Despite neweffective medications, patients with spinal muscular atrophy types 1-3 can continue to have inadequate cough flows to prevent episodes of acute respiratory failure. Ventilator unweanable intubated patients are thought to require tracheostomy tubes. As a result, potentially beneficial medications may be discontinued and patients die despite receiving these medications. Three cases are presented of medically treated, physically strengthening children, with spinal muscular atrophy type 1. All three subsequently died or underwent tracheotomy. However, there is no evidence of extubation attempts to noninvasive ventilatory support settings or optimal mechanical insufflation-exsufflation despite this option being described to be over 98% successful for extubating unweanable medically untreated children with spinal muscular atrophy 1.

Background: Small infants experience a myriad of stimuli while in the Neonatal Intensive Care Unit (NICU), with many being painful or stressful experiences, although medically necessary. Purpose: To determine what is known about nonpharmacological developmental care interventions used in the NICU to mitigate procedural pain of infants born under 32 weeks gestation. Search/Strategy: Five electronic databases were searched: Medline, CINAHL, Scopus, Embase and the Cochrane Library. The inclusion criteria were as follows: experimental and nonexperimental studies from all publication years with infants born at less than 32 weeks gestational age; peer-reviewed research articles studying nonpharmacological interventions such as skin-to-skin care, facilitated tucking, nonnutritive sucking, hand hugs, and swaddling; and English language articles. Our search yielded 1435 articles. After the elimination of 736 duplicates, a further 570 were deemed irrelevant based on their abstract/titles. Then, 124 full-text articles were analyzed with our inclusion and exclusion criteria. Findings: Twenty-seven studies were reviewed. Sucrose, facilitated tucking, pacifier, skin-to-skin care, and human milk appeared to lessen pain experienced during heel sticks, suctioning, nasogastric tube insertions, and echocardiograms. All nonpharmacological interventions failed to prove efficacious to adequately manage pain during retinopathy of prematurity (ROP) examinations. Implications for Practice: Evidence review demonstrates that healthcare practitioners should use nonpharmacological measures to help prevent pain from day-to-day procedures in the NICU including heel sticks, nasogastric tube insertions, suctioning, echocardiograms, and subcutaneous injections. Implications for Research: Future research is necessary to better understand and measure how pain is manifested by very small premature infants. Specific research on mitigating the pain of examinations for retinopathy of prematurity is also needed. [ABSTRACT FROM AUTHOR]

Background: Artificial airways are essential in various clinical settings to maintain a patient's airway and provide necessary support for ventilation and oxygenation. These devices are commonly temporary and come in several types, each serving specific purposes. Understanding the indications, types, and proper care of artificial airways is crucial for health care professionals to ensure patients receive optimal care and prevent complications. Objective: This article aims to review the indications for using artificial airways and discuss the most commonly used types, including supraglottic airway devices, endotracheal tubes, tracheostomy tubes, and laryngectomy tubes. It also provides insights into the procedures involved in intubation and percutaneous tracheostomy and offers guidance on patient management, emphasizing assessment, oral care, suctioning, and humidification for patients with these airway devices. Conclusion: This article underscores the significance of understanding artificial airways, not just as a set of skills but as a commitment to patient welfare. Health care professionals who master the knowledge and care of these devices can significantly contribute to their patients' well-being and quality of life. [ABSTRACT FROM AUTHOR]

The controversial topic of oral feeding while on noninvasive ventilation remains at the forefront of preterm intensive care management. The intersection of pulmonary, neurologic, and gastrointestinal maturation coalesces at a postmenstrual age that requires changes in practices compared with those used in older infants. Various animal models in the past decades aimed to gain physiological knowledge of noninvasive ventilation effects on the suck–swallow–breathe coordination sequence. However, the preterm infant poses nuanced anatomic challenges. Although concerns for oral feeding while on noninvasive ventilation include aspiration risks and potential inpatient obstacles, there is evidence to support the feasibility, initiation, and progression of oral feedings while an infant is supported on high-flow nasal cannula and continuous positive airway pressure. There is evidence to support that this may accelerate attainment of oral feeding milestones and, thus, eventual hospital discharge. More recent multidisciplinary institutional protocols may provide cautious guidance on evaluation and algorithms to assess infants who may benefit from initiation and advancement of oral feeding versus awaiting further maturation.

Background: Drainage fluid amylase (DFA) is useful for predicting clinically relevant postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP). However, difference in optimal cutoff value of DFA for predicting CR-POPF between open DP (ODP) and laparoscopic DP (LDP) has not been investigated. This study aimed to identify the optimal cutoff values of DFA for predicting CR-POPF after ODP and LDP. Methods: Data for 294 patients (ODP, n = 127; LDP, n = 167) undergoing DP at Kobe University Hospital between 2010 and 2021 were reviewed. Propensity score matching was performed to minimize treatment selection bias. Receiver operating characteristic (ROC) analysis was performed to determine the optimal cutoff values of DFA for predicting CR-POPF for ODP and LDP. Logistic regression analysis for CR-POPF was performed to investigate the diagnostic value of DFA on postoperative day (POD) three with identified cutoff value. Results: In the matched cohort, CR-POPF rates were 24.7% and 7.9% after ODP and LDP, respectively. DFA on POD one was significantly lower after ODP than after LDP (2263 U/L vs 4243 U/L, p < 0.001), while the difference was not significant on POD three (543 U/L vs 1221 U/L, p = 0.171). ROC analysis revealed that the optimal cutoff value of DFA on POD one and three for predicting CR-POPF were different between ODP and LDP (ODP, 3697 U/L on POD one, 1114 U/L on POD three; LDP, 10564 U/L on POD one, 6020 U/L on POD three). Multivariate analysis showed that DFA on POD three with identified cutoff value was the independent predictor for CR-POPF both for ODP and LDP. Conclusions: DFA on POD three is an independent predictor for CR-POPF after both ODP and LDP. However, the optimal cutoff value for it is significantly higher after LDP than after ODP. Optimal threshold of DFA for drain removal may be different between ODP and LDP. [ABSTRACT FROM AUTHOR]

We present the case of a newborn infant who developed pneumothorax. The pneumothorax was managed by providing 100% oxygen (O2) with the "nitrogen washout" concept. Post- hyperoxia treatment, the infant developed signs of pulmonary hypertension, evidenced by an echocardiogram. He was successfully treated with inhaled nitric oxide. The primary purpose of this report is to highlight the point that caution should be exercised in treating stable pneumothorax with 100% O2. [ABSTRACT FROM AUTHOR]

Background: The effective therapeutic approach is still an unmet need for patients diagnosed with both lung cancer and interstitial lung disease (ILD). This is primarily due to the possible risk of ILD exacerbation caused by surgery or radiotherapy. The current study aimed to investigate the efficacy and safety of local ablative therapy (LAT) for this specific population. Methods: Consecutive patients with non-small cell lung cancer (NSCLC) and ILD who received LAT between January 2018 and August 2022 were enrolled, and propensity score matching (PSM) was utilized to match the non-ILD group. The primary endpoint was recurrence-free survival (RFS), and secondary endpoints included overall survival (OS), adverse events (AEs) and hospital length of stay (HLOS). Results: The PSM algorithm yielded matched pairs in the ILD group (n = 25) and non-ILD group (n = 72) at a ratio of 1:3. There were no statistically significant differences in RFS (median 16.4 vs. 18 months; HR = 1.452, p = 0.259) and OS (median: not reached vs. 47.9 months; HR = 1.096, p = 0.884) between the two groups. Meanwhile, no acute exacerbation of ILD was observed in the ILD group. However, the incidence of pneumothorax, especially pneumothorax requiring chest tube drainage, was significantly higher (36.0% vs. 11.2%, p = 0.005) among patients with NSCLC and co-existing ILD, which resulted in longer HLOS (p = 0.045). Conclusion: Although ILD was associated with a higher incidence of pneumothorax, the efficacy of LAT for NSCLC patients with ILD was comparable to those without ILD, suggesting that LAT might be a reliable and effective treatment option for this population, particularly in the early stage.

There is much controversy about the application of abdominal irrigation in the prevention of wound infection (WI) and intra‐abdominal abscess (IAA) in the postoperative period. Therefore, we performed a meta‐analysis of the effect of suctioning and lavage on appendectomy to assess the efficacy of either suctioning or lavage. Data were collected and estimated with RevMan 5.3 software. Based on our research, we found 563 publications in our database, and we eventually chose seven of them to analyse. The main results were IAA after the operation and WI. Inclusion criteria were clinical trials of an appendectomy with suctioning or lavage. In the end, seven trials were chosen to meet the eligibility criteria, and the majority were retrospective. The results of seven studies showed that there was no statistically significant difference between abdominal lavage and suctioning treatment for post‐operative WI (OR, 1.82; 95% CI, 0.40, 2.61; p = 0.96); There was no statistically significant difference between the two groups in the risk of postoperative abdominal abscess after operation (OR, 1.16; 95% CI, 0.71, 1.89; p = 0.56). No evidence has been found that the use of abdominal lavage in the treatment of postoperative infectious complications after appendectomy is superior to aspiration. [ABSTRACT FROM AUTHOR]

Introduction: Improved survival rates in extremely low birth weight (ELBW) neonates require smaller instruments and newer techniques to manage atelectasis in neonates on mechanical ventilation. Case presentation: A chronically ventilated 23-week gestational age neonate weighing 465g developed worsening respiratory distress on day of life 17. X-rays showed complete opacification of the left lung. Flexible fiberoptic bronchoscopy (FFB) was performed with a 2.2 mm bronchoscope through the endotracheal tube (ETT), where an occlusive mucus plug was visualized in the left mainstem bronchus. Due to the lack of suction capability with this bronchoscope and inability to pass a larger one, the bronchoscope was positioned proximal to the mucous plug, the ETT was advanced over the bronchoscope, thereby selectively intubating the left mainstem bronchus, the bronchoscope was removed, an 8Fr suction catheter was inserted, and suction was applied resulting in successfully removal of the mucous plug. Immediate clinical improvement and reaeration of the left lung were noted. Conclusion: This case introduces a novel FFB technique to manage left lung atelectasis in critically ill ELBW neonates.

Objective: Auricular pseudocysts are rare, painless, benign intracartilaginous cysts of the auricle that are not lined by epithelium and have no known aetiology. Method: This was a prospective study conducted in an ENT department from January 2020 to June 2022. In 21 patients, complete aspiration of the pseudocyst with enhanced negative drainage was performed. They were followed for a minimum of six months. Results: All patients completely responded to the negative drainage treatment. No cases of recurrence or obvious deformities were observed. Conclusion: Aspiration with intensified negative drainage was associated with a positive response in patients with auricular pseudocysts. Complete resolution of the swelling can be achieved without any serious complications. Thus, it appears to be a simple and effective method for managing the condition. [ABSTRACT FROM AUTHOR]

The methodology of efficiency analysis of turbulent flow modification by making permeable sections in the streamlined wing surface with the aim to reduce aerodynamic drag is the principal subject of the presented research. The numerical analysis of the effect of laterally and longitudinally located permeable sections on boundary-layer properties showed the following flow features: (1) the most effective place for permeable surface is an upwind side of the wing; (2) multi-sectional blowing can simply be organised as non-uniform (especially in the case of laterally arranged permeable sections) that brings additional flexibility to change the blowing intensity depending on flight mode and, first of all, on angle of attack; and (3) arrays of longitudinal permeable sections allow to intensify turbulent vortical structures exchange in the lateral direction and improve flow stability to stall. Moreover, due to creating the regular anisotropy of the boundary layer in the lateral direction, this modified blowing technique can potentially have some synergistic properties, which can give the additional benefit. All these effects are too delicate and their experimental study cannot be performed with the use of directed measurements of aerodynamic forces. The comparison of the obtained flow properties with the corresponding experimental data demonstrates an appropriate level of agreement. [ABSTRACT FROM AUTHOR]

This study investigates the clinical effects of the novel Traditional Chinese Medicine (TCM) topical wash used in combination with negative pressure irrigation and tadalafil for the treatment of vascular erectile dysfunction. Eighty-seven patients with vascular erectile dysfunction were divided into an observation group and a control group. The observation group was administered negative pressure irrigation (TCM) in combination with oral tadalafil for four weeks, and the control group was administered oral tadalafil for four weeks. The observation group included 21 patients with arterial erectile dysfunction and 22 with intravenous erectile dysfunction. After treatment, IIEF-5, EHS, GAD scores, PSV, EDV and RI in observation group were improved compared with those before treatment (P = 0.000, 0.000, 0.000, L0.000/R0.000, L0.000/R0.000, L0.003/R0.000). Erectile function (IIEF-5, EHS) was significantly improved compared with the control group (P = 0.008, 0.002). In the observation group, there were 21 cases of arterial erectile dysfunction and 22 cases of intravenous erectile dysfunction. After treatment, PSV of arterial ED improved significantly (P = L0.000/R0.000), but EDV did not decrease significantly (P = L0.084/R 0.098). In patients with venous ED, PSV increased (P = L0.026/R0.032) and EDV decreased significantly (P = L0.000/R0.000). These findings suggest that TCM negative pressure lavage combined with tadalafil improves the blood supply of the penile artery, relaxes smooth muscle, and improves the closing mechanism of venous vessels in patients with vascular erectile dysfunction, ultimately improving the erectile function.

It is difficult to avoid deep surgical site infection after spinal surgery. Debridement combined with closed suction irrigation (CSI) and other treatment methods lead to greater trauma and lower satisfaction. We developed a new method for the treatment of SSI, which has the advantages of less invasiveness and lower cost. The cohort of this retrospective study comprised 26 patients with SSI after undergoing spinal surgery in our hospital from August 2017 to March 2022. The patients were divided into CSI and microtube drainage group according to treatment methods. The durations of antibiotic use and hospital stay, hospitalization costs, and functional scores during follow‐up were compared between the two groups. The only baseline characteristic that differed between the two groups was sex. Infection was controlled in both groups and there were no recurrences during follow‐up. However, the length of hospital stay after the first operation and the total length of stay were significantly greater in the CSI group. Hospitalization costs and antibiotic costs were significantly higher in the CSI group. Additionally, the duration of intravenous antibiotic use was significantly longer in the CSI group. Both the CSI and microtube drainage groups had significantly improved of Short Form Health Survey (SF‐36) scores 6 months postoperatively. However, 3 months postoperatively, SF‐36 scores were significantly lower in the CSI group. Compared with debridement followed by CSI, percutaneous micro‐drainage tube irrigation combined with high negative pressure tube drainage is a more efficient and economical means of treating SSI after spinal surgery.

When noninvasive interventions such as chest physiotherapy fail, then more aggressive interventions for airway secretion clearance with nasotracheal airway suctioning may be required. Clinicians however have to insert the nasotracheal suction catheter "blindly" and the success of being able to trigger a cough and pass through the vocal folds with a suction catheter is low. The patient, a 48-year-old male underwent a heart and lung transplant. Following extubation, the patient developed secretion retention with a weak ineffective cough and swallow and required physiotherapy interventions with frequent "blind" passes of nasotracheal suctioning. The patient required nasotracheal suction with frequent multiple failed attempts before successful passage of the suction catheter to trigger a cough reflex and clear secretions. A combined physiotherapist and speech and language therapist intervention during fiberoptic endoscopic evaluation of swallow (FEES) was recorded to both evaluate swallow and passage of the suction catheter. The video illustrated the successful passage of a suctioning catheter through the vocal folds leading to an effective cough and airway clearance. We present a case report demonstrating that it is feasible to visualize the upper airways during nasotracheal suctioning as an objective means to guide the more accurate successful insertion of the suction catheter past the vocal folds. Rather than "blind" placement of nasotracheal suction catheters visualization using transnasal laryngoscopy should be useful to increase chances of passing through the vocal folds.

Objective: The study aimed to compare the risk factors, treatment strategies, and early outcomes of symptomatic neonatal pneumothorax (NP) between preterm and term newborns. Materials and Methods: This retrospective cross-sectional study was conducted in a neonatal intensive care unit between 2015 and 2022, consisting of hospitalized neonates with symptomatic NP. The cases were divided into three groups according to their gestational ages: <340/7 (group 1), 340/7-366/7 (group 2), and ≥370/7 weeks (group 3). Risk factors, treatment strategies, and mortality rates of the study groups were compared using Kruskal–Wallis analysis. Results: Fifty-nine infants with a diagnosis of symptomatic NP were included in the study. The number of participants was as follows: 25 (42.3%) in group 1, 18 (30.5%) in group 2, and 16 (27.1%) in group 3. The need of delivery room (DR) resuscitation was significantly higher in group 1 (40%, P = .003). The surfactant administration rate was significantly higher in group 1 when compared to group 2 and group 3 (68% vs. 22% and 19%, respectively), P < .001. Similarly, the invasive mechanical ventilation percentage was significantly higher in group 1 than group 2 and group 3, P = .014. However, compared to group 3 (63%), the percentage of chest drain insertion (CDI) need was significantly higher in group 1 (96%) and group 2 (89%) (P = .014). Conclusion: Exposure to DR resuscitation and the need for surfactant are the most common risk factors for NP in preterm infants. Although oxygen and/or needle aspiration treatments are less invasive in symptomatic NP, the improvement rate without CDI is very low in preterm infants born before 34 weeks of gestational age.

The infratemporal fossa (IF) is an important anatomical space that carries vital neurovascular structures within it. The formation of an abscess in the IF, particularly of odontogenic aetiology, is rare. It can pose a diagnostic challenge due its uncommon presentation and can be life-threatening with delayed treatment. We present an unusual case of an IF abscess in an otherwise healthy female patient. Due to the rising difficulty accessing emergency NHS dental services, the untimely diagnosis and management of odontogenic infections may lead to similar scenarios. CPD/Clinical Relevance: It is important that clinicians have good knowledge of the anatomy of fascial spaces and be aware of signs and symptoms of spreading infections. [ABSTRACT FROM AUTHOR]

Background: Stress exposure in the neonatal intensive care unit (NICU) is associated with poor outcomes in preterm infants. However, factors predicting subsequent NICU stress exposure have not been identified. Purpose: To characterize NICU stressors experienced by preterm infants during the first 2 weeks of life and identify demographic, perinatal, and institutional variables associated with stress exposure. Methods: A secondary analysis of data from a nonexperimental, prospective study was conducted using data from 60 very preterm infants born 28 to 31 weeks gestational age. Stress exposures during the first 2 weeks of life, operationalized as number of invasive procedures, were characterized by type and quantity for each infant using data extracted from electronic health records. Associations between number of invasive procedures and demographic, perinatal, or institutional variables were analyzed using linear regressions with robust standard errors. Results: Preterm infants experienced, on average, 98 (SD = 41.8) invasive procedures. Of these invasive procedures, nasal and/or oral suctioning episodes (58.1%), followed by skin-breaking procedures (32.6%), were most frequent. Differences in the number of invasive procedures were found for maternal race; infants born to Black mothers experienced fewer total invasive procedures than infants born to White mothers. The number of invasive procedures also varied across NICUs. Implications for Practice and Research: Preterm infant stress exposure differed by maternal race and NICU, consistent with research findings of differential treatment of diverse infants. Further research is needed to understand the reasons for these differences and to identify best practices to standardize neonatal care. [ABSTRACT FROM AUTHOR]

Objectives: This study investigated the influence of tooth position within the quadrant and method of tooth preparation on aerosol and splatter reduction by suction techniques. Materials and methods: Using four suction techniques, tooth preparation was done using fast handpiece and combined air and water spray on tooth #28, #29 and #30. Splatter, aerosol and total sound generated were recorded. Two-way analysis of variance and posthoc pairwise comparisons compared amount of aerosol, spatter and total sound among suction techniques, tooth location and method of preparation. Results: There were statistically significant more splatter (P < 0.000) for tooth preparation with air and water spray compared with high-speed handpiece for all suction techniques, but no significant difference in aerosol and total sound (P > 0.05) was recorded. A significant reduction in environmental splatter during tooth preparation of the distal tooth #30 by all suction methods was observed compared with tooth #28. However, there was no significant difference in the amount of face shield, chest, right arm and left arm splatter, aerosol and total sound based on tooth location. Overall, the prototype suction device had statistically significant less environmental splatter (P < 0.001) and aerosol (P = 0.004) than the conventional HVE device. Conclusions: The method of tooth preparation affected splatter mitigation by suction techniques but had no influence on aerosol mitigation. Mitigation of environmental splatter by suction techniques was affected by tooth position within the arch. The prototype suction device reduced environmental spatter and aerosol more than the conventional HVE device. Clinical Significance: The variations observed in aerosol and splatter mitigation based on tooth preparation methods and tooth location provides evidence for adjunctive means of reducing risk of direct transmission of infection in the dental practice such as combining strategies of protective equipment, improved room ventilation and use of air filtration system.

The current study aimed to evaluate the dispersal of solution and microbes (aerosol) in the clinical environment during treatment with Low‐frequency contact ultrasonic debridement (LFCUD) with or without suction attachment in patients with diabetic foot ulcers (DFUs). We performed 20 treatments in 10 patients divided into two groups to receive the proposed LFCUD modalities. We measured the microbial load of the environment pre‐treatment (sample M1), during treatment with each LFCUD modality (sample M2) and post‐treatment (sample M3). The use of LFCUD debridement without a suction attachment results in significantly higher immediate contamination of the clinic environment than the suction attachment, particularly during the procedure (1.70 ± 0.98 log 10 CFU/mL versus 0.77 ± 0.85 log 10 CFU/mL, p = 0.035). When suction is not applied, there are statistically significant differences depending on whether the DFUs are neuropathic or neuroischemic, finding a greater number of microorganisms with high loads in neuropathic DFUs. We found a statistically significant positive correlation between wound area (r = 0.450, p = 0.047) and TBI (r = 0.651, p = 0.006) with the bacterial load during the LFCUD. Based on our results, we recommend using the personal protective equipment required to protect staff members and patients during treatment with LFCUD and using a suction attachment where clinically possible to reduce clinic environmental pollution, especially in neuropathic DFUs and those with larger areas.

Peritoneal dialysis (PD) is an important modality of renal replacement therapy (RRT) in children in the acute setting. Despite the favorable outcomes of RRT, PD catheter insertions have various complications that may be related either to variations in procedural technique or infections. We report a case of a child with massive retroperitoneal and intra-abdominal bleeding secondary to injury to the inferior epigastric arterial arcade, near the urinary bladder following the insertion of a PD catheter.

Summary: Semaglutide is a new weight loss treatment that has received substantial media attention in recent years. Anaesthetists must be aware of a potentially dangerous side effect of the drug: decreased gastric emptying. This is caused by effects on gastric smooth muscle, mediated by the vagal afferent nerves. This is especially relevant in the peri‐operative setting where pulmonary aspiration of gastric contents is a recognised complication. Here, we report two cases of peri‐operative regurgitation of gastric contents in patients taking semaglutide. A patient taking semaglutide may have a full stomach despite compliance with routine pre‐operative fasting guidelines. We consider how to manage patients receiving glucagon‐like peptide‐1 agonist therapy in the peri‐operative period, including identifying those at high risk of regurgitation. Precautions such as rapid sequence induction and tracheal intubation can be used, but gastric ultrasound may also be useful in the pre‐operative environment to help identify patients at high risk of aspiration.

Backgrounds: Dental procedures involving drilling and grinding can produce a significant amount of suspended aerosol particles (PM) and bioaerosols. This study aims to analyze the size and concentration of aerosol particles generated during drilling and to investigate the effectiveness of two air exchange systems, namely forceful suction (FS) and air disinfection machines (DM), in removing PM. Methods: For this study, 100 extracted permanent teeth were collected and divided into three groups: without suction (n = 50), suction with forceful suction (n = 25), and suction with air disinfection machines (n = 25). The removal rate of suspended aerosol particles was analyzed using particle counters and air data multimeter. Results: When drilling and grinding were performed without vacuum, 0.75% of the aerosol particles generated were PM2.5-10, 78.25% of total suspended aerosol particles (TSP) were PM2.5, and 98.68% of TSP were PM1. The nanoanalyzer measurements revealed that the aerodynamic diameter of most aerosol particles was below 60 nm, with an average particle diameter of 52.61 nm and an average concentration of 2.6*1011 ultrafine aerosol particles. The air change per hour (ACH) was significantly lower in the air disinfection machines group compared to the forceful suction group. Additionally, the number of aerosol particles and mass concentration was significantly lower in the air disinfection machines group compared to the forceful suction group in terms of PM2.5 levels. However, the forceful suction group also reduced the mass concentration in PM10 level than the air disinfection machines group. Conclusion: In conclusion, the air exchange system can reduce the aerosol particles generated during drilling and grinding. Comparing the two air exchange systems, it was found that the air disinfection machines group reduces the number of aerosol particles and mass concentration in PM2.5 levels, while the forceful suction group reduces the mass concentration in PM10 level.

Introduction: Epicardial ablation is an important approach in the management of patients with complex ventricular arrhythmias. Irrigated ablation catheters present a challenge in this potential space due to fluid accumulation that can cause hemodynamic compromise, requiring frequent manual fluid aspiration. In this series, we report our initial experience with the use of a dry suction water seal system for pericardial fluid management during epicardial ablation. Methods: Consecutive patients undergoing epicardial ventricular tachycardia (VT) ablation at a single center were included. All patients underwent epicardial access via a subxiphoid approach with a single operator. A deflectable sheath was advanced into the pericardial space, and the side port was attached to a dry suction water seal system attached to wall suction at −20 mmHg. Procedural information including patient characteristics, outcomes, and adverse events. After a period of initial experience, pericardial fluid infusion and aspiration volumes were recorded. Results: Eleven patients were included in this series. All patients underwent epicardial ablation with complete success achieved in 8 of the 11 patients and partial success in the remaining patients. Pericardial fluid intake ranging from 485 to 3050 mL with aspiration of 350–3050 mL using the dry suction water seal system. No adverse events occurred. Conclusion: Dry suction water seal drainage systems can provide a safe strategy for efficient pericardial fluid management during epicardial VT ablation, potentially shortening procedure duration.

Suctioning of newborns immediately after birth, as part of delivery room resuscitation, is only recommended if the airway is obstructed. The aim of this study was to describe the use of suctioning during newborn resuscitation among survivors versus those who died within 3 days and potential suction-related heart rate responses and associations to newborn characteristics. This was a retrospective observational study from July 2013 to July 2016 in a referral hospital in rural Tanzania. Research assistants observed and documented all deliveries, newborn resuscitations were video-recorded, and newborn heart rates were captured with a dry-electrode electrocardiogram. Liveborn infants ≥34 weeks gestation who received ventilation and with complete datasets were eligible. All 30 newborns who died were included, and a total of 46 survivors were selected as controls. Videos were annotated and heart rate patterns were observed before and after the suction events. Suctioning was performed more frequently than recommended. No differences were found in suctioning characteristics between newborns who died versus those who survived. In 13% of suction events, a significant heart rate change (i.e., arrhythmia or brief/sustained >15% fall in heart rate) was observed in relation to suctioning. This represents a potential additional harm to already depressed newborns undergoing resuscitation. [ABSTRACT FROM AUTHOR]

Pressure injury often seriously affects the life quality of aged patients, especially the long‐term bedridden casualties. Widely adopted by different disciplines, negative pressure suction has its role in pressure injury. Microskin implantation has been demonstrated powerful in increasing the expansion ratio of donor area‐derived skin and accelerating wound healing by forming "skin islands". The study was designed to evaluate the efficacy and safety of additional use of bedside microskin implantation in the palliative care of pressure injury of aged patients who cannot tolerate surgical treatment as a supplement for standard negative pressure suction. An open‐label within‐patient RCT was conducted in aged patients with pressure injury. Sixteen patients were enrolled. After granulation tissues formed, half of a pressure injury was randomised to receive the negative pressure suction as the control group, and the other half exposed to additional bedside microskin implantation as the experimental group. Efficacy was evaluated within 1 month after treatment, and the primary endpoints included the wound healing rate and pressure ulcer scale for healing (PUSH) scores. The secondary outcomes included survival rate of implanted microskin, pain intensity assessment, satisfaction surveys from patients or their family, and pressure ulcer healing complications. Sixteen patients completed the study. After 14 days of operation, 5.63 ± 1.78 out of 10 pieces of implanted microskin survived and formed neonatal epithelium. The wound healing rates of the control group and the experimental group at 1 month were (26.17 ± 9.03%) and (35.95 ± 16.02%), respectively (P <.01). The mean PUSH score before the surgery was 12.38 ± 2.23. At 1 month after surgery, the mean difference of PUSH score from baseline was 2.13 ± 0.96 in the control group and 2.81 ± 0.83 in the experimental group (P <.01). The treatment of microskin implantation did not cause additional pain or complications to the patients. Accompanied by a better ulcer status, the majority of patients or their guardians have a high degree of acceptance towards the microskin implantation. Bedside microskin implantation could accelerate wound healing with lower PUSH scores. As a complementary palliative treatment, supplementary microskin implantation is effective and well tolerated.

Background: Many studies on closed suction drainage (CSD) in primary total hip arthroplasty (THA) have demonstrated that it has no definite benefit. However, evidence of the clinical benefits of CSD in revision THA has not yet been established. Therefore, this retrospective study aimed to investigate the benefits of CSD in revision THA. Materials and Methods: We reviewed 107 hips of patients who underwent revision THA between June 2014 and May 2022, excluding cases of fracture and infection. We compared perioperative blood test results, calculated total blood loss (TBL), and postoperative complications, including allogenic blood transfusion (ABT), wound complications, and deep venous thrombosis (DVT), between the groups with and without CSD. Propensity score matching was conducted to balance patients' demographics and surgical factors. Results: ABT, wound complications, and DVT were observed in 10.3% (n = 11), 5.6% (six), and 5.6% (six) of patients, respectively. There were no significant differences in ABT, calculated TBL, wound complications, and DVT between all patients and propensity score-matched patients with or without CSD. The calculated TBL was approximately 1200 mL and showed no significant difference between the two groups in the matched cohort (p = 0.40) but tended to have a greater volume in the drain group than in the non-drain group. Conclusion: The routine use of CSD in revision THA for aseptic loosening may not be useful in clinical practice. [ABSTRACT FROM AUTHOR]

Significance statement: A 53-year-old man with left facial pain was referred to our hospital. Nasal endoscopy revealed a purulent discharge at the left middle meatus and bulging of the uncinate process. Computed tomography demonstrated that the dental implant was blocking the left maxillary ostium. Functional endoscopic sinus surgery was performed under general anesthesia. After removal of the uncinate process, a yellowish purulent discharge in the left maxillary sinus discharged from the maxillary sinus. The presence of the dental implant in the infundibulum shows the direction of mucociliary clearance from the nasal sinus. This case indicates how our sinus clears a foreign body, and the direction in which the foreign body is removed. [ABSTRACT FROM AUTHOR]

Background: Data regarding the risk of infection related to reusable bronchoscopes, the global drive toward disposable technology and the COVID-19 pandemic have led to an increase in the use and production of single use or disposable bronchoscopes. An in-depth comparison of all available devices has not been published. Methods: A benchtop comparison of the Ambu®aScopeTM, Boston Scientific® EXALTTM Model B, the Surgical Company Broncoflex© Vortex, Pentax® Medical ONE Pulmo™, and Vathin® H-SteriscopeTM (all 2.8 mm inner dimension other than the Pentax single-use flexible bronchoscope (3 mm)) was undertaken including measurement of maximal flexion and extension angles, thumb force required and suction with and without biopsy forceps. Thereafter, preclinical assessment was performed with data collected including experience, gender, hand size, and scope preference. Results: The Vathin single-use flexible bronchoscope had the biggest range of tip movement from flexion to extension with and without forceps. The Boston single-use flexible bronchoscope required the maximal thumb force but had the least reduction of tip movement with forceps. The Boston single-use flexible bronchoscope significantly outperformed all other scopes including the standard Pentax scope and was the only scope capable of suctioning pseudo-mucus around the forceps. Although there was no significant difference in preference in the overall group, females and those with smaller hand size preferred the Pentax and males the Broncoflex single-use flexible bronchoscope. Conclusions: Currently available single-use flexible bronchoscopes differ in several factors other than scope sizes and monitor including suction, turning envelope, and handle size. Performance in the clinical setting will be key to their success. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Many interventions in bronchiolitis are low-value or poorly studied. Inpatient bronchiolitis management is multidisciplinary, with varying degrees of registered nurse (RN) and respiratory therapist (RT) autonomy. Understanding the perceived benefit of interventions for frontline health care personnel may facilitate deimplementation efforts. Our objective was to examine perceptions surrounding the benefit of common inpatient bronchiolitis interventions. METHODS: We conducted a cross-sectional survey of inpatient pediatric RNs, RTs, and physicians/licensed practitioners (P/LPs) (eg, advanced-practice practitioners) from May to December of 2021 at 9 university-affiliated and 2 community hospitals. A clinical vignette preceded a series of inpatient bronchiolitis management questions. RESULTS: A total of 331 surveys were analyzed with a completion rate of 71.9%: 76.5% for RNs, 57.4% for RTs, and 71.2% for P/LPs. Approximately 54% of RNs and 45% of RTs compared with 2% of P/LPs believe albuterol would be "extremely or somewhat likely" to improve work of breathing (P < .001). Similarly, 52% of RNs, 32% of RTs, and 23% of P/LPs thought initiating or escalating oxygen in the absence of hypoxemia was likely to improve work of breathing (P < .001). Similar differences in perceived benefit were observed for steroids, nebulized hypertonic saline, and deep suctioning, but not superficial nasal suctioning. Hospital type (community versus university-affiliated) did not impact the magnitude of these differences. CONCLUSIONS: Variation exists in the perceived benefit of several low-value or poorly studied bronchiolitis interventions among health care personnel, with RNs/RTs generally perceiving higher benefit. Deimplementation, educational, and quality improvement efforts should be designed with an interprofessional framework. [ABSTRACT FROM AUTHOR]

The possibility of using the vortex effect in aspirators, a category of medical equipment, was studied. A block diagram of the device created is presented, along with results from trial experiments. The possibility of increasing the technological efficiency of the device by automating the process of selecting and maintaining the required pressure, as well as optimizing the performance of the Ranque–Hilsch vortex tube used, is demonstrated.

Bronchiolitis and status asthmaticus are common diagnoses encountered in the pediatric intensive care unit setting with overlapping clinical manifestations that can create perplexity in treatment following hospital admission. While there are clear first-line therapies for each of these medical conditions, the use of adjunct therapies has been inconsistent and more dependent on provider preference at times. In this review, a brief introduction to the epidemiology, clinical presentation, and diagnosis allows for a review of proposed therapies to highlight the distinctions between these two entities.

Aim: The aim of this study is to determine the effects of milking and suction methods on maintaining drain patency following cardiac surgery in paediatric patients. Methods: This was a randomized controlled trial. The patients were assigned to three groups (suction method, milking method, and control group) between July 2018 and December 2019. Results: The most frequent medical diagnoses were tetralogy of Fallot (34.4%, n = 31) and ventricular septal defect (14.4%, n = 13). Heart rate may increase unless a method was chosen to maintain drain patency (F: 4.450, p = 0.003); suction (F: 0.528 p = 0.781) and milking (F: 2.281 p = 0.070) methods did not significantly increase the heart rate. The use of a manipulation method for maintaining drain patency maintained stability of the blood pressure values and did not affect haemodynamic stability, oxygen saturation, and body temperature. There was no statistically significant difference within and among the groups (p > 0.05) in relation to the volume of bleeding between admission until the sixth hour, although there was greater bleeding with the milking method (2.67 ± 15.30 ml) and less bleeding (−5.00 ± 23.30) with the suction method. Conclusion: The milking and suction methods used to maintain drain patency can be employed and will assist with maintaining the stability of the patient within the first critical 6 h. Further studies need to be conducted in order to clarify that the recommendations can be generalized to all children with congenital heart disease. Summary statement: What is already known about this topic? Manipulation methods are employed to prevent drain blockage after cardiac surgery.Milking and suction methods are frequently used.There is a limited amount of research‐based evidence to support nursing management for these methods of preventing blockage in chest and mediastinal drains. What this paper adds? Manipulation methods could be used, especially for patients to maintain stability in the first critical six hours after surgery, and they do not harm the hemodynamic process.The milking method used to maintain drain patency in paediatric patients after cardiac surgery can be considered less preferred because it causes an increase in the amount of bleedingThe suction method can be preferred because it reduces the amount of bleeding in the critical early post‐operative period. The implication of this paper: Findings can support decision‐making over the method to be used to maintain drain patency, decided by the treating team in a multidisciplinary manner.

Objective: To establish the relationship between endoscope temperatures and luminosity with a variety of light source types, endoscope ages, endoscope sizes, angles and operative distance in transcanal endoscopic ear surgery. Methods: Transcanal endoscopic ear surgery was simulated in an operating theatre using 7 mm plastic suction tubing coated in insulating tape. An ATP ET-959 thermometer was used to record temperatures, and a Trotec BF06 lux meter was used to measure luminosity. Luminosity and temperature recordings were taken at 0 mm and 5 mm from the endoscope tip. Results: Thermal energy transfer from operating endoscopes is greatest when: the light intensity is high, there is a light-emitting diode light source and the endoscope is touching the surface. Additionally, larger-diameter endoscopes, angled endoscopes and new endoscopes generated greater heat. Conclusion: It is recommended that operative light intensity is maintained at the lowest level possible, and that the surgeon avoids contact between patient tissues and the endoscope tip.

Background: With the advent of the Fédération Internationale de Football Association (FIFA) World Cup 2022 in Qatar, all healthcare systems were gearing up for an influx of patients. The Hamad Medical Corporation Ambulance Service (HMCAS) has also refined its patient supply chain (SC) processes to improve ambulance turnaround times (ATATs) at the emergency departments (EDs). International ambulance services (AS) are complex, and these ambulances are equipped with approximately 500 individual items, which include various types of medical consumables and equipment used during emergencies. By organizing individual medical items into stock units called "pre-packs", according to the needs of the patients and type of clinical interventions, the inventory or stock-taking time of items stored in ambulances can be significantly reduced. Implementing reduced inventory lists of items and standardized pre-pack storage across the ambulance fleet has significantly improved the efficiency and accuracy of ambulance checking, restocking, and recovery time, improving overall ATAT at the ED. Aim: This study evaluates the staff's perceived impact of modular pre-pack kits on ambulance restocking processes and ED ATAT. Methods: In this cross-sectional study, a fit-for-purpose survey was designed and distributed to all operational staff at HMCAS. The survey aims to assess HMCAS staff's opinions about the implemented LEAN pre-pack system. Cronbach's alpha was calculated to assess the reliability of the survey. The Mann-Whitney U-test was conducted to compare if there was a difference between the group's opinions. The Shewhart control chart was created to monitor the impact of the implemented intervention on the ATAT at the ED. IBM-SPSS® (Statistical Package for Social Sciences) Version 26 was utilized for data analysis. Results: A group of 287 employees with different backgrounds participated and completed the survey. The Cronbach's alpha was equal to 0.739, indicating a satisfactory level of reliability of the Mann-Whitney U-test. The descriptive analysis and the Shewhart chart revealed that most staff found that the pre-pack concept helped improve LEAN restocking processes, access to clinical applications, and ambulance checks. Overall, this concept matched the international benchmarks for turnaround time. Conclusion: The pre-pack concept promoted easy and quick processing of clinical applications, restocking procedures, and ambulance checks, and this positively impacted the ATAT at the ED. Further, it improved responses to emergency calls and enhanced access to effective care for patients. This approach also simplified the tasks above when many locum staff is employed on a short-term basis to cover mega-events such as the FIFA World Cup. [ABSTRACT FROM AUTHOR]

Background: Open laparotomy with gastroenterological surgery is a surgical procedure results in a relatively high rate (about 10% or more) of incisional surgical site infection (SSI). To reduce incisional SSI after open laparotomy, mechanical preventors, such as subcutaneous wound drainage or negative-pressure wound therapy (NPWT), have been tried; however, conclusive results have not been obtained. This study evaluated the prevention of incisional SSI by first subfascial closed suction drainage after open laparotomy. Methods: A total of 453 consecutive patients who underwent open laparotomy with gastroenterological surgery by one surgeon in one hospital (between August 1, 2011, and August 31, 2022) was investigated. Same absorbable threads and ring drapes were used in this period. Subfascial drainage was used in consecutive 250 patients in the later period (between January 1, 2016, and August 31, 2022). The incidences of SSIs in the subfascial drainage group were compared to those of in the no subfascial drainage group. Results: (a) No incisional SSI (superficial and deep) occurred in the subfascial drainage group (superficial = 0% [0/250] and deep = 0% [0/250]). As a result, incidences of incisional SSI of the subfascial drainage group were significantly lower than those of the no subfascial drainage group (superficial = 8.9% [18/203]; deep = 3.4% [7/203]) (p < 0.001 and p = 0.003, respectively). (b) Four out of seven deep incisional SSI patients in the no subfascial drainage group underwent debridement and re-suture under lumbar or general anesthesia. (c) There was no significant difference in the incidences of organ/space SSI of the two groups (3.4% [7/203] in the no subfascial drainage group and 5.2% [13/250] in the subfascial drainage group) (P = 0.491). Conclusion: Subfascial drainage was associated with no incisional SSI after open laparotomy with gastroenterological surgery. [ABSTRACT FROM AUTHOR]

Introduction: The use of wound drainage following total knee arthroplasty (TKA) remains controversial. The purpose of this study was to evaluate the impact of suction drainage on early postoperative outcomes in patients who underwent TKA with concomitant administration of intravenous tranexamic acid (TXA). Method: One hundred forty-six patients undergoing primary TKA with systematic intravenous TXA were prospectively selected and randomly divided into two groups. The first "Study group" (n = 67) received no suction drain and the second "Control" group (n = 79) had a suction drain. Perioperative hemoglobin levels, blood loss, complications, and length of hospital stay were assessed in both groups. Preoperative and postoperative range of motion and Knee Injury and Osteoarthritis Outcome Scores (KOOS) were also compared at a 6-week follow-up. Results: The study group was found to have higher hemoglobin levels preoperatively and during the first two days following surgery, and no difference was found between the groups on the third day. No significant discrepancies at any time were found between groups in terms of blood loss, length of hospitalization, knee range of motion, and KOOS score. Complications requiring further treatment were observed in one patient from the study group and ten patients from the control group. Conclusion: The use of suction drains after TKA with TXA did not alter early postoperative outcomes. [ABSTRACT FROM AUTHOR]

Bronchiolitis is an acute respiratory illness that is the leading cause of hospitalization in young children. This document aims to update the consensus document published in 2014 to provide guidance on the current best practices for managing bronchiolitis in infants. The document addresses care in both hospitals and primary care. The diagnosis of bronchiolitis is based on the clinical history and physical examination. The mainstays of management are largely supportive, consisting of fluid management and respiratory support. Evidence suggests no benefit with the use of salbutamol, glucocorticosteroids and antibiotics with potential risk of harm. Because of the lack of effective treatment, the reduction of morbidity must rely on preventive measures. De-implementation of non-evidence-based interventions is a major goal, and educational interventions for clinicians should be carried out to promote high-value care of infants with bronchiolitis. Well-prepared implementation strategies to standardize care and improve the quality of care are needed to promote adherence to guidelines and discourage non-evidence-based attitudes. In parallel, parents' education will help reduce patient pressure and contribute to inappropriate prescriptions. Infants with pre-existing risk factors (i.e., prematurity, bronchopulmonary dysplasia, congenital heart diseases, immunodeficiency, neuromuscular diseases, cystic fibrosis, Down syndrome) present a significant risk of severe bronchiolitis and should be carefully assessed. This revised document, based on international and national scientific evidence, reinforces the current recommendations and integrates the recent advances for optimal care and prevention of acute bronchiolitis.

Pediatric patients frequently present to emergency departments with complaint of foreign bodies in the ear and/or nose. Emergency nurse practitioners need the knowledge base to safely and effectively manage ear and nose foreign bodies in urgent and emergent care settings. The purpose of this article is to teach the common anatomical sites where foreign bodies are placed, the make-up of foreign body material, procedural technique of removal, and specific circumstances that require specialty referral.

This study aims at understanding the rationale behind performing prefeed gastric aspirations in preterm infants, how nurses and physicians interpret the gastric aspiration and variations between them, and illuminating potential barriers for omitting routine prefeed aspiration. Nurses and physicians from all Danish neonatal intensive care units completed a questionnaire. Of 682 participants, the majority (94%) indicated that they routinely performed prefeed aspiration, primarily to check the feeding tube placement (nurses: 88%, physicians: 46%). Nurses feared necrotizing enterocolitis when observing a large gastric residual (GR) volume (31%) and green-stained GR (63%). Fewer nurses relative to physicians had "no worries" related to large volumes (15% vs 34%) or green-stained GR (14% vs 24%, both P <.01). More nurses than physicians intended to pause enteral feeding when observing green-stained GR (31% vs 16%, P <.01) and more nurses were concerned of completely omitting routine gastric aspirations (90% vs 46%, P <.05). The rationale behind the clinical use of GR volume and color as markers of necrotizing enterocolitis and feeding intolerance differs markedly between nurses and physicians in Denmark. If routine prefeed gastric aspiration should be omitted, special focus on information about early signs of necrotizing enterocolitis and methods to check tube placement is needed.

Background: During COVID-19 pandemic, most studies have focused on sampling technique in adults. Considering the need to be aware of the effectiveness and evaluation of sampling methods in children, we have motivated a search for introducing and performing sampling techniques, especially upper respiratory tract sampling in children. We systematically reviewed the literature to understand the performance of different sampling methods in children in COVID-19. Methods: We systematically reviewed PubMed, Google Scholar, medRxiv, and bioRxiv (last retrieval August 1st, 2021) for comparative studies of deferent sampling techniques by using the search keywords including: children, pediatric sampling, nasopharyngeal, COVID-19, oropharyngeal, swabs, SARS, CoV2. 8 relevant manuscripts were sourced from a total of 4852 search results. Results: Nasopharyngeal (NP) swabs testing significantly had higher positivity rate over oropharyngeal swab in detecting SARS-CoV-2. Nasal swab has a low sensitivity in detecting SARSCoV-2 in children when referred to the Nasopharyngeal Aspiration (NPA), whereas its specificity is high. Therefore, NPA can be as the gold standard for detection of SARS-CoV-2. Conclusion: Saliva is not a useful for diagnosing COVID-19 in children. Negative nasopharyngeal and oropharyngeal swabs do not rule out COVID-19 and in patients with strong clinical suspicion, and Bronchoalveolar lavage (BAL) can be helpful. [ABSTRACT FROM AUTHOR]

Background: Recently, the International Liaison Committee on Resuscitation published a systematic review that concluded that routine suctioning of clear amniotic fluid in the delivery room might be associated with lower oxygen saturation (SpO2) and 10 min Apgar score. The aim of this study was to examine the effect of delivery room airway suctioning on the clinical appearance, including muscle tone and skin colour, of video-recorded term and preterm infants born through mainly clear amniotic fluid. Methods: This was a single-centre observational study using transcribed video recordings of neonatal stabilizations. All infants who received delivery room positive pressure ventilation (PPV) from August 2014 to November 2016 were included. The primary outcome was the effect of airway suctioning on muscle tone and skin colour (rated 0–2 according to the Apgar score), while the secondary outcome was the fraction of infants for whom airway suction preceded the initiation of PPV as a surrogate for "routine" airway suctioning. Results: Airway suctioning was performed in 159 out of 302 video recordings and stimulated a vigorous cry in 47 (29.6%) infants, resulting in improvements in muscle tone (p = 0.09) and skin colour (p < 0.001). In 43 (27.0%) infants, airway suctioning preceded the initiation of PPV. Conclusions: In this single-centre observational study, airway suctioning stimulated a vigorous cry with resulting improvements in muscle tone and skin colour. Airway suctioning was often performed prior to the initiation of PPV, indicating a practice of routine suctioning and guideline non-compliance. [ABSTRACT FROM AUTHOR]

Complex persistent air leak (PAL) is a clinical condition which is difficult to treat. Herein, we report the clinical case of an 18‐year‐old woman with lung and bone metastases due an ultrarare sarcoma: "round cell sarcoma non‐Ewing". She developed persistent air leaks due to an alveolopleural fistula which developed following two cycles of chemotherapy with doxorubicin. Chest drainage with suction failed to resolve the air leaks, while surgical treatment was unfeasible due to the poor clinical condition of the patient. Thus, she was reviewed for endoscopic treatment with one‐way endobronchial valves. A small valve was sequentially inserted within each segment of the right upper bronchus to occlude the entire upper lobe. Two days after the procedure, resolution of the air leaks were obtained. Chest drainage was removed 5 days later and the patient was discharged. Chemotherapy was resumed. The patient died 7 months later because of disease progression. [ABSTRACT FROM AUTHOR]

Background: Saliva possesses antiviral activity, with submandibular-sublingual (SMSL) saliva having higher antiviral activity than parotid saliva. Various salivary proteins have inactivating effects on influenza A virus (IAV), but the detailed relationship between antiviral proteins and salivary anti-IAV activities in the parotid and SMSL glands is unknown. Here, to identify salivary proteins with anti-IAV activity, salivary proteins from parotid and SMSL glands were identified, quantified, and compared using liquid chromatography-mass spectrometry. Methods: Twelve healthy male volunteers participated in the study. Parotid and SMSL saliva was collected by suction and collection devices. We assessed anti-IAV activities, protein concentrations, and protein-bound sialic acid concentrations in parotid and SMSL saliva. Results: SMSL had significantly higher anti-IAV activity than parotid saliva. SMSL also had higher concentrations of glycoproteins, such as mucin 5B and mucin 7, protein-bound sialic acid, cystatins, and lysozyme C, compared with parotid saliva. Salivary mucin 5B and mucin 7 concentrations significantly positively correlated with the salivary protein-bound sialic acid concentration. Salivary anti-IAV activity significantly positively correlated with protein-bound sialic acid, mucin 5B, mucin 7, cystatin-C, -S, and -SN concentrations. Conclusion: Salivary mucins, cystatins, and lysozyme C contribute to the high anti-IAV activity of SMSL saliva. [ABSTRACT FROM AUTHOR]
