Etiologies and factors associated with mortality in patients with non-traumatic coma in a tertiary hospital in Bukavu, eastern Democratic Republic of the Congo. Heliyon 2023; 9:e18398. [PMID: 37520991 PMCID: PMC10382283 DOI: 10.1016/j.heliyon.2023.e18398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 07/12/2023] [Accepted: 07/17/2023] [Indexed: 08/01/2023] Open
Abstract
Non-traumatic coma (NTC) is a common medical condition often associated with poor outcomes. Identifying underlying causes is crucial for effective management and prognostication, particularly in resource-poor settings. This study aimed to identify the most common causes and prognostic factors of NTC in a tertiary hospital in Bukavu, in the eastern Democratic Republic of the Congo (DRC), using the Glasgow Coma Scale (GCS) as well as other simple and affordable clinical and paraclinical tools. This retrospective observational study included 219 consecutive patients admitted to the intensive care unit of the Provincial General Hospital of Bukavu between January 2016 and December 2018. Sociodemographic, clinical, and laboratory data were also collected. Bivariate and multivariate analyses were performed to identify different causes and factors associated with poor outcomes in these patients. The median age of the patients was 49 (interquartile range [IQR]: 33-61) years, and they were predominantly men (62.8%). The most common causes of NTC were stroke (25.7%), acute metabolic complications of diabetes (21.9%), and primary brain infections (meningoencephalitis, 16.0%; and cerebral malaria, 14.2%). The NTC-related in-hospital mortality rate was 35.2%. A high mortality was significantly and independently associated with a GCS<7 (adjusted odds ratio [OR]: 4.30, 95% confidence interval [CI]: 1.73-10.71), the presence of meningismus at clinical evaluation (adjusted odds ratio [aOR] 3.86, 95%CI: 1.41-10.55), oxygen saturation <90% (aOR 3.99, 95%CI: 1.71-9.28), the consumption of traditional herbal medicines prior to hospital admission (aOR 2.82, 95%CI: 1.16-6.86), and elevated serum creatinine (aOR 1.64, 95%CI: 1.17-2.29). In conclusion, clinical neurological examinations, along with simple and affordable paraclinical investigations, can provide sufficient information to determine the etiology of NTC and evaluate the prognosis of comatose patients, even in resource-poor settings. Physicians may use the GCS as a simple, reliable, and affordable tool to identify patients who require special attention and care.

Abstract
BACKGROUND Stroke mortality and related functional disability have been declining over the last two decades, but stroke continues to represent the second leading cause of cardiovascular death worldwide and the number one cause for acquired long-term disability. OBJECTIVES Assess short- and long-term health outcomes after acute ischemic stroke and analyze factors associated with poor survival and functional outcomes. DESIGN Retrospective and survival analysis SETTING: Inpatient unit at a tertiary care referral hospital. PATIENTS AND METHODS All patients admitted with acute ischemic stroke from 1 January 2017 to 31 August 2018 were included in the study. Functional status was assessed using the modified Rankin Scale (mRS). Other demographic and clinical variables were obtained from medical records. Data were analyzed by multivariable logistic regression, Cox proportional hazards, and the Kaplan-Meier method. Long-term follow-up data, including mortality and mRS was collected by follow-up phone call. MAIN OUTCOME MEASURES Functional dependency and factors associated with mortality. SAMPLE SIZE AND CHARACTERISTICS 110 with mean age of 67.0 (14.7) years; 59 patients (53.6%) were males. RESULTS Hypertension (75.5%), diabetes mellitus (54.6%), and dyslipidemia (29.1%) were common. Sixty-five patients (59.1%) had mRS >2 upon discharge including 18 patients (16.4%) who died during the hospital stay. The cumulative mortality rate was 25.4% (28/110) at 12 months and 30.0% (33/110) at 24 months. Twenty-nine stroke survivors (29/70, 41.4%) remained physically dependent (mRS >2) at the end of follow-up. Old age, atrial fibrillation, history of prior stroke, chronic kidney disease, and peripheral arterial disease were associated with increased mortality and functional dependence. CONCLUSIONS Patients in Oman with acute ischemic stroke tend to have a high comorbidity burden, and their functional dependency and mortality are higher compared to patients from developed countries. Therefore, evidence-based measures such as establishing stroke units are essential to improve the health outcomes of patients with acute ischemic stroke. LIMITATIONS Retrospective at single center. CONFLICT OF INTEREST None.

Magnitude and Predictors of In-Hospital Stroke Mortality in Ethiopia: A Systematic Review and Meta-Analysis. Stroke Res Treat 2022; 2022:7202657. [PMID: 35656388 PMCID: PMC9155958 DOI: 10.1155/2022/7202657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 04/02/2022] [Accepted: 05/06/2022] [Indexed: 11/17/2022] Open
Abstract
Introduction Stroke is the second leading cause of mortality worldwide, accounting for approximately 5.5 million deaths each year. Due to demographic and health changes, the epidemiology of stroke is shifting from industrialized to low- and middle-income nations. Ethiopia is a developing country with a population that reflects this shift. Therefore, this systematic review and meta-analysis are aimed at evaluating the extent of in-hospital mortality of both ischemic and hemorrhagic stroke in Ethiopia and determining relevant factors associated with the mortality. Methods Observational studies published as of July 15, 2020, that reported the magnitude, predictors, and causes of in-hospital mortality of stroke were systematically and comprehensively retrieved using the PRISMA 2020 criteria from databases such as PubMed/MEDLINE, Science Direct, and Google Scholar. The review papers were chosen based on the study methodology (facility-based observational), the study area (Ethiopia), the study population (adult patients with stroke), the outcome (in-hospital mortality), and the fact that they were published in English. Result A total of 3709 patients with stroke were included in this systematic review and meta-analysis, which included 19 publications. In-hospital mortality was 14.03 percent on average in the studies, with reports ranging from 6.04 percent to 37.37 percent. Patients with hemorrhagic type stroke, admission Glasgow Coma Scale less than or equal to 12, impaired mental status, National Institutes of Health Stroke Scale stroke level greater than 13, prolonged hospital stay, any incontinence, pneumonia, and/or swallowing trouble had an increased risk of death after stroke. Conclusion The magnitude of in-hospital mortality of patients with stroke in Ethiopia is high. The assessment of the level of consciousness is vital for clinical management and as an indicator of prognosis. Patients with unfavorable prognostic signs, such as entry Glasgow Coma Scale, National Institutes of Health Stroke Scale stroke level > 13, hemorrhagic stroke, pneumonia, incontinence, and dysphagia, should be given priority.

Abstract
(1) Background: Dysphagia is common in acute stroke patients and is a major risk factor for aspiration pneumonia. We investigated whether the early detection of dysphagia in stroke patients through screening could prevent the development of pneumonia and reduce mortality; (2) Methods: We searched the PubMed, Embase, Cochrane Library, and Scopus databases for relevant studies published up to November 2021. We included studies that performed dysphagia screening in acute stroke patients and evaluated whether it could prevent pneumonia and reduce mortality rates. The methodological quality of individual studies was evaluated using the Risk Of Bias In Non-randomized Studies of Interventions tool, and publication bias was evaluated by the funnel plot and Egger’s test; (3) Results: Of the 6593 identified studies, six studies met the inclusion criteria for analysis. The screening group had a significantly lower incidence of pneumonia than the nonscreening group did (odds ratio (OR), 0.60; 95% confidence interval (CI), 0.42 to 0.84; p = 0.003; I2, 66%). There was no significant difference in mortality rate between the two groups (OR, 0.61; 95% CI, 0.33 to 1.13; p = 0.11; I2, 93%); (4) Conclusions: Early screening for dysphagia in acute stroke patients can prevent the development of pneumonia.

Abstract
Background Despite the fact that stroke has been reported as one of the top three leading causes of death and morbidity in Ethiopia, there are limited data regarding the management of stroke and clinical outcomes. Hence, the present study aimed to evaluate the pharmacotherapy of stroke and factors associated with poor treatment outcomes. Methods A retrospective cross-sectional study was conducted at Jimma University Medical Center (JUMC) among adult stroke patients managed from 2014 to 2017. Clinical characteristics, treatment, and outcomes data were analyzed by using SPSS version 21. Multivariable logistic regression was performed to identify the predictors of poor treatment outcomes. Two-sided P < 0.05 was accepted as statistically significant. Results A total of 153 illegible patient cases were included in this study. The majority, 111 (72.5%), were male and the mean age of the patients was 57±13.7 years. Among 153 stroke patients, 112 (73.2%) patients presented with ischemic stroke. Aspirin and statins (78.6%) were the most commonly used treatment among ischemic stroke patients, whereas enalapril was used in about (43%) of stroke patients to treat high blood pressure. About 61 (40%) stroke patients had poor treatment outcomes; of this, 36 (23.5%) died in hospital. Older age (AOR = 1.034; 95% CI: 1.003–1.069), history of heart failure (AOR = 4.26; 95% CI: 1.58–11.48), loss of consciousness diabetes (AOR = 3.05 95% CI: 1.25–7.44), and aspiration pneumonia (AOR = 5.94; 95% CI: 2.46–14.32) were significantly associated with poor treatment outcomes. Conclusion Overall, treatment of stroke patients was sub-optimal and almost half of the patients had poor treatment outcomes. Availing of thrombolytic therapy, devising appropriate preventive measures of risk factors (hypertension), and decreasing preventable complication such as aspiration pneumonia could improve patient outcomes.

Abstract
PURPOSE This study aims to estimate the computed tomography (CT) and Magnetic resonance imaging (MRI) uptake, stroke subtypes and 30-days case-fatality in Nigeria. METHODS Stroke diagnosis and mortality data were identified from relevant databases. A random effect meta-analysis was conducted to obtain the pooled percentage uptake of CT/MRI, including 30-days case fatality and a meta-regression-like epidemiological model was applied on all data points. FINDINGS A total of 24 studies involving 5874 stroke patients conducted in predominantly tertiary referral hospitals met the inclusion criteria. The pooled CT/MRI uptake in the last seven years was 46.66% (95% CI = 15.35 to 77.98, 8 studies). There were significant variations in the prevalence of stroke subtypes. The pooled prevalence ischemic stroke was highest (55.32%, 95% CI 48.67 to 61.97, 16 studies), followed by intracerebral haemorrhage (ICH) (32.69%, 95% CI 25.54 to 39.83, 16 studies), subarachnoid haemorrhage (SAH) (3.76%, 95% CI 2.30 to 5.22, 14 studies). In addition, the stroke of undetermined aetiology was found to be 16.57% (95% CI, 7.44-25.70, 8 studies). Overall, the 24-h, one-week and 30-days case-fatality from stroke were 10.84% (95% CI, 4.48-17.20), 24.62% (95% CI, 17.20-32.04) and 33.28% (95% CI, 27.80-38.77), respectively. There was a moderate negative correlation between prevalence of brain imaging uptake and ischaemic stroke, albeit not statistically significant (Spearman rho = 0.333, p-value = .412). CONCLUSION Uptake of CT/MRI procedure for stroke is poor in Nigeria. Although poverty, inaccessibility and influence of major risk factors remain pronounced, scaling up of effective strategies for stroke prevention and management should be a major public health policy priority in Nigeria.

Abstract
AIMS AND OBJECTIVES To explore the characteristics of mortality among severe stroke patients, analyse their causes of death and provide evidence for improving the survival rate of stroke patients. BACKGROUND Stroke is an important fatal and disabling disease that poses a large burden on its patients, and its high death rates have caused substantial concern to the World Health Organization. DESIGN A retrospective case-control study. METHODS A total of 188 patients who died of stroke in the neurological intensive care unit of the First Affiliated Hospital of Chongqing Medical University from January 2012-December 2015 were selected as cases. Additionally, 188 stroke survivors from the same neurological intensive care unit were randomly selected as paired cases. The clinical characteristics of the severe stroke patient deaths were analysed, and a univariate analysis was conducted to determine potential mortality risk factors. A logistic regression analysis was then conducted to determine the independent risk factors of mortality. RESULTS We investigated a total of 231 cases of death in neurological intensive care unit patients, 188 of whom died of stroke. Therefore, the death rate from stroke accounted for 81.3% of the total population, with ischaemic, haemorrhagic and mixed strokes accounting for 47.19%, 26.84% and 7.36% of the patients, respectively. The leading cause of death was central nervous system-related causes (central respiratory and circulatory failure, brain herniation), followed by multisystemic causes. The independent risk factors of death among the neurological intensive care unit patients were as follows: brain herniation (OR = 18.15), multiple organ failure (OR = 13.12), dyslipidemia (OR = 4.64), community-acquired lung infection (OR = 4.15), use of mechanical ventilation (OR = 3.37), hypoproteinemia (OR = 2.29), history of hypertension (OR = 2.03) and hospital-acquired pneumonia (OR = 1.75). CONCLUSIONS The most common cause of death in stroke patients was damage to the central nervous system. Independent risk factors were brain herniation, multiple organ failure, dyslipidemia, community-acquired lung infection, the use of mechanical ventilation, hypoproteinemia, a history of hypertension and hospital-acquired pneumonia. Clinicians should be aware of the presence and possible effects of these conditions. Early prevention, monitoring and intervention to modify controllable risk factors will improve patient prognosis. RELEVANCE TO CLINICAL PRACTICE Clinicians should be aware of the multiple independent risk factors of death and implement timely treatment measures to reduce the incidence of death in severe stroke patients.

Abstract
BACKGROUND AND PURPOSE Ischemic stroke causes death and disability worldwide. Better understanding and controlling factors associated will improve the prevention of the disease. This study reviews records of patients with ischemic stroke in Central Africa. MATERIAL AND METHODS Patients of Bantu ethnicity with clinical diagnosis of stroke and lesion on computed tomography scan from January 2011 to December 2012 were selected. Computed tomographic subtypes of ischemic stroke and factors associated were considered with tropical seasonal variation. RESULTS Of the 303 first-ever stroke patients (average age 53 years old, range 3- 84 years old; 62% male) were included in the study. The prevalence of computed tomography stroke subtypes was: lacunar infarct (63%) and non lacunar infarct lesion (37%). Silent brain infarct was seen in 9 % of patients. Prevalence of factors associated with ischemic stroke was: age≥60 years old (55%); male gender (63%), chronic and uncontrolled hypertension (54%) and type 2 Diabetes mellitus (11%). A seasonal high prevalence was observed in warmer season (p < 0.05). CONCLUSIONS This study shows a high prevalence of lacunar infarct than non lacunar in Bantu of Central Africa.

Abstract
BACKGROUND Stroke causes death and disability worldwide. Hypertension is the most prevalent risk factor. In Nigeria, studies on outcome and risk factors of stroke are from urban-based hospitals. This study aims to look at stroke outcome and the major modifiable risk factors of hospitalized stroke patients in semi-urban Nigeria. METHODS The medical records of stroke patients admitted between March 2008 and February 2010 were reviewed retrospectively. The relevant demographic, clinical and laboratory data of each patient were retrieved. RESULTS A total of 99 cases of stroke made up of 51 males and 48 females were reviewed. Mean age of the subjects was 66.22 ± 12.67 years. Mean systolic blood pressure and diastolic blood pressure at presentation were 171.41 ± 39.10 mmHg and 100.44 ± 21 mmHg, respectively. About 61.6% were known hypertensives, while 31.3%, not previously known to be hypertensive, had SBP ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Overall, 85.9% of the subjects had SBP ≥ 140 mmHg and/or DBP ≥ 90 mmHg. In all, 46.5% had SBP ≥ 180 mmHg, and 63% of this number had SBP ≥ 200 mmHg; 42.4% had DBP ≥ 110 mmHg. Other major risk factors were hypercholesterolaemia (34.4%), diabetes mellitus (16.6%), previous cerebrovascular accident (15.2%) and smoking (9.4%). In all, 31.3% had two or more modifiable stroke risk factors. 36.4% of the subjects were comatose. Overall case fatality rate was 45.8%, 75% of the subjects with coma died, compared to 27.6% without coma (p < 0.01). CONCLUSION Mortality in our stroke patients is high. Hypertension is the commonest modifiable risk factor, and the presence of coma at presentation is associated with poor prognosis.
