    Abstract Purpose of review: The aim of this review is to summarize the clinical outcomes of people living with HIV (PWH) coinfected with SARS-CoV-2 during the first six months of the COVID-19 pandemic.
    Recent findings: Several reports from single centers have described increased, decreased, or no difference in outcomes of COVID-19 in PWH. These studies have come from a range of locations, each with different underlying HIV prevalence and access to various antiretroviral therapy (ART) regimens. Differences in healthcare quality, access and policies may also affect reported outcomes in PWH across different locations, making interpretation of results more challenging. Meanwhile, different components of ART have been proposed to protect against SARS-CoV-2 acquisition or disease progression.
    Summary: The current review considers 6 months of data across geographic regions with a range of healthcare quality and access and ART regimens to generate a wider view of COVID-19 outcomes in PWH. Taken together, these studies indicate that HIV infection may be associated with increased risk of COVID-19 diagnosis, but comorbidities appear to play a larger role than HIV-specific variables in outcomes of COVID-19 among PWH. ART does not appear to protect from COVID-19 disease acquisition, progression or death.

  3. Article: Brain-wide arousal signals are segregated from movement planning in the superior colliculus.

    Abstract The superior colliculus (SC) is traditionally considered a brain region that functions as an interface between processing visual inputs and generating eye movement outputs. Although its role as a primary reflex center is thought to be conserved across vertebrate species, evidence suggests that the SC has evolved to support higher-order cognitive functions including spatial attention. When it comes to oculomotor areas such as the SC, it is critical that high precision fixation and eye movements are maintained even in the presence of signals related to ongoing changes in cognition and brain state, both of which have the potential to interfere with eye position encoding and movement generation. In this study, we recorded spiking responses of neuronal populations in the SC while monkeys performed a memory-guided saccade task and found that the activity of some of the neurons fluctuated over tens of minutes. By leveraging the statistical power afforded by high-dimensional neuronal recordings, we were able to identify a low-dimensional pattern of activity that was correlated with the subjects' arousal levels. Importantly, we found that the spiking responses of deep-layer SC neurons were less correlated with this brain-wide arousal signal, and that neural activity associated with changes in pupil size and saccade tuning did not overlap in population activity space with movement initiation signals. Taken together, these findings provide a framework for understanding how signals related to cognition and arousal can be embedded in the population activity of oculomotor structures without compromising the fidelity of the motor output.

    Abstract Cell and gene therapy (CGT) has a variety of potential applications in HIV prevention and management. Bibliometric and network analyses suggest potential points of entry for gene therapists into HIV cure research. The existing network of CGT researchers for HIV cure will benefit from an influx of fresh ideas and energy from CGT researchers keen to embrace a new challenge for an old virus.

    Abstract In Ojha, H.; Schofield, N.; Camkin, J. (Eds.). Climate risks to water security: framing effective response in Asia and the Pacific. Cham, Switzerland: Palgrave Macmillan

    The Central Dry Zone (CDZ) of Myanmar is the heartland of the Burmese culture, and in many ways, it is socially and culturally coherent with the other rice-centred cultures of mainland Southeast Asia. In climatic terms, it is a semi-arid outlier in a mostly wet-tropical region. Climate change is exacerbating weather variability and water insecurity, and the CDZ thus epitomises the challenges posed by climate change for much of the region. This chapter describes two examples of interventions aimed at addressing water insecurity in the CDZ: pumped irrigation at Pyawt Ywar; and artesian groundwater in the Pale Subbasin. Both address the interconnections between social and physical drivers of vulnerability. They demonstrate the challenges and importance of working across institutional scales. These examples demonstrate that progress is possible at local levels despite a lack of (or inappropriate) national policy and regulations, which limit the scale, and possibly the long-term sustainability of such gains.
