Medical personality change (MPC) is a codable diagnosis (i.e., F07.0) that deserves consideration when a patient is inexplicably no longer "acting like him/herself." Its presentation ranges from subtle to severe and is often characterized by bafflingly poor judgment and impairment in several aspects of a person's life. Despite the global impact that MPC can have on a patient's functioning, occupation, and relationships, this condition receives far less clinical consideration than better known syndromes such as depression or anxiety and is often likely incorrectly formulated as such.

There are few evidence-informed guidelines and findings to show that the use of sitters improves patient safety; overall, it is a costly intervention to address patients with disruptive behaviors.

When a patient is found to be lacking capacity to make a medical decision, the medical team is advised to turn to the patient's most appropriate surrogate decision maker (hereafter, surrogate) to make a choice on behalf of the patient. The assumption made by the medical team is that the surrogate will have the capacity to make appropriate medical decisions on behalf of the patient. At times though, the capacity of the surrogate himself may be called into question, leading to uncertainty in terms of how best to proceed in the care of the patient. Consultation-liaison psychiatrists are commonly consulted to assess a patient's capacity to make a particular medical decision, but their role assisting in cases of incapacitated surrogates is less clear.

The coronavirus pandemic has changed health care rapidly and dramatically.

The pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has emerged as one of the biggest health threats of our generation. A significant portion of patients are presenting with delirium and neuropsychiatric sequelae of the disease. Unique examination findings and responses to treatment have been identified.

Coronovirus disease 2019 (COVID-19) first broke out in Wuhan, Hubei Province, China, in 2019, and now it spreads in more than 100 countries around the world. On January 30th, the World Health Organization (WHO) declared COVID-19 a public health emergency of international concern. It was classified as a pandemic by the WHO on March 11, 2020. With the increase in the number of cases reported by various countries every day, the COVID-19 pandemic has attracted more and more attention around the world. At the same time, this public health emergency has caused a variety of psychological problems, such as panic disorder, anxiety, and depression. In addition, the Wuhan Mental Health Center's analysis of 2144 calls from the psychological hotline from February 4 to February 20, 2020, showed that the general public accounted for 70%, medical workers accounted for 2.2%, patients with mental disorders accounted for 19.5%, and other personnel accounted for 8.3% (https://mp.weixin.qq.com/s/kmff1vnaLsT2d9xQkK5pwg).

Patients with psychiatric illnesses are particularly vulnerable to highly contagious, droplet-spread organisms such as SARS-CoV-2. Patients with mental illnesses may not be able to consistently follow up behavioral prescriptions to avoid contagion, and they are frequently found in settings with close contact and inadequate infection control, such as group homes, homeless shelters, residential rehabilitation centers, and correctional facilities. Furthermore, inpatient psychiatry settings are generally designed as communal spaces, with heavy emphasis on group and milieu therapies. As such, inpatient psychiatry services are vulnerable to rampant spread of contagion.

Chloroquine and hydroxychloroquine are among several experimental treatments being investigated in the urgent response to the coronavirus disease-2019. With increased use of these medications, physicians need to become knowledgeable of these drugs' neuropsychiatric side effects and interactions with psychiatric medications.

The purpose of this study was to describe the medical complications of anorexia nervosa (AN) to enable a consult-liaison psychiatrist to be familiar with these complications when involved with the care of a hospitalized patient with AN.

Determining the optimal timing and structure for a core residency rotation in consultation-liaison psychiatry (CLP) remains a key challenge for program directors and rotation leaders. Previous surveys have been conducted regarding these questions, and guidelines from national organizations have been issued, but practices remain varied among institutions.

The scientific literature in consultation-liaison psychiatry continually expands, and remaining familiar with the most current literature is challenging for practicing clinicians. The Guidelines and Evidence-Based Medicine Subcommittee of the Academy of Consultation-Liaison Psychiatry writes quarterly annotations of articles of interest to help Academy members gain familiarity with the most current evidence-based practices. These annotations are available on the Academy Website.

Infections related to intravenous drug use and opioid use disorders (OUDs) are increasing nationwide. Endocarditis is a recognized complication of intravenous drug use, and inpatient treatment typically focuses on infection management without attention to underlying addiction.
