Pulmonary edema is a rare but potentially life-threatening iatrogenic complication after treatment through therapeutic thoracentesis of a collapsed lung due to a hydro- or pneumo-thorax. 

Introduction: Residency training is built on a tripod of research, training, and services. This is well achieved through academic seminar presentations which are held two to three times weekly. This survey aims to examine the presentations of Resident Doctors for Medical Education.Methods: The presentations from 2017 to 2022 were requested and pooled through a submission point. They were assembled and sorted out based on the presenter’s name, specialties, and year of presentation. Results: The presentations covered all the 12 major subspecialties, with General Adult psychiatry having the highest of 41 (20.5%), while Social psychiatry had the lowest of 5 (2.5%). Only 40% followed presentation guidelines, and 30% were well formatted. Conclusion: Compendium 1.0 is a comprehensive encyclopedia of academic presentations that will aid easy accessibility when needed. It is recommended that sessions on academic writing are regular, including plagiarism, referencing, and using writing software applications.

A 43-year-old man presented to the emergency department with syncope following hematemesis. He gave the history of melena for 3 days.

Based on different properties of structure of helical protein molecules some theories of bio-energy transport along the molecular chains have been proposed and established, where the energy is released by hydrolysis of adenosine triphosphate (ATP). A brief survey of past researches on different models and theories of bio-energy, including Davydov’s, Brown et al’s, Schweitzer’s, Cruzeiro-Hansson’s, Forner‘s and Pang’s models were first stated in this paper. Subsequently we studied and reviewed mainly and systematically the properties and stability of the carriers (solitons) transporting the bio-energy at physiological temperature 300K in Pang’s and Davydov’s theories. However, these theoretical models including Davydov’s and Pang’s model were all established based on a periodic and uniform proteins, which are different from practically biological proteins molecules. Therefore, it is very necessary to inspect and verify the validity of the theory of bio-energy transport in really biological protein molecules. These problems were extensively studied by a lot of researchers and using different methods in past thirty years, a considerable number of research results were obtained. I here reviewed the situations and progresses of study on this problem, in which we reviewed the correctness of the theory of bio-energy transport including Davydov’s and Pang’s model and its investigated progresses under influences of structure nonuniformity and disorder, side groups and imported impurities of protein chains as well as the thermal perturbation and damping of medium arising from the biological temperature of the systems. The structure nonuniformity arises from the disorder distribution of sequence of masses of amino acid residues and side groups and imported impurities, which results in the changes and fluctuations of the spring constant, dipole-dipole interaction, exciton-phonon coupling constant, diagonal disorder or ground state energy and chain-chain interaction among the molecular channels in the dynamic equations in different models. The influences of structure nonuniformity, side groups and imported impurities as well as the thermal perturbation and damping of medium on the bio-energy transport in the proteins with single chain and three chains were studied by differently numerical simulation technique and methods containing the average Hamiltonian way of thermal perturbation, fourth-order Runge-Kutta method, Monte Carlo method, quantum perturbed way and thermodynamic and statistical method, and so on. In this review the numerical simulation results of bio-energy transport in uniform protein molecules, the influence of structure nonuniformity on the bio-energy transport, the effects of temperature of systems on the bio-energy transport and the simultaneous effects of structure nonuniformity, damping and thermal perturbation of proteins on the bio-energy transport in a single chains and helical molecules were included and studied, respectively. The results obtained from these studies and reviews represent that Davydov’s soliton is really unstable, but Pang’s soliton is stable at physiologic temperature 300K and underinfluences of structure nonuniformity or disorder, side groups, imported impurities and damping of medium, which is consistent with analytic results. Thus we can still conclude that the soliton in Pang’s model is exactly a carrier of the bio-energy transport, Pang’s theory is appropriate to helical protein molecules.

The catamenial pneumothorax is defined as the accumulation of air in the pleural cavity that appears in women infrequently and spontaneously with various clinical presentations. Actually, it is considered as an extremely rare entity with few cases described in the literature, that is the reason why the etiology is still discussed. However, a strong association with thoracic endometriosis syndrome has been found. We want to emphasize how the importance of conducting a diagnosis and having a timely management would improve the quality of life of the patient and give a better prognosis of the disease. Thus, a case report of a 38-year-old female patient who was receiving hormone therapy as a treatment for abdominal endometriosis and repetitive pneumothorax was presented. In the video-assisted thoracoscopy we saw diaphragmatic lesions and pneumothorax during the perioperative and postoperative period. Emphasize the importance of a detailed inspection of each intrathoracic organ during the surgical procedure, we also showed how the intraoperative pleurodesis, the placement of a mesh on the diaphragm and the continuity of the hormonal treatment, seems to be an effective therapy to prevent recurrences and have a better control of the disease. 

A 53-year-old male presented to the Emergency Department (ED) with multisystem trauma and respiratory distress following a blunt-force injury to his anterior left neck. CT imaging showed extensive subcutaneous emphysema and pneumomediastinum. A chest X-ray showed elevation of the left hemidiaphragm suggesting phrenic nerve injury which was confirmed by bedside ultrasonographic examination of the left hemidiaphragm. Flexible bronchoscopy demonstrated tracheal rupture. The patient was treated supportively and recovered without surgical treatment. Trauma-induced hemidiaphragmatic paralysis is rarely reported. This case represents a clinical scenario with demonstrable anatomic correlations, and a clinical reminder that phrenic nerve injury should be included in the differential diagnosis of respiratory distress in a trauma patient.

Evening and weekend imaging services at outpatient radiology centers offer extended access to diagnostic imaging, potentially increasing patient satisfaction and accessibility, especially for underserved populations. This review explores the benefits and challenges associated with these after-hours operations, focusing on health equity, patient satisfaction, economic considerations, energy and cost savings, and the impact on healthcare professionals. Findings indicate that while after-hours operations can enhance patient satisfaction and access, they also pose challenges such as increased operational costs and staff fatigue. Strategies for improvement include optimizing shift schedules, leveraging technology for better scheduling and communication, and enhancing patient-centered care. Collaborative efforts among imaging centers can further improve service delivery and efficiency.

To evaluate the safety and efficacy of weight-based mycophenolate mofetil (MMF) dosing in adult kidney transplant recipients (KTR), this single-center retrospective study of adult KTR compared biopsy-proven acute rejection (BPAR), infections, hospitalizations, granulocyte colony-stimulating factor (G-CSF) use, and MMF dose changes within one year of transplant pre-and post-implementation of a weight-based MMF dosing protocol. Adult patients who received a kidney transplant at University Health Transplant Institute were reviewed for inclusion. Patients in the weight-based MMF group received 1000 mg twice daily by the first clinic visit if ≥ 80 kg, 750 mg twice daily if 50-79 kg, and 500 mg twice daily if < 50 kg. Patients in the fixed-dose MMF group received MMF 1000 mg twice daily. A total of 170 KTR (50.0% ≥ 80 kg, 44.1% 50-79 kg, 5.9% < 50 kg) were included. Baseline characteristics were similar between groups. The majority of patients were middle-aged Hispanic males and received lymphocyte-depleting induction therapy. Incidences of BPAR, infection, and hospitalization were similar between both groups at one-year post-transplant. Weight-based MMF dosing is safe and effective in adult KTR.

Background: Around 75% of seniors seeking treatment for injuries in Emergency Departments (ED) are discharged home with minor injuries that put them at risk of functional decline in the following months. Objectives: To 1) describe seniors’ characteristics using or not physiotherapy services following ED visits for minor injuries and 2) examine their functional status according to physiotherapy use. Methods: Secondary data analyses of the Canadian Emergency Team Initiative cohort study. Participants were 65 years and older, discharged home after consulting EDs for minor injuries and assessed three times: ED, 3- and 6-months. Physiotherapy use was recorded as yes/no. Functional status was measured using the Older American Resources Scale (OARS). Multivariate linear regressions were used to examine change in OARS scores over time, accounting for confounders. Results: Among the 2169 participants, 565 (26%) received physiotherapy, and 1604 (74%) did not. Physiotherapy users were more likely females (71% vs. 64%), more educated, and less cognitively impaired. The overall change in OARS at 6 months was -0.31/28 points (95% CI: -0.55; -0.28) with no difference across groups after adjustment. Subgroup analyses among frail seniors showed that physiotherapy users maintained their function while non-users lost clinically significant function (-0.02 vs. -1.26/28 points, p = 0.03). Among the severely injured (Injury Severity Scale ≥ 5), physiotherapy users’ results were higher by almost 1/28 points (p = 0.03) compared to non-users. Conclusion: These results suggest that among seniors discharged home after consulting the ED for minor injuries, the frail and severely injured may benefit from being systematically referred to physiotherapy services. 

Background: Patients with myocardial infarction (MI) often experience anxiety, depression and poor quality of life (QoL) compared with a normative population. Mood disturbances and QoL have been extensively investigated, but only a few studies have examined the long-term effects of MI on these complex phenomena. Aims: To examine the levels and associated predictors of anxiety, depression, and QoL in patients 2 years after MI. Methods: This was a single center, observational study of patients with MI (n=377, 22% women, median age 66 years). Two years after MI (2012-2014), the patients were asked to answer the Hospital Anxiety and Depression Scale (HADS) and EuroQol 5-dimension (EQ-5D-3L) questionnaires. Results: Most patients experienced neither anxiety (87%, 95% confidence interval [CI]: 83-90%) nor depression (94%, 95% CI: 92-97%) 2 years post-MI. Elderly patients experienced more depression than younger patients (p=0.003) and women had higher anxiety levels than men (p=0.009). Most patients had “no problems” with any of the EQ-5D-3L dimensions (72-98%), but 48% (95% CI: 43%-53%) self-reported at least “some problems” with pain/discomfort. In a multiple logistic regression model (EQ-5D-3L) higher age (p<0.001) and female sex (p<0.001) were associated with more pain/discomfort. Female sex (p=0.047) and prior MI (p=0.038) were associated with anxiety/depression. History of heart failure was associated with worse mobility (p=0.005) and problems with usual activities (p=0.006). The median total health status of the patients (EQ-VAS) was 78 (95% CI: 75-80)
