Autoimmune hepatitis after COVID-19 infection.

We report the case of a 58-year-old male patient presenting with clinical and laboratory findings indicative of acute hepatitis. Abdominal ultrasound excluded biliary tract abnormalities. Two weeks prior, the patient had contracted COVID-19.

Acceptability and Feasibility of eSCCIP: Results From a Pilot Study of the Electronic Surviving Cancer Competently Intervention Program.

Background: Providing high-quality psychosocial care to parents and other primary caregivers of children with cancer (henceforth referred to as caregivers) is important, given the numerous challenges associated with a pediatric cancer diagnosis and the increased risk for negative psychosocial sequelae among caregivers. The Electronic Surviving Cancer Competently Intervention Program (eSCCIP) is a psychosocial eHealth intervention for caregivers, developed using an iterative, user-centered process.

Method: eSCCIP was tested in a single-arm pilot trial at Nemours Children's Hospital, Delaware (NCT05333601).

Infection with SARS-CoV-2 as a potential achalasia trigger.

Idiopathic achalasia is a chronic oesophageal motility disorder caused by loss of inhibitory neurons at the esophageal myenteric plexus resulting in incomplete relaxation of the lower oesophageal sphincter and abnormal peristaltism.  Among the possible causes of this, an immune response secondary to infection by some viruses has been implicated. SARS-CoV-2 could be considered among them.

Ectopic ACTH syndrome in a patient with Crohn's disease.

We present the case of a 62-year-old man with Crohn's disease who consulted for abdominal pain and lower limbs edema. The patient developed Cushing's syndrome due to ectopic secretion of ACTH. Diagnostic imaging tests showed multiple metastatic liver lesions and asymmetric thickening of the ileum, that was suspected as the primary tumor.

Partnering With Stakeholders to Inform the Co-Design of a Psychosocial Intervention for Prenatally Diagnosed Congenital Heart Disease.

Input from diverse stakeholders is critical to the process of designing healthcare interventions. This study applied a novel mixed-methods, stakeholder-engaged approach to co-design a psychosocial intervention for mothers expecting a baby with congenital heart disease (CHD) and their partners to promote family wellbeing. The research team included parents and clinicians from 8 health systems.

Shift of zero-dispersion wavelength in bent optical fibers.

The understanding of how bending modifies the dispersion of optical fibers, in particular, the zero-dispersion wavelength (λ), is essential in the development of compact nonlinear optical devices such as parametric amplifiers, wavelength converters, soliton lasers and frequency comb generators. Typically, substantial variations in the parametric gain and/or conversion efficiency are significant for changes in λ of ~0.1 nm, which occur for variations on the bending radius (Rb) of 1 cm or less.

Colloid-polymer mixtures under slit confinement.

We report a NVT molecular dynamic study of colloid-polymer mixtures under slit confinement. For this purpose, we are employing the Asakura-Oosawa model for studying colloidal particles, polymer coils, and hard walls as the external confining field. The colloid-polymer size ratio, q, is varied in the range 1⩾q⩾0.

Prognostic value of inflammatory markers (notably cytokines and procalcitonin), nutritional assessment, and organ function in patients with sepsis.

Objective: Procalcitonin is useful for the diagnosis of sepsis, but its prognostic value regarding mortality is unclear. Our objective was to determine the prognostic value of procalcitonin determined at the onset of sepsis, and to compare it with other markers of inflammatory response, malnutrition and organ dysfunction data.

Methods: We studied 253 hospitalized patients (146 men, 107 women) with a median age of 65 years.

Association of Harris lines and shorter stature with ethanol consumption during growth.

Ethanol consumption may impair bone growth. Transverse radiopaque lines (Harris lines) have been interpreted as manifestations of bone growth arrest due to nutritional stress. It is possible that ethanol consumption during growth leads to Harris lines formation and to a shorter stature.

Rib fractures in chronic alcoholic men: Relationship with feeding habits, social problems, malnutrition, bone alterations, and liver dysfunction.

Rib fractures are common in alcoholics. This high prevalence might be due to ethanol-associated malnutrition, bone disease, liver dysfunction, or the peculiar lifestyle of the alcoholic with frequent trauma and altercations. In this study we try to discern the role of these factors on rib fracture (assessed on a plain thoracic X-ray film) in 81 consecutive alcoholic patients, 25 of them cirrhotics.

Effect of zinc supplementation on ethanol-mediated bone alterations.

Ethanol consumption leads to bone alterations, mainly osteoporosis. Ethanol itself may directly alter bone synthesis, but other factors, such as accompanying protein malnutrition--frequently observed in alcoholics, chronic alcoholic myopathy with muscle atrophy, alcohol induced hypogonadism or hypercortisolism, or liver damage, may all contribute to altered bone metabolism. Some data suggest that zinc may exert beneficial effects on bone growth.
