Abstract
Biomass burning aerosol (BBA) emissions in the Coupled Model Intercomparison Project phase 6 (CMIP6) historical forcing fields have enhanced temporal variability during the years 1997–2014 compared to earlier periods. Recent studies document that the corresponding inhomogeneous shortwave forcing over this period can cause changes in clouds, permafrost, and soil moisture, which contribute to a net terrestrial Northern Hemisphere warming relative to earlier periods. Here, we investigate the ocean response to the hemispherically asymmetric warming, using a 100-member ensemble of the Community Earth System Model version 2 Large Ensemble forced by two different BBA emissions (CMIP6 default and temporally smoothed over 1990–2020). Differences between the two subensemble means show that ocean temperature anomalies occur during periods of high BBA variability and subsequently persist over multiple decades. In the North Atlantic, surface warming is efficiently compensated for by decreased northward oceanic heat transport due to a slowdown of the Atlantic meridional overturning circulation. In the North Pacific, surface warming is compensated for by an anomalous cross-equatorial cell (CEC) that reduces northward oceanic heat transport. The heat that converges in the South Pacific through the anomalous CEC is shunted into the subsurface and contributes to formation of long-lasting ocean temperature anomalies. The anomalous CEC is maintained through latitude-dependent contributions from narrow western boundary currents and basinwide near-surface Ekman transport. These results indicate that interannual variability in forcing fields may significantly change the background climate state over long time scales, presenting a potential uncertainty in CMIP6-class climate projections forced without interannual variability.
Two Marine Heatwave (MHW) Variants under a Basinwide MHW Conditioning Mode in the North Pacific and Their Atlantic Associations

Published: September 2023

Abstract
During 2013–16 and 2018–22, marine heatwaves (MHWs) occurred in the North Pacific, exhibiting similar extensive coverage, lengthy duration, and significant intensity but with different warming centers. The warming center of the 2013–16 event was in the Gulf of Alaska (GOA), while the 2018–22 event had warming centers in both the GOA and the coast of Japan (COJ). Our observational analysis indicates that these two events can be considered as two MHW variants induced by a basinwide MHW conditioning mode in the North Pacific. Both variants were driven thermodynamically by atmospheric wave trains propagating from the tropical Pacific to the North Pacific, within the conditioning mode. The origin and propagating path of these wave trains play a crucial role in determining the specific type of MHW variant. When a stronger wave train originates from the tropical central (western) Pacific, it leads to the GOA (COJ) variant. The cross-basin nature of the wave trains enables the two MHW variants to be accompanied by a tripolar pattern of sea surface temperature anomalies in the North Atlantic but with opposite phases. The association of these two MHW variants with the Atlantic Ocean also manifests in the decadal variations of their occurrence. Both variants tend to occur more frequently during the positive phase of the Atlantic multidecadal oscillation but less so during the negative phase. This study underscores the importance of cross-basin associations between the North Pacific and North Atlantic in shaping the dynamics of North Pacific MHWs.
Opposite Skills of ENGPI and DGPI in Depicting Decadal Variability of Tropical Cyclone Genesis over the Western North Pacific

Abstract
The genesis potential index (GPI) has been used widely to estimate the influence of large-scale conditions on tropical cyclone (TC) genesis. Here we find that two GPIs, the Emanuel–Nolan GPI (ENGPI) and the dynamic GPI (DGPI), show opposite skills in quantifying decadal variability of TC genesis in the western North Pacific (WNP). During 1979–2020, ENGPI shows a reverse decadal variation to the WNP TC genesis with a significant negative correlation of −0.61, while DGPI can reasonably reproduce the decadal variation of the WNP TC genesis with a significant correlation of 0.66. The opposite skills of the two indices arise from the opposed effects of dynamic and thermodynamic parameters on TC genesis induced by a WNP anomalous cyclonic circulation that controls the decadal variation of TC genesis. On the one hand, the cyclonic circulation leads to favorable dynamical conditions including ascending motion, cyclonic vorticity, and weakened vertical shear, and thus tends to increase the DGPI. On the other hand, the cyclonic circulation leads to unfavorable thermodynamical conditions (decreased maximum potential intensity and midlevel humidity) that tends to decrease the ENGPI. As a result, the DGPI and ENGPI are reversely evolved and eventually lead to their opposite correlation between TC genesis. The significant positive correlation between DGPI and TC genesis suggests a critical role in the large-scale dynamical control of the decadal variability of the WNP TC genesis.

Significance Statement
Tropical cyclones (TCs) account for one-third of the deaths and economic losses from weather-, climate-, and water-related disasters. Understanding variations in TC activity from the perspective of large-scale conditions is of great importance to seasonal forecasting and disaster mitigation. Here we find that two genesis potential indexes (GPIs), the Emanuel–Nolan GPI (ENGPI) and dynamic GPI (DGPI), show opposite skill in quantifying decadal variability of TC genesis in the western North Pacific (WNP). The opposite skills of the two indices arise from the opposed effects of dynamic and thermodynamic parameters on TC genesis. The result suggests a critical role of large-scale dynamic control in the decadal variability of TC genesis in the WNP.

Authors: Wu Meixia , Lou Zhengcai 
Published: September 2023

Objective: The objective of this study was to evaluate the graft success rate and hearing outcome of modified cartilage inlay graft technique for repairing large perforations under local anesthesia. Study Design: Prospective case series. Methods and Materials: We performed a prospective study in 31 patients with large perforations who underwent endoscopic local anesthesia-based modified cartilage inlay graft technique with no raising of the squamous epithelium and no rimming of the perforation margins. The graft outcomes and complications were evaluated at 6 and 24 months postoperatively. Results: Thirty-one patients (31 ears) were included in this study. The mean operation time was 42.3 ± 2.6 (ranged 36-51) minutes. The visual analog scale pain scores at intraoperative and 2 and 48 hours postoperatively were, respectively, 2.6 ± 0.6, 1.4 ± 0.2, and 0.6 ± 0.1. The graft success rate was 100.0% (31/31) at 6 months after surgery. However, only 25 (80.6%, 25/31) patients completed a 2-year follow-up and performed a temporal bone CT examination; re-perforation was seen in 2 patients, the graft success rate was 92.0% (23/25). CT revealed the well-developed pneumatization of the mastoids and middle ear in all the patients. Nevertheless, 1 (1/25, 8.0%) patient developed a graft epithelial inclusion cyst, which was removed by endoscope in the outpatient setting. The mean preoperative air bone gap (ABG) was 23.1 ± 4.3 dB, while the mean postoperative ABG after 6 months was 14.9 ± 2.6 dB; the difference between these values was significant ( P < .05; Wilcoxon’s signed-rank test), and the functional success rate was 93.5% (29/31). Conclusion: Endoscopic modified cartilage “inlay” graft technique with no raising the squamous epithelium and no rimming the perforation is a minimally invasive technique with a short operative time and satisfying success rate for closure of large perforations under local anesthesia.

Background Computed tomography angiography (CTA) is a reliable, non-invasive screening method for diagnosing panvascular disease. By using low contrast agent volume, CTA imaging enables one-stop multi-organ scanning, thereby minimizing the potential risk of contrast-induced nephropathy in patients with impaired renal function. Purpose To evaluate the feasibility of one-stop CTA following a heart rate (HR)-based protocol using a low volume of contrast medium (CM) for examination of the coronary, carotid and cerebrovascular arteries. Material and Methods Sixty patients undergoing coronary carotid, and cerebrovascular CTA after a single injection of CM were recruited and randomly divided into two groups. Group A (n = 30) underwent CTA following a traditional protocol. The timing of the scans in Group B (n = 30) was determined according to the patient's HR. Results The CT values for the thoracic aorta (432.2 ± 104.28 HU), anterior cerebral artery (303.96 ± 99.29 HU), and right coronary artery (366.70 ± 85.10 HU) in Group A did not differ significantly from those in Group B (445.80 ± 106.13, 293.73 ± 75.25 and 344.13 ± 111.04 HU, respectively). The qualities of most of the scanned images for both groups were scored as 3 or 4 (on a five-point scale). The radiation dose and the volume of CM were significantly higher in Group A (303.05 ± 110.95 mGy) (100 mL) than in Group B (239.46 ± 101.12 mGy) (50 mL). Conclusion The radiation dose and volume of CM were significantly reduced in CTA following the HR-based protocol. The personalized administration of CM also simplified the scanning process.

Published: September 2023

Background Pulmonary nodules are an early imaging indication of lung cancer, and early detection of pulmonary nodules can improve the prognosis of lung cancer. As one of the applications of machine learning, the convolutional neural network (CNN) applied to computed tomography (CT) imaging data improves the accuracy of diagnosis, but the results could be more consistent. Purpose To evaluate the diagnostic performance of CNN in assisting in detecting pulmonary nodules in CT images. Material and Methods PubMed, Cochrane Library, Web of Science, Elsevier, CNKI and Wanfang databases were systematically retrieved before 30 April 2023. Two reviewers searched and checked the full text of articles that might meet the criteria. The reference criteria are joint diagnoses by experienced physicians. The pooled sensitivity, specificity and the area under the summary receiver operating characteristic curve (AUC) were calculated by a random-effects model. Meta-regression analysis was performed to explore potential sources of heterogeneity. Results Twenty-six studies were included in this meta-analysis, involving 2,391,702 regions of interest, comprising segmented images with a few wide pixels. The combined sensitivity and specificity values of the CNN model in detecting pulmonary nodules were 0.93 and 0.95, respectively. The pooled diagnostic odds ratio was 291. The AUC was 0.98. There was heterogeneity in sensitivity and specificity among the studies. The results suggested that data sources, pretreatment methods, reconstruction slice thickness, population source and locality might contribute to the heterogeneity of these eligible studies. Conclusion The CNN model can be a valuable diagnostic tool with high accuracy in detecting pulmonary nodules.

Résumé Objectif L’objectif de cette étude est de comprendre les problèmes de la prise en charge des troubles psychologiques chez les personnes migrantes à partir de l’expérience des Médecins Généralistes Méthode Une étude qualitative a été réalisée auprès de médecins généralistes interrogés sur un mode semi-directif. Nous avons choisi la méthode de comparaison continue et l'approche phénoménologique pragmatique de Peirce, afin d’explorer l'expérience vécue. Résultats Treize entretiens réalisés ont permis de faire émerger quatre catégories phénoménologiques : (1) La migration était un itinéraire de l’expérience de la souffrance mentale du départ jusqu’à l’arrivée, à l’origine des TPPM avec nécessité d’un suivi spécialisé. (2) L’accueil insuffisant à l’arrivée du migrant, avec un parcours administratif compliqué et des conditions sociétales et environnementales insécures aggravaient leur précarité rendant leur suivi difficile. (3) La migration était un itinéraire transculturel dans lequel le langage, les attitudes et les représentations de chacun brouillaient la compréhension des symptômes et des soins et donc la communication professionnelle. (4) Les médecins généralistes impréparés considéraient la consultation du migrant inadaptée, chronophage et complexe. Ils pointaient la nécessité d’un dispositif coordonné avec une prise en charge globale pluridisciplinaire. La saturation des données a été atteinte. Il y a eu triangulation de trois chercheurs. Conclusion Ce travail expose les difficultés rencontrées par les MG confrontés aux patients migrants en France. Ils se sentent démunis devant la nature des troubles exprimés et ressentent une inadéquation entre la relation difficile à mettre en place et celle de leur exercice habituel, même lorsque l’expérience professionnelle auprès de cette population est développée. Ils témoignent un besoin de modèles coordonnés de prises en charge, financés par les politiques.

Objetive To analyze if differences in lifestyle and environment between coastal and inland areas are associated with differences in frequency of orofacial cleft types. Design Populational cross-sectional study. Setting All live borns with orofacial cleft registered at Brazilian Live Birth Information System between 1999 and 2020. Participants 33,699 live borns with orofacial cleft. Intervention Data from borns with orofacial cleft were collected at Brazilian Live Birth Information System. Main outcome measure Differences in frequencies between the cleft types and covariates were determined using chi-square. Bivariate analysis was done to obtain the prevalence ratio of types of clefts by geographic origin. Multiple logistic regression analysis was used to determine adjusted odds ratios, controlling for covariates, establishing a significance level of p value <0.05. Results The frequency of cleft types was statistically significant different according to geographic origin (inland x coast). For syndromic clefts, the prevalence ratio for cleft lip with/without palate was 3.6 times higher inland (p value = 0.000). Regarding non-syndromics, the prevalence ratio for cleft lip with/without palate was two times higher inland (p value = 0.000). Logistic regression suggested cleft lip with/without palate was 6.33 more likely to occur in inland regions (p value = 0.000). Conclusion Geographic origin was associated with the type of cleft in Brazil, with a higher prevalence of cleft lip with/without palate in inland areas, compared to cleft palate, which was higher in the coast.

Published: September 2023

Objective: To review treatment options and updates that exist for the management of paroxysmal supraventricular tachycardia (PSVT). Data Sources: A literature search of PubMed was performed including articles from 1974 to June 2023 using the terms: arrhythmias, adenosine, verapamil, diltiazem, esmolol, propranolol, metoprolol, beta-blockers, amiodarone, PSVT, synchronized cardioversion, methylxanthines, dipyridamole, pediatrics, heart transplant, and pregnancy. Primary literature and guidelines were reviewed. Study Selection and Data Extraction: Studies were considered if they were available in English and conducted in humans. Data Synthesis: PSVT is a subset of supraventricular tachycardia (SVT) that presents as a rapid, regular tachycardia with an abrupt onset and termination. Due to frequent emergency department (ED) visits annually with symptoms of PSVT, appropriate and efficient management of these patients is vital. This review provides an overview of the pathophysiology of PSVT, while also describing the literature behind nonpharmacologic and pharmacologic management of PSVT. Relevance to Patient Care and Clinical Practice: This review describes new literature regarding the improved success of the modified Valsalva maneuver as a nonpharmacologic therapy in PSVT. In addition, it describes a new technique in administration of adenosine that has improved outcomes, defines dose adjustments needed for drug interactions with adenosine, compares the utilization of nondihydropyridine calcium channel blockers with adenosine, and provides management recommendations for patients in special populations. Conclusions: With high annual rates of ED visits for SVT, providers should be aware of the data behind management and modifications of therapy based on patient-specific factors (ie, patient preference, pharmacokinetics/pharmacodynamics, drug interactions, and special populations).

Published: September 2023

Background: Clozapine is the most effective antipsychotic with respect to the incidence of discontinuation and is indicated for treatment-resistant schizophrenia. Although the recommendation for clozapine administration is divided dosing, once-daily dosing of clozapine is commonly prescribed in many countries. However, there is currently no clinical data comparing all-cause discontinuation between the 2 methods of administration of clozapine. Objectives: To compare the all-cause discontinuation and safety of clozapine administration between once-daily and divided dosing regimens. Methods: This was a retrospective cohort study. Participants were patients with treatment-resistant schizophrenia who had received 300 to 600 mg/day of clozapine for at least 3 months. Data were collected from outpatient medical records at Somdet Chaopraya Institute of Psychiatry. Eligible patients were classified into 2 groups: once-daily dosing and divided dosing. The primary outcome was the all-cause discontinuation rate between groups. The duration of the study was 2 years. Results: One hundred eighteen patients were included and analyzed in this study (once-daily dosing group: n = 58; divided dosing group: n = 60). There was no significant difference in all-cause discontinuation between the 2 groups (odds ratio 1.03; 95% confidence interval: [0.28, 3.79]: P = 1.00), or adverse events between groups. Conclusion and Relevance: In patients with treatment-resistant schizophrenia, there were no significant differences in effectiveness or safety between once-daily and divided dosing of clozapine. Further prospective studies with larger sample sizes are required to confirm these findings.

Purpose/Aim To report the birth prevalence and natural history of congenital corneal opacities among a population-based cohort of children. Materials and methods The medical records of patients <5 years diagnosed with a congenital onset corneal opacity while residing in Olmsted County, Minnesota, from January 1, 1977, through December 31, 2016, were retrospectively reviewed. Results Fourteen patients were diagnosed with a congenital corneal opacity during the 40-year study period for a birth prevalence of 1 in 5188 live births. The mean age at diagnosis was 7.5 months (range 0–48 months) and 9 (64.3%) were males. Four patients had congenital glaucoma, 4 had limbal dermoids, 2 had sclerocornea, and 1 patient each had Descemet's tear from birth trauma, herpes simplex virus type 1 keratitis, corneal leukoma, and an undiagnosed scar. Six (42.8%) patients required treatment for their underlying corneal opacity including the four patients with congenital glaucoma. The other 8 (57.1%) patients had a clear central axis. Four (28.6%) of 14 patients required amblyopia therapy, and 4 (28.6%) developed strabismus. Four (28.6%) patients had associated systemic conditions. During a mean follow up of 5.4 years (range 1.3–27.0 years), the median best corrected visual acuity (BCVA) was logmar 0.16 (20/25) (range 20/20-hand motion) with one patient with unilateral BCVA less than 20/60 and one patient with bilateral BCVA less than 20/60. Conclusions In this 40-year cohort, congenital corneal opacities were relatively rare and the result of a variety of disorders. Although amblyopia and strabismus occurred commonly, most patients had good visual outcomes.
Prevalence and assessment of frailty in interstitial lung disease - a systematic review and meta-analysis

Published: September 2023

Background Frailty is a multisystem dysregulation that challenges homeostasis and increases vulnerability towards stressors. In patients with interstitial lung diseases (ILD) frailty is associated with poorer lung function, greater physical impairment, and higher symptom burden. Our understanding of the prevalence of frailty in ILD and consequently its impact on the ILD population is limited. Objective and Methods We aimed to systematically review frailty assessment tools and to determine frailty prevalence across different ILD cohorts. Meta-analyses were used to calculate the pooled prevalence of frailty in the ILD population. Results We identified 26 studies (15 full-texts, 11 conference abstracts) including a total of 4614 patients with ILD. The most commonly used frailty assessment tools were the Fried Frailty Phenotype (FFP), the Short Physical Performance Battery (SPPB), and the cumulative Frailty Index (FI). Data allowed for meta-analyses of FFP and SPPB prevalence. The pooled prevalence of frailty was 35% (95% CI 25%–45%) by FFP, and 19% (95% CI 12%–28%) by SPPB. Conclusions Frailty is common in ILD, with considerable variability of frailty prevalence depending on the frailty assessment tool used. These findings highlight the importance of frailty in ILD and the need for a standardized approach to frailty assessment in this population.
