Background  Most existing objective surgical motion analysis schemes are limited to structured surgical tasks or recognition of motion patterns for certain categories of surgeries. Analyzing instrument motion data with respect to anatomical structures can break the limit, and an anatomical region segmentation algorithm is required for the analysis. Methods  An atlas was generated by manually segmenting the skull base into nine regions, including left/right anterior/posterior ethmoid sinuses, frontal sinus, left and right maxillary sinuses, nasal airway, and sphenoid sinus...

The existence of a gender gap in academia has been a hotly debated topic over the past several decades. It has been argued that due to the gender gap, it is more difficult for women to obtain higher positions. Manuscripts serve as an important measurement of one's accomplishments within a particular field of academia. Here, we analyzed, over the past 3 decades, authorship and other trends in manuscripts published in BONE, one of the premier journals in the field of bone and mineral metabolism. For this study, one complete year of manuscripts was evaluated (e...

Pancreatic tuberculosis (TB) is an extremely rare form of extrapulmonary tuberculosis even in endemic areas that masquerades as a mass or inflammation because of lack of typical clinical manifestations and radiologic features and therefore usually misdiagnosed as a pancreatic malignancy or pancreatitis. Here we present a 23-year-old young man with pancreatic tuberculosis mimicking pancreatic head carcinoma A man who suffered from upper abdominal pain and nausea for half a month was admitted to our hospital...

BACKGROUND: Sedentary behavior (SB) is a significant risk factor for heart disease, diabetes, obesity, and early mortality, particularly among women, and the health consequences associated with SB are independent of physical activity status. Interventions utilizing wearable technologies can improve SB, but their effectiveness is influenced by individual preferences, device engagement strategies, and technological features, which may affect user compliance. Gathering a priori insight from target populations on their preferences for program tools and strategies may assist researchers in identifying effective methods to improve the efficacy of SB interventions...

REVIEW
Peter Bommert, Clinton Whipple
The grass inflorescence is striking not only for its beauty and diversity, but also for its developmental complexity. While models of inflorescence architecture have been proposed in both eudicots and grasses, these are inadequate to fully explain the complex branching events that occur during the development of the grass inflorescence. Key to understanding grass inflorescence architecture is the meristem determinacy/indeterminacy decision, which regulates the number of branching events that occur. Here we review what has been learned about meristem determinacy from grass mutants with defects in inflorescence development...

OBJECTIVE: The tumors of the head of the pancreas are one of the leading causes of cancer-related death in Western countries. The current gold standard for these tumors is a Whipple procedure. This procedure did not change in its surgical steps since when it was initially introduced in 1935. More recently, a laparoscopic approach with similar outcomes has been described. The aim of this paper is to describe the laparoscopic surgical technique performed in our unit, reporting single center postoperative outcomes...

Plant genetic variation and soil microorganisms are individually known to influence plant responses to climate change, but the interactive effects of these two factors are largely unknown. Using long-term observational studies in the field and common garden and greenhouse experiments of a foundation tree species (Pinus edulis) and its mutualistic ectomycorrhizal fungal (EMF) associates, we show that EMF community composition is under strong plant genetic control. Seedlings acquire the EMF community of their seed source trees (drought tolerant vs...

The prognosis of pancreatic cancer remains poor, even after initial surgical therapy. Local recurrence after Whipple's pancreatico-duodenectomy may lead to intestinal obstruction at the level of the afferent limb or the alimentary limb. Endoscopic insertion of a self-expandable metal stent (SEMS) into the intestinal malignant stricture is the preferred method of choice for palliation. We describe two new endoscopic techniques to treat a malignant intestinal obstruction with the insertion of a SEMS into the afferent limb and the alimentary limb...

Whipple's disease is an infection caused by the Gram-positive bacillus Tropheryma whipplei. Invasion or uptake of the bacteria can occur in various parts of the body. The differential diagnoses are broad due to the wide spectrum of infection, and the disease is diagnosed based on biopsy of suspected lesions, usually in the small intestine. We present the case of a 56-year-old man with no significant prior medical history who presented with swelling and pain in the left eye. Review of systems revealed 6 months of persistent diarrhea, and intestinal biopsy revealed periodic acid-Schiff-positive macrophages...

Whipple's disease can mimic spondyloarthritis (SpA) or rheumatoid arthritis (RA) for many years and, in a few cases, induces the development of antibodies to cyclic citrullinated peptides. The causative agent Tropheryma whipplei can smolder within cells, including macrophages, by suppressing the xenophagic process, a type of selective autophagy that targets pathogens. Other inflammatory joint diseases may also stem from impaired xenophagy with persistence of bacteria or viruses that can eventually migrate from the mucous membranes to the joints and entheses, where they may exert adverse effects on immune responses, even if they fail to replicate...

OBJECTIVES: A kidney transplant recipient with recurrent pleuritis underwent an open lung biopsy, the results of which revealed multiple nodular infiltrates. Grocott and periodic acid-Schiff staining were positive. Fungal and Tropheryma whipplei PCR were, however, negative. Further identification was needed. METHODS: Formalin-fixed, paraffin-embedded (FFPE) extraction was performed using an FFPE extraction kit. T. whipplei was searched for using a real-time PCR targeting the noncoding repeat specific for T...

Groove pancreatitis (GP) is a rare type of chronic pancreatitis, which primarily affects the groove area of the pancreatic head. Surgery is considered as the ultimate method for GP if the symptoms are not improved by conservative or endoscopic treatments, and the Whipple technique is the common choice at present. The present study introduces a novel surgical procedure for GP, namely groove resection of pancreatic head (GRPH), in a 56-year-old male patient. To the best of our knowledge, this is the first report on GRPH for the surgical treatment of GP...

Whipple's pancreaticoduodenectomy has been refined over the years to be a safe operation though the morbidity rate still remains high (30-50%). Pancreatic fistula is the most important cause of mortality following pancreaticoduodenectomy. To prevent it, surgeons have used two anastomotic techniques: pancreaticojejunostomy and pancreaticogastrostomy. Recent studies found that pancreaticogastrostomy is associated with fewer overall complications than pancreaticojejunostomy. This is a retrospective review of patients who underwent Whipple's at Aga Khan University Hospital and had pancreaticogastrostomy as a preferred anastomosis for pancreatic stump...
