Abstract

OBJECTIVE: Since minimally invasive surgery and general anesthesia are both aerosol-generating procedures, their use became controversial during the outbreak of coronavirus disease 2019 (COVID-19). Moreover, social distancing resulted in serious psychological consequences for inpatients. This case report investigates pain distraction during awake laparotomy, as well as new possibilities for emotional postoperative support to inpatients. PATIENTS AND METHODS: A 72-year-old man affected by middle rectal adenocarcinoma underwent lower anterior resection plus total mesorectal excision under combined spinal-epidural anesthesia. A 3D mobile theatre (3DMT) was intraoperatively used for pain distraction. A postoperative "Cuddle delivery" service was instituted: video-messages from relatives and close friends were delivered daily to the patient through the 3DMT. Emotional correlations were investigated through a clinical interview by the psychologist of our Hospital. RESULTS: Intraoperative, as well as postoperative pain, resulted well-controlled: visual analogue scale (VAS) ≤3. Conversion to general anesthesia and postoperative intensive support/monitoring were unnecessary. The "Cuddle delivery" initiative positively fed our patient's mood and attitude, strengthening his bond to life. CONCLUSIONS: During pandemic, awake laparotomy under loco-regional anesthesia may be a crucial option in delivering acute care surgery to selected patients when intensive care beds are unavailable. Our procedure introduces potential ways to optimize this approach. [ABSTRACT FROM AUTHOR]

Abstract

BACKGROUND: Functional pelvic disorders in patients undergoing conservative surgical approach for rectal cancer are considered a major public health issue and represent one third of cost of colorectal cancer. We investigated the hypothesis that lymphadenectomy, involves the pelvic floor results in a localized hides or silent pelvic lymphedema characterized by symptoms without signs. PATIENTS AND METHODS: We examined 13 colo-rectal cancer patients: five intra-peritoneal adenocarcinoma: 1 sigmoid and 4 upper third rectal cancer (1 male and 3 female) and 9 extra-peritoneal adenocarcinoma: 3 middle and 5 lower third rectal cancer (4 male and 5 female) using 1.5-T magnetic resonance, one week before and twelve months after discharged from hospital. RESULTS: Lymphedema was discovered on post-operative magnetic resonance imaging of all 9 patients with extra-pertitoneal cancer, whereas preoperative magnetic resonance imaging as well as a post-operative examination of 4 intra-peritoneal adenocarcinoma, revealed no evidence of lymphedema. Unlike the common clinical skin signs that typify all other sites of lymphedema, pelvic lymphedema is hides or silent, with no skin changes or any single symptom manifested. Magnetic resonance imaging showed that pelvic illness alone is accompanied by lymphedema related exclusively to venous congestion, and accumulation of liquid in adipose tissue or lipedema. CONCLUSIONS: Alteration of the pelvic lymphatic network during pelvic surgery can lead to lymphedema and, pelvic floor disease. Patients should be routinely examined for the possibility of developing this post-surgical syndrome and further studies are needed to establish diagnosis and to evaluate treatment preferences.

Abstract

Presentazione di Primo Levi narratore, focalizzata sulle opere di maggiore organicità e respiro: le due narrazioni testimoniali Se questo è un uomo e La tregua, il romanzo storico Se non ora, quando? e il lungo saggio sul fenomeno del Lager I sommersi e i salvati, cui va aggiunta l’autobiografia (rispetto ai canoni del genere, intenzionalmente frammentaria e reticente) Il sistema periodico. A differenza di quanto accade nelle narrazioni brevi, incentrate spesso (come ha scritto Federico Pianzola) sui temi della genesi e della metamorfosi, in queste opere Levi mostra di prediligere la forma della storia di salvazione, dove però l’esito appare sempre provvisorio, e insidiato da nuove minacce.

Abstract

In the symbiosis between rhizobia and legumes, host plants can form symbiotic root nodules with multiple rhizobial strains, potentially showing different symbiotic performances in nitrogen fixation. Here, we investigated the presence of mixed nodules, containing rhizobia with different degrees of mutualisms, and evaluate their relative fitness in the Sinorhizobium meliloti - Medicago sativa model symbiosis. We used three S. meliloti strains, the mutualist strains Rm1021 and BL225C and the non-mutualist AK83. We performed competition experiments involving both in vitro and in vivo symbiotic assays with M. sativa host plants. We show the occurrence of a high number (from 27% to 100%) of mixed nodules with no negative effect on both nitrogen fixation and plant growth. The estimation of the relative fitness as non-mutualist/mutualist ratios in single nodules shows that in some nodules the non-mutualist strain efficiently colonized root nodules along with the mutualist ones. In conclusion, we can support the hypothesis that in S. meliloti – M. sativa symbiosis mixed nodules are formed and allow non-mutualist or less-mutualist bacterial partners to be less or not sanctioned by the host plant, hence allowing a potential form of cheating behavior to be present in the nitrogen-fixing symbiosis.

Abstract

The fermented manure derivative known as Preparation 500 is traditionally used as a field spray in biodynamic agriculture for maintaining and increasing soil fertility. This work aimed at characterizing the product from a microbiological standpoint and at assaying its bioactive properties. The approach involved molecular taxonomical characterization of the culturable microbial community; ARISA fingerprints of the total bacteria and fungal communities; chemical elemental macronutrient analysis via a combustion analyzer; activity assays for six key enzymes; bioassays for bacterial quorum sensing and chitolipooligosaccharide production; and plant hormonelike activity. The material was found to harbor a bacterial community of 2.38 × 10(8) CFU/g dw dominated by Grampositives with minor instances of Actinobacteria and Gammaproteobacteria. ARISA showed a coherence of bacterial assemblages in different preparation lots of the same year in spite of geographic origin. Enzymatic activities showed elevated values of beta-glucosidase, alkaline phosphatase, chitinase, and esterase. The preparation had no quorum sensing-detectable signal, and no rhizobial nod gene-inducing properties, but displayed a strong auxin-like effect on plants. Enzymatic analyses indicated a bioactive potential in the fertility and nutrient cycling contexts. The IAA activity and microbial degradation products qualify for a possible activity as soil biostimulants. Quantitative details and possible modes of action are discussed.
