ABSTRACT
Abstract Objective: to investigate the factors associated with extubation failure of patients in the intensive care unit. Method: unpaired, longitudinal, retrospective and quantitative case-control with the participation of 480 patients through clinical parameters for ventilator weaning. Data were analyzed by: Fisher's exact test or the chi-square test; unpaired two-tailed Student's t test; and Mann-Whitney test. Significant P values lower than or equal to 0.05 were admitted. Results: of the patients, 415 (86.5%) were successful and 65 (13.5%) failed. Success group: the most negative fluid balance, APACHE II in 20 (14-25), weak cough in 58 (13.9%). Failure group: the most positive fluid balance, APACHE II in 23 (19-29), weak cough in 31 (47.7%), abundant amount of pulmonary secretions in 47.7%. Conclusion: positive fluid balance and the presence of inefficient cough or inability to clear the airway were predictors of extubation failure.

Objectives: To evaluate the antibiotic resistance pattern, clinical profile and predictors for adverse outcomes in children hospitalized due to staphylococcal infection; and the frequency of nasal and axillary carrier states in these children. Methods: This descriptive study enrolled 100 symptomatic children (aged 1 month - 12 years) in whom S. aureus was isolated from cultures of blood, pus or cerebrospinal fluid. All samples were processed as per the Clinical and Laboratory Standards Institute (CLSI) standards. Antimicrobial susceptibility was tested using disc diffusion method; minimum inhibitory concentration (MIC) for vancomycin was measured using E strips. Predictors for poor recovery were determined by univariate and multivariable logistic regression analysis. Results: Skin and soft tissue infections were the most common (47%) followed by respiratory infections (37%). Methicillin-resistant Staphylococcus aureus (MRSA) was detected in 62%, out of which 63% (39/62) were multi-drug resistant. Carrier state was present in 49% (93% MRSA); 80% were axillary carriers. High MIC (>1 µg/mL) for vancomycin was seen in 65% of patients, and was the only factor associated with poor recovery [aOR (95%CI) 5.3 (1.6,18.5); P=0.008] on multivariable logistic regression analysis. Conclusion: MRSA is the predominant strain in severe staphylococcal infections requiring hospitalization, and majority of them are multidrug resistant. High MIC to vancomycin among S. aureus is an emerging concern.
ABSTRACT
BACKGROUND: In Brazil, there is a scarcity of evidence on migraine burden in patients who have experienced previous preventive treatment failure (PPTF). OBJECTIVE: To evaluate the associations between ≥ 3 PPTF and clinical, psychiatric, and medical history data. METHODS: In a retrospective, cross-sectional study, the medical records of migraine patients who first visited a tertiary specialized clinic were examined. We selected adults of both sexes aged ≥ 18 who attended their first appointment between March and July 2017. Ordinal logistic regression models estimated the associations between number of PPTF (no previous treatment, 1 PPTF, 2, and ≥ 3 PPTF) and chronic migraine, the number of diagnosis exams performed, abortive drugs classes used, and non-pharmacological treatments tried (all categorized as none, 1- 3, and ≥ 4), and severe depression (PHQ-9 ≥ 15) and anxiety (GAD-7 ≥ 15), adjusted for sex, age, and years with disease. RESULTS: Data from 440 patients (72.1 % female) with a mean (SD) age of 37.3 (13.0) years were analyzed. The frequency of no previous treatment was 37.7 % (166/440), while 31.8 % (140/440) showed ≥ 3 PPTF. In patients with ≥ 3 PPTF, 35.7 % (50/140) had episodic, and 64.3 % (90/140) had chronic migraine. Compared to no previous treatment, patients with ≥ 3 PPTF showed higher odds (95 % confidence interval) for chronic migraine [2.10 (1.47, 2.98)], ≥ 4 diagnosis exams [6.59 (3.38, 12.84)], ≥ 4 abortive drug classes [16.03 (9.53, 26.94)], ≥ 4 non-pharmacological treatments [5.91 (3.07,11.35)], and severe depression [1.75 (1.07, 2.88)] and anxiety [1.73 (1.05, 2.85)]. CONCLUSION: Patients first visiting a headache specialist had a high frequency of non-response treatment associated with higher migraine burden in terms of chronification, psychiatric comorbidity, acute medication and non-pharmacological treatment inefficacy, and unnecessary exams.
FUNDAMENTO: No Brasil, há escassez de evidências sobre a carga da enxaqueca em pacientes que apresentaram falha prévia no tratamento preventivo (FTPP). OBJETIVO: Avaliar as associações entre ≥ 3 PPTF e dados clínicos, psiquiátricos e de história médica. MÉTODOS: Em um estudo retrospectivo e transversal, foram examinados os prontuários de pacientes com enxaqueca que visitaram pela primeira vez uma clínica especializada terciária. Foram selecionados adultos de ambos os sexos com idade ≥ 18 anos que compareceram à primeira consulta entre março e julho de 2017. Modelos de regressão logística ordinal estimaram as associações entre número de PPTF (sem tratamento prévio, 1 PPTF, 2 e ≥ 3 PPTF) e enxaqueca crônica, o número de exames de diagnóstico realizados, classes de medicamentos abortivos utilizados e tratamentos não farmacológicos tentados (todos categorizados como nenhum, 1-3 e ≥ 4) e depressão grave (PHQ-9 ≥ 15) e ansiedade (GAD-7 ≥ 15), ajustado por sexo, idade e anos de doença. RESULTADOS: Foram analisados ââdados de 440 pacientes (72,1% mulheres) com idade média (DP) de 37,3 (13,0) anos. A frequência de nenhum tratamento prévio foi de 37,7% (166/440), enquanto 31,8% (140/440) apresentaram ≥ 3 PPTF. Em doentes com ≥ 3 PPTF, 35,7% (50/140) tiveram enxaqueca episódica e 64,3% (90/140) tiveram enxaqueca crónica. Em comparação com nenhum tratamento anterior, pacientes com ≥ 3 PPTF apresentaram chances mais altas (intervalo de confiança de 95%) para enxaqueca crônica [2,10 (1,47, 2,98)], ≥ 4 exames de diagnóstico [6,59 (3,38, 12,84)], ≥ 4 classes de medicamentos abortivos [16,03 (9,53; 26,94)], ≥ 4 tratamentos não farmacológicos [5,91 (3,07;11,35)] e depressão grave [1,75 (1,07; 2,88)] e ansiedade [1,73 (1,05; 2,85)]. CONCLUSÃO: Os pacientes que consultaram pela primeira vez um especialista em dor de cabeça tiveram uma alta frequência de não resposta ao tratamento associada a maior carga de enxaqueca em termos de cronificação, comorbidade psiquiátrica, medicação aguda e ineficácia do tratamento não farmacológico e exames desnecessários.
ABSTRACT
ObjectiveTo analyze the characteristics of HIV-1 subtypes and drug-resistance mutation sites among HIV-infected patients who received high-efficiency antiretroviral therapy but failed. MethodsA total of 130 plasma samples were collected from the patients who received antiviral treatment for 6 months in Taizhou City of Zhejiang Province in 2021 but failed the treatment and the viral load was ≥1 000 copies·mL-1. Nucleic acid in the samples was extracted， and the pol gene was amplified by nested reverse transcription PCR. After next-generation sequencing， online tools were used to compare and analyze the subtypes and drug-resistant mutation sites. ResultsA total of 110 samples were successfully sequenced. The main HIV-1 subtype was CRF01_AE， accounting for 42.72% （47 cases）， followed by CRF07_BC， 35.45% （39 cases）； CRF08_BC， 10.00% （11 cases）； CRF85_BC ， 8.18% （9）； and a small number of B subtype， 1.81% （2 cases） and C subtype， 1.81% （2 cases）. The online tool comparison showed that there were 67 cases with mutations of drug-resistance sites and 61 cases with drug-resistance. The mutation sites were mainly M184V， K103N， K65R and V181C， and the mutation rates were 20.00% （22 cases）， 10.91% （12 cases）， 8.18% （9 cases） and 8.18% （9 cases）， respectively. These mutation sites caused different degrees of resistance to nucleoside reverse transcriptase inhibitors （NRTI）， non- nucleoside reverse transcriptase inhibitors （NNRTI） and protease inhibitors （PI）， including 45 cases of NRTI， 61 cases of NNRTI and 2 cases of PI resistance. ConclusionThe HIV infected people who fail the treatment in Taizhou are mainly with the subtypes CRF01_AE and CRF07_BC. The rate of drug-resistance mutation is at a moderate level， mainly due to the mutation of NRTI and NNRTI drug-resistance sites， and a small number of PI drug-resistance sites. Therefore， the antiviral treatment plan for HIV infected people should be reasonably adjusted， and the detection of drug-resistance mutation sites should be strengthened to avoid the generation of transmissible drug-resistance strains.
ABSTRACT
Objective:To study the effectiveness and safety of intra-amniotic ethacridine injection in pregnancy induction at ≥28 gestational weeks due to fetal demise.Methods:This retrospective study recruited 77 singleton pregnant women who were admitted to Peking University First Hospital at ≥28 gestational weeks, from January 1, 2011 to December 31, 2021, because of fetal demise diagnosed by ultrasound. Four groups were classified according to different methods of induction, including ethacridine success group ( n=63), ethacridine failure group ( n=4), mifepristone plus misoprostol group ( n=5), and spontaneous delivery group ( n=5). Those in the ethacridine success group were further divided into scarred and non-scarred uterus group. The differences in general conditions and delivery outcomes among these women were analyzed using t-test, one-way analysis of variance, Chi-square test, and Mann-Whitney U test or Kruskal-Wallis H test. Results:(1) Among the 67 patients induced by ethacridine, the success rate was 94.0% (63/67). (2) Compared the ethacridine success group with the mifepristone plus misoprostol group or spontaneous delivery group, respectively, there was no significant difference in total labor duration, intrapartum hemorrhage volume, weight of the dead fetus, and the incidence of postpartum hemorrhage, perineal laceration, and intrauterine residue (all P>0.05). No serious complications such as placental abruption, disseminated intravascular coagulation, intrauterine infection, uterine rupture, conversion to cesarean section, or puerperal infection occurred in the three groups. (3) The duration between ethacridine injection and labor onset was shorter in the ethacridine success group than in the mifepristone plus misoprostol group [(28.5±12.0) h vs (54.2±17.6) h, t=－4.45, P<0.001]. (4) Among the 63 cases of ethacridine success group, the outcomes after induction were similar between scarred and non-scarred uterus group (all P>0.05). (5) The median duration between ethacridine injection and labor onset in the ethacridine success group was 26.8 h (2.3-66.0 h), which meant 95% of the patients went into labor within 51.7 h and 100% within 66 h after the injection. Conclusion:Intra-amniotic injection of ethacridine is safe and effective in termination for singleton pregnancy due to fetal demise at the third trimester and the duration from drug administration to labor onset was significantly shorter than that of mifepristone plus misoprostol, without increasing the risk of any complications.
ABSTRACT
ABSTRACT We report the case of a 68-year-old man who presented to our outpatient clinic for routine examination. Fifteen months before, he had undergone combined cataract and idiopathic full-thickness macular hole surgery in his right eye at another institution. In the present evaluation, the best-corrected visual acuity in his right eye was counting fingers. Fundus examination evidenced an idiopathic full-thickness macular hole in that eye, which was confirmed on spectral domain optical coherence tomography. A new surgery was offered, but the patient declined. Twenty-one months after his first consultation with us (36 months after the surgery), spectral domain optical coherence tomography revealed spontaneous closure of the idiopathic full-thickness macular hole, with a gap at the foveal ellipsoid zone. At the final visit, 22 months after the closure of the idiopathic full-thickness macular hole, the patient's best-corrected visual acuity was 20/25, and the gap at the ellipsoid zone had decreased.
RESUMO Este é o relato do caso de um homem de 68 anos que procurou nosso ambulatório para exames de rotina. Quinze meses antes, ele havia se submetido a uma cirurgia conjunta de catarata e buraco macular idiopático de espessura total em seu olho direito, em outra instituição. Durante a consulta em nosso ambulatório, a melhor acuidade visual corrigida no olho direito era de contagem de dedos. O exame do fundo evidenciou um buraco macular idiopático de espessura total naquele olho, o que foi confirmado por uma tomografia de coerência óptica de domínio espectral. Uma nova cirurgia foi oferecida, mas o paciente recusou. Vinte e um meses após sua primeira consulta (36 meses após a cirurgia), a tomografia de coerência óptica de domínio espectral revelou o fechamento espontâneo do buraco macular idiopático de espessura total, com uma lacuna na zona elipsoide foveal. Na última consulta, 22 meses após o fechamento do buraco macular idiopático de espessura total, a melhor acuidade visual corrigida foi de 20/25 e a lacuna na zona elipsoide havia diminuído.
ABSTRACT
ABSTRACT Introduction: Congenital syphilis is a major public health problem, and early diagnosis and treatment are necessary to prevent it. Penicillin G benzathine is the treatment of choice in pregnant women; however, it may fail to prevent fetal infection, as in the present case. Case presentation: Male newborn, son of an HIV negative mother with gestational syphilis (venereal disease research laboratory (VDRL) 1:4 dilution, positive treponemal test) diagnosed at week 21 of gestation and treated with three doses of 2 400 000 IU of penicillin G benzathine. At delivery, the mother presented VDRL 1:1 dilution. The newborn was diagnosed with congenital syphilis due to VDRL 1:4 dilution, positive treponemal test, elevated aspartate aminotransferases, hypos-thenuria, proteinuria, hematuria, and leukocyturia that resolved after treatment with crystalline penicillin for 10 days. The molecular testing in blood showed a high treponemal load. The VDRL test at 3 months was non-reactive. Conclusions: Preventing congenital syphilis with the recommended treatment for gestational syphilis may fail. Moreover, diagnosing this condition in an asymptomatic newborn is difficult. Therefore, clinical and serological tests are recommended to confirm whether maternal treatment was effective in the fetus.
RESUMEN Introducción. La sífilis congénita es un importante problema de salud pública y para prevenirla es necesario diagnosticar y tratar la sífilis gestacional de forma temprana. En el presente caso la gestante recibió el tratamiento de elección (penicilina benzatínica), pero este no previno la infección fetal. Presentación del caso. Recién nacido masculino, hijo de una madre con serología negativa para el virus de la inmunodeficiencia humana y positiva para sífilis gestacional diagnosticada en la semana 21 (prueba VDRL con dilución 1:4 y prueba treponémica rápida positiva) y tratada con tres dosis de 2 400 000 UI de penicilina benzatínica. En el parto, la madre presentó VDRL con dilución 1:1 y el recién nacido fue diagnosticado con sífilis congénita por presentar VDRL con dilución 1:4, prueba treponémica rápida positiva, niveles de aspartato aminotransferasa elevados, hipostenuria, proteinuria, hematuria y leucocituria, condiciones que se resolvieron luego de recibir tratamiento con penicilina cristalina durante 10 días. El estudio molecular en sangre realizado al momento del nacimiento evidenció una alta presencia de Treponema pallidum. La prueba VDRL a los 3 meses fue no reactiva. Conclusiones. Prevenir la sífilis congénita con el tratamiento recomendado para sífilis gestacional puede fallar, además, diagnosticar sífilis congénita en un recién nacido asintomático es difícil, por lo cual se recomienda hacer un seguimiento clínico y serológico para confirmar si el tratamiento materno fue efectivo en el feto.
ABSTRACT
Introducción: Se estima que en 2019 vivían 38 millones de personas con el virus de la inmunodeficiencia humana (VIH), para quienes es fundamental el tratamiento antirretroviral (TAR); sin embargo, no siempre funciona. El fracaso terapéutico del TAR sucede cuando existe una progresión de la enfermedad en parámetros clínicos, virológicos o inmunológicos con un peor pronóstico. Objetivo: Identificar los factores asociados al fracaso terapéutico del TAR en personas viviendo con VIH. Métodos: Se siguieron los lineamientos para revisiones sistemáticas de PRISMA-SCR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews), modificados por Tricco y otros. Los artículos sobre el fracaso terapéutico en población adulta en primera línea de TAR se hallaron en PubMed y la Biblioteca Virtual de Salud. Información, análisis y síntesis: La definición de fracaso terapéutico utilizada en ocho artículos corresponde con los criterios de la OMS; el resto emplea el criterio virológico con distintos puntos de corte. Se describen factores asociados con el fracaso terapéutico con significación estadística, agrupados en factores sociodemográficos (sexo, edad, edad inicio del TAR, compartir estatus de VIH, empleo de drogas inyectables y nivel educativo) y factores clínicos (niveles de linfocitos T CD4+ al inicio del TAR, nivel de adherencia, cambio de régimen, estadio de la OMS al inicio del TAR y coinfección por tuberculosis). Conclusiones: Dos factores fundamentales en el fracaso terapéutico son los sociodemográficos y los clínicos que dependen de la accesibilidad al tratamiento, el sistema de salud y las características intrínsecas de los individuos, incluyendo las conductas en relación con su enfermedad(AU)
Introduction: It is estimated that by 2019 there are 38 million people living with the human immunodeficiency virus (HIV), for whom antiretroviral treatment is essential. Treatment failure occurs when there is a progression of the disease in clinical, virological, or immunological parameters that lead to a change in treatment and a worse prognosis of the disease. The objective of this panoramic review is to answer the following question: What are the factors associated with the therapeutic failure of antiretroviral treatment in people living with HIV? Methods: A panoramic review was carried out following the guidelines for systematic reviews suggested by PRISMA-SCR (Preferred Reporting Items for Systematic Reviews and Meta-Analyzes extension for Scoping Reviews) and modified by Tricco et al. The articles on therapeutic failure in the adult population on the first line of ART were rescued from PubMed and the Virtual Health Library (VHL). The search was limited to a period from 2010 to 2020 and articles whose population was children or pregnant women and articles not available in English or Spanish were excluded. Information, Analysis and Synthesis: The definition of therapeutic failure used corresponds to the WHO criteria in eight articles, while the rest use the virological criterion in variable reference points. Regarding the factors associated with treatment failure, those with statistical significance grouped into sociodemographic factors (sex, age, age of ART onset, shared HIV status, injection drug use, and educational level) and clinical factors (T CD4+ levels are described at the start of ART, level of adherence, change of regimen, WHO stage at the start of ART, and tuberculosis coinfection). Conclusions: Two fundamental factors in therapeutic failure are sociodemographic and clinical, which in turn depend on accessibility to treatment, the health system and intrinsic characteristics of the individuals and the behaviors they adopt in relation to their disease(AU)

ABSTRACT Objectives: The purpose of our study was to assess the association between the winter season and desmopressin treatment failure in South Chinese children with monosymptomatic nocturnal enuresis (MNE). Materials and Methods: A retrospective study was conducted to analyze the clinical data of children with monosymptomatic nocturnal enuresis who have visited our urology clinic from January to December 2019. All patients received desmopressin treatment. Final treatment outcomes were categorized as successful (complete response) or failed (absent and partial response). The relationship between winter season and treatment response to desmopressin was evaluated. Additionally, associated risk factors were investigated with both univariate and multivariate regression analysis. Results: In total, 393 patients diagnosed with MNE were included in the present study. There were no statistically significant differences in pretreatment variables at first visit between patients who visited the clinic in winter and those who did so in other seasons. However, the treatment failure rate of MNE in the winter season was higher than that of other seasons (77.50% vs. 52.74%). Multivariate logistic regression analysis demonstrated that the severity of symptoms and an initial clinic visit in the winter season were significantly related to desmopressin treatment failure in MNE patients. Conclusion: Winter season and severity of symptoms are two risk factors associated with desmopressin treatment failure in MNE patients.

ABSTRACT BACKGROUND: Since its introduction, stapled hemorrhoidopexy has been increasingly indicated in the management of hemorrhoidal disease. AIM: Our primary end point was to evaluate the incidence of recurrent disease requiring another surgical intervention. On a secondary analysis, we also compared pain, complications, and patient's satisfaction after a tailored surgery. METHODS: We retrospectively reviewed 196 patients (103 males and 93 females) with a median age of 47.9 years (range, 17-78) who were undergoing stapled hemorrhoidopexy alone (STG; n=65) or combined surgery (CSG; n=131, stapled hemorrhoidopexy associated with resection). RESULTS: Complications were detected in 11 (5.6%) patients (4.6% for STG vs. 6.1% for CSG; p=0.95). At the same time, symptoms recurrence (13.8% vs. 8.4%; p=034), reoperation rate for complications (3.1% vs. 3.0%; p=1.0), and reoperation rate for recurrence (6.1% vs. 4.6%; p=1.0) were not different among groups. Grade IV patients were more commonly managed with simultaneous stapling and resection (63% vs. 49.5%), but none of them presented symptoms recurrence nor need reoperation due to recurrence. Median pain score during the first week was higher in CSG patients (0.8 vs. 1.7). After a follow-up of 24.9 months, satisfaction scores were similar (8.6; p=0.8). CONCLUSION: Recurrent symptoms were observed in 10% of patients, requiring surgery in approximately half of them. Even though the association of techniques may raise pain scores, a tailored approach based on amplified indication criteria and combined techniques seems to be an effective and safe alternative, with decreased relapse rates in patients suffering from more advanced hemorrhoidal disease. Satisfaction scores after hemorrhoidopexy are high.
RESUMO RACIONAL: Desde sua introdução, a hemorroidopexia por grampeamento tem sido cada vez mais indicada no manuseio da doença hemorroidária. OBJETIVOS: Nosso objetivo primário foi avaliar a incidência de doença recidivada que requeira tratamento cirúrgico. Numa análise secundária, também comparamos dor, complicações e satisfação do paciente após uma operação ajustada a cada caso. MÉTODOS: Foram revistos retrospectivamente 196 pacientes (103 homens e 93 mulheres) com idade média de 47,9 anos (17-78) submetidos a hemorroidopexia mecânica isoladamente (STG; n=65) ou cirurgia combinada (CSG; n=131, hemorroidopexia por grampeamento com ressecção). RESULTADOS: Complicações foram detectadas 11 (5,6%) pacientes (4,6% para STG vs. 6,1% para CSG; p=0,95). Ao mesmo tempo, recidiva de sintomas (13,8% vs. 8,4%; p=034), reoperações por complicações (3,1% vs. 3,0%; p=1,0) ou por recidiva (6,1 vs. 4,6%; p=1,0) não foram diferentes entre os dois grupos. Pacientes com grau IV foram mais comumente manuseados com grampeamento e ressecção simultâneos (63% vs. 49,5%), mas nenhum deles apresentou recidiva ou necessitou reoperação. O escore médio de dor na primeira semana foi maior no grupo CSG (0,8 vs. 1,7). Após seguimento de 24,9 meses, os índices de satisfação foram similares (8,6; p=0,8). CONCLUSÕES: Sintomas de recidiva foram observados em 10%, requerendo cirurgia em aproximadamente metade dos doentes. Embora a associação de técnicas aumente os escores de dor, um procedimento sob medida baseado em critérios ampliados de indicação e técnicas combinadas parece ser uma alternativa efetiva e segura, com menor recidiva em pacientes portadores de doença hemorroidária mais avançada. Os escores de satisfação após hemorroidopexia são altos.
ABSTRACT
Objective:To establish and validate a predictive model for treatment failure of peritoneal dialysis-related peritonitis(PDAP)in elderly patients.Methods:Clinical data of peritoneal dialysis(PD)patients who were followed up from January 1, 2013 to December 31, 2019 at four Grade A tertiary hospitals in Jilin Province were collected.A total of 362 elderly patients with PDAP were eventually included as study subjects.Subjects recruited from 2013 to 2017 were used for model construction and the logistic regression model was used to screen risk factors for treatment failure of PDAP in elderly patients.A nomogarm was constructed to predict treatment failure of secondary PDAP using R language.The receiver operating curve(ROC)and calibration curve were used to evaluate discrimination accuracy of the model.Subjects from 2018 to 2019 were used as the cohort for validation of discrimination accuracy of the model.Results:Of 258 PDAP patients in the modeling cohort, 29 experienced treatment failure, including 15 PDAP-related deaths and 14 cases requiring catheter removal.The multivariate logistic regression model showed that types of pathogens( OR=8.849, 95% CI: 1.656-47.269, P=0.011), long dialysis age( OR=1.023, 95% CI: 1.005-1.042, P=0.013), pre-hospitalization antibiotic treatment( OR=5.123, 95% CI: 1.338-19.610, P=0.017), and dialysate white blood cell count on day 5>100×10 6/L( OR=7.085, 95% CI: 2.162-23.217, P=0.001)were independent risk factors for treatment failure of PDAP in elderly patients.For the nomogarm predictive model, the areas under the ROC curve(AUC)in the modeling cohort and the validation cohort were 0.818(95% CI: 0.735-0.902)and 0.762(95% CI: 0.656-0.889), respectively, and the calibration curves were close to a straight line with a slope of 1. Conclusions:Our nomogram predictive model based on types of pathogens, months of dialysis, pre-hospital admission antibiotic treatment, and dialysate white blood cell count on day 5 has demonstrated satisfactory discrimination accuracy for treatment failure of PDAP in elderly patients.
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.

Objective:To investigate the risk factors associated with failure of trial of labor in primiparous women with preeclampsia (PE) and to establish a risk prediction model.Methods:Primiparae with PE who underwent trial of labor in the Department of Obstetrics of Suzhou Ninth People's Hospital from February 2018 to July 2020 were retrospectively selected as the modeling set, and divided into two groups: the success group and the failure group. Various parameters were compared between the two groups and those data with statistically significant difference were analyzed with multivariate logistic regression analysis. Those factors related to vaginal delivery failure in primiparous women with PE were identified. Based on the results, a risk prediction model was established using R language. Its performance was assessed with receiver operating characteristic (ROC) curve and goodness-of-fit test. This study also retrospectively enrolled primiparae with PE who underwent trial of labor in the same hospital from August 2020 to December 2021 as the validation set. Bootstrap method was used for verification and a calibration chart was created.Results:A total of 312 PE patients were selected as the modeling set with 89 in the failure group and 223 in the success group. Another 146 primiparae with PE were selected as the validation set. Logistic regression analysis showed that older age ( OR=1.609, 95% CI: 1.251-2.483), higher body fat rate in early pregnancy ( OR=1.456, 95% CI: 1.209-2.159) and higher ratio of umbilical artery systolic to diastolic flow velocity within a week before delivery ( OR=1.799, 95% CI: 1.372-2.794) were risk factors for vaginal delivery failure in primiparae with PE, while more maternal education during pregnancy ( OR=0.233, 95% CI: 0.054-0.672) and higher Bishop score ( OR=0.395, 95% CI: 0.258-0.756) were protective factors. A nomogram model to predict the risks of vaginal delivery failure was constructed based on the above five factors. The area under the ROC curve (AUC) of the modeling set was 0.921 (95% CI: 0.847-0.963) with the cut-off value of 0.213, and the corresponding sensitivity and specificity were 0.871 and 0.852, respectively;goodness-of-fit test showed that the observed values matched with those expected ( χ2=7.69, P=0.464); and the calibration curve indicated that the consistency of the prediction model was good. The AUC of the validation set was 0.903 (95% CI: 0.835-0.942) with the sensitivity and specificity of 0.892 and 0.796, respectively; the discrepancy between the observed values and those expected was not significant as indicated by goodness-of-fit test ( χ2=6.82, P=0.512); calibration curve of the validation set showed that the predicted values of the model was consistent with the actual values. Conclusions:The failure of vaginal delivery in primiparae with PE is associated with maternal age, prenatal body fat percentage, ratio of fetal umbilical artery systolic to diastolic flow velocity within a week before delivery, maternal education during pregnancy and Bishop score. The nomogram model based on these five risk factors for prediction of vaginal delivery failure performs well.
ABSTRACT
INTRODUCCIÓN: La neutropenia febril en niños con patología oncohematològica requiere un tratamiento empírico precoz y adecuado. Esta revisión sistemática se realizó para evaluar si piperacilina/tazobactam (PTZ) monoterapia es más efectiva y segura que los comparadores, en niños con episodios de neutropenia febril de causa oncológica. MATERIAL Y MÉTODOS: Se realizó una búsqueda bibliográfica en Embase, MEDLINE utilizando los términos de búsqueda (('febrile neutropenia' OR hemato oncology OR haemato oncology OR 'immunocompromised host' OR 'immunocompromised patient' OR 'chemotherapy-induced febrile neutropenia') AND (piperacillin OR tazobactam OR 'piperacillin plus tazobactam' OR 'piperacillin/tazobactam' OR 'piperacillin-tazobactam' OR tazocin OR 'piperacillin-tazobactam drug combination')). El criterio de valoración de eficacia fue la incidencia de fracaso terapéutico. El punto final de seguridad fue la ausencia de cualquier efecto adverso (EA). RESULTADOS: Se identificaron 1.388 estudios, de los cuales se incluyeron 11 que cumplían los criterios de elegibilidad. Los estudios presentaron notable homogeneidad ( I 2 0%) y no se detectó sesgo de publicación (p 0,36). El riesgo de fracaso terapéutico de PTZ no fue mayor que en los comparadores (RR global: 0,94; IC95% 0,83 a 1,07) como tampoco lo fue, la incidencia de EA. CONCLUSIONES: El riesgo de fracaso terapéutico no fue superior para la PTZ como monoterapia frente a los comparadores
BACKGROUND: Febrile neutropenia in children with onco-hematological diseases is an important cause of morbidity and mortality and requires early and adequate empirical treatment. This systematic review was conducted to evaluate if piperacillin/ tazobactan (PTZ) monotherapy leads to a lower incidence of therapeutic failures than comparators. METHODS: A literature search was carried out in Embase, and MEDLINE databases using the search terms ('febrile neutropenia' OR hemato oncology OR haemato oncology OR 'immunocompromised host' OR 'immunocompromised patient' OR 'chemotherapy-induced febrile neutropenia') AND (piperacillin OR tazobactam OR 'piperacillin plus tazobactam' OR 'piperacillin/tazobactam' OR 'piperacillin-tazobactam' OR tazocin OR 'piperacillin-tazobactam drug combination')), Efficacy endpoint was treatment failure rate. The safety end-point was absence of any adverse effects (AE). RESULTS: Eleven studies were included. No heterogeneity was detected ( I 2 0%). The risk of failure was not superior for piperacillin/tazobactan to comparators (Global RR: 0.94; IC95% 0.83 a 1.07). Rates of adverse events were similar among studies. No publication bias was detected (p 0.36). CONCLUSIONS: This systematic review and meta-analysis showed that treating episodes of febrile neutropenia in oncology pediatric patients, the risk of failure for PTZ was not superior to comparators. Adverse events were similar to the comparators.

Resumen La terapia de la tuberculosis con el esquema primario recomendado por la OMS no logra la curación de todos los casos a nivel mundial, pero en general alcanza un éxito de curación de al menos el 85% de los casos en el año 2018. El mismo año en Chile la eficiencia del tratamiento es solo de 76%, principalmente por la alta proporción de muertes y pérdida de seguimiento durante la terapia. Datos preliminares muestran que la cohorte ingresada en 2019 tuvo un éxito de tratamiento cercano a 74%. En Chile los fracasos de tratamiento son infrecuentes, debido principalmente a la vigilancia nacional de la susceptibilidad a fármacos. Para reducir la letalidad es necesario reforzar las estrategias para el diagnóstico precoz de la tuberculosis, mediante nuevos algoritmos que incorporen la biología molecular y la radiología en casos sospechosos de esta enfermedad, fomentar el adecuado manejo de las comorbilidades, establecer una adecuada red de apoyo social y disponer de centros de hospitalización cuando se requieren. Además, se debe fortalecer la adherencia a la terapia de los pacientes con estrategias de incentivo y facilitación de la asistencia.
Tuberculosis therapy with the primary regimen recommended by the World Health Organization does not cure all cases globally, but it reached success in at least 85% of cases in the year 2018. The same year in Chile, treatment efficiency is achieved in only 76%, mainly due to the high proportion of deaths and loss of follow-up during therapy. Preliminary data show that in the 2019 cohort the success was achieved only in about 74% of new cases. Treatment failures in Chile are rare due to national surveillance of drug susceptibility. To reduce fatality, it is necessary to reinforce the strategies for early diagnosis of tuberculosis through new algorithms. Such strategies should include molecular biology and radiology in suspected TB cases, to promote proper management of comorbidities, establish an adequate social support network and have centers available for prolonged hospitalization when needed. In addition, patient's adherence to therapy should be strengthened with strategies that encourage and facilitate attendance.

O objetivo deste estudo foi relacionar a hipertensão e medicamentos antihipertensivos com o insucesso dos implantes osseointegrados. Foram analisados dados de 602 prontuários de pacientes que receberam tratamento reabilitador com implantes ossseointegrados no período de 2000 a 2017, concluído no mínimo há 6 meses. Foram coletados dados de idade, gênero, presença ou não de hipertensão, uso ou não antihipertensivos, número de implantes instalados e perdidos e tipo de prótese confeccionada. Testes estatísticos de qui-quadrado e teste exato de Fisher foram utilizados para relacionar as variáveis com a perda de implante, com nível de significância de p< 0,05. Foram instalados 1887 implantes com índice de sucesso de 97,51%(47 implantes perdidos em 41 pacientes). Dos 602 pacientes, 71,43 %(432) não apresentavam hipertensão e 28,36% (171) eram hipertensos. A taxa de sucesso dos implantes no grupo de normotensos foi de 93,28% e no grupo de hipertensos foi de 92,99%, não havendo diferença estatística entre eles (P= 0,958). Destes pacientes, as taxas de sucesso foram semelhantes para usuários de medicação (92,5%) e para não usuários (94,1%), não havendo diferença estatística relevante (P= 0,939). A presença da hipertensão, assim como o uso de antihipertensivos não puderam ser associadas ao insucesso dos implantes osseointegrados(AU)
The aim of this study was to relate hypertension and antihypertensive drugs to the failure of osseointegrated implants. Were analyzed 602 medical records of patients who received rehabilitation treatment with osseointegrated implants between 2000 and 2017, completed at least 6 months ago. Age, gender, presence or absence of hypertension, use or not antihypertensive drugs, number of installed and lost implants and type of prosthesis made were collected. Statistical chi-square tests and Fisher's exact test were used to relate the variables with implant loss, with a significance level of p < 0.05. 1,887 implants were installed with a success rate of 97.51% (47 implants lost in 41 patients). Of the 602 patients, 71.43% (432) did not have hypertension and 28.36% (171) were hypertensive. The success rate of implants in the normotensive group was 93.28% and in the hypertensive group it was 92.99%, with no statistical difference between them (P = 0.958). Of these patients, the success rates were similar for medication users (92.5%) and for non-users (94.1%), with no statistically significant difference (P = 0.939). The presence of hypertension, as well as the use of antihypertensives, could not be associated with the failure of osseointegrated implants(AU)

ABSTRACT Purpose: although locking plates have led to important changes in fracture management, becoming important tools in the orthopedic surgeon's arsenal, the benefits of locking plates for traumatic diastasis of the pubic symphysis have not been established. This study was conducted to assess the quality of life in its different domains among patients with traumatic diastasis of the pubic symphysis managed either with locking or nonlocking plate. Methods: a prospective cohort study was undertaken at 3 level 1 trauma centres in Brazil. Patients presenting traumatic diastasis of the pubic symphysis treated with plate fixation with a minimum follow-up of 12 months were eligible for inclusion. Through a Pfannenstiel approach, the pubic symphysis was reduced and fixed with a superiorly positioned 4.5mm four to six hole reconstruction locked plate or 3.5mm four to six hole reconstruction nonlocked plate. Posterior injury was managed during the same procedure. Outcome measures were adequate healing of the pelvic injuries, return to pre-injury level on daily activities, and quality of life at the last follow-up visit. Complications and modes of failure were summarized and reviewed. Bivariate linear regression was used to assess individual factors affecting patients' health-related quality of life. A p value of <5% was considered significant. Results: a total of 31 adult patients (29 males and 2 females) were eligible for the study. Thirteen patients were managed with a reconstruction locked plate and 18 patients with a nonlocked reconstruction plate. Average postoperative follow-up time was 24 months. Adequate healing of the pelvic injuries was achieved in 61.5% of patients treated with locking plates and 94.4% of patients treated with nonlocking plates (p=0.003). Radiographic failure of fixation with minor complications occurred in 46.1% of patients after locked plating versus 11.1% of patients in the nonlocking plate group (p=0.0003). In bivariate analysis, abnormal gait (p=0.007) was associated with a reduced long-term quality of life as measured with the EQ-5D-3L. Conclusion: internal fixation of traumatic diastasis of the pubic symphysis with locking plates has no clinical advantage when compared to nonlocked plating. Mechanical failure and inadequate healing are significantly increased after locked plating of the pubic symphysis. Therefore, we do not recommend routine use of locking plates for managing patients presenting traumatic diastasis of the pubic symphysis. Level of evidence: II (prospective, cohort study).
RESUMO Justificativa e Objetivo: embora as placas bloqueadas tenham levado a mudanças importantes no tratamento de fraturas, tornando-se ferramentas importantes no arsenal do cirurgião ortopédico, os benefícios para a fixação da lesão da sínfise púbica não foram adequadamente estabelecidos. Este estudo foi realizado para avaliar a qualidade de vida em diferentes domínios de pacientes com disjunção traumática da sínfise púbica tratados com placas bloqueadas e não bloqueadas. Métodos: trata-se de estudo de coorte prospectivo, realizado em três centros de trauma nível 1, no Brasil. Foram elegíveis para inclusão no estudo pacientes com disjunção traumática da sínfise púbica tratados com redução aberta e fixação interna com placa, com seguimento mínimo de 12 meses. Por meio de abordagem de Pfannenstiel, a sínfise púbica foi reduzida e fixada com uma placa bloqueada de reconstrução de 4,5mm de quatro a seis orifícios posicionada superiormente ou com uma placa não bloqueada de reconstrução de 3,5mm de quatro a seis orifícios. A lesão pélvica posterior foi tratada durante o mesmo procedimento. Os desfechos analisados na última visita de acompanhamento foram cicatrização da lesão pélvica, retorno às atividades diárias para nível pré-lesional e qualidade de vida. Complicações e modos de falha foram observados e descritos. Foi utilizada regressão linear bivariada na avaliação dos fatores individuais que afetaram a qualidade de vida relacionada à saúde dos pacientes, com valor p <5% considerado significativo. Resultados: foram incluídos no estudo 31 pacientes adultos (29 homens e 2 mulheres). Treze pacientes foram tratados com placa de reconstrução bloqueada e 18 com placa de reconstrução não bloqueada. O tempo médio de seguimento pós-operatório foi de 24 meses. A cicatrização adequada da lesão do anel pélvico foi alcançada em 61,5% dos pacientes tratados com placas bloqueadas e em 94,4% dos pacientes tratados com placas não bloqueadas (p=0,003). Falha radiográfica de fixação com complicações menores ocorreu em 46,1% dos pacientes tratados com placa bloqueada contra 11,1% dos pacientes no grupo de placas não bloqueadas (p=0,0003). Na análise bivariada, marcha anormal (p=0,007) foi associada à redução da qualidade de vida em longo prazo, medida com o EQ-5D-3L, embora não tenha sido observada relação direta destas com os implantes utilizados. Conclusão: a fixação interna da disjunção traumática da sínfise púbica com placas bloqueadas não apresenta vantagem clínica quando comparada com placas não bloqueadas. Falha mecânica e cicatrização inadequada aumentam significativamente após o uso de placas bloqueadas na sínfise púbica. Portanto, não recomendamos o uso rotineiro de placas bloqueadas para o tratamento de pacientes com disjunção traumática da sínfise púbica. Nível de evidência: II (estudo de coorte prospectivo).

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
