Although there are ever increasing reports of extraintestinal human infections caused by Aeromonads, in both immunocompromised and immunocompetent patients, respiratory tract infections remain uncommon. We describe a case of aspiration pneumonia in an immunocompetent patient with multiple sclerosis, caused by a community acquired, multidrug resistant strain of Aeromonas hydrophila sensitive only to meropenem. The case highlights the clinical significance of Aeromonas hydrophila as a respiratory pathogen, as well as the community origin of multidrug resistance and the utility of newer carbapenems in such cases.

Objective: Antipsychotic medications may cause tardive dyskinesia (TD), an often-irreversible movement disorder characterized by involuntary movements that are typically stereotypic, choreiform, or dystonic and may impair quality of life. This study evaluated others’ perceptions of abnormal TD movements in professional and social situations. Methods: This was an experimental, randomized, blinded, digital survey in a general population sample. Participants were randomized 1:1 into a test or control group to view a video of a professional actor simulating TD movements or no TD movements prior to completing surveys on employment, dating, and friendship domains. Assessments for mild-to-moderate and moderate-to-severe TD movements were conducted separately. Authenticity of abnormal movements and Abnormal Involuntary Movement Scale (AIMS) scores were evaluated by physician experts. Results: Surveys were completed by 2,400 participants each for mild-to-moderate and moderate-to-severe TD. In all domains, participants responded significantly less favorably to persons with TD movements (both mild-to-moderate and moderate-to-severe) than those without TD movements. Fewer participants in the test versus control group for mild-to-moderate and moderate-to-severe TD, respectively, considered the candidate as a potential employee (29.2% and 22.7% fewer), found him/her attractive (20.5% and 18.7% fewer), and were interested in becoming friends with him/her (12.3% and 16.5% fewer). Conclusion Professional actors simulating TD movements were perceived more negatively than those without TD movements in employment, dating, and friendship domains. To our knowledge, this is the first randomized study to quantify professional and social stigma associated with TD movements that may reduce opportunities for gainful employment, marital status, and an effective support system.

The endoplasmic reticulum (ER) is an important subcellular organelle that is involved in numerous activities required to achieve and maintain functional proteins in addition to its role in the biosynthesis of lipids and as a repository of intracellular Ca²⁺. The inability of the ER to cope with protein folding beyond its capacity causes disturbances that evoke ER stress. Cells possess molecular mechanisms aimed at clearing unwanted cargo from the ER lumen as an adaptive response, but failing to do so navigates the system towards cell death. This systemic approach is called the unfolded protein response. Aging insults cells through various perturbations in homeostasis that involve curtailing ER function by mitigating the expression of its resident chaperones and enzymes. Here the unfolded protein response (UPR) cannot protect the cell due to the weakening of its protective arm, which exacerbates imbalanced homeostasis. Aging predisposed breast malignancy activates the UPR, but tumor cells maneuver the mechanistic details of the UPR, favoring tumorigenesis and thereby eliciting a treacherous condition. Tumor cells exploit UPR pathways via crosstalk involving various signaling cascades that usher tumor cells to immortality. This review aims to present a collection of data that can delineate the missing links of molecular signatures between aging and breast cancer.
