Cervical Myelopathy and Social Media: Mixed Methods Analysis.

BACKGROUND: Degenerative cervical myelopathy (DCM) is a progressive neurologic condition caused by age-related degeneration of the cervical spine. Social media has become a crucial part of many patients' lives; however, little is known about social media use pertaining to DCM. OBJECTIVE: This manuscript describes the landscape of social media use and DCM in patients, caretakers, clinicians, and researchers. METHODS: A comprehensive search of the entire Twitter application programing interface database from inception to March 2022 was performed to identify all tweets about cervical myelopathy. Data on Twitter users included geographic location, number of followers, and number of tweets. The number of tweet likes, retweets, quotes, and total engagement were collected. Tweets were also categorized based on their underlying themes. Mentions pertaining to past or upcoming surgical procedures were recorded. A natural language processing algorithm was used to assign a polarity score, subjectivity score, and analysis label to each tweet for sentiment analysis. RESULTS: Overall, 1859 unique tweets from 1769 accounts met the inclusion criteria. The highest frequency of tweets was seen in 2018 and 2019, and tweets decreased significantly in 2020 and 2021. Most (888/1769, 50.2%) of the tweets' authors were from the United States, United Kingdom, or Canada. Account categorization showed that 668 of 1769 (37.8%) users discussing DCM on Twitter were medical doctors or researchers, 415 of 1769 (23.5%) were patients or caregivers, and 201 of 1769 (11.4%) were news media outlets. The 1859 tweets most often discussed research (n=761, 40.9%), followed by spreading awareness or informing the public on DCM (n=559, 30.1%). Tweets describing personal patient perspectives on living with DCM were seen in 296 (15.9%) posts, with 65 (24%) of these discussing upcoming or past surgical experiences. Few tweets were related to advertising (n=31, 1.7%) or fundraising (n=7, 0.4%). A total of 930 (50%) tweets included a link, 260 (14%) included media (ie, photos or videos), and 595 (32%) included a hashtag. Overall, 847 of the 1859 tweets (45.6%) were classified as neutral, 717 (38.6%) as positive, and 295 (15.9%) as negative. CONCLUSIONS: When categorized thematically, most tweets were related to research, followed by spreading awareness or informing the public on DCM. Almost 25% (65/296) of tweets describing patients' personal experiences with DCM discussed past or upcoming surgical interventions. Few posts pertained to advertising or fundraising. These data can help identify areas for improvement of public awareness online, particularly regarding education, support, and fundraising.

Main title - Socio-economic effects on informal caregivers of long-term hospitalized adult patients: A cross-sectional study.

Introduction: A significant proportion of patients are being treated at hospitals in the government sector in Sri Lanka. Informal caregivers play a major role in taking care of hospitalized surgical patients while facing physical, social, and psychological challenges. Objective: To describe the socio-economic effects on informal caregivers of long-term hospitalized adult patients. Methods: A cross-sectional descriptive study was conducted among 202 informal caregivers of long-term hospitalized patients in a tertiary care hospital in Sri Lanka, using an interviewer-administered questionnaire. Sociodemographic assessment of both caregiver and care recipient, the health status of the care recipient, effects on social life, and economic aspect of informal caregiver were assessed. Results: Most of the caregivers were married (n=164, 81.2%), first degree relative of the care receiver (n=139, 68.8%), employed (n=115, 56.9%) and sole caregivers (n=130, 64.4%). Four out of 5 caregivers (n=181, 89.6%) showed moderate to severe socio-economic maladaptation. Increasing age (p=0.00), marital status (p=0.00) and sole caregiving (p=0.01) are significantly associated with the level of maladaptation. Conclusion: Moderate to severe levels of maladaptation is present among a substantial number of informal caregivers of long-term hospitalized patients. Sole caregiving is one of the contributing factors and can be addressed by adequate formal caregivers appointed by health care authorities or from voluntary services to minimize informal caregiver burnout.

A Caretaker Acute Stress Paradigm: Effects on behavior and physiology of caretaker and infant.

While experimental stress paradigms of infants (arm restraint; the Still-Face) are powerful tools for infant research, no study has experimentally stressed mothers to observe its independent effects on infant stress regulation. Extant caretaker/maternal stress studies essentially are correlational and confounded by other conditions (e.g., depression). Here, we present a standard procedure, the Caregiver Acute Stress Paradigm (CASP), for stressing mothers during en face interactions with their infants. We hypothesized that infants of the stressed mothers would be more distressed than infants of non-stressed mothers. A total of 106 four-month-old infants and their mothers were randomly assigned to the experimental stress or non-stress manipulation. Confirming our hypothesis, infants of the stressed mothers were significantly more likely to become distressed and require terminating the procedure. While objective ratings of maternal behavior showed no difference between groups, mother in the stress condition self-rated the episode following the caretaker stress significantly lower than mothers in the non-stress group. The self-ratings in the maternal stress-group were reflected in infant cortisol. The findings indicate that CASP is an effective experimental paradigm for exploring the independent effects of an acute stress on caretakers, including effects of conditions, such as poverty or mental illness.

Parent's food preference and its implication for child malnutrition in Dabat health and demographic surveillance system; community-based survey using multinomial logistic regression model: North West Ethiopia; December 2017.

BACKGROUND: A Shortage or excessive intake of the nutrient is malnutrition; affecting every aspect of human beings. Malnutrition at childhood has long-lasting and multiple effects. In Ethiopia significant numbers of children were suffering from malnutrition that might be associated with parents' food preference; the fact not yet investigated. Therefore the aim of this study was to assess parents' food preferences and its implication for child malnutrition. METHODS: The study was conducted among 7150 mothers/caretakers in Dabat demographic and health surveillance site. Data were collected by experienced data collectors working for the surveillance centers after extensive training. A multinomial logistic regression model was fitted to determine the effect of factors on the dependent variable and model fitness was checked using a likelihood ratio test. RESULTS: About 62.55% of mothers/caretakers prefer to feed children with a family and 16.45% of them prefer to feed children with a specific type of food. Mothers/caretakers who introduce semisolid food after 6 months 2.34(1.50-3.96) were times more likely prefer to feed with family food for their children than a balanced diet. Regarding the specific type of food preference mothers who introduce semisolid food after 6 months and those obtain food from the market were 6.53(3.80-11.24) and 4.38(3.45-5.56) times more likely to prefer to feed specific types of than balanced diet respectively. CONCLUSION: Food preference had contributed to the increased and persistent magnitude of child malnutrition as 62.55% of mothers prefer to feed children with family and only 21% of them prefer to feed a balanced diet for under-five children. Therefore we recommended integration of child dietary diversity, acceptability and safety counseling session for mothers visiting health institutions for child vaccination, ANC and PNC services.

Continuous Non-invasive finger cuff CareTaker® comparable to invasive intra-arterial pressure in patients undergoing major intra-abdominal surgery.

BACKGROUND: Despite increased interest in non-invasive arterial pressure monitoring, the majority of commercially available technologies have failed to satisfy the limits established for the validation of automatic arterial pressure monitoring by the Association for the Advancement of Medical Instrumentation (AAMI). According to the ANSI/AAMI/ISO 81060-2:2013 standards, the group-average accuracy and precision are defined as acceptable if bias is not greater than 5 mmHg and standard deviation is not greater than 8 mmHg. In this study, these standards are used to evaluate the CareTaker® (CT) device, a device measuring continuous non-invasive blood pressure via a pulse contour algorithm called Pulse Decomposition Analysis. METHODS: A convenience sample of 24 patients scheduled for major abdominal surgery were consented to participate in this IRB approved pilot study. Each patient was monitored with a radial arterial catheter and CT using a finger cuff applied to the contralateral thumb. Hemodynamic variables were measured and analyzed from both devices for the first thirty minutes of the surgical procedure including the induction of anesthesia. The mean arterial pressure (MAP), systolic and diastolic blood pressures continuously collected from the arterial catheter and CT were compared. Pearson correlation coefficients were calculated between arterial catheter and CT blood pressure measurements, a Bland-Altman analysis, and polar and 4Q plots were created. RESULTS: The correlation of systolic, diastolic, and mean arterial pressures were 0.92, 0.86, 0.91, respectively (p < 0.0001 for all the comparisons). The Bland-Altman comparison yielded a bias (as measured by overall mean difference) of -0.57, -2.52, 1.01 mmHg for systolic, diastolic, and mean arterial pressures, respectively with a standard deviation of 7.34, 6.47, 5.33 mmHg for systolic, diastolic, and mean arterial pressures, respectively (p < 0.001 for all comparisons). The polar plot indicates little bias between the two methods (90%/95% CI at 31.5°/52°, respectively, overall bias = 1.5°) with only a small percentage of points outside these lines. The 4Q plot indicates good concordance and no bias between the methods. CONCLUSIONS: In this study, blood pressure measured using the non-invasive CT device was shown to correlate well with the arterial catheter measurements. Larger studies are needed to confirm these results in more varied settings. Most patients exhibited very good agreement between methods. Results were well within the limits established for the validation of automatic arterial pressure monitoring by the AAMI.

Knowledge, perception, and management skills of mothers with under-five children about diarrhoeal disease in indigenous and resettlement communities in Assosa District, Western Ethiopia.

As primary caregiver to under-five children in Ethiopia, mothers' knowledge, perception, and management skills are important to minimize the effects of morbidity and mortality associated with diarrhoeal diseases. A community-based comparative cross-sectional study was conducted in Abramo and Megele 37 kebeles (the last administration division) in Assosa district of western Ethiopia in July 2010. Quantitative data were obtained by a structured questionnaire from 232 randomly-selected mothers having children aged less than five years regarding their knowledge, perception, and management. Qualitative data were also collected by arranging four focus group discussions involving mothers from the two communities. The prevalence of diarrhoeal diseases among under-five children was 33.2%, and the knowledge of mothers about the causes, transmission, and prevention of diarrhoea in the study area was 37.5%. The prevalence of diarrhoeal disease was higher in the settlement area whereas mothers' knowledge was better in the indigenous community; 62.9% of mothers were categorized as having good attitude on causes, transmission, and prevention of diarrhoeal disease. Community water source, water storage container, and knowledge of mothers remained a strong predictor of diarrhoeal morbidity after conducting logistic regression analysis (OR=8.4, CI 3.59-31.85; OR=2.2, CI 1.02-4.89; and OR=3.62, CI 1.23-4.71 respectively). Diarrhoeal morbidity was high in the study areas. On the contrary, knowledge and attitude of mothers, recognizing the danger sign of dehydration due to diarrhoea, and the prevention and management of childhood diarrhoeal diseases were not adequate. Information, education and communication strategy may help increase the knowledge and create positive attitude among mothers regarding the cause, prevention, and management of diarrhoea.

A Review of the Literature on the Multiple Forms of Stigmatization of Caregivers of Children with Autism Among Ethnic Minority Groups.

Multiple forms of stigmatization are experienced by caregivers of children with autism among ethnic minority (EM) groups in various countries. Such forms of stigmatization can lead to delayed assessment and services for mental health among children and caregivers. This review identified the research literature on the types of stigmatization experienced by caregivers of children with autism with an EM background. A total of 19 studies published after 2010 (i.e., 12 from the USA, 2 from the UK, 1 from Canada, and 1 from New Zealand) of caregivers of 20 ethnicities were identified and reviewed, and their reporting qualities systematically also assessed. Four main themes: (1) self-stigma, (2) social stigma, (3) stigma towards EM parents of children on the autism spectrum, and (4) service utilization stigma, and nine sub-themes were identified. The discrimination experienced by caregivers were extracted, synthesized, and further discussed. While the reporting quality of the studies included is good, the depth of the understanding of this under-researched yet important phenomenon is very limited. The multiple forms of stigmatization experiences are complex, and it may be difficult to disentangle whether the causes of stigmatization were autism and/or EM related, and the types of stigmatization can vary enormously among different ethnic groups in different societies. More quantitative studies are needed to quantify the impacts of multiple forms of stigmatization on families of children with autism in EM groups so that more socially inclusive support for caregivers with an EM background in host countries can be developed.

A Voice-Activated Device Exercise and Social Engagement Program for Older Adult-Care Partner Dyads: Pilot Clinical Trial and Focus Group Study Evaluating the Feasibility, Use, and Estimated Functional Impact of EngAGE.

BACKGROUND: Maintaining exercise is essential for healthy aging but difficult to sustain. EngAGE is a socially motivated exercise program delivered over a voice-activated device that targets older adult-care partner dyads. OBJECTIVE: This 10-week pilot study aimed to assess EngAGE feasibility and use, obtain user experience feedback, and estimate potential impact on function. METHODS: In total, 10 older adults aged ≥65 years were recruited from an independent living residence together with their self-identified care partners. EngAGE delivered National Institute on Aging Go4Life exercises to older adults daily, while care partners received progress reports and prompts to send encouraging messages that were read aloud by the device to the older adult. Older adults' use was tracked, and physical function was assessed at baseline and follow-up. Follow-up focus group data provided qualitative feedback. RESULTS: On average, participants completed 393.7 individual exercises over the 10-week intervention period or 39.4 exercises/wk (range 48-492, median 431, IQR 384-481, SD 112.4) without injury and used EngAGE on an average of 41 of 70 days or 4.1 d/wk (range 7-66, median 51, IQR 23-56, and SD 21.2 days). Mean grip strength increased nonsignificantly by 1.3 kg (preintervention mean 26.3 kg, SD 11.0; postintervention mean 27.6 kg, SD 11.6; P=.34), and 4 of 10 participants improved by a minimal clinically important difference (MCID) of 2.5 kg. Further, the time for 5-repeated chair stands significantly reduced by 2.3 seconds (preintervention mean 12, SD 3.6 s; postintervention mean 9.7, SD 2.7 s; P=.02), and 3 of 9 participants improved by an MCID of -2.3 seconds. Furthermore, 3-meter usual walk performance was brisk at baseline (mean 2.1, SD 0.4 s) and decreased by 0.1 seconds (postintervention 2, SD 0.4 s; P=.13), although 5 of 9 participants improved by a MCID of 0.05 m/s. Qualitative results showed perceived benefits, favored program features, and areas for improvement. CONCLUSIONS: We present a pilot study of a new voice-activated device application customized to older adult users that may serve as a guide to other technology development for older adults. Our pilot study served to further refine the application and to inform a larger trial testing EngAGE's impact on functional outcomes, a necessary step for developing evidence-based technology tools.

Scatter Radiation Distribution to Radiographers, Nearby Patients and Caretakers during Portable and Pediatric Radiography Examinations.

Scatter radiation from portable and pediatric X-rays could pose a risk to radiographers, nearby patients, and caretakers. We aim to evaluate the spatial scatter radiation distribution to the radiographers, nearby patients, and caretakers during common projections in portable and pediatric X-rays. We evaluated the three-dimensional scatter dose profiles of four and three commonly used portable and pediatric X-ray projections, respectively, by anthropomorphic phantoms and scatter probes. For portable X-ray, the AP abdomen had the highest scatter radiation dose recorded. Radiographer scatter radiation doses were 177 ± 8 nGy (longest cord extension) and 14 ± 0 nGy (hiding behind the portable X-ray machine). Nearby patient scatter radiation doses were 3323 ± 28 nGy (40 cm bed distance), 1785 ± 50 nGy (80 cm bed distance), and 580 ± 42 nGy (160 cm bed distance). The AP chest and abdomen had the highest scatter radiation dose in pediatric X-rays. Caretaker scatter radiation doses were 33 ± 1 nGy (50 cm height) and 659 ± 7 nGy (140 cm height). Although the estimated lens doses were all within safe levels, the use of shielding and caution on dose estimation by inverse square law is suggested to achieve the ALARA principle and dose optimization.

Severity of frailty using modified Thai frailty index, social factors, and prediction of mortality among community-dwelling older adults in a middle-income country.

Background: Frailty has been increasingly recognized as a public health problem for aging populations with significant social impact, particularly in low- and middle-income countries. We aimed to develop a modified version of the Thai Frailty Index (TFI) and explore the association between different frailty statuses, socioeconomic factors, and mortality in community-dwelling older people from a middle-income country. Methods: The data from participants aged ≥60 years in the Fourth Thai National Health Examination Survey were used to construct the 30-item TFI. Cutoff points were created based on stratum-specific likelihood ratio. TFI ≤ 0.10 was categorized as fit, 0.10-0.25 as pre-frail, 0.25-0.45 as mildly frail, and >0.45 as severely frail. The association of frailty status with mortality was examined using Cox proportional hazard models. Findings: Among 8,195 older adults with a mean age of 69.2 years, 1,284 died during the 7-year follow-up. The prevalence of frailty was 16.6%. The adjusted hazard ratio (aHR) for mortality in pre-frail was 1.76 (95% CI = 1.50-2.07), mildly frail 2.79 (95% CI = 2.33-3.35), and severely frail 6.34 (95% CI = 4.60-8.73). Having a caretaker in the same household alleviated mortality risk for severely frail participants with an aHR of 2.93 (95% CI = 1.92-4.46) compared with an aHR of 6.89 (95% CI = 3.87-12.26) among those living without a caretaker. Interpretation: The severity of frailty classified by the modified TFI can predict long-term mortality risk for community-dwelling older adults. Identification of severely frail older people to provide appropriate care might alleviate mortality risk. Our findings can inform policymakers to appropriately allocate services in a resource-limited setting.

Coping strategies and their associated factors among caregivers of patients with schizophrenia in Kuantan, Malaysia.

Background: It is essential for caregivers of schizophrenia patients to have effective coping mechanisms to deal with their own mental health. However, research on the factors that contribute to the coping mechanisms of caregivers is limited. The purpose of this study is to investigate the use of coping strategies and their correlations to socio-demographic features, psychological distress, and social support among the caregivers of patients with schizophrenia. Method: Through the convenience sampling method, 331 caregivers of patients with schizophrenia participated in this cross-sectional study. The respondents comprised caregivers who had attended an outpatient psychiatric clinic, providing the socio-demographic data. The study involves three instruments: the Kessler's Psychological Distress (K10); the Multidimensional Scale of Perceived Social Support (MSPSS); and the Brief-COPE. Findings: Using multivariable analysis, psychological distress was identified as a substantial independent predictor of emotion-focused, problem-focused, and avoidance coping strategies. Good social support was linked to the usage of problem-focused and emotion-focused coping strategies. Conclusion: It has been demonstrated that good social support and psychological distress are associated with coping strategies. More prospective and qualitative research is required to determine how coping strategies will be able to assist Malaysian caregivers to develop a more holistic approach to treating patients with schizophrenia.

Varying Degrees of Animal Reification by Stakeholders in Experimental Research.

The attitude towards animals in research depends on both the role of the stakeholder and their personal characteristics. Most studies on the subject have been carried out on stakeholders from biomedical research institutes with comparatively few sociological studies on stakeholders from agricultural research centers. Previous findings suggest that animal caretakers at agricultural research centers felt undervalued by the hierarchy, and that animal reification was present in the sector. This may indicate that a lack of consideration for the animal subjects correlates with an inadequate sensitivity towards humans. Since these findings were published twenty years ago, there has been an increasing emphasis on the importance and actions of ethics committees in research, animal welfare bodies, and public concern for animals, which may have impacted the current perspective. To better understand current degrees of animal reification amongst stakeholders of agricultural research, we conducted semi-directive interviews at a leading agricultural research institute in France (INRAE). The interviews targeted both animal caretakers and researchers who were involved in the study of infectious diseases in livestock, or the behavior of horses and quails. After having transcribed the recorded interviews into text, semi-automatized analyses were carried out to categorize them into distinct groups, from which the most characteristic words and sentences were extracted. Three groups of stakeholders were identified: (i) animal caretakers involved in invasive infectious disease research; (ii) animal caretakers involved in behavioral research; and (iii) researchers. The findings show that animal caretakers felt acknowledged by their hierarchy. It is possible the increased skill criteria for people recruited into this position over the years, combined with greater prospects for continuous learning and development in the profession, may have fostered a more respectful regard across the hierarchy. The animal caretakers clearly expressed that their primary objective was to successfully execute the research protocols and that the animals were viewed as prototypes for research, with which they could, on occasion, develop a bond with. The bond was more important for animal caretakers involved in behavioral studies than for those involved in the study of infectious diseases, where invasive biological sampling and restraining of the animals is required. Researchers prioritized the procurement of robust data to test hypotheses, analyze phenomena, and publish their results. Their concern for the animals rather reflected the views of the general public opposed to thought-out personal opinions on the matter; this is possibly due to their comparatively limited interaction with the animals. They considered the animals in abstract terms that were indicative of reification. This study concludes that animal reification is still present, albeit to varying degrees amongst the stakeholders.

Soluble urokinase-type plasminogen activator receptor (suPAR) is elevated in caregivers of patients with parkinsonism.

Caregivers are integral to the care of those with neurological disorders such as Parkinson's Disease (PD), but are often burdened by stress, anxiety, and depression. Previous research has suggested that the foundation of such stress is low-grade systemic inflammation, as evidenced by increased interleukin 6 (IL-6) and C-reactive protein (CRP) levels. Soluble urokinase-type plasminogen activator receptor (suPAR) is a kidney disease risk factor and marker of chronic inflammation that integrates psycho-social stress and organ dysfunction. Caregivers of PD experience an extraordinary amount of stress and suPAR's role as prognostic marker has not yet been assessed in caregivers of PD. The aim of this study was to determine the relationship between suPAR levels and PD caregiver burden. Healthy volunteers who accompanied patients with parkinsonism (n = 35) donated blood samples, and complete blood counts (CBC), CRP, and suPAR levels were measured. Participants were then interviewed by telephone and stratified into primary and non-primary caregiver groups. Their caregiver burden was quantified through the Zarit Caregiver Burden Short Form (ZBI-12). The resultant data demonstrated higher plasma levels of suPAR and ZBI-12 scores for the primary caregiver group relative to the non-primary caregiver group (suPAR level: 3.73 vs. 2.72 ng/mL, p = 0.01; ZBI-12: 18.57 vs. 5.4, p < 0.0001; Table). The data also revealed a moderate positive correlation between suPAR and ZBI-12 scores. These findings not only demonstrate a correlation between elevated suPAR and caregiving burden in PD, but also further support and raise awareness for the overall psychosocial burden and stress experienced by those caregivers.

Communication and Language Skills of Autistic Spectrum Disorders in Children and Their Parents' Emotions.

BACKGROUND: Autism spectrum disorder (ASD) is a developmental disability, which is a biologically based neurodevelopmental disorder that affects a child's social interaction and communication skills. Core deficits are identified in two domains: social communication/interaction and restrictive, repetitive patterns of behavior. Children and youth with ASD have service needs in behavioral, educational, health, leisure, family support, and other areas. Autism is a set of heterogeneous neurodevelopmental conditions, characterized by inability to acquire social skills, repetitive behaviors and failure of speech and nonverbal communication development. OBJECTIVE: To examine frequency, correlation and predictivity of communication and language skills of autistic spectrum disorders (ASD) children and their parents' emotions. METHODS: The sample consisted of 80 participants who are parents of children with ASD. The study was performed using a questionnaire made out for this research. Three groups of variables were analyzed: parental emotions variables; child's communication variables, child's language variables. Statistical analysis was performed by SPSS, and included basic statistical parameters and multiple regression analysis. RESULTS: The most common ways of communicate for children with ASD are: Allowing to cuddle; Recognizes familiar faces; and Makes it known when he needs help or wants an item. The most common language forms of children ASD are: Following simple instructions; Understanding connected words/phrases; Pronouncing single words; and Looking at when called by name. Parents of children with ASD expressed the greatest agreement with the following statements: "My child is more demanding than most other children"; "It seems to me that my child is very sensitive and easily upset"; "My child can't do much of what he's expected to know to do", and "I often lack energy." CONCLUSION: Parents of children with ASD proved that their children have significant delays in communication and language. Developed communication and language skills of the child with ASD are valid predictors of parents' emotions/attitudes. Speech and language therapy work focused on developing the ASD child's communication and language skills can be expected to improve parents' emotions/attitudes.

Acute Maternal Stress Disrupts Infant Regulation of the Autonomic Nervous System and Behavior: A CASP Study.

Exposure to maternal stress is assumed to influence infant health and development across the lifespan. The autonomic nervous system (ANS) is especially sensitive to the effects of the early caregiving environment and linked to predictors of later mental health. Understanding how exposure to maternal stress adversely affects the developing ANS could inform prevention. However, there is no agreed upon definition of maternal stress making its study difficult. Here we use the Caretaker Acute Stress Paradigm (CASP) to study the effects of maternal stress in an experimentally controlled laboratory setting. The CASP has 5 episodes, a natural play, followed by a caretaker stressor (or control) condition, another play, a classic still face episode, followed by another play. A total of 104 4-months-old infants and their mothers were randomly assigned to either the caretaker-stress or caretaker-control condition. Changes in behavior, heart rate (HR), and respiratory sinus arrhythmia (RSA) before and after the introduction of the stressor (or control condition) were recorded and compared. Infants in the maternal stress condition showed significantly more behavioral distress [X 2 = (1, N = 104) = 4.662, p = 0.031]. Moreover, infants whose mothers were in the stress condition showed an significant increase in heart rate after the caretaker condition [F (1, 102) = 9.81, p = 0.002]. Finally we observed a trend to faster RSA recovery in infants of the control condition [F (1, 75) = 3.539, p = 0.064]. Results indicate that exposure to acute maternal stress affects infant regulation of the autonomic nervous system and behavior.

Adults' Acceptance of COVID-19 Vaccine for Children in Selected Lower- and Middle-Income Countries.

Since emergency approval of COVID-19 vaccines for children aged between 12 and 15 years old was recently obtained in the United States and Europe, we aimed to assess the willingness to vaccinate children with a COVID-19 vaccine in lower- and middle-income countries (LMICs). Therefore, we launched an online cross-sectional survey in several LMICs. Questions relating to socio-demographic information, knowledge of COVID-19, level of fear/worry of being infected with COVID-19, and willingness to vaccinate children with the COVID-19 vaccine at 50%, 75% and 95% effectiveness levels, were asked. Of the 6571 participants (mean age = 39 ± 14 years), 64.0%, 72.6%, and 92.9% were willing to vaccinate children at 50%, 75%, and 95% effectiveness levels, respectively. Respondents who were undergraduates, who were more worried/fearful about COVID-19, had higher knowledge scores regarding COVID-19, and a higher belief that COVID-19 vaccination is important to protect others, were more willing to accept COVID-19 vaccination of children. COVID-19 vaccination of children will limit the spread of the virus, especially in schools; it may decrease the need for school closures which has a negative effect on child development. Findings from this study are useful for health promotion strategies during COVID-19 vaccination implementation among children in LMICs.

Turnover events of animal caretakers and its impact on productivity in swine farms.

Attracting and retaining quality animal caretaking personnel is one of most pressing issues the US swine industry currently faces. On-farm employee turnover can be costly and have an impact on productivity. The primary objectives of this study were to describe the amount of animal caretaker turnover events that occurred in a single year in eleven swine farms, and to investigate associations between employee turnover events and two subsequent production parameters of interest: number of pigs weaned per sow (PWS) and pre-weaning mortality (PWM). A retrospective cohort study was conducted with eleven commercial farrow-to-wean swine farms belonging to two vertically integrated multi-site production systems within two swine production companies. Human resources and production data for the year of 2019 were obtained monthly from each farm. The primary predictor of interest was the occurrence of an employee turnover event, defined as 'voluntary' (employee decided to leave or quit) or 'involuntary' (employee was terminated by company decision). The primary outcomes of interest included the monthly average PWS and PWM. These associations were assessed with 1-, 2-, 3-, and 6-months between the turnover events and the outcome. Linear mixed effects models were fit in STATA 15, with system and farm included as random effects. To account for temporal and seasonal trends of production, season and the monthly production were included in the models. There were a total of 152 turnover events, with 4 and 148 turnover events in systems 1 and 2, respectively. The average turnover, calculated as a percent of total turnover among full time employee positions, was 92 % (SD = 62 %; Range = 8-217 %). Improved production efficiency in both monthly PWS (p = 0.01) and PWM (p = 0.02) was observed with the occurrence of an involuntary turnover event two months prior, after controlling for season, previous month production, farm, and system. For the PWS outcome, there was a significant interaction between an involuntary turnover event two months prior and monthly county-level unemployment rate (p = 0.02), indicative of the improved performance being most profound at the lowest levels of unemployment rate and diminishing at the highest levels. Turnover of animal caretaking personnel in farrow-to-wean farms was confirmed to be highly variable and high for the majority of farms in this study. Furthermore, animal caretaker turnover was associated with subsequent trends of production efficiency, warranting closer consideration of prioritizing managerial efforts in worker recruitment, training and retention.

Dairy Caretaker Perspectives on Performing Euthanasia as an Essential Component of Their Job.

The objectives of this study were to identify caretakers' perceptions and stressors related to performing on-farm euthanasia as well as potential ideas for intervention strategies to alleviate negative effects of performing euthanasia on caretaker well-being. Additionally, we aimed to determine how euthanasia methods, procedures, and training correlate with dairy caretakers' attitudes toward performing on-farm euthanasia and their job satisfaction and sense of well-being. Thirty-eight dairy caretakers (19 workers, 15 supervisors, 3 owners, 1 veterinarian) participated in focus groups or interviews conducted and recorded on five Northern Colorado dairies. Thematic analysis of focus group and interview transcripts revealed seven recurring themes. Variation in available training and euthanasia protocols among dairy farms was evident. There was a lack of awareness regarding available mental health resources and little communication between farm personnel about euthanasia-related stress. Training was correlated with caretaker knowledge about euthanasia procedures and the language used to refer to euthanasia. Human-animal bonds and empathy toward animals were evident in participants regardless of training, job position, or dairy experience. Interventions such as training programs, mental health resources, and other support systems should be tested for effectiveness in addressing euthanasia-related stressors, improving euthanasia decision-making and practice, and increasing animal wellbeing on dairy farms.
