    Abstract Recently, fruit by-products (FBP) have started to be explored due to their prebiotic potential associated with considerable amounts of dietary fibers and polyphenols. These compounds possess anti-inflammatory activity and can reduce dysbiosis, which is characterized by alterations in the composition and function of the gut microbiota and thus may reduce the onset or progression of several diseases. Therefore, the consumption of FBP must be encouraged. Among food products, fermented milk is a potential candidate for carrying FBP. In this scenario, this review discusses the prebiotic potential of FBP and their anti-inflammatory activity and brings a unique contribution, as it highlights fermented milk as a food carrier for FBP. Therefore, the technological application of FBP as a new ingredient to improve the nutritional and functional values of fermented milk, probiotic viability, and the effects of their addition on the physical and sensory characteristics of fermented milk are topics extensively covered in this review. Moreover, we described the chemical composition of FBP, focusing on polysaccharides and bioactive compounds, their obtention methods and potential adverse effects related to their consumption. Finally, limitations and future directions are outlined to deepen the understanding of FBP and to stimulate their use, to prove their prebiotic potential and to optimize their incorporation into fermented milk.

    Abstract Coenzyme Q (CoQ) is essential for mitochondrial respiration and required for thermogenic activity in brown adipose tissues (BAT). CoQ deficiency leads to a wide range of pathological manifestations, but mechanistic consequences of CoQ deficiency in specific tissues, such as BAT, remain poorly understood. Here, we show that pharmacological or genetic CoQ deficiency in BAT leads to stress signals causing accumulation of cytosolic mitochondrial RNAs and activation of the eIF2α kinase PKR, resulting in activation of the integrated stress response (ISR) with suppression of UCP1 but induction of FGF21 expression. Strikingly, despite diminished UCP1 levels, BAT CoQ deficiency displays increased whole-body metabolic rates at room temperature and thermoneutrality resulting in decreased weight gain on high-fat diets (HFD). In line with enhanced metabolic rates, BAT and inguinal white adipose tissue (iWAT) interorgan crosstalk caused increased browning of iWAT in BAT-specific CoQ deficient animals. This mitohormesis-like effect depends on the ATF4-FGF21 axis and BAT-secreted FGF21, revealing an unexpected role for CoQ in the modulation of whole-body energy expenditure with wide-ranging implications for primary and secondary CoQ deficiencies.

    Abstract The purpose of the present study was to perform a systematic review focusing on oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMD) in Fanconi anemia (FA) individuals. Electronic searches were undertaken in five databases supplemented by manual scrutiny and gray literature. Case reports and/or cases series were included. The searches yielded 55 studies describing 112 cases of OSCC (n = 107) and/or OPMD (n = 5) in FA individuals. The mean age at diagnosis of OSCC/OPMD was 27.1 (±9.6) years, and females (51.8 %) were slightly more affected. Ulcer (n = 37) or mass (n = 25) were described as clinical presentations for OSCC and OPMD. White lesions (n = 4) were the most common manifestation in OPMD. Tongue (47.2 %) was the most frequent location. Sixty-one (54.5 %) individuals underwent HSCT. Surgical resection (n = 75) was the main treatment adopted. The estimated rate of OPMD malignant transformation was 1.8 % and recurrences following OSCC excision occurred in 26.8 % of individuals. Overall, at 60 months of follow-up, the probability of survival fell to 25.5 % and at 64 months the probability of recurrence increased to 63.2 %. The present data support the need for strict surveillance of patients with FA, even in the absence of OPMD, for early OSCC detection and reduction of mortality.

    Abstract The search for knowledge related to the Pitaya (Hylocereus polyrhizus [F.A.C. Weber] Britton & Rose, family Cactaceae) is commonly due to its beneficial health properties e aesthetic values. But process to obtain pitaya pulp is a first and important step in providing information for the subsequent use of this fruit as colorant, for example. Therefore, the effects of the pulping process on the metabolomic and chemometric profile of non-volatile compounds of pitaya were assessed for the first time.

    Abstract Introduction: Admission to university influences lifestyle behaviors and is marked by a daily routine of accumulation of activities that can interfere with sleep duration, affecting food choices and meal consumption habits throughout the day.
    Objective: To analyze the association between short sleep duration and skipping main meals among university students.
    Materials and Methods: We conducted a cross-sectional study with 1,608 university students aged between 16 and 25 years, who were enrolled in full-time undergraduate courses at a public university in the Midwestern region of Brazil. Information on skipping breakfast, lunch, and dinner was collected through the question “On average, how often do you eat the following meals?”. Given the lack of a uniform criterion to define “skipping a meal”, in the present study, any answer that did not correspond to the daily consumption of the meal was classified as meal skipping, based on the recommendation of the Dietary Guidelines for the Brazilian Population. Short sleep duration was determined according to sleep time during the night (≤ 6 hours for those aged ≥18 years and ≤ 7 hours for those under 18 years of age). Associations were estimated using adjusted Poisson regression models.
    Results: The prevalences of skipping breakfast, lunch, and dinner were of 51.0%, 13.9%, and 35.6% respectively. Short sleep duration was observed in 27.2% of the study population. After adjusting for confounding variables, short sleep duration was positively associated with skipping breakfast (adjusted prevalence ratio [PRadj] = 1.20; 95% confidence interval [95%CI] = 1.08–1.34) and skipping lunch (PRadj = 1.64; 95%CI = 1.27–2.12).
    Conclusion: University students presented a high prevalence of skipping main meals. Short sleep duration was directly associated with skipping two major meals of the day: breakfast and lunch.

    Abstract ABSTRACT: Information on the effects of prescribed burning in forest areas is essential for numerous environmental and forest production applications, including preventive maintenance against forest fires. In this article, we evaluated the effects generated at different interfaces (borders) of a homogeneous area of eucalyptus, after the occurrence of prescribed burns. The litter recovery and the regeneration of herbaceous material were evaluated, which may compose the combustible material for the occurrence of new fires. The forest inventory include measurements of circumference at breast height (CBH), commercial and total height, canopy density percentage, and number alive and dead trees. The percentage of herbaceous plants and litterfall differentiation were determined through photos taken in the field and subjected to pixel analysis in the Adobe Photoshop Cs6 program. The litterfall was classified into leaves, barks, and branches, and the herbaceous plants was subjected to identification and quantification of phytosociological variables. The prescribed fire did not affect the survival and development of trees, since the values were consistent with the community age. Leaves represented the highest litterfall fraction (47.69%) and thick branches the lowest (1.79%), both in the eucalyptus/agriculture interface. The herbaceous plants totalized 120 individuals, with predominance of grass species and had higher abundance in the eucalyptus/agriculture and eucalyptus/forest interfaces.

    Abstract ABSTRACT We describe a patient with tertiary hyperparathyroidism with history of three episodes of deep vein thrombosis and on rivaroxaban. The patient underwent a subtotal parathyroidectomy, developing cervical hematoma with airway compression. Therefore, emergency surgical decompression was necessary. Later, on the ninth postoperative day, the serum ionized calcium levels were low. Medical team knowledge about preexisting diseases and their implication in the coagulation state are essential conditions to reduce morbidity and mortality of surgeries. However, no reports were found in literature about the association of hypocalcemia with the use of the new class of anticoagulants, which act as factor X inhibitors (Stuart-Prower factor), predisposing to increased bleeding in the immediate postoperative period.

    Abstract While chemotherapy treatment can be lifesaving, it also has adverse effects that negatively impact the quality of life. To investigate the effects of doxorubicin chemotherapy on body weight loss, strength and muscle mass loss, and physical function impairments, all key markers of cachexia, sarcopenia, and frailty. Seventeen C57/BL/6 mice were allocated into groups. 1) Control (n = 7): mice were exposed to intraperitoneal (i.p.) injections of saline solution. 2) Dox (n = 10): mice were exposed to doxorubicin chemotherapy cycles (total dose of 18 mg/kg divided over 15 days). The body weight loss and decreased food intake were monitored to assess cachexia. To assess sarcopenia, we measured muscle strength loss using a traction method and evaluated muscle atrophy through histology of the gastrocnemius muscle. To evaluate physical function impairments and assess frailty, we employed the open field test to measure exploratory capacity. Doxorubicin administration led to the development of cachexia, as evidenced by a significant body weight loss (13%) and a substantial decrease in food intake (34%) over a 15-day period. Furthermore, 90% of the mice treated with doxorubicin exhibited sarcopenia, characterized by a 20% reduction in traction strength (p<0,05), a 10% decrease in muscle mass, and a 33% reduction in locomotor activity. Importantly, all mice subjected to doxorubicin treatment were considered frail based on the evaluation of their overall condition and functional impairments. The proposed model holds significant characteristics of human chemotherapy treatment and can be useful to understand the intricate relationship between chemotherapy, cachexia, sarcopenia, and frailty.
