Abstract Background Post-traumatic tibial osteomyelitis is considered as complex clinical problem due to its unique characteristics such as prolonged course, multi-staged treatment and high recurrence rate. The purpose of this study is to identify and analyze the causes and risk factors associated with infection recurrence of tibial osteomyelitis treated with Ilizarov technique. Methods From January 2011 to January 2019, a total of 149 patients with post-traumatic tibial osteomyelitis treated with Ilizarov bone transport technique were included in this study. Demographic and clinical data were collected and analyzed. Univariate analysis and logistic regression analysis were used to analyze the factors that may affect the recurrence or reinfection of post-traumatic tibial osteomyelitis after treated with Ilizarov bone transport technique. Results All included patients were successfully followed up with an average of 37.5 month (18–78 month), among them, 17 patients (11.4%) occurred with recurrence or reinfection of tibial osteomyelitis in which 2 cases were in distraction area and 15 cases in docking site. Among them, 5 patients were treated successfully with appropriate intravenous antibiotic, the remaining 12 patients were intervened by surgical debridement or bone grafting after debridement. Univariate analysis showed that Pseudomonas aeruginosa infection, bone exposure, number of previous operations (> 3 times), blood transfusion during bone transport surgery, course of osteomyelitis > 3 months, diabetes was associated with recurrence or reinfection of postoperative tibial osteomyelitis. According to the results of logistic regression analysis, Pseudomonas aeruginosa infection, bone exposure, and the number of previous operations (> 3 times) are risk factors for recurrence or reinfection of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique, with odds ratios (OR) of 6.055, 7.413, and 1.753, respectively. Conclusion The number of previous operations (> 3 times), bone exposure, and Pseudomonas aeruginosa infection are risk factors for infection recurrence of posttraumatic tibial osteomyelitis treated with Ilizarov bone transport technique.

Among them, 5 patients were treated successfully with sensitive intravenous antibiotic, the remaining 12 patients were intervened by surgical debridement or bone grafting after debridement. Univariate analysis showed that pseudomonas aeruginosa infection, bone exposure, number of previous operations (>3 times), blood transfusion during bone transport surgery, course of osteomyelitis >3 months, diabetes was associated with recurrence or reinfection of postoperative tibial osteomyelitis. According to the results of logistic regression analysis, pseudomonas aeruginosa infection, bone exposure, and the number of previous operations (>3 times) are risk factors for recurrence or reinfection of posttraumatic tibial osteomyelitis treated with Ilizarove bone transport technique, with odds ratios (OR) of 6.055, 7.413, and 1.753, respectively. Conclusion: The number of previous operations (>3 times), bone exposure, and pseudomonas aeruginosa infection are risk factors for infection recurrence of posttraumatic tibial osteomyelitis treated with Ilizarove bone transport technique.

PurposeTo summarise the prognostic associations between various clinical risk factors and the development of the acute respiratory distress syndrome (ARDS) following traumatic injury.MethodsWe conducted this review in accordance with the PRISMA and CHARMS guidelines. We searched six databases from inception through December 2020. We included English language studies describing the clinical risk factors associated with the development of post-traumatic ARDS, as defined by either the American-European Consensus Conference or the Berlin definition. We pooled adjusted odds ratios for prognostic factors using the random effects method. We assessed risk of bias using the QUIPS tool and certainty of findings using GRADE methodology.ResultsWe included 39 studies involving 5 350 927 patients. We identified the amount of crystalloid resuscitation as a potentially modifiable prognostic factor associated with the development of post-traumatic ARDS (adjusted odds ratio [aOR] 1.19 for each additional liter of crystalloid administered within first 6 h after injury, 95% CI 1.15 to 1.24, high certainty). Non-modifiable prognostic factors with a moderate or high certainty of association with post-traumatic ARDS included increasing age, non-Hispanic white race, blunt mechanism of injury, presence of head injury, pulmonary contusion, or rib fracture; and increasing chest injury severity.ConclusionWe identified one important modifiable factor, the amount of crystalloid resuscitation within the first 24 h of injury, and several non-modifiable factors associated with development of post-traumatic ARDS. This information should support the judicious use of crystalloid resuscitation in trauma patients and may inform the development of a risk-stratification tools.

Abstract Background Community-acquired extended-spectrum β-lactamase (ESBL) producing Enterobacteriaceae infections pose unique treatment challenges. Identifying risk factors associated with ESBL Enterobacteriaceae infections outside of prior colonization is important for empiric management in an era of antimicrobial stewardship. Methods We randomly selected 251 adult inpatients admitted to an Intermountain healthcare facility in Utah with an ESBL Enterobacteriaceae urinary tract infection (UTI) between January 1, 2001 and January 1, 2016. 1:1 matched controls had UTI at admission with Enterobacteriaceae but did not produce ESBL. UTI at admission was defined as urine culture positive for > 100,000 colony forming units per milliliter (cfu/mL) of Enterobacteriaceae and positive symptoms within 7 days prior or 2 days after admission. Repeated UTI was defined as more than 3 episodes of UTI within 12 months preceding index hospitalization. Cases with prior history of ESBL Enterobacteriaceae UTIs or another hospitalization three months preceding the index admission were excluded. Univariate and multiple logistic regression techniques were used to identify the risk factors associated with first episode of ESBL Enterobacteriaceae UTI at the time of hospitalization. Results In univariate analysis, history of repeated UTIs, neurogenic bladder, presence of a urinary catheter at time of admission, and prior exposure to outpatient antibiotics within past one month were found to be significantly associated with ESBL Enterobacteriaceae UTIs. When controlling for age differences, severity of illness and co-morbid conditions, history of repeated UTIs (adjusted odds ratio (AOR) 6.76, 95% confidence interval (CI) 3.60–13.41), presence of a urinary catheter at admission (AOR 2.75, 95% CI 1.25 – 6.24) and prior antibiotic exposure (AOR: 8.50, 95% CI: 3.09 – 30.13) remained significantly associated with development of new ESBL Enterobacteriaceae UTIs. Conclusion Patients in the community with urinary catheters, history of recurrent UTIs, or recent antimicrobial use can develop de novo ESBL Enterobacteriaceae UTIs.

Aims. To investigate factors associated with language delay in a cohort of 30-month-old children and determine if identification of language delay requires active contact with families.Methods. Data were collected at a pilot universal 30-month health contact. Health visitors used a simple two-item language screen. Data were obtained for 315 children; language delay was found in 33. The predictive capacity of 13 variables which could realistically be known before the 30-month contact was analysed.Results. Seven variables were significantly associated with language delay in univariate analysis, but in logistic regression only five of these variables remained significant.Conclusion. The presence of one or more risk factors had a sensitivity of 89% and specificity of 45%, but a positive predictive value of only 15%. The presence of one or more of these risk factors thus can not reliably be used to identify language delayed children, nor is it possible to define an “at risk” population because male gender was the only significant demographic factor and it had an unacceptably low specificity (52.5%). It is not possible to predict which children will have language delay at 30 months. Identification of this important ESSENCE disorder requires direct clinical contact with all families.

Abstract Background: To investigate the prevalence of and factors associated with pterygium in Han and Mongolian adults at four survey sites in Inner Mongolia, China. Methods: A population-based, cross-sectional study was conducted. Using a stratified sampling method, we eventually included 2,651 participants of at least30 years of age from a total of 3,468 eligible residents. Factors associated with pterygium were analysed using univariate analysis and logistic regression models. Results: There were 1,910 Han adults and 741 Mongolian adults included in this study. The mean± standard deviation of age for individuals in the study cohort was 48.93±11.06 years. The overall prevalence of pterygium was 6.4% (n=169), and the prevalences of bilateral and unilateral pterygium were 1.4% (n=38) and 4.8% (n=128), respectively. The most common grade of pterygium was Grade 2. After univariate analysis, eleven factors were considered in a multivariate analysis. The results indicated that age (P<0.001), education level (P<0.001), outdoor occupation (P=0.026), and time spent in rural areas (P<0.001) were significantly associated with pterygium, whereas gender and ethnicity were not risk factors. In subgroup analysis, BMI≥28 was a protective factor for Han individuals (OR 0.42, 95% CI 0.21-0.81, P=0.01), but a risk factor for Mongolian individuals (OR 2.39, 95% CI 1.02-5.58, P=0.044). The BF% in Han and Mongolian individuals had significant difference (P<0.001). Conclusions: Our results indicated that an outdoor occupation, old age and time spent in rural areas are risk factors for pterygium in Inner Mongolia. Living near an urban survey site (Hohhot and Tsining District) and having a higher education level are protective factors for pterygium. Ethnicity, gender, smoking, diabetes and high blood pressure are not associated with pterygium. Different dietary structures in Han and Mongolian adults may lead to different fat content of body and therefore contributes to the prevalence of pterygium.

Background: The purpose of this study was to identify independent risk factors associated with an increased rate of surgical site complications after elective hand surgery. Methods: This study is a retrospective review of all patients who underwent elective hand, wrist, forearm, and elbow surgery over a 10-year period at a single institution. Electronic medical records were reviewed, and information regarding patient demographics, past medical and social history, perioperative laboratory values, procedures performed, and surgical complications was collected. Surgical site complications included surgical site infections, seromas or hematomas, and delayed wound healing or wound dehiscence. A univariate analysis was then performed to identify potential risk factors, which were then included in a multivariate regression analysis. Results: A total of 3261 patients who underwent elective hand surgery and met the above inclusion and exclusion criteria were included in this study. The mean age was 57 years, with 65% female and 35% male patients. The overall surgical complication rate was 2.2%. Univariate analysis of patient factors identified male sex; number of procedures >1; history of drug, alcohol, or smoking use; American Society of Anesthesiologists (ASA) class III and IV; and serum albumin <3.5 mg/dL to be significantly associated with complications. However, multivariate regression analysis identified that only ASA class III and IV (odds ratio = 3.27) was significantly associated with surgical complications. Conclusions: Patients classified as ASA class III or IV were identified to be at a significantly increased risk of complications following elective hand surgery. Health factors which triage patients into these 2 groups may represent potentially modifiable factors to mitigate perioperative risk in the elective hand surgery population.

Abstract Background Retraction of transporting bone segment (TBS) may occur when the fixator of the TBS is removed prior to full consolidation of the distracted callus, which has adverse effect on the healing of the docking site. However, there are few reports on the retraction of TBS. The purpose of this study is to analyze the causes and risk factors of the retraction of TBS. Methods The clinical data of 37 cases with tibial bone defect treated by Ilizarov bone transport were analyzed retrospectively, in whom the TBS fixator was removed prior to full consolidation of the distracted callus and union of the docking site. Bivariate correlation was used to analyze relationship between the retraction distance of TBS and potential risk factors including age, gender, course, length of bone defect, number of operations, size of TBS, transport distance, timing and time interval of removal of TBS fixator. Risk factors with significant level were further identified using multivariate linear regression. Results Bivariate correlation showed that the timing of removal was negatively correlated with the retraction distance, and the time interval and transport distance were positively correlated with the retraction distance(p < 0.05), the age, gender, course, length of bone defect, size of TBS and number of operations were not correlated with the retraction distance(p > 0.05). Multivariate linear regression of the 3 risk factors showed that the timing of removal and time interval were the main risk factors affecting the retraction distance (p < 0.05), but the transport distance was not (p > 0.05). Conclusion The traction forces of TBS endured from the soft tissues and the unconsolidated distracted callus have elastic properties, which can make retraction of TBS. The timing of removal and time interval are the main risk factors of the retraction of TBS. In the case of early removal, another external fixation or quickly converted to internal fixation should be performed to avoid the adverse effect of more retraction.

Abstract Objectives To investigate national trends in the prevalence of anemia among children and the stability of factors associated with anemia in Nepal. Methods A series of nationally representative mid-year surveys was conducted in the same 63 wards across the mountains, hills, and Tarai of Nepal in 2013, 2014, and 2016. Each survey collected data on community, household, and individual factors to explore associations with agricultural practices and nutritional outcomes. Data were collected from consenting households that had children under 5 years, among whom a random sample was selected each year for anemia assessment using a Hb 201 + hemoglobinometer (HemoCue AB, Angelholm, Sweden), with n = 861, 794, and 837 children in each survey, respectively. Odds ratios were estimated and prevalence for 2014 and 2016 was standardized to the 2013 national surveyed population distribution. Results The national prevalence of anemia among children aged 0–59 months significantly decreased from 64.6% (95% CI: 61.3%, 67.8%) in 2013 to 51.8% (95% CI: 48.2%, 55.3%) in 2014 and then increased to 58.7% (95% CI: 55.2%, 62.0%) in 2016. Across all years, the prevalence was highest in the Tarai (57.9–70.7%) followed by the mountains (50.4–61.0%) and hills (37.6–52.0%). Within each region, the trend in prevalence followed that of the national prevalence, decreasing significantly from 2013 to 2014 and increasing in 2016. Nationally and across time, univariate analysis revealed child age <24 months, diarrhea, low dietary diversity, low dietary intake of meat, maternal hemoglobin, and lack of household access to an improved toilet to be strong and stable risk factors for anemia. Our presented paper will include findings from multivariable adjusted analysis. Conclusions The risk factors associated with anemia among children suggest the need for multi-sectoral interventions with a focus on improving diet, reducing gastrointestinal infection, and promoting hygienic and sanitary practices. Research is needed to examine why the prevalence of anemia fluctuates from year to year given that, across this period of time, many of the household and individual risk factors remain stably associated with anemia.
