Mixed Depression: A Mini-Review to Guide Clinical Practice and Future Research Developments

The debate on mixed states (MS) has been intense for decades. However, several points remain controversial from a nosographic, diagnostic, and therapeutic point of view. The different perspectives that have emerged over the years have turned into a large, but heterogeneous, literature body. The present review aims to summarize the evidence on MS, with a particular focus on mixed depression (MxD), in order to provide a guide for clinicians and encourage the development of future research on the topic. First, we review the history of MS, focusing on their different interpretations and categorizations over the centuries. In this section, we also report alternative models to traditional nosography. Second, we describe the main clinical features of MxD and list the most reliable assessment tools. Finally, we summarize the recommendations provided by the main international guidelines for the treatment of MxD. Our review highlights that the different conceptualizations of MS and MxD, the variability of clinical pictures, and the heterogeneous response to pharmacological treatment make MxD a real challenge for clinicians. Further studies are needed to better characterize the phenotypes of patients with MxD to help clinicians in the management of this delicate condition.

Interventions for Early-Stage Pericoronitis: Systematic Review of Randomized Clinical Trials

Background: To investigate the efficacy and safety of interventions for early stage pericoronitis. Methods: We searched for randomized controlled trials (RCTs) in databases from inception to July 2020, without language restriction. RCTs assessing adolescents and adults were included. Results: Seven RCT with clinical diversity were included, so, it was not possible to conduct meta-analyses. Individual study data showed an improvement in oral health quality of life in favor of topical benzydamine versus diclofenac capsule (Mean difference (MD) −1.10, 95% Confidence interval (CI) −1.85 to −0.35), and no difference between topical benzydamine and flurbiprofen capsule (MD −0.55 95% CI −1.18 to 0.0). There was no difference between diclofenac and flurbiprofen capsules (MD 0.55, 95% CI −0.29 to 1.39). An imprecise estimate of effects was found for all outcomes, considering (i) oral versus topic pharmacological treatment, (ii) different oral pharmacological treatments, (iii) pharmacological treatment associated with laser versus placebo laser, (iv) pharmacological treatment associated with different mouthwashes, and (v) conventional treatment associated to antimicrobial photodynamic therapy versus conventional treatment, with low to very low certainty of evidence. Conclusions: Until future well-designed studies can be conducted, the clinical decision for early stage pericoronitis should be guided by individual characteristics, settings and financial aspects.

Factors Associated With Pharmacological and Non-pharmacological Treatments Adherence in Patients With Borderline Personality Disorder in Iran

BackgroundBorderline personality disorder is a major mental illness characterized by a sustained relationship instability, impulsive behavior and intense affects. Adherence is a complex behavior, from minor refusals of treatment to inappropriate use of health services or even abandonment of treatment, which can be affected by various factors. Therefore, the present study aimed to investigate the factors affecting pharmacological and non-pharmacological adherence in patients with borderline personality disorder referred to an outpatient referral clinic in Tehran, Iran.MethodsThe study was a retrospective cohort. The files of patients with borderline personality disorder referred to the outpatient clinic of the Tehran Psychiatric Institute were reviewed as the first step. In the next step, we contacted the patients and asked them to fill out the questionnaires. Data were collected using the Drug Attitude Inventory (DAI) questionnaire and a researcher made questionnaire to determine the attitude of patients toward pharmacological and non-pharmacological treatment and therapeutic adherence. After collecting data, patients’ therapeutic acceptance was divided into three groups: poor, partial, good compliance. The data were analyzed by SPSS software version-22.Results Ninety-four patients were involved in the study and fifty four of them were women. In terms of psychotherapy adherence, patients with higher education and hospital admission history have better compliance. Medication attitudes were negative in 54 patients (57.4%), while 40.4% of them stated that psychotherapy or counselling did not help their condition and showed a negative attitude toward non-pharmacological treatment. Additionally, psychotherapy good adherence of the patients (44.7%) was higher than medication good adherence (31.9%). The most common reasons for discontinuation of treatment were medication side effects (53.1%), dissatisfaction with the therapist (40.3%) and then fear of medication dependence (40%). The results showed no relationship between other demographic factors and treatment adherence.ConclusionsResults of the current study show that attitude toward psychotherapy is more positive than pharmacotherapy. In addition, according to the results, working on changeable factors such as patients’ fear of dependence to medication, dissatisfaction with the therapist, and medication side effects may improve patients' treatment adherence.

Synthesis and Anti-Chikungunya Virus (CHIKV) Activity of Novel 1,4-Naphthoquinone Sulfonamide and Sulfonate Ester Derivatives

Chikungunya virus (CHIKV) is a re-emerging disease caused by an alphavirus of the Togaviridae family. Since its first description in 1952, the disease has spread worldwide, affecting populations in both tropical and temperate countries. To date, there is no licensed vaccine or specific pharmacological treatment. Therefore, there is an increasing urgency in developing new antiviral drugs capable of specifically inhibiting viral replication. In the present work, we report the synthesis and antiviral activity evaluation of nineteen naphthoquinone derivatives, containing a sulfonamide or sulfonate group. Cell viability assays indicated a low toxic potential for all tested compounds and inhibitory assays against CHIKV identified five compounds with potent activity. The compounds were also evaluated for their virucidal potential, and the results demonstrated that compound 11a exhibited a virucidal effect higher than 70% in the treatment with 20 µM. Furthermore, in silico studies were performed to predict the antiviral drug targets.
