Prótesis colónicas en el tratamiento paliativo del cáncer colónico. Nuestra evaluación tras 10 años de experiencia / Self-expanding metal stents in the palliative treatmentof coloncancer. Results of 10 years of experience

Introducción: la colocación de prótesis metálicas autoexpansibles (PAE) por vía endoscópica surge como opción terapéutica para la obstrucción colónica neoplásica en dos situaciones: como tratamiento paliativo y como puente a la cirugía curativa. Este procedimiento evita cirugías en dos tiempos y disminuye la probabilidad de colostomía definitiva y sus complicaciones con el consecuente deterioro de la calidad de vida. Objetivo: comunicar nuestra experiencia en la colocación de PAE para el tratamiento paliativo de la obstrucción colorrectal neoplásica. Diseño: retrospectivo, longitudinal, descriptivo y observacional. Material y métodos: se incluyeron todos los pacientes a quienes el mismo grupo de endoscopistas les colocó PAE con intención paliativa por cáncer colorrectal avanzado entre agosto de 2008 y diciembre de 2019. Fueron analizadas las variables demográficas y clínicas, el éxito técnico y clínico, las complicaciones tempranas y tardías y la supervivencia. Resultados: se colocó PAE en 54 pacientes. La media de edad fue 71 años. El 85% de las lesiones se localizó en el colon izquierdo. En el 57% de los pacientes se realizó en forma ambulatoria. El éxito técnico y clínico fue del 92 y 90%, respectivamente y la supervivencia media de 209 días. La tasa de complicaciones fue del 29,6%, incluyendo un 14,8% de obstrucción y un 5,6% de migración. La mortalidad tardía atribuible al procedimiento fue del 5,6%, ocasionada por 3 perforaciones tardías: 2 abiertas y 1 microperforación con formación de absceso localizado. Conclusiones: la colocación de PAE como tratamiento paliativo de la obstrucción neoplásica colónica es factible, eficaz y segura. Permitió el manejo ambulatorio o con internación breve y la realimentación temprana, mejorando las condiciones para afrontar un eventual tratamiento quimioterápico paliativo. Las mayoría de las complicaciones fueron tardías y resueltas endoscópicamente en forma ambulatoria. (AU)

Introduction: endoscopic placement of self-expanding metal stents (SEMS) emerges as a therapeutic option for neoplastic obstruction of the colon in two situations: as palliative treatment and as a bridge to curative surgery. This procedure avoids two-stage surgeries and reduces the probability of permanent colostomy and its complications with the consequent deterioration in quality of life. Objective: to report our experience in the placement of SEMS as palliative treatment in neoplastic colorectal obstruction. Design: retrospective, longitudinal, descriptive and observational study. Methods: all patients in whom the same group of endoscopists performed SEMS placement with palliative intent for advanced colorectal cancer between August 2008 and December 2019 were analyzed. Data collected were demographic and clinical variables, technical and clinical success, early and late complications, and survival. Results: SEMS were placed in 54 patients. The average age was 71 years. Eighty-five percent were left-sided tumors. In 57% of the patients the procedure was performed on an outpatient basis. Technical and clinical success was 92 and 90%, respectively, and median survival was 209 days. The complication rate was 29.6%, including 14.8% obstruction and 5.6% migration. Late mortality attributable to the procedure was 5.6%, caused by 3 late perforations: 2 open and 1 microperforation with localized abscess formation. Conclusions: The placement of SEMS as a palliative treatment for neoplastic colonic obstruction is feasible, effective and safe. It allowed outpa-tient management or brief hospitalization and early refeeding, improving the conditions to face an eventual palliative chemotherapy treatment. Most complications were late and resolved endoscopically on an outpatient basis. (AU)

Complicaciones perianales causadas por agentes modeladores inyectados en glúteos / Perianal complications caused by gluteal injection of modeling agents

En este reporte presentamos tres pacientes en quienes ocurrieron condiciones inflamatorias perianales tardías, luego de la administración de sustancias modeladoras no identificadas en los glúteos. El diagnóstico inicial y supuesto no fue correcto, ya que no se investigó durante la evaluación preliminar el antecedente de la administración de elementos modeladores. Recomendamos que los pacientes con patologías inflamatorias del ano, sobre todo aquellos cuyo curso es extraño, se les pregunte acerca de la administración de agentes modeladores en los glúteos. Esta práctica puede contribuir a la eficacia del diagnóstico de manifestaciones perianales caracterizadas por flogosis, que se presentan de forma inusual. (AU)

In this report we present three patients in which late perianal inflammatory conditions occurred after administration of unidentified modeling agents to the buttocks. The initial diagnosis was not correct because of the administration of modeling agents was not investigated during the initial eval-uation. We recommend inquiring patients with inflammatory pathologies of the anus, especially those whose course is unusual, about the adminis-tration of modeling agents to the buttocks. This approach can contribute to the efficiency of the diagnosis of perianal complaints characterized by inflammation, but rare in its appearance. (AU)

Estudio de la vía aérea superior frente a apneas obstructivas del sueño persistentes en pediatría / An approach to the upper airway evaluation in pediatric persistent obstructive sleep apnea

El síndrome de apneas obstructivas del sueño (SAOS) en pediatría constituye un trastorno asociado a múltiples consecuencias en el espectro cognitivo y comportamental. El principal factor de riesgo asociado es la hipertrofia amigdalina y las vegetaciones adenoideas. La adenoamigdalectomía es el tratamiento de primera línea. La incidencia del SAOS persistente varía entre un 15 % y un 75 % según las comorbilidades. Este se presenta como un desafío a la hora de tratarlo; requiere un abordaje integral para su diagnóstico y tratamiento adecuado. El objetivo de esta revisión bibliográfica es proponer un abordaje diagnóstico y terapéutico para el SAOS persistente.

In pediatrics, obstructive sleep apnea syndrome (OSAS) is a disorder associated with multiple consequences at the cognitive and behavioral level. The main associated risk factor is the presence of tonsillar hypertrophy and adenoids. An adenotonsillectomy is the first-line treatment. The incidence of persistent OSAS varies from 15% to 75%, depending on comorbidities. This is a challenge in terms of management; it requires a comprehensive approach for an adequate diagnosis and treatment. The objective of this bibliographic review is to propose a diagnostic and therapeutic approach for persistent OSAS.

Trasplante de médula ósea haploidéntico en un paciente pediátrico con síndrome de Wiskott-Aldrich. A propósito de un caso / Haploidentical bone marrow transplantation in a pediatric patient with Wiskott-Aldrich syndrome. A case report

El síndrome de Wiskott-Aldrich es un error innato de la inmunidad de herencia ligada al cromosoma X, producido por variantes en el gen que codifica la proteína del síndrome de Wiskott-Aldrich (WASp). Reportamos el caso clínico de un paciente de 18 meses con diagnóstico de Wiskott-Aldrich que no presentaba donante antígeno leucocitario humano (HLA) idéntico y recibió un trasplante de células progenitoras hematopoyéticas (TCPH) con donante familiar haploidéntico. La profilaxis para enfermedad de injerto contra huésped incluyó ciclofosfamida (PT-Cy). El quimerismo del día +30 fue 100 % del donante y la evaluación postrasplante de la expresión de la proteína WAS fue normal. Actualmente, a 32 meses del trasplante, presenta reconstitución hematológica e inmunológica y quimerismo completo sin evidencia de enfermedad injerto contra huésped. El TCPH haploidéntico con PT-Cy se mostró factible y seguro en este caso de síndrome de WiskottAldrich en el que no se disponía de un donante HLA idéntico.

Wiskott-Aldrich syndrome (WAS) is an X-linked genetic disorder caused by mutations in the gene that encodes the Wiskott-Aldrich syndrome protein (WASp). Here, we report the clinical case of an 18-month-old boy diagnosed with Wiskott-Aldrich syndrome, who did not have an HLA-matched related or unrelated donor and was treated successfully with a hematopoietic stem cell transplant (HSCT) from a haploidentical family donor. Graft-versus-host disease (GvHD) prophylaxis included post-transplant cyclophosphamide (PT-Cy). At day +30, the peripheral blood-nucleated cell chimerism was 100% and the WAS protein had a normal expression. Currently, at month 32 post-transplant, the patient has hematological and immune reconstitution and complete donor chimerism without evidence of GvHD. HSCT with PT-Cy was a feasible and safe option for this patient with WAS, in which an HLA matched donor was not available.

A comparative assessment of air pollutants of smog in wagah border and other sites in Lahore, Pakistan / Uma avaliação comparativa de poluentes do ar do smog na fronteira de wagah e outros sites em Lahore, Paquistão

Abstract Smog has become the fifth season of Pakistan especially in Lahore city. Increased level of air pollutants (primary and secondary) are thought to be responsible for the formation of smog in Lahore. Therefore, the current study was carried out for the evaluation of air pollutants (primary and secondary) of smog in Wagah border particularly and other sites (Jail road, Gulburg) Lahore. For this purpose, baseline data on winter smog from March to December on primary and secondary air pollutants and meteorological parameters was collected from Environmental Protection Department and Pakistan Meteorological Department respectively. Devices being used in both departments for analysis of parameters were also studied. Collected data was further statistically analyzed to determine the correlation of parameters with meteorological conditions and was subjected to air quality index. According to results, PM 10 and PM 2.5 were found very high above the NEQS. NOx concentrations were also high above the permissible limits whereas SO2 and O3 were found below the NEQS thus have no roles in smog formation. Air Quality Index (AQI) of pollutants was PM 2.5(86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) and SO2 (10-95). AQI of PM 2.5 remained between moderate to very unhealthy levels. AQI of PM 10 remained between good to hazardous levels. AQI of NOx remained between good to unhealthy for sensitive groups' levels. AQI of O3 and SO2 remained between good to moderate levels. Pearson correlation showed that every pollutant has a different relation with different or same parameters in different areas. It is concluded from the present study that particulate matter was much more responsible for smog formation. Although NOx also played role in smog formation. So there is need to reduce sources of particulate matter and NOx specifically in order to reduce smog formation in Lahore.

Resumo Smog tornou-se a quinta estação do Paquistão, especialmente na cidade de Lahore. Acredita-se que o aumento do nível de poluentes atmosféricos (primários e secundários) seja responsável pela formação de poluição atmosférica em Lahore. Portanto, o presente estudo foi realizado para a avaliação dos poluentes atmosféricos (primários e secundários) do smog na fronteira de Wagah em particular e em outros locais (Jail road, Gulburg) Lahore. Para este propósito, os dados de referência sobre a poluição atmosférica de inverno de março a dezembro sobre poluentes atmosféricos primários e secundários e parâmetros meteorológicos foram coletados do Departamento de Proteção Ambiental e do Departamento Meteorológico do Paquistão, respectivamente. Dispositivos sendo usados ​​em ambos os departamentos para análise de parâmetros também foram estudados. Os dados coletados foram posteriormente analisados ​​estatisticamente para determinar a correlação dos parâmetros com as condições meteorológicas e foram submetidos ao índice de qualidade do ar. De acordo com os resultados, PM 10 e PM 2,5 foram encontrados muito acima do NEQS. As concentrações de NOx também estavam muito acima dos limites permitidos, enquanto SO2 e O3 foram encontrados abaixo do NEQS, portanto, não têm papéis na formação de smog. O índice de qualidade do ar (AQI) de poluentes foi PM 2,5 (86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) e SO2 (10-95). O AQI de PM 2,5 permaneceu entre níveis moderados a muito prejudiciais à saúde. O AQI de PM 10 permaneceu entre níveis bons e perigosos. AQI de NOx permaneceu entre bom e não saudável para os níveis de grupos sensíveis. O AQI de O3 e SO2 permaneceu entre níveis bons a moderados. A correlação de Pearson mostrou que cada poluente tem uma relação diferente com parâmetros diferentes ou iguais em áreas diferentes. Conclui-se do presente estudo que o material particulado foi muito mais responsável pela formação de smog. Embora o NOx também tenha desempenhado um papel na formação do smog. Portanto, é necessário reduzir as fontes de partículas e NOx, especificamente para reduzir a formação de smog em Lahore.

Headache as the most prevalent post-vaccination adverse event after Covid-19 vaccination / Dor de cabeça como evento adverso pós-vacinação mais prevalente após a vacinação contra Covid-19

BACKGROUND: In 2020, the first vaccines were approved, according to the WHO. However, speculations arose regarding their efficacy and post-vaccination adverse events (AEFV). OBJECTIVE: To evaluate the prevalence of headache as AEFI from the SARSCoV-2 vaccine in Piauí, Brazil. METHODS: This is a quantitative, observational, cross-sectional, and prevalence study. Data were provided by the Post-Vaccination Adverse Event Information System (SI-AEFV), from reported cases from January to September 2021. Data were analyzed, and the research was approved by the UFPI Research Ethics Committee. RESULTS: A total of 2,008 cases were analyzed. Headache was reported in 752 cases (27.99%) as an AEFV after vaccination against SARS-CoV-2. In most cases, patients were from Teresina (67.62%), of brown race/ethnicity (52.67%), female (79.00%), and the majority were not healthcare professionals (54.27%). The most common age of patients, with the original data, was 33 years. After data correction, the most common age was 28 years. The majority of these cases were not severe (96.44%), and the majority of cases were associated with the first dose of the Covid-19-Covishield-Oxford/AstraZeneca vaccine (43.18%).CONCLUSION: Thus, it is concluded from the partial analysis of the results that headache is the most common adverse event after vaccination against SARS-CoV-2. The profile of patients with the most notifications was brown women aged 30 to 40 years who received the first dose of the Covid-19-Covishield-Oxford/AstraZeneca vaccine. Regarding the severity of events, the vast majority were considered non-severe, and no deaths were mentioned, demonstrating the safety of immunobiologicals.

FUNDAMENTO: Em 2020, foram aprovadas as primeiras vacinas, segundo a OMS. No entanto, surgiram especulações quanto à sua eficácia e eventos adversos pós-vacinais (EAPV). OBJETIVO: Avaliar a prevalência de cefaleia como EAPV da vacina SARSCoV-2 no Piauí, Brasil. MÉTODOS: Trata-se de um estudo quantitativo, observacional, transversal e de prevalência. Os dados foram fornecidos pelo Sistema de Informação de Eventos Adversos Pós-Vacinação (SI-AEFV), dos casos notificados no período de janeiro a setembro de 2021. Os dados foram analisados ​​e a pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da UFPI. RESULTADOS: Foram analisados ​​2.008 casos. Cefaleia foi relatada em 752 casos (27,99%) como EAPV após vacinação contra SARS-CoV-2. Na maioria dos casos, os pacientes eram procedentes de Teresina (67,62%), de raça/etnia parda (52,67%), do sexo feminino (79,00%) e a maioria não era profissional de saúde (54,27%). A idade mais comum dos pacientes, com os dados originais, era de 33 anos. Após correção dos dados, a idade mais comum foi 28 anos. A maioria desses casos não foi grave (96,44%), e a maioria dos casos esteve associada à primeira dose da vacina Covid-19-Covishield-Oxford/AstraZeneca (43,18%).CONCLUSÃO: Assim, conclui-se a partir da análise parcial dos resultados de que cefaleia é o evento adverso mais comum após vacinação contra SARS-CoV-2. O perfil dos pacientes com mais notificações foi de mulheres pardas com idade entre 30 e 40 anos que receberam a primeira dose da vacina Covid-19-Covishield-Oxford/AstraZeneca. Quanto à gravidade dos eventos, a grande maioria foi considerada não grave e não foram mencionados óbitos, demonstrando a segurança dos imunobiológicos.

Activation of M1 muscarinic acetylcholine receptors by proline-rich oligopeptide 7a (

Background: The bioactive peptides derived from snake venoms of the Viperidae family species have been promising as therapeutic candidates for neuroprotection due to their ability to prevent neuronal cell loss, injury, and death. Therefore, this study aimed to evaluate the cytoprotective effects of a synthetic proline-rich oligopeptide 7a (PRO-7a; <EDGPIPP) from Bothrops jararaca snake, on oxidative stress-induced toxicity in neuronal PC12 cells and astrocyte-like C6 cells. Methods: Both cells were pre-treated for four hours with different concentrations of PRO-7a, submitted to H2O2-induced damage for 20 h, and then the oxidative stress markers were analyzed. Also, two independent neuroprotective mechanisms were investigated: a) L-arginine metabolite generation via argininosuccinate synthetase (AsS) activity regulation to produce agmatine or polyamines with neuroprotective properties; b) M1 mAChR receptor subtype activation pathway to reduce oxidative stress and neuron injury. Results: PRO-7a was not cytoprotective in C6 cells, but potentiated the H2O2-induced damage to cell integrity at a concentration lower than 0.38 μM. However, PRO-7a at 1.56 µM, on the other hand, modified H2O2-induced toxicity in PC12 cells by restoring cell integrity, mitochondrial metabolism, ROS generation, and arginase indirect activity. The α-Methyl-DL-aspartic acid (MDLA) and L-NΩ-Nitroarginine methyl ester (L-Name), specific inhibitors of AsS and nitric oxide synthase (NOS), which catalyzes the synthesis of polyamines and NO from L-arginine, did not suppress PRO-7a-mediated cytoprotection against oxidative stress. It suggested that its mechanism is independent of the production of L-arginine metabolites with neuroprotective properties by increased AsS activity. On the other hand, the neuroprotective effect of PRO-7a was blocked in the presence of dicyclomine hydrochloride (DCH), an M1 mAChR antagonist. Conclusions: For the first time, this work provides evidence that PRO-7a-induced neuroprotection seems to be mediated through M1 mAChR activation in PC12 cells, which reduces oxidative stress independently of AsS activity and L-arginine bioavailability.(AU)

Effect of Water and Chlorhexidine with Different Pressures of Oral Irrigation Device on the Surface Roughness and Topography of Giomer

Abstract Objective: To evaluate the effect of different pressures of an oral irrigation device (OID) and the irrigation solution type on the surface roughness of the giomer restorative material. Material and Methods: In this in vitro study, disk-shaped giomer samples were fabricated and assigned to 5 groups (n=23): Group 1, storage in distilled water (control); Group 2, OID #7 pressure/ water; Group 3, OID #10 pressure/ water; Group 4, OID #7 pressure/ 0.05% CHX; Group 5, OID #10 pressure/ 0.05% CHX. The samples' treatment simulated a one-year application of OID. Surface roughness (Ra) and topography of the giomer were evaluated using profilometry and scanning electron microscopy. The data were analyzed with Paired t-test, Tukey, and ANOVA tests (α=0.05). Results: The Ra of the samples increased significantly after treatment with OID (p<0.001). The roughness increase in groups with a pressure of 10 was higher than those with a pressure of 7 (p<0.001). The effect of pressure on surface changes was significant (p<0.001). However, the solution type and the cumulative effect of these two factors were insignificant (p=0.08 and p=0.43, respectively). Conclusion: Oral irrigation device with both solutions significantly increased the surface roughness and topographic changes of the giomer. The severity of these changes was related to the device's pressure.

Desensitizing Agent Previously Applied During In-Office Bleaching: A Double-Blind Randomized Clinical Trial

Abstract Objective: To compare the clinical effect of two desensitizing agents used before the application of a bleaching gel based on 35% hydrogen peroxide (HP). Material and Methods: 30 patients were selected, and two desensitizing agents with different mechanisms of action were applied: Fluorine Neutral 2% (FN), which acts by blocking dentinal canaliculi while Potassium Nitrate 5% with 2% Sodium Fluoride (PN/SF) that acts in nerve transmission and blockade. Desensitizers were used before the application of 35% HP. For whitening, three clinical sessions were performed, with an interval of seven days, with three applications of the bleaching gel for 15 minutes, totaling 45 minutes/session. Tooth sensitivity (TS) was assessed with the numerical analog scale, and a spectrophotometer was used to obtain the color variation (ΔE). ΔE were submitted to ANOVA and Tukey test (p<0.05), and TS data were submitted to a two-way ANOVA analysis. Results: For sensitivity experience, the Tukey test indicated differences between PN/SF and the placebo I, but there was no statistically significant difference between FN and the placebo II. The TS was lower when the desensitizing gel was used during the bleaching procedure compared to after treatment, regardless of the desensitizing agents. Conclusion: PN/SF before in-office tooth bleaching can reduce TS intensity, and the use of desensitizing gel before bleaching did not affect the bleaching efficacy.

Alterações oculares decorrentes de picada de abelha na córnea / Ocular changes due to corneal bee sting

RESUMO O propósito deste estudo foi reportar as alterações oculares observadas após picada de abelha com ferrão retido na córnea. Destacamos o tratamento e o desfecho de uma lesão de córnea incomum e sua patogênese. Trata-se de relato de caso e revisão da literatura de lesões oculares por picada de abelha. Paciente do sexo feminino, 63 anos, procurou atendimento oftalmológico de urgência devido à picada de abelha na córnea do olho direito há 6 dias. Queixava-se de embaçamento visual, dor e hiperemia ocular. Apresentou acuidade visual de vultos no olho afetado. Ao exame, notaram-se hiperemia moderada de conjuntiva bulbar, edema corneano com dobras de Descemet e presença do ferrão alojado na região temporal, no estroma profundo da córnea. A paciente foi internada para ser abordada no centro cirúrgico sob anestesia geral. Durante a cirurgia, o ferrão teve que ser retirado via câmara anterior, mediante a realização de uma paracentese e uma lavagem da câmara anterior, com dupla via e solução salina balanceada. Ainda não existe na literatura um tratamento padrão na abordagem de pacientes com lesões oculares por picada de abelha, sendo importantes a identificação e o reconhecimento precoce de possíveis complicações que ameacem a visão.

ABSTRACT The purpose of this study was to report the ocular changes observed after a bee sting with a stinger retained in the cornea. We show the treatment and outcome of an unusual corneal injury and its pathogenesis. This is a case report and literature review of ocular injuries caused by bee stings. A 63-year-old female patient sought emergency ophthalmic care because of a bee sting on the cornea of her right eye six days before. She complained of blurred vision, pain, and ocular hyperemia. She had glare sensitivity on visual acuity in the affected eye. Examination revealed moderate hyperemia of the bulbar conjunctiva, corneal edema with Descemet's folds and a stinger lodged in the temporal region, in the deep stroma of the cornea. The patient was admitted to the operating room under general anesthesia. During surgery, the stinger had to be removed via the anterior chamber, by performing a paracentesis and washing the anterior chamber with a double flushing and balanced saline solution. There is still no standard treatment in the literature for patients with eye injuries caused by bee stings, and early identification and recognition of possible sight-threatening complications is important.

Calidad de vida y toxicidad financiera de los receptores de trasplantes de células madre hematopoyéticas en COVID-19 / Quality of life and financial toxicity of hematopoietic stem cell transplant recipients in COVID-19 / Qualidade de vida e toxicidade financeira dos transplantados de células-tronco hematopoéticas na COVID-19

Objetivo: evaluar y correlacionar la calidad de vida y la toxicidad financiera de pacientes adultos sometidos a trasplante de células madre hematopoyéticas durante el período de la pandemia de COVID-19. Método: estudio observacional, analítico, realizado con 35 pacientes en un hospital de referencia para trasplante en Latinoamérica. Para la recolección de datos, se utilizaron los cuestionarios Functional Assessment Cancer Therapy Bone Marrow Transplantation y el COmprehensive Score for financial Toxicity. Para el análisis de los datos se utilizaron las pruebas de correlación de Spearman y Mann-Whitney. Resultados: la calidad de vida general durante la COVID-19 mostró un puntaje bajo (67,09/108) con mayor deterioro en el bienestar funcional (14,47/28), bienestar social (16,76/28) y preocupaciones adicionales (23,41/40). Los promedios del grupo alogénico fueron inferiores a los del grupo autólogo en todos los dominios, presentando diferencia significativa en relación a preocupaciones adicionales (p=0,01) y en el índice de evaluación del tratamiento (p=0,04). Se consideró que la toxicidad financiera tenía un impacto leve (22.11/44). Se observó una relación, aunque no significativa, entre la calidad de vida y la toxicidad financiera (p=0,051). Conclusión: la calidad de vida de la muestra fue baja; existe una correlación entre la calidad de vida y la toxicidad financiera, aunque no significativa. Cuanto mayor es la toxicidad financiera, menor es la calidad de vida.

Objective: to evaluate and correlate the quality of life and financial toxicity of adult patients undergoing hematopoietic stem cell transplantation during the COVID-19 pandemic. Method: observational, analytical study, carried out with 35 patients in a reference hospital for transplantation in Latin America. For data collection, the Functional Assessment Cancer Therapy Bone Marrow Transplantation and COmprehensive Score for Financial Toxicity questionnaires were used. Spearman and Mann-Whitney correlation tests were used for data analysis. Results: general quality of life during COVID-19 had a low score (67.09/108) with greater impairment in functional well-being (14.47/28), social well-being (16.76/28) and additional concerns (23.41/40). The means of the allogeneic group were lower than those of the autologous group in all domains, showing a significant difference in relation to additional concerns (p=0.01) and in the treatment evaluation index (p=0.04). Financial toxicity was considered to have a slight impact (22.11/44). There was a relationship, albeit not significant, between quality of life and financial toxicity (p=0.051). Conclusion: the quality of life of the sample was low; there is a correlation between quality of life and financial toxicity, although not significant. The higher the financial toxicity, the lower the quality of life.

Early vs. Standard Loop Ileostomy Closure: An Unmatched Case-Control Study / Cierre Temprano vs Estándar de Ileostomía en Asa. Estudio de Casos y Controles no Emparejado

SUMMARY: Early closure of a loop ileostomy (ECI) is a relatively new practice, for which there is insufficient evidence regarding its effectiveness in relation to closure at conventional times. The aim of this study was to report postoperative complications (POC) and hospital mortality in patients with loop ileostomy (LI) who underwent ECI, compared with patients with LI who underwent late closure. Un- matched case-control study. Patients with LI who underwent surgery at Clínica RedSalud Mayor Temuco (2010-2022) were included. Cases were defined as patients with LI who underwent early closure and controls as subjects who underwent closure at the usual times. No matching was performed, but a 1:1 relationship between cases and controls was considered. Outcome variables were postoperative complications and hospital mortality. Other variables of interest were surgical time and hospital stay. Descriptive statistics were applied with calculation of proportions and measures of central tendency. Subsequently, t-test and Pearson Chi2 for comparison of averages and proportions was applied, and odds ratios and their respective 95 % CI were calculated. In this study 39 patients with AI were operated on (18 cases and 21 controls). Age and BMI average of the studied subjects was 71.3±7.1 years and 27.3±19.8 kg/m2 respectively. Mean LI closure time, surgical time, and hospitalization were: 10.0±0.7 months; 62.5±10.6min; 3.8±0.1 days respectively. POC were only surgical site infections. Three in cases (16.7 %) and 3 in controls (14.3 %). No anastomotic dehiscence or hospital mortality was observed in either cases or controls. There were no differences in comorbidities or surgical site infection between cases and controls (OR of 0.6 and 1.2 respectively) In this experience, the results of performing the CTI were similar to the late closing in relation to the variables studied.

El cierre temprano de una ileostomía en asa (IA), es una práctica relativamente nueva, sobre la que no hay suficiente evidencia respecto de su efectividad en relación con el cierre en tiempos convencionales. El objetivo de este estudio fue verificar diferencias en la tasa de complicaciones postoperatorias (CPO) y de mortalidad hospitalaria en pacientes con IA sometidos a cierre temprano comparados con pacientes con IA sometidos a cierre tardío. Estudio de casos y controles sin emparejamiento. Se incluyeron pacientes con IA que fueron sometidos a cirugía en la Clínica RedSalud Mayor Temuco (2010-2022). Los casos se definieron como pacientes con IA sometidos a cierre temprano y los controles como sujetos con IA sometidos a cierre en tiempos habituales. No se realizó emparejamiento. Se consideró una relación 1:1 entre casos y controles. Las variables de resultado fueron CPO y mortalidad hospitalaria. Otras variables de interés fueron: tiempo quirúrgico y hospitalización. Se aplicó estadísticas descriptivas (cálculo de proporciones y medidas de tendencia central). Posteriormente, se aplicó prueba t-test y Chi2 para comparación de promedios y proporciones; y se calcularon odds ratios e intervalos de confianza del 95 %. Se operaron 39 pacientes con IA (18 casos y 21 controles). El promedio de edad e IMC fue 71,3±7,1 años y 27,3±19,8 kg/m2, respectivamente. El tiempo promedio de cierre de IA, tiempo quirúrgico y hospitalización fueron: 10,0±0,7 meses; 62,5±10,6 minutos; 3,8±0,1 días, respectivamente. Las CPO fueron infecciones del sitio quirúrgico (3 casos; 16,7 % y 3 controles; 14,3 %). No se observó dehiscencia anastomótica ni mortalidad hospitalaria en casos ni controles. No hubo diferencias en comorbilidades ni en infecciones del sitio quirúrgico entre casos y controles (OR de 0,6 y 1,2, respectivamente). No se evidenciaron diferencias entre realizar cierre temprano o tardío de IA, respecto de las variables CPO y de mortalidad hospitalaria.
