Lung transplant (LTx) evaluation and selection of candidates with connective tissue disease (CTD) remains controversial and varies between centers, and the optimal candidate selection is still controversial.

Recent United States and European publications have reported reasonable short-term and long-term LTx outcomes in patients with CTD to other lung fibrosis patients without CTD. This article discusses the recently published International Society for Heart and Lung Transplantation (ISHLT) consensus document recommendations to evaluate and select CTD candidates, the importance of early referral, posttransplant management, and the involvement of a multidisciplinary team.

Future standardized practices among centers adapting the 2021 ISHLT consensus recommendations to evaluate and select CTD candidates will allow risk stratification, determine the best candidates, and facilitate the most successful long-term LTx outcomes.

Recent evidence indicates that plasma donor-derived cell-free DNA (dd-cfDNA) is a sensitive biomarker for the detection of underlying allograft injury, including rejection and infection. In this review, we will cover the latest evidence revolving around dd-cfDNA in lung transplantation and its role in both advancing mechanistic insight into disease states in lung transplant recipients as well as its potential clinical utility.

Plasma dd-cfDNA increases in the setting of allograft injury, including in primary graft dysfunction, acute cellular rejection, antibody-mediated rejection and infection. Dd-cfDNA has demonstrated good performance characteristics for the detection of various allograft injury states, most notably with a high negative-predictive value for detection of acute rejection. Elevated levels of dd-cfDNA in the early posttransplant period, reflecting molecular evidence of lung allograft injury, are associated with increased risk of chronic lung allograft dysfunction and death.

As a quantitative, molecular biomarker of lung allograft injury, dd-cfDNA holds great promise in clinical and research settings for advancing methods of posttransplant surveillance monitoring, diagnosis of allograft injury states, monitoring adequacy of immunosuppression, risk stratification and unlocking pathophysiological mechanisms of various disease.

Despite improvements in available medical therapies, pulmonary arterial hypertension (PAH) remains a progressive, ultimately fatal disorder. Lung transplantation is a viable treatment option for PAH patients with advanced disease.

Recent guidelines from the International Society of Heart and Lung Transplantation (ISHLT) have updated recommendations regarding time of referral and listing for lung transplantation in PAH. The new guidelines emphasize earlier referral for transplant evaluation to ensure adequate time for proper evaluation and listing. They also incorporate objective risk stratification criteria to assist in decision-making regarding timing of referral and listing. With regards to the transplant procedure, bilateral lung transplantation has largely supplanted heart-lung transplantation as the procedure of choice for transplantation for advanced PAH. Exceptions to this include patients with PAH because of congenital heart disease and those with concurrent LV dysfunction. Use of mechanical suppo support.
Electroretinography (ERG) is used prior to cataract removal surgery to assess retinal function. We aimed to replicate and improve upon previous studies by performing a full ECVO protocol and by examining the retina post-surgery in all patients.

One hundred twenty-seven eyes from 67 dogs were included in the study.

A full ECVO protocol electroretinography, which includes extensive rod and cone analysis, was performed on all dogs presenting for cataract surgery.

Our main findings were that amplitudes, but not implicit times of rod responses decreased with advanced cataracts. Amplitudes of the single flash rod and rod flicker responses were significantly lower in eyes with mature cataracts, and the former also decreased in hypermature cataracts. Cone flicker amplitude responses were also significantly lower in eyes with mature and hypermature cataracts. However, mixed single flash rod-cone and cone responses, with the exception of the mixed rod-cone a-wave amplitude in eyes with hypermature cataracts, were unaffected by cataract stage. The b-wave amplitude of the scotopic, mixed rod-cone, and photopic cone responses were affected by age and decreased by an average of 2.9, 7.5, and 1.5μV/year, retrospectively (p < 0.01).

Lower ERG amplitudes in canine cataract patients may result from aging or the presence of advanced cataracts and may not indicate the presence of retinal disease.

Anatomical changes occurred during the treatment course of radiation therapy for lung cancer patients may introduce clinically unacceptable dosimetric deviations from the planned dose. Adaptive radiotherapy (ART) can compensate these dosimetric deviations in subsequent treatments via plan adaption. Determining whether and when to trigger plan adaption during the treatment course is essential to the effectiveness and efficiency of ART. In this study, we aimed to develop a prediction model as an auxiliary decision-making tool for lung ART to identify the patients with intrathoracic anatomical changes that would potentially benefit from the plan adaptions during the treatment course.

Seventy-one pairs of weekly cone-beam computer tomography (CBCT) and planning CT (pCT) from 17 advanced non-small cell lung cancer patients were enrolled in this study. To assess the dosimetric impacts brought by anatomical changes observed on each CBCT, dose distribution of the original treatment plan on the CBCT anatomy was cae anatomical changes with the dosimetric impacts for lung ART. This model can be a promising tool to assist the clinicians in making decisions for plan adaptions during the treatment courses.
We built a prediction model based on the features of patient anatomy and the anatomical changes captured by on-treatment CBCT imaging to trigger plan adaption for lung cancer patients. This model effectively associated the anatomical changes with the dosimetric impacts for lung ART. This model can be a promising tool to assist the clinicians in making decisions for plan adaptions during the treatment courses.
The heterogeneous nature of chronic obstructive pulmonary disease (COPD) complicates the identification of the predictors of disease progression. We aimed to improve the prediction of disease progression in COPD by using machine learning and incorporating a rich dataset of phenotypic features.

We included 4496 smokers with available data from their enrollment and 5-year follow-up visits in the COPD Genetic Epidemiology (COPDGene
) study. We constructed linear regression (LR) and supervised random forest models to predict 5-year progression in forced expiratory in 1 second (FEV
) from 46 baseline features. Using cross-validation, we randomly partitioned participants into training and testing samples. We also validated the results in the COPDGene 10-year follow-up visit.

Predicting the change in FEV
over time is more challenging than simply predicting the future absolute FEV
level. For random forest, R-squared was 0.15 and the area under the receiver operator characteristic (ROC) curves for the predction model facilitates the identification of smokers at increased risk for rapid disease progression. Such findings may be useful in the selection of patient populations for targeted clinical trials.This study analyzed the views of physicians towards coordination of clinical management between different levels of care. This was a cross-sectional quantitative study using data from a survey of 182 physicians in primary healthcare (PHC) and specialized care in Recife, Pernambuco State, Brazil, in 2017. The results revealed significant differences in the physicians' experience. Considering referrals, the majority (81.32%) felt that PHC physicians referred patients to specialized care when necessary, and the proportion was higher in PHC physicians themselves (92.73%). As for agreement, two-thirds of PHC physicians (67.27%) reported that they agreed with the treatment prescribed by the specialist, while only 33.86% of the specialists agreed with the PHC physician. Concerning clinical responsibility, 89.09% of PHC physicians reported that they were clinically responsible for the patient, compared to only 43.31% of the specialists. As for recommendations, most of the interviewees (63.19%) felt that the specialists did not issue recommendations, and this proportion was higher among PHC physicians (81.82%). For waiting time, the majority (82.42%) felt that patients waited too long for appointments in specialized care, and the proportion was higher among PHC physicians (98.18%) than among specialists (75.59%). Only 16.36% of PHC physicians felt that waiting time was too long in PHC, compared to 38.58% of the medical specialists.

Through the metaphor of the seven capital sins, the article analyzes the phenomenon of fake news in the social media and in the scenario of the COVID-19 pandemic the lust of sensationalism through the seduction and exploitation of vulnerabilities associated with fear of death; gluttony for confirmatory contents that spread untruths in the attempt to turn versions into facts; the catechism of denialism, fueling wrath or hate in restrictive epistemic environments; the greed of new technologies in the attention economy through engagement as a new commodity; competition for the spotlights of media visibility and derived gains that incite pride and envy in researchers that confuse public meaning with fake research, in a cycle that feeds sensationalism, gluttony, hate, and greed in attention capitalism. Finally, sloth is portrayed as the capital sin of opting for communicative inaction.
