Poor Outcomes

Backgrounds: Small subcortical infarctions are caused by lipohyalinosis and also by microatheroma and microembolism. However, it remained still unknown which clinical or radiological findings could be useful for prediction of long-term prognosis. We sought to find whether perfusion images are associated with long-term poor clinical status. Methods: We reviewed 197 patients who admitted from January, 2009 to January, 2011, and who had the lacunae(≤20mm) in the perforator territory of the middle cerebral artery on diffusion-weight MRI(DWI) within 3 days of onset. T2 weighted imaging and perfusion-weighted MRI(PWI) were evaluated in all participants. We divided the patients according to the existence of perfusion defect and analyzed the association between perfusion defect and poor outcomes, defined as modified Rankin score(mRS)≥3 at 3 months Results: Among a total 197 patients(69 Men; 63.8±11.2y), 78 subjects(52 Men; 62.4±12.1y) had the perfusion defect on PWI. The subject with perfusion defect had the higher frequency of current smoker(P=0.03) and poor outcomes at 3 months (P=0.002), compared to those without. There was no difference in other risk factors, infarct size or parent artery stenosis between two groups. Multivariate binary regression analysis showed that the perfusion defect was strongly associated with poor outcomes at 3 months(P=0.002;adjusted OR 4.21; adjusted 95% CI,1.73-10.28). The propensity score regression analysis also indicated that perfusion defect could predict the poor prognosis(Propensity score adjusted OR,3.88). Conclusion: Perfusion defect of small vessel disease seems to have the influence on the recovery after lacunae. Further study may be needed to find whether the PWI can be useful for diagnosing the various etiology of lacunae.

Abstract OBJECTIVES Limited literature is available on the best management strategy for tricuspid valve (TV) disease in adults. We sought to review our long-term outcomes of TV surgery with regard to survival and reoperation. METHODS A retrospective analysis of all patients ≥18 years of age [n = 2541, aged 67 ± 13years, 1433 (56%) females] who underwent first-time TV surgery between January 1993 and December 2013 was done. There were 1735 patients who received TV repair and 806 patients underwent replacement. A gradient boosting machine model was used to derive a propensity score for predicting replacement using 27 preoperative characteristics. Four hundred and eighteen propensity-matched pairs of TV repair and replacement were identified. Cox proportional hazard regression was used on the matched subset to determine the effect of replacement. RESULTS Functional TV regurgitation was present in 54% (n = 1369). A bioprosthesis was used in 84% (n = 680) of replacements, while 54% (n = 934) of TV repairs were ring annuloplasties. Operative mortality was 8% (n = 212). Overall survival was 54%, 29% and 13% at 5, 10 and 15 years, respectively. After propensity score matching, replacement was significantly associated with increased mortality [hazard ratio (HR) 1.54, 95% confidence interval (CI) 1.18–2.00; P = 0.001]. The cumulative incidence of TV reoperation was similar between the 2 groups when accounting for the competing risk of death [Fine–Gray HR 1.56, 95% CI 0.9–2.8; P = 0.144]. CONCLUSIONS TV surgery is associated with poor outcomes due to multiple patient comorbidities. TV repair results in better survival compared to replacement in patients with similar comorbidities with no increased risk of getting a reoperation.

Background: Uncertainty exists over the long-term prognostic significance of cerebral small vessel disease (CSVD) in primary intracerebral hemorrhage (ICH).Methods: We performed a longitudinal analysis of CSVD and clinical outcomes in consecutive patients with primary ICH who had MRI. Baseline CSVD load (including white matter hyperintensities [WMH], cerebral microbleeds [CMBs], lacunes, and enlarged perivascular spaces [EPVS]) was evaluated. The cumulative CSVD score was calculated by combining the presence of each CSVD marker (range 0–4). We followed participants for poor functional outcome [modified Rankin scale [mRS] ≥ 4], stroke recurrence, and time-varying survival during a median follow-up of 4.9 [interquartile range [IQR] 3.1–6.0] years. Parsimonious and fuller multivariable logistic regression analysis and Cox-regression analysis were performed to estimate the association of CSVD markers, individually and collectively, with each outcome.Results: A total of 153 patients were included in the analyses. CMBs ≥ 10 [adjusted OR [adOR] 3.252, 95% CI 1.181–8.956, p = 0.023] and periventricular WMH (PWMH) (adOR 2.053, 95% CI 1.220–3.456, p = 0.007) were significantly associated with poor functional outcome. PWMH (adOR 2.908, 95% CI 1.230–6.878, p = 0.015) and lobar CMB severity (adOR 1.811, 95% CI 1.039–3.157, p = 0.036) were associated with stroke recurrence. The cumulative CSVD score was associated with poor functional outcome (adOR 1.460, 95% CI 1.017–2.096) and stroke recurrence (adOR 2.258, 95% CI 1.080–4.723). Death occurred in 36.1% (13/36) of patients with CMBs ≥ 10 compared with 18.8% (22/117) in those with CMB < 10 (adjusted HR 2.669, 95% CI 1.248–5.707, p = 0.011). In addition, the cumulative CSVD score ≥ 2 was associated with a decreased survival rate (adjusted HR 3.140, 95% CI 1.066–9.250, p = 0.038).Conclusions: Severe PWMH, CMB, or cumulative CSVD burden exert important influences on the long-term outcome of ICH.

Objective: Type 2 diabetes (T2D) is a risk factor for cognitive impairment and cerebral small vessel disease (CSVD). The relation of metformin use and cognitive impairment or CSVD is not clear. The objective of this study was to investigate the cross-sectional effects of long-term use of metformin on total CSVD burden and cognitive function in patients with T2D.Methods: A total of 234 participants with T2D from the memory clinic in Hebei General Hospital were enrolled in this retrospective study. Duration of metformin use and dosage were recorded. Along with cerebral magnetic resonance imaging (MRI) examination, Mini-Mental State Examination (MMSE) was also performed to assess their cognitive status. We determined the validated total CSVD score (ranging from 0–4) by combining four markers of CSVD that were visually rated. We used binary logistic regression analysis, ordinal logistic regression analysis and mediation analysis to assess the relation of long-term use of metformin with CSVD burden and cognitive function.Results: Binary logistic regression analysis showed long-term use of metformin was associated with reducing the risk of cognitive impairment (OR: 0.446; 95% Confidence Interval (CI): 0.249 to 0.800; P = 0.007), after adjustment of potential confounders, such as total CSVD burden score, age, HbA1c, hypertension, history of stroke, homocysteine, body mass index, TG and HDL-C. Ordinal logistic regression analysis suggested that long-term use of metformin was associated with alleviation of total CSVD burden score (OR: 0.583; 95% CI: 0.359 to 0.943; P = 0.027), after adjusting for age, HbA1c, hypertension, history of stroke, homocysteine, body mass index, TG and HDL-C. Mediation analysis showed significant mediation by the presence of severe CSVD burden score for long-term use of metformin in relation to cognitive impairment.Conclusion: Long-term use of metformin was associated with lower rates of cognitive impairment and lower total CSVD burden score in patients with T2D. A proportion of the relation between long-term use of metformin and cognitive impairment may be attributable to alleviation of CSVD burden.

Abstract Background The purpose of this study was to explore the effect of changing treatment to high-flux hemodialysis (HFHD) on mortality rate in patients with long-term low flux hemodialysis (LFHD). Methods The patients with end-stage renal disease (ESRD) who underwent LFHD with dialysis age more than 36 months and stable condition in our hospital before December 31, 2014 were included in this study. They were divided into control group and observation group. Propensity score matched method was used to select patients in the control group. The hemodialysis was performed 3 times a week for 4 h. The deadline for follow-up is December 31, 2018. End-point event is all-cause death. The survival rates of the two groups were compared and multivariate Cox regression analysis was carried out. Results K-M survival analysis showed that the 1-year, 2-year, 3-year and 4-year survival rates of HFHD group were 98, 96, 96 and 96%, respectively. The 1-year, 2-year, 3-year and 4-year survival rates of LFHD group were 95, 85, 80 and 78%, respectively. Log-rank test showed that the survival rate of HFHD group was significantly higher than that of LFHD group (x2= 7.278, P = 0.007). Multivariate Cox regression analysis showed that male, age, hemoglobin and low-throughput dialysis were independent predictors of death (P < 0.05). Compared with LFHD, HFHD can significantly reduce the mortality risk ratio of patients, as high as 86%. Conclusion The prognosis of patients with ESRD who performed long-term LFHD can be significantly improved after changing to HFHD.

The Impact

Background: The novel pandemic of Coronavirus disease 2019 (COVID-19) has becoming a public health issue since March 2020 considering that more than 30 million people were found to be infected worldwide. Particularly, recent evidences suggested that men may be considered as at higher risk of poor prognosis or death once the infection occurred and concerns surfaced in regard of the risk of a possible testicular injury due to SARS-CoV-2 infection. Results: Several data support the existence of a bivalent role of testosterone (T) in driving poor prognosis in patients with COVID-19. On one hand, this is attributable to the fact that T may facilitate SARS-CoV-2 entry in human cells by means of an enhanced expression of transmembrane serine-protease 2 (TMPRSS2) and angiotensin-converting enzyme 2 (ACE2). At the same time, younger man with normal testicular function compared to women of similar age are prone to develop a blunted immune response against SARS-CoV-2, being exposed to less viral clearance and more viral shedding and systemic spread of the disease. Conversely, low levels of serum T observed in hypogonadal men predispose them to a greater background systemic inflammation, cardiovascular and metabolic diseases, and immune system dysfunction, hence driving harmful consequences once SARS-CoV-2 infection occurred. Finally, SARS-CoV-2, as a systemic disease, may also affect testicles with possible concerns for current and future testicular efficiency. Preliminary data suggested that SARS-CoV-2 genome is not normally found in gonads and gametes, therefore sex transmission could be excluded as a possible way to spread the COVID-19. Conclusion: Most data support a role of T as a bivalent risk factor for poor prognosis (high/normal in younger; lower in elderly) in COVID-19. However, the impact of medical treatment aimed to modify T homeostasis for improving the prognosis of affected patients is unknown in this clinical setting. In addition, testicular damage may be a harmful consequence of the infection even in case it occurred asymptomatically but no long-term evidences are currently available to confirm and quantify this phenomenon. Different authors excluded the presence of SARS-CoV-2 in sperm and oocytes, thus limiting worries about both a potential sexual and gamete-to-embryos transmission of COVID-19. Despite these evidence, long-term and well-designed studies are needed to clarify these issues.
