diagnostic and therapeutic challenge due to the low presentation frequency. The clinical characteristics, laboratory and treatment of a patient with abdominal aortic aneurysm associated with chronic disseminated intravascular coagulation are described below.

Damage control in penetrating duodenal trauma: less is better - the sequel.

The overall incidence of duodenal injuries in severely injured trauma patients is between 0.2 to 0.6% and the overall prevalence in those suffering from abdominal trauma is 3 to 5%. Approximately 80% of these cases are secondary to penetrating trauma, commonly associated with vascular and adjacent organ injuries. Therefore, defining the best surgical treatment algorithm remains controversial. Mild to moderate duodenal trauma is currently managed via primary repair and simple surgical techniques. However, severe injuries have required complex surgical techniques without significant favorable outcomes and a consequential increase in mortality rates. This article aims to delineate the experience in the surgical management of penetrating duodenal injuries via the creation of a practical and effective algorithm that includes basic principles of damage control surgery that sticks to the philosophy of "Less is Better". Surgical management of all penetrating duodenal trauma should always default when possible to primary repair. When confronted with a complex duodenal injury, hemodynamic instability, and/or significant associated injuries, the default should be damage control surgery. Definitive reconstructive surgery should be postponed until the patient has been adequately resuscitated and the diamond of death has been corrected.

El trauma de duodeno comúnmente se produce por un trauma penetrante que puede asociarse a lesiones vasculares y de órganos adyacentes. En el manejo quirúrgico se recomienda realizar un reparo primario o el empleo de técnicas quirúrgicas simples. Sin embargo, el abordaje de lesiones severas del duodeno es un tema controversial. Anteriormente, se han descrito técnicas como la exclusión pilórica o la pancreatoduodenectomía con resultados no concluyentes. El presente artículo presenta una propuesta del manejo de control de daños del trauma penetrante de duodeno, a través, de un algoritmo de cinco pasos. Este algoritmo plantea una solución para el cirujano cuando no es posible realizar el reparo primario. El control de daños del duodeno y su reconstrucción depende de una toma de decisiones respecto a la porción del duodeno lesionada y el compromiso sobre el complejo pancreatoduodenal. Se recomiendan medidas rápidas para contener el daño y se proponen vías de reconstrucción duodenal diferente a las clásicamente descritas. Igualmente, la probabilidad de complicaciones como fistula duodenales es considerable, por lo que proponemos, que el manejo de este tipo de fistulas de alto gasto se aborde por medio de una laparostomía retroperitoneal (lumbotomía). El abordaje del trauma penetrante de duodeno se puede realizar a través del principio "menos es mejor".

Damage control surgical management of combined small and large bowel injuries in penetrating trauma: Are ostomies still pertinent?

Hollow viscus injuries represent a significant portion of overall lesions sustained during penetrating trauma. Currently, isolated small or large bowel injuries are commonly managed via primary anastomosis in patients undergoing definitive laparotomy or deferred anastomosis in patients requiring damage control surgery. The traditional surgical dogma of ostomy has proven to be unnecessary and, in many instances, actually increases morbidity. The aim of this article is to delineate the experience obtained in the management of combined hollow viscus injuries of patients suffering from penetrating trauma. We sought out to determine if primary and/or deferred bowel injury repair via anastomosis is the preferred surgical course in patients suffering from combined small and large bowel penetrating injuries. Our experience shows that more than 90% of all combined penetrating bowel injuries can be managed via primary or deferred anastomosis, even in the most severe cases requiring the application of damage control principles. Applying this strategy, the overall need for an ostomy (primary or deferred) could be reduced to less than 10%.

El trauma de las vísceras huecas representa una gran proporción de las lesiones asociadas al trauma penetrante. Actualmente, las lesiones aisladas de intestino delgado o colon se manejan a través de anastomosis primaria en pacientes sometidos a laparotomía definitiva o anastomosis diferida en pacientes que requieran cirugía de control de daños. El dogma quirúrgico tradicional de la ostomía se ha probado que es innecesario y en muchos casos puede aumentar la morbilidad. El objetivo de este artículo es describir la experiencia obtenida en el manejo de lesiones combinadas de vísceras huecas de pacientes con trauma penetrante. Se determinó que el manejo primario o diferido del intestino a través de anastomosis es el abordaje quirúrgico preferido en pacientes que presentan lesiones penetrantes combinadas de intestino delgado y colon. Se ha reportado que el 90% de lesiones combinadas penetrantes intestinales pueden ser manejadas a través de anastomosis primaria o diferida incluso en los casos más severos requieren la aplicación de los principios de control de daños. Aplicando esta estrategia, la tasa general para ostomía (primaria o diferida) puede ser reducida a menos del 10%.

Rabdomiólisis como presentación inicial de COVID-19: caso Clínico / Rhabdomyolysis as the presentation form of COVID-19 infection: report of one case

COVID-19 infection causes a systemic inflammatory response, which mainly presents as a febrile syndrome with respiratory involvement. We report a 37-year-old male who consulted for myalgia, nausea and epigastric pain lasting three days. On admission, he had crepitations at the lung bases. The initial laboratory showed a creatine kinase of 62,768 U/L, a LDH of 1,110 IU/L, a creatinine a 2.1 mg/dL, an aspartate aminotransferase of 1,347 IU/L, a D-dimer of 1,140 ng/mL, a ferritin of 1,201 ng/mL and a lymphocyte count of 810 cells/mm3. The chest CT scan was compatible with multifocal pneumonia, suggesting a COVID-19 infection. COVID-19 PCR was positive. The patient was managed with hydration, sodium bicarbonate, ceftriaxone, and azithromycin, with a good clinical response.

Effectiveness of triple therapy with dapagliflozin add-on to dual therapy over 52 weeks in patients with uncontrolled type 2 diabetes mellitus in a centre of high complexity, Cali-Colombia

ABSTRACT Objectives: To evaluate the effectiveness of adding dapagliflozin as an intensification strategy for the treatment of patients with uncontrolled type 2 diabetes mellitus (T2DM). Materials and methods: A historical cohort study was conducted in 123 adult patients over 18 years old who were diagnosed with uncontrolled T2DM, who received dapagliflozin add-on to their dual base treatment: metformin plus glibenclamide (n = 32), metformin plus saxagliptin (n = 29), metformin plus exenatide (n = 28), or metformin plus insulin (n = 34). The endpoints were evaluated using analysis of variance. Results: All the patients completed a 52-week follow-up. Overall, 52.85% of patients were female, the Hispanic population represented the largest proportion of patients in all groups (60.98%), and the mean ± SD patient age and body weight were 55.05 ± 7.58 years and 83.55 ± 9.65 kg, respectively. The mean ± SD duration of T2DM, glycated hemoglobin (HbA1c), and fasting plasma glucose (FPG) were 5.93 ± 2.98 years, 8.1 ± 0.53%, and 166.03 ± 26.80 mg/dL, respectively. The grand mean changes of HbA1c, FPG, body weight and blood pressure showed a decreasing trend during the study period and it was statistically significant in all groups (p-value = <0.001). The proportion of patients achieving HbA1c target (<7%) was highest in the group that used a dapagliflozin add-on to metformin plus saxagliptin. Conclusion: The addition of dapagliflozin as an alternative for intensification of dual therapy consistently improved, not only FPG and HbA1c, but also body weight and blood pressure, with statistically significant results.

Damage Control Surgery may be a Safe Option for Severe Non-Trauma Peritonitis Management: Proposal of a New Decision-Making Algorithm.

BACKGROUND: Damage control surgery (DCS) has emerged as a new option in the management of non-traumatic peritonitis patients to increase survival in critically ill patients. The purpose of this study was to compare DCS with conventional strategy (anastomosis/ostomies in the index laparotomy) for severe non-traumatic peritonitis regarding postoperative complications, ostomy rate, and mortality and to propose a useful algorithm in the clinical practice. METHODS: Patients who underwent an urgent laparotomy for non-trauma peritonitis at a single level I trauma center in Colombia between January 2003 and December 2018, were retrospectively included. We compared patients who had DCS management versus definitive initial surgical management (DISM) group. We evaluated clinical outcomes and morbidities among groups. RESULTS: 290 patients were included; 81 patients were treated with DCS and 209 patients underwent DISM. Patients treated with DCS had a worse critical status before surgery with higher SOFA score [median, DCS group: 5 (IQR: 3-8) vs. DISM group: 3 (IQR: 1-6), p < 0.001]. The length of hospital stay and overall mortality rate of DCS group were not significant statistical differences with DISM group. Complications rate related to primary anastomosis or primary ostomy was similar. There is not difference in ostomy rate among groups. At multivariate analysis, SOFA > 6 points and APACHE-II > 20 points correlated with a higher probability of DCS. CONCLUSION: DCS in severe non-trauma peritonitis patients is feasible and safe as surgical strategy management without increasing mortality, length hospital of stay, or complications. DCS principles might be applied in the non-trauma scenarios without increase the stoma rate.

[Hypophosphatemia induced by carboxymaltose iron and imatinib. Report of two cases]. / Hipofosfatemia inducida por drogas: fierro carboximaltosa e imatinib. Casos clínicos.

Hypophosphatemia is a relatively frequent and a potentially serious adverse drug effect. Clinically it is characterized by bone pain and muscle weakness. There are several mechanisms by which a drug can induce hypophosphatemia and they can be classified according to whether or not they are mediated by an excess of Fibroblast Growth Factor 23 (FGF23). We report two patients with the condition: (i) A 49-year-old woman with Chronic Myeloid Leukemia (CML) and gastric sleeve surgery at 46 years of age. After receiving intravenous carboxymaltose iron in one occasion due to refractory anemia, she developed symptomatic hypophosphatemia. Urinary phosphate losses associated with high FGF23 levels were confirmed. Plasma phosphate returned to normal values 90 days after the iron administration. (ii) A 40-year-old man with a history of CML in whom imatinib was started. He developed symptomatic hypophosphatemia due to non FGF23-mediated hyperphosphaturia. As treatment with imatinib could not be interrupted, hypophosphatemia and its symptoms resolved with oral phosphate intake. These cases illustrate the importance of recognizing and treating drug-induced hypophosphatemia in a timely manner, and thus avoid the morbidity associated with this entity.
