Purpose To quantify the optic nerve head (ONH) and peripapillary retinal nerve fiber layer (pRNFL) thickness in patients with Coronavirus Disease-2019 (COVID-19) and compare the measurements with a healthy control group.Methods In a comparative cross-sectional observational study, ONH and pRNFL thickness were evaluated in patients with a history of COVID-19, at least 2 weeks after recovery from the systemic disease, and compared with an age-matched, normal control group.Results Thirty COVID-19 patients along with 60 age- and gender-matched healthy controls were studied.  https://www.selleckchem.com/products/Eloxatin.html  Mean average pRNFL thickness was 105.0 ± 16.3 µm in the COVID-19 patients, compared to 99.0 ± 9.0 µm in the controls (p = .31). The pRNFL thicknesses in all sectors was higher in patients with a history of COVID-19; however, this did not reach statistical significance. Similarly, ONH parameters were not significantly different between the groups.Conclusion Patients recovered from COVID-19 had unremarkable alterations in the peripapillary RNFL thickness.Abbreviations ONH Optic Nerve HeadRNFL Retinal Nerve Fiber LayerSD-OCT Spectral-Domain Optical Coherence TomographyCOVID-19 Coronavirus Disease 2019SARS-CoV-2 Severe Acute Respiratory Syndrome Coronavirus 2CNS Central Nervous SystemACE Angiotensin-Converting EnzymeRT-PCR Reverse Transcription-Polymerase Chain Reaction.Background The aim of this study was to analyze the prognostic value of pre-treatment hematological parameters in EGFR-mutated non-small cell lung cancer patients treated with tyrosine-kinase inhibitors (TKIs).Patients and methods Patients with EGFR mutations were treated with EGFR-TKIs in the first line until progression/unacceptable toxicity. Hematological parameters were derived from the absolute baseline differential counts of a complete blood count. The associations between the patients' and tumor characteristics were analyzed using Pearson Chi-Square, Fisher's exact, t-test, and Mann-Whitney tests. Cutoff values were determined using ROC curves, and correlation with survival was examined by Kaplan-Meier method and Cox regression.Results Patients with NMR190 more often had paronichia, diarrhea and hyperbilirubinemia.Conclusion Low baseline value of the hematological parameter NMR has shown potential as a routine, low-cost, and minimally invasive predictor of survival in EGFR-TKI-treated NSCLC patients.Limited opportunities exist for university premedical students to gain exposure to the realities of clinical practice through physician shadowing or through a formal curriculum. Medical Professionalism and Observership utilizes didactics, reflective writing, small- and large- group discussions, and clinical observerships to enhance the process of professional identity formation during a critical developmental window of late- adolescence. The pilot semester included a sample of 135 students, all in their sophomore, junior, or senior years of study at Rice University. Students were selected through an application process and paired with physicians at Houston Methodist Hospital based on specialty preference and availability. Students were required to participate in biweekly lectures and discussions and to submit a weekly reflection on topics discussed in the course and their shadowing experiences. Student evaluations were administered to survey changes in students' knowledge and perceptions of the curriculum. Selected reflections were read for evidence of professional identity formation. Lectures increased students' exposure to core competencies within the medical profession and influenced their desire to become physicians. Reflective writings demonstrated integration of these core competencies into the professional identity of students. Structured reflection and didactics, when coupled with physician shadowing, appear to promote integration of the values, beliefs, and attitudes of medical professionalism. Future studies should seek to demonstrate how such a curriculum affects professional identity formation through established measures, and to assess whether such a curriculum may influence students' preparedness for medical training and practice as they progress along their careers.Purpose To report three cases of eyelid involvement by sarcoidosis. In one of them, it mimicked a malignant lesion.Methods Retrospective case reports.Results A 73-year-old man presented with destruction of the left lower eyelid for 2 years. He had granulomatous uveitis in the left eye. Chest CT scan showed parenchymal abnormalities that could correspond to sarcoidosis. Skin biopsy revealed noncaseating granuloma. Oral and topical corticosteroids resulted in improvement of the condition. A 72-year-old female patient presented with cutaneous infiltration of the left upper eyelid for 1 month. Biopsy was consistent with sarcoidosis. Endobronchial biopsies showed interstitial fibrosis. Oral prednisone improved the condition. A 65-year-old female patient presented with edema of the right upper eyelid for 2 months. Full-thickness biopsy showed granuloma without necrosis. There was an improvement with oral steroid.Conclusion Although eyelid involvement in sarcoidosis is uncommon, different forms of presentation, including destructive lesions, can be observed.
  To evaluate the effect of a tele-nutrition counseling program on diet quality, weight, waist circumference, and quality of life in people with spinal cord injury (SCI).
 
  Prospective observational study.
 
  Fifteen participants with SCI were enrolled from an acute inpatient rehabilitation unit and outpatient SCI clinic; ten participants completed the intervention.
 
  Six tele-nutrition counseling sessions over 3 months, utilizing videoconferencing and a photographic food diary.
 
  Weight, waist circumference, Life Satisfaction Index A (LSIA), Knowledge and Nutrition Evaluation with Supplement on Eating Behavior, and Program Satisfaction Survey (PSS).
 
  Ten participants completed both baseline and 3-month follow-up evaluations and were used in this analysis. There were no statistically significant changes from baseline to 3-month follow up in weight, waist circumference, Knowledge and Nutrition Evaluation, and LSIA (P > .48). Using the Supplement on Eating Behavior total score to measure overall changes in healthy food choices, 9 out of 10 participants rated their healthy food choices as improving (P = .
