Amebic Liver Abscess With Intra-Biliary Rupture
The case of a large amebic liver abscess with an atypical presentation is reported. High output bile
drainage persisted after ultrasound guided percutaneous catheter drainage because of a preexisting
communication of the abscess with the right hepatic ductal system. The abscess was managed
successfully by surgical evacuation and internal drainage into a defunctioned jejunal loop
Non-Hodgkin's lymphoma: Is India ready to incorporate recent advances in day to day practice?
Background : Non Hodgkin\u2032s Lymphoma (NHL) cure rates are
increasing and morbidities are decreasing, with more active
pharmacological agents and technological advancements. In spite of
this, India is still battling with the prejudices of an economically
and educationally impoverished patient base. Methods and Results : We
analyzed NHL cases from 2000 to 2006 using data from case sheets. Of
303 cases, only 100 patients had complete workup and received some form
of treatment. For 203 patients, reasons for non-compliance were:
financial constraint (119), distance from center (38), inability of
physician to provide guarantees of cure (13), poor prognosis/fear of
recurrence (28)), preferences for alternate medicine (5). Most common
investigations that could not be afforded for staging were whole body
CT scans and bone marrow aspiration and biopsy. Thirteen patients were
in stage III and 53 in Stage IV. The most common regimen was CHOP
(Cyclophosphamide, Adriamycin, Vincristine, Prednisolone). Forty-five
patients did not complete six courses of CHOP and 35 patients had
significant delay. Reasons for delay were intermittent availability of
cash (35), intolerable toxicities (30), absence of supportive care
(21), given-up attitudes (17). Eighty-three patients suffered Grade
III/IV debilitating toxicities. Overall survival at five years was 50%.
Conclusions : NHL in India is no different from the developed world.
However, there are disparities in survivorship and outcomes, due to
un-affordability and attitudes of the patients. Therefore, we suggest
the development of Community Health Insurance Schemes (CHIs), with the
hospital as the nodal center to address the above mentioned issues
HaplĂłs: Vibrotactile somaesthetic technology for body awareness
Inspired by somatic methodologies and neurophysiology, HaplĂłs is a low-cost, wearable technology that applies vibrotactile patterns to the skin, can be incorporated in existing clothing and implements, and can be programmed and activated remotely. We review existing vibrotactile technologies and known uses of vibrotactile stimuli; describe the hardware, textile, and software components of HaplĂłs; describe results from a quasi-experimental workshop to evaluate HaplĂłs; and discuss future research and development directions
Prevention of febrile neutropenia: use of prophylactic antibiotics
Febrile neutropenia (FN) causes significant morbidity and mortality in patients receiving cytotoxic chemotherapy and can lead to reduced chemotherapy dose intensity and increased overall treatment costs. Antibiotic prophylaxis reduces the incidence of FN. Recent research and meta-analyses confirm that prophylactic fluoroquinolones decrease FN and infection-related mortality in patients with acute leukaemia and those receiving high-dose chemotherapy. Fluoroquinolone prophylaxis also lowers the incidence of FN and all-cause mortality following the first cycle of myelosuppressive chemotherapy for solid tumours. Levofloxacin has been the agent studied most thoroughly in this context. Although there is no convincing evidence that colonisation of individuals with resistant organisms due to antibiotic prophylaxis increases FN or mortality, such concerns must be taken seriously and the use of prophylaxis should be limited responsibly for patients with the greatest chance of benefit. Fluoroquinolone prophylaxis is well tolerated and cost-effective and should be offered to patients receiving chemotherapy for haematological malignancies and high-dose chemotherapy for solid tumours in which prolonged (>7 days) neutropenia is expected. It should also be considered for those receiving chemotherapy for solid tumours and lymphomas during the first cycle of chemotherapy when grade 4 neutropenia is anticipated
Open X-Embodiment:Robotic learning datasets and RT-X models
Large, high-capacity models trained on diverse datasets have shown remarkable successes on efficiently tackling downstream applications. In domains from NLP to Computer Vision, this has led to a consolidation of pretrained models, with general pretrained backbones serving as a starting point for many applications. Can such a consolidation happen in robotics? Conventionally, robotic learning methods train a separate model for every application, every robot, and even every environment. Can we instead train "generalist" X-robot policy that can be adapted efficiently to new robots, tasks, and environments? In this paper, we provide datasets in standardized data formats and models to make it possible to explore this possibility in the context of robotic manipulation, alongside experimental results that provide an example of effective X-robot policies. We assemble a dataset from 22 different robots collected through a collaboration between 21 institutions, demonstrating 527 skills (160266 tasks). We show that a high-capacity model trained on this data, which we call RT-X, exhibits positive transfer and improves the capabilities of multiple robots by leveraging experience from other platforms.

Risk of Bowel Obstruction in Patients Undergoing Neoadjuvant Chemotherapy for High-risk Colon Cancer
Objective:
This study aimed to identify risk criteria available before the point of treatment initiation that can be used to stratify the risk of obstruction in patients undergoing neoadjuvant chemotherapy (NAC) for high-risk colon cancer.
Background:
Global implementation of NAC for colon cancer, informed by the FOxTROT trial, may increase the risk of bowel obstruction.
Methods:
A case-control study, nested within an international randomized controlled trial (FOxTROT; ClinicalTrials.gov: NCT00647530). Patients with high-risk operable colon cancer (radiologically staged T3-4 N0-2 M0) that were randomized to NAC and developed large bowel obstruction were identified. First, clinical outcomes were compared between patients receiving NAC in FOxTROT who did and did not develop obstruction. Second, obstructed patients (cases) were age-matched and sex-matched with patients who did not develop obstruction (controls) in a 1:3 ratio using random sampling. Bayesian conditional mixed-effects logistic regression modeling was used to explore clinical, radiologic, and pathologic features associated with obstruction. The absolute risk of obstruction based on the presence or absence of risk criteria was estimated for all patients receiving NAC.
Results:
Of 1053 patients randomized in FOxTROT, 699 received NAC, of whom 30 (4.3%) developed obstruction. Patients underwent care in European hospitals including 88 UK, 7 Danish, and 3 Swedish centers. There was more open surgery (65.4% vs 38.0%, P=0.01) and a higher pR1 rate in obstructed patients (12.0% vs 3.8%, P=0.004), but otherwise comparable postoperative outcomes. In the case-controlâmatched Bayesian model, 2 independent risk criteria were identified: (1) obstructing disease on endoscopy and/or being unable to pass through the tumor [adjusted odds ratio: 9.09, 95% credible interval: 2.34â39.66] and stricturing disease on radiology or endoscopy (odds ratio: 7.18, 95% CI: 1.84â32.34). Three risk groups were defined according to the presence or absence of these criteria: 63.4% (443/698) of patients were at very low risk (10%).
Conclusions:
Safe selection for NAC for colon cancer can be informed by using 2 features that are available before treatment initiation and identifying a small number of patients with a high risk of preoperative obstruction
