<h3>Background</h3>Clinical remission has emerged as an important treatment goal in severe asthma; however, studies have reported variable attainment due to differences in study populations, definitions, and methods. We aimed to perform a systematic review and meta-analysis of clinical remission attainment, definitions, and correlates among patients with severe asthma who have been treated with biologics.<h3>Methods</h3>In this systematic review and meta-analysis, we searched Web of Science, Embase, and MEDLINE, using the keywords “asthma” and “remission”, for studies published between database inception and June 13, 2024, that reported clinical remission among patients with severe asthma treated with biologics. Studies were eligible for inclusion in both the systematic review and meta-analysis if they were published in English language peer-reviewed journals and reported rates of clinical remission for patients treated with biologics for severe asthma. There were no limitations by study design. Two reviewers independently screened identified papers (AS and CR), with disagreements resolved through consensus or referral to a third reviewer (JB). Study-level data on study characteristics, clinical remission definitions, clinical remission attainment, and the potential correlates of clinical remission were extracted independently by two reviewers (AS and CR) using Covidence. We defined a three-component definition of clinical remission, which included use of maintenance oral corticosteroids, exacerbations, and asthma symptom burden, and a four-component definition, which additionally included lung function. We meta-analysed the rate of attainment of clinical remission and assessed the correlates of clinical remission using DerSimonian-Laird random-effects models. Statistical heterogeneity was assessed using the <em>I</em><sup>2</sup> statistic. This study was registered with PROSPERO, CRD42024507233.<h3>Findings</h3>Our search identified 3014 potentially eligible studies, of which 1812 were screened. 25 studies were included, which reported 28 analyses of clinical remission attainment. 68 definitions of clinical remission were identified, of which 48 were unique. Little consensus was found between studies in terms of the clinical remission definition, particularly for symptoms and lung function. Eight analyses used the three-component definition of clinical remission and 25 used the four-component definition. The pooled proportion of patients who attained clinical remission was 38% (95% CI 29–47; <em>I</em><sup>2</sup>=93%) for the three-component definition and 30% (27–34; <em>I</em><sup>2</sup>=83%) for the four-component definition. Several pulmonary factors were associated with lower clinical remission rates, including worse FEV<sub>1</sub> (odds ratio 0·09 [95% CI 0·01–0·92]; <em>I</em><sup>2</sup>=87%), worse asthma symptoms (0·23 [0·17–0·33]; <em>I</em><sup>2</sup>=0%), longer asthma duration (0·49 [0·32–0·76]; <em>I</em><sup>2</sup>=22%), an

Two late 18th century manuscripts
Both of the manuscripts we feature here were written by students hearing the lectures of famous authors, but whose advice on thoracentesis is previously unknown.

Discussion
This Spotlight suggests that until the 18th century, doctors carried out thoracentesis largely in accordance with Hippocrates' recommendations to make the incision low in the chest. The question arose as to whether the approach should be anterior or posterior. We can see that at least two reputed doctors with considerable anatomical knowledge, Astruc and Bichat, raised the question of the drainage technique, with particular reference to the surgical approach.

The recent discovery of superconductivity and magnetism in trilayer rhombohedral graphene (RG) establishes an ideal, untwisted platform to study strong correlation electronic phenomena. However, the correlated effects in multilayer RG have received limited attention, and, particularly, the evolution of the correlations with increasing layer number remains an unresolved question. Here we show the observation of layer-dependent electronic structures and correlations—under surprising liquid nitrogen temperature—in RG multilayers from 3 to 9 layers by using scanning tunnelling microscopy and spectroscopy. We explicitly determine layer-enhanced low-energy flat bands and interlayer coupling strengths. The former directly demonstrates the further flattening of low-energy bands in thicker RG, and the latter indicates the presence of varying interlayer interactions in RG multilayers. Moreover, we find significant splittings of the flat bands, ranging from ~50 meV to 80 meV, at 77 K when they are partially filled, indicating the emergence of interaction-induced strongly correlated states. Particularly, the strength of the correlated states is notably enhanced in thicker RG and reaches its maximum in the six-layer, validating directly theoretical predictions and establishing abundant new candidates for strongly correlated systems. Our results provide valuable insights into the layer dependence of the electronic properties in RG and demonstrate it as a suitable system for investigating robust and highly accessible correlated phases.

Tuning the band gap of perovskites toward the ideal band gap enables the enhancement of the power conversion efficiency (PCE) of perovskite solar cells (PSCs). Here, we demonstrate that the optical band-gap narrowing can be achieved by employing the excitonic absorption in perovskites through tuning their exciton binding energy (Eb), which directly leads to a photocurrent gain and hence improves the PCE of PSCs. With combined theoretical and experimental studies, it is revealed that the Eb is deeply correlated with the density of vacancy defects in perovskites due to their potential screening effect. Using the precursor engineering, we enhance the Eb by decreasing the density of vacancy defects in perovskites films. As a result, the improved excitonic absorption in formamidinium lead iodide (FAPbI3) obviously broadens the spectral response and thus boosts the efficiency of the champion PSC up to 26.31% (certified 26.09%), mainly due to an enhanced photocurrent.

In conventional n-i-p perovskite solar cells, unsolved issues persist, particularly concerning notorious performance degradation under prolonged heat exposure at 85°C. By reducing the concentration of 4-tert-butylpyridine (tBP) and lithium bis(trifluoromethanesulfonyl)imide and adjusting their molar ratio to one, we achieved a dramatic increase in the heat stability of the PSC while boosting its power conversion efficiency (PCE). The formation of a 1:1 Li+-tBP complex was crucial for preventing free tBP molecules in the hole-transporting layer (HTL), suppressing the de-doping of the p-type HTL by tBP and the release of tBP vapor under heat stress. Consequently, the PSCs accomplished a PCE of 26.18% (certified 26.00%) while demonstrating remarkable resilience to heat exposure at 85°C due to the raised glass transition temperature of the HTL. Furthermore, a perovskite solar mini-module with an aperture area of 25 cm2 achieved a PCE of 23.29%, highlighting their potential for commercial PSC deployment.
