Conservative management of oesophageal soft food bolus impaction.
No full textBACKGROUND
Impaction of a soft food bolus in the oesophagus causes dysphagia and regurgitation. If the bolus does not pass spontaneously, then the patient is at risk of aspiration, dehydration, perforation, and death. Definitive management is with endoscopic intervention, recommended within 24 hours. Prior to endoscopy, many patients undergo a period of observation, awaiting spontaneous disimpaction, or may undergo enteral or parenteral treatments to attempt to dislodge the bolus. There is little consensus as to which of these conservative strategies is safe and effective to be used in this initial period, before resorting to definitive endoscopic management for persistent impaction.
OBJECTIVES
To evaluate the efficacy of non-endoscopic conservative treatments in the management of soft food boluses impacted within the oesophagus.
SEARCH METHODS
We searched the following databases, using relevant search terms: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and CINAHL. The date of the search was 18 August 2019. We screened the reference lists of relevant studies and reviews on the topic to identify any additional studies.
SELECTION CRITERIA
We included randomised controlled trials of the management of acute oesophageal soft food bolus impaction, in adults and children, reporting the incidence of disimpaction (confirmed radiologically or clinically by return to oral diet) without the need for endoscopic intervention. We did not include studies focusing on sharp or solid object impaction.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures recommended by Cochrane.
MAIN RESULTS
We identified 890 unique records through the electronic searches. We excluded 809 clearly irrelevant records and retrieved 81 records for further assessment. We subsequently included one randomised controlled trial that met the eligibility criteria, which was conducted in four Swedish centres and randomised 43 participants to receive either intravenous diazepam followed by glucagon, or intravenous placebos. The effect of the active substances compared with placebo on rates of disimpaction without intervention is uncertain, as the numbers from this single study were small, and the rates were similar (38% versus 32%; risk ratio 1.19, 95% confidence interval 0.51 to 2.75, P = 0.69). The certainty of the evidence using GRADE for this outcome is low. Data on adverse events were lacking.
AUTHORS' CONCLUSIONS
There is currently inadequate data to recommend the use of any enteral or parenteral treatments in the management of acute oesophageal soft food bolus impaction. There is also inadequate data regarding potential adverse events from the use of these treatments, or from potential delays in definitive endoscopic management. Caution should be exercised when using any conservative management strategies in these patients
Clinical correlates of fatigue in chronic inflammatory demyelinating polyneuropathy.
No full textINTRODUCTION
Fatigue is a recognised manifestation of immune-mediated neuropathies, but its causes and implications are unclear. This study aimed to explore the correlates of fatigue amongst a number of clinical parameters in patients with chronic inflammatory demyelinating polyneuropathy (CIDP), in order to better understand potential contributing factors and resulting consequences.
METHODS
Twenty-six clinically stable CIDP patients underwent assessments of motor and sensory function, disability, quality of life and depression and anxiety. Experienced fatigue was assessed using the Rasch-built fatigue severity scale and Checklist of Individual Strength.
RESULTS
The two utilized fatigue scales showed significant inter-correlation. Only depression scores and grip strength predicted experienced fatigue levels in multivariate regression analyses. Fatigue scores inversely correlated with strength, sensory, disability and quality of life scores.
DISCUSSION
Experienced fatigue is likely multifactorial in CIDP, with both physical and neuropsychiatric components. Fatigue is associated with lower functional and quality-of-life outcomes in CIDP. This article is protected by copyright. All rights reserved

No full textPCTR1 improves pulmonary edema fluid clearance through activating the sodium channel and lymphatic drainage in lipopolysaccharide-induced ARDS.
No full textAcute respiratory distress syndrome (ARDS) is a lethal clinical syndrome characterized by damage of the epithelial barriers and accumulation of pulmonary edema fluid. Protectin conjugates in tissue regeneration 1 (PCTR1), an endogenously produced lipid mediator, are believed to exert anti-inflammatory and pro-resolution effects. PCTR1 (1 µg/kg) was injected at 8 hr after lipopolysaccharide (LPS; 14 mg/kg) administration, and the rate of pulmonary fluid clearance was measured in live rats at 1 hr after PCTR1 treatment. The primary type II alveolar epithelial cells were cultured with PCTR1 (10 nmol/ml) and LPS (1 μg/ml) for 8 hr. PCTR1 effectively improved pulmonary fluid clearance and ameliorated morphological damage and reduced inflammation of lung tissue, as well as improved the survival rate in the LPS-induced acute lung injury (ALI) model. Moreover, PCTR1 markedly increased sodium channel expression as well as Na, K-ATPase expression and activity in vivo and in vitro. In addition, PCTR1i also upregulated the expression of LYVE-1 in vivo. Besides that, BOC-2, HK7, and LY294002 blocked the promoted effect of PCTR1 on pulmonary fluid clearance. Taken together, PCTR1 upregulates sodium channels' expression via activating the ALX/cAMP/P-Akt/Nedd4-2 pathway and increases Na, K-ATPase expression and activity to promote alveolar fluid clearance. Moreover, PCTR1 also promotes the expression of LYVE-1 to recover the lymphatic drainage resulting in the increase of lung interstitial fluid clearance. In summary, these results highlight a novel systematic mechanism for PCTR1 in pulmonary edema fluid clearance after ALI/ARDS, suggesting its potential role in a therapeutic approach for ALI/ARDS
Epidemiology of cannabis use and associated outcomes among kidney transplant recipients: A meta-analysis.
No full textOBJECTIVE
Cannabis is the most commonly used recreational drug in the United States, and transplant acceptability for cannabis using candidates varies among transplant centers. However, the prevalence and impact of cannabis use on outcomes of kidney transplant recipients remain unclear. This study aimed to summarize the prevalence and impact of cannabis use on outcomes after kidney transplantation.
METHODS
A literature search was performed using Ovid MEDLINE, EMBASE, and The Cochrane Library Databases from inception until September 2019 to identify studies assessing the prevalence of cannabis use among kidney transplant recipients, and reported adverse outcomes after kidney transplantation. Effect estimates from the individual studies were obtained and combined utilizing random-effects, generic inverse variance method of DerSimonian-Laird.
RESULTS
A total of four cohort studies with a total of 55 897 kidney transplant recipients were enrolled. Overall, the pooled estimated prevalence of cannabis use was 3.2% (95% CI 0.4%-20.5%). While the use of cannabis was not significantly associated with all-cause allograft failure (OR = 1.31, 95% CI 0.70-2.46) or mortality (OR = 1.52, 95% CI 0.59-3.92), the use of cannabis among kidney transplant recipients was significantly associated with increased death-censored graft failure with pooled OR of 1.72 (95% CI 1.13-2.60).
CONCLUSIONS
The overall estimated prevalence of cannabis use among kidney transplant recipients is 3.2%. The use of cannabis is associated with increased death-censored graft failure, but not mortality after kidney transplantation

No full textChallenges for Liver Transplantation During Recovery From the COVID-19 Pandemic: Insights and Recommendations.
No full textThe coronavirus disease 2019 (COVID-19) pandemic is placing an increasing burden on liver transplant (LT) services worldwide. At the peak of the pandemic, many LT services worldwide reduced or halted their activities. With the gradual easing of lockdowns, LT teams face new challenges when restarting activities. The numbers of LTs are likely to drop in the immediate post-COVID era. Prolonged and intermittent lockdowns are likely to lead to a shortage of supplies, especially in poor resource settings. Special attention is needed to avoid nosocomial COVID-19 infection among cirrhotic patients awaiting transplant, post-transplant patients, and members of transplant teams. LT programs may have to revise existing strategies in selecting donors and recipients for transplants. Redesigning service provision, restructuring outpatient care, carefully screening and selecting donors and recipients, and performing LT with limited resources will have to be initiated in the post-COVID era if long-term recovery of LT services is to be expected. Costs involved with LT are likely to increase, considering the change in protocols of testing, quarantining, and interstate traveling. This paper discusses the different elements affecting and the widespread impact of the COVID-19 pandemic on LT and strategies to minimize the impact of these factors and to adapt so LT services can meet the health care needs during this pandemic and beyond
The Automated Bone Scan Index as a Predictor of Response to Prostate Radiotherapy in Men with Newly Diagnosed Metastatic Prostate Cancer: An Exploratory Analysis of STAMPEDE's "M1|RT Comparison".
No full textBACKGROUND
Prostate radiotherapy (RT) is a first-line option for newly diagnosed men with low-burden metastatic prostate cancer. The current criterion to define this clinical state is based on manual bone metastasis counts, but enumeration of bone metastases is limited by interobserver variations, and it does not account for metastasis volume or lesional coalescence. The automated bone scan index (aBSI) is a quantitative method of evaluating bone metastatic burden in a standardised and reproducible manner.
OBJECTIVE
To evaluate whether aBSI has utility as a predictive imaging biomarker to define a newly diagnosed metastatic prostate cancer population that might benefit from the addition of prostate RT to standard of care (SOC) systemic therapy.
DESIGN, SETTING, AND PARTICIPANTS
This is an exploratory analysis of men with newly diagnosed metastatic prostate cancer randomised in a 1:1 ratio to either SOC or SOC + prostate RT within the STAMPEDE "M1|RT comparison".
INTERVENTION
The SOC was lifelong androgen deprivation therapy, with up-front docetaxel permitted from December 2015. Men allocated RT received either a daily or a weekly schedule that was nominated before randomisation.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS
Baseline bone scans were evaluated retrospectively to calculate aBSI. We used overall (OS) and failure-free (FFS) survival as the end points. Treatment-aBSI interaction was evaluated using the multivariable fractional polynomial interaction (MFPI) and subpopulation treatment effect pattern plot. Further analysis was done in aBSI quartiles using Cox regression models adjusted for stratification factors.
RESULTS AND LIMITATIONS
Baseline bone scans for 660 (SOC: 323 and SOC + RT: 337) of 2061 men randomised within the "M1|RT comparison" met the software requirements for aBSI calculation. The median age was 68 yr, median PSA was 100 ng/mL, median aBSI was 0.9, and median follow-up was 39 mo. Baseline patient characteristics including aBSI were balanced between the treatment groups. Using the MFPI procedure, there was evidence of aBSI-treatment interaction for OS (p = 0.04, MFPI procedure) and FFS (p < 0.01, MFPI procedure). Graphical evaluation of estimated treatment effect plots showed that the OS and FFS benefit from prostate RT was greatest in patients with a low aBSI. Further analysis in quartiles based on aBSI supported this finding.
CONCLUSIONS
A low automated bone scan index is predictive of survival benefit associated with prostate RT in men with newly diagnosed metastatic prostate cancer.
PATIENT SUMMARY
The widely used bone scan can be evaluated using an automated technique to potentially select men with newly diagnosed metastatic prostate cancer who might benefit from prostate radiotherapy
