The motivating effect of monetary over psychological incentives is stronger in WEIRD cultures.

Motivating effortful behaviour is a problem employers, governments and nonprofits face globally. However, most studies on motivation are done in Western, educated, industrialized, rich and democratic (WEIRD) cultures. We compared how hard people in six countries worked in response to monetary incentives versus psychological motivators, such as competing with or helping others. The advantage money had over psychological interventions was larger in the United States and the United Kingdom than in China, India, Mexico and South Africa (N = 8,133). In our last study, we randomly assigned cultural frames through language in bilingual Facebook users in India (N = 2,065). Money increased effort over a psychological treatment by 27% in Hindi and 52% in English. These findings contradict the standard economic intuition that people from poorer countries should be more driven by money. Instead, they suggest that the market mentality of exchanging time and effort for material benefits is most prominent in WEIRD cultures.

Trends and factors associated with HIV testing among women aged 15-49 years in Belize: an analysis using the Multiple Indicator Cluster Survey 2006, 2011, and 2015-2016.

BACKGROUND: Belize has one of the highest human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome prevalence rates in Central America, with women of reproductive age being particularly vulnerable to HIV. Therefore, this study examined the factors associated with HIV testing among women of reproductive age in Belize and trends in HIV testing in 2006, 2011, and 2015-2016. METHODS: Cross-sectional data were analyzed using three Belize Multiple Indicator Cluster Surveys. The number of participants were 1,675, 4,096, and 4,699 women aged 15-49 years in 2006, 2011, and 2015-2016, respectively. We used variance-weighted least-squares regression to estimate annual changes. Multivariate logistic regression analysis was performed to evaluate the associated factors. Analyses were conducted using Stata version 15, and weights were applied for generalization to the population. RESULTS: HIV testing rates increased from 47.7% in 2006 to 66.5% in 2015, with an average annual change of 0.082 (95% confidence interval: 0.07-0.09). Logistic regression models showed that women aged 15-24 years were less likely to have been tested for HIV compared to women aged 25-34 years. Women from the Mayan ethnic group were less likely to have been tested than those from other ethnic groups. Compared to women who spoke Spanish, those who spoke English/Creole were more likely to have been tested for HIV; additionally, those who spoke minority languages were less likely to have been tested. Being married and having given birth were associated with increased odds of HIV testing. Living in rural areas and households with the poorest wealth indices were associated with decreased odds of being tested for HIV. Women with good HIV knowledge and accepting attitudes towards people living with HIV were more likely to be tested. CONCLUSIONS: From 2006 to 2015, HIV testing in women of reproductive age showed an increasing trend in Belize. We recommend interventions to expand HIV testing for women of reproductive age in Belize, particularly those aged 15-24 years, speaking minority languages, living in rural areas, and having a low socioeconomic status.

Factors associated with postpartum depression symptoms among postpartum women in five countries during the COVID-19 pandemic: an online cross-sectional study.

BACKGROUND: This study aimed to examine factors associated with postpartum depression (PPD) symptoms during the COVID-19 pandemic among postpartum women in five countries, a subject that has not been investigated thus far. METHODS: A multi-country, cross-sectional, online survey was conducted with a convenience sample of 3,523 postpartum women in Brazil, South Korea, Taiwan, Thailand, and the United Kingdom, from July to November 2021. Sociodemographic and obstetric data, food insecurity, COVID-19 positive status, COVID-19 vaccination, infant feeding, breastfeeding belief score, and social support were investigated. PPD and social support were measured using the Edinburgh Postnatal Depression Scale and Maternal Social Support Scale, respectively. Descriptive statistics, chi-squared tests, and t-tests were used to identify associations with PPD symptoms. A binary logistic regression model was used to identify explanatory factors associated with PPD and adjusted odds ratios (OR) and 95% confidence intervals (CIs) were calculated. RESULTS: Women in Taiwan (AOR = 0.5; 95%CI 0.34, 0.73) and Thailand (AOR = 0.68; 95%CI 0.46, 0.99) had a lower risk of PPD symptoms than those in Brazil. In addition, women with planned pregnancies had a lower risk of PPD (AOR = 0.74; 95%CI 0.60, 0.91). Younger women (AOR = 1.62; 95%CI 1.05, 2.51), health problems during pregnancy, delivery, or postpartum (AOR = 1.71; 95%CI 1.42, 2.06), and no change or worse food insecurity during COVID-19 (AOR = 1.66; 95%CI 1.21, 1.27 for no change and AOR = 1.68; 95%CI 1.27, 1.23, respectively) presented a higher likelihood of having PPD. Feeding babies with expressed human milk (AOR = 1.25; 95%CI 1.03, 1.50) and/or complementary food (AOR = 1.51; 95%CI 1.17, 1.94) were associated with PPD symptoms. Women who received low (AOR = 7.74; 95%CI 5.43, 11.03) or medium support (AOR = 3.25; 95%CI 2.71, 3.88) had higher likelihoods of PPD. CONCLUSION: PPD symptoms during the pandemic were high in young women, particularly Brazilian women, with health problems in the puerperal pregnancy cycle who fed their babies expressed breast milk and/or complementary food. Low social support also impacted PPD symptoms. This study highlights the need for the professional screening for PPD and provision of virtual or personal support.

Bioinformatic analysis of single-cell RNA sequencing dataset dissects cellular heterogeneity of triple-negative breast cancer in transcriptional profile, splicing event and crosstalk network.

BACKGROUND: Triple-negative breast cancer (TNBC) is a subtype of breast cancer with high tumoral heterogeneity, while the detailed regulatory network is not well known. METHODS: Via single-cell RNA-sequencing (scRNA-seq) data analysis, we comprehensively investigated the transcriptional profile of different subtypes of TNBC epithelial cells with gene regulatory network (GRN) and alternative splicing (AS) event analysis, as well as the crosstalk between epithelial and non-epithelial cells. RESULTS: Of note, we found that luminal progenitor subtype exhibited the most complex GRN and splicing events. Besides, hnRNPs negatively regulates AS events in luminal progenitor subtype. In addition, we explored the cellular crosstalk among endothelial cells, stromal cells and immune cells in TNBC and discovered that NOTCH4 was a key receptor and prognostic marker in endothelial cells, which provide potential biomarker and target for TNBC intervention. CONCLUSIONS: In summary, our study elaborates on the cellular heterogeneity of TNBC, revealing that NOTCH4 in endothelial cells was critical for TNBC intervention. This in-depth understanding of epithelial cell and non-epithelial cell network would provide theoretical basis for the development of new drugs targeting this sophisticated network in TNBC.

Parasitic helminth infections in humans modulate Trefoil Factor levels in a manner dependent on the species of parasite and age of the host.

Helminth infections, including hookworms and Schistosomes, can cause severe disability and death. Infection management and control would benefit from identification of biomarkers for early detection and prognosis. While animal models suggest that Trefoil Factor Family proteins (TFF2 and TFF3) and interleukin-33 (IL-33) -driven type 2 immune responses are critical mediators of tissue repair and worm clearance in the context of hookworm infection, very little is known about how they are modulated in the context of human helminth infection. We measured TFF2, TFF3, and IL-33 levels in serum from patients in Brazil infected with Hookworm and/or Schistosomes, and compared them to endemic and non-endemic controls. TFF2 was specifically elevated by Hookworm infection in females, not Schistosoma or co-infection. This elevation was correlated with age, but not worm burden. TFF3 was elevated by Schistosoma infection and found to be generally higher in females. IL-33 was not significantly altered by infection. To determine if this might apply more broadly to other species or regions, we measured TFFs and cytokine levels (IFNγ, TNFα, IL-33, IL-13, IL-1ß, IL-17A, IL-22, and IL-10) in both the serum and urine of Nigerian school children infected with S. haematobium. We found that serum levels of TFF2 and 3 were reduced by infection, likely in an age dependent manner. In the serum, only IL-10 and IL-13 were significantly increased, while in urine IFN-γ, TNF-α, IL-13, IL-1ß, IL-22, and IL-10 were significantly increased in by infection. Taken together, these data support a role for TFF proteins in human helminth infection.

Nurse Burnout Revisited: A Comparison of Computational Methods.

BACKGROUND AND PURPOSE: To examine computational measures of job-related burnout to determine the best computation to estimate job satisfaction and intent to leave in Brazilian nursing professionals. METHODS: Maslach Burnout Inventory-Human Services Survey (MBI-HSS) was used assess burnout in 452 hospital-based nursing professionals. Adjusted logistic regression models were fit using different computations of burnout to estimate outcomes of interest. RESULTS: Total mean score of burnout subscales was the best estimate of job satisfaction (Cox-Snell R2 = 0.312; Nagelkerke R2 = 0.450) and intent to leave (Cox-Snell R2 = 0.156; Nagelkerke R2 = 0.300), as was high emotional exhaustion (Cox-Snell R2 = 0.219; Nagelkerke R2 = 0.316). CONCLUSION: We have provided evidence that different computations of data from the Portuguese (Brazil) MBI-HSS can be used in to estimate the effect of job-related burnout on nurse outcomes.

Solitary chemosensory cells are a primary epithelial source of IL-25 in patients with chronic rhinosinusitis with nasal polyps.

BACKGROUND: IL-25 can function as an early signal for the respiratory type 2 response characteristic of allergic asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). In the mouse gut, tuft cells are the epithelial source of IL-25. However, the source of human airway epithelial IL-25 has remained elusive. OBJECTIVE: In this study we sought to determine whether the solitary chemosensory cell (SCC) is the predominant source of IL-25 in the sinonasal epithelium. METHOD: Flow cytometry and immunofluorescence for SCCs and IL-25 were used to interrogate polyp and turbinate tissue from patients with CRSwNP. Mucus was collected during acute inflammatory exacerbations from patients with CRSwNP or chronic rhinosinusitis without nasal polyps and IL-25 levels determined by using ELISA. Lastly, sinonasal epithelial cultures derived from polyp and turbinate tissue were stimulated with IL-13 and analyzed for SCC proliferation and IL-25 production. RESULTS: This study demonstrates that a discrete cell type, likely an SCC, characterized by expression of the taste-associated G protein gustducin and the intestinal tuft cell marker doublecortin-like kinase 1, is the predominant source of IL-25 in the human upper airway. Additionally, we show that patients with CRSwNP have increased numbers of SCCs in nasal polyp tissue and that in vitro IL-13 exposure both increased proliferation and induced apical secretion of IL-25 into the mucosal layer. CONCLUSIONS: Inflammatory sinus polyps but not adjacent turbinate tissue show expansion of the SCC population, which is the source of epithelial IL-25.

Food Insecurity Is Associated with Subsequent Cognitive Decline in the Boston Puerto Rican Health Study.

BACKGROUND: Living with hunger and fear of not having enough food is a growing worldwide concern. In our previous cross-sectional study, we found that food insecurity was associated with poor cognitive function, but the direction of this relation remains unclear. OBJECTIVE: We investigated whether food insecurity is associated with subsequent cognitive decline. METHODS: This was a longitudinal study of 597 participants aged 40-75 y from the Boston Puerto Rican Health Study cohort, with a Mini-Mental State Examination score of ≥24 at baseline. Food security was assessed at baseline with the US Household Food Security Scale. Participants completed cognitive batteries, which included 7 cognitive tests, twice-at baseline and again at a 2-y follow-up. The primary outcome was the change in global cognitive function over 2 y. Multiple linear regression was used to obtain adjusted mean differences and 95% CIs in cognitive decline across baseline food security status. RESULTS: Food insecurity at baseline was associated with a 2-y decline in global cognitive function (P-trend = 0.03) after adjusting for relevant potential confounders, including age, sex, baseline cognitive score, body mass index, education, poverty, acculturation score, depression score, smoking status, use of alcohol, physical activity score, presence of diabetes and hypertension, apolipoprotein E status, plasma homocysteine, healthy eating index, and time between baseline and follow-up measures. Compared with the food-secure group, the decline in the very low food security group was greater [mean difference: -0.26 (95% CI: -0.41, -0.10)]. Baseline food insecurity was significantly associated with a faster decline in executive function (P-trend = 0.02) but not memory function (P-trend = 0.66). CONCLUSIONS: Food insecurity was associated with faster cognitive decline in this cohort of Puerto Rican adults. Our study emphasizes the importance of developing interventions for food insecurity that take into account the impact of food insecurity on cognition.

Saturnispora serradocipensis sp. nov. and Saturnispora gosingensis sp. nov., two ascomycetous yeasts from ephemeral habitats.

Two novel ascomycetous yeast species, Saturnispora serradocipensis and Saturnispora gosingensis, were isolated from leaf detritus in a tropical stream of Southeastern Brazil and a mushroom collected in Taiwan, respectively. Analysis of the D1/D2 domains of the large-subunit of the rRNA gene of these strains showed that these species are related to Saturnispora hagleri, their closest relative. Saturnispora serradocipensis and S. gosingensis differed from S. hagleri, respectively, by seven nucleotide substitutions and two indels and three nucleotide substitutions and three indels in D1/D2 rRNA sequences. The two new species differ from each another by four nucleotide substitutions and one indel in D1/D2 rRNA sequences. However, the ITS sequences of S. serradocipensis, S. gosingensis and S. hagleri were quite divergent, showing that they are genetically separate species. The type strain of S. serradocipensis is UFMG-DC-198(T) (=CBS 11756(T) = NRRL Y-48717(T)), and of S. gosingensis GA4M05(T) is (CBS 11755(T) = NRRL Y-48718(T)).

Factors associated with utilization of traditional Chinese medicine by white collar foreign workers living in Taiwan.

BACKGROUND: Traditional Chinese medicine (TCM) has remained an integral part of Chinese culture and society for thousands of years. In Taiwan TCM is a recognized element of its National Health Insurance Scheme. However, there is no knowledge about how TCM is accessed by foreign workers from a non-Asian cultural background. The objectives of this study were to investigate the prevalence and patterns of TCM use among non-Asian white-collar workers living in Taiwan, and examine factors likely to influence their use of TCM. METHODS: This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study. RESULTS: The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31-40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan. CONCLUSION: Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.

Stigmatization of patients with HIV/AIDS among doctors and nurses in Belize.

This study, conducted from August to September 2007, utilized a population-based survey to investigate stigmatizing attitudes and acts of discrimination against HIV/AIDS patients among doctors and nurses working in public hospitals in Belize. A total of 230 subjects (81.0%) completed the survey. The mean age was 36.8 years; 75% were women; 61% were nurses; 74% were Belizean. Stigmatization was greatest for "attitudes of blame/judgment"; disclosing a patient's HIV/AIDS status to colleagues was the most frequent act of discrimination (29%). Formal HIV/AIDS training was significantly associated with less stigmatization for "attitudes towards imposed measures" (p < .01); "attitudes of blame/judgment" (p < 0.05); and testing without consent (p < 0.05). Doctors showed more stigmatization in "attitudes towards imposed measures," conducted HIV tests without consent and disclosed patient status to colleagues more frequently than nurses (p < 0.05) while nurses gave differential care to patients based on HIV status more frequently (p < 0.01) than doctors. Female and religious health care workers (HCWs) were more stigmatizing in their "attitudes of blame/judgment" than male and nonreligious HCWs (p < 0.05). Cuban HCWs were more stigmatizing in their "attitudes toward imposed measures" and were less comfortable dealing with HIV/AIDS patients than their Belizean counterparts (p < 0.01). Older age was associated with less frequent disclosure of patients' HIV status (p < 0.05). HIV/AIDS training that incorporates stigma reduction strategies tailored to the target groups identified is needed. Additionally, we recommend that the effectiveness of national HIV/AIDS policies be investigated.
