Intrapartum Cesarean Section and Perinatal Outcomes after Epidural Analgesia or Remifentanil-PCA in Breech and Twin Deliveries.

Comparative data on the potential impact of various forms of labor analgesia on the mode of delivery and neonatal complications in vaginal deliveries of singleton breech and twin fetuses are lacking. The present study aimed to determine the associations between type of labor analgesia (epidural analgesia (EA) vs. remifentanil patient-controlled analgesia (PCA)) and intrapartum cesarean sections (CS), and maternal and neonatal adverse outcomes in breech and twin vaginal births. A retrospective analysis of planned vaginal breech and twin deliveries at the Department of Perinatology, University Medical Centre Ljubljana, was performed for the period 2013-2021, using data obtained from the Slovenian National Perinatal Information System. The pre-specified outcomes studied were the rates of CS in labor, postpartum hemorrhage, obstetric anal sphincter injury (OASI), an Apgar score of <7 at 5 min after birth, birth asphyxia, and neonatal intensive care admission. A total of 371 deliveries were analyzed, including 127 term breech and 244 twin births. There were no statistically significant nor clinically relevant differences between the EA and remifentanil-PCA groups in any of the outcomes studied. Our findings suggest that both EA and remifentanil-PCA are safe and comparable in terms of labor outcomes in singleton breech and twin deliveries.

Multivitamin Supplementation Improves Memory in Older Adults: A Randomized Clinical Trial

BackgroundMaintenance of cognitive abilities is of critical importance to older adults, yet few effective strategies to slow cognitive decline currently exist. Multivitamin supplementation is used to promote general health; it is unclear whether it favorably affects cognition in older age. ObjectivesTo examine the effect of daily multivitamin/multimineral supplementation on memory in older adults. MethodsThe COcoa Supplement and Multivitamin Outcomes Study Web (COSMOS-Web) ancillary study (NCT04582617) included 3562 older adults. Participants were randomly assigned to a daily multivitamin supplement (Centrum Silver) or placebo and evaluated annually with an Internet-based battery of neuropsychological tests for 3 y. The prespecified primary outcome measure was change in episodic memory, operationally defined as immediate recall performance on the ModRey test, after 1 y of intervention. Secondary outcome measures included changes in episodic memory over 3 y of follow-up and changes in performance on neuropsychological tasks of novel object recognition and executive function over 3 y. ResultsCompared with placebo, participants randomly assigned to multivitamin supplementation had significantly better ModRey immediate recall at 1 y, the primary endpoint (t(5889) = 2.25, P = 0.025), as well as across the 3 y of follow-up on average (t(5889) = 2.54, P = 0.011). Multivitamin supplementation had no significant effects on secondary outcomes. Based on cross-sectional analysis of the association between age and performance on the ModRey, we estimated that the effect of the multivitamin intervention improved memory performance above placebo by the equivalent of 3.1 y of age-related memory change. ConclusionsDaily multivitamin supplementation, compared with placebo, improves memory in older adults. Multivitamin supplementation holds promise as a safe and accessible approach to maintaining cognitive health in older age. This trial was registered at clinicaltrials.gov as NCT04582617.

Heart failure, peripheral artery disease, and dapagliflozin: a patient-level meta-analysis of DAPA-HF and DELIVER.

Because an increased risk of amputation with canagliflozin was reported in the CANVAS trials, there has been a concern about the safety of sodium-glucose cotransporter 2 inhibitors in patients with peripheral artery disease (PAD) who are at higher risk of amputation. A patient-level pooled analysis of the DAPA-HF and DELIVER trials, which evaluated the efficacy and safety of dapagliflozin in patients with heart failure (HF) with reduced, mildly reduced/preserved ejection fraction, respectively, was conducted. In both trials, the primary outcome was the composite of worsening HF or cardiovascular death, and amputation was a prespecified safety outcome. Peripheral artery disease history was available for 11 005 of the total 11 007 patients. Peripheral artery disease was reported in 809 of the 11 005 patients (7.4%). Median follow-up was 22 months (interquartile range 17-30). The rate of the primary outcome (per 100 person-years) was higher in PAD patients than that in non-PAD patients: 15.1 [95% confidence interval (CI) 13.1-17.3) vs. 10.6 (10.2-11.1]; adjusted hazard ratio 1.23 (95% CI 1.06-1.43). The benefit of dapagliflozin on the primary outcome was consistent in patients with [hazard ratio 0.71 (95% CI 0.54-0.94)] and without PAD [0.80 (95% CI 0.73-0.88)] (Pinteraction = 0.39). Amputations, while more frequent in PAD patients, were not more common with dapagliflozin, compared with placebo, irrespective of PAD status (PAD, placebo 4.2% vs. dapagliflozin 3.7%; no PAD, placebo 0.4% vs. dapagliflozin 0.4%) (Pinteraction = 1.00). Infection rather than ischaemia was the main trigger for amputation, even in patients with PAD. The risk of worsening HF or cardiovascular death was higher in patients with PAD, as was the risk of amputation. The benefits of dapagliflozin were consistent in patients with and without PAD, and dapagliflozin did not increase the risk of amputation.

Cardiac and kidney benefits of empagliflozin in heart failure across the spectrum of kidney function: insights from the EMPEROR-Preserved trial.

In the EMPEROR-Preserved trial, empagliflozin improved clinical outcomes of patients with heart failure (HF) with preserved ejection fraction. In this pre-specified analysis, we aim to study the effect of empagliflozin on cardiovascular and kidney outcomes across the spectrum of kidney function. Patients were categorized by the presence or absence of chronic kidney disease (CKD) at baseline (CKD defined by an estimated glomerular filtration rate [eGFR] <60 ml/min/1.73 m2 or urine albumin to creatinine ratio >300 mg/g). The primary and key secondary outcomes were (i) a composite of cardiovascular death or first HF hospitalization (primary outcome); (ii) total number of HF hospitalization, (iii) eGFR slope; and a pre-specified exploratory composite kidney outcome including a sustained ≥40% decline in eGFR, chronic dialysis or renal transplant. The median follow-up was 26.2 months. A total of 5988 patients were randomized to empagliflozin or placebo, of whom 3198 (53.5%) had CKD. Irrespective of CKD status, empagliflozin reduced the primary outcome (with CKD: hazard ratio [HR] 0.80, 95% confidence interval [CI] 0.69-0.94; without CKD: HR 0.75, 95% CI 0.60-0.95; interaction p = 0.67) and total (first and recurrent) hospitalizations for HF (with CKD: HR 0.68, 95% CI 0.54-0.86; without CKD: HR 0.89, 95% CI 0.66-1.21; interaction p = 0.17). Empagliflozin slowed the slope of eGFR decline by 1.43 (1.01-1.85) ml/min/1.73 m2 /year in patients with CKD and 1.31 (0.88-1.74) ml/min/1.73 m2 /year in patients without CKD (interaction p = 0.70). Empagliflozin did not reduce the pre-specified kidney outcome in patients with or without CKD (with CKD: HR 0.97, 95% CI 0.71-1.34; without CKD: HR 0.92, 95% CI 0.58-1.48; interaction p = 0.86) but slowed progression to macroalbuminuria and reduced the risk of acute kidney injury. The effect of empagliflozin on the primary composite outcome and the key secondary outcomes was consistent across five baseline eGFR categories (all interaction p >0.05). Empagliflozin was well tolerated independent of CKD status. In EMPEROR-Preserved, empagliflozin had a beneficial effect on the key efficacy outcomes in patients with and without CKD. Overall, the benefit and safety of empagliflozin was consistent across a wide range of kidney function spectrum, down to a baseline eGFR of 20 ml/min/1.73 m2 .

Tau-targeting antisense oligonucleotide MAPTRx in mild Alzheimer’s disease: a phase 1b, randomized, placebo-controlled trial

Tau plays a key role in Alzheimer’s disease (AD) pathophysiology, and accumulating evidence suggests that lowering tau may reduce this pathology. We sought to inhibit MAPT expression with a tau-targeting antisense oligonucleotide (MAPTRx) and reduce tau levels in patients with mild AD. A randomized, double-blind, placebo-controlled, multiple-ascending dose phase 1b trial evaluated the safety, pharmacokinetics and target engagement of MAPTRx. Four ascending dose cohorts were enrolled sequentially and randomized 3:1 to intrathecal bolus administrations of MAPTRx or placebo every 4 or 12 weeks during the 13-week treatment period, followed by a 23 week post-treatment period. The primary endpoint was safety. The secondary endpoint was MAPTRx pharmacokinetics in cerebrospinal fluid (CSF). The prespecified key exploratory outcome was CSF total-tau protein concentration. Forty-six patients enrolled in the trial, of whom 34 were randomized to MAPTRx and 12 to placebo. Adverse events were reported in 94% of MAPTRx-treated patients and 75% of placebo-treated patients; all were mild or moderate. No serious adverse events were reported in MAPTRx-treated patients. Dose-dependent reduction in the CSF total-tau concentration was observed with greater than 50% mean reduction from baseline at 24 weeks post-last dose in the 60 mg (four doses) and 115 mg (two doses) MAPTRx groups. Clinicaltrials.gov registration number: NCT03186989.

Interventions to Reduce Severe Brain Injury Risk in Preterm Neonates

Interventions to reduce severe brain injury risk are the prime focus in neonatal clinical trials. To evaluate multiple perinatal interventions across clinical settings for reducing the risk of severe intraventricular hemorrhage (sIVH) and cystic periventricular leukomalacia (cPVL) in preterm neonates. MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases were searched from inception until September 8, 2022, using prespecified search terms and no language restrictions. Randomized clinical trials (RCTs) that evaluated perinatal interventions, chosen a priori, and reported 1 or more outcomes (sIVH, cPVL, and severe brain injury) were included. Two co-authors independently extracted the data, assessed the quality of the trials, and evaluated the certainty of the evidence using the Cochrane GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. Fixed-effects pairwise meta-analysis was used for data synthesis. The 3 prespecified outcomes were sIVH, cPVL, and severe brain injury. A total of 221 RCTs that assessed 44 perinatal interventions (6 antenatal, 6 delivery room, and 32 neonatal) were included. Meta-analysis showed with moderate certainty that antenatal corticosteroids were associated with small reduction in sIVH risk (risk ratio [RR], 0.54 [95% CI, 0.35-0.82]; absolute risk difference [ARD], -1% [95% CI, -2% to 0%]; number needed to treat [NNT], 80 [95% CI, 48-232]), whereas indomethacin prophylaxis was associated with moderate reduction in sIVH risk (RR, 0.64 [95% CI, 0.52-0.79]; ARD, -5% [95% CI, -8% to -3%]; NNT, 20 [95% CI, 13-39]). Similarly, the meta-analysis showed with low certainty that volume-targeted ventilation was associated with large reduction in risk of sIVH (RR, 0.51 [95% CI, 0.36-0.72]; ARD, -9% [95% CI, -13% to -5%]; NNT, 11 [95% CI, 7-23]). Additionally, early erythropoiesis-stimulating agents (RR, 0.68 [95% CI, 0.57-0.83]; ARD, -3% [95% CI, -4% to -1%]; NNT, 34 [95% CI, 22-67]) and prophylactic ethamsylate (RR, 0.68 [95% CI, 0.48-0.97]; ARD, -4% [95% CI, -7% to 0%]; NNT, 26 [95% CI, 13-372]) were associated with moderate reduction in sIVH risk (low certainty). The meta-analysis also showed with low certainty that compared with delayed cord clamping, umbilical cord milking was associated with a moderate increase in sIVH risk (RR, 1.82 [95% CI, 1.03-3.21]; ARD, 3% [95% CI, 0%-6%]; NNT, -30 [95% CI, -368 to -16]). Results of this study suggest that a few interventions, including antenatal corticosteroids and indomethacin prophylaxis, were associated with reduction in sIVH risk (moderate certainty), and volume-targeted ventilation, early erythropoiesis-stimulating agents, and prophylactic ethamsylate were associated with reduction in sIVH risk (low certainty) in preterm neonates. However, clinicians should carefully consider all of the critical factors that may affect applicability in these interventions, including certainty of the evidence, before applying them to clinical practice.

Safety of measles, mumps, and rubella vaccine in adolescents and adults in the vaccine safety Datalink

Measles, mumps, and rubella vaccine (MMR) is routinely administered to children; however, adolescents and adults may receive MMR for various reasons. Safety studies in adolescents and adults are limited. We report on safety of MMR in this age group in the Vaccine Safety Datalink. We included adolescents (aged 9-17years) and adults (aged≥18years) who received≥1 dose of MMR from January 1, 2010-December 31, 2018. Pre-specified outcomes were identified by diagnosis codes. Clinically serious outcomes included anaphylaxis, encephalitis/myelitis, Guillain-Barré syndrome, immune thrombocytopenia, meningitis, and seizure. Non-serious outcomes were allergic reaction, arthropathy, fever, injection site reaction, lymphadenopathy, non-specific reaction, parotitis, rash, and syncope. All serious outcomes underwent medical record review. Outcome-specific incidence was calculated in pre-defined post-vaccination windows. A self-controlled risk interval design was used to determine the relative risk of each outcome in a risk window after vaccination compared to a more distal control window. During the study period, 276,327 MMR doses were administered to adolescents and adults. Mean age of vaccinees was 34.8years; 65.8% were female; 53.2% of doses were administered simultaneously with≥1 other vaccine. Serious outcomes were rare, with incidence≤6 per 100,000 doses for each outcome assessed, and none had a significant elevation in incidence during the risk window compared to the control window. Incidence of non-serious outcomes per 100,000 doses ranged from 3.4 for parotitis to 263.0 for arthropathy. Other common outcomes included injection site reaction and rash (157.0 and 112.9 per 100,000 doses, respectively). Significantly more outcomes were observed during the risk window compared to the control window for all non-serious outcomes except parotitis. Some variability was observed by sex and age group. Serious outcomes after MMR are rare in adolescents and adults, but vaccinees should be counseled regarding anticipated local and systemic non-serious adverse events.

Hemodynamic Changes with Umbilical Cord Milking in Nonvigorous Newborns: A Randomized Cluster Cross-over Trial

To assess the hemodynamic safety and efficacy of umbilical cord milking (UCM) compared with early cord clamping (ECC) in nonvigorous newborn infants enrolled in a large multicenter randomized cluster-crossover trial. Two hundred twenty-seven nonvigorous term or near-term infants who were enrolled in the parent UCM vs ECC trial consented for this substudy. An echocardiogram was performed at 12±6hours of age by ultrasound technicians blinded to randomization. The primary outcome was left ventricular output (LVO). Prespecified secondary outcomes included measured superior vena cava (SVC) flow, right ventricular output (RVO), peak systolic strain, and peak systolic velocity by tissue Doppler examination of the RV lateral wall and the interventricular septum. Nonvigorous infants receiving UCM had increased hemodynamic echocardiographic parameters as measured by higher LVO (225±64 vs 187±52mL/kg/min; P<.001), RVO (284±88 vs 222±96mL/kg/min; P<.001), and SVC flow (100±36 vs 86±40mL/kg/min; P<.001) compared with the ECC group. Peak systolic strain was lower (-17±3 vs -22±3%; P<.001), but there was no difference in peak tissue Doppler flow (0.06 m/s [IQR, 0.05-0.07 m/s] vs 0.06 m/s [IQR, 0.05-0.08 m/s]). UCM increased cardiac output (as measured by LVO) compared with ECC in nonvigorous newborns. Overall increases in measures of cerebral and pulmonary blood flow (as measured by SVC and RVO flow, respectively) may explain improved outcomes associated with UCM (less cardiorespiratory support at birth and fewer cases of moderate-to-severe hypoxic ischemic encephalopathy) among nonvigorous newborn infants.

Long-term gastrointestinal outcomes of COVID-19

A comprehensive evaluation of the risks and 1-year burdens of gastrointestinal disorders in the post-acute phase of COVID-19 is needed but is not yet available. Here we use the US Department of Veterans Affairs national health care databases to build a cohort of 154,068 people with COVID-19, 5,638,795 contemporary controls, and 5,859,621 historical controls to estimate the risks and 1-year burdens of a set of pre-specified incident gastrointestinal outcomes. We show that beyond the first 30 days of infection, people with COVID-19 exhibited increased risks and 1-year burdens of incident gastrointestinal disorders spanning several disease categories including motility disorders, acid related disorders (dyspepsia, gastroesophageal reflux disease, peptic ulcer disease), functional intestinal disorders, acute pancreatitis, hepatic and biliary disease. The risks were evident in people who were not hospitalized during the acute phase of COVID-19 and increased in a graded fashion across the severity spectrum of the acute phase of COVID-19 (non-hospitalized, hospitalized, and admitted to intensive care). The risks were consistent in comparisons including the COVID-19 vs the contemporary control group and COVID-19 vs the historical control group as the referent category. Altogether, our results show that people with SARS-CoV-2 infection are at increased risk of gastrointestinal disorders in the post-acute phase of COVID-19. Post-covid care should involve attention to gastrointestinal health and disease.

Kidney and Cardiovascular Effects of Canagliflozin According to Age and Sex: A Post Hoc Analysis of the CREDENCE Randomized Clinical Trial

It is unclear whether the effect of canagliflozin on adverse kidney and cardiovascular events in those with diabetic kidney disease varies by age and sex. We assessed the effects of canagliflozin among age group categories and between sexes in the CREDENCE study. Secondary analysis of a randomized controlled trial. Participants in the CREDENCE trial. Participants were randomly assigned to canagliflozin 100 mg daily or placebo. Primary composite outcome of kidney failure, doubling of serum creatinine, or death due to kidney or cardiovascular disease. Pre-specified secondary and safety outcomes were also analyzed. Outcomes were evaluated by age at baseline (<60, 60-69, and ≥70 years) and sex in the intention-to-treat population using Cox regression models. The mean age of the cohort was 63.0±9.2 years and 34% were female. Older age and female sex were independently associated with a lower risk of the composite of adverse kidney outcomes. There was no evidence that the effect of canagliflozin on the primary outcome (a composite of kidney failure, a doubling of the serum creatinine, or death from kidney or cardiovascular causes) differed between age groups (HR 0.67, 95% CI 0.52 to 0.87; HR 0.63, 95% CI 0.48 to 0.82; and HR 0.89, 95% CI 0.61 to 1.29; for the <60, 60-69, and ≥70 year groups, respectively; Pinteraction=0.3); or among females and males (HR 0.71, 95% CI 0.54 to 0.95; and HR 0.69, 95% CI 0.56 to 0.84, respectively; Pinteraction=0.8). No differences in safety outcomes by age group or sex were observed. This was a post hoc analysis with multiple comparisons. Canagliflozin consistently reduced the relative risk of kidney events in people with diabetic kidney disease in both sexes and across age subgroups. Owing to higher background risk, the absolute reduction in adverse kidney outcomes was greater in younger participants.

Abstract P4-01-10: Evaluating the safety of tucatinib in combination with trastuzumab and capecitabine for human epidermal growth factor 2 (HER2)-positive metastatic breast cancer in a real-world setting

Abstract Background: Tucatinib, a highly selective tyrosine kinase inhibitor (TKI) for human epidermal growth factor 2 (HER2) receptor, received FDA approval in combination with trastuzumab and capecitabine for metastatic HER2-positive breast cancer based on the HER2CLIMB trial. While the efficacy data is promising, the tucatinib-containing triplet regimen is associated with significant toxicity and many drug-drug interactions (DDIs). The toxicity profile of tucatinib in regards to adverse events (AEs) and DDIs has not been reported outside of the HER2CLIMB trial. Additionally, with the development of many new HER2 targeted therapies including antibody-drug conjugates (ADCs) such as trastuzumab deruxtecan, efficacy in regards to therapy sequence is still unknown. Here, we describe the safety and efficacy of tucatinib in a real-world setting. Methods: This single-center, retrospective, cohort study included patients (pts) with a diagnosis of HER2- positive locally advanced or metastatic breast cancer pts that were newly initiated on tucatinib therapy at the Duke Breast Oncology Clinic following FDA approval from April 17, 2020 to June 9, 2021. Pts were evaluated for the pre-specified outcomes for the duration of tucatinib therapy, until progression of disease, or for at least 6 months follow-up. AEs reviewed included palmar-plantar erythrodysesthesia syndrome (PPE), diarrhea, fatigue, rash, anemia, thrombocytopenia, neutropenia, nausea, vomiting, mucositis, hepatotoxicity, and nephrotoxicity, defined according to the Common Terminology Criteria for Adverse Events (CTCAE) grading criteria. Overall response was categorized as complete response, partial response, stable disease, or progressive disease, defined according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, at first staging after therapy initiation. The overall response rate was stratified by prior standard therapies, pts who did not receive capecitabine therapy with tucatinib, and the presence or absence of brain metastases. Results: A total of 23 pts (N=23) were included in the cohort, 52% of which had brain metastases and 9% with leptomeningeal disease. Pts had a median of 3 prior lines of therapy in the metastatic setting including: lapatinib (9%), neratinib (30%), trastuzumab deruxtecan (13%), trastuzumab emtansine (74%). All pts experienced AEs, most of which were mild or moderate severity. The most common AEs reported were fatigue (70%), PPE (61%), nausea (61%), and anemia (61%). Severe AEs occurred in 6 pts (26%) with grade 3 or 4 hepatotoxicity in 13%. Only 2 pts discontinued therapy due to AEs (grade 4 hepatoxicity, grade 2 fatigue). Due to capecitabine intolerance, 13% received tucatinib and trastuzumab doublet therapy. There were 9 pts (39%) that experienced a DDI with tucatinib requiring therapy modification or close monitoring. At first staging, partial response was seen in 26% while 35% demonstrated stable disease and 30% progressive disease. Pts with previous neratinib therapy demonstrated a partial response of 14% and a stable disease response of 29%. No pts with previous trastuzumab deruxtecan or omission of capecitabine therapy experienced a partial or stable disease response. Conclusions: The rate of AEs were similar in a real-world setting compared to the HER2CLIMB trial with a lower rate of severe adverse events, however, a higher rate of hepatotoxicity. Given the high rate of drug interactions identified with tucatinib, concurrent medications should be reviewed for appropriate therapy adjustments and monitoring. Additional data is needed in regards to sequencing and impact on therapy efficacy. Citation Format: Heather Moore, Carey Anders, Sarah L. Sammons, Alaattin Erkanli, Alice Parish, Christina DiCola.

Association of marital/partner status and patient-reported outcomes following myocardial infarction: a systematic review and meta-analysis.

Little is known about the relationship between marital/partner status and patient-reported outcome measures (PROMs) following myocardial infarction (MI). We conducted a systematic review/meta-analysis and explored potential sex differences. We searched five databases (Medline, Web of Science, Scopus, EMBASE, and PsycINFO) from inception to 27 July 2022. Peer-reviewed studies of MI patients that evaluated marital/partner status as an independent variable and reported its associations with defined PROMs were eligible for inclusion. Results for eligible studies were classified into four pre-specified outcome domains [health-related quality of life (HRQoL), functional status, symptoms, and personal recovery (i.e. self-efficacy, adherence, and purpose/hope)]. Study quality was appraised using Newcastle-Ottawa Scale, and data were synthesized by outcome domains. We conducted subgroup analysis by sex. We included 34 studies (n = 16 712), of which 11 were included in meta-analyses. Being married/partnered was significantly associated with higher HRQoL {six studies [n = 2734]; pooled standardized mean difference, 0.37 [95% confidence interval (CI), 0.12-0.63], I 2 = 51%} but not depression [three studies (n = 2005); pooled odds ratio, 0.72 (95% CI, 0.32-1.64); I 2 = 65%] or self-efficacy [two studies (n = 356); pooled β, 0.03 (95% CI, -0.09 to 0.14); I 2 = 0%]. The associations of marital/partner status with functional status, personal recovery outcomes, and symptoms of anxiety and fatigue were mixed. Sex differences were not evident due to mixed results from the available studies. Married/partnered MI patients had higher HRQoL than unpartnered patients, but the associations with functional, symptom, and personal recovery outcomes and sex differences were less clear. Our findings inform better methodological approaches and standardized reporting to facilitate future research on these relationships.

The CONFIDENT study protocol: a randomized controlled trial comparing two methods to increase long-term care worker confidence in the COVID-19 vaccines

BackgroundClinical and real-world effectiveness data for the COVID-19 vaccines have shown that they are the best defense in preventing severe illness and death throughout the pandemic. However, in the US, some groups remain more hesitant than others about receiving COVID-19 vaccines. One important group is long-term care workers (LTCWs), especially because they risk infecting the vulnerable and clinically complex populations they serve. There is a lack of research about how best to increase vaccine confidence, especially in frontline LTCWs and healthcare staff. Our aims are to: (1) compare the impact of two interventions delivered online to enhanced usual practice on LTCW COVID-19 vaccine confidence and other pre-specified secondary outcomes, (2) determine if LTCWs’ characteristics and other factors mediate and moderate the interventions’ effect on study outcomes, and (3) explore the implementation characteristics, contexts, and processes needed to sustain a wider use of the interventions.MethodsWe will conduct a three-arm randomized controlled effectiveness-implementation hybrid (type 2) trial, with randomization at the participant level. Arm 1 is a dialogue-based webinar intervention facilitated by a LTCW and a medical expert and guided by an evidence-based COVID-19 vaccine decision tool. Arm 2 is a curated social media web application intervention featuring interactive, dynamic content about COVID-19 and relevant vaccines. Arm 3 is enhanced usual practice, which directs participants to online public health information about COVID-19 vaccines. Participants will be recruited via online posts and advertisements, email invitations, and in-person visits to care settings. Trial data will be collected at four time points using online surveys. The primary outcome is COVID-19 vaccine confidence. Secondary outcomes include vaccine uptake, vaccine and booster intent for those unvaccinated, likelihood of recommending vaccination (both initial series and booster), feeling informed about the vaccines, identification of vaccine information and misinformation, and trust in COVID-19 vaccine information provided by different people and organizations. Exploration of intervention implementation will involve interviews with study participants and other stakeholders, an in-depth process evaluation, and testing during a subsequent sustainability phase.DiscussionStudy findings will contribute new knowledge about how to increase COVID-19 vaccine confidence and effective informational modalities for LTCWs.Trial registrationNCT05168800 at ClinicalTrials.gov, registered December 23, 2021.

Effects of home-based cardiac telerehabilitation programs in patients undergoing percutaneous coronary intervention: a systematic review and meta-analysis

BackgroundRecent advances in telecommunications technology have raised the possibility of telehealth intervention delivering cardiac telerehabilitation, which may provide the efficacy of health services in patients after percutaneous coronary intervention (PCI). This study aimed to investigate the effects of home-based cardiac telerehabilitation (HBCTR) in patients undergoing PCI.MethodsWe performed a comprehensive search of the following electronic databases: PubMed, Cochrane Central, Web of Science, Embase, CNKI, and WANFANG. For the prespecified outcomes, the primary outcomes were results of physical function (the six-minute walking test, 6MWT) and quality of life (QoL) of the participants. The secondary outcomes were results of (1) blood pressure; (2) full lipid profile (3) reliable assessment of anxiety and depression in patients.ResultsAll studies were conducted between 2013 and 2022, and a total of 5 articles could be included in the quantitative meta-analysis. The results showed that there was a statistically significant difference between the HBCTR intervention group and the control group in 6WMT (MD 16.59, 95%CI 7.13 to 26.06, P = 0.0006), but there was no difference in QoL (SMD − 0.25, 95%CI − 1.63 to 1.13, P = 0.73). According to the fixed effects model, there was a statistically significant difference between the HBCTR group versus the control group (MD − 2.88, 95%CI − 5.19 to − 0.57, P = 0.01), but not in diastolic blood pressure. Likewise, significant improvements of triglycerides and in low-density lipoprotein cholesterol were observed in HBTCR groups, but no significant differences were observed regarding total cholesterol and high-density lipoprotein cholesterol.ConclusionThis systematic review and meta-analysis have proven that the HBCTR is one of the promisingly effective cardiac rehabilitation strategies that improve cardiorespiratory fitness and reduce cardiovascular disease risk factors. With the continuous improvement of the telerehabilitation network, it is expected to serve in clinical.

The impact of bedside wipes in multi-patient rooms: a prospective, crossover trial evaluating infections and survival

Multidrug-resistant organisms (MDROs) are prevalent on high-touch surfaces in multi-patient rooms. To quantify the impact of hanging single-use cleaning/disinfecting wipes next to each bed. Pre-specified outcomes were: (1) hospital-acquired infections (HAIs), (2) cleaning frequency, (3) MDRO room contamination, (4) new MDRO acquisitions, and (5) mortality. Clustered randomized crossover trial at Shamir Medical Center, Israel (October 2016 to January 2018). Clusters were randomly assigned to use for cleaning either single-use quaternary ammonium wipes (Clinell) or standard practices (reusable cloths and buckets with bleach). Six-month intervention periods were implemented in alternating sequence, separated by a washout period. Five high-touch surfaces were monitored by fluorescent markers. Study outcomes were compared between periods using generalized estimating equations, Poisson regression, and Cox proportional hazards models. Overall, 7725 patients were included (47,670 person-days), 3793 patients in rooms with intervention cleaning and 3932 patients in rooms with standard practices. During the intervention, there was no significant difference in HAI rates (incidence rate ratio: 1.6; 95% confidence interval (CI): 0.7-3.5; P= 0.3). However, in intervention rooms, the frequency of environmental cleaning was higher (odds ratio: 3.73; 95% CI: 2.0-7.1; P < 0.0001), MDRO environmental contamination rate was insignificantly lower (odds ratio: 0.7; 95% CI: 0.5-1.0; P= 0.06), new MDRO acquisition rate was lower (hazard ratio: 0.4; 95% CI: 0.2-1.0; P= 0.04), and in-hospital mortality rate was lower (incidence rate ratio: 0.8; 95% CI: 0.7-1.0; P= 0.03). Hanging single-use cleaning/disinfecting wipes next to each bed did not affect the HAI rates but did improve the frequency of cleaning, reduce MDRO environmental contamination, and was associated with reduced incidence of new MDRO acquisitions and reduced mortality. This is a feasible, recommended practice to improve patient outcomes in multi-patient rooms.

Long-Term Changes in Estimated Glomerular Filtration Rate in Left Ventricular Assist Device Recipients: A Longitudinal Joint Model Analysis.

Background Advanced kidney disease is often a relative contraindication to left ventricular assist device (LVAD) implantation because of concerns for poor outcomes including worsening kidney disease. Data are lacking on long-term changes and sex-based differences in estimated glomerular filtration rate (eGFR), with published data limited by potential bias introduced by the competing risks of death and heart transplantation. Methods and Results We conducted a longitudinal analysis of 288 adults receiving durable continuous-flow LVADs from January 2010 to December 2017 at a single center. A joint model was constructed to evaluate change in eGFR over 2 years, the prespecified primary outcome, adjusted for the competing risks of death and heart transplantation. Median baseline eGFR was 60 mL/min per 1.73 m2 (interquartile range 42-78). At 2 years, 74 patients died and 104 received a heart transplant. In unadjusted analysis, LVAD recipients had a modest initial increase in eGFR of ≈2 mL/min per 1.73 m2 within the first 6 months after implantation, followed by a decrease in eGFR below baseline values at 1 and 2 years. Men experienced an eGFR decline of 5 to 10 mL/min per 1.73 m2 over the first year which then stabilized, while women had an ≈5 mL/min per 1.73 m2 increase in eGFR within the first 6 months followed by decline towards baseline eGFR levels (interaction P=0.005). Conclusions Estimated GFR remains relatively stable in most patients following LVAD implantation. Larger studies are needed to investigate sex-based differences in eGFR and to evaluate eGFR trajectory and mortality in LVAD recipients with lower eGFR.

Abstract WP1: Tenecteplase Vs Alteplase For Large Vessel Occlusion Stroke: A Systematic Review And Meta-analysis

Introduction: Patients with large vessel occlusion stroke (LVO) benefit from thrombolysis before thrombectomy. Previous meta-analysis suggested superiority of tenecteplase over alteplase in achieving good clinical outcome at 3 months. Aim: We aimed to compare clinical outcomes after tenecteplase 0.25 mg/kg versus alteplase in patients with LVO. Methods: An experienced librarian searched PubMed and Scopus databases through July 13, 2022 for randomized controlled trials comparing tenecteplase with alteplase in patients with LVO. We included trials using 0.25 mg/kg tenecteplase dose, reporting blindly assessed pre-specified clinical outcomes at 3-4 months among patients with LVO. Two authors independently reviewed eligibility and extracted the data. We used RevMan 5.4 and random effect models with inverse variance weights to calculate odds ratios (OR) and 95% confidence intervals (CI). This systematic review is registered (CRD42022349414). Results: From 585 retrieved abstracts, 3 trials and 1 pooled secondary analysis involving 704 unique patients met the inclusion criteria. Among patients with LVO, tenecteplase 0.25mg/kg is not superior to alteplase in achieving good clinical outcome (defined as modified Rankin Scale [mRS] 0-2, OR 1.82 (95% CI 0.91-3.65, panel A); nor all-cause mortality, OR 0.75 (95% CI 0.49-1.13, panel B); while tenecteplase increases the odds of excellent outcome (mRS 0-1), OR 1.52 (95% CI 1.11-2.09, panel C), and odds of functional improvement (defined as a shift on the ordinal mRS), OR 1.54 (95% CI 1.07-2.20, panel D). High heterogeneity was present (I2 =70%) for the good clinical outcome. Conclusion: Tenecteplase is not superior over alteplase in achieving good clinical outcome. Tenecteplase, as compared to alteplase, increases the odds of functional improvement and excellent outcome. These findings support bridging tenecteplase in patients with LVO.
