AIM: The treadmill walking test with post-exercise pressure measurement can be used as a diagnostic test and could classify peripheral arterial disease of the lower limbs. It can also exclude the diagnosis allowing to raise the possibility of differential diagnoses. In this study, we assessed the feasibility of performing treadmill test by advanced practice nurse to assess suspected lower extremity peripheral artery disease patients. DESIGN AND METHOD: This is a longitudinal monocentric study to assess the feasibility of a treadmill walking test performed by an advanced practice nurse...

The field of bone tissue engineering is steadily being improved by novel experimental approaches. Nevertheless, microbial adhesion after scaffold implantation remains a limitation that could lead to the impairment of the regeneration process, or scaffold rejection. The present study introduces a methodology that employs laser-based strategies for the development of antimicrobial interfaces on tricalcium phosphate-hydroxyapatite (TCP-HA) scaffolds. The outer surfaces of the ceramic scaffolds with inner porosity were structured using a femtosecond laser (λ = 800 nm; τ = 70 fs) for developing micropatterns and altering local surface roughness...

OBJECTIVE: In this single-blinded randomized controlled trial, we compared the "Test in-Train Out" structured home-based exercise program (TiTo-SHB) with the traditional "go home and walk" exercise intervention in people with peripheral artery disease (PAD). METHODS: Peripheral artery disease patients at Leriche-Fontaine's stage II were randomized to receive TiTo-SHB or walking advice (C-WA). The TiTo-SHB group performed two daily 8-min sessions of pain-free interval walking at progressive low-to-moderate speed maintained with a metronome...

We report a case of robotic abdominoperineal resection for rectal cancer with Leriche syndrome. Case: A 75-year-old male. Colonoscopy, which was performed due to persistent diarrhea, revealed type 2 lower rectal circumferential tumor. Pathological examination revealed adenocarcinoma. Computed tomography revealed no distant metastasis, and incidentally complete occlusion from the abdominal aorta to both common iliac arteries. He was diagnosed to rectal cancer(RbRaP, cT3N0M0, cStage Ⅱa)with Leriche syndrome...

The incidence of esophagogastric junction cancer has been increasing, leading to growing interest in surgical treatment. Leriche syndrome, characterized by occlusion limited to the infrarenal aorta, has not been reported to be associated with ischemic enteritis, and there are no previous reports on the surgical approaches for esophagogastric junction cancer in this disease.We describe the case of a male patient in his fifties with lower abdominal pain and melena who was diagnosed with esophagogastric junction cancer, Leriche syndrome, and ischemic enteritis...

INTRODUCTION: Predicting the risk associated with vascular surgery in older adult patients has become increasingly challenging, primarily due to limitations in existing risk assessment tools. This study aimed to evaluate the utility of gait speed, a clinical indicator of frailty, in enhancing the prediction of mortality and morbidity in older adult patients undergoing vascular surgery. METHODS: A single-center prospective cohort study was conducted, involving older adult patients undergoing vascular surgery at four tertiary care hospitals between 2021 and 2022...

We report the effect of tail-tethering on vesiculation and complete unbinding of bilayered membranes. Amphiphilic molecules of a bolalipid, resembling the tail-tethered molecular structure of archaeal lipids, with two identical zwitterionic phosphatidylcholine headgroups self-assemble into a large flat lamellar membrane, in contrast to the multilamellar vesicles (MLVs) observed in its counterpart, monopolar nontethered zwitterionic lipids. The antivesiculation is confirmed by small-angle X-ray scattering (SAXS) and cryogenic transmission electron microscopy (cyro-TEM)...

Various efforts have been made to develop antibacterial biomaterials capable of also sustaining bone remodulation to be used as bone substitutes and reduce patient infection rates and related costs. In this work, beta-tricalcium phosphate (β-TCP) was chosen due to its known biocompatibility and use as a bone substitute. Metal dopants were incorporated into the crystal structure of the β-TCP, and disks were produced from this material. Magnesium and strontium, as well as copper and silver, were chosen as dopants to improve the osteogenic and antibacterial properties, respectively...

Aortoiliac occlusive disease (AIOD), also known as Leriche syndrome, is a form of peripheral artery disease (PAD) that involves narrowing, and in severe cases, complete occlusion, of infrarenal abdominal aorta and/or iliac and femoropopliteal arteries. It classically presents as a triad of symptoms, i.e., leg pain, erectile dysfunction, and abnormally weak or absent femoral pulses. If untreated, it can progress to ischemia and gangrene of the affected regions of pelvis and lower extremities. Like any other PAD, AIOD is most commonly caused by atherosclerosis and usually occurs in strong association with severe cardiovascular diseases...

INTRODUCTION: Aortoiliac arterial disease is a chronic progressive disease which is characterized by steno-occlusive changes in the aorta and iliac arteries. The gold standard for the treatment of patients with the advanced stage of the disease is aorto-bifemoral reconstruction. Patients with circumferential juxtarenal calcifications of the aorta bear a high risk of intraoperative complications, due to difficult cross-clamping in such zones. CASE REPORT: We present a case of a 73-year-old patient who has been admitted due to left leg rest pain and second toe ulceration...

Leriche syndrome is an aortoiliac occlusive arterial disease comprising decreased peripheral pulses, claudication, and erectile dysfunction. We present a case of a 60-year-old male with abdominal pain and hematochezia who was diagnosed with hemorrhoids. The patient also had associated leg cramps on both sides and lower limb weakness. Further evaluation of the patient with imaging revealed occlusion of the distal descending abdominal aorta below the level of renal arteries and the iliac arteries. An incidental finding of Leriche syndrome was evident...

We highlighted in this current paper similar prolonged respiratory presentation with COVID-19 pneumonia in four severely immunocompromised patients currently being treated with anti-CD20 monoclonal antibodies (mAbs), such as ocrelizumab and rituximab, for multiple sclerosis or rheumatoid polyarthritis. Real-time reverse transcription-polymerase chain reaction on a nasopharyngeal swab specimen was negative in all patients. SARS-CoV-2 infection was confirmed from bronchoalveolar lavage fluid. A high titer of post-vaccine COVID-19 convalescent plasma was administered with complete recovery in all patients...

RNA-binding proteins (RBPs) are found at replication forks, but their direct interaction with DNA-embedded RNA species remains unexplored. Here, we report that p53-binding protein 1 (53BP1), involved in the DNA damage and replication stress response, is an RBP that directly interacts with Okazaki fragments in the absence of external stress. The recruitment of 53BP1 to nascent DNA shows susceptibility to in situ ribonuclease A treatment and is dependent on PRIM1, which synthesizes the RNA primer of Okazaki fragments...

BACKGROUD: Management of severe COVID-19 patients admitted to ICU considerably evolved during the first months of the pandemic. It is unclear, however, whether these changes improved long-term survival of these critically ill patients. METHODS: We conducted a retrospective cohort study in adults with COVID-19 pneumonia admitted to a French ICU between February 2020 and January 2021, a timeframe that covered the first two waves of the pandemic. Primary outcome was to compare long-term survival between the first and second waves...

OBJECTIVES: The current study aims to report midterm results of patients treated with endovascular intervention, kissing stent, or covered endovascular reconstruction of the aortic bifurcation, for Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation. METHODS: Eighteen patients who have intermittent claudication or chronic limb threatening ischemia with Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation enrolled to the study between January 2018 and January 2021...

BACKGROUND: Regional changes in corticostriatal transmission induced by phasic dopaminergic signals are an essential feature of the neural network responsible for instrumental reinforcement during discovery of an action. However, the timing of signals that are thought to contribute to the induction of corticostriatal plasticity is difficult to reconcile within the framework of behavioural reinforcement learning, because the reinforcer is normally delayed relative to the selection and execution of causally-related actions...

To quantify an individual's subjective pain severity, standardized pain rating scales such as the numeric rating scale (NRS), visual analog scale (VAS), or McGill pain questionnaire (MPQ) are commonly used to assess pain on a numerical scale. However, these scales are often biased and fail to capture the complexity of pain experiences. In contrast, clinical practice often requires patients to report areas of pain by drawing on a body diagram, which is an effective but qualitative tool. The method presented here extracts quantifiable metrics from pain body diagrams (PBDs) which are validated against the NRS, VAS, and MPQ pain scales...
