Self-efficacy was identified as mediator between treatment condition and behavioral changes of brushing and flossing. Combining theories of HBM and SCT is a promising avenue for efficacy in oral health behaviors. The effects were mediated through cognitive variables, which provided guidance for both theory and health intervention development.Although convergence is often recognized as a ubiquitous feature across the Tree of Life, whether the underlying traits also exhibit similar evolutionary pathways towards convergent forms puzzles biologists. In carnivoran mammals, "elongate," "slender," and "long" are often used to describe and even to categorize mustelids (martens, polecats, and weasels), herpestids (mongooses), viverrids (civets and genets), and other carnivorans together. But just how similar these carnivorans are and whether there is convergence in the morphological component that contribute to elongation has never been assessed. Here, I found that these qualitatively-described elongate carnivorans exhibited incomplete convergence towards elongate bodies compared to other terrestrial carnivorans. In contrast, the morphological components underlying body shape variation do not exhibit convergence despite evidence that these components are more elongate in elongate carnivorans compared to non-elongate carnivorans. Furthermore, these components also exhibited shorter but different phylogenetic half-lives towards more elongate adaptive peaks, indicating that different selective pressures can create multiple pathways to elongation. Incorporating the fossil record will facilitate further investigation of whether body elongation evolved adaptively or if it is simply a retained ancestral trait.
Leprosy is a chronic infectious disease caused by Mycobacterium leprae, which continues to be endemic in tropical countries, making it necessary to implement strategies for its elimination. The objective of the current article was to detect M. leprae infection and associated factors through serological and epidemiological evaluation in family clusters of leprosy patients.

Mycobacterium leprae infection was determined in 50 family clusters of leprosy patients from the departments of Bolívar, Atlántico, Santander, Boyacá, Chocó and Antioquia through the detection of antibodies (protein A, IgM, IgG) against anti-natural octyl disacharide-leprosy IDRI diagnostic (NDO-LID).

Higher seroconversion and elevated titers of these antibodies against NDO-LID were observed in the population of Chocó and Atlántico (p<0.05). Additionally, a higher frequency of infection was observed in large family groups that consumed armadillo meat and belonged to a low socioeconomic stratum (p<0.05). Multivariate analysis established that the main associated factors for a family cluster experiencing this infection were belonging to a vulnerable economic stratum and a large family group.

This study found that the set of social and demographic variables (i.e. armadillo consumption, geographic area, low socioeconomic status and belonging to a large family cluster) are related to the promotion of seropositivity in family clusters.

In the green alga Chlamydomonas reinhardtii, two distinct photosynthetic acclimation states have been described under CO2-limiting conditions (low-CO2 [LC] and very low-CO2 [VLC]). LC-inducible protein B (LCIB), structurally characterized as carbonic anhydrase, localizes in the chloroplast stroma under CO2-supplied and LC conditions. In VLC conditions, it migrates to aggregate around the pyrenoid, where the CO2-fixing enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase is enriched. Although the physiological importance of LCIB localization changes in the chloroplast has been shown, factors necessary for the localization changes remain uncertain. Here, we examined the effect of pH, light availability, photosynthetic electron flow, and protein synthesis on the localization changes, along with measuring Ci concentrations. LCIB dispersed or localized in the basal region of the chloroplast stroma at 8.3-15 µM CO2, whereas LCIB migrated toward the pyrenoid at 6.5 µM CO2. Furthermore, LCIB relocated toward the pyrenoid at 2.6-3.4 µM CO2, even in cells in the dark or treated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea and cycloheximide in light. In contrast, in the mutant lacking CCM1, a master regulator of CCM, LCIB remained dispersed even at 4.3 µM CO2. Meanwhile, a simultaneous expression of LCIC, an interacting protein of LCIB, induced the localization of several speckled structures at the pyrenoid periphery. These results suggest that the localization changes of LCIB require LCIC and are controlled by CO2 concentration with ∼7 µM as the boundary.Team-based models that use medical assistants (MAs) to provide self-management support for adults with type 2 diabetes (T2D) have not been pragmatically tested in diverse samples. This cluster-randomized controlled trial compares MA health coaching with usual care in adults with T2D and poor clinical control ("MAC Trial"). The purpose was to conduct a multi-method process evaluation of the MAC Trial using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Reach was assessed by calculating the proportion of enrolled participants out of the eligible pool and examining representativeness of those enrolled. Key informant interviews documented adoption by MA Health Coaches. We examined implementation from the research and patient perspectives by evaluating protocol adherence and the Patient Perceptions of Chronic Illness Care (PACIC-SF) measure, respectively. Findings indicate that the MAC Trial was efficient and effective in reaching patients who were representative of the target population. The acceptance rate among those approached for health coaching was high (87%). Both MA Health Coaches reported high satisfaction with the program and high levels of confidence in their role. The intervention was well-implemented, as evidenced by the protocol adherence rate of 79%; however, statistically significant changes in PACIC-SF scores were not observed. Overall, if found to be effective in improving clinical and patient-reported outcomes, the MAC model holds potential for wider-scale implementation given its successful adoption and implementation and demonstrated ability to reach patients with poorly controlled T2D who are at-risk for diabetes complications in diverse primary care settings.
The pathogenic Leptospira can survive and contaminate surface water based on physicochemical factors. This study aimed to determine how the physicochemical properties of water sources influence the growth and effect of iron on the gene expression of Leptospira spp. P47.

Surface water samples (n=55) were collected and used for Leptospira spp. P47 cultivation. Physicochemical factors, including iron, calcium, magnesium and pH, were analyzed. The association between Leptospira spp. P47 viability at days 5, 10 and 15 with the physicochemical factors were analyzed. In addition, this bacterium was cultured in six selected water samples. The effect of iron in water on HemO and LipL32 gene expression was determined by relative quantification real-time PCR.

Leptospira viability at day 5 was not significantly correlated with physicochemical factors, while Leptospira viability at day 10 was associated with both pH and iron. The Leptospira viability rate at day 15 had a significantly positive association with pH and iron and a negative association with calcium. HemO expression was significantly increased, mostly in selected water samples and under iron-depleted conditions. Conversely, LipL32 expression was significantly decreased in all water samples.

Physicochemical factors in natural surface waters are key factors for bacterial survival in the environment, which may increase the chance of Leptospira infection in humans.

The present article shares findings from a nationwide survey of 1,275 school social workers (SSWs) reporting on their clients-schools, children, and families-during the spring 2020 COVID-19 school closures. SSWs indicated that the children and families they served had significant unmet basic needs, including for food, healthcare, and housing. Poverty and mental health compounded pandemic difficulties, which were associated with the sociodemographic makeup of schools. Student engagement in social work services during the closures was significantly lower than prepandemic levels, generally due to unmet material needs. Several policy and practice implications arise from these findings, including a need for additional services for students and families, a plan to address structural inequities in our schools and communities, coordinated outreach to reengage missing students, and recognition of the strong work being done by school staff coupled with a need for additional supports and resources to combat persistent inequality.
The aim of this study is to show that human T-cell lymphotropic virus type 2 (HTLV-2) infection produces symptoms resembling those described for HTLV-1-associated myeloneuropathy and to highlight the role of sexual transmission in the silent dissemination of HTLV-2.

Patient samples were tested by particle agglutination and indirect immunofluorescence assay. The HTLV type was defined by molecular techniques. Nucleotide sequence analysis of HTLV-2 long terminal repeat region, T cell CD3/CD4 and T cell CD3/CD8 counts and typing of human leucocyte antigen (HLA) alleles A, B, C and DRB1 were also performed.

HTLV-2 subtype b infection was confirmed in two blood donors and their sexual partners. Two patients exhibited distinctive signs and symptoms of progressive neurological disease. Three infected patients carried HLA-C*04. Both patients with neurological disease also carried HLA-A*31 and HLA-DRB1*07 alleles.

Herein we describe for the first time sexual transmission of HTLV-2 in a non-endemic region of Argentina, highlighting the relevance of this transmission route in HTLV-2 silent dissemination out of the clusters of endemicity. We also provide evidence that HTLV-2 infection causes symptoms resembling those described for HTLV-1-associated myeloneuropathy. The evidence presented herein points to the critical need for public health strategies to reduce the spread of this neglected infection.
