A 50-year-old woman with a history of permanent atrial fibrillation (AF) treated with radiofrequency catheter ablation (RFCA) 6 months ago was admitted to the respiratory department of a tertiary hospital because of recurrent episodes of pleuritic chest pain in the preceding 5 months. The patient reported multiple visits to a regional hospital, where she was treated with broad-spectrum antibiotics after discovery of a left alveolar consolidation on chest radiograph (Fig 1), subsequently imaged with CT scan (Fig 2). On treatment failure and appearance of a left-sided pleural effusion during outpatient follow-up, the patient was re-admitted. Pleural fluid was obtained via thoracocentesis characterized by exudative features and lymphocytic predominance. Abdomen CT scan, with IV and per os contrast agent, was devoid of findings consistent with malignancy, and serum autoantibody levels were below positivity cut off values (antinuclear, cyclic citrullinated peptide antibody, rheumatoid factor, and anti-neutrophil cytoplasmic antibodies). The patient underwent flexible bronchoscopy without endobronchial pathology on visual inspection. Microbiologic studies and cytological examination of samples obtained by bronchial washing/aspiration yielded no clinically relevant information. Lung perfusion/ventilation scintigraphy was ordered to exclude chronic thromboembolic pulmonary hypertension; however, a deficit in vascularization for the left inferior lobe was found, prompting further investigation (Fig 3). Progression of left inferior lobe consolidation and the presence of a small pericardial effusion became evident on reimaging after a 2-month interval. The patient was empirically started on corticosteroids. After emergence of left hilar lymphadenopathy (< 1 cm), a PET-CT scan was performed. The left lower inferior lobe consolidation, whose metabolic activity pattern was consistent with that of inflammation (standardized uptake value equal to 4.4) (Fig 4), as well as the left sided-pleural effusion were markedly improved compared with previous imaging 20 days after corticosteroid initiation (Fig 2). On the grounds of recalcitrant pleuritic pain and pleural effusion recurrence during corticosteroid tapering, the patient was referred to the respiratory department of our university hospital to have her condition diagnosed.

Syncope is common, but there is no clear cause for half of the patients diagnosed with syncope. Although suspected, there is limited evidence that right-to-left shunt (RLS) is related to syncope. This matched case-control study investigated the association between RLS (exposure) and unexplained syncope (outcome).

A substantial proportion of individuals infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), report persisting symptoms weeks and months following acute infection. Estimates on prevalence vary due to differences in study designs, populations, heterogeneity of symptoms and the way symptoms are measured. Common symptoms include fatigue, cognitive impairment and dyspnoea. However, knowledge regarding the nature and risk factors for developing persisting symptoms is still limited. Hence, in this study, we aim to determine the prevalence, severity, risk factors and impact on quality of life of persisting symptoms in the first year following acute SARS-CoV-2 infection.

Sjögren's syndrome (SjS) is an autoimmune disease characterized by the triad of sicca symptoms, fatigue and pain. This diagnosis is usually made in women at the average age of 60 years. Diagnosis is made when sicca symptoms persist for more than three months, after the exclusion of possible differential diagnoses, and using the ACR/EULAR 2016 classification criteria for SjS. Many organs can be affected in the course of this disease. Xerosis cutis and pruritus are the most common skin manifestations, followed by leukocytoclastic vasculitis and subacute cutaneous lupus erythematosus. In addition, SjS patients often have myoarthralgia and neuropsychiatric symptoms. In the long term, attention must be paid to the increased risk of cardiovascular disease and lymphoma. Due to the multiorgan involvement in SjS patients, interdisciplinary care is required.

Osteoarthritis (OA) is characterized by pain and inflammation. Electroacupuncture (EA) and swimming (SW) are non-pharmacological interventions recommended for treating OA. The study evaluated the benefits of electroacupuncture (EA) and swimming (SW) association when compared with isolated protocols in an OA rodent model. Experimental.

Extensor pollicis longus (EPL) tendon spontaneous rupture has been related to numerous risk factors including wrist fractures, rheumatoid arthritis, and steroids administered locally or systemically, as well as repetitive and excessive wrist motion.

Herbal medicine could be effective at treating various illnesses. Hysteroscopy can be an effective method for assessing the uterus in terms of anatomical, physiological and pathological anomalies.

The complexity of brain activity involved in the generation of the experience of pain makes it hard to identify neural markers able to predict pain states. The within and between subjects variability of pain hinders the predictive potential of machine learning models trained across participants. This challenge can be tackled by implementing deep learning classifiers based on convolutional neural networks (CNNs). We targeted phase-based connectivity in the alpha band recorded with electroencephalography (EEG) during resting states and sensory conditions (eyes open [O] and closed [C] as resting states, and warm [W] and hot [H] water as sensory conditions). Connectivity features were extracted and re-organized as square matrices, because CNNs are effective in detecting the patterns from 2D data. To assess the classifier performance we implemented two complementary approaches: we 1) trained and tested the classifier with data from all participants, and 2) using a leave-one-out approach, that is excluding one participant at a time during training while using their data as a test set. The accuracy of binary classification between pain condition (H) and eyes open resting state (O) was 94.16% with the first approach, and 61.01 % with the leave-one-out approach. Clinical relevance-Further validation of the CNN classifier may help caregivers track the rehabilitation of chronic pain patients and dynamically modify the therapy. Further refinement of the model may allow its application in critical care setting with unresponsive patients to identify pain-like states otherwise incommunicable to medical personnel.

The INSPIRE trial was a Phase 3, open-label, multicenter trial (LTI-301) that enrolled patients with pulmonary arterial hypertension (PAH) ≥ 18 years of age who transitioned to Yutrepia from nebulized treprostinil (Transition) or added Yutrepia to prostacyclin naïve patients on ≤2 nonprostacyclin oral therapies. The objectives of the trial were to evaluate the safety and tolerability of Yutrepia (dry-powder formulation of treprostinil) in patients with PAH. The primary safety measures were the incidence of adverse events (AEs) and serious AEs. Exploratory efficacy measures were also assessed during the trial. Transition patients initiated Yutrepia at a dose comparable to their nebulized treprostinil dose while prostacyclin naïve patients received 26.5-mcg QID; up-titration in 26.5-mcg increments was permitted for both groups. A total of 121 patients were enrolled, of which 29 patients discontinued from the trial, with the most common reason being AEs. Eighty percent of the Transition group and 96% of the prostacyclin naïve group titrated to a dose ≥79.5 mcg QID at Day 360, respectively, with one patient achieving a dose of 212-mcg QID. The most common AEs were cough, headache, upper respiratory tract infection, dyspnea, dizziness, throat irritation, diarrhea, chest discomfort, fatigue, and nasopharyngitis. Most of these events were considered treatment-related though mild to moderate in severity and expected for prostacyclin therapy administered by inhalation. In an evaluation of exploratory efficacy measures, patients remained stable or improved over the 1 year of treatment. Yutrepia was found to be a convenient, safe, and well-tolerated inhaled prostacyclin treatment option for PAH patients.

Introduction Nonhealing ulcers have a huge burden on the patient, by having high morbidity in terms of chronic pain, partial or complete loss of function, mental health issues, and social isolation, and can have a massive financial burden on the patient. Various novel therapies have been developed to treat nonhealing ulcers. Platelet-rich fibrin (PRF) has been developed in the recent era initially in the dental world for treating oral ulcers. Now, the role of PRF is strongly established in treating nonhealing ulcers. PRF has an aggregate of a myriad of growth factors and cytokines that stimulate healing of the wounds. In this study, we have compared the efficacy of PRF in treating nonhealing ulcers of the lower limb against normal saline dressings. Aims and objectives This study aims to determine the efficacy of platelet-rich fibrin over normal saline dressings in the treatment of nonhealing ulcers of the lower limb by comparing the percentage reduction in the surface area of wounds after treatment in both groups. Methods Fifty patients with nonhealing ulcers were selected and randomly divided into two groups with 25 patients in each group. Cases were treated with PRF dressings weekly for a period of six weeks. Controls were treated with normal saline dressings weekly for a period of six weeks. The percentage reduction in the size of the ulcer after treatment was recorded in both groups and compared. Patients of age 18-60 with nonhealing ulcers of the lower limb of >12 weeks duration have been included in the study. Patients having wounds with active infection, wound size > 35 cm, uncontrolled diabetes, peripheral vascular disease with Ankle-Brachial Index < 0.9, osteomyelitis of the underlying bone, and immunocompromised state, and patients on antiplatelet drugs have been excluded from the study. Results The mean age of the patients included in the study was 42.88 ± 2.73 years. The mean initial surface of the wound​​​was 14.95± 3.08 cmamong cases and 13.28 ± 2.83 cm among controls. The mean surface area of the wound after six weeks was 1.59 ± 0.78 cm among cases and 11.08 ± 2.74 cm among controls. The mean percentage reduction in the wound size after six weeks of treatment was 89.3% among cases and is significantly higher than in the normal saline group (16.5%) (Mdn = 14.63, U = 23, p < 0.00001). Conclusion Platelet-rich fibrin is an emerging potential topical agent for the treatment of nonhealing ulcers of the lower limbs and is more effective than normal saline dressings and also has the advantage of being cost-effective.
