The objective of this study is to scrutinize the frequency of anemia in chronic psychiatric patients and the clinical and sociodemographic factors that could affect this frequency.Methods: All inpatients in our clinic who satisfied the study criteria and received treatment between April 2014 and April 2015 were included in this cross-sectional study. Sociodemographic data for 378 patients included in the study and hemoglobin (Hb) and hematocrit values observed during their admission to the hospital were recorded in the forms. Male patients with an Hb level of <13 g/dL and nonpregnant female patients with an Hb level of <12 g/dL were considered as anemic.Findings: Axis 1 diagnoses demonstrated that 172 patients had depressive disorder, 51 patients had bipolar disorder, 54 patients had psychotic disorder, 33 patients had conversion disorder, 19 patients had obsessive-compulsive disorder, 25 patients had generalized anxiety disorder, and 24 patients had other psychiatric conditions. It was also determined that 25.4% of the patients suffered from anemia. Thirty-five percent of females and 10% of males were considered as anemic. The frequency of anemia was the highest among psychotic disorder patients (35%), followed by generalized anxiety disorder patients (32%), and obsessive-compulsive disorder patients (26%). Anemia was diagnosed in 22% of depressive disorder patients, 25% of bipolar disorder patients, and 24% of conversion disorder patients.Results: The prevalence of anemia among chronic psychiatry patients is more frequent than the general population. Thus, the study concluded that it would be beneficial to consider the physical symptoms and to conduct the required examinations to determine anemia among this patient group.

Hypothalamic Energy Regulatory Peptides in Chronic Kidney Disease
Loss of appetite affects one-third of patients with CKD and is the leading cause of malnutrition in this population. Orexigenic Agouti-related peptide (AgRP) with neuropeptide-Y (NPY) and anorexigenic melanocyte-stimulating hormone-α (MSH-α) with cocaine- and amphetamine-regulated transcript (CART) are known to regulate appetite. In this study, we aimed to evaluate the levels of these peptides in CKD patients compared to healthy subjects and demonstrate the effects of dialysis treatment and erythropoiesis-stimulating agent (ESA) therapy. The cross-sectional study is composed of consecutive inclusion of 20 healthy individuals, 20 predialysis CKD patients, 20 HD, and 20 peritoneal dialysis (PD) patients. Exclusion criteria were an active infection, history of malignancy, hypo- or hyperthyroidism, and diabetes. Patients on dialysis had targeted Kt/Vs. Demographic features and BMIs of the four groups were similar. Levels of AgRP, NPY, AMSH, and CART were significantly different between groups. Nondialysis CKD patients had significantly lower hypothalamic hormones compared to healthy individuals, HD and PD patients (P = 0.02, P = 0.03, and P = 0.07 for AgRP; P = 0.02, P = 0.01, and P = 0.09 for NPY; P = 0.02, P = 0.02, and P = 0.03 for AMSH; P = 0.02, P = 0.005, and P = 0.030 for CART). Dialysis patients with or without ESA treatment had similar hormone levels (P = 0.13 for AgRP; P = 0.11 for NPY; P = 0.23 for AMSH, and P = 019 for CART). Predialysis CKD patients have lower orexigenic and presumably indirectly lower anorexigenic peptides compared to healthy subjects and dialysis patients. ESA treatment does not affect these hypothalamic peptides in dialysis patients

Effects of caloric restriction and aerobic exercise on circulating cell-free mitochondrial DNA in patients with moderate to severe chronic kidney disease.
Circulating cell-free mitochondrial DNA (ccf-mtDNA) may induce systemic inflammation, a common condition in chronic kidney disease (CKD), by acting as a damage-associated molecular pattern. We hypothesized that in patients with moderate to severe CKD, aerobic exercise would reduce ccf-mtDNA levels. We performed a post hoc analysis of a multicenter randomized trial (NCT01150851) measuring plasma concentrations of ccf-mtDNA at baseline and 2 and 4 mo after aerobic exercise and caloric restriction. A total of 99 participants had baseline ccf-mtDNA, and 92 participants completed the study. The median age of the participants was 57 yr, 44% were female and 55% were male, 23% had diabetes, and 92% had hypertension. After adjusting for demographics, blood pressure, body mass index, diabetes, and estimated glomerular filtration rate, median ccf-mtDNA concentrations at baseline, 2 mo, and 4 mo were 3.62, 3.08, and 2.78 pM for the usual activity group and 2.01, 2.20, and 2.67 pM for the aerobic exercise group, respectively. A 16.1% greater increase per month in ccf-mtDNA was seen in aerobic exercise versus usual activity (P = 0.024), which was more pronounced with the combination of aerobic exercise and caloric restriction (29.5% greater increase per month). After 4 mo of intervention, ccf-mtDNA increased in the aerobic exercise group by 81.6% (95% confidence interval: 8.2-204.8, P = 0.024) compared with the usual activity group and was more marked in the aerobic exercise and caloric restriction group (181.7% increase, 95% confidence interval: 41.1-462.2, P = 0.003). There was no statistically significant correlation between markers of oxidative stress and inflammation with ccf-mtDNA. Our data indicate that aerobic exercise increased ccf-mtDNA levels in patients with moderate to severe CKD.NEW & NOTEWORTHY The effects of prolonged exercise on circulating cell-free mitochondrial DNA (ccf-mtDNA) have not been explored in patients with chronic kidney disease (CKD). We showed that 4-mo aerobic exercise is associated with an increase in plasma ccf-mtDNA levels in patients with stages 3 or 4 CKD. These changes were not associated with markers of systemic inflammation. Future studies should determine the mechanisms by which healthy lifestyle interventions influence biomarkers of inflammation and oxidative stress in patients with CKD
