RESUMEN
BACKGROUND: Fever is characterized by an upregulation of the thermoregulatory set-point after the body encounters any pathological challenge. It is accompanied by uncomfortable sickness behaviors and may be harmful in patients with other comorbidities. We have explored the impact of an Ayurvedic medicine, Fevogrit, in an endotoxin (lipopolysaccharide)-induced fever model in Wistar rats. METHODS: Active phytoconstituents of Fevogrit were identified and quantified using ultra-high-performance liquid chromatography (UHPLC) platform. For the in-vivo study, fever was induced in male Wistar rats by the intraperitoneal administration of lipopolysaccharide (LPS), obtained from Escherichia coli. The animals were allocated to normal control, disease control, Paracetamol treated and Fevogrit treated groups. The rectal temperature of animals was recorded at different time points using a digital thermometer. At the 6-h time point, levels of TNF-α, IL-1ß and IL-6 cytokines were analyzed in serum. Additionally, the mRNA expression of these cytokines was determined in hypothalamus, 24 h post-LPS administration. RESULTS: UHPLC analysis of Fevogrit revealed the presence of picroside I, picroside II, vanillic acid, cinnamic acid, magnoflorine and cordifolioside A, as bioactive constituents with known anti-inflammatory properties. Fevogrit treatment efficiently reduces the LPS-induced rise in the rectal temperature of animals. The levels and gene expression of TNF-α, IL-1ß and IL-6 in serum and hypothalamus, respectively, was also significantly reduced by Fevogrit treatment. CONCLUSION: The findings of the study demonstrated that Fevogrit can suppress LPS-induced fever by inhibiting peripheral or central inflammatory signaling pathways and could well be a viable treatment for infection-induced increase in body temperatures.
RESUMEN
Ovarian cancer presenting as an isolated pancreatic metastasis after years of treatment is extremely rare. Most such patients are easily misdiagnosed as a case of primary pancreatic cancer. We herein describe a unique case of posttreatment high-grade serous papillary ovarian carcinoma metastasizing to the pancreas that mimicked primary pancreatic cancer and caused a diagnostic dilemma. The approach to such a case, pathogenesis, differential diagnosis, management, and a brief literature review is also presented.
RESUMEN
In this manuscript, we demonstrate a visible-light driven dimerization of para-quinone methides using eosin Y catalyst via a reductive homocoupling process. This mild and operationally simple methodology was found to be compatible with a variety of differently substituted para-quinone methides and a broad range of tetra-arylethane derivatives were obtained in moderate to good yields (47%-87%).
RESUMEN
College students with more emotional support experience lower levels of anxiety and other psychosocial and behavioral problems. During the COVID-19 pandemic, the emotional well-being of college students was additionally challenged by an abrupt shift to distance learning followed by a return to face-to-face classes. In this exploratory study, we compared the levels of perceived emotional support and anxiety among incoming first-year undergraduate students, prior to starting classes, which included different learning modes in five semesters of instruction from 2021-2023 (three distance semesters and two face-to-face semesters). Data from 8659 undergraduate students were extracted from a Mexican state university database, corresponding to students' responses collected during new student orientation week. Participants were students in the arts and humanities (9.7%), social and legal sciences (38%), life and health sciences (28.9%), and engineering and architecture (23.4%). Anxiety levels were measured with the GAD-7 scale, and emotional support was measured using a subscale of the PERACT-R (To go through with resilience) inventory. Comparisons of emotional support and anxiety scores among semesters revealed highly significant differences with small effect sizes. Anxiety levels increased significantly with mean average of 6.65 SD(5.52) during the baseline measure to the highest in 2022-2 to 7.53 SD(5.3) and Emotional Support decreased systematically each semester from baseline mean = 8.03 SD(2.0) to the lowest 7.52 SD(1.8) in 2022-2. The results show that a return to face-to-face classes was associated with increased anxiety levels, whereas levels of emotional support systematically decreased across the five semesters. MANOVA analysis revealed significant differences in anxiety and emotional support scores between semesters, with peaks during the learning mode semester that students returned to face-to-face classes after distance learning even after adjusting for gender. Given that the effect of emotional support on anxiety may be related to success in future educational and professional activities, it is important to develop interventions to restore and increase college students' emotional support levels and develop anxiety management strategies.

The COVID-19 pandemic precipitated drastic changes in cancer care. Its impact on the U.S. head and neck cancer population has yet to be fully understood. This study aims to understand the impact of pandemic-related changes on the head and neck cancer population. An observational study of head and neck cancer patients at a single institution during the spring of 2020 and 2019 was performed. Clinical characteristics and survival outcomes were analyzed. In 2020, 54 head and neck cancer patients were evaluated in the department of radiation oncology vs. 74 patients seen in 2019; 42% of the patients were female in 2019 versus 24% in 2020 (p = 0.036). The median follow-up time was 19.4 and 31 months for 2020 and 2019, respectively. After adjusting for stage, the relapse-free survival probability at 6 and 12 months was 79% and 69% in 2020 vs. 96% and 89% in 2019, respectively (p = 0.036). There was no significant difference in the overall survival, with 94% and 89% in 2020 and 2019, respectively (p = 0.61). Twenty-one percent of patients received induction chemotherapy in 2020 versus 5% in 2019 (p = 0.011); significantly more treatment incompletions occurred in 2020, 9% vs. 0% in 2019 (p = 0.012). Moreover, the stage-adjusted RFS differed between cohorts, suggesting head and neck cancer patients seen during the initial wave of COVID-19 may experience worse oncologic outcomes.

Background The competency-based undergraduate medical curriculum has a number of new elements. Few authors have attempted to understand the students' viewpoints on the curriculum. We assessed undergraduate students perspectives and ratings about various elements after 2 years of implementation of the curriculum. Methods We included 240 students (2019 and 2020 admission). An invitation letter-cum-information sheet was sent to all the students by email informing them about the study, keeping their identity confidential and the implied consent. A validated questionnaire based on a 5-point Likert scale including 35 closed-ended questions eliciting the students' perception on various elements of the new curriculum and a rating scale from 1 to 5 was designed. Data collection was done using Google forms. Results Of the 240 respondents, 192 (80%) had positive perceptions for the Foundation Course, Attitude, Ethics and Communication skills, Early Clinical Exposure and Community Health Visits. Integrated Teaching, Small Group Teaching and Assessments were viewed less positively (62.9%-75%) and Self-directed Learning received the lowest positive responses (57%-58%). For training as a doctor, the elements considered most valuable were Early Clinical Exposure (70.4%) and Community Health Visits (70.4%) while the least were Logbooks (35.5%) and Reflections (34.2%). Conclusions Students found Early Clinical Exposure and Community Health Visits the most valuable elements whereas Self-directed Learning, Logbooks and Reflections were rated as the least useful.
