ABSTRACT: Acacia mearnsii De Wild. (Black wattle) is a forest species with great social and economical importance for the southern region of Brazil. This species has multifunctional characteristics, being cultivated to produce tannin, cellulose and energy. This research identified black wattle genotypes with competence for adventitious rooting for mini-cutting propagation. Single-bud mini-cuttings were treated with IBA at a concentration of 2000 mg L-1. After 30 days of cultivation in a humid chamber, the mini-cuttings were evaluated for percentages of survival, rooting, number of roots, average length of the three largest roots, and the number of mini-cuttings rooted per mini-stump. The identification of the best genotypes was performed with the Selegen REML/BLUP software. Selection between and within black wattle progenies can be performed based on the number of rooted mini-cuttings, making it possible to select genotypes with high competence for adventitious rooting while maintaining genetic variability for new selection cycles to develop clones for vegetative propagation by mini-cutting.

Coulometry is a well-established technique for certified reference materials (CRM). However, commercial coulometers are currently expensive and utilize outdated software. The National Metrology Institute of Colombia (INMC) has developed a cheaper and modular coulometer with powerful software capable of controlling the instrument, and acquiring pH, the potential difference between generator electrodes, and the electrical current at any stage of the coulometric titration. The results obtained from this new coulometer align well with the novel method for calculating the amount of substance content of potassium hydrogen phthalate (KHP). This method involves the experimental data fitting with the theoretical titration curve TC(NLR), also developed by the INMC. TC(NLR) replaces the traditional empirical W-function (eWf), which has no chemical basis and does not account for CO2 as an impurity. The KHP content of the CRM KHP 84L from NIST was measured using the developed coulometer, resulting in 4.9069 ± 0.0090 mol kg-1 with a bias of 0.21% for the eWf, and a more accurate result of 4.8983 ± 0.0047 mol kg-1 with a bias of 0.041% for the TC(NLR). The challenges during the development of the coulometer, particularly in terms of instrumentation, as well as their impact on uncertainty, are also discussed. wellestablished established CRM. .

Abstract Population growth combined with the need for electrical energy resulted in the construction of hundreds of hydroelectric plants in the state of São Paulo, Brazil. The consequence of these interventions was the fragmentation of rivers, forming barriers, that hinder the mobility of migratory fish species, generating an impact on the life cycle of these species, especially about movement between breeding and feeding areas. For this reason, this article aimed to evaluate the state-of-the-art knowledge regarding dams, free stretches, and migratory species in the three main river basins of the state of São Paulo and its tributaries. Through a systematic review from 2003 to 2023, 89 articles were obtained, 48 of which were about dams, 5 which addressed fish transposition systems, and 36 portraying migratory species. In the first half, research focused more on the impacts of dams on fish fauna, while in the second half of the period studied, studies of migratory fish were dominant. Most research was conducted in the main rivers, with few in the tributaries. Finally, 16 migratory species, considered long-distance, were studied, the most studied being P. lineatus, P. maculatus, L. friderici, M. obtusidens and S. hilarri and the ones that occurred most frequently in rivers are Prochilodus lineatus, Pimelodus maculatus, Megaleporinus obtusidens and Salminus hilarii. Therefore, we recommend maintaining the natural flow regime that still exists in the main rivers and tributaries of the state of São Paulo, to maintain healthy populations of the inventoried species.

Resumo O crescimento populacional aliado à necessidade de energia elétrica resultou na construção de centenas de usinas hidrelétricas no estado de São Paulo, Brasil. A consequência dessas intervenções foi a fragmentação dos rios, formando barreiras, que dificultam a mobilidade das espécies de peixes migradores, gerando impacto no ciclo de vida dessas espécies, principalmente no que diz respeito à movimentação entre áreas de reprodução e alimentação. Por esse motivo, objetivou-se atraves desse artigo avaliar o estado da arte do conhecimento a cerca dos barramentos, trechos livres e espécies migradoras nas três principais bacias hidrográficas do estado de São Paulo e seus tributários. Através de uma revisão sistemática do periodo de 2003 a 2023 foram obtidos 89 artigos, sendo 48 sobre barramentos, 5 que abordavam sistemas de transposição de peixes e 36 retratando as espécies migradoras. Na primeira metade as pesquisas focaram mais os impactos dos barramentos na ictiofauna, enquanto que na segunda metade do período estudado, estudos dos peixes migradores foram dominantes.

The appropriate management of the habitat of the endangered and endemic White-spotted Ketsi Blue butterfly, Lepidochrysops ketsi leucomacula Henning & Henning, 1994, is necessary for its survival. Much of the life history and ecology of this butterfly are unknown. The oviposition plant was found to be Selago tarach-odes Hilliard and the plants that were observed to be visited by L. k. leucomacula for nectar all had pink flowers. Monitoring of two populations of L. k. leucomacula in protected areas commenced in March 2022. Surveillance and walked transects were the monitoring methods used. Observed threats to this endangered butterfly in protected areas were uncontrolled grazing by domestic livestock and mowing of its grassland habitat. Fencing of its grassland habitat may be a way to control these threats.

BACKGROUND: Neonatal hypoxic ischaemic encephalopathy (HIE) is a leading cause of term neonatal death worldwide, with a higher incidence in low- to middle-income settings OBJECTIVE: To investigate whether nucleated red blood cell (nRBC) counts could predict severity of HIE and outcomes in term neonates treated with therapeutic hypothermia (TH METHODS: We conducted a retrospective sub-study at Tygerberg Hospital in Cape Town, South Africa. The review included all cooled neonates' clinical records and blood samples from a National Health Laboratory Services database. One experienced neurodevelopmental expert assessed patients over a period of 12 months RESULTS: Twenty-five files out of a total of 100 were excluded owing to missing data. In accordance with the Thompson HIE score, the cohort was classified as mild (56%), moderate (27%), and severe (17%). All included patients (n=75) had full blood counts within 6 hours of delivery. nRBC were detected in 52% of the samples. There was no correlation between nRBC category and HIE severity (p=0.265). Raised nRBCs (>30 cells/100 white blood cells (WBCs)) were more frequent in infants who died than in those who survived (p=0.008). Infants with nRBC counts >30 cells/100 WBCs had an increased likelihood of having cerebral palsy or impaired neurodevelopment (p=0.013 CONCLUSION: The study demonstrated a significant association between an early increase in nRBC counts in HIE infants treated with TH, and both short- and long-term outcomes. A larger multicentre study is required to better understand the relationship between nRBC counts and HIE in the era of cooling in our local setting

ABSTRACT: The buccal adipose body (BAB) is a well- defined multilobulated adipose component, located bilaterally in the facial region, closely related to nervous and vascular structures. BAB removal is a widely studied procedure in the field of maxillofacial surgery, used mainly to cover defects. Its influence on facial aesthetics has started to popularize the removal of the BAB buccal extension to obtain a more stylized face, an intervention widely known as minimally invasive and without complications. The objective of this study was to collect and evaluate studies that report and evaluate complications associated with the removal of BAB for cosmetic reasons. The evidence was reviewed in the Medline databases via PubMed, Epistemonikos, Scopus, and Google Scholar, using predefined terms, selecting primary studies from case reports. 7 articles with a total of 10 patients were included; Of these, eight patients underwent this procedure in Brazil, one in the United States, and one in Chile. The distribution of the population was 3:7 between men and women with an average age of 35 years and a range between 23 to 49 years. In relation to the reported complications, 100 % of the patients presented facial asymmetry, 80 % presented facial edema, 30 % manifested sialocele, trismus 20 %, 40 % presented hematoma, 20 % compromised general state, 20 % presented dysphagia, in the cases of hypoesthesia, paresthesia, abscess, seroma, facial paralysis, odynophagia, fever were expressed in 10 % of the studied population. All the studies described a surgical reintervention after cosmetic removal of the bichat adipose body. The scarce literature and its low quality do not allow estimating the real percentage of possible complications, nor is it possible to determine their long-term results since there is no evidence of appropriate follow-up for these patients.

RESUMEN: El cuerpo adiposo de la boca (CAB) es un componente adiposo multilobulado bien delimitado, localizado de manera bilateral en la región facial íntimamente relacionado a estructuras nerviosas y vasculares. La remoción de CAB es un procedimiento ampliamente estudiado en el campo de la cirugía maxilofacial, utilizado principalmente para cubrir defectos. Su influencia en la estética facial ha iniciado una popularización de la remoción de la extensión bucal de CAB para obtener un rostro más estilizado, intervención difundida como poco invasiva y sin complicaciones. El objetivo de este estudio fue recopilar y evaluar estudios que reporten y evalúen complicaciones asociadas a la remoción por razones estéticas de CAB. Se revisó la evidencia en las bases de datos Medline vía PubMed, Epistemonikos, Scopus y Google Scholar, utilizando términos predefinidos, seleccionando estudios primarios de reportes de casos. Se incluyeron 7 artículos con un total de 10 pacientes; de estos, ocho pacientes se realizaron este procedimiento en Brasil, uno en Estados Unidos y uno en Chile. La distribución de la población fue de 3:7 entre hombres y mujeres con edad promedio de 35 años y un rango entre los 23 a los 49 años. En relación a las complicaciones reportadas, 100 % de los pacientes presentaron asimetría facial, un 80 % presentó edema facial, 30 % manifestaron sialocele, Trismus 20 %, 40 % presentó hematoma, 20 % compromiso del estado general, 20 % presentaron disfagia, en los casos de hipoestesia, parestesia, absceso, seroma, parálisis facial, odinofagia, fiebre se expresaron en 10 % de la población estudiada. En todos los estudios se describió una reintervención quirúrgica posterior a la remoción estética del cuerpo adiposo de bichat. La escasa literatura y la baja calidad de esta, no permite estimar el porcentaje real de posibles complicaciones, tampoco es posible determinar sus resultados a largo plazo ya que no existe en la evidencia un seguimiento apropiado para estos pacientes.

In 2019, Discovery Health published a risk adjustment model to determine standardised mortality rates across South African private hospital systems, with the aim of contributing towards quality improvement in the private healthcare sector. However, the model suffers from limitations due to its design and its reliance on administrative data. The publication's aim of facilitating transparency is unfortunately undermined by shortcomings in reporting. When designing a risk prediction model, patient-proximate variables with a sound theoretical or proven association with the outcome of interest should be used. The addition of key condition-specific clinical data points at the time of hospital admission will dramatically improve model performance. Performance could be further improved by using summary risk prediction scores such as the EUROSCORE II for coronary artery bypass graft surgery or the GRACE risk score for acute coronary syndrome. In general, model reporting should conform to published reporting standards, and attempts should be made to test model validity by using sensitivity analyses. In particular, the limitations of machine learning prediction models should be understood, and these models should be appropriately developed, evaluated and reported.

BACKGROUND There is interest in lingering non-specific symptoms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, referred to as Long coronavirus disease 2019 (Long COVID-19). It remains unknown whether the risk of Long COVID-19 is associated with pre-existing comorbidities or initial COVID-19 severity, including infections due to new Omicron lineages which predominated in 2023. OBJECTIVES The aim of this case report was to characterize the clinical features of acute XBB.1.5 infection followed by Long COVID-19. METHODS We followed a 73-year old female resident of Rio de Janeiro with laboratory-confirmed SARS-CoV-2 during acute infection and subsequent months. The SARS-CoV-2 lineage was determined by genome sequencing. FINDINGS The participant denied comorbidities and had completed a two-dose vaccination schedule followed by two booster doses eight months prior to SARS-CoV-2 infection. Primary infection by viral lineage XBB.1.5. was clinically mild, but the participant subsequently reported persistent fatigue. MAIN CONCLUSIONS This case demonstrates that Long COVID-19 may develop even after mild disease due to SARS-CoV-2 in fully vaccinated and boosted individuals without comorbidities. Continued monitoring of new SARS-CoV-2 lineages and associated clinical outcomes is warranted. Measures to prevent infection should continue to be implemented including development of new vaccines and antivirals effective against novel variants. nonspecific non specific SARSCoV2 SARSCoV SARS CoV (SARS-CoV-2 201 COVID19.

This study aimed to determine the seroprevalence levels of Toxoplasma gondii in small ruminants (goats and sheep) and the associated risk factors in the Khomas region of Namibia. A total of 299 and 345 sheep and goat sera from 22 farming establishments were tested, respectively. An IDEXX Toxotest Ab®, a commercial ELISA kit, was used to screen for IgG antibodies to T.gondii. Overall, 3.68% (11/299) of the sheep sera were positive, and 61.54% (8/13) of the sheep flocks tested had at least one positive animal. Only one of the 345 goat sera from 19 flocks was positive, giving animal-level and herd-level prevalences of 0.29% and 5.26%, respectively. Sheep flocks had significantly greater animal-level and flock-level prevalences than goats (p < 0.05) and were 13.14 times more likely to be seropositive (OR = 13.14; CI 95%: 1.686-102.382) than goat flocks. A questionnaire was also administered to identify any putative risk factors associated with seropositivity. Eight risk factors were evaluated, including the total number of goats, total number of sheep, farm size, average rainfall, presence of wild Felidae (African lions, caracals, cheetahs and leopards), presence of domesticated and stray cats and history of abortions in the flocks. Seropositivity to T. gondii in sheep was positively associated with the total number at the farming establishment, history of abortions and farm size (p < 0.05), but not with goats. The study determined that sheep in the Khomas region were probably more exposed to T. gondii infection than goats. It also found T. gondii seroprevalences that were much lower than those in similar studies from other countries in the sub-region and elsewhere.

BACKGROUND: Fibromyalgia Syndrome (FMS) has been linked to decreased social functioning, poor mental health, and quality of life (QOL). Increased physical functioning and activity can result in improvements in social, mental and overall health, as well as lowered depression and anxiety levels OBJECTIVES: The aim of this study was to determine physical activity levels and QOL amongst patients diagnosed with fibromyalgia in the Johannesburg region of South Africa METHODS: The research design was cross-sectional. Descriptive and quantitative data were collected. FMS patients (n=38) completed an online questionnaire on the Google Forms platform. The questionnaire was comprised of four components, namely Demographics, the Global Physical Activity Questionnaire (GPAQ), the Fibromyalgia Impact Questionnaire (FIQR), and the Short Form-36 (SF-36). During data analysis, descriptive characteristics and correlations were computed. The significance level was set at p < 0.05 RESULTS: Results revealed high FIQR scores (67%) accompanied with low QOL scores (<50% in all domains). There was no correlation between physical activity and FIQR, and physical activity and QOL CONCLUSION: High scores on the impact of FMS were associated with lower overall QOL scores. However, the relationship between physical activity, and the impact of FMS and QOL remain inconclusive

BACKGROUND: By using complementary therapies, such as exercise rehabilitation during and after cancer treatment, breast cancer patients and survivors can improve their quality of life and overall health while also negating the deleterious effects of breast cancer and its treatment. OBJECTIVES: The aim of this study was to determine the physical activity levels of female breast cancer patients and survivors in Ekurhuleni, South Africa. METHODS: The International Global Physical Activity Questionnaire (2002) determined participants' physical activity levels during work, travel and leisure. The questionnaire was disseminated to medical facilities in hard copy format and online via the Google Forms platform. Statistics were computed using the Statistical Package for Social Science (SPSS) with the level of significance set at 95% (p < 0.05 RESULTS: One hundred female breast cancer patients and survivors with a mean age of 55 years from Ekurhuleni, South Africa. participated in this study. The findings reflected that most participants (59%) were meeting the American College of Sports Medicine's physical activity guidelines when considering activity done during work, travel and leisure. No significant difference was seen in physical activity participation between breast cancer patients and breast cancer survivors, or those attending private and public facilities. CONCLUSION: For the breast cancer patient, physical activity and exercise may be a promising and effective adjuvant treatment both during and after anticancer therapies, improving quality of life, playing a role in increasing treatment tolerance, mitigating a range of symptoms and side effects brought on by cancer diagnosis and treatments and enhancing outcomes.

RESUMEN Las actitudes del público sobre la genética parecen depender del contexto local. Analizamos las respuestas de una encuesta suministrada en 2015 a 293 residentes de Luján, una ciudad de la provincia de Buenos Aires, Argentina, quienes autoevaluaron su conocimiento sobre genética y su confianza en las pruebas genéticas. La encuesta integraba un proyecto de investigación más amplio en el que los adultos participantes que dieron su consentimiento compartieron información demográfica y genealógica y proporcionaron muestras de saliva para un estudio de ancestría genética. Cuando se les preguntó sobre su conocimiento y confianza, los participantes informaron tener poco conocimiento sobre genética, pero mucha confianza en las pruebas genéticas. Historias muy conocidas de los medios de comunicación sobre investigaciones genéticas forenses basadas en el ADN para identificar a las víctimas de la represión estatal durante la dictadura militar pueden haber contribuido a la alta autoevaluación del propio conocimiento genético manifestado por algunos participantes, independientemente de su nivel educativo. Nuestro análisis proporciona información que podría utilizarse como base para comenzar a desentrañar los niveles actuales de confianza pública en la genética en una región del Sur Global donde las pruebas genéticas se han generalizado, pero el conocimiento y confianza de las personas sobre genética están poco estudiados.

ABSTRACT Public attitudes about genetics appear to depend on the local context. We analyzed survey responses obtained in 2015 from 293 residents of Luján, a city in the province of Buenos Aires, Argentina, who self-assessed their knowledge about genetics and their trust in genetic tests. The survey integrated a larger research project for which consenting adult participants shared demographic and genealogical information and provided saliva samples for genetic ancestry analyses. Participants reported little knowledge but high trust in genetic testing when questioned about knowledge and trust. Well-known media stories of DNA-based forensic genetic investigations to identify the victims of state repression during the military dictatorship may have contributed to the high self-assessment of their genetic knowledge expressed by some participants, regardless of educational attainment. Our analysis provides information that could be used as a baseline to begin unraveling the current level of public trust in genetics in a region of the Global South where genetic testing has become widespread, but people’s knowledge of and trust in genetics remain poorly studied.

ABSTRACT: The supernumerary tooth of nasal location is a pathology of low prevalence in the population with different forms and clinical symptoms. It is important to establish a diagnosis regarding its clinical and radiological characteristics in order to carry out adequate surgical treatment planning, with few or no post-intervention complications. Case presentation: This study reports the case of a 10-year-old boy, with no morbid history, who presented a supernumerary tooth, found radiographically in the midline. CBCT showed a mesiodens in the nasal septum, tilted and inverted palatal, partially erupted covered by nasal mucosa, with its crown facing the nasal cavity in relation to the nostrils. The tooth was extracted under general anesthesia using a transoral approach through a vestibulotomy. The nasal supernumerary tooth is a rare pathology. It is important to know its clinical and radiographic characteristics since they will determine the type of approach to be used. The degree of eruption, the distance to the anterior nasal spine and its associated symptoms are essential to determine whether the surgical approach is intraoral or extraoral.

RESUMEN: El diente supernumerario de ubicación nasal es una patología de baja prevalencia en la población con diferentes formas y sintomatología clínica. Es importante establecer un diagnóstico respecto a sus características clínicas y radiológicas para realizar una planificación de tratamiento quirúrgica adecuada, con nula o escasas complicaciones post intervención. Presentación del caso: En el presente estudio se reporta el caso de un niño de 10 años de edad, sin antecedentes mórbidos, que recurre al servicio por presentar un diente supernumerario en la línea media hallado radiográficamente. El CBCT demuestra un mesiodens en el septum nasal, palatal inclinado e invertido, parcialmente erupcionado cubierto por mucosa nasal, con su corona en sentido a la cavidad nasal en relación a las fosas nasales. El diente fue extraído con anestesia general mediante un abordaje transoral a través de una vestibulotomía. El diente supernumerario nasal es una patología poco prevalente. Es importante conocer sus características clínicas y radiográficas ya que determinarán el tipo de abordaje a realizar. El grado de erupción, la distancia a la espina nasal anterior y su sintomatología asociada son fundamentales para determinar si el abordaje quirúrgico es intraoral o extraoral.
