Abstract
The consumption of raw milk or raw milk products might be a potential risk factor for the transmission of methicillin-resistant Staphylococcus aureus (MRSA). Therefore, we studied MRSA growth during raw milk soft cheese-production. Furthermore, we investigated the inhibitory effect of four starter cultures (Lactococcus lactis, Lacticaseibacillus rhamnosus, Lactiplantibacillus plantarum, Lactobacillus helveticus) on the growth of MRSA in a spot-agar-assay and in raw milk co-culture following a cheesemaking temperature profile. During the initial phases of raw milk cheese-production, MRSA counts increased by 2 log units. In the ripening phase, MRSA counts only dropped slightly and remained high up to the end of the storage. Comparable MRSA counts were found in the rind and core and strain-specific differences in survival were observed. In the spot-agar-assay, all four starter cultures showed strong or intermediate inhibition of MRSA growth. In contrast, in raw milk, only Lactococcus lactis strongly inhibited MRSA, whereas all other starter cultures only had minor inhibitory effects on MRSA growth. Our results indicate that MRSA follow a similar growth pattern as described for other S. aureus during raw milk soft cheese-production and illustrate the potential use of appropriate starter cultures to inhibit MRSA growth during the production of raw milk cheese.

Abstract
Poultry is a common reservoir for Campylobacter and a main source for human campylobacteriosis. With broiler being the predominant poultry for food production, most food safety related research is conducted for this species, for turkey, few studies are available. Although animals are typically colonized at the farm level, the slaughtering process is considered an important factor in re- and cross-contamination. We examined the development of Campylobacter, E. coli and total colony counts (TCC) after several processing steps in three broiler and one turkey slaughterhouses. Whole carcass rinsing and neck skin sampling was applied for broilers resulting in 486 samples in total, while 126 neck skin samples were collected for turkeys. A decrease in the loads of the different bacterial groups along the broiler slaughtering process was observed. Campylobacter mean counts dropped from 4.5 ± 1.7 log10 CFU/ml after killing to 1.6 ± 0.4 log10 CFU/ml after chilling. However, an increase in Campylobacter counts was evident after evisceration before the values again decreased by the final processing step. Although the Campylobacter prevalence in the turkey samples showed a similar development, the bacterial loads were much lower with 1.7 ± 0.3 log10 CFU/g after killing and 1.7 ± 0.4 log10 CFU/g after chilling compared to those of broilers. The loads of E. coli and total colony count of turkey were higher after killing, were reduced by scalding and remained stable until after chilling. This study highlights trends during the slaughtering process in reducing the levels of Campylobacter, E. coli, and total colony counts for broiler and turkey carcasses, from the initial step to after chilling. These results contribute to our understanding of microbial dynamics during meat processing.

Abstract
BACKGROUND Textbook outcome (TO) is a composite variable that can define the quality of pancreatic surgery. The aim of this study is to evaluate TO after pancreatoduodenectomy (PD) for nonfunctioning pancreatic neuroendocrine tumors (NF-PanNETs). PATIENTS AND METHODS All patients who underwent PD for NF-PanNETs (2007-2016) in different centers were included in this retrospective study. TO was defined as the absence of severe postoperative complications and mortality, length of hospital stay ≤ 19 days, R0 resection, and at least 12 lymph nodes harvested. RESULTS Overall, 477 patients were included. The TO rate was 32%. Tumor size [odds ratio (OR) 1.696; p = 0.013], a minimally invasive approach (OR 12.896; p = 0.001), and surgical volume (OR 2.062; p = 0.023) were independent predictors of TO. The annual frequency of PDs increased over time as well as the overall rate of TO. At a median follow-up of 44 months, patients who achieved TO had similar disease-free (p = 0.487) and overall survival (p = 0.433) rates compared with patients who did not achieve TO. TO rate in patients with NF-PanNET > 2 cm was 35% versus 27% in patients with NF-PanNET ≤ 2 cm (p = 0.044). Considering only NF-PanNETs > 2 cm, patients with TO and those without TO had comparable 5-year overall survival rates (p = 0.766) CONCLUSIONS: TO is achieved in one-third of patients after PD for NF-PanNETs and is not associated with a benefit in terms of long-term survival.

Abstract
OBJECTIVE To provide an overview of the current practice of intraoperative blood loss (BL) estimation in hepato-pancreato-biliary (HPB) surgery. BACKGROUND Intraoperative BL is a major quality marker in HPB surgery and a predictor of perioperative outcomes. However, the method for BL estimation is not standardized. METHODS A systematic review was performed of original studies published between 2006 and 2021 reporting the intraoperative BL of patients undergoing pancreatic or hepatic resections. A web-based snapshot survey was distributed globally to all members of the International Hepato-Pancreato-Biliary Association (IHPBA). RESULTS A total of 806 studies were included; 480 (60%) had BL as their primary outcome, and 105 (13%) had BL as their secondary outcome. However, 669 (83%) did not specify how BL estimation was performed, and 9 different methods were found among the remaining 136 (17%) studies.The survey was completed by 252 surgeons. Most of the responders (94%) declared that they systematically performed BL estimation and considered BL predictive of postoperative complications after pancreatic (73%) and liver (74%) resection. All methods previously identified in the literature were used by responders with different frequencies. A calculation based on suction fluid amounts, operative gauze weight, and irrigation was the most used method in the literature (7%) and among responders (51%). Most responders (83%) felt that BL estimation in HPB surgery needs improved standardization. CONCLUSIONS Standardization of intraoperative BL estimation is urgently needed in HPB surgery to ensure the consistency of reporting and reproducibility.

Abstract
Active packaging films based on gelatin with silver-kaolinite (Ag-Kln) were developed and their effects on the quality and microbial growth of beef meat stored in different packaging systems (cling film, vacuum and modified atmosphere packaging) at 4 °C for 13 days were evaluated. The analysis revealed that Ag-Kln packaging films had no adverse effects on the pH and colour of the beef samples irrespective of the packaging system used. Beef meat in packaging with active films lost more weight (P < 0.05) than without active films for meat in the vacuum and modified systems on day 13. In general, these gelatin films with Ag-Kln showed the potential as antibacterial films and could enhance the shelf life of food products, however, further studies are required to establish the release rate of silver from packaging films, as well as test the efficiency of these materials under different storage conditions. In conclusion, this study revealed that gelatin film with silver-kaolinite is a promising antibacterial agent and preservation material for food shelf life extension.

Abstract
Background and aim This study analyses the impact of the first two pandemic waves on surgical urgencies/emergencies and their consequences on an entire provincial hospital network's surgical activities. Methods Clinical and epidemiological data of urgent/emergent surgical admissions and interventions in the Autonomous Province of Trento's hospital network were collected from the internal common electronic database. The investigation periods were March-May 2019 (reference period), March-May 2020 (phase-I), June - August 2020 (phase-II), and October - December 2020 (phase-III). The same data were divided and grouped for the six most represented diagnoses. Results: The number of admissions for surgical emergencies in the studied periods showed a sinusoidal trend. In the reference period of 2019, 957 patients were admitted in urgency, while in the three pandemic phases, urgent admissions were 511, 888 and 633 respectively (-47% in phase I, - 8% in phase II, -34% in phase III). This trend was also observed by stratifying admissions for single disease, except for gastrointestinal perforations and pancreatitis, which showed a slight increasing trend in phase-I. Among the studied population, the surgical rate was 35.2% in phase-I and 34.3% in phase-III; these data were significantly higher than in 2019 (25.6%). Conclusions The effect of the COVID pandemic on surgical emergencies and urgencies (SUEs) was mainly indirect, manifesting itself with a significant reduction in the number of surgical admissions, particularly in phases-I and-III. Conversely, in the same phases, the surgical rate showed a significant increase compared to 2019.

Abstract
OBJECTIVES to analyse both direct and indirect impacts on surgical admissions, surgical rates, and clinical picture severity of the two COVID-19 pandemic waves in a hospital network covering an entire province (Trento, located in Trentino-Alto Adige Region, Northern Italy). DESIGN retrospective epidemiological study. SETTING AND PARTICIPANTS data regarding the patient load of the Surgical Urgencies/Emergencies flows (SUEs) of the Local Health Authority of the Autonomous Province of Trento derived from the Hospital Discharge Record (HDR) information flow. The population in study was that of patients hospitalized in the entire Province of Trento. This study compares the volume and characteristics of urgent/emergency surgery during the 2020 COVID-19 pandemic with the homologous period in 2019, subdividing the analysed pandemic period in 3 separated groups: • phase I (March-May 2020); • phase II (June-August 2020); • phase III (October-December 2020). The 3 groups represent, respectively: the 1st pandemic wave proclamation of national lockdown from 9 March to 18 May; the summer pandemic remission; the 2nd pandemic wave with partial restrictions on circulation and commercial activities. Clinical and surgical records of SUE population among these 3 periods (March-May; June-August; October-December) of both 2020 and 2019 were analyzed and compared. MAIN OUTCOME MEASURES the overall number of admissions and surgical rates for SUEs in the study periods were chosen as primary outcomes. The same outcomes were analysed for the most represented diagnoses in the SUEs population: diverticulitis, intestinal obstruction, appendicitis, cholecystitis, gastrointestinal (GI) perforations, pancreatitis, traumas. To assess the degree of clinical picture severity, variables coming from the hospital discharging charts, commonly associated to worst outcomes in term of mortality and morbidity, such as age, length of hospital stay, DRG weight, and patients not discharged at home were extrapolated from the electronic database. A numerical weight was then assigned to each variable, obtaining a scoring system from 0 to 15 (severity index). RESULTS the number of admissions for SUEs in the studied period showed a sinusoidal trend, with a dramatic decrease in phase I and III (-46.6% and -31.6%, respectively). This trend was also observed even by stratifying admissions for the most frequent pathologies, except for gastrointestinal perforations and pancreatitis. The surgical rate among hospitalised patients for SUEs was 35.2% in phase, significantly higher than that of 2019 (25.6%). Considering the most frequent diagnoses individually, some had a progressive increase in the surgical rate in phases I and II (diverticulitis, bowel obstructions, cholecystitis), others showed an initial decrease and then settled on values not far from those of 2019 (GI perforations and appendicitis), others again had an initial significant increase and then gradually returned to values similar to those of 2019 in phase III (traumas). The mean patients age was significantly higher in phase I than in 2019 (p-value <0.001) and in phase II (p-value <0.05). Consistently with the trend of the number of urgent admissions, even the severity index calculated on the SUEs population showed a sinusoidal trend with and evident increase during the two pandemic waves. CONCLUSIONS the effect of the COVID-19 pandemic on SUEs was mainly indirect, manifesting itself with a significant reduction in surgical admissions, particularly in phases I and III. Conversely, in the same phases, the surgical rate showed a significant increase compared to 2019. The stratified analysis confirmed these findings for the most frequent diagnoses except for GI perforations and pancreatitis. The clinical pictures were more severe in the two pandemic waves than in the reference period of 2019. Although with a slight numerical attenuation, in general, the second pandemic wave confirmed the first one findings.

Abstract
BACKGROUND The purpose of this study was to identify which clinicopathological features of early-stage rectal cancer (ESRC) are significantly correlated with the risk of local-regional lymph node metastases (LNM) and to quantify the strength of this association through a novel scoring system. According to several case studies, about 20% of operated ESRC are found with occult lymph nodal metastases at the histological examination. The low frequency of local recurrence in these tumours treated with total mesorectal excision (TME) compared to transanal approaches highlights the role of mesorectal lymph nodes as a site of metastatic location. METHODS 386 consecutive patients with ESRC treated with radical resection and TME were examined in a retrospective, observational multi-centric study, operated between 2007 and 2019 in seven centres. Demographic and tumour related clinicopathological characteristics were identified, collected and analysed. Each variable was specifically weighted based on the strength of its association with the presence of nodal metastases. A scoring system using these weighted variables was developed. RESULTS Six variables were found to be significantly associated with local regional LNM: lymphatic invasion combined with vascular invasion, poor differentiation (G3), stage T2, age ≥60 years, male sex, perineural invasion. A novel scoring system weighted on the presence of each of these variables able to quantify the risk of LNM in ESRC was developed. CONCLUSIONS The proposed scoring system is a good predictor of the risk of LNM and should be of help in the decision-making process for ESRC cases diagnosed either by local excision or endoscopic biopsy.

Abstract
Ready-to-eat (RTE) sliced emulsion type sausages are sensitive to recontamination with Listeria (L.) monocytogenes during processing and packaging steps. Since Listeria spp. are able to grow on those products under cold storage conditions, taking steps to reduce the recontamination risk and implementing antibacterial hurdles contribute to consumer safety and increase the product quality. With this study data about the suitability of culture broth, cell-free supernatant (CFS) or concentrated bacteriocin preparations (CFSconc) of bacteriocin-producing lactic acid bacteria (LAB) obtained from fermented sausages from Germany as protective culture or antibacterial additive were provided. In different challenge tests, the potential of selected LAB or their preparations were investigated for their potential to reduce growth of L. monocytogenes and/or Brochothrix (B.) thermosphacta on sliced RTE emulsion type sausages under modified atmosphere or vacuum during refrigerated storage for a 21-day period. Applied LAB culture broth and CFS could not reduce the growth of L. monocytogenes or B. thermosphacta. On the other hand, samples treated with CFSconc obtained from Pediococcus spp. strains showed a significant inhibition (p < 0.05) of more than 1.5 log10 of the applied L. monocytogenes strains during the storage period. The growth of B. thermosphacta could not be influenced. Thereby, the need for concentrating preparations was shown to be important to obtain a suitable antibacterial preparation that would contribute to consumer safety and food quality when applied as a protective additive.

Abstract
One of the main reasons for condemning fattening broiler chickens during meat inspection is cellulitis, which demonstrates the great economic issue concerning this topic. The aim of this epidemiological study was therefore to identify risk factors in order to draw conclusions on how to prevent the occurrence of cellulitis in broilers by implementing management changes. The data were collected between April and November 2018 on conventional broiler farms (n = 100) in the north of Germany with one to fourteen poultry houses per farm. In total, data were collected from 199 broiler flocks with a total of 5,332,767 broilers. Data on the type of management (feeding- and drinking management, housing, lighting management, litter type and animal health) were collected via a questionnaire, with additional data on condemnation rates being provided by the abattoirs. It was found that litter additives like fennel, eucalyptus and probiotics as well as a moist litter quality were associated with lower cellulitis condemnation rates. Flocks fattened in windowless barns, but with relatively higher lux-values as well as those broilers examined in a lower number of housing inspections had significantly lower cellulitis condemnation rates compared to other husbandry systems. In addition, lower cellulitis rates were seen when housing capacities were smaller, regardless of stocking density. The source of the breeders and hatchery also had a significant influence on the occurrence of cellulitis. No correlation was found between the condemnation rates due to cellulitis and the performance of thinning, the water source used, the use of drinking additives, observational skills and number of herd managers monitoring the broilers, participation in an animal welfare programme, the technique of heating and ventilation systems used, the feed supplier, litter material, the broiler breed, the length of darkness periods and chick losses during the first seven days. We concluded that management decisions that lead to stress reduction in the broiler flocks are beneficial in terms of chicken welfare and occurrence of cellulitis.

Abstract
Staphylococcus aureus (S. aureus) is an important causative agent of contagious intermammary infections in dairy cattle. S. aureus is also considered as an important foodborne pathogen and cause of food poisoning cases and outbreaks worldwide. In order to understand the molecular ecology of S. aureus, the present study compared phenotypic and genotypic characteristics of 70 S. aureus isolates from bovine mastitis milk samples collected during the period from August 2001 to March 2014 in different regions of Northern Germany. The S. aureus isolates were characterised phenotypically, as well as genotypically for their genetic diversity using multi-locus sequence typing (MLST), spa typing and the presence of virulence genes encoding 16 staphylococcal enterotoxins (sea-selu), toxic shock syndrome toxin (tst), thermonuclease (nuc), clumping factor (clfA and clfB), coagulase (coa) and the methicillin resistance gene mecA. A total of 16 sequence types were grouped into eight clonal complexes (CCs), and 17 spa types were identified. These included six novel sequence types and one novel spa type. The majority of bovine mastitis milk-associated sequence types belonged to the clonal complex CC5, CC97, CC133, and CC151 and showed closely related genotypes or lineages with sequence types of human origin. The genotype CC133 (ST133-t1403) was predominant, constituting 27.1% of the isolates. In addition, the S. aureus isolates displayed nine different enterotoxigenic profiles. All S. aureus were methicillin-susceptible (MSSA). The current study provides new information on phenotypic and genotypic traits of S. aureus isolates from bovine mastitis. The comparison of characteristics of isolates from the present study originating from mastitis milk showed similarities with human isolates. This might help to better understand the distribution of S. aureus in the one health context.

Abstract
Transgenic technology provides one approach for examining cytokine properties in vivo. This study directly tested the effect of a lung-targeted IL-13 transgene on the induction and elicitation of Th1 and Th2 cell-mediated immuno-inflammatory responses. Induction of Th1 (type 1) and Th2 (type 2) responses were tested by sensitization of IL-13 transgenics and littermates with purified protein derivative (PPD) of Mycobacterium bovis or Schistosoma mansoni eggs. Secondary elicitation of pulmonary granulomas was examined in adoptively sensitized transgenics and littermates challenged with bead-bound PPD or S. mansoni egg antigens. Parameters included lymphoid tissue cytokine profiles and granuloma sizes. Results showed that induction and elicitation of both type 1 and type 2 cytokines and granulomas were significantly abrogated in transgenics. Systemic effects were possible, as transgenic serum contained high levels of circulating IL-13. These findings support the concept that IL-13 impairs effector functions and provide novel information regarding its role in regulating Th2 cytokines.

Abstract
Transcript expression of 24 chemokines (CKs) was examined throughout 8 days in mouse lungs with type-1 (Th1) or type-2 (Th2) cytokine-mediated granulomas induced by bead-immobilized mycobacterial purified protein derivative or Schistosoma mansoni egg antigens. Where possible, CK protein levels were also measured. In addition, we examined effects of in vivo cytokine depletions. Findings were as follows: 1) bead challenge induced increases in 18 of 24 CK transcripts with type-1 and type-2 responses displaying different patterns. CKs fell into four categories: a) type-1-dominant (gamma-interferon-inducible protein (IP-10), monokine induced by INF-gamma (MIG), macrophage inflammatory protein-2 (MIP-2), lipopolysaccharide-induced chemokine (LIX), rodent growth-related oncogene homologue (KP), macrophage inflammatory protein-1alpha (MIP-1alpha) and -1beta (MIP-1beta), lymphotactin), b) type-2-dominant (eotaxin, monocyte chemotactic protein-2 (MCP-2) and -3 (MCP-3), liver and activation-regulated chemokine (LARC), T cell activation protein-3 (TCA-3), c) type-1 and type-2 co-dominant (MCP-1, MCP-5, monocyte-derived chemokine (MDC), thymus and activation-related chemokine (TARC), C10), and d) constitutive (lungkine, secondary lymphoid-tissue chemokine (SLC), EBI1-ligand chemokine (ELC), fractalkine, macrophage inflammatory protein-1gamma (MIP1-gamma), and stromal cell derived factor-1alpha (SDF1-alpha). 2) CKs displayed characteristic temporal patterns. CXC (IP-10, MIG, MIP-2, LIX, KC) and certain CC (MCP-1, MCP-5, MIP-1alpha, MIP-1beta) CKs were produced maximally within 1 to 2 days. Others (MCP-2, MCP-3, eotaxin, lymphotactin, LARC, TCA-3) displayed peak expression later. 3) Interferon-gamma neutralization profoundly abrogated MIG, but had little effect on other CKs. Tumor necrosis factor-alpha neutralization caused up to 50% reduction in a range of CKs. These findings indicate that type-1 and type-2 granulomas display characteristic CK profiles with coordinated expression that is under cytokine-mediated regulation.

Abstract
Standard 12 lead electrocardiograms (ECG) and Frank vectorcardiograms (VCG) were recorded in 21 consecutive patients with mitral valvular disease and angiographically documented left atrial enlargement. Comparative sensitivities for the detection of left atrial enlargement were: diagnostic, ECG = 6/21 (29%), VCG = 14/21 (67%); suggestive, ECG = 3/21 (14%), VCG = 2/21 (9%); non-diagnostic, ECG = 12/21 (57%), VCG = 5/21 (24%). It is concluded that the Frank atrial vectorcardiogram is superior to the standard electrocardiogram for the diagnosis of left atrial enlargement.
