Feasibility and acceptability of the community-based program: Plan Ahead.

OBJECTIVES: In this article, we assess the feasibility and acceptability and the effect of the Plan Ahead for community dwelling older adults. In addition, we investigated the effects of the program. In addition, we aimed to examine whether the completion of the specific Future Care Planning depended on the participants' competence level. METHODS: In this single group feasibility study, trained facilitators delivered the program to a sample of 234 community-residing older adults. Participants completed both pre, post assessments about the acceptability of the program and their completion of the recommended future care planning activities. RESULTS: Based on participant's report on the usefulness and satisfaction of the program after the completion of the program, we found that participants reported high levels of acceptance of the program. Participation rates also confirmed the feasibility of the program. In terms of effects of program implementation, statistically significant changes were noted for several outcomes, such as resource building and FCP activities. In particular, we found that these gains were particularly robust for participants in the low competence group. CONCLUSION: Pilot program results suggest the feasibility of a short community program enhancing proactive planning for future care needs among older adults residing in their community.

Emotion dysregulation and family functioning moderate family caregiving burden during the pandemic.

OBJECTIVES: Since the onset of COVID-19 pandemic, additional risk factors affecting family caregivers' mental health have arisen. Therefore, personal stress coping strategies and family dynamics became important factors in reducing the impact of the pandemic on family caregivers' mental health. The present research aimed to estimate the association between COVID-19 stressors and family caregiving burden. Moreover, moderating effects of emotion dysregulation and family functioning on this association were investigated. METHODS: This study analyzed data collected in April 2021 from 154 family caregivers (Mage = 38.79, SDage = 9.36, range = 22-64) recruited through Amazon's Mechanical Turk (MTurk). The impact of COVID-19 stressors on family caregiving burden was tested, and moderating impacts of emotion dysregulation and family functioning were also investigated. RESULTS: Both COVID-19 stress exposure and stress appraisal were positively associated with family caregiving burden. Emotion dysregulation and problematic family functioning were also positively associated with family caregiving burden. A significant moderating effect of emotion dysregulation was found, such that family caregivers with higher emotion dysregulation were likely to feel more caregiving burden when they experienced more COVID-19 stressors. SIGNIFICANCE OF RESULTS: The current research highlighted the role of emotion regulation in reducing the negative impact of COVID-19 stressors on family caregiving burden. The research also emphasizes the need for intervention programs to improve emotion regulation strategies to decrease family caregiving burden during the pandemic.

When suffering contradicts belief: measuring theodical struggling.

Global meaning systems help people make sense of their experiences, but suffering can violate global meaning and create distress. One type of potential violation is conflict between one's experience of suffering and one's deeply-held beliefs about God as loving, powerful, and just. The problem of theodicy-why an all-powerful and all-loving God would allow suffering-has long been an important theological and philosophical concern, but little is known about how theodicy plays out psychologically for religious individuals facing serious life difficulties. To address this issue within a specific religious tradition, Christianity, we drew upon philosophy, Christian theology, and psychology to develop the construct of theodical struggling. Through theological and philosophical input, we generated a 28-item pool and conducted 10 cognitive interviews with a diverse sample of Christian adults. In three consecutive online studies of Christian adult samples, we reduced the scale to 11 items through PCA, found a strong one-factor solution using EFA, and found support for the one-factor solution along with preliminary reliability and validity. This newly-developed Theodical Struggling Scale represents an important advance in understanding individuals' experiences of ruptures in their beliefs regarding God's goodness and paves the way for future research on this topic.

Effect of N-Methylation on Dopamine Surface Chemistry.

Dopamine (DA) surface chemistry has received significant attention because of its applicability in a wide range of research fields and the ability to graft functional molecules onto numerous solid surfaces. Various DA derivatives have been newly synthesized to identify key factors affecting the coating efficiency and to advance the coating system development. The oxidation of catechol into quinone followed by internal cyclization via the nucleophilic attack of primary amine is crucial for DA-based surface coating. Thus, it is expected that the amine group's nucleophilicity control directly affects the coating efficiency. However, it has not been systematically investigated, and most studies have been conducted with the focus on the transformation of amines into amides, despite such approaches decreasing the coating efficiency; the nitrogen in amides is less nucleophilic than that in free amines. In this study, we investigated the effect of N-alkylation on dopamine surface chemistry. N,N-Dimethyldopamine (DMDA) was newly synthesized, and the coating efficiency was systematically compared with DA and N-methyldopamine (MDA). DA N-monomethylation improved the coating rate by increasing the nitrogen nucleophilicity, whereas N,N-dimethylation dramatically decreased the DA surface coating property. In addition, MDA remained capable of universal surface coating and secondary reactions using the surface catechols. This study provides opportunities for developing coating materials with advanced functions and an improved coating rate.

Patient safety measurement tools used in nursing homes: a systematic literature review.

BACKGROUND: An increase in the number of older adults has highlighted the important issue of the safety of residents in nursing homes. This review aimed to review previous studies on patient safety of older adults living in nursing homes, analyze the tools used to measure it, and identify factors affecting patient safety of older adult residents in nursing homes. METHODS: A literature search was conducted using EMBASE, PubMed, CINHAL, and COCHRANE. The main search terms were "nursing home" or "skilled nursing facility" or "long-term care facility" and "patient safety." In total, 13,586 articles were identified. Two authors independently assessed the quality of each selected study using the Crowe Critical Appraisal Tool. RESULTS: Twenty-five studies were included in the analysis. There were a total of seven tools used to measure patient safety in nursing homes: the Nursing Home Survey on Patient Safety Culture (10 studies) and Hospital Survey on Patient Safety Culture (nine studies). Furthermore, the Nursing Home Survey on Patient Safety Culture-China, Safety Attitudes Questionnaire, Safety Attitudes Questionnaire in a Skilled Nursing Facility, Safety Attitudes Questionnaire-Ambulatory Version, and Modified Stanford Patient Safety Culture Survey Instrument were used in one study each. The most used tool among them was the Nursing Home Survey on Patient Safety Culture. Most tools used to measure patient safety in nursing homes were related to patient safety culture and employee attitudes. CONCLUSION: Organizational factors, such as the staff education system and the composition of appropriate personnel, should be strengthened to establish a patient safety culture in nursing homes, for which policy support is crucial.

Caregiving Outcomes of Sub/Urban and Rural Caregivers: The Powerful Tools for Caregivers Program.

OBJECTIVES: The research aimed to investigate the effectiveness of the Powerful Tools for Caregivers (PTC) program for rural caregivers. METHODS: A total of 160 caregivers participated in the program. Exploratory factor analysis was performed to identify latent caregiving outcomes. Paired samples t-tests were conducted to investigate changes in caregiving outcomes before and after the program. To examine geographical differences in the caregiving outcomes, independent samples t-tests were performed. Qualitative responses of the participants were also analyzed. RESULTS: Self-care and positive coping strategies were identified as latent caregiving outcomes. When comparing these two outcome scores before and after the program, the scores significantly improved. The changes in the caregiving outcomes of rural caregivers were greater than those of sub/urban caregivers. Although rural and sub/urban caregivers qualitatively reported similar themes, there were geographical differences in the percentages of caregivers reporting each theme. CONCLUSIONS: The PTC program was effective in improving self-care and positive coping strategies, but the effect of the program was more pronounced in rural areas. Our findings suggest that interventions focusing on self-care and positive coping strategies may beneficially impact rural caregivers. CLINICAL IMPLICATIONS: The PTC program appears promising to improve self-care strategies and enhance self-efficacy of rural caregivers.

Source Analysis and Effective Control of a COVID-19 Outbreak in a University Teaching Hospital during a Period of Increasing Community Prevalence of COVID-19.

BACKGROUND: South Korea has been experiencing a third wave of coronavirus disease 2019 (COVID-19) since mid-November 2020. Our hospital in Gwangju metropolitan city experienced a healthcare-associated COVID-19 outbreak early in the third wave. The first confirmed COVID-19 patient was a symptomatic neurosurgery resident with high mobility throughout the hospital. We analyzed the transmission routes of nosocomial COVID-19 and discussed infection control strategies. METHODS: We retrospectively analyzed the severe acute respiratory syndrome coronavirus 2 reverse transcription-polymerase chain reaction (RT-PCR) testing results according to time point and evaluated transmission routes. RESULTS: Since COVID-19 was first confirmed in a healthcare worker (HCW) on 11/13/2020, we performed RT-PCR tests for all patients and caregivers and four complete enumeration surveys for all HCWs. We detected three clusters of nosocomial spread and several sporadic cases. The first cluster originated from the community outbreak spot, where an asymptomatic HCW visited, which led to a total of 22 cases. The second cluster, which included patient-to-patient transmission, originated from a COVID-19 positive caregiver before diagnosis and the third cluster involved a radiologist and a banker. We took measures to isolate Building 1 of the hospital for 17 days and controlled the outbreak during a period of increasing community COVID-19 prevalence. Universal screening of all inpatients upon admission and resident caregivers was made mandatory and hospital-related employees are now screened monthly. CONCLUSION: Infection control strategies to prevent the nosocomial transmission of emerging infectious diseases must correspond with community disease prevalence. Our data reinforce the importance of multi-time point surveillance of asymptomatic HCWs and routine surveillance of patients and caregivers during an epidemic.

Red Algae-Derived Carrageenan Coatings for Marine Antifouling Applications.

We report a facile approach for the fabrication of a marine antifouling coating using the red algae-derived polysaccharide, carrageenan (CAR). Because CAR is hydrophilic and negatively charged, we hypothesized that it would form strong hydration layers upon adsorption onto solid surfaces, thereby exhibiting marine antifouling properties. Although various types of CAR can be used for marine antifouling, a universally applicable coating method has not yet been developed; thus, a systematic study on the marine antifouling property of CAR coating is lacking. Here, we fabricated a versatile CAR coating via ZrIV-mediated multiple cross-linking reactions between the sulfate groups of CAR and metal ions and successfully deposited κ-, ι-, and λ-CAR onto solid surfaces. Specifically, λ-CAR showed superior marine antifouling performance, as evidenced by the results of the marine diatom adhesion assays.

Four-week repeated dose oral toxicity study of KDS2010, a novel selective monoamine oxidase B inhibitor, in Sprague Dawley rats.

Repeated dose oral toxicity and toxicokinetic of KDS2010, a new drug for Parkinson's disease, was investigated after 4-week repeated oral administration at 30, 50, 75, or 100 mg/kg/day in rats. Body weight and body weight gain decreased in rats of both sexes in the 75 and 100 mg/kg groups, and food consumption was reduced in male rats of the 75 and 100 mg/kg male groups. Histological alterations were observed in the kidney (urothelial hyperplasia, inflammatory cell infiltration in the renal pelvis, tubular vacuolation/degeneration, basophilic tubules, and hyaline droplets in the proximal tubules) of the 75 and 100 mg/kg male groups and the 50 and 100 mg/kg female groups. The 75 and 100 mg/kg male groups showed adverse effect in the testes (degeneration/exfoliation of germ cells, seminiferous tubules atrophy) and epididymis (cellular debris, oligospermia). These changes were partially recovered after a 2-week recovery period. However, basophilic tubules and hyaline droplets in the proximal tubules in the kidney and germ cell degeneration/exfoliation in the testis were not recovered. In toxicokinetics study, systemic exposure to KDS2010 increased proportionally in both sexes by in a dose -dependent manner. In addition, repeated administration for 4 weeks led to increased tendency of systemic exposure in both sexes compared with that in Day 1. In conclusion, KDS2010 was shown to target the kidney and testis with a no-observed-adverse-effect level of 50 and 30 mg/kg/day for males and females, respectively.

Thirteen-week oral toxicity study of fermented ginseng, GBCK25, in Sprague-Dawley rats.

Ginseng (Panax ginseng) is commonly used in Asia as a medicinal herb. In particular, fermented ginseng, GBCK25, has been recently developed to increase ginsenoside absorption. It also has other beneficial biological effects such as hemodynamic and anti-inflammation functions. Here, we investigated the potential toxicity of GBCK25 in Sprague-Dawley rats following 13 weeks of GBCK25 treatment by oral gavage at doses of 250, 500, or 1000 mg/kg/day and reversible toxic effects over a 4-week recovery phase. Ten male and female rats per group were randomly allocated to the main toxicology groups and five male and female rats per group were allocated to the 0 and 1000 mg/kg/day recovery groups, respectively. There was no mortality; significant clinical toxicity or microscopic findings; and changes in body weight, food consumption, hematological parameters, serum biochemistry, or absolute and relative organ weights in any of the groups. In conclusion, there were no toxicological changes upon repeated oral gavage of GBCK25 at doses of 250, 500, or 1000 mg/kg/day in Sprague-Dawley rats over 13 weeks. The no-observed-adverse-effect level of GBCK25 was 1000 mg/kg/day in both sexes of Sprague-Dawley rat.

Identification of a novel SIRT7 inhibitor as anticancer drug candidate.

Sirtuins (SIRT1-7), a class of deacetylases, play major roles in DNA damage repair, aging, and metabolism in yeast and in mammals. SIRT7 is localized in the nucleolus. It regulates cellular processes, including genomic stability, rDNA transcription, and cell proliferation, and plays a role in tumorigenesis. SIRT7 deacetylates its substrates histone H3 (at lysine 18) and p53. p53, a tumor suppressor, induces apoptosis or cell cycle arrest and is stabilized by acetylation. p53 deacetylation at K382 by SIRT7 suppressed cancer cell growth by attenuating p53 activity. Therefore, identification of novel SIRT7 enzyme inhibitors is important. In this study, we found a novel inhibitor of SIRT7 (ID: 97491) that decreased SIRT7 activity in a dose-dependent manner. ID: 97491 induced expression of p53 and its acetylation by inhibited SIRT7. Moreover, ID: 97491 upregulated apoptotic effects through the caspase related proteins and inhibited cancer growth in vivo. The study results suggest that ID: 97491 can be a potential candidate to inhibit the deacetylase activity of SIRT7 and prevent tumor progression by increasing p53 stability through acetylation at K373/382.

Cell-Based Biosensors Based on Intein-Mediated Protein Engineering for Detection of Biologically Active Signaling Molecules.

Live-cell-based biosensors have emerged as a useful tool for biotechnology and chemical biology. Genetically encoded sensor cells often use bimolecular fluorescence complementation or fluorescence resonance energy transfer to build a reporter unit that suffers from nonspecific signal activation at high concentrations. Here, we designed genetically encoded sensor cells that can report the presence of biologically active molecules via fluorescence-translocation based on split intein-mediated conditional protein trans-splicing (PTS) and conditional protein trans-cleavage (PTC) reactions. In this work, the target molecules or the external stimuli activated intein-mediated reactions, which resulted in activation of the fluorophore-conjugated signal peptide. This approach fully valued the bond-making and bond-breaking features of intein-mediated reactions in sensor construction and thus eliminated the interference of false-positive signals resulting from the mere binding of fragmented reporters. We could also avoid the necessity of designing split reporters to refold into active structures upon reconstitution. These live-cell-based sensors were able to detect biologically active signaling molecules, such as Ca2+ and cortisol, as well as relevant biological stimuli, such as histamine-induced Ca2+ stimuli and the glucocorticoid receptor agonist, dexamethasone. These live-cell-based sensing systems hold large potential for applications such as drug screening and toxicology studies, which require functional information about targets.

A hot-water extract of Sanguisorba officinalis ameliorates endotoxin-induced septic shock by inhibiting inflammasome activation.

The inflammasome is a multiprotein signaling complex that mediates inflammatory innate immune responses through caspase 1 activation and subsequent IL-1ß secretion. However, because its aberrant activation often leads to inflammatory diseases, targeting the inflammasome holds promise for the treatment of inflammation-related diseases. In this study, it was found that a hot-water extract of Sanguisorba officinalis (HSO) suppresses inflammasome activation triggered by adenosine 5'-triphosphate, nigericin, microbial pathogens, and double stranded DNA in bone marrow-derived macrophages. HSO was found to significantly suppress IL-1ß production in a dose-dependent manner; this effect correlated well with small amounts of caspase 1 and little ASC pyroptosome formation in HSO-treated cells. The anti-inflammatory activity of HSO was further confirmed in a mouse model of endotoxin-induced septic shock. Oral administration of HSO reduced IL-1ß titers in the serum and peritoneal cavity, increasing the survival rate. Taken together, our results suggest that HSO is an inhibits inflammasome activation through nucleotide-binding domain and leucine-rich repeat pyrin domain 3, nucleotide-binding domain and leucine-rich repeat caspase recruitment domain 4 and absent in melanoma 2 pathways, and may be useful for treatment of inflammasome-mediated diseases.

Suppression of Hepatitis C Virus Genome Replication and Particle Production by a Novel Diacylglycerol Acyltransferases Inhibitor.

Diacylglycerol acyltransferases (DGATs) play a critical role in the biosynthesis of endogenous triglycerides (TGs) and formation of lipid droplets (LDs) in the liver. In particular, one member of DGATs, DGAT-1 was reported to be an essential host factor for the efficient production of hepatitis C virus (HCV) particles. By utilizing our previously characterized three different groups of twelve DGAT inhibitors, we found that one of the DGAT inhibitors, a 2-((4-adamantylphenoxy) methyl)-N-(furan-2-ylmethyl)-1H-benzo[d]imidazole-5-carboxam (10j) is a potent suppressor of both HCV genome replication and particle production. 10j was able to induce inhibition of these two critical viral functions in a mutually separate manner. Abrogation of the viral genome replication by 10j led to a significant reduction in the viral protein expression as well. Interestingly, we found that its antiviral effect did not depend on the reduction of TG biosynthesis by 10j. This suggests that the inhibitory activity of 10j against DGATs may not be directly related with its antiviral action.

Clinicopathological factors influencing the outcomes of surgical treatment in patients with T4a hypopharyngeal cancer.

BACKGROUND: The purpose of this study was to determine prognostic factors influencing outcomes of surgical treatment in patients with T4a hypopharyngeal cancer. METHODS: The present study enrolled 93 patients diagnosed with T4a hypopharyngeal cancer who underwent primary surgery between January 2005 and December 2015 at six medical centers in Korea. Primary tumor sites included pyriform sinus in 71 patients, posterior pharyngeal wall in 14 patients, and postcricoid region in 8 patients. Seventy-two patients received postoperative radio(chemo)therapy. RESULTS: Five-year disease-free survival (DFS) and disease-specific survival (DSS) rates were 38% and 45%, respectively. In univariate analysis, 5-year DFS was found to have significant and positive correlations with margin involvement (p < 0.001) and extracapsular spread (p = 0.025). Multivariate analysis confirmed that margin involvement (hazard ratio (HR): 2.81; 95% confidence interval (CI): 1.49-5.30; p = 0.001) and extracapsular spread (HR: 2.08; 95% CI: 1.08-3.99; p = 0.028) were significant factors associated with 5-year DFS. In univariate analysis, cervical lymph node metastasis (p = 0.048), lymphovascular invasion (p = 0.041), extracapsular spread (p = 0.015), and esophageal invasion (p = 0.033) were significant factors associated with 5-year DSS. In multivariate analysis, extracapsular spread (HR: 2.98; 95% CI: 1.39-6.42; p = 0.005) and esophageal invasion (HR: 2.87; 95% CI: 1.38-5.98; p = 0.005) remained significant factors associated with 5-year DSS. CONCLUSION: Margin involvement and extracapsular spread are factors influencing recurrence while extracapsular spread and esophageal invasion are factors affecting survival in patients with T4a hypopharyngeal cancer treated by primary surgery.

A hot water extract of Aralia cordata activates bone marrow-derived macrophages via a myeloid differentiation protein 88-dependent pathway and protects mice from bacterial infection.

In traditional Asian medicine, Aralia cordata (AC) is a known as a pain reliever and anti-inflammatory drug. Although several of its biological activities have been reported, the immunomodulatory effects of a hot water extract of AC (HAC) have not yet been described. The aim of this study was to investigate whether HAC modulates the activation of macrophages, which play important roles in innate immune responses against microbial pathogens, and if so, to determine the molecular mechanisms by which HAC mediates this process. It was found that HAC activates bone marrow-derived macrophages (BMDM) and increases amounts of nitric oxide and proinflammatory cytokines in a dose-dependent manner. In addition, HAC was found to induce phosphorylation of NF-κB and mitogen-activated protein kinases (MAPKs), including c-Jun N-terminal kinases, extracellular signal-regulated kinases and p38. Interestingly, these effects were absent in BMDM prepared from myeloid differentiation protein 88-knockout mice. Polysaccharides from HAC exerted stronger immunostimulatory effects than HAC itself. Furthermore, orally administered HAC clearly enhanced clearance of the intracellular pathogen Listeria monocytogenes by boosting innate immune responses. These results demonstrate that HAC exerts immunostimulatory effects through the TLR/MyD88 and NF-κB/MAPK signal transduction pathways.

Insights into an autonomously formed oxygen-evacuated Cu2O electrode for the selective production of C2H4 from CO2.

Electrochemical conversion of carbon dioxide (CO2) to small organic fuels (e.g. formate, methanol, ethylene, ethanol) is touted as one of the most promising approaches for solving the problems of climate change and energy security. In this study, we report the highly efficient electrochemical reduction of CO2 using cuprous oxide (Cu2O) electrodes to produce ethylene (C2H4) primarily. During CO2 electrolysis using electrodeposited Cu2O on a carbon electrode, we observe the transformation of a compact metal oxide layer to a metal oxide structure with oxygen vacant sites at the bulk region. In contrast to previous studies, our results clearly indicate that Cu2O remains at the surface of the catalyst and it efficiently catalyzes the conversion process of CO2 at low overpotential, exhibiting a high selective faradaic efficiency of over 20% towards C2H4 formation even in long-term electrolysis.

Electrocatalytic Production of C3-C4 Compounds by Conversion of CO2 on a Chloride-Induced Bi-Phasic Cu2O-Cu Catalyst.

Electrocatalytic conversion of carbon dioxide (CO2) has recently received considerable attention as one of the most feasible CO2 utilization techniques. In particular, copper and copper-derived catalysts have exhibited the ability to produce a number of organic molecules from CO2. Herein, we report a chloride (Cl)-induced bi-phasic cuprous oxide (Cu2O) and metallic copper (Cu) electrode (Cu2OCl) as an efficient catalyst for the formation of high-carbon organic molecules by CO2 conversion, and identify the origin of electroselectivity toward the formation of high-carbon organic compounds. The Cu2OCl electrocatalyst results in the preferential formation of multi-carbon fuels, including n-propanol and n-butane C3-C4 compounds. We propose that the remarkable electrocatalytic conversion behavior is due to the favorable affinity between the reaction intermediates and the catalytic surface.

Remote Control of Energy Transformation-Based Cancer Imaging and Therapy.

Cancer treatment requires precise tumor-specific targeting at specific sites that allows for high-resolution diagnostic imaging and long-term patient-tailorable cancer therapy; while, minimizing side effects largely arising from non-targetability. This can be realized by harnessing exogenous remote stimuli, such as tissue-penetrative ultrasound, magnetic field, light, and radiation, that enable local activation for cancer imaging and therapy in deep tumors. A myriad of nanomedicines can be efficiently activated when the energy of such remote stimuli can be transformed into another type of energy. This review discusses the remote control of energy transformation for targetable, efficient, and long-term cancer imaging and therapy. Such ultrasonic, magnetic, photonic, radiative, and radioactive energy can be transformed into mechanical, thermal, chemical, and radiative energy to enable a variety of cancer imaging and treatment modalities. The current review article describes multimodal energy transformation where a serial cascade or multiple types of energy transformation occur. This review includes not only mechanical, chemical, hyperthermia, and radiation therapy but also emerging thermoelectric, pyroelectric, and piezoelectric therapies for cancer treatment. It also illustrates ultrasound, magnetic resonance, fluorescence, computed tomography, photoluminescence, and photoacoustic imaging-guided cancer therapies. It highlights afterglow imaging that can eliminate autofluorescence for sustained signal emission after the excitation.

Vaccine Uptake and Perspectives Among Latina Immigrant Mothers in Rural Communities in a Midwestern State.

PURPOSE: Examine the prevalence of and characteristics related to COVID-19 vaccine uptake. DESIGN: Quantitative and qualitative data collected at two-time points via phone interviews. SETTING: Rural Midwestern communities. SAMPLE: 109 Latina mothers with incomes < 185% FPL, at least one child < age 12 recruited from a Midwestern state based on two previous studies. MEASURES: Mothers responded to the following variables through a survey: Vaccine uptake measured by responses to, Have you received a vaccination shot for COVID-19. Tested predictors of vaccine uptake included: income, gender, education, immigration status, confidence in vaccine, belief the pandemic is over). Mothers' perspectives regarding the vaccine explored via responses to Why haven't you received COVID-19 vaccine?. ANALYSIS: Binary logistic regression analysis was conducted. Demographic variables and attitudes toward the vaccine served as predictors of mothers' vaccine uptake. Qualitative data were analyzed to shed light on mothers' perspectives on receiving the vaccine. RESULTS: Mother's confidence in the vaccine predicted vaccine uptake in 2021 (aOR=1.332, 95% CI: 1.07-1.65) and 2022 (aOR=1.48, 95%CI: 1.11-1.97). In 2021, income also predicted vaccine uptake (aOR=1; 95% CI: 1-1.002). Overarching themes: "vaccination is not necessary","mistrust of the vaccine", and "vaccine as protector". CONCLUSION: Vaccinated mothers viewed the vaccine as a protection from being infected or gravely ill. For unvaccinated mothers, messages are needed that communicate the vaccine can protect them from virus transmission from household members who unknowingly are infected, as well as from different virus strains.
