Abstract
Despite the existing research and evidence for teacher praise, this strategy has been studied less frequently in secondary school settings. To better understand and support teacher praise across all school settings, it is important to understand gaps in the literature, especially related to middle and high school settings. In this review, we examined middle and high school praise research by screening a total of 523 unique abstracts and identified, reviewed, and coded 32 empirical studies. A study was included if (a) praise was the focus (i.e., identified as either an independent or dependent variable), (b) the study was empirical and peer-reviewed, (c) at least 51% of the sample included middle or high school students, (d) praise involved teachers praising students (rather than student-to-student praise), and (e) the study took place in a school/classroom setting. Descriptive methods were used to identify and code praise themes. We found most studies (71%) examined the effects of teacher praise on student behavior or the effects of teacher training on teachers' use of praise. Few studies examined praise preferences at the secondary level. We also summarized the methodological characteristics and findings from 32 studies and provide recommendations for future research and practice.

Abstract
INTRODUCTION Flexible nasendoscopy (FNE) is the principal assessment method for vocal cord movement. Because the procedure is inherently subjective it may not be possible for clinicians to grade the degree of vocal cord movement reliably. The aim of this study was to assess the accuracy and consistency of grading vocal cord movement as viewed via FNE. METHODS Thirty FNE videos, without sound or clinical information, were assessed by six consultant head and neck surgeons. The surgeons were asked to assess and grade right and left vocal cord movement independently, based on a five-category scale. This process was repeated three times on separate occasions. Agreement and reliability were assessed. RESULTS Mean overall observed inter-rater agreement was 67.7% (sd 1.9) with the five-category scale, increasing to 91.4% (sd 1.9) when a three-category scale was derived. Mean overall observed intra-rater agreement was 78.3% (sd 9.7) for five categories, increasing to 93.1% (sd 3.3) for three categories. Discriminating vocal cord motion was less reliable using the five-category scale (k = 0.52) than with the three-category scale (k = 0.68). CONCLUSIONS This study demonstrates quantitatively that it is challenging to accurately and consistently grade subtle differences in vocal cord movement, as proven by the reduced agreement and reliability when using a five-point scale instead of a three-point scale. The study highlights the need for an objective measure to help in the assessment of vocal cord movement.

Abstract
INTRODUCTION The 31-day target in urgent suspicion of cancer (USOC) referrals fast-tracks patients through the cancer pathway. Local anaesthetic (LA) biopsy can be performed during an outpatient clinic and may improve pathway times. The aim of this study was to compare LA biopsy in head and neck USOC referrals with the traditional general anaesthetic (GA) pathway. METHODS This was a retrospective cohort study of USOC referrals to the NHS Greater Glasgow and Clyde head and neck multidisciplinary team between 1 June 2018 and 28 December 2020, and compared pathway times in LA and GA biopsies. RESULTS The mean number of days from clinic to biopsy was 4.4 in the LA group and 28.0 in the GA group. This was significantly faster in the LA biopsy group (p < 0.05). The overall pathway time in the LA and GA biopsy groups was 35.7 and 61.5 days, respectively, and was significantly faster in LA biopsy group (p < 0.05). CONCLUSIONS The LA cohort had significantly faster pathway times compared with GA biopsy. LA biopsy requires careful patient selection, but is an effective alternative to GA biopsy in the appropriate patient group.

Abstract
INTRODUCTION The majority of head and neck cancer referrals are received through primary care. A proportion of cancer referrals are received through secondary care specialties. Local delivery plan (LDP) targets in Scotland for cancer investigation are set at 31 days for diagnosis and 62 days to start treatment. The aim was to audit referrals made through non-primary care pathways compared with the standard primary care pathways against LDP targets. METHODS New head and neck cancer patients between 1 January 2014 and 1 January 2019 were included. Pathway points were recorded between referral to outpatient clinic, time to multidisciplinary team discussion (MDT) and finally MDT to treatment. RESULTS 1,276 new patient referrals were received over a 5-year period. Of these, 136 (10%) were referred via non-primary care pathways. The mean time for urgent suspicion of cancer (USoC) referrals to start treatment was 77 days (15 days over target) and for outpatient secondary care referrals was 102 days (40 days over target) (p<0.05). When treatment intent was considered, 841/1,131 (75%) of patients referred via primary care were treated curatively compared with 49/99 (49%) (p<0.05) of patients referred through the secondary outpatient pathway. CONCLUSION Patients with head and neck cancer referred from other outpatient specialties face delays commencing cancer treatment and are also associated with a greater likelihood of being treated with palliative intent.

Abstract
Abstract
Introduction
Many factors influence age of presentation with and survival following ST-segment myocardial infarction (STEMI). These include age, mode of, and time-delay to emergency treatment, diabetes and smoking. We sought to assess whether overall social deprivation status is associated with age of presentation and mortality following STEMI patients treated with primary PCI.
Methods
All patients treated emergently for STEMI in a large Northern Irish tertiary hospital from 2013 – 2017 were reviewed. Social deprivation is determined as a composite score relating to income, crime etc, and assigned to small geographical regions by the Northern Ireland Statistics and Research Agency. Deprivation score was assigned to patients based on their postcode. The database was ranked by social deprivation score and divided in to quintiles. The most (Grp 1) and least (Grp 5) deprived quintiles were compared. Mortality was determined from a national electronic health record.
Results
1,192 patients were included in the analysis. Mean follow up was 52.5 months (SD 15.6), minimum follow up was 35.6 months. There was no difference in gender: 70.1% male in Grp 1 vs 75.2% male in Grp 5 (p=0.68); no difference in ECG to balloon time: mean 89.9mins (95% CI 84.9–94.9) Grp 1 vs 90.5mins (95% CI 86.2–94.9) Grp 5 (p=0.86). The more deprived group was younger: mean age 60.6 (95% CI 59.5–61.6) vs 65.2 (95% CI 64.2–66.3) (p<0.000). Crude survival measured by Log-rank test was the same between the groups (p=0.52). Following Cox-regression adjustment for age, survival was longer in the least deprived group (p=0.042).
Conclusion
Social deprivation is associated with both a younger age of presentation with, and a higher mortality following STEMI. This is important variable is often overlooked in medical literature and should be further studied.

Abstract
This national professional society guidance lays out operational and ethical principles for decision-making during a pandemic, in the immediate context of COVID-19 in the early 2020 surge iteration but with potential ongoing relevance. It identifies the different phases of a pandemic and the implications for capacity and mutual aid within a national healthcare system, and introduces a revised CRITCON-PANDEMIC framework for shared operational responsibilities and clinical decision-making. Usual legal and ethical frameworks should continue to apply while capacity and mutual aid are available (CRITCON-PANDEMIC levels 0-3); clinicians should focus on current clinical needs and should not treat patients differently because of anticipated future pressures. In conditions of resource limitation (CRITCON-PANDEMIC 4), a structured and equitable approach is necessary and an objective Decision Support Aid is proposed. In producing this guidance, we emphasise that all patients must be treated with respect and without discrimination, because everyone is of equal value. The guidance has been put together with input from patient and public groups and aims to provide standards that are fair to everyone. We acknowledge that COVID-19 is a new disease with a partial and evolving knowledge base, and aim to provide an objective clinical decision-making framework based on the best available information. It is recognised that a factual assessment of likely benefit may take into account age, frailty and comorbidities, but the guidance emphasises that every assessment must be individualised on a balanced, case by case, basis and may inform clinical judgement but not replace it. The effects of a comorbidity on someone's ability to benefit from critical care should be individually assessed. Measures of frailty should be used with care, and should not disadvantage those with stable disability.

Abstract
In this study, we used bi-temporal airborne lidar data to compare changes in vegetation height proximal to anthropogenic disturbances in the Oil Sands Region of Alberta, Canada. We hypothesize that relatively low-impact disturbances such as seismic lines will increase the fragmentation of wetlands, resulting in shrub growth. Bi-temporal lidar data collected circa 2008 and 2018 were used to identify correspondence between the density of anthropogenic disturbances, wetland shape complexity and changes in vegetation height within >1800 wetlands near Fort McKay, Alberta, Canada. We found that up to 50% of wetlands were disturbed by anthropogenic disturbance in some parts of the region, with the highest proportional disturbance occurring within fens. Areas of dense anthropogenic disturbance in bogs resulted in increased growth and expansion of shrubs, while we found the opposite to occur in fens and swamps during the 10-year period. Up to 30% of bogs had increased shrubification, while shrub changes in fens and swamps varied depending on density of disturbance and did not necessarily correspond with shrub growth. As wetland shapes became increasingly elongated, the prevalence of shrubs declined between the two time periods, which may be associated with hydrological drivers (e.g. elongated may indicate surface and ground-water discharge influences). The results of this study indicate that linear disturbances such as seismic lines, considered to have relatively minimal impacts on ecosystems, can impact proximal wetland shape, fragmentation and vegetation community changes, especially in bogs.

Abstract
Phase II clinical trials have reported that acute treatment of surgical skin wounds with the therapeutic peptide alpha Connexin Carboxy-Terminus 1 (αCT1) improves cutaneous scar appearance by 47% 9-month postsurgery. While Cx43 and ZO-1 have been identified as molecular targets of αCT1, the mode-of-action of the peptide in scar mitigation at cellular and tissue levels remains to be further characterized. Scar histoarchitecture in αCT1 and vehicle-control treated skin wounds within the same patient were compared using biopsies from a Phase I clinical trial at 29-day postwounding. The sole effect on scar structure of a range of epidermal and dermal variables examined was that αCT1-treated scars had less alignment of collagen fibers relative to control wounds-a characteristic that resembles unwounded skin. The with-in subject effect of αCT1 on scar collagen order observed in Phase I testing in humans was recapitulated in Sprague-Dawley rats and the IAF hairless guinea pig. Transient increase in histologic collagen density in response to αCT1 was also observed in both animal models. Mouse NIH 3T3 fibroblasts and primary human dermal fibroblasts treated with αCT1 in vitro showed more rapid closure in scratch wound assays, with individual cells showing decreased directionality in movement. An agent-based computational model parameterized with fibroblast motility data predicted collagen alignments in simulated scars consistent with that observed experimentally in human and the animal models. In conclusion, αCT1 prompts decreased directionality of fibroblast movement and the generation of a 3D collagen matrix postwounding that is similar to unwounded skin-changes that correlate with long-term improvement in scar appearance.

Abstract
The aims of this study were to externally validate the OroGrams (oropharyngeal cancer survival calculator) nomogram in a Scottish cohort with high endemic smoking rates, and to compare survival rates with the original validation cohort. A retrospective cohort study in Greater Glasgow and Clyde ENT and OMFS departments was performed to investigate survival outcomes of patients with oropharyngeal squamous cell carcinoma (OPSCC) from January 2012 - December 2017. The main outcome measures were progression-free (PFS) and overall survival (OS), and Kaplan Meier curves. The predictive accuracy of OroGrams was investigated for survival probabilities at one, three, and five years. Smoking and HPV-negative cancer rates were significantly higher in Scottish patients than in the UK consortium cohort. A greater proportion of Scottish patients had advanced UICC8 stages. PFS in patients with HPV-negative cancer appeared better in the Scottish cohort than in the original cohort. Calculated mean standardised Brier scores for PFS and OS were below 0.2 at all three follow-up points, suggesting good overall prognostic accuracy, but there was wide variation between predictive accuracy in individual patients. OroGrams shows prognostic accuracy at one-year follow up in Scotland. The accuracy decreases with longer follow-up periods.

Abstract
Since the mid-20th century, ischemic heart disease has been the world’s leading cause of death. Developing effective clinical cardioprotection strategies would make a significant impact in improving both quality of life and longevity in the worldwide population. Both ex vivo and in vivo animal models of cardiac ischemia/reperfusion (I/R) injury are robustly used in research. Connexin43 (Cx43), the predominant gap junction channel-forming protein in cardiomyocytes, has emerged as a cardioprotective target. Cx43 posttranslational modifications as well as cellular distribution are altered during cardiac reperfusion injury, inducing phosphorylation states and localization detrimental to maintaining intercellular communication and cardiac conduction. Pre- (before ischemia) and post- (after ischemia but before reperfusion) conditioning can abrogate this injury process, preserving Cx43 and reducing cell death. Pre-/post-conditioning has been shown to largely rely on the presence of Cx43, including mitochondrial Cx43, which is implicated to play a major role in pre-conditioning. Posttranslational modifications of Cx43 after injury alter the protein interactome, inducing negative protein cascades and altering protein trafficking, which then causes further damage post-I/R injury. Recently, several peptides based on the Cx43 sequence have been found to successfully diminish cardiac injury in pre-clinical studies.

Abstract
INTRODUCTION Tracheostomy is a common surgical procedure used to create a secure airway in patients, now performed by a variety of specialties, with a notable rise in critical care environments. It is unclear whether this rise is seen in units with large head and neck surgery departments, and how practice in such units compares with the rest of the UK. METHODS A three-year retrospective audit was carried out between anaesthetic, surgical and critical care departments. All tracheostomy procedures were recorded anonymously. RESULTS A total of 523 tracheostomies were performed, 66% of which were in men. The mean patient age was 60 years. The majority (83%) were elective, performed for various indications, while the remaining 17% were emergency tracheostomies performed for pending airway obstruction. A fifth of the tracheostomies were percutaneous procedures. Most emergency tracheostomies (78%) were performed by otolaryngology. Three cricothyroidotomies were performed within critical care and theatres. Complications related to tracheostomy occurred in 47 cases (9%), most commonly lower respiratory tract infection. The mean time to decannulation was 12.8 days. CONCLUSIONS This paper discusses the findings of a comprehensive, multispecialty audit of tracheostomy experience in a large health board, with over 150 tracheostomies performed annually. Elective cases form the majority although there is a significant case series of emergency tracheostomies performed for a range of pathologies. Around a quarter of those requiring tracheostomy ultimately died, mostly as a result of advanced cancer.

Abstract
We present two prescriptions for broadband ($ {\sim} 77 - 252\;{\rm GHz} $), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-format (700 mm diameter) planar and plano-convex elements, the other for densely packed arrays of quasi-optical elements-in our case, 5 mm diameter half-spheres (called "lenslets"). The coatings comprise three layers of commercially available, polytetrafluoroethylene-based, dielectric sheet material. The lenslet coating is molded to fit the 150 mm diameter arrays directly, while the large-diameter lenses are coated using a tiled approach. We review the fabrication processes for both prescriptions, then discuss laboratory measurements of their transmittance and reflectance. In addition, we present the inferred refractive indices and loss tangents for the coating materials and the aluminum oxide substrate. We find that at 150 GHz and 300 K the large-format coating sample achieves $ (97 \pm 2)\% $ transmittance, and the lenslet coating sample achieves $ (94 \pm 3)\% $ transmittance.

Abstract
AIM To determine the accuracy of contrast-enhanced computed tomography (CECT) for nodal extracapsular spread (ECS) and identify predictive radiological signs and clinicopathological features for ECS in unknown-primary head and neck squamous cell cancer (UPHNSCC). MATERIALS AND METHODS The CECT imaging of patients who underwent primary neck dissection for UPHNSCC during 2011-2015 was analysed. The largest pathological-looking node at each radiologically involved level was evaluated in consensus by two head and neck radiologists. Parameters included longest diameter, margin sharpness, haziness in adjacent fat, necrosis, and loss of fat plane with adjacent structures. Independent assessment was also made regarding the presence/absence of ECS. Findings and clinicopathological parameters were correlated with histopathology. RESULTS Thirty-one patients with 39 neck levels had metastatic nodal involvement determined on CECT. Confirmed ECS was found at 26 levels in 23 patients. Sensitivity of radiological assessment for ECS by nodal level was 81-85% (95% confidence interval [CI]=65-93%) and specificity 46-54% (95% CI=19-81%); kappa 0.87. On univariate analysis based on the largest involved node per patient, longest diameter being ≥30 mm (p=0.007), haziness in adjacent fat (p=0.023), increasing age (p=0.006), and more advanced pathological nodal status (p=0.027) were statistically significantly associated with ECS. Haziness and increasing age were independent predictors on multivariate analysis (odds ratio [OR]=26.4 and 1.24). CONCLUSION Expert assessment of ECS on CECT had good sensitivity with excellent interobserver agreement. A longest nodal diameter of ≥30 mm, haziness in the surrounding fat on CECT, advanced pathological nodal status, and advancing patient age were significantly associated with ECS in UPHNSCC patients, findings not previously reported.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
INTRODUCTION Primary care patients with a suspected head and neck cancer are referred through the urgent suspicion of cancer referral pathway. Rates of cancer detection through this pathway are low. Evidence surrounding the pathway of these patients is lacking. This study aimed to determine the outcome of urgent suspicion of cancer referrals for head and neck cancer. METHODS AND METHODS All head and neck cancer urgent suspicion of cancer referrals in NHS Greater Glasgow and Clyde between June 2015 and May 2016 were analysed in regard to their clinical pathway. RESULTS There were 2116 urgent suspicion of cancer referrals in the one-year period. The overall cancer rate was 235 (11.8%), compared with 152 (7.6%) that resulted in a primary head and neck cancer diagnosis. Of the total, 851 (42.6%) were reassured and discharged after one clinic appointment; 536 (26.8%) were followed up for suspected benign pathology and 436 (21.8%) were actively investigated for cancer. CONCLUSION A significant proportion of patients attending urgent suspicion of cancer clinic appointments can be seen and discharged in one clinic appointment, provided there is same day imaging available. Cancer identification rates through urgent suspicion of cancer pathways remain low.

Abstract
The most ubiquitous gap junction protein within the body, connexin 43 (Cx43), is a target of interest for modulating the dermal wound healing response. Observational studies found associations between Cx43 at the wound edge and poor healing response, and subsequent studies utilizing local knockdown of Cx43 found improvements in wound closure rate and final scar appearance. Further preclinical work conducted using Cx43-based peptide therapeutics, including alpha connexin carboxyl terminus 1 (αCT1), a peptide mimetic of the Cx43 carboxyl terminus, reported similar improvements in wound healing and scar formation. Clinical trials and further study into the mode of action have since been conducted on αCT1, and Phase III testing for treatment of diabetic foot ulcers is currently underway. Therapeutics targeting connexin activity show promise in beneficially modulating the human body’s natural healing response for improved patient outcomes across a variety of injuries.

Abstract
Introduction The incidence of deep neck space infection (DNSI) is rising and appears to be related to falling rates of tonsillectomy. The purpose of this study was to assess demographics of patients presenting with DNSI and the financial burden to the National Health Service (NHS). Methods Data were collected retrospectively on patients aged over 16 years admitted to NHS Greater Glasgow and Clyde with DNSI between 2012 and 2016. Demographics, aetiology and use of hospital resources were reviewed. The cost of hospital admissions was calculated using data from NHS Scotland's Information Services Division, the local diagnostics division and the British National Formulary. Results Seventy-four patients were admitted with DNSI during the study period. Forty (54%) were male. The mean age was 44.0 years (range: 16-86 years). The most frequent source of infection was the tonsil (n=30, 40.5%). The most common infective organism was Streptococcus constellatus (n=9, 12.2%). The mean length of stay was 11 days. Fifty-five patients (74.3%) required operative intervention. The mean cost of admission per patient was £5,700 (range: £332-£46,700). Conclusions This study highlights the high cost burden of DNSI to the NHS. The incidence of DNSI in Glasgow has risen over the study period; contributing factors may include the reduced tonsillectomy rate and a reduction in antibiotic prescribing. As the incidence of DNSI continues to rise, there will be an increase in cost to the NHS, which must be planned for.

Abstract
The transmembrane protein Cx43 has key roles in fibrogenic processes including inflammatory signaling and extracellular matrix composition. aCT1 is a Cx43 mimetic peptide that in preclinical studies accelerated wound closure, decreased inflammation and granulation tissue area, and normalized mechanical properties after cutaneous injury. We evaluated the efficacy and safety of aCT1 in the reduction of scar formation in human incisional wounds. In a prospective, multicenter, within-participant controlled trial, patients with bilateral incisional wounds (≥10 mm) after laparoscopic surgery were randomized to receive acute treatment (immediately after wounding and 24 hours later) with an aCT1 gel formulation plus conventional standard of care protocols, involving moisture-retentive occlusive dressing, or standard of care alone. The primary efficacy endpoint was average scarring score using visual analog scales evaluating incision appearance and healing progress over 9 months. There was no significant difference in scar appearance between aCT1- or control-treated incisions after 1 month. At month 9, aCT1-treated incisions showed a 47% improvement in scar scores over controls (Vancouver Scar Scale; P = 0.0045), a significantly higher Global Assessment Scale score (P = 0.0009), and improvements in scar pigmentation, thickness, surface roughness, and mechanical suppleness. Adverse events were similar in both groups. aCT1 has potential to improve scarring outcome after surgery.

Abstract
OBJECTIVE To evaluate diagnostic performance of the emotional domain of the VoiSS questionnaire compared with the Hospital Anxiety and Depression Scale (HADS). DESIGN Cross-sectional questionnaire study. SETTING Tertiary referral centre voice clinic. PARTICIPANTS 210 consecutive voice clinic patients. MAIN OUTCOME MEASURES Screening with VoiSS and HADS questionnaires. Paired comparison, correlation, multinomial logistic regression and receiver-operating characteristic (ROC) curve analysis. RESULTS A total of 177 returned complete data sets. Ninety-six patients (54.2%) had functional dysphonia, and 81 (45.8%) had organic laryngeal disorders. Mean total VoiSS score = 39.7/120 (standard deviation (sd) 22.2). Mean emotional VoiSS subscale = 7.6/22 (sd 7.5). Mean HADS anxiety = 6.5/21 (sd 5.2) and depression mean = 7.1/21 (sd 4.8). There were 35 (20%) borderline anxiety and/or depression scores and 30 (17%) scores considered positive for 'caseness'. There was strong correlation between emotional VoiSS and HADS anxiety (Spearman's Rho = 0.68, P < 0.001) and HADS depression (Spearman's Rho = 0.62, P < 0.001). ROC curve analysis exhibited significant association between emotional VoiSS and HADS 'caseness' (area under curve = 0.88). In addition, functional dysphonia patients had lower mean VoiSS and HADS scores than patients with identifiable laryngeal abnormalities. CONCLUSION The VoiSS emotional subscale strongly correlates with HADS anxiety and depression scores and could be used as a measure of psychological distress. This could allow targeted psychological strategies, without additional psychometric questionnaires. Functional dysphonia has less association with psychological distress than certain organic laryngological disorders.

Abstract
PROBLEM Forward collision warning (FCW) systems are designed to mitigate the effects of rear-end collisions. Driver acceptance of these systems is crucial to their success, as perceived "nuisance" alarms may cause drivers to disable the systems. In order to make customizable FCW thresholds, system designers need to quantify the variation in braking behavior in the driving population. The objective of this study was to quantify the time to collision (TTC) that drivers applied the brakes during car following scenarios from a large scale naturalistic driving study (NDS). METHODS Because of the large amount of data generated by NDS, an automated algorithm was developed to identify lead vehicles using radar data recorded as part of the study. Using the search algorithm, all trips from 64 drivers from the 100-Car NDS were analyzed. A comparison of the algorithm to 7135 brake applications where the presence of a lead vehicle was manually identified found that the algorithm agreed with the human review 90.6% of the time. RESULTS This study examined 72,123 trips that resulted in 2.6 million brake applications. Population distributions of the minimum, 1st, and 10th percentiles were computed for each driver in speed ranges between 3 and 60 mph in 10 mph increments. As speed increased, so did the minimum TTC experience by drivers as well as variance in TTC. Younger drivers (18-30) had lower TTC at brake application compared to older drivers (30-51+), especially at speeds between 40 mph and 60 mph. DISCUSSION This is one of the first studies to use large scale NDS data to quantify braking behavior during car following. The results of this study can be used to design and evaluate FCW systems and calibrate traffic simulation models.

Abstract
WHAT IS KNOWN AND OBJECTIVE To date, there is no evidence to indicate the reliability of how patients self-report their own antibiotic usage in the community. Such data are fundamental in supporting antimicrobial stewardship practices, and so there is a need to determine its accuracy and reliability. COMMENT Patients in the community (n = 476) were required to recollect their antibiotic usage in the past three months. Simultaneously, similar information was obtained by careful extraction from their respective medical notes, which was qualitatively compared with the patient's recollection. Overall, concordance was high (88·1%), but age (<20 and >80 years) and sex (female) were significant factors of reliability. WHAT IS NEW AND CONCLUSION This study suggests that basic self-reporting of antibiotic usage amongst patients is relatively reliable, with increasing accuracy with years until 80 years. Where such information is critical, the current study can help decide who to interview and whose notes to interrogate, in the quest to obtain reliable and accurate information.

Abstract
OBJECTIVE Forward collision warning (FCW) is an active safety system that aims to mitigate the effect of forward collisions by warning the driver of objects in front of the vehicle. Success of FCW relies on how drivers react to the alerts. Drivers who receive too many warnings that they deem as unnecessary-that is, nuisance alarms-may grow to distrust and turn the system off. To reduce the perception of nuisance alarms, FCW systems can be tailored to individual driving styles, but these driving styles must first be characterized. The objective of this study was to characterize differences in braking behavior between age and gender groups in car-following scenarios using data from the 100-Car Naturalistic Driving Study. METHODS The data source for this study was the 100-Car Naturalistic Driving Study, which recorded the driving of 108 primary drivers for approximately a year. Braking behavior was characterized in terms of time to collision (TTC) at brake application, a common metric used in the design of warning thresholds of FCW. Because of the large volume of data analyzed, the TTC at which drivers braked during car-following situations was collected via an automated search algorithm. The minimum TTC for each vehicle speed 10 mph increment from 10 mph to 80 mph was recorded for each driver. Mixed model analysis of variance was used to examine the differences between age and gender groups. RESULTS In total, 527,861 brake applications contained in 11,503 trips were analyzed. Differences in TTC at braking were statistically significant for age and gender (P<.01 for both cases). Males age 18-20 (n=7) had the lowest average minimum TTC at braking of 2.5±0.8 s, and females age 31-50 (n=6) had the highest average minimum TTC at braking of 6.4±0.9 s. On average, women (n=32) braked at a TTC 1.3 s higher than men (n=52). Age was a statistically significant factor for TTC at braking between participants under 30 (n=42) and participants over 30 (n=42), with the latter braking 1.7 s on average before the former. No statistical significance was found between ages 18-20 (n=15) and 21-30 (n=27) or between ages 31-50 (n=23) and 50+(n=19). CONCLUSIONS There are clear statistical differences in TTC at braking for both gender and those over 30 vs. those under 30. Designers of FCW systems can use the data found in this study to tailor alert timings to the target demographic of a vehicle when designing forward collision warning systems. Appropriate alert timings for FCW systems will maximize effectiveness in collision reduction and mitigation.
