Development and evaluation of a single-tube nested PCR with colorimetric assay for Mycobacterium tuberculosis detection.

Molecular techniques have revolutionized tuberculosis (TB) diagnosis by offering a faster and more sensitive approach, detecting Mycobacterium tuberculosis (Mtb) DNA directly from samples. Single-tube nested PCR (STNPCR) combines two PCR reactions with separate oligonucleotide sets in a single tube. Moreover, colorimetric methods in PCR products have been studied for pathogen detection. Thus, this study aimed to establish a novel system based on colorimetric STNPCR for Mtb detection using microtiter plates with IS6110-amplified fragments. The results showed a general colorimetric STNPCR detection limit of 1 pg/µl. Its general sensitivity and specificity were 76.62 and 60.53%, respectively, with kappa index agreement of 0.166.

Institutional racism at the university and consequences in the lives of Black students: a mixed study. / O racismo institucional na universidade e consequências na vida de estudantes negros: um estudo misto.

This article aimed to analyze how institutional racism at a Brazilian public university affects the lives of Black students. This mixed study was developed by applying an online self-administered questionnaire to university students who self-declared as Blacks. Quantitative data were analyzed using descriptive statistics, bivariate analysis using chi-square, and multinomial logistic regression. Qualitative data analysis was performed using IRAMUTEQ. Sixty-eight (54.4%) of the 125 respondents claimed to have suffered racism at least once within the university. We noticed that racist situations experienced by Black people within the university environment call into question the student's self-confidence and motivation, directly affecting their mental health and performance in the course. The importance of receptive groups for strengthening students' belonging was highlighted.

O objetivo do artigo foi analisar como o racismo institucional em uma universidade pública brasileira afeta a vida de estudantes negros e negras. Trata-se de um estudo misto, desenvolvido por meio da aplicação de questionário autoaplicado online a estudantes universitários que se autodeclararam negros. Os dados quantitativos foram analisados por estatística descritiva, análise bivariável por meio do qui-quadrado e regressão logística multinominal. A análise dos dados qualitativos foi feita no Iramuteq. Do total de 125 respondentes, 68 (54,4%) afirmaram ter sofrido racismo pelo menos uma vez dentro da universidade. Percebeu-se que as situações racistas vividas pelas pessoas negras dentro do ambiente universitário colocam em questão a autoconfiança e a motivação do estudante, afetando diretamente a sua saúde mental e seu desempenho no curso. Evidenciou-se a importância dos coletivos para acolhimento e fortalecimento do pertencimento dos estudantes.

Changes in bryophyte functional composition during post-fire succession.

Climate and land-use changes are altering fire regimes in many regions around the world. To date, most studies have focused on the effects of altered fire regimes on woody and herbaceous communities, while the mechanisms driving post-fire bryophyte succession remain poorly understood, particularly in Mediterranean-type ecosystems. Here, we examined changes in bryophyte functional composition along a post-fire chronosequence (ranging from 1 to 20+ years) in Pyrenean oak woodlands (northeastern Portugal). To do so, we defined bryophyte functional groups based on seven morphological, reproductive, and life history traits. Then, we fitted linear and structural equation models to disentangle the direct and indirect effects of fire (time since fire and fire intensity), vegetation structure, climate, topography, and edaphic conditions on the abundance of each group. We identified two main functional groups: early colonizers (species with traits associated with strong colonization ability and desiccation tolerance) and perennial stayers (species with high competitive ability, i.e., large perennial mosses). Overall, the abundance of early colonizer species decreased with time since fire and increased with fire intensity, while the opposite was observed for perennial stayers. Thus, successional dynamics reflected a trade-off between species' competitive and colonization abilities, highlighting the role of biotic interactions later in succession. Patterns of functional composition were also consistent with changes in environmental conditions during succession, suggesting that species may experience stressful conditions (i.e., high radiation and low water availability) in early stages of post-fire succession. Our results also indicate that increased fire intensity may alter successional trajectories, leading to long-term changes in bryophyte communities. By understanding the response of bryophyte communities to fire, we were able to identify species with potential use as soil restoration materials.

Partners with a Highly Favorable Attitude Toward Breastfeeding Contribute to Promoting Initiation and Length of Breastfeeding for More than 5 Months in a Population-Based Canadian Study.

Introduction: Promoting maternal breastfeeding for at least 6 months is important to improve children physical health during infancy and neurodevelopmental outcomes in childhood. For this guideline to be followed, it is paramount to identify what factors best support the initiation and length of breastfeeding. This study estimates the contribution of various child- and parent-level factors, as well as the sociodemographic context in predicting maternal breastfeeding initiation and duration. Methods: This study draws on data from the Quebec Longitudinal Study of Child Development. Mothers who never breastfed when the infant was 5 months old (n = 630, 28.3%) were compared to mothers who breastfed for less than 5 months (n = 844, 38.0%) and mothers breastfeeding for more than 5 months (n = 749, 33.7%), using multivariable multinomial regression models. Results: Mothers with a partner showing a positive attitude toward breastfeeding were up to 13 times more likely to breastfeed their infant for more than 5 months. The positive attitude of partners toward breastfeeding was the strongest predictor of breastfeeding duration, followed by the maternal educational attainment and timing she returns to work. Most prenatal and perinatal child-level factors and the sociodemographic context predicted breastfeeding duration, but to a lesser extent. Discussion: This finding underscores the role of the partner's attitude in promoting initiation and length of breastfeeding. As such, educational campaigns and health practitioners could target both the mother and their partner in promoting breastfeeding.

Puerperal women's social interactions related to their sexual health after childbirth.

OBJECTIVE: To analyze puerperal women's experiences of sexual health after childbirth from the perspective of symbolic interactionism. METHOD: Descriptive, qualitative study. Twenty semi-structured interviews were conducted by videoconference with women in the remote puerperium, captured by snowball technique and searched for "seeds" on Instagram®. Bardin's content analysis and Symbolic Interactionism were used as references. RESULTS: The puerperal women signify sexual health from a perspective of comprehensive healthcare. However, due to the duality between "being a woman" and "being a mother", they recognize fear, bodily transformations and changes in focus from the love relationship to caring for the baby as factors that interfere with sexual health. And they choose to put themselves aside, prioritizing caring for others. They re-signify sexual health by recognizing the importance of taking care of themselves in biopsychosocial aspects and try to recover self-care for a healthy sexual experience. CONCLUSION: Despite the meanings attributed, women's social interactions with the puerperium interfere negatively with sexual health. Professionals should be sensitized to the inclusion of actions that promote changes in the social action of these women towards self-care.

Cat behaviour in the secure base test: Comparison between owned and shelter animals.

The aim of the present study was to compare affiliative behaviours of owned and shelter cats directed to human in a novel environment after a brief temporary absence of the person. A sample of 20 owned and 20 shelter animals were individually tested in a Secure Base Test, with three 2-min episodes: 1) cat accompanied by a person who sits on the floor inside a circle, 2) the person leaves and the animal is left alone, 3) the person returns, and sits inside the circle again. Three categories were used for coding videotapes of experimental sessions: (1) inside circle, (2) allo-rubbing and (3) tail up. Shelter animals showed more proximity maintenance and affiliative signs with a person than owned animals. Our findings suggested similarities between the secure base effect in cats and in human children: cats seek proximity and maintain contact with a person, displaying affiliative signs to the person, especially after being left alone frightened by an unfamiliar environment.

Incidence of Human and Free-Ranging Wild Rodent Infections with Leishmania (Viannia) braziliensis, Aetiological Agent of Cutaneous Leishmaniasis.

BACKGROUND: Human and wild rodent infection rates with Leishmania (Viannia) braziliensis are needed to differentiate transmission pathways in anthropogenically altered habitats. METHODS: Human participants in northeast Brazil were tested by the leishmanin skin test (LST) and inspected for lesions/scars characteristic of American clinical leishmaniasis (ACL). Molecular (PCR/qPCR) test records of free-ranging rodents were available from a concurrent capture-mark-recapture study. Force of Infection (λ) and recovery (ρ) rates were estimated from cross-sectional and longitudinal datasets. RESULTS: Cumulative prevalences of human LST+ves and ACL scar+ves were 0.343-0.563 (n = 503 participants) and 0.122-0.475 (n = 503), respectively. Active ACL lesions were not detected. Annual rates of LST conversions were λ = 0.03-0.15 and ρ = 0.02-0.07. The probability of infection was independent of sex and associated with increasing age in addition to the period of exposure. Rodents (n = 596 individuals of 6 species) showed high rates of exclusively asymptomatic infection (λ = 0.222/month) and potential infectiousness to the sand fly vector. Spatially concurrent rodent and household human infection prevalences were correlated. CONCLUSIONS: Human exposure to L. (V.) braziliensis continues to be high despite the substantial drop in reported ACL cases in recent years. Spill-over transmission risk to humans from rodents in peridomestic habitats is likely supported by a rodent infection/transmission corridor linking houses, plantations, and the Atlantic Forest.

An Intelligent System to Improve Diagnostic Support for Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma (OSCC) is one of the most-prevalent cancer types worldwide, and it poses a serious threat to public health due to its high mortality and morbidity rates. OSCC typically has a poor prognosis, significantly reducing the chances of patient survival. Therefore, early detection is crucial to achieving a favorable prognosis by providing prompt treatment and increasing the chances of remission. Salivary biomarkers have been established in numerous studies to be a trustworthy and non-invasive alternative for early cancer detection. In this sense, we propose an intelligent system that utilizes feed-forward artificial neural networks to classify carcinoma with salivary biomarkers extracted from control and OSCC patient samples. We conducted experiments using various salivary biomarkers, ranging from 1 to 51, to train the model, and we achieved excellent results with precision, sensitivity, and specificity values of 98.53%, 96.30%, and 97.56%, respectively. Our system effectively classified the initial cases of OSCC with different amounts of biomarkers, aiding medical professionals in decision-making and providing a more-accurate diagnosis. This could contribute to a higher chance of treatment success and patient survival. Furthermore, the minimalist configuration of our model presents the potential for incorporation into resource-limited devices or environments.

Assisting Homeless Women in a City in Brazil during the COVID-19 Pandemic in the Context of a Street Outreach Office: The Perceptions of Health Professionals.

This study aimed to understand the perception of Street Outreach Office professionals regarding the health care offered to homeless women during the COVID-19 pandemic. This is a qualitative and descriptive study developed with nine health professionals of a Street Outreach Office team from a large city in the countryside of São Paulo State (Brazil) from December 2020 to April 2021. Data were obtained through interviews using a semi-structured script with questions about care practices directed to homeless women. The data were analyzed according to content analysis in the thematic modality. Two thematic categories were identified: (i) the reorganization of the Street Outreach Office to meet the demands of the population and (ii) the challenges in caring for homeless women during the pandemic. The activities were intensified with the team's expansion and distribution of supplies such as masks and alcohol-based hand sanitizers. Our findings showed that the primary problem faced was pregnancy during the pandemic. The lack of material and structural resources and social apparatus to care for homeless women was also evidenced. It was possible to conclude that even with all the adversities, the professionals employed creative strategies, contributing, within their limitations, to the care of homeless women.

Machine learning for industrial processes: Forecasting amine emissions from a carbon capture plant.

One of the main environmental impacts of amine-based carbon capture processes is the emission of the solvent into the atmosphere. To understand how these emissions are affected by the intermittent operation of a power plant, we performed stress tests on a plant operating with a mixture of two amines, 2-amino-2-methyl-1-propanol and piperazine (CESAR1). To forecast the emissions and model the impact of interventions, we developed a machine learning model. Our model showed that some interventions have opposite effects on the emissions of the components of the solvent. Thus, mitigation strategies required for capture plants operating on a single component solvent (e.g., monoethanolamine) need to be reconsidered if operated using a mixture of amines. Amine emissions from a solvent-based carbon capture plant are an example of a process that is too complex to be described by conventional process models. We, therefore, expect that our approach can be more generally applied.

High levels of infectiousness of asymptomatic Leishmania (Viannia) braziliensis infections in wild rodents highlights their importance in the epidemiology of American Tegumentary Leishmaniasis in Brazil.

BACKGROUND: The epidemiological significance of wildlife infections with aetiological agents causing human infectious diseases is largely determined by their infection status, contact potential with humans (via vectors for vector-borne diseases), and their infectiousness to maintain onward transmission. This study quantified these parameters in wild and synanthropic naturally infected rodent populations in an endemic region of tegumentary leishmaniasis in northeast Brazil. METHODS: Capture-mark-recapture (CMR) of rodents was conducted over 27 months in domestic/peri domestic environs, household plantations and nearby Atlantic Forest (9,920 single trap nights). Rodent clinical samples (blood and ear tissue) were tested for infection by conventional PCR and quantitative PCR (qPCR) for Leishmania (Viannia) braziliensis, and xenodiagnosis to measure infectiousness to the local sand fly vector. RESULTS: A total 603 individuals of 8 rodent species were (re)captured on 1,051 occasions. The most abundant species were Nectomys squamipes (245 individuals, 41% of the total catch), Rattus rattus (148, 25%), and Necromys lasiurus (83, 14%). All species were captured in greater relative frequencies in plantations; R. rattus was the only species captured in all three habitats including in and around houses. Four species, comprising 22.6% of individuals captured at least twice, were geolocated in more than one habitat type; 78.6% were infected with L. (V.) braziliensis, facilitating inter-species and inter-habitat transmission. Species specific period prevalence ranged between 0%-62% being significantly higher in N. squamipes (54-62%) and Hollochillus sciureus (43-47%). Xenodiagnosis was performed on 41 occasions exposing 1,879 Nyssomyia whitmani sand flies to five rodent species (37 individuals). Similar mean levels of infectiousness amongst the more common rodent species were observed. Longitudinal xenodiagnosis of the N. squamipes population revealed a persistent level of infectiousness over 13 months follow-up, infecting a median 48% (IQR: 30.1%-64.2%) of exposed blood-fed vectors. The proportion of exposed flies infected was greater in the low compared to in the high seasonal period of vector abundance. L. (V.) braziliensis parasite loads in rodent blood quantified by qPCR were similar across rodent species but did not represent a reliable quantitative marker of infectiousness to sand flies. The standardised risk of rodent infection in plantations was 70.3% relative to 11.3% and 18.4% in peri domestic and forest habitats respectively. R. rattus was the only exception to this trend indicating greatest risk in the peri domestic environment. CONCLUSIONS: The results support the view that a collective assemblage of wild and synanthropic rodent species is an important wild reservoir of L. (V.) braziliensis in this region, with N. squamipes and R. rattus probably playing a key role in transmission within and between habitat types and rodent species. Rodents, and by implication humans, are at risk of infection in all sampled habitats, but more so in homestead plantations. These conclusions are based on one of the longest CMR study of small rodents in an American Tegumentary Leishmaniasis (ATL) foci.

Abstract Objective To identify the race/color self-reported by women 60 days postpartum; to identify the prevalence of signs of depressive disorder among these women and to verify the association between signs of depressive disorder and the self-reported race/color. Methods Cross-sectional study carried out in a noncapital city in the state of São Paulo. An instrument with sociodemographic data and the Edinburgh Postnatal Depression Scale were used for data collection. Data was analyzed using the Statistical Package for Social Sciences, SPSS, version 17.0. Results A total of 186 women participated in this study, 60.8% reported being brown, 24.2% had signs of depressive disorder and, among these, 81.7% were black. Signs of depressive disorder were associated with the variables: number of children (p=0.006), planned pregnancy (p=0.04) and type of delivery (p< 0.001). Conclusion The results of this study contribute to greater visibility of the issue of women's mental health, specifically of black women, because even though no significant association was identified among those who showed signs of depressive disorder, most were black.

Characterization of adolescent sexual practices. / Caracterização das práticas sexuais de adolescentes.

OBJECTIVE: to characterize adolescents' sexual practices and their association with sociodemographic variables, sources of information and behavioral habits. METHOD: a descriptive, observational, cross-sectional study conducted with 85 adolescents from public elementary and high schools in a city in the state of São Paulo. Data were collected through a structured, self-administered and anonymous questionnaire. Statistical analysis was performed using the χ2 test and Fisher's test. RESULTS: 21.2% had started their sexual life through oral sex, with a predominance of females (94.4%), self-reported brown color (55.0%). The practice of vaginal sex was reported in 31.8%, with a mean age of initiation at 14.5 years. The female sex was predominant (77.0%), with a self-reported brown color (40.0%). The practice of anal sex was detected in 7.1%, with a mean age of 14.4 years, prevalent in females (83.3%), with a self-reported black color (50.0%). There was an association of alcohol, drugs and tobacco use with sexual practices (p<0.05). CONCLUSION: a diversity of sexual practices associated with substance use was detected, emphasizing the importance of the nurse's role in planning and carrying out health education interventions with adolescents and families.(1) Analysis of the sequence and time of initiation of sexual practices, demonstrating the diversity of sexual activities performed by adolescents. (2) Family context and low openness to dialogue and its correlation with the initiation of adolescent sexual practices. (3) Behavioral habits: association of alcohol, tobacco and drug consumption by adolescents with sexual activities.

Study on the zoonotic cycle of tegumentary leishmaniasis in an endemic area of a metropolitan region in the Northeastern region of Brazil.

This study was conducted to characterize the transmission cycle of the tegumentary leishmaniasis (TL) in an old colonization area at Pernambuco State, Brazil. The aims were to identify autochthonous cases, sandflies fauna, domestic animals as possible reservoir hosts and the Leishmania species involved in this endemic area. A total of 168 suspected human cases of TL and 272 domestic animals (canine, feline, equine, goat, and sheep) were included. The sandflies were captured and identified by species. Patients were predominantly male and the average age was 37+18.1 years old. Of 85 patients who had skin lesions, 25.6% of them had direct positive smears for TL and 34 isolates were identified as Leishmania (Viannia) braziliensis. The confirmation for TL diagnosed by molecular detection (PCR) was almost three times more sensitive than the direct test [p < 0.001; PR = 2.72] associated with clinical examination. The Kappa test on PCR between two different specimens, biopsy, and skin lesion swab was 60.8% (p < 0.001). More than 200 specimens of sandflies (80 males and 159 females) were captured and identified as Lutzomyia whitmani (99.6%) and Lu. evandroi (0.4%). The detection of L. (V.) braziliensis by Real-Time PCR in the blood of a captured fed female was positive in 59.3% of Lu. whitmani. Of the 272 domestic animals included, 61.76% were male (n = 168). Thirty-six animals (13.2%) had lesions compatible with TL (34 dogs, 1 cat and 1 sheep) and 3 of them, all dogs, had lesions on the snout, showing destruction of cartilage and mucosa. The study suggests the participation of domestic animals as possible reservoirs. However, further studies are necessary to better understand the transmission cycle and take recommended measures in order to control the disease.

Attention to Women's Sexual and Reproductive Health at the Street Outreach Office.

The aim of study was to understand care strategies for homeless women, focusing on aspects of sexual and reproductive health from the perspective of Street Outreach Office strategy professionals. This is a qualitative study carried out in a large city in the countryside of São Paulo, Brazil. Data were collected from December 2020 to April 2021 through semi-structured interviews, and the results were obtained through content analysis and thematic modality. Nine health professionals participated in this study, and the analysis of the interviews allowed identifying three thematic categories: (i) being female and sex on the streets (violence and oppression); (ii) gynecology as a gateway to comprehensive care for homeless women; and (iii) pregnancy, puerperium and motherhood in the context of the streets. This study contributes to the reflection of professional practices within the Street Outreach Office, allowing the understanding of challenges in assisting homeless women, aiming to raise awareness of professionals and services that make up the health care network.
