Impostorism is prevalent in medical students and negatively impacts wellness, contributing to stress and burnout. Perceived competence is noted as one attribute underlying impostorism. A curricular change that resulted in improved United States Medical Licensing Examination (USMLE) Step 1 scores and student self-perceptions of preparedness for clinical training was used as a natural experiment to assess the effects higher competence/preparedness, based on an objective indicator and self-perceptions, on impostorism, [...]

Anecdotal evidence suggests the possible association of psychiatric disorders with Mӧbius sequence, although the evidence is not conclusive. Intermittent presentation of auto-aggressive outbursts, in particular, could be related to Mӧbius sequence, different from the common psychotic symptoms. The present report describes the clinical case of a young man with Mӧbius syndrome who exhibited a complex representation of severe mental retardation and concomitant psychiatric disorders. Extremely rare psychiatric disorder [...]

Patients receiving immunosuppressive therapy for inflammatory bowel disease may be susceptible to non-cirrhotic portal hypertension, now referred to as porto-sinusoidal vascular disease. Here we describe a patient treated with long-term azathioprine for Crohn’s disease who developed porto-sinusoidal vascular disease with obliterative portal venopathy without nodular regenerative hyperplasia on histology. Specific signs of portal hypertension were present, including porto-systemic collaterals on imaging. Histopathol [...]

Keratinocytes are particularly vulnerable to oxidative stress due to their function as the primary natural protective barrier exposed to chemicals, rays, and pollution to stimulate the formation of free radicals in the body. Two factors of interest correlate with cellular senescence under oxidative stress. These include regulating antioxidant synthesis, which maintains free-radical homeostasis through the Nrf2 gene, and the prevention of telomere shortening, which involves the collaboration of human telomerase gene [...]

There are several definitions of sympathy, empathy, and compassion on the internet. I have chosen the above definitions to emphasize their salient differences, for the following reason: In medical school, in the early 1960s, we were taught not to sympathize with patients, but to empathize: By empathizing, one can retain some professional objectivity toward the patient, in order to be of some help. To sympathize, on the other hand, was to immerse oneself in the patient’s suffering and lose one’s professional per [...]

Wheat (Triticum aestivum L.) is pivotal to global food security, with its energy-rich grains that are also the major vegetable protein source in human diets. Decades of primary emphasis on grain yield improvement have delivered increased gains worldwide, but the grain protein content has declined. Since amino acids are biosynthetic precursors of proteins, this research hypothesized that their contents in the wholegrain flour have also been impacted by past wheat breeding. To test this, the free amino acid content o [...]

(1) Background: Hereditary Pancreatitis is a rare cause of acute pancreatitis. These patients usually present at a young age with recurrent episodes of acute pancreatitis that usually progresses to chronic pancreatitis with associated endocrine and exocrine failure. Hereditary pancreatitis also carries an increased lifetime risk of pancreatic adenocarcinoma. These high risk patients need early intervention where appropriate by specialist multidisciplinary teams and tailored long term management. (2) Methods [...]

Expanded industrial globalization has resulted in the release of high concentrations of heavy metals into environmental water sources and soils. Phytoremediation may help to remove these heavy metals from contaminated soils. Tall fescue (Festuca arundinacea Shreb.) exhibits phytoremediation potential due to its endurance and high stress tolerances. Here, we report photochemical and structural responses in tall fescue to acute and chronic doses of heavy metals, copper (Cu) and hexavalent chromium (Cr(VI)). Visual si [...]

Due to its similar characteristics to titanium, niobium has become an attractive alternative in photocatalytic processes. Research indicates that titania has an optimal percentage of phases resulting in a commercial catalyst, P25, that contains more than 70% anatase with a minor amount of rutile and a small amount of amorphous phase. On the other hand, for Nb2O5, percentage optimization was little explored in the literature, which consists of studying the phases obtained via heat treatment individually and in diffe [...]

Chronic constipation and irritable bowel syndrome (IBS) are two of the most common functional gastrointestinal disorders, both of which negatively affect the quality of life of the patients. Since people may have co-existing symptoms of multiple disorders, chronic constipation and IBS with predominant constipation cannot be clearly distinguished. In this cross-sectional study, data were obtained from self-administered questionnaires to assess the prevalence of chronic constipation and IBS, and their overlap, among [...]
