Consumption of processed and ultra-processed foods by patients with stomach adenocarcinoma: a multicentric case-control study in the Amazon and southeast regions of Brazil.

PURPOSE: There is limited information about the dietary habits associated with stomach adenocarcinoma in the Brazilian population, so our purpose is to analyze the consumption of processed and ultra-processed foods by patients with stomach adenocarcinoma in Brazil. METHODS: A multicentric hospital-based case-control study was conducted in São Paulo (southeastern region) and Belém (Amazon region) of Brazil with 1,045 individuals, both sexes, between 18 and 75 years old. In São Paulo, there were 214 cases with stomach adenocarcinoma and 150 controls patients submitted to stomach endoscopy named as Group I (without any pre-malignant gastric disease) and the Healthy Controls (Group 2) comprised 401 individuals matched by age and sex from the prevention unit at A.C .Camargo Cancer Center. In Belém, it has two groups one are cases 140 and second 140 hospital controls, recruited in outpatient clinics. Lifestyle and food frequency questionnaires (FFQ) were administered in cases and controls in both places. Univariate and multivariable binomial logistic regression analyses were performed. RESULTS: In São Paulo, cases reported two times greater consumption of processed meat (adjusted OR 2.56, 95% CI 1.32-4.96) and of sweets (≥ 80 g/day) than Group 1 (endoscopic controls) (adjusted OR 2.25, 95% CI 1.21-4.18). Compared with Group 2, processed food consumption (≥ 44 g/day) as well as ≥ 44 g/day of salted bread increased the odds of having stomach adenocarcinoma (adjusted OR 2.96, 95% CI 1.82-4.81 and adjusted OR 2.03, 95% CI 1.30-3.18), respectively. In Belém, individuals who reported consuming ≥ 166 g/day of fried and roasted meat and fish were more likely to have stomach adenocarcinoma (adjusted OR 2.21, 95% CI 1.13-4.30). CONCLUSIONS: In both cities, consumption of processed and ultra-processed foods, especially salted bread, yellow cheese, fried and roasted meats, fish fried, processed meat, and sweets, was independently associated with the chance of having stomach adenocarcinoma.

Offspring of mothers with bipolar disorder: a systematic review considering personality features.

OBJECTIVE: To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures. METHODS: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, was conducted to search for original articles that investigated personality/temperament features of offspring of women with BD and emotional factors involved in the mother-child relationship. The electronic search was performed in the PubMed, Web of Science, and PsycINFO databases from February 2010 to February 2017. RESULTS: Ten quantitative studies were included in the analysis: seven from the United States, two from Brazil, and one from Canada. The narrative synthesis was categorized into three dimensions: 1) reliability of instruments for prediction of future psychopathology in offspring; 2) environmental risk factors for offspring; and 3) early interventions. The findings showed impairments in the offspring's lives, high rates of behavior and temperament problems, and psychiatric disorders. CONCLUSION: BD is a frequent psychiatric disorder, and the offspring of mothers with this condition are exposed to complex family relationships and psychosocial difficulties. If they are to ensure a good provision of mental health and psychosocial care to this unique population, early interventions must not neglect their contextual specificities. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD-42017039010.

Bioactive molecule optimized for biofilm reduction related to childhood caries.

Aim: To evaluate antimicrobial activity of a new nitrochalcone (NC-E08) against Candida albicans and Streptococcus mutans, and its toxicity. Materials & methods: Minimum inhibitory concentration (MIC) and minimum bactericidal concentration/minimum fungicidal concentration (MFC) were determined against C. albicans and S. mutans, as well as antibiofilm potential and toxicity (human gingival fibroblast and Galleria mellonella). Infection and treatment were performed in G. mellonella. Results & conclusion: NC-E08 showed antimicrobial activity in C. albicans (MIC: 0.054 mM) and S. mutans (MIC: 0.013 mM); 10xMIC treatment reduced 4.0 log10 biofilms for both strains and there was a reduction in survival of mixed biofilms of C. albicans and S. mutans (6.0 and 4.0 log10, respectively). NC-E08 showed no cytotoxicity in human gingival fibroblast cells and G. mellonella. NC-E08 after larval infection protected them 90% (p < 0.05). Thus, is a promising one for the prevention and treatment of S. mutans and C. albicans infections.

Nail Unit Glomus Tumor with Myxoid and Symplastic Change Presenting with Longitudinal Erythronychia.

Glomus tumors are soft tissue neoplasms, which are most frequently encountered in the nail unit and generally straightforward to diagnose by histopathology. The typical clinical presentation is that of a circular violaceous or erythematous lesion within the nail bed. However, there are rare variants of glomus tumors which may pose diagnostic challenges because of the presence of unusual histologic features. Herein we report such a glomus tumor that demonstrates the rare combination of both myxoid and symplastic change. The clinical presentation of longitudinal erythronychia, as seen with this case, can occur with glomus tumors, but it is unusual, as longitudinal erythronychia on a single nail usually is caused by an onychopapilloma. The distinct nuclear atypia characteristic of symplastic change can raise alarm for a malignant process but the clinical course is benign. It is essential for dermatopathologists to be aware of this unusual variant of a glomus tumor in order to avoid overdiagnosis of atypia, which could result in unnecessary aggressive surgery. While unusual, there is good clinicopathologic correlation of the glomus tumor presenting with longitudinal erythronychia.

Epidemiology of multiple myeloma in 17 Latin American countries: an update.

The objective of this study was to describe incidence, mortality rates, and trends for multiple myeloma (MM) in Latin America (LA), contributing to better knowledge on the epidemiology of MM in this continent. Incidence data were extracted from the International Agency for Research on Cancer (IARC), for the period 1990-2007. Mortality data were obtained for 17 countries from the World Health Organization, for the period 1995-2013. Annual average percentage change (AAPC) and 95% confidence interval (95% CI) were calculated for incidence and mortality. The average incidence rate of MM was higher in Cali (Colombia). For the age-group over 60 years old, rates were 14.2 and 12.8 per 100,000 inhabitants for men and women, respectively. Increasing incidence trends were verified for Cali (Colombia). Mortality rates were higher among men; most countries presented increasing trends, and the highest increments were observed in Guatemala (12.5% [95% CI: 10.6; 14.5] in men; 8.8% [95% CI: 7.8; 9.8] in women), Ecuador (5.5% [95% CI: 5.0; 6.0] in men; 3.7 [95% CI: 3.1; 4.3] in women), Paraguay (2.9% [95% CI: 2.3; 3.5] in men; 3.2% [95% CI: 2.1; 4.3] in women), and Brazil (1.4% [95% CI: 1.3; 1.5] in men; 0.9% [95% CI: 0.8; 1.0] in women). Multiple myeloma presented heterogeneous incidence patterns in Cali (Colombia), Quito (Ecuador), and Costa Rica. Increasing mortality trends were verified for most Latin American countries and could be related to limited access to diagnosis and new therapies.

Intoxicação natural por Senecio brasiliensis em equinos / Natural poisoning by Senecio brasiliensis in horses

Intoxicações por plantas do gênero Senecio representam uma importante causa de morte em animais de produção, sendo Senecio brasiliensis a espécie mais envolvida nos casos de intoxicação espontânea. Nesse trabalho, são descritos os aspectos epidemiológicos, clínicos e anatomopatológicos de um surto de intoxicação natural por Senecio brasiliensis em equinos. Dois equinos, de um total de dezoito, foram afetados. Os casos ocorreram em uma propriedade rural no município de São Martinho da Serra, Rio Grande do Sul, Brasil. Grande quantidade de exemplares de Senecio brasiliensis em estágio de brotação foi encontrada na área onde os equinos estavam. Os animais eram da raça Crioula, sendo uma égua com quatro anos e um potro com cinco meses. A égua apresentou evolução aguda da doença com duração de três dias e o potro evolução crônica de dois meses. As principais manifestações clínicas observadas em ambos os equinos incluíam apatia, anorexia, emagrecimento, desidratação e sinais neurológicos. Além disso, havia moderado edema subcutâneo na região ventral do abdômen e marcada icterícia nas mucosas ocular, oral e vulvar da égua e palidez das mucosas no potro. Na avaliação bioquímica do potro, havia acentuado aumento da atividade sérica da gamaglutamil transferase (119 U/L), aumento da fosfatase alcalina (434 U/L) e hipoalbuminemia (2,1g/dL). No hemograma do mesmo, observou-se leve anemia normocítica e normocrômica (30% de hematócrito; VCM: 39,5 fL; HCM: 15,3pg). As alterações presentes em ambas as necropsias foram observadas principalmente no fígado, que estava difusamente aumentado de tamanho, escuro e firme. Na superfície de corte, observaram-se acentuação do padrão lobular e hemorragia. Histologicamente, no fígado dos equinos, havia graus variados de necrose coagulativa, hemorragia, fibrose, proliferação de ductos biliares, hepatomegalocitose e bilestase. Nas diferentes seções analisadas do encéfalo, havia alterações astrocitárias restritas à substância cinzenta, predominantemente, no córtex telencefálico. Os astrócitos degenerados eram similares aos astrócitos de Alzheimer tipo II. O diagnóstico da intoxicação nesses casos foi baseado na epidemiologia, no quadro clínico, nas lesões de necropsia e nos achados histopatológicos. Cabe ressaltar que a necrose de coagulação e a discreta fibrose e proliferação de ductos biliares observados na égua, constituiu uma apresentação subaguda da intoxicação, enquanto que a fibrose, mais predominante no potro, caracterizou uma hepatopatia crônica.(AU)

Poisoning due to plants of the genus Senecio is considered an important cause of death in livestock. Senecio brasiliensis is the most common species involved in spontaneous cases. This paper describes the epidemiological, clinical and pathological aspects of a natural outbreak of intoxication with Senecio brasiliensis affecting two out of eighteen horses in a farm. The cases occurred in the municipality of Sao Martinho da Serra, Rio Grande do Sul State, Southern Brazil. A large amount of Senecio brasiliensis in its sprouting stage was found in the fields where the horses used to be kept. A four-year-old, Crioulo mare and a five-month-old, male, Crioulo foal were affected. The clinical course was acute in the mare, comprising three days and chronic in the foal, lasting for two months. The main clinical signs in both animals included apathy, anorexia, weight loss, dehydration and neurological signs. Moreover, subcutaneous edema was noted in the ventral abdomen and the mucous membranes were icteric in the mare and pale in the foal. The serum biochemistry in the foal showed hypoalbuminemia (2.1g/dL), increased activity of the serum alkaline phosphatase (434 U/L) and gamma glutamyl transferase (119 U/L). In the hemogram, a mild normocytic normochromic anemia was noted in the foal (Hct: 30%; MCV: 39.5 fL; MCH: 15.3pg). Necropsy findings observed in both horses included an enlarged, dark red and firm liver with extensive areas of hemorrhage and enhanced lobular pattern on cut surface. Histologically, the liver showed variable degrees of fibrosis, coagulative necrosis, biliary ducts hyperplasia, megalocytosis and cholestasis. In the brain, the astrocytes in the cerebrum were degenerated and similar to Alzheimer type II astrocytes. The diagnosis in this outbreak was established based on the epidemiology, clinical picture, gross and histologic findings. It is noteworthy that the coagulative necrosis, minimal fibrosis, and biliary duct hyperplasia observed in the mare are characteristic of a subacute presentation. On the other hand, the fibrosis that was more prominent in the foal characterizes a chronic hepatopathy.(AU)
