Indexing of Fatty Acids in Poultry Meat for Its Characterization in Healthy Human Nutrition: A Comprehensive Application of the Scientific Literature and New Proposals

Chicken meat is becoming the most consumed in the world for both economic and nutritional reasons; regarding the latter, the lipid profile may play positive or negative roles in the prevention and treatment of diseases. In this study, we define the state of the art of lipid-based nutritional indexes and used the lipid content and fatty acid profile (both qualitative and quantitative) of breast meat of two poultry genotypes with different growth rates and meat traits. Further, we summarize and review the definitions, implications, and applications of nutritional indexes used in recent years and others of our own design to provide a useful tool to researchers working in the field of meat quality (not only in poultry) to select the most appropriate index for their own scientific purposes. All indexes show advantages and disadvantages; hence, a rational choice should be applied to consider the nutritional effect of meat on human health and for a possible assessment of the most suitable rearing systems (genotype, feeding, farming system or postmortem handling).     

In situ adenocarcinoma and squamous carcinoma of uterine cervix. Pathological and immunohistochemical analysis with cytokeratin 13

OBJECTIVES: The aim of the study was the pathological and immunohistochemical analysis of cytokeratin 13 (CK13) in intraepithelial cervical tumors. STUDY DESIGN: We studied 415 in situ squamous carcinomas and 13 in situ mucinous cervical type adenocarcinomas of the uterine cervix. All patients underwent laser cervical conization and had a follow-up ranging 12-135 months. RESULTS: 3% of the squamous carcinoma patients recurred during the follow-up period, while the percentage of recurrence of in situ adenocarcinoma patients was 7.6%. We observed positive surgical edges in 46.1% of glandular tumors, and in 5% of squamous tumors. The percentage of recurrence was high among the cases with positive borders independently from their histopathologic type (14.3% in the squamous carcinomas versus 50% in the adenocarcinomas), compared to cases with negative edges (2.3% in the squamous carcinomas versus 0% in the adenocarcinomas). We observed CK13 positive staining in cervical squamous tumors and in mucinous cervical type adenocarcinomas, while there was no positive staining in non-neoplastic cervical glandular elements. CONCLUSION: CK13 positive immunostaining among in situ squamous and in situ mucinous cervical type adenocarcinoma cases adds additional evidence to data supporting a common origin of the two lesions.     

Congenital nasal pyriform aperture stenosis: diagnosis and management

ABSTRACT: BACKGROUND: Congenital nasal pyriform aperture stenosis is a rare and potentially lethal form of airway obstruction in newborns. Immediate recognition and appropriate therapy are mandatory for this potentially life-threating condition. This anomaly may present as an isolated malformation or may be associated with other cranial-facial anomalies. Clinically, CNPS shows unspecific symptoms of nasal airway obstruction such as apnoic crisis, episodic cyanosis and inability to nurse. The purpose of this report is to present author's experience in the surgical management of this rare pathology in 3 patients. Patients and Methods Three cases of congenital nasal pyriform aperture stenosis were reviewed for presentation of the disorder, management and effectiveness of the surgical treatment. RESULTS: All the patients underwent a surgical correction of the pyriform aperture stenosis using a sublabial approach followed by nasal stenting. During the follow-up no cases of restenosis, respiratory failure or cyanosis were detected. CONCLUSIONS: Congenital pyriform aperture stenosis should be suspected in newborns with clinical signs of severe nasal obstruction associated with a difficulty to pass a small catheter though the anterior nasal valve. Timely recognition is mandatory to prevent a potential deadly outcome. Surgical correction of the stenosis though a sublabial approach followed by a nasal stenting revealed to be most effective treatment for these patients.     

(In)accuracy of blood pressure measurement in 14 Italian hospitals

OBJECTIVES:: The diagnosis and control of hypertension depend on accurate measurement of blood pressure (BP). The literature on the accuracy of BP recording by health professionals is, however, limited, and no study directly interviewed patients in the hospital setting. This multicenter cross-sectional study aimed at evaluating the compliance to current recommendations on BP measurement by health professionals directly from patients and to investigate potential predictors of higher quality in BP recording. METHODS:: A trained nurse interviewed a random sample of adult patients hospitalized for an ordinary admission (except in the emergency room) lasting more than one night, without mental disorder, who had their BP routinely measured by the hospital personnel less than 3?h before. The questionnaire contained 15 items on the main procedures that are common to current guidelines. RESULTS:: Fourteen public hospitals from seven regions of Italy participated, and 1334 questionnaires were collected. Nine of the recommended practices were followed in the majority (>70%) of BP recordings, whereas some others were infrequent or rare: in 98.6, 82.2 and 81.1% of the participants, respectively, the arm circumference was never recorded, BP was measured only once, and BP was never recorded in both arms. Overall, 10 or more recommended procedures were followed during 33.4% recordings. At multivariate analysis, physicians were less likely than nurses to provide a more accurate BP measurement. CONCLUSIONS:: The operator's compliance to some recommendations in BP measurement is unacceptably low. This survey provides detailed indications for medical directors on the procedures and settings to prioritize in educational programs, which are definitely needed.     

Exploring the reciprocal modulation of time and space in dancers and non-dancers

We explored whether time and space representations modulate each other in subjects that are trained to integrate time and space dimensions, i.e., professional dancers. A group of dancers, and one of non-dancers, underwent two different tasks employing identical stimuli. A first static central line could last one of three possible durations and could have one of three possible lengths. A second growing line appeared from the left or right of the screen and grew up toward the opposite direction at constant velocity. In the Spatial task, subjects encoded the length of the static line and stopped the growing line when it had reached half the length of the static one, regardless of time travel. In the Temporal task, subjects encoded the duration of the static line and stopped the growing line when it had lasted half the duration of the static one, regardless of space traveled. Dancers, differently from non-dancers, anticipated time in the Temporal task. However, both dancers and non-dancers were biased by the stimulus length when performing the Temporal task, while they were not biased by the stimulus duration when performing the Spatial task. Concluding, this study underlines the plasticity of time dimension that can be influenced by spatial information and by sensorimotor training for the synchronization in space and time.
