    Abstract Phrenic nerve injury results in paralysis of the diaphragm muscle, the primary generator of an inspiratory effort, as well as a stabilizing muscle involved in postural control and spinal alignment. Unilateral deficits often result in exertional dyspnea, orthopnea, and sleep-disordered breathing, whereas oxygen or ventilator dependency can occur with bilateral paralysis. Common etiologies of phrenic injuries include cervical trauma, iatrogenic injury in the neck or chest, and neuralgic amyotrophy. Many patients have no identifiable etiology and are considered to have idiopathic paralysis. Diagnostic evaluation requires radiographic and pulmonary function testing, as well as electrodiagnostic assessment to quantitate the nerve deficit and determine the extent of denervation atrophy. Treatment for symptomatic diaphragm paralysis has traditionally been limited. Medical therapies and nocturnal positive airway pressure may provide some benefit. Surgical repair of the nerve injury to restore functional diaphragmatic activity, termed phrenic nerve reconstruction, is a safe and effective alternative to static repositioning of the diaphragm (diaphragm plication), in properly selected patients. Phrenic nerve reconstruction has increasingly become a standard surgical treatment for diaphragm paralysis due to phrenic nerve injury. A multidisciplinary approach at specialty referral centers combining diagnostic evaluation, surgical treatment, and rehabilitation is required to achieve optimal long-term outcomes.

    Abstract Background: Earlier antiretroviral therapy (ART) may decrease progression to advanced HIV disease (AHD) with CD4 count of <200 cells per cubic millimeter or clinical sequelae. We assessed factors associated with AHD among people living with HIV before and during the "test and treat" era.
    Setting: The African Cohort Study prospectively enrolls adults with and without HIV from 12 clinics in Uganda, Kenya, Tanzania, and Nigeria.
    Methods: Enrollment evaluations included clinical history, physical examination, and laboratory testing. Generalized estimating equations were used to estimate adjusted odds ratios and 95% confidence intervals for factors associated with CD4 count of <200 cells per cubic millimeter at study visits.
    Results: From 2013 to 2021, 3059 people living with HIV with available CD4 at enrollment were included; median age was 38 years [interquartile range: 30-46 years], and 41.3% were men. From 2013 to 2021, the prevalence of CD4 count of <200 cells per cubic millimeter decreased from 10.5% to 3.1%, whereas the percentage on ART increased from 76.6% to 100% ( P <0.001). Factors associated with higher odds of CD4 count of <200 cells per cubic millimeter were male sex (adjusted odds ratio 1.56 [confidence interval: 1.29 to 1.89]), being 30-39 years (1.42 [1.11-1.82]) or older (compared with <30), have World Health Organization stage 2 disease (1.91 [1.48-2.49]) or higher (compared with stage 1), and HIV diagnosis eras 2013-2015 (2.19 [1.42-3.37]) or later (compared with <2006). Compared with ART-naive, unsuppressed participants, being viral load suppressed on ART, regardless of ART duration, was associated with lower odds of CD4 count of <200 cells per cubic millimeter (<6 months on ART: 0.45 [0.34-0.58]).
    Conclusion: With ART scale-up, AHD has declined. Efforts targeting timely initiation of suppressive ART may further reduce AHD risk.

    Abstract The sequencing of SARS-CoV-2 RNA in wastewater is an unbiased method to detect the spread of emerging variants and to track regional infection dynamics, which is especially useful in case of limited testing and clinical sequencing. To test how major international events influence the spread of new variants we have sequenced SARS-CoV-2 RNA in the wastewater samples of Davos, Landquart, Lostallo, and St. Moritz in the Swiss canton of Grisons in the time around the international sports competitions in Davos and St. Moritz in December 2021, and additionally in May 2022 and January 2023 in Davos and St. Moritz during the World Economic Forum (WEF) in Davos. The prevalence of the variants identified from the wastewater sequencing data showed that the Omicron variant BA.1 had spread in Davos and St. Moritz during the international sporting events hosted there in December 2021. This spread was associated with an increase in case numbers, while it was not observed in Landquart and Lostallo. Another instance of new variant spread occurred during the WEF in January 2023, when the Omicron variant BA.2.75 arrived in Davos but not in St. Moritz. We can therefore conclude that major international events promote the spread of new variants in the respective host region, which has important implications for the protective measures that should be taken.

    Abstract In quasi-Monte Carlo methods, generating high-dimensional low discrepancy sequences by generator matrices is a popular and efficient approach. Historically, constructing or finding such generator matrices has been a hard problem. In particular, it is challenging to take advantage of the intrinsic structure of a given numerical problem to design samplers of low discrepancy in certain subsets of dimensions. To address this issue, we devise a greedy algorithm allowing us to translate desired net properties into linear constraints on the generator matrix entries. Solving the resulting integer linear program yields generator matrices that satisfy the desired net properties. We demonstrate that our method finds generator matrices in challenging settings, offering low discrepancy sequences beyond the limitations of classic constructions.

    Abstract Much effort has been put into developing samplers with specific properties, such as producing blue noise, low-discrepancy, lattice or Poisson disk samples. These samplers can be slow if they rely on optimization processes, may rely on a wide range of numerical methods, are not always differentiable. The success of recent diffusion models for image generation suggests that these models could be appropriate for learning how to generate point sets from examples. However, their convolutional nature makes these methods impractical for dealing with scattered data such as point sets. We propose a generic way to produce 2-d point sets imitating existing samplers from observed point sets using a diffusion model. We address the problem of convolutional layers by leveraging neighborhood information from an optimal transport matching to a uniform grid, that allows us to benefit from fast convolutions on grids, and to support the example-based learning of non-uniform sampling patterns. We demonstrate how the differentiability of our approach can be used to optimize point sets to enforce properties.

    Abstract Background: Heart failure following myocardial infarction (MI) remains one of the major causes of death worldwide, and its treatment is a crucial challenge of cardiovascular medicine. An attractive therapeutic strategy is to stimulate endogenous mechanisms of myocardial regeneration.
    Objectives: This study evaluates the potential therapeutic treatment with annexin A1 (AnxA1) to induce cardiac repair after MI.
    Methods: AnxA1 knockout (AnxA1
    Results: AnxA1
    Conclusions: AnxA1 has a direct action on cardiac macrophage polarization toward a pro-angiogenic, reparative phenotype. AnxA1 stimulated cardiac macrophages to release high amounts of VEGF-A, thus inducing neovascularization and cardiac repair.
