Fibromyalgia (FM) is a chronic pain syndrome characterized by widespread, persistent pain that lasts more than three months without an evident organic lesion. FM has been considered controversial throughout history due to its validity as a diagnosis being constantly in question. Most patients diagnosed with FM are females. FM has been associated with multiple conditions, including irritable bowel and psychiatric disorders. Among all associated conditions, depression has been frequently found in patients with FM. Studies suggest that depression negatively affects the outcome of patients with FM. Moreover, a bidirectional relation between FM and depression has been depicted: depression increases the risk of FM being diagnosed later in life, as well as FM increases the risk of developing depression. In this article, we discussed aspects that FM and depression share and that might link both diseases, such as certain elements they seem to share in their pathophysiology: predisposing and triggering factors, central sensitization and kindling, areas of the brain implicated in both pain modulation and mood regulation, and hypothalamic-pituitary-adrenal axis (HPA axis) alterations. In addition, we highlighted the prevalence of depression in patients with FM, overlapping symptoms between FM and depression and how to assess them, and treatment strategies that have shown effective management of both conditions when concomitant. Due to the improvement of many aspects of FM when depression is appropriately targeted, screening for depression in patients with FM, despite its difficulty, has been encouraged.

Comorbid diabetes and depression are a significant public health burden as the consequences of both diseases are worsened by each other. In this study, we have compiled and analyzed findings from various studies to demonstrate that diabetes has a strong association with depression. Both have a significant impact on the quality of life, although the exact mechanisms through which these two chronic diseases affect each other remain unknown. This article discussed the shared etiological factors of comorbidity between diabetes and depression, including physiological (e.g., deregulation of the hypothalamic-pituitaryadrenal (HPA) axis, sympathetic nervous system (SNS) overactivity, microvascular dysfunction, arterial stiffening, inflammation, and cytokines), behavioral (e.g., diet and lifestyle modifications), and environmental (e.g., childhood adversity, poverty, and neighborhood environment). Included data from a range of settings have suggested that the prognosis of both diabetes and depression, in terms of complications, treatment efficacy, morbidity, and mortality, is worse for either disease when they occur concurrently than individually. The implication for the physical, mental, and social well-being of depression in diabetes causes poor self-care and adherence to medical treatment. This article also highlights the importance of regular screening and prompts the treatment of comorbid diabetes and depression with pharmacotherapy, face-to-face psychotherapy, and non-face-to-face models of alternative psychological interventions, including information and communication technologies (ICTs), computer-based diabetes selfmanagement interventions, and digital mental health intervention, to improve the outcomes of both diseases.Categories: Endocrinology/Diabetes/Metabolism, Internal Medicine, Psychiatry Keywords: diabetes-related distress, impact of diabetes and depression on life, diabetes and depression prevalence, depression screening, comorbid diabetes and depression management, type 2 diabetes and depression, type 1 diabetes and depression, depression , diabetes and depression

Polycystic ovarian syndrome (PCOS) is considered the most common endocrine disorder affecting females in today's world. Although it has been primarily studied and discussed in terms of its reproductive symptoms such as infertility, amenorrhea or oligomenorrhea, acne, hirsutism, and mood disorders, there is yet another unexplored and under-diagnosed category in the PCOS spectrum of diseases: its cardio-metabolic consequences. PCOS patients are prone to these abnormalities from a very young age, increasing their morbidity and mortality rates compared to their regular counterparts. The usual pathogenesis of PCOS is a culmination of several genetic and environmental factors. Regarding its cardio-metabolic aspects, insulin resistance (IR) is said to be the single most important cause of a variety of metabolic risk factors, including type 2 diabetes mellitus (T2DM), metabolic syndrome (MetS), dyslipidemia, obesity, and hypertension (HTN), whereas a few other non-traditional factors such as C-reactive protein (CRP), carotid intima-media thickness (IMT), coronary artery calcification (CAC), and endothelial dysfunction are also said to be increased in PCOS patients, further increasing their risk of complications due to cardiovascular diseases (CVD). A timely diagnosis and adequate treatment of these risk factors by using lifestyle interventions, diet, and/or medications are essential to reduce the burden of PCOS in today's world. This article has highlighted an array of traditional and non-traditional cardio-metabolic consequences PCOS patients are prone to and their systematic pathogenesis. In addition, an outline of recommendations has been given in the pharmacological and non-pharmacological sections of this article, which may benefit doctors in managing this challenging condition.

Multiple sclerosis (MS) is a chronic disease affecting the brain and the spinal cord. It is a chronic inflammatory demyelinating disease of the central nervous system. It is the leading cause of non-traumatic disability in young adults. The clinical course of the disease is quite variable, ranging from stable chronic disease to rapidly evolving debilitating disease. The pathogenesis of MS is not fully understood. Still, there has been a rapid shift in understanding the immune pathology of MS away from pure T cell-mediated disease to B cells and microglia/astrocytes having a vital role in the pathogenesis of MS. This has helped in the emergence of new therapies for management. Effective treatment of MS requires a multidisciplinary approach to manage acute attacks, prevent relapses and disease progression and treat the disabling symptoms associated with the disease. In this review, we discuss the pathogenesis of MS, management of acute relapses, disease-modifying therapies in MS, new drugs and drugs currently in trial for MS and the symptomatic treatment of MS. All language search was conducted on Google Scholar, PubMed, MEDLINE, and Embase till February 2022. The following search strings and medical subheadings (MeSH) were used: "Multiple Sclerosis", "Pathogenesis of MS", and "Disease-modifying therapies in MS". We explored literature on the pathogenic mechanisms behind MS, management of acute relapses, disease-modifying therapies in MS and symptomatic management.
