Can dietary fiber improve the technological characteristics and sensory acceptance of low-fat Italian type salami?

To meet the needs of new consumers, meat researchers need to develop healthier products. Dietary fibers can be added for structural purposes, to present functional characteristics or to change the composition of the final product. In this study, mixture design was used to investigate the effects of partial substitution of pork fat by inulin, fructooligosaccharides and α-cyclodextrin on the technological and sensory quality characteristics of low-fat Italian type salami. The partial substitution of fat using dietary fibers shows no effect on weight loss, Aw and pH during ripening time. However, the addition of up to 2% α-cyclodextrin increased lightness and reduced redness and yellowness. Up to 2% of inulin or fructooligosaccharides added improved the sensory acceptance, texture parameters and redness. Healthier low-fat Italian type salami can be produced using inulin or fructooligosaccharides as fat substitute for pork fat and still obtain good technological and sensorial results.

Exogenous progestogen does not affect first-wave follicle populations and oocyte quality during ovarian stimulation with FSH in sheep.

The effect of short-term administration of medroxyprogesterone acetate (MPA) or natural progesterone (P4) during ovarian stimulation with FSH on oocyte recovery was investigated in Santa Inês ewes. Ewes were treated with an intravaginal sponge containing MPA for 6 d; GnRH was applied 36 h after sponge removal and FSH was given in 3 injections (40, 24, and 16 mg, respectively) every 12 h after (D0, approximate ovulation time). At the first FSH dose, the ewes received either a new MPA sponge (n = 10) or a controlled device for internal release impregnated with P4 (n = 10) or did not receive any device (n = 10). Ovarian dynamics were assessed every 12 h by transrectal ultrasonography from D-3 to D2. Oocytes were recovered by laparoscopic ovum pick-up (LOPU) on D2 and graded by morphologic quality. The number of small, medium, and large follicles at D0 and D2 (ultrasound examinations), number of both follicles aspirated and oocytes recovered at LOPU, recovery rate, and oocyte grade did not differ (P > 0.05) among treatments. Thus, the short-term use of MPA or P4 during ovarian stimulation did not affect the first-wave follicle population or morphologic quality of oocytes. We would suggest that, in this protocol, the use of exogenous progestin is unnecessary.

Alpha-cyclodextrin as a new functional ingredient in low-fat chicken frankfurter.

1. The current consumer preference for healthier meat products is associated with less additives in manufacturing (so-called 'clean-label') or the addition of non-meat ingredients with functional properties, recognised as improving specific technological properties in meat products.2. This study evaluated the effect of the addition of alpha-cyclodextrin and wheat fibre to low-fat chicken frankfurters containing 35% mechanically deboned chicken meat on the technological and sensorial properties during refrigerated storage.3. The results showed that the addition of dietary fibres (alpha-cyclodextrin and wheat fibre) in low-fat chicken frankfurters improved emulsion stability, hardness, chewiness and reduced cohesiveness.4. Alpha-cyclodextrin helped the retention of fat globules in the microstructure and affected colour in the sensorial evaluation.5. The use of alpha-cyclodextrin, in combination with wheat fibre, as a new ingredient to substitute fat in emulsified meat products containing mechanically deboned chicken, improved emulsion stability and texture.6. Alpha-cyclodextrin and wheat fibre were effective in contributing to fat reduction without affecting the sensory properties of the product.

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background Complex percutaneous coronary intervention (PCI) is associated with higher ischemic risk, which can be mitigated by long-term dual antiplatelet therapy (DAPT). However, concomitant high bleeding risk (HBR) may be present, making it unclear whether short- or long-term DAPT should be prioritized. Objectives This study investigated the effects of ischemic (by PCI complexity) and bleeding (by PRECISE-DAPT [PRE dicting bleeding Complications in patients undergoing stent Implantation and Sub sequent Dual Anti Platelet Therapy] score) risks on clinical outcomes and on the impact of DAPT duration after coronary stenting. Methods Complex PCI was defined as ≥3 stents implanted and/or ≥3 lesions treated, bifurcation stenting and/or stent length >60 mm, and/or chronic total occlusion revascularization. Ischemic and bleeding outcomes in high (≥25) or non-high (<25) PRECISE-DAPT strata were evaluated based on randomly allocated duration of DAPT. Results Among 14,963 patients from 8 randomized trials, 3,118 underwent complex PCI and experienced a higher rate of ischemic, but not bleeding, events. Long-term DAPT in non-HBR patients reduced ischemic events in both complex (absolute risk difference: −3.86%; 95% confidence interval: −7.71 to +0.06) and noncomplex PCI strata (absolute risk difference: −1.14%; 95% confidence interval: −2.26 to −0.02), but not among HBR patients, regardless of complex PCI features. The bleeding risk according to the Thrombolysis In Myocardial Infarction scale was increased by long-term DAPT only in HBR patients, regardless of PCI complexity. Conclusions Patients who underwent complex PCI had a higher risk of ischemic events, but benefitted from long-term DAPT only if HBR features were not present. These data suggested that when concordant, bleeding, more than ischemic risk, should inform decision-making on the duration of DAPT. (AU)

Changes in condylar volume and joint spaces after orthognathic surgery.

The aim of this study was to evaluate the changes in condylar volume and joint spaces occurring in patients undergoing bimaxillary orthognathic surgery for the treatment of class II deformities, by means of cone beam computed tomography (CBCT). Initial and follow-up (at least 6 months) CBCT examinations of 114 condyles (57 patients) were studied retrospectively. Linear measurements of the joint space and volumetric analysis of changes in condylar volume were performed using Dolphin 3D Imaging in association with ITK-SNAP 3.0.0 segmentation software. The paired t-test and Pearson correlation coefficient were applied, and a descriptive analysis was performed. Mean condyle volumes were significantly smaller at follow-up (P=0.0125). There were significant reductions in superior and medial joint spaces in the follow-up examinations (both P<0.05). Positive correlations were found when comparing the mean changes in anterior, superior, and posterior space values between the right and left sides. No significant correlation was observed between changes in volume and joint spaces. In conclusion, there was a reduction in mean condylar volume after orthognathic surgery in class II patients. However, changes in volume for each condyle may be variable. Such changes in condylar volume may occur independently on the left and right sides, and do not correlate with changes in joint spaces.

Intentionality of organ/tissues donation for transplantation within a Brazilian hospital complex.

OBJECTIVE: Considering the challenges faced by members of the Intrahospital Committee of Organ and Tissue Donation for Transplantation (CIHDOTT) of a Brazilian hospital complex in Santa Casa of Belo Horizonte in the execution of multiple donations of organs and tissues, this study aimed to investigate the issues involved in the intention to donate within this population. This research sought to promote the work of CIHDOTT by planning strategies for conducting of family interviews to best meet the needs of this population, thereby contributing to reduce the wait-list for transplantations in this state hospital of Minas Gerais. METHODS: The survey was performed by applying a standard questionnaire to 602 respondents comprising patients and families/caregivers. The analysis of the collected data was developed from studies of contingency tables based on chi- square and Fisher exact tests. RESULTS: The analysis revealed that 94% of the population to be favorable to donation. It also showed a significant influence of the following factors to determining the likelihood of organ donation: knowledge of religion (35%), spouse's opinion (17%), as well as belief in the possibility of interference or delay of the funeral as a result of donation (6%). CONCLUSION: Although the population expressed a willingness to donate, there were significant contravening factors that may be addressed by professional training and informational activities.
