January 2025

Department of Psychiatry, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

In human activity-recognition scenarios, including head and entire body pose and orientations, recognizing the pose and direction of a pedestrian is considered a complex problem. A person may be traveling in one sideway while focusing his attention on another side. It is occasionally desirable to analyze such orientation estimates using computer-vision tools for automated analysis of pedestrian behavior and intention.

Previous research indicates that the COVID-19 pandemic catalyzed alterations in behaviors that may impact exposures to environmental endocrine-disrupting chemicals. This includes changes in the use of chemicals found in consumer products, food packaging, and exposure to air pollutants. Within the Environmental influences on Child Health Outcomes (ECHO) program, a national consortium initiated to understand the effects of environmental exposures on child health and development, our objective was to assess whether urinary concentrations of a wide range of potential endocrine-disrupting chemicals varied before and during the pandemic.

We examined the relationship between socioeconomic status (SES) and endorsement of honour. We studied the SES-honour link in 5 studies (N = 13,635) with participants recruited in different world regions (the Mediterranean and MENA, East Asian, South-East Asian, and Anglo-Western regions) using measures that tap into various different facets of honour. Findings from these studies revealed that individuals who subjectively perceived themselves as belonging to a higher (vs.

Introduction: Genodermatoses refer to a group of heterogenous rare genetic diseases with cutaneous expression. Several genodermatoses present with multisystem involvement that can range from mild to life-threatening conditions leading to increased morbidity and mortality.

Objective: Given the paucity in the literature in the field of genodermatoses, especially in the Middle East and North Africa (MENA) region, and building upon the first established genodermatoses database based in Lebanon, this study aimed to decipher the genetic basis of two different types of skin-inherited diseases (androgenic alopecia and vitiligo).

Hyperalgesia is a condition marked by an abnormal increase in pain sensitivity, often occurring in response to tissue injury, inflammation, or prolonged exposure to certain medications. Inflammatory mediators, such as cytokines IL-1β, IL-6, and TNF-α, play a central role in this process, amplifying pain perception. Developing effective treatments that address the underlying mechanisms of hyperalgesia is an active field of research.

Background: Cerebrovascular diseases (CVAs) have several risk factors that are categorized as modifiable and nonmodifiable. Periodontal diseases (PD) have a modifiable role in causing CVA, where several studies suggested direct or indirect correlations with systemic diseases. This study aims to summarize, evaluate and analyze all the evidence available in literature, to reach a better understanding of the relation between periodontitis, gingivitis, tooth loss and CVA.

for targeting MRSA virulence: and studies.

Heliyon

January 2025

Department of Biological Sciences, Faculty of Science, Beirut Arab University, Tripoli, 1300, Lebanon.

The present study reports the characterization of the phytochemical content and the antibacterial activity of ethanolic extracts from the leaves (LE) and stems (SE) of against Methicillin resistant (MRSA. Important functional groups were determined by analyzing the FTIR spectra of LE and SE. The phytochemical profiles were analyzed by GC-MS, and these characterized the chemicals according to retention periods and peak regions.

Cutaneous involvement of chronic lymphocytic leukemia (CLL) is rare but has been previously documented to involve the head and neck region. Generally, involvement to the ears is limited to the ear lobule; however, this study presents a unique case of recurrent CLL with cutaneous involvement overlying the auricular ear. The presentation was initially concerning for possible perichondritis but remained unresponsive to antibiotics and steroids.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is still a growing concern in the field of antimicrobial resistance due to its resistance to conventional antibiotics and its association with high mortality rates. Mesenchymal stromal cells (MSCs) have been shown as a promising and attractive alternative treatment for bacterial infections, due to their antibacterial properties and potential to bypass traditional resistance mechanisms. This study aims to shed light on the antibacterial potential of adipose-derived mesenchymal stromal cell (AD-MSC) secretome against clinical isolates of Staphylococcus spp.

Analysis of choroidal markers of activity in pachychoroid disease spectrum.

Graefes Arch Clin Exp Ophthalmol

January 2025

Londrina State University, Avenida Robert Koch, 60, Londrina, CEP 86038-440, Paraná, Brazil.

Purpose: To detect choroidal markers of disease activity in eyes with chronic active unilateral pachychoroid disease spectrum (PDS) compared to the non-active contralateral eyes, based on multimodal imaging and particularly indocyanine green angiography (ICGA).

Methods: An observational retrospective case-control study. The study evaluated individuals diagnosed with chronic active unilateral PDS (group 1) by comparing the eyes with the non-active fellow eyes (group 2).

Objective: As aneurysmal disease is progressive, proximal disease progression and para-anastomotic aneurysms are complications experienced after open infrarenal abdominal aortic aneurysm repair (AAA). As such, fenestrated or branched endovascular repair (F/BEVAR) may be indicated in these patients. Data describing fenestrated endovascular aneurysm repair after prior open repair are limited to institutional databases.

Prognostic utility of assessing ventricular-arterial coupling in arterial hypertension and cardiovascular diseases.

Minerva Cardiol Angiol

January 2025

Department of Anatomy and Embryology, Faculty of Health, Medicine and Life Sciences, Maastricht University, Maastricht, the Netherlands.

The assessment of myocardial function and its coupling with the arterial system, called ventricular-arterial coupling (VAC), is of paramount importance in many clinical fields, from arterial hypertension, which is the main cause of cardiovascular diseases and death, to heart failure. VAC has been the subject of studies for several decades both from an energetic cost and the impact it can exert on cardiovascular performance. Although more attention has been paid to the relationship between the left ventricle and the left arterial circuit in compromised hemodynamic stages, VAC has aroused interest in many other aspects of study, from its application in pathologies of the right sections of the heart to its clinical impact in prevention and cardiovascular risk factors.
