With rising interest in lowering energy costs for low- and moderate-income households, the U.S. Department of Energy (DOE) asked Lawrence Berkeley National Laboratory (LBNL) to assess the implications of pursuing energy efficiency neighborhood-by-neighborhood where those households are most prevalent. DOE provided certain scenarios for qualifying geographic areas as “low- and moderate-income communities,” and LBNL used data on demographics, housing types and recent savings from low-income retrofits or weatherization to provide rough electricity savings estimates under those scenarios.

Nanoparticle albumin-bound (nab)-paclitaxel is paclitaxel linked to albumin nanoparticles, which makes it soluble and is an example of an application of nanotechnology for cancer treatment. The development of nanotechnology as a delivery system for nab-paclitaxel has improved the pharmacokinetics and pharmacodynamics of paclitaxel, in part by decreasing its hydrophobicity. Nab-paclitaxel in combination with gemcitabine has slightly improved survival in pancreatic cancer, compared to gemcitabine alone, as demonstrated in Phase III clinical trials. Cell cycle phase-specific drugs, such as nab-paclitaxel, which target cells in the G2/M phase of the cell cycle, can only have limited efficacy since the vast majority of cells in a tumor are quiescent in G0/G1 phase. Recent advances in our laboratory on how to decoy cancer cells to cycle and then trap them in a sensitive phase of the cell cycle, can, in the hopefully near future, allow drugs such as nab-paclitaxel to have high efficacy, even in a treatment-resistant tumor such as pancreatic cancer.

The NLRP3 inflammasome is an intracellular complex that regulates the release of proinflammatory cytokines such as interleukin-1β in response to exogenous pathogens and endogenous danger signals. Evidence from studies involving human genetics, human ex vivo mononuclear cell responses, and in vivo and in vitro murine models confirms the importance of the inflammasome and interleukin-1β in the pathogenesis of several inherited and complex diseases. The availability of several effective interleukin-1β targeted therapies has allowed for successful proof-of-concept studies in several of these disorders. However, many other diseases are likely to be mediated by the inflammasome and interleukin-1β, providing additional targets in the future.

Autoinflammatory diseases are monogenic and polygenic disorders due to dysregulation of the innate immune system. The inherited conditions have been clustered with primary immunodeficiencies in the latest practice parameters; however, these diseases have unique clinical presentations, genetics, and available therapies. Given the presentation of fevers, rashes, and mucosal symptoms observed in many of these syndromes, patients are likely to present to an allergist/immunologist. Although there has been attention in the literature to diagnosis and treatment of rare, genetically defined autoinflammatory disorders, physicians are challenged by increasing numbers of patients with intermittent or periodic fevers who face unnecessary morbidities due to a lack of a diagnosis. The broad differential of diseases presenting with fever includes autoinflammatory syndromes, infections associated with immunodeficiency and/or allergies complicated by infection, and less commonly, autoimmune disorders or malignancy. To address this challenge, we review the history of the medical approach to fever, current diagnostic paradigms, and controversies in management. We describe the spectrum of disorders referred to a recurrent fever disorders clinic established in an Allergy/Immunology division at a tertiary pediatric care center. Finally, we provide practical recommendations including historical features and initial laboratory investigations that can help clinicians appropriately manage these patients.

In order to understand HIV-positive Malawian adults' experiences with hypertension management, we conducted qualitative interviews with 30 hypertensive adults who were also taking antiretroviral therapy. These interviews regarding hypertension management behaviours and beliefs were audio-recorded, transcribed, translated into English, and coded in Atlas.ti. Despite acknowledging the dangers of hypertension and the benefits of medication, many respondents missed their antihypertensive medication. Primary reasons included feeling healthy, health workers' advice to stop taking medicine when blood pressure normalised, side effects, and using herbs or non-prescription medicines to manage hypertension. Women highlighted difficulties with dietary modifications, and changes in their social relationships. Both men and women spoke about hypertension-related challenges with employment and household economics. These results suggest numerous challenges among adults managing hypertension and HIV in Malawi, and frequent suboptimal adherence to medication. We identified new key themes - the quality of adherence counselling for antihypertensive medication, the effects of hypertension on financial stability, and the role of social relationships in self-care - and encourage further investigation into these topics in low-income, high-burden countries.
