Multinational perspectives on changes to psychiatric care during the COVID-19 pandemic: a survey of practicing psychiatrists.

Background: The coronavirus disease 2019 (COVID-19) pandemic has resulted in significant upheaval in psychiatric care. Despite survey data collected from psychiatric patients and broad samples of individuals in single countries, there is little quantitative or qualitative data on changes to psychiatric care from the perspective of mental health providers themselves across developing countries.

Methods: To address this gap, we surveyed 27 practicing psychiatrists from Central and Eastern Europe, as well as Africa, the Middle East, and Latin America.

Comparison of Functional and Structural Neural Network Features in Older Adults With Depression With vs Without Apathy and Association With Response to Escitalopram: Secondary Analysis of a Nonrandomized Clinical Trial.

Importance: Apathy is prevalent among individuals with late-life depression and is associated with poor response to pharmacotherapy, including chronicity and disability. Elucidating brain networks associated with apathy and poor treatment outcomes can inform intervention development.

Objectives: To assess the brain network features of apathy among individuals with late-life depression and identify brain network abnormalities associated with poor antidepressant response.

Switch to Hypomania After Discontinuation of Tamoxifen: A Case Report.

Tamoxifen is a synthetic, nonsteroidal antiestrogen widely used in the treatment of hormone-sensitive breast cancer that has also been shown to inhibit the enzyme protein kinase C (PKC). Upregulation of PKC is associated with disruption of prefrontal cortical regulation of thinking and behavior, which can lead to mania-like symptoms in animal models. Lithium and valproate, 2 mood stabilizers that are widely used in the treatment of bipolar disorder, have also been shown to inhibit PKC.

Minocycline augmentation in older adults with persistent depression: an open label proof of concept study.

Less than 40% of depressed older adults treated with an antidepressant achieve remission. Incomplete response to treatment is common. Current augmentation strategies have limited efficacy, and many have side effects that restrict their utilization in older adults.

Dimensions of Poststroke Depression and Neuropsychological Deficits in Older Adults.

Objective: Poststroke depression (PSD) has a heterogeneous presentation and is often accompanied by cognitive impairment. This study aimed to identify distinct dimensions of depressive symptoms in older adults with PSD and to evaluate their relationship to cognitive functioning.

Design: Cross-sectional factor and correlational analyses of patients with poststroke depression.

Improved bioavailability of Azelnidipine gastro retentive tablets-optimization and in-vivo assessment.

Azelnidipine, dihydropyridine based calcium channel blocker has been used for treating ischemic heart disease and cardiac remodeling after myocardial infarction but it is having a low bioavailability due to its poor solubility. The present study is to investigate the formulation and evaluation of floating tablets of Azelnidipine for controlled release and to increase bioavailability by increasing the gastrointestinal transit time and mucoadhesion of drug. The gastro retentive tablets were prepared by direct compression method using different concentrations of combination of Polyoxyethylene oxide WSR 303 as hydrophilic polymer and Potassium bicarbonate as gas generating agent.

Formulation, Optimization, and In vivo Evaluation of Gastroretentive Drug Delivery System of Nifedipine for the Treatment of Preeclampsia.

The study aimed to develop gastroretentive drug delivery system of nifedipine, its optimization, and in vivo evaluation. Bilayered tablet of nifedipine was prepared using central composite design with 3 factors, 5 responses, and 15 experimental trials. Response surface methodology along with numerical and graphical optimization was used to select the best formulation.

White matter abnormalities predict residual negative self-referential thinking following treatment of late-life depression with escitalopram: A preliminary study.

Background: Negative self-referential thinking is a common symptom of depression associated with poor treatment response. In late-life depression, white matter abnormalities may contribute to negative self-referential thoughts following antidepressant treatment. We investigated the association of fractional anisotropy (FA) in select regions of the negative valence system (NVS) with residual negative self-referential thoughts following treatment with escitalopram for late-life depression.

Zeta potential as a novel diagnostic tool for preeclampsia.

Objective: To determine the zeta potential of erythrocyte and its association with morphological changes during preeclampsia so as to use it as a diagnostic tool to determine this pregnancy related complication.

Methods: This retrospective study included 502 pregnant women. Blood samples were collected in 5% dextrose solution from preeclampsia patients (n = 92) and normal pregnant women (n = 337).

Effect on Morphology, Osmotic Fragility and Electro Kinetic Potential of Erythrocytes in Hypertension.

Background: Hypertension is a common health problem concerning a large proportion of population and a leading global risk factor for the burden of cardiovascular disease (CVD). The purpose of this study was to assess the efficacy of the erythrocyte zeta potential as a potential additional indicator for cardiovascular disorder risk so that patients with this can be more rapidly identified and treated.

Methods: In the present study, blood samples were collected in 5% dextrose solution from patients suffering from hypertension and healthy volunteers (Not taken any medication).

Development and Characterization of Solid Self-emulsifying Drug Delivery System of Cilnidipine.

The present investigations highlight the development of solid self-emulsifying drug delivery system (solid-SEDDS) for improved oral delivery of the poorly water-soluble drug; cilnidipine. Liquid SEDDS of the drug were formulated using Capryol 90 as the oil phase, Tween 80 as the surfactant, and Transcutol HP as the co-surfactant after screening various vehicles. The prepared systems were characterized for self-emulsification time, robustness to dilution, % transmittance, globule size, drug release, and thermodynamic stability.

Models of care for late-life depression of the medically ill: examples from chronic obstructive pulmonary disease and stroke.

Depression worsens most treatment outcomes in medically ill older adults. Chronic medical illnesses weaken and demoralize patients and compromise their ability to adhere to treatments requiring consistency and effort. Acute medical illnesses create a psychosocial storm that finds patients and their ecosystem unprepared.

A patient with bipolar disorder and antiphospholipid syndrome.

Antiphospholipidsyndrome (APS) is an autoimmune disorder which causes a hyper-coagulable state characterized by recurrent thrombosis. It has a diverse range of central nervous system manifestations. We describe a case of a 61 year old man with bipolar disorder and APS, and we compare this to a previously reported case.

In vitro and in vivo characterization of novel biomaterial for transdermal application.

Polymers have become an indispensable part in the design of a conventional as well as novel drug delivery system. Gum Copal (GC), a novel biomaterial obtained from Agathis species, is evaluated in the present study for its potential application as a matrix former in transdermal drug delivery systems. GC was initially characterized for various physicochemical properties and then mechanical characterization of the Plasticized films of GC was investigated.
