The Application of Augmented Reality Technology in Free Flap Reconstruction: A Systematic Review.

Introduction: Augmented reality (AR) is an emerging technology in microsurgery for free flap reconstruction. AR allows surgeons to superimpose preoperative CT images onto the patient, providing real-time insight into the underlying anatomy and aiding in the decision-making process; however, there is limited empirical evidence supporting the effectiveness of this modality. We conducted a systematic review to investigate whether the use of AR devices in free flap reconstruction correlates with improved outcomes.

Infant and parent heart rates during a babywearing procedure: Evidence for autonomic coregulation.

Babywearing is the practice of carrying an infant in a baby carrier, which may provide an inexpensive, nonpharmacological intervention for the parent-infant dyads to handle mental stressors, such as pain and anxiety, especially among vulnerable infants. This study investigated the influence of babywearing on parent-infant autonomic coregulation based on the changes in the HR of mother-infant and father-infant dyads for infants with neonatal abstinence syndrome (NAS). Guided by the Calming Cycle Theory as the framework, the correlation between parent HR and infant HR and the difference in the mother-infant dyad (n = 17) compared to the father-infant dyad (n = 8) were examined.

Wage Disparities across Immigrant Generations: Education, Segregation, or Unequal Pay?

Immigrants and their native-born children often face considerable wage penalties relative to natives, but less is known about whether this inequality arises through differences in educational qualifications, segregation across occupations and establishments, or unequal pay for the same work. Using linked employer-employee data from Norway, the authors ask whether immigrant-native wage disparities 1) reflect differences in detailed educational qualifications, labor market segregation, or within-job pay differences; 2) differ by immigrant generation; and 3) vary across different segments of the labor market. They find that immigrant-native wage disparities primarily reflect sorting into lower-paying jobs, and that wage disadvantages are considerably reduced across immigrant generations.

A national survey comparing practice patterns and residency training satisfaction for categorical dermatology versus combined internal medicine and dermatology trained physicians.

Combined internal medicine and dermatology (med-derm) training programs were created to advance complex medical dermatology and inpatient dermatology care. A prior study demonstrated that compared to categorical dermatology residents, med-derm residents had less program satisfaction, yet indicated a stronger desire to pursue careers in academia. No follow-up data on practice patterns after training has been reported.

Patch Testing to Chlorhexidine Digluconate, 1% Aqueous: North American Contact Dermatitis Group Experience, 2015-2020.

Chlorhexidine is an antiseptic that may cause allergic contact dermatitis. To describe the epidemiology of chlorhexidine allergy and characterize positive patch test reactions. This retrospective study analyzed patients patch tested to chlorhexidine digluconate 1% aqueous by the North American Contact Dermatitis Group, 2015-2020.

Hitchhiking spider: a case of unilateral vasculitis.

A 63-year-old man presented with two days of palpable purpura over the right anterior shin and calf with notable point tenderness on the distal mid-calf without any palpable deep abnormality. Localized right calf pain worsened with walking and was associated with headache, chills, fatigue, and low-grade fevers. A punch biopsy of the anterior right lower leg showed necrotizing neutrophilic vasculitis of superficial and deep vessels.

The increased efficiency of porphyran hydrolysis by constructing a multifunctional enzyme complex from marine microorganisms.

Porphyran, a polysaccharide composed of red algae, is a source of a multifunctional oligosaccharide material and raw biomass with various physiological activities. The glycolysis of porphyrans into oligosaccharides through various porphyranases is an approach for obtaining high-quality and promising alternative resources. In this study, porphyran was extracted from Porphyra yezoensis and used as a research substrate.

Transition of care in patients with epidermolysis bullosa: A survey study.

There are little published data on the transition of care in EB. We conducted a survey study recruiting EB patients from the Dystrophic EB Research Association (debra) website and centers caring for high numbers of EB patients in the United States and internationally from Sept 17, 2019 to Nov 3, 2021. The majority of participants had not discussed the transition of care with their healthcare providers, nor the healthcare needs to be required as an adult.

Combination Treatment Using Pyruvate Kinase M2 Inhibitors for the Sensitization of High Density Triple-negative Breast Cancer Cells.

Background/aim: Few studies have examined the correlation between pyruvate kinase M2 (PKM2) overexpression and triple-negative breast cancer (TNBC). TNBC is considered incurable with the currently available treatments, highlighting the need for alternative therapeutic targets.

Materials And Methods: PKM2 expression was examined immunohistochemically in human breast tumor samples.

Does Skin Tone Matter? Immigrant Mobility in the U.S. Labor Market.

A rich literature has documented the negative association between dark skin tone and many dimensions of U.S.-born Americans' life chances.

Combination of interferon-expressing oncolytic adenovirus with chemotherapy and radiation is highly synergistic in hamster model of pancreatic cancer.

Recent clinical trials utilizing Interferon-alpha (IFN) in combination with chemoradiation have demonstrated significant improvements in the survival of patients with pancreatic cancer. However, efficacy was limited by the systemic toxicity of IFN and low intratumoral levels of the cytokine. We sought to address these drawbacks by using an Oncolytic Adenovirus expressing IFN (OAd-hamIFN) in combination with chemotherapy and/or radiation in regimens mimicking the IFN-based therapies used in clinical trials.

Oncolytic adenoviruses targeted to Human Papilloma Virus-positive head and neck squamous cell carcinomas.

Objectives: In recent years, the incidence of Human Papilloma Virus (HPV)-positive head and neck squamous cell carcinomas (HNSCC) has markedly increased. Our aim was to design a novel therapeutic agent through the use of conditionally replicative adenoviruses (CRAds) that are targeted to the HPV E6 and E7 oncoproteins.

Methods: Each adenovirus included small deletion(s) in the E1a region of the genome (Δ24 or CB016) intended to allow for selective replication in HPV-positive cells.
