Correlating Autonomic Nervous System Aging and Cognitive Impairment

Heart rate variability is known to be a good way to assess the function of the autonomic nervous system. (That said, most of the commercially available tools for those who want to measure heart rate variability at home are quite unreliable; it is challenging for a self-experimenter to obtain results that are as useful as those provided by medical equipment used by medical staff). The autonomic nervous system, like all aspects of our biology, is negatively impacted by the progression of aging. The same mechanisms of molecular damage that drive autonomic nervous system aging will be involved in cognitive decline and neurodegenerative conditions, so it should be no great surprise to see that these forms of age-related degeneration correlate with one another. Changes in cognitive performances and cardiovascular disorders represent a normal phenomenon of the aging process. Cardiovascular risk factors, such as smoking, obesity, diabetes mellitus, increased cholesterol, and systemic blood pressure (BP) levels, and an inadequate lifestyle may compromise also cerebral blood flow, which in turn can negatively affect cognitive performance. Moreover, the same age-related anatomical and functional cardiac changes, including also the autonomic nervous system (ANS), determine cardiac output alteration, causing cerebral blood flow modulation. This variation could interfere with microcirculation and cause cerebral ischemia, particularly in those brain sites that control the different...

Authors: Kleinaki Z, Kapnisi S, Theodorelou-Charitou SA, Nikas IP, Paschou SA Abstract Diabetes mellitus (DM) is a chronic multisystem disease. Diabetic nephropathy (DN) is one of its significant microvascular complications, associated with increased morbidity and mortality. The aim of this article is to review the literature regarding the latest advances in the management of type 2 DM (T2DM) in patients with chronic kidney disease (CKD). We initially refer to the screening guidelines, the diagnostic tests used, the need for novel biomarkers in DN, the recent advances in high-risk patient identification, the recomm...

Background: Brachial plexus birth injury (BPBI) is a condition in which the brachial plexus is thought to be damaged during the birth process. Studies have cited a varying incidence rate ranging from 0.5 to 4.0 per 1000 live births. The purpose of this study is to evaluate birth claims data over a 15-year period to identify risk and protective factors for BPBI in the state of Colorado. Methods: A data request was made to the state hospital association for birth claims data. We requested all birth claims from the years 2000 to 2014. ICD9 codes for variables of interest included: BPBI, shoulder dystocia, heavy-for-dates...

Conclusion. The spontaneous incidence rate of vertebral body infection among OVF patients was 0.7%; however, the occurrence of this complication led to serious events. Clinicians should pay attention to the possibility of bacillemia in elderly or immunocompromised OVF patients. Level of Evidence: 4

Conclusion. Although intent-to-treat analysis failed to show significant differences in patients treated surgically, results of the as-treated analysis determined statically greater improvements in those patients with spondylolisthesis who were treated surgically as compared to those treated nonoperatively. Level of Evidence: 2

Conclusion. Ten years after its inception, SPORT has made strides in standardization and optimization of treatment for spinal pathologies. SPORT has provided clinicians with insight about outcomes of surgical and nonoperative treatment of spinal stenosis. Results showed significantly greater improvement through 4 year follow up in those patients that received surgical treatment, however the difference between the surgical and nonsurgical groups diminished at 8 year follow up. Level of Evidence: 3

This study is par for the course, looking at Japanese Olympic participants. Interestingly, it hints at the upper end of the dose-response curve for physical activity, in that a longer career as a professional athlete may be detrimental in comparison to lesser degrees of exercise and training. From this large, retrospective cohort study targeting 3546 Japanese Olympic athletes, we observed significant lower mortality among Olympians compared with the Japanese general population. The overall standardised mortality ratio (SMR) was 0.29. The results were consistent with previous studies conducted in other non-Asian co...

Conclusion: This study observed an inverse correlation between plasma LDL cholesterol and heart function in individuals with T2DM. Patients with higher levels of plasma LDL cholesterol had worse left ventricular function. Therefore, plasma LDL cholesterol may be a modifiable risk factor of heart failure in diabetes, but prospective studies are necessary to confirm this finding. Introduction Type 2 diabetes mellitus (T2DM) is a metabolic disease that affects a considerable number of patients worldwide (1). Among diabetic individuals, cardiovascular disease (CVD) is the leading cause of morbidity and mortality (2). C...

Conclusions Aging leads to a progressive decrease in androgen production that, in turn, leads to the development of LOH, defined by significant low T serum levels (in the lowest quartile) in the presence of signs and symptoms of hypogonadism (51). LOH could be due to both testicular and hypothalamic-pituitary dysfunction (32), and ED is one of its main symptoms. ED in LOH is linked to increased oxidative stress, subclinical inflammation, and subsequent endothelial dysfunction (101). In elderly men, it has been shown that LOH is also linked to lower cAMP pool and to an alteration of the cGMP signaling pathway. PDE5 gene l...

Authors: Vujnic M, Peric S, Calic Z, Benovic N, Nisic T, Pesovic J, Savic-Pavicevic D, Rakocevic-Stojanovic V Abstract Objectives: metabolic syndrome (MetS) increases risk of cardiovascular diseases and diabetes mellitus type 2. Aim of this study was to investigate frequency and features of MetS in a large cohort of patients with DM2. Materials &methods: this cross-sectional study included 47 DM2 patients. Patients were matched with 94 healthy controls (HCs) for gender and age. MetS was diagnosed according to the new worldwide consensus criteria from 2009. Results: mean age of DM2 patients was 52 &plusm...

Conclusion The relationships between the potency of 5-HT2C blockade and hypertriglyceridemia and the potency of M3 blockade and glucose intolerance were shown in clinical setting. Receptor-binging profiles might be useful to estimate metabolic effect of antipsychotics-treatment. References Meyer JM, Davis VG, Goff DC, et al.
