Despite the growing incidence of acute kidney injury (AKI) worldwide, there is little data on the burden and outcomes of AKI in intensive care unit (ICU) in low resource settings. The present study assessed the incidence of AKI and its impact on mortality in ICU in Kinshasa (Democratic Republic of Congo). In a prospective cohort study, 476 consecutive critically ill patients (mean age 52 years, 57 % male) were screened for the presence of AKI in seven ICU from January 1st to March 30th, 2015. Serum creatinine was measured by the enzymatic method (Cobas C111 device®). AKI and its stages (no AKI, AKI 1, AKI 2 and AKI 3) were defined according to AKIN recommendations. The primary outcome was 28 days mortality. Survival (time-to death) curves were built using the Kaplan Meier methods. Predictors of mortality were assessed by Cox proportional hazards regression models. p < 0.05 defined the level of statistical significance. The cumulative incidence of AKI was 52.7 % with AKI stage 1, 2 and 3 in 23.7 %, 16.2 % and 12.8 % of patients, respectively. Among patients who developed AKI, 146 died (58 %) vs 62 patients (28 %) in the group without AKI. Only 6.5 % of the patients with AKI stage 3 benefited from dialysis. Median survival time was 15.0 days in patients without AKI and 3.0 days, 6.0 days and 8.0 days in patients with AKI stage 3, 2 and 1 (p < 0.001), respectively. In addition to respiratory distress-induced polypnea (HRa 1.60; 95 % CI: 1.08–2.37; p = 0.018), oxygen desaturation (HRa 1.53; 95 % CI: 1.13–2.08; p = 0.006) and multi-organic involvement (HRa 1.63; 95 % CI: 1.15–2.30), AKI emerged as an independent predictor of death (HRa 1.82; 95 % CI: 1.34–2.48; p < 0.001). More than half of critically ill patients in the present cohort developed AKI which contributed substantially to short-term mortality, highlighting the need for its prevention, early detection and management as well as the availability of dialysis in ICU.

Stroke is the third leading cause of cardiovascular mortality in dialysis patients. The objective of this study was to assess the extent of stroke in chronic hemodialysis patients. Historical cohort of patients enrolled in two hemodialysis (HD) centers from January 1, 2010 to December 31, 2011, including 191 patients (mean age 52 years, 68% men). Incidence curves and survival time analysis between the first day of HD and the end of the study were described by the Kaplan-Meier method. Independent stroke predictors were identified by multiple logistic regression analysis. P < 0.05 defined the level of statistical significance. 12 incident stroke were recorded during the study period, with 1622.1 person-months (PM), a stroke incidence rate of 7.4 cases per 1000 PM (95% CI = 7.35–7.44) at the point date. The incidence of stroke at 6 months, 12 months and 24 months was 9.8%, 11.9% and 13%, respectively. Only the absence of arterial hypertension (RR = 5.7, 95% CI: 1.52–21.42) emerged as an independent determinant of stroke. The high incidence of stroke in Kinshasa HD centers is partially explained by reverse epidemiology. Efforts must be made to understand this phenomenon in order to reduce its impact.

Background: ST-elevation myocardial infarction (STEMI) is a major public health problem. This study aimed to determine the prevalence and identify the determinants of STEMI-related complications in the Cardiology Intensive Care Unit of the Sud Francilien Hospital Center (SFHC). Methods: We retrospectively analyzed the data of 315 patients with STEMI aged ≥ 18 years. Logistic regression was used to identify factors independently associated with the occurrence of complications. Results: Overall, 315 patients aged 61.7 ± 13.4 years, of whom 261 were men, had STEMI during the study period. The hospital frequency of STEMI was 12.7%. Arrhythmias and acute heart failure were the main complications. Age ≥ 75 years (adjusted odds ratio [aOR], 5.18; 95% confidence interval [CI], 3.92–8.75), hypertension (aOR, 3.38; 95% CI, 1.68–5.82), and cigarette smoking (aOR, 3.52; 95% CI, 1.69–7.33) were independent determinants of acute heart failure. Meanwhile, diabetes mellitus (aOR, 1.74; 95% CI, 1.09–3.37), history of atrial fibrillation (aOR, 2.79; 95% CI, 1.66–4.76), history of stroke or transient ischemic attack (aOR, 1.99; 95% CI, 1.31–2.89), and low high-density lipoprotein-cholesterol (HDL-C) levels (aOR, 3.70; 95% CI, 1.08–6.64) were independent determinants of arrhythmias. Conclusion: STEMI is a frequent condition at SFHC and is often complicated by acute heart failure and arrhythmias. Patients aged ≥ 75 years, those with hypertension or diabetes mellitus, smokers, those with a history of atrial fibrillation or stroke, and those with low HDL-C levels require careful monitoring for the early diagnosis and management of these complications.

Despite the progress made in recent years in the treatment of Acute Heart Failure (AHF), its prognosis remains poor in the developing country. The objective of this study is to analyze the survival and predictors of mortality of patients with acute heart failure in the cardiology department of the Basse Terre Hospital Center in Guadeloupe. this was a historical cohort study carried out over a period from June 2021 to June 2022, targeting all acute heart failure patients undergoing cardiac monitoring in the cardiology department of the Basse Terre Hospital Center in Guadeloupe. Sociodemographic, clinical, biological characteristics and outcome (recovery or death) were studied. Survival was described using the Kaplan Meier method α = 5%. this study involved 242 acute heart failure patients whose median age was 75 years and the majority were male (sex ratio 2 M/1F). Among these patients, 14.9% died, the most common cause of death was cardiogenic shock (52.8%). After adjustment, tobacco consumption (aHR: 2.90; 95% CI: 1.36–8.09), Chronic Kidney Disease (aHR: 2.52; 95% CI: 1.22–5.20), infection (aHR: 2.14; 95CI %: 1.99–4.58), hyponatremia (aHR: 1.90; 95% CI: 1.10–2.86), mitral regurgitation (aHR: 3.04; 95% CI: 1.98–9.47) and N-terminal pro Brain Natriuretic Peptide > 10000ng/ml (aHR: 2.57; 95% CI: 1.21–5.49) were independently associated with the risk of death in heart failure patients. Acute heart failure leads to high mortality, mainly due to cardiogenic shock and factors of multiple organ failure.

Background: The coronavirus disease 2019 (COVID-19) pandemic is impacting the mental health of the population, but data on its impact in developing countries are lacking. The purpose of this study is to assess the psychological aspects of the COVID-19 pandemic in the population of Kinshasa. Methods: This cross-sectional and analytical study included 456 randomly selected respondents in the Ngafani district of the municipality of Selembao during the period from August 1 to October 30, 2020. Socio-demographic data, and data concerning COVID-19 and its impact on mental health, were studied. Anxiety and depression were studied using the Hospital Anxiety and Depression Scale (HADS). Results: The two genders were represented in equal proportions; the patients had a mean age of 40.4± 17.2 years with a high frequency of patients aged over 50 years. All had agreed to observe social distancing, but only 36.8% had accepted isolation. Using the HADS, 47.4% had a doubtful anxiety state and 23.7% had a definite anxiety state; 36.8% had a doubtful depressive state and 25% had a definite depressive state. Old age (≥ 50 years), female gender, lack of occupation, and isolation were independent determinants associated with anxiety and depression. Conclusion: The frequency of anxiety and depression during the COVID-19 pandemic was high. Older age, female gender, lack of a profession, and isolation were associated with anxiety and depression.

Background: In adolescents with Type 1 diabetes, lipid ratios are predictors of left ventricular diastolic dysfunction (LVDD). However, whether this also applies to adults with Type 2 Diabetes Mellitus (T2DM) is unclear. This study is aimed at assessing the correlations of serum lipid parameters and atherogenic indices with LVDD in patients with T2DM.Methods: This cross‐sectional study included 203 patients with T2DM aged 59.9 ± 13.6 years (111 males, sex ratio: 1 : 2 in favor of males) from eight randomly selected urban hospitals. Demographic information was collected, an anthropometric assessment was performed, and blood pressure was measured. Fasting blood samples were obtained to assess total cholesterol (TC), high‐density lipoprotein cholesterol (HDL‐C), low‐density lipoprotein cholesterol (LDL‐C), triglycerides (TGs), glucose, and glycated hemoglobin. The atherogenic index of plasma (AIP), Castelli Risk Index I (CRI‐I), Castelli Risk Index II (CRI‐II), atherogenic coefficient, and non‐HDL‐C were determined using specific formulas. Diastolic function was assessed using echocardiography as per the 2016 updated guidelines of the American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI).Results: Approximately 47.8% of the participants had LVDD. Compared with participants with normal diastolic function, those with LVDD were more likely to be older than 55 years (p < 0.001), tended to have obesity (p = 0.045), had a higher risk of developing dyslipidemia (p = 0.041), and higher AIP and CRI‐II (p < 0.05) levels while having similar low HDL‐C and hypertriglyceridemia frequencies. In the multivariate model adjusting for age, high AIP (adjusted odds ratio [aOR], 3.37; 95% confidence interval [CI], 1.22–5.34) and high CRI‐II (aOR: 3.80; 95% CI: 2.25–6.35) were independent determinants of LVDD.Conclusions: These results highlight the importance of considering atherogenic indices, primarily AIP and CRI‐II in the management of T2DM patients. High AIP and high CRI‐II could serve as surrogate markers of LVDD, an early cardiovascular manifestation in patients with T2DM.
