Adding gentamicin to silk fibroin enhances both the antibacterial performance and degradation rate of silk-based materials. The increased material degradation rate can affect the strength of early internal fixation, resulting in internal fixation failure. This study sought to adjust the gentamicin concentration to control the material degradation rate, thereby better meeting clinical application requirements. The in vitro degradation, water absorption rate, and expansion rate of silk-based materials containing different gentamicin concentrations were studied. A gentamicin-loaded silk-based screw was implanted into the femurs of New Zealand rabbits. Micro-computed tomography was used to measure the screw diameter, which was then used to calculate the degradation rate. The specimens were stained with hematoxylin and eosin and Masson’s trichrome. The in vitro results revealed increasing material degradation rates with increasing gentamicin concentration but no significant differences in water absorption rates with different gentamicin concentrations. The degradation rates of gentamicin-loaded (4 mg/g) silk-based rod-like materials were approximately 11.08% at three months in vitro and 9.4% in the animal experiment. The time for complete degradation was predicted from the fitting curve to be approximately 16 months. No inflammatory hyperplasia was observed in bone or soft tissue. The degradation and biocompatibility of the material containing 4 mg/g gentamicin meet clinical application requirements, and previous experimental results demonstrate good antibacterial performance of materials containing this gentamicin concentration.

The appropriateness of intensive care unit (ICU) admission of patients with metastatic cancer remains debated. We aimed to examine the short-term outcomes and their temporal pattern in critically ill patients with metastatic disease. We used state-wide data to identify hospitalizations aged ≥18 years with metastatic cancer admitted to ICU in Texas during 2010–2014. Multivariable logistic regression modeling was used to examine the factors associated with short-term mortality and its temporal trends among all ICU admissions and those undergoing mechanical ventilation. Among 136,644 ICU admissions with metastatic cancer, 50.8% were aged ≥65 years, with one or more organ failures present in 53.3% and mechanical ventilation was used in 11.1%. The crude short-term mortality among all ICU admissions and those mechanically ventilated was 28.1% and 62.0%, respectively. Discharge to home occurred in 57.1% of all ICU admissions. On adjusted analyses, short-term mortality increased with rising number of organ failures (adjusted OR (aOR) 1.399, 95% CI 1.374 to 1.425), while being lower with chemotherapy (aOR 0.467, 95% CI 0.432 to 0.506) and radiation therapy (aOR 0.832, 95% CI 0.749 to 0.924), and decreased over time (aOR 0.934 per year, 95% CI 0.924 to 0.945). Predictors of short-term mortality were largely similar among those undergoing mechanical ventilation. Most ICU admissions with metastatic cancer survived hospitalization, although short-term mortality was very high among those undergoing mechanical ventilation. Short-term mortality decreased over time and was lower among those receiving chemotherapy and radiation therapy. These findings support consideration of critical care in patients with metastatic cancer, but underscore the need to address patient-centered goals of care ahead of ICU admission.

Introduction This study aimed to describe the use of awake prone positioning (APP) and conventional oxygen therapy (COT) in patients with suspected coronavirus disease (COVID-19) and respiratory failure in a limited-resource setting. Methods This was a retrospective cohort study of hospitalized patients aged ≥18 years old who were placed in an awake prone position due to hypoxemic respiratory failure and suspected COVID-19. The patients were selected from a tertiary center in Cartagena, Colombia, between March 1, 2020, and August 31, 2020. Demographic, clinical, and laboratory variables were collated, and all the variables were compared between the groups. Results The median age of the participants was 63 (IQR, 48.8-73) years (survivors: 59 [IQR, 43.568] years vs. non-survivors: 70 [IQR, 63-78] years, P ≤ .001). Of the 1470 patients admitted for respiratory symptoms, 732 (49.8%) were hospitalized for more than 24 h, and 212 patients developed respiratory failure and required COT and APP (overall hospital mortality, 34% [73/212]). The mean rank difference in PaO2/FiO2 before and after APP was higher in the survivors than in the non-survivors (201.1-252.6, mean rank difference = 51.5, P = .001 vs. 134.1-172.4, mean rank difference = 38.28, P = .24, respectively). Conclusion While using COT in conjunction with APP can improve respiratory failure in patients with suspected COVID-19 in low-resource settings, persistent hypoxemia after APP can identify patients with higher mortality risk. More evidence is needed to establish the role of this strategy.

Pedicled buccal fat flaps have been adopted in primary Furlow double-opposing Z-plasty palatoplasty to reduce oronasal fistula formation or to attenuate maxillary growth disturbance. We combined both goals in a single intervention. This study describes a series of 33 modified Furlow small double-opposing Z-plasty palatoplasties reinforced with a middle layer of pedicled buccal fat flaps between the oral and nasal layers for full coverage of the dissected palatal surfaces, with rapid mucosalization of lateral relaxing incisions and no dehiscence or fistula formation.

Purpose This study aimed to analyze biometry values cutoffs for the choice of the best intraocular lens power calculation formula for AcrySof IQ Vivity intraocular lens. Methods The study was designed as interventional case series with 3 months of follow-up. Intraocular lens power calculation formulas included Barrett Universal II and SRK/T. The first was adopted for the intraocular lens power choice. The quantitative analysis focused on the identification of specific biometric cutoffs considering axial length, anterior chamber depth, and corneal powers. We included only the dominant eye in the statistical analysis. Results One hundred and eight eyes of 54 patients (23 males; mean age 62 ± 5 years) with no ocular diseases were included. Best-corrected visual acuity improved from 0.3 ± 0.2 to 0.0 ± 0.0 logMAR. All the eyes reached spectacles-free far and intermediate visions; a spherical addition of + 1.0D was necessary to adjust near vision. We identified significant quantitative cutoffs based on axial length and anterior chamber depth. Barrett Universal II resulted the best formula for eyes disclosing an axial length >25 mm, whereas SRK/T turned out to be the best choice for the eyes characterized by an anterior chamber depth Conclusions Axial length and anterior chamber depth influence the choice of Barrett Universal II and SRK/T formulas. Quantitative biometric cutoffs may be useful to discriminate the best formula to be adopted.

Objective The aim of this study was to describe coping strategies used by parents of children with cleft palate with or without a cleft (CP ± L) during the early development of their children in El Salvador. Design Qualitative interviews were completed with 16 parents of children born with CP ± L who were 6 months to 6 years old. Parents were questioned about their emotions and coping during eight time periods: prenatal, birth, social interaction before the first surgery, the beginning of surgeries, social interaction after the first surgery, early childhood education (ECE), speech–language therapy, and formal education. Thematic analysis (TA) was used to identify coping strategies as conceptualized by Lazarus and Folkman (1984) . Results Four major themes emerged: (a) experienced emotions related to diagnosis, (b) interpretations related to the birth of a child with a cleft, (c) seeking and experiencing cleft treatment, and (d) social interaction of the children. During prenatal and birth stages, parents used emotion-focused strategies. A few hours to a week after birth, they used problem-focused strategies, which led them in search of treatment. Some parents used avoidance strategies during periods of social interaction before surgery, ECE, and formal education. Socioeconomic challenges impacted access to speech–language therapy. Sociocultural factors, such as discrimination, religion, and folk beliefs, appeared to influence some of the coping strategies used by parents. Conclusions Problem-focused strategies appear to be helpful in seeking surgical treatments. The emotion-focused strategy of avoidance seemed to have adverse effects in minimizing opportunities for social interaction prior to surgery and early education.

We report the results of the treatment of disorders of the distal radioulnar joint with the semi-constrained Aptis prosthesis. Nineteen patients were assessed at a mean follow-up of 7 years. All patients had been operated on previously at the wrist, forearm or elbow. The Disabilities of Arm, Shoulder and Hand score had a mean value of 40, the Patient-Rated Wrist Evaluation score had a mean of 49 and the visual analogue scale for pain had a mean of 3.9. The mean ranges of pronation, supination, wrist flexion and wrist extension were 78°, 76°, 60° and 51°, respectively. The mean grip strength was 23 kg. Complications were noted in ten patients. Eighteen patients would undergo the operation again. The 10-year cumulative survival rate was 84%. The Aptis prosthesis may be a solution to treat patients in whom previous surgery at the distal radioulnar joint has failed. Level of evidence: IV

Background: A significant number of high tibial osteotomies (HTOs) result in an overcorrected tibia and subsequent excessive lateral joint line obliquity (JLO). The correlation between excessive JLO and poor outcomes is controversial. Purpose: To evaluate the prognostic factors (including a pathological postoperative JLO) related with the outcomes of opening wedge HTO at 10 years of follow-up. Study Design: Case series; Level of evidence, 4. Methods: All patients undergoing HTO between 2004 and 2017 for medial osteoarthritis and with a postoperative hip-knee-ankle angle between 176° and 185° were included. Clinical evaluation included Knee Society Score (KSS; knee score and function score), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and visual analog scale for pain. Several mechanical and anatomic angles were measured pre- and postoperatively on long-leg weightbearing radiographs. Abnormal JLO was defined as a Mikulicz–joint line angle (MJL) ≥94° or a mechanical medial proximal tibial angle (mMPTA) ≥95°. Regression analysis was performed to evaluate the association between independent variables and each outcome. A Kaplan-Meier cumulative survival analysis was performed. Results: A total of 92 knees in 76 patients were included. The mean age of the patients was 53.5 years (SD, 9.7 years), and the mean follow-up was 129.4 months (SD, 44.4 months). Increased JLO was associated with a significant preoperative varus deformity (small preoperative hip-knee-ankle angle), increased mechanical lateral distal femoral angle, increased joint line congruency angle, and increased knee-ankle joint angle. Male sex was associated with better WOMAC scores ( P = .0277), and increased body mass index (BMI) was associated with inferior WOMAC scores ( P = .0024). A good preoperative range of motion was associated with better knee score ( P = .0399) and function score ( P = .0366) on the KSS. An increased BMI was associated with inferior KSS function scores ( P = .0317). MJL ≥94° and mMPTA ≥95° were not associated with inferior WOMAC or KSS outcomes. With indication to total knee arthroplasty as an endpoint, Kaplan-Meier analysis showed a survival rate of 98.7% at 5 years, 95.5% at 10 years, and 92.7% at 12 years. Conclusion: Increased lateral JLO (MJL ≥94° or mMPTA ≥95°) was not correlated with the clinical outcomes of opening wedge HTO at 10 years of follow-up.

Despite hypertension ranks among the leading causes of chronic kidney disease (CKD), the impact of chronic hypertensive nephropathy, the so-called ‘nephrosclerosis’ (NS), on CKD progression is often unpredictable, particularly in elderly population. We have conducted a prospective, observational study to define renal function patterns and outcomes in elderly CKD individuals with or without NS. Three hundred four individuals with an already established CKD were categorized according to the etiology of CKD. NS was defined as the presence of CKD associated with long-term essential hypertension, hypertensive retinopathy, left ventricular hypertrophy and minimal proteinuria. Time trajectories in estimated glomerular filtration rate (eGFR) (CKD-Epi) were computed over a 4-year follow-up. In addition, we analyzed the occurrence of a composite outcome of doubling of serum creatinine levels, eGFR reduction ≥25% and/or the need of chronic renal replacement therapy. CKD was secondary to nephrosclerosis (CKD-NS) in 220 (72.3%). In the whole cohort, the average estimated annual GFR slope was 1.8 mL/min/1.73 m2. eGFR decline was slower in CKD-NS as compared with others (1.4 vs 3.4 mL/min/1.73 m2; p

Purpose: To evaluate the safety and efficacy of thoracic endovascular aortic repair (TEVAR) for retrograde type A intramural hematoma (IMH) with intimal disruption in the descending aorta and report our endovascular therapeutic experience. Materials and Methods: From January 2014 to October 2020, a total of 24 consecutive patients with retrograde type A IMH with intimal disruption (intimal tear or ulcer-like projection) in the descending aorta underwent TEVAR. The demographics, clinical characteristics, treatment details, imaging information, and follow-up results were reviewed. Results: Among all patients with retrograde type A IMH, 13 (54.2%) patients presented with ulcer-like projection and 11 (45.8%) with intimal tear (aortic dissection) in the descending aorta. Successful TEVAR was achieved in all patients. There was no 30-day mortality. During a mean follow-up of 37.5 months, 1 patient (4.2%) developed permanent paralysis, 1 patient (4.2%) underwent reintervention due to the expansion of the aorta distal to the stent resulting from the enlargement of distal intimal tear at the 2 month follow up, and no other adverse events were observed. The latest computed tomographic angiography images showed that the maximum diameter of the ascending aorta and descending aorta significantly decreased after TEVAR (both pConclusion: Thoracic endovascular aortic repair for selected patients with retrograde type A intramural hematoma that presented with intimal disruption in the descending aorta is feasible and efficient, but close surveillance is needed to manage aortic-related adverse events.

Category: Ankle; Other Introduction/Purpose: Open reduction and internal fixation (ORIF) of the ankle is a common procedure performed to correct ankle fractures in many different patient populations. Diabetes, peripheral vascular disease, and osteoporosis have been identified as risk factors for postoperative complications following surgery for ankle fractures. To date, there have not been any studies evaluating postoperative outcomes in patients with bleeding disorders undergoing operative treatment for ankle fractures. The aim of this study was to determine the postoperative complication rate following ORIF of the ankle in patients with a bleeding disorder versus those without a bleeding disorder. Methods: From 2006 to 2018, patients undergoing operative treatment for ankle fracture were identified in the National Surgical Quality Improvement Program database. Two patient cohorts were defined: patients with a bleeding disorder and patients without a bleeding disorder. Patients who underwent either inpatient or outpatient ORIF of the ankle were included in this study. In this analysis, demographics, medical comorbidities, and postoperative complications variables were assessed between the two cohorts. Bivariate and multivariate analyses were performed. Results: Of 10,306 patients undergoing operative treatment for ankle fracture, 9,909 patients (96.1%) had no bleeding disorder whereas 397 patients (3.9%) had a bleeding disorder. Following adjustment on multivariate analysis, compared to patients who did not have a bleeding disorder, those with a bleeding disorder had an increased risk of any postoperative complications (OR 1.479; p=0.024), requirement for postoperative blood transfusion (OR 2.863; p=0.001), and extended length of hospital stay greater than 5 days (OR 1.455; p=0.010) (Table 1). Conclusion: Patients with bleeding disorders are at an increased risk of postoperative complications following ORIF for ankle fractures. Our study found that patients with bleeding disorders had greater odds of postoperative complications following ORIF of the ankle. Determining patient risk factors and creating optimal preoperative and perioperative management plans in patients with bleeding disorders undergoing ORIF can be beneficial in reducing postoperative complications, improving patient outcomes, and reducing overall cost.

Approximately eight billion therapeutic injections are administered outside of medical treatment facilities annually. The management of diabetes mellitus (DM) includes self-monitoring of blood glucose levels and administration of insulin and injectable non–insulin-related medications. The lancets, needles, and syringes used for DM management are categorized as medical sharps. Improperly discarded medical sharps can cause needlestick injuries in unsuspecting individuals and thereby pose a considerable public health risk. Release of these items into the environment will likely increase with the rising worldwide prevalence of DM, and a public safety crisis will emerge if proper disposal measures are not emphasized. This article reviews the literature from various geopolitical regions and describes how a substantial number of patients with DM improperly discard their sharps. Data support the need to develop multifaceted and innovative approaches to reduce risk associated with improper disposal of DM-related medical sharps into local communities.

Item does not contain fulltext Measurement and production of traditional prosthetic sockets are time-consuming, labor-intensive, and highly dependent on the personnel involved. An alternative way to make prostheses is using computer-aided design (CAD) and computer-aided manufacturing (CAM). Fused Filament Fabrication (FFF) may be an alternative to make low-cost prosthetic sockets. This study investigates the tensile properties of potential printing materials suitable for FFF according to ISO527 (Standard Test Method for Tensile Properties of Plastics). To ensure that FFF-printed sockets are safe for patient usage, the structural integrity of the 3D-printed prosthesis will be investigated according to ISO10328 (International Standard Structural Testing of Lower Limb Prostheses). Tough PLA was the most suitable print material according to ISO 527 testing. The Tough PLA printed socket completed 2.27 million cycles and a static test target value of 4025 N. Future research remains necessary to continue testing new potential materials, improve print settings, and improve the socket design for the production of FFF-printed transtibial prosthetic sockets. FFF using Tough PLA can be used to create transtibial prostheses that almost comply with the International Standard for Structural Testing of Lower Limb Prostheses.

Background We investigated clinical equipoise across surgical members of the British Elbow and Shoulder Society (BESS) in relation to rehabilitation following rotator cuff repair. Method An online survey explored clinical equipoise regarding early patient-directed versus standard rehabilitation after rotator cuff repair to inform the design of a national randomised controlled trial (RCT). It described different clinical scenarios relating to patient age, tear size, location and whether other patient-related and intra-operative factors would influence equipoise. Results 76 surgeons completed the survey. 81% agreed/ strongly agreed that early mobilisation might benefit recovery; 57% were neutral/ disagreed that this approach risks re-tear. 87% agreed/ strongly agreed that there is clinical uncertainty about the effectiveness of different approaches to rehabilitation. As age of the patient and tear size increased, the proportion of respondents who would agree to recruit and accept the outcome of randomisation reduced, and this was compounded if subscapularis was torn. Other factors that influenced equipoise were diabetes and non-secure repair. Conclusion Surgical members of BESS recognise uncertainty about the effectiveness of different approaches to rehabilitation following rotator cuff repair. We identified a range of factors that influence clinical equipoise that will be considered in the design of a new RCT.

Objective Intraarticular (IA) administration of platelet-rich plasma (PRP) has been proposed as a new strategy to halt osteoarthritis (OA) progression. In patients with severe OA, its potential is limited because it is unable to reach the subchondral bone, so a new strategy is needed, and intraosseous (IO) infiltration has been suggested. The purpose is to assess the impact of IA together with IO infiltration of plasma rich in growth factors (PRGF) in serum hyaluronic acid (HA) and type II collagen cleavage neoepitope (C2C) levels. Design A total of 32 rabbits were included in the study and randomly divided into 2 groups: control and treatment. A 4-mm chondral defect was created in the medial femoral condyle and IA followed by IO infiltration were performed. Serum C2C and HA levels were measured using enzyme-linked immunosorbent assay (ELISA) tests before infiltration and 28, 56, and 84 days post-infiltration. Results Significant lower C2C serum levels were obtained in treatment group (IA + IO infiltration of PRGF) at 84 days post-infiltration than in control group (IA infiltration of PRGF + IO infiltration of saline solution), while no significant differences between groups were reported at any other study times. Regarding HA, at 56 days post-infiltration, greater significant levels were seen in the treatment group. However, at 84 days post-infiltration, no significant differences were obtained, although lower levels were reported in the treatment group. Conclusions Despite inconclusive, the results suggest that the combination of IA and IO infiltration with PRGF may enhance cartilage and subchondral bone regeneration, but further studies are needed.

As of February 2, 2021, the USA has 26,431,799 reported COVID-19 cases with 446,744 deaths. A high mortality rate (15%–40%) was reported among hospitalized patients with COVID-19 during the first wave of the pandemic. However, data regarding variation in COVID-19-related mortality and severity of illness among hospitalized patients with COVID-19 are heterogeneous. In this retrospective single-center study, we aimed to investigate the demographic characteristics, clinical presentations, disease severity, clinical outcomes, and in-hospital mortality of hospitalized patients with COVID-19 during the second wave of the pandemic. Adults with reverse transcription-PCR-confirmed SARS-CoV-2 infection were included. In-hospital mortality due to COVID-19 was the primary outcome, and intensive care unit admission, acute kidney injury, acute respiratory distress syndrome, respiratory failure requiring intubation, and septic shock were the secondary outcomes. A total of 101 adult patients were hospitalized with COVID-19 during the second wave study period. Of 101 patients, 8 were intubated and 6 died. The median duration of hospital stay was 6 days. Patients in the second wave were more likely to receive dexamethasone and remdesivir and less likely to require invasive mechanical ventilation. In-hospital mortality during the second wave was lower (5.9%) compared with the first wave (15.5%). At the last follow-up date, 86.1% were discharged alive from the hospital, 5.9% died and 7.9% were still in the hospital. Multivariate logistic regression showed higher odds of mortality were associated with higher age and elevated lactate dehydrogenase peak.

Purpose: Bleeding is the most dreadful and distressing complication of percutaneous nephrolithotomy, which can cause significant morbidity. Intravenous use of tranexamic acid to reduce bleeding complication is widely established. Our aim is to compare the result between the two groups using tranexamic acid intravenous and in irrigation solution. Materials and methods: A total of 160 patients were enrolled in this study. Patients were randomly allocated to two groups. Group 1 received 0.1% tranexamic acid solution (1000 mg in 1 L of irrigation solution (normal saline)). Group 2 received 1 g tranexamic acid intravenously in intraoperative period. Results: The mean estimated fall in haematocrit, mean estimated total blood loss and mean operative time in tranexamic acid irrigation group is significantly less compared to intravenous tranexamic acid group. No significant difference was found with regards to stone clearance. Conclusion: We found that tranexamic acid irrigation was safe and associated with reduced blood loss as compared to intravenous tranexamic acid.

The goal of human-centered insulin pen design is to relieve the treatment burden of a chronic condition and help affected individuals to feel free of disease. The patient as well as their entire ecosystem should be considered. At Novo Nordisk A/S, we believe that embedding human-centered design at the heart of our development processes is best achieved with multidisciplinary experts in-house to work alongside product development teams and, importantly, the end user. Novo Nordisk introduced the first commercially available insulin pen in 1985 and has continued to develop reusable/durable and prefilled insulin pens to meet different patient needs, through to the latest NovoPen 6 and NovoPen Echo Plus with SMART technology. Human-centered design is essential for delivering meaningful and practical solutions for individuals with diabetes.

The role of thrombolysis in submassive pulmonary embolism (PE) is controversial due to the high risk of hemorrhage. This study aimed to evaluate the role of half-dose tissue-type plasminogen activator (rt-PA) in preventing death/hemodynamic decompensation in submassive (intermediate-risk) PE without increasing the risk of bleeding. In a prospective, non-randomized, open-label, single-center trial, we compared 50 mg rt-PA plus low molecular weight heparin (LMWH) with LMWH in submassive (intermediate-risk) PE. Eligible cases had confirmed pulmonary hypertension on echocardiography, and/or right ventricular cavity expansion and/or interventricular septal deviation on echocardiography, and/or right to left ventricular ratio equal to or greater than 0.9 mm on CT angiography. The primary outcome was death or hemodynamic decompensation within 7 and 30 days after treatment was given. The primary safety outcome was major extracranial bleeding or hemorrhagic stroke within 7 days. Seventy-six patients were included in the study. Total death/hemodynamic decompensation in the first 7 and 30 days was significantly less in the half-dose rt-PA group than in the LMWH group (p=0.028 and p=0.009, respectively). No significant differences were found between the two groups in terms of recurrent embolism and pulmonary hypertension at 6-month follow-up (p=1.000 and p=0.778). There was no intracranial hemorrhage in any of the patients. There were no statistically significant differences between the two groups in terms of major or minor bleeding complications. This trial showed half-dose rt-PA treatment in submassive (intermediate-risk) PE prevented death/hemodynamic decompensation in the first 7-day and 30-day period compared with LMWH treatment without increasing the risk of bleeding.

Objectives We used single-center data to evaluate the long-term outcome of percutaneous transluminal angioplasty (PTA) for pediatric renovascular hypertension (RVH) and to analyze the factors that influence effectiveness. Methods We retrospectively evaluated 33 pediatric RVH patients (18 boys; mean age: 9.1 ± 4 years, range: 2–16) who underwent PTA from January 2007 to December 2019. 15 patients had Takayasu arteritis (TA) and 18 were non-TA. The median follow-up from the initial PTA was 69 months (range: 12–157; IQR: 25.5–89). Results The technical success rate of 52 PTA procedures was 90.4% in 33 children. Renal artery stents were implanted in two patients, external guidewires were used in two patients, and a drug-coated balloon was used in only one patient. The overall effective rate of PTA was 63.6%, including cured 39.4% and improved 24.2%, at the end of follow-up. Overall clinical outcomes were not statistically different between the TA and non-TA groups ( p = 0.316), nor were cure rates ( p = 0.072). 15 patients received reintervention due to restenosis after the first successful PTA; the interval was 2–56 months (median: 12 months). Four patients received reintervention due to a failed PTA. A total of four patients received open surgery. Binary logistics regression analysis showed that stenosis length and residual stenosis rate were strongly correlated with effective PTA ( p = 0.045, p = 0.044). Conclusions As a primary treatment for pediatric RVH, PTA can achieve satisfactory results, which are influenced by lesion length and residual stenosis rate.

BackgroundIntraoperative parathyroid hormone (iPTH) testing is often used to confirm successful removal of hypersecreting parathyroid glands during parathyroidectomy. Unfortunately, the iPTH test can be a time-consuming and highly variable process that occurs while the patient is under anesthesia. We set out to improve iPTH lab efficiency and variability.MethodsWe performed a retrospective review of 85 patients who underwent parathyroidectomy at our institution from October 2017 to October 2019. Each step of the iPTH lab reporting process was recorded and analyzed. Three simulations were performed of the entire process. We then established interventions to modify inefficiencies in the process and studied 21 patients who underwent parathyroidectomy at our institution from November 2019 to March 2020.ResultsTwenty-five minutes of time inherent to the process were identified. Four critical steps were identified as modifiable steps in the process: 1. Operating room (OR) blood draw ---> lab receipt. 2. Lab receipt ---> placement on centrifuge. 3. Removal from centrifuge ---> placement on PTH machine. 4. PTH machine result ---> OR verbal report. We improved iPTH lab efficiency by 19%, decreasing the average lab result from 45 to 36 minutes ( P = .001). We improved iPTH lab variability by 62%, decreasing the standard deviation from 21 to 8 minutes ( P = .001).DiscussionUtilizing a team-based approach to identify and expedite critical steps in the iPTH lab process can make a significant improvement in iPTH lab efficiency, improving patient care by decreasing total anesthesia time.

Purpose To evaluate the outcomes and complications of scleral buckle surgery alone or combined with pneumatic retinopexy (pneumatic buckle) for the treatment of primary rhegmatogenous retinal detachment. Design Retrospective chart review. Participants Two hundred thirteen patients with rhegmatogenous retinal detachment of whom 101 underwent primary scleral buckle surgery at Rabin Medical Center in 2005–2015 (SB group) and 112 underwent pneumatic buckle surgery at Royal Alexandra Hospital in 2013–2015 (PB group). Methods All patients were followed for ≥12 months. Data on clinical and surgical parameters, outcome, and complications were collected from the medical files. Main Outcome Measures Best corrected visual acuity and anatomical outcomes. Results At 12 months, average best corrected visual acuity was 0.3 logMar in the SB group and 0.42 logMar in the PB group ( P Conclusion Scleral buckle surgery alone is efficient for the treatment of rhegmatogenous retinal detachment. Its combination with pneumatic retinopexy usually has no significant added value in terms of anatomical reattachment rate. Outcomes of Pneumatic buckling vs Scleral Buckling for RRD

Purpose To describe features of uveitis-glaucoma-hyphema (UGH) syndrome, using Anterior Segment-Optical Coherence Tomography (AS-OCT) and Ultrasound Biomicroscopy (UBM) and to evaluate the diagnostic role of AS-OCT as an imaging technique alternative to UBM. Design Retrospective case series. Methods Four eyes of 4 patients with UGH syndrome were analyzed. All patients reported previous uncomplicated cataract surgery with in-the-bag implantation of single-piece-intraocular lens (IOL). They underwent at presentation complete ophthalmological examination and imaging with slit-lamp anterior segment photographs, UBM and AS-OCT. Results Although AS-OCT did not allow to visualize the structures behind the iris, it displayed a contact between IOL (plate and/or haptics) and iris and IOL tilting in 3 out of 4 eyes. AS-OCT directly detected the cause of UGH syndrome in one eye, 2 eyes required some expedients to display the iris chafing, like scans in mydriasis and/or patient's gaze direction change. AS-OCT did not allow to appreciate the IOL-iris contact (showed by UBM technique) only in one eye, probably due to the change of patient position from supine to sitting, and consequent anteriorization of iris diaphragm. Furthermore AS-OCT showed fine details, as capsular bag collapse and indirect signs of haptic malposition in 3 out of 4 eyes. Conclusion AS-OCT is a non-invasive technique that allows to determine IOL position and IOL-uveal contact in selected cases of UGH syndrome. Considering AS-OCT and UBM advantages and limitations, AS-OCT should be used as first imaging modality when clinical diagnosis is uncertain. When UGH diagnosis cannot be verified using AS-OCT, UBM should be performed.

Progestogen administration is required to oppose naturally produced or administered estrogens to provide endometrial protection. Within HRT regimens, this should be delivered for at least the same duration as that produced during the luteal phase of the monthly cycle and in the recommended doses to protect against the risk of endometrial hyperplasia and endometrial cancer. This includes progestogens administered for 12–14 days a month in sequential regimens and continuous daily intake in continuous combined HRT regimens. Shorter durations and lower doses of progestogen intake are likely to be associated with an increased risk of breakthrough bleeding, endometrial hyperplasia, and endometrial cancer.

Objective To investigate the physiological profile of pro-inflammatory and anti-inflammatory cytokines in tears produced by epithelial cells under the effect of endogenous and exogenous biological factors. Knowing the physiological cytokine profile in tears with its biological characteristics including sex- and age-specific effects is fundamental when tears are analyzed for diagnostic or prognostic purposes in eye diseases. Methods Tear samples were collected from right eye of 45 healthy volunteers (24 males, 21 females) by 5 μl microcapillary tube. Cytokines interleukin 1β, interleukin 10, interleukin 4, interferon gamma, macrophage migration inhibitory factor, and vascular endothelial growth factor were quantified by multiplex Bio-Plex system. Results The production of macrophage migration inhibitory factor cytokine by epithelial cells on the ocular surface is higher in males compared to females ( p = 0.05); actually, most of female tear samples present with undetectable macrophage migration inhibitory factor levels. Our results show the negative correlations between the age and concentrations of interleukin 4 ( p < 0.01) and interferon gamma ( p < 0.01) in tears, respectively, and positive associations of vascular endothelial growth factor levels with the age above 45 years ( p < 0.05). Conclusions Data in this study indicate that age and sex may affect the physiological levels of cytokines in tears. Consequently, the impacts of biological factors need to be recognized and taken into consideration before the levels of cytokines in patients’ tears are analyzed for medical reasons. Concentrations of interleukin 1β and interleukin 10 cytokines, however, are very low in healthy tears and do not seem to be influenced by studied biological factors; therefore, they meet the requirements for analytes suitable for medical diagnostic and prognostic purposes.

The aim of this study was to compare the prognosis of patients according to diabetes status, during a 1-year follow-up after hospital admission for lower extremity artery disease, in the prospective COPART (COhorte de Patients ARTériopathes) registry. Inclusion criteria were intermittent claudication, ischemic rest pain, tissue loss, or acute limb ischemia, with radiological and hemodynamic confirmation. Among 2494 patients, 1235 (49.5%) had diabetes. Incidence rates for major adverse cardiovascular events (MACE) were 18.0/100 person-years (95% confidence interval [CI], 15.4–21.0) for the diabetes group and 11.1/100 person-years (95% CI, 9.2–13.4) for the non-diabetes group. Incidence rates of all-cause mortality were 29.8/100 person-years (95% CI, 26.5–33.4) for the diabetes group and 19.7/100 person-years (95% CI, 17.2–22.7) for the non-diabetes group. Incidence rates of major limb amputation were 24.2/100 person-years (95% CI, 21.1–27.8) for the diabetes group and 11.6/100 person-years (95% CI, 9.6–14.0) for the non-diabetes group. Diabetes was associated with MACE, adjusted hazard ratio 1.60 (95% CI, 1.16–2.22), and all-cause mortality, unadjusted HR 1.49 (95% CI, 1.24–1.78). In the multivariate analysis, diabetes was no longer associated with major amputation, adjusted HR 1.15 (95% CI, .87–1.51). Patients hospitalized for LEAD with diabetes had a higher risk of MACE than those without diabetes.

Background: Thus far, the clinical results of anterior cruciate ligament (ACL) reconstruction have been observed to be comparable between young and older patients. In contrast, age-related changes in the structural and mechanical properties of tendons used for autografts have been described. However, age-related changes associated with graft maturation remain poorly understood. Hypotheses: The hypotheses of this study were that (1) clinical outcomes after ACL reconstruction would be comparable between younger and relatively older patients and (2) younger patients would show lower signal intensity changes on magnetic resonance imaging scans indicative of graft maturation that would be better than that in relatively older patients. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively evaluated 236 patients who underwent double-bundle ACL reconstruction via the outside-in technique using hamstring autograft between January 2012 and December 2015. The patients were categorized by age into 3 groups: Results: The SIR of both bundles increased from 3 months to 12 months and decreased by 24 months, showing the same tendency in all groups. No significant difference was found in the SIR among the 3 groups at any time point ( P > .05). The IKDC score was significantly lower in the ≥40-year group than in the Conclusion: Patients aged ≥40 years exhibited lower IKDC scores compared with younger patients, although the results of graft maturation were comparable.

Purpose: The calcium score is a measure of vessel wall calcification and has clinical applications when studied in different vascular beds. The presence of vascular calcification in the arteries of the lower limbs is very common in patients with peripheral arterial disease; however, its relationship with the postoperative outcomes in patients undergoing lower limb revascularization is still poorly studied. The aim of this study is to evaluate association between the calcium score of lower limbs and the postoperative outcomes in patients with peripheral arterial disease undergoing revascularization procedures. Methodology: We retrospectively analyzed 88 lower limb revascularization procedures in 72 patients with critical limb ischemia who had enhanced computed tomography for preoperative evaluation. The calcium score was calculated, from the angiographic phase of preoperative computed tomography, in the segments of the aorta, iliac, femoropopliteal, and infrapopliteal. It was also calculated the calcium score of the operated limb, and the total calcium score using a standardized method. The outcomes evaluated were the occurrence of acute myocardial infarction, amputation, patency, technical success, and death from any cause. Patients were followed up through a 12 month period. Results: Among the 88 procedures performed, 31 (43.1%) lesions were classified as Trans-Atlantic Inter-Society Consensus Document II D. There were 66 (75%) endovascular procedures, 16 (18.2%) open surgery, and 6 (6.8%) hybrid interventions. No statistically significant relationship was found between the calcium score of the segments (aorta, iliac, femoropopliteal, infrapopliteal, the operated limb, and total calcium score) and the outcomes of acute myocardial infarction, amputation, patency, and technical success in any of the periods analyzed. The calcium score of the operated limb was higher in patients who died within 30 days and 6 months (6571 vs 2590.6; p=0.026) and (5227.8 vs 2335.3; p=0.036). Conclusion: A standardized calcium score calculation method with the angiographic phase of the computed tomography is feasible and reproducible. Higher values of the calcifications of the operated limb are related to a greater chance of death in the postoperative period. The calcium score of the operated limb can be considered as a marker of clinical severity and prognosis in this group of patients

Background: Pediatric cardiothoracic surgery has evolved over the last several decades with shorter bypass times and less need for hypothermic arrest. Diuretics have been commonly used in the post-operative period with no guidelines on duration following cardiopulmonary bypass. As a result, we conducted a single-center quality improvement project to reduce overuse of diuretics in post-operative patients without causing an increase in complications. We devised an early diuretic wean protocol that was implemented upon patient discharge. Methods: All patients who underwent uncomplicated congenital heart surgery after November 2018 were considered for the protocol. We defined an early diuretic wean protocol with a total duration of ten days of single diuretic therapy following hospital discharge. Patients were evaluated in clinic two weeks following discharge, after completion of diuretic therapy, to assess for clinical symptoms and development of effusions. Results: Retrospective pre-protocol data found the average duration a patient was on diuretics was 32 days following hospital discharge from uncomplicated congenital heart surgery. Following implementation of the protocol, there was a decrease in the total duration to 14 days, demonstrating a 56% decrease. With this practice change, there was no notable increase in adverse events. Conclusions: With implementation of the protocol, practice variability was minimized and the average post-operative diuretic duration was decreased without an increase in pleural and/or pericardial effusions or readmissiosn rates. Future directions and ongoing changes include expanding to a multicenter quality improvement collaborative focusing on decreasing the average duration of furosemide to less than five days after hospital discharge.

Objectives: The submental island flap is a dependable workhorse in head and neck reconstruction. However, the viability of this flap has not been established for oral cavity reconstruction when a contralateral neck dissection has already been performed in an earlier surgical setting. The aim of this study is to highlight technical considerations and outcomes of this approach with a small case series. Methods: Three cases of oral cavity reconstruction with a submental island flap elevated in the context of a prior contralateral neck dissection are presented. Results: In all cases, a doppler was used to identify the maintenance of the submental perforator in the neck opposite the previous neck dissection. In 2 cases, level IA was included within the dissection field of the previous neck dissection. Additionally, the old neck scar was included within the skin paddle of the submental island flap in 2 cases. In all cases, excellent healing of the flap was observed without partial or complete loss. Conclusions: The submental island flap appears to be a reliable reconstruction when a previous contralateral neck dissection has been performed, even when level IA was included in the prior dissection.

Objective: Post-traumatic stress disorder following injuries unrelated to mass casualty events has received little research attention in New Zealand. Internationally, most studies investigating predictors of post-injury post-traumatic stress disorder focus on hospitalised patients although most survivors are not hospitalised. We compared the prevalence and predictors of symptoms suggestive of post-traumatic stress disorder 12 months following injury among hospitalised and non-hospitalised entitlement claimants in New Zealand’s Accident Compensation Corporation. This government-funded universal no-fault insurance scheme replaced tort-based compensation for injuries in 1974 since when civil litigation (which can bias post-traumatic stress disorder estimates) has been rare. Methods: A total of 2220 Accident Compensation Corporation claimants aged 18–64 years recruited to the Prospective Outcomes of Injury Study were interviewed at 12 months post-injury to identify symptoms suggestive of post-traumatic stress disorder using the Impact of Events Scale. Multivariable models examined the extent to which baseline sociodemographic, injury, health status and service interaction factors predicted the risk of post-traumatic stress disorder symptoms among hospitalised and non-hospitalised groups. Results: Symptoms suggestive of post-traumatic stress disorder were reported by 17% of hospitalised and 12% of non-hospitalised participants. Perceived threat to life at the time of the injury doubled this risk among hospitalised (adjusted relative risk: 2.0; 95% confidence interval: 1.2–3.2) and non-hospitalised (relative risk: 1.8; 95% confidence interval: 1.2–2.8) participants. Among hospitalised participants, other predictors included female gender, Pacific and ‘other’ minority ethnic groups, pre-injury depressive symptoms, financial insecurity and perceived inadequacies in healthcare interactions, specifically information and time to discuss problems. Among non-hospitalised survivors, predictors included smoking, hazardous drinking, assault and poor expectations of recovery. Conclusion: One in six hospitalised and one in eight non-hospitalised people reported post-traumatic stress disorder symptoms 12 months following injury. Perceived threat to life was a strong predictor of this risk in both groups. Identifying early predictors of post-traumatic stress disorder, regardless of whether the injury required hospitalisation, could help target tailored interventions that can reduce longer-term psychosocial morbidity.

Medical and dental records of Veterinary Dental Specialties and Oral Surgery were searched to identify dogs that received full metal prosthodontic crowns on canine teeth, using a feather or knife edge preparation between 2005 and 2017. A total of 160 teeth in 84 dogs were included in the study. Current follow-up by telephone, electronic mail, or electronic messaging was conducted, in addition to thorough record review for in-person recheck examinations. Treatment was considered successful if the prosthodontic crown was in place and no further or additional injury to the tooth had occurred at the time of reexamination, owner contact, or patient death. Tooth fracture apical to the prosthodontic crown occurred in 2 (1.25%) cases, bond failure between the tooth and the cement or the cement and the crown occurred in a single case (0.625%), and one metal crown required replacement after 3 years due to wear (0.625%), for an overall failure rate of 2.5%. These results suggest that feather preparation of the margin is at least as, if not more, successful as the more commonly accepted and performed chamfer margin, and thus is a successful, practical and durable option for prosthodontic crown treatment in dog canine teeth.

Perioperative staff are frequently exposed to surgical smoke or plume created by using heat-generating devices like diathermy and lasers. This is a concern due to mounting evidence that this exposure can be harmful with no safe level of exposure yet identified. First, I briefly summarise the problem posed by surgical smoke exposure and highlight that many healthcare organisations are not sufficiently satisfying their legal and ethical responsibilities to protect their staff from potential harm. Second, I explore the ethical case for compulsory smoke evacuation systems using the principlist framework and its four ethical principles – autonomy, beneficence, nonmaleficence, and justice. I then consider some objections and argue that surgical smoke evacuation systems – when indicated – should be made compulsory.

Background Finite element analysis has suggested that stemless implants may theoretically decrease stress shielding. The purpose of this study was to assess the radiographic proximal humeral bone adaptations seen following stemless anatomic total shoulder arthroplasty. Methods A retrospective review of 152 prospectively followed stemless total shoulder arthroplasty utilizing a single implant design was performed. Anteroposterior and lateral radiographs were reviewed at standard time points. Stress shielding was graded as mild, moderate, and severe. The effect of stress shielding on clinical and functional outcomes was assessed. Also, the influence of subscapularis management on the occurrence of stress shielding was determined. Results At 2 years postoperatively, stress shielding was noted in 61 (41%) shoulders. A total of 11 (7%) shoulders demonstrated severe stress shielding with 6 occurring along the medial calcar. There was one instance of greater tuberosity resorption. At the final follow-up, no humeral implants were radiographically loose or migrated. There was no statistically significant difference in clinical and functional outcomes between shoulders with and without stress shielding. Patients undergoing a lesser tuberosity osteotomy had lower rates of stress shielding, which was statistically significant ( p = 0.021) Discussion Stress shielding does occur at higher rates than anticipated following stemless total shoulder arthroplasty, but was not associated with implant migration or failure at 2 years follow-up. Level of evidence IV, Case series.

The contribution of the tire-road slip of traction wheels to the total resistance opposing the motion of a light-duty commercial vehicle has been investigated through the simulation of several homologation and custom driving cycles. The calculation of the contribution of the tire slip losses was based on the estimation of the longitudinal tire slip, by means of Pacejka’s MF5.2 tire model. In this work, the computational steps required to evaluate this contribution were implemented in a previously developed fuel consumption simulation tool. Simulations were performed under several vehicle loading conditions and tire inflation pressures on traction and non-traction wheels, and considering different tire-road adherence conditions, in order to obtain a characterization of the tire slip losses over a wide range of working conditions. An analysis of the results shows that, although the contribution of tire slip losses to the total vehicle energy demand and fuel consumption may be relevant – especially under low-load, low adherence conditions – the sensitivity of the average on-cycle vehicle energy/fuel consumption to changes in the tire inflation pressure is only affected slightly by tire slip losses. Therefore, tire slip losses can be neglected in practice, when the aim of a simulation is to optimize the tire pressure to achieve average vehicle working conditions over a driving cycle.

Objective To study coronary interventions and mortality among patients with ST-elevated myocardial infarction (STEMI) who were admitted with septic shock. Methods Data from the national emergency department sample (NEDS) that constitutes 20% sample of hospital-owned emergency departments in the United States was analyzed for the septic shock related visits from 2016 to 2018. Septic shock was defined by the ICD codes. Results Out of 1 375 507 adult septic shock patients, 521 300 had a primary diagnosis of septic shock (mean age 67.41±15.67 years, 51.1% females) in the national emergency database for the years 2016 to 2018. Of these patients, 2768 (0.53%) had STEMI recorded during the hospitalization. Mortality rates for STEMI patients were higher than patients without STEMI (52.3% vs 23.5%). Mortality rates improved with PCI among STEMI patients (43.8% vs 56.2%). Coronary angiography was performed among 16% of patients of which percutaneous coronary intervention (PCI) rates were 7.7% among patients with STEMI septic shock. PCI numerically improved mortality, however, had no significant difference than patients without PCI on multivariate logistic regression and univariate logistic regression post coarsened exact matching of baseline characteristics among STEMI patients. Among the predictors, STEMI was a significant predictor of mortality in septic shock patients (OR 2.87, 95% CI 2.37-3.49; PConclusion STEMI complicating septic shock worsens mortality. PCI and coronary angiography numerically improved mortality, however, had no significant difference from patients without PCI. More research will be needed to improve mortality in such a critically ill subgroup of patients.

Background While ptosis is a well-known consequence of glaucoma surgery, some isolated case reports point to the possibility of upper eyelid retraction occurring after glaucoma surgery. This study aims to analyze the occurrence of ptosis and eyelid retraction after glaucoma surgery and to evaluate factors contributing to these palpebral fissure changes. Methods Cross-sectional study including 100 eyes of 100 patients that had undergone unilateral glaucoma surgery. Upper eyelid height in the operated eye was measured by digital photography and compared with the fellow, non-operated eye. The main outcome was to determine if ptosis or retraction occurred in the operated eye in comparison with the fellow eye. The secondary outcome was to determine if any variable was associated with ptosis or retraction. A clinically significant difference (either toward ptosis or retraction) was defined as a difference ≥1 mm between both eyes. Results Of 100 eyes included 81 (81%) showed no change in eyelid height (−0.133 mm ± 0.496), 11 (11%) showed ptosis (−1.348 mm ± 0.387) and 8 eyes (8%) showed retraction (1.705 ± 0.634). A statistically significant relation was found between ptosis and pseudoexfoliation glaucoma (p = 0.003). A trend toward lower postoperative IOP and higher conjunctival blebs was found in eyes with postoperative eyelid retraction. Conclusions Eyelid retraction was present in 8% of patients and ptosis in 11%. Patients with eyelid retraction showed around a 3 mmHg lower postoperative IOP than eyes without retraction. The presence of pseudoexfoliation may be a risk factor for this complication. A prospective study with a large number of patients would be required to confirm these results.

Objective To assess early maxillary dentoalveolar changes in children with unilateral cleft lip and palate (UCLP) up to 6 months after palatoplasty. Design Pilot study. Patients and Participants Eight children with UCLP at the age of 18 to 30 months, who were awaiting palatal repair, were included. Interventions All participants with repaired lip were scheduled for palatal repair between 18 and 24 months by Bardach's technique. Main Outcome Measure(s) Arch widths, arch depths, and arch perimeter was measured on 32 dental casts of 8 participants at 4 time points: just prior to palatal repair (T1), 1 month (T2), 3 months (T3), and 6 months (T4) after palatal repair. Manual method using digital vernier caliper (Zhart, India) was used for model analysis. Intraexaminer reliability was also assessed. Results Only one examiner assessed all the dental casts after blinding. There was a significant decrease in the intercanine width (29.75 ± 1.98 mm at T1 to 26.42 ± 1.67 mm at T4; P Conclusions There was growth restriction in the anterior part of the palate, whereas the posterior region continued to grow after palatal repair. These changes were observable even in the early months after palatoplasty.

We retrospectively compared the results of volar plating and dynamic external fixation for acute unstable dorsal fracture-dislocations of the proximal interphalangeal joint with a depressed fragment. We treated 31 patients (31 fingers), 12 with volar buttress plating and 19 with dynamic external fixation. Follow-up averaged 35 and 40 months in the two groups, with a minimal 6-month follow-up. Average active flexion of the proximal interphalangeal joint was 95° after plate fixation and 87° after external fixation, with an active extension lag of –6° and –9°, respectively. Active flexion at the distal interphalangeal joint averaged 67° in the plate group and 58° in the external fixation group, with active extension lags of 0° and –5°, respectively. We conclude that both methods can obtain a good range of motion at the proximal interphalangeal joint. A limitation of the extension of the distal interphalangeal joint occurred with dynamic external fixation but not with volar buttress plating. Level of evidence: IV

Objective Continuous renal replacement therapy (CRRT) is commonly used in critically ill, hemodynamically unstable patients with acute kidney injury (AKI). This procedure is resource intensive with reported high in-hospital mortality. We evaluated mortality with CRRT in our healthcare system and markers associated with decreased survival. Methods A retrospective cohort study collected data on patients 18 years or older, without prior history of end stage kidney disease (ESKD), who received CRRT in the intensive care units at one of three hospitals in our health system in Columbus, OH from July 1, 2016 to July 1, 2019. Data included demographics, presenting diagnosis, comorbidities, laboratory markers, and patient disposition. In-hospital mortality rates and sequential organ failure assessment (SOFA) scores were calculated. We then compared information between two groups (patients who died during hospitalization and survivors) using univariate comparisons and multivariate logistic regression models. Results In-hospital mortality was 56.8% (95%CI: 53.4–60.1) among patients who received CRRT. Mean SOFA scores did not differ between survival and mortality groups. The odds for in-patient mortality were increased for patients age ≥60 (OR = 1.74, 95%CI: 1.23-2.44), first bilirubin >2 mg/dL (OR = 1.73, 95%CI: 1.12-2.69), first creatinine < 2 mg/dL (OR = 1.57, 95%CI: 1.04–2.37), first lactate > 2 mmol/L (OR = 2.08, 95%CI: 1.43-3.04). The odds for in-patient mortality were decreased for patients with cardiogenic shock (OR = .32, 95%CI: .17-.58) and hemorrhagic shock (OR = .29, 95%CI: .13-.63). Conclusions We report in-hospital mortality rates of 56.8% with CRRT. Unlike prior studies, higher mean SOFA scores were not predictive of higher in-hospital mortality in patients utilizing CRRT.

Whole-exome sequencing studies have recently identified novel genes implicated in normal- or low-GGT pediatric cholestasis including ubiquitin-specific peptidase 53 ( USP53). We identified novel biallelic mutations in the USP53 gene in a 7-month-old infant with pruritus and progressive intrahepatic cholestasis. His liver biopsy showed portal and perivenular fibrosis with bland bilirubinostasis. His parents were asymptomatic heterozygous for the same mutation. He is currently on vitamin supplements and cholestyramine and his family has also been counseled for liver transplantation. Our report confirms that patients with biallelic mutation in USP53 develop cholestatic liver disease.

Background of the study: Instrumental activities of daily living (IADL) are activities that are needed to live an independent life. Psychotic disorders are associated with deficits in everyday functioning, causing impairment/disability in activities of daily living. Activities play a crucial role to measure functional health or disability. People with Schizophrenia often present difficulties in social and occupational reintegration that may be associated with problems in performing daily activities, including independent living, education, working, and socializing. Activities of daily living and instrumental activities of daily living (life skills training) including leisure and social skills training intended to reintegrate the patient into the community to lead an everyday life. Aim: The aim of this review was to identify the effect of skill-based interventions on independent functioning in persons with Schizophrenia. Methods: The authors conducted database searches of Google Scholar, PubMed, Science Direct, ProQuest, EBSCO from 1st January 1992 to 31st December 2020. The researcher extracted data, and the quality of included studies was rated by two authors independently. We used the Cochrane Risk of Bias (ROB) tool for assessing the quality of selected studies. The search identified nine studies that met the inclusion criteria with 655 participants. The outcome measure was independent functioning skills. Results: The interventions in the review were multifaceted with different combinations of psychoeducation, cognitive-behavioral methods, training in social skills, and IADL. The interventions resulted in significant improvement in functioning skills and reduction in relapse rates. Conclusion: Results of this review have revealed moderate to strong evidence for skills training, either behavioral or social skills to improve social and independent functioning, reduce caregiver burden, and improve negative symptoms. The review also supported that interventions could be generalized across settings.

Background: The majority of youth with type 1 diabetes (T1D) fail to meet glycemic targets despite increasing continuous glucose monitoring (CGM) use. We therefore aimed to determine the proportion of caregivers who review recent glycemic trends (“retrospective review”) and make ensuant insulin adjustments based on this data (“retroactive insulin adjustments”). We additionally considered that fear of hypoglycemia and frequency of severe hypoglycemia would be associated with performing retrospective review. Methods: We conducted a cross-sectional survey of caregivers of youth with T1D, collecting demographics, diabetes technology usage, patterns of glucose data review/insulin dose self-adjustment, and Hypoglycemia Fear Survey (HFS). Results: Nineteen percent of eligible caregivers (191/1003) responded. Performing retrospective review was associated with younger child age (12.2 versus 15.4, P = .0001) and CGM use (92% versus 73%, P = .004), but was not associated with a significant improvement in child’s HbA1c (7.89 versus 8.04, P = .65). Retrospective reviewers had significantly higher HFS-behavior scores (31.9 versus 27.7, P = .0002), which remained significantly higher when adjusted for child’s age and CGM use ( P = .005). Linear regression identified a significant negative association between HbA1c (%) and number of retroactive insulin adjustments (0.24 percent lower mean HbA1c per additional adjustment made, P = .02). Conclusions: Retrospective glucose data review is associated with improved HbA1c when coupled with data-driven retroactive insulin adjustments. Barriers to data downloading existed even in this cohort of predominantly CGM-using T1D families.

Aims: Primary aim was to determine survival of a cemented acetabular component with bulk roof autograft with a minimum of 12 years follow-up. The secondary aim was to determine the clinical outcome. Methods: A cohort of 62 consecutive patients (74 hips) undergoing cemented total hip arthroplasty with acetabular bulk roof autograft for acetabular dysplasia were retrospectively identified. The group consisted of 57 female patients (67 hips) and 5 male patients (7 hips) with a mean age at operation of 45 years. No patient was lost to follow-up, however 9 patients died had during the study period. The Oxford Hip Score (OHS), Forgotten Joint Score (FJS), EuroQol 5-Dimensional Score (EQ-5D), Short Form (SF-12) physical score and patient satisfaction were used to assess clinical outcome for patients with a surviving prosthesis. Results: The median follow-up was 16.6 (13.4–19.1) years. 6 revisions were performed during the follow-up period, all of which were due to aseptic loosening of the acetabular component. The all-cause Kaplan Meier survival rate for the acetabular component was 99% at 10 years, 95% at 15 years and 83% at 20 years. Neither age, gender, femoral osteotomy or polyethylene (UHMW vs. cross-linked) were significant predictors of aseptic revision of the acetabular component. There were no case of graft resorption and all grafts were radiologically incorporated. 45 patients were available for functional assessment at a mean follow-up of 18.2 years. The mean OHS was 37.8, FJS was 55.7, EQ5D was 0.73, and SF-12 physical component was 43.2. No patient was dissatisfied, with 2 patients reporting a neutral satisfaction, 7 stating they were satisfied and the remaining 36 were very satisfied. Conclusions: A cemented acetabular component with bulk roof autograft for dysplasia offers excellent survival with good to excellent functional outcome with high patient satisfaction in the medium- to long-term.

Background Balloon microcatheters are widely used for endovascular treatment. However, no reports on direct coil embolization from dual-lumen balloon microcatheters are available in the literature. This report is the first description of direct coil embolization using this type of balloon microcatheter for looming bleeding emergencies. Methods This retrospective review demonstrates the indications and advantages of coil embolization from an inflated balloon catheter to reduce blood loss and simultaneously occlude bleeding. Results Five patients who underwent emergency endovascular treatment using coil embolization directly delivered from a dual-lumen balloon were identified. Etiologies included vertebro-vertebral arteriovenous fistula, ruptured vertebral artery dissecting aneurysm, vertebral artery injury during cervical spinal operation, and failed stent retrieval procedures for acute infarction. Complete hemostasis was achieved with all procedures. Conclusion Our experience demonstrates the feasibility of direct coil embolization by using a dual-lumen balloon to rapidly halt bleeding in some rare emergency situations, which may save lives.

Background Endoscopic sinus surgery is a well-established treatment for chronic rhinosinusitis in patients with cystic fibrosis, though its benefits seem to be limited to improving sinonasal symptoms rather than affecting lung function. Objective This study aims to identify clinical and demographic factors that may influence sinonasal and pulmonary outcomes after surgery. Methods This is a six-year retrospective analysis of adult cystic fibrosis patients who underwent endoscopic sinus surgery at a tertiary care center. 22-Item Sino-Nasal Outcomes Test scores and mean forced expiratory volume data at baseline and three to six months after surgery were analyzed using t-test and stepwise regression with the following covariates: age, gender, lung transplant, revision surgery, and pseudomonas on sinus culture. Results 119 surgeries were performed on 88 patients, with 69% on patients with transplant. The overall mean (Standard Deviation) improvement in 22-Item Sino-Nasal Outcomes Test score was 9.42 (18.15) for the entire cohort ( P Conclusion Although surgery was associated with a clinically and statistically significant improvement in sinonasal scores in cystic fibrosis patients, patients with pseudomonas may experience less benefit. Revision surgery and older age may be associated with less favorable pulmonary outcomes. Awareness of such variables may help when deciding which cystic fibrosis patients should undergo surgery.

This review gives a summary of the records of shoulder dislocation management throughout history until the point that anaesthetics were introduced and modern medicine improved dislocation management exponentially. A dislocation is a mechanical injury that has been managed in different ways throughout history. The shoulder reduction methods described in Hippocrates Corpus have been described and adjusted throughout history by later physicians. For example, in ancient Greek, Hippocrates considered the ambe, a device used to reduce the shoulder, to be the most powerful tool. However, Cooper, a physician in the 19th century, considered it to be the last resort due to substantial damage to the ribs and discomfort of the patient. This review demonstrates that there were many physicians that contributed to shoulder dislocation management. These physicians paved the way for modern shoulder dislocation treatment strategies.

Increased environmental pollution and unhealthy lifestyle are blamed for escalated chronic diseases. Exposure to aflatoxins was recently suggested to have a role in the increased incidence of type 2 diabetes mellitus. Diet modification and consumption of different functional food are now gaining attention, especially in diabetes management. This study investigates the effect of a diet containing barley microgreen against diabetes induced by streptozotocin with or without aflatoxin administration in rats. Barley microgreen was rich in 3′-Benzyloxy-5,6,7,4′-tetramethoxyflavone (48.8% of total) followed by 5β,7βH,10α-Eudesm-11-en-1α-ol (18.46%). Streptozotocin injection and/or aflatoxin administration significantly elevated glucose level, decreased insulin level, decreased β-cell function, deteriorated liver and kidney function parameters, and induced oxidative stress in the liver. Histopathology revealed irregular small-sized islets and decreased area % of insulin-positive beta cells in the pancreas, hepatic degeneration, nephropathy, and neuropathy in diabetic and/or aflatoxin administered rats compared to control. Barley microgreen diet fed to diabetic rats with or without aflatoxin alleviated all evaluated parameters. Barley microgreen diet also ameliorated the toxic effect of aflatoxin. In conclusion, exposure to aflatoxin aggravated diabetes and its complication. The incorporation of barley microgreen in the diet was able to control type 2 diabetes mellitus and the improved outcomes observed with barley microgreen treatments involved or occurred in conjunction with improved biomarkers of oxidative stress.

Gallbladder cancer (GBC) is an uncommon but very aggressive malignancy with poor prognosis. Concerns for oncological inferiority related to the technical difficulties in performing laparoscopic portal lymphadenectomy discourage many surgeons to undertake this operation minimally invasively. With wide application of robotic technology to solve limitations of conventional laparoscopy, we describe our initial outcomes of robotic central hepatectomy and portal lymphadenectomy for gallbladder carcinoma in 15 consecutive patients. Data were presented as median (mean ± SD). Patients were 70 (73 ± 10.9) years old with BMI of 26 (26 ± 3.6) kg/m2. Tumor size was 3(4 ± 1.9) cm. Operative duration was 222 (237 ± 85.7) minutes and estimated blood loss was 200 (222 ± 135.4) mL. There were no intraoperative complications and complete resection (R0) was obtained in nearly all patients. Postoperative complications were seen in two patients (bile leak (n = 1) and respiratory failure (n = 1)). Length of stay was 3 (4 ± 4.0) days without 30-day mortality. Robotic approach is safe and effective for the treatment of GBC.

Objectives The objective of this trial was to compare outcomes of electrocoagulation tuboplasty and continued medical therapy for treating persistent Eustachian tube dysfunction (ETD) with hypertrophic mucosa disease in the Eustachian tube (ET) orifice. Study Design Prospective, case-control trial. Material and Methods Patients with persistent ETD were recruited and allocated to electrocoagulation tuboplasty and continued medical therapy groups. The ETD questionnaire-7 (ETDQ-7) score and objective parameters were compared between the groups at 6 and 12 months. Results The proportion of patients with a decrease in ETDQ-7 scores was greater in the electrocoagulation group than in the medical therapy group at the 6-month follow-up (53.49% and 34.38%, respectively; p = .158), but the difference was not statistically significant. However, at the 12-month follow-up, there was a significantly higher proportion of patients with a decrease in ETDQ-7 scores in the electrocoagulation group (88.37% and 40.63%, respectively; p = .001). Additionally, a significant difference was observed between the groups in terms of the proportion of patients who improved 12 months after the treatment (tympanometry: 72.09% and 9.38%, respectively; p = .001; air-bone gap: 79.07% and 25.00%, respectively; p = .001; tympanic membrane status: 62.79% and 0.00%, respectively). In addition, the proportion of patients with improvements in the ET inflammation score was significantly different between the groups at 6-month (67.44% and 34.38%, respectively; p = .009) and 12-month (93.02% and 34.38%; p = .001) follow-ups. No device- or procedure-related serious adverse events were reported in any patients. Conclusions Electrocoagulation Eustachian tuboplasty appears to be a safe and feasible procedure for adult persistent ETD with hypertrophic mucosa disease in the ET orifice, and is superior to continued medical management alone. The improvements in ETDQ-7 and objective parameters persisted for 12 months.
