SummaryObjective: To determine the rate of subsequent ‘pivot shift’, meniscal tear and risk factors associated with complications of tibial plateau levelling osteotomy (TPLO) and to assess clinical and owner perception outcome.Study design: Retrospective study.Sample population: Three hundred and forty-eight dogs that had undergone TPLO surgical procedures (n = 476 stifles).Methods: Medical records were reviewed for the retrieval of information on breed, sex, age, body weight, clinical history, radiograph findings, pre- and postoperative tibial plateau angle, limb alignment, unilateral versus bilateral disease, condition of cranial cruciate ligament (CCL) and menisci, implant material, healing time and complications. Clinical and owner-assessed questionnaire outcomes were also recorded.Results: Forty-six (9.7%) postoperative complications were reported. Twenty (4.2%) were classified as major complications requiring an additional surgical intervention, and 26 (5.5%) as minor complications. No risk factors associated with postoperative complications were identified. Ten (2.1%) subsequent meniscal injuries in the stifles with normal unaltered menisci at time of TPLO were reported with a median postoperative time of 9.5 months. Signs of postoperative ‘pivot shift’ were reported in 15 (3.1%) stifles. All stifles with a ‘pivot shift’ had a complete CCL rupture or a debrided partial CCL rupture a medial menisectomy was identified as a risk factor for a ‘pivot shift’ (p = 0.02). Dogs with intact medial meniscus had a significantly higher activity level (p <0.0001) and a shorter time to peak function (p = 0.02) than dogs that underwent menisectomy according to an owner questionnaire.Conclusions: Dogs with TPLO and intact meniscus seemed to have a better and faster recovery than dogs with TPLO and menisectomy based on owner questionnaires. ‘Pivot shift’ was infrequent after TPLO surgery. All dogs with a ‘pivot shift’ had a complete CCL rupture or a debrided partial CCL rupture and menisectomy was identified as a risk factor for its occurrence.Clinical relevance: Considering the relatively low rate of subsequent meniscal injury after TPLO, systematic medial meniscal release with TPLO may be unnecessary. The ‘pivot shift’ deserved further investigation to completely understand its mechanism, to identify its anatomic components and potential consequences on the stifle joint.

Abstract Background Preoperative malnutrition is an independent risk factor for postoperative complications and survival for gastric cancer (GC) patients. This study aimed to investigate the prevalence of malnutrition and the risk factors associated with the delayed discharge of geriatric patients undergoing gastrectomy. Material and Methods A retrospective study of GC patients (age ≥ 65) who underwent gastrectomy at Zhongshan Hospital from January 2018 to May 2020 was conducted. Clinical data, including demographic information, medical history, surgery-related factors, and perioperative nutritional management were collected and analyzed. Results A total of 783 patients were reviewed. The overall frequency of malnutrition was 31.3% (249/783). The levels of albumin, prealbumin, and hemoglobin were lower in the malnutrition group compared with the well-nourished group. Moreover, 51 (6.5%) patients received preoperative total parenteral nutritional support. All patients received postoperative parenteral nutrition; 194 (77.9%) patients in the malnutrition group received an infusion of carbohydrates with composite amino acid and 55 (22.1%) received total nutrient admixture. No significant difference was found in the duration of postoperative nutrition between the groups (P>0.05). The malnutrition group was associated with a higher rate of surgical site infections (SSIs) (P<0.001). Multivariate cox regression revealed that age >70 years, length of surgery >180 min, and postoperative complications were significant risk factors associated with delayed discharge. Conclusion Malnutrition is relatively common in elderly patients undergoing gastrectomy. Age, length of surgery, and postoperative complications are important risk factors associated with delayed discharge. Elderly GC patients with risk factors urgently require specific attention to shorten hospital stays.

The purpose of this retrospective study was to evaluate the risk factors for short-term postoperative complications in the 8 weeks after unilateral tibial plateau leveling osteotomy (TPLO) for cranial cruciate ligament rupture in small dogs weighing less than 15 kg. Medical records were retrospectively reviewed for 90 dogs weighing <15 kg that underwent medial parapatellar arthrotomy with inspection of the meniscus and TPLO performed by the same surgeon between January 2012 and December 2017. The overall complication rate was 4.44% (4/90 dogs). There were four cases of partial incisional dehiscence, none of which required surgical revision. Complications were significantly more likely in dogs that had undergone placement of a 2.4-mm TPLO plate. Overall, the complication rate was less than that in previous studies of dogs weighing > 15kg. In this study, patients in which 2.4-mm TPLO plates were used were more likely to develop postoperative complications. Dogs weighing <15 kg that underwent TPLO had good short-term outcomes with minimal complications. In our study, the overall complication rate after TPLO in dogs weighing <15 kg is less than that historically reported in heavier dogs. Our data suggests that TPLO is a safe treatment option in small dogs with cranial cruciate ligament rupture.

Abstract BackgroundCoinfections in COVID19 appear to worsen hospitalized patients prognosis.ObjectiveTo describe the characteristics of bacterial and fungal coinfections in patients admitted for COVID19 and to identify the risk factors associated with its occurrence.Patients and MethodsSingle-center retrospective study reviewing medical records of patients with COVID19 diagnosed with bacterial or fungal infection during hospital admission.Results333 patients were analyzed during March 15-May 15, 2020. 16.82% had some coinfection during admission. Coinfections were more frequent in patients with comorbidities (80.36% vs 19.64% p<0.025) and in those ICU admitted (52.46% vs 8.86%, p<0.001). Coinfections were significantly more frequent in patients with neutrophilia>7500 and increased procalcitonin on admission as well as lymphopenia<1500 on day 5. Mortality in patients with coinfection was 26.79% vs 23.47% in non-coinfected (p 0.596). Length of stay was longer in coinfected patients (mean 30.59 vs 13.47, p<0.01). Most frequent microorganisms were Enterococci, Candida spp, Enterobacteriaceae and Pseudomonas spp. 74% of patients received ceftriaxone: 17.34% of those treated had a coinfection compared to 15.48% not treated (p 0.694).ConclusionsOccurrence of coinfections is frequent and prolongs hospital stay without influencing mortality. The presence of comorbidities and ICU stay were identified as the main risk factor for coinfection, while increased neutrophils and procalcitonin at admission and lymphopenia during evolution were the main biological predictors. Enterococcus was the most frequent pathogen. Ceftriaxone use does not protect against appearance of bacterial infections. C. albicans was the most frequently isolated fungus and was associated with prolonged ICU stay.

Abstract Background Antibiotic use is a risk factor for CDI. Few studies have correlated use of prior antibiotics with CDI severity in cancer patients. This study identified clinical and microbiology risk factors associated with severe CDI in patients with cancer. We hypothesized that previous antibiotic exposure and microbiome composition at time of CDI presentation, are risk factors for severe disease in cancer patients. Methods This non-interventional, prospective, single-center cohort study examined patients with cancer who had their first episode or first recurrence of CDI between Oct 27, 2016 and Jul 1, 2019. C. difficile was identified using nucleic acid amplification testing. Multivariate analysis was used to determine significant clinical risk factors for severe CDI as defined in the 2018 IDSA/SHEA guidelines. Alpha, and beta diversities were calculated to measure the average species diversity and the overall microbial composition. Differential abundance analysis and progressive permutation analysis were used to single out the significant microbial features that differed across CDI severity levels. Results Patient (n=200) demographics show mean age of 60 yrs., 53% female, majority White (76%) and non-Hispanic (85%). Prior 90 day metronidazole use (Odds Ratio OR 4.68 [1.47-14.91] p0.009) was a significant risk factor for severe CDI. Other factors included Horn’s Index &gt; 2 (OR 7.75 [1.05-57.35] p0.045), Leukocytosis (OR 1.29 [1.16-1.43] p&lt; 0.001), Neutropenia (OR 6.01 [1.34-26.89] p0.019) and Serum Creatinine &gt;0.95 mg/dL (OR 25.30 [8.08-79.17] p&lt; 0.001). Overall, there were no significant differences in alpha and beta diversity between severity levels. However, when identifying individual microbial features, the high presence of Bacteroides uniformis, Ruminococceae, Citrobacter koseri and Salmonella were associated with protection from severe CDI (p&lt; 0.05). Table 1 - Results of multivariate logistic regression analysis of factors associated with severe CDI Figure 1. Microbiome features identified by progressive permutation analysis as seen in a volcano plot. Conclusion A number of risk factors for severe CDI were identified among this population, including prior 90 day metronidazole use. Also, increased relative abundance of Bacteroides uniformis, Ruminococceae, Citrobacter koseri and Salmonella were linked to protection from severe CDI. Reducing metronidazole use in patients with cancer may help prevent subsequent severe CDI.

Objectives: To report the incidence and risk factors for prolonged hospitalization, discharge to a facility, and postoperative complications in geriatric patients who underwent surgery for patella fracture. Design: Retrospective database review. Setting: The American College of Surgeons—National Surgical Quality Improvement Program (NSQIP) collects data from 600 hospitals across the United States. Patients/Participants: NSQIP patients over 65 years of age with patella fractures. Intervention: Surgical fixation of patella fracture including extensor mechanism repair. Main Outcome Measurements: Prolonged hospitalization, discharge to a facility, and 30-day post-operative complications. Results: 1721 patients were included in the study. The average age was 74.9 years. 358 (20.8%) patients were male. 122 (7.1%) patients had a length of stay greater than 7 days. Factors associated with prolonged length of stay include pre-existing renal failure, need for emergent surgery, and time to surgery greater than 24 hours from admission. 640 patients (37.2%) of patients were discharged to a facility after surgery. Discharge to facility was associated with age >77 years, obesity, anemia, thrombocytopenia, pre-operative SIRS, and CCI > 0.5. Admission from home decreased the odds of discharge to a facility. The most common postoperative complications in this population were unplanned readmission (3.4%), unplanned reoperation (2.7%), surgical site infection (1.1%), mortality (1.0%), venous thromboembolism (0.8%), and wound dehiscence (0.2%). Complication rates increased with anemia and ASA class IV-V. Conclusions: Geriatric patients undergoing operative intervention for patella fractures are at high risk for prolonged hospitalization, discharge to facility, unplanned readmission or reoperation, and surgical site complications in the first 30 days following surgery. This study highlights modifiable and non-modifiable risk factors associated with adverse events. Early recognition of these factors can allow for close monitoring and multidisciplinary intervention in the perioperative period to improve outcomes. Level of Evidence: Prognostic level III.

Background: The purpose of this study was to evaluate rates of distal radioulnar joint (DRUJ) fixation based on location of the radial shaft fracture and risk factors associated with postoperative complications following radial shaft open reduction internal fixation (ORIF). Methods: Adult patients who underwent isolated radial shaft ORIF from 2014 to 2018 were identified from American College of Surgeons National Surgical Quality Improvement Program database and stratified by fracture location and by the presence or absence of DRUJ fixation. Preoperative patient characteristics and postoperative complications were compared to determine risk factors associated with DRUJ fixation. Results: We identified 1517 patients who underwent isolated radial shaft ORIF, of which 396 (26.1%) underwent DRUJ fixation. Preoperative patient characteristics and postoperative complications were similar between cohorts. Distal radioulnar joint fixation was performed in 50 (30.7%) of 163 distal radial shaft fractures, 191 (21.8%) of 875 midshaft fractures, and 3 (13.0%) of 23 proximal shaft fractures ( P = .025). Risk factors for patients readmitted include male sex (odds ratio [OR] = 12.76, P = .009) and older age (OR = 4.99, P = .035). Risk factors for patients with any postoperative complication include dependent functional status (OR = 6.78, P = .02), older age (50-69 vs <50) (OR = 2.73, P = .05), and American Society of Anesthesiologists (ASA) ≥3 (OR = 2.45, P = .047). Conclusions: The rate of DRUJ fixation in radial shaft ORIF exceeded previously reported rates of concomitant DRUJ injury, especially among distal radial shaft fractures. More distally located radial shaft fractures are significantly associated with higher rates of DRUJ fixation. Male sex is a risk factor for readmission, whereas dependent functional status, older age, and ASA ≥3 are risk factors for postoperative complications.

Background/Aim: Docetaxel (DTX) is metabolized by liver cytochromes P450 (CYP) 3A4 (CYP3A4) and 3A5 (CYP3A5) CYP3A4 activity is considered the main factor affecting the effectiveness in DTX clearance. We, therefore, explored the association between DTX-induced febrile neutropenia (FN) and concomitant polypharmacy involving CYP3A4 inhibitors in cancer patients. Patients and Methods: Among patients who received docetaxel, we compared the number of concomitant medications between patients with and without FN, and risk factors associated with FN were identified. Results: The total number of concomitant CYP3A4 inhibitors and substrates used was significantly higher in patients with FN [mean: 2.1 (95% confidence interval (CI)=1.5-2.9)] than in those without FN [mean: 1.4 (95% CI=1.0-1.8)] (p=0.01). The only risk factor for FN was the use of ≥2 concomitant CYP3A4 inhibitors and substrates in total (OR=4.82, 95% CI=1.77-14.1; p=0.002). Conclusion: Polypharmacy involving CYP3A4 inhibitors and substrates increases the risk of DTX-induced FN.
