Myeloproliferative neoplasms (MPN) are chronic hematological disorders marked by the abnormal proliferation of bone marrow cells. The most commonly encountered forms are polycythemia vera (PV), primary myelofibrosis (PMF), and essential thrombocythemia (ET). These disorders are generally associated with increases in blood components, which can lead to conditions like splenomegaly, thrombosis, bleeding tendencies, and a heightened risk of progressing to acute leukemia. ⋯ Upon adjusting the significance threshold to PFDR < 0.20, 16 immune cell phenotypes were significantly associated with MPN. Among these, 11 were found to exert a protective effect against MPN, 5 phenotypes were associated with an elevated risk of MPN. This research highlights a significant association between various immune cell phenotypes and the risk of developing MPN, thereby advancing our understanding of the intricate interplay between immune cell traits and the progression of MPN.

Observational Study
Optimal wearable camera mount locations for medical supervision during simulated out-of-hospital cardiopulmonary resuscitation.
The quality of the visual information transmitted from a scene is crucial for effective medical supervision in prehospital settings. This study investigated the influence of wearable camera mount locations on visibility during simulated out-of-hospital cardiopulmonary resuscitation. A prospective, observational, non-randomized simulation study was conducted to replicate a cardiac arrest scenario adhering to an advanced life support (ALS) protocol. ⋯ Wearable camera mount location significantly affected visibility during simulated resuscitation. Mounting cameras closer to eye level provided the most accurate visual data. Further research using objective measures, such as artificial intelligence, and evaluating the visibility of wearable cameras in real-world situations is warranted to optimize simulation-based training for prehospital care.

Case Reports
Bilateral thalamic infarction with posterior cerebral artery variant (the arcade artery): A case report.
Bilateral thalamic infarction is a rare type of posterior circulation stroke, and it often presents with a reduced level of consciousness in the elderly. Arteriosclerosis is the primary etiology of bilateral thalamic infarction, including conditions such as native vessel stenosis or arterial-to-arterial embolism. Cardiogenic or paradoxical embolism can also lead to thrombosis of the perforator branches innervating the thalamus, and these emboli tend to disintegrate and lead to multiple lesions, even in elderly patients. ⋯ The elderly experiencing a sudden drop in consciousness should be evaluated for thalamic lesions, primarily cerebral infarction in the posterior circulation. Anatomical artery variations may be helpful in attributing multiple and bilateral lesions to a single source of embolism. Digital subtraction angiography and transesophageal echocardiography can help to clarify the etiological categorization and formulate a secondary prevention strategy for cerebral infarction. Paradoxical embolism is a diagnostic dilemma in the elderly population, and treatment principles must be integrated with guidelines, the prospectively validated patent foramen ovale-associated stroke causal likelihood risk stratification system, interdisciplinary collaboration and customized analysis.

Observational Study
Assessment of a manual therapy and acupressure method as a treatment of nonspecific low back pain: A prospective, observational and non-interventional cohort study.
The first-line treatment for nonspecific low back pain (LBP) relief is physical exercise; however, there is no uniformity in recommendations regarding the type of exercise, and physicians predominantly prescribe pharmacological treatments. This creates a treatment gap in non-pharmacological management of LBP. Preliminary data suggest that manual therapy and acupressure could be relevant therapeutic options. ⋯ This was associated with an improved Dallas Pain Questionnaire score, indicating a reduced impact of LBP on daily activities (-27.2 ± 2.0% on Day 21 and -35.8 ± 2.0% on Day 42, P < .001). Posttreatment, most participants (86.3%) reported reduced analgesic intake compared to baseline, and 83.3% were very satisfied with the therapy. A significant and clinically relevant reduction in lumbar pain was observed after 2 sessions of manual therapy combined with acupressure, paving the way for future clinical research.

Sacrococcygeal pilonidal disease (SPD) is a chronic inflammatory condition primarily affecting young males. This case report details the perioperative anesthetic management of a patient undergoing SPD surgery under subarachnoid anesthesia. ⋯ Thorough preoperative assessment of local and systemic infection status is essential in SPD patients undergoing subarachnoid anesthesia. Intraoperative positional changes may affect the level of subarachnoid block, requiring vigilant monitoring of vital signs and respiratory function. Postoperative care should focus on potential anesthetic complications and wound care requirements. Individualized anesthetic management strategies are crucial for ensuring patient safety.
