[PMID: 39016169 PMCID: PMC11253024 DOI: 10.14814/phy2.16153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 07/08/2024] [Accepted: 07/08/2024] [Indexed: 07/18/2024] Open
Abstract
Stroke is not only associated with muscle weakness, but also associated with reduced muscle fatigue resistance and reduced desaturation during exercise that may be caused by a reduced oxidative capacity and/or microvasculature. Therefore, the objective of the present study was to determine the effects of stroke on muscle mass, fiber size and shape, capillarization and oxidative capacity of the rat m. extensor carpi radialis (ECR) and m. flexor carpi ulnaris (FCU) after a photothrombotic stroke in the forelimb region of the primary sensorimotor cortex. The main observation of the present study was that 4 weeks after induction of stroke there were no significant changes in muscle fiber size and shape. Although there was no significant capillary rarefaction, there was some evidence for remodeling of the capillary bed as reflected by a reduced heterogeneity of capillary spacing (p = 0.006) that may result in improved muscle oxygenation. In the ECR, but not in the FCU, this was accompanied by reduction in muscle fiber oxidative capacity as reflected by reduced optical density of sections stained for succinate dehydrogenase (p = 0.013). The reduced oxidative capacity and absence of significant capillary rarefaction resulted in a capillary to fiber ratio per unit of oxidative capacity that was higher after stroke in the ECR (p = 0.01), but not in the FCU. This suggests that at least during the early stages, stroke is not necessarily accompanied by muscle fiber atrophy, and that stroke-induced reductions in oxidative capacity resulting in relative excess of capillarization are muscle specific.

Tento T, Kume A, Kumaso S. Risk factors for stroke-related functional disability and mortality at Felege Hiwot Referral Hospital, Ethiopia. BMC Neurol 2023; 23:393. [PMID: 37907867 PMCID: PMC10617073 DOI: 10.1186/s12883-023-03444-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 10/20/2023] [Indexed: 11/02/2023] Open
Abstract
BACKGROUND Stroke is one of the top causes of functional disability around the world. The main objective was to identify stroke-related functional outcomes and risk factors. A good functional outcome is defined as the absence of problems secondary to the stroke event, a poor functional outcome as the presence of complications, and mortality as the existence of complications. METHOD A retrospective cohort analysis was used to observe factors in 298 eligible adult (18 or older) stroke patients who attend outpatient clinics every three months at Felege Hiwot Referral Hospital between September 2019 and August 2021 to predict outcomes. RESULT The likelihood of dying from a poor outcome was 9%, and the likelihood of recovering was 24%. The average time spent on good and poor outcomes for different levels of independent variables varies according to their risk. During the first three years of follow-up, the instantaneous risk with a 95% confidence interval of transitioning from good to poor outcome in the women, aged 60 or older, with hypertension, atrial fibrillation, and hemorrhage stroke versus men stroke patients, aged 18 to 59, without hypertension, atrial fibrillation, and ischemic stroke were 1.54 (1.10, 2.15), 1.73 (1.19, 2.52), 2.34 (1.55, 3.53), 2.74 (1.64, 4.56), and 1.52 (1.10, 2.19) respectively. The hazard ratio of transitioning from poor outcome to death for patients with diabetes mellitus and atrial fibrillation versus those without diabetes mellitus and atrial fibrillation was estimated to be 1.95 (1.10, 3.46) and 3.39 (1.67, 6.89), respectively. CONCLUSION Women over 60 with hypertension, atrial fibrillation, and hemorrhagic stroke were more likely to progress from a good to a poor outcome. Diabetes and atrial fibrillation were also risk factors for progressing from a poor outcome to death. The states and transitions, as well as a clinical control of the hazards for the transition through states, should improve the physician's decision-making process. Since gender and age are difficult to control, early intervention by patients and the hospital may be critical in influencing functional outcomes.

Abstract
INTRODUCTION The role of COVID-19 regarding in-hospital complications and poor outcomes for patients with ischaemic stroke (IS) is still important to explore. The aim of this study was to evaluate the risk of in-hospital lethality for IS patients respectively to their comorbidities and in-hospital complications in the context of the COVID-19 pandemic. METHODS We identified 1898 acute IS patients (749 men and 1149 women) admitted to the Lithuanian University of Health Sciences Kaunas Hospital, Lithuania, from December 2020 to February 2022. The sociodemographic, clinical, and outcome features of the patients were evaluated deploying appropriate statistical tests. Hazard ratios and 95% confidence intervals were estimated by the Cox proportional hazards regression for hospital lethality. RESULTS The risk of in-hospital lethality was 2.22 times higher in men suffering from IS and chronic ischaemic heart disease (cIHD) compared to those with IS and isolated arterial hypertension (iAH) (p < 0.05). COVID-19 elevated the risk of in-hospital lethality in men by 3.16 times (p < 0.05). In comorbid women with type two diabetes mellitus (DM) or cIHD, the risk of in-hospital lethality was two times higher compared to those with iAH (p < 0.05). The risk of in-hospital lethality increased significantly in both men and women, with the total number of in-hospital complications increasing per one unit. CONCLUSIONS Of the comorbidities studied, DM and cIHD together with COVID-19 elevated the risk of in-hospital lethality significantly. Within the acute in-hospital complications, pneumonia with respiratory failure and acute renal failure showed the most significant prognostic value anticipating lethal outcomes for IS patients.

Abstract
There is a lack of information on the epidemiology of acute ischemic stroke (AIS), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH) in developing countries. This research presents incidence and mortality rates of stroke patients based on hospital admission and discharge status in one of the Central Asian countries by analysis of large-scale healthcare data. The registry data of 177,947 patients admitted to the hospital with the diagnosis of stroke between 2014 and 2019 were extracted from the National Electronic Health System of Kazakhstan. We provide descriptive statistics and analyze the association of socio-demographic and medical characteristics such as comorbidities and surgical treatments. Among all stroke patients, the incidence rate based on hospital admission of AIS was significantly higher compared to SAH and ICH patients. In 5 year follow-up period, AIS patients had a better outcome than SAH and ICH patients (64.7, 63.1 and 57.3% respectively). The hazard ratio (HR) after the trepanation and decompression surgery was 2.3 and 1.48 for AIS and SAH patients; however, it was protective for ICH (HR = 0.87). The investigation evaluated an increase in the all-cause mortality rates based on the discharge status of stroke patients, while the incidence rate decreased over time.

Abstract
AbstractThe stroke incidence has increased rapidly in South Korea, calling for a national-wide system for long-term stroke management. We investigated the effects of socioeconomic status (SES) and geographic factors on chronic phase survival after stroke. We retrospectively enrolled 6994 patients who experienced a stroke event in 2009 from the Korean National Health Insurance database. We followed them up from 24 to 120 months after stroke onset. The endpoint was all-cause mortality. We defined SES using a medical-aid group and four groups divided by health insurance premium quartiles. Geographic factors were defined using Model 1 (capital, metropolitan, city, and county) and Model 2 (with or without university hospitals). The higher the insurance premium, the higher the survival rate tended to be (P < 0.001). The patient survival rate was highest in the capital city and lowest at the county level (P < 0.001). Regions with a university hospital(s) showed a higher survival rate (P = 0.006). Cox regression revealed that the medical-aid group was identified as an independent risk factor for chronic phase mortality. Further, NHIP level had a more significant effect than geographic factors on chronic stroke mortality. From these results, long-term nationwide efforts to reduce inter-regional as well as SES discrepancies affecting stroke management are needed.

Abstract
PURPOSE The aim of this study was to assess the effects of experimentally induced photothrombotic stroke on structural and mechanical properties of rat m. flexor carpi ulnaris. METHODS Two groups of Young-adult male Sprague-Dawley rats were measured: stroke (n = 9) and control (n = 7). Photothrombotic stroke was induced in the forelimb region of the primary sensorimotor cortex. Four weeks later, muscle-tendon unit and muscle belly length-force characteristics of the m. flexor carpi ulnaris, mechanical interaction with the neighbouring m. palmaris longus, the number of sarcomeres in series within muscle fibres, and the physiological cross-sectional area were measured. RESULTS Stroke resulted in higher force and stiffness of the m. flexor carpi ulnaris at optimum muscle-tendon unit length, but only for the passive conditions. Stroke did not alter the length-force characteristics of m. flexor carpi ulnaris muscle belly, morphological characteristics, and the extent of mechanical interaction with m. palmaris longus muscle. CONCLUSION The higher passive force and passive stiffness at the muscle-tendon unit level in the absence of changes in structural and mechanical characteristics of the muscle belly indicates that the experimentally induced stroke resulted in an increased stiffness of the tendon.

Abstract
INTRODUCTION Stroke is one of the commonest non-communicable disease types that has a great public health impact both in developed and developing countries. However, in Ethiopia, the long-term survival status of stroke patients is not very understood. This study aimed at assessing survival status and predictors of mortality among stroke patients at Felege Hiwot comprehensive specialized hospital from September 1, 2014, to August 31, 2019, Bahirdar, North West Ethiopia. METHODS An institutional-based retrospective cohort study was conducted using 368 registered stroke patients between September 1, 2014, and August 31, 2019. We used Kaplan-Meier together with a Log-rank test to compare the survival rate of the study participants using categorical variables and to compare covariate and both bi-variable and multivariable Cox proportional hazards regression analysis model was conducted to identify predictors of mortality among stroke patients. The association between outcome and independent variables was expressed using an adjusted hazard ratio (AHR) with a 95% confidence interval and statistical significances were declared at P-value of <0.05. RESULTS Fifty-six (15.2%) of the 368 stroke patients included in the study died, and 312 (84.8%) were correctly censored. The overall survival rate was 72.2% at 51 months of follow-up with a median survival time of 0.26 months. Age greater than 65 (AHR 6.31, 95% CI 1.75-22.74), body temperature >7.1 degree centigrade (AHR = 7.14, 95% CI: 2.76-18.5), potassium level below <2 mmol/l (AHR = 2, 95% CI: 1.9-23.53) and creatinine level >1.2 mg/dl (AHR = 7.85, 95% CI: 2.7-22.6) were predictive predictors of mortality. CONCLUSIONS In the follow-up of 51 months, significant mortality occurred. Important predictive predictors of survival status were identified. Interventions should be focused on health education and awareness creation of the community for the early management of stroke.

Abstract
Aim. To conduct a comparative analysis of clinical and anamnestic characteristics, risk factors, pharmacotherapy and outcomes in patients with previous stroke and myocardial infarction (MI) in outpatient practice based on data from prospective outpatient registries.Material and methods. On the basis of three outpatient clinics in Ryazan, based on the results of treatment in 2012-2013, an outpatient registry of patients who had stroke of any remoteness (REGION-AR) and an outpatient registry of patients who had previous myocardial infarction (REGATA) were created, which included, respectively, 511 patients (212 men, 41.5%) and 481 patients (247 men, 51.4%). Clinical and anamnestic characteristics, risk factors, prescribed pharmacotherapy, and its compliance with clinical guidelines were evaluated.Results. Most of the patients in the REGION-AR and REGATA registries were diagnosed with arterial hypertension (AH; 97.1% and 98.5%), coronary heart disease (СHD; 75.1% and 100%), chronic heart failure (CHF; 74.0% and 94.8%), and the proportion of atrial fibrillation (AF) cases were 20.9% and 23.3%, respectively. The share of smokers was significantly higher (23.4% vs 8.9%; p<0.0001) in the REGATA registry, and the share of people with high blood pressure at the inclusion visit (82.6% vs 67.6 %; p<0.0001) and hypercholesterolemia (63.8% vs 45.8%; p<0.0001) was higher in the REGION-AR registry. In both registries, there was a generally insufficient frequency of proper medication prescriptions, while patients in the REGION registry were statistically significantly less likely to receive mandatory prescriptions in general (44.4% vs 58.2%, p<0.0001), including antihypertensive therapy for hypertension, as well as angiotensin-converting-enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) in CHF, beta-blockers in CHF and MI history, statins in CHD, antiplatelet agents in CHD without AF. Over 3 years of follow-up, the degree of compliance of drug prescriptions with clinical recommendations increased both in the REGION-AR registry (from 44.4% to 58.2%) and in the REGATA registry (from 58.2% to 62.9%). For 36 months of prospective observation in the REGION-AR registry, as compared to the REGATA registry, there was a higher mortality rate (22.1% vs 17.0%; p=0.04), moreover the mortality rate among men was higher (22.2% vs 14.2%; p=0.03), and among women it did not differ significantly (22.1% and 20.0%; p=0.56).Conclusion. Outpatient registries of patients who survived after acute cerebrovascular accident and myocardial infarction were comparable in terms of the average age of patients, however, women prevailed in the REGION-AR study, and men - in the REGATA registry. In the registry of patients who had myocardial infarction, СHD, CHF, respiratory and digestive system diseases, chronic kidney disease, obesity were more often diagnosed, less often – heart defects and oncological diseases. This category of patients was more often prescribed ACE inhibitors/ARBs, beta-blockers, statins, antiplatelet agents. The proportion of compliance of prescriptions with clinical guidelines was higher in the registry of patients who underwent MI both at the stage of inclusion and during subsequent prospective observation. In both registries, an improvement in the quality of drug therapy was noted after 3 years of follow-up. Mortality from all causes over 3 years of follow-up was significantly higher in the registry of post-stroke patients compared to the registry of those with MI, and this was due to the higher mortality in men (1.6 times), but among women in the compared studies the death rate did not differ significantly.

Abstract
Aim. To estimate outcomes and risk of all-cause mortality, cardiovascular (CV) mortality, and non-fatal CV events in patients with a history of acute cerebrovascular accident (ACVA) according to data of outpatient prospective registries.Material and methods. 986 patients with a history of ACVA (aged 70.6Ѓ}10.9 years; 56.8% women) were enrolled into the outpatient registry REGION-Ryazan, including the registry of patients with ACVA of any remoteness (ACVA-AR) – 511 (aged 70.4Ѓ}10.5 years; 58.5% women) and the registry of patients, visited outpatient clinics for the first time after ACVA (ACVA-FT) – 475 (aged 70.8Ѓ}11.3 years; 54.9% women). Outcomes, risk of all-cause and CV mortality, composite CV endpoint (CV death, nonfatal myocardial infarction and ACVA), hospitalizations due to CV diseases (CVD) were evaluated during 37 (17;52) months of follow-up period.Results. 310 (31.2%) patients died during the follow-up. The most part of fatal outcomes (56.4%) was registered during the first year of follow-up, especially during the first 3 months (33.9%). Mortality among men (35.9%) was higher than among women (28.0%), р=0.008. 147 (28.8%) and 163 (34.3%) patients died in registries ACVA-AR and ACVA-FT, respectively (70.4% and 90.2% of fatal outcomes were from CV causes, respectively; р=0.04). The higher risk of death was associated with the following factors: age – hazard ratio (HR) 1.10 for each next year of age (95% confidence interval [95%CI] 1.09-1.12); sex (men) – HR 2.01 (95%CI 1.55-2.62); atrial fibrillation (AF) – HR 1.42 (95%CI 1,09-1,86); recurrent ACVA – HR 1.64 (95%CI 1.23-2.19); history of myocardial infarction (MI) – HR 1.45 (95%CI 1.09-1.93); low blood hemoglobin level – HR 2.44 (95%CI 1.59-3.79); heart rate ≥80 beats/min – HR 1.51 (95%CI 1.13-2.03); diabetes – HR 1.56 (95%CI 1.16-2.08); chronic obstructive pulmonary disease (COPD) – HR 1.89 (95%CI 1.34-2.66); no antihypertensive therapy in arterial hypertension – HR 2.03 (95%CI 1.42-2.88). The lower risk of death was associated with the following factors: prescription of ACE inhibitors (ACEI) – HR 0.60 (95%CI 0.42-0.85); angiotensin II receptor blockers (ARB) – HR 0.26 (95%CI 0.13-0.50), beta-blockers – HR 0.71 (95%CI 0.50-0.99); statins – HR 0.59 (95%CI 0.42-0.82). Factors, listed above, had significant association not only with all-cause mortality but also with CV mortality and composite CV endpoint. The higher rate of hospitalizations due to CVD was associated with younger age (incidence rate ratio [IRR] for 1 year 1.03; 95%CI 1.02-1.05; р<0.001), female sex (IRR 2.40; 95%CI 1.79-3.23; р<0.001), COPD (IRR 2.44; 95%CI 1.63-3.65; р<0.001) and heart rate ≥80 beats/min (IRR 1.51; 95%CI 1.12-2.04; р=0.007).Conclusions. All-cause mortality in patients with a history of ACVA, enrolled in outpatient registry REGION, was 31.2% during 3-year follow-up. The proportion of CV death among the fatal cases was higher in the ACVA-FT registry than in ACVA-AR registry. The higher mortality rate was associated with the following factors: age, sex (male), recurrent ACVA, history of MI, diagnosis of AF, COPD and diabetes, low blood hemoglobin level, heart rate ≥80 beats/min, no antihypertensive therapy in arterial hypertension. The higher incidence of hospitalizations due to CVD was associated with younger age, sex (female), COPD and heart rate ≥80 beats/min. Prescription of ACEI, ARB, beta-blockers and statins was associated with lower risk of death and composite CV endpoint.
