This double-blind study randomly assigned adults with obesity (or overweight and with one or more weight-related coexisting conditions) without diabetes to 68 weeks of once-weekly subcutaneous semaglutide (2.4 mg) or placebo, plus lifestyle intervention. Semaglutide therapy was associated with sustained, clinically relevant weight reduction.

In this trial of a recombinant VZV glycoprotein E subunit vaccine with the adjuvant AS01 B , the risk of herpes zoster and postherpetic neuralgia is shown to be significantly lower in association with the vaccine than with placebo among persons 70 years of age or older. Herpes zoster, or shingles, results from the reactivation of latent varicella–zoster virus (VZV) and typically manifests as a vesicular, painful dermatomal rash. 1 , 2 The most common complication of herpes zoster, postherpetic neuralgia, manifests as chronic neuropathic pain that can greatly limit daily activities. 1 , 3 – 6 The overall incidence of herpes zoster is 2.0 to 4.6 cases per 1000 person-years but increases with age to 10.0 to 12.8 per 1000 person-years among persons 80 years of age or older. 7 – 10 Similarly, the incidence of postherpetic neuralgia also increases with age. 10 – 13 Antiviral therapy can reduce the duration of herpes zoster rash . . .

Weight reduction has been shown to alleviate symptoms of osteoarthritis of the knee, including pain. The effect of glucagon-like peptide-1 receptor agonists on outcomes in knee osteoarthritis among persons with obesity has not been well studied. We conducted a 68-week, double-blind, randomized, placebo-controlled trial at 61 sites in 11 countries. Participants with obesity (a body-mass index [BMI; the weight in kilograms divided by the square of the height in meters] of ≥30) and a clinical and radiologic diagnosis of moderate knee osteoarthritis with at least moderate pain were randomly assigned, in a 2:1 ratio, to receive once-weekly subcutaneous semaglutide (2.4 mg) or placebo, in addition to counseling on physical activity and a reduced-calorie diet. The primary end points were the percentage change in body weight and the change in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score (on a scale of 0 to 100, with higher scores reflecting worse outcomes) from baseline to week 68. A key confirmatory secondary end point was the physical-function score on the 36-Item Short Form Health Survey (SF-36), version 2 (on a scale of 0 to 100, with higher scores indicating greater well-being). A total of 407 participants were enrolled. The mean age was 56 years, the mean BMI 40.3, and the mean WOMAC pain score 70.9. A total of 81.6% of the participants were women. The mean change in body weight from baseline to week 68 was -13.7% with semaglutide and -3.2% with placebo (P<0.001). The mean change in the WOMAC pain score at week 68 was -41.7 points with semaglutide and -27.5 points with placebo (P<0.001). Participants in the semaglutide group had a greater improvement in SF-36 physical-function score than those in the placebo group (mean change, 12.0 points vs. 6.5 points; P<0.001). The incidence of serious adverse events was similar in the two groups. Adverse events that led to permanent discontinuation of the trial regimen occurred in 6.7% of the participants in the semaglutide group and in 3.0% in the placebo group, with gastrointestinal disorders being the most common reason for discontinuation. Among participants with obesity and knee osteoarthritis with moderate-to-severe pain, treatment with once-weekly injectable semaglutide resulted in significantly greater reductions in body weight and pain related to knee osteoarthritis than placebo.

Liraglutide 3·0 mg was shown to reduce bodyweight and improve glucose metabolism after the 56-week period of this trial, one of four trials in the SCALE programme. In the 3-year assessment of the SCALE Obesity and Prediabetes trial we aimed to evaluate the proportion of individuals with prediabetes who were diagnosed with type 2 diabetes. In this randomised, double-blind, placebo-controlled trial, adults with prediabetes and a body-mass index of at least 30 kg/m2, or at least 27 kg/m2 with comorbidities, were randomised 2:1, using a telephone or web-based system, to once-daily subcutaneous liraglutide 3·0 mg or matched placebo, as an adjunct to a reduced-calorie diet and increased physical activity. Time to diabetes onset by 160 weeks was the primary outcome, evaluated in all randomised treated individuals with at least one post-baseline assessment. The trial was conducted at 191 clinical research sites in 27 countries and is registered with ClinicalTrials.gov, number NCT01272219. The study ran between June 1, 2011, and March 2, 2015. We randomly assigned 2254 patients to receive liraglutide (n=1505) or placebo (n=749). 1128 (50%) participants completed the study up to week 160, after withdrawal of 714 (47%) participants in the liraglutide group and 412 (55%) participants in the placebo group. By week 160, 26 (2%) of 1472 individuals in the liraglutide group versus 46 (6%) of 738 in the placebo group were diagnosed with diabetes while on treatment. The mean time from randomisation to diagnosis was 99 (SD 47) weeks for the 26 individuals in the liraglutide group versus 87 (47) weeks for the 46 individuals in the placebo group. Taking the different diagnosis frequencies between the treatment groups into account, the time to onset of diabetes over 160 weeks among all randomised individuals was 2·7 times longer with liraglutide than with placebo (95% CI 1·9 to 3·9, p<0·0001), corresponding with a hazard ratio of 0·21 (95% CI 0·13–0·34). Liraglutide induced greater weight loss than placebo at week 160 (–6·1 [SD 7·3] vs −1·9% [6·3]; estimated treatment difference −4·3%, 95% CI −4·9 to −3·7, p<0·0001). Serious adverse events were reported by 227 (15%) of 1501 randomised treated individuals in the liraglutide group versus 96 (13%) of 747 individuals in the placebo group. In this trial, we provide results for 3 years of treatment, with the limitation that withdrawn individuals were not followed up after discontinuation. Liraglutide 3·0 mg might provide health benefits in terms of reduced risk of diabetes in individuals with obesity and prediabetes. Novo Nordisk, Denmark.

Bronchiectasis guidelines are inconsistent with regard to the effectiveness of mucoactive agents, and their use varies geographically. Large trials are needed to assess safety and effectiveness. For this open-label, randomized, two-by-two factorial trial at 20 sites in the United Kingdom, we enrolled participants with non-cystic fibrosis bronchiectasis who had frequent pulmonary exacerbations and daily sputum production. Current smokers and persons who had recently received mucoactive treatments were excluded. All participants received standard care and were also assigned either to one of three mucoactive-drug groups - hypertonic saline (the hypertonic-saline group), hypertonic saline and carbocisteine (the combination group), or carbocisteine (the carbocisteine group) - or to standard care alone. The comparisons were between hypertonic saline and no hypertonic saline and between carbocisteine and no carbocisteine, with each category consisting of two groups. The primary outcome was the number of pulmonary exacerbations over a 52-week period. Key secondary outcomes were scores on disease-specific health-related quality-of-life assessments, time to next pulmonary exacerbation, and safety. A total of 288 participants underwent randomization. No treatment interactions were found. The mean number of adjudicated fully qualifying pulmonary exacerbations over the 52-week period was 0.76 (95% confidence interval [CI], 0.58 to 0.95) with hypertonic saline as compared with 0.98 (95% CI, 0.78 to 1.19) with no hypertonic saline (adjusted between-group difference in the means, -0.25 [95% CI, -0.57 to 0.07; P = 0.12]) and 0.86 (95% CI, 0.66 to 1.06) with carbocisteine as compared with 0.90 (95% CI, 0.70 to 1.09) with no carbocisteine (adjusted between-group difference in the means, -0.04 [95% CI, -0.36 to 0.28; P = 0.81]). Secondary outcomes and the incidence of adverse events, including serious adverse events, were similar across the groups. In participants with bronchiectasis, neither hypertonic saline nor carbocisteine significantly reduced the mean incidence of pulmonary exacerbations over a period of 52 weeks.

Abstract Since 2001, more than 2.7 million U.S. military personnel have been deployed in support of operations in Southwest Asia and Afghanistan. Land-based personnel experienced elevated exposures to particulate matter and other inhalational exposures from multiple sources, including desert dust, burn pit combustion, and other industrial, mobile, or military sources. A workshop conducted at the 2018 American Thoracic Society International Conference had the goals of: 1) identifying key studies assessing postdeployment respiratory health, 2) describing emerging research, and 3) highlighting knowledge gaps. The workshop reviewed epidemiologic studies that demonstrated more frequent encounters for respiratory symptoms postdeployment compared with nondeployers and for airway disease, predominantly asthma, as well as case series describing postdeployment dyspnea, asthma, and a range of other respiratory tract findings. On the basis of particulate matter effects in other populations, it also is possible that deployers experienced reductions in pulmonary function as a result of such exposure. The workshop also gave particular attention to constrictive bronchiolitis, which has been reported in lung biopsies of selected deployers. Workshop participants had heterogeneous views regarding the definition and frequency of constrictive bronchiolitis and other small airway pathologic findings in deployed populations. The workshop concluded that the relationship of airway disease, including constrictive bronchiolitis, to exposures experienced during deployment remains to be better defined. Future clinical and epidemiologic research efforts should address better characterization of deployment exposures; carry out longitudinal assessment of potentially related adverse health conditions, including lung function and other physiologic changes; and use rigorous histologic, exposure, and clinical characterization of patients with respiratory tract abnormalities.

Purpose To develop and validate a classification system for focal vitreomacular traction (VMT) with and without macular hole based on spectral domain optical coherence tomography (SD-OCT), intended to aid in decision-making and prognostication. Methods A panel of retinal specialists convened to develop this system. A literature review followed by discussion on a wide range of cases formed the basis for the proposed classification. Key features on OCT were identified and analysed for their utility in clinical practice. A final classification was devised based on two sequential, independent validation exercises to improve interobserver variability. Results This classification tool pertains to idiopathic focal VMT assessed by a horizontal line scan using SD-OCT. The system uses width (W), interface features (I), foveal shape (S), retinal pigment epithelial changes (P), elevation of vitreous attachment (E), and inner and outer retinal changes (R) to give the acronym WISPERR. Each category is scored hierarchically. Results from the second independent validation exercise indicated a high level of agreement between graders: intraclass correlation ranged from 0.84 to 0.99 for continuous variables and Fleiss’ kappa values ranged from 0.76 to 0.95 for categorical variables. Conclusions We present an OCT-based classification system for focal VMT that allows anatomical detail to be scrutinised and scored qualitatively and quantitatively using a simple, pragmatic algorithm, which may be of value in clinical practice as well as in future research studies.

Coadministration of a respiratory syncytial virus (RSV) vaccine with seasonal influenza or SARS-CoV-2 vaccines could reduce health-care visits and increase vaccination uptake in older adults who are at high risk for severe respiratory disease. The RSV mRNA-1345 vaccine demonstrated efficacy against RSV disease with acceptable safety in the ConquerRSV trial in adults aged 60 years and older. We aimed to evaluate the safety and immunogenicity of mRNA-1345 coadministered with a seasonal influenza vaccine or SARS-CoV-2 mRNA vaccine. We conducted a two-part, phase 3, observer-blinded, placebo-controlled, randomised trial in medically stable adults aged 50 years or older in the USA. In part A, participants were randomly assigned in a 7:10:10 ratio to receive 50 μg mRNA-1345 plus placebo (0·9% sodium chloride) or coadministered with 60 μg of a standard-dose quadrivalent inactivated influenza vaccine (SIIV4), or SIIV4 plus placebo. In part B, participants were randomly assigned in a 1:1:1 ratio to receive 50 μg mRNA-1345 plus placebo or coadministered with 50 μg SARS-CoV-2 mRNA-1273.214 (bivalent [Wuhan-Hu-1 plus omicron BA.1]), or mRNA-1273.214 plus placebo. Random allocation in both parts was stratified by age group (50–59 years, 60–74 years, and ≥75 years) and used interactive response technology. The coprimary objectives in each part were safety in the safety set throughout the study and non-inferiority for six immunogenicity endpoints in the per-protocol set comparing coadministered versus individual vaccines on day 29. Immunogenicity endpoints were geometric mean titre (GMT) ratios (GMRs) of RSV-A neutralising antibodies (nAbs; in parts A and B), GMRs of haemagglutination inhibition (HAI) titres to each of the four influenza strains in SIIV4 (A/Victoria/2570/2019 [H1N1]pdm09-like virus [A/H1N1], A/Cambodia/e0826360/2020 [H3N2]-like virus [A/H3N2], B/Washington/02/2019-like virus [B/Victoria], and B/Phuket/3073/2013-like virus [B/Yamagata]; in part A), GMRs of nAbs against SARS-CoV-2 (ancestral [D614G] and omicron BA.1; part B), and differences in seroresponse rates for nAbs against RSV-A (parts A and B) and SARS-CoV-2 (ancestral [D614G] and omicron BA.1; part B). Non-inferiority was declared when the lower bound of the 95% CI for GMRs was greater than 0·667 and for seroresponse rate differences was greater than −10%. This trial is registered with ClinicalTrials.gov (NCT05330975) and is ongoing. Between April 1 and June 9, 2022, 1631 participants were randomly allocated in part A and 1623 received vaccinations on day 1 (685 [42%] received mRNA-1345 plus SIIV4, 249 [15%] mRNA-1345 plus placebo, and 689 [42%] SIIV4 plus placebo). Due to an interactive response technology error, the mRNA-1345 plus placebo group was smaller than planned (249 vs 420 participants). Of the 1623 participants in the safety set, 877 (54%) were female and 746 (46%) were male. Between July 27 and Sept 28, 2022, 1691 participants were randomly allocated in part B and 1681 received vaccinations on day 1 (564 [34%] received mRNA-1345 plus mRNA-1273.214, 558 [33%] mRNA-1345 plus placebo, and 559 [33%] mRNA-1273.214 plus placebo). Among the 1681 participants in the safety set, 924 (55%) were female and 757 (45%) were male. The reactogenicity profiles of the coadministered regimens were generally similar to the profiles when the vaccines were administered alone. As of the 6-month and 7-month follow-up times for parts A and B, respectively, no serious adverse events, adverse events of special interest, discontinuations due to adverse events, or fatal events considered related to study vaccination were reported. In part A, the GMR of nAbs against RSV-A in the mRNA-1345 plus SIIV4 group versus the mRNA-1345 alone group was 0·81 (95% CI 0·67 to 0·97), and the seroresponse rate difference in nAbs against RSV-A between the groups was −11·2% (95% CI −17·9 to −4·1). GMRs of anti-HAI titres in the mRNA-1345 plus SIIV4 versus SIIV4 alone groups were 0·89 (0·77 to 1·03) for A/H1N1, 0·97 (0·86 to 1·09) for A/H3N2, 0·93 (0·82 to 1·05) for B/Victoria, and 0·91 (0·81 to 1·02) for B/Yamagata. In part B, the GMR of nAbs against RSV-A in the mRNA-1345 plus mRNA-1273.214 versus the mRNA-1345 alone groups was 0·80 (95% CI 0·70 to 0·90), and the seroresponse rate difference was –4·4% (95% CI –9·9 to 1·0). Comparing the mRNA-1345 plus mRNA-1273.214 group with the mRNA-1273.214 alone group, the GMR of nAbs was 0·96 (0·87 to 1·06) for the ancestral (D614G) virus and 1·00 (0·89 to 1·14) for omicron BA.1; seroresponse rate differences were 0·2% (95% CI –6·0 to 6·3) for SARS-CoV-2 ancestral and –0·9% (–6·6 to 4·7) for omicron BA.1. Coadministered mRNA-1345 plus SIIV4 or mRNA-1273.214 vaccines had acceptable safety profiles and elicited mostly non-inferior immune responses compared to individual vaccines in adults aged 50 years or older; only the seroresponse rate difference in nAbs against RSV-A in part A did not meet the non-inferiority criterion. Overall, these data support coadministration of mRNA-1345 with these vaccines in this population; longer-term evaluation continues in this study. Moderna.
