Physical strength and mental health mediate the association between pain and falls (recurrent and/or injurious) among community-dwelling older adults in Singapore.
No full textObjectiveThis study aims to understand if poor physical strength and depression mediate the association between pain and recurrent and/or injurious falls in a community of older adults.MethodsData was obtained from a nationally representative longitudinal cohort study conducted in Singapore, PHASE (Wave I and II), which collected information from community-dwelling older adults above 60 years old. A hurdle negative binomial regression and binomial logistic regression were used to assess the association between pain and recurrent falls, and pain and injurious falls respectively. A subsequent mediation analysis was conducted.ResultsAlmost half of the participants (N = 1144, 39.7%) reported having either mild, moderate, or severe pain at baseline, 166 (5.4%) participants experienced injurious falls and 144 (4.7%) participants experienced recurrent falls at Wave II. After adjusting for covariates, the presence of pain significantly influenced recurrent (OR 2.8; 95% CI: 1.8, 4.4) and injurious falls (OR: 1.8; 95% CI: 1.3, 2.5). Mediation analyses demonstrated that poor physical strength and depression had a significant mediation effect between all pain characteristics on recurrent falls. Poor physical strength partially mediates the effects of pain and injurious falls as well. However, the mediating effect of poor physical strength and depression was not observed between other pain characteristics and injurious falls.ConclusionsThe findings highlighted differences in the underlying mechanisms between pain characteristics affecting recurrent and injurious falls. These insights will be useful for identifying patients most at risk for recurrent or injurious falls, and for tailoring future community-based fall intervention programmes
Transforming growth factor-β-activated kinase 1 (TAK1) mediates chronic pain and cytokine production in mouse models of inflammatory, neuropathic, and primary pain.
No full textThe origin of chronic pain is linked to inflammation, characterized by increased levels of pro-inflammatory cytokines in local tissues and systemic circulation. Transforming growth factor beta-activated kinase 1 (TAK1) is a key regulator of pro-inflammatory cytokine signaling that has been well characterized in the context of cancer and autoimmune disorders, yet its role in chronic pain is less clear. Here, we evaluated the ability of our TAK1 small molecule inhibitor, takinib, to attenuate pain and inflammation in pre-clinical models of inflammatory, neuropathic, and primary pain. Inflammatory, neuropathic, and primary pain was modeled using intraplantar complete Freund's adjuvant (CFA), chronic constriction injury (CCI), and systemic delivery of the COMT inhibitor OR486, respectively. Behavioral responses evoked by mechanical and thermal stimuli were evaluated in separate groups of mice receiving takinib or vehicle prior to pain induction (baseline) and over 12 days following CFA injection, 4 weeks following CCI surgery, and 6 hours following OR486 delivery. Hindpaw edema was also measured prior to and 3 days following CFA injection. Upon termination of behavioral experiments, dorsal root ganglia (DRG) were collected to measure cytokines. We also evaluated the ability of takinib to modulate nociceptor activity via in vitro calcium imaging of neurons isolated from the dorsal root ganglia of Gcamp3 mice. In all three models, TAK1 inhibition significantly reduced hypersensitivity to mechanical and thermal stimuli and expression of pro-inflammatory cytokines in DRG. Furthermore, TAK1 inhibition significantly reduced the activity of tumor necrosis factor (TNF)-primed/capsaicin-evoked DRG nociceptive neurons. Overall, our results support the therapeutic potential of TAK1 as a novel drug target for the treatment of chronic pain syndromes with different etiologies. PERSPECTIVE: This article reports the therapeutic potential of TAK1 inhibitors for the treatment of chronic pain. This new treatment has the potential to provide a greater therapeutic offering to physicians and patients suffering from chronic pain as well as reduce the dependency on opioid based pain treatments
Developing Key Performance Indicators for Climate Change Adaptation and Resilience Planning
No full textThis document from the Resilience Roadmap project recommends a common approach to developing key performance indicators (KPIs) for climate change adaptation and resilience planning, drawing upon current science and tools referenced throughout. The work is particularly aimed to support climate adaptation and resilience planning by US federal agencies and thus presents principally US national-level data and online resources. The approach is broadly applicable across agencies, sectors, and systems and can also be applied by state or local planners and adaptation/resilience practitioners. The KPI development approach includes:
1. Setting the scope and goals of climate adaptation and resilience planning, following a stepwise process.
2. Developing KPIs to track performance and guide adaptive management, following a core set of ten process and five outcome indicators.
This methods brief includes contributions from Beth Gibbons, Lara Hansen, Jesse Keenan, Susanne Moser, Mark Rupp, Josh Sawislak, Laurie Schoeman, and Forbes Tompkins
Internal Medicine Resident Barriers to Advance Care Planning in the Primary Care Continuity Clinic
No full textBackground: While primary care providers regularly engage in Advance Care Planning (ACP) conversations, it is not well known what challenges resident physicians face to achieving this core competency. Objectives: We aimed to assess resident perceptions of barriers and potential interventions to outpatient ACP. Methods: We distributed an electronic survey to Internal Medicine and Medicine-Psychiatry residents at our institution in 2022. Questions addressed outpatient ACP barriers and potential interventions in several domains: structural issues, personal knowledge, and communication skills. We reported results using descriptive statistics and Wilcoxon rank-sum tests, comparing responses by residency year (interns vs upperyears). Likert-scale responses were dichotomized to a “not at all or slightly” vs “moderate or extreme” barrier or helpful intervention. Results: Of 149 residents, 71 completed the survey (48%). Highest scoring barriers were structural, including 1) lack of clinic time (99%), 2) need to prioritize other medical problems (94%), and 3) lack of patient continuity (62%). Highest scoring interventions included the ability to schedule dedicated ACP visits with themselves (96%) or another clinician (82%). Interns were statistically significantly less confident in their ability to conduct ACP, and more likely to report lack of knowledge (i.e., not understanding ACP, patient prognosis, or how to complete paperwork, P <.05). Conclusions: Residents report significant structural barriers to outpatient ACP, including limitations in time, continuity, and competing medical priorities, that may warrant greater program attention to interventions such as clinic schedules and work-flow. Additional trainings may be most beneficial if targeted to the beginning of intern year
Crisis: Masculinity and an Ethic of Care in American Literature
No full textThis dissertation takes three crisis periods that have occurred throughout American history—times of war, times of disease, and times of apocalypse—and examines how such periods simultaneously provoke what can be called “traditional” masculine responses of toughness, independence, and executive action along with an alternative gender expression contemporary sociologists refer to as caring masculinity. Rather than consider caring masculinity a new phenomenon, Crisis: Masculinity and an Ethic of Care in American Literature seeks to establish the extended and underexplored history of manhood’s intersection with relational forms of care as expressed in popular literature. By analyzing literary works spanning from the nineteenth century to the twenty-first century, Crisis argues that such patterns of practice have existed in many forms, across a variety of situation, and for a long time.</p
Use of Innovative Technologies in Pediatric Lower Extremity Reconstruction.
No full textThe anterolateral thigh (ALT) free flap has proven to be a reliable option for the coverage of soft tissue defects in adults and more recently in the pediatric population. When considering the use of the ALT flap in the pediatric patient, there are few studies that detail techniques specific to pediatric free flap management. We present a unique case of a 14- × 8-cm ALT flap used for traumatic wound coverage in a distal tibial injury in a 6-year-old girl. This case highlights innovative techniques in pediatric perioperative free flap monitoring and the use of continuous external tissue expansion to achieve delayed primary closure of the donor site
Effect of behavioral weight-loss program on biomarkers of cardiometabolic disease risk: Heart Health Study randomized trial.
No full textObjectiveThis study aimed to determine whether novel biomarkers of cardiometabolic health improve in response to a 12-month behavioral weight-loss intervention and to compare benefits of diet alone with diet plus physical activity for these biomarkers.MethodsParticipants (N = 374) were randomized to either diet alone (DIET), diet plus 150 min/wk of prescribed moderate-intensity physical activity (DIET + PA150), or diet plus 250 min/wk of prescribed moderate-intensity physical activity (DIET + PA250). Biomarker concentrations were determined using nuclear magnetic resonance spectroscopy. Mixed models assessed for a time effect, group effect, or group by time interaction.ResultsAll groups significantly improved body weight (time: p ConclusionsAll intervention groups prompted a notable beneficial change among biomarkers of insulin resistance and cardiometabolic health. However, the addition of at least moderate-intensity physical activity to a diet-only intervention did not provide any additional benefit. These findings highlight that an average weight loss of approximately 10% profoundly impacts biomarkers of insulin resistance and cardiometabolic disease in adults with overweight or obesity
Social determinants of health as drivers of fungal disease
No full textDisparities in social determinants of health (SDOH) play a significant role in causing health inequities globally. The physical environment, including housing and workplace environment, can increase the prevalence and spread of fungal infections. A number of professions are associated with increased fungal infection risk and are associated with low pay, which may be linked to crowded and sub-optimal living conditions, exposure to fungal organisms, lack of access to quality health care, and risk for fungal infection. Those involved and displaced from areas of armed conflict have an increased risk of invasive fungal infections. Lastly, a number of fungal plant pathogens already threaten food security, which will become more problematic with global climate change. Taken together, disparities in SDOH are associated with increased risk for contracting fungal infections. More emphasis needs to be placed on systematic approaches to better understand the impact and reducing the health inequities associated with these disparities
Acute Kidney Injury after Lung Transplantation: A Systematic Review and Meta-Analysis.
No full textLung transplantation has been increasingly performed worldwide and is considered an effective therapy for patients with various causes of end-stage lung diseases. We performed a systematic review to assess the incidence and impact of acute kidney injury (AKI) and severe AKI requiring renal replacement therapy (RRT) in patients after lung transplantation. A literature search was conducted utilizing Ovid MEDLINE, EMBASE, and Cochrane Database from inception through June 2019. We included studies that evaluated the incidence of AKI, severe AKI requiring RRT, and mortality risk of AKI among patients after lung transplantation. Pooled incidence and odds ratios (ORs) with 95% confidence interval (CI) were obtained using random-effects meta-analysis. The protocol for this meta-analysis is registered with PROSPERO (International Prospective Register of Systematic Reviews; no. CRD42019134095). A total of 26 cohort studies with a total of 40,592 patients after lung transplantation were enrolled. Overall, the pooled estimated incidence rates of AKI (by standard AKI definitions) and severe AKI requiring RRT following lung transplantation were 52.5% (95% CI: 45.8-59.1%) and 9.3% (95% CI: 7.6-11.4%). Meta-regression analysis demonstrated that the year of study did not significantly affect the incidence of AKI (p = 0.22) and severe AKI requiring RRT (p = 0.68). The pooled ORs of in-hospital mortality in patients after lung transplantation with AKI and severe AKI requiring RRT were 2.75 (95% CI, 1.18-6.41) and 10.89 (95% CI, 5.03-23.58). At five years, the pooled ORs of mortality among patients after lung transplantation with AKI and severe AKI requiring RRT were 1.47 (95% CI, 1.11-1.94) and 4.79 (95% CI, 3.58-6.40), respectively. The overall estimated incidence rates of AKI and severe AKI requiring RRT in patients after lung transplantation are 52.5% and 9.3%, respectively. Despite advances in therapy, the incidence of AKI in patients after lung transplantation does not seem to have decreased. In addition, AKI after lung transplantation is significantly associated with reduced short-term and long-term survival
Limited morbidity and possible radiographic benefit of C2 vs. subaxial cervical upper-most instrumented vertebrae
No full textBackground: The study aims to evaluate differences in alignment and clinical outcomes between surgical cervical deformity (CD) patients with a subaxial upper-most instrumented vertebra (UIV) and patients with a UIV at C2. Use of CD-corrective instrumentation in the subaxial cervical spine is considered risky due to narrow subaxial pedicles and vertebral artery anatomy. While C2 fixation provides increased stability, the literature lacks guidelines indicating extension of CD-corrective fusion from the subaxial spine to C2. Methods: Included: operative CD patients with baseline (BL) and 1-year postop (1Y) radiographic data, cervical UIV ≥ C2. Patients were grouped by UIV: C2 or subaxial (C3-C7) and propensity score matched (PSM) for BL cSVA. Mean comparison tests assessed differences in BL and 1Y patient-related, radiographic, and surgical data between UIV groups, and BL-1Y changes in alignment and clinical outcomes. Results: Following PSM, 31 C2 UIV and 31 subaxial UIV patients undergoing CD-corrective surgery were included. Groups did not differ in BL comorbidity burden (P=0.175) or cSVA (P=0.401). C2 patients were older (64 vs. 58 yrs, P=0.010) and had longer fusions (9 vs. 6 levels, P=0.002). Overall, patients showed BL-1Y improvements in TS-CL (P0.05). Conclusions: C2 UIV patients showed similar cervical range of motion and baseline to 1-year functional outcomes as patients with a subaxial UIV. C2 UIV patients also showed greater baseline to 1-year horizontal gaze improvement and had complication profiles similar to subaxial UIV patients, demonstrating the radiographic benefit and minimal functional loss associated with extending fusion constructs to C2. In the treatment of adult cervical deformities, extension of the reconstruction construct to the axis may allow for certain clinical benefits with less morbidity than previously acknowledged
