Factors Associated With Elder Abuse According to the Levels of Social Determinants in Brazil.

OBJECTIVE: The aim of this study was to analyze the factors associated with elder abuse according to the levels of social determinants. METHODOLOGY: This is a quantitative and multicentric study, with a cross-sectional cut. It was developed in two teaching hospitals in Paraíba, Brazil, with 323 older adults, from July 2019 to February 2020. Data were collected using the Hwalek-Sengstock Elder Abuse Screening Test and Conflict Tactics Scale-1 and then analyzed using descriptive and inferential statistics. RESULTS: There was a significant association between risk for violence and female gender (p = 0.004), residing with grandchildren (p = 0.025), and having four or more comorbidities (p < 0.00). Physical violence was associated with income (p = 0.048). A positive correlation was observed between the number of comorbidities and the risk for violence score (p < 0.001), psychological violence (p = 0.004), and physical violence (p = 0.005). The probability of presenting a risk to violence increased by 2.08 times for women, 1.03 times for those who were illiterate, and 7.03 times for those with four or more comorbidities. CONCLUSION: The social determinants of health that integrate the macrosystem, such as income and number of comorbidities, correlate with situations of violence.

Risk areas for the occurrence of leprosy in border countries of South America - Brazil and Argentina.

OBJECTIVE: The aim was to analyze the spatial association and relative risk (RR) of leprosy cases diagnosed in southern Brazil and in the Argentinean province of Misiones during 2010 to 2016. METHODS: This ecological-type epidemiological study analyzed data from the Health Ministries of both countries. The analysis included frequency measures, spatial autocorrelation, RR cluster analysis and map construction. RESULTS: A hyperendemic occurrence was identified in all study regions, in the state of Paraná 71.2% of the municipalities were hyperendemic and in Misiones, Argentina 41.2%. The GI* statistical analysis showed clusters of high incidence rates in the state of Paraná and low-risk clusters in much of the state of Rio Grande do Sul, both in Brazil. The analysis indicated an area with RR equal to 3.87 - (p < .0001) when considering the entire territory and an RR of 2.80 - (p < .0001) excluding the state of Paraná, with the number of departments of Misiones, Argentina included in the risk clusters increasing significantly. CONCLUSIONS: The findings indicate a high probability of similar illness in adjacent areas, according to their relative position in space, as the occurrence of the disease is influenced by neighboring clusters.

The genetic mechanisms underlying the convergent evolution of pollination syndromes in the Neotropical radiation of Costus L.

Selection together with variation in floral traits can act to mold floral form, often driven by a plant's predominant or most effective pollinators. To investigate the evolution of traits associated with pollination, we developed a phylogenetic framework for evaluating tempo and mode of pollination shifts across the genus Costus L., known for its evolutionary toggle between traits related to bee and bird pollination. Using a target enrichment approach, we obtained 957 loci for 171 accessions to expand the phylogenetic sampling of Neotropical Costus. In addition, we performed whole genome resequencing for a subset of 20 closely related species with contrasting pollination syndromes. For each of these 20 genomes, a high-quality assembled transcriptome was used as reference for consensus calling of candidate loci hypothesized to be associated with pollination-related traits of interest. To test for the role these candidate genes may play in evolutionary shifts in pollinators, signatures of selection were estimated as dN/dS across the identified candidate loci. We obtained a well-resolved phylogeny for Neotropical Costus despite conflict among gene trees that provide evidence of incomplete lineage sorting and/or reticulation. The overall topology and the network of genome-wide single nucleotide polymorphisms (SNPs) indicate that multiple shifts in pollination strategy have occurred across Costus, while also suggesting the presence of previously undetected signatures of hybridization between distantly related taxa. Traits related to pollination syndromes are strongly correlated and have been gained and lost in concert several times throughout the evolution of the genus. The presence of bract appendages is correlated with two traits associated with defenses against herbivory. Although labellum shape is strongly correlated with overall pollination syndrome, we found no significant impact of labellum shape on diversification rates. Evidence suggests an interplay of pollination success with other selective pressures shaping the evolution of the Costus inflorescence. Although most of the loci used for phylogenetic inference appear to be under purifying selection, many candidate genes associated with functional traits show evidence of being under positive selection. Together these results indicate an interplay of phylogenetic history with adaptive evolution leading to the diversification of pollination-associated traits in Neotropical Costus.

Production, concentration and partial characterization of an enzymatic extract produced by an Aspergillus niger mutant in solid state fermentation.

An enzymatic extract from Aspergillus niger 3T5B8 was produced by Solid State Fermentation (SSF) in aerated columns, using wheat bran as substrate. A combination of extracts produced using three different process conditions varying temperature, pH and aeration formed the final extract (Mixture). The Mixture was concentrated by an ultrafiltration process that partially purified and provided an efficient recovery of the enzymatic activities of xylanase (88.89%), polygalacturonase (89.3%), ß-glucosidase (93.15%), protease (98.68%) and carboxymethylcellulase (CMCase) (98.93%). SDS-PAGE analysis showed 15 visible protein bands in the crude and concentrated Mixture with molecular weights ranging from 15.1 to 104.6 kDa. Thin layer chromatography confirmed the effective action of ß-glucosidase and xylanase hydrolysis activities over cellobiose and xylan, respectively. A central composite design (CCD) with two variables and four replicates at the center points was used to determine the optimal temperature and pH for CMCase and ß-glucosidase. The optimal temperature was 78.9 °C and pH 3.8 for CMCase and 52.8 °C and pH 4.8 for ß-glucosidase, respectively.

Chromoblastomycosis in the Amazon region, Brazil, caused by Fonsecaea pedrosoi, Fonsecaea nubica, and Rhinocladiella similis: Clinicopathology, susceptibility, and molecular identification.

Chromoblastomycosis is a chronic subcutaneous disease caused by human contact with melanized fungi occurring mainly in tropical and subtropical zones worldwide. This study assessed 12 patients with chromoblastomycosis from Rondônia, Brazil, Amazon region. In sum, 83.3% were men, 41.6% were from Monte Negro city, median age was 52.9 years, and median time to disease progression was 12.2 years. Lesions were located on the lower limbs (75%), and verruciform was prevalent form (66.6%). After 3 years of treatment with itraconazole, two patients were considered cured. The etiological agents were identified by the molecular sequence of the ribosomal internal transcribed spacer ITS1, 5.8S, and ITS2 region and ß-tubulin genes. Eight strains were identified as Fonsecaea pedrosoi, two were F. nubica, and two were Rhinocladiella similis. The antifungal activity of five drugs was evaluated, and the most active drug was terbinafine (range minimal inhibitory concentration [MIC] 0.015-0.12 µg/ml), itraconazole (range MIC 0.03-0.5 µg/ml) and voriconazole (range MIC 0.06-0.5 µg/ml). The highest MIC was 5-fluorocytosine (range MIC 2-32 µg/ml), and amphotericin B (range MIC 0.25-2 µg/ml). In conclusion, the present study expanded the epidemiological disease database and described for the first time F. nubica and R. similis as chromoblastomycosis agents in the Brazilian Amazon region. Our results confirmed the importance of using molecular methods to identify the melanized fungi and stimulate the recognition of the disease in other places where no cases have been reported.

Bariatric surgery as a treatment for pseudotumor cerebri: case study and narrative review of the literature / Cirurgia bariátrica como tratamento para pseudotumor cerebri: estudo de caso e revisão narrativa de literatura

ABSTRACT CONTEXT: Pseudotumor cerebri occurs when there is an increase in intracranial pressure without an underlying cause, usually leading to loss of vision. It is most commonly observed in obese women of child-bearing age. CASE REPORT: A 46-year-old woman presented at our service with idiopathic intracranial hypertension that had been diagnosed two years earlier, which had led to chronic refractory headache and an estimated 30% loss of visual acuity, associated with bilateral papilledema. She presented partial improvement of the headache with acetazolamide, but the visual loss persisted. Her intracranial pressure was 34 cmH2O. She presented a body mass index of 39.5 kg/m2, also associated with high blood pressure. Computed tomography of the cranium with endovenous contrast did not show any abnormalities. She underwent Roux-en-Y gastric bypass with uneventful postoperative evolution. One month following surgery, she presented a 24% excess weight loss. An ophthalmological examination revealed absence of visual loss and remission of the papilledema. There were no new episodes of headache following the surgery. There was also complete resolution of high blood pressure. The intracranial pressure decreased to 24 cmH2O, six months after the surgery. CONCLUSION: Although the condition is usually associated with obesity, there are few reports of bariatric surgery among individuals with pseudotumor cerebri. In cases studied previously, there was high prevalence of resolution or improvement of the disease following bariatric surgery. There is no consensus regarding which technique is preferable. Thus, further research is necessary in order to establish a specific algorithm.

RESUMO CONTEXTO: O pseudotumor cerebri ocorre quando há aumento na pressão intracraniana sem causa subjacente, comumente levando a perda visual. É mais comum em mulheres obesas em idade fértil. RELATO DE CASO: Mulher de 46 anos, foi admitida com hipertensão intracraniana idiopática diagnosticada há dois anos, que levou a cefaleia refratária crônica e perda estimada de 30% da acuidade visual, associada a papiledema bilateral. Apresentou melhora parcial da cefaleia com acetazolamida, mas a perda visual persistiu. A pressão intracraniana era de 34 cmH2O. Apresentava índice de massa corpórea de 39,5 kg/m2, associado a hipertensão arterial. Tomografia computadorizada com contraste endovenoso de crânio não apresentou anormalidades. Foi submetida ao bypass gástrico em Y de Roux, com evolução pósoperatória sem intercorrências. Um mês após a cirurgia, apresentou perda de peso em excesso de 24%. Um exame oftalmológico demonstrou ausência de perda visual e remissão do papiledema; não houve novos episódios de cefaleia após a cirurgia. Houve também resolução completa da hipertensão arterial. A pressão intracraniana caiu para 24 cmH2O após seis meses da cirurgia. CONCLUSÃO: Embora a condição seja usualmente associada à obesidade, há escassos relatos de cirurgia bariátrica em indivíduos com pseudotumor cerebri. Nos casos previamente estudados, há alta prevalência de resolução ou de melhora da doença após a cirurgia bariátrica. Não há consenso sobre qual é a técnica cirúrgica de escolha. Portanto, mais estudos são necessários para estabelecer um algoritmo específico.

Characterization of chronic pain in breast cancer survivors using the McGill Pain Questionnaire.

The aim of the present study was to characterize pain in breast cancer survivors using the McGill Pain Questionnaire (MPQ). A descriptive, cross-sectional study was conducted with 30 women aged 30-80 years who had been submitted to treatment for breast cancer (surgery and complementary treatment) at least 12 months earlier with reports of pain related to the therapeutic procedures. Pain was characterized using the full-length version of the MPQ, which is made up of 78 descriptors divided into four categories: sensory (ten items), affective (five items), evaluative (one item) and miscellaneous (four items). Two indices were also used to measure pain through the use of the descriptors: the number of words chosen (NWC) and the pain rating index (PRI). The most frequent descriptive terms were "agonizing" (n = 16; 53.3%), "tugging" (n = 15; 50%), "sore" (n = 14; 46.7%), "wretched" (n = 14; 46.7%), "troublesome" (n = 13; 43.3%) and "spreading" (n = 11; 36.7%). The sensory category had the highest PRI value based on the descriptors chosen (mean: 0.41). Women with chronic pain following treatment for breast cancer employed the "agonizing", "tugging" and "sore" descriptors with greatest frequency and rated pain in the sensory category as having the greatest impact.

Evolution of petaloidy in the zingiberales: An assessment of the relationship between ultrastructure and gene expression patterns.

BACKGROUND: The development of petal-like organs has occurred repetitively throughout angiosperm evolution. Despite homoplasy, it is possible that common underlying molecular mechanisms are repeatedly recruited to drive the development of petaloid organs. In Zingiberales, infertile, petal-like structures replace fertile stamens, resulting in petaloidy in androecial whorls. Assuming that androecial petaloidy is a shared derived characteristic, we expect to find common ultrastructure and molecular mechanisms underlying androecial petaloidy across Zingiberales. RESULTS: We show that petaloidy in Zingiberales is associated with tightly packed, protruding epidermal cells. Expression patterns for candidate genes involved in petal identity differ between the petaloid organs of Costaceae v. Cannaceae, despite similar macro- and microscopic organization. For all candidate gene families analyzed, our data suggest at least one Zingiberales-specific duplication event. CONCLUSIONS: Our data suggest that the patterns of B-class gene expression across the Zingiberales do not correlate with the occurrence of petaloidy, indicating that androecial petaloidy might have evolved independently of B-class gene expression in some lineages. It is possible that gene duplication may play a role in the diversity of petaloid structures found throughout the Zingiberales. It is likely that Zingiberales petaloidy may also result from the deployment of genes other than those involved in specification of petal identity.

Barriers for the inclusion of sexuality in nursing care for women with gynecological and breast cancer: perspective of professionals.

AIM: qualitative study, which aimed to identify the barriers that influence nursing care practices related to the sexuality of women with gynecological and breast cancer. METHODS: the study was conducted with 16 professionals of the nursing area (nurses, nursing technicians and nursing assistants) from two sectors of a university hospital situated in the state of São Paulo, Brazil. The data was collected using semi-structured, in-depth individual interviews. All the interviews were recorded and the participants' responses were identified and categorized using Content Analysis. RESULTS: three major themes were identified. These are as follows: 1) barriers related to the biomedical model; 2) barriers related to institutional dynamics and 3) barriers related to the social interpretations of sexuality. CONCLUSIONS: the results of this study showed that the systematized inclusion of this issue in nursing care routines requires changes in the health paradigm and in the work dynamic, as well as reflection on the personal values and social interpretations related to the topic. A major challenge is to divest sexuality of the taboos and prejudices which accompany it, as well as to contribute to the nursing team being more aware of the difficulties faced by women with gynaecological and breast cancer.

[Incidence and management of chemotherapy-induced nausea and vomiting in women with breast cancer]. / Ocorrência e manejo de náusea e vômito no tratamento quimioterápico em mulheres com câncer de mama.

The objective of this study was to analyze the incidence of chemotherapy-induced nausea and vomiting in women with breast cancer and identify strategies used by them to control these signs and symptoms. Data for this cross-sectional study were collected through interviews during the last cycle of chemotherapy, between August 2011 and March 2012, in a university hospital in the State of São Paulo. The sample consisted of 22 women between the ages of 31 and 70, of whom 77.3% reported nausea and 50% vomiting during treatment. Regarding symptom management, 82% of the women reported having received some information centered on the use of prescribed medication. However, 27.3% did not know what medication they had taken. We concluded that there is a lack of systematic care and institutional protocol to guide professionals in providing standardized information to women so they can better control nausea and vomiting.

Co-option of the polarity gene network shapes filament morphology in angiosperms.

The molecular genetic mechanisms underlying abaxial-adaxial polarity in plants have been studied as a property of lateral and flattened organs, such as leaves. In leaves, laminar expansion occurs as a result of balanced abaxial-adaxial gene expression. Over- or under- expression of either abaxializing or adaxializing genes inhibits laminar growth, resulting in a mutant radialized phenotype. Here, we show that co-option of the abaxial-adaxial polarity gene network plays a role in the evolution of stamen filament morphology in angiosperms. RNA-Seq data from species bearing laminar (flattened) or radial (cylindrical) filaments demonstrates that species with laminar filaments exhibit balanced expression of abaxial-adaxial (ab-ad) genes, while overexpression of a YABBY gene is found in species with radial filaments. This result suggests that unbalanced expression of ab-ad genes results in inhibition of laminar outgrowth, leading to a radially symmetric structure as found in many angiosperm filaments. We anticipate that co-option of the polarity gene network is a fundamental mechanism shaping many aspects of plant morphology during angiosperm evolution.

Neutropenia: occurrence and management in women with breast cancer receiving chemotherapy.

OBJECTIVES: to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer. METHODS: observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant. RESULTS: 79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia. CONCLUSION: neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care.

[Nausea, vomiting and quality of life in women with breast cancer receiving chemotherapy]. / Náuseas, vômitos e qualidade de vida de mulheres com câncer de mama em tratamento quimioterápico.

The aim of this study was to assess the quality of life (QoL) of women with breast cancer during chemotherapy and to identify the incidence of nausea and vomiting during the treatment Data were assessed with the application of the instrument of the European Organization for Research and Treatment of Cancer, EORTC-QLQ-C30 Portuguese version and breast cancer module BR-23, which was applied before, in the middle and in the end of the treatment. The participants were 79 women, of which 93% had nausea and 87% had vomited at least once during the treatment. QoL showed a slight decrease during treatment. Cronbach's alpha for each application of the questionnaires was 0.890492, 0.936392 and 0.937639. The availability of treatment information and guidelines on the management of nausea and vomiting is crucial for the proper management of the toxicities of chemotherapy.

Evaluation of the psychometric properties of the Functional Assessment of Cancer Therapy-Cervix questionnaire in Brazil.

BACKGROUND: Although cervical cancer is ​​the second most common tumor among Brazilian women, studies that evaluate the quality of life of these women are still scarce. This situation is explained by the lack of specific and validated tools for this purpose in Portuguese (Brazil). The aim of this study was to evaluate the psychometric properties of the Portuguese version of the FACT-CX (Functional Assessment of Cancer Therapy-Cervix) questionnaire in a population of Brazilian women with cervical cancer. METHODS: The psychometric properties of the FACT-CX questionnaire were tested in a sample of 100 women diagnosed with cervical cancer who were previously treated in the Barretos Cancer Hospital. We analyzed the internal consistency (Cronbach's alpha), reproducibility (intraclass correlation coefficient--ICC), confirmatory factor analysis, convergent validity (correlation with the SF-36 questionnaire), and discriminant validity by disease stage and two questions related to self-perception of health was also performed. RESULTS: The scales had Cronbach's alpha coefficients ranging from 0.61 to 0.80. However, three scales did not have a statistically significant coefficient greater than 0.70. The ICC ranged from 0.68 to 0.82 and all considered satisfactory. Factor analysis did not generate consistent components. The FACT-G and FACT-CX total scores had good internal consistency and reproducibility, and also correlated well with the General Health and Vitality scales of the SF-36. However, only two FACT-CX scales had a significant correlation with SF-36. Discriminant analysis showed that FACT-CX failed to discriminate groups according to clinical stage but was able to divide the women according to the self-perception of health. CONCLUSION: FATC-CX total score had good internal consistency, reproducibility and discriminant validity. In addition, it correlated well with General Health and Vitality scales of SF-36. However, three scales had questionable internal consistency and only two had significant correlation with SF-36.

The response to gender violence among Brazilian health care professionals.

The scope of this paper is to identify the experience, attitudes and impressions of health care professionals (HCPs) in addressing the needs of women patients suffering from intimate partner violence (IPV). In-depth interviews were conducted with 14 doctors and 11 nurses in Ribeirão Preto. Results show that there is an 'apparent invisibility' of IPV, the convenience of a tacit compact of silence about such violence on the part of women and HCPs. We studied the reasons given by HCPs for failing to deal with IPV. We also addressed the health service facility context, and the diversity of the professioinals' responses to violence, with indications of the emergence of a more proactive and positive stance. Qualitative data analysis highlights previous survey findings. A positive response from HCPs shows that there is perhaps some change from a narrow, medically-focused model of health care, to a more broadly defined social model.

Perception and Attitudes of Physicians and Nurses about Violence against Women.

Cross-sectional study compares the perception and attitudes about violence against women of physicians and nurses working in the primary health care clinics in Ribeirão Preto, SP. A total of 170 physicians and 51 nurses were interviewed in the District Health Clinics. Physicians feel more comfortable than nurses to talk about the sex life of patients (P = 0.048) and to investigate the use of drugs (0.001). Compared to the nurses greater number of physicians believed that the aggression to the woman by the husband should be treated as a medical problem (P = 0.000). Both believe that external factors, as alcohol or drug abuse, unemployment, and psychological problems of the husband and not of the victim, can cause violent acts. Most interviewees understand that gender violence exceeds the issues of individuality and privacy and has become a public health problem, by the dimension present in the social relationships.

Prevention of skin reactions due to teletherapy in women with breast cancer: a comprehensive review.

One of the possible courses of cancer treatment is teletherapy, and one of the most important adverse side effects are skin reactions, an ailment more commonly called radiodermatitis. The main purpose of this study is to analyze knowledge of the evidence about topical products used in the prevention of radiodermatitis, to support care delivery to women with breast cancer during teletherapy. The research method used here is the comprehensive literature review. Four databases were used to select the bibliography. The sample consists of 15 articles. The data shows that, among the topical products analyzed here, Calendula, corticosteroids and Xclair have shown significant protective effects, underlining their actions. The lack of articles published in Brazil highlights the need for further research in this area, seeking better care quality through the use of products with scientifically proven efficiency.

Childbirth experience according to a group of Brazilian primiparas.

OBJECTIVE: to understand the meaning of the childbirth experience for Brazilian primiparas in the postpartum period. DESIGN: a qualitative approach using semi-structured interviews. Content analysis was used to derive the two themes that emerged from the discourses. SETTING: participants were recruited at four primary-level health-care units in Ribeirão Preto, Brazil. After providing written informed consent, an appointment was made for an interview at the participants' homes. PARTICIPANTS: 20 primiparas in the postpartum period, aged 15-26 years old, who attended the health-care units to vaccinate their infants and test for phenylketonuria. FINDINGS: two thematic categories emerged from the interviews: the meaning attributed to childbirth (with four subcategories) and perceptions of care. Among the participants, the childbirth experience was marked by the 'fear of death' and 'losing the child'. The pain of giving birth was expected, and the moment of childbirth was associated with pain of high intensity. KEY CONCLUSIONS: childbirth is considered synonymous with physical and emotional suffering, pain, fear and risk of death. IMPLICATIONS FOR PRACTICE: this research indicates the need to break the current mechanistic model of care on which health professionals' actions are based. Care during childbirth must be guided by the foundation that women are the subjects of childbirth actions, in an attempt to emphasise actions that grant them with the autonomy and empowerment needed to experience the situation.
