ABSTRACT

Introducción: los beneficios de la ventilación asistida ajustada neuronalmente (NAVA) en los recién nacidos prematuros son inciertos. El objetivo de este estudio fue explorar si la NAVA no invasiva (NIV) era más beneficiosa para los recién nacidos prematuros que la presión positiva continua nasal (NCPAP). Diseño del estudio: metanálisis de tres ensayos clínicos: dos ensayos controlados aleatorizados y un estudio de grupos cruzados. Se comparó la NAVA-NIV con la NCPAP y se informó sobre el fracaso del tratamiento, la mortalidad y los eventos adversos como resultados principales. Resultados: tres estudios con 173 pacientes (89 recibieron NAVA-NIV) cumplieron los criterios de inclusión en este metanálisis. No se observaron diferencias en el fracaso del tratamiento entre la NAVA-NIV y la NCPAP (razón de riesgos [RR] = 1,09; intervalo de confianza [IC] del 95 % = 0,65-1,84; diferencia de riesgos = 0,02; IC95% = -0,10-0,14; I2 = 33 %; P = 0,23). De manera similar, no hubo diferencias en la mortalidad (RR = 1,52; IC95% = 0,51-4,52; no aplica heterogeneidad). En comparación con la NCPAP, la NAVA-NIV redujo significativamente el uso de cafeína (RR = 0,85; IC 95% = 0,74-0,98; I2 = 71 %; P = 0,03). Conclusiones: en comparación con la NCPAP, no hay evidencia suficiente para sacar una conclusión sobre los beneficios o daños de la NAVA-NIV en los recién nacidos prematuros. Los hallazgos de esta revisión deben confirmarse en ensayos clínicos con una metodología rigurosa y potencia adecuada


Introduction: The benefits of neurally adjusted ventilatory assist (NAVA) in preterm infants are unclear. This study aimed to explore if noninvasive NAVA is more beneficial for preterm infants than nasal continuous positive airway pressure (NCPAP). Study design: Meta-analysis was performed in three clinical trials comprising two randomized controlled trials and one crossover study. We compared NIV-NAVA and NCPAP and reported treatment failure, mortality, and adverse events as the primary outcomes. Results: Three studies including 173 patients (89 of whom underwent NIV-NAVA) were eligible for this meta-analysis. This review found no difference in treatment failure between NIV-NAVA and NCPAP (RR 1.09, 95% CI 0.65 to 1.84; RD 0.02, 95% CI -0.10-0.14; I2=33%, P=0.23). Similarly, there was no difference in mortality (RR 1.52, 95% CI 0.51-4.52, heterogeneity not applicable). Compared with NCPAP, NIV-NAVA significantly reduced the use of caffeine (RR 0.85, 95% CI 0.74-0.98, I2=71%, P=0.03). Conclusions: Compared with NCPAP, there is insufficient evidence to conclude on the benefits or harm of NIV-NAVA therapy for preterm infants. The findings of this review should be confirmed using methodologically rigorous and adequately powered clinical trials.

ABSTRACT

Non-small cell lung cancer (NSCLC) is one of the most severe malignant tumors worldwide. Lobectomy and systematic nodal dissection remain the standard treatment for stageⅠNSCLC. Stereotactic body radiotherapy (SBRT) has become the standard treatment for medically inoperable patients. Though the prognosis of stage Ⅰ NSCLC patients is generally good, there are still about 20% of patients with local recurrence and distant metastasis. There is significant heterogeneity in the prognosis and failure phenotype of patients, which cannot be precisely distinguished by the pathological TNM classification system. Identification of the risk factors for the prognosis of patients with stage Ⅰ NSCLC is a key step to realize the treatment from experience to precision. Screening the high-risk patients will facilitate to individually develop the adjuvant therapy strategy after surgery or SBRT and improve the overall curative effect. There are many factors that are significantly related to the prognosis of stage Ⅰ NSCLC including individual factors such as gender, age, and systemic inflammatory biomarkers; treatment-related factors such as the extent of surgical resection of the primary tumor and lymph nodes, the choice of different radiation rays, and different dose fractionation; and tumor-related factors such as imaging information, pathology information; and molecular biology information. This review will analyze the treatment failure phenotype and prognostic factors of stageⅠ NSCLC in various perspectives such as individual-, tumor- and treatment-related factors.

ABSTRACT

OBJECTIVES@#To systematically evaluate the efficacy and safety of bosentan in the treatment of persistent pulmonary hypertension of the newborn (PPHN).@*METHODS@#Chinese Journal Full-text Database, Weipu Database, Wanfang Data, China Biology Medicine disc, PubMed, Web of Science, Embase, and Cochrane Library were searched for literature on bosentan in the treatment of PPHN published up to August 31, 2021.@*RESULTS@#A total of 8 randomized controlled trials were included for Meta analysis. The results of the Meta analysis showed that compared with the control group, the bosentan treatment group had a significantly lower treatment failure rate (RR=0.23, P<0.001), a significantly greater reduction in pulmonary artery pressure [mean difference (MD)=-11.79, P<0.001)], significantly greater increases in oxygen partial pressure (MD=10.21, P=0.006) and blood oxygen saturation (MD=8.30, P<0.001), and a significantly shorter length of hospital stay (MD=-1.35, P<0.001). The descriptive analysis showed that the bosentan treatment group had a lower degree of tricuspid regurgitation than the control group after treatment. The main adverse reactions of bosentan treatment included abnormal liver function, anemia and edema. The results of subgroup analysis based on treatment regimen, research area, and drug dose were consistent with those before stratification.@*CONCLUSIONS@#Bosentan is effective in the treatment of PPHN. However, when using bosentan, attention should be paid to adverse reactions such as abnormal liver function.

ABSTRACT

RESUMEN: En condiciones normales, la mandíbula y sus estructuras anatómicas (dientes, musculatura, piel), son inervadas por los ramos de la tercera división del nervio trigémino (nervio mandibular), sin embargo, existen reportes que evidencian inervación suplementaria de los dientes inferiores y la zona del ángulo mandibular. Lo último podría ser responsable del fracaso del bloqueo nervioso con anestesia local. El objetivo principal de esta investigación fue revisar artículos que describen la participación de otros nervios como el milohioideo y los ramos superficiales del plexo cervical, los cuales pueden ingresar a la mandíbula a través de forámenes ubicados a lo largo de su arquitectura. Para esto, se realizó una revisión narrativa de la literatura científica, en inglés y español, desde el año 1971 hasta el año 2019, utilizando las plataformas digitales PubMed, EBSCO, Cochrane library, Scielo y Google Scholar, literatura gris y además de una búsqueda manual. Acorde a los resultados de la revisión, se confirma la existencia de fracasos de técnicas anestésicas mandibulares debido a la inervación accesoria de la mandíbula y de los dientes inferiores, donde los tres principales nervios revisados tienen incidencia en este postulado. Finalmente se plantea un orden de ejecución para realizar la infiltración de anestésico local en la mandíbula para lograr un bloqueo exitoso durante los procedimientos odontológicos que la requieran.


SUMMARY: Under normal conditions, the mandible and its anatomical structures (teeth, muscles, skin) are innervated by the branches of the third division of the trigeminal nerve (mandibular nerve), however, there are reports that show supplementary innervation of the lower teeth and the mandibular angle area. The latter could be responsible for the failure of the nerve block under local anesthesia. The main objective of this research; is to review articles that describe the participation of other nerves such as the mylohyoid nerve, and the superficial branches of the cervical plexus, which can enter the mandible through foramina located along its architecture. For this, a narrative review of the scientific literature was carried out, in English and Spanish, from 1971 to 2019, using the digital platforms PubMed, EBSCO, Cochrane library, Scielo and Google Scholar, gray literature and in addition to a search Handbook. According to the results of the review, the existence of the failures of the mandibular anesthetic techniques due to the accessory innervation of the mandible and the lower teeth is confirmed, where the three main nerves reviewed have an impact on this postulate. In conclusion, an order of execution is proposed to perform local anesthetic infiltration into the jaw to achieve a successful block during dental procedures that require it.

ABSTRACT

OBJECTIVE@#To develop and validate a risk prediction model of treatment failure in patients with peritoneal dialysis-associated peritonitis (PDAP).@*METHODS@#We retrospectively analyzed the data of patients undergoing peritoneal dialysis (PD) in 3 dialysis centers in Jilin Province who developed PDAP between January 1, 2013 and December 31, 2019. The data collected from the Second Hospital of Jilin University and Second Division of First Hospital of Jilin University) were used as the training dataset and those from Jilin Central Hospital as the validation dataset. We developed a nomogram for predicting treatment failure using a logistic regression model with backward elimination. The performance of the nomogram was assessed by analyzing the C-statistic and the calibration plots. We also plotted decision curves to evaluate the clinical efficacy of the nomogram.@*RESULTS@#A total of 977 episodes of PDAP were included in the analysis (625 episodes in the training dataset and 352 episodes in the validation dataset). During follow-up, 78 treatment failures occurred in the training dataset and 35 in the validation dataset. A multivariable logistic regression prediction model was established, and the predictors in the final nomogram model included serum albumin, peritoneal dialysate white cell count on day 5, PD duration, and type of causative organisms. The nomogram showed a good performance in predicting treatment failure, with a C-statistic of 0.827 (95% CI: 0.784-0.871) in the training dataset and of 0.825 (95% CI: 0.743-0.908) in the validation dataset. The nomogram also performed well in calibration in both the training and validation datasets.@*CONCLUSION@#The established nomogram has a good accuracy in estimating the risk of treatment failure in PDAP patients.

ABSTRACT

Abstract Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF).We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal

ABSTRACT

Abstract Introduction Colorectal cancer is the second most common type of cancer and the third leading cause ofmortality due to cancers. Anastomosis leak after proctectomy is a dangerous complication that must be managed carefully. The aim of the present study was to assess the procedure of resection and pull-through of the new rectum after anastomosis leak in patients after proctectomy. Methods and Materials This was a cross-sectional study. Patients who visited the Firoozgar Hospital between 2015 and 2018 for rectal cancer surgery and had anastomosis leak entered the study. All patients underwent resection of the residue of rectum and pull-through of colon. Results In the present study, out of the 110 cases who underwent proctectomy, 12 patients with postoperative anastomosis leak were reported. Five (41.7%) were male and 7 (58.3%) were female. Themean age of the patients was 41.5 ± 4.3 years (33-51). Resection of the new rectum and pull-through anastomosis were performed for these 12 patients. No major intraoperative complication occurred. Postoperative course was uneventful in all patients. Discussion Resection of residue of rectum and pull-through in patients with anastomosis leak can be done after rectal cancer surgery. This method is superior to abdominopelvic resection in many aspects, especially regarding accessibility to the new rectum by rectal exam or endosonography to assess recurrence or a relative continence after closure of ostomy.


Resumo Introdução O câncer colorretal é o segundo tipo de câncer mais comum, e a terceira principal causa de mortalidade por câncer. O vazamento da anastomose após a proctectomia é uma complicação perigosa, que deve ser tratada com cuidado. O objetivo do presente estudo foi avaliar o procedimento de ressecção e abaixamento do novo reto após vazamento de anastomose em pacientes submetidos à proctectomia. Métodos e Materiais Este foi um estudo transversal que incluiu pacientes que compareceram ao Firoozgar Hospital entre 2015 e 2018 submetidos a cirurgia de câncer retal e com vazamento de anastomose. Todos os pacientes foram submetidos a ressecção do resíduo do reto e abaixamento do cólon. Resultados No presente estudo, dos 110 casos submetidos a proctectomia, 12 pacientes tiveram vazamento de anastomose pós-operatório: 5 (41,7%) do sexo masculino e 7 (58,3%) do sexo feminino. A idade média dos pacientes foi de 41,5 ± 4,3 anos (gama: 33 a 51 anos). A ressecção do reto novo e a anastomose por abaixamento foram realizadas nesses 12 pacientes. Nenhuma complicação intraoperatória mais grave ocorreu. No pós-operatório, não houve intercorrências em nenhum dos pacientes. Discussão A ressecção de resíduo retal e o abaixamento em pacientes com vazamento de anastomose pode ser feita após cirurgia de câncer retal. Este método é superior à ressecção abdominopélvica em muitos aspectos, especialmente quanto à acessibilidade ao novo reto por exame retal ou endossonografia para avaliar a recorrência ou uma continência relativa após o fechamento da ostomia.

ABSTRACT

OBJECTIVE@#To analyze the efficacy of CCLG-ALL-2008 protocol and the related factors of treatment failure in children with acute lymphoblastic leukemia (ALL).@*METHODS@#The clinical data of 400 children newly-diagnosed ALL in Children's Hospital of Soochow University from March 1, 2008 to December 31, 2012 was retrospectively analyzed. All the children accepted CCLG-ALL-2008 protocol, and were followed-up until October 2019. The dates of relapse, death and causes of death were recorded. Treatment failure was defined as relapse, non-relapse death, and secondary tumor.@*RESULTS@#Following-up for 10 years, there were 152 cases relapse or non-relapse death, the treatment failure rate was 38%, including 122 relapse (80.3%), 30 non-relapse deaths (19.7%) which included 7 cases (4 cases died of infection and 3 cases died of bleeding) died of treatment (23.3% of non-relapse deaths), 8 cases died of minimal residual disease (MRD) continuous positive (26.7% of non-relapse deaths) and 15 cases died of financial burden (50% of non-relapse deaths). According to the relapse stage, 37 cases (30%) in very early stage, 38 cases (31%) in early stage, and 47 cases (39%) in late stage, while according to the relapse site, 107 cases relapsed in bone marrow, 3 cases in testis, 3 cases in central nervous system (CNS), 5 cases in bone marrow plus testis and 4 cases in bone marrow plus CNS. Bone marrow relapse was the main cause of death in 89 cases, followed by nervous system. Initially diagnosed WBC count (≥50×10@*CONCLUSION@#Relapse is the main cause of treatment failure in children with ALL. The initially diagnosed WBC count, immunophenotype and MRD at week 12 were the independent prognostic factors for relapse of the patients. Financial burden accounts for a large proportion of non-relapse death.

ABSTRACT

Sub-therapeutic doses, shorter duration of therapy, female gender, bacteremia, and renal impairment were among independent predictors of polymyxin B treatment failure. In this study, we found an association between inappropriate doses of polymyxin B (<15000 or >25000 unit/kg/day) and renal impairment. Inappropriate doses of polymyxin B were significantly associated with CrCl 20-50 mL/min (p = 0.021, ORadj 6.660, 95% CI 1.326, 33.453) and CrCl <20 mL/min (p = 0.001, ORadj 22.200, 95% CI 3.481, 141.592). By conducting sub-group analysis only using subjects with appropriate dosage, renal impairment was not associated with polymyxin B treatment failure, thus indicating that treatment failure was due to an inappropriate dose of polymyxin B, rather than renal impairment. In conclusion, renal impairment was not directly associated with treatment failure but was due to an inappropriate dosage of polymyxin B after renal adjustment

ABSTRACT

O objetivo deste trabalho foi analisar os aspectos emocionais presentes no processo de reprodução humana assistida (RHA), por meio de uma revisão interativa da literatura. As bases de dados utilizadas foram PubMed, BVS e Periódicos Capes, com os descritores "infertility" AND "reproductive techniques" AND "emotions". Foram incluídos e analisados 24 artigos dos últimos cinco anos (2015 a 2020). Os resultados indicam que existem diversos sentimentos negativos que permeiam os casais infé rteis, especialmente quando existem falhas no tratamento. O apoio social durante o tratamento em RHA melhora a qualidade de vida do casal e diminui o sofrimento emocional. As estratégias de enfrentamento utilizadas pelos casais inférteis e as intervenções terapêuticas também foram avaliadas como positivas para o manejo do estresse, da ansiedade e da depressão. As diferenças de gênero apareceram nos estudos e reiteram a relevância das relações de gênero, indicando a necessidade de intervenções diferentes para homens e mulheres.(AU)


The aim of this work was to analyze the emotional aspects present in the assisted human reproduction (RHA) process, through an interactive literature review. The databases used were PUBMED, BVS and CAPES journals, with the descriptors "infertility" AND « reproductive techniques" AND "emotions." 24 articles from the last five years (2015 to 2020) were included and analyzed. The results indicate that there are several negative feelings that permeate infertile couples, especially when treatment failures, social support during RHA treatment improves the couple's quality of life and reduces emotional distress. The coping strategies used by infertile couples and interventions therapeutics were also evaluated as positive for the management of stress, anxiety and depression. The gender differences appeared in the studies and reiterate the relevance of gender relations, indicating the need for different interventions for men and women.(AU)

ABSTRACT

Resumen Introducción: Cargas virales (CV) entre 20-200 copias/mL se consideran cargas virales de bajo grado (CVBG). Su implicancia clínica y manejo no han sido definidos. Objetivo: Evaluar el impacto de CVBG en el riesgo de desarrollo posterior de fallo virológico (FV). Pacientes y Métodos: Se incluyeron pacientes ≥ 18 años, desde enero de 2009 a diciembre de 2019, con infección por VIH-1 con CV< 20 copias/mL, por un mínimo de seis meses y/o en dos muestras consecutivas bajo tratamiento anti-retroviral . Se realizó seguimiento de las CV estrati ficándolas: CV < 20 copias/mL, CVBG (20-50 copias/mL y 51-200 copias/mL) y FV. Mediana de seguimiento 25 meses (IQR 15-31). Resultados: Fueron incluidos 1.416 pacientes con CV < 20 copias/ mL bajo TARV. De ellos, 797 permanecieron con CV< 20 copias/mL durante el seguimiento, 144 presentaron CV entre 20-50 copias/mL, 384 entre 51-200 copias/mL y 91 presentaron FV sin CVBG previa. De los 528 pacientes que tuvieron CVBG, 110 (20,1%) fallaron, riesgo 3,45 veces superior respecto a los que no tuvieron CVBG previa. El riesgo de FV fue 3,27 mayor para aquellos que tuvieron CVBG entre 51-200 copias/mL vs 20-50 copias/mL. Discusión: El estudio permite relacionar la CVBG con el FV posterior, siendo el mayor riesgo CVBG entre 51-200 copias/mL.


Abstract Background: Viral loads (VL) between 20-200 copies/mL are considered low-grade viral loads (LGVL). Its clinical implications and management have not been defined. Aim: To evaluate the impact of LGVL on the risk of subsequent development of virological failure (VF). Methods: Patients ≥ 18 years, with HIV-1 infection who had VL < 20 copies/mL for at least six months and/or in two consecutive samples under antiretroviral therapy (ART) were included, between January 1st, 2009 and December 31, 2019. Follow-up of the VLs was carried out stratifying them in VL < 20 copies/mL, LGVL (20-50 copies/mL and 51-200 copies/mL) and VF. Median follow-up 25 months (IQR 15-31). Results: 1,416 patients were included who reached VL < 20 copies/ml under ART, 797 patients remained with CV < 20 copies/mL during follow-up, 144 patients had VL between 21-50 copies/mL, 384 between 51-200 copies/mL and 91 had VF without previous LGVL. Out of 528 patients who had LGVL, 110 failed, risk 3.45 times higher than those who had no previous LGVL. Risk 3.27 times higher of VF for those who had LGVL between 51-200 copies/mL compared to 20-50 copies/mL. Discussion: The study allows to relate the LGVL with VF. This association was observed more frequently with LGVL between 51-200 copies/mL

ABSTRACT

Resumen: Introducción: En pacientes con Síndrome de Hipoplasia de Ventrículo Izquierdo (SHVI) la primera etapa hacia una fisiología univentricular de Fontan es la operación de Norwood, cuya mortalidad es 10-30%. En estos pacientes la extubación fallida se presenta en un 18% y se ha asociado a aumento de la mortali dad. Objetivo: Describir la frecuencia de extubación fallida y sus factores de riesgo en pacientes con SHVI operados (Norwood). Pacientes y Método: Estudio de casos y controles que incluyó a todos los pacientes con SHVI manejados con cirugía de Norwood en el Hospital Clínico de la Pontificia Universidad Católica (enero-2000 a febrero-2018). Se define como casos a pacientes con falla en la extubación y como controles a los pacientes sin esta complicación. Se registraron variables demográficas, quirúrgicas, y post-quirúrgicas, y se realizó análisis univariado y multivariado (regresión logística) para determinar los factores de riesgo asociados a la falla en la extubación. Resultados: De un total de 107 pacientes, 26 pacientes tuvieron extubación fallida (24,3%). En el análisis univariado los factores asociados a extubación fallida fueron: mayor tiempo de ventilación mecánica postquirúrgico, desarrollar atelectasias, derrame pleural, quilotórax, tener otras comorbilidades respiratorias (apnea y traqueítis), y mayor tiempo de uso de morfina y midazolam. En el análisis multivariado, la presencia de quilotórax, otras comorbilidades respiratorias, y mayor tiempo de uso de midazolam fueron variables asociadas a extubación fallida (p<0,03). La extubación fallida no se asoció a mayor mortalidad. Conclusiones: La presencia de quilotórax, complicaciones respiratorias y uso de mida zolam prolongado deben considerarse para definir el momento de la extubación, con el objetivo de evitar su fracaso.


Abstract: Introduction: Hypoplastic left heart syndrome (HLHS) is the main cause of mortality due to congenital heart disea se. The Norwood surgery is the first procedure of the surgical staging process towards a single ventri cle physiology or Fontan-type operation and has a mortality rate of 10% to 30%. Extubation failure during the postoperative period occurs in up to 18% of these patients and is associated with increased mortality. Objective: To describe extubation failure rates and risk factors in pediatric patients with HLHS who underwent Norwood procedure. Patients and Method: Case-control study that included all the patients with HLHS managed with Norwood surgery at the Hospital Clínico de la Pontificia Universidad Catolica between January 2000 and February 2018. Cases and controls were defined as patients with extubation failure and as patients without this complication, respectively. The following variables were recorded demographic, surgical, and post-surgical ones, and univariate and multivariate analyses (logistic regression) were performed to determine risk factors associated with extubation failure. Results: Out of 107 patients, 26 of them presented extubation failure (24.3%). In the univariate analysis, longer mechanical ventilation time during the postsurgical period, atelectasis, pleural effusion, chylothorax, other respiratory morbidities (i.e. apneas and tracheitis), and longer infusion times of morphine and midazolam, all were associated with a higher extubation failure rate in this population. In the multivariable analysis, chylothorax, other respiratory comorbidities, and longer infusion time of midazolam remained associated with this complication, however, it was not associated with higher mortality. Conclusions: Chylothorax, respiratory comorbidities, and longer use of Midazolam should be addressed before planning airway extubation in order to avoid failure.

ABSTRACT

La resistencia bacteriana a ciertos antibióticos condiciona el éxito del tratamiento erradicador de la infección gástrica por Helicobacter pylori y es motivo de creciente preocupación a nivel mundial. Dada la escasa evidencia publicada en Argentina sobre este tema, nuestro objetivo fue investigar factores asociados a la persistencia de H. pylori post-tratamiento antibiótico. Se determinó la frecuencia de fracaso terapéutico en 81 pacientes con gastritis por H. pylori tratados en nuestro Servicio y sometidos al estudio de urea en aire espirado para confirmar la erradicación de la infección. La edad promedio fue 58±12 y 43.2% eran hombres. La frecuencia de fracaso terapéutico fue 17.3%. De los dos esquemas más utilizados, la frecuencia de fracaso fue mayor con claritromicina + amoxicilina que con levofloxacina + amoxicilina (25% vs. 6.6%, p=0.04). Como factores de riesgo investigamos las siguientes variables: edad, género, síntomas, tabaquismo, consumo de anti-inflamatorios, diabetes, obesidad, tipo y duración de tratamiento. En el análisis univariado, el uso de esquemas con claritromicina y el género masculino se asociaron significativamente a persistencia de la infección [OR 4.2 (1.1-15.6) y 5.2 (1.1-26.4)]. En el análisis multivariado, el uso de esquema con claritromicina permaneció asociado al fracaso terapéutico [OR 5.38 (1.1-29.5)]. Concluimos que la inclusión de claritromicina en el esquema terapéutico para la gastritis por H. pylori se asoció a mayor fracaso terapéutico. Este fracaso es atribuible a alta prevalencia de resistencia de H. pylori a ese antibiótico en la población atendida en nuestro hospital y cuestiona las prácticas habituales de tratamiento en nuestro medio.


Antibiotic resistance may hinder the efficacy of eradication therapy against Helicobacter pylori infection and it has become a major concern worldwide. Due to the relatively scarce evidence published in Argentina on this topic, our aim was to describe factors associated with H. pylori persistence after antibiotic treatment. The therapeutic failure rate was described among 81 patients with H. pylori gastritis treated in our Hospital with a post-treatment urea breath test to determine successful eradication. Mean age was 58 ± 12 and 43.2% were male subjects. H. pylori persistence was observed in 17.3% of subjects. Therapeutic failure was more common among patients receiving clarithromycin + amoxicillin therapy that among those receiving levofloxacin + amoxicillin (25% vs. 6.6%, p = 0.04). The following variables were assessed: age, gender, referral symptoms, smoking, anti-inflammatory use, diabetes, obesity, treatment type and duration. Clarithromycin-based therapy and male gender were associated with infection persistence on univariate analysis [OR 4.2 (1.1-15.6) and 5.2 (1.1-26.4)]. On multivariate analysis, clarithromycin-based was associated with infection persistence [5.38 (1.1-29.5)]. We conclude that clarithromycin-based therapy is significantly associated with treatment failure. This failure may be due to an elevated prevalence of H. pylori resistance to clarithromycin in the population under study and raises the question on the utility of such therapeutic alternative.

ABSTRACT

Abstract Sporotrichosis is a deep mycosis of subacute or chronic evolution, caused by the dimorphic fungus of the genus Sporothrix. The treatment is carried out with antifungal orally or intravenously. Therapeutic success can be affected by several factors, such as altered gastrointestinal physiology by surgery. More and more patients are submitted to bariatric surgeries and the literature for the alterations of the absorption of medications in this context is very scarce. We intend to contribute to a better understanding with this case report of cutaneous-lymphatic sporotrichosis in a patient after bariatric surgery without response to itraconazole treatment, even at high doses.

ABSTRACT

RESUMO Na unidade de terapia intensiva (UTI) pediátrica, a falha de extubação pode aumentar o risco de mortalidade. Este estudo objetivou: (1) verificar a taxa de falha de extubação na UTI pediátrica de um hospital público do município de Bauru (São Paulo, Brasil); (2) identificar a principal causa atribuída à falha de extubação; (3) avaliar se características como a idade e o tempo de ventilação mecânica invasiva (VMI) estão associadas à falha de extubação; (4) avaliar se o tempo de permanência na UTI e hospital é maior entre os pacientes que apresentaram falha de extubação. Foi realizado estudo de coorte retrospectivo com 89 pacientes internados de maio de 2017 até julho de 2018. Os resultados mostraram taxa de falha de extubação correspondente a 16%. A principal causa atribuída à falha de extubação foi o estridor laríngeo, totalizando 57% dos casos. A comparação intergrupos (sucesso vs. falha de extubação) não mostrou diferenças em relação à idade (p=0,294) e ao tempo de VMI (p=0,228). No entanto, observamos que o grupo falha de extubação apresentou maior tempo de UTI (p=0,000) e hospital (p=0,010). Desta forma, concluímos que a taxa de extubação está de acordo com a observada em outros estudos. O estridor laríngeo foi responsável por mais da metade dos casos de falha de extubação. Embora a idade e o tempo de VMI não tenham sido características associadas à falha de extubação, esta contribuiu para o maior período de permanência na UTI e no hospital.


RESUMEN En la unidad de cuidados intensivos (UCI) pediátrica, el fracaso de la extubación puede aumentar el riesgo de mortalidad. Este estudio tuvo el objetivo de: (1) verificar el índice de fracaso de la extubación en la UCI pediátrica de un hospital público en el municipio de Bauru (São Paulo, Brasil); (2) identificar la causa principal atribuida al fracaso de la extubación; (3) evaluar si las características edad y tiempo de ventilación mecánica invasiva (VMI) están asociadas al fracaso de la extubación; (4) evaluar si la duración en la UCI y el hospital es mayor entre los pacientes que experimentaron este fracaso. Se realizó un estudio de cohorte retrospectivo con 89 pacientes hospitalizados desde mayo de 2017 hasta julio de 2018. Los índices del fracaso de la extubación fueron del 16%. El estridor laríngeo fue la causa principal atribuida al fracaso de la extubación, lo que totaliza el 57% de los casos. La comparación intergrupal (éxito versus fracaso de la extubación) no presentó diferencias en relación con la edad (p=0,294) y el tiempo VMI (p=0,228). Se observó que el grupo fracaso de la extubación estuvo más tiempo en la UCI (p=0,000) y el hospital (p=0,010). Se concluye que el índice de extubación está en consonancia con lo observado en otros estudios. El estridor laríngeo fue el responsable de más de la mitad de los casos de fracaso de la extubación. Las características edad y el tiempo de VMI no estuvieron asociadas al fracaso de la extubación, pero esta contribuyó a un período más prolongado en la UCI y en el hospital.


ABSTRACT In the pediatric intensive care unit (ICU), extubation failure may increase mortality risk. This study aimed: (1) to verify the rate of extubation failure in the pediatric ICU of a public hospital located in the city of Bauru (São Paulo, Brazil); (2) to identify the main cause attributed to extubation failure; (3) to evaluate whether age and time of invasive mechanical ventilation (IMV) are characteristics associated to extubation failure; (4) to evaluate whether the length of stay in the ICU/hospital is longer among patients who presented extubation failure. A retrospective study was performed with 89 hospitalized patients from May 2017 to July 2018. Results showed an extubation failure rate corresponding to 16%. The main cause attributed to extubation failure was laryngeal stridor, totaling 57% of the cases. Intergroup comparison (success vs. failure of extubation) showed no differences in relation to age (p=0.294) and IMV time (p=0.228). However, we observed that the extubation failure group had longer ICU (p=0.000) and hospital time (p=0.010). In this way, we conclude that the rate of extubation failure is in agreement with other studies. Laryngeal stridor was responsible for more than half of cases of extubation failure. Although IMV time and age were not associated with the extubation failure, they contributed to a longer stay in the ICU and in the hospital.

ABSTRACT

BACKGROUND: There is limited information regarding the optimal third-line therapy for managing type 2 diabetes mellitus (T2DM) that is inadequately controlled using dual combination therapy. This study assessed the efficacy and safety of pioglitazone or glimepiride when added to metformin plus alogliptin treatment for T2DM.METHODS: This multicenter, randomized, active-controlled trial (ClinicalTrials.gov: NCT02426294) recruited 135 Korean patients with T2DM that was inadequately controlled using metformin plus alogliptin. The patients were then randomized to also receive pioglitazone (15 mg/day) or glimepiride (2 mg/day) for a 26-week period, with dose titration was permitted based on the investigator's judgement.RESULTS: Glycosylated hemoglobin levels exhibited similar significant decreases in both groups during the treatment period (pioglitazone: −0.81%, P<0.001; glimepiride: −1.05%, P<0.001). However, the pioglitazone-treated group exhibited significantly higher high density lipoprotein cholesterol levels (P<0.001) and significantly lower homeostatic model assessment of insulin resistance values (P<0.001). Relative to pioglitazone, adding glimepiride to metformin plus alogliptin markedly increased the risk of hypoglycemia (pioglitazone: 1/69 cases [1.45%], glimepiride: 14/66 cases [21.21%]; P<0.001).CONCLUSION: Among patients with T2DM inadequately controlled using metformin plus alogliptin, the addition of pioglitazone provided comparable glycemic control and various benefits (improvements in lipid profiles, insulin resistance, and hypoglycemia risk) relative to the addition of glimepiride.

ABSTRACT

BACKGROUND: Long-term administration of ethambutol (EMB) for Mycobacterium avium complex lung disease (MAC-LD) sometimes leads to permanent discontinuation of EMB due to various adverse events. This study aimed to investigate treatment outcomes after discontinuation of EMB.METHODS: Among patients diagnosed with MAC-LD between January 2001 and December 2014, 508 patients whose treatment was initiated with standard regimen until May 2018 were enrolled at a tertiary referral center in Korea. Of these 508 patients, 60 (11.8%) discontinued EMB due to various adverse effects. Among these 60 patients, treatment outcomes were analyzed for 44 patients by comparing their outcomes with those of matched subjects who received the standard treatment regimen without EMB discontinuation.RESULTS: The mean age of the 60 patients who discontinued EMB was 64.4 years. Ocular toxicity was the most common cause of discontinuation of EMB (75.0%, 45/60). The mean duration of EMB administration before its discontinuation was 7.0 ± 4.6 months. The treatment failure rate of the 44 patients with EMB discontinuation analyzed for treatment outcome was 29.6%, which was higher than that of the matched patients who received the standard regimen (18.3%), although the difference was not significant (P = 0.095). Of these 44 patients, EMB was substituted with later-generation fluoroquinolone in 23 patients, and the treatment failure rate of these 23 patients was significantly higher than that of the matched patients who received the standard regimen (39.1% vs. 19.3%, P = 0.045).CONCLUSION: These findings suggest that treatment outcomes are unsatisfactory in patients with MAC-LD who discontinue EMB owing to adverse events. Notably, there was a statistically significant high failure rate in patients who were prescribed fluoroquinolone to replace EMB.
