Describe etiologies and trends in non-battle deaths (NBD) among deployed U.S. service members to identify areas for prevention.

Injuries in combat are categorized as battle (result of hostile action) or non-battle related. Previous work found that one-third of injured US military personnel in Iraq and Afghanistan had non-battle injuries (NBI) and emphasized prevention. NBD have not yet been characterized.

U.S. military casualty data for Iraq and Afghanistan from 2001-2014 were obtained from the Defense Casualty Analysis System (DCAS) and the Department of Defense Trauma Registry (DoDTR). Two databases were used because DoDTR does not capture pre-hospital deaths, while DCAS does not contain clinical details. NBI and NBD were identified, etiologies classified, and NBD trends were assessed using a weighted moving average and time-series analysis with autoregressive integrated moving average. Future NBD rates were forecast.

DCAS recorded 59,799 casualties; 21.0% (n=1,431) of all deaths (n=6,745) were NBD. safety strategies.

Pig-to-primate renal xenotransplantation is plagued by early antibody-mediated graft loss which precludes clinical application of renal xenotransplantation. We evaluated whether temporary complement inhibition with anti-C5 antibody Tesidolumab could minimize the impact of early antibody-mediated rejection in rhesus monkeys receiving pig kidneys receiving costimulatory blockade-based immunosuppression.

Double (Gal and Sda) and triple xenoantigen (Gal, Sda, and SLA I) pigs were created using CRISPR/Cas. Kidneys from DKO and TKO pigs were transplanted into rhesus monkeys that had the least reactive crossmatches. Recipients received anti-C5 antibody weekly for 70 days, and T cell depletion, anti-CD154, mycophenolic acid, and steroids as baseline immunosuppression (n = 7). Control recipients did not receive anti-C5 therapy (n = 10).

Temporary anti-C5 therapy reduced early graft loss secondary to antibody-mediated rejection and improved graft survival (P < 0.01). Deleting class I MHC (SLA I) in donor pigs did not ameliorate early antibody-mediated rejection (table). Anti-C5 therapy did not allow for the use of tacrolimus instead of anti-CD154 (table), prolonging survival to a maximum of 62 days.

To estimate the association between estimated glomerular filtration rate (eGFR) and acute myocardial infarction (AMI) or death after ambulatory non-cardiac surgery.

People with chronic kidney disease (CKD) commonly undergo surgical procedures. While most are performed in an ambulatory setting, the risk of major perioperative outcomes after ambulatory surgery for people with CKD is unknown.

In this retrospective population-based cohort study using administrative health data from Alberta, Canada, we included adults with measured preoperative kidney function undergoing ambulatory non-cardiac surgery between April 1 2005 and February 28 2017. Participants were categorized into six eGFR categories (in mL/min/1.73m2) of ≥ 60 (G1-2), 45-59 (G3a), 30-44 (G3b), 15-29 (G4), < 15 not receiving dialysis (G5ND), and those receiving chronic dialysis (G5D). The odds of AMI or death within 30 days of surgery were estimated using multivariable generalized estimating equation models.

We identified 543,160 procedures in 323,521 people with a median age of 66 years (IQR 56-76); 52% were female. Overall, 2,338 people (0.7%) died or had an AMI within 30 days of surgery. Compared with the G1-2 category, the adjusted odds ratio of death or AMI increased from 1.1 (95% Confidence interval [CI] 1.0, 1.3) for G3a to 3.1 (2.6, 3.6) for G5D. Emergency Department and Urgent Care Center visits within 30 days were frequent (17%), though similar across eGFR categories.

Ambulatory surgery was associated with a low risk of major postoperative events. This risk was higher for people with CKD, which may inform their perioperative shared decision-making and management.

Select patients with anatomically favorable walled off pancreatic necrosis may be treated by endoscopic (Endo-TGD) or operative (OR-TGD) transgastric debridement (TGD). We compared our experience with these 2 approaches.

Select necrotizing pancreatitis (NP) patients are suitable for TGD which may be accomplished endoscopically or surgically. Limited experience exists contrasting these techniques exists.

Patients undergoing Endo-TGD and OR-TGD at a single, high-volume pancreatic center between 2008 and 2019 were identified from a prospective database. Patient characteristics, procedural details, and outcomes of these 2 groups were compared.

Among 498 NP patients undergoing necrosis intervention, 160 (32%) had TGD 59 Endo-TGD and 101 OR-TGD. The groups were statistically similar in age, comorbidity, pancreatitis etiology, necrosis anatomy, pancreatitis severity, and timing of TGD from pancreatitis insult. OR-TGD required 1.1 ± 0.5 and Endo-TGD 3.0 ± 2.0 debridements/patient. Fewer hospital readmissions and repeat necrosis interventions, and shorter total inpatient length of stay were observed in OR-TGD patients. New-onset organ failure [Endo-TGD (13%); OR-TGD (13%); P = 1.0] was similar between groups. Hospital length of stay after TGD was significantly longer in patients undergoing Endo-TGD (13.8 ± 20.8 days) compared to OR-TGD (9.4 ± 6.1 days; P = 0.047). Mortality was 7% in Endo-TGD and 1% in OR-TGD (P = 0.04).

Operative and endoscopic transgastric debridement achieve necrosis resolution with different temporal and procedural profiles. Clear multidisciplinary communication is essential to determine appropriate approach to individual necrotizing pancreatitis patients.

A 59-year-old woman with lobular breast cancer was referred to nuclear medicine department for a 68Ga-FAPI PET/CT study after completion of treatment to rule out the possibility of metastatic disease. It revealed a lytic lesion showing increased FAPI accumulation in the right acetabulum, highly suspicious for bone metastasis. In comparison to an initial 18F-FDG PET/CT study done 2 years before, the lytic lesion showing no FDG uptake in the right acetabulum remained unchanged, and the findings were consistent with bone cyst. This case highlighted that benign bone cyst may demonstrate increased 68Ga-FAPI uptake mimicking bone metastasis on 68Ga-FAPI PET/CT.

Diffuse peritoneal and omental infiltration of prostate cancer detected by 18F-PSMA-1007 PET/CT was rarely reported. We report a case of an 80-year-old man who was suspected of prostate carcinoma metastasis and underwent 18F-PSMA-1007 PET/CT for restaging the disease. PET/CT imaging presented intense tracer uptake in the prostate gland, multiple lymph nodes, and bones. Interestingly, we found extremely increased radioactive uptake of diffuse peritoneum and omentum on 18F-PSMA-1007 PET/CT images, which are very rare metastatic sites for prostate cancer.

Osteoblastoma is an uncommon benign osteoid tissue-forming bone tumor. We present the case of a 16-year-old adolescent boy with lower back pain that radiated down the right thigh. Lumbar MRI and CT findings were consistent with a long-standing osteoid osteoma located in the right laminae and pedicle of L3. SPECT/CT with 99mTc-DPD showed a highly increased osteogenic activity within the lesion, especially in the core region, also suggesting an osteoid osteoma. Surgical en bloc resection was performed with a final histological diagnosis of osteoblastoma.

Inflammatory myofibroblastic tumor is an uncommon mesenchymal neoplasm, which can be seen in any anatomic region from the central nervous system to the gastrointestinal tract. Herein, we report the 68Ga-FAPI PET/CT findings in a 49-year-old man with mesenteric inflammatory myofibroblastic tumor.

A 26-year-old man presented with recurrent oral ulcer, temporal headache, and blurred vision for 4 months. The giant cell arteritis was suspected, and 18F-FDG and 68Ga-FAPI PET/CT were done. There was no hypermetabolic lesion in 18F-FDG PET/CT. However, 68Ga-FAPI PET/CT showed multiple increased FAPI uptake lesions in the cerebral venous sinus. High-resolution MR venography revealed multiple chronic cerebral venous sinus thrombosis. Neuro-Behçet disease was diagnosed finally. This case showed 68Ga-FAPI PET/CT may play some role in the management of neuro-Behçet disease.
