Ending tuberculosis (TB) requires a multisectoral approach, including participation from organized civil society. With the support of a regional project (OBSERVA TB) financed by the Global Fund, TB social observatories have been created since 2019 in eight countries in Latin America and the Caribbean (Bolivia, Colombia, the Dominican Republic, El Salvador, Guatemala, Haiti, Mexico, and Peru), as well as a regional TB social observatory, as part of implementation of the ENGAGE-TB approach promoted by the World Health Organization. This article presents the implementation model, advances, and challenges of TB social observatories. As of December 2021, 135 civil society organizations in Latin America and the Caribbean were included in the eight observatories. These are spaces that serve as platforms for social surveillance, policy advocacy, and social monitoring of national TB responses, in addition to contributing to ENGAGE-TB indicators related to TB case detection and support during treatment. It is recommended to consolidate and expand the existing observatories, with the participation of other countries in the LAC region.

Usefulness of the Measurement of Serum Paraoxonase-1 Arylesterase Activity in the Diagnoses of COVID-19.

The development of inexpensive, fast, and reliable screening tests for COVID-19 is, as yet, an unmet need. The present study was aimed at evaluating the usefulness of serum arylesterase activity of paraoxonase-1 (PON1) measurement as a screening test in patients with different severity levels of COVID-19 infection. We included 615 COVID-19-positive patients who were classified as asymptomatic, mildly symptomatic, severely symptomatic, or fatally symptomatic. Results were compared with 50 healthy volunteers, 330 patients with cancer, and 343 with morbid obesity. Results showed PON1 activity greatly decreased in COVID-19 compared to healthy volunteers; a receiver operating characteristics plot showed a high diagnostic accuracy. The degree of COVID-19 severity did not influence PON1 levels. Our results indicated that PON1 determination was efficient for disease diagnosis, but not for prognosis. Furthermore, patients with obesity or cancer presented alterations similar to those of COVID-19 patients. As such, elevated levels of PON1 indicate the absence of COVID-19, but low levels may be present in various other chronic diseases. The assay is fast and inexpensive. We suggest that PON1 measurement could be used as an initial, high cut-off point screening method, while lower values should be confirmed with the more expensive nucleic acid amplification test.

Families and the Juvenile Justice System: Considerations for Family-Based Interventions.

We conducted focus groups with defense lawyers, clinicians, and education advocates to gather their perspectives on families' experiences with the juvenile justice system. Our quantitative descriptive analysis identified a range of themes such as discussions about the poor treatment of families as well as recommendations for a shifting of power to families. These perspectives may provide insights about the context in which families are expected to participate in interventions, meet probationary demands, and provide for their youth's well-being. The results support evidence gathered from families about the impact of youth incarceration on their lives and has implications for practitioners and researchers working with families whose youth have been incarcerated.

Human Invariant Natural Killer T Cells Respond to Antigen-Presenting Cells Exposed to Lipids from Olea europaea Pollen.

BACKGROUND: Allergic sensitization might be influenced by the lipids present in allergens, which can be recognized by natural killer T (NKT) cells on antigen-presenting cells (APCs). The aim of this study was to analyze the effect of olive pollen lipids in human APCs, including monocytes as well as monocyte-derived macrophages (Mϕ) and dendritic cells (DCs). METHODS: Lipids were extracted from olive (Olea europaea) pollen grains. Invariant (i)NKT cells, monocytes, Mϕ, and DCs were obtained from buffy coats of healthy blood donors, and their cell phenotype was determined by flow cytometry. iNKT cytotoxicity was measured using a lactate dehydrogenase assay. Gene expression of CD1A and CD1D was performed by RT-PCR, and the production of IL-6, IL-10, IL-12, and TNF-α cytokines by monocytes, Mϕ, and DCs was measured by ELISA. RESULTS: Our results showed that monocytes and monocyte-derived Mϕ treated with olive pollen lipids strongly activate iNKT cells. We observed several phenotypic modifications in the APCs upon exposure to pollen-derived lipids. Both Mϕ and monocytes treated with olive pollen lipids showed an increase in CD1D gene expression, whereas upregulation of cell surface CD1d protein occurred only in Mϕ. Furthermore, DCs differentiated in the presence of human serum enhance their surface CD1d expression when exposed to olive pollen lipids. Finally, olive pollen lipids were able to stimulate the production of IL-6 but downregulated the production of lipopolysaccharide- induced IL-10 by Mϕ. CONCLUSIONS: Olive pollen lipids alter the phenotype of monocytes, Mϕ, and DCs, resulting in the activation of NKT cells, which have the potential to influence allergic immune responses.

Tatuagens: A pele como tela de expressão cultural / The skin as screen for cultural expression

A pele é considerada como uma tela sobre a qual se projeta o material inconsciente que constitui o psíquico. Tentamos dar uma explicação ao fenômeno da tatuagem a partir de uma perspectiva cultural, como fenômeno de massa mais do que individual. A tatuagem é vista como um relato. A pele é a nova tela para fixar as experiências não metabolizadas, a nova "tela permanente". Como a parede das cavernas do homem primitivo, a pele é vista agora como tela de expressão cultural da humanidade.

The proposal of this work is to consider the skin as a screen on which the unconscious material is projected. We try to explain the phenomenon of tattoo from a cultural perspective, more than as an individual mass phenomenon. The tattoo is seen as a story. The skin is the new canvas to set non metabolized experiences, the new "permanent screen". As the wall of the caves of primitive man, the skin is now seen as a canvas for cultural expression of humanity.

Immunoproteomic tools are used to identify masked allergens: Ole e 12, an allergenic isoflavone reductase from olive (Olea europaea) pollen.

Proteins performing important biochemical activities in the olive tree (Olea europaea) pollen have been identified as allergens. One novel 37-kDa protein seems to be associated to the IgE-binding profile of a group of patients suffering allergy to peach and olive pollen. Three previously described olive pollen allergens exhibit very similar molecular mass. Our objective was to identify this allergen by using immunoproteomic approaches. After 2D-electrophoresis and mass spectrometry, peptide sequences from several IgE-binding spots, allowed identifying this new allergen, as well as cloning and DNA sequencing of the corresponding gene. The allergen, named Ole e 12, is a polymorphic isoflavone reductase-like protein of 308 amino acids showing 80% and 74% identity with birch and pear allergens, Bet v 6 and Pyr c 5, respectively. A prevalence of 33% in the selected population is in contrast to 4%-10% in groups of subjects suffering from pollinosis. Recombinant allergen was produced in Escherichia coli, and deeply characterised. Immunoblotting and ELISA detection as well as inhibition experiments were performed with polyclonal antisera and allergic patients' sera. The recombinant allergen retains the IgE reactivity of its natural counterpart. Close structural and immunological relationships between members of this protein family were supported by their IgG recognition in vegetable species. In summary, Ole e 12 is a minor olive pollen allergen, which gains relevance in patients allergic to peach with olive pollinosis. Proteomic approaches used to analyse this allergen provide useful tools to identify hidden allergens, relevant for several allergic populations and thus complete allergenic panels.

Olea europaea pollen lipids activate invariant natural killer T cells by upregulating CD1d expression on dendritic cells.

BACKGROUND: Invariant natural killer T (iNKT) cells recognize lipids presented by CD1d and have been implicated in the pathogenesis of allergic asthma. Recognition of plant pollen lipids by iNKT cells and their role in allergic responses are poorly defined. OBJECTIVE: Our goal was to investigate whether iNKT cells can be activated by monocyte-derived dendritic cells (DCs) exposed to lipid antigens from Olea europaea. METHODS: DCs generated in vitro were exposed to O europaea pollen grains or lipids isolated from them. Expression of lipid-presenting molecules (CD1), as well as maturation markers (HLA-DR, HLA-I, CD86, and CD80 molecules), on DCs was analyzed. iNKT cell activation after coculture with DCs was evaluated based on expansion, cytokine production, and cytotoxicity tests. RESULTS: DCs upregulated CD1d and CD86 expression and downregulated CD1a expression after exposure to a whole extract of olive pollen lipids. CD1d and CD1a were regulated at the transcriptional level in a peroxisome proliferator-activated receptor γ activation-dependent manner. Polar lipids, diacylglycerols, free fatty acids, and triacylglycerols isolated from pollen grains upregulate CD1d. The increase in CD1d expression on the DC cell surface induced by polar lipids was not regulated at the RNA level. iNKT cells efficiently recognize DCs treated with the different lipids isolated from olive pollen grains. CONCLUSIONS: Lipids from O europaea pollen upregulate CD1d and CD86 molecules on DCs, which are then able to activate iNKT cells through a CD1d-dependent pathway.

Comparison between two methods of asthma control evaluation based on individual perception.

OBJECTIVE: To compare the subjective perception of asthma control reported by the patient with that measured by the score obtained on the Asthma Control Questionnaire 6-item version (ACQ-6) in patients with severe asthma and to determine whether asthma control is associated with the number of emergency room visits in the previous month. METHODS: This was a cross-sectional study involving 528 patients treated at the Bahia State Asthma and Allergic Rhinitis Control Program Central Referral Clinic between August of 2008 and March of 2010, in the city of Salvador, Brazil. The patients completed the ACQ-6 and answered a specific additional question in order to evaluate their own perception of asthma control in the previous week. RESULTS: We evaluated 423 patients who met the inclusion criteria. The sample was predominantly female (81.3%), and 64.3% had an income lower than two times the national minimum wage. The mean age was 49.85 ± 13.71 years, and the duration of asthma symptoms was 32.11 ± 16.35 years. The patients had been regularly treated via the program for 36.65 ± 18.10 months. Based on the subjective perception of asthma control, only 8% of the patients considered their asthma to be uncontrolled, whereas 38.8% had an ACQ-6 score > 1.5, which indicates poor control. The kappa statistic revealed poor concordance between the two methods. There was a direct association between uncontrolled asthma and the number of emergency room visits in the previous month (p < 0.001). CONCLUSIONS: In this sample of patients, the subjective perception of asthma control differed from that measured by the ACQ-6 score, and the patients overestimated their own level of asthma control, which puts them at risk of being undertreated.

Comparação entre dois métodos de avaliação do controle da asma baseados na percepção individual / Comparison between two methods of asthma control evaluation based on individual perception

OBJETIVO: Comparar a percepção subjetiva do controle da asma informada pelo paciente com aquela obtida por meio do escore do Asthma Control Questionnaire com seis questões (ACQ-6) em pacientes com asma grave e verificar se o controle da asma está associado ao número de visitas a salas de emergência no mês anterior. MÉTODOS: Estudo transversal de 528 pacientes acompanhados na Central de Referência do Programa para Controle da Asma e Rinite Alérgica na Bahia, entre agosto de 2008 e março de 2010, em Salvador (BA). Os pacientes responderam ao ACQ-6 e a uma questão adicional específica para avaliar sua percepção do controle da doença na semana prévia. RESULTADOS: Foram avaliados 423 pacientes, que preencheram os critérios de inclusão. A maioria era do gênero feminino (81,3%) e possuía renda familiar menor que dois salários mínimos (64,3%). A média de idade foi de 49,85 ± 13,71 anos, e a duração dos sintomas de asma foi de 32,11 ± 16,35 anos. Os pacientes eram regularmente tratados no programa há 36,65 ± 18,10 meses. Baseados na percepção subjetiva do controle, 8% dos pacientes consideraram a sua asma não controlada, enquanto 38,8% obtiveram escore do ACQ > 1,5, indicando falta de controle. O coeficiente kappa revelou fraca concordância entre os dois métodos. Houve uma associação direta entre falta de controle e número de visitas a emergência no mês anterior (p < 0,001). CONCLUSÕES: Nesta amostra de pacientes, a percepção subjetiva do paciente sobre o controle da asma diferiu da medida por meio do ACQ-6, e os pacientes superestimaram seu controle, trazendo risco de subtratamento.

Manuseio de dispositivos inalatórios e controle da asma em asmáticos graves em um centro de referência em Salvador / Use of inhaler devices and asthma control in severe asthma patients at a referral center in the city of Salvador, Brazil

OBJETIVO: Avaliar o manuseio dos dispositivos pelos asmáticos graves acompanhados no Programa para o Controle da Asma e Rinite Alérgica na Bahia (ProAR), registrando a frequência dos seus erros em passos essenciais e a relação desses com a falta de controle da asma. MÉTODOS: Estudo de corte transversal com 467 pacientes em acompanhamento no ProAR, na cidade de Salvador (BA). Os dispositivos avaliados foram inalador dosimetrado (ID), em isolado ou com espaçador, e inalador de pó seco (IPS; Pulvinal® ou Aerolizer®). A avaliação da técnica inalatória foi realizada através de uma lista de verificação, sendo solicitado ao paciente que demonstrasse o uso para que um entrevistador observasse todos os passos realizados. Para a avaliação do controle da asma, utilizou-se o questionário de controle da asma com seis questões. RESULTADOS: A maioria dos pacientes demonstrou técnicas inalatórias adequadas no uso dos dispositivos. Poucos erros foram observados na etapa essencial "coordenar disparo e inspiração" no uso de ID isolado e com espaçador (em 5,2 por cento e em 9,1 por cento dos pacientes, respectivamente). No uso de Pulvinal®, 39 por cento dos pacientes não realizaram uma inspiração rápida e profunda, comparados a somente 5,8 por cento no uso de Aerolizer®. Dos pacientes que utilizavam apenas Aerolizer®, 71,3 por cento realizaram adequadamente todos os passos essenciais e estavam controlados. CONCLUSÕES: A maioria dos pacientes desta amostra, os quais eram submetidos a verificações periódicas da técnica inalatória no programa, utilizavam adequadamente os dispositivos. A técnica inalatória adequada está associada ao controle dos sintomas.

OBJECTIVE: To evaluate the use of inhaler devices by patients with severe asthma treated via the Programa para o Controle da Asma e Rinite Alérgica na Bahia(ProAR, Bahia State Asthma and Allergic Rhinitis Control Program), recording the frequency of their errors in performing key steps and the relationship between such errors and the lack of asthma control. METHODS: A cross-sectional study involving 467 patients enrolled in the ProAR in the city of Salvador, Brazil. The devices evaluated were metered dose inhalers (MDIs), with or without a spacer, and dry powder inhalers (DPIs; Pulvinal® or Aerolizer®). For the assessment of the inhalation technique, a checklist was used; the patients were asked to demonstrate the technique so that an interviewer could observe all of the steps performed. For the assessment of asthma control, we used the 6-item asthma control questionnaire. RESULTS: Most of the patients showed appropriate inhalation techniques when using the devices. When using an MDI, few patients made mistakes in the key step of "coordinating activation and inhalation" (5.2 percent and 9.1 percent with and without the use of a spacer, respectively). During Pulvinal® use, 39 percent of the patients did not inhale quickly and deeply, compared with only 5.8 percent during Aerolizer® use. Of the patients that made use of Aerolizer® alone, 71.3 percent appropriately performed all of the essential steps, and their asthma was controlled. CONCLUSIONS: Most of the patients in this sample, all of whom had been submitted to periodic checks of their inhalation technique (as part of the program), used the devices appropriately. Proper inhalation technique is associated with asthma symptom control.

Obesity and poor asthma control in patients with severe asthma.

BACKGROUND: Asthma is a public health problem as it leads to hospitalization and eventual death, particularly in its severe forms. Many studies have demonstrated an association between obesity and asthma. OBJECTIVE: The aim of this study was to investigate the relationship between obesity and asthma control in a group of patients at a reference center for severe asthma in Brazil. METHODS: This cross-sectional study was conducted in the outpatient central reference clinic of the Program for Control of Asthma in the State of Bahia. It included 508 subjects with severe asthma of both genders and above 18 years of age. All the participants answered a sociodemographic and a clinical questionnaire to collect information on their asthma and comorbidities, such as rhinitis and gastro-esophageal reflux disease (GERD). Participants also completed the Asthma Control Questionnaire, performed a spirometry test, and had their weight, height, and waist and hip circumferences registered. RESULTS: Logistic regression analysis demonstrated a positive association between body mass index (BMI) and uncontrolled asthma [odds ratio (OR) 1.5; 95% confidence interval (CI) 1.02-2.20]. Symptoms of chronic rhinitis and GERD were also significantly associated with uncontrolled asthma (OR 3.68, 95% CI 1.50-9.01; and OR 2.78, 95% CI 1.91-4.03, respectively). There was no correlation between waist-to-hip ratios and asthma control. CONCLUSION: In our sample of patients with severe asthma, those who were obese were more likely to have uncontrolled asthma than patients with a normal BMI. Nevertheless, this is not conclusive evidence for a direct causal association between obesity and poor asthma control. Future studies are necessary to dissect the relationship between obesity and asthma outcomes.

Inducible NOS inhibitor 1400W reduces hypoxia/re-oxygenation injury in rat lung.

Nitric oxide (NO(*)) from inducible NO(*) synthase (iNOS) has been reported to either protect against, or contribute to, hypoxia/re-oxygenation lung injury. The present work aimed to clarify this double role in the hypoxic lung. With this objective, a follow-up study was made in Wistar rats submitted to hypoxia/re-oxygenation (hypoxia for 30 min; re-oxygenation of 0 h, 48 h, and 5 days), with or without prior treatment with the selective iNOS inhibitor 1400W (10 mg/kg). NO(*) levels (NOx), lipid peroxidation, apoptosis, and protein nitration were analysed. This is the first time-course study which investigates the effects of 1400W during hypoxia/re-oxygenation in the rat lung. The results showed that the administration of 1400W lowered NOx levels in all the experimental groups. In addition, lipid peroxidation, the percentage of apoptotic cells, and nitrated protein expression fell in the late post-hypoxia period (48 h and 5 days). Our results reveal that the inhibition of iNOS in the hypoxic lung reduced the damage observed before the treatment with 1400W, suggesting that iNOS-derived NO(*) may exert a negative effect on this organ during hypoxia/re-oxygenation. These findings are notable, since they indicate that any therapeutic strategy aimed at controlling excess generation of NO(*) from iNOS may be useful in alleviating NO(*)-mediated adverse effects in hypoxic lungs.

Study of the nitric oxide system in the rat cerebellum during aging.

BACKGROUND: The cerebellum is the neural structure with the highest levels of nitric oxide, a neurotransmitter that has been proposed to play a key role in the brain aging, although knowledge concerning its contribution to cerebellar senescence is still unclear, due mainly to absence of integrative studies that jointly evaluate the main factors involved in its cell production and function. Consequently, in the present study, we investigate the expression, location, and activity of nitric oxide synthase isoenzymes; the protein nitration; and the production of nitric oxide in the cerebellum of adult and old rats. RESULTS: Our results show no variation in the expression of nitric oxide synthase isoforms with aging, although, we have detected some changes in the cellular distribution pattern of the inducible isoform particularly in the cerebellar nuclei. There is also an increase in nitric oxide synthase activity, as well as greater protein-nitration levels, and maintenance of nitrogen oxides (NOx) levels in the senescent cerebellum. CONCLUSIONS: The nitric oxide/nitric oxide synthases system suffers from a number of changes, mainly in the inducible nitric oxide synthase distribution and in overall nitric oxide synthases activity in the senescent cerebellum, which result in an increase of the protein nitration. These changes might be related to the oxidative damage detected with aging in the cerebellum.

Conocimientos de los factores de riesgo asociados al cáncer de mama: Sancti Spíritus 2008 / Knowledge of risk factors associated to breast cancer: Sancti Spíritus 2008

Introducción. El cáncer de mama es una de las neoplasias malignas más frecuentes en Cuba y en el mundo, y sobre todo en nuestro policlínico. Objetivo: Identificar el conocimiento de los principales factores de riesgo asociado al cáncer de mama y el auto examen de la glándula de las féminas del área norte de la ciudad de Sancti-Spíritus. Material y Método. Se realiza esta investigación descriptiva durante el período 2007- 2008. La población la integraron 463 mujeres del área urbana la técnica utilizada fue la entrevista semiestructurada y una guía de observación. Resultados. Se comprobó que la mayoría de estas mujeres desconocen la importancia de realizarse el auto examen de la glándula mamaria para evitar el cáncer de mama y sus complicaciones. El hábito de fumar estaba presente en la mayoría de ellas e incluso estas lo hacían por más de 10 años. Las féminas que no lactaron a sus bebés predominaron sobre las que sí lo hicieron, al explorar el auto examen de mama prevalecieron las que no conocían la forma adecuada ni la periodicidad requerida para el mismo. Conclusiones: Los principales factores de riesgo asociados al cáncer de mama en las féminas estudiadas se encontraron el hábito de fumar y la no lactancia materna, agravado por el desconocimiento que tienen las mujeres para la correcta práctica de la técnica del auto examen de mama, siendo la vía de adquisición de la información más frecuente la radio y la televisión(AU)

Introduction: Breast cancer is one of the most common malignant neoplasias in the world and in Cuba. Objective: To identify the knowledge of the main risk factors associated to breast cancer and self- exam of females of the north area of Sancti-Spíritus city. Material and Method: A descriptive research was made during the period 2007 - 2008. The population was made up of 463 women of the urban area; the technique used was the half-structured interview and an observation guide. Results: It was confirmed that most of these women ignore the importance of making the self- exam of the mammary gland to avoid breast cancer and its complications. The habit of smoking was present in most of them and even they did it for more than 10 years. The females that didn't breastfeed their babies prevailed over those that did breastfeed. On exploring breast self-exam, those that didn't know the appropriate form neither the periodicity required for it prevailed. Conclusions: The main factors of risk associated to breast cancer in the females studied were the habit of smoking and the non-maternal nursing, increased by the ignorance that women have for the correct practice of the breast self-exam technique. The most frequent way of acquisition of the information was radio and television(AU)

Lung eNOS and iNOS are reoxygenation time-dependent upregulated after acute hypoxia.

Nitric oxide plays a critical role in many physiological and physiopathological processes in the lung. Changes in the NO/NOS (Nitric Oxide/Nitric Oxide Synthase) system after hypoxia situations remain controversial in this organ, so that the aim of this work is to perform a complete study of this system in the hypoxic lung after different reoxygenation times ranging from 0 h to 5 days posthypoxia. This is a novel follow-up study carried out in Wistar rats submitted for 30 min to acute hypobaric hypoxia. We measured endothelial and inducible NOS (eNOS, iNOS) mRNA and protein expression, location, and in situ NOS activity as well as nitrated protein expression and location. In addition, NO levels were indirectly quantified (NOx) as well as the apoptosis level. Results showed an increase in eNOS mRNA, protein, activity as well as eNOS positive immunostaining at 0 h posthypoxia, coinciding with raised NOx levels. Contrary, iNOS, nitrated protein expression and apoptosis level augmented during the final reoxygenation times. The lung NO/NOS system provokes two responses to the hypoxia/reoxygenation processes: (i) eNOS is responsible of the immediate response, producing NO, which causes vasodilation and bronchodilation, and (ii) iNOS is related to the second late response, which seems to be involved in some of the deleterious consequences that hypoxia induces in the lung.
