Background This study assessed associations between processed electroencephalographic (pEEG) use during anesthesia, surgery- and anesthesia-related risk factors, and neurologic outcomes and mortality after cardiac surgery. Methods Drawing from the Society of Thoracic Surgeons Adult Cardiac Surgery Database and its Adult Cardiac Anesthesiology Section, we identified 42,932 records for elective, urgent, and emergency cardiac surgery procedures between July 1, 2017, to December 31, 2019. Using propensity score weighted regression analysis, we analyzed the associations between pEEG use during anesthesia on the primary outcome, postoperative delirium (POD), and secondary outcomes (stroke, encephalopathy, coma, and operative mortality). Results The rate of pEEG use during anesthesia use was 32.8% (n=14,086), and its use was not associated with decreased odds for POD (odds ratio [OR], 0.88; 95%CI, 0.78-1.02) or encephalopathy (OR, 0.85; 95%CI, 0.70-1.03). Intraoperative pEEG monitoring use was also not associated with increased odds for stroke (OR, 1.17; 95%CI, 0.97-1.42) or coma (OR, 1.44; 95%CI, 0.82-2.52). In contrast, pEEG use during anesthesia was associated with higher odds for operative mortality (OR, 1.23; 95%CI, 1.05-1.44). This association remained significant after adjusting for POD (OR: 1.21, 95%CI: 1.03-1.41), stroke (OR: 1.21, 95%CI:1.04-1.42), and encephalopathy (OR: 1.28, 95%CI: 1.07-1.52). Conclusions This large retrospective database study found no association between pEEG use during cardiac surgery and postoperative neurologic outcomes such as POD, stroke, encephalopathy, or coma. However, patients who underwent pEEG monitoring during anesthesia experienced higher mortality, even after adjustment for neurologic outcomes.

Objectives: This study aimed to determine the pattern of clinical presentations associated with Chlamydia trachomatis and Neisseria gonorrhoeae infections. Methods: A retrospective cohort study was conducted between 2015 and 2020 and included patients attending Sultan Qaboos University Hospital, Muscat, Oman, who were tested for these infections using nucleic acid amplification. Results: A total of 408 women and 89 men were included. A total of 11 infections were identified in women (n = 11, 2.7%) and 14 in men (n = 14, 15.7%). Chlamydia accounted for almost all infections in women (n = 10, 90.9%), commonly presenting with lower abdominal pain or abnormal vaginal bleeding. In men, urethral discharge/dysuria syndrome was the most common presentation and chlamydia was identified in eight men and gonorrhoea in six; a majority of all infections were seen in patients ≤35 years old. Conclusion: The relative prevalence of two common sexually transmitted infections (STIs) among patients with genitourinary symptoms at a tertiary referral hospital have been described. The pattern of their presentations will inform the design of prospective studies to improve surveillance and guide public health policy in Oman. This study highlights the need for a multi-sectoral approach involving all providers to enable comprehensive STI surveillance.

Pulmonary venous thrombosis (PVT) is a rare but potentially devastating disease state with a largely unknown incidence. The most common etiologies of PVT are secondary to complications of lung surgery, malignancy, catheter ablation for atrial fibrillation, and idiopathic causes. Diagnosis can be challenging because presenting symptoms often are vague and nonspecific, or even asymptomatic, and traditional diagnostic modalities, such as chest radiography and arterial phase computed tomography scans, are poor techniques for diagnosis. The authors present a case of a patient presenting for pulmonary thromboendarterectomy for a presumed diagnosis of chronic thromboembolic pulmonary hypertension who was found incidentally to have a PVT, on intraoperative transesophageal echocardiography. Due to significant thrombus burden, the new finding of PVT, and known association of PVT and malignancy, a biopsy of mediastinal lymph nodes was obtained, which revealed metastatic cervical carcinoma. The pulmonary endarterectomy procedure was aborted.

( limit 350 words) Objective To determine which patient reported symptoms best distinguishes patients with and without glaucoma and explains the most variance in visual field (VF) damage, and compare the amount of variance that can be explained by symptoms vs. retinal nerve fiber layer (RNFL) thickness. Design Cross-sectional study. Participants Adults diagnosed with glaucoma or suspicion of glaucoma (controls). Methods Worse-eye VF damage was defined based on perimetric testing. RNFL thickness was defined by OCT imaging. Patients rated their visual symptoms on questions collated from several published questionnaires, rating the frequency and severity of 28 symptoms on a scale of 1 (never/not at all) to 4 (very often/severe). Multivariable regression models identified patient reported symptoms that contributed the highest variance in VF damage. Main Outcome Measures Patient reported symptoms that explained the most variance in VF damage; amount of variance in VF damage explained by patient reported symptoms and RNFL Results A total of 170 patients (mean age= 64; 58% female; 47% employed) completed testing, including 95 glaucoma suspects and 75 glaucoma patients. In glaucoma patients, median mean deviation of VF damage in the worse eye was -19.3 and ranged from -5.3 to -34.7 dB. Symptoms more common amongst glaucoma patients compared to glaucoma suspects included better vision in one eye, blurry vision, glare, sensitivity to light, cloudy vision, and little peripheral vision. Worse severity ratings for the symptom ‘little peripheral vision’ explained the most variance in VF damage (43%). A multivariable model including the frequency of cloudy vision, severity of having little peripheral vision, missing patches, one eye having better vision, and vision worsening, plus sociodemographic features explained 62% of the variance in VF damage. Comparatively, a multivariable model of worse-eye RNFL thickness and sociodemographic features explained 42% of the variance in VF damage, while a model including only sociodemographic features explained 8% of the variance in VF damage. Conclusions Five patient reported symptoms explain a significant amount of the variance in VF damage. Asking patients about their symptoms may optimize patient-physician communication and be a useful adjunct to clinical testing in some patients to estimate disease severity.

For the more than 40,000 children in the United States undergoing congenital heart surgery annually, the relationship between hospital quality and costs remains unclear. Prior studies report conflicting results and clinical outcomes have continued to improve over time. We examined a large contemporary cohort, aiming to better inform ongoing initiatives seeking to optimize health care value in this population.Clinical information (The Society of Thoracic Surgeons Congenital Database) was merged with standardized cost data (Pediatric Health Information Systems) for children undergoing heart surgery from 2010 to 2015. In-hospital cost variability was analyzed using Bayesian hierarchical models adjusted for case-mix. Quality metrics examined included in-hospital mortality, postoperative complications, postoperative length of stay (PLOS), and a composite.Overall, 32 hospitals (n = 45,315 patients) were included. Median adjusted cost per case varied across hospitals from $67,700 to $51,200 in the high vs low cost tertile (ratio 1.32; 95% credible interval, 1.29 to 1.35), and all quality metrics also varied across hospitals. Across cost tertiles, there were no significant differences in the quality metrics examined, with the exception of PLOS. The PLOS findings were driven by high-risk The Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery categories 4 and 5 cases (adjusted median length of stay 16.8 vs 14.9 days in high vs low cost tertile [ratio 1.13, 1.05 to 1.24]), and intensive care unit PLOS.Contemporary congenital heart surgery costs vary across hospitals but were not associated with most quality metrics examined, highlighting that performance in one area does not necessarily convey to others. Cost variability was associated with PLOS, particularly related to intensive care unit PLOS and high-risk cases. Care processes influencing PLOS may provide targets for value-based initiatives in this population.

Barriers to implementing infection prevention and control (IPC) practices may be experienced by healthcare workers (HCWs) caring for people with CF (PwCF), PwCF, and their families. We hypothesized that these stakeholders from CF centers with early adoption of the updated 2013 IPC guideline would experience fewer barriers implementing selected recommendations compared to stakeholders from CF centers with delayed adoption.In 2018-2019 we surveyed HCWs and PwCF/parents from 25 CF centers to identify knowledge, attitude, and practice barriers. Each center recruited five HCWs with different occupations. Pediatric centers recruited five parents of children18 years old and five young adults 18-21 years old. Adult centers recruited 10 adults ≥18 years old. We determined respondents' knowledge scores, the proportion who agreed with or perceived health benefits from recommendations, and reported adherence to recommendations.Knowledge scores, perception of health benefits, and adherence to selected practices were similar among participants from centers with early vs. delayed adoption, yet generally lower for inpatient nurses. IPC practitioners were less likely to perceive health benefits from PwCF wearing masks and HCWs wearing gowns and gloves. Among HCWs, 57% educated75% of PwCF/parents about IPC and 43% advised75% of PwCF/parents to avoid socializing with other PwCF. Among PwCF/parents, 69%, 53%, and 56% reported discussions with their care teams about performing hand hygiene, avoiding socialization, or the 2013 IPC guideline, respectively.Our findings suggest opportunities for targeted education for specific HCW occupations and for PwCF and their families.

Background Inconsistencies in definitions of endodontic outcome terminology jeopardize evaluations of proposed interventions and patient care quality. This scoping review aims to provide groundwork to develop a set of basic outcomes in endodontics. Design A comprehensive literature search for randomized controlled trials, cohort, case-control studies, or case series (≥10 patients) published after 1980 with patients aged≥10 years with any preoperative pulpal and periapical diagnosis in permanent teeth requiring non-surgical root canal treatment, retreatment, or apexification. Abstracted data on outcome assessment methods, assessors, and domains were reported after univariate and bivariate analyses. Results Treatment outcomes were evaluated radiographically (88%) or clinically (73%). While 2-dimensional radiography exceeded 3-dimensional radiography, use of the latter has increased since 2010, mostly for non-surgical retreatments. Of 19 identified outcomes, 5 were most frequent: Success (168 studies, 40%), Radiographic Healing (128 studies, 30%), Survival [of an asymptomatic tooth (48 studies, 12%), or of a procedure code in administrative databases (31 studies, 7%)], Pain Assessment (14 studies, 3%), and Quality of Life (11 studies, 3%). Clinician-centered outcomes have been most frequently studied since the 1980s (71%), in academic settings (76%), using prospective design (45%). Patient-centered outcomes were reported in 19% of studies prior to 2010 and 30% since 2010. They were more common among retrospective studies (49%). Conclusions Patient-centered outcome measures are lacking in endodontic studies. The state of available research can provide a baseline for development of a core outcome set in endodontics, which should represent the important patient-centered outcomes in conjunction with well validated clinician-centered outcomes.

The degree of symptomatic disease and functional burden has been demonstrated to influence patient results and satisfaction in total hip and knee arthroplasty. Although the relationship between preoperative diagnosis and patient outcomes has been an area of study for reverse total shoulder arthroplasty (RTSA), the influence of the progression of cuff tear arthropathy (CTA) has not yet been examined. The purpose of this study was to evaluate whether preoperative radiographic disease burden and scapular geometry impact patient outcomes and satisfaction in a cohort of patients with CTA treated with RTSA.Eighty-six patients were treated for CTA with RTSA performed by the senior author (B.G.) between September 2016 and September 2018 and were enrolled in an institutional registry. At the time of initial evaluation, the baseline American Shoulder and Elbow Surgeons (ASES) score, patient demographic characteristics, history of shoulder surgery, and presence of pseudoparalysis were collected. Radiographs were obtained to evaluate the critical shoulder angle, acromial index, and progression of CTA as assessed by Hamada grading and the Seebauer classification. Patients were contacted to reassess the ASES score and their satisfaction with the improvement in their shoulder function.A total of 79 patients (91.6%) were available for evaluation at a minimum of 24 months of follow-up. Multivariate logistic regression modeling revealed that scapular geometry measurements (critical shoulder angle and acromial index) and the degree of CTA (Seebauer and Hamada classifications) were not associated with worse outcomes as assessed by the ASES score. However, degenerative changes as assessed by the Hamada grade (odds ratio, 0.13 [95% confidence interval, 0.02-0.86]; P = .03) and preoperative ASES score (odds ratio, 1.04 [95% confidence interval, 1.01-1.07]; P = .008) were independently associated with higher satisfaction at 24 months of follow-up.The results indicate that patients with greater CTA disease progression did not show differing outcomes after RTSA compared with patients with milder disease. In contrast, both poorer preoperative function and degenerative changes as assessed by the Hamada classification were associated with greater satisfaction after RTSA for CTA. Given the broad spectrum of disease in CTA, there is likely a corresponding range in patient expectations that requires further study to maximize patient satisfaction.

BACKGROUND Study groups are multicenter collaborations aimed at improving orthopaedic decision-making through higher-powered, more generalizable studies. New research is disseminated through peer-reviewed literature and academic meetings, including the Pediatric Orthopaedic Society of North America (POSNA) annual meeting, which brings together academic and medical professionals in pediatric orthopaedics. The goal of this study was to identify patterns in podium presentations (PP) at the POSNA annual meeting resulting from multicenter study groups during a 15-year period. METHODS A total of 2065 PP from the 2006 to 2020 POSNA annual meetings were identified. The abstracts of each PP were reviewed to determine if they resulted from a multicenter study group and for characteristics including subspecialty focus. PP from 2006 to 2018 were further reviewed for publication in academic journals. Pearson correlation was used to assess change in the number of PP resulting from study groups overtime. Univariate analysis was used to compare characteristics of PP based on study group involvement (significance P

The data on the congenital hyperinsulinism (CHI) in Asian Indian patients is limited. Diazoxide is often unavailable in India, which poses challenge in managing CHI. The study was aimed to present our experience with CHI with a special focus on the effectiveness and cost-effectiveness of octreotide long-acting release (OCT-LAR) among diazoxide-responsive CHI. The data of 14 index cases with CHI registered at our center were retrospectively analyzed. The diagnosis of CHI was based on elevated serum insulin (3.4–32.5 μIU/ml) and C-peptide (0.58–1.98 ng/ml) at the time of symptomatic hypoglycemia (BG≤41 mg/dl). Fourteen patients (13 males) presented at a median (range) age of 3 (1–270) days, seizures being the most common mode of presentation (78.6%). Ten patients were diazoxide-responsive, two were partially responsive, while two were unresponsive. Genetics was available for eight patients; ABCC8 (n=3, 1 novel) and HADH (n=2, both novel) were the most commonly mutated genes. OCT-LAR was offered to eight patients including four with diazoxide-responsive disease and was universally effective. We propose a cost-effective approach to use OCT-LAR in the management of CHI, which may also make it more cost-effective than diazoxide for diazoxide-responsive disease. Five of the 11 (45.5%) patients had evidence of neurological impairment; notably, two patients with HADH mutations had intellectual disability despite diazoxide-responsiveness. We report three novel mutations in CHI-associated genes. We demonstrate the effectiveness of and propose a cost-effective approach to use OCT-LAR in diazoxide-responsive CHI. Mutations in HADH may be associated with abnormal neurodevelopmental outcomes despite diazoxide-responsiveness.

BACKGROUND South Asian Americans experience disproportionately high burden of cardiovascular diseases. Estimating predicted heart failure (HF) risk distribution may facilitate targeted prevention. We estimated the distribution of 10-year predicted risk of incident HF in South Asian Americans and evaluated the associations with social determinants of health and clinical risk factors. METHODS AND RESULTS In the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study, we calculated 10-year predicted HF risk using the Pooled Cohort Equations to Prevent Heart Failure multivariable model. Distributions of low (

Background Given the shortage of suitable donor hearts for cardiac transplantation and the growing interest in donation after circulatory death (DCD), our institution recently began procuring cardiac allografts from DCD donors. Methods Between October 2020 and March 2021, 15 patients with heart failure underwent cardiac transplantation using DCD allografts. Allografts were procured using a modified extracorporeal membrane oxygenation circuit for thoracic normothermic regional perfusion (TA-NRP) and were subsequently transported using cold static storage. Data collection and analysis were performed with institutional review board approval. Results The mean age of the DCD donors was 23 ± 7 years and average time on TA-NRP was 56 ± 8 minutes. Total ischemic time was 183 ± 31 minutes and distance from transplant center was 373 ± 203 nautical miles. Recipient age was 55 ± 14 years, with 8 (55.3%) recipients on durable left ventricular assist device support. Post-transplant, 6 (40%) recipients experienced mild left ventricle primary graft dysfunction (PGD-LV), 3 (20%) recipients experienced moderate PGD-LV, and no recipients experienced severe PGD-LV. Postoperative transthoracic echocardiogram demonstrated left ventricular ejection fraction >55% in all recipients. One recipient (6.6%) developed International Society for Heart and Lung Transplantation 2R acute cellular rejection on first biopsy. At last follow-up, all 15 recipients were alive past 30-days. Conclusions Cardiac DCD provides an opportunity to increase the availability of donor hearts for transplantation. Utilizing TA-NRP with cold static storage, we have extended the cold ischemic time of DCD allografts to almost 3 hours, allowing for inter-hospital organ transport.

We used routinely collected programme data on people living with HIV in Oman who started ART in 2014–2018 to assess retention on ART, viral suppression, attrition (mortality or loss to follow-up [L...

Living donor liver transplantation (LDLT) emerged in the 1980s as a viable alternative to scarce cadaveric organs for pediatric patients. However, pediatric waitlist mortality remains high. Long-term outcomes of living and deceased donor liver transplantation (DDLT) are inconsistently described in the literature. Our aim was to systematically review the safety and efficacy of LDLT after 1 year of transplantation among pediatric patients with all causes of liver failure. We searched the MEDLINE, Medline-in-Process, MEDLINE Epub Ahead of Print, Embase + Embase Classic (OvidSP), and Cochrane (Wiley) from February 1, 1947 to February 26, 2020, without language restrictions. The primary outcomes were patient and graft survival beyond 1 year following transplantation. A meta-analysis of unadjusted and adjusted odds and hazard ratios was performed using a random-effects model. A total of 24 studies with 3677 patients who underwent LDLT and 9098 patients who underwent DDLT were included for analysis. In patients with chronic or combined chronic liver failure and acute liver failure (ALF), 1-year (odds ratio [OR], 0.68; 95% confidence interval [CI], 0.53-0.88), 3-year (OR, 0.73; 95% CI, 0.61-0.89), 5-year (OR, 0.71; 95% CI, 0.57-0.89), and 10-year (OR, 0.42; 95% CI, 0.18-1.00) patient and 1-year (OR, 0.50; 95% CI, 0.35-0.70), 3-year (OR, 0.55; 95% CI, 0.37-0.83), 5-year (OR, 0.5; 95% CI, 0.32-0.76), and 10-year (OR, 0.26; 95% CI, 0.14-0.49) graft survival were consistently better in LDLT recipients compared with those in DDLT recipients. In patients with ALF, no difference was seen between the 2 groups except for 5-year patient survival (OR, 0.60; 95% CI, 0.38-0.95), which favored LDLT. Sensitivity analysis by era showed improved survival in the most recent cohort of patients, consistent with the well-described learning curve for the LDLT technique. LDLT provides superior patient and graft survival outcomes relative to DDLT in pediatric patients with chronic liver failure and ALF. More resources may be needed to develop infrastructures and health care systems to support living liver donation.

To evaluate whether graft-type and tunnel location in ACL reconstruction impact patient-reported outcomes in individuals over the age of 45. From 2015 to 2018, patients over 45 years old undergoing primary ACL reconstruction without multi-ligamentous injuries were enrolled in an institutional registry. Baseline International Knee Documentation Committee (IKDC) subjective scores, Knee Injury and Osteoarthritis Outcome Scores (KOOS), Marx Activity Scale, and patient characteristics were collected. Follow-up occurred at a minimum of two years to obtain patient-reported outcomes. Of the 51 patients who qualified for the study, 44 (86.3%) patients were available at a minimum of two years after surgery date (range 24–60 months). Average age at time of surgery of the available patients was 51.6 ± 4.87 (range 45–66). Between femoral tunnel drilling methods, there were no differences in the proportion of patients achieving clinically significant improvement or post-operative outcome scores. While patients who received patellar tendon autografts were more likely to achieve clinically significant improvement in the KOOS sports subscale, there were no other differences in outcomes measures between graft types. Two patients had a retear of their graft, and an additional five patients complained of subjective instability. In patients over the age of 45, neither the method used to create the femoral tunnel nor the graft type used in ACL reconstruction caused a significant difference in post-operative PROMs with a minimum of two years of follow-up. Therapeutic IV, Case Series.

Research question What is the clinical experience of patients who have undergone planned oocyte cryopreservation and oocyte thawing and warming? Design Retrospective observational cohort study. All women who completed planned oocyte cryopreservation at a single large university-affiliated fertility centre between June 2006 and October 2020 were identified, including the subset who returned to use their oocytes. Patients who underwent oocyte cryopreservation for medical reasons were excluded. Baseline demographics, oocyte cryopreservation and thawing–warming cycle parameters, and clinical outcomes, were extracted from the electronic medical record. The primary outcome was cumulative live birth rate (LBR), and secondary outcomes were cumulative clinical pregnancy rate (CPR), and CPR and LBR per transfer. Results were stratified by age at time of cryopreservation ( Results Of 921 patients who underwent planned oocyte cryopreservation, 68 (7.4%) returned to use their oocytes. Forty-six patients (67.6%) completed at least one embryo transfer. The CPR per transfer was 47.5% and LBR was 39.3%. The cumulative LBR per patient who initiated thawing–warming was 32.4%. Cycle outcomes were not significantly different in patients aged younger than 38 years and those aged 38 years or over. No patient aged 40 years or older (n = 6) was successful with their cryopreserved oocytes. Ten patients (14.7%) who were unsuccessful with their cryopreserved oocytes achieved a live birth using donor oocytes, with most (7/10) of these patients aged 38 years and older. Conclusion Only a small percentage of patients returned to use their oocytes, and 32% of those were able to achieve a live birth.

(1) To describe changes in arterial stiffness and heart rate variability (HRV) over a 5-year interval, (2) examine changes by sex and race–ethnicity, and (3) evaluate the risk factors associated with the longitudinal changes in arterial stiffness and HRV. Participants with youth-onset type 2 diabetes enrolled in the observational follow-up phase of the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial had arterial stiffness [(pulse wave velocity, augmentation index, brachial distensibility] and six indices of HRV measured 5 years apart. Multivariable linear regression models assessed risk factors associated with changes in the outcomes over time. At initial vascular assessment, the 304 participants were a mean age of 21 years, 34% male, and had a mean diabetes duration of 8 years. In more than half the cohort pulse wave velocity, augmentation index and HRV increased over 5 years (p

Minimally invasive surgery has taken over the hernia surgeries in popularity in many countries. Laparoscopic totally extra-peritoneal (TEP) hernia with meshplasty is one of the techniques. A lot of new meshes for laparoscopic hernia surgery have been developed over years. Polypropylene mesh that has been traditionally used has been compared head to head with 3D anatomically shaped large pore polypropylene mesh (3D mesh) and is an emerging alternative that needs no or minimal fixation. We performed a randomised controlled trial enrolling 50 patients with inguinal hernia, randomising 25 patients to receive laparoscopic totally extra-peritoneal repair (TEP) of inguinal hernia using 3D mesh (3DM) and 25 patients to receive laparoscopic TEP repair of inguinal hernia using light weight polypropylene mesh (LWPM). The end points of the study were mesh placement time, postoperative pain, seroma formation, hospital stay, chronic groin pain, sensory impairment and recurrence. We followed up the patients for 3 months. We found that 3DM had less mesh fixation time 12.72 min (p = 0.0001) and less postoperative pain which was statistically significant, but postoperative seroma formation, chronic groin pain, duration of hospital stay, and sensory impairment had no significant difference as compared to LWPM. We also found no recurrence rate in both mesh repair techniques at end of 3-month follow-up. The use of 3D mesh for laparoscopic inguinal hernia repair provides advantages in terms of less fixation time and easy manipulation and conformation of the mesh at the hernia site.

BACKGROUND Plasma proadrenomedullin (proADM) is a promising biomarker to predict disease severity in community-acquired pneumonia (CAP). Urinary biomarkers offer advantages over blood, including ease of collection. We evaluated the association between urinary proADM and disease severity in pediatric CAP. METHODS We performed a prospective cohort study of children 3 months to 18 years with CAP. Urinary proADM/creatinine (Cr) was calculated. Disease severity was defined as: mild (discharged home), mild-moderate (hospitalized but not moderate-severe or severe), moderate-severe (eg, hospitalized with supplemental oxygen and complicated pneumonia) and severe (eg, vasopressors and invasive ventilation). Outcomes were examined using logistic regression within the cohort with suspected CAP and in a subset with radiographic CAP. RESULTS Of the 427 children included, higher proADM/Cr was associated with increased odds of severe disease compared with nonsevere disease [suspected CAP, odds ratio (OR) 1.02 (95% confidence interval (CI) 1.003, 1.04); radiographic CAP, OR 1.03 (95% CI 1.01, 1.06)] when adjusted for other covariates. ProADM/Cr had an area under the receiver operating characteristic curve of 0.56 (threshold 0.9 pmol/mg) to differentiate severe from nonsevere disease in suspected CAP and 0.65 in radiographic CAP (threshold 0.82 pmol/mg). Healthy controls had less proADM in their urine (median, 0.61 pmol/mg) compared with suspected (0.87 pmol/mg, P = 0.018) and radiographic (0.73 pmol/mg, P = 0.016) CAP. CONCLUSIONS Urinary proADM/Cr ratio measured at the time of emergency department visit was statistically associated with the development of severe outcomes in children with CAP, with stronger discriminatory performance in radiographic disease.

Papillon-Lefevere syndrome is a very rare autosomal recessive trait characterized by palmoplantar hyperkeratosis and severe generalized early-onset periodontitis leading to premature loss of primary and permanent dentitions. Various etiopathogenesis factors are associated with syndrome. The palmoplantar keratoderma typically has its onset between the ages of 1 and 4 years and severe periodontitis starts at age of 3-4 years. A dentist plays an important role in early diagnosing and preserving remaining teeth in oral cavity. This case series describes three cases of PLS in siblings with consanguineously married parents. All siblings in the family were affected which makes this a rare case. Keywords: Consanguineous, Palmoplantar keratosis, Periodontitis, Cathepsin­ C gene

Objective Literature regarding utility of 68 Ga-DOTATATE PET/CT in insulinoma localization across various subgroups [benign/malignant/multiple endocrine neoplasia-1 (MEN-1) syndrome associated] remains scarce. In this study, the performance of 68 Ga-DOTATATE PET/CT was compared with contrast-enhanced computed tomography (CECT) and 68 Ga-NODAGA-Exendin-4 PET/CT (whenever available) in an endogenous hyperinsulinemic hypoglycemia (EHH) cohort. Design Retrospective audit. Patients EHH patients [N = 36, lesions (n) = 49, final diagnosis: benign sporadic insulinoma (BSI) (N = 20), malignant insulinoma (N = 4, n = 14), MEN-1 syndrome associated insulinoma (N = 9, n = 15), Munchausen syndrome (N = 2) and drug-induced hypoglycemia (N = 1)] having both preoperative imaging modalities (CECT and 68 Ga-DOTATATE PET/CT). Measurements Per-lesion sensitivity (Sn) and positive predictive value (PPV) for histopathological diagnosis of insulinoma. Results Sn and PPV of 68 Ga-DOTATATE PET/CT were 67.3% and 89.2%; 55% and 100%; 85.7% and 100%; and 66.7% and 77% for overall EHH, BSI, malignant, and MEN-1 syndrome associated insulinoma cohorts respectively. Despite having comparatively lower sensitivity in BSI cohort, 68 Ga-DOTATATE PET/CT localized a pancreatic tail lesion missed by other modalities. 68 Ga-DOTATATE PET/CT had comparatively higher sensitivity in malignant insulinoma than BSI cohort. 68 Ga-DOTATATE PET/CT also paved the way for successful response to 177 Lu-based peptide receptor radionuclide therapy (PRRT). In MEN-1 cases, lower PPV as compared with BSI was due to uptake in non-insulinoma pancreatic neuroendocrine tumours (Pan-NET). Conclusions 68 Ga-DOTATATE PET/CT has supplemental role in selected cases of BSI with negative and/or discordant results with CECT and 68 Ga-NODAGA-Exendin-4 PET/CT. In malignant insulinoma, 68 Ga-DOTATATE-PET/CT has an additional theranostic potential. Interference due to uptake in non-insulinoma Pan-NET in MEN-1 syndrome may hinder insulinoma localization with 68 Ga-DOTATATE-PET/CT.

As the COVID-19 pandemic has continued to spread, studies have shown that hospitalized COVID-19 patients are at significant risk for developing acute kidney injury (AKI), which can cause increased morbidity, the need for dialysis treatment, chronic kidney diseases, and even death. In this paper, we present a proof-of-concept study for the utilization of combination therapeutic-loaded dual-targeted biodegradable nanoparticles (NPs) to treat concurrent AKI and COVID-19 in patients by delivering the therapeutics across the gut epithelial barrier and to the kidney, in order to lower the viral load as well as reduce the symptoms of AKI. Despite recent vaccination efforts and the end of the COVID-19 pandemic in sight, problems related to the long-term effects of COVID-19 will continue to persist, including impacts on patients suffering from AKI and other chronic renal conditions. Therefore, the dual-targeted blended polymeric NP developed in this study to treat concurrent COVID-19 infection and AKI is a useful proof-of-concept nanoplatform for future treatments of these complications.

BACKGROUND AND OBJECTIVESClinicians evaluating for herpes simplex virus (HSV) in febrile infants must balance detection with overtesting, and there is no universally accepted approach to risk stratification. We aimed to describe variation in diagnostic evaluation and empirical acyclovir treatment of infants aged 0 to 60 days presenting with fever and determine the association between testing and length of stay (LOS).METHODSIn this retrospective 44-hospital observational study, we used the Pediatric Health Information System database to identify infants aged ≤60 days evaluated for fever in emergency departments from January 2016 through December 2017. We described hospital-level variation in laboratory testing, including HSV, imaging and other diagnostic evaluations, acyclovir use, and LOS. We assessed the relationship between HSV testing and LOS using generalized linear mixed effects models adjusted for age and illness severity.RESULTSIn 24 535 encounters for fever, the median HSV testing frequency across hospitals was 35.6% (interquartile range [IQR]: 28.5%–53.5%) for infants aged 0 to 21 days and 12% (IQR: 8.6%–15.7%) for infants aged 22 to 60 days. Among HSV-tested patients, median acyclovir use across hospitals was 79.2% (IQR: 68.1%–89.7%) for those aged 0 to 21 days and 63.6% (IQR: 44.1%–73%) for those aged 22 to 60 days. The prevalence of additional testing varied substantially by hospital and age group. Risk-adjusted LOS for HSV-tested infants was significantly longer than risk-adjusted LOS for those not tested (2.6 vs 1.9 days, P < .001).CONCLUSIONSSubstantial variation exists in diagnostic evaluation and acyclovir use, and infants who received HSV testing had a longer LOS than infants who did not. This variability supports the need for further studies to help clinicians better risk-stratify febrile infants and to guide HSV testing and treatment decisions.

Background: Annual in-hospital respiratory evaluations (AREs) during wakefulness and sleep are recommended to assess ventilatory requirements in patients with congenital central hypoventilation syndrome (CCHS) aged ≥2–3 years based on expert consensus. This study aimed to determine if AREs in patients with CCHS led to changes in ventilatory management. Methods: Retrospective review of patients with CCHS who underwent AREs with or without polysomnography between 2017 and 2019 was conducted. Clinical symptoms, results of AREs, and subsequent changes in ventilatory management were analyzed. Results: We identified 10 patients with CCHS aged 4–20 years. All patients required assisted ventilation (AV) only during sleep delivered by positive pressure ventilation via tracheostomy (n = 7) or diaphragm pacing (n = 3). In total, 7 (70%) patients had abnormal oxygenation and/or ventilation requiring changes in ventilator settings or duration of AV. Six patients required an increase in settings and/or duration of AV, and only 1 patient required a decrease in ventilator settings. Two patients had awake hypercapnia during a routine outpatient visit that improved following increase in ventilator settings and a period of continuous AV. One patient who was previously ventilator-dependent only during sleep was identified to require 16 h per day of AV. All patients (n = 3) who reported symptoms such as headache or oxygen desaturations during sleep required an increase in ventilator settings. Conclusion: We report a high prevalence of changes in AV management following an ARE. Our results demonstrate the importance of regular AREs in patients with CCHS to assess their ventilatory requirements and optimize AV.

Objectives The aim of this study was to evaluate clinical characteristics, mechanisms of failure, and outcomes of transcatheter aortic valve replacement (TAVR) explantation. Background Surgical explantation following TAVR may be required for structural valve degeneration, paravalvular leak, infection, or other reasons. However, in-depth data on indications and outcomes are lacking. Methods Data from a multicenter, international registry (EXPLANT-TAVR) of patients who underwent TAVR explantation were reviewed retrospectively. Explantations performed during the same admission as initial TAVR were excluded. Clinical and echocardiographic outcomes were evaluated. Median follow-up duration was 6.7 months (interquartile range [IQR]: 1.0-18.8 months) after TAVR explantation and was 97.7% complete at 30 days and 86.1% complete at 1 year. Results From November 2009 to September 2020, 269 patients across 42 centers with a mean age of 72.7 ± 10.4 years underwent TAVR explantation. About one quarter (25.9%) were deemed low surgical risk at index TAVR, and median Society of Thoracic Surgeons risk at TAVR explantation was 5.6% (IQR: 3.2%-9.6%). The median time to explantation was 11.5 months (IQR: 4.0-32.4 months). Balloon-expandable and self-expanding or mechanically expandable valves accounted for 50.9% and 49.1%, respectively. Indications for explantation included endocarditis (43.1%), structural valve degeneration (20.1%), paravalvular leak (18.2%), and prosthesis-patient mismatch (10.8%). Redo TAVR was not feasible because of unfavorable anatomy in 26.8% of patients. Urgent or emergency cases were performed in 53.1% of patients, aortic root replacement in 13.4%, and 54.6% had concomitant cardiac procedures. Overall survival at last follow-up was 76.1%. In-hospital, 30-day, and 1-year mortality rates were 11.9%, 13.1%, and 28.5%, respectively, and stroke rates were 5.9%, 8.6%, and 18.7%, respectively. Conclusions The EXPLANT-TAVR registry reveals that surgical risks associated with TAVR explantation are not negligible and should be taken into consideration in the lifetime management of aortic stenosis.

Objectives The aim of this study was to determine clinical and echocardiographic characteristics, mechanisms of failure, and outcomes of mitral valve (MV) surgery after transcatheter edge-to-edge repair (TEER). Background Although >100,000 mitral TEER procedures have been performed worldwide, longitudinal data on MV surgery after TEER are lacking. Methods Data from the multicenter, international CUTTING-EDGE registry were retrospectively analyzed. Clinical and echocardiographic outcomes were evaluated. Median follow-up duration was 9.0 months (interquartile range [IQR]: 1.2-25.7 months) after MV surgery, and follow-up was 96.1% complete at 30 days and 81.1% complete at 1 year. Results From July 2009 to July 2020, 332 patients across 34 centers underwent MV surgery after TEER. The mean age was 73.8 ± 10.1 years, median Society of Thoracic Surgeons risk for MV repair at initial TEER was 4.0 (IQR: 2.3-7.3), and primary/mixed and secondary mitral regurgitation were present in 59.0% and 38.5%, respectively. The median interval from TEER to surgery was 3.5 months (IQR: 0.5-11.9 months), with overall median Society of Thoracic Surgeons risk of 4.8% for MV replacement (IQR: 2.8%-8.4%). The primary indication for surgery was recurrent mitral regurgitation (33.5%), and MV replacement and concomitant tricuspid surgery were performed in 92.5% and 42.2% of patients, respectively. The 30-day and 1-year mortality rates were 16.6% and 31.3%, respectively. On Kaplan-Meier analysis, the actuarial estimates of mortality were 24.1% at 1 year and 31.7% at 3 years after MV surgery. Conclusions In this first report of the CUTTING-EDGE registry, the mortality and morbidity risks of MV surgery after TEER were not negligible, and only

Objective The aim of this study was to model the short term and 2-year overall survival (OS) for intermediate-risk and low-risk patients with severe symptomatic aortic stenosis (AS) undergoing timely or delayed transcatheter aortic valve replacement (TAVR) during the 2019 novel coronavirus (COVID-19) pandemic. Methods We developed a decision analysis model to evaluate 2 treatment strategies for both low-risk and intermediate-risk patients with AS during the COVID-19 novel coronavirus pandemic. Results Prompt TAVR resulted in improved 2-year OS compared with delayed intervention for intermediate-risk patients (0.81 vs 0.67) and low-risk patients (0.95 vs 0.85), owing to the risk of death or the need for urgent/emergent TAVR in the waiting period. However, if the probability of acquiring COVID-19 novel coronavirus is >55% (intermediate-risk patients) or 47% (low-risk patients), delayed TAVR is favored over prompt intervention (0.66 vs 0.67 for intermediate risk; 0.84 vs 0.85 for low risk). Conclusions Prompt transcatheter aortic valve replacement for both intermediate-risk and low-risk patients with symptomatic severe AS results in improved 2-year survival when local healthcare system resources are not significantly constrained by the COVID-19., Graphical abstract

BACKGROUND Improving pain control and decreasing opioid prescription and usage continue to be emphasized across both pediatric and adult populations. The purpose of this review is to provide a comprehensive assessment of recent literature and highlight new advancements pertaining to pain control in pediatric orthopaedic surgery. METHODS An electronic search of the PubMed database was performed for keywords relating to perioperative pain management of pediatric orthopaedic surgery. Search results were filtered by publication date for articles published between January 1, 2015 and December 1, 2020 and yielded 404 papers. RESULTS A total of 32 papers were selected for review based upon new findings and significant contributions in the following categories: risk factors for increased opioid usage, opioid overprescribing and disposal, nonpharmacologic interventions, nonsteroidal anti-inflammatory drugs, peripheral nerve blocks, spine surgery specific considerations, surgical pathway modifications, and future directions. CONCLUSIONS There have been many advances in pain management for pediatric patients following orthopaedic surgery. Rapid recovery surgical care pathways are associated with shorter length of stay and improved pain control in pediatric spine surgery. Opioid overprescribing continues to be common and information regarding safe opioid disposal practices should be routinely provided for pediatric patients undergoing surgery. LEVEL OF EVIDENCE Level IV-literature review.

Context Identification of modifiable risk factors, including genetic and acquired disorders of lipid and lipoprotein metabolism, is increasingly recognized as an opportunity to prevent premature cardiovascular disease (CVD) in at-risk youth. Pediatric endocrinologists are at the forefront of this emerging public health concern and can be instrumental in beginning early interventions to prevent premature CVD-related events during adulthood. Aim In this article, we use informative case presentations to provide practical approaches to the management of pediatric dyslipidemia. Cases We present 3 scenarios that are commonly encountered in clinical practice: isolated elevation of low-density lipoprotein cholesterol (LDL-C), combined dyslipidemia, and severe hypertriglyceridemia. Treatment with statin is indicated when the LDL-C is ≥190 mg/dL (4.9 mmol/L) in children ≥10 years of age. For LDL-C levels between 130 and 189 mg/dL (3.4-4.89 mmol/L) despite dietary and lifestyle changes, the presence of additional risk factors and comorbid conditions would favor statin therapy. In the case of combined dyslipidemia, the primary treatment target is LDL-C ≤130 mg/dL (3.4 mmol/L) and the secondary target non-high-density lipoprotein cholesterol 1000 mg/dL (11.3 mmol/L), dietary fat restriction remains the cornerstone of therapy, even though the landscape of medications is changing. Conclusion Gene variants, acquired conditions, or both are responsible for dyslipidemia during childhood. Extreme elevations of triglycerides can lead to pancreatitis. Early identification and management of dyslipidemia and cardiovascular risk factors is extremely important.

BACKGROUND There is limited clinical evidence of ferric carboxymaltose injection (FCM) usage in Indian pregnant women. We assessed the efficacy and safety of FCM in Indian pregnant women with moderate-to-severe anemia. METHODS Single-center, retrospective, observational data collection was conducted at a tertiary care research institute. Data of pregnant women with anemia who received FCM in their second and third trimester was retrieved and analyzed for hematological parameters at baseline and at 4 ± 2 weeks. Neonatal outcomes were also assessed. Adverse events and other safety parameters were noted. RESULTS Data of 271 patients was retrieved and analyzed for safety and data for 168 patients analyzed for efficacy. A significant increase in hemoglobin was noted with FCM in 4 weeks (1.25 g/dL; p

Introduction Accumulation of polyglutamine (polyQ) ataxin-3 (ATXN3) contributes to the pathobiology of spinocerebellar ataxia type 3 (SCA3). Recently, we showed that polyQ ATXN3 is elevated in the plasma and cerebrospinal fluid (CSF) of SCA3 patients, and has the potential to serve as a biological marker for this disease [1]. Based on these findings, we investigated whether polyQ ATXN3 can also be detected in urine samples from SCA3 patients. Methods We analyzed urine samples from 30 SCA3 subjects (including one pre-symptomatic subject), 35 subjects with other forms of ataxia, and 37 healthy controls. To quantify polyQ ATXN3 protein levels, we used our previously developed immunoassay. Results PolyQ ATXN3 can be detected in the urine of SCA3 patients, but not in urine samples from healthy controls or other forms of ataxia. There was a significant statistical association between polyQ ATXN3 levels in urine samples and those in plasma. Further, the levels of polyQ ATXN3 urine associated with an earlier age of SCA3 disease onset. Conclusion As clinical trials for SCA3 advance, urine polyQ ATXN3 protein has potential to be a useful, non-invasive and inexpensive biomarker for SCA3.

BACKGROUND The Hospital to Home Outcomes (H2O) trials examined the effectiveness of postdischarge nurse support on reuse after pediatric discharge. Unexpectedly, children randomly assigned to a nurse visit had higher rates of reuse than those in the control group. Participants in randomized control trials are heterogeneous. Thus, it is possible that the effect of the intervention differed across subgroups (ie, heterogeneity of treatment effect [HTE]). We sought to determine if different subgroups responded differently to the interventions. METHODS The H2O trial is a randomized controlled trial comparing standard hospital discharge processes with a nurse home visit within 96 hours of discharge. The second trial, H2O II, was similar, except the tested intervention was a postdischarge nurse phone call. For the purposes of the HTE analyses, we examined our primary trial outcome measure: a composite of unplanned 30-day acute health care reuse (unplanned readmission or emergency department or urgent care visit). We identified subgroups of interest before the trials related to (1) financial strain, (2) primary care access, (3) insurance, and (4) medical complexity. We used logistic regression modeling with an interaction term between subgroup and treatment group (intervention or control). RESULTS For the phone call trial (H2O II), financial strain significantly modified the effect of the intervention such that the subgroup of children with high financial strain who received the intervention experienced more reuse than their control counterparts. CONCLUSIONS In HTE analyses of 2 randomized controlled trials, only financial strain significantly modified the nurse phone call. A family’s financial resources may affect the utility of postdischarge support.

We present a multimodality pictorial review of axillary lymphadenopathy in patients recently vaccinated against COVID-19. As the mass vaccination programme continues to be rolled out worldwide in an effort to combat the pandemic, it is important that radiologists consider recent COVID-19 vaccination in the differential diagnosis of unilateral axillary lymphadenopathy and are aware of typical appearances across all imaging methods. We review current guidelines on the management of unilateral axillary lymphadenopathy in the context of recent COVID-19 vaccination.

Background Our grant from the Patient-Centered Outcomes Research Institute (PCORI) focused on the use of nurse home visits postdischarge for primarily pediatric hospital medicine patients. While our team recognized the importance of engaging parents and other stakeholders in our study, our project was one of the first funded to address transitions of care issues in patients without chronic illness; little evidence existed about how to engage acute stakeholders longitudinally. Objective This manuscript describes how we used both a short-term focused feedback model and longitudinal engagement methods to solicit input from parents, home care nurses, and other stakeholders throughout our 3-year study. Results Short-term focused feedback allowed the study team to collect feedback from hundreds of stakeholders. Initially, we conducted focus groups with parents with children recently discharged from the hospital. We used this feedback to modify our nurse home visit intervention, then used quality improvement methods with continued short-term focus feedback from families and nurses delivering the visits to adjust the visit processes and content. We also used their feedback to modify the outcome collection. Finally, during the randomized controlled trial, we added a parent to the study team to provide longitudinal input, as well as continued to solicit short-term focused feedback to increase recruitment and retention rates. Conclusion Research studies can benefit from soliciting short-term focused feedback from many stakeholders; having this variety of perspectives allows for many voices to be heard, without placing an undue burden on a few stakeholders.

Background On October 18, 2018, several changes to the donor heart allocation system were enacted. We hypothesize that patients undergoing orthotopic heart transplantation (OHT) under the new allocation system will see an increase in ischemic times, rates of primary graft dysfunction, and 1-year mortality due to these changes. Methods In this single-center retrospective study, we reviewed the charts of all OHT patients from October 2017 through October 2019. Pre- and postallocation recipient demographics were compared. Survival analysis was performed using the Kaplan-Meier method. Results A total of 184 patients underwent OHT. Recipient demographics were similar between cohorts. The average distance from donor increased by more than 150 km (p = .006). Patients in the postallocation change cohort demonstrated a significant increase in the rate of severe left ventricle primary graft dysfunction from 5.4% to 18.7% (p = .005). There were no statistically significant differences in 30-day mortality or 1-year survival. Time on the waitlist was reduced from 203.8 to 103.7 days (p = .006). Conclusions Changes in heart allocation resulted in shorter waitlist times at the expense of longer donor distances and ischemic times, with an associated negative impact on early post-transplantation outcomes. No significant differences in 30-day or 1-year mortality were observed.

Spinal instability is a challenging condition to manage in patients with cervical dystonia. Standard surgical stabilisation approaches may fail to cope with additional stress forces created by spasmodic muscles leading to construct failure either in the immediate or late post-operative period. Long-term stabilisation relies on the management of dystonic symptoms and adjunctive strategies to increase fusion success rate. We discuss the management of a challenging patient with translational C1/2 instability who had three metalwork failures with standard occipito-cervical fixation techniques within a 12 month period. A combined surgical approach using multipoint fixation, sternocleidomastoid myotomy and a vascularised fibular occiput-C2 bone graft successfully prevented further metalwork failure at over 2 years follow up.

OBJECTIVES To describe testing and treatment practices for Mycoplasma pneumoniae (Mp) among children hospitalized with community-acquired pneumonia (CAP). METHODS We conducted a retrospective cohort study using the Pediatric Health Information Systems database. We included children 3 months to 18 years old hospitalized with CAP between 2012 and 2018 and excluded children who were transferred from another hospital and those with complex chronic conditions. We examined the proportion of patients receiving Mp testing and macrolide therapy at the hospital level and trends in Mp testing and macrolide prescription over time. At the patient level, we examined differences in demographics, illness severity (eg, blood gas, chest tube placement), and outcomes (eg, ICU admission, length of stay, readmission) among patients with and without Mp testing. RESULTS Among 103 977 children hospitalized with CAP, 17.3% underwent Mp testing and 31.1% received macrolides. We found no correlation between Mp testing and macrolide treatment at the hospital level (R2 = 0.05; P = .11). Patients tested for Mp were more likely to have blood gas analysis (15.8% vs 12.8%; P < .1), chest tube placement (1.4% vs 0.8%; P < .1), and ICU admission (3.1% vs 1.4%; P < .1). Mp testing increased (from 15.8% to 18.6%; P < .001), and macrolide prescription decreased (from 40.9% to 20.6%; P < .001) between 2012 and 2018. CONCLUSIONS Nearly one-third of hospitalized children with CAP received macrolide antibiotics, although macrolide prescription decreased over time. Clinicians were more likely to perform Mp testing in children with severe illness, and Mp testing and macrolide treatment were not correlated at the hospital level.

Many patients with concussion experience visual symptoms following injury that lead to a diagnosis of convergence insufficiency, accommodative insufficiency, or saccadic dysfunction. However, these diagnostic categories are based on aggregates of clinical tests developed from a non-concussed population and therefore may not accurately describe visual deficits in the concussed population. Thus, we sought to understand individual metrics of visual dysfunction in chronically symptomatic post-concussion patients. This retrospective cross-sectional study included patients examined at the multidisciplinary concussion clinic (MDCC) at Boston Children’s Hospital over four years. Patients aged 5–21 years who had a complete assessment of eye alignment, vergence, accommodation, and visual tracking, and had visual acuity better than or equal to 20/30 in each eye were included. Patients with history of amblyopia, strabismus, or ocular pathology were excluded. Chart review yielded 116 patients who met inclusion criteria (median age 15 years, 64% female). The majority of patients (52%) experienced a single concussion and most were sports-related (50%). Clinical data show vergence, accommodation, or visual tracking deficits in 95% of patients. A receded near point of convergence (NPC, 70/116) and reduced accommodative amplitude (63/116) were the most common deficits. Both NPC and accommodative amplitude were significantly correlated with one another (r = −0.5) and with measures of visual tracking (r = −0.34). Patients with chronic post-concussion symptoms show deficits in individual metrics of vergence, accommodation and visual tracking. The high incidence of these deficits, specifically NPC and accommodative amplitude, highlights the need for a detailed sensorimotor evaluation to guide personalized treatment following concussion.

Total ankle arthroplasty is an increasingly utilized treatment for ankle arthritis due to decreasing failure rates and improved outcomes. However, the literature on this procedure remains heterogeneous with large variability in outcome reporting methods. PRISMA guidelines were used to systematically review outcome reporting measures used in prospective studies and randomized control trials on total ankle arthroplasty published in 15 high-impact journals between Jan 1, 2009-May 1, 2020. A total of 43 studies were included and outcome measures were grouped into seven categories: pain, subjective function, patient satisfaction, complications, objective function, implant survivorship, and imaging. The most common topic of study was implant design followed by differences in outcomes when comparing total ankle arthroplasty and arthrodesis. The most commonly reported outcome measure was post-surgical complications. No study reported on all seven categories, while 22 (51.2%) studies reported on four or more. Subjective measures had significant variability with fifteen different Patient Reported Outcome Measures used across the studies. While the included studies were quite comprehensive, there was little consistency in reporting outcomes after total ankle arthroplasty. With improving outcomes and techniques in total ankle arthroplasty, and thus an expected increase in utilization and number of published studies, efforts should be made to use commonly employed outcome reporting methods to facilitate comparison of results across studies.

ObjectivesHealth status (HS)/ health-related quality of life measures, completed by self or proxy, are important outcome indicators. Most HS literature on children born preterm includes adolescents and adults with limited data at preschool age. This study aimed to describe parent-reported HS in a large national cohort of extreme preterm children at preschool age and to identify clinical and sociodemographic variables associated with HS.MethodsInfants born before 29 weeks’ gestation between 2009 and 2011 were enrolled in a prospective longitudinal national cohort study through the Canadian Neonatal Network (CNN) and the Canadian Neonatal Follow-Up Network (CNFUN). HS, at 36 months’ corrected age (CA), was measured with the Health Status Classification System for Pre-School Children tool completed by parents. Information about HS predictors was extracted from the CNN and CNFUN databases.ResultsOf 811 children included, there were 79, 309 and 423 participants in 23–24, 25–26 and 27–28 weeks’ gestational age groups, respectively. At 36 months’ CA, 78% had a parent-reported health concern, mild in >50% and severe in 7%. Most affected HS attributes were speech (52.1%) and self-care (41.4%). Independent predictors of HS included substance use during pregnancy, infant male sex, Score for Neonatal Acute Physiology-II, bronchopulmonary dysplasia, severe retinopathy of prematurity, caregiver employment and single caregiver.ConclusionMost parents expressed no or mild health concerns for their children at 36 months’ CA. Factors associated with health concerns included initial severity of illness, complications of prematurity and social factors.

Background Coronavirus disease 2019 (COVID‐19) has significantly impacted the healthcare landscape in the United States in a variety of ways including a nation‐wide reduction in operative volume. The impact of COVID‐19 on the availability of donor organs and the impact on solid organ transplant remains unclear. We examine the impact of COVID‐19 on a single, large‐volume heart transplant program. Methods A retrospective chart review was performed examining all adult heart transplants performed at a single institution between March 2020 and June 2020. This was compared to the same time frame in 2019. We examined incidence of primary graft dysfunction, continuous renal replacement therapy (CRRT) and 30‐day survival. Results From March to June 2020, 43 orthotopic heart transplants were performed compared to 31 performed during 2019. Donor and recipient demographics demonstrated no differences. There was no difference in 30‐day survival. There was a statistically significant difference in incidence of postoperative CRRT (9/31 vs. 3/43; p = .01). There was a statistically significant difference in race (23 W/8B/1AA vs. 30 W/13B; p = .029). Conclusion We demonstrate that a single, large‐volume transplant program was able to grow volume with little difference in donor variables and clinical outcomes following transplant. While multiple reasons are possible, most likely the reduction of volume at other programs allowed us to utilize organs to which we would not have previously had access. More significantly, our growth in volume was coupled with no instances of COVID‐19 infection or transmission amongst patients or staff due to an aggressive testing and surveillance program.

Although the erythema migrans (EM) skin rash is traditionally considered a hallmark of Lyme disease, other dermatological manifestations of the tickborne disease are less well known. We describe a 49-year-old woman with erosive genital ulcerations, secondary EM rashes and jagged skin lesions associated with Lyme disease. The skin rashes exhibited fibers characteristic of Morgellons disease. Molecular testing confirmed the presence of Borrelia DNA in both vaginal culture and serum specimens. In further studies on a secondary EM lesion containing filaments, Gömöri trichrome staining revealed the presence of collagen in the filaments, while Dieterle and anti-Borrelia immunostaining revealed intracellular and extracellular Borrelia organisms. Intracellular staining for Borrelia was also observed in lymphocytic infiltrates. Lyme disease may present with a variety of genital lesions and dermatological manifestations including Morgellons disease. Careful evaluation is required to determine the presence of Borrelia organisms associated with these dermopathies.

BACKGROUND: TB is the leading cause of mortality among people living with HIV (PLHIV), for whom isoniazid preventive therapy (IPT) has a proven mortality benefit. Despite WHO recommendations, countries have been slow in scaling up IPT. This study describes processes, challenges, solutions, outcomes and lessons learned during IPT scale‐up in Kenya.METHODS: We conducted a desk review and analyzed aggregated Ministry of Health (MOH) IPT enrollment data from 2014 to 2018 to determine trends and impact of program activities. We further analyzed IPT completion reports for patients initiated from 2015 to 2017 in 745 MOH sites in Nairobi, Central, Eastern and Western Kenya.RESULTS: IPT was scaled up 75‐fold from 2014 to 2018: the number of PLHIV covered increased from 9,981 to 749,890. The highest percentage increases in the cumulative number of PLHIV on IPT were seen in the quarters following IPT pilot projects in 2014 (49%), national launch in 2015 (54%), and HIV treatment acceleration in 2016 (158%). Among 250,069 patients initiating IPT from 2015 to 2017, 97.5% completed treatment, 0.2% died, 0.8% were lost to follow‐up, 1.0% were not evaluated, and 0.6% discontinued treatment.CONCLUSIONS: IPT can be scaled up rapidly and effectively among PLHIV. Deliberate MOH efforts, strong leadership, service delivery integration, continuous mentorship, stakeholder involvement, and accountability are critical to program success.

Purpose: Detection of persistent circulating tumor DNA (ctDNA) after curative-intent surgery can identify patients with minimal residual disease (MRD) who will ultimately recur. Most ctDNA MRD assays require tumor sequencing to identify tumor-derived mutations to facilitate ctDNA detection, requiring tumor and blood. We evaluated a plasma-only ctDNA assay integrating genomic and epigenomic cancer signatures to enable tumor-uninformed MRD detection. Experimental Design: A total of 252 prospective serial plasma specimens from 103 patients with colorectal cancer undergoing curative-intent surgery were analyzed and correlated with recurrence. Results: Of 103 patients, 84 [stage I (9.5%), II (23.8%), III (47.6%), IV (19%)] had evaluable plasma drawn after completion of definitive therapy, defined as surgery only (n = 39) or completion of adjuvant therapy (n = 45). In “landmark” plasma drawn 1-month (median, 31.5 days) after definitive therapy and >1 year follow-up, 15 patients had detectable ctDNA, and all 15 recurred [positive predictive value (PPV), 100%; HR, 11.28 (P < 0.0001)]. Of 49 patients without detectable ctDNA at the landmark timepoint, 12 (24.5%) recurred. Landmark recurrence sensitivity and specificity were 55.6% and 100%. Incorporating serial longitudinal and surveillance (drawn within 4 months of recurrence) samples, sensitivity improved to 69% and 91%. Integrating epigenomic signatures increased sensitivity by 25%–36% versus genomic alterations alone. Notably, standard serum carcinoembryonic antigen levels did not predict recurrence [HR, 1.84 (P = 0.18); PPV = 53.9%]. Conclusions: Plasma-only MRD detection demonstrated favorable sensitivity and specificity for recurrence, comparable with tumor-informed approaches. Integrating analysis of epigenomic and genomic alterations enhanced sensitivity. These findings support the potential clinical utility of plasma-only ctDNA MRD detection.

We conducted a cross-sectional analysis to determine the rate of retention in HIV care and the factors associated with loss to follow-up (LTFU) among Omani adults living with HIV who were linked to care as of 31 December 2019. Patients (n = 1610) were identified from a central national HIV surveillance dataset. The majority (68.3%) of patients were male, and the median age was 39 years (IQR, 31-48 years). A total of 1480 patient (91.9%) were retained in care. On multivariate analysis, compared to those who received antiretroviral therapy (ART), patients who had never been on ART were 6.8 (95% CI: 3.05-15.16) times more likely to be lost to follow-up. Patients who had a latest HIV viral load (VL) of 200-999 copies/ml (adjusted odds ratio [aOR]: 4.92, 95% CI: 2.27-10.69) and ≥ 1000 copies/ml (aOR: 15.03, 95% CI: 8.31-27.19) compared to those who had a latest HIV VL of

In January 2016, the National AIDS Programme (NAP) in Oman introduced a package of interventions, including capacity building for service providers, to improve the quality of HIV services.To report the impact of these interventions on the rate of vertical HIV transmission in the period from January 2016 to December 2019. We also describe the virological and obstetric outcomes for HIV-infected pregnant women.This was a medical record review of 94 HIV-positive pregnant women (median age 32 years; interquartile range 25-34 years) reported to NAP in 2016-2019.There were 110 pregnancies in 94 women. The majority (75.3%, 61/81) of women were diagnosed with HIV infection from routine antenatal screening, with 60% (66/110) of pregnancies occurring in women who knew their HIV status at conception. Caesarean section was the most common (50%) mode of delivery. The preterm labour and low birth weight rates were 21.2% and 15.9%, respectively. The antiretroviral coverage during pregnancy was 95.5%, with most (87.8%) women reporting excellent or good adherence. The majority (81.6%) of women achieved HIV viral load of400 copies/ml at or near delivery. Almost all infants (99%) were given prophylactic antiretrovirals. The rate of mother-to-child transmission of HIV was 1%.The obstetric and virological outcomes for HIV-infected pregnant women delivered in 2016-2019 were favourable, with a low rate of mother-to-child transmission of HIV. Oman is now in the process of finalizing application of World Health Organization validation of elimination of mother-to-child transmission of HIV.القضاء على انتقال فيروس العوز المناعي البشري من الأم إلى الطفل في عُمان: قصة نجاح من الشرق الأوسط.علي القالب، فاطمه الهنائي، جميله العبري، سمير شاه، زيانه الحبسي، مها الفروي، ريتشارد لاو، حنان الكندي، عادل الوهيبي، أمال المعاني، بدر الرواحي، سعيد اللمكي، سيف العبري.في يناير/كانون الثاني 2016 ، قدَّم البرنامج الوطني للإيدز في عُمان حزمة من التدخلات، اشتملت على بناء قدرات مقدمي الخدمات، بغرض تحسين جودة الخدمات الخاصة بفيروس العوز المناعي البشري.هدفت هذه الدراسة الى الإبلاغ عن تأثير التدخلات على معدل الانتقال الرأسي لفيروس العوز المناعي البشري في الفترة من يناير/كانون الثاني 2016 إلى ديسمبر/كانون الأول 2019. أيضًا وصفنا النتائج الفيروسية والتوليدية للحوامل المصابات بفيروس العوز المناعي البشري.روجعت السجلات الطبية ل 94 حاملً مصابات بفيروس العوز المناعي البشري (العمر الوسيط 32 سنة؛ المدى الرباعي للعمر 25-34 سنة) اللواتي أُبلغ عنهن إلى البرنامج الوطني للإيدز في الفترة 2016-2019.حدثت 110 أحمال لدى 94 امرأة. وشُخِّصت إصابة غالبية النساء (٪75.3، 61/ 81) بفيروس العوز المناعي البشري من خلال الفحص الروتيني قبل الولادة، مع حدوث حمل لدى ٪60 (66/ 110) من نساء كن يعرفن إصابتهن بالفيروس عند الحمل. وكانت العملية القيصرية أكثر طرق الولادة شيوعًا (٪50). وبلغت معدلات الولادة المبتسرة وانخفاض وزن المواليد ٪21.2 و٪15.9 على التوالي. وبلغت التغطية بمضادات الفيروسات القهقرية خلال الحمل ٪95.5 ، مع التزام معظم النساء (٪87.8) التزامًا ممتازًا أو جيدًا بالعلاج. وحققت غالبية النساء (٪81.6) حملً فيروسيًّا لأقل من 400 نسخة/ مل عند الولادة أو بالقرب منها. وأُعطِيَ جميع الرضع تقريبًا (٪99) مضادات الفيروسات القهقرية الوقائية. وبلغ معدل انتقال العدوى بفيروس العوز المناعي البشري من الأم إلى الطفل ٪1.لقد كانت النتائج التوليدية والفيروسية للحوامل المصابات بفيروس العوز المناعي البشري التي جرت في الفترة 2016-2019 مب ةِّش، مع انخفاض معدل انتقال فيروس العوز المناعي البشري من الأم إلى الطفل. ان عُمان الآن بصدد وضع اللمسات الأخيرة على تطبيق مصادقة منظمة الصحة العالمية على القضاء على انتقال فيروس العوز المناعي البشري من الأم إلى الطفل.Élimination de la transmission mère-enfant du VIH à Oman : un exemple de réussite au Moyen-Orient.En janvier 2016, le Programme national de lutte contre le sida à Oman a mis en place un ensemble d’interventions, comprenant le renforcement des capacités des prestataires de services, afin d’améliorer la qualité des services de lutte contre le VIH.Signaler l’impact de ces interventions sur le taux de transmission verticale du VIH au cours de la période comprise entre janvier 2016 et décembre 2019. Nous décrivons également les résultats virologiques et obstétricaux pour les femmes enceintes touchées par le VIH.Il s’agissait d’un examen des dossiers médicaux, notifiés au Programme national de lutte contre le sida de 2016 à 2019, pour 94 femmes enceintes séropositives (âge médian : 32 ans ; intervalle interquartile : 25-34 ans).Il y avait 110 grossesses chez 94 femmes. La majorité (75,3 %, 61/81) des femmes ont reçu un diagnostic d’infection par le VIH lors du dépistage prénatal systématique, et 60 % (66/110) des grossesses se sont produites chez des femmes qui connaissaient leur statut sérologique au moment de la conception. La césarienne était le mode d’accouchement le plus courant (50 %). Les taux de travail prématuré et de faible poids de naissance étaient respectivement de 21,2 % et 15,9 %. La couverture antirétrovirale pendant la grossesse était de 95,5 %, la plupart des femmes (87,8 %) signalant une excellente ou une bonne observance. La majorité (81,6 %) des femmes ont atteint une charge virale VIH inférieure à 400 copies/ml à l'accouchement ou à proximité. Presque tous les nourrissons (99 %) ont reçu des antirétroviraux prophylactiques. Le taux de transmission mère-enfant du VIH était de 1 %.Les résultats obstétricaux et virologiques des femmes enceintes séropositives ayant accouché entre 2016 et 2019 étaient favorables, avec un faible taux de transmission mère-enfant du VIH. Oman finalise actuellement l’application de la validation de l’élimination de la transmission mère-enfant du VIH par l’Organisation mondiale de la Santé.

OBJECTIVE To evaluate inter-rater agreement for sonographic classification of stomach position (as a surrogate for liver herniation) in fetal left congenital diaphragmatic hernia (LCDH) among: (i) fetal medicine specialists from the North American Fetal Therapy Network (NAFTNet) centers within and without the fetal endoscopic tracheal occlusion (FETO) consortium and in comparison to an expert external reviewer (ER1); and (iii) among two expert ERs (ER1 and ER2). METHODS Forty-eight physicians from 26 NAFTNet centers and 2 ERs were asked to assess 13 sonographic clips of isolated LCDH and classify stomach position as "intra-abdominal," "anterior left chest," "mid to posterior left chest," or "retro-cardiac" based on the classification published by Basta et al.8 Interrater agreement was assessed by determining proportion of stomach position ratings concordant amongst NAFTNet participants and ER1. Agreement for stomach position between ERs was calculated using kappa statistics. RESULTS Agreement for stomach position was 69% (39%-85%; n = 19) and 54% (23%-92%; n = 29) among FETO and non-FETO NAFTNet participants, respectively, when compared to ER1. Most disagreement in stomach position was related to a discrepancy of one position. ERs were in agreement for stomach position in 5 of 13 cases (38.5%) and inter-rater agreement was highest for "anterior" stomach position. CONCLUSION Interrater agreement for stomach position assessment in CDH was poor across NAFTNet and indeed amongst expert reviewers.
