Tumor necrosis factor inhibitors contribute to a greater susceptibility to infection or reactivation of Mycobacterium tuberculosis. Endobronchial tuberculosis has non-specific symptoms, which may delay the diagnosis. We report a case of a 21-year-old woman, with Crohn’s disease, medicated with adalimumab. The patient presented with a 2-week history of fever, dry cough, pleuritic chest pain and weight loss of 2 kg. Chest imaging showed bilateral nodular opacities, at the right pulmonary apex. Bronchoscopy revealed a tumorous lesion in the right upper bronchus. Bronchial biopsies were suggestive of chronic granulomatous inflammation. Bronchoalveolar lavage produced a positive for acid-fast bacilli smear and culture for Mycobacterium tuberculosis. We assumed the diagnosis of tuberculosis with endobronchial manifestations. Nowadays this is a rare manifestation. Empirical treatment for tuberculosis was initiated, with steroids as an adjunct therapy to prevent bronchostenosis, with clinical and radiological improvement.

Discharge of whey proteins is still a current practice by small cheese producers. The development of low-cost alternatives for recovery of these proteins is fundamental for small producers who cannot apply expensive techniques. The present study investigated the complex coacervation technique as a cheap technology to recover proteins from sweet whey using carboxymethylcellulose, and the coacervate used as an ingredient in the formulation of probiotic fermented milk. The nutritional properties of whey-carboxymethylcellulose coacervates (WP-CMC) were evaluated in trials with animals (rats) using casein as a reference. All these parameters—the coefficient of feed efficiency (CEA), protein digestibility-corrected amino acid score (PDCAAS), and net protein ratio (NPR), as well as weight gain—were determined to evaluate protein quality. A sensory acceptance test was applied to evaluate the sensory characteristics of the product. The complex coacervation technique recovered 86% of the protein from sweet whey. No significant (p > 0.05) differences were observed in the biological tests for both groups (WP-CMC and Casein groups) when NPR (4.98 to 5.04), digestibility (92.35 to 90.64), and CEA (0.40 to 0.42) were evaluated. Probiotic fermented milk beverage containing WP-CMC (0.78%) and guar gum (0.68%) presented good acceptability as determined by sensory evaluation. WP-CMC can be considered an ingredient with high nutritional and biological value that could be applied in probiotic fermented milk as an alternative to small producers to allocate the residual whey from cheese manufacture.

Objective: This study aimed to measure the serum concentrations of several cytokines in patients with infective endocarditis (IE), and correlate them with the C-reactive protein serum levels, echocardiographic findings and infecting microorganisms. Methods: Forty-five patients with definite IE according to the Duke’s criteria were included in the study. Ten healthy blood donors formed the control group. Serum levels of interleukin (IL) 1β, IL-6, IL-8, IL-10, IL-12 and tumor necrosis factor-α (TNF-α) were measured and compared between the groups, and also with some clinical and laboratory parameters of IE. Results: Patients with IE had significantly higher serum concentrations of the inflammatory mediators than the control patients. Median IL-12 and IL-1β levels were higher in staphylococcal than streptococcal IE. Except for TNF-α, the levels of all the other cytokines correlated with the C-reactive protein concentrations. In multivariate analysis, IL-10 and IL-12 serum levels remained as independent factors associated with the C-reactive protein concentrations. There was a significant correlation between IL-10 concentration and vegetation length. Conclusion: The inflammatory serum cytokines levels were elevated in IE in comparison to healthy controls. C-reactive protein concentrations correlated with cytokines levels. IL-1β and IL-12 serum concentrations were higher in staphylococcal when compared to streptococcal IE. IL-10 levels were associated with vegetation size.

Background: For the WHO, anemia is a serious public health problem, with an emphasis on deprivation anemia, which has socioeconomic conditions as determining factors for its development. Among nutritional anemias, the most relevant is iron deficiency, whose main form of prevention and treatment is supplementation with ferrous sulfate dispensed in the public health system, with the need to periodically check whether the drug has the quality required by regulatory health agencies. Thus, the objective of this study was to analyze the quality of the ferrous sulfate medication, from the same laboratory, and dispensed in a basic health unit (BHU) and a commercial pharmacy (CF). Materials and Methods: An analytical, qualitative and quantitative study of ferrous sulfate heptahydrate (25 mg/mL in 100 mL syrup), carried out on 20 BHU and 10 from CF, both from the same laboratory, but in different batches. Samples were subjected to organoleptic analysis and verification of iron content, pH, volume and density. Data were compared with values recommended by the Brazilian pharmacopoeia 5th edition. Results: Three batches were evaluated: 4659 of from the CF;4574 from the BHU1, and 4576 from the BHU2, stored in accordance with RDC 304/19 of ANVISA. All showed compliance with some organoleptic characteristics;and stable values in pH (3.61 - CF;3.67 - BHU1;3.65 - BHU2), density (1.079 - CF;1.088 - BHU1;1.086 - BHU2) and individual volume (not less than 95% of the declared value). However, it was not possible to detect the odor of herbs;the average volume of batch BHU1 was below the declared value, and the iron content of both BHUs was above the maximum value of pharmacopoeia standards. Conclusion: Samples did not show full compliance with the physical and chemical parameters evaluated, suggesting deviation in the quality of the medication.
