Background: This study analysed children with end-stage renal disease treated with automated peritoneal dialysis (APD) in our centre to explore the risk factors associated with residual renal function (RRF) loss. Methods: Children treated with APD as the initial renal replacement therapy regimen from January 2008 to December 2016 were included. All the children had a daily urine volume of ≥100 ml/m2 when APD was initiated and a dialysis follow-up time of ≥12 months. A daily urine volume of <100 ml/m2 after 12 months of APD treatment was defined as loss of RRF. Possible risk factors that may be associated with RRF loss were analysed. Results: A total of 66 children were included in the study. After 12 months of APD treatment, the daily urine volume decreased by 377.45 ± 348.80 ml/m2, the residual glomerular filtration rate decreased by 6.39 ± 3.69 ml/min/1.73 m2 and 29 of the patients (43.9%) developed RRF loss. The higher risk of RRF loss after 1 year of APD treatment was most pronounced in patients with daily urine volume of ≤400 ml/m2 before treatment, higher glucose exposure and higher ultrafiltration volume, while the lower risk of RRF loss was in patients with administration of diuretics. Each increase of 1 g/m2/day glucose exposure was associated with a 5% increase in RRF loss (odds ratio (OR) 1.05, p = 0.023) and each increase of 1 ml/m2/day ultrafiltration volume was associated with a 1% increase in RRF loss (OR 1.01, p = 0.013). Conclusion: In children undergoing APD, the risk for loss of RRF is associated with low urine volume at the start of APD, high glucose loading and high peritoneal ultrafiltration volume, while preservation of RRF is associated with the usage of diuretics.
2005 Guidelines on targets for solute and fluid removal in adults being treated with chronic peritoneal dialysis: 2019 Update of the literature and revision of recommendations
Authors: Boudville Neil , de Moraes Thyago Proença 
Published: February 2020

Background: The International Society for Peritoneal Dialysis guidelines for small solute clearance and fluid removal in peritoneal dialysis (PD) were published in 2005. The aim of this article is to update those guidelines by reviewing the literature that supported those guidelines and examining publications since then. Methods: An extensive search of publications was performed through electronic databases and a hand search through reference lists from the existing guideline and selected articles. Results: There have been no prospective intervention trials to inform the area of small solute clearance in PD since the publication of the original guideline in 2005. The trials to date are largely limited to a few prospective cohort studies and retrospective studies. These have, however, consistently demonstrated that residual renal function (RRF) is more often associated with patient outcome than peritoneal clearance. One of the few randomised controlled trials performed in this area does suggest that a weekly Kt/ V of 2.27 ± 0.02 provides no statistically significant survival advantage over a weekly Kt/ V of 1.80 ± 0.02. The lower limit of Kt/ V is unknown but there is weak evidence to suggest that anuric people doing PD should have a weekly Kt/ V of at least 1.7. Conclusions: There continues to be very poor evidence in the area of small solute clearance and fluid removal in PD. The evidence that exists suggests that RRF is more important than peritoneal clearance and that there appears to be no survival advantage in aiming for a weekly Kt/ V >1.70.

Published: February 2020

Background: Particulated juvenile cartilage allograft transfer (PJCAT) is an emerging treatment option for management of osteochondral lesions of the talus (OCLTs). This series reports on outcomes and identifies predictors for success following PJCAT for isolated OCLTs. Methods: We reviewed 33 consecutive patients who underwent PJCAT by a single surgeon from 2013 to 2017. Preoperative demographic factors (age, body mass index [BMI], tobacco use, behavioral health comorbidity, and ankle pain visual analog score [VAS]) and OCLT morphologic data were collected. Outcomes included postoperative improvements in VAS and American Orthopaedic Foot & Ankle Society (AOFAS) score and clinical success/failure. Results of 7 second-look arthroscopies and complications are provided. Categorical data are reported as frequencies, and statistical means with P values are reported for continuous variables. We had a mean 3.5 years of follow-up. Results: Improvement in ankle pain VAS following isolated PJCAT was 51% ( P < .001). For the first 16 consecutive patients in whom complete AOFAS scores were available, 40% ( P < .001) improvement occurred. Presence of 1 or more behavioral health diagnoses was a risk factor for decreased pain relief, while moderate to severe preoperative pain (VAS >5.9) predicted improved postoperative pain relief. Age, BMI, tobacco use, and OCLT morphology did not affect outcomes. Conclusion: For treatment of large, high-stage OCLTs, PJCAT resulted in 40% to 50% improvement in ankle pain and disability within 3.5 years. The results may be better in patients with moderate to severe preoperative pain but worse in those with preexisting behavioral health diagnoses. Level of Evidence: Level IV, retrospective case series.

Introduction Oral cavity malignancies constitute 30% of head and neck cancers. The most common distant metastatic sites of glottic carcinoma are usually lung, liver and bone. Although the cutaneous metastasis of head and cancers have been reported with an incidence of 0.7–2.4%, skin metastasis of glottic carcinoma is extremely rare. Case report A 69-year-old male patient was admitted to the emergency department with hemoptysis, dyspnea, weakness in lower extremities and difficulty in swallowing. There were subcutaneous lesions with a diameter of 2–5 cm in the scalp, posterior chest wall, nose and abdomen. In addition, there was an ulcerating, painful mass on the right lateral part of the tongue. The biopsy of lesions on tongue and skin revealed a glottic squamous cell carcinoma with cutaneous metastasis. Management and outcome: The patient was treated with cisplatin 50 mg/m2 on day 1, cetuximab 500 mg/m2 on day 1 and 5-fluorouracil 1000 mg/m2 daily on days 1 and 2, repeated every two weeks. After the first cycle of chemotherapy, the lesions on the skin regressed and dysphagia improved. Discussion There are limited data about the incidence, diagnostic measures and treatment modalities of glottic cancer with cutaneous metastasis. Our case could provide an important experience to literature by its atypical presentation and treatment-sensitive nature.

Introduction Multiple myeloma is a malignant neoplasm of plasma cells. Lenalidomide-dexamethasone treatment is a common treatment regimen used in refractory multiple myeloma. Case report We describe the case of a 58-year-old male multiple myeloma patient with a history of relapse after six months of autologous stem cell transplantation. The patient had nausea and bloody diarrhea developed during lenalidomide treatment. Management and outcome: Computed tomography showed diffuse marked edematous thickness in the wall of colonic, hepatic and splenic flexure, transverse colon, descending colon and sigmoid colon. Colonoscopic observation revealed highly granular, hyperemic and fragile mucosa. Colon biopsy was consistent with ischemic colitis. Lenalidomide treatment was discontinued. One month later, colon findings were detected as normalized through a colonoscopy. Discussion Risk of developing ischemic colitis should be kept in mind in patients receiving lenalidomide which should be discontinued in cases with severe bloody diarrhea of unknown origin.

Objectives The aim of this study was to analyse the frequency of oral cavity lesions in cats, their anatomical location and histological diagnosis, and the effect of life stage, breed and sex on different diagnoses. Methods For this purpose, a retrospective study comprising 297 feline oral cavity lesions was performed over a 6-year period between 2010 and 2015. Histopathological records from the DNAtech Pathology Laboratory (Lisbon, Portugal) were analysed. Results The incidence of oral disease was higher in male cats (n = 173; 58.4%), mature adults (ranging from 7 to 10 years old [n = 88; 33.0%]) and in the European Shorthair breed (n = 206; 73.6%). The gingiva was the site where oral lesions were most commonly found, with 128 samples (43.1%). Incisional biopsies were used to obtain the majority of samples (n = 256; 86.2%), while excisional biopsies and punch biopsies were performed in 36 (12.1%) and five (1.7%) cases, respectively. Inflammatory and neoplastic lesions accounted for 187 (63%) and 110 (37%) of the studied cases, respectively. Malignancies were found in >80% of neoplastic cases. Feline chronic gingivostomatitis was the most common histological diagnosis (n = 116; 39.1%), followed by squamous cell carcinoma (n = 49; 16.5%) and eosinophilic granuloma complex (n = 33; 11.1%). Conclusions and relevance The present work, involving a large series of samples of feline oral cavity lesions, from numerous geographically scattered practices and all examined at a reference veterinary pathology laboratory, adds important new understanding of the epidemiology of feline oral disease.

Published: February 2020

Purpose: To explore the clinical value of ultrasound in the diagnosis of medullary thyroid carcinoma by comparing with enhanced computed tomography. Methods: This retrospective study was performed on 62 patients with pathologically confirmed medullary thyroid carcinoma. All patients underwent ultrasound and enhanced computed tomography examinations before surgery. The findings of the pathologic examination of resected specimens were considered as gold standard and were compared with the results of these 2 methods. Results: There were 73 medullary thyroid carcinoma lesions and 29 benign lesions in 62 patients. In all, 55 of 73 medullary thyroid carcinoma lesions and 27 of 29 benign lesions were correctly diagnosed by ultrasound; and 45 of 73 medullary thyroid carcinoma lesions and 24 of 29 benign lesions were correctly diagnosed by enhanced computed tomography. The accuracy of ultrasound and enhanced computed tomography was 80.4% and 67.6%, respectively. There was significant difference between 2 methods ( P < .05). Conclusions: Ultrasound can be used to observe the location, number, size, shape, border, internal echo, calcification, and blood flow of the lesion. It is a convenient, inexpensive, and nonradiative method with higher accuracy than enhanced computed tomography.

Introduction Missing outcome data may undermine interpretation of randomised clinical trials by weakening power and limiting apparent effect size. We assessed bias and inefficiency of two imputation methods commonly used in stroke trials evaluating the efficacy of iv thrombolysis. Patients and methods We searched the virtual international stroke trials archive (VISTA)-acute for ischaemic stroke patients with 90-day modified Rankin scale as an outcome, and known thrombolysis status. We excluded any with missing 30-day modified Rankin scale. We planned two analyses; first, we calculated odds ratios for outcome in thrombolysed versus not thrombolysed from imputed-only data, (a) among patients with missing modified Rankin scale 90 and (b) among matched patients with intact data (using propensity score methods and relevant covariates). Imputation approaches were last observation carried forward (LOCF) or multiple imputation. Outcome comparisons used dichotomisation and shift analysis. Thereafter, we calculated whole-population odds ratios using LOCF and multiple imputation (also through dichotomisation and shift analysis); first with the original 1.5% missing outcome data, and then artificially increasing the burden (5%; 10%; 20%; 30%). Results We considered 9657 patients from eight of the studies included in VISTA, 3034 (31%) thrombolysed. Missing data replacement by LOCF with analysis by dichotomisation gave the highest estimate of thrombolysis influence. Imputing while increasing the burden of missing data progressively raised the odds ratios estimates, though thresholds for overestimation were 10% for LOCF; 20% for multiple imputation. Discussion: Replacing missing outcome data tended to overestimate differences of thrombolysed versus non-thrombolysed patients, but had minimal impact below a 10% burden of missing data. Conclusion: In the specific context of acute stroke trials testing iv thrombolytics, replacing missing data by carrying forward the last observation tended to overestimate treatment odds ratios more than multiple imputation.

Published: February 2020

AbstractBackgroundThe study objective was to test the hypothesis that 1) lowering dietary crude protein (CP) increases dietary energetic efficiency and reduces metabolic heat associated with lactation, and 2) excessive dietary leucine (Leu) supplementation in a low CP diet decreases dietary energetic efficiency and increases metabolic heat associated with lactation.MethodsFifty-four lactating multiparous Yorkshire sows were allotted to 1 of 3 isocaloric diets (10.80 MJ/kg net energy): 1) control (CON; 18.75% CP), 2) reduced CP with a near ideal or optimal AA profile (OPT; 13.75% CP) and 3) diet OPT with excessive Leu (OPTLEU; 14.25% CP). Sow body weight and backfat were recorded on day 1 and 21 of lactation and piglets were weighed on day 1, 4, 8, 14, 18, and 21 of lactation. Energy balance was measured on sows during early (day 4 to 8) and peak (day 14 to18) lactation, and milk was sampled on day 8 and 18.ResultsOver 21-day lactation, sows fed OPT lost body weight and body lipid (P < 0.05). In peak lactation, sows fed OPT had higher milk energy output (P < 0.05) than CON. Sows fed OPTLEU tended (P = 0.07) to have less milk energy output than OPT and did not differ from CON. Maternal energy retention was lower (P < 0.05) in OPT and OPTLEU compared to CON sows, and did not differ between OPTLEU and OPT sows. Sows fed OPT had higher (P < 0.05) apparent energy efficiency for milk production compared to CON. Heat production associated with lactation was lower (P < 0.05) or tended to be lower (P = 0.082), respectively, in OPT and OPTLEU compared to CON sows.ConclusionThe OPT diet, in peak lactation, improved dietary energy utilization for lactation due to less urinary energy and metabolic heat loss, and triggered dietary energy deposition into milk at the expense of maternal lipid mobilization. Leucine supplementation above requirement may reduce dietary energy utilization for lactation by decreasing the energy partitioning towards milk, partially explaining the effectiveness of OPT diet over CON diets.

Abstract
Background
Loiasis is an uncommon and poorly understood parasitic disease outside endemic areas of Africa. The aim of this study was to describe the clinical and biological patterns and treatment of imported loiasis by sub-Saharan migrants diagnosed in Madrid, Spain.

Methods
A retrospective study was conducted with sub-Saharan immigrants seen at the Tropical Medicine Unit of the Carlos III Hospital in Madrid, Spain, a reference center, over 19 years. Categorical variables were expressed as frequency counts and percentages. Continuous variables were expressed as the mean and standard deviation (SD) or median and interquartile range (IQR: Q3–Q1). Chi-square tests were used to assess the association between categorical variables. The measured outcomes were expressed as the odds ratio (OR) with a 95% confidential interval. Continuous variables were compared by Student’s t-tests or Mann-Whitney U tests. Binary logistic regression models were used. P <  0.05 was considered a statistically significant difference.

Results
One hundred thirty-one migrants from tropical and subtropical areas with loiasis were identified. Forty-nine patients were male (37.4%). The migrants’ mean age (±SD) was 42.3 ± 17.3 years, and 124 (94.7%) were from Equatorial Guinea. The median time (IQR) between arrival in Spain and the first consultation was 2 (1–7) months. One hundred fifteen migrants had eosinophilia, and one hundred thirteen had hyper-IgE syndrome. Fifty-seven patients had pruritus (43.5%), and thirty patients had Calabar swelling (22.9%). Seventy-three patients had coinfections with other filarial nematodes (54.2%), and 58 migrants had only Loa loa infections (45.8%). One hundred two patients (77.9%) were treated; 45.1% (46/102) patients were treated with one drug, and 54.9% (56/102) patients were treated with combined therapy. Adverse reactions were described in 14 (10.7%) migrants.

Conclusions
Our patients presented early clinical manifestations and few atypical features. Thus, physicians should systematically consider loiasis in migrants with a typical presentation. However, considering that 72.5% of the patients had only positive microfilaremia without any symptoms, we suggest searching for microfilaremia in every migrant from endemic countries for loiasis presenting with eosinophilia.

Published: February 2020

AbstractBackgroundIndividual compliances of the foot-shoe interface have been suggested to store and release elastic strain energy via ligamentous and tendinous structures or by increased midsole bending stiffness (MBS), compression stiffness, and resilience of running shoes. It is unknown, however, how these compliances interact with each other when the MBS of a running shoe is increased. The purpose of this study was to investigate how structures of the foot-shoe interface are influenced during running by changes to the MBS of sport shoes.MethodsA randomised crossover trial was performed, where 13 male, recreational runners ran on an instrumented treadmill at 3.5 m·s−1while motion capture was used to estimate foot arch, plantar muscle-tendon unit (pMTU), and shank muscle-tendon unit (sMTU) behaviour in two conditions: (1) control shoe and (2) the same shoe with carbon fibre plates inserted to increase the MBS.ResultsRunning in a shoe with increased MBS resulted in less deformation of the arch (mean ± SD; stiff, 7.26 ± 1.78°; control, 8.84 ± 2.87°;p ≤ 0.05), reduced pMTU shortening (stiff, 4.39 ± 1.59 mm; control, 6.46 ± 1.42 mm;p ≤ 0.01), and lower shortening velocities of the pMTU (stiff, − 0.21 ± 0.03 m·s−1; control, − 0.30 ± 0.05 m·s−1;p ≤ 0.01) and sMTU (stiff, − 0.35 ± 0.08 m·s−1; control, − 0.45 ± 0.11 m·s−1;p ≤ 0.001) compared to a control condition. The positive and net work performed at the arch and pMTU, and the net work at the sMTU were significantly lower in the stiff compared to the control condition.ConclusionThe findings of this study showed that if a compliance of the foot-shoe interface is altered during running (e.g. by increasing the MBS of a shoe), the mechanics of other structures change as well. This could potentially affect long-distance running performance.
Customized registry tool for tracking adherence to clinical guidelines for head and neck cancers: protocol for a pilot study

Published: February 2020

Abstract
Background
Despite recommendations for monitoring patients with chronic and high-risk conditions, gaps still remain. These gaps are exacerbated in outpatient care, where patients and clinicians face challenges related to care coordination, multiple electronic health records, and extensive follow-up. In addition, low-income and racial/ethnic minority populations that are disproportionately cared for in safety net settings are particularly at risk to lapses in monitoring.

Methods
We aim to implement and evaluate a health information technology platform developed using systems engineering methodologies. The implementation is situated in a clinic that monitors patients with head and neck cancer within a large, urban, publicly funded hospital. Our study will evaluate the time it takes for patients to progress through key treatment milestones prior to and after implementation of the tool. We will use models controlling for secular trend to estimate the effect of the tool on improving timely and successful completion of guideline-based care processes.

Discussion
This protocol details the evaluation of the effectiveness of a human-centered health information technology intervention on improving timely delivery of care for high-risk populations. Other settings, including those that face challenges related to limited resources to devote to safety programs and fragmented health information technology, may benefit from this approach.
