Salt and Aldosterone – Reciprocal and Combined Effects in Preclinical Models and Humans

Abstract Primary aldosteronism is an endocrine disorder caused by excessive production of aldosterone by the adrenal glands, and is recognized as the most important cause of endocrine hypertension. With specific therapy, this type of hypertension is potentially curable. In the general population, high salt intake increases the risk for cardiovascular diseases like stroke. In populations with aldosterone excess, observational and experimental data suggest that aldosterone-induced organ damage requires a combination of high dietary salt intake and high plasma aldosterone, i.e., plasma aldosterone levels inappropriately high for salt status. Therefore, understanding the relationship between plasma aldosterone levels and dietary salt intake and the nature of their combined effects is crucial for developing effective prevention and treatment strategies. In this review, we present an update on findings about primary aldosteronism and salt intake and the underlying mechanisms governing their interaction.
CD40L modulates CD4+ T‐cell activation through receptor for activated C kinase 1

Inhibition of the co‐stimulatory ligand CD40L has shown beneficial effects in many experimental models of autoimmune disease and inflammation. Here, we show that CD40L deficiency in T cells in mice causes a reduction of CD4+ T‐cell activation and specifically a strong reduction in IFN‐γ‐producing Th1 cells. In vitro, we could not reproduce this antigen presenting cell‐dependent effects, but found that T‐cell CD40L affects cell death and proliferation. We identified receptor of activated C kinase, the canonical PKC binding partner and known to drive proliferation and apoptosis, as a mediator of CD40L reverse signaling. Furthermore, we found that CD40L clustering stabilizes IFN‐γ mediated Th1 polarization through STAT1, a known binding partner of receptor of activated C kinase. Together this highlights the importance of both CD40L forward and reverse signaling.
Modeling users’ satisfaction and visit intention using AI-based chatbots

AI-based chatbots are an emerging technology disrupting the tourism industry. Although chatbots have received increasing attention, there is little evidence of their impact on tourists’ decisions to visit a destination. This study evaluates the key attributes of chatbots and their effects on user satisfaction and visit intention. We use structural equation modeling with covariance procedures to test the proposed model and its hypotheses. The results showed that informativeness, empathy, and interactivity are critical attributes for satisfaction, which drive tourists’ intention to visit a destination.
Determination of process contaminants 2- and 3-MCPD esters and glycidyl esters in palm-based glycerol by indirect analysis using GC-MS

Abstract Esters of 2- and 3-monochloropropanediol (2-MCPDE, 3-MCPDE) and glycidol (GE) are regarded as process contaminants that are found in refined vegetable oils and oil-based foods. Since glycerol is produced during fat splitting, saponification and biodiesel production, it is important to have methods for determining contaminants that might be formed during these processes. Due to the use of glycerol as a food additive, data on the presence of compounds of toxicological concern, including 3-MCPD, are of interest. This study focuses on modifying the indirect analysis of 2-MCPDE, 3-MCPDE and GE using GC-MS based on the AOCS Official Method Cd 29a-13, validating the modified method, and quantifying 2-MCPDE, 3-MCPDE and GE in glycerol. The AOCS Cd 29a-13 method was modified at the initial stage of sample preparation in which the targeted esters were extracted from glycerol by vortex-assisted extraction before sample analysis. This modification was performed based on the polarity of all compounds involved. The calibration functions for all analytes were fitted to linear regression with R 2 above 0.99. Limits of detection (LOD) 0.02, 0.01 and 0.02 mg kg−1 were obtained for 2-MCPDE, 3-MCPDE and GE, respectively. Spiked glycerol with 3-MCPDE and 2-MCPDE (0.25, 0.51 and 1.01 mg kg−1) and GE (0.58, 1.16 and 2.32 mg kg−1) were used for recovery and precision measurements. Recoveries of 100-108%, 101-103%, and 93-99% were obtained for 2-MCPDE, 3-MCPDE and GE, respectively. Acceptable precision levels with relative standard deviations ranged from 3.3% to 8.3% were obtained for repeatability and intermediate precision. The validated method was successfully applied for the analysis of the target compounds in refined glycerol from commercial plants, which showed that 2-MCPDE, 3-MCPDE and GE levels in the analysed samples were below the detection limit.
Osteoprotective Role of the Mir338 Cluster Ablation during Periodontitis

Periodontitis is a chronic inflammatory disease that compromises the integrity of the supporting tissues of the teeth and leads to the loss of the alveolar bone. The Mir338 cluster has been proven to be a potential target for the treatment of osteoporosis and is also enriched in gingival tissues with periodontitis; however, its role in periodontitis remains unknown. Here, we aimed to use periodontitis as a model to expand our understanding of the Mir338 cluster in osteoimmunology and propose a new target to protect against bone loss during periodontitis progression. Significant enrichment of the Mir338 cluster was validated in gingival tissues from patients with chronic periodontitis and a ligature-induced periodontitis mouse model. In vivo, attenuation of alveolar bone loss after 7 d of ligature was observed in the Mir338 cluster knockout (KO) mice. Interestingly, immunofluorescence and RNA sequencing showed that ablation of the Mir338 cluster reduced osteoclast formation and elevated the inflammatory response, with enrichment of IFN-γ and JAK-STAT signaling pathways. Ablation of the Mir338 cluster also skewed macrophages toward the M1 phenotype and inhibited osteoclastogenesis via Stat1 in vitro and in vivo. Furthermore, the local administration of miR-338-3p antagomir prevented alveolar bone loss from periodontitis. In conclusion, the Mir338 cluster balanced M1 macrophage polarization and osteoclastogenesis and could serve as a novel therapeutic target against periodontitis-related alveolar bone loss.
Effects of disability type, prior contact, and school setting on attitudes toward peers with disabilities among Saudi female students aged 7 to 12 years

Background Inclusive educational practices enhance engagement among students with disabilities in school settings. This study aimed to investigate: (i) the general attitudes of non-disabled female Saudi Arabian students toward their peers with disabilities, with a particular focus on the general attitudes towards those with hearing disabilities (HD), intellectual disabilities (ID), and behavioral problems (BP), and (ii) the relationships between three selected student-related characteristics (type of school, in-school contact with peers with disabilities, and out-of-school contact with peers with disabilities). Method Using a sample of 678 participants aged 7–12 years old, we tested the impact of personal and contextual factors (age, type of peer disability, type of school, in-school interaction with peers with disabilities, and out-of-school interaction with peers with disabilities on the attitudes of non-disabled Saudi Arabian elementary school students using ANCOVA linear regression analysis. Results Regardless of the type of disability, the participants reported having positive attitudes toward peers with disabilities. The type of disability, school, and previous interactions all had a significant effect on fostering positive attitudes toward peers with disabilities, specifically, those with HD, ID, and BP. The participants had less positive attitudes towards their peers with BP compared to their attitudes towards peers students with HD or ID which were more positive and had a larger effect size. The findings also demonstrated that the participants’ attitudes toward their peers with HD or ID were influenced by their previous experience of interacting with people with disabilities as well as the type of school they attended. Participants from Saudi ARAMCO (SA) schools had more positive attitudes toward peers with disabilities compared to those from public schools, and participants from non-inclusive schools had more positive attitudes toward peers with disabilities compared to those from inclusive schools. Participants from non-inclusive schools had much more positive attitudes toward peers with disabilities than those from inclusive schools; participants who had previous out-of-school interactions with people with disabilities had significantly more positive attitudes toward peers with disabilities than those who had no previous out-of-school interactions with people with disabilities. Participants from SA schools had the most negative attitudes toward peers with BP, regardless of age. Conclusions The findings imply that being taught in an inclusive educational setting in Saudi Arabia does not inevitably encourage non-disabled students to adopt more positive attitudes toward peers with disabilities. Therefore, with the support of their school principals, Saudi Arabian teachers working in inclusive educational settings should be encouraged to develop and implement initiatives to adopt an inclusive strategy based on group projects bringing together students with and without disabilities.
Do pregnant African women exercise? A meta-analysis

Introduction Antenatal exercise can reduce gestational weight gain, backache; pregnancy induced medical disorders, caesarean section rates, and improves pregnancy outcomes. American College of Obstetrics and Gynecology (ACOG) recommends prenatal exercise, which is associated with minimal risk and has been shown to be beneficial for pregnancy outcomes, although some exercise routines may need to be modified. Consequently, this meta-analysis is intended to verify the pooled practice of antenatal exercise in Africa using available primary articles. Methods Genuine search of the research articles was done via PubMed, Scopes, Cochrane library, the Web of Science; free Google databases search engines, Google Scholar, and Science Direct databases. Published and unpublished articles were searched and screened for inclusion in the final analysis and Studies without sound methodologies, and review and meta-analysis were not included in this analysis. The Newcastle–Ottawa scale was used to assess the risk of bias. If heterogeneity exceeded 40%, the random effect method was used; otherwise, the fixed-effect method was used. Meta-analysis was conducted using STATA version 14.0 software. Publication bias was checked by funnel plot and Egger test. Results This review analyzed data from 2880 women on antenatal care contact from different primary studies. The overall pooled effect estimate of antenatal exercise in Africa was 34.50(32.63–36.37). In the subgroup analysis for pooled antenatal exercise practice by country, it was 34.24 (31.41–37.08) in Ethiopia and 37.64(34.63–40.65) in Nigeria. Conclusion The overall pooled effect estimate of antenatal exercise in Africa was low compared to other continent. As it was recommended by ACOG antenatal exercise to every patient in the absence of contraindications, it should be encouraged by professionals providing antenatal care service.
Canadians’ trust in government in a time of crisis: Does it matter?

The ability of governments and nations to handle crises and protect the lives of citizens is heavily dependent on the public’s trust in their governments and related social institutions. The aim of the present research was to understand public trust in government during a time of crisis, drawing on interview data (N = 56) collected during the COVID-19 pandemic (2021). In addition to the general public (n = 11), participants were sampled to obtain diversity as it relates to identifying as First Nations, Métis, and Inuit (n = 7), LGBT2SQ+ (n = 5), low-income (n = 8), Black Canadians (n = 7), young adult (n = 8), and newcomers to Canada (n = 10). Data were coded in consideration of social theories of trust, and specifically the nature of trust between individuals and institutions working with government in pandemic management. Canadians’ trust in government was shaped by perceptions of pandemic communication, as well as decision-making and implementation of countermeasures. Data suggest that although participants did not trust government, they were accepting of measures and messages as presented through government channels, pointing to the importance of (re)building trust in government. Perhaps more importantly however, data indicate that resources should be invested in monitoring and evaluating public perception of individuals and institutions generating the evidence-base used to guide government communication and decision-making to ensure trust is maintained. Theoretically, our work adds to our understanding of the nature of trust as it relates to the association between interpersonal and institutional trust, and also the nature of trust across institutions.
Self-reported abortion experiences in Ethiopia and Uganda, new evidence from cross-sectional community-based surveys

Unsafe abortion is a major contributor to maternal morbidity and mortality. To gain insight into the ways in which abortion restrictions and stigma may shape reproductive health outcomes, we present self-reported data on abortions in Ethiopia and Uganda and compare these findings across the two varying legal contexts. W investigate differences in sociodemographic characteristics by whether or not a woman self-reported an abortion, and we describe the characteristics of women’s most recent self-reported abortion. In Ethiopia only, we classified abortions as being either safe, less safe, or least safe. Finally, we estimate minimum one-year induced abortion incidence rates using the Network Scale-Up Method (NSUM). We find that women who self-reported abortions were more commonly older, formerly married, or had any children compared to women who did not report an abortion. While three-quarters of women in both settings accessed their abortion in a health facility, women in Ethiopia more commonly used public facilities as compared to in Uganda (23.0% vs 12.6%). In Ethiopia, 62.4% of self-reported abortions were classified as safe, and treated complications were more commonly reported among least and less safe abortions compared to safe abortions (21.4% and 23.1% vs. 12.4%, respectively). Self-reported postabortion complications were more common in Uganda (37.2% vs 16.0%). The NSUM estimate for the minimum one-year abortion incidence rate was 4.7 per 1000 in Ethiopia (95% CI 3.9–5.6) and 19.4 per 1000 in Uganda (95% C 16.2–22.8). The frequency of abortions and low levels of contraception use at the time women became pregnant suggest a need for increased investments in family planning services in both settings. Further, it is likely that the broadly accessible nature of abortion in Ethiopia has made abortions safer and less likely to result in complications in Ethiopia as compared to Uganda.
Synthesis of water-stable and highly luminescent graphite quantum dots

Highly stable and environmentally friendly nitrogen-doped graphite quantum dots consisting of ∼12 layers of graphene, average diameter of ∼7.3 nm, prepared by atmospheric pressure microplasma are reported to have blue emission due to surface states created by nitrogen doping (9 atomic%) and reaction with oxygen. The low-temperature synthesis method requires simple precursors in water, with no annealing or filtration, producing crystalline disc-shaped quantum dots with ∼68% photoluminescence emission quantum yield at 420 nm excitation and that have shown stability for more than one month after the synthesis. The nitrogen doping in the quantum dots mainly occurs in graphitic core as substituted type of doping (63–67 atomic%) and the amount of doping is sufficient to create emissive states without impacting the core structure. The optical and chemical properties do not undergo serious retardation even with re-dispersion suggesting easy applicability for cellular imaging or optoelectronics.
Cultivating a Science, Technology, Engineering and Mathematics (STEM) community for two-year college student success and persistence

Undergraduate students studying Science, Technology, Engineering and Mathematics (STEM) often fail to persist in critical “gateway” courses, resulting in students leaving the STEM pathway. Community college students leave STEM pathways at higher rates than students at universities. Implementation of a program designed to engage community college STEM students and faculty in a community of support was associated with increased persistence in STEM gateway courses and associate degree completion. Program elements included support staff, a STEM study room with peer tutors, faculty advisors, and transfer assistance. Over seven years, 415 students joined this opt-in support program. The majority of students in this program were economically disadvantaged and many were nontraditional college students. Using institutional data we tested the hypothesis that participation in this program was associated with increased student success and persistence in STEM courses and at the college. The mean GPA for students in the program in the ten courses with the highest STEM enrollments was higher (2.89) than that for other students (2.76). Quarter-to-quarter persistence was 87% for program students compared to 67% for non-program students in a matched student population. In STEM gateway courses, program students had between 1.2x to 3.5x greater likelihood than non-program students of progressing to precalculus-2 controlling for first-attempt GPA in precalculus-1. Similar persistence patterns were observed for other gateway STEM courses. Observed persistence for students in the program was higher than comparable groups of students, including persistence for those who experienced early failure in STEM courses. These data suggest students should be supported through early failure to enable persistence in critical STEM sequences, especially in gateway Math and Chemistry courses.
Sexually transmitted infection knowledge among men who have sex with men in Nairobi, Kenya

Background High rates of sexually transmitted infections (STIs) among men who have sex with men (MSM) have been reported, but there is little research on their STI knowledge. Our study sought to determine participants’ characteristics that contribute to either high or low STI knowledge among MSM in Nairobi, Kenya. Methods We mobilized MSM aged ≥18 years from Nairobi into a cross-sectional study. To determine their understanding of STIs, a pre-tested structured questionnaire was administered. Knowledge score was generated by summing up the number of responses answered correctly by a participant. We dichotomized scores as “low” and “high”, by splitting the group at <12 and ≥12 which was the mean. Results A total of 404 participants were interviewed between March and August 2020. The mean age was 25.2 (SD = 6.4) years. Majority were single (80.4%) and Christians (84.2%). All participants had some formal education ranging from primary to tertiary; the majority (92.3%) had secondary education or more. Most (64.0%) were employed and their monthly income ranged from <50->150 USD. Almost all (98.5%) were Kenyans. Of the 404 (90.6%) self-identified as male and (47.5%) reported to be exclusively top partners. Many (39.9%) reported being versatile, while those reporting to be bottom partners were, (12.6%). The last 12 months, (55.4%) of the participants reported having sex with men only and (88.6%) reported to have had multiple sexual partners. Participants scored an average of 12.2, SD 4.5. Multivariable backward elimination logistic regression revealed that participants who had tertiary education (aOR = 0.50, 95% CI 0.32–0.77), a higher income (aOR = 0.40, 95% CI 0.22–0.75) and were engaging in vaginal sex (aOR = 1.86, 95% CI 1.25–2.78) predicted significantly higher odds of high knowledge in the final multivariable model. Conclusion Participant’s knowledge level regarding STIs was low. We recommend health care workers to continue educating patients about STIs.
Mortality and prognostic factors for spontaneous pneumothorax in older adults

Spontaneous pneumothorax occurs predominantly in young males and older adults, often as a secondary condition, and can be refractory and fatal. This study aimed to investigate the mortality and prognostic factors for pneumothorax in older patients. We retrospectively cohort studied patients with pneumothorax aged ≥65 years who visited our department from October 2012 to January 2019. Data on sex, age, medical history, smoking history, underlying lung disease, treatment, and prognosis were extracted from medical records. Cox proportional hazards regression analysis was used to investigate pneumothorax mortality and prognostic factors. In total, 239 patients were included. Among them, 36 (15%) died during hospitalization. Respiratory disease was the direct cause of death in 30 patients (83.3%), and 211 (88.3%) patients had underlying lung disease. The incidence of pneumonia in our hospital was 22.6% (54 cases). On admission, the mortality rate was 33% (18/54) in patients with concomitant pneumonia; univariate analysis showed significant differences in the Charlson Comorbidity Index (CCI), activities of daily living (ADL), and concomitant pneumonia. In the Cox proportional hazards analysis of ADL (p = 0.09), CCI (p = 0.05), and concomitant pneumonia on admission (p = 0.02), concomitant pneumonia on admission was found to be an independent predictor of in-hospital mortality. This study suggests that concomitant pneumonia at admission may be a mortality risk factor for pneumothorax.
Review of intervention products for use in the prevention and control of anemia

Anemia remains a major public health problem, especially in low‐ and middle‐income countries. The World Health Organization recommends several interventions to prevent and manage anemia in vulnerable population groups, including young children, menstruating adolescent girls and women, and pregnant and postpartum women. Daily iron supplementation reduces the risk of anemia in infants, children, and pregnant women, and intermittent iron supplementation reduces anemia risk in menstruating girls and women. Micronutrient powders reduce the risk of anemia in children. Fortifying wheat flour with iron reduces the risk of anemia in the overall population, whereas the effect of fortifying maize flour and rice is still uncertain. Regarding non‐nutrition‐related interventions, malaria treatment and deworming have been reported to decrease anemia prevalence. Promising interventions to prevent anemia include vitamin A supplementation, multiple micronutrient supplementation for pregnant women, small‐quantity lipid‐based supplements, and fortification of salt with iodine and iron. Future research could address the efficacy and safety of different iron supplementation formulations, identify the most bioavailable form of iron for fortification, examine adherence to supplementation regimens and fortification standards, and investigate the effectiveness of integrating micronutrient, helminth, and malaria control programs.
