The impact of pre-transplant respiratory virus detection on post-transplant outcomes in children undergoing hematopoietic cell transplantation.

BACKGROUND: Pre-transplant respiratory virus (RV) infections have been associated with negative transplant outcomes in adult hematopoietic cell transplantation (HCT) recipients. In the era of HCT delay due to high-risk RVs, we examined the impact of pre-transplant RV detection on transplant outcomes in a pediatric HCT recipients. METHODS: This retrospective cohort study included myeloablative allogeneic HCT recipients from 2010 to 2019. All patients were screened for RV at least once within 90 days before HCT using RT-PCR, regardless of symptoms. Post-transplant outcomes included days alive and out of hospital (DAOH) and progression to lower respiratory tract infection (LRTI). RESULTS: Among 310 patients, 134 had a RV detected in the 90 days prior to HCT. In univariable analysis, transplant factors including younger age, total body irradiation, umbilical cord blood transplantation, lymphocyte count less than 100/mm3, and HCT comorbidity index score ≥3, and viral factors including symptomatic infection, human rhinovirus (HRV) as a virus type, and symptomatic pre-transplant upper respiratory tract infection (URTI) were associated with fewer DAOH. In multivariable analysis, transplant factors remained significant, but not viral factors. There was a higher incidence of progression to post-transplant LRTI with the same pre-transplant RV if the last positive PCR before HCT was ≤30 days compared to >30 days (p=0.007). CONCLUSION: In the setting of recommending HCT delay for high-risk RVs, symptomatic URTI, including HRV infections, may lead to increased duration of hospitalization and early progression to LRTI when transplantation is performed within 30 days of the last positive PCR test.

Current and future advances in practice: aromatase inhibitor-induced arthralgia.

Aromatase inhibitors (AIs) have shown great success as adjuvant therapy for post-menopausal women with hormone receptor-positive breast cancers. AI-induced arthralgia (AIA) is a frequent AI toxicity contributing to non-adherence and discontinuation. This review aims to understand current knowledge of AIA. The mean incidence of AIA was 39.1% and the mean discontinuation of AI therapy due to AIA was 9.3%. Most of the AIAs were non-inflammatory. A shorter time since the last menstrual period and pre-existing joint pain were risk factors. Vitamin D3 supplementation may be a preventative measure and treatment with duloxetine, acupuncture and/or exercise is supported by large randomized controlled trials. There was consistent improvement in AIAs with switching to an alternate AI, and this could additionally allow continuation of cancer treatment with AI. Further research is needed to identify predictive biomarkers, better characterize AIA subcategories and study more reliable therapeutic options.

Finding Your Voice: A Large-Scale Nursing Training in Speaking up and Listening Skills.

BACKGROUND: Training in speaking up skills for nursing professionals provides the groundwork for promoting a culture of curiosity and inquiry. At the foundation of speaking up is psychological safety for team members to disagree, offer alternative ideas, and ask questions. METHOD: A large-scale training session, Finding Your Voice: Speaking Up & Listening Skills, was designed and delivered to 1,306 nurses at an academic medical center. RESULTS: Most participants reported that the session met the training goals (97%). There was an increase in participants' confidence in speaking up (pretraining 69% ± 19%; posttraining 73% ± 15%; p < .0001), and listening (pretraining 68% ± 19%; post-training 74% ± 15%; p < .0001). Leaders showed greater increases in confidence in listening and responding to nurses speaking up (leaders 5.6% vs. nonleaders 4.2%, p < .00001). CONCLUSION: Nurses benefited from an interactive educational experience by practicing strategies for speaking up and listening. [J Contin Educ Nurs. 202x;5x(x):xx-xx.].

Redirecting antibody responses from egg-adapted epitopes following repeat vaccination with recombinant or cell culture-based versus egg-based influenza vaccines.

Repeat vaccination with egg-based influenza vaccines could preferentially boost antibodies targeting the egg-adapted epitopes and reduce immunogenicity to circulating viruses. In this randomized trial (Clinicaltrials.gov: NCT03722589), sera pre- and post-vaccination with quadrivalent inactivated egg-based (IIV4), cell culture-based (ccIIV4), and recombinant (RIV4) influenza vaccines were collected from healthcare personnel (18-64 years) in 2018-19 (N = 723) and 2019-20 (N = 684) influenza seasons. We performed an exploratory analysis. Vaccine egg-adapted changes had the most impact on A(H3N2) immunogenicity. In year 1, RIV4 induced higher neutralizing and total HA head binding antibodies to cell- A(H3N2) virus than ccIIV4 and IIV4. In year 2, among the 7 repeat vaccination arms (IIV4-IIV4, IIV4-ccIIV4, IIV4-RIV4, RIV4-ccIIV4, RIV4-RIV4, ccIIV4-ccIIV4 and ccIIV4-RIV4), repeat vaccination with either RIV4 or ccIIV4 further improved antibody responses to circulating viruses with decreased neutralizing antibody egg/cell ratio. RIV4 also had higher post-vaccination A(H1N1)pdm09 and A(H3N2) HA stalk antibodies in year 1, but there was no significant difference in HA stalk antibody fold rise among vaccine groups in either year 1 or year 2. Multiple seasons of non-egg-based vaccination may be needed to redirect antibody responses from immune memory to egg-adapted epitopes and re-focus the immune responses towards epitopes on the circulating viruses to improve vaccine effectiveness.

Comprehensive profiling of social mixing patterns in resource poor countries: a mixed methods research protocol.

Background: Low-and-middle-income countries (LMICs) bear a disproportionate burden of communicable diseases. Social interaction data inform infectious disease models and disease prevention strategies. The variations in demographics and contact patterns across ages, cultures, and locations significantly impact infectious disease dynamics and pathogen transmission. LMICs lack sufficient social interaction data for infectious disease modeling. Methods: To address this gap, we will collect qualitative and quantitative data from eight study sites (encompassing both rural and urban settings) across Guatemala, India, Pakistan, and Mozambique. We will conduct focus group discussions and cognitive interviews to assess the feasibility and acceptability of our data collection tools at each site. Thematic and rapid analyses will help to identify key themes and categories through coding, guiding the design of quantitative data collection tools (enrollment survey, contact diaries, exit survey, and wearable proximity sensors) and the implementation of study procedures.We will create three age-specific contact matrices (physical, nonphysical, and both) at each study site using data from standardized contact diaries to characterize the patterns of social mixing. Regression analysis will be conducted to identify key drivers of contacts. We will comprehensively profile the frequency, duration, and intensity of infants' interactions with household members using high resolution data from the proximity sensors and calculating infants' proximity score (fraction of time spent by each household member in proximity with the infant, over the total infant contact time) for each household member. Discussion: Our qualitative data yielded insights into the perceptions and acceptability of contact diaries and wearable proximity sensors for collecting social mixing data in LMICs. The quantitative data will allow a more accurate representation of human interactions that lead to the transmission of pathogens through close contact in LMICs. Our findings will provide more appropriate social mixing data for parameterizing mathematical models of LMIC populations. Our study tools could be adapted for other studies.

Homogeneity- and Stoichiometry-Induced Electrical and Optical Properties of Cu-Se Thin Films by RF Sputtering Power.

P-type Cu-Se thin films were deposited on glass substrates at room temperature using radio frequency magnetron sputtering by a single multi-component CuSe2 target. When using a multi-component target, the impact of the sputtering power on the homogeneity and stoichiometry within the thin films should be investigated in the depth direction to demonstrate a secondary effect on the electrical and optical properties of the thin films. Systematic characterization of the Cu-Se thin films, including the morphology, microstructure, chemical composition, and depth-directional chemical bonding state and defect structure of the thin films, revealed that the sputtering power played an important role in the homogeneity and stoichiometry of the thin films. At very low and very high sputtering power levels, the Cu-Se thin films exhibited more deviations from stoichiometry, while an optimized sputtering power resulted in more homogenous thin films with improved stoichiometry across the entire thin film thickness in the X-ray photoelectron spectroscopy depth profile, despite showing Se deficiency at all depths. A rapid decrease in carrier concentration, indicating a reduction in the net effect of total defects, was obtained at the optimized sputtering power with less deviation from stoichiometry in the Cu-Se thin films and the closest stoichiometric ratio at an intermediate depth.

The minimally invasive approach to abdominal cerclage: indications, complications, and techniques for placement.

PURPOSE OF REVIEW: Laparoscopic abdominal cerclage placement has become the favored approach for management of refractory cervical insufficiency. There are special considerations with respect to surgical method, management of pregnancy loss, and delivery following placement. This review addresses current literature on transabdominal cerclage with a focus on up-to-date minimally invasive techniques. RECENT FINDINGS: Recent literature on abdominal cerclage has compared laparoscopic and open approaches, evaluated the effect of preconception placement on fertility, and explored the upper gestational limit for dilation and evacuation with an abdominal cerclage in situ . SUMMARY: The objective of this article is to help minimally invasive surgeons identify candidates for transabdominal cerclage placement, understand surgical risks, succeed in their laparoscopic approach, and appropriately manage patients postoperatively.

The effects of cognitive reappraisal and sleep on emotional memory formation.

Emotion regulation (i.e. either up- or down-regulating affective responses to emotional stimuli) has been shown to modulate long-term emotional memory formation. Further, research has demonstrated that the emotional aspects of scenes are preferentially remembered relative to neutral aspects (known as the emotional memory trade-off effect). This trade-off is often enhanced when sleep follows learning, compared to an equivalent period of time spent awake. However, the interactive effects of sleep and emotion regulation on emotional memory are poorly understood. We presented 87 participants with pictures of neutral or negative objects on neutral backgrounds paired with instructions to either increase or decrease their emotional response by altering personal relevance, or to passively view the stimuli. Following a 12 h period of sleep or wakefulness, participants were tested for their memory of objects and backgrounds separately. Although we replicated the emotional memory trade-off effect, no differences in the magnitude of the trade-off effect were observed between regulation conditions. Sleep improved all aspects of memory, but it did not preferentially benefit memory for emotional components of scenes. Irrespective of a period of sleep or wake following encoding, findings suggest emotion regulation during encoding did not influence memory for emotional items at a 12-hour delay.

Immunogenicity of High-Dose Egg-Based, Recombinant, and Cell Culture-Based Influenza Vaccines Compared With Standard-Dose Egg-Based Influenza Vaccine Among Health Care Personnel Aged 18-65 Years in 2019-2020.

Background: Emerging data suggest that second-generation influenza vaccines with higher hemagglutinin (HA) antigen content and/or different production methods may induce stronger antibody responses to HA than standard-dose egg-based influenza vaccines in adults. We compared antibody responses to high-dose egg-based inactivated (HD-IIV3), recombinant (RIV4), and cell culture-based (ccIIV4) vs standard-dose egg-based inactivated influenza vaccine (SD-IIV4) among health care personnel (HCP) aged 18-65 years in 2 influenza seasons (2018-2019, 2019-2020). Methods: In the second trial season, newly and re-enrolled HCPs who received SD-IIV4 in season 1 were randomized to receive RIV4, ccIIV4, or SD-IIV4 or were enrolled in an off-label, nonrandomized arm to receive HD-IIV3. Prevaccination and 1-month-postvaccination sera were tested by hemagglutination inhibition (HI) assay against 4 cell culture propagated vaccine reference viruses. Primary outcomes, adjusted for study site and baseline HI titer, were seroconversion rate (SCR), geometric mean titers (GMTs), mean fold rise (MFR), and GMT ratios that compared vaccine groups to SD-IIV4. Results: Among 390 HCP in the per-protocol population, 79 received HD-IIV3, 103 RIV4, 106 ccIIV4, and 102 SD-IIV4. HD-IIV3 recipients had similar postvaccination antibody titers compared with SD-IIV4 recipients, whereas RIV4 recipients had significantly higher 1-month-postvaccination antibody titers against vaccine reference viruses for all outcomes. Conclusions: HD-IIV3 did not induce higher antibody responses than SD-IIV4, but, consistent with previous studies, RIV4 was associated with higher postvaccination antibody titers. These findings suggest that recombinant vaccines rather than vaccines with higher egg-based antigen doses may provide improved antibody responses in highly vaccinated populations.

A Randomized Controlled Trial to Compare Immunogenicity to Cell-Based Versus Live-Attenuated Influenza Vaccines in Children.

BACKGROUND: Few studies have focused on the immune response to more recent influenza vaccine formulations such as cell-cultured inactivated influenza vaccine (ccIIV4) or live-attenuated influenza vaccine (LAIV4) in older children and young adults, or differences in immunoglobulin response using newer antibody landscape technology. METHODS: Participants ages 4-21 were randomized to receive ccIIV4 (n = 112) or LAIV4 (n = 118). A novel high-throughput multiplex influenza antibody detection assay was used to provide detailed IgG, IgA, and IgM antibody isotypes, along with hemagglutination inhibition levels (HAI), measured pre- and 28 days post-vaccination. RESULTS: The HAI and immunoglobulin isotype response to ccIIV4 was greater than LAIV4, with significant increases in IgG but not IgA or IgM. The youngest participants had the highest LAIV4 response. Prior LAIV4 vaccination was associated with a higher response to current season ccIIV4. Cross-reactive A/Delaware/55/2019(H1N1)pdm09 antibodies were present pre-vaccination and increased in response to ccIIV4, but not LAIV4. Immunoglobulin assays strongly correlated with and confirmed the findings of HAI titers to measure immune response. CONCLUSIONS: Age and prior season vaccination may play a role in the immune response in children and young adults to ccIIV4 and LAIV4. While immunoglobulin isotypes provide high-level antigen-specific information, HAI titers alone can provide a meaningful representation of day 28 post-vaccination response.

The power of emojis: The impact of a leader's use of positive emojis on members' creativity during computer-mediated communications.

The existing literature on emojis offers limited insights on the effects of using emojis in organizational settings, especially in the context of leader-member relationships. The current research examines how a leader's use of positive emojis can influence members' creative performance, a critical determinant of an organization's success and productivity. We find that a leader's use of positive emojis enhances members' creativity and that this effect is mediated by a decrease in members' perception of objectification by the leader. We further find that this impact of a leader's use of positive emojis on members' creativity is stronger when members have a higher level of relationship orientation. Contrary to the popular belief that the use of emojis in a work setting is inappropriate, our findings reveal that leaders' use of emojis has positive impacts on important workplace outcomes. These findings provide important guidelines on how to apply emojis to computer-mediated communications at work by demonstrating the circumstances in which positive consequences of using emojis occur.

Influenza Vaccine Effectiveness Among Children: 2011-2020.

BACKGROUND AND OBJECTIVES: Infants and children are at increased risk of severe influenza virus infection and its complications. Influenza vaccine effectiveness (VE) varies by age, influenza season, and influenza virus type/subtype. This study's objective was to examine the effectiveness of inactivated influenza vaccine against outpatient influenza illness in the pediatric population over 9 influenza seasons after the 2009 A(H1N1) pandemic. METHODS: During the 2011-2012 through the 2019-2020 influenza seasons at outpatient clinics at 5 sites of the US Influenza Vaccine Effectiveness Network, children aged 6 months to 17 years with an acute respiratory illness were tested for influenza using real-time, reverse-transcriptase polymerase chain reaction. Vaccine effectiveness was estimated using a test-negative design. RESULTS: Among 24 148 enrolled children, 28% overall tested positive for influenza, 3017 tested positive for influenza A(H3N2), 1459 for influenza A(H1N1)pdm09, and 2178 for influenza B. Among all enrollees, 39% overall were vaccinated, with 29% of influenza cases and 43% of influenza-negative controls vaccinated. Across all influenza seasons, the pooled VE for any influenza was 46% (95% confidence interval, 43-50). Overall and by type/subtype, VE against influenza illness was highest among children in the 6- to 59-month age group compared with older pediatric age groups. VE was lowest for influenza A(H3N2) virus infection. CONCLUSIONS: Analysis of multiple seasons suggested substantial benefit against outpatient illness. Investigation of host-specific or virus-related mechanisms that may result in differences by age and virus type/subtype may help further efforts to promote increased vaccination coverage and other influenza-related preventative measures.

Comparison of perioperative outcomes between bipolar sealing, ultrasonic shears and a hybrid device during laparoscopic gastrectomy for early gastric cancer: a prospective, multicenter, randomized study.

BACKGROUND: Although EBDs are essential for minimally invasive surgery, well-established prospective randomized studies comparing EBDs are scarce. This study aimed to compare the intraoperative inflammatory response and short-term surgical outcomes among different energy-based devices (EBDs) in laparoscopic distal gastrectomy (LDG). METHODS: Patients with clinical stage I gastric cancer scheduled for LDG at two different medical centers were prospectively randomized into three groups: ultrasonic shears (US), advanced bipolar (BP) and ultrasonic-bipolar hybrid (HB). The C-reactive protein (CRP) level, operation time, intraoperative blood loss (IBL), laboratory tests, cytokines (interleukin (IL)-6 and IL-10), hospital stay, and complication rate were analyzed. A novel semiquantitative measurement method using indocyanine green (ICG) and a near-infrared camera measured the amount of lymphatic leakage. RESULTS: The primary endpoint, the CRP level, was significantly lower in the BP (n = 60) group than in the US (n = 57) or HB (n = 57) group [9.03 ± 5.55 vs. 11.12 ± 5.02 vs. 12.67 ± 6.14, p = 0.001, on postoperative day (POD) 2 and 7.48 vs. 9.62 vs. 9.48, p = 0.026, on POD 4]. IBL was significantly lower in BP than in US or HB (26.3 ± 25.3 vs. 43.7 ± 42.0 vs. 34.9 ± 37.0, p = 0.032). Jackson-Pratt drainage triglycerides were significantly lower in BP than in US (53.6 ± 33.7 vs. 84.2 ± 59.0, p = 0.11; HB: 71.3 ± 51.4). ICG fluorescence intensity, operation time, laboratory results, cytokines, hospital stay, and complication rate were not significantly different among the 3 groups. CONCLUSION: BP showed a lower postoperative CRP level and less IBL than US and HB, suggesting less collateral thermal damage and better sealing function. Surgeons may consider this when selecting EBDs for laparoscopic surgery.

Clinical outcomes of gastric cancer surgery after liver transplantation.

Purpose: De novo malignancy is common after liver transplantation (LT); however, there are limited reports on the clinical outcomes of gastric cancer surgery after LT. Our study aimed to investigate the feasibility and safety of gastric cancer surgery after LT. Methods: Seventeen patients underwent gastric cancer surgery after LT at a single institution between January 2013 and June 2021. We retrospectively collected data on surgical complications, survival, and recurrence status of these cases. Results: Fifteen patients (88.2%) underwent curative gastrectomy, with 10 open distal (66.7%) and 5 laparoscopic distal (33.3%) gastrectomies. Surgical and severe complication rates were 3 of 15 (20.0%) and 1 of 15 (6.7%), respectively. There were no significant differences between laparoscopic (33.3%) and open surgery (66.7%) in terms of operation time and complication rate. No surgery-related mortalities occurred. Immunosuppressants could be maintained without difficulty, and no suspicious acute rejection was identified during the perioperative period. There was 1 recurrence after curative surgery (recurrence rate, 6.7%), and the 5-year cancer-specific survival rate after curative surgery was 93.3%. Conclusion: Laparoscopic gastrectomy can be safely done even after LT in terms of postoperative complications and graft safety.

Development and validity evidence for the intraprofessional conflict exercise: An assessment tool to support collaboration.

BACKGROUND: Effective collaboration is the foundation for delivering safe, high quality patient care. Health sciences curricula often include interprofessional collaboration training but may neglect conflicts that occur within a profession (intraprofessional). We describe the development of and validity evidence for an assessment of intraprofessional conflict management. METHODS AND FINDINGS: We designed a 22-item assessment, the Intraprofessional Conflict Exercise, to evaluate skills in managing intraprofessional conflicts based on a literature review of conflict management. Using Messick's validity framework, we collected evidence for content, response process, and internal structure during a simulated intraprofessional conflict from 2018 to 2019. We performed descriptive statistics, inter-rater reliability, Cronbach's alpha, generalizability theory, and factor analysis to gather validity evidence. Two trained faculty examiners rated 82 trainees resulting in 164 observations. Inter-rater reliability was fair, weighted kappa of 0.33 (SE = 0.03). Cronbach's alpha was 0.87. The generalizability study showed differentiation among trainees (19.7% person variance) and was highly reliable, G-coefficient 0.88, Phi-coefficient 0.88. The decision study predicted that using one rater would have high reliability, G-coefficient 0.80. Exploratory factor analysis demonstrated three factors: communication skills, recognition of limits, and demonstration of respect for others. Based on qualitative observations, we found all items to be applicable, highly relevant, and helpful in identifying how trainees managed intraprofessional conflict. CONCLUSIONS: The Intraprofessional Conflict Exercise provides a useful and reliable way to evaluate intraprofessional conflict management skills. It provides meaningful and actionable feedback to trainees and may help health educators in preparing trainees to manage intraprofessional conflict.

A Comparative Trial of Improving Care for Underserved Asian Americans Infected with Hepatitis B Virus.

BACKGROUND: Hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma (HCC). Asian Americans have the highest incidence and mortality rates of HCC among all US racial/ethnic groups. Inadequate monitoring and treatment of chronic hepatitis B contribute to poor health outcomes and increased healthcare costs among Asian Americans. AIMS: The goal of this study is to assess the effect of a patient-led strategy on chronic hepatitis B monitoring and treatment adherence specifically among Asian Americans with culturally tailored Patient Navigator-led Intervention. METHODS: From 2015 to 2018, 532 eligible participants living with chronic hepatitis B in the greater Philadelphia and New York city metropolitan areas were randomly assigned to either the intervention group or the control group. Generalized linear mixed-effects models were used to estimate the odds ratio (OR) for rates of doctor visits for chronic hepatitis B and rates of alanine aminotransferase testing for evidence of liver damage. RESULTS: Intervention group had higher rates of doctor visits than the control group at both 6-month (77.22% vs. 45.75%) and 12-month assessments (90.73% vs. 60.61%). Significantly more intervention group participants received ALT testing than control group participants at 6-month (52.90% vs. 25.10%) and 12-month (75.40% vs. 46.75%) follow-up. CONCLUSIONS: Culturally and linguistically appropriate intervention has strong effects on adherence to follow-up care among Asian American hepatitis B patients experiencing challenges to medication adherence and follow up care. These findings further identify opportunities for practical implementation of evidence-based intervention that could lead to reductions in disparities in chronic liver disease and liver cancer among high-risk, underserved populations.

Comparison between laparoscopic pylorus-preserving gastrectomy and laparoscopic distal gastrectomy for overweight patients with early gastric cancer.

Purpose: Laparoscopic pylorus-preserving gastrectomy (LPPG) has a nutritional advantage over laparoscopic distal gastrectomy (LDG), however, may be less beneficial in overweight patients in terms of weight loss. The purpose of this study was to compare LPPG and LDG in overweight patients with early gastric cancer. Methods: Clinicopathologic data of overweight patients (body mass index [BMI], ≥25 kg/m2) who underwent LPPG (n = 63) or LDG (n = 183) in 2016-2018 were retrospectively reviewed. In the LDG group, patients with Billroth-II anastomosis were separately grouped (LDG B-II, n = 66). Changes in BMI, hemoglobin, albumin, and total protein were compared among groups. Results: Changes in BMI were not significant different among groups. The LPPG group had significantly higher albumin than the LDG group at postoperative 6 months and 1 year. The LPPG group had higher total protein than the LDG group at postoperative 2 years. The LPPG group had a higher complication rate of Clavien-Dindo classification III or higher (20.6%) than the LDG group (8.2%, P = 0.007). However, after excluding pyloric stenosis, there was no significant difference among groups (LPPG vs. LDG, P = 0.290; LPPG vs. LDG B-II, P = 0.921). Conclusion: LPPG and LDG groups showed similar weight loss. However, the LPPG group had higher albumin and protein levels than the LDG group of overweight patients. Thus, it is not necessary to select LDG only for weight loss. LPPG may be selected as one option due to its potential nutritional benefit when pyloric stenosis is properly managed.

Relationship between Telework Experience and Presenteeism during COVID-19 Pandemic, United States, March-November 2020.

Persons with COVID-19-like illnesses are advised to stay home to reduce the spread of SARS-CoV-2. We assessed relationships between telework experience and COVID-19 illness with work attendance when ill. Adults experiencing fever, cough, or loss of taste or smell who sought healthcare or COVID-19 testing in the United States during March-November 2020 were enrolled. Adults with telework experience before illness were more likely to work at all (onsite or remotely) during illness (87.8%) than those with no telework experience (49.9%) (adjusted odds ratio 5.48, 95% CI 3.40-8.83). COVID-19 case-patients were less likely to work onsite (22.1%) than were persons with other acute respiratory illnesses (37.3%) (adjusted odds ratio 0.36, 95% CI 0.24-0.53). Among COVID-19 case-patients with telework experience, only 6.5% worked onsite during illness. Telework experience before illness gave mildly ill workers the option to work and improved compliance with public health recommendations to stay home during illness.

Influenza Vaccine Effectiveness Against Influenza A(H3N2)-Related Illness in the United States During the 2021-2022 Influenza Season.

BACKGROUND: In the United States, influenza activity during the 2021-2022 season was modest and sufficient enough to estimate influenza vaccine effectiveness (VE) for the first time since the beginning of the coronavirus disease 2019 pandemic. We estimated influenza VE against laboratory-confirmed outpatient acute illness caused by predominant A(H3N2) viruses. METHODS: Between October 2021 and April 2022, research staff across 7 sites enrolled patients aged ≥6 months seeking outpatient care for acute respiratory illness with cough. Using a test-negative design, we assessed VE against influenza A(H3N2). Due to strong correlation between influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, participants who tested positive for SARS-CoV-2 were excluded from VE estimations. Estimates were adjusted for site, age, month of illness, race/ethnicity, and general health status. RESULTS: Among 6260 participants, 468 (7%) tested positive for influenza only, including 440 (94%) for A(H3N2). All 206 sequenced A(H3N2) viruses were characterized as belonging to genetic group 3C.2a1b subclade 2a.2, which has antigenic differences from the 2021-2022 season A(H3N2) vaccine component that belongs to clade 3C.2a1b subclade 2a.1. After excluding 1948 SARS-CoV-2-positive patients, 4312 patients were included in analyses of influenza VE; 2463 (57%) were vaccinated against influenza. Effectiveness against A(H3N2) for all ages was 36% (95% confidence interval, 20%-49%) overall. CONCLUSIONS: Influenza vaccination in 2021-2022 provided protection against influenza A(H3N2)-related outpatient visits among young persons.

Safety of pylorus-preserving gastrectomy for gastric cancer combined with antral high-risk lesions: a comparison with endoscopic submucosal dissection.

BACKGROUND: Pylorus-preserving gastrectomy (PPG) is a surgical treatment option for cT1N0M0 gastric cancer located in the middle third of the stomach. However, data for the long-term post-PPG clinical outcomes related to metachronous gastric neoplasms (mGNs) in the residual stomach are currently lacking. Therefore, we aimed to evaluate the safety of PPG by focusing on mGNs. METHODS: In this single-center, retrospective study, we reviewed the data for 362 patients who underwent PPG with a 3-cm antral cuff and 139 who underwent endoscopic submucosal dissection (ESD) for middle-third gastric cancer between January 2013 and December 2015. The histopathologic features of the antrum in the ESD group, which could not be determined in the PPG group, were analyzed to investigate the risk factors for mGNs. The estimated and actual incidence of mGNs in the antrum were compared in the PPG group. RESULTS: The incidence of mGNs was 6.5% (9/139) in the ESD group. The presence of a synchronous adenoma (odds ratio [OR], 8.46; 95% confidence interval [CI], 1.55-46.34), carcinoma (OR, 15.71; 95% CI, 2.67-92.56) and moderate-to-severe intestinal metaplasia (OR, 9.77; 95% CI, 1.14-83.92) were associated with a higher risk of overall mGNs. However, when confined to the antrum, no significant association was observed between these factors and mGNs. In the ESD group, 2 of 9 mGNs (1.4%) were located at the 3-cm antral cuff. In the PPG group, both mGNs (0.6%) were located in the proximal remnant stomach. CONCLUSION: Pylorus-preserving gastrectomy was a safe therapeutic option with regard to the occurrence of metachronous adenomas or carcinomas in our series. Despite the low mGN incidence in the 3-cm antral cuff after PPG, the presence of synchronous neoplasms or moderate-to-severe intestinal metaplasia was a risk factor for mGNs in the ESD group; thus, further studies on longer antral cuffs with long-term follow-up are needed.
