ABSTRACT

BACKGROUND: Immune checkpoint inhibitors (ICIs) have changed the treatment pattern of advanced and metastatic NSCLC. A series of ICI based therapies have emerged in the first-line treatment field, but the comparative efficacy was unclear.

METHOD: We searched multiple databases and abstracts of major conference proceedings up to Apri1, 2022 for phase III randomised trials of advanced driver-gene wild type NSCLC patients receiving first-line therapy. Outcomes analyzed included progression free survival (PFS), overall survival (OS), and et al.

RESULTS: Thirty-two double-blind RCTs were included, involving 18,656 patients assigned to 22 ICI-based first-line regimens. A series of ICI regiments (including ICI plus chemotherapy), ICI monotherapy, doublet ICIs, doublet ICIs plus chemotherapy) emerged, and showed significant PFS and OS benefit than chemotherapy and chemotherapy + bevacizumab (BEV) for advanced wild-type NSCLC. In comprehensive terms of PFS, chemoimmunotherapy (CIT) were significantly more effective than ICI monotherapy and doublet ICIs. In terms of OS for patients with non-squamous NSCLC, pembrolizumab containing CIT was associated with a median rank of the best regimens, and followed by Atezolizumab+BEV based CIT; while for OS in patients with squamous NSCLC, Cemiplimab and sintilimab based CIT were the most effective regimens. For more than 2 years follow-up, the atezolizumab, pembrolizumab, nivolumab and durvalumab containing ICI therapy all provide a durable long-term OS benefit over chemotherapy and BEV + chemotherapy.

CONCLUSIONS: The findings of the present NMA represent the most comprehensive evidence, which might suggest or provide basis for first-line ICI therapy decision for advanced NSCLC patients without oncogenic driver mutations.

ABSTRACT

BACKGROUND: This study explores the potential for behavioural economics techniques called ‘nudges’ to encourage the use of HIV pre-exposure prophylaxis (PrEP) by overseas-born men who have sex with men (MSM) in Australia. We investigated the preferences of overseas-born MSM for different nudges and the effect of nudges on reported likelihood of seeking information about PrEP.

METHODS: We conducted an online survey of overseas-born MSM, in which they were asked: (1) how likely they and a relevant friend would be to click on PrEP advertisements that used behavioural economics strategies; and (2) what they most and least liked about each ad. We conducted ordered logistic regression of reported likelihood scores against participant age and sexual orientation, use of a model in an advertisement, use of statistics about PrEP, reference to the World Health Organization (WHO), rewards for seeking further information, and use of a call-to-action.

RESULTS: Participants (n =324) reported higher likelihoods of clicking on advertisements with images of people, statistics about PrEP, rewards for seeking further information, and calls-to-action. They reported lower likelihoods of clicking on advertisements referencing the WHO. They had negative emotional responses to sexualised humour, gambling metaphors, and the slogan ‘Live Fearlessly’.

CONCLUSIONS: Overseas-born MSM prefer public health messages that feature representative messengers and statistics about PrEP. These preferences are consistent with previous data on descriptive norms (i.e. statistics about the number of peers doing the desired behaviour) and gain-framed information (i.e. focusing on what can be gained from an intervention).

ABSTRACT

BACKGROUND: Multiple sclerosis (MS), one of the main neurological causes of disability seen at young ages, affects the quality of life of patients. Studies on which dietary pattern or consumption of food groups may have an impact on quality of life for MS patients are insufficient. The study was conducted to determine the relationship between adherence to Mediterranean diet and consumption levels of food groups on quality of life in multiple sclerosis patients.

METHODS: This study was conducted with 95 patients, 76 females and 19 males, aged 18-65 years, who had been diagnosed with MS for at least 2 years and did not have any other chronic disease. Food Frequency Questionnaire, Mediterranean Diet Adherence Screener (MEDAS), Expanded Disability Status Scale (EDSS) and Multiple Sclerosis Quality of Life-54 Instrument (MS-QoL-54) used as tools. Data were analyzed by SPSS 25.0.

RESULTS: Adherence to the Mediterranean diet was associated with EDSS and physical and mental quality of life parameters (CPH and CMH), independent of progression. It was associated with EDSS and CMH in progressive MS. A statistically significant negative weak correlation was found between daily milk and oilseed consumption and EDSS. Daily fruit consumption was associated with CMH, and vegetable consumption was associated with both CPH and CMH.

CONCLUSIONS: The Mediterranean diet may be an effective nutritional model in MS patients and may be related to the disability level and quality of life of the patients. Some food groups can be associated with the quality of life and disability level of MS patients.

ABSTRACT

Considering the time delay originating from a certain incubation period or asymptomatic state, we propose a delayed epidemic system within the noisy environment of the hepatitis B virus to analyze the mechanism of disease transmission and elucidate how to control it by applying the strategy of vaccinating and treatment. Applying stochastic Lyapunov functional theory, we first construct an integral Lyapunov function coupling the time delay and stochastic fluctuation to investigate whether there exists a unique global solution to the model. Next, we yield the threshold condition for controlling disease extinction, and persistence, as well as its stationary distribution. Governed by these sufficient conditions, we study the existence of optimal control solutions in deterministic and stochastic scenarios to uncover how to accelerate disease extinction through vaccination and treatment. The results indicate that the time delay will prolong the duration of the disease for the original system but suppress the peak value of HBV in the controlled system. Finally, we verify the versatility of theoretical results by numerical simulations. These results will effectively decipher the importance of the time delay in the control of hepatitis B.

ABSTRACT

Night-Time Scene Parsing (NTSP) is essential to many vision applications, especially for autonomous driving. Most of the existing methods are proposed for day-time scene parsing. They rely on modeling pixel intensity-based spatial contextual cues under even illumination. Hence, these methods do not perform well in night-time scenes as such spatial contextual cues are buried in the over-/under-exposed regions in night-time scenes. In this paper, we first conduct an image frequency-based statistical experiment to interpret the day-time and night-time scene discrepancies. We find that image frequency distributions differ significantly between day-time and night-time scenes, and understanding such frequency distributions is critical to NTSP problem. Based on this, we propose to exploit the image frequency distributions for night-time scene parsing. First, we propose a Learnable Frequency Encoder (LFE) to model the relationship between different frequency coefficients to measure all frequency components dynamically. Second, we propose a Spatial Frequency Fusion module (SFF) that fuses both spatial and frequency information to guide the extraction of spatial context features. Extensive experiments show that our method performs favorably against the state-of-the-art methods on the NightCity, NightCity+ and BDD100K-night datasets. In addition, we demonstrate that our method can be applied to existing day-time scene parsing methods and boost their performance on night-time scenes.

ABSTRACT

BACKGROUND: Computed tomography (CT) and magnetic resonance imaging (MRI) are indicated for use in preoperative planning and may complicate diagnosis and place a burden on patients with lumbar disc herniation.

PURPOSE: To investigate the diagnostic potential of MRI-based synthetic CT with conventional CT in the diagnosis of lumbar disc herniation.

MATERIAL AND METHODS: After obtaining prior institutional review board approval, 19 patients who underwent conventional and synthetic CT imaging were enrolled in this prospective study. Synthetic CT images were generated from the MRI data using U-net. The two sets of images were compared and analyzed qualitatively by two musculoskeletal radiologists. The images were rated on a 4-point scale to determine their subjective quality. The agreement between the conventional and synthetic images for a diagnosis of lumbar disc herniation was determined independently using the kappa statistic. The diagnostic performances of conventional and synthetic CT images were evaluated for sensitivity, specificity, and accuracy, and the consensual results based on T2-weighted imaging were employed as the reference standard.

RESULTS: The inter-reader and intra-reader agreement were almost moderate for all evaluated modalities (κ = 0.57-0.79 and 0.47-0.75, respectively). The sensitivity, specificity, and accuracy for detecting lumbar disc herniation were similar for synthetic and conventional CT images (synthetic vs. conventional, reader 1: sensitivity = 91% vs. 81%, specificity = 83% vs. 100%, accuracy = 87% vs. 91%; P < 0.001; reader 2: sensitivity = 84% vs. 81%, specificity = 85% vs. 98%, accuracy = 84% vs. 90%; P < 0.001).

CONCLUSION: Synthetic CT images can be used in the diagnostics of lumbar disc herniation.

ABSTRACT

OBJECTIVE: To evaluate the impact of sacubitril/valsartan on blood pressure (BP), ventricular structure, and myocardial fibrosis compared with valsartan in perimenopausal hypertensive women.

METHODS: This prospective, randomized, actively controlled, open-label study included 292 women with perimenopausal hypertension. They were randomly divided into two groups: sacubitril/valsartan 200 mg once daily and valsartan 160 mg once daily for 24 weeks. The relevant indicators of ambulatory BP, echocardiography, and myocardial fibrosis regulation were assessed at baseline and at 24 weeks.

RESULTS: The 24-h mean SBP after 24 weeks of treatment was 120.08 ± 10.47 mmHg in the sacubitril/valsartan group versus 121.00 ± 9.76 mmHg in the valsartan group (P = 0.457). After 24 weeks of treatment, there was no difference in central SBP between the sacubitril/valsartan and valsartan groups (117.17 ± 11.63 versus 116.38 ± 11.58, P = 0.568). LVMI in the sacubitril/valsartan group was lower than that in the valsartan group at week 24 (P = 0.009). LVMI decreased by 7.23 g/m2 from the baseline in the sacubitril/valsartan group and 3.70 g/m2 in the valsartan group at 24 weeks (P = 0.000 versus 0.017). A statistically significant difference in LVMI between the two groups was observed at 24 weeks after adjusting for the baseline LVMI (P = 0.001). The levels of α-smooth muscle actin (α-SMA), connective tissue growth factor (CT-GF) and transforming growth factor-β (TGF-β) were reduced in the sacubitril/valsartan group compared with the baseline (P = 0.000, 0.005, and 0.000). LVMI between the two groups was statistically significant at 24 weeks after correcting for confounding factors 24-h mean SBP and 24-h mean DBP (P = 0.005). The LVMI, serum TGF-β, α-SMA, and CT-GF remained statistically significant between the two groups after further correcting the factors of age, BMI, and sex hormone levels (P < 0.05).

CONCLUSION: Sacubitril/valsartan could reverse ventricular remodeling more effectively than valsartan. The different effects of these two therapies on ventricular remodeling in perimenopausal hypertensive women might be because of their different effects on the down-regulation of fibrosis-related factors.

ABSTRACT

IMPORTANCE: Patients attending US abortion clinics may consider or try self-managing their abortion before coming to the clinic, yet little is known about the factors associated with self-management behavior.

OBJECTIVE: To examine the prevalence and factors associated with considering or attempting a self-managed abortion before attending a clinic.

DESIGN, SETTING, AND PARTICIPANTS: This survey study included patients obtaining an abortion at 49 independent, Planned Parenthood, and academic-affiliated clinics chosen to maximize diversity in geographic, state policy, and demographic context in 29 states between December 2018 and May 2020. Data were analyzed from December 2020 to July 2021.

EXPOSURES: Obtaining an abortion at a clinic.

MAIN OUTCOMES AND MEASURES: Knowledge of medications used to self-manage an abortion, having considered medication self-management before attending the clinic, having considered any method of self-management before attending the clinic, and having tried any method of self-management before attending the clinic.

RESULTS: The study included 19 830 patients, of which 99.6.% (17 823 patients) identified as female; 60.9% (11 834 patients) were aged 20 to 29 years; 29.6% (5824 patients) identified as Black, 19.3% (3799 patients) as Hispanic, and 36.0% (7095 patients) as non-Hispanic White; 44.1% (8252 patients) received social services; and 78.3% (15 197 patients) were 10 weeks pregnant or less. Approximately 1 in 3 (34%) knew about self-managed medication abortion, and among this subsample of 6750 patients, 1 in 6 (1079 patients [16.1%]) had considered using medications to self-manage before attending the clinic. Among the full sample, 1 in 8 (11.7%) considered self-managing using any method before clinic attendance, and among this subsample of 2328 patients, almost 1 in 3 (670 patients [28.8%]) attempted to do so. Preference for at-home abortion care was associated with considering medication self-management (odds ratio [OR], 3.52; 95% CI, 2.94-4.21), considering any method of self-management (OR, 2.80; 95% CI, 2.50-3.13), and attempting any method of self-management (OR, 1.37; 95% CI, 1.10-1.69). Experiencing clinic access barriers was also associated with considering medication self-management (OR, 1.98; 95% CI, 1.69-2.32) and considering any method of self-management (OR, 2.09; 95% CI, 1.89-2.32).

CONCLUSIONS AND RELEVANCE: In this survey study, considering self-managed abortion was common before accessing in-clinic care, particularly among those on the margins of access or with a preference for at-home care. These findings suggest a need for expanded access to telemedicine and other decentralized abortion care models.

ABSTRACT

IMPORTANCE: Recent information on the prevalence of prescription stimulant therapy for attention-deficit/hyperactivity disorder (ADHD) and nonmedical use of prescription stimulants (NUPS) at the school-level among US secondary school students is limited.

OBJECTIVE: To investigate the school-level prevalence of and association between stimulant therapy for ADHD and NUPS among US secondary school students.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used survey data collected between 2005 and 2020 as part of the Monitoring the Future study (data collected annually via self-administered survey in schools from independent cohorts). Participants were from a nationally representative sample of 3284 US secondary schools. The mean (SD) response rates were 89.5% (1.3%) for 8th-grade students, 87.4% (1.1%) for 10th-grade students, and 81.5% (1.8%) for 12th-grade students. Statistical analysis was performed from July to September 2022.

MAIN OUTCOME AND MEASURE: Past-year NUPS.

RESULTS: The 3284 schools contained 231 141 US 8th-, 10th-, and 12th-grade students (111 864 [50.8%, weighted] female; 27 234 [11.8%, weighted] Black, 37 400 [16.2%, weighted] Hispanic, 122 661 [53.1%, weighted] White, 43 846 [19.0%, weighted] other race and ethnicity). Across US secondary schools, the past-year prevalence of NUPS ranged from 0% to more than 25%. The adjusted odds of an individual engaging in past-year NUPS were higher at secondary schools with higher proportions of students who reported stimulant therapy for ADHD, after controlling for other individual-level and school-level covariates. Students attending schools with the highest rates of prescription stimulant therapy for ADHD had approximately 36% increased odds of past-year NUPS compared with students attending schools with no medical use of prescription stimulants (adjusted odds ratio, 1.36; 95% CI, 1.20-1.55). Other significant school-level risk factors included schools in more recent cohorts (2015-2020), schools with higher proportions of parents with higher levels of education, schools located in non-Northeastern regions, schools located in suburban areas, schools with higher proportion of White students, and schools with medium levels of binge drinking.

CONCLUSIONS AND RELEVANCE: In this cross-sectional study of US secondary schools, the prevalence of past-year NUPS varied widely, highlighting the need for schools to assess their own students rather than relying solely on regional, state, or national results. The study offered new evidence of an association between a greater proportion of the student body that uses stimulant therapy and a greater risk for NUPS in schools. The association between greater school-level stimulant therapy for ADHD and other school-level risk factors suggests valuable targets for monitoring, risk-reduction strategies, and preventive efforts to reduce NUPS.

ABSTRACT

Background: In Poland, Lyme borreliosis (LB) has been subject to mandatory public health surveillance since 1996 and, in accordance with EU regulations, Lyme neuroborreliosis has been reported to the European Centre for Disease Prevention and Control since 2019. In this study, the incidence, temporal trends, and geographic distribution of LB and its manifestations in Poland are described for the period 2015-2019. Methods: This retrospective incidence study of LB and its manifestations in Poland was based on data sent to the National Institute of Public Health-National Institute of Hygiene-National Research Institute (NIPH-NIH-NRI) by district sanitary epidemiological stations using the electronic Epidemiological Records Registration System and data from the National Database on Hospitalization. Incidence rates were calculated using population data from the Central Statistical Office. Results: During 2015-2019, Poland reported 94,715 cases of LB with an overall average incidence of 49.3 cases per 100,000 population. Cases increased from 2015 (11,945) to 2016 (20,857) and then remained stable through 2019. Hospitalization due to LB also rose during these years. LB was more common among women (55.7%). Erythema migrans and Lyme arthritis were the most common manifestations of LB. The highest incidence rates occurred among >50-year-olds, with a peak in 65-69-year-olds. The highest number of cases was recorded in the third and fourth quarters of the year (July-December). Incidence rates in the eastern and northeastern regions of the country were higher than the national average. Conclusions: LB is endemic in all regions of Poland, and many regions reported high incidence rates. Large variations in spatially granular incidence rates highlight the need for targeted prevention strategies.
