Older adults undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) experience significant challenges while navigating their homes after surgery and are at higher risk for falls and injuries. This study explored the specific home and community physical environment challenges faced by community-dwelling older adults while performing daily activities and actions taken to modify their homes before surgery. Using a qualitative descriptive methodology, semistructured interviews were conducted with 22 older adult-care partner dyads pre- and postsurgery to identify key built environment barriers and facilitators in addition to home modifications made pre- and postsurgery. Challenges anticipated by participants to perform daily activities presurgery varied from those experienced postsurgery. Lack of support along stairs or in bathrooms, flooring material, and transitions were significant concerns raised by the participants before surgery. Size and layout of home and ergonomics of resting furniture were recognized as issues postsurgery. Modifications ranged from easy fixes such as rearranging furniture, removing clutter, and installing grab bars to high-cost structural changes such as remodeling critical spaces such as bathrooms. Although participants agreed on the importance of conducting proactive home assessments and modifications before surgery, perceived costs and lack of knowledge or services limit older adults from implementing some changes. Home modifications must be considered proactively before an event such as a THA or TKA. These should be done within the context of the specific needs, abilities, financial capabilities, and social and physical home environments of the individual and the residential caregivers.

Cartilage and bone damage in RA are associated with elevated IL-1β. https://www.selleckchem.com/products/triptolide.html The effects of IL-1β can be reduced by biological therapies that target IL-1β or TNF-α. However, the mechanisms responsible for increased IL-1β and the effect of anti-TNF-α have not been fully elucidated. Recently, sterile-α and armadillo motif containing protein (SARM) was identified as a negative regulator of toll-like receptor (TLR) induced IL-1β secretion through an interaction with the inflammasome. This study set out to investigate SARM during TLR-induced IL-1β secretion in RA peripheral blood monocytes and in patients commencing anti-TNF-α treatment. Monocytes were isolated from RA patients and healthy controls; disease activity was measured by DAS28. IL-1β secretion was measured by ELISA following TLR1/2, TLR4 and TLR7/8 stimulation. The mRNA expression of SARM1, IL-1β and the components of the NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome were measured by quantitative PCR. SARM protein expression was measured by western blotting. TLR1/2 activation induced elevated IL-1β in RA monocytes compared with healthy controls (P = 0.0009), which negatively correlated with SARM1 expression (P = 0.0086). Lower SARM expression also correlated with higher disease activity (P = 0.0246). Additionally, patients responding to anti-TNF-α treatment demonstrated a rapid upregulation of SARM, which was not observed in non-responders. Together, these data highlight a potential contribution from SARM to RA pathophysiology where decreased SARM may lead to elevated IL-1β associated with RA pathogenesis. Furthermore, the data additionally present a potential mechanism by which TNF-α blockade can modify IL-1β secretion.

The incidence of and risk factors for exertional heat illness (EHI) and cold weather injury (CWI) in the U.S. Army have been well documented. The "heat season", when the risk of EHI is highest and application of risk mitigation procedures is mandatory, has been arbitrarily defined as May 1 through September 30, while the "cold season" is understood to occur from October 1 to April 30 each year. The proportions of EHI and CWI that occur outside of the traditional heat and cold seasons are unknown. Additionally, it is unknown if either of the seasonal definitions are appropriate. The primary purpose of this study was to determine the proportion of EHI and of CWI that occur within the commonly accepted seasonal definitions. We also report the location-specific variability, seasonal definitions, and the demographic characteristics of the populations. The U.S. Army installations with the highest frequency of EHI and of CWI from 2008 to 2013 were identified and used for analysis. In total there were 15 installae greater year-round emphasis, particularly at certain locations. The present study indicates that the traditional heat season definition should be revised to begin ∼3 weeks earlier than the current date of May 1; our data indicate that the current cold season definition is appropriate. Inter-installation variability in the start of the cold season was much larger than that for the heat season. Exertional heat illnesses are a year-round problem, with ∼17% of all cases occurring during non-summer months, when environmental heat strain and vigilance are lower. This suggests that EHI mitigation policies and procedures require greater year-round emphasis, particularly at certain locations.Chronic granulomatous disease is genetic disorder characterized by the inability of phagocytes to produce sufficient oxidative burst needed to kill intracellular organisms. Patients have recurrent, life-threatening infections involving multiple systems including the lungs, skin, lymph nodes, and liver. The majority of patients with chronic granulomatous disease are diagnosed in childhood although some may present in adulthood due to a milder phenotype. Unfortunately, these patients may also present with concomitant autoimmune diseases. We describe a 48-year-old woman with a history of immune thrombocytopenia and systemic lupus erythematosus on immunosuppressive therapy. She developed subsequent bacterial and fungal infections initially attributed to immunosuppressive drugs. Further evaluation revealed the diagnosis of chronic granulomatous disease. We review the diagnosis and treatment of chronic granulomatous disease in hopes to increase awareness of this disease in adulthood in order to initiate potential life-saving prophylactic antibiotics.
