Três vidas que se desvelam no Sertão : uma análise de Fabiano, Francisca e Riobaldo com o meio no qual se inserem
Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Instituto de Letras, Departamento de Linguística, Línguas Clássicas e Português, 2020.Este trabalho pretende observar e analisar os personagens Fabiano, de Vidas secas, Francisca, de Dora sem véu, e Riobaldo, de Grande sertão: veredas, sob a perspectiva de como esses se relacionam com o meio no qual estão inseridos nos romances: o sertão. Os personagens, bem diversos entre si, relacionam-se de forma diferente com esse território. Por conta de diferenças na integração desses com o cenário urbano e pelas discrepâncias no nível da educação formal existentes entre Fabiano, Francisca e Riobaldo, as formas como eles leem e interpretam o mundo que os cercam também se distanciam bastante de um para o outro. Isso expande a percepção criada a respeito do sertão literário, levando em consideração a ótica dos personagens, que ganham protagonismo sobre a terra. Nesse sentido, a relação desses tipos com o sertão é o cerne desta análise, a se destacar a influência que a instrução exerce nessas relações
Billroth I Technique Application After Resection of Gastric Leiomyoma in a Dog
Background: Gastric neoplasia is rare, corresponding to less than 1% of cases, with a lower prevalence of those involving smooth muscle tissues. In these cases, clinical signs worsen in the occurrence of pyloric obstruction, leading to clinical manifestations such as chronic emesis. The exeresis of the neoplasm is promoted as a therapeutic measure to reestablish gastrointestinal flow. There partial gastrectomy followed by gastroduodenal anastomosis, using the Billroth I technique, is among the available surgical techniques. The therapeutic success of the Billroth I technique after pylorectomy was reported in a dog with gastric leiomyoma.Case: Canine, poodle, 9 years old, 9.5 kg, with a history of chronic vomiting starting three months ago, progressive weight loss, and melena, previously treated by another Veterinarian as idiopathic gastroenteritis. The physical evaluation of the animal showed a state of normal consciousness, body score 4/9, pale ocular and oral mucous membranes, respiratory rate 20 mpm, heart rate 166 bpm, a rectal temperature of 37.9 °C, and dehydration degree of 8.0%. Blood count showed normocytic normochromic anemia and leukocytosis with shift to the right. Radiographic and endoscopic examinations were not noteworthy. Endoscopic biopsy after a histopathological evaluation showed no cellular or tissue atypia. On the other hand, abdominal ultrasound assessment revealed thickening with loss of echotexture and definition of the muscular layer of the gastric wall, pyloric and duodenum region compatible with benign antral muscle hypertrophy and/or pyloric neoplasia. The animal worsened five days after the initial treatment, with progressive episodes of emesis and melena, opting for an exploratory laparotomy. A mass of firm consistency measuring approximately 2.5 × 6.0 cm in diameter was found in the pyloric region, opting for a pylorectomy. The excised fragment was sent for histopathological examination. Then, gastroduodenal anastomosis was performed using the Billroth I technique. After the surgery, a pasty diet was introduced orally, without using gastroenteric tubes. Dry food was offered ten days after the surgical procedure. The animal returned for clinical reevaluation on the fifteenth day and was clinically well. Histopathological examination revealed a diagnosis of gastric leiomyoma.Discussion: The casuistry of gastric neoplasia in dogs has a low incidence, with an occurrence of less than 1%, with adenocarcinoma being the most common type. However, there are less frequent reports of other gastric neoplasia, such as smooth muscle tumors. Abdominal ultrasonography is indicated for the diagnosis of gastrointestinal changes, proof of which ultrasonography was of paramount importance in this case. The surgical procedure of pylorectomy guaranteed a margin of one centimeter, meeting the principles of oncological surgery. Absorbable monofilament suture materials are the choice for the synthesis stage in hollow organs, being used in this case. The most-reported expected complications of gastrointestinal surgeries aiming at removing neoplasms are vomiting, anorexia, melena, hematochezia, hematemesis, necrosis with anastomotic ulceration, and, consequently, septic peritonitis, which were not reported in this case. The life expectancy of patients with gastric neoplasia is quite variable, with longer survival in cases of benign neoplasia. Therefore, the type of neoplasia in this case, together with the appropriate choice of therapy and the appropriate performance of the technique, was important for the good result achieved
The complete genome sequence of Chromobacterium violaceum reveals remarkable and exploitable bacterial adaptability
Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications
Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults
Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We
estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from
1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories.
Methods We used data from 3663 population-based studies with 222 million participants that measured height and
weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate
trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children
and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the
individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference)
and obesity (BMI >2 SD above the median).
Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in
11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed
changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and
140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of
underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and
countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior
probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse
was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of
thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a
posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%)
with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and
obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for
both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such
as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged
children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls
in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and
42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents,
the increases in double burden were driven by increases in obesity, and decreases in double burden by declining
underweight or thinness.
Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an
increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy
nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of
underweight while curbing and reversing the increase in obesit
Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Tratamento de mamas tuberosas com incisões combinadas Treatment of tuberous breast with combined incisions
INTRODUÇÃO: A deformidade tuberosa da mama é uma rara entidade, descrita por Rees e Aston em 1976. O desenvolvimento mamário encontra-se alterado, com herniação do parênquima pelo complexo areolopapilar, alargamento dessa estrutura e hipoplasia do tecido mamário, principalmente nos quadrantes inferiores. A mama, portanto, adquire um aspecto tubular ao invés do aspecto cônico natural. MÉTODO: No total, 4 pacientes foram submetidas a tratamento cirúrgico em um único tempo, com incisões combinadas: inframamária e periareolar. Detalhes técnicos devem ser individualizados para cada caso, conforme a gravidade e a classificação do tipo de mama tuberosa. RESULTADOS: O procedimento cirúrgico utilizado aborda todos os aspectos da deformidade da mama tuberosa em operação de um estágio. Cirurgia de revisão de cicatriz periareolar não foi necessária em nenhum caso. Em todos os casos, obteve-se resultado estético final aceitável e com satisfação da paciente e do cirurgião. O procedimento adotado não interfere em lactações futuras. CONCLUSÕES: A mama tuberosa representa um verdadeiro desafio terapêutico. A técnica utilizada é muito atraente e mostra resultados confiáveis e reprodutíveis.BACKGROUND: Tuberous breast deformity is a rare entity, first described by Rees and Aston in 1976. In this condition, breast development is altered, with herniation of the parenchyma through the nipple-areolar complex, enlargement of this structure, and hypoplasia of the breast tissue, especially in the lower quadrants. The breast thus acquires a tubular shape rather than the natural conical look. METHODS: Four patients underwent a single surgical treatment, with combined inframammary and periareolar incisions. Technical details must be individualized for each case depending on the severity and classification type of the tuberous breasts. RESULTS: The surgical procedure used covers all aspects of tuberous breast deformity in a single-stage operation. Revision of periareolar surgery scar was not necessary in any case. In all cases, the final aesthetic result was satisfactory for the patient and the surgeon. The procedure adopted does not interfere with future lactation. CONCLUSIONS: Tuberous breast represents a real therapeutic challenge. The technique reported herein is very attractive and provides reliable and reproducible results

Diminishing benefits of urban living for children and adolescents’ growth and development
Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified
