The use of medicinal leech therapy in pediatric cardiac surgery may be considered to minimize the consequences of advanced limb ischemia and venous congestion. However, this should be used with caution while patients are systemically anticoagulated during ECMO support. A directed review is presented here to assist in determining optimal application and potential course of therapy.

To evaluate the safety and effectiveness of remifentanil-based fast-track cardiac anesthesia (FTCA) combined with the postoperative serratus anterior plane block (SAPB) for transthoracic device closure of atrial septal defect (ASD) in pediatric patients.

A total of 70 children who underwent transthoracic device closure of ASDs from January 2018 to June 2020 were divided into two groups according to different anesthesia strategies administered, namely group F (fast-track anesthesia, n = 38) and group R (routine anesthesia, n = 32), and relevant clinical data were collected and analyzed.

There was no statistically significant difference between the two groups in general preoperative data, intraoperative hemodynamics, and FLACC score 1 h after extubation (p > .05). FLACC score of Group F was significantly lower than that of group R at 4, 8, 12, and 24 h after extubation (p < .05). The number of postoperative PCA press and the dose of PCA infusion in group F were lower than those in group R (p < .05). The mechanical ventilation duration, the length of intensive care unit stay in group F were statistically significantly lower than those in group R (p < .05).

Remifentanil-based FTCA combined with the postoperative SAPB for transthoracic device closure of ASD in pediatric patients could effectively reduce postoperative pain of the children.

The need for a better understanding of the underlying causes of suicidal behavior among BIPOC youth is critical. Cultural considerations were recommended over a decade ago to advance the study of youth suicide prevention and research. Without addressing the barriers to implementing these recommendations in limited-resourced settings, however, the mental health needs of BIPOC youth at risk for suicide will continue to go unmet. In this commentary, we outline structural barriers in research that perpetuate a cycle of exclusion wherein an understudied, though timely, research area faces undue burdens across the research cycle, which impedes the study of suicide risk among BIPOC youth.Autoimmune progesterone dermatitis (APD) is a rare skin disorder with varying presentations, resulting from hypersensitivity to endogenous progesterone during the luteal phase of the menstrual cycle. The diagnosis has been traditionally confirmed with intradermal progesterone testing (IPT) or intramuscular challenge with progesterone or its derivatives. We present a case of a 31-year-old woman with suspected APD who underwent IPT to progesterone. The patient's cyclical symptoms, positive skin reaction and symptoms following IPT were sufficient to make a diagnosis of APD. However, we also tested 10 healthy female controls without symptoms of APD, and found that 9 of these also developed positive skin reactions to intradermal progesterone at 15 min, 24 and 48 h, albeit to a lesser extent. Therefore, these results raise doubts about the validity of using IPT to make a diagnosis of APD. Further research on appropriate testing is needed.The majority of suicide decedents die on their initial attempt. To bring attention to suicide decedents without a suicide attempt history, the current study explored their demographic, clinical, and suicide-related characteristics. The data were derived from the Korea National Investigation of Suicide Victims Study, which assessed all suicide cases from 2013 to 2017 recorded in police investigation reports. ABT-199 We compared suicide decedents with and without a history of nonfatal attempts using the Korea Psychological Autopsy Checklist for Police Records (K-PAC). Out of 5228 cases included in our study, 3147 (60.2%) died on their first suicide attempt. Demographically, those who were male, older than 65, employed, and married/widowed were more likely to die on their initial attempt. Clinically, those who died on their initial attempt were more likely to have never been diagnosed with psychiatric disorders, whereas those who died on a repeated attempt were more likely to have been diagnosed with mood disorders. In terms of suicide-related factors, experiencing relationship problems and complaining about physical discomfort were associated with dying on an initial attempt. Depressed affect, self-harming behaviors, and talking about suicide or death were associated with repeated attempts.In aquatic detrital-based food webs, research suggests that autotroph-heterotroph microbial interactions exert bottom-up controls on energy and nutrient transfer. To address this emerging topic, we investigated microbial responses to nutrient and light treatments during Liriodendron tulipifera litter decomposition and fed litter to the caddisfly larvae Pycnopsyche sp. We measured litter-associated algal, fungal, and bacterial biomass and production. Microbes were also labeled with 14 C and 33 P to trace distinct microbial carbon (C) and phosphorus (P) supporting Pycnopsyche assimilation and incorporation (growth). Litter-associated algal and fungal production rates additively increased with higher nutrient and light availability. Incorporation of microbial P did not differ across diets, except for higher incorporation efficiency of slower-turnover P on low-nutrient, shaded litter. On average, Pycnopsyche assimilated fungal C more efficiently than bacterial or algal C, and Pycnopsyche incorporated bacterial C more efficiently than algal or fungal C. Due to high litter fungal biomass, fungi supported 89.6-93.1% of Pycnopsyche C growth, compared to 0.2% to 3.6% supported by bacteria or algae. Overall, Pycnopsyche incorporated the most C in high nutrient and shaded litter. Our findings affirm others' regarding autotroph-heterotroph microbial interactions and extend into the trophic transfer of microbial energy and nutrients through detrital food webs.Cell clarification represents a major challenge for the intensification through very high cell density in the production of biopharmaceuticals such as monoclonal antibodies (mAbs). The present report proposes a solution to this challenge in a streamlined process where cell clarification and mAb capture are performed in a single step using magnetic beads coupled with protein A. Capture of mAb from non-clarified CHO cell suspension showed promising results; however, it has not been demonstrated that it can handle the challenge of very high cell density as observed in intensified fed-batch cultures. The performances of magnetic bead-based mAb capture on non-clarified cell suspension from intensified fed-batch culture were studied. Capture from a culture at density larger than 100 × 106 cells/ml provided an adsorption efficiency of 99% and an overall yield of 93% with a logarithmic host cell protein (HCP) clearance of ≈2-3 and a resulting HCP concentration ≤≈5 ppm. These results show that direct capture from very high cell density cell suspension is possible without prior processing. This technology, which brings significant benefits in terms of operational cost reduction and performance improvements such as low HCP, can be a powerful tool alleviating the challenge of process intensification.Inverted papilloma is a rare sinonasal neoplasm. It can be locally invasive and potentially degenerate to a malignant tumor. We present a case report of a 36-year-old woman who was treated for nasal inverted papilloma for over 10 years and presented bilateral temporal bone, and pulmonary involvement. Several procedures were performed to completely remove the tumor. Even without evidence of malignant degeneration, the patient continued battling tumor recurrences. To the best of our knowledge, this report presents the first case of a multicentric inverted papilloma with nasal, bilateral temporal bone, and pulmonary metachronous localization. Laryngoscope, 2021.Constant flux virus filtration experiments were conducted to evaluate minute virus of mice retention behavior of four commercial virus filters for continuous bioprocessing applications. Fluxes chosen were guided by the Peclet number and the processing logistics as well as based on the filter characteristics. At the low flux condition of 5 LM - 2 H - 1 (LMH) when diffusive force dominates, a significant breakthrough was observed for all the filtrate fractions for the filtration of a low fouling monoclonal antibody for three of the four filters. When both diffusive and convective forces are equally important at 40 LMH, virus breakthrough in buffer chase was observed only in one of the four filters investigated. When convective force dominates at 60 LMH or above, a high degree of virus clearance was observed for all three parvovirus filters investigated. Our work shed light on virus clearance during constant flux virus filtration for future continuous biomanufacturing.Residence time distribution modeling of integrated perfusion to capture process can elucidate the impact of product quality excursions and filter fouling on monoclonal antibody production. In this case study, a glycosylation inhibitor and fluorescently labeled antibody are applied to the continuous process to study protein quality modulation, perfusion filter fouling, and unit operation hold times. The unit operations were modeled as continuous-stirred tank reactors and the residence time distribution of a small molecule glycan inhibitor and impact on glycosylation were characterized. A fluorescently labeled antibody was applied as a tracer molecule and confirmed the impact of packed cell volume and filter fouling. This study demonstrates how a biologics continuous process can be modeled and characterized through residence time distribution to ensure a robust, well-understood process.The integration of a bile drainage structure into engineered liver tissues is an important issue in the advancement of liver regenerative medicine. Primary biliary cells, which play a vital role in bile metabolite accumulation, are challenging to obtain in vitro because of their low density in the liver. In contrast, large amounts of purified hepatocytes can be easily acquired from rodents. The in vitro chemically induced liver progenitors (CLiPs) from primary mature hepatocytes offer a platform to produce biliary cells abundantly. Here, we generated a functional CLiP-derived tubular bile duct-like structure using the chemical conversion technology. We obtained an integrated tubule-hepatocyte tissue via the direct coculture of hepatocytes on the established tubular biliary-duct-like structure. This integrated tubule-hepatocyte tissue was able to transport the bile, as quantified by the cholyl-lysyl-fluorescein assay, which was not observed in the un-cocultured structure or in the biliary cell monolayer. Furthermore, this in vitro integrated tubule-hepatocyte tissue exhibited an upregulation of hepatic marker genes.
