The target compounds showed promising anti-MDR activities, suggesting they are potential leads for further development and in vivo studies.In this study, hematite nanotube (HNT) and tyramine-based advanced nano-drug carriers were developed for inhibiting the growth of Klebsiella pneumoniae (K. pneumoniae). The HNT was synthesized by following the Teflon line autoclaved assisted hydrothermal process and tyramine was incorporated on the surface of the HNT to fabricate the formulated nano-drug. The nano-drug was prepared by conjugating meropenem (MP) on the surface of Tyramine-HNT and characterized using different techniques, such as scanning electron microscopy (SEM), attenuated total reflection Fourier transform infrared (ATR-FTIR), etc. Furthermore, the drug-loading efficiency and loading capacity were measured using a UV-vis spectrometer. The pH, amount of Tyr, and HNT required for drug loading were optimized. A controlled and gradual manner of pH-sensitive release profiles was found after investigating the release profile of MP from the carrier drug. The antibacterial activity of MP@Tyramine-HNT and MP was compared through the agar disc diffusion method which indicates that antibacterial properties of antibiotics are enhanced after conjugating. Surprisingly, the MP@Tyramine-HNT exhibits a minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of K. pneumoniae lower than MP itself. These results indicate the nanocarrier can reduce the amount of MP dosed to eradicate K. pneumoniae.Discovered over four decades ago, transforming growth factor β (TGFβ) is a potent pleiotropic cytokine that has context-dependent effects on most cell types. It acts as a tumor suppressor in some cancers and/or supports tumor progression and metastasis through its effects on the tumor stroma and immune microenvironment. In TGFβ-responsive tumors it can promote invasion and metastasis through epithelial-mesenchymal transformation, the appearance of cancer stem cell features, and resistance to many drug classes, including checkpoint blockade immunotherapies. Here we consider the biological activities of TGFβ action on different cells of relevance toward improving immunotherapy outcomes for patients, with a focus on the adaptive immune system. We discuss recent advances in the development of drugs that target the TGFβ signaling pathway in a tumor-specific or cell type-specific manner to improve the therapeutic window between response rates and adverse effects.
Despite the rising incidence of neonatal abstinence syndrome (NAS), there remains wide practice variation in its management. Many recent studies have focused on implementing new symptom scoring systems, typically as part of larger improvement interventions. Despite the continued use of the Finnegan Scoring System, we performed a quality improvement project to reduce the day of life at discharge and cumulative opioid exposure for newborns with NAS.

We developed a protocol for NAS treatment emphasizing early transfer to general pediatric units, maximization of non-pharmacologic care, and use of as-needed morphine whenever pharmacologic treatment is required. Outcome metrics were the day of life at discharge and cumulative morphine exposure. As a process measure, we also monitored the day of life at transfer to general pediatric units. In addition, we utilized statistical process control charts to track changes in performance.

Twenty-eight patients met the inclusion criteria for analysis over 24 months following project initiation. Day of life at discharge decreased by 61% (20.0 versus 7.89 days,
< 0.001), and cumulative morphine exposure decreased by 81% (13.66 versus 2.57 mg morphine,
≤ 0.001). Day of life at transfer to general pediatric units decreased by 49% (11.13 versus 5.7 days,
= 0.002). There were no readmissions or other identified adverse events.

We achieved significant improvements in NAS outcomes using improved non-pharmacologic care and as-needed morphine. Moreover, the improvement did not require transitioning to a new scoring system. These results support the efficacy and safety of as-needed morphine for NAS management.

Postdischarge phone calls (PDPCs) are recommended to identify and mitigate postdischarge issues such as missed follow-up appointments, medication errors, and failure to activate contingency plans. A current state assessment showed variability in documenting PDPC content and postdischarge issue mitigation. Therefore, the primary aim was to improve the postdischarge issue mitigation documentation rate from 65% to 100% over 16 months.

An interdisciplinary quality improvement team used the Model for Improvement to perform planned sequential interventions over 16 months. The outcome measure was documentation of postdischarge issue mitigation. Process measures included PDPC template use and completion and postdischarge issue identification. Balancing measures included call attempts and caller perceptions of ease of documentation. Interventions included creating a flowsheet note template, creating caller template training sessions, and sharing team data and feedback. We gathered data via reports generated from tdocumentation of postdischarge issue mitigation.This study aimed to validate the Spanish version of the COVID-19 Student Stress Questionnaire (CSSQ), a 7-item tool assessing COVID-19-related stressors among university students, namely, Relationships and Academic Life, Isolation, and Fear of Contagion. Participants were 331 Spanish university students. Factor analyses sustained the three factor solution of the original tool. Data also revealed satisfactory convergent and discriminant validity, suitable internal consistency, and significant associations with psychological symptoms, as measured by the Symptom Checklist-90-Revised. The Spanish version of the CSSQ represents a valid tool to be used in clinical settings to timely identify students at high psychological risk and to develop evidence-based interventions during/after the pandemic.While studies have identified associations between cyber and in-person dating abuse, most research has relied on cross-sectional data, limiting the ability to determine temporality. This study tested the longitudinal associations between cyber and physical and psychological forms of in-person dating abuse. Data were from an ongoing longitudinal study following a group of high school students originally recruited in Southeast Texas, U.S., into their young adulthood. Three waves of data (Waves 4-6) were used, with each wave collected one year apart. At Wave 4, participants' age ranged from 16 years to 20 years (Mean = 18.1 years, Median = 18.0 years, SD = .78). The analytical sample consisted of 879 adolescents/young adults (59% female, 41% male; 32% Hispanics, 28% Black, 29% White, and 11% other) who completed the dating abuse questions. Oxiglutatione Cross-lagged panel analysis showed that dating abuse victimization and perpetration were predictive of subsequent dating abuse of the same type. Cyber dating abuse perpetration was found to predict subsequent physical dating abuse perpetration as well as physical dating abuse victimization, but not vice versa. Further, cyber dating abuse perpetration predicted psychological dating abuse victimization, but not vice versa. Cyber dating abuse victimization was not significantly associated with either physical or psychological dating abuse temporally. Overall, findings suggest that cyber dating abuse perpetration may be a risk marker for both physical and psychological forms of in-person dating abuse. Interventions may benefit from targeting cyber dating abuse perpetration as means to prevent in-person dating abuse.
International guidelines recommend hospital care for patients with severe Coronavirus disease (COVID-19), but fragile health care systems struggle to cope with high number of admissions, placing patients at risk of receiving substandard care. We describe an outpatient ambulatory surveillance and treatment strategy (OPAT) for health care workers (HCWs) with severe COVID-19 during low hospital bed availability periods in Mexico City.

In this observational, descriptive, retrospective study, we included HCWs with severe disease for whom there were no hospital beds available at the time of evaluation. We provided daily assessments by infectious disease specialists, daily ambulatory steroid, oral thromboprophylaxis and domiciliary low-dose oxygen. We recorded the number of patients who recovered, were hospitalized or died on follow-up.

From 18 March 2020 to 16 July 2021, 1739 HCWs attended our service. A total of 540 were diagnosed with COVID-19. Seventy-four had severe COVID-19 and needed hospitalization. Immediate hospitalization was not possible in 56 patients who were sent to the OPAT and included in our study. Twenty-four patients subsequently required hospitalization and 32 recovered as outpatients.

We describe a feasible and safe outpatient management strategy for HCWs with severe COVID-19 in a low-resource setting.

Endoderm-derived organs support indispensable functions in the body. Pluripotent stem cells can generate endoderm-derived cells or tissues and have excellent therapeutic potential to replace the functions of endodermal tissues. However, there is no viable method to induce endodermal precursor cells, definitive endoderm (DE), from canine induced pluripotent stem cells (ciPSCs).

A ciPSC line was used in this study. In order to induce DE, ciPSCs were cultured with high dose activin A and fetal bovine serum. We considered the optimal differentiation period and starting cell density. Next, to reduce the remaining undifferentiated cells and improve the DE induction efficiency, DE was induced from 3D cell aggregates with knockout serum replacement instead of fetal bovine serum. Finally, hepatic and pancreatic induction were performed to investigate whether DE could differentiate into downstream lineages.

After differentiation, some cells expressed the DE markers FOXA2 and SOX17. DE induction period and starting cell density were found to be important for efficient DE induction. However, some cells remained undifferentiated even after optimization of cell density and culture period. Cell differentiation under 3D culture conditions reduced undifferentiated cells and the replacement of fetal bovine serum with knockout serum replacement improved the DE induction efficiency. After hepatic and pancreatic induction, cells expressed some early hepatic and pancreatic markers.

A ciPSC line was successfully differentiated to DE efficiently using a high dose of activin A with knockout serum replacement under 3D cell culture conditions. We believe that this study will be fundamental to achieving the generation of canine endodermal tissues from ciPSCs.
