To enable standardization of management and facilitate improvements in outcome, a total of 53 multi-disciplinary experts in gastroenterology, surgery, medical oncology, radiation oncology, radiology, nuclear medicine, and pathology in Korea developed new recommendations that integrate the most up-to-date, evidence-based research findings and expert opinions. Recommendations were made on imaging diagnosis, endoscopic management, surgery, radiotherapy, palliative chemotherapy, and specific management procedures, including neoadjuvant treatment or adjuvant treatment for patients with resectable, borderline resectable, and locally advanced unresectable pancreatic cancer. This is the English version of the Korean clinical practice guideline for pancreatic cancer 2021. This guideline includes 20 clinical questions and 32 statements. This guideline represents the most standard guideline for the diagnosis and treatment of patients with pancreatic ductal adenocarcinoma in adults at this time in Korea. The authors believe that this guideline will provide useful and informative advice.α-Amylase and α-glucosidase are central enzymes involved in the digestion of carbohydrates. α-Glucosidase includes maltase-glucoamylase and sucrase-isomaltase. We have previously performed the kinetic analysis of the inhibitory effects of powdered or roasted Morus australis leaf extract and its component iminosugars, such as 1-deoxynojirimycin (1-DNJ), fagomine, and 2-O-α-d-galactopyranosyl deoxynojirimycin (GAL-DNJ) on the activity of maltase. In this study, we analyzed the inhibitory effects of the aforementioned compounds against α-amylase, glucoamylase, sucrase, and isomaltase. At pH 6.0 and 37 °C, each leaf extract sample inhibited glucoamylase, sucrase, and isomaltase but not α-amylase. 1-DNJ and fagomine showed weak α-amylase inhibitory activity while GAL-DNJ exhibited none. 1-DNJ showed a strong glucoamylase, sucrase, and isomaltase inhibitory potential. The inhibitory potential against these three enzymes was 18-500 and 1500-3000-fold higher in the case of 1-DNJ than that observed in the case of fagomine and GAL-DNJ, respectively. We also observed that the indigestible dextrin could considerably inhibit α-amylase. When the powdered M. australis leaf extract was blended with indigestible dextrin, the mixture inhibited α-amylase, as well as maltase, glucoamylase, sucrase, and isomaltase. These results suggest that the ingestion of the leaf extract blended with indigestible dextrin might have the potential to efficiently suppress the postprandial blood glucose level increase.Ethyl carbamate (EC), widely found in alcoholic beverages, has been revealed to be a probable carcinogen in humans. Urethanase (EC 3.5.1.75) is an effective enzyme for the degradation of EC; however, the previously identified urethanases exhibited insufficient acid and alcohol resistance. In this study, an enantioselective amidase (AmdA) screened from Agrobacterium tumefaciens d3 exhibited urethanase activity with excellent alcohol resistance. AmdA was first overexpressed in Escherichia coli; however, the recombinant protein was primarily located in inclusion bodies, and thus, co-expression of molecular chaperones was used. The activity of AmdA increased 3.1 fold to 307 U/L, and the specific activity of urethanase with C-terminal His-tags reached 0.62 U/mg after purification through a Ni-NTA column. Subsequently, the enzymatic properties and kinetic constants of AmdA were investigated. The optimum temperature for AmdA was 55 °C, it showed the highest activity at pH 7.5, and the Km was 0.964 mM. Moreover, after 1 h of heat treatment at 37 °C in a 5-20% (v/v) ethanol solution, the residual urethanase activity was higher than 91%, considerably more than that reported thus far.
As the burden of surgical care and the associated outreach trips to low- and middle-income countries increases, it is important to collect postoperative data to assess and improve the quality, safety, and efficacy of the care provided. In this pilot study, we aimed to evaluate the feasibility of short message service (SMS)-based mobile phone follow up to obtain patient-reported outcome measures after hand surgery during a surgical outreach trip to Vietnam.

Patients undergoing surgery during a week-long outreach trip to Hospital 175 in Ho Chi Minh City, Vietnam, who owned a mobile phone, were included in this study. Eight eligible patients elected to participate and were sent an SMS-based, Health Insurance Portability and Accountability Act-compliant text message with a link to a contextualized shortened Disabilities of the Arm, Shoulder and Hand questionnaire at 1 day, 1 week, 2 weeks, 4 weeks, and 12 weeks after the surgery. The patient characteristics and instrument completion rates were reported.

Thechnology can be scaled and contextualized based on location to ensure that patient care during outreach trips is safe and effective.
To identify the anatomic relationship between the distal extent of the A1 pulley and the distalmost insertion point of the palmar plate into the base of the proximal phalanx at a metaphyseal bony ridge, the "P1 peak" (P1P), which is a bony acoustic landmark easily identifiable on sonography of the finger.

We studied 48 fingers (no thumbs) from 12 fresh frozen cadavers with high-resolution ultrasound. A 20-gauge hypodermic needle was directed perpendicular to the long axis of the tendon sheath along a plumb line drawn at the level of the bony flare of the proximal metaphyseal-diaphyseal junction of the proximal phalanx, or the P1P, under high-resolution ultrasound guidance. Dissection was then performed, and the distance of the needle barrel and the actual distance of the P1P from the distal edge of the A1 pulley were recorded.

The study demonstrated that accurate placement of the needle within 1 mm of the actual P1P was possible using ultrasound guidance and that the P1P was within 1 mm of the distal edge of the actual A1 pulley in all specimens studied.

In all the specimens studied, we found that the P1P may be used as a clearly identifiable sonographic reference landmark to identify the distal extent of the A1 pulley.

Using the P1P landmark as a guide to judge the completeness of ultrasound-guided percutaneous trigger finger release may reduce the risks of incomplete distal release and inadvertent release of the A2 pulley.

The possible postoperative complications include residual radioulnar impingement and the development of a painful neuroma. In this report, a pedicled pronator quadratus flap interposition between the distal radius and ulna has been described. Additionally, various techniques to mitigate the development of symptomatic neuromas have been described.
Digit replantation can improve dexterity, functionality, patient satisfaction, and pain following amputation, but rates continue to fall nationally. This study aimed to describe the effects of travel time and distance as barriers to high-volume hospitals, identify geospatial inefficiencies in the presentation of patients to replantation care, and provide an optimal allocation model in which cases are redistributed to select centers to reduce geospatial redundancies and optimize outcomes.

We reviewed the California Office of Statewide Health Planning and Development hospital discharge database to identify cases of digital amputation and determine outcomes of replantation. Using residential zip codes, risk- and reliability-adjusted multivariable logistic regression was used to assess the relationship of hospital volume and travel time on replantation success. Geospatial analysis assessed the travel burden of patients as they presented for care, and optimal allocation modeling was used to create a model of c cases into high-quality centers can decrease travel times, increase annual volumes, and potentially improve replantation outcomes.

Economic/Decision Analysis III.
Economic/Decision Analysis III.In recent years, immunodeficiency condition has experienced a rise among children, who are at risk of invasive fungal infections (IFI) due to their health condition. Cancer, non-malignant hematological diseases, as primary immunodeficiencies, hematopoietic stem cell transplantation (HSCT), extreme prematurity, or critically ill condition in Pediatric Intensive Care Unit (PICU) are some immunosuppressive situations in children. The use of oncologic therapies, including immunotherapy and monoclonal antibodies, for the treatment of the aforementioned health conditions has led to an increase in morbidity and mortality rates of IFI in children. The underlying diseases and their management, comorbidities, the diagnostic tests used (both molecular and imaging), as well as the treatment used can be significantly different between adult patients and children admitted to PICU or with cancer. In pediatrics, the treatment of IFI is based primarily on pharmacokinetic studies performed in adults. In higher risk patients prophylaxis should be considered and, in the case of an IFI diagnosis, an antifungal treatment should be administered as early as possible, supported by the reversion of the immune dysfunction and surgery when appropriate.
To conduct a systematic review and meta-analysis to assess if the presence of an endodontic post may increase the fracture resistance of endodontically-treated maxillary premolars directly restored with composite.

A comprehensive systematic literature search according to the PRISMA statement was conducted to assess in vitro studies including endodontically-treated maxillary premolars, restored with different type of posts supporting direct composite reconstructions. Two groups of meta-analyses were performed using fixed effects model and additional Trial Sequential Analysis (TSA) was carried out. BAY-985 Moreover, risk of bias was conducted and quality of evidence for any performed meta-analysis was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE).

Twenty-four articles met the inclusion criteria and 13 studies also underwent quantitative evaluation. Fracture resistance of endodontically-treated premolars restored with fiber posts was significantly less than sound teeth (pared to equivalent teeth without post.The abundance of energy-dense and palatable diets in the modern food environment tightly contributes to the obesity pandemic. The reward circuit participates to the regulation of body homeostasis by integrating energy-related signals with neural substrates encoding cognitive and motivational components of feeding behaviors. Obesity and lipid-rich diets alter dopamine (DA) transmission leading to reward dysfunctions and food overconsumption. Recent reports indicate that dietary lipids can act, directly and indirectly, as functional modulators of the DA circuit. This raises the possibility that nutritional or genetic conditions affecting 'lipid sensing' mechanisms might lead to maladaptations of the DA system. Here, we discuss the most recent findings connecting dietary lipid sensing with DA signaling and its multimodal influence on circuits regulating food-reward processes.
