The 150th anniversary of Johan Hjort's birth was celebrated by a symposium held in Bergen on 12–14 June 2019 to take a broad perspective on the origins of, and developments in, fisheries science and thereby examine current issues in fisheries science from different perspectives. To establish this type of non-traditional forum, historians of marine science and marine researchers from around the world met to explore potential new directions. The many transdisciplinary panel discussions, especially on subjects such as "the making of fisheries scientists", revealed the pervading influence of family, educators, role models, and social circumstances. The 11 articles included in this symposium issue present a series of advancements in modern fisheries science, highlighting the contributions of Hjort and his contemporaries, Fyodor Baranov and Harald Dannevig. As expected, the effects of changing ocean climate were a dominant theme, which connected this symposium, and complemented, the 2014 symposium in honour of Johan Hjort's influential treatise released in 1914. Although no ground-breaking paradigms were presented, several new research directions were proposed in a creative atmosphere generated by participants. The social context of science had a key influence in Hjort's day and continues to do so today and into the future. [ABSTRACT FROM AUTHOR]

The article offers information on the psychosocial evolution of women in surgery, along with crude tools and operative techniques used in the surgery. It discusses the efforts for advancing the presence of women in the operating arena. It mentions the role of women in early medical practice varied by the culture towards women.

In patients with multiple co-morbidities, identifying the culprit etiology of cardiac arrest can be challenging. We present a patient who suffered cardiac arrest and was found to have Aortic dissection (AD), pulmonary embolism, extensive thrombosis, and shock, complicating the treatment plan. A 63-year-old man collapsed at work and was found to be pulseless with ventricular fibrillation rhythm, with down time over 30 minutes. He had ischemic cardiomyopathy with 3 vessel disease and chronic total occlusion of left circumflex artery (figure 1). His post-arrest blood pressure was 199/100, heart rate 125 in atrial fibrillation, and he required mechanical ventilation. A computed tomography (CT) of the chest showed DeBakey type IIIB AD from the origin of the left subclavian to the abdominal aorta distal to the renal arteries. Intravenous esmolol and amiodarone were started but the patient developed hypotension requiring vasopressors. Transesophageal echocardiogram demonstrated depressed ejection fraction of 10% and a mobile thrombus in the right atrium extending from the inferior vena cava (IVC). The patient was deemed a poor surgical candidate. Given the IVC thrombus, a CT angiography of the chest was obtained, showing bilateral pulmonary emboli. Decision was made to start therapeutic anticoagulation despite AD. A magnetic resonance imaging of his brain showed bilateral acute infarcts complicating the decision to pursue cardiac catheterization and possible triple antithrombotic therapy. A trial of guideline directed medical therapy with carvedilol was initiated however the patient developed pulmonary edema and shock with predominant suspicion of being cardiogenic. There was poor improvement with inotropes and vasopressors. After multidisciplinary team discussion, mechanical circulatory support (MCS), including extracorporeal membrane oxygenation, was deemed futile due to prolonged down time, and challenging cannulation with extensive AD. The patient's family elected to withdraw care and the patient expired 10 days post-arrest. Use of MCS can be problematic with extensive AD due to challenges with cannulation. Further, there is paucity of evidence on anticoagulation in AD given risk of propagation of the dissection plane, albeit in our patient it was necessary. Multidisciplinary team approach can prioritize such interventions (figure 2). [ABSTRACT FROM AUTHOR]

KAREN ZEY @zippyzey At sixty, I joined Twitter as an emergent writer. My early efforts were couched in humor, but my #cnftweets soon shifted to more nuanced observations of both self and others - an ongoing effort to seek understanding and contentment at this stage of life. The Tiny Truths micro-essay seemed a good fit for my twinges of aging angst. [Extracted from the article]

The article presents a study that determines the effect of the bacteria Lactobacillus acidophilus on necrotizing fasciitis (NF) in diabetic patient. It highlights the case of a 59-year-old female with a medical history of diabetes mellitus type II, presented with abdominal pain along with other complaints. It offers explanation of the effects of Lactobacillus acidophilus and suggests that patients with NF should be treated aggressively to avoid mortality.

BACKGROUND: Fibroadenomas are benign breast tumors; however, more aggressive lesions may mimic or arise within fibroadenomas. We sought to define criteria identifying patients who should undergo surgical excision. METHODS: Patients with a preoperative diagnosis of fibroadenoma, who underwent surgical excision between 2002 and 2011, were retrospectively reviewed. Patients with final pathologic diagnosis of fibroadenoma were compared with those with non-fibroadenoma pathology. RESULTS: Of the 723 patients, 681 (94%) had fibroadenomas on final pathology. The incidence of non-fibroadenoma pathology was 6% (42 patients) and included benign phylloides (23), malignant phylloides (2), atypical ductal hyperplasia (1), intraductal papilloma (5), and other benign pathology (11). No cases of adenocarcinoma were identified. Non-fibroadenoma pathology was associated with age >35, immobile or poorly circumscribed mass, size >2.5 cm, and biopsy not definitive for fibroadenoma. CONCLUSION: Patients with age >35 years, immobile or poorly circumscribed mass, size >2.5 cm, or biopsy not definitive for fibroadenoma should undergo surgical excision. [ABSTRACT FROM AUTHOR]

More than 50 years ago, two investigators described a rare case of multiple esophageal diverticula, which they named esophageal intramural pseudodiverticulosis (EIPD). To this day, the pathogenesis of this condition remains obscure. Several coexisting conditions, such as strictures, esophageal dysmotility, or infection, require medical treatment. We present two typical cases of EIPD and one case of a rare single esophageal intramural diverticulum. [ABSTRACT FROM AUTHOR]
