Risk Factors For Unfavorable Outcome Research Articles

540: NEUROLOGIC OUTCOMES IN HOSPITALIZED CHILDREN WITH ACUTE SARS-COV-2 OR MIS-C

Introduction: We aimed to describe neurologic outcomes in hospitalized children diagnosed with acute SARS-CoV-2 infection or Multisystem Inflammatory Syndrome in Children (MIS-C). Methods: Multinational (n=50 centers), cross-sectional study of neurologic manifestations in children < 18 y old hospitalized with a positive SARS-CoV-2 test or clinical diagnosis of a SARS-CoV-2-related condition between January 2020-July 2021. Multivariable logistic regression to identify risk factors for unfavorable outcome at hospital discharge (Pediatric Cerebral Performance Category Score 3-6) was performed. Severe neurologic manifestation included those with univariate logistic regression significant to p< 0.05 for unfavorable outcome: dysautonomia, stroke, encephalopathy, cardiac arrest, meningitis/encephalitis, coma, seizures, weakness, and delirium. Results: Of 3,556 children (46% female), 3333 (94%) had acute SARS-CoV-2 and 223 (6%) had MIS-C. Unfavorable outcome occurred in 368 (11%) children and 39 (1.1%) died. Children with unfavorable outcome were older (median 9 interquartile range [4-14] vs. 8 [1-14] y, p< 0.001), and more likely to have neurologic comorbidity (72% vs. 10%, p< 0.001), worse Glasgow coma scale score (GCS) group (19% with combined GCS 9-15 vs. 1.7% with GCS< 9, p< 0.001), any neurologic manifestation (52% vs. 37%, p< 0.001), and severe neurologic manifestation (48% vs. 20%, p< 0.001) compared to children with favorable outcome. In multivariate logistic regression, older age (odds ratio 1.1 95% confidence interval [1.0, 1.1], total pre-existing conditions (2.1 [1.8, 2.5]), severe neurologic manifestation (3.4 [2.0, 6.0], and worse GCS group (4.0 [2.6, 5.9]) were associated with unfavorable outcome. Conclusions: Children with severe neurologic manifestation, pre-existing conditions, and children of older age hospitalized with acute SARS-CoV-2 infection or MIS-C have worse hospital discharge outcomes. Follow-up of these children is necessary to identify and manage neurologic and functional impairment.

Factors influencing drug susceptible tuberculosis outcomes in Eastern Europe

Objective — to conduct a retrospective analysis of factors that affect the results of treatment of patients with tuberculosis.&#x0D; Materials and methods. A retrospective multi-center study was conducted on adult (&gt; 18 years) patients diagnosed with drug-sensitive susceptible TB of any form and initiated treatment between 1st of January 2019 — 31st of December 2019. The Bucharest Marius Nasta Institute, the Iasi Lung Hospital in Romania, and Chernivtsi TB Centre in Ukraine participated in this study. The study was approved by the ethics committee of each centre (Iassi: 5483/2021, Bucharest: 10592/2019, Chernivtsi: 234/2021,). The need for written informed consent was waived due to the retrospective nature of this study.&#x0D; Results and discussion. It is important to study the factors that influence the course and effectiveness of TB treatment, as they can be useful for the development of new methods of diagnosis and treatment. Our retrospective study identified such factors in an Eastern European population. The risk of adverse consequences increases for the elderly, people without a permanent place of residence, patients with already diagnosed chronic kidney disease, the presence of cavities on a chest X-ray, rapid relapse of TB, under­weight or obesity.These factors may help tailor care to specific populations and may lead to improved TB scoring systems to identify patients at risk of treatment failure.&#x0D; Conclusions. Our study presented common risk factors for unfavourable outcomes with previous research, including age, sex, nutritional status, lifestyle, comorbidities, TB-related parameters, but introduced a new, paraclinical parameter, and highlighted differences for East Europe.

A novel nomogram model for clinical outcomes of severe subarachnoid hemorrhage patients.

Systemic responses, especially inflammatory responses, after aneurysmal subarachnoid hemorrhage (SAH) are closely related to clinical outcomes. Our study aimed to explore the correlation between the systemic responses in the acute stage and the mid-term outcomes of severe SAH patients (Hunt-Hess grade III-V). Severe SAH patients admitted to Jinling Hospital from January 2015 to December 2019 were retrospectively analyzed in the study. The univariate and multivariate logistic regression analyses were used to explore the risk factors of 6-month clinical outcomes in severe SAH patients. A predictive model was established based on those risk factors and was visualized by a nomogram. Then, the predictive nomogram model was validated in another severe SAH patient cohort from January 2020 to January 2022. A total of 194 patients were enrolled in this study. 123 (63.4%, 123 of 194) patients achieved good clinical outcomes at the 6-month follow-up. Univariate and multivariate logistic regression analysis revealed that age, Hunt-Hess grade, neutrophil-to-lymphocyte ratio (NLR), and complications not related to operations were independent risk factors for unfavorable outcomes at 6-month follow-up. The areas under the curve (AUC) analysis showed that the predictive model based on the above four variables was significantly better than the Hunt-Hess grade (0.812 vs. 0.685, P = 0.013). In the validation cohort with 44 severe SAH patients from three different clinical centers, the AUC of the prognostic nomogram model was 0.893. The predictive nomogram model could be a reliable predictive tool for the outcome of severe SAH patients. Systemic inflammatory responses after SAH and complications not related to operations, especially hydrocephalus, delayed cerebral ischemia, and pneumonia, might be the important risk factors that lead to poor outcomes in severe SAH patients.

Comparative analysis of outcome predictors in patients with postoperative peritonitis depending on the method of surgical treatment – relaparotomy on demand vs vacuum-assisted laparostomy

Background: Secondary postoperative diffuse peritonitis (SPDP) is one of the most severe complications of elective and emergency surgical interventions associated with a high mortality rate. To date, no optimal tactics of surgical treatment of SPDP has been developed.Objective: The analysis of independent predictors of outcome depending on the method of surgical treatment – relaparotomy ondemand (RD) or vacuum-assisted laparostomy (VAL).Material and methods: The study included 141 adult patients, male and female in the period from January 2014 to December 2020: group I (n = 63) – patients who received VAL method; group II (n = 78) – RD method. The method of multivariate logistic regression analysis was used to calculate the independent effects of potential predictor variables on the treatment outcome.Results: The following independent predictors of treatment outcome in the RD group were identified: age, duration of hospital stay, number of relaparotomies, APACHE II score, Björck classification grade 1C at the 1st sanitation, bacteremia, Clavien–Dindo complications class 3a and 4a. For the VAL group: conversion of surgical tactics and bacteremia.Conclusion: In patients with SPDP in the presence of risk factors for unfavorable outcomes, the use of VAL with staged sanitation of the abdominal cavity is indicated.

Comparison of Parent Artery Occlusion and Stent-Assisted Treatments in Ruptured Vertebral Artery Dissecting Aneurysms.

To assess clinical outcomes of ruptured vertebral artery dissecting aneurysms, focusing on comparing parent artery occlusion (PAO) with stent-assisted treatments, and to identify risk factors for unfavorable outcomes and postprocedural complications. This retrospective review included 36 ruptured vertebral artery dissecting aneurysms treated between February 2009 and April 2020. Treatment modalities included PAO without stent and stent-assisted treatments. Stent-assisted treatments included PAO with posterior inferior cerebellar artery (PICA) stenting and stent-assisted coiling. Univariate and multivariate analyses were conducted to evaluate risk factors for unfavorable outcomes and postprocedural complications. Patients were treated with PAO only (24, 66.7%), PAO with PICA stenting (4, 11.1%), and PAO with stent-assisted coiling (8, 22.2%). There were only fusiform aneurysms with PICA involvement in the PAO with PICA stenting group. In the stent-assisted coiling group, 4 aneurysms incorporated PICA, and 4 aneurysms involved dominant vertebral artery. Old age (odds ratio [OR]= 1.25, 95% confidence interval [CI]= 1.01-1.56, P= 0.044) and poor Hunt-Hess grade (OR= 537.99, 95% CI= 6.73-42994.1, P= 0.005) were significantly associated with unfavorable clinical outcomes after a mean follow-up of 37.5 ± 32.8 months. Fusiform dilatation shape (OR= 15.97, 95% CI= 1.52-167.38, P= 0.021) and PICA involvement (OR= 13.71, 95% CI= 1.29-145.89, P= 0.030) were independent risk factors for ischemic complications. Unfavorable clinical outcomes were significantly related to old age and poor Hunt-Hess grade. There were no significant differences between treatment groups in clinical outcomes or ischemic complications. Stent-assisted treatments might be effective and safe methods for ruptured vertebral artery dissecting aneurysms.

Risk factors for unfavorable outcome at discharge of newborns with hypoxic-ischemic encephalopathy in the era of hypothermia.

To re-visit short-term outcomes and associated risk factors of newborns with hypoxic-ischemic encephalopathy (HIE) in an era where hypothermia treatment (HT) is widespread. This is a prospective population-based cohort in French neonatal intensive care units (NICU). Neonates born at or after 34 weeks of gestational age with HIE were included; main outcomes were in-hospital death and discharge with abnormal or normal MRI. Associations of early perinatal risk factors, present at birth or at admission to NICU, with these outcomes were studied. A total of 794 newborns were included and HT was administered to 670 (84.4%); 18.3% died and 28.5% and 53.2% survived with abnormal and normal MRI, respectively. Severe neurological status, Apgar score at 5 mn ≤5, lactate at birth ≥11 mMoles/l, and glycemia ≥100 mg/dL at admission were associated with an increased risk of death (relative risk ratios (aRRR) (95% CI) 19.93 (10.00-39.70), 2.89 (1.22-1.62), 3.06 (1.60-5.83), and 2.55 (1.38-4.71), respectively). Neurological status only was associated with survival with abnormal MRI (aRRR (95% CI) 1.76 (1.15-2.68)). Despite high use of HT in this cohort, 46.8% died or presented brain lesions. Early neurological and biological examinations were associated with unfavorable outcomes and these criteria could be used to target children who warrant further neuroprotective treatment. Clinical trial registry, NCT02676063, ClinicalTrials.gov. In this population-based cohort of newborns with HIE where 84% received hypothermia, 46.8% still had an unfavorable evolution (death or survival with abnormal MRI). Risk factors for death were high lactate, low Apgar score, severe early neurological examination, and high glycaemia. While studies have established risk factors for HIE, few have focused on early perinatal factors associated with short-term prognosis. This French population-based cohort updates knowledge about early risk factors for adverse outcomes in the era of widespread cooling. In the future, criteria associated with an unfavorable evolution could be used to target children who would benefit from another neuroprotective strategy with hypothermia.

Postoperative neutrophil-lymphocyte ratio predicts unfavorable outcome of acute ischemic stroke patients who achieve complete reperfusion after thrombectomy.

PurposeOnly approximately half of anterior circulation large vessel occlusion (LVO) patients receiving endovascular treatment (EVT) have a favorable outcome. The aim of this study was to explore the association of dynamic inflammatory markers (i.e., neutrophil to lymphocyte ratios, NLR, measured at different times after EVT) as well as other potential influencing factors with unfavorable outcome among acute ischemic stroke (AIS) patients who achieved complete reperfusion after EVT.MethodsPatients treated with EVT for LVO between January 2019 to December 2021 were prospectively enrolled. Complete reperfusion was defined as modified thrombolysis in cerebral infarction (mTICI) grade 3. A modified Rankin scale at 90 days (mRS90) of 3–6 was defined as unfavorable outcome (i.e., futile reperfusion). A logistic regression analysis was performed with unfavorable outcome as a dependent variable. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) were then used to determine the diagnostic values of NLR and other relevant factors.Results170 patients with complete reperfusion (mTICI 3) were included in this study. Unfavorable outcome was observed in 70 (41.2%). Higher NLR within 24h (p=0.017) and at 3-7d (p=0.008) after EVT were an independent risk factors for unfavorable outcome at 3 months. In addition, older age, higher NIHSS scores, poor collaterals, and general anesthesia were independent predictors of unfavorable outcomes. When accounting for NLR, the diagnostic efficiency improved compared to conventional characteristics.ConclusionOur findings suggest that advanced age, increased stroke severity, poor collaterals, general anesthesia, and NLR are independent predictors for an unfavorable clinical outcome following complete reperfusion after EVT. Neuroinflammation may merit particular attention in future studies.

Temporal Patterns in Brain Tissue and Systemic Oxygenation Associated with Mortality After Severe Traumatic Brain Injury in Children.

Brain tissue hypoxia is an independent risk factor for unfavorable outcomes in traumatic brain injury (TBI); however, systemic hyperoxemia encountered in the prevention and/or response to brain tissue hypoxia may also impact risk of mortality. We aimed to identify temporal patterns of partial pressure of oxygen in brain tissue (PbtO2), partial pressure of arterial oxygen (PaO2), and PbtO2/PaO2 ratio associated with mortality in children with severe TBI. Data were extracted from the electronic medical record of a quaternary care children's hospital with a level I trauma center for patients ≤ 18years old with severe TBI and the presence of PbtO2 and/or intracranial pressure monitors. Temporal analyses were performed for the first 5days of hospitalization by using locally estimated scatterplot smoothing for less than 1,000 observations and generalized additive models with integrated smoothness estimation for more than 1,000 observations. A total of 138 intracranial pressure-monitored patients with TBI (median 5.0 [1.9-12.8] years; 65% boys; admission Glasgow Coma Scale score 4 [3-7]; mortality 18%), 71 with PbtO2 monitors and 67 without PbtO2 monitors were included. Distinct patterns in PbtO2, PaO2, and PbtO2/PaO2 were evident between survivors and nonsurvivors over the first 5days of hospitalization. Time-series analyses showed lower PbtO2 values on day 1 and days 3-5 and lower PbtO2/PaO2 ratios on days 1, 2, and 5 among patients who died. Analysis of receiver operating characteristics curves using Youden's index identified a PbtO2 of 30mm Hg and a PbtO2/PaO2 ratio of 0.12 as the cut points for discriminating between survivors and nonsurvivors. Univariate logistic regression identified PbtO2 < 30mm Hg, hyperoxemia (PaO2 ≥ 300mm Hg), and PbtO2/PaO2 ratio < 0.12 to be independently associated with mortality. Lower PbtO2, higher PaO2, and lower PbtO2/PaO2 ratio, consistent with impaired oxygen diffusion into brain tissue, were associated with mortality in this cohort of children with severe TBI. These results corroborate our prior work that suggests targeting a higher PbtO2 threshold than recommended in current guidelines and highlight the potential use of the PbtO2/PaO2 ratio in the management of severe pediatric TBI.

Obesity is associated with a higher Torque Teno viral load compared to leanness.

IntroductionObesity affects a rising proportion of the population and is an important risk factor for unfavorable outcomes in viral disease including severe acute respiratory syndrome coronavirus 2- associated diseases. Torque Teno virus (TTV) is a ubiquitous and apathogenic virus which reflects the immune function of its host. The aim of this study was to investigate the association between obesity and TTV load - an indirect marker of compromised viral immune response.MethodsTTV was quantified by TTV R-GENE® PCR in a total of 89 participants of which 30 were lean (BMI <25 kg/m2) and 59 were obese (BMI >30 kg/m2). For 38 subjects, follow-up was available after bariatric surgery.ResultsTTV load was higher in individuals with obesity (median 2.39, IQR: 1.69–3.33 vs. 1.88, IQR 1.08–2.43 log10 copies/mL; p = 0.027). Multivariable linear modeling revealed an independent association between TTV load and obesity. TTV was positively correlated with waist-to-hip ratio and inversely with 25OH vitamin D levels. Interleukin 6 and fasting insulin resistance were confounders of the association between TTV and obesity, while age was an effect modifier. TTV load increased by 87% (95% CI 2–243%) in the year following bariatric surgery.DiscussionA higher TTV load in obese individuals may reflect compromised immune function and thus might serve for risk stratification of unfavorable outcomes during infectious disease, including coronavirus disease 2019, in this population. Our data warrant further analysis of TTV-based risk assessment in obese individuals in the context of infectious disease-associated outcomes.

Sex Differences in TB Clinical Presentation, Drug Exposure, and Treatment Outcomes in India

The role of sex differences in clinical presentation, TB drug pharmacokinetic variables, and treatment outcomes is unclear. What is the effect of sex on TB disease severity, drug exposure, and treatment outcome? This study was a prospective cohort study conducted in India. It assessed TB disease severity; risk of unfavorable treatment outcomes (failure, recurrence, and death) according to sex; and risk factors for unfavorable outcomes stratified according to sex. Effects of sex on the pharmacokinetic variables (maximum concentration and area under the curve) of rifampicin, isoniazid, and pyrazinamide were estimated by using noncompartmental analyses. Of 1,541 people with microbiologically confirmed TB, 567 (37%) were women. Women had a lower risk of high mycobacterial burden (smear grade≥ 2 and/or time to detection< 7days) with an adjusted OR of 0.70 (95%CI, 0.56-0.87). Among the 744 participants who were followed up prospectively, 261 (35%) were women. Women had a lower risk of unfavorable treatment outcomes (adjusted incidence risk ratio, 0.60; 95%CI, 0.43-0.85), mostly because recurrence was lower (adjusted incidence risk ratio, 0.45; 95%CI, 0.23-0.86). Isoniazid (but not rifampicin and pyrazinamide) maximum concentration and area under the curve were significantly higher among women (P< .01) than men. Among women, unfavorable outcomes were more likely among those with cavitary disease, but among men, increased risk of unfavorable outcomes was associated with alcohol use, higher BMI, and lower glycated hemoglobin level. Women present with lower mycobacterial burden, achieve higher TB drug exposure, and are less likely to have unfavorable treatment outcomes than men. Strategies to improve TB treatment success should take into account sex differences in risk factors for unfavorable outcomes.

Factors Predictive of Varicella Zoster Virus Encephalitis/Meningitis: A Single-Center, Retrospective Study.

BackgroundThe outcomes of varicella zoster virus (VZV) encephalitis/meningitis vary from complete recovery to severe complications. This study aimed to investigate the predictive factors of encephalitis and meningitis caused by VZV reactivation.Material/MethodsVZV encephalitis/meningitis patients (n=39) who were treated between January 2019 and December 2021 were included. Patients were followed up for 3 months after discharge and divided into a favorable outcome group (FO, n=18; 46.2%) and an unfavorable outcome group (UO, n=21; 53.8%) according to whether it affects quality of life. The clinical data were retrospectively analyzed and compared between groups.ResultsAs compared to the FO group, patients in the UO group were more likely to have higher body temperature (>38°C) at admission, longer interval from onset of CNS symptoms to initial of antiviral therapy, higher white blood cells (WBC) and adenosine deaminase (ADA) in the cerebrospinal fluid (CSF) and higher CRP in the blood (P<0.05 or P<0.01). Univariate logistic regression analysis showed CSF ADA (OR=1.279, 95% CI: 0.996~1.642) and interval from onset of CNS symptoms to initial of antiviral therapy (OR=1.299, 95% CI: 1.011~1.669) were independent risk factors for unfavorable outcomes (P<0.05). The sensitivity and specificity of combined CSF ADA and time interval from onset of CNS symptoms to initial of antiviral therapy were 78.8% and 95.2%, respectively, in predicting outcomes.ConclusionsHigher CSF ADA and longer interval from onset of CNS symptoms to initial of antiviral therapy predict an unfavorable outcome, and the combination of both factors can achieve better performance.

Clinical outcomes of laser vaporization for vaginal intraepithelial neoplasia – A 20-year retrospective review

ObjectivesThe purpose of our study is to evaluate clinical outcomes of CO2 laser vaporization in patients with high-grade vaginal intraepithelial neoplasia (VAIN), and analyze potential risk factors for unfavourable outcome. Study designA retrospective cohort study was carried out on all patients with high-grade VAIN treated by laser vaporization from Jan 2001 to Dec 2020 in a gynae-oncology training centre in Hong Kong. ResultsA total of 116 women underwent laser therapy for high-grade VAIN during the study period and the median follow-up time was 49.5 months. Disease regression was achieved in 75% of patients after first laser treatment. However, 23% of them had disease recurrence after initial regression. Regression rate declined significantly at subsequent laser treatment for disease persistence or recurrence, from 75% after the first laser, to 52.9% after the second laser and 26.5% after the third or more laser (p < 0.001). Eleven patients (9.4%) had disease progression to cancer during subsequent follow-ups. VAIN 3 was the only independent risk factor for unfavourable outcome after multivariable logistic regression (OR = 2.86, 95% CI 1.16–7.06, p = 0.023). ConclusionCO2 laser vaporization is a safe and effective treatment modality for high-grade VAIN, but with high recurrence rate. Patients should be carefully counselled about treatment failure, recurrence risk, and the need for long-term surveillance for any progression to cancer. Alternative treatment modalities should be considered in patients who failed to regress after two episodes of laser treatment.

Risk factors for unfavourable outcomes after shunt surgery in patients with idiopathic normal-pressure hydrocephalus

A number of vascular risk factors (VRFs) have been reported to be associated with idiopathic normal-pressure hydrocephalus (iNPH), but it remains unclear whether these VRFs are related to patient outcomes after shunt surgery. Therefore, we investigated the risk factors for unfavourable outcomes after shunt surgery in iNPH patients using two samples from Tohoku University Hospital and from a multicentre prospective trial of lumboperitoneal (LP) shunt surgery for patients with iNPH (SINPHONI-2). We enrolled 158 iNPH patients. We compared the prevalence of VRFs and clinical measures between patients with favourable and unfavourable outcomes and identified predictors of unfavourable outcomes using multivariate logistic regression analyses. The presence of hypertension, longer disease duration, more severe urinary dysfunction, and a lower Evans’ index were predictors of unfavourable outcomes after shunt surgery. In addition, hypertension and longer disease duration were also predictors in patients with independent walking, and a lower Evans’ index was the only predictor in patients who needed assistance to walk or could not walk. Our findings indicate that hypertension is the only VRF related to unfavourable outcomes after shunt surgery in iNPH patients. Larger-scale studies are needed to elucidate the reason why hypertension can affect the irreversibility of symptoms after shunt placement.

In-hospital complication-related risk factors for discharge and 90-day outcomes in patients with aneurysmal subarachnoid hemorrhage after surgical clipping and endovascular coiling: a propensity score-matched analysis.

More than 10 years have passed since the two best-known clinical trials of ruptured aneurysms (International Subarachnoid Aneurysm Trial [ISAT] and Barrow Ruptured Aneurysm Trial [BRAT]) indicated that endovascular coiling (EC) was superior to surgical clipping (SC). However, in recent years, the development of surgical techniques has greatly improved; thus, it is necessary to reanalyze the impact of the differences in treatment modalities on the prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH). The authors retrospectively reviewed all aSAH patients admitted to their institution between January 2015 and December 2020. The functional outcomes at discharge and 90 days after discharge were assessed using the modified Rankin Scale (mRS). In-hospital complications, hospital charges, and risk factors derived from multivariate logistic regression were analyzed in the SC and EC groups after 1:1 propensity score matching (PSM). The area under the receiver operating characteristic curve was used to calculate each independent predictor's prediction ability between treatment groups. A total of 844 aSAH patients were included. After PSM to control for sex, aneurysm location, Hunt and Hess grade, World Federation of Neurosurgical Societies (WFNS) grade, modified Fisher Scale grade, and current smoking and alcohol abuse status, 329 patients who underwent SC were compared with 329 patients who underwent EC. Patients who underwent SC had higher incidences of unfavorable discharge and 90-day outcomes (46.5% vs 33.1%, p < 0.001; and 19.6% vs 13.8%, p = 0.046, respectively), delayed cerebral ischemia (DCI) (31.3% vs 20.1%, p = 0.001), intracranial infection (20.1% vs 1.2%, p < 0.001), anemia (42.2% vs 17.6%, p < 0.001), hypoproteinemia (46.2% vs 21.6%, p < 0.001), and pneumonia (33.4% vs 24.9%, p = 0.016); but a lower incidence of urinary tract infection (1.2% vs 5.2%, p = 0.004) and lower median hospital charges ($12,285 [IQR $10,399-$15,569] vs $23,656 [IQR $18,816-$30,025], p < 0.001). A positive correlation between the number of in-hospital complications and total hospital charges was indicated in the SC (r = 0.498, p < 0.001) and EC (r = 0.411, p < 0.001) groups. The occurrence of pneumonia and DCI, WFNS grade IV or V, and age were common independent risk factors for unfavorable outcomes at discharge and 90 days after discharge in both treatment modalities. EC shows advantages in discharge and 90-day outcomes, in-hospital complications, and the number of risk factors but increases the economic cost on patients during their hospital stay. Severe in-hospital complications such as pneumonia and DCI may have a long-lasting impact on the prognosis of patients.

Nutritional status in patients with hepatocellular carcinoma: Potential relevance for clinical outcome

BackgroundImpaired nutritional status is a risk factor for unfavorable outcome in cirrhosis. MethodsIn this prospective cohort study in hepatocellular carcinoma patients referred for tumor-specific therapy, nutritional status was assessed before and 3 months post-treatment using 4 complementary tools: hand-grip strength (HGS), Liver Frailty Index (LFI), Patient-Generated Subjective Global Assessment (PG-SGA) and skeletal muscle index (L3-SMI). Uni- and multivariable analyses were performed using Kaplan Meier curves and Cox's regression analyses with correction for Barcelona Clinic Liver Cancer (BCLC) stage, alpha-fetoprotein and age. Results56 patients were evaluated at baseline and 38 patients 3 months post-treatment. Baseline BCLC stage was 0 in 14%, A in 27%, B in 36%, C in 21%, and D in 2%. HGS, LFI, PG-SGA and L3-SMI were impaired in 13%, 95%, 21% and 71% respectively. Of all patients, 52% died after (median, range) 373 (32–962) days. Of the nutritional assessment tools, only HGS was independently associated with complication-free survival (HR 0.304, 95%CI 0.10–0.88: p = 0.028) and, approaching significance, with overall survival (HR 0.323, 95%CI 0.103–1.008: p = 0.052). Tumor-specific therapy was administered in 50 patients (20% radiofrequency / microwave ablation, 4% resection, 74% transarterial radio- or chemoembolization, 2% sorafenib). Three months post-treatment, complete response occurred in 44%, partial response in 20%, stable disease in 20% and progressive disease in 16%. Child-Pugh scores deteriorated and such deterioration was independently associated with reduced overall and complication-free survival. Conclusionsreduced baseline HGS and deteriorated post-treatment Child-Pugh score are associated with reduced overall and complication-free survival in HCC.

Severity and prognostic factors of SARS-CoV-2-induced pneumonia: The value of clinical and laboratory biomarkers and the A-DROP score.

IntroductionNumerous clinical and laboratory scores that include C-reactive protein (CRP), D-dimer, ferritin, lactate dehydrogenase (LDH), interleukin 6 (IL-6), procalcitonin (PCT), blood urea nitrogen (BUN), creatinine levels and oxygenation (PaO2 and SaO2) have been used for the prognosis of COVID-19. In addition, composite scores have been developed for the assessment of general state and risk in community-acquired pneumonia (CAP) that may be applied for COVID-19 as well. In this study, we assessed severity and potential prognostic risk factors for unfavorable outcome among hospitalized COVID-19 patients. We also applied the A-DROP general scoring system used in CAP to COVID-19.Patients and methodsAltogether 233 patients admitted to our center with COVID-19 were included in the study. Clinical status, several laboratory biomarkers described above, indicators of oxygenation were determined at hospital admission. We also applied the A-DROP composite scoring system that includes Age (≥ 70 years in males and ≥ 75 years in females), Dehydration (BUN ≥ 7.5 mmol/l), Respiratory failure (SaO2 ≤ 90% or PaO2 ≤ 60 mmHg), Orientation disturbance (confusion) and low blood Pressure (systolic BP ≤ 90 mmHg) to COVID-19.ResultsAt the time of admission, most patients had elevated CRP, LDH, ferritin, D-dimer, and IL-6 levels indicating multisystemic inflammatory syndrome (MIS). Altogether 49 patients (21.2%) required admission to ICU, 46 (19.7%) needed ventilation and 40 patients (17.2%) died. In the binary analysis, admission to ICU, the need for ventilation and death were all significantly associated with the duration of hospitalization, history of hypertension or obesity, confusion/dizziness, as well as higher absolute leukocyte and neutrophil and lower lymphocyte counts, elevated CRP, PCT, LDH, ferritin, IL-6, BUN, and creatinine levels, low PaO2 and SaO2 and higher A-DROP score at the time of admission (p < 0.05).ConclusionNumerous laboratory biomarkers in addition to obesity, dizziness at the time of admission and the history of hypertension may predict the need for ICU admission and ventilation, as well as mortality in COVID-19. Moreover, A-DROP may be a suitable scoring system for the assessment of general health and disease outcome in COVID-19.

Acquired bedaquiline resistance in Karakalpakstan, Uzbekistan.

SUMMARYBACKGROUND:The WHO recommends the use of bedaquiline (BDQ) in longer, as well as shorter, multi-drug-resistant TB (MDR-TB) treatment regimens. However, resistance to this new drug is now emerging. We aimed to describe the characteristics of patients in Karakalpakstan, Uzbekistan, who were treated for MDR-TB and acquired BDQ resistance during treatment.METHODS:We performed a retrospective study of routinely collected data for patients treated for MDR-TB in Karakalpakstan between January 2015 and December 2020. We included patients on BDQ-containing regimens with baseline susceptibility to BDQ who developed BDQ resistance at any point after treatment initiation. Patients resistant to BDQ at baseline or with no confirmed susceptibility to BDQ at baseline were excluded.RESULTS:Of the 523 patients who received BDQ-containing regimens during the study period, BDQ resistance was detected in 31 patients (5.9%); 20 patients were excluded—16 with no prior confirmation of BDQ susceptibility and 4 who were resistant at baseline. Eleven patients with acquired BDQ resistance were identified. We discuss demographic variables, resistance profiles, treatment-related variables and risk factors for unfavourable outcomes for these patients.CONCLUSION:Our programmatic data demonstrated the acquisition of BDQ resistance during or subsequent to receiving a BDQ-containing regimen in a patient cohort from Uzbekistan. We highlight the need for individualised treatment regimens with optimised clinical and laboratory follow up to prevent resistance acquisition.

Childhood encephalitis in the Greater Mekong region (the SouthEast Asia Encephalitis Project): a multicentre prospective study

SummaryBackgroundEncephalitis is a worldwide public health issue, with a substantially high burden among children in southeast Asia. We aimed to determine the causes of encephalitis in children admitted to hospitals across the Greater Mekong region by implementing a comprehensive state-of-the-art diagnostic procedure harmonised across all centres, and identifying clinical characteristics related to patients’ conditions.MethodsIn this multicentre, observational, prospective study of childhood encephalitis, four referral hospitals in Cambodia, Vietnam, Laos, and Myanmar recruited children (aged 28 days to 16 years) who presented with altered mental status lasting more than 24 h and two of the following minor criteria: fever (within the 72 h before or after presentation), one or more generalised or partial seizures (excluding febrile seizures), a new-onset focal neurological deficit, cerebrospinal fluid (CSF) white blood cell count of 5 per mL or higher, or brain imaging (CT or MRI) suggestive of lesions of encephalitis. Comprehensive diagnostic procedures were harmonised across all centres, with first-line testing was done on samples taken at inclusion and results delivered within 24 h of inclusion for main treatable causes of disease and second-line testing was done thereafter for mostly non-treatable causes. An independent expert medical panel reviewed the charts and attribution of causes of all the included children. Using multivariate analyses, we assessed risk factors associated with unfavourable outcomes (ie, severe neurological sequelae and death) at discharge using data from baseline and day 2 after inclusion. This study is registered with ClinicalTrials.gov, NCT04089436, and is now complete.FindingsBetween July 28, 2014, and Dec 31, 2017, 664 children with encephalitis were enrolled. Median age was 4·3 years (1·8–8·8), 295 (44%) children were female, and 369 (56%) were male. A confirmed or probable cause of encephalitis was identified in 425 (64%) patients: 216 (33%) of 664 cases were due to Japanese encephalitis virus, 27 (4%) were due to dengue virus, 26 (4%) were due to influenza virus, 24 (4%) were due to herpes simplex virus 1, 18 (3%) were due to Mycobacterium tuberculosis, 17 (3%) were due to Streptococcus pneumoniae, 17 (3%) were due to enterovirus A71, 74 (9%) were due to other pathogens, and six (1%) were due to autoimmune encephalitis. Diagnosis was made within 24 h of admission to hospital for 83 (13%) of 664 children. 119 (18%) children had treatable conditions and 276 (42%) had conditions that could have been preventable by vaccination. At time of discharge, 153 (23%) of 664 children had severe neurological sequelae and 83 (13%) had died. In multivariate analyses, risk factors for unfavourable outcome were diagnosis of M tuberculosis infection upon admission (odds ratio 3·23 [95% CI 1·04–10·03]), coma on day 2 (2·90 [1·78–4·72]), supplementary oxygen requirement (1·89 [1·25–2·86]), and more than 1 week duration between symptom onset and admission to hospital (3·03 [1·68–5·48]). At 1 year after inclusion, of 432 children who were discharged alive from hospital with follow-up data, 24 (5%) had died, 129 (30%) had neurological sequelae, and 279 (65%) had completely recovered.InterpretationIn southeast Asia, most causes of childhood encephalitis are either preventable or treatable, with Japanese encephalitis virus being the most common cause. We provide crucial information that could guide public health policy to improve diagnostic, vaccination, and early therapeutic guidelines on childhood encephalitis in the Greater Mekong region.FundingInstitut Pasteur, Institut Pasteur International Network, Fondation Merieux, Aviesan Sud, INSERM, Wellcome Trust, Institut de Recherche pour le Développement (IRD), and Fondation Total.
