Abstract
New Omicron subvariants continue to emerge throughout the world. In particular, the XBB subvariant, which is a recombinant virus between BA.2.10.1.1 and BA.2.75.3.1.1.1, as well as the BA.2.3.20 and BR.2 subvariants that contain mutations distinct from BA.2 and BA.2.75, are currently increasing in proportion of variants sequenced. Here we show that antibodies induced by 3-dose mRNA booster vaccination as well as BA.1- and BA.4/5-wave infection effectively neutralize BA.2, BR.2, and BA.2.3.20 but have significantly reduced efficiency against XBB. In addition, the BA.2.3.20 subvariant exhibits enhanced infectivity in the lung-derived CaLu-3 cells and in 293T-ACE2 cells. Overall, our results demonstrate that the XBB subvariant is highly neutralization resistant, which highlights the need for continued monitoring of the immune escape and tissue tropism of emerging Omicron subvariants.

Abstract
Newly emerging Omicron subvariants continue to emerge around the world, presenting potential challenges to current vaccination strategies. This study investigates the extent of neutralizing antibody escape by new subvariants XBB.1.5, CH.1.1, and CA.3.1, as well as their impacts on spike protein biology. Our results demonstrated a nearly complete escape of these variants from neutralizing antibodies stimulated by three doses of mRNA vaccine, but neutralization was rescued by a bivalent booster. However, CH.1.1 and CA.3.1 variants were highly resistant to both monovalent and bivalent mRNA vaccinations. We also assessed neutralization by sera from individuals infected during the BA.4/5 wave of infection and observed similar trends of immune escape. In these cohorts, XBB.1.5 did not exhibit enhanced neutralization resistance over the recently dominant BQ.1.1 variant. Notably, the spike proteins of XBB.1.5, CH.1.1, and CA.3.1 all exhibited increased fusogenicity compared to BA.2, correlating with enhanced S processing. Overall, our results support the administration of new bivalent mRNA vaccines, especially in fighting against newly emerged Omicron subvariants, as well as the need for continued surveillance of Omicron subvariants.

Abstract
The continued evolution of SARS-CoV-2 has led to the emergence of several new Omicron subvariants, including BQ.1, BQ.1.1, BA.4.6, BF.7, and BA.2.75.2. Here, we examine the neutralization resistance of these subvariants against sera from 3-dose vaccinated healthcare workers, hospitalized BA.1-wave patients, and BA.4/5-wave patients. We found enhanced neutralization resistance in all new subvariants, especially in the BQ.1 and BQ.1.1 subvariants driven by N460K and K444T mutations, as well as the BA.2.75.2 subvariant driven largely by its F486S mutation. All Omicron subvariants maintained their weakened infectivity in Calu-3 cells, with the F486S mutation driving further diminished titer for the BA.2.75.2 subvariant. Molecular modeling revealed the mechanisms of antibody-mediated immune evasion by R346T, K444T, F486S, and D1199N mutations. Altogether, these findings shed light on the evolution of newly emerging SARS-CoV-2 Omicron subvariants.

Abstract
INTRODUCTION Emergency medicine (EM) programs train residents to perform clinical procedures with known iatrogenic risks. Currently, there is no established framework for graduating medical students to demonstrate procedural competency prior to matriculating into residency. Mastery-based learning has demonstrated improved patient-safety outcomes. Incorporation of this framework allows learners to demonstrate procedural competency to a predetermined standard in the simulation laboratory prior to performing invasive procedures on patients in the clinical setting. This study describes the creation and implementation of a competency-based procedural curriculum for first-year EM residents using simulation to prepare learners for supervised participation in procedures during patient care. METHODS Checklists were developed internally for five high-risk procedures (central venous line placement, endotracheal intubation, lumbar puncture, paracentesis, chest tube placement). Performance standards were developed using Mastery-Angoff methods. Minimum passing scores were determined for each procedure. Over a two-year period, 38 residents underwent baseline assessment, deliberate practice, and post-testing against the passing standard score to demonstrate procedural competency in the simulation laboratory during intern orientation. RESULTS We found that 37% of residents required more than one attempt to achieve the minimum passing score on some procedures, however, all residents ultimately met the competency standard on all five high-risk procedures in simulation. One critical incident of central venous catheter guideline retention was identified in the simulation laboratory during the second year of implementation. CONCLUSION All incoming first-year EM residents demonstrated procedural competence on five different procedures using a mastery-based educational framework. A competency-based EM curriculum allowed for demonstration of procedural competence prior to resident participation in supervised clinical patient care.

Abstract
Continued evolution of SARS-CoV-2 has led to the emergence of several new Omicron subvariants, including BQ.1, BQ. 1.1, BA.4.6, BF.7 and BA.2.75.2. Here we examine the neutralization resistance of these subvariants, as well as their ancestral BA.4/5, BA.2.75 and D614G variants, against sera from 3-dose vaccinated health care workers, hospitalized BA.1-wave patients, and BA.5-wave patients. We found enhanced neutralization resistance in all new subvariants, especially the BQ.1 and BQ.1.1 subvariants driven by a key N460K mutation, and to a lesser extent, R346T and K444T mutations, as well as the BA.2.75.2 subvariant driven largely by its F486S mutation. The BQ.1 and BQ.1.1 subvariants also exhibited enhanced fusogenicity and S processing dictated by the N460K mutation. Interestingly, the BA.2.75.2 subvariant saw an enhancement by the F486S mutation and a reduction by the D1199N mutation to its fusogenicity and S processing, resulting in minimal overall change. Molecular modelling revealed the mechanisms of receptor-binding and non-receptor binding monoclonal antibody-mediated immune evasion by R346T, K444T, F486S and D1199N mutations. Altogether, these findings shed light on the concerning evolution of newly emerging SARS-CoV-2 Omicron subvariants.

Abstract
The burgeoning occupational callings literature has shown that feeling called to a job is associated with an array of positive job-, career-, and health-related outcomes. However, recent studies have begun to indicate that there may also be a "negative side" of callings. The present study builds on this emerging perspective to examine whether feeling called to a job makes helping professionals more vulnerable to the negative effects of acute stressors. Specifically, we integrated identity, cognitive rumination, and psychological detachment theories to explain how feeling called to one's job (i.e., the strength of one's calling intensity) might bolster the negative, indirect relationship between emotionally disturbing work and strain (i.e., mental exhaustion, sleep quality, and alcohol consumption) through negative work rumination. Results from a 10-week diary study with a national U.S. sample of 211 paramedics revealed that on weeks that paramedics experienced more emotionally disturbing work, they engaged in greater levels of negative work rumination, which in turn was associated with greater mental exhaustion and worse sleep quality, but not greater alcohol consumption. In addition, calling intensity moderated the indirect effect of emotionally disturbing work on both mental exhaustion and sleep quality, such that these indirect effects were stronger among those with higher (vs. lower) levels of calling intensity. These results provide evidence that employees who feel most called to their jobs may be particularly vulnerable to short-term negative outcomes associated with emotionally disturbing work.

Abstract
BACKGROUND We sought to describe ventilation rates during out-of-hospital cardiac arrest (OHCA) resuscitation and their associations with airway management strategy and outcomes. METHODS We analyzed continuous end-tidal carbon dioxide capnography data from adult OHCA enrolled in the Pragmatic Airway Resuscitation Trial (PART). Using automated signal processing techniques, we determined continuous ventilation rate for consecutive 10-second epochs after airway insertion. We defined hypoventilation as a ventilation rate <6 breaths/min. We defined hyperventilation as a ventilation rate >12 breaths/min. We compared differences in total and percentage post-airway hyper- and hypoventilation between airway interventions (laryngeal tube (LT) vs. endotracheal intubation (ETI). We also determined associations between hypo-/hyperventilation and OHCA outcomes (ROSC, 72-hour survival, hospital survival, hospital survival with favorable neurologic status). RESULTS Adequate post-airway capnography were available for 1,010 (LT n=714, ETI n=296) of 3,004 patients. Median ventilation rates were: LT 8.0 (IQR 6.5-9.6) breaths/min, ETI 7.9 (6.5-9.7) breaths/min. Total duration and percentage of post-airway time with hypoventilation were similar between LT and ETI: median 1.8 vs. 1.7 minutes, p=0.94; median 10.5% vs. 11.5%, p=0.60. Total duration and percentage of post-airway time with hyperventilation were similar between LT and ETI: median 0.4 vs. 0.4 minutes, p=0.91; median 2.1% vs. 1.9%, p=0.99. Hypo- and hyperventilation exhibited limited associations with OHCA outcomes. CONCLUSION In the PART Trial, EMS personnel delivered post-airway ventilations at rates satisfying international guidelines, with only limited hypo- or hyperventilation. Hypo- and hyperventilation durations did not differ between airway management strategy and exhibited uncertain associations with OCHA outcomes.

Abstract
Bystander cardiopulmonary resuscitation (CPR) is critical to increasing survival from out-of-hospital cardiac arrest. However, the percentage of cases in which an individual receives bystander CPR is actually low, at only 35% to 40% globally. Preparing lay responders to recognize the signs of sudden cardiac arrest, call 9-1-1, and perform CPR in public and private locations is crucial to increasing survival from this public health problem. The objective of this scientific statement is to summarize the most recent published evidence about the lay responder experience of training, responding, and dealing with the residual impact of witnessing an out-of-hospital cardiac arrest. The scientific statement focuses on the experience-based literature of actual responders, which includes barriers to responding, experiences of doing CPR, use of an automated external defibrillator, the impact of dispatcher-assisted CPR, and the potential for postevent psychological sequelae. The large body of qualitative and observational studies identifies several gaps in crucial knowledge that, if targeted, could increase the likelihood that those who are trained in CPR will act. We suggest using the experience of actual responders to inform more contextualized training, including the implications of performing CPR on a family member, dispelling myths about harm, training and litigation, and recognition of the potential for psychologic sequelae after the event.

Abstract
Background The timed up-and-go test (TUGT) is a quick, reliable, and valid assessment tool for evaluating functional mobility or dynamic balance. Aims The purpose of this study was to establish the normative values for TUGT in children aged 4 to 11 years old in Surat, India. Methods A total of 420 children (210 boys and 210 girls) were included. Subjects were divided into seven age groups. In each age group, 60 (30 males and 30 females) subjects were included. Subjects were randomly recruited from primary schools and underwent three trials of the TUGT. Then, the mean of the three TUGT trials was calculated for each participant. Results We formulated normative reference values for each of the seven age groups. The mean and standard deviation of the TUGT score across the total population was 6.00 ± 1.15 seconds. TUGT scores were compared between age groups and genders. Between boys and girls, we found no significant differences. Among the age groups, however, we found significant differences, with a P value of less than 0.001. Thus, only age showed a moderate negative correlation with TUGT score. Conclusions This study provides normative reference values for the TUGT among Indian children aged four to 11 years old. We found that no differences existed between the TUGT results according to genders. Conversely, age had a moderate negative correlation: a comparison of TUGT scores among the ages revealed significant differences between the age groups.

Abstract
Introduction:
Rural prehospital care settings are underrepresented in the out-of-hospital cardiac arrest (OHCA) literature. We analyzed a nationwide database of emergency medical services (EMS) incidents in the US to describe treatment patterns and the odds of return of spontaneous circulation (ROSC) among rural OHCA patients.
Methods:
Using the 2018 National EMS Informational System dataset, we analyzed OHCA incidents where CPR provided by EMS was documented. We excluded incidents in which trauma was involved, patient age <18 years, transport was not by completed by an advanced life support unit, or response time >60 minutes. The primary outcome was ROSC during the EMS incident. Multivariable logistic regression was performed comparing rural, suburban, and urban settings while controlling for age and gender, incident location type, response time, CPR prior to EMS arrival, arrest witnessed by EMS, initial rhythm, epinephrine administration, mechanical CPR, and advanced airway used.
Results:
A total of 60,281 OHCA incidents were identified for inclusion, including 5,013 (8.6%) in rural settings. Rural OHCA patients achieved ROSC in 28.8% of cases, compared to 33.0% in urban or suburban settings (p<0.001). Neither age nor gender significantly differed between settings (Table 1). Rural OHCA incidents had greater response times (7.5 vs. 5.9 minutes, p<0.001) and were less likely to receive epinephrine (71.6% vs. 74.9%, p<0.001). Further, EMS were more likely to use mechanical CPR (29.8% vs. 28.1%, p=0.01) and less likely to provide an advanced airway (56.3% vs. 50.5%, p<0.001) for rural OHCA. On multivariable logistic regression, rural OHCA patients had lower odds of achieving ROSC than urban OHCA patients after controlling for other factors (0.80, 95%CI: 0.75-0.86).
Conclusion:
In this national sample of EMS-treated OHCA, rural patients were less likely to achieve ROSC than patients in urban or suburban settings.

Abstract
INTRODUCTION One of the barriers to improving cardiac arrest survival is the low rate of cardiopulmonary resuscitation (CPR) provision. Identifying this as a public health issue, many medical students often assist in training the community in CPR. However, these experiences are often short and are not associated with structured resuscitation education, limiting the student's and the community's learning. In this assessment, we identified a need and developed a curriculum, including defined goals and objectives, for an undergraduate medical education (UME) elective in CPR. METHODS At an academic university environment with a strong UME program, we developed a longitudinal UME elective in CPR. The curriculum is a four-year longitudinal experience, which satisfies two weeks of their fourth year of medical school. The curriculum includes structured training over the four-year period in the fundamentals of resuscitation science (through didactics, journal club, and hands-on skills training), in addition to structured community CPR teaching. The elective concludes with a final hands-on summative appraisal. Data concerning medical student program enrollment, CPR training events conducted, venues of events, and the number of individuals trained were collected over a five-year period. RESULTS The CPR elective was developed with clear goals and objectives based on identified needs. Over the five-year period, 186 medical students completed the CPR longitudinal elective, accounting for 8.4% of the total medical student population. Students completed curriculum requirements and satisfied both didactic and hands-on training with all students passing the final summative appraisal. Over the five-year period, students trained 8,694 people in bystander CPR. The summative evaluation had a 100% pass rate. CONCLUSION Implementation of a longitudinal CPR elective improved resuscitation science education for medical students and fostered increased community CPR training. This describes one local effort to improve resuscitation science education and training for medical students. Further work will need to be done to evaluate the impact of UME resuscitation curricula on medical student career choice and resuscitation outcomes.

Abstract
Accumulating data advocates that inflammatory mediators may contribute to depression in experimental models as well as in humans. Nonetheless, whether anti-inflammatory treatments can prevent depression still remains controversial. To substantiate our hypothesis, we used an interferon-α-2b model of depression using Sprague Dawley rats. Interferon-α-2b is a cytokine which activates immune response and also produces depression. The animals were treated for 21 days with aspirin (10 mg/kg, per oral (p.o.)) dexamethasone (1 mg/kg p.o.) and amitriptyline (10 mg/kg p.o.). Amitriptyline was used as reference standard, and given concurrently with aspirin and dexamethasone to examine any synergy. Interferon-α-2b (6000 IU/kg, intraperitoneal (i.p.)) was administered in all the above groups daily, except normal control. Tests performed included sucrose preference test, behavioural tests like forced swim test, elevated plus maze, light dark box and locomotor activity along with biochemical estimations like serum cortisol and brain neurotransmitters. The rats in the group treated with Interferon-α-2b produced depressive behaviour in rats. We found that animals treated with aspirin decreased immobility time in forced swim test, increased sucrose preference, decreased serum cortisol and increased brain serotonin levels signifying antidepressant action. In contrast, there was no effect in groups treated with dexamethasone. Our results suggest that aspirin can serve as a potential antidepressant both individually and as adjuvant agent in the treatment of depression. Inhibition of the cyclo-oxygenase-2 levels and prostaglandins concentration or any other potential physiological and biochemical mechanisms may be involved in antidepressant effect.

Abstract
Carbamazepine is widely preferred therapy for the treatment of epilepsy. However, oral therapy results in slower brain uptake and systemic side effects. Intranasal route can achieve faster brain uptake, but poor aqueous solubility of carbamazepine is the main obstacle for administration by nasal route. The purpose of this study was to prepare and evaluate intranasal oil in water microemulsion of carbamazepine to improve its solubility and enhance the brain uptake. Intranasal microemulsion of carbamazepine was prepared by water titration method using oleic acid as oil, Tween 80 as surfactant and Transcutol® as cosurfactant. Microemulsions were evaluated for various physical parameters including globule size, viscosity, pH and conductivity. Toxicity study of microemulsion was carried out by employing sheep nasal mucosa. The microemulsion was also evaluated by maximal electric shock, and the brain uptake study was done using HPLC method. The microemulsion was stable and transparent with average globule size of 21.03 nm and did not show any toxic symptoms. It showed reduction in the hind limb extension phase and faster recovery from seizures in comparison to oral microemulsion and nasal solution. Higher brain/plasma ratio was obtained with nasal microemulsion in comparison to ratio obtained after intraperitoneal injection of carbamazepine solution.

Abstract
AIM Outcomes from out-of-hospital cardiac arrest (OHCA) may improve if rescuers perform chest compressions (CCs) deeper than the previous recommendation of 38-51mm and consistent with the 2010 AHA Guideline recommendation of at least 51mm. The aim of this study was to assess the relationship between CC depth and OHCA survival. METHODS Prospective analysis of CC depth and outcomes in consecutive adult OHCA of presumed cardiac etiology from two EMS agencies participating in comprehensive CPR quality improvement initiatives. ANALYSIS Multivariable logistic regression to calculate adjusted odds ratios (aORs) for survival to hospital discharge and favorable functional outcome. RESULTS Among 593 OHCAs, 136 patients (22.9%) achieved return of spontaneous circulation, 63 patients (10.6%) survived and 50 had favorable functional outcome (8.4%). Mean CC depth was 49.8±11.0mm and mean CC rate was 113.9±18.1CCmin(-1). Mean depth was significantly deeper in survivors (53.6mm, 95% CI: 50.5-56.7) than non-survivors (48.8mm, 95% CI: 47.6-50.0). Each 5mm increase in mean CC depth significantly increased the odds of survival and survival with favorable functional outcome: aORs were 1.29 (95% CI 1.00-1.65) and 1.30 (95% CI 1.00-1.70) respectively. CONCLUSION Deeper chest compressions were associated with improved survival and functional outcome following OHCA. Our results suggest that adhering to the 2010 AHA Guideline-recommended depth of at least 51mm could improve outcomes for victims of OHCA.

Abstract
Although electron microscopy no longer enjoys the important role in the diagnosis of interstitial lung diseases that it had in the 1960s and 1970s, it remains an important adjunct in the differential diagnosis of certain pulmonary diseases. Examples include various manifestations of systemic lupus erythematous pneumonitis, in which the presence of tubuloreticular structures and electron-dense deposits are useful for diagnosis; immotile cilia disorders, in which qualitative and now quantitative studies of the cilia of respiratory epithelial cells can help to establish the diagnosis; infections by viruses and other subcellular microorganisms as shown by the role played by electron microscopy in the initial diagnosis of the Hantavirus pulmonary syndrome; pneumoconioses, in which, in conjunction with elemental analysis probes, scanning electron microscopy is of critical importance in establishing the presence of offending foreign compounds in lung tissue or fluids; pulmonary fibrilloses, such as amyloidosis, light chain disease, and fibrillary glomerulonephritis, affecting the lung; and cases of alveolar proteinosis or Langerhans cell granulomatosis diagnosed from fluids such as bronchoalveolar lavages or small tissue samples. As important, electron microscopy remains of enormous usefulness in the study of early structural events leading to the pathogenesis of diseases. For example, recent uses of the technique have focused on the alveolar-capillary wall damage induced by alveolitis in hypersensitivity pneumonitis and sarcoidosis. In summary, electron microscopy remains a useful method in the study and diagnosis of some interstitial lung diseases, but because of its expense it is incumbent on the clinician to use good judgment in the selection of cases and diseases for study by this method.

Abstract
BACKGROUND & AIMS Little is known of the physiological mechanisms that control cellular renewal in the pancreatic excretory duct system. This study investigated the effects of potential regulatory substances on the growth of cultured guinea pig pancreatic duct epithelial monolayers. METHODS Pancreatic duct explants were cultured for 3 days on plastic and on permeable filters in the presence and absence of different substances. Growth of epithelial monolayers from these explants was measured by 5-bromo-2'-deoxyuridine incorporation and morphometric procedures. RESULTS Epidermal growth factor and insulin both enhanced monolayer growth and together had an additive effect. Transforming growth factor alpha enhanced and transforming growth factor beta inhibited growth, whereas glucagon, somatostatin, pancreatic polypeptide, secretin, cerulein, bombesin, and dexamethasone had no significant effects. Monolayer growth on type 1 collagen-coated filters was enhanced when compared with that of monolayers grown on tissue culture plastic. Cell growth from explants on filters coated with type IV collagen and fibronectin was comparable with that on plastic, whereas growth on Matrigel- or laminin-coated filters was reduced. CONCLUSIONS Insulin, transforming growth factors, and substrate components modulate growth of pancreatic duct epithelial cells in vitro, suggesting that they are important regulators of cell division in the excretory duct system of the intact pancreas.

Abstract
Surfactant protein-B (SP-B) is a small hydrophobic polypeptide that enhances spreading and stability of surfactant phospholipids in the alveolus of the lung. Decreased expression of SP-B is associated with respiratory failure in premature infants and in adult patients with acute respiratory distress syndrome (ARDS). Tumor necrosis factor-alpha (TNF-alpha) and 12-O-tetradecanoylphorbol-13 acetate (TPA) cause ARDS-like lung injury in vivo. Inhibitory effects of TPA and TNF-alpha on SP-B mRNA expression in vitro were mediated by decreased SP-B mRNA stability rather than by decreased rate of SP-B gene transcription. In the present study, a human pulmonary adenocarcinoma cell line, NCI H441-4, was stably transfected with expression vectors consisting of the thymidine kinase (TK) promotor and human growth hormone (hGH) gene, in which the hGH 3'-untranslated region (3'-UTR) was replaced by the 2.0-kb human SP-B cDNA [pTKGH(SP-B2.0)] or the 837-bp human SP-B 3'-UTR [pTKGH(SP-B.837)]. The mRNAs and cellular growth hormone protein generated from the chimeric TKGH(SP-B2.0) and TKGH(SP-B.837) genes were each inhibited by approximately 50% by TPA and TNF-alpha. Dexamethasone decreased the inhibitory effects of TPA and TNF-alpha. The inhibition of steady-state hGH-SP-B mRNA by TPA and TNF-alpha was mediated by a cis-active element located in the 3-UTR region of SP-B mRNA.
