Cardiovascular Risk Factors as Independent Predictors of Diabetic Retinopathy in Type II Diabetes Mellitus: The Development of a Predictive Model.

: Diabetic retinopathy (DR) is a leading cause of blindness in patients with type 2 diabetes mellitus (T2DM). Cardiovascular risk factors, such as hypertension, obesity, and dyslipidemia, may play a crucial role in the development and progression of DR, though the evidence remains mixed. This study aimed to assess cardiovascular risk factors as independent predictors of DR and to develop a predictive model for DR progression in T2DM patients.

Clinical and Morphological Study of Cervical Squamous Intraepithelial Lesions.

Squamous intraepithelial lesions (SILs) are cancer precursors targeted by secondary prevention of cervical cancer programs that are sometimes difficult to grade accurately. Mena is an actin regulatory protein involved in membrane protrusion, cell motility, in tumor invasion and metastasis. We studied retrospectively 68 cases of patients diagnosed with squamous intraepithelial lesions that received expedited treatment (treatment without colposcopic biopsy).

Direct Air Capture of CO Using Amine/Alumina Sorbents at Cold Temperature.

Rising CO emissions are responsible for increasing global temperatures causing climate change. Significant efforts are underway to develop amine-based sorbents to directly capture CO from air (called direct air capture (DAC)) to combat the effects of climate change. However, the sorbents' performances have usually been evaluated at ambient temperatures (25 °C) or higher, most often under dry conditions.

Air quality changes in NE Romania during the first Covid 19 pandemic wave.

This study analyzes for the first time uniformly and causally the level of pollution and air quality for the NE-Romania Region, one of the poorest region in the European Union. Knowing the level of pollution and air quality in this region, which can be taken as a benchmark due to its positional and economic-geographical attributes, responds to current scientific and practical needs. The study uses an hourly database (for five pollutants and five climate elements), from 2009 to 2020, from 19 air quality monitoring stations in northeastern Romania.

Treating a Large Thoracoabdominal Aneurysm With Aberrant Right Subclavian Artery With a Physician-Modified Graft.

Large thoracoabdominal aortic aneurysms due to chronic aortic dissection in patients with connective tissue disorders such as Loeys-Dietz syndrome present a challenging scenario, particularly in cases of variant anatomy and when patients are not candidates for conventional open repair. We demonstrate how by combining and modifying off-the-shelf devices during a hybrid procedure, one can create an endovascular solution tailored to the patient's complex anatomy, making use of an aberrant right subclavian artery, and allow for good clinical outcomes.

Which learning experiences support an interprofessional identity? A scoping review.

In recent years, health professions researchers have suggested that a dual identity that includes both a professional and interprofessional identity is essential to interprofessionality. This scoping review sought to describe the learning experiences that may support the development of an interprofessional identity, providing direction for future research. A scoping review was conducted to identify papers published between 2000 and 2020 that provided empiric evidence to support the impact of planned or spontaneous learning experiences involving two or more healthcare professions that fostered the development of an "interprofessional identity," or a sense of belonging to an interprofessional community.

A Newly Developed Interprofessional Simulation-Based Training for Airway Management of COVID-19 Patients: Identification of Challenges and Safety Gaps, and Assessment of the Participants' Reaction.

Background: Healthcare providers performing aerosol-generating procedures like airway management are at the highest risk for contamination with coronavirus disease 2019 (COVID-19). We developed an simulation (ISS) airway management training in confirmed or suspected COVID-19 patients for emergency and anesthesiology staff, evaluated participants' reactions, and identified perceived challenges.

Methods: We used a cross-sectional study design incorporating a quantitative questionnaire to describe participants' reaction to the ISS and a qualitative group interview using the plus-delta debriefing modality to explore participants' challenges in acquiring the knowledge and skills required for each learning objective.

We sought to assess practitioners' preferences when initiating a workup for pediatric patients presenting with symptoms concerning for MIS-C.

Methods: In a cross-sectional vignette-based survey, providers were presented with clinical vignettes of a patient presenting with 24 h of fever from a community with high rates of COVID-19.

Sub-Ambient Temperature Direct Air Capture of CO using Amine-Impregnated MIL-101(Cr) Enables Ambient Temperature CO Recovery.

Due to the dramatically increased atmospheric CO concentration and consequential climate change, significant effort has been made to develop sorbents to directly capture CO from ambient air (direct air capture, DAC) to achieve negative CO emissions in the immediate future. However, most developed sorbents have been studied under a limited array of temperature (>20 °C) and humidity conditions. In particular, the dearth of experimental data on DAC at sub-ambient conditions (e.

Caution: Air Embolism Related to Heli-Fx EndoAnchor System in Zone 2 Thoracic Aneurysm Repair.

Purpose: We report a case of significant air embolization to the ascending aorta immediately following deployment of EndoAnchors in the aortic arch during a procedure to correct a type 1A endoleak.

Case Report: The novel Heli-Fx EndoAnchor system (Medtronic Vascular, Santa Rosa, CA, USA) was used to deploy helical anchors in the distal aortic arch during a procedure to correct a type 1A endoleak following Zone 2 thoracic endovascular aortic repair of a saccular proximal descending thoracic aorta aneurysm (DTAA). The patient developed ST-segment elevations principally in the inferior leads and severe hypotension moments after EndoAnchor deployment at the proximal edge of the endograft.

Flexible e-learning video approach to improve fundus examination skills for medical students: a mixed-methods study.

Background: Training for the fundus examination using traditional teaching is challenging, resulting in low generalist physicians' confidence in performing the funduscopic examination. There is growing evidence suggesting a flexible e-learning video approach's value in teaching physical examination procedures. However, whether the flexible e-learning video approach is superior to the traditional, face-to-face (F2F) lecture-based teaching for the funduscopic exam and the cognitive processes supporting its effectiveness has not yet been determined.

"It is this very knowledge that makes us doctors": an applied thematic analysis of how medical students perceive the relevance of biomedical science knowledge to clinical medicine.

Background: Intensive study of the biomedical sciences remains a core component of undergraduate medical education with medical students often completing up to 2 years of biomedical science training prior to entering clerkships. While it is generally accepted that biomedical science knowledge is essential for clinical practice because it forms the basis of clinical reasoning and decision-making, whether medical students perceive an expanded role for their biomedical science knowledge remains to be examined.

Methods: We conducted a qualitative research study to explore how medical students in the first clerkship year perceived the relevance of biomedical science knowledge to clinical medicine during this pivotal time as they begin their transition from students to physicians.

Effect of Extended Aging and Oxidation on Linear Poly(propylenimine)-Mesoporous Silica Composites for CO Capture from Simulated Air and Flue Gas Streams.

Physical aging or degradation of amine-containing polymers and supported amine adsorbents is a critical issue that could limit the practical application of such materials for CO capture. However, to date, there is a scarcity of studies that evaluate the long-term stability of amine-based sorbents without the exclusive use of accelerated aging tests. Here, we demonstrate that extended aging (∼2 years) of linear poly(propylenimine) (LPPI) confined in mesoporous silica (SBA-15) supports does not drastically impact the CO adsorption performance under simulated flue gas (10% CO) and direct air capture (DAC, 400 ppm CO) conditions, although the behavior of the aged sorbents and polymers in the two CO concentration regimes differs.

Organophilic, Superparamagnetic, and Reversibly Thermoresponsive Silica-Polypeptide Core-Shell Particles.

Particles with a superparamagnetic cobalt inner core, silica outer core, and covalently bound homopolypeptide shell were investigated under thermal and magnetic stimuli. The homopolypeptide was poly(ε-carbobenzyloxy-l-lysine), PCBL, which is known to exhibit a thermoreversible coil ⇔ helix transition when dissolved as a pure polymer in cresol. Tethering to a core particle did not prevent PCBL from undergoing this conformational transition, as confirmed by dynamic light scattering and optical rotation, but the transition was broadened compared to that of the untethered polymer.

Diffusion of Rodlike Polymers: Pulsed Gradient Spin Echo NMR of Poly(γ-stearyl-α,l-glutamate) Solutions and the Importance of Helix Stability.

Many natural and synthetic polymers and particles have a rodlike shape, leading to important and intriguing solution behavior, such as high intrinsic viscosities and liquid crystalline phases. Much of what is known about suspensions of rods has been learned by studying helical polypeptides, even though such molecules are not perfectly rigid, smooth cylinders. Previous optical tracer self-diffusion studies of poly(γ-benzyl-α,l-glutamate) (PBLG) revealed that the molecule initially resists topological constraints imposed by neighboring molecules, but diffusion strongly decreases as concentration rises beyond a certain number density.

Nature-Inspired and "Water-Skating" Paper and Polyester Substrates Enabled by the Molecular Structure of Poly(γ-stearyl-α,l-glutamate) Homopolypeptide.

We demonstrate that the molecular structure of a synthetic homopolypeptide that resembles the leg architecture of water strider insects is effective to impart flexible polymeric surfaces with superhydrophobic behavior. Filter paper (FP) and polyester (PET) were modified with a coating consisting of low-molecular weight α-helical poly(γ-stearyl-α,l-glutamate) (PSLG, M = 4500 Da) homopolypeptide. PSLG-coated substrates displayed near to and superhydrophobic behavior (≥150°) as reflected by the contact angle values.

Cerebral embolic protection during endovascular arch replacement.

Despite excellent results in high volume centers, open repair of aortic arch pathology is highly invasive, and can result in significant morbidity and mortality in high risk patients. Near-total and hybrid approaches to aortic arch disease states have emerged as an alternative for patients deemed moderate to high risk for conventional repair. Advantages of these approaches include avoidance of extracorporeal circulation and hypothermic circulatory arrest as well as avoidance of cross clamping, all of which are not well tolerated in high risk patients.
