Patients with Parkinson’s disease may have impaired ability to respond normally to a fall in blood pressure after standing from lying down or seated position. Patients on ropinirole should be monitored for signs and symptoms of orthostatic hypotension, especially during dose escalation, and should be informed of the risk for syncope and hypotension [see Patient Counseling Information (17)].

Although the clinical trials were not designed to systematically monitor blood pressure, there were individual reported cases of orthostatic hypotension in early Parkinson’s disease (without L-dopa) in patients treated with ropinirole. Most of these cases occurred more than 4 weeks after initiation of therapy with ropinirole and were usually associated with a recent increase in dose.

In 12-week, placebo-controlled trials of patients with RLS, the adverse event orthostatic hypotension was reported by 4 of 496 patients (0.8%) treated with ropinirole compared with 2 of 500 patients (0.4%) receiving placebo.

In 2 Phase 2 trials in patients with RLS, 14 of 55 patients (25%) receiving ropinirole experienced an adverse event of hypotension or orthostatic hypotension compared with none of the 27 patients receiving placebo. In these trials, 11 of the 55 patients (20%) receiving ropinirole and 3 of the 26 patients (12%) who had post-dose blood pressure assessments following placebo experienced an orthostatic blood pressure decrease of at least 40 mm Hg systolic and/or at least 20 mm Hg diastolic.

In Phase 1 trials of ropinirole with healthy volunteers who received single doses on more than one occasion without titration, 7% had documented symptomatic orthostatic hypotension. These episodes appeared mainly at doses above 0.8 mg, and these doses are higher than the starting doses recommended for patients with either Parkinson’s disease or with RLS. In most of these individuals, the hypotension was accompanied by bradycardia but did not develop into syncope [see Warnings and Precautions (5.2)].

Although dizziness is not a specific manifestation of hypotension or orthostatic hypotension, patients with hypotension or orthostatic hypotension frequently reported dizziness. In controlled clinical trials, dizziness was a common adverse reaction in patients receiving ropinirole and was more frequent in patients with Parkinson’s disease or with RLS receiving ropinirole than in patients receiving placebo (early Parkinson’s disease without L-dopa: Ropinirole 40%, placebo 22%; advanced Parkinson’s disease: Ropinirole 26%, placebo 16%; RLS: Ropinirole 11%, placebo 5%). Dizziness of sufficient severity to cause trial discontinuation of ropinirole was 4% in patients with early Parkinson’s disease without L-dopa, 3% in patients with advanced Parkinson’s disease, and 1% in patients with RLS [see Adverse Reactions (6.1)].
BACKGROUND: Commotio cordis, sudden cardiac death (SCD) caused by relatively innocent impact to the chest, is one of the leading causes of SCD in sports. Commercial chest protectors have not been demonstrated to mitigate the risk of these SCDs.
METHODS: To develop a standard to assess chest protectors, 4 phases occurred. A physiological commotio cordis model was utilized to assess variables that predicted for SCD. Next, a surrogate model was developed based on data from the physiological model, and the attenuation in risk was assessed. In the third phase, this model was calibrated and validated. Finally, National Operating Committee on Standards for Athletic Equipment adopted the standard and had an open review process with revision of the standard over 3 years.
RESULTS: Of all variables, impact force was the most robust at predicting SCD. Chest wall protectors which could reduce the force of impact to under thresholds were predicted to reduce the risk of SCD. The correlation between the experimental model and the mechanical surrogate ranged from 0.783 with a lacrosse ball at 30 mph to 0.898 with a baseball at 50 mph. The standard was licensed to National Operating Committee on Standards for Athletic Equipment which initially adopted the standard in January 2018, and finalized in July 2021.
CONCLUSIONS: An effective mechanical surrogate based on physiological data from a well-established model of commotio cordis predicts the reduction in SCD with chest protectors. A greater reduction in force provides a great degree of protection from commotio cordis. This new National Operating Committee on Standards for Athletic Equipment standard for chest protectors should result in a significant reduction in the risk of commotio cordis on the playing field.
Angiosarcoma is a rare refractory soft-tissue tumor with a poor prognosis and is treated by radiotherapy. The fibroblast growth factor 1 (FGF1) mutant, with enhanced thermostability due to several substituted amino acids, inhibits angiosarcoma cell metastasis, yet the mechanism of action is unclear. This study aims to clarify the FGF1 mutant mechanism of action using ISOS-1 mouse angiosarcoma cells. The wild-type FGF1 or FGF1 mutant was added to ISOS-1 cells and cultured, evaluating cell numbers over time. The invasive and migratory capacity of ISOS-1 cells was assessed by transwell analysis. ISOS-1 cell radiosensitivity was assessed by colony formation assay after X-ray irradiation. To examine whether mitogen-activated protein kinase (MEK) inhibitor counteracts the FGF1 mutant effects, a combination of MEK inhibitor and FGF1 mutant was added to ISOS-1 cells and cultured. The FGF1 mutant was observed to inhibit ISOS-1 cell proliferation, invasion and migration by sustained FGF1 signaling activation. A MEK inhibitor suppressed the FGF1 mutant-induced inhibition of proliferation, invasion and migration of ISOS-1 cells. Furthermore, the FGF1 mutant enhanced radiosensitivity of ISOS-1 cells, but MEK inhibition suppressed the increased radiosensitivity. In addition, we found that the FGF1 mutant strongly inhibits actin polymerization, suggesting that actin cytoskeletal dynamics are closely related to ISOS-1 cell radiosensitivity. Overall, this study demonstrated that in ISOS-1 cells, the FGF1 mutant inhibits proliferation, invasion and migration while enhancing radiosensitivity through sustained activation of the MEK-mediated signaling pathway.
Medicare Advantage (MA) supplemental benefits offered at no or low premiums are a key value proposition for low-income beneficiaries. Despite nearly $20 billion in rebate payments to MA plans for funding supplemental benefits, their quality or enrollee access is not monitored. Using 2018-19 Medicare Current Beneficiary Survey data linked to MA plan data, we found that regardless of plan benefit generosity, low-income beneficiaries were more likely to report dental, vision, and hearing unmet needs because of cost. Enrollment in plans with higher corresponding-year (that is, the same year as unmet need measurement) star ratings was associated with lower dental unmet need. Income-related disparities in dental unmet needs were lower in the highest-rated plans. However, prior-year star ratings that determined plan payments were not associated with unmet needs or disparities in those needs. Policy makers should consider monitoring supplemental benefits for equity and access, and they should assess the value added by quality bonus payments to high-rated plans for beneficiaries' access.
UNLABELLED: Facultative endosymbiotic bacteria, such as Wolbachia and Spiroplasma species, are commonly found in association with insects and can dramatically alter their host physiology. Many endosymbionts are defensive and protect their hosts against parasites or pathogens. Despite the widespread nature of defensive insect symbioses and their importance for the ecology and evolution of insects, the mechanisms of symbiont-mediated host protection remain poorly characterized. Here, we utilized the fruit fly Drosophila melanogaster and its facultative endosymbiont Spiroplasma poulsonii to characterize the mechanisms underlying symbiont-mediated host protection against bacterial and fungal pathogens. Our results indicate a variable effect of S. poulsonii on infection outcome, with endosymbiont-harboring flies being more resistant to Rhyzopus oryzae, Staphylococcus aureus, and Providencia alcalifaciens but more sensitive or as sensitive as endosymbiont-free flies to the infections with Pseudomonas species. Further focusing on the protective effect, we identified Transferrin-mediated iron sequestration induced by Spiroplasma as being crucial for the defense against R. oryzae and P. alcalifaciens. In the case of S. aureus, enhanced melanization in Spiroplasma-harboring flies plays a major role in protection. Both iron sequestration and melanization induced by Spiroplasma require the host immune sensor protease Persephone, suggesting a role of proteases secreted by the symbiont in the activation of host defense reactions. Hence, our work reveals a broader defensive range of Spiroplasma than previously appreciated and adds nutritional immunity and melanization to the defensive arsenal of symbionts.
IMPORTANCE: Defensive endosymbiotic bacteria conferring protection to their hosts against parasites and pathogens are widespread in insect populations. However, the mechanisms by which most symbionts confer protection are not fully understood. Here, we studied the mechanisms of protection against bacterial and fungal pathogens mediated by the Drosophila melanogaster endosymbiont Spiroplasma poulsonii. We demonstrate that besides the previously described protection against wasps and nematodes, Spiroplasma also confers increased resistance to pathogenic bacteria and fungi. We identified Spiroplasma-induced iron sequestration and melanization as key defense mechanisms. Our work broadens the known defense spectrum of Spiroplasma and reveals a previously unappreciated role of melanization and iron sequestration in endosymbiont-mediated host protection. We propose that the mechanisms we have identified here may be of broader significance and could apply to other endosymbionts, particularly to Wolbachia, and potentially explain their protective properties.

OBJECTIVES: Parkinsonian syndromes are disabling neurodegenerative diseases resulting in reduced muscle function/performance and sarcopenia, but clinical manifestations could be systemic, including deterioration of cognitive function. As studies have reported an association between muscle dysfunction and cognitive decline yet no information on these syndromes is available, we investigated the relationship between sarcopenia, its components, and cognitive function, fatigue, and quality of life (QoL).
METHODS: Consecutive patients affected by parkinsonian syndromes were assessed for the presence of sarcopenia using the European Working Group on Sarcopenia in Older People-2 algorithm: low strength (handgrip strength: <27 kg [men]; <16 kg [women]) and low appendicular skeletal muscle index by impedance (<7.0 kg/m2 [men]; <6.0 kg/m2 [women]). Cognitive function was evaluated using the Montreal Cognitive Assessment, the Mini Mental State Examination and the Frontal Assessment Battery. Fatigue and QoL were assessed using the 16-item Parkinson's Disease Fatigue Scale and the 39-item Parkinson's Disease Questionnaire, respectively.
RESULTS: In total, 314 patients were included: 198 presented with low strength (63.0% probable sarcopenia); 68 (21.7%) of these were diagnosed with sarcopenia. After adjusting for multiple confounders, we observed a significant effect (poorer score) of both low strength only and sarcopenia on Montreal Cognitive Assessment, Mini Mental State Examination, and QoL. Only reduced muscle strength had a relevant impact on the outcomes considered.
CONCLUSIONS: Sarcopenia is associated with worse cognitive functions and QoL in patients with parkinsonian syndromes, with muscle dysfunction playing a major role. The prognostic impact of sarcopenia and its components should be addressed in prospective studies.

Calcium (Ca) is necessary for bone calcification, and Ca deficiency leads to decreased bone mineral density (BMD). Epidemiological studies have reported a correlation between Ca intake and BMD. Although the influences of Ca deficiency on BMD have been reported, the effects of Ca restriction on bone during high-fat diet ingestion remain unclear. Therefore, we hypothesized that high-fat diet ingestion would potentiate the negative effects of Ca restriction on bone. Sprague-Dawley strain male rats (aged 11 weeks) were divided into 4 groups: basic control diet (Cont.) (11% lipid energy rate, 0.5% calcium), basic control diet with Ca restriction (CaR) (11% lipid energy rate, 0.02% calcium), high-fat diet (HF) (40% lipid energy rate, 0.5% calcium), and high-fat diet with Ca restriction (HFCaR) (40% lipid energy rate, 0.02% calcium). At 28 days after starting the experimental diets, body weights were higher in the high-fat diet groups (HF and HFCaR) than in the standard-fat diet groups (Cont. and CaR) on 2-way analysis of variance. The apparent Ca absorption rate in the Ca-restricted groups (CaR and HFCaR) was higher than in the Ca-sufficient groups (Cont. and HF). BMD and bone strength parameters of the femur and lumbar vertebrae in the Ca-restricted groups were markedly lower than in the Ca-sufficient groups, whereas there were no significant differences between the standard-fat diet and HF diet groups. These results suggest that 28 days of Ca restriction increases the risk of bone fracture and osteoporosis.

Rates of pediatric overweight (PO) among Americans are increasing and associated with significant psychological, social, quality of life, and health related outcomes. Because of the broad mental and physical health implications of PO and the difficulty in sustaining weight loss as an adult, it is of interest to find successful methods of weight loss and/or prevention of weight gain for obese children and adolescents. The family unit is a logical and empirically supported point of intervention for PO. Interventions on this level have shown good long term efficacy in young children, but there is very little research on adolescent family intervention. Within the eating disorder literature, there is growing support for the efficacy of family-based interventions (FBI) for adolescents. Given its trans-developmental applicability, focus on family as the unit of intervention, and utility in creating a healthy eating environment, FBI is a logical candidate for adaptation to intervention for PO and intervention for at-risk for overweight youth (FBI-PO). The core of the current project is to test the feasibility and efficacy of an adapted FBI manual for adolescent overweight and at-risk for overweight in an outpatient eating and weight disorders clinic and compare this modality to a minimal nutritional educational control (NEC) condition.
