Remission in Type 2 Diabetes
Type 2 diabetes mellitus (T2DM) is a progressive disease with a growing prevalence, associated with an increased risk of complications. The introduction of new classes of antidiabetic drugs into clinical practice has dramatically changed the landscape of diabetes therapy. However, despite the progress made in the pharmacotherapy of T2DM, mitigating the burden of the disease on individuals, societies and health care systems remains a challenge. Remission has emerged as a therapeutic target in T2DM, achievable through a wide range of interventions. Studies have shown that extensive lifestyle changes, such as weight reduction, bariatric surgery, and intensive glucose lowering therapy, can prompt the remission of diabetes, but some unanswered questions remain regarding its long-term effects on diabetic complications. Metabolic surgery and novel classes of glucose-lowering medications are the most effective interventions to induce weight loss and by extension remission in patients with diabetes.

Palonosetron in Cisplatin-Induced Nephrotoxicity
Cisplatin is widely used to treat various types of cancers, but it is often limited by nephrotoxicity. In this study, we employed an integrated in silico and in vivo approach to identify potential treatments for cisplatin-induced nephrotoxicity (CIN). We were able to find that palonosetron, a serotonin type 3 receptor (5-HT3R) antagonist, can suppress CIN. This study supports the use of in silico and in vivo approaches in drug repositioning studies.

Eating Disorders in Women with Polycystic Ovary Syndrome
Polycystic ovary syndrome (PCOS) is a heterogeneous, multifactorial disease that leads to menstrual and ovulatory irregularities, infertility, hyperandrogenism, and metabolic disturbances. It is recognized as the most prevalent endocrine/metabolic disorder in reproductive-aged women. Despite continuous research efforts, the unifying pathophysiological mechanisms that could explain the etiology of this complex disorder are still not fully understood. The interplay between genetic and epigenetic factors, mitochondrial dysfunction, altered protein and miRNA profiles, and environmental factors that also contribute to obesity lead to exaggerated gonadotropin-releasing hormone (GnRH) pulsatility with hypersecretion of luteinizing hormone (LH) and insulin resistance (IR). Compensatory hyperinsulinemia adds to increased ovarian androgen production and impaired oocyte development. The essential role of the frequent coexistence of mental disorders and polycystic ovary syndrome (PCOS) is being increasingly recognized in the management of PCOS patients since it influences the success of weight loss interventions. Patients frequently experience disrupted eating behaviors, evidenced by the high prevalence of eating disorders in this population. Therefore, assessment and potential modification of eating disorders and eating-related behavior might be especially relevant to improve obesity treatment outcomes in this population, which remains the most efficient causal treatment in PCOS patients with high metabolic risk.

Cognitive Behavioral Analysis System of Psychotherapy
The cognitive behavioral analysis system of psychotherapy (CBASP) is a talking therapy, a synthesis model of interpersonal and cognitive and behavioral therapies developed (and patented) by James P. McCullough Jr [2000, 2006] of Virginia Commonwealth University specifically for the treatment of all varieties of DSM-IV chronic depression. CBASP is often mistakenly labeled a variant of cognitive therapy (CT) or cognitive behavioral therapy (CBT) but it is not. McCullough writes that chronic depression (i.e., depressive disorder in adults that lasts continuously for two or more years; one year continuously in adolescents), particularly the type beginning during adolescence (early-onset), is essentially a refractory "mood disorder" arising from traumatic experiences or interpersonal psychological insults delivered by the patient's significant others (nuclear or extended family). The chronic depression mood disorder, at the core, is fueled by a generalized fear of others resulting in a lifetime history of interpersonal avoidance. The disorder rarely remits without proper treatment. Some basic assumptions underlying McCullough's approach to chronic depression and its treatment as a mood disorder are briefly described below.

Ru(II)-Based Photoactivated Chemotherapy Agents
Photoactivated chemotherapy (PACT) is a novel cancer treatment method that has drawn increasing attention due to its high selectivity and low side effects by spatio-temporal control of irradiation. Compared with photodynamic therapy (PDT), oxygen-independent PACT is more suitable for treating hypoxic tumors. By finely tuning ligand structures and coordination configurations, many Ru(II) complexes can undergo photoinduced ligand dissociation, and the resulting Ru(II) aqua species and/or free ligands may have anticancer activity, showing their potential as PACT agents.

Isocitrate Dehydrogenase Mutations in Glioma
Mutations in isocitrate dehydrogenase (IDH) are commonly observed in lower-grade glioma and secondary glioblastomas. IDH mutants confer a neomorphic enzyme activity that converts α-ketoglutarate to an oncometabolite D-2-hydroxyglutarate, which impacts cellular epigenetics and metabolism. IDH mutation establishes distinctive patterns in metabolism, cancer biology, and the therapeutic sensitivity of glioma. Thus, a deeper understanding of the roles of IDH mutations is of great value to improve the therapeutic efficacy of glioma and other malignancies that share similar genetic characteristics.

Kidney Issues Associated with COVID-19 Disease
Infection with SARS-CoV-2 and the resulting COVID-19 can cause both lung and kidney damage. SARS-CoV-2 can directly infect renal cells expressing ACE2 receptors, resulting in kidney damage, and acute kidney injury (AKI) has been reported in COVID-19 hospitalized patients. The pathophysiology of COVID-19-associated AKI is multifactorial. Local and systemic inflammation, immune system dysregulation, blood coagulation disorders, and activation of the renin-angiotensin-aldosterone system (RAAS) are factors that contribute to the development of AKI in COVID 19 disease. COVID-19 patients with kidney involvement have a poor prognosis, and patients with chronic kidney disease (CKD) infected with SARS-CoV-2 have an increased mortality risk. CKD patients with COVID-19 may develop end-stage renal disease (ESRD) requiring dialysis. In particular, patients infected with SARS-CoV-2 and requiring dialysis, as well as patients who have undergone kidney transplantation, have an increased risk of mortality and require special consideration. Nephrologists and infectious disease specialists face several clinical dilemmas in the prophylaxis and treatment of CKD patients with COVID-19. This entry presents recent data showing the effects of COVID-19 on the kidneys and CKD patients and the challenges in the management of CKD patients with COVID-19, and discusses treatment strategies for these patients.

Supportive Psychotherapy
Supportive psychotherapy is a psychotherapeutic approach that integrates various therapeutic schools such as psychodynamic and cognitive-behavioral, as well as interpersonal conceptual models and techniques. The aim of supportive psychotherapy is to reduce or to relieve the intensity of manifested or presenting symptoms, distress or disability. It also reduces the extent of behavioral disruptions caused by the patient's psychic conflicts or disturbances. Unlike in psychoanalysis, in which the analyst works to maintain a neutral demeanor as a "blank canvas" for transference, in supportive therapy the therapist engages in a fully emotional, encouraging, and supportive relationship with the patient as a method of furthering healthy defense mechanisms, especially in the context of interpersonal relationships. Supportive psychotherapy can be used as treatment for a variety of physical, mental, and emotional ailments, and consists of a variety of strategies and techniques in which therapists or other licensed professionals can treat their patients. The objective of the therapist is to reinforce the patient's healthy and adaptive patterns of thought behaviors in order to reduce the intrapsychic conflicts that produce symptoms of mental disorders.
