Tessuti riciclati sostenibili basati sulle tende beduine tradizionali
No full textIl mondo sta affrontando una crisi di rifugiati in costante crescita. Questa problematica è particolarmente visibile in Europa, a causa della guerra in Ucraina o dei conflitti in Paesi come Siria, Giordania e Sud Sudan. I rifugiati sono spesso alloggiati in tende che non offrono alcun comfort. La presente ricerca indaga i tessuti tradizionali beduini e il loro potenziale come soluzione innovativa e sostenibile da applicare alle tende, soprattutto nelle regioni in cui sono frequenti condizioni climatiche estreme. In particolare, si considera il potenziale della lana riciclata come materiale ecologico, testando l'uso di lana di capra riciclata per produrre un tessuto utilizzabile in contesti multipli. Inoltre, la ricerca mira ad ampliare la conoscenza della progettazione delle tende, dei materiali e dei processi utilizzati dalle tribù nomadi per proporre una soluzione innovativa che migliori le qualità termiche dei tessuti utilizzati nelle tende dei rifugiati. Lo studio fornisce un’analisi dei casi di studio di tende beduine in Giordania, Egitto e Libano relativi alla progettazione dei materiali e all'artigianato tradizionale. La ricerca è proseguita tramite interviste ad personam ad artigiani esperti che utilizzano fibre e lana di capra, pecora e cammello naturali e riciclate per ottenere informazioni sulla disponibilità, le proprietà e la sostenibilità della lana. Inoltre la ricerca dimostra che la lana e fibre tessili riciclate sono adatte alla realizzazione di tende confortevoli e sostenibili per i campi profughi nelle regioni aride e semi-aride. Lo studio evidenzia la possibilità di adottare in contesti precedentemente citati, materiali sostenibili che seguono le proprietà di riciclabilità, isolamento termico e assorbimento dell'umidità

Moderately increased hemolysis in newborn infants with hyperbilirubinemia of unknown etiology
No full textSerial determinations of carboxyhemoglobin (COHb) levels were performed in full-term newborn infants during the first few days of life and their mothers. A close correlation was found between COHb in the mother and that determined in the cord blood. The correlation between COHb in the mother at delivery and that found in the neonate disappeared after 48 h of life. The determination of COHb after this period demonstrated significantly higher values of COHb levels in jaundiced neonates compared with normal infants. Determinations of erythrocyte age-dependent enzyme activities carried out at birth and after 5 days of life did not demonstrate any significant difference between the mean values in jaundiced and normal infants. However, the normal infants demonstrated a decrease of glucose-6-phosphate dehydrogenase and pyruvate-kinase activities from birth to the 5th day which is not appreciable in neonates with hyperbilirubinemia of unknown etiology. The results are discussed in relation to the role of hemolysis in neonatal hyperbilirubinemia
Variations in erythrocyte enzymatic activity in the first days of life [Variazioni di attività enzimatiche eritrocitarie nei primi giorni di vita]
No full textThe erythrocyte activities of glucose 6-phosphate dehydrogenase, pyruvate kinase and glucose phosphate isomerase decrease during the first days of life. Furthermore the level of these enzymatic activities is higher in newborn infants with higher percentage of carboxyhemoglobin. It is likely that a premature and rapid fall of reticulocytes causes a decrease in enzymatic activities sensitive to aging and that the higher hemolysis can represent a disappearance of oldest erythrocytes which present lower enzymatic activities. These data therefore confirm the block in erythropoiesis in the first hours of life
The fat anchor orchiopexy technique: results and outcomes from 150 cases surgical experience
No full textPurpose: The purpose of the study is to evaluate results and outcomes in a long-time follow-up period, by performing a novel testicular fixation procedure, known as “fat anchor orchidopexy” (FAO), for the treatment of palpable low inguinal undescended testis. Materials and methods: We retrospectively reviewed all patients who underwent scrotal orchiopexy technique, from May 2013 to May 2019, at the Pediatric Surgery Division of Department of Surgical Pathology, University of Pisa (Italy). FAO (Spinelli’s technique) consists in anchoring the testicles to sub-scrotal fat with a single trans-scrotal incision. All the patients enrolled had history of unilateral or bilateral undescended testis. Data collected included patient’s age, operative times and complications. Results: A total of 150 children with cryptorchidism were treated using a single trans-scrotal orchiopexy. Of them, 130 patients (86.7%) had unilateral undescended testis and 20 (13.3%) bilateral cryptorchidism. Mean patient’s age was 21 months (range: 14–28 months). All the procedures were planned in a day-surgery setting. Trans-scrotal orchiopexy was successful in all cases and no patients required an additional groin incision. No intraoperatively and postoperatively major complications were observed. Patients’ post-operative pain was mild (mean pediatric visual analog scale = 2). In all cases, the healing process was rapid and no surgical wounds infections were reported during the post-operative period, referring excellent cosmesis results. During a mean 48-month follow-up period, no testicular retraction, recurrence or testis atrophy was reported. Conclusion: The original Spinelli’s technique (FAO) proves to be a safe and effective method for the treatment of palpable or distal-to-external-inguinal-ring testes. No immediate and delayed post-surgery complications were reported. In all cases, the anchored testicle remained in the scrotal position with normal vascularization. This novel surgical technique could give better options for scrotal fixation in case of low-lying cryptorchid testes
