Background The COVID-19 pandemic has adversely affected medical education and training programs worldwide. Early investigations have shown that surgical residents face a lot of challenges in these unprecedented times. This study aims to assess the impact of the COVID-19 pandemic on surgical education and training in a developing country. Methods This cross-sectional study was conducted in Allied Hospitals of Rawalpindi Medical University, Rawalpindi, Pakistan from June 2021 to July 2021. A structured questionnaire designed by the researchers was distributed to all surgery departments, and surgical residents who consented to participate in this study were included. Results A total of 152 residents participated in this study, of which 53 (34.9%) were in general surgery and 99 (65.1%) in various surgical allied specialties. Of the residents, 14.5% reported full transfer from the parent unit to the COVID-19 unit. An increase in emergency surgical procedures was reported by 52.8% of general surgery residents as compared to surgical allied specialties (P = 0.037). Of the residents, 90.1% reported increased stress and anxiety levels, with the number of allied residents significantly higher than general surgery residents (P = 0.031). A total of 125 (82.2%) respondents claimed that fear of contracting the virus affected proper patient evaluation. Conclusion The COVID-19 pandemic has severely impacted the training and psychological well-being of surgical residents.

Background Exposure to gender stereotypes in the media can develop and reinforce these attitudes in children. Individuals who are overweight, have health conditions, or are from a minority ethnic group (IMEG) are both underrepresented and poorly portrayed in the media. Role models can raise the aspirations of young children both professionally and in taking ownership of their health. We aimed to assess how the portrayal and diversity of characters in Disney, Pixar, and Dreamworks animated films have changed over time. Method A cohort study of all main characters in Disney, Pixar, and Dreamworks feature-length, theatrical, animated films from 1937 to 2021 was conducted. The portrayal of characters (R-score divided into negative, neutral, and positive -1, 0, and 1, respectively) was scored. The proportion of individuals with certain protected characteristics (sex, increased body mass index, physical or mental health conditions, being from an IMEG or part of the lesbian, gay, bisexual, transexual, and queer community) was also recorded. Results In total, 116 films and 1,275 characters were included. From the 1930s to 2020s, the proportion of women in films increased (16.7% to 47.3%, p=0.008) and their representation was more positive (mean R-score = -0.10 (SD:0.692) versus 0.49 (SD:0.837), p<0.001, respectively). The portrayal of overweight individuals has improved to a neutral position (mean R-score: -0.67 to 0.0). Both physical and mental illnesses are better portrayed (mean R-score: -0.18 to 0.34, p=0.004 and 0.5 to 1.0, p= 0.019, respectively). IMEGs introduced in 1953 now play more than just negative roles (mean R-score = -1 to 0.76, p=0.008). There is only one explicitly stated homosexual character. The most diverse film is Encanto. Conclusion This is the first study to comprehensively assess the diversity of animated film characters. We have identified an improvement in diversity and the way diverse individuals are portrayed which we hope continues

Background Falls among the adult population are a major global health concern with severe repercussions for individuals and healthcare systems. The purpose of this study was to investigate the prevalence and associated risk factors of falls in hospitalized patients in order to improve hospital care for elderly adults. Materials and methods The research was conducted at two institutions of tertiary care in Abbottabad, Pakistan. After extensive screening and obtaining informed consent, a total of 210 participants aged 50 and older were enrolled in the study. Mental status, history of falls, ambulation/elimination status, vision, gait/balance, systolic blood pressure, medication use, and predisposing diseases were evaluated using the Long Term Care Fall Risk Assessment Form. Additionally, the Dynamic Gait Index was utilized to evaluate various aspects of gait. Results 58.6% of participants reported a history of falls in the previous year, according to the findings. BMI, imbalance, vertigo, and fear of falling were significantly associated with an increased risk of falls in older individuals. The Long-Term Care Fall Risk Assessment, the Montreal Cognitive Assessment (MoCA), the Dynamic Gait Index (DGI), and the Mini-BESTest scores revealed that patients with a history of falls had inferior functional and cognitive outcomes. Falls were more common among individuals with a robust BMI, especially men. Conclusions The study results highlight the multifactorial nature of falls in the adult population and the need for targeted interventions to address modifiable risk factors. To enhance hospital care for high-risk patients, proactive fall prevention strategies, including regular risk assessments and individualized interventions, should be implemented. This study provides important insights into the prevalence and causes of accidents among hospitalized patients, particularly in developing nations such as Pakistan

Background: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with a poor prognosis. Accurate preoperative assessment using computed tomography (CT) to determine resectability is crucial in ensuring patients are offered the most appropriate therapeutic strategy. Despite the use of classification guidelines, any interobserver variability between reviewing surgeons and radiologists may confound decisions influencing patient treatment pathways.

Methods: In this multicentre observational study, an international group of 96 clinicians (42 hepatopancreatobiliary surgeons and 54 radiologists) were surveyed and asked to report 30 pancreatic CT scans of pancreatic cancer deemed borderline at respective multidisciplinary meetings (MDM). The degree of interobserver agreement in resectability among radiologists and surgeons was assessed and subgroup regression analysis was performed.

Results: Interobserver variability between reviewers was high with no unanimous agreement. Overall interobserver agreement was fair with a kappa value of 0.32 with a higher rate of agreement among radiologists over surgeons.

Conclusion: Interobserver variability among radiologists and surgeons globally is high, calling into question the consistency of clinical decision making for patients with PDAC and suggesting that central review may be required for studies of neoadjuvant or adjuvant approaches in future as well as ongoing quality control initiatives, even amongst experts in the field.

Keratoacanthoma (KA) is widely considered a benign, usually self-resolving, neoplasm distinct from cutaneous squamous cell carcinoma (cSCC), while some consider KA to be indistinguishable from cSCC. Published studies indicate utility for p16, p53, Ki-67 immunostaining and elastic van Gieson (EVG) in the assessment of KA and cSCC. We compared clinical features and staining patterns for p16, p53, Ki-67 and EVG in fully excised KA, cSCC with KA-like features (cSCC-KAL) and other cSCC (cSCC-OTHER). Significant differences between KA, cSCC-KAL and cSCC-OTHER were found for head and neck location (20%, 86%, 84%), and duration <5 months (95%, 63%, 36%). KA shows both a mosaic pattern for p16 (>25-90% of neoplasm area) and peripheral graded pattern for p53 (up to 50% moderate and strong nuclear staining) in 92% compared with 0% of cSCC-KAL and 0% of cSCC-OTHER. In contrast, a highly aberrant pattern (usually null) for one or both p16 and p53, was present in 0% of KA, 83.8% of cSCC-KAL and 90.9% of cSCC-OTHER. Abnormal distribution of Ki-67 beyond the peripheral 1-3 cells was uncommon in KA (4.2%) and common in cSCC-KAL (67.6%) and cSCC-OTHER (88.4%). Moderate to striking entrapment of elastic and collagen fibres was present in the majority of KA (84%), cSCC-KAL (81%) and cSCC-OTHER (65%). KA are clinically distinct neoplasms typically of short duration occurring preferentially outside the head and neck and generally lacking aberrations of p16, p53 and Ki-67, compared with cSCC that have high rates of aberrant or highly aberrant p16, p53 and Ki-67, but EVG lacked specificity.

Esophageal varices are dilated submucosal esophageal veins that connect the portal and systemic circulations. Bleeding esophageal varices is a well-recognized complication of liver cirrhosis.It is known that in active variceal bleeding, treatment needs to be started promptly. Treatments comprise band ligation, sclerotherapy, removable stent placement, balloon tamponade, and transjugular intrahepatic portosystemic shunt (TIPS).We report a case in which hemodynamic stability can be maintained with the use of Purastat to control bleeding

As foundation doctors, we have often found ourselves informing patients that a certain aspect of their medical information cannot be immediately found, either because it is on an electronic system we cannot access, or it is in a hospital that is unlinked to our own. Unsurprisingly, this frequently leaves patients flabbergasted and confused. We started to wonder: if patients' data are entered onto an electronic system: where do those data go? If medical data are searched for, where do those data come from? Why are there so many hidden sources of information that clinicians cannot access? In an ever-increasing digital sphere, electronic data will be the future of holistic health and social care planning, impacting every clinician's day-to-day role. From electronic healthcare records to the use of artificial intelligence solutions, this article will serve as an introduction to how data flows in modern healthcare systems.

Background: Teicoplanin is used for treating infections caused by Gram-positive bacteria. The POSY-TEICO study assessed the safety of a high loading dose (HLD) of teicoplanin (12 mg/kg twice daily) in a real-world setting.

Methods: This prospective study was conducted across six countries in Europe and enrolled adults prescribed HLD of teicoplanin between 2016-2019. The primary objective was to determine the incidence of nephrotoxicity following HLD of teicoplanin over loading dose period. An independent clinical adjudication committee (ICAC) assessed all study outcomes related to nephrotoxicity.

Results: The study included 300 patients (males, 68.3%), with a mean age of 63.1 years and median teicoplanin treatment duration of 16 days (interquartile range: 9-38). Number of patients with bone and joint infection, infective endocarditis, and other severe infections was 176, 36, and 80, respectively. During loading dose period, 41 (13.8%) patients received 3 HLDs and 246 (82.8%) received ≥4 HLDs. Overall, 28 (11.0%) patients (95%CI, 7.4-15.5) experienced nephrotoxicity during loading and 10 (6.9%) patients (95%CI, 3.4-12.4) during maintenance dose periods. Number of patients who experienced nephrotoxicity certainly or possibly related to teicoplanin according to the ICAC was 20 (7.9%; 95%CI, 4.9-11.9), 8 (5.6%; 95%CI, 2.4-10.7) and 33 (12.4%; 95%CI, 8.7-16.9) across three study periods.

Conclusions: HLD of teicoplanin had an acceptable safety profile in patients treated for bone and joint infection, infective endocarditis, and other severe infections and no increased risk of nephrotoxicity was observed. However, patients should be closely monitored when HLDs are administered.

Any type of contact with electricity of low or high voltage can cause injury to the human body with a variable effect on the body. Low-voltage injury is quite common worldwide, there is very less information present in the available literature. The degree of organ damage depends on many factors, which include the duration of electric current exposure, current type, and nature of the affected tissue. The most common presentations are muscle injury, hyperkalemia, pulmonary oedema, and rarely isolated diffuse pulmonary haemorrhage. We present a case of bilateral pulmonary haemorrhage due to electric shock with no visible signs of damage to the chest wall when exposed to a 220 V shock. The diagnosis was confirmed by fresh hemoptysis, chest imaging that showed bilateral perihilar ground glass opacities, and bronchoscopy findings. Given a life-threatening condition, a timely diagnosis is required as massive haemoptysis can occlude the airways leading to hypoxia and mortality

There is an increasing need for inexpensive and rapid screening tests in point-of-care clinical oncology settings. Herein, we develop a swab "dip" test in saliva obtained from consenting patients participating in a lung-cancer-screening programme being undertaken in North West England. In a pilot study, a total of 211 saliva samples (n = 170 benign, 41 designated cancer-positive) were randomly taken during the course of this prospective lung-cancer-screening programme. The samples (sterile Copan blue rayon swabs dipped in saliva) were analysed using attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy. An exploratory analysis using principal component analysis (PCA,) with or without linear discriminant analysis (LDA), was then undertaken. Three pairwise comparisons were undertaken including: (1) benign vs. cancer following swab analysis; (2) benign vs. cancer following swab analysis with the subtraction of dry swab spectra; and (3) benign vs. cancer following swab analysis with the subtraction of wet swab spectra. Consistent and remarkably similar patterns of clustering for the benign control vs. cancer categories, irrespective of whether the swab plus saliva sample was analysed or whether there was a subtraction of wet or dry swab spectra, was observed. In each case, MANOVA demonstrated that this segregation of categories is highly significant. A k-NN (using three nearest neighbours) machine-learning algorithm also showed that the specificity (90%) and sensitivity (75%) are consistent for each pairwise comparison. In detailed analyses, the swab as a substrate did not alter the level of spectral discrimination between benign control vs. cancer saliva samples. These results demonstrate a novel swab "dip" test using saliva as a biofluid that is highly applicable to be rolled out into a larger lung-cancer-screening programme.
