Evaluating general surgeons’ perspectives Infante Altamirano, Martin; Lujan, Henry J. Proctoring is a well-established teaching method in minimally invasive surgery, shown to enhance surgical safety and reduce operative time while facilitating faster skill acquisition. With the growing adoption of robotic platforms across multiple specialties, and the increasing interest among surgeons in integrating robotics into their practice, proctoring has re-emerged as an important training technique. While its benefits in laparoscopy are well documented, evidence regarding its role in robotic surgery-particularly from surgeons’ perspectives-remains limited. We conducted an online survey among general surgeons who had received proctoring sessions during their surgical careers. The aim was to assess their perceptions of proctoring in robotic surgery, focusing on its impact on their learning process, operative times, and integration into daily practice. Respondents were also invited to provide qualitative feedback on specific benefits of proctoring and areas for improvement. Of the 97 proctored surgeons invited to participate, 32 (33%) completed the survey. The majority were male, with a median of 15 years of professional experience. Most surgeons reported receiving proctoring for 2–4 cases, with credentialing cited as the most common reason. A statistically significant association was observed between the number of proctored cases and the perceived reduction in the learning curve (p = 0.0019). Surgeons also reported greater confidence in managing complex cases after proctoring (p = 0.0051) and increased adoption of robotics in their daily practice (p = 0.015). Proctoring appears to be a valuable educational tool for general surgeons incorporating robotic surgery. It helps shorten the learning curve, builds confidence in managing complex cases, and supports the integration of robotics into routine practice. In addition, proctoring connects trainees with experienced surgeons, enabling personalized guidance and meaningful knowledge exchange. Constructive feedback between proctor and trainee is essential to maximize the effectiveness of this training approach. 2026-12-01T00:00:00Z http://hdl.handle.net/10757/687668 Correction to: Principles of Surgical Treatment of Soft Tissue Sarcomas (Cancers, (2025), 17, 3, (401), 10.3390/cancers17030401) Gonzalez, Marcos R.; Mendez-Guerra, Carolina; Goh, Megan H.; Pretell-Mazzini, Juan In the original publication [1], there was a mistake: Table 3 and its citations in the main text were missing.

PrEP has been used in various countries globally and in Latin America as a public health measure. In Peru, the greatest increase in HIV incidence in recent years has occurred in the age group of 20–29 years and 15–19 years, this being an important range to be able to implement prevention measures. Objectives: To determine the prevalence of awareness of HIV PrEP and to explore the knowledge and attitudes regarding its use among men who have sex with men (MSM) aged 18–29 years in Lima, Peru. Methods: Explanatory sequential mixed method study whose central component is quantitative. A survey (non-probabilistic descriptive cross-sectional) and a virtual interview (phenomenological approach) were used for data collection. Results: Of 100 seronegative MSM surveyed, 49 % were aware of PrEP. In the qualitative component, it was found that most participants obtained information casually through their social networks. It was also found that they had significant concern about the adverse effects of PrEP, which was mentioned as a barrier to its use. Conclusion: Almost half of MSM are aware of the existence of PrEP, a medication that helps prevent HIV. However, it is important to find more reliable sources of information about PrEP because the fear of adverse effects and ignorance about it are limitations to its consumption. 2025-07-01T00:00:00Z http://hdl.handle.net/10757/687655 Sleep Quality and Cardiovascular Adaptation in Health Sciences University Students Ortega-Contreras, Aruna Marcela; Caycho-Infantes, Maria Jazmin; Sánchez-Huamash, Claudia María Introduction: It is important to have a good cardiovascular adaptation; sleep quality influences the autonomic system, affecting heart rate and blood pressure. The evidence about the relationship between both variables is still insufficient; its measurement is diverse, as are the results. The objective was to evaluate the association between sleep quality and cardiovascular adaptation in health sciences university students. Methods: Cross-sectional and analytical observational study, carried out on 106 students from the Faculty of a private university in Lima (Peru). The Pittsburgh Sleep Quality Index (psqi) was applied to evaluate the sleep quality, the Ruffier-Dickson Test to assess the cardiovascular adaptation, the Alcohol Use Disorders Identification Test (audit) to identify the risk of alcoholism, and the International Physical Activity Questionnaire (ipaq) to determine the physical activity. Results: 75.5 % of participants had poor sleep quality, and 26.4 % had inefficient or poor cardiovascular adaptation. The prevalence of inefficient or poor cardiovascular adaptation in those with poor sleep quality was 1.66 times higher than the prevalence of inefficient or poor cardiovascular adaptation in those with good sleep quality, but this difference was not statistically significant (pr = 1.66; p = 0.321). Conclusions: No association was found between sleep quality and cardiovascular adaptation in health sciences university students. 2025-05-01T00:00:00Z http://hdl.handle.net/10757/687201 Empathetic communication in higher education: Implications for teacher success Bartra-Rivero, Karina Raquel; Armesto-Céspedes, Miguel Sebastián; Barrantes, Fanny E.; Guzmán-Melgar, Catalina Chepa; Rodriguez-Barboza, Jhonny Richard; Chavarri-Joo, Eduardo Francisco This study examines the relationship between teachers' empathetic communication and their academic performance, focusing on two dimensions: empathetic concern and perspective taking. The main objective was to determine if there is a positive and significant relationship between empathetic communication and teaching performance in the university context. A descriptive correlational design was employed to analyze data collected from 364 students from private universities in Lima. Twenty-four items of empathetic communication and 23 of teaching performance were evaluated using a Likert scale survey. As a result, Spearman correlation analyses revealed a positive and significant correlation between empathetic communication and teaching performance (r = 0.211, P < 0.01). Furthermore, positive, and significant correlations were found between empathetic concern (r = 0.279, P < 0.01) and perspective taking (r = 0.166, P < 0.01) with teaching performance. It is concluded that empathetic communication is positively associated with teaching performance, highlighting the importance of developing empathetic communication skills in teachers to enhance their effectiveness in the classroom. However, caution is advised to balance empathy to avoid potential biases or deviations in teaching. It is recommended to focus teacher training programs on strengthening these social skills to optimize the teaching learning process. 2025-07-01T00:00:00Z http://hdl.handle.net/10757/687175 Underdiagnosed obstructive sleep apnea detected by respiratory polygraphy in hospitalized patients with heart failure at a tertiary hospital in Lima-Peru Bazán Lavanda, Eduardo; Camones Huerta, José; Raraz Rivera, Cecilia; Vásquez Ramírez, Nikole; Ayala Díaz, Pedro; Cruzado Grau, Carlos; Novoa Millones, Luis; Rodríguez Hurtado, Diana Background: Obstructive Sleep Apnea (OSA) is often undiagnosed in heart failure (HF) patients. Early identification using affordable sleep studies could improve patient outcomes in resource-limited clinical settings like Peru. The objective was to determine the frequency of OSA in hospitalized HF patients using respiratory polygraphy (RP) (Sleep Study Type III). Materials and methods: A cross-sectional study was conducted. We included patients >18 years, hospitalized with exacerbated HF, and a STOP-BANG score ≥ 3. Enrolled patients underwent overnight RP using ApneaLink Air™. Data collected included clinical parameters, the Epworth Sleepiness Scale, and echocardiography results. Statistical analysis was carried out using R Studio. Results: Of 46 enrolled patients, 39 underwent successful RP; 84.61% were diagnosed with OSA. Patients exhibited a mean Apnea-Hypopnea Index (AHI) of 14.41 ± 10.08/h with mild (51.28%), moderate (25.64%), and severe (7.69%) cases. Symptoms associated with OSA included a lack of restorative sleep and concentration problems. RP data showed a mean minimum SpO2% of 76.85 ± 9.99% and an Oxygen Desaturation Index (ODI) of 20.01 ± 10.66. Correlation analysis indicated a strong positive correlation between AHI and ODI (r = 0.73, p < 0.001) and a moderate negative correlation between AHI and LVEF (r =-0.64, p = 0.056). Conclusion: This study reveals a high frequency of previously undiagnosed OSA among hospitalized heart failure patients in our institution, indicating the importance of active screening in this high-risk population. 2025-04-01T00:00:00Z
