ABSTRACT

Biological control using edible mushrooms as natural enemies is a sustainable alternative for pest management. Despite the well-established literature on toxins and secondary metabolites produced by these fungi in the biochemical control of nematodes, the nematicidal activity of proteases from different Pleurotus species is yet to be investigated. Therefore, this study aimed to correlate protease to the nematicidal activity of different mushrooms, Pleurotus sp., P. ostreatus (SB), P. ostreatus (Pearl), and P. djamor. For such a purpose, we performed motility assays of Panagrellus sp. at different time intervals, 6, 12, and 24 h for each of the mushrooms. In addition, the protease activity was measured using different pH (5, 7, and 9) and fermentation time intervals (45 and 75 days). Furthermore, we also evaluated the effect of this cell-free extract on Panagrellus sp. In response to these experiments, all edible mushrooms showed a reduction over 82% for the nematode-feeding activity (p < 0.01). The cell-free crude extract of each of the fungi studied showed nematocidal activity (p < 0.01). For the 45-day fermentation, P. djamor exhibited statistical significance (p < 0.01) compared with the others, reaching a reduction percentage of 73%. For the 75-day fermentation, Pleurotus sp. and P. ostreatus (Pearl) showed significant differences compared with the other fungi (p < 0.01), with reduction percentages of 64 and 62%, respectively. Herein, protease activity was associated with the nematicidal action of different Pleurotus species in controlling Panagrellus sp.

ABSTRACT

PURPOSE: To compare the inter-reader agreement of pancreatic adenocarcinoma resectability assessment at pancreatic protocol photon-counting CT (PCCT) with conventional energy-integrating detector CT (EID-CT).

METHODS: A retrospective single institution database search identified all contrast-enhanced pancreatic mass protocol abdominal CT performed at an outpatient facility with both a PCCT and EID-CT from 4/11/2022 to 10/30/2022. Patients without pancreatic adenocarcinoma were excluded. Four fellowship-trained abdominal radiologists, blinded to CT type, independently assessed vascular tumor involvement (uninvolved, abuts ≤ 180°, encases > 180°; celiac, superior mesenteric artery (SMA), common hepatic artery (CHA), superior mesenteric vein (SMV), main portal vein), the presence/absence of metastases, overall tumor resectability (resectable, borderline resectable, locally advanced, metastatic), and diagnostic confidence. Fleiss’s kappa was used to calculate inter-reader agreement. CTDIvol was recorded. Radiation dose metrics were compared with a two-sample t-test. A p < .05 indicated statistical significance.

RESULTS: 145 patients (71 men, mean[SD] age: 66[9] years) were included. There was substantial inter-reader agreement, for celiac artery, SMA, and SMV involvement at PCCT (kappa = 0.61-0.69) versus moderate agreement at EID-CT (kappa = 0.56-0.59). CHA had substantial inter-reader agreement at both PCCT (kappa = 0.67) and EIDCT (kappa = 0.70). For metastasis identification, radiologists had substantial inter-reader agreement at PCCT (kappa = 0.78) versus moderate agreement at EID-CT (kappa = 0.56). CTDIvol for PCCT and EID-CT were 16.9[7.4]mGy and 29.8[26.6]mGy, respectively (p < .001).

CONCLUSION: There was substantial inter-reader agreement for involvement of 4/5 major peripancreatic vessels (celiac artery, SMA, CHA, and SMV) at PCCT compared with 2/5 for EID-CT. PCCT also afforded substantial inter-reader agreement for metastasis detection versus moderate agreement at EID-CT with statistically significant radiation dose reduction.

ABSTRACT

Extracorporeal shock wave lithotripsy (ESWL) is a safe and efficient treatment option for urinary stone disease. The overall stone-free rate (SFR) varies significantly. This study aimed to assess the influence of stone size, location, stone density, and skin-to-stone distance (SSD), on the outcome of ESWL. We assessed whether pre-treatment non-contrast-enhanced CT scan (NCCT) confers significant advantages compared to kidney-ureter-bladder film (KUB) only. We reviewed the medical records of 307 cases (165 men, 142 women) with renal and ureteral stones treated consecutively at our institution with ESWL between 2020 and 2023. 44 of these underwent a NCCT. The outcome of ESWL was defined in two ways: visible stone fragmentation on KUB, and the need for further treatment. Overall success of fragmentation was 85% (261 patients). 61% of patients (n = 184) didn’t need any further treatment. Stone size and location correlated significantly with treatment outcomes regarding the need for further treatment (p = 0.004) and stone fragmentation (p = 0.016), respectively. Unlike mean SSD (p = 0.462), the mean attenuation value (MAV) significantly correlated with the need for retreatment (p = 0.016). MAV seems to be a better predictor of treatment success (AUC of the ROC curve: 0.729), compared to stone size (AUC: 0.613). The difference between groups (with and without NCCT) in both treatment outcomes did not reach statistical significance. During decision-making, information regarding SSD and MAV can be useful in more dubious scenarios. However, it appears that their inclusion doesn’t provide substantial advantages when compared to relying solely on KUB.

ABSTRACT

PURPOSE: The purpose of this study was to statistically compare the rate of torque development normalized by maximal strength (relative RTD) across ankle angles. Additionally, this study was aimed at exploring the correlation coefficients between relative RTD and passive stiffness of the medial gastrocnemius (MG) at different ankle angles.

METHODS: Twenty-two healthy men and women (age: 31 ± 4 years) performed randomly-ordered explosive isometric plantar flexions at plantarflexed (15°), neutral (0°), and dorsiflexed (- 15°) angles; relative RTD comprised the slope of the time-torque curve normalized to maximal torque. The shear wave velocity (SWV; index of stiffness) of the MG at rest was measured at each angle using ultrasound shear wave elastography.

RESULTS: The relative RTD was greater at 15° than – 15° for 0-50, 0-100, and 0-150 ms time-windows and at 15° than 0° for the 0-150 ms time-window (P < 0.05), although peak torque was lower at 15° than 0° and – 15° (P < 0.05). The relative RTD for the 0-50 ms time-window correlated with SWV at – 15° (r_s = 0.475, P < 0.05), but not at 15º and 0º. Furthermore, the correlation coefficient of RTD for the 0-100 ms time-window with SWV was significantly greater at – 15° (r_s = 0.420) than 0 ° (r_s = – 0.109).

CONCLUSIONS: A greater relative RTD occurs at plantarflexed angles (i.e., the ascending limb of the force-length curve) in the triceps surae, and relative RTD is strongly related to passive MG stiffness at dorsiflexed angles (i.e., longer muscle lengths).

ABSTRACT

BACKGROUND: Tracheobronchomalacia (TBM) is characterized by excessive dynamic airway collapse. Severe TBM can be associated with substantial morbidity. Children with secondary TBM associated with esophageal atresia/tracheoesophageal fistula (EA/TEF) and vascular-related airway compression (VRAC) demonstrate clinical improvement following airway pexy surgery. It is unclear if children with severe primary TBM, without secondary etiologies (EA/TEF, vascular ring, intrinsic pulmonary pathology, or complex cardiac disease) demonstrate clinical improvement following airway pexy surgery.

MATERIALS AND METHODS: The study cohort consisted of 73 children with severe primary TBM who underwent airway pexy surgery between 2013 and 2020 at Boston Children’s Hospital. Pre- and postoperative symptoms as well as bronchoscopic findings were compared with Fisher exact test for categorical data and Student’s t-test for continuous data.

RESULTS: Statistically significant improvements in clinical symptoms were observed, including cough, noisy breathing, prolonged respiratory infections, pneumonias, exercise intolerance, cyanotic spells, brief resolved unexplained events (BRUE), and noninvasive positive pressure ventilation (NIPPV) dependence. No significant differences were seen regarding oxygen dependence, ventilator dependence, or respiratory distress requiring NIPPV. Comparison of pre- and postoperative dynamic bronchoscopy findings revealed statistically significant improvement in the percent of airway collapse in all anatomic locations except at the level of the upper trachea (usually not malacic). Despite some initial improvements, 21 (29%) patients remained symptomatic and underwent additional airway pexies with improvement in symptoms.

CONCLUSION: Airway pexy surgery resulted in significant improvement in clinical symptoms and bronchoscopic findings for children with severe primary TBM; however, future prospective and long-term studies are needed to confirm this benefit.

ABSTRACT

BACKGROUND: Bronchopulmonary Dysplasia (BPD) has a multifactorial etiology. Vitamin E and vitamin D play an important role in lung development and can potentially be beneficial in the prevention of BPD.

OBJECTIVE: The study aimed to compare the risk of BPD occurrence in preterm neonates supplemented with vitamin D or E versus those who did not get supplementation.

METHODS: The literature search was conducted for this systematic review by searching the PubMed, Scopus, and Web of Science databases up to December 2022. Randomized controlled trials involved administering vitamin D or E to preterm neonates and examining the occurrence of BPD. We excluded non-English articles, and articles with non-relevant and insufficient data. We used the Critical Appraisal Skills Programme (CASP) checklist to assess the quality of the included studies. We used Egger’s test to evaluate the risk of bias among the included studies. Heterogeneity was also assessed through Q-test and I2. We applied the random effect model for analysis. A P-value less than 0.05 was considered as significant. All the statistical analysis in the current study was performed using STATA 14. The Relative Risk (RR) was calculated as the effect size with 95% Confidence Interval (CI).

RESULTS: Three eligible studies seeking the role of vitamin D in the prevention of BPD were analysed. Meta-analysis revealed that receiving vitamin D supplementation can significantly reduce the risk of BPD in preterm infants (RR = 0.357, 95% CI: 0.189-0.675, I2 = 0.0%; p = 0.002). Similarly, for assessing the role of Vitamin E in the prevention of BPD, three eligible studies were analysed. Vitamin E supplementation was not found to play a significant role in the reduction of BPD (RR = 0.659, 95%CI = 0.243-1.786, I2 = 38.7%; p = 0.412).

CONCLUSION: Vitamin D supplementation could be beneficial in preventing BPD in preterm infants. However, evidence is not enough regarding vitamin E’s role in reducing the incidence of BPD in preterm infants.

ABSTRACT

BACKGROUND: Pancreatic Cancer (PC) is one of the most malignant tumors and highly invasive neoplasms around the world.

OBJECTIVE: This systematic review and meta-analysis aims to study the relationship between the use of renin-angiotensin-aldosterone system inhibitors and the incidence and mortality of PC.

METHODS: The electronic search was conducted systematically until October 10, 2023. in databases, including Scopus, Web of Science (WOS), PubMed/MEDLINE, Cochrane Library, and Embase. The required data were extracted from the articles and were analyzed by Stata 15 using statistical tests (Chi-square and I2), Forest plots, and publication bias tests (Begg’s and Egger’s tests).

RESULTS: A total of four studies (2011-2019; n=314,856) investigated the relationship between RAS antagonists and PC risk. No significant associations were found between angiotensin receptor blockers (ARBs) (OR=0.94, 95% CI: 0.77-1.14, p=0.513), angiotensin-converting enzyme inhibitors (ACEIs) (OR=0.96, 95% CI: 0.84-1.09, p=0.505), or combination therapy (ARBs + ACEIs) (OR=0.97, 95% CI: 0.87-1.09, p=0.627) and PC risk. Also, nine studies (2010-2023; n=20,483) examined the association between renin-angiotensin-aldosterone system inhibitors and PC mortality. Significant reductions in PC mortality were found for ARBs (OR=0.81, 95% CI: 0.66-0.98, p=0.032), ACEIs (OR=0.89, 95% CI: 0.80-0.99, p=0.038), and combination therapy (OR=0.83, 95% CI: 0.70-0.97, p=0.022). No evidence of publication bias was found in the study results.

CONCLUSION: In summary, while renin-angiotensin-aldosterone system inhibitors did not appear to impact PC risk, their use was associated with lower PC mortality based on this meta-analysis of the current evidence. More rigorous and well-designed studies are required to validate and support these findings.

ABSTRACT

BACKGROUND: Radial artery cardiac catheterization is a common diagnostic and interventional procedure for cardiovascular conditions. Pain and hemorrhage at the access site can cause patient discomfort and complications. This pilot study investigates the potential of local forearm heating to reduce pain and hemorrhage in patients undergoing radial artery cardiac catheterization.

METHODS: We enrolled 100 patients scheduled for radial artery cardiac catheterization and randomly assigned them to the heating or control group. The heating group received local forearm heating before sheath removal, while the control group did not. Pain intensity was assessed with a visual analog scale, and hemorrhage was measured by assessing ecchymosis or hematoma size at the catheterization site. Hemodynamic parameters were also monitored. Statistical analysis compared outcomes between the groups.

RESULTS: Patients who received local forearm heating had significantly lower pain intensity (4.15 ± 2.73) compared to the control group (5.84 ± 3.34) (P =.009). Hemodynamic parameters and the extent of hemorrhage at the catheterization site did not significantly differ between the heating and control groups (P >.05). No adverse effects related to forearm heating were reported.

CONCLUSION: Local forearm heating is a promising intervention to reduce pain intensity without increasing hemorrhage or affecting hemodynamic parameters during radial artery cardiac catheterization. This simple, noninvasive approach has the potential to enhance patient comfort and safety post procedure.

ABSTRACT

AIMS: To describe how workplace violence (WPV) is experienced by nurses in hospitals and community services and identify protective and risk factors.

METHODS: An online cross-sectional national study was conducted from January to April 2021 in Italy. Hospitals and community services were involved in the study. The survey combined the adapted and validated Italian version of the Violence in Emergency Nursing and Triage (VENT) questionnaire, which explores the episodes of WPV experienced during the previous 12 months, the Practice Environment Scale of the Nursing Work Index (PES-NWI) and some additional questions about staffing levels extracted from a previous RN4CAST study. Nurses working in all clinical settings and community services were invited to participate in the survey. Descriptive and inferential statistics were used for data analysis. We adhered to the STROBE reporting guidelines.

RESULTS: A total of 6079 nurses completed the survey, 32.4% (n = 1969) had experienced WPV in the previous 12 months, and 46% (n = 920) reported WPV only in the previous week. The most significant protective factors were nurses’ age, patients’ use of illegal substances, attitude of individual nurses and considering effective the organization’s procedures for preventing and managing episodes of violence. The most significant risk factors included workload, recognizing violence as an inevitable part of the job, patients’ cultural aspects and patients’ agitated behaviour. The frequency of WPV was significantly higher in certain areas, such as the emergency department and in mental health wards.

CONCLUSION: Workplace violence (WPV) against nurses is a very frequent and concerning issue, especially in hospitals and community services. Based on our findings, integrated and multimodal programmes for prevention and management of WPV are recommended. More attention and resources need to be allocated to reduce WPV by improving the quality of nurses’ workplace environment and implementing violence-free policies for hospitals.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Impact Workplace verbal and physical violence is a widespread phenomenon, both in hospital and community settings, and even during COVID-19 pandemic. This problem is exacerbated by the lack of effective reporting systems, fear of retaliation and the tendency to consider violence as an inevitable part of the job. The characteristics of professionals, patients, work environment and organizational factors are involved in the spread of workplace violence, determining its multifactorial nature. Integrated and multimodal programmes to prevent and manage of workplace violence are probably the only way to effectively counteract workplace violence against nurses. Healthcare policymakers, managers of hospital and community services need to proactively prevent and effectively manage and monitor episodes of violence. Nurses need to feel protected and safeguarded against any form of verbal or physical violence, to provide high-quality care in a totally safe environment.

PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.
