This paper describes how, as the COVID-19 pandemic emerged, one hospital-based center for nursing research and evidence-based practice capitalized on its unique skill mix to quickly pivot to provide hospital administrators and staff with timely, relevant evidence regarding the care of patients and families, as well as the protection of direct care providers and all support staff. The products produced by this center, both proactive and in direct response, contributed to clinical operations decision-making and thus, tangibly impacted practice. The positive outcomes described speak not only to the clinical environment, but also to the presence and specialized contributions of a multiprofessional center for nursing research and evidence-based practice in such a way that was not possible prior to COVID-19.
Transgender populations experience health inequities that underscore the importance of ensuring access to high quality care. We thematically summarize the health care experiences of transgender youth living in the southeast United States to identify potential barriers and facilitators to health care.

Transgender youth recruited from community settings in an urban area of the southeast United States participated in individual interviews (n=33) and focus groups (n=9) about protective factors. We conducted a thematic analysis of data from 42 participants who described their experiences seeking and receiving health care.

Participants reported a wide range of gender identities. The individual interview sample was majority Black (54.5%) and the mean age was 21.7years and focus group participants were all white and the mean age was 16.8years. Participants described numerous barriers to health care, including limited availability of gender affirming care, logistical challenges, such as gatekeeping and cost, concerns about confidentiality in relation to sexual behavior and gender identity, and inadequate cultural competency among providers regarding gender-affirming care. Facilitators included intake procedures collecting chosen pronouns and names and consistent use of them by providers, and open communication, including active listening.

Findings underscore the need for a multi-component approach to ensure both transgender- and youth-friendly care.

Providers and office staff may benefit from transgender cultural competency trainings. In addition, clinic protocols relating to confidentiality and chosen name and pronoun use may help facilitate access to and receipt of quality care.

Sexual experience has several behavioral consequences in insects, but its physiological basis is less well-understood. The episodic motor activity with a periodicity around 19 s was unintentionally observed in the wildtype Canton-S flies and was greatly reduced in the white-eyed mutant w1118 flies. Episodic motor activity co-exists with several consistent locomotor performances in Canton-S flies whereas reduced episodic motor activity is accompanied by neural or behavioral abnormalities in w1118 flies. The improvements of both episodic motor activity and locomotor performance are co-inducible by a pulsed light illumination in w1118. Here we show that mating experience of w1118 males promoted fast and consistent locomotor activities and increased the power of episodic motor activities. Compared with virgin males, mated ones showed significant increases of boundary preference, travel distance over 60 s, and increased path increments per 0.2 s. In contrast, mated males of Canton-S showed decreased boundary preference, increased travel distance over 60 s, and increased path increments per 0.2 s. Additionally, mated males of w1118 displayed increased power amplitude of periodic motor activities at 0.03-0.1 Hz. These data indicated that mating experience promoted fast and consistent locomotion and improved episodic motor activities in w1118 male flies.Nanoparticles possess unique, size-driven properties. However, they can be challenging to use as they easily agglomerate - their high surface area-to-volume ratio induces strong interparticle forces, generating agglomerates that are difficult to break. This issue prevails in organic particles as well, such as cellulose nanocrystals (CNCs); when in their dried form, strong hydrogen bonding enhances agglomeration. Ultrasonication is widely applied to prepare CNC suspensions, but the methodology employed is non-standardized and typically under-reported, and process efficiency is unknown. This limits the ability to adapt dispersion protocols at industrial scales. Herein, numerical simulations are used in conjunction with validation experiments to define and optimize key parameters for ultrasonic dispersion of CNCs, allowing an operating window to be inferred.
Central nervous system (CNS) metastases are common complications in epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer (NSCLC) treated with EGFR-tyrosine kinase inhibitors (TKIs). However, for patients without baseline CNS metastasis, data regarding the incidence of symptomatic CNS metastasis with EGFR-TKI treatment and its risk factors are still rare.

Patients with EGFR-mutant advanced NSCLC without baseline CNS metastasis who are receiving first- and/or third-generation EGFR-TKIs were included. Overall survival (OS), cumulative incidence of symptomatic CNS metastasis upon treatment failure, and their risk factors were evaluated.

There were 813 patients enrolled, with 562, 106, and 32 received first-line gefitinib, erlotinib, and osimertinib, respectively, while 113 received second-line osimertinib. At a median follow-up of 18.1 months, the median OS was 45.5 months. There were 38 patients developed symptomatic CNS metastases. Osimertinib-treated patients tended to have a lower risk of CNS metastases compared with those treated with first-generation EGFR-TKIs (p = 0.059). However, the cumulative incidence curves of symptomatic CNS metastasis tended to reach a plateau after approximately 3 years regardless of which generation was used, and incidences beyond that period were similar in the two groups. Patients with L858R mutation exhibited a higher risk of developing CNS metastasis than patients with 19del mutation (p = 0.001). Interestingly, the presence of baseline neuroimaging was not associated with the risk of developing CNS metastasis or OS.

Compared with first-generation EGFR-TKIs, osimertinib can delay but not prevent the development of symptomatic CNS metastasis. L858R mutation is an independent risk factor for CNS metastasis.

In recent years immunotherapy has escalated to frontline treatment options for metastatic non-small cell lung cancer. Cardiovascular toxicity from chemotherapeutic agents is well described in this patient population with common underlying risk factors like smoking. We explored cardiovascular toxicity form the addition of immune checkpoint inhibitors to traditional chemotherapy.

This is a retrospective study from SEER-Medicare datasets which represents 34 % of the US population. This study included patients age ≥ 65 years-old with newly diagnosed metastatic non-small cell lung cancer between the years 2013 and 2015. Patients were divided into 2 cohorts, one who received traditional chemotherapy only (control arm) and the others who received immune checkpoint inhibitors in addition to traditional chemotherapy (study arm). The primary endpoint was the hazards of new cardiovascular toxicity in the study versus the control arm.

We identified 6405 patients who met our study criteria. Of these, 5730 patients rwer hazards.
Results from this study are reassuring that adding immune checkpoint inhibitors to chemotherapy is safe and does not result in increased cardiovascular toxicity but instead showed lower hazards.
Health-related quality of life (HRQoL) data complement conventional clinical endpoints when comparing adjuvant gefitinib with chemotherapy in patients with early-stage non-small-cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) mutations. This study aimed to assess changes in HRQoL with adjuvant gefitinib vs chemotherapy in this patient group.

In the phase III ADJUVANT trial, patients with completely resected, stage II-IIIA (N1-N2), EGFR-mutant NSCLC were randomized (11) to receive either gefitinib for 24 months or vinorelbine plus cisplatin (VP) every 3 weeks for four cycles. HRQoL was assessed as a secondary endpoint using the Functional Assessment of Cancer Therapy-Lung Cancer (FACT-L), Lung Cancer Symptom Scale (LCSS) questionnaires, and Trial Outcome Index (TOI) composite score. HRQoL dynamics, improvements, and time to deterioration were compared between groups.

At baseline, 104 of 106, and 80 of 87 patients receiving gefitinib and VP, respectively, completed two questionnaires (FACT-L and LCSS). Baseline scores were balanced between groups. Although HRQoL fluctuated and gradually improved in both groups, longitudinally higher scores were reported with gefitinib than VP (FACT-L, odds ratio 418.16, 95 % confidence interval [CI] 2.75-63509.05, p =  0.019; LCSS, 1.13, 1.04-1.22, p =  0.003; TOI, 88.39, 4.40-1775.05, p =  0.003). Time to deterioration in HRQoL was delayed with gefitinib compared with VP (FACT-L, median 69 vs 6 weeks, hazard ratio 0.62, 95 % CI 0.42-0.90, p =  0.013; LCSS, median 45 vs 6 weeks, 0.63, 0.43-0.93, p =  0.020; TOI, median 164 vs 9 weeks, 0.51, 0.33-0.77, p =  0.001).

Adjuvant gefitinib is associated with improved HRQoL over VP, supporting its use in patients with stage II-IIIA (N1-N2), EGFR-mutant NSCLC.

Severe neurological and endocrine toxicities are well recognised adverse events of immune checkpoint inhibitors. However, the underlying pathophysiology is poorly understood, and classical circulating markers are often non-informative, making it difficult to obtain a precise diagnosis and to initiate timely and effective treatment. Here we investigated immune-modulating activity in the plasma of a mesothelioma patient who developed fatal neuroendocrine toxicity characterised by insulin-dependent diabetes, hypophisitis and a myasthenia-like syndrome while on treatment with the dual PD1 and TIM3 blockade.

We used an invitro functional assay for unbiased detection of plasma dendritic cell-modulating activity, followed by cytokine quantification by the Cytokine Bead Array.

Immunosuppressive treatment as per established guidelines could not prevent the fatal outcome. Patient's plasma contained a dendritic cell-stimulating activity that induced specific markers (CD25+) compatible with T-helper 17 stimulation. Epigenetic pathway inhibitor Consistently, elevated levels of interleukin 17 (IL17A), but no other cytokines, were identified in the patient's plasma but not in controls (healthy volunteers and patients treated with immunotherapy without neuroendocrine toxicities).

If confirmed in larger series, these data suggest IL17 as a candidate diagnostic and therapeutic target in the management of high-grade neuroendocrine immune-related adverse events.
