Background Geriatric patients with rib fractures are at risk for developing complications and are often admitted to a higher level of care (intensive care units, ICU) based on existing guidelines. Forced vital capacity has been shown to correlate with outcomes in patients with rib fractures. Complete spirometry may quantify pulmonary capacity, predict outcome and potentially assist with admission triage decisions. Methods We prospectively enrolled 86 patients, 60 and over with three or more isolated rib fractures presenting after injury. After informed consent patients were assessed with respect to pain (visual-analog scale), grip strength, forced vital capacity (FVC), forced expiratory volume 1 second (FEV1), and negative inspiratory force (NIF) on hospital days 1, 2, and 3. Outcomes included discharge disposition, length of stay (LOS), pneumonia, intubation, and unplanned ICU admission. Results Mean age was 77.4 (±10.2) and 43 (50.0%) were female. Forty-five patients (55.6%) were discharged home, median LOS was 4 days (IQR 3, 7). Pneumonias (2), unplanned ICU admissions (3) and intubation (1) were infrequent. Spirometry measures including FVC, FEV1, and grip strength predicted discharge to home and FEV1 and pain level on day one moderately correlated with the LOS. Within each subject FVC, FEV1 and NIF did not change over three days despite pain at rest and pain after spirometry improving from day one to three (p=0.002, p less then 0.001 respectively). Change in pain also did not predict outcomes and pain level was not associated with respiratory volumes on any of the three days. After adjustment for confounders FEV1 remained a significant predictor of discharge home (OR 1.03 95% CI [1.01-1.06]) and LOS, p=0.001. Conclusion Spirometry measurements early in the hospital stay predict ultimate discharge home and this may allow immediate or early discharge. The impact of pain control on pulmonary function requires further study. Level of evidence Level IV, diagnostic test.Background Impaired microvascular perfusion in the obese patient has been linked to chronic adverse health consequences. The impact on acute illnesses including trauma, sepsis and hemorrhagic shock (HS) are uncertain. Studies have shown that endothelial glycocalyx and vascular endothelial derangements are causally linked to perfusion abnormalities. Trauma and hemorrhagic shock are also associated with impaired microvascular perfusion in which glycocalyx injury and endothelial dysfunction are sentinel events. We postulate that obesity may impact the adverse consequences of HS on the vascular barrier. This was studied in vivo in a biomimetic model of HS using microfluidic technology. Methods Human umbilical vein endothelial cell (HUVEC) monolayers were established in a microfluidic device. Cells were exposed to standard or biomimetic shock conditions (hypoxia + epinephrine) followed by perfusion from plasma obtained from obese or non-obese subjects. Endothelial glycocalyx and endothelial cellular injury were then determined. Results Plasma from non-obese patients completely reversed glycocalyx and endothelial vascular barrier injury. Plasma from obese patients was only partially protective and was associated with differences in adipokines and other substances in the plasma of these patients. Conclusions Our study supports that obesity impairs hemorrhagic shock resuscitation. This may be due to microrheological differences between non-obese and obese individuals and may contribute to the poorer outcome in this patient population. Level of evidence not applicable (basic-science study).Background Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a viable technique for management of non-compressible torso hemorrhage. The major limitation of the current unilobed fully-occlusive REBOA catheters is below-the-balloon ischemia-reperfusion complications. We hypothesized that partial aortic occlusion with a novel bilobed partial (p)REBOA-PRO would result in the need for less intra-aortic balloon adjustments to maintain a distal goal perfusion pressure as compared to currently available unilobed ER-REBOA. Methods Anesthetized (40-50 kg) swine randomized to control (no intervention), ER-REBOA or pREBOA-PRO underwent supraceliac aortic injury. REBOA groups underwent catheter placement into Zone 1 with initial balloon inflation to full occlusion for 10 minutes followed by gradual deflation to achieve and subsequently maintain half of the baseline below-the-balloon mean arterial pressure (MAP). Physiologic data and blood samples were collected at baseline and then hourly. At 4 hours, flammation. Level of evidence Not applicable, translational randomized animal study.Background Surgical management of trauma in the last twenty years has evolved in parallel with the military's experience in the current conflicts. Therapies such as wide-spread tourniquet use, empiric administration of fresh frozen plasma, and airborne intensive care units had been viewed skeptically, but are now common practice. There is an opportunity to expand the envelope of care even further through similarly innovative approaches and varied avenues of research. Results As the molecular biology of trauma is elucidated, research methodologies must also be developed to capitalize on innovative approaches to resuscitation. Blood component therapy and control of bleeding remain as the fundamental concepts in trauma care. The inflammo-immune response to injury, however, plays an increasingly recognized role in recovery of organ function. Perhaps the inflammatory cascade of trauma can be manipulated to extend the treatment envelope of at risk trauma patients.In trauma, the additional challenge of delivering efombatant. Study type Review LEVEL OF EVIDENCE III.Background Traumatic brain injury (TBI) has significant morbidity and cost implications. Primary treatment modalities aim to decrease intracranial pressure; however, therapies targeting the underlying pathophysiology of a TBI are limited. TBI-induced microvascular leak and secondary injury are largely due to proteolysis of the blood-brain barrier (BBB) by matrix metalloproteinase-9 (MMP-9). We previously observed doxycycline's inhibitory affinity on MMP-9 resulting in preserved BBB integrity in non-survival murine studies. This study sought to determine the effect of doxycycline on functional motor and behavioral outcomes in the setting of a TBI murine survival model. Methods C57BL/6J mice were assigned to a sham, TBI, or TBI with doxycycline arm. A moderate TBI was induced utilizing a controlled cortical impactor. The TBI with doxycycline cohort received a dose of doxycycline (20mg/kg) two hours after injury and every 12 hours until postoperative day (POD)-6. All mice underwent preoperative testing for weight, modified neurological severity score (mNSS), wire grip, and ataxia analysis (DigiGait). Postoperative testing was performed on POD-1, POD-3, and POD-6 for the same measures. SAS 9.4 was used for comparative analysis. Results 15 sham mice, 15 TBI mice, and 10 TBI with doxycycline mice were studied. Mice treated with doxycycline had significantly improved mNSS and wire grip scores at POD-1 (all p less then 0.05). Mice treated with doxycycline had significantly improved ataxia scores by POD-3 and POD-6 (all p less then 0.05). There was no significant difference in rate of weight change between the three groups. Conclusions Mice treated with doxycycline following TBI demonstrated improved behavioral and motor function suggesting doxycycline's role in preserving murine BBB integrity. Examining the role of doxycycline in human TBIs is warranted given the relative universal accessibility, affordability, and safety profile of doxycycline. Level of evidence Animal study.We describe 5 children with severe SARS-CoV-2 infection, hemodynamic instability and suspected acute abdomen. This form of the disease has not been previously documented. Four of the cases were confirmed SARS-CoV-2 infection and 1 probable. All of them were previously healthy and needed a pediatric critical care unit admission. The respiratory symptoms were not dominant or were absent. Also, fever was observed. Laboratory testing revealed lymphopenia and high levels of C-reactive protein and procalcitonin with D-dimer, ferritin and interleukin-6 usually elevated. Respiratory support and inotropic support were almost always necessary. In all of them, deterioration occurred on the day of admission.Background We aimed to determine molecular characteristics of Staphylococcus aureus isolates cultured from hospitalized pediatric patients. Methods All accessible S. aureus isolates cultured from hospitalized pediatric patients were analyzed for staphylococcal cassette chromosome mec (SCCmec) types, Panton-Valentine Leukocidin (PVL) encoding genes and antibiotic resistance patterns. Results A total of 132 S. aureus isolates, 102 methicillin-susceptible S. aureus (MSSA) (81.8%), 30 methicillin-resistant S. aureus (MRSA) (18.2%) were included in the study. Sixty of 132 (45.5%) S. aureus isolates were cultured from skin and soft tissue infections (SSTIs), 50 (37.9%) from bloodstream infections, 11 (8.3%) from bone infections and 11 (8.3%) from other sterile sites. Fifty-three of 102 (52%) MSSA isolates were cultured from SSTI, 35 (34.3%) from bloodstream infections, 7 (6.9%) from bone infections and 7 (6.9%) from other sterile sites (P = 0.083). Fifteen MRSA isolates (50%) were cultured from blood culture, 7 fro hospital acquired. Hospitalization in the past 1 year was found to increase MRSA infections 3.95 times (P = 0.038, 95% confidence interval 1.078-14.48). Conclusions As distribution of virulence genes differs among S. aureus isolates from different regions, it is necessary to monitor the emergence of genes encoding PVL, SCCmec in both MRSA and MSSA throughout the world. Our results show a high prevalence of PVL in community-onset S. aureus infections in children. SCCmec type IV was more commonly isolated in hospital-acquired MRSA isolates, and PVL gene was more commonly isolated in community-acquired S. aureus infections.We describe 3 cases of adolescent varicella-zoster virus reactivation, complicated by aseptic meningitis, presenting to our institution in a 3-year period. These cases highlight varicella-zoster virus reactivation as an important cause of aseptic meningitis in the differential diagnosis of healthy adolescents, even in the absence of a characteristic exanthem. Evidence-based management recommendations are needed.Coronavirus disease 2019 (COVID-19) symptoms in children are incompletely described. We present the first case of orchiepididymitis associated with COVID-19 in a boy and discuss pathways of testicular involvement by SARS-CoV2 virus. This case underlines the need for further study of the clinical presentation of pediatric COVID-19 and the potential association with nonrespiratory symptoms.Purpose To evaluate the long-term outcomes of surgical occlusion of lacrimal puncta using thermal cautery in the management of ocular surface diseases. Methods We reviewed medical records of 80 consecutive patients from a single academic center who underwent punctal cauterization. click here Patient demographics, ocular history, symptoms, and signs of ocular surface diseases pre- and post-cauterization were recorded. Results A total of 80 patients (171 puncta) were included, with an average age of 59 years and a follow-up duration of 27 months. The most common ocular morbidity was ocular graft-versus-host disease (n = 36), followed by primary keratoconjunctivitis sicca (n = 15). Indications for punctal cauterization included plug loss (n = 51), difficulty in plug fitting (n = 11), plug-related complications (n = 6), recanalization of previous cauterization (n = 7), and severe ocular surface disease requiring permanent punctal closure (n = 4). After punctal cauterization, the percentage of eyes with severe (21%) and moderate (25%) dry eye decreased significantly (8% and 19% at 3 months and 6% and 17% at 12 months, P = 0.
