Objective We evaluated pressure-controlled ventilation (PCV) with multiple programmed levels of positive end expiratory pressure (programmed multi-level ventilation; PMLV) in patients with coronavirus disease 2019 (COVID-19)-related acute respiratory distress syndrome (ARDS). Methods We conducted a multicenter, retrospective study from November 2020 to February 2021. PMLV was used with PCV in all patients with intensive care admission until improvement in oxygenation (fraction of inspired oxygen [FiO2] ≤0.50 and oxygen saturation [SpO2] >92%). The observed outcomes were improvement of hypoxemia, length of mechanical ventilation, partial pressure of carbon dioxide (PaCO2) stability, and adverse events. Results Of 188 mechanically ventilated patients with COVID-19-related ARDS, we analyzed 60 patients treated with PMLV. Hypoxemia improved in 55 (92%) patients, as measured by the change in partial pressure of oxygen/FiO2 and SpO2/FiO2 ratios on day 3 versus day 1, and in 32 (66%) ventilated patients on day 7 versus day 3. The median (interquartile range) length of mechanical ventilation for survivors and non-survivors was 8.4 (4.7–14.9) and 6.7 (3.6–10.3) days, respectively. Conclusions PMLV appears to be a safe and effective ventilation strategy for improving hypoxemia in patients with COVID-19-related ARDS. Further studies are needed comparing the PMLV mode with the conventional ARDS ventilatory approach.

Published: May 2022

Background Youth mental health appears to have been negatively impacted by the COVID-19 pandemic. The impact on substance use is less clear, as is the impact on subgroups of youth, including those with pre-existing mental health or substance use challenges. Objective This hypothesis-generating study examines the longitudinal evolution of youth mental health and substance use from before the COVID-19 pandemic to over one year into the pandemic among youth with pre-existing mental health or substance use challenges. Method A total of 168 youth aged 14–24 participated. Participants provided sociodemographic data, as well as internalizing disorder, externalizing disorder, and substance use data prior to the pandemic’s onset, then every two months between April 2020–2021. Linear mixed models and Generalized Estimating Equations were used to analyze the effect of time on mental health and substance use. Exploratory analyses were conducted to examine interactions with sociodemographic and clinical characteristics. Results There was no change in internalizing or externalizing disorder scores from prior to the pandemic to any point throughout the first year of the pandemic. Substance use scores during the pandemic declined compared to pre-pandemic scores. Exploratory analyses suggest that students appear to have experienced more mental health repercussions than non-students; other sociodemographic and clinical characteristics did not appear to be associated with mental health or substance use trajectories. Conclusions While mental health remained stable and substance use declined from before the COVID-19 pandemic to during the pandemic among youth with pre-existing mental health challenges, some youth experienced greater challenges than others. Longitudinal monitoring among various population subgroups is crucial to identifying higher risk populations. This information is needed to provide empirical evidence to inform future research directions.

Published: May 2022

Objective Evidence of reduction in colorectal cancer (CRC) mortality following CRC screening based on the faecal immunochemical test (FIT) is insufficient. This study aimed to analyse if CRC mortality was reduced after implementing FIT-based screening. Setting The Danish national CRC screening programme. Methods This nationwide cohort study included residents aged 50–71 years invited to the prevalence round of the screening programme. Invitation order was decided by randomising on birth month; the first two birth months to be invited were classified as invited and the five last were classified as not-yet-invited and given a pseudo invitation data. Follow-up was from (pseudo)invitation date until 31 December 2017, emigration or death. Relative risk (RR) of CRC death was calculated with 95% confidence intervals (CIs). Results A total of 897,812 residents were included (29% invited and 71% not-yet-invited). The median follow-up was 3.3 years. The RR of CRC death at end of follow-up was 0.83 (95% CI 0.66; 1.03) among those invited to screening compared with those not yet invited. For men aged 60–71 years, this RR was 0.68 (95% CI 0.49; 0.94). For those participating in screening compared with a similar group of not-yet-invited residents, the RR was 0.71 (95% CI 0.46–1.08). For male participants aged 60–71 years, this RR was 0.49 (95% CI 0.27−0.89). For women and men aged 50–59 years, RRs were small and statistically non-significant. Conclusion This nationwide study showed that even within a median follow-up of only 3.3 years, implementing FIT-based CRC screening reduced CRC mortality among older men.
Continuous Challenges: Case Study of a Sustainable University Adult Education Graduate Program
Authors: Collins Royce Ann , Zacharakis Jeff 
Published: May 2022

Through their history, adult education graduate programs have flourished and dwindled and sustainability always seems to be in jeopardy. This case study examines one program’s growth, decline, and continuous rebirth in the competitive higher education market and academic stratification. Throughout its 55 years of existence, faculty have risen from the ranks to embrace an entrepreneurial spirit and leadership. Through flexibility and diversification, the program has evolved to meet the needs of the current learners. This model is sustainable if all faculty focus on the program first and their own professional reputations second.

Introduction The use of oral anti-cancer therapies is becoming increasingly common in the management of cancers, raising the question of adherence. The objective of this study was to assess adherence to oral anti-cancer therapies, as well as the impact of various factors that may influence it. Methods Patients starting oral chemotherapy (tyrosine kinase inhibitor or cytotoxic) were followed up for 3 months using a medication diary, which was given to the patient by the pharmacist during a multidisciplinary consultation. Adherence was assessed using the diary, as well as by counting the tablets they brought back. Results One hundred and fifty patients were included in the study. The main oral chemotherapy agents prescribed were palbociclib (23.3%), everolimus (18.7%), and capecitabine (13.3%). The adherence at the end of the 3 months, by means of dose intensity (i.e. percent of the dose prescribed that has been taken), was 95.5%. No significant difference in adherence was found based on age, sex, family circumstances, health status, co-medication, type of oral therapy, tumor location, number of previous treatment lines, or presence of toxicity. The main reasons for non-adherence were forgetting (50%) and toxicity (21%). Fifty-seven patients prematurely discontinued the study: 40.3% for toxicity and 36.8% for disease progression. Conclusion Adherence in this study is high in comparison to literature, which can be explained by close multidisciplinary follow-up. Moreover, no significant difference was observed between younger and older patients.

Published: May 2022

Objective Chronic lymphocytic leukemia and small lymphocytic lymphoma remain the most prevalent adult leukemia in Western countries. Novel therapeutics have established long-term efficacy and have changed the landscape in patient management. In contrast, novel approaches pose opportunities for patients to be treated for finite durations. In this manuscript, we highlight long-term safety and efficacy data with Bruton's tyrosine kinase inhibitors and combination BCL2 + anti-CD20 therapies. We also offer key considerations for treatment selection and outline ongoing trials which may continue to expand therapeutic options and approaches. Data sources An electronic search of the PubMed database was performed to obtain key literature in chronic lymphocytic leukemia and small lymphocytic lymphoma published using the following search terms: chronic lymphocytic leukemia/small lymphocytic lymphoma, Richter syndrome, and histologic transformation. The search results were narrowed by selecting studies in humans published in English. Results were confined to the following article types: Clinical Trial, Phase II; Clinical Trial, Phase III; Clinical Trial, Phase IV; Guideline; Randomized Controlled Trial; Meta-Analysis; Systematic Reviews; and Validation Studies. Data summary Chronic lymphocytic leukemia and small lymphocytic lymphoma are different manifestations of the same disease and are managed in much the same way. Bruton's tyrosine kinase inhibitors have demonstrated long and durable efficacy benefits in patients with newly diagnosed chronic lymphocytic leukemia/small lymphocytic lymphoma and in the relapsed/refractory setting. Despite these benefits, long terms adverse events have posed challenges for patients and have led to treatment discontinuations. Additionally, the use of monotherapy Bruton's tyrosine kinase inhibitor's requires chronic use of the medications leading to added financial implications. BCL2 inhibition with venetoclax in combination with anti-CD20 monoclonal antibodies has offered a novel and finite treatment approach in frontline and relapsed chronic lymphocytic leukemia/small lymphocytic lymphoma. Ongoing clinical trials are in investigating this modality further to enhance durable responses utilizing a combination Bruton's tyrosine kinase inhibitor's and BCL2 inhibitors. Conclusion The treatment armamentarium of chronic lymphocytic leukemia/small lymphocytic lymphoma continues to evolve. Despite the long term, durable responses with Bruton's tyrosine kinase inhibitor's, it is likely that finite treatment durations could become the standard of care as a result of continued, long-term responses.

Published: May 2022

Introduction Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) are common toxicities associated with chimeric antigen receptor (CAR) T-cell therapy. Severe grade 3 or higher ICANS is less common and requires the use of corticosteroids with or without an Interleukin (IL)-6 receptor antagonist. Although corticosteroids are effective in the management of CRS and ICANS, their impact on CAR T efficacy remains unknown. Case report We present the case of a 65-year-old male who received CAR T-cell therapy with brexucabtagene autoleucel for stage I/II Mantle Cell Lymphoma (MCL) and achieved complete remission despite receiving a prolonged course of corticosteroids for severe ICANS. Management and outcome The patient received treatment with high-dose corticosteroids, tocilizumab, and anakinra, in addition to multiple antiepileptic agents. Despite a remitting relapsing pattern of ICANS, the patient not only recovered from the life-threatening complication but also achieved a complete remission at three months post CAR T. Conclusion This case describes the successful use of corticosteroids for the management of ICANS in a patient treated with CAR T-cell therapy for MCL.
The ‘tears’ score: A tool for grading and monitoring epiphora
Authors: Schulz Christopher B. , Malhotra Raman 
Published: May 2022

Purpose To test the reliability, validity and utility of the TEARS score, a scale of clinical and patient-reported severity in patients with epiphora, comprising 4 subscales: Times wiping (T), clinical Effects (E), Activity limitation (A), and symptoms of Reflex epiphora (R). Methods The TEARS score was completed by 136 patients with epiphora (78 treated surgically, and 51 non-surgically). Inter-rater reliability was evaluated using Cohen's Kappa and Bland-Altman analysis. 129 (95%) participants were followed up 2–6 months after baseline (non-surgical patients) or 3–6 months post-operatively (surgical patients). For each TEARS subscale, differences in scores were compared. Convergent validity was evaluated by testing correlation between TEARS and both The Lacrimal Symptom Questionnaire (Lac-Q) and The Watery Eye Quality of Life Score (WEQOL). Results Inter-rater reliability (Cohen's K) ranged from 0.5 for ‘A’ and ‘R’ to 0.8 for ‘T’ and ‘E’ subscales. Scores were lower post-operatively in surgical patients (p < 0.001). ‘R’ scores (reflex tearing) were higher in non-surgical cases compared with surgical (p = 0.02) but no difference was observed in other subscales at baseline. TEARS subscale scores were positively correlated with both WEQOL (r = 0.51 to 0.73) and Lac-Q score (r = 0.55 to 0.63). Conclusion The TEARS score is quickly and easily implemented in a busy clinical setting. It provides an overview of both subjective and objective clinical severity in patients with epiphora, with appropriate reliability, post-operative responsiveness and convergent validity for this purpose and in this setting. It is a valuable template to be used alongside individualised symptomology.

Authors: Chua Chai-Hock , Lu Ming-Jen , Chao Hung-Hsing 
Published: May 2022

Purpose: To report the patency rates after implantation of an interwoven nitinol stent to salvage failing arteriovenous grafts (AVGs) caused by intragraft stenoses. Methods: Between May 2018 and May 2020, 21 Supera stents were placed in 20 patients (18 women; mean age: 79.9 years) who had a failing AVG due to repeat intragraft stenoses. Recurrent AVG dysfunction with same intragraft stenosis within 3 months after first time angioplasty was a criterion for stenting. Those with concurrent treatment for other lesions were excluded. Results: The technical success rate was 100%. Intragraft stenoses were treated at a median of 19.7 (interquartile range: 6–36) months after graft creation. Access circuit primary patency rates after stent placement were 84% and 35% at 6 and 12 months, respectively. Access circuit secondary patency rates were 100% at 6 and 12 months and 89% at 18 months. Only one patient presented with graft failure due to proximal drainage vein occlusion. The target lesion patency rates were 100% at 6 months and 75% at 12 months. The rate of reintervention for intragraft lesion was 0.15 procedures per year. Stent distortion did not occur under regular cannulation. Conclusion: The interwoven nitinol stent is a promising treatment for failing AVGs with recurrent intragraft stenoses. The 1-year access circuit primary, secondary, and target lesion patency rates were acceptable, with a low reintervention rate. Stent fracture does not occur in areas of needle puncture.

Published: May 2022

Background: Peripheral intravenous catheter (PIVC) placement is the most common invasive clinical procedure, often performed by nurses in hospitals worldwide. This study aimed to assess the effect of clinical guideline education on the knowledge and practice of nurses for PIVC placement based on short message service (SMS). Methods: In a quasi-experimental study with parallel groups, 66 nurses working in two general university hospitals in Iran were enrolled. Data was collected from 2017 to 2018. PIVC placement was assessed before, immediately, and 4 weeks after educational intervention based on SMS (twice a day for 10 days). Results: Nurses’ knowledge score immediately after intervention versus before intervention was higher in the intervention group than in the control group (4.48 vs −0.70; p < 0.001). Nurses’ knowledge score in 4 weeks after intervention versus immediately after intervention was lower in the intervention group than in the control group (0.03 vs 0.42; p = 0.014). Nurses’ knowledge scores 4 weeks after intervention versus before intervention was higher in the intervention group than in the control group (4.52 vs −0.27; p < 0.001). Nurses’ practice score immediately after intervention versus before intervention was higher in the intervention group than in the control group (0.57 vs −0.18; p = 0.174). Nurses’ practice score 4 weeks after intervention vs immediately after intervention was higher in the intervention group than in the control group (−0.10 vs −0.38; p = 0.046). Nurses’ practice scores 4 weeks after intervention versus before intervention was higher in the intervention group than in the control group (0.47 vs −0.56; p = 0.001). Conclusion: Educational intervention by SMS had a significant effect on increasing the knowledge and practice of nurses toward clinical guidelines for PIVC placement. Therefore, it is suggested that educational intervention by SMS be conducted to improve nurses’ knowledge as an effective educational method.

Studies into drug combination at low doses are a promising approach to the management of pain and inflammation. The aim of this study was to evaluate the anti-edema and anti-hyperalgesic effects of a combination of diclofenac and andrographolide. Male Sprague-Dawley rats were first treated with diclofenac or andrographolide alone (3–100 mg/kg), as well as a combination of the 2 drugs. Carrageenan was then injected into the right hind paw of rats, and changes in paw volume and sensitivity to mechanical (von Frey) and thermal (Hargreaves test) stimuli measured. Results showed drug combination produced synergistic effects at reducing paw edema especially at lower doses, with a Loewe synergy score of 13.02 ± 8.75 in SynergyFinder and a combination index of .41 ± .18 after isobolographic analysis. Again synergy scores for decreasing response to 1.0 and 3.6 g force application of von Frey filaments after drug combination were 10.127 ± 5.68 and 8.554 ± 6.53, respectively, in SynergyFinder. Synergistic effects were also seen after drug combination in the Hargreaves test with a synergy score of 5.136 ± 16.38. In conclusion, combination of diclofenac with andrographolide showed better pharmacologic effects after carrageenan injection and was more synergistic at low-dose combinations.
Resolute onyx stent more effective than wingspan stent at preventing procedural complications and long-term restenosis
Authors: Hassan Ameer E. , Khalil Mohammad , Desai Sohum , Tekle Wondwossen G. 
Published: May 2022

Background and Purpose Angioplasty and stenting is a treatment option for patients with medically refractory symptomatic intracranial atherosclerotic disease (sICAD). Currently the Wingspan Stent System (WSS) is the only FDA approved device for this indication. We find the Resolute (R) Onyx Stent, a drug-eluting balloon mounted stent (DES), a better alternative to the WSS for treatment of sICAD. Herein, we present our findings comparing the two stents based on our single center experience. Methods A prospectively maintained neuro-endovascular databased was queried for patients between January 2013 to June 2021. Inclusion criteria for patients included sICAD with failed medical management, and intracranial stenting with either R-Onyx DES or WSS, including patients treated within 7 days of their last stroke. Primary outcomes were assessed via the occurrence of ischemic or hemorrhagic stroke or death within 72 h of the procedure. Secondary outcomes consisted of recurrent stroke or significant in-stent restenosis evaluated by a clinical or angiographic follow-up at 6 months. Results A total of 184 patients, average age 61.26 (SD = 12.53) (44% women), were eligible for analysis with 58 having R-onyx DES and 126 having WSS. Within 72 h, the primary outcome was observed in 1.7% (n = 1) of patients in the R-onyx DES group and 6.3% (n = 8) of patients in the WSS group (p = 0.089). Among 41 angiographic and clinical follow-ups in the R-onyx DES group, none had a recurrent stroke, while among 101 patients who had follow-up in the WSS group, 8.9% (n = 9) had a stroke (p = 0.024). At a 6-month angiographic follow-up, there was a significantly lower rate of symptomatic in-stent restenosis among the R-onyx DES group with 1.7% (n = 1) compared with 21.4% (n = 27) in the WSS group (p = 0.0003). Conclusion R-onyx DES is more effective than WSS in treating sICAD with low rates of periprocedural complications and long-term strokes and symptomatic in-stent restenosis. Future prospective randomized multicenter trials are needed.

Published: May 2022

Objective This study aims to identify the types and prevalence of absence of the celiac trunk by using multidetector computed tomography (MDCT) angiography, and analyze their probable embryological mechanisms. Methods A retrospective study was carried out on 2500 abdominal MDCT angiography images. The absence of the celiac trunk was defined as that the celiac trunk is not exist, more specifically, there is not such an arterial trunk containing at least two major branches of the celiac trunk. Various types of the absence of the celiac trunk were investigated. Results Of the 2500 patients, 19 (0.76%) patients were identified as an absence of the celiac trunk. According to its definition and classification, the absence of the celiac trunk could be divided into five types: type I (LGA + CHA + SA + SMA), type II (HM trunk + LGA + SA), type III (SM trunk + LGA + CHA), type IV (GM trunk + CHA + SA), and type V (other type); and these types were observed in 5 patients (0.20%), 9 patients (0.36%), 3 patients (0.12%), 0 patients (0.00%), and 2 (0.08%) patients, respectively. There were more examples of the types I and II than of the types III–V ( p = 0.004). Conclusion We systematically classified the absence of the celiac trunk based on its MDCT angiography findings. Abnormal interruptions and persistence of the longitudinal anastomosis, regression of vascular root, and emergence of replaced artery could all be the embryological mechanisms of various types of the absence of the celiac trunk.
