Abstract
We present a reconfigurable topological photonic system consisting of a 2D lattice of coupled ring resonators, with two sublattices of site rings coupled by link rings, which can be accurately described by a tight-binding model. Unlike previous coupled-ring topological models, the design is translationally invariant, similar to the Haldane model, and the nontrivial topology is a result of next-nearest couplings with nonzero staggered phases. The system exhibits a topological phase transition between trivial and spin Chern insulator phases when the sublattices are frequency detuned. Such topological phase transitions can be easily induced by thermal or electro-optic modulators, or nonlinear cross phase modulation. We use this lattice to design reconfigurable topological waveguides, with potential applications in on-chip photon routing and switching.

Abstract
A 44-year-old man with background history of diffuse cutaneous systemic sclerosis and dilated cardiomyopathy receiving immunosuppressive medications, presented with a 2-month history of cough and streaky hemoptysis. Clinicoradiological features were consistent with an endotracheal mass. Subsequently, the patient developed nodular skin lesions and the tracheal mass increased in size causing central airway obstruction. This clinicopathologic conference discusses the clinical and radiological differential diagnoses of such a clinical presentation and their management options.

Abstract
OBJECTIVES: To evaluate the clinical effectiveness of two methods of application of a mild one-step self-etch adhesive and composite resin as compared with a resin-modified glass ionomer cement (RMGIC) control restoration in noncarious cervical lesions (NCCLs). METHODS: A total of 294 restorations were placed in 56 patients, 98 in each one of the following groups: 1) G-Bond active application combined with Solare-X composite resin (A-1SEA), 2) G-Bond passive application combined with Solare-X composite resin (P-1SEA), and 3) GC II LC RMGIC. The restorations were evaluated at baseline and after six, 12, and 18 months according to the FDI criteria for fractures/retention, marginal adaptation, marginal staining, postoperative sensitivity, and secondary caries. Cumulative failure rates were calculated for each criterion at each recall period. The effect of adhesive, method of application, and recall period were assessed. The Kruskal-Wallis test for intergroup comparison and Friedman and Wilcoxon signed ranks tests for intragroup comparison were used for each criterion ( α=0.05). RESULTS: The retention rates at 18 months were 93.26% for the A-1SEA group, 86.21% for the P-1SEA group, and 90.91% for the RMGIC group. The active application improved the retention rates compared with the passive application of mild one-step self-etch adhesive; however, no statistically significant difference was observed between the groups. Marginal staining was observed in 13 restorations (1 in A-1SEA, 4 in P-1SEA, and 8 in RMGIC) with no significant difference between the groups. The RMGIC group showed a significant increase in marginal staining at 12 and 18 months from the baseline. There was no significant difference between the groups for marginal adaptation, secondary caries, or postoperative sensitivity. CONCLUSION: Within the limitations of the study, we can conclude that mild one-step self-etch adhesive followed by a resin composite restoration can be an alternative to RMGIC with similar retention and improved esthetics in restoration of NCCLs. Agitation could possibly benefit the clinical performance of mild one-step self-etch adhesives, but this study did not confirm that the observed benefit was statistically significant.

Abstract
Background and Objectives: No previous study has compared different concentrations of lignocaine for topical anesthesia during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this pilot study, we compared 1% versus 2% lignocaine for topical airway anesthesia during EBUS-TBNA. Methods: In this double-blind, randomized trial, subjects were randomized to receive either 1% or 2% lignocaine for “spray-as-you-go” administration. All received combined moderate intravenous sedation (midazolam and fentanyl). Ten percent pharyngeal lignocaine spray (two sprays) and nebulized lignocaine (2.5 ml of 4% solution) were administered to all subjects. Administration of additional lignocaine was allowed at operator's discretion. The primary endpoints were operator-rated overall procedural satisfaction and cough, each assessed on visual analog scale (VAS), while the secondary outcomes included patient-rated faces pain scale scores, cumulative lignocaine dose, number of subjects receiving lignocaine >8.2 mg/kg, doses of midazolam/fentanyl between groups, and adverse events during procedure. Results: The mean (standard deviation [SD]) VAS scores for operator-rated procedure satisfaction were 64.2 (25.6) and 68.7 (23.7) in 1% and 2% group, respectively (P = 0.35). The median (interquartile range) VAS scores for operator-rated cough were 48.4 (23.9–69.9) in 1% group and 38.7 (18.6–69.5) in 2% group (P = 0.24). The mean [SD] cumulative lignocaine received in the 2% lignocaine group (248.6 [29.1] mg) was significantly greater than in 1% lignocaine group (178.5 [14.6] mg) (P < 0.01). Conclusion: One percent lignocaine is equally efficacious as 2% lignocaine for topical anesthesia during EBUS-TBNA, at a significantly lower cumulative lignocaine dose.

Abstract
Transbronchial lung biopsy (TBLB) is commonly utilized for diagnosis of diffuse parenchymal lung diseases. TBLB has a high yield in granulomatous interstitial lung diseases like sarcoidosis, but small size of biopsies limits its utility in idiopathic interstitial pneumonia. Surgical lung biopsy provides large size tissue, but there is associated morbidity, longer hospital stay, the risk of air leak, and mortality. Cryoprobe-TBLB, a relatively newer diagnostic procedure, provides larger biopsies than TBLB that are usually crush artifact free and enable the pathologist to provide diagnosis with greater confidence. We describe our technique of performing cryoprobe-TBLB.

Abstract
Various studies comparing operative and non-operative intervention for displaced intrarticular calcaneal fractures have reported conflicting findings in the past. The objective of this meta-analysis was to compare the efficacy and safety of open reduction and internal fixation (ORIF) vis-a-vis conservative management. Relevant randomized controlled trials (RCTs) comparing operative and non-operative intervention for displaced intraarticular calcaneal fractures were assessed and included in this meta-analysis. Data was extracted independently and methodological quality was further assessed. The inclusion criteria of this meta-analysis were: randomized controlled trials comparing operative with non-operative intervention for displaced intra-articular fractures of calcaneum and reporting atleast one of the main outcomes as failure to resume pre-injury work, residual pain and other complications. Eight randomized controlled trials fulfilled the criteria for this meta-analysis. Pooled results showed that patients managed conservatively failed to resume pre-injury work (RR 0.60, 95% CI = 0.37-0.98, P = 0.04). However operative intervention was associated with more complications (RR 1.74, 95% CI = 1.28 to 2.37, P = 0.0005). There was no statistically significant difference in residual pain (RR 0.73 95% CI = 0.40-1.36, P = 0.33) and reoperation (RR = 0.75, 95% CI = 0.48-1.16, P = 0.20) between the two groups. Surgery can benefit patients with calcaneal fracture and increases their likelihood to resume pre-injury work. However, the complication rates are significantly higher in the operative group. Since the included trials have used different scores to measure patient outcomes, hence little effective data could.

Abstract
A 26-year-old smoker male presented with a history of sudden onset dyspnea and right-sided chest pain. Chest radiograph revealed large right-sided pneumothorax which was managed with tube thoracostomy. High-resolution computed tomography thorax revealed multiple lung cysts, and for a definite diagnosis, a video-assisted thoracoscopic surgery-guided lung biopsy was performed followed by pleurodesis. This clinicopathologic conference discusses the clinical and radiological differential diagnoses, utility of lung biopsy, and management options for patients with such a clinical presentation.

Abstract
Objective To evaluate the extent to which stillbirths affect international comparisons of preterm birth rates in low‐ and middle‐income countries. Design Secondary analysis of a multi‐country cross‐sectional study. Setting 29 countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. Population 258 215 singleton deliveries in 286 hospitals. Methods We describe how inclusion or exclusion of stillbirth affect rates of preterm births in 29 countries. Main outcome measures Preterm delivery. Results In all countries, preterm birth rates were substantially lower when based on live births only, than when based on total births. However, the increase in preterm birth rates with inclusion of stillbirths was substantially higher in low Human Development Index (HDI) countries [median 18.2%, interquartile range (17.2–34.6%)] compared with medium (4.3%, 3.0–6.7%), and high‐HDI countries (4.8%, 4.4–5.5%). Conclusion Inclusion of stillbirths leads to higher estimates of preterm birth rate in all countries, with a disproportionately large effect in low‐HDI countries. Preterm birth rates based on live births alone do not accurately reflect international disparities in perinatal health; thus improved registration and reporting of stillbirths are necessary. Tweetable abstract Inclusion of stillbirths increases preterm birth rates estimates, especially in low‐HDI countries. Inclusion of stillbirths increases preterm birth rates estimates, especially in low‐HDI countries.
