  • Decision making among older adults in hemodialysis. A qualitative
           assessment

    • Abstract: Background: In Chile there are 22,310 people in Chronic Hemodialysis (CHD), 53% of them older adults (OA). Shared decision-making and advance directives (AD) are especially important in OA with end-stage chronic renal failure, since they have greater levels of disability, morbidity and mortality, raising doubts about the benefit of therapy. Aims: To understand the experience in decision making and explore ways to express AD, in OA in CHD. Material and Methods: A qualitative phenomenological study, performing 12 in-depth interviews to OA who had been at CHD for at least one year. Results: The analysis revealed four broad comprehensive categories, two related to participation in the decision to enter CHD, namely the experience of subjects as spectators and their lack of interest for decision support and two referred to the expression of AD, namely the difficulty in facing their own finitude and resistance to express AD. Conclusions: There is little participation of older adults in the decision about their admission to dialysis therapy, and once they enter the CHD program they are not prepared to discuss AD in general, nor an eventual suspension of dialysis in particular.
       
  • Variceal and non-variceal upper gastrointestinal bleeding. Analysis of 249
           hospitalized patients

    • Abstract: Background: Upper gastrointestinal bleeding (UGIB) is one of the main reasons of hospitalization due to gastrointestinal causes. Reported mortality rates range from 5 to 12%. Aim: To determine hospital mortality and associated risk factors in hospitalized patients with UGIB. To compare the clinical characteristics and outcomes of patients with variceal versus non-variceal UGIB. Material and Methods: Review of medical records of 249 patients (62% males) discharged with the diagnosis of UGIB at a clinical hospital between 2015 to 2017. Demographic and clinical characteristics and adverse clinical outcomes (surgery, length of hospital stay and in-hospital mortality) were recorded. A comparative analysis between patients with Variceal and Non-variceal UGIB was carried out. Results: Seventy two percent of UGIB were non-variceal (peptic ulcer in 44%). Two patients required surgery (both died). Median of length of hospital stay was seven days (interquartile range (IQR) 4-13). Overall hospital mortality was 13 and 4% in variceal and non-variceal UGIB, respectively (p = 0.024). The variables associated with mortality were: red blood cell transfusion (odds ratio (OR): 18.7, p < 0.01), elevated creatinine on admission (OR: 3.30, p = 0.03) and variceal bleeding (OR: 3.23, p = 0.02). Conclusions: Hospital mortality of UGIB remains high, especially in variceal UGIB. Elevated creatinine levels on admission, the need of transfusion of red blood cells and variceal etiology are risk factors for mortality.
       
  • Association of physical inactivity with low levels of education

    • Abstract: Background: A higher educational level is associated with healthier lifestyles. Aim: To assess the association between the level of compliance with physical activity recommendations and years of formal education in Chilean adults. Material and Methods: Analysis include 6,174 participants from the National Health Survey 2016-2017. Physical activity levels were assessed through the Global Physical Questionnaire (GPAQ v2). Physical inactivity was defined as < 600 MET/minute/week. Results: Among subjects without education, 44% and 27% of women and men respectively, were physically inactive. Among women and men with the highest number of years of education (> 16) the figures for physical inactivity were 27% and 15% respectively. The odds for not meeting the physical activity recommendations was 2.3 [95% confidence intervals (CI): 1.57; 3.38] and 3.9 [95% CI: 2.27; 6.95] in women and men without any formal education respectively, as compared with those who reported 12 years of education. Women and men who reported a high level of education ≥ (16 years) did not show significant differences compared to the reference group. Conclusions: People with low levels of education are were likely to be physically inactive.
       
  • User perceptions of a public health program to reduce disability among
           Chilean older adults

    • Abstract: Background: The Program “Más Adultos Mayores Autovalentes” (Más AMA) started in 2015 as a strategy for the prevention of disability among older adults. Aim: To describe the health benefits, from user's perspective, of the Functional Stimulation Component of the Más AMA program. Material and Methods: Eleven focus groups including 97 participants of the Más AMA program were conducted in Northern Metropolitan Santiago municipalities. Results: The benefits perceived by Más AMA participants were a reduction in loneliness and isolation, physical reactivation, engagement in activities, and the use of support resources within the community. The relationship with professionals working at Más AMA was described as highly satisfactory. Conclusions: The benefits of attending the Más AMA program from the point of view of their users are mainly related with social and affective dimensions, which contrast with the emphasis in physical and cognitive dimensions given by the technical orientation of the Más AMA program.
       
  • Assessment of two frailty scales for the preoperative period

    • Abstract: Background: In the perioperative context, a frailty evaluation scale must consider certain characteristics such as validation, execution speed, simplicity, the capacity to measure multiple dimensions and not being dependent on a cognitive or physical test that could not be performed prior to surgery. The test should select patients that could benefit from interventions aimed to improve their postoperative outcomes. Aim: To validate two frailty evaluation scales for the perioperative period. Material and Methods: The Risk Analysis Index with local modifications (RAI-M) were applied to 201 patients aged 73 ± 7 years (49% women) and the Edmonton frailty scale were applied in 151 patients aged 73 ± 7 years (49% women) in the preoperative period. Their results were compared with the Rockwood frailty index. Results: The Edmonton frail scale showed adequate psychometric properties and assessed multiple dimensions through 8 of the 11 original questions, achieving a discrimination power over 80% compared to the Rockwood Index. The RAI- M, demonstrated solid psychometric properties with a tool that examines 4 dimensions of frailty through 15 questions and reviewing the presence of 11 medical comorbidities. This scale had a discrimination power greater than 85% and it was significantly associated with prolongation of the planned hospital stay and mortality. Conclusions: RAI-M is a short and easily administered scale, useful to detect frailty in the preoperative period.
       
  • Lymphadenopathies in patients with rheumatic diseases. Review of 19 cases

    • Abstract: Background: The presence of multiple lymphadenopathies can be a diagnostic challenge. Aim: To describe the clinical, laboratory and imaging characteristics of 19 patients with lymphadenopathies of rheumatologic origin. Material and Methods: Review of medical records of 19 patients aged 16 to 72 years (68%) with lymphadenopathies presumably secondary to a rheumatic disease. Results: Six patients had systemic lupus erythematosus, six had Sjogren's disease, three had sarcoidosis, two had rheumatoid arthritis, one had IgG4 related disease and one had mixed connective tissue disease. A lymph node biopsy was performed in 11 patients and in eight a lymphoid follicular hyperplasia was found. Systemic symptoms were reported by 68% of patients. Blood lactate dehydrogenase was elevated only in cases associated with hemolytic anemia. There was no specific or predictable localization of the lymphadenopathies in imaging studies, except in the cases of sarcoidosis. The average size of the lymphadenopathies was 13.5 mm in diameter in short axis and there was no presence of necrosis, calcification, or conglomerate formation. Only one case presented splenomegaly. All patients responded favorably to corticosteroids. Conclusions: Lymphadenopathies associated with rheumatologic diseases can occur in a wide variety of diseases, especially systemic lupus erythematosus and Sjögren's disease. The absence of LDH elevation and splenomegaly and the absence of imaging findings such as conglomerates can orient to a rheumatologic origin.
       
  • Primary cardiac tumors. Experience in 72 cases

    • Abstract: Background: Primary cardiac tumors have a low incidence, and their presentation form and clinical course are not well known. Aim: To describe the characteristics, treatment, follow up and survival of patients with primary cardiac tumors (PCT). Material and Methods: Review of all surgical procedures for PCT performed between 1984 and 2019 in a regional general hospital. The information was obtained from surgical protocols, surgical and pathology databases, medical records and registries of the Chilean National Identification Service. The clinical features of patients, immediate and long term outcomes are described. Results: Seventy-two surgical procedures for PCT were reviewed. Patients’ age was 55 ± 15 years and 60% were women. The most common histological types were myxoma in 49 patients (68%), papillary fibroelastoma in 13 (18%) and sarcoma in 6 (8.3%). Forty-nine (68.1%) were symptomatic and all tumors were found on echocardiography. Fifty-one (71%) were in the left atrium, 10 (14%) in the aortic valve and eight (11%) in the right atrium. The surgical procedures were tumor resection in 48 patients (67%) and resection and repair with patch in 23 (32%). Mean postoperative stay was 6.6 ± 4.4 days, eight patients (11%) had complications and no patient died in the immediate postoperative period. Long term survival was higher in patients with benign PCT as compared with those with malignant tumors. Conclusions: Most PCTs in this group of patients were benign neoplasms and the most common tumors were myxomas. The main diagnostic method is echocardiography and the prognosis of surgical treatment is excellent when the tumors are benign. (Rev Med Chile 2020; 148: 327-335)
       
  • Validation of the Childhood Trauma Questionnaire-Short Form in Chile

    • Abstract: Background: Childhood Trauma Questionnaire-Short Form (CTQ-SF) is an instrument to assess child abuse and neglect Aim: to adapt and confirm the psychometric properties of the Spanish version of the CTQ-SF in Chile. Material and Methods: The CTQ-SF was applied to 89 clinically depressed subjects (77.5% women) who consulted at an outpatient mental health clinic. Confirmatory factor analysis (CFA), reliability (Cronbach’s α) tests, and convergent validity analyses with clinical markers of complex depression were carried out. Results: The Chilean version of the CTQ-SF demonstrated an acceptable fit to a five-factor model, with adequate psychometric properties. The CFA revealed that a better fit to a five-factor model would be achieved after elimination of two items from the physical neglect scale, the less reliable scale of the questionnaire. The physical abuse scale discriminated between patients with a complex depression versus non-complex depression, and all the CTQ-SF’s scales discriminated between patients with high suicide risk and/or history of psychiatric admissions versus those patients without this background. Conclusions: the Chilean version of the CTQ-SF shows evidence of structural and discriminant validity, and reliability, in a clinical sample. Better alternatives to specifically assess the physical neglect construct should be developed.
       
  • Penicillin desensitization in allergic pregnant women with syphilis.
           Report of two cases

    • Abstract: ABSTRACT Syphilis during pregnancy has a high risk of congenital transmission with disastrous fetal consequences. Penicillin (PNC) is the only effective antimicrobial for the treatment of pregnant women with syphilis. Chilean guidelines do not consider desensitization to PNC in these women. We report two cases of pregnant women aged 32 and 23 years, with immediate allergy to PNC and syphilis who were safely and successfully desensitized using a four-hour intravenous protocol in the critical care unit and who subsequently received benzathine G PNC. An electronic survey was conducted among approximately 100 Clinical Pharmacists (CP) in the country. Of these, 16 answered and 13 reported having experience in drug desensitization, in at least five cases with PNC and none reported deaths or cardiorespiratory arrest. Desensitization to PNC can be carried out safely and in Chile, this alternative should be incorporated to the management of pregnant women with syphilis and immediate allergy to PNC, instead of using erythromycin.La sífilis durante el embarazo tiene un alto riesgo de transmisión congénita con consecuencias desastrosas para el feto. La penicilina (PNC) es el único compuesto efectivo para el tratamiento de sífilis en una mujer embarazada.. En Chile, ante alergias de tipo inmediata, no se considera la desensibilización a la PNC en mujeres embarazadas por norma ministerial. Se comunican dos casos de mujeres embarazadas con alergia tipo inmediata y sífilis durante la gestación que fueron desensibilizadas a este compuesto con un protocolo endovenoso de 4 horas en la unidad de pacientes críticos, sin observar complicaciones, recibiendo posteriormente PNC G Benzatina. Se efectuó una encuesta electrónica a farmacéuticos clínicos del país que incluyó más de 100 profesionales. De ellos, 16 contestaron y 13 declararon poseer experiencia en desensibilización de fármacos, en al menos cinco casos con PNC y ninguno reportó muertes o paro cardiorrespiratorio. La desensibilización a PNC puede ser efectuada en forma segura en embarazadas con alergia de tipo inmediata a PNC que cursan con sífilis. En Chile se debería incorporar esta alternativa en el manejo de mujeres embarazadas con sífilis y alergia inmediata a PNC en lugar de solo considerar por norma el uso de eritromicina.
       
  • With regard to COVID-19 contingency. ECMO in adults. Extracorporeal
           Membrane Oxygenation). To whom, how and when

    • Abstract: ECMO (Extracorporeal Membrane Oxygenation) is an extracorporeal life support system in catastrophic lung failure, shock and cardiopulmonary resuscitation, in different age groups, with multiple physiologic features. When the candidate to be submitted is too unstable to be transported to a hospital with ECMO, cannulation before transfer allows stabilization and subsequent transport. The aim of this article is to review the current concepts of extracorporeal support, its indications, national and international experience, and its possible role in the SARS-Cov2 pandemic.
       
  • Biomarkers in inflammatory bowel disease

    • Abstract: Biomarkers in inflammatory bowel disease are an essential tool in clinical practice. They allow a non-invasive evaluation of patients and thus guide decision-making at different stages of the disease, including diagnostic suspicion, severity assessment, relapse prediction, and treatment response. Although biomarkers in blood such as erythrocyte sedimentation rate and C-reactive protein, are the most commonly used biomarkers, because their low cost and accessibility, they lack specificity. Currently, fecal biomarkers offer greater reliability, applicability, and specificity. Fecal calprotectin is the most commonly used marker. This review discusses the advantages and disadvantages of biomarkers in inflammatory bowel disease, as well as their clinical applications and new biomarkers currently under research.
       
  • Hemophagocytic syndrome, current diagnostic and therapeutic approach

    • Abstract: Hemophagocytic syndrome or hemophagocytic lymphohistiocytosis (HLH) is a highly lethal hyper-inflammatory disorder that leads to a storm of cytokines, hemophagocytosis and multiple organ failure. It can be primary, which is inherited, or secondary. In the latter, virus infections are a frequent trigger, predominantly the family of herpes viruses, such as Epstein-Barr virus. An early treatment is recommended. Until recently there was no consensus about the management of secondary cases. The protocols for the treatment of primary HLH were used, which include cytotoxic agents and corticosteroids. We herein review the current diagnostic and therapeutic approach of HLH, based on a case associated with a reactivation of the Epstein-Barr virus in an immunocompetent adolescent. We highlight the importance of suspecting this disease in patients with a persistent inflammatory response state or with a fever of unknown origin, in order to carry out a timely treatment, with the least toxicity, and appropriate to the characteristics of each individual, which is the current therapeutic trend.
       
  • A proposal of the Chilean Academy of Medicine to improve organ procurement
           and transplantation in Chile

    • Abstract: The Chilean Academy of Medicine designated a group of specialists to evaluate the practice and to propose reforms for organ donation and transplantation, due to the general insufficiencies at the national level with these procedures. In the last six years the mean number of organ transplants in Chile was 340 cases per year while effective cadaveric donors ranged between 6 and 10 per million inhabitants. These averages remained stable during this period and are among the lowest in the region. Our analysis attributed these deficient results mainly to low organ donation and inefficient procurement due to lack of compliance with protocols and little accountability. The committee proposes several measures for improvement. These are a systematic and obligatory report of potential organ donors by all emergency and critical care centers, frequent evaluation of results, empowering of health authorities to correct insufficiencies in organ procurement, education programs for primary, secondary, technical and university students to improve their knowledge about the social significance and solidarity required for transplantation policies and specialized updated training of all health professionals involved. Organ donation and transplantation must be based on clear and fair ethical considerations in order to be accepted by the general public.
       
  • Ernestina Pérez Barahona (1865-1951). Her medical attempt to rescue
           the chilean race

    • Abstract: This article analyzes some publications of Ernestina Pérez Barahona (1865-1951), the second Chilean and Latin American female physician. It exposes her concern for the public health and, more precisely, for the problem of the Chilean race. She constantly refers to hygiene in her conferences, articles and books published between 1887 and 1920. Thus, the aim of this review is to recover her production and to inform the readers about her intervention as a medical professional.
       
  • Ethical guidelines for medical decision-making during COVID-19 pandemic in
           Chile

    • Abstract: The catastrophic emergency experienced by many countries with the COVID-19 pandemic emphasized the importance of bioethics for decision-making, both at the public health (equitable and effective policies) and at the clinical level. At the clinical level, the issues are the fulfillment of medical care demand with adequate health care teams, infrastructure, and supplies, and to cover critical care demands that surpass the available resources. Therefore, ethically correct approaches are required for the allocation of life sustaining resources. There are recommendations for the allocating life support during disasters based on multiple considerations, including ethical ones. However, the ethical criteria of existing guidelines are variable. Ethical principles usually considered are saving the greatest number of lives, saving the greatest number of years of life and the principle of the life cycle or the goal to give each individual equal opportunity to live through the various phases of life. However, the centrality of the human being and the search for the common good should be considered. Knowledge of public perspectives and moral benchmarks on these issues is essential. A successful assignment effort will require everyone's trust and cooperation. Decision making should be planned and discussed in advance, since in-depth deliberation will be extremely complex during the disaster. Our goal is to help the health care teams to wisely allocate resources in shortage periods.
       
  • Ethics code of the medical college of Chile. Critical analysis of a
           modification

    • Abstract: The code of ethics of the Medical College of Chile was modified in December 2019. The amendment was mainly to article 8, which refers to the doctor’s duty to care for the pregnant woman and the child she is carrying. The change maintains this duty, but allows doctors to perform abortions, introducing three considerations that act as new principles or values for the medical profession: the plurality of values existing in society, the autonomy of women and what is established by law. This paper is a reflection on codes of ethics, their relationship with values, and with legislation. Also it shows the consequences that this modification represents for the principles governing medical activity, the status of medical specialties, the commitment of doctors to their patients and the validity of the code of ethics.
       
  • Hypophosphatemia induced by carboxymaltose iron and imatinib. Report of
           two cases

    • Abstract: 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.
       
  • Combined use of left ventricular assist devices in cardiogenic shock.
           Report of one case

    • Abstract: We report a 55-year-old woman with a history of hypothyroidism and type 2 diabetes mellitus who consulted at the emergency room because of intermittent oppressive chest discomfort. At admission, electrocardiogram showed a complete atrioventricular block. A transthoracic echocardiogram disclosed severe left ventricular dysfunction. The patient developed cardiogenic shock that required the installation of the Impella system. An emergency coronary angiography showed an ostial occlusion of the anterior descending artery. Despite successful primary angioplasty, she persisted with refractory shock and progressive hypoxemia. A concomitant connection to the extracorporeal membrane oxygenation system (ECMO) was decided. The support of both devices allowed the stabilization of the patient and the improvement of perfusion parameters.
