RESUMEN

BACKGROUND: Eating patterns such as breakfast consumption and fruit and vegetable intake have been associated with academic achievement and cognitive function. METHOD: The purpose of this study was to learn more about psychological (emotion-driven eating) and behavioral (over-eating) eating patterns and motives, and the roles of body image, academic achievement (reading and math), and social supports (peer acceptance and school attachment), among 378 fourth-grade students (55% boys) from 14 classrooms across 6 schools within a large Midwestern urban area. RESULTS: Results were analyzed through a 2-group (male and female) path analysis. Boys' overeating (R2 = 9%) was not significantly predicted. Their emotional eating (R2 = 22.2%) was negatively, significantly predicted by peer acceptance and interaction of peer acceptance and school attachment. Girls' overeating (R2 = 13.6%) was negatively, significantly predicted by positive body image. Girls' emotional eating (R2 = 24.1%) was negatively significantly predicted by positive body image, math scores, and peer acceptance. CONCLUSIONS: Boys' and girls' eating patterns are differentially affected by their school experiences.

RESUMEN

OBJECTIVE: Dose de-escalation of adjuvant therapy (DART) in patients with HPV(+)OPSCC was investigated in two prospective Phase II and III clinical trials (MC1273 and MC1675). We report the 30-day morbidity and mortality associated with primary TORS resection in patients enrolled in these trials. MATERIALS AND METHODS: Patients with HPV(+)OPSCC, who underwent TORS resection between 2013 and 2020 were considered in this analysis. The severity of postoperative transoral bleeding was graded using both the Hinni Grade (HG) transoral surgery bleeding scale and the Common Terminology for Adverse Events (CTCAE) v5.0. Post-surgical complications within 30 days of surgery, as well as rates of tracheostomy, PEG and nasogastric tube placement. RESULTS: 219 patients were included. A total of 7 (3.2 %) patients had a tracheostomy placed at the time of surgery, and all were decannulated within 26 days (median: 5, range: 2-26). There were 33 (15.1 %) returns to the emergency department (ED) with 10 (4.6 %) patients requiring readmission. Using the HG scale, 10 (4.6 %) patients experienced ≥ Grade 3 bleeding with no Grade 5 or 6 bleeds. In contrast, using the CTCAE scale, 15 patients (6.8 %) experienced ≥ Grade 3 bleeding with no Grade 5 bleeds. There was one post-operative death in a patient withdrawn from the trial, and no deaths related to hemorrhage. CONCLUSION AND RELEVANCE: TORS for HPV(+)OPSCC in carefully selected patients at a high volume center was associated with low morbidity and mortality.

RESUMEN

INTRODUCTION: A wandering spleen occurs when laxity or absence of the suspensory ligaments allows migration throughout the abdomen. Gastric outlet obstruction resulting from this abnormality is rare. We present a systematic literature search and a case that was managed successfully with surgical intervention at our centre. METHODS: A systematic search of the PubMed, Embase™, Medline® and Google Scholar™ databases was carried out employing the combined search terms "gastric outlet obstruction" AND "wandering spleen". Six results were included for final analysis. RESULTS: All six search results described a single case each. Patients underwent surgical management (open or laparoscopic) after initial investigation utilising a range of modalities. There were no mortalities reported at 90 days. The single case we present was complicated by gastric perforation; the patient made a successful recovery following open splenopexy and stapled wedge resection of the stomach. CONCLUSIONS: A wandering spleen is a rare diagnosis and there are only six reported cases of gastric outlet obstruction secondary to a wandering spleen in the literature. None report associated gastric perforation. There are a variety of presenting symptoms, intraoperative findings and operative techniques used to address the gastrosplenic abnormality. The case reported by our centre adds to this limited evidence base and demonstrates a successful outcome from definitive surgical management. We highlight the need to seek early gastro-oesophageal expertise if any gastric pathology is found together with anatomical abnormality of the spleen.

RESUMEN

OBJECTIVES: To identify and describe the type and frequency of perioperative factors in dogs and cats undergoing pancreatic surgery under referral care. METHODS: Medical records from a small animal surgical referral practice were retrospectively reviewed to identify dogs and cats that underwent pancreatic surgery between 2008 and 2019. Inclusion criteria included complete medical record, histopathology results and follow-up of at least 14 days postoperatively or until death. Variables collected included signalment, history, presenting complaint, preoperative diagnostic results, intraoperative complications, surgical findings/procedures, postoperative complications and histopathology results. Cases were excluded if pertinent information or a histopathology report was missing from the medical record. The frequency of these variables was reported. RESULTS: There were 81 client-owned animals identified that met the inclusion criteria (57 dogs and 24 cats). The most common pancreatic procedure performed in dogs was partial pancreatectomy 63.2% (36/57) and in cats was pancreatic biopsy 62.5% (15/24). The most common histologic diagnosis in dogs was pancreatic islet cell carcinoma 50.9% (29/57) and in cats was pancreatitis 41.7% (10/24). The overall mortality rate was 13.6% (11/81), with a 10.5% (6/57) mortality rate in dogs and a 20.8% (5/24) mortality rate in cats. CLINICAL SIGNIFICANCE: In this series of dogs and cats, pancreatic surgery under referral care carried a low to moderate mortality rate.

RESUMEN

The pathophysiology after polytrauma represents a complex network of interactions. While it was thought for a long time that the direct and indirect effects of hypoperfusion are most relevant due to the endothelial permeability changes, it was discovered that the innate immune response to trauma is equally important in modifying the organ response. Recent multi center studies provided a "genetic storm" theory, according to which certain neutrophil changes are activated at the time of injury. However, a second hit phenomenon can be induced by activation of certain molecules by direct organ injury, or pathogens (damage associated molecular patterns, DAMPS - pathogen associated molecular patterns, PAMPS). The interactions between the four pathogenetic cycles (of shock, coagulopathy, temperature loss and soft tissue injuries) and cross-talk between coagulation and inflammation have also been identified as important modifiers of the clinical status. In a similar fashion, overzealous surgeries and their associated soft tissue injury and blood loss can induce secondary worsening of the patient condition. Therefore, staged surgeries in certain indications represent an important alternative, to allow for performing a "safe definitive surgery" strategy for major fractures. The current review summarizes all these situations in a detailed fashion.

RESUMEN

OBJECTIVE: To investigate associations between multimodal analgesia and post-operative pain among patients undergoing transoral robotic surgery for oropharyngeal squamous cell carcinoma. METHODS: Records of patients who underwent surgery from 5 September 2012 to 30 November 2016 were abstracted. Associations were assessed using multivariable analysis. RESULTS: A total of 216 patients (mean age of 59.1 years, 89.4 per cent male) underwent transoral robotic surgery (92.6 per cent were human papilloma virus positive, 87.5 per cent had stage T1-T2 tumours, and 82.9 per cent had stage N0-N1 nodes). Gabapentin (n = 86) was not associated with a reduction in severe pain. Ibuprofen (n = 72) was administered less often in patients with severe pain. Gabapentin was not associated with increased post-operative sedation (p = 0.624) and ibuprofen was not associated with increased bleeding (p = 0.221). Post-operative opioid usage was not associated with surgical duration, pharyngotomy, bilateral neck dissections, tumour stage, tumour size, subsite or gabapentin. CONCLUSION: Scheduled low-dose gabapentin was not associated with improved pain control or increased respiratory depression. Ibuprofen was not associated with an increased risk of bleeding and may be under-utilised.

RESUMEN

For the first time, a simple and robust HPLC method has been developed for dissolution studies for cannabidiol (CBD) in hemp oil products. An isocratic elution of samples performed on SOLAS™ C18 150 mm x 4.6 mm, 5 µm column with a mobile phase consisting of 75:25 acetonitrile-water v/v, delivered at a flow rate 1.5 mL/minutes to variable wavelength detector using 214 nm. An in-house validated assay test was executed for calculating the purity of hemp oil products and also for considering the dissolution medium to be used. For dissolution studies, equivalent of 5 mg and/or 10 mg of the active was introduced into 500 mL of simulated gastric and intestinal fluids separately, and dissolution was performed at 50 rpm using paddles for 180 min. Dissolution profiles for hemp oil products purchased from the United States and Europe were compared. Additionally, dissolution testing was conducted to study the effect of percentage CBD release on increased agitation speed of 75 and 100 rpm and also, on extended dissolution runtime of 240 min.

RESUMEN

BACKGROUND: QTc interval (QTc) prolongation is seen on the post-arrest electrocardiogram (ECG) of many out of hospital cardiac arrest (OHCA) survivors. It remains unclear whether this is a transient phenomenon or a manifestation of an underlying arrhythmic substrate. This observational study assessed the trend of QTc in an unselected group of patients presenting with OHCA. We sought to identify any relationship between QTc, gender and aetiology of arrest. We observed whether targeted temperature management (TTM) is associated with malignant arrhythmia. METHOD: We analysed 60 patients presenting with OHCA to the Bristol Heart Institute during a 20-month period. We measured QTc on admission and assessed for persistence, development and resolution of prolongation at up to 5 time points post-OHCA. Aetiology of arrest was divided into coronary, non-coronary or primary arrhythmic to investigate for patterns in QTc behaviour. RESULTS: 81.7% (49/60) of arrests were attributed to an acute coronary event. 55% (33/60) had QTc prolongation on admission, of which 79% resolved. There were no significant differences in QTc behaviour by aetiology. One patient presenting with a normal QTc, developed prolongation during admission and received a genetic diagnosis of Long QT Syndrome. TTM was employed in 57/60, with no increased incidence of malignant arrhythmia. CONCLUSIONS: Prolonged QTc on admission does not imply a primary arrhythmic aetiology and resolves in the majority pre-discharge. However, an initial normal QTc post-OHCA does not preclude a diagnosis of Long QT syndrome, highlighting the importance of thorough investigations in these patients. TTM appears safe from a cardiac perspective.

RESUMEN

INTRODUCTION: Current procedural terminology (CPT) codes for surgical stabilization of rib fractures (SSRF) are based solely on the number of ribs fixed, tricotomized at 1-3, 4-6, and ≥ 7. Our objective was to validate CPT codes against operative time at our institution, as well as further stratify complexity by rib fracture location and surgical approach. The purpose of this study is to validate the current CPT coding schema for SSRF, and to identify potential modifiers that are associated with increased case complexity. We hypothesized that operative time is associated with CPT code, number of fractures repaired, exposure technique, and fracture location. METHODS: Retrospective review of SSRF cases from October 2010 to March 2020. The primary outcome was the length of the operation (minutes). Predictor variables were CPT code, number of fractures repaired (grouped similarly to CPT codes), fractures repaired:ribs repaired ratio > 1, fracture location (sub-scapular vs. other), and positioning/exposure (supine, lateral, prone, and multiple). Kaplan-Meier time-to-event analyses were used to assess relationship with operative time. RESULTS: 188 patients underwent repair of 904 fractures. Operative time was significantly associated with both number of ribs repaired and number of fractures repaired (p<0.01). Although operative time varied significantly by CPT group (p<0.01), there was no significant difference between the 4-6 rib and the ≥ 7 rib groups (p = 0.33). By contrast, each group was significantly different from the others when organized by number of fractures repaired (p = 0.04). Operative time was significantly longer when the fractures repaired:ribs repaired ratio was > 1 (p<0.01), even after stratifying by number of ribs repaired. Both multiple positions/exposures (p<0.01), and repair of ≥ 1 sub-scapular fracture (p<0.01) were significantly associated with operative time. CONCLUSION: Number of fractures repaired provided a more accurate estimation of operative time as compared to number of ribs repaired. Based on these data, we recommend altering the CPT schema for SSRF to involve number of fractures repaired, with modifiers for both multiple positions/exposures and repair of sub-scapular fractures.

RESUMEN

BACKGROUND: Many women with hyperglycaemia in pregnancy do not receive care during and after pregnancy according to standards recommended in international guidelines. The burden of hyperglycaemia in pregnancy falls disproportionately upon Indigenous peoples worldwide, including Aboriginal and Torres Strait Islander women in Australia. The remote and regional Australian context poses additional barriers to delivering healthcare, including high staff turnover and a socially disadvantaged population with a high prevalence of diabetes. METHODS: A complex health systems intervention to improve care for women during and after a pregnancy complicated by hyperglycaemia will be implemented in remote and regional Australia (the Northern Territory and Far North Queensland). The Theoretical Domains Framework was used during formative work with stakeholders to identify intervention components: (1) increasing workforce capacity, skills and knowledge and improving health literacy of health professionals and women; (2) improving access to healthcare through culturally and clinically appropriate pathways; (3) improving information management and communication; (4) enhancing policies and guidelines; (5) embedding use of a clinical register as a quality improvement tool. The intervention will be evaluated utilising the RE-AIM framework at two timepoints: firstly, a qualitative interim evaluation involving interviews with stakeholders (health professionals, champions and project implementers); and subsequently a mixed-methods final evaluation of outcomes and processes: interviews with stakeholders; survey of health professionals; an audit of electronic health records and clinical register; and a review of operational documents. Outcome measures include changes between pre- and post-intervention in: proportion of high risk women receiving recommended glucose screening in early pregnancy; diabetes-related birth outcomes; proportion of women receiving recommended postpartum care including glucose testing; health practitioner confidence in providing care, knowledge and use of relevant guidelines and referral pathways, and perception of care coordination and communication systems; changes to health systems including referral pathways and clinical guidelines. DISCUSSION: This study will provide insights into the impact of health systems changes in improving care for women with hyperglycaemia during and after pregnancy in a challenging setting. It will also provide detailed information on process measures in the implementation of such health system changes.

RESUMEN

BACKGROUND: National surveillance of Clostridium difficile infection (CDI) in Scotland enables the monitoring of trends in incidence rates but not mortality. AIM: To assess factors associated with mortality for all CDI cases aged ≥15 years in Scotland between 2010 and 2016. METHODS: All CDI cases aged ≥15 years in Scotland between 2010 and 2016 were linked to hospital admission and mortality datasets. Logistic regression was used to assess factors associated with mortality (30-day all-cause). A case-control study of a hospitalized subset of cases and matched hospitalized controls assessed the impact of CDI on mortality and length of stay. FINDINGS: Thirty-day all-cause mortality decreased over the seven-year period (from 20.5% to 15.6%; P < 0.001), mainly among healthcare-associated CDI (HA-CDI). Increased age, higher Charlson score, HA-CDI, as well as liver, heart and malignancy comorbidities were associated with higher mortality. No association was observed between polymerase chain reaction ribotype and higher mortality, though 015 and 078 were associated with lower mortality. Adjusted odds ratio (OR) for 30-day mortality in hospitalized CDI cases compared to controls was 2.67 (95% confidence interval (CI): 2.42-2.94; P < 0.001). Whereas mortality declined over time in cases and controls, the trend in ORs remained relatively stable. Having CDI increased additional mean length of stay beyond infection by 22.3% (95% CI: 18.0-26.8%; P < 0.001). CONCLUSION: CDI is associated with an almost three-fold increase in 30-day mortality and places an increased burden on hospital resources by increasing mean LOS beyond the infection date by 22.3%. The decreasing CDI mortality trends may be due to overall improvements in mortality among the general and hospital population of Scotland. Therefore, despite large declines in incidence rates, CDI remains a serious healthcare problem.

RESUMEN

The aim of this study was to evaluate the effects of a low dose dexmedetomidine constant rate infusion (CRI) on cardiopulmonary function, inhalant anesthetic concentration and recovery in isoflurane anesthetized cats. In a prospective, randomized, blinded, controlled design, 12 cats undergoing anesthesia for ovariohysterectomy were administered hydromorphone (0.1mg/kg) intramuscularly, propofol (4.3-7.8mg/kg) intravenously and maintained with isoflurane. During isoflurane anesthesia, the cats were administered either a dexmedetomidine loading dose (0.5µg/kg) followed by a dexmedetomidine CRI (0.5µg/kg/h) (group LDD), or a saline loading dose followed by a saline CRI (group SAL). Heart rate (HR), respiratory rate, blood pressure, temperature, oxygen saturation (SpO2), end tidal carbon dioxide concentration (ETCO2), end tidal isoflurane concentration (ETISO) and anesthetic depth were recorded at nine time points (T0-T8). Overall effects (T1-8) and individual time point results were compared between groups. There were no significant differences in baseline variables (T0), age, weight, propofol dose, anesthesia and surgery time, time to extubation or recovery score between groups. Among the physiological variables measured, significant differences were observed in respiratory rate, ETCO2, and mean and diastolic blood pressure, between groups at individual time points. Systolic blood pressure, HR, SpO2, ETISO and temperature were not significantly different between groups at individual time points. Overall, ETCO2 and ETISO were significantly lower and respiratory rate was significantly higher for LDD compared to SAL. At the doses administered, a CRI of dexmedetomidine reduced isoflurane requirements in anesthetized cats undergoing ovariohysterectomy. The utility of a low dose dexmedetomidine CRI in the perioperative setting requires further investigation, since intraoperative cardiopulmonary values during dexmedetomidine infusion were not different from those receiving saline.

RESUMEN

The goals of this retrospective study were to determine the patient characteristics of dogs with high-grade primary mediastinal lymphoma and to determine outcome and associated prognostic factors. A total of 42 dogs were identified, in which 36 received treatment and had follow-up information available. The most common clinical signs included lethargy, anorexia and polyuria/polydipsia. Hypercalcemia and pleural effusion were common findings at diagnosis. The phenotype was almost exclusively T-cell, most often in association with lymphoblastic cytomorphology as defined by the World Health Organization (WHO) lymphoma classification scheme. The overall progression-free survival (PFS) and overall survival (OS) were 133 and 183 days, respectively. Treatment with a CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) protocol was associated with an improved PFS (144 days) and OS (194 days) when compared with dogs that received other medical therapies (P = .005 and P = .002, respectively); the absence of pleural effusion at diagnosis was associated with an increased OS but not PFS. These results suggest that while the prognosis for dogs with mediastinal lymphoma is poor, survival may be improved with treatment using a CHOP-based protocol.

RESUMEN

BACKGROUND: Opportunities to improve emergency surgery outcomes exist through guided better practice and reduced variability. Few attempts have been made to define optimal care in emergency surgery, and few clinically derived key performance indicators (KPIs) have been published. A summit was therefore convened to look at resources for optimal care of emergency surgery. The aim of the Donegal Summit was to set a platform in place to develop guidelines and KPIs in emergency surgery. METHODS: The project had multidisciplinary global involvement in producing consensus statements regarding emergency surgery care in key areas, and to assess feasibility of producing KPIs that could be used to monitor process and outcome of care in the future. RESULTS: Forty-four key opinion leaders in emergency surgery, across 7 disciplines from 17 countries, composed evidence-based position papers on 14 key areas of emergency surgery and 112 KPIs in 20 acute conditions or emergency systems. CONCLUSIONS: The summit was successful in achieving position papers and KPIs in emergency surgery. While position papers were limited by non-graded evidence and non-validated KPIs, the process set a foundation for the future advancement of emergency surgery.

RESUMEN

OBJECTIVE: The rapid worldwide rise in incidence of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has generated studies confirming this disease as an entity distinct from traditional OPSCC. Based on pathology, surgical studies have revealed prognosticators specific to HPV-positive OPSCC. The current AJCC/UICC staging and pathologic nodal (pN)-classification do not differentiate for survival, demonstrating the need for new, HPV-specific OPSCC staging. The objective of this study was to define a pathologic staging system specific to HPV-positive OPSCC. METHODS: Data were assembled from a surgically-managed, p16-positive OPSCC cohort (any T, any N, M0) of 704 patients from five cancer centers. Analysis was performed for (a) the AJCC/UICC pathologic staging, (b) newly published clinical staging for non-surgically managed HPV-positive OPSCC, and (c) a novel, pathology-based, "HPVpath" staging system that combines features of the primary tumor and nodal metastases. RESULTS: A combination of AJCC/UICC pT-classification and pathology-confirmed metastatic node count (⩽4 versus ⩾5) yielded three groups: stages I (pT1-T2, ⩽4 nodes), II (pT1-T2, ⩾5 nodes; pT3-T4, ⩽4 nodes), and III (pT3-T4, ⩾5 nodes), with incrementally worse prognosis (Kaplan-Meier overall survival of 90%, 84% and 48% respectively). Existing AJCC/UICC pathologic staging lacked prognostic definition. Newly published HPV-specific clinical stagings from non-surgically managed patients, although prognostic, showed lower precision for this surgically managed cohort. CONCLUSIONS: Three loco-regional "HPVpath" stages are identifiable for HPV-positive OPSCC, based on a combination of AJCC/UICC primary tumor pT-classification and metastatic node count. A workable, pathologic staging system is feasible to establish prognosis and guide adjuvant therapy decisions in surgically-managed HPV-positive OPSCC.

RESUMEN

BACKGROUND: Systemic hyperfibrinolysis is a lethal phenotype of trauma-induced coagulopathy. Its pathogenesis is poorly understood. Recent studies have support a central role of platelets in hemostasis and in fibrinolysis regulation, implying that platelet impairment is integral to the development of postinjury systemic hyperfibrinolysis. OBJECTIVE: The objective of this study was to identify if platelet function is associated with blood clot sensitivity to fibrinolysis. We hypothesize that platelet impairment of the ADP pathway correlates with fibrinolysis sensitivity in trauma patients. METHODS: A prospective observational study of patients meeting the criteria for the highest level of activation at an urban trauma center was performed. Viscoelastic parameters associated with platelet function (maximum amplitude [MA]) were measured with native thrombelastography (TEG), and TEG platelet mapping of the ADP pathway (ADP-MA). The contribution of fibrinogen to clotting was measured with TEG (angle) and the TEG functional fibrinogen (FF) assay (FF-MA). Another TEG assay containing tissue-type plasminogen activator (t-PA) (75 ng mL(-1) ) was used to assess clot sensitivity to an exogenous fibrinolytic stimulus by use of the TEG lysis at 30 min (LY30) variable. Multivariate linear regression was used to identify which TEG variable correlated with t-PA-LY30 (quantification of fibrinolysis sensitivity). RESULTS: Fifty-eight trauma patients were included in the analysis, with a median injury severity score of 17 and a base deficit of 6 mEq L(-1) . TEG parameters that significantly predicted t-PA-LY30 were related to platelet function (ADP-MA, P = 0.001; MA, P < 0.001) but not to fibrinogen (FF-MA, P = 0.773; angle, P = 0.083). Clinical predictors of platelet ADP impairment included calcium level (P = 0.001), base deficit (P = 0.001), and injury severity (P = 0.001). RESULTS AND CONCLUSIONS: Platelet impairment of the ADP pathway is associated with increased sensitivity to t-PA. ADP pathway inhibition in platelets may be an early step in the pathogenesis of systemic hyperfibrinolysis.
