Background: This study investigated the association between segmental phase angles and functional outcomes in patients after stroke, hypothesizing that increased segmental phase angle correlates with improved functional status.
Methods: A retrospective cohort study of 1012 patients after stroke was conducted. Whole body and segmental phase angles were measured using bioelectrical impedance analysis within 3 days of admission.
Article Synopsis
- - This study investigated how Stored Energy affects body weight (BW) and skeletal muscle mass (SMM) in stroke patients who also have sarcopenia, analyzing data from a Japanese rehabilitation hospital from 2015 to 2022.
- - Researchers calculated Total Stored Energy by subtracting energy requirements from energy intake, using multiple regression analysis to link Stored Energy levels to changes in BW and SMM during hospitalization.
- - Findings revealed that higher Stored Energy is significantly associated with increases in both BW and SMM, suggesting that energy reserves play a crucial role in recovery for patients post-stroke with sarcopenia.
Article Synopsis
- Sarcopenia and poor oral health are prevalent in older adults, especially in post-stroke patients, and their combined effect on rehabilitation outcomes is not well understood.
- A study of 1,012 post-stroke patients found that the coexistence of sarcopenia (45.6% prevalence) and impaired oral health (27.5% prevalence) led to significantly worse outcomes in daily living activities, cognition, and swallowing.
- Addressing both sarcopenia and oral health in rehabilitation could greatly improve recovery for these patients, highlighting the need for comprehensive assessments and targeted interventions.
Site-specific skeletal muscle mass and functional prognosis in geriatric stroke patients.
J Stroke Cerebrovasc Dis
December 2024
Background: Evidence is scarce regarding prognostic value of site-specific muscle mass in geriatric stroke survivors. We aim to assess the association between four measures of muscle mass, namely the skeletal muscle mass index of the limbs (SMI), upper limb SMI (USMI), lower limb SMI (LSMI), and trunk muscle mass index (TMI), and the functional prognosis in stroke patients.
Methods: This study conducted a retrospective cohort analysis involving post-acute stroke inpatients.
Objectives: There is a lack of evidence regarding the association between whole-body exercise and independence in urination and defecation. This study aimed to evaluate the effect of chair-stand exercise on improving urination and defecation independence in post-stroke patients with sarcopenia.
Methods: A retrospective study was conducted on stroke patients admitted to a community rehabilitation hospital between 2015 and 2021.
Aim: Low body mass index (BMI) and poor oral health are prevalent among older stroke patients and associated with adverse outcomes. However, their combined impact on functional recovery after stroke remains unclear. This study investigated the synergistic effects of low BMI and poor oral health on activities of daily living (ADL) independence, swallowing function, and cognitive status in post-stroke older patients.

We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients.
Methods: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients.
Article Synopsis
- - The study explores the effectiveness of a triad approach—rehabilitation, nutrition support, and oral management—in improving outcomes for post-stroke patients, who often struggle with malnutrition and related issues.
- - A cohort of 1,012 post-stroke patients was analyzed, showing that the triad approach significantly enhanced functional independence, muscle strength, and skeletal muscle mass compared to other interventions.
- - Results indicated that the triad approach was highly effective, with strong statistical associations linking it to better recovery outcomes, particularly in activities of daily living and physical strength.

Scope: Chalcones are widely present in most plants and have various health beneficial functions. This study investigates the suppressive effect of 13 natural and synthetic chalcones on transformation of aryl hydrocarbon receptor (AhR) induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 3-methylcholanthrene (3-MC) in a cell-free system, Hepa-1c1c7 cells, and liver of ICR mice.
Methods And Results: In the cell-free system, cardamonin dose-dependently inhibits AhR transformation.
Purpose: Evidence is scarce regarding the association between anemia and alterations in cognitive level among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in cognitive level in patients undergoing rehabilitation after stroke.
Methods: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients.
Article Synopsis
- This study investigates the impact of eruptive calcified nodules (CNs) on patient outcomes after percutaneous coronary intervention (PCI) compared to other calcified lesions, finding worse results for those with CNs.
- Researchers analyzed data from 51 patients who underwent PCI for calcified lesions, revealing that 54% of those with eruptive CNs had in-stent CNs at the 8-month follow-up, indicating more neointimal tissue growth.
- The results showed that patients with eruptive CNs experienced a significantly higher target lesion revascularization (TLR) rate both at 1 year (31.3%) and at 5 years (43.8%) compared
Article Synopsis
- The study investigates the relationship between hyponatremia (low sodium levels) and functional outcomes in older post-stroke patients during their hospital stay.
- It includes data from 955 patients, revealing that 8.8% had hyponatremia, which negatively impacted their ability to perform daily activities and muscle strength at discharge.
- The findings suggest that hyponatremia is linked to poorer rehabilitation outcomes, specifically in activities of daily living and handgrip strength, although there was no significant effect on skeletal muscle mass.
Background: Systemic inflammation is associated with poor functional outcomes. However, the effects of improved inflammation on functional indicators remain unclear. This study aimed to clarify the relationship between improvements in systemic inflammation and activities of daily living in patients after stroke.

We aimed to investigate the associations between hyponatremia and the baseline cognitive status, as well as the improvement in cognitive function, in hospitalized post-stroke patients.
Methods: This retrospective cohort study included consecutive hospitalized post-stroke patients.
Purpose: Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients.

Aim: The effects of statins on muscle health are not well established. Therefore, this study investigated the impact of statin use on muscle strength and mass recovery in patients with sarcopenia after stroke.
Methods: This retrospective cohort study included stroke patients with sarcopenia hospitalized between 2015 and 2021 at a post-acute rehabilitation hospital.
This study describes the rational design for the fabrication of bulk NiSn alloy catalysts for the de/hydration-hydrogenation of biomass-derived furfural (FFald) to 1,4-pentanediol (1,4-PeD) without the acidic co-catalyst. The presence of both hydration active sites (Brønsted acid sites (Ni-SnO)) and hydrogenation active sites (Ni or Ni-Sn alloy) in NiSn alloy could be controlled by changing the pH of Ni-Sn solution during the preparation. Both active sites acted synergistically to catalyse the de/hydration-hydrogenation reactions of FFald to produce a high yield of 1,4-PeD in a batch reaction system at 433 K, 3.

Article Synopsis
- A venous aneurysm is a localized dilation in major veins, with popliteal venous aneurysms (PVAs) being rare but serious as they can lead to deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE).
- A 21-year-old woman experienced a transient cardiac-pulmonary arrest due to a massive PTE caused by a thrombus from a right PVA, despite having no history of thrombotic issues.
- After treating her PTE and DVT with thrombolysis, surgical plication of the PVA was performed, and she has not had any recurrence of PTE or DVT in the subsequent two years, suggesting this surgical method may be an effective
