Abstract
The metabolic syndrome (MetS) is a cluster of cardiovascular risk factors including insulin resistance (IR), dyslipidemia, and hypertension, which may also foster development of chronic kidney disease. The mechanisms of MetS-induced kidney disease are not fully understood. The purpose of this review is to summarize recent discoveries regarding the impact of MetS on the kidney, particularly on the renal microvasculature and cellular mitochondria. Fundamental manifestations of MetS include IR and adipose tissue expansion, the latter promoting chronic inflammation and oxidative stress that exacerbate IR. Those in turn can elicit various kidney injurious events through endothelial dysfunction, activation of the renin-angiotensin-aldosterone system, and adipokine imbalance. Inflammation and IR are also major contributors to microvascular remodeling and podocyte injury. Hence, these events may result in hypertension, albuminuria, and parenchymal damage. In addition, dyslipidemia and excessive nutrient availability may impair mitochondrial function and thereby promote progression of kidney cell damage. Elucidation of the link between MetS and kidney injury may help develop preventative measures and possibly novel therapeutic targets to alleviate and avert development of renal manifestations.

Abstract
The life expectancy of patients with schizophrenia (SCH) is 11 to 20 years less than the general population. There is an association between SCH and various diseases and chronic conditions, highlighting the cardio-metabolic diseases. This association has been attributed to the use of antipsychotics, however, evidence has also shown intrinsic susceptibility of schizophrenic patients the development of chronic conditions. This review aims to update knowledge about chronic conditions such as cardiometabolic risk and sleep, bone and kidney disorders related to SCH. These patients have a high prevalence of risk behaviors, including smoking and poor diet. They have a worse metabolic profile than the general population and a greater likelihood of developing metabolic syndrome, diabetes and cardiovascular disease. SCH has also been associated with other chronic diseases such as osteoporosis and chronic kidney disease. The high prevalence of these comorbidities in schizophrenic population is not explained solely by the antipsychotic treatment, therefore intrinsic mechanisms associated to SCH are postulated to be associated with these conditions. This new information requires a change in the multidisciplinary medical approach for the study and management of schizophrenic patients.

Abstract
Crystal arthropathies are among the most common causes of painful inflammatory arthritis. Gout, the most common example, has been associated with cardiovascular and renal disease. In recent years, evidence for these associations and those involving other comorbidities, such as the metabolic syndrome, have emerged, and the importance of asymptomatic hyperuricemia has been established. In this review, an update on evidence, both experimental and clinical, is presented, and associations between hyperuricemia, gout, and several comorbidities are described. Causality regarding calcium pyrophosphate arthropathy and associated comorbidities is also reviewed.
