OBJECTIVES To assess 1-week and 1-month efficacy of Systane iLux thermal pulsation treatment for meibomian gland dysfunction (MGD). METHODS This prospective, nonrandomized, open-label, multicenter study enrolled 30 adult patients (60 eyes) who had a Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire score greater than 6 and total meibomian gland secretion (MGS) score equal to or less than 12 in each eye. All participants received thermal pulsation treatment bilaterally. Primary efficacy measures included MGS score (sum of grades for 15 glands graded on a scale of 0-3; 0 [no secretion], 1 [inspissated], 2 [cloudy], and 3 [clear liquid]) and tear breakup time (TBUT). Secondary efficacy measures were SPEED and Ocular Surface Disease Index (OSDI) scores. RESULTS The mean age of patients was 52.9±11.9 years. After 1 week, the mean MGS score improved significantly from 4.1±3.1 to 15.8±7.1 (right eye, OD) and 3.7±3.1 to 16.7±7.6 (left eye, OS); mean TBUT improved significantly from 4.9±4.1 to 8.4±3.6 (OD) and 5.2±4.2 to 8.9±3.9 (OS); and mean SPEED and OSDI scores improved significantly from 16.1±5.3 to 7.2±6.1 and 45.2±21.3 to 19.0±16.8, respectively (all P

Background Acute portal vein thrombosis is a major cause of fulminant allograft failure in pediatric liver transplantation. Timely intervention is critical to save the graft and patient. Serial interventional radiologic management of this condition is scarcely reported in the literature. Case Summary A recently transplanted 17-year-old male presented to the emergency department with abdominal pain. Rising liver enzymes prompted discovery of a diffuse portal thrombus, which precipitated fulminant liver failure. The adolescent developed respiratory failure, vasodilatory shock, acute kidney injury, and hepatic encephalopathy, complicating treatment. Multiple interventions attempted to clear the thrombus, including interventional radiologic and medical therapies. Uniquely, a continuous infusion catheter was placed at the thrombosis, delivering local tissue plasminogen activator during a 5-day period. Upon thrombus clearance, the patient made a full recovery with no complications during 12 months of follow-up. Conclusions When used as a component of multidisciplinary management, continuous locally directed tissue plasminogen activator may be a useful tool for clearance of persistent portal vein thrombosis.

Pneumonia is one of the most common infectious diseases and the fourth leading cause of death globally. According to US statistics in 2019, pneumonia is the most common cause of sepsis and septic shock. In the US, inpatient pneumonia hospitalizations account for the top 10 highest medical costs, totaling $9.5 billion for 960,000 hospital stays. The emergence of antibiotic resistance in the treatment of infectious diseases, including the treatment of pneumonia, is a globally alarming problem. Antibiotic resistance increases the risk of death and re-hospitalization, prolongs hospital stays, and increases treatment costs, and is one of the greatest threats in modern medicine. Drug-related problems (DRPs) in pneumonia - such as suboptimal antibiotic indications, prolonged treatment duration, and drug interactions - increase the rate of antibiotic resistance and adverse effects, thereby leading to an increased burden in treatment. In a context in which novel and effective antibiotics are scarce, mitigating DRPs in order to reduce antibiotic resistance is currently a prime concern. A variety of interventions proven useful in reducing DRPs are antibiotic stewardship programs, the use of biomarkers, computerized physician order entries and clinical decision support systems, and community-acquired pneumonia scores.

This study was conducted to determine the prevalence and determinants of medication adherence among patients with HIV/AIDS in southern Vietnam. Methods: A cross-sectional study was conducted in a hospital in southern Vietnam from June to December 2019 on patients who began antiretroviral therapy (ART) for at least 6 months. Using a designed questionnaire, patients were considered adherent if they took correct medicines with right doses, on time and properly with food and beverage and had follow-up visits as scheduled. Multivariable logistic regression was used to identify determinants of adherence. Key findings: A total of 350 patients (from 861 medical records) were eligible for the study. The majority of patients were male (62.9%), and the dominant age group (≥35 years old) accounted for 53.7% of patients. Sexual intercourse was the primary route of transmission of HIV (95.1%). The proportions of participants who took the correct medicine and at a proper dose were 98.3% and 86.3%, respectively. In total, 94.9% of participants took medicine appropriately in combination with food and beverage, and 75.7% of participants were strictly adherent to ART. The factors marital status (odds ratio (OR) = 2.54, 95%CI = 1.51–4.28), being away from home (OR = 1.7, 95%CI = 1.03–2.78), substance abuse (OR = 2.7, 95%CI = 1.44–5.05), general knowledge about ART (OR = 2.75, 95%CI = 1.67–4.53), stopping medication after improvement (OR = 4.16, 95%CI = 2.29–7.56) and self-assessment of therapy adherence (OR = 9.83, 95%CI = 5.44–17.77) were significantly associated with patients’ adherence. Conclusions: Three-quarters of patients were adherent to ART. Researchers should consider these determinants of adherence in developing interventions in further studies.

The field of liver transplantation has shifted considerably in the MELD era, including changing allocation, immunosuppression, and liver failure etiologies, as well as better supportive therapies. Our aim was to evaluate the predictive accuracy of the MELD score over time. The United Network for Organ Sharing provided de-identified data on 120 156 patients listed for liver transplant from 2002-2016. The ability of the MELD score to predict 90-day mortality was evaluated by a concordance (C-) statistic and corroborated with competing risk analysis. The MELD score's concordance with 90-day mortality has downtrended from 0.80 in 2003 to 0.70 in 2015. While lab MELD scores at listing and transplant climbed in that interval, score at waitlist death remained steady near 35. Listing age increased from 50 to 54 years. HCV-positive status at listing dropped from 33 to 17%. The concordance of MELD and mortality does not differ with age (>60 = 0.73

Background The aim of this study was to assess improvements in long-term survival of pediatric patients after liver transplantation by analyzing outcomes in transplant recipients who survived beyond 1 year after transplantation. There has been a marked increase in the 1-year survival of pediatric patients, from 78% in transplant recipients between 1987 and 1990 to 95% in transplant recipients between 2011 and 2017. The long-term outcomes have not seen a similar trend, creating a disparity that warrants analysis. Methods We analyzed 13 753 pediatric patients who survived for 1 year after receiving orthotopic liver transplantation between 1987 and 2017. The study period was divided into six eras. Outcomes were analyzed using the Kaplan-Meier method for time-to-event analysis, and multivariable Cox regression. Results There were no significant gains in long-term outcomes among 1-year survivors over the past three decades. Log-rank tests for equality of survivor functions between each era and 1987-1990 were not statistically significant. Cause of death analysis revealed that although infections caused 20.6% of deaths in patients transplanted between 1987 and 1990, this number dropped to 5.6% in those transplanted between 2011 and 2017 (p = .01). Malignancy caused 10.6% of deaths in 1987-1990 but caused 22.2% of the deaths in 2011-2017 (p = .04). Conclusion Despite the gratifying gains in short-term survival of pediatric patients, 1-year survivors have no significant improvements in long-term survival after undergoing a liver transplantation. Long-term sequelae of immunosuppression, such as malignancy and infection, continue to be the most common causes of death. This study highlights the necessity for better long-term management of immunosuppression.

Significance Quantifying meibomian gland morphology from meibography images is used for the diagnosis, treatment, and management of meibomian gland dysfunction in clinics. A novel and automated method is described for quantifying meibomian gland morphology from meibography images. Purpose Meibomian gland morphological abnormality is a common clinical sign of meibomian gland dysfunction, yet there exist no automated methods that provide standard quantifications of morphological features for individual glands. This study introduces an automated artificial intelligence approach to segmenting individual meibomian gland regions in infrared meibography images and analyzing their morphological features. Methods A total of 1443 meibography images were collected and annotated. The dataset was then divided into development and evaluation sets. The development set was used to train and tune deep learning models for segmenting glands and identifying ghost glands from images, whereas the evaluation set was used to evaluate the performance of the model. The gland segmentations were further used to analyze individual gland features, including gland local contrast, length, width, and tortuosity. Results A total of 1039 meibography images (including 486 upper and 553 lower eyelids) were used for training and tuning the deep learning model, whereas the remaining 404 images (including 203 upper and 201 lower eyelids) were used for evaluations. The algorithm on average achieved 63% mean intersection over union in segmenting glands, and 84.4% sensitivity and 71.7% specificity in identifying ghost glands. Morphological features of each gland were also fed to a support vector machine for analyzing their associations with ghost glands. Analysis of model coefficients indicated that low gland local contrast was the primary indicator for ghost glands. Conclusions The proposed approach can automatically segment individual meibomian glands in infrared meibography images, identify ghost glands, and quantitatively analyze gland morphological features.

Background The aim of this study is to describe the incidence and impact of reoperation following pediatric liver transplantation, as well as the indications and risk factors for these complications. Methods All primary pediatric liver transplants performed at our institution between January 2012 and September 2016 were reviewed. A reoperative complication was defined as a complication requiring return to the operating room within 30 days or the same hospital admission as the transplant operation, excluding retransplantation. Results Among the 144 pediatric liver transplants performed during the study period, 9% of the recipients required reoperation. The most common indications for reoperation were bleeding and bowel complications. There was no significant difference in the graft survival of patients with a reoperation and those without a reoperation (p = 0.780), but patients with a reoperation had a significantly longer hospital length of stay (median of 39 days vs. 11 days, p = 0.001). Variant donor arterial anatomy, transplant operative time, intraoperative blood loss, transfusion volume of packed red blood cells or cell saver per weight, and transfusion with fresh frozen plasma, platelets, or cryoprecipitate were significantly associated with reoperation upon univariable logistic regression, but none of these risk factors remained statistically significant upon multivariable regression. Conclusion At our institution, reoperation did not significantly impact graft survival. We identified variant donor arterial anatomy, transplant operative time, intraoperative blood loss, transfusion volume of packed red blood cells or cell saver per weight, and transfusion with fresh frozen plasma, platelets, or cryoprecipitate as risk factors for reoperation, although none of these risk factors demonstrated independent association with reoperation in a multivariable model. Type of study Prognosis Study. Level of evidence Level III.

Author(s): Yeh, Thao N; Lin, Meng C | Abstract: SignificanceLipid deficiency due to meibomian gland (MG) dysfunction is believed to account for the vast majority of patients with dry eye compared with aqueous deficiency. Clinicians commonly evaluate MG length to determine a disease, but our research with isotretinoin users suggests that MG contrast is also an important characteristic to consider.PurposeThis study aimed to determine the sensitivity and specificity of MG contrast for the diagnosis of lipid-deficient dry eye (LDDE).MethodsThis case-control study used demographic data, Standard Patient Evaluation of Eye Dryness (SPEED) scores, average tear lipid layer thickness (TLLT), fluorescein tear breakup time (FTBUT), upper eyelid meibography images, and meibum quality and quantity scores for individuals with LDDE (SPEED score ≥10 and TLLT ≤35 interferometric color units) and normal individuals (SPEED ≤2 and TLLT ≥80 interferometric color units).ResultsThirty-one eyes of 22 controls (mean ± SD age, 22.7 ± 5.5 years) and 13 eyes of 12 cases (mean ± SD age, 43.9 ± 17.2 years) were included. Normalized MG contrast was significantly correlated with FTBUT (r = 0.35, P = .02), percent MG atrophy (r = -0.50, P l .001), and SPEED scores (r = -0.49, P l .001). The receiver operating characteristic curve for LDDE diagnosis classifiers MG contrast, MG atrophy, and meibum quantity score had areas under the curve of 0.83, 0.64, and 0.73, respectively. Meibomian gland contrast cutoff at 28.3 intensity units yielded optimal correct classification of subjects (84.1%; sensitivity, 0.69; specificity, 0.90). Cases had shorter FTBUT (P l .001), worse meibum quality (P = .02) and quantity (P = .02) scores, and lower MG contrast (P l .001) compared with controls. Subjects with low MG contrast (≤28.3) had 14.9 higher odds of having LDDE (95% confidence interval, 2.84 to 78.4) compared with subjects with high MG contrast (g28.3).ConclusionsMeibomian gland contrast correlates well with clinical parameters and symptoms, shows good sensitivity and excellent specificity for diagnosing LDDE, and can be a useful diagnostic parameter for monitoring MG changes due to age, disease, or intervention.

Background Successful liver transplantation is dependent on restoration of hepatic arterial (HA) flow. Although uncommon, some native recipient HAs are not suitable or inadequate for anastomosis, thereby necessitating extra-anatomic HA reconstruction. Splenic artery transposition (SAT) is 1 method of HA reconstruction, in which the recipient splenic artery is transposed to reestablish perfusion of the donor liver. Due to the rarity of the technique, literature describing outcomes is limited. In the current report, we describe 3 patients (2 adults, 1 pediatric) who underwent complex upper abdominal surgery before whole-organ deceased donor liver transplantation with SAT. Methods The demographic and patient care information was collected prospectively and subsequently reviewed retrospectively. Given the de-identified nature of the data included, this study was exempt from approval from an ethics board. Results Recipient splenic arteries were dissected from their origin at the celiac trunk, for approximately 3-5 cm to ensure a gentle anterior-cranial curve toward the right upper quadrant, allowing anastomosis to the donor celiac trunk in an end-to-end fashion. Postoperatively, all 3 patients had rapid normalization of liver function tests and brisk HA flow demonstrated by Doppler ultrasound. Longer-term follow-up, ranging from 1 to 3 years, reveals continued patency of the reconstructed HAs and liver function tests within normal limits. Conclusions Our experience points to SAT as a safe and effective technique for extra-anatomic HA reconstruction.

Background: The Coronavirus 2019 pandemic has posed a particular challenge for transplant programs across the world as little was understood regarding how the virus would affect immunocompromised hosts. In addition it was unclear if race and socioeconomic status affected hospitalization rates. Methods: We describe a cohort of 25 solid organ transplant recipients (SOTR) within a single-center who were subsequently hospitalized for COVID-19 infection. In addition, we compared baseline characteristics of our cohort with all of our transplants from 1/2/2015 until 11/5/2020. Results: Transplant recipients infected with COVID-19 have many comorbidities (96% with hypertension, 60% with heart failure or ischemic heart disease, and 60% with diabetes). Overall SOTR patients frequently presented with AKI (44%), frequently required ICU stay (52%), and frequently required intubation (36%). We discovered a statistically significant racial disparity in COVID-19 infection in minorities within our cohort compared to our baseline transplant recipient population. Conclusion: Transplant recipients tended to have more atypical symptoms such as diarrhea and tolerated a stepwise reduction of immunosuppression. Solid organ transplant recipients - particularly minorities and low income patients-may benefit from additional COVID-19 precautions such as earlier access to vaccination.

Background The clinical course of COVID‐19 in pediatric solid organ transplant recipients remains ambiguous. Though preliminary experiences with adult transplant recipients have been published, literature centered on the pediatric population is limited. We herein report a multi‐center, multi‐organ cohort analysis of COVID‐19 positive transplant recipients ≤ 18 years at time of transplant. Methods Data were collected via institutions’ respective electronic medical record systems. Local review boards approved this cross‐institutional study. Results Among 5 transplant centers, 26 patients (62% male) were reviewed with a median age of 8 years. 6 were heart recipients, 8 kidney, 10 liver, and 2 lung. Presenting symptoms included cough (n=12 (46%)), fever (n=9 (35%)), dry/sore throat (n=3 (12%)), rhinorrhea (n=3 (12%)), anosmia (n=2 (8%)), chest pain (n=2 (8%)), diarrhea (n=2 (8%)), dyspnea (n=1 (4%)), and headache (n=1 (4%)). Six patients (23%) were asymptomatic. No patient required supplemental oxygen, intubation, or ECMO. Eight patients (31%) were hospitalized at time of diagnosis, 3 of whom were already admitted for unrelated problems. Post‐transplant immunosuppression was reduced for only 2 patients (8%). All symptomatic patients recovered within 7 days. Conclusions Our multi‐institutional experience suggests the prognoses of pediatric transplant recipients infected with COVID‐19 may mirror those of immunocompetent children, with infrequent hospitalization and minimal treatment, if any, required.

Background We describe the successful pediatric liver transplant for unresectable hepatoblastoma in a 4‐year‐old male with COVID‐19 prior to transplant. The first negative nasopharyngeal (NP) swab was documented one month after initial diagnosis, when SARS‐CoV‐2 antibodies were also detected. The patient was actively listed for liver transplant after completing four blocks of a SIOPEL‐4 based regimen due to his PRETEXT IV disease which remained unresectable. Following three additional negative NP swabs and resolution of symptoms for four weeks, he underwent a whole‐organ pediatric liver transplant. Methods COVID‐19 positivity determined via NP swab SARS‐CoV‐2 real‐time RT‐PCR (Hologic Aptima SARS‐CoV‐2 RT‐PCR assay). IgG and IgM total SARS‐ CoV‐2 antibodies detected by Ortho Clinical Diagnostics VITROS® Immunodiagnostics Products Anti‐SARS‐CoV‐2 Test. Results Patient received standard prednisone and tacrolimus‐based immunosuppression without induction therapy following transplant. Post‐transplant course was remarkable for neutropenia and thrombocytopenia, with discharge home on post‐transplant day #11. Surveillance tests have remained negative with persistent SARS‐CoV‐2 IgG antibodies at six weeks after transplant. Conclusions We describe one of the earliest, if not the first case of liver transplant following recent recovery from COVID‐19 in a pediatric patient with a lethal malignant liver tumor. A better understanding of how to balance the risk profile of transplant in the setting of COVID‐19 with disease progression if transplant is not performed is needed. We followed existing ASTS guidelines to document clearance of the viral infection and resolution of symptoms before transplant. This case highlights that pediatric liver transplantation can be safely performed upon clearance of COVID‐19.

In January 2020, we identified two SARS‐CoV‐2 infections in a familial cluster with one person coming from Wuhan, China. The complete genome sequences of two SARS‐CoV‐2 strains isolated from these patients were identical and 99.98% similar to strains isolated in Wuhan. This is genetically suggestive of human‐to‐human transmission of SARS‐CoV‐2 and indicates Wuhan as the most plausible origin of the early outbreak in Vietnam. The younger patient with a mild upper respiratory illness and a brief viral shedding, while the elderly with multi‐morbidity had pneumonia, prolonged viral shedding, and residual lung damage. Evidence of nonsynonymous substitutions in the ORF1ab region of the viral sequence warrants further studies. This article is protected by copyright. All rights reserved.

Fe deficiency (ID) defined as plasma ferritin 10 mg/l, twin birth or prematurity. Associations with ID were analysed by logistic regression, adjusting for sex, maternal education, duration of partial breast-feeding and current intake of milk, fish and meat. Overall, fifty-six children had ID (15·1 %). Factors associated with increased risk were exclusive breast-feeding beyond 4 months (OR 5·97; 95 % CI 1·63, 21·86) and no intake of oral Fe supplements from 6 to 12 months (OR 3·99, 95 % CI 1·33, 11·97. Duration of partial breast-feeding and current diet was not associated with ID. In conclusion, the ID prevalence was 15·1 %, and both exclusive breast-feeding beyond 4 months and no intake of oral Fe supplements from 6 to 12 months were associated with increased risk of ID in 18-month-old children.

Author(s): Wang, Jiayun; Yeh, Thao N; Chakraborty, Rudrasis; Yu, Stella X; Lin, Meng C | Abstract: PurposeTo develop a deep learning approach to digitally segmenting meibomian gland atrophy area and computing percent atrophy in meibography images.MethodsA total of 706 meibography images with corresponding meiboscores were collected and annotated for each one with eyelid and atrophy regions. The dataset was then divided into the development and evaluation sets. The development set was used to train and tune the deep learning model, while the evaluation set was used to evaluate the performance of the model.ResultsFour hundred ninety-seven meibography images were used for training and tuning the deep learning model while the remaining 209 images were used for evaluations. The algorithm achieves 95.6% meiboscore grading accuracy on average, largely outperforming the lead clinical investigator (LCI) by 16.0% and the clinical team by 40.6%. Our algorithm also achieves 97.6% and 95.4% accuracy for eyelid and atrophy segmentations, respectively, as well as 95.5% and 66.7% mean intersection over union accuracies (mean IU), respectively. The average root-mean-square deviation (RMSD) of the percent atrophy prediction is 6.7%.ConclusionsThe proposed deep learning approach can automatically segment the total eyelid and meibomian gland atrophy regions, as well as compute percent atrophy with high accuracy and consistency. This provides quantitative information of the gland atrophy severity based on meibography images.Translational relevanceBased on deep neural networks, the study presents an accurate and consistent gland atrophy evaluation method for meibography images, and may contribute to improved understanding of meibomian gland dysfunction.

Background: Rhabdomyosarcoma originating in the mastoid is rare and may be misdiagnosed as an infectious mastoiditis due to overlapping clinical and imaging features. We aimed to identify distinguishing characteristics to facilitate earlier diagnosis and treatment. Method: Here we describe a case report and a systematic review of 23 reports describing previous cases of mastoid rhabdomyosarcoma. We compare these patients to a systematic review of patients with infectious mastoiditis and identify distinguishing clinical features. Results: A total of 43 patients with rhabdomyosarcoma of the mastoid were identified and compared with patients with mastoiditis. Rhabdomyosarcoma patients were more likely to present with a mass (86%) or cranial nerve dysfunction (83.7%), while mastoiditis patients were more likely to have fever (72.4%), pain (48.2%), and present at a younger age (4.4 vs. 6.1 years). The average lifespan with rhabdomyosarcoma of the mastoid was 7.1 months after diagnosis, with 41.7% of patients alive at the time of report. Conclusions: Based on abstracted and aggregated information, we identified unique features observed more frequently in each of rhabdomyosarcoma and mastoiditis. These predictive features allow for the differentiation of each diagnosis and avoid the delay of proper treatment.

Background Advances in critical care prolong survival in children with liver failure, allowing more critically ill children to undergo orthotopic liver transplantation (OLT). In order to justify the use of a scarce donor resource and avoid futile transplants, we sought to determine survival in children who undergo OLT while receiving pre-OLT critical care. Study Design We analyzed 13,723 pediatric OLTs using the United Network for Organ Sharing (UNOS) database from 1987 to 2015, including 6,746 recipients in the Model for End-Stage Liver Disease/Pediatric End-Stage Liver Disease (MELD/PELD) era (2002 to 2015). There were 1,816 recipients (26.9%) admitted to the ICU at the time of transplantation. We also analyzed 354 pediatric OLT recipients at our center from 2002 to 2015, one of the largest institutional experiences. Sixty-five recipients (18.3%) were admitted to the ICU at the time of transplantation. Kaplan-Meier, volume threshold, and multivariable analyses were performed. Results Patient survival improved steadily over the study period, (66% 1-year survival in 1987 vs 92% in 2015; p Conclusions This analysis demonstrates that the use of advanced critical care in children and infants with liver failure is justified because OLT can be performed on the sickest children and acceptable outcomes achieved. It is an appropriate use of a scarce donor allograft in a child who would otherwise succumb to a terminal liver disease.

OBJECTIVES To compare subjective and clinical outcomes in three study groups: (1) asymptomatic contact lens (CL) wearers (ASYM); (2) symptomatic CL wearers who become asymptomatic on lens removal; and (3) symptomatic CL wearers who do not resolve on lens removal. METHODS Ninety-two subjects completed the Berkeley Dry Eye Flow Chart with and without lenses, ocular surface examinations, and a battery of questionnaires. RESULTS Thirty-seven subjects (40%) were ASYM, 30 (33%) had contact lens-induced dry eye (CLIDE), and 25 (27%) had underlying physiological DE. Visual Analog Scale ratings, OSDI score, and SPEED score were significantly better for the ASYM group (P

Author(s): Yeh, Thao N; Lin, Meng C | Abstract: PurposeMeibomian gland contrast may be a potential indicator of gland health, especially among isotretinoin users. We aimed to develop a repeatable and reliable method for measuring Meibomian gland contrast from meibography images.MethodsLower lid (LL) and upper lid (UL) meibography were captured with the OCULUS Keratograph 5M (OCULUS, Inc) at 2 visits under the following 4 conditions: face centered with room lights on (C), left-turned face (L), right-turned face (R), and face centered with room lights off (CLO). Contrast was measured with Fiji (v2.0.0-rc-59). Coefficient of repeatability and limits of agreement (LOA) were determined using Bland-Altman plots.ResultsA total of 512 meibography images from 16 subjects (age ± SD = 24.8 ± 5.2 years; 13 female patients) were collected. Coefficient of repeatability between visits was 10.5 for UL and 14.9 for LL. Lower and upper LOA, respectively, for UL, compared with condition C, were -10.9 [95% confidence interval (CI), -13.5 to -8.3] and 6.2 (95% CI, 3.6-8.8) for L; -11.0 (95% CI, -13.8 to -8.1) and 7.0 (95% CI, 4.2-9.8) for R; and -9.0 (95% CI, -11.6 to -6.5) and 7.2 (95% CI, 4.7-9.8) for CLO. Lower and upper LOA, respectively, for LL, compared with condition C, were -18.1 (95% CI, -22.6 to -13.5) and 11.0 (95% CI, 6.5-15.5) for L; -15.3 (95% CI, -19.2 to -11.3) and 9.9 (95% CI, 6.0-13.9) for R; and -12.0 (95% CI, -15.1 to -8.8) and 8.2 (95% CI, 5.0-11.3) for CLO.ConclusionsMeibomian gland contrast is a repeatable and reliable measure for changes in Meibomian gland contrast greater than 11 in the UL and 18 in the LL.

Summary:. In the fall of 2017, Hurricane Harvey, one of the most costly hurricanes in American history, ravaged the Texas Gulf Coast, interrupting basic sanitation systems to hundreds of thousands of Texas residents. In the aftermath of Hurricane Harvey, our Houston hospitals noted an uptick in the incidence of cases of mucormycosis. Among the most vulnerable and affected have been immunocompromised transplant recipients. Here, we describe the successful management of 2 patients with atypical presentations of mucormycosis, 2 cutaneous infections after liver transplantation. Our comprehensive treatment strategy based upon guidelines and experience included coordinating aggressive surgical and medical therapies. We discuss our approach to surgical management including the extent and frequency of debridement, the methods of assessing disease-free margins, and minimizing the morbidity of radical debridement with temporary coverage and forethought to long-term reconstruction. Additionally, we describe the concurrent medical management, including type, route, and duration of antifungal therapy, minimizing suppression of the innate immune system, and optimizing the wound healing environment through maintaining nutritional status.

This study aimed to assess the knowledge of antiretroviral (ARV) treatment and the associated factors in HIV-infected patients in Vietnam. We conducted a cross-sectional descriptive study of 350 human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients being treated with ARV at outpatient clinics at Soc Trang, Vietnam, from June 2019 to December 2019. Using an interview questionnaire, patients who answered at least eight out of nine questions correctly, including some required questions, were considered to have a general knowledge of ARV treatment. Using multivariate logistic regression to identify factors associated with knowledge of ARV treatment, we found that 62% of HIV-infected patients had a general knowledge of ARV treatment, with a mean score of 8.2 (SD 1.4) out of 9 correct. A higher education level (p &lt, 0.001), working away from home (p = 0.013), getting HIV transmitted by injecting drugs or from mother-to-child contact (p = 0.023), the presence of tension, anxiety, or stress (p = 0.005), self-reminding to take medication (p = 0.024), and a high self-evaluated adherence (p &lt, 0.001) were found to be significantly associated with an adequate knowledge of ARV treatment. In conclusion, education programs for patients, as well as the quality of medical services and support, should be strengthened.

The initial experience with ABO incompatible (ABOi) orthotopic liver transplantations (OLTs) was dismal. In the current study, we investigated whether ABOi pediatric OLTs could achieve acceptable patient outcomes. The option for ABOi transplantation is vital because critically ill children have limited access to donor liver allografts.Kaplan-Meier and multivariate Cox analysis was performed on data collected from 13,179 pediatric OLT recipients in the United Network for Organ Sharing database, including 540 ABOi recipients. We also analyzed 18 pediatric recipients of ABOi OLTs at Texas Children's Hospital. Recipients were divided into 2 groups: transplanted between 1987 to 2002 (remote era) and 2002 to 2013 (modern era).Analysis revealed 4 main points. First, there was a significant (p0.01) improvement in ABOi OLT survival in the modern era. Second, threshold analysis revealed superior outcomes (p0.01) for OLT recipients younger than 2 years of age. Third, survival outcomes for ABOi and ABO-identical OLTs were the same for recipients younger than 2 years: ABOi was 91.8% (1 year) and 88.4% (5 year), and ABO identical was 91.5% (1 year) and 86.7% (5 year) (p = 0.94). Lastly, we found identical OLT results when analyzing our own institutional experience. To date, there has been a 92.9% survival rate in the modern era compared with 75% in the remote era. All recipients younger than 2 years (n = 9) are still alive, compared with 78% of those older than 2 years.This analysis revealed a significant improvement in the survival of ABOi liver transplant recipients in the modern era. Importantly, ABOi liver transplantation can be performed in recipients younger than 2 years of age with equivalent outcomes compared with ABO-identical recipients.

Children undergoing liver transplantation are at a significant risk for intraoperative hemorrhage and thrombotic complications, we aim to identify novel risk factors for massive intraoperative blood loss and transfusion in PLT recipients and describe its impact on graft survival and hospital LOS. We reviewed all primary PLTs performed at our institution between September 2007 and September 2016. Data are presented as n (%) or median (interquartile range). EBL was standardized by weight. Massive EBL and MT were defined as greater than the 85th percentile of the cohort. 250 transplantations were performed during the study period. 38 (15%) recipients had massive EBL, and LOS was 31.5 (15-58) days compared to 11 (7-21) days among those without massive EBL (P < 0.001). MT median LOS was 34 (14-59) days compared to 11 (7-21) days among those without MT (P = 0.001). Upon backward stepwise regression, technical variant graft, operative time, and transfusion of FFP, platelet, and/or cryoprecipitate were significant independent risk factors for massive EBL and MT, while admission from home was a protective factor. Recipient weight was a significant independent risk factor for MT alone. Massive EBL and MT were not statistically significant for overall graft survival. MT was, however, a significant risk factor for 30-day graft loss. PLT recipients with massive EBL or MT had significantly longer LOS and increased 30-day graft loss in patients who required MT. We identified longer operative time and technical variant graft were significant independent risk factors for massive EBL and MT, while being admitted from home was a protective factor.

Purpose:There has been interest in determining whether lid wiper epitheliopathy (LWE) plays a key role in causing ocular discomfort. Conflicting reports have made it difficult to discern whether LWE is more prevalent in certain populations, what characteristics are associated with its severity, and what its role is in symptomology. This cross-sectional study on a large and diverse population attempts to answer these questions. Methods:Subjects were asked to complete questionnaires related to dry eye and to ocular discomfort. A comprehensive set of ocular surface parameters were assessed, including LWE length and width, tear-film lipid layer thickness, fluorescein tear breakup time (FTBUT), lid-parallel conjunctival folds (LIPCOF), and corneal staining. Results:A total of 287 subjects participated in the study. LWE was observed in 45% of the study cohort and was twice as prevalent in Asians than non-Asians (P < 0.005). LWE was more likely to present in contact lens wearers than non-contact lens wearers (P = 0.03). Decreased FTBUT was associated with increased LWE length and width (P < 0.005 and P = 0.01, respectively), although only a small effect size was noted. Presence of LIPCOF was linked with a 0.25-grade increase in LWE width (P = 0.01). Only LWE width was associated with greater symptoms in contact lens wearers. Conclusions:LWE was associated with decreased tear-film stability, contact lens wear, lid anatomy, and LIPCOF. LWE was not associated with symptoms in non-contact lens wearers. LWE width was associated with greater symptoms in contact lens wearers but was only clinically significant with moderate to severe LWE width.

An index that predicts liver allograft discard can effectively grade allografts and can be used to preferentially allocate marginal allografts to aggressive centers. The aim of this study is to devise an index to predict liver allograft discard using only risk factors available at the time of initial DonorNet offer.Using univariate and multivariate analyses on a training set of 72 297 deceased donors, we identified independent risk factors for liver allograft discard. Multiple imputation was used to account for missing variables.We identified 15 factors as significant predictors of liver allograft discard; the most significant risk factors were: total bilirubin10 mg/dL (odds ratio [OR], 25.23; confidence interval [CI], 17.32-36.77), donation after circulatory death (OR, 14.13; CI, 13.30-15.01), and total bilirubin 5 to 10 mg/dL (OR, 7.57; 95% CI, 6.32-9.05). The resulting Discard Risk Index (DSRI) accurately predicted the risk of liver discard with a C statistic of 0.80. We internally validated the model with a validation set of 37 243 deceased donors and also achieved a 0.80 C statistic. At a DSRI at the 90th percentile, the discard rate was 50% (OR, 32.34; CI, 28.63-36.53), whereas at a DSRI at 10th percentile, only 3% of livers were discarded.The use of the DSRI can help predict liver allograft discard. The DSRI can be used to effectively grade allografts and preferentially allocate marginal allografts to aggressive centers to maximize the donor yield and expedite allocation.

Stress-induced heart failure, also known as Broken Heart Syndrome or Takotsubo Syndrome, is a phenomenon characterized as rare but well described in the literature, with increasing incidence. While more commonly associated with postmenopausal women with psychiatric disorders, this entity is found in the postoperative patient. The nonischemic cardiogenic shock manifests as biventricular failure with significant decreases in ejection fraction and cardiac function. In a review of over 3000 kidney and liver transplantations over the course of 17 years within two transplant centers, we describe a series of 7 patients with Takotsubo Syndrome after solid organ transplantation. Furthermore, we describe a novel approach of successfully treating the transient, though potentially fatal, cardiogenic shock with a percutaneous ventricular assistance device in two liver transplant patients, while treating one kidney transplant patient medically and the remaining four liver transplant patients with an intra-aortic balloon pump. We describe our experience with Takotsubo’s Syndrome and compare the three modalities of treatment and cardiac augmentation. Our series is novel in introducing the percutaneous ventricular assist device as a more minimally invasive intervention in treating nonischemic heart failure in the solid organ transplant patient, while serving as a comprehensive overview of treatment modalities for stress-induced heart failure.

Histoplasmosis is an endemic mycosis in the Ohio and Mississippi River valleys and can cause disseminated infection in immunocompromised hosts. Disseminated histoplasmosis is often respiratory in nature and most cases in transplant patients occur within 2 years post-transplantation. A 32-year-old male on mycophenolate and tacrolimus who underwent an orthotopic liver transplantation 10 years prior presented with generalized body aches, fevers, mild congestion, dysuria and elevated transaminases. Liver biopsy revealed epithelioid granulomas with narrow-based budding yeast, suggesting histoplasma. Liver involvement in disseminated histoplasmosis is well characterized however the disease is usually pulmonary in origin. Only three other case reports describe isolated granulomatous hepatitis, and this is the first to our knowledge to occur in a liver transplant allograft. A high index of suspicion is essential for diagnosis and prompt treatment of histoplasmosis in transplant patients considering their immunocompromised state.

Risk analysis of cold ischemia time (CIT) in liver transplantation has largely focused on patient and graft survival. Posttransplant length of stay is a sensitive marker of morbidity and cost. We hypothesize that CIT is a risk factor for posttransplant prolonged length of stay (PLOS) and aim to conduct an hour-by-hour analysis of CIT and PLOS. We retrospectively reviewed all adult, first-time liver transplants between March 2002 and September 2016 in the United Network for Organ Sharing database. The 67,426 recipients were categorized by hourly CIT increments. Multivariate logistic regression of PLOS (defined as >30 days), CIT groups, and an extensive list of confounding variables was performed. Linear regression between length of stay and CIT as continuous variables was also performed. CIT 1-6 hours was protective against PLOS, whereas CIT >7 hours was associated with increased odds for PLOS. The lowest odds for PLOS were observed with 1-2 hours (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.45-0.92) and 2-3 hours (OR, 0.65; 95% CI, 0.55-0.78) of CIT. OR for PLOS steadily increased with increasing CIT, reaching the greatest odds for PLOS with 13-14 hours (OR, 2.05; 95% CI, 1.57-2.67) and 15-16 hours (OR, 2.06; 95% CI, 1.27-3.33) of CIT. Linear regression revealed a positive correlation between length of stay and CIT with a correlation coefficient of +0.35 (P < 0.001). In conclusion, post-liver transplant length of stay is sensitive to CIT, with a substantial increase in the odds of PLOS observed with nearly every additional hour of cold ischemia. We conclude that CIT should be minimized to protect against the morbidity and cost associated with posttransplant PLOS. Liver Transplantation 24 762-768 2018 AASLD.

As many health disparities in American minority communities (AMCs) are stress-related, there has been an increased interest in the development of mindfulness programs as potential stress reduction measures in these communities. However, the bulk of the extant literature on mindfulness research and mindfulness interventions is based upon experiences with the larger White community. The intent of this commentary is to share a framework that includes key cultural considerations for conducting research and developing culturally-salient mindfulness programs with AMCs. We build on our experiences and the experiences of other researchers who have explored mindfulness in African and Native American communities; in particular, we examine issues around community outreach with an emphatic gesture toward emphasizing protection of AMCs and their participants. Discussed are considerations with respect to attitudinal foundations in mindfulness-based research and program development with these communities. However, the overall message of this paper is not to provide a "to-do" list of research steps, but to rather, encourage researchers to turn inward and consider the development of skillful characteristics that will increase the likelihood of a successful research venture while also protecting the cultural traditions of the AMC of interest.

Mesenchymal liver hamartomas are benign tumors that can cause life-threatening abdominal distension and carry a risk for malignant transformation. In this case report, we describe a 13-month-old male with Beckwith–Wiedemann Syndrome (BWS) who presented with multiple mesenchymal liver hamartomas causing severe intra-abdominal mass effect. Imaging revealed six large multi-locular cystic lesions, ranging from 3.8 to 8.9 cm in diameter. The large size and spread of the tumors necessitated liver transplantation for complete removal. The patient successfully underwent cadaveric piggyback liver transplantation at 25 months of age. He was alive at 16-month follow-up without evidence of tumor recurrence or graft rejection. Histological examination of the hepatic masses revealed mucinous epithelial lining and abundant hepatocytes in varying stages of differentiation, supporting the diagnosis of mesenchymal hamartoma. To the best of our knowledge, this is the first reported case of liver transplantation in a patient with BWS as definitive treatment for unresectable mesenchymal liver hamartoma.

The primary aim of this prospective study is to develop and validate a new prognostic model for predicting the risk of mortality in Emergency Department (ED) patients. The study involved 1765 patients in the development cohort and 1728 in the validation cohort. The main outcome was mortality up to 30 days after admission. Potential risk factors included clinical characteristics, vital signs, and routine haematological and biochemistry tests. The Bayesian Model Averaging method within the Cox’s regression model was used to identify independent risk factors for mortality. In the development cohort, the incidence of 30-day mortality was 9.8%, and the following factors were associated with a greater risk of mortality: male gender, increased respiratory rate and serum urea, decreased peripheral oxygen saturation and serum albumin, lower Glasgow Coma Score, and admission to intensive care unit. The area under the receiver operating characteristic curve for the model with the listed factors was 0.871 (95% CI, 0.844–0.898) in the development cohort and 0.783 (95% CI, 0.743–0.823) in the validation cohort. Calibration analysis found a close agreement between predicted and observed mortality risk. We conclude that the risk of mortality among ED patients could be accurately predicted by using common clinical signs and biochemical tests.

Purpose Assess potential risk factors for severe Meibomian gland atrophy (SMGA) in a young adult population. Methods Cross-sectional study using medical history and ocular surface examination to evaluate relationships with study outcomes: SMGA, tear lipid layer (TLL) thickness, non-invasive (NITBUT) and fluorescein (FTBUT) tear breakup times, and symptoms using the Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire. Results One hundred one participants (101; 202 eyes; Age: mean±SD = 22.3±4.0 years) completed the study. Hormonal birth control (HBC) use was the only significant risk factor for SMGA (p = 0.028). Female HBC users had 4.8 times greater odds of having SMGA compared to female HBC non-users (p = 0.028), but the odds of having SMGA was similar between female HBC non-users and males (p = 0.885). Multivariable analysis suggested that the relationship between SMGA and TLL thickness was dependent on HBC use. Compared to female HBC non-users without SMGA, TLL thickness for HBC users was estimated to be 10 nm thinner if SMGA was absent (p = 0.007) and 21 nm thinner if SMGA was present (p

Careful management of immunosuppression is paramount to prevent acute rejection in kidney transplantation. We studied a cohort of 139,875 kidney transplant recipients from the Organ Procurement and Transplantation Network (OPTN) database between 2002 and 2013. We confirmed the analysis with a cohort of 35,277 who received thymoglobulin induction with tacrolimus maintenance, and a third cohort of 12,161 recipients who received basiliximab induction with tacrolimus maintenance. We performed multivariate logistic regression analyses on data from all three cohorts and identified independent risk factors for treated acute rejection at 1 year. Recipient age was a robust risk factor for rejection in all three cohorts in a dose response pattern. Young age (18-25 years) was among the strongest risk factors for rejection in all three cohorts; thymoglobulin cohort: OR 1.87 (1.59-2.19); basiliximab cohort: OR 2.41 (1.89-3.05); and inclusive cohort: OR 1.97 (1.83-2.12). The opposite was true for old age (65-69 years); thymoglobulin cohort: OR 0.69 (0.59-0.81); basiliximab cohort: OR 0.77 (0.62-0.96); and inclusive cohort: OR 0.75 (0.70-0.80). This study is unique because it is the largest and most comprehensive multivariate analysis that demonstrates recipient age is a robust risk factor for acute rejection in an inverse dose response pattern.

Background Careful management of induction and maintenance of immunosuppression is paramount to prevent acute rejection in liver transplantation. A methodical analysis of risk factors for acute cellular rejection may provide a more comprehensive method to profile the immunologic risk of candidates. Methods Using registry data from the Organ Procurement and Transplantation Network (OPTN), we identified 42,508 adult recipients who underwent orthotopic liver transplant (OLT) between 2002 and 2013. We excluded recipients with a blank entry for treated rejection. We analyzed this all inclusive cohort in addition to a subset of 27,493 patients with just tacrolimus immunosuppression. Multivariate logistic regression was used on both cohorts and identified independent risk factors for treated acute rejection at one year. Results Recipient age (reference group was 40 to 60 years) was a dominant risk factor for rejection in both cohorts and had a dose response relationship. The strongest risk factors in the inclusive cohort were: age 18–25 (OR 2.20), age 26–29 (OR 2.03), and primary biliary cholangitis (OR 1.55). The most protective factors were age 70 and older (OR 0.68), and age 65–69 (OR 0.70). The rates of rejection had a similar pattern. Conclusions Although prior studies have suggested age as a risk factor for rejection in liver transplantation, this is the first study of national-level data to demonstrate a robust dose dependent relationship between age and risk for rejection at one year. Clinicians should place significant weight on recipient age when they assess their recipients for the immunologic risk of rejection.

Many community mobilization activities for youth violence prevention involve the researchers assisting communities in identifying, adapting, and/or tailoring evidence-based programs to fit the community needs, population, and cultural and social contexts. This article describes a slightly different framework in which the collaborative research/evaluation project emerged from the community mobilization activities. As will be discussed, this collaborative, sustained partnership was possible in the context of the Center on Culture, Immigration and Youth Violence Prevention's (UC Berkeley ACE) community mobilization activities that brought the issue of youth violence, particularly among immigrant and minority populations, to the forefront of many of the community partners' agendas. The East Bay Asian Youth Center (EBAYC) was one of the partners that came to the table, which facilitated the community-based engagement/mobilization. UC Berkeley ACE collaborated with EBAYC to evaluate an after-school program and an alternative probation program serving a diverse youth and immigrant population, including African Americans, Asians, and Hispanics. This article describes UC Berkeley ACE's community mobilization activity and the collaborative partnership with EBAYC, discusses how the evaluations incorporated community-based principles in design and practice, and presents some findings from the evaluations.

Background Mucinous, medullary, and tubular carcinomas are uncommon types of breast cancer whose rarity does not permit large single-institution studies or randomized trials to define optimal treatments. In this study, we evaluated the long-term outcomes of breast-conserving therapy (BCT) for these subtypes of breast cancer and compared them with those for invasive ductal carcinoma. Methods In our institutional database of patients who received BCT from 1965 to 1999, 1,643 patients with stage I to II mucinous (61), medullary (37), tubular (60), and invasive ductal (1,485) histologies were identified. The clinical and pathologic features of the 4 groups were evaluated and compared with respect to local-regional recurrence rates, disease-free survival, and overall survival (OS). Results No statistically significant differences were found in the local-regional failure rate among the 4 groups (10.6-year median follow-up). Only patients with tubular carcinoma had better 5- and 10-year OS rates ( P = .013). In multivariable analysis, factors associated with improved OS included age at or below 50 years, negative nodal status, use of chemotherapy or hormonal therapy, and tubular histology. Conclusions BCT for mucinous, medullary, or tubular carcinoma resulted in similar local-regional failure rates to that for invasive ductal carcinoma. Tubular carcinoma patients had the most favorable OS. BCT is an appropriate treatment strategy for early-stage mucinous, medullary, and tubular carcinomas.

Tear hyperosmolarity and tear film instability are key factors in the development of dry eye (DE) disease.1 Low aqueous flow (aqueous-deficient DE) or high aqueous evaporation (evaporative DE) can both lead to tear hyperosmolarity, which is associated with many pathophysiological changes. Experimentally induced “dry eye,” with its attendant tear hyperosmolarity, has been shown to stimulate ocular surface inflammation through increased expression and production of proinflammatory cytokines and chemokines in the tears2–6 and to result in corneal epithelial cell death by apoptosis.7 Ocular surface disease and tear hyperosmolarity have also been associated with goblet cell loss,8,9 which can lead to altered mucin expression10 and tear film instability.8,11 Ocular surface cooling attributed to aqueous evaporation, which has also been associated with tear hyperosmolarity, may stimulate sensory nerve fibers innervating the ocular surface, including polymodal nociceptors, mechanonociceptors, or cold thermoreceptors, and generate sensations of ocular discomfort.12,13 Although tear osmolarity has gained widespread acceptance as a diagnostic for DE disease,14–23 recent findings suggest that tear osmolarity measurements do not possess the very high sensitivity and specificity claimed by some studies15,24 and that it may have limited value in the diagnosis of DE.25 Similarly, although tear film instability has been linked to symptoms of dryness and discomfort in several studies,16,26–30 other studies have found contradictory evidence.14,15,31–33 Even among tear film stability assessments, it is not clear how well correlated are noninvasive and invasive (i.e., using sodium fluorescein dye) tear breakup times (TBUTs), or whether the two methods are even assessing the same type or aspect of tear breakup.27,29,32,34,35 Additionally, information on the relationship between tear osmolarity and tear film stability is emerging, with some studies reaching opposing conclusions.11,15,19,24,36–40 Clearly, there is a lack of consensus on many facets of the relationships among tear osmolarity, tear film stability, and dryness symptoms.41,42 This study proposes to provide additional evidence by (1) examining the relationships among tear osmolarity, TBUT (noninvasive and with fluorescein), and dryness symptoms measured using both subjective symptom rating scale questionnaires and a previously published categorical classification tool43 and (2) determining whether these relationships differ with subject demographic characteristics or contact lens (CL) use. Our goal is to gain further understanding of the complex interrelationships among common clinical and subjective assessments used in the diagnosis and treatment of DE disease.

This chapter addresses the logistics of establishing clinical videoconferencing (CV) programs and denotes commonly unforeseen barriers to implementation. The authors provide recommendations on central issues related to successful programing: where clients will be served, relationships with partner clinics, identifying program services, reviewing laws and policies, secure communication with patients, transitional programming, and recruiting clinicians.

The purpose of this study was to investigate infant oral mutans streptococci (MS) by feeding method and by the mother's oral MS status. For this cross-sectional data collection, full-term infants at 4-6 weeks of age and their mothers were tested for oral MS using the Dentocult(®) SM chairside test (Orion Diagnostica, Espoo, Finland). For the 104 mother-infant pairs (68 breastfed, 36 formula-fed), the two groups differed by mother's race/ethnicity (p=0.006) but not by delivery mode, level of care at birth, or MS in the mothers or the infants. Thirty-one percent of mothers and 12% of infants were MS positive. Infant MS was not predicted by mother's race/ethnicity, delivery mode, feeding method, or MS status. When stratified by feeding method, the mother's MS status did significantly predict the infant's MS status in the breastfed group (odds ratio=5.97; 95% confidence interval, 1.06-33.7; p=0.043). In conclusion, oral MS at10(4) colony-forming units/mL were detected in 12% of the 4-6-week-old infants, and the effect of the mothers' oral MS status was modified by the feeding method. Future research is needed to clarify the modifiable perinatal and maternal risks associated with the development of the infant's predentate oral microbial environment, before the introduction of the first tooth.

Drowning, a common cause of death in the pediatric population, is a potentially large donor pool for OLT. Anecdotally, transplant centers have deemed these organs high risk over concerns for infection and graft dysfunction. We theorized drowned donor liver allografts do not portend worse outcomes and therefore should not be excluded from the donation pool. We reviewed our single-center experience of pediatric OLTs between 1988 and 2015 and identified 33 drowned donor recipients. These OLTs were matched 1:2 to head trauma donor OLTs from our center. A chart review assessed postoperative peak AST and ALT, incidence of HAT, graft and recipient survival. Recipient survival at one year between patients with drowned donor vs head trauma donor allografts was not statistically significant (94% vs 97%, P=.63). HAT incidence was 6.1% in the drowned donor group vs 7.6% in the control group (P=.78). Mean postoperative peak AST and ALT was 683 U/L and 450 U/L for drowned donors vs 1119 U/L and 828 U/L in the matched cohort. These results suggest drowned donor liver allografts do not portend worse outcomes in comparison with those procured from head trauma donors.

Portosystemic shunts can serve as a bridge to liver transplantation in patients with end-stage liver disease by providing portal decompression to treat life-threatening variceal bleeding and prevent recurrent episodes until an organ becomes available. The conventional TIPS procedure, however, is technically challenging to perform in infants due to the small size of their intrahepatic vasculature. We report two cases of emergent creation of portosystemic shunts as a bridge to liver transplantation in infants with life-threatening variceal bleeding using a conventional TIPS technique in the first case and a percutaneous DIPS technique in the other. Both procedures were successful at reducing the portosystemic pressure gradient and preventing further variceal bleeds until a liver transplant could be performed. The novel percutaneous DIPS procedure is a valuable alternative to the conventional TIPS in infants, as it is better suited for small or challenging intrahepatic vascular anatomy.
