Clinical Features of Cutaneous Paraneoplastic Syndromes in Hodgkin Lymphoma.

Cutaneous paraneoplastic syndromes due to Hodgkin lymphoma present with a wide spectrum of clinical manifestations from generalized pruritus to exfoliative erythroderma. We summarize the clinical findings and outcomes of 14 patients with Hodgkin lymphoma and associated cutaneous paraneoplastic syndromes treated at Mayo Clinic over the past 3 decades. Cutaneous paraneoplastic syndromes may be present at the time of lymphoma diagnosis, whereas in other patients, it may appear at the time of relapse, including patients with initial absence of cutaneous manifestations during the initial lymphoma presentation. Our results indicate that complete resolution of the paraneoplastic syndrome is associated with significantly improved overall survival. Recognition of cutaneous paraneoplastic syndromes is a crucial surrogate of relapsed malignancy and treatment requires targeting the underlying malignancy.

PROPOSED REVISION OF THE AMERICAN ASSOCIATION FOR SURGERY OF TRAUMA RENAL TRAUMA ORGAN INJURY SCALE: SECONDARY ANALYSIS OF THE MULTI-INSTITUTIONAL GENITOURINARY TRAUMA STUDY.

BACKGROUND: This study updates the American Association for Surgery of Trauma (AAST) Organ Injury Scale (OIS) for renal trauma using evidence-based criteria for bleeding control intervention. METHODS: This was a secondary analysis of a multi-center retrospective study including patients with high grade renal trauma from 7 Level-1 trauma centers from 2013-2018. All eligible patients were assigned new renal trauma grades based on revised criteria. The primary outcome used to measure injury severity was intervention for renal bleeding. Secondary outcomes included intervention for urinary extravasation, units of packed red blood cells (PRBCs) transfused within 24 hours, and mortality. To test the revised grading system, we performed mixed effect logistic regression adjusted for multiple baseline demographic and trauma covariates. We determined the area under the receiver-operator curve (AUC) to assess accuracy of predicting bleeding interventions from the revised grading system and compared this to 2018 AAST organ injury scale. RESULTS: based on the 2018 OIS grading system, we included 549 patients with AAST Grade III-V injuries and CT scans (III: 52% (n = 284), IV: 45% (n = 249), and V: 3% (n = 16)). Among these patients, 89% experienced blunt injury (n = 491) and 12% (n = 64) underwent intervention for bleeding. After applying the revised grading criteria, 60% (n = 329) of patients were downgraded and 4% (n = 23) were upgraded; 2.8% (n = 7) downgraded from grade V to IV, and 69.5% (n = 173) downgraded from IV to III. The revised renal trauma grading system demonstrated improved predictive ability for bleeding interventions (2018 AUC = 0.805, revised AUC = 0.883; p = 0.001) and number of units of PRBCs transfused. When we removed urinary injury from the revised system, there was no difference in its predictive ability for renal hemorrhage intervention. CONCLUSIONS: A revised renal trauma grading system better delineates the need for hemostatic interventions than the current AAST OIS renal trauma grading system. LEVEL OF EVIDENCE: II.

Short-term dynamics of linear growth among Peruvian infants in the first year of life in a population with linear growth faltering.

OBJECTIVES: Infant growth is recognized to vary over the short term, with periods of greater and lesser linear growth velocity. Our objectives were to (1) examine the potential differences in overall growth profiles between children who experienced cumulative growth faltering in the first year of life consistent with that seen by many children living in poverty in low- and middle-income countries, versus children without growth faltering and (2) test whether biological factors were associated with the timing of magnitude of growth saltations. METHODS: Thrice-weekly measurements of length were recorded for n = 61 Peruvian infants (28 boys and 33 girls) enrolled from birth to 1 year. A total of 6040 measurements were analyzed. We tested for the evidence of saltatory growth and used hurdle models to test whether the timing and magnitude of saltations varied between children with greater or lesser growth faltering. RESULTS: There were no differences in the duration of stasis periods or magnitude of growth saltations between children who were stunted at 1 year old (N = 18) versus those who were not stunted (N = 43). Children who experienced greater declines in LAZ in the first year of life trended toward longer periods between saltations than those with less of a decline (14.5 days vs. 13.4 days, p = .0512). A 1-unit increase in mid upper arm circumference for age Z-score in the 21 days prior was associated with 35% greater odds of a saltation occurring (p < .001), and a 0.128 cm greater saltation (p < .001). CONCLUSIONS: After characterizing infant growth into periods of saltation and stasis, our results suggest that increases in weight preceded increases in length.

Iron Deficiency is Related to Depressive Symptoms in United States Nonpregnant Women of Reproductive Age: A Cross-Sectional Analysis of NHANES 2005-2010.

BACKGROUND: Findings of the association between iron status and depressive symptoms in nonpregnant women of reproductive age (WRA) are equivocal, limited by a small sample size, or did not consistently control for confounders. OBJECTIVE: We tested the association between iron status and depressive symptoms in WRA with the NHANES data (2005-2010). METHODS: Nonpregnant WRA (20-44 y) with complete data on iron (ferritin and transferrin receptor (TfR)) and anemia (hemoglobin) biomarkers, depressive symptoms (Patient Health Questionnaire-9), and sociodemographic variables were included. Logistic and negative binomial regressions were used to estimate presence (odds ratios) and magnitude (prevalence ratios), respectively, for depressive symptoms by iron deficiency (ID)/anemia/ID anemia in the total sample and stratified by poverty:income ratio (≤ 1.85 or >1.85). RESULTS: Among 2516 females, the prevalence of ID was 8 to 16% (depending on the iron biomarker used), of anemia 8%, of which 52 to 65% were also ID. The prevalence of depressive symptoms was 10%. Crude logistic models showed that females with ID (TfR ≥ 8.3 mg/L or body iron <0 mg/kg) from the total sample had 1.82 (95% confidence interval [CI]: 1.24, 2.68) and 1.62 (95% CI: 1.05, 2.48), respectively, higher odds of depressive symptoms than females with iron sufficiency; these associations were attenuated after adjustments for confounders. Adjusted negative binomial models showed that females with ID (TfR ≥ 8.3 mg/L) from the total and low-income samples showed 1.19 (95% CI: 1:00, 1.40) and 1.27 (95% CI: 1.03, 1.58), respectively, higher prevalence ratios of depressive symptoms scores than females with iron sufficiency. CONCLUSIONS: These nationally representative data indicate that nonpregnant WRA with ID (based on high TfR) in the United States have higher prevalence of somatic depressive symptoms scores than those with iron sufficiency, especially if they are of low income.

Incidence and Risk Factors for Postoperative Venous Thromboembolism After Gender Affirming Vaginoplasty: A Retrospective Analysis of a Large Insurance Claims Database.

OBJECTIVES: To investigate the incidence and associated risk factors of venous thromboembolism (VTE) after gender affirming vaginoplasty. METHODS: We searched International Business Machines Corporation (IBM) Marketscan, a commercial claims database, for Current Procedural Terminology and International Classification of Diseases (ICD) procedure codes to identify patients who underwent gender affirming vaginoplasty from 2011-2020. We quantified deep venous thrombosis and pulmonary embolism using ICD-9 and ICD-10 codes found within 90 days after surgery. Univariate and multivariate analyses were performed to establish association between VTE events and age, residency location, and comorbidities. RESULTS: We identified 1588 patients who underwent gender affirming vaginoplasty. Overall, 1.1% of patients experienced a VTE within 90 days following surgery. Patients who experienced postoperative VTE were older, more likely to have had a prior VTE, less likely to be from an urban area, and more likely to have a higher Charlson Comorbidity Index score. Among patients with postoperative VTE, 47.1% had previous VTE. Among patients without a postoperative VTE, 1.3% had previous VTE. CONCLUSION: In patients undergoing gender affirming vaginoplasty, the incidence of postoperative VTE was 1.1%. Older age, rurality, increased comorbidities, and prior VTE were associated with increased risk of postoperative VTE. Current guidelines do not recommend cessation of gender affirming hormone therapy (GAHT) prior to vaginoplasty. Further research is needed to evaluate if certain high-risk patients would benefit from perioperative adjustment of GAHT or perioperative VTE prophylaxis.

Genitourinary Radiation Injury Following Prostate Cancer Treatment: Assessment of Cost and Health Care System Burden.

OBJECTIVE: To evaluate the healthcare resource impact of radiation injury following prostate cancer treatment. METHODS: Using IBM MarketScan, we performed a retrospective study of men with prostate cancer who were treated with radiotherapy and subsequently developed low-grade (LGRI) and high-grade radiation injury (HGRI). Radiation injury diagnoses included bladder neck stenosis, hematuria/cystitis, fistula, ureteral stricture, and incontinence. LGRI and HGRI included injury diagnosis without intervention and with intervention, respectively. Health care visits and costs were measured over 5 time periods including 2 years before radiation, 1 year before radiation, radiation to injury diagnosis, injury diagnosis to first intervention (LGRI), and following first intervention (HGRI). Negative binomial regression modeling was used to assess the effect of radiation injury on average cost adjusting for demographics and comorbidities. RESULTS: Between 2008 and 2017, we identified 121,027 men who received radiotherapy following prostate cancer diagnosis of which 10,057 (8.3%) experienced a HGRI. The frequency of urologic visits and average costs were similar in those without injury and LGRI. However, men with HGRI experienced higher visit frequency and monthly costs. Amongst high-grade injuries, urinary fistula had the highest frequency of visit utilization at 378 visits before first intervention and 245 visits after first intervention. Following radiation injury diagnosis, the average monthly cost was twice as high in those with HGRI ($85.78) compared to LGRI ($38.66). CONCLUSIONS: HGRI was associated with increased urologic health care use and average monthly cost when compared to those who experienced LGRI or no injury. Urinary fistula was associated with the largest resource burden.

ANKRD26 Gene Variant of Uncertain Significance in a Patient With Acute Myeloid Leukemia.

ANKRD26-related thrombocytopenia is a rare inherited disorder associated with an increased risk of malignancy. While the genetic mutations underlying this condition are well understood, there is limited knowledge regarding its contribution to myeloid neoplasms, such as acute myeloid leukemia (AML). We present a case of ANKRD26-related thrombocytopenia with a variant of uncertain significance in a patient with AML and review the pathogenesis and implications of hereditary germline mutations in disease management.

Prior COVID-19 infection associated with increased risk of newly diagnosed erectile dysfunction.

We sought to assess if COVID-19 infection recovery is associated with increased rates of newly diagnosed erectile dysfunction. Using IBM MarketScan, a commercial claims database, men with prior COVID-19 infection were identified using ICD-10 diagnosis codes. Using this cohort along with an age-matched cohort of men without prior COVID-19 infection, we assessed the incidence of newly diagnosed erectile dysfunction. Covariates were assessed using a multivariable model to determine association of prior COVID-19 infection with newly diagnosed erectile dysfunction. 42,406 men experienced a COVID-19 infection between January 2020 and January 2021 of which 601 (1.42%) developed new onset erectile dysfunction within 6.5 months follow up. On multivariable analysis while controlling for diabetes, cardiovascular disease, smoking, obesity, hypogonadism, thromboembolism, and malignancy, prior COVID-19 infection was associated with increased risk of new onset erectile dysfunction (HR 1.27; 95% CI 1.1-1.5; P = 0.002). Prior to the widespread implementation of the COVID-19 vaccine, the incidence of newly diagnosed erectile dysfunction is higher in men with prior COVID-19 infection compared to age-matched controls. Prior COVID-19 infection was associated with a 27% increased likelihood of developing new-onset erectile dysfunction when compared to those without prior infection.

A Quality Improvement Approach to Decrease the Utilization of Docusate in Hospitalized Patients.

BACKGROUND AND OBJECTIVES: Docusate sodium is a commonly prescribed medication to relieve constipation, but several studies have demonstrated its ineffectiveness. Its continued use in the hospital setting adds unnecessary cost and risk to patients. At the Mayo Clinic Florida campus, docusate was ordered for 9.7% of patients admitted to the internal medicine resident (IMED) teaching services during the month of January 2020, and the average hospital length of stay (LOS) was 3.1 days. METHODS: A multidisciplinary team of internal medicine resident physicians and pharmacists collaborated to address this quality gap through a quality improvement project. It sought to reduce the number of patients admitted to the IMED teaching services who had an order placed for docusate by 50% in less than 6 months without adversely impacting hospital LOS. Two separate interventions were devised using Six Sigma methodology and implemented to reduce the frequency of docusate orders, which involved educating internal medicine residents and hospital pharmacists, and creating an additional process-related barrier to docusate orders. RESULTS: The percentage of docusate orders decreased from 9.7% to 2.4% ( P = .004) with a grossly unchanged LOS of 3.1 days to 2.7 days ( P = .12) after 5 weeks. CONCLUSION: The implementation of a dual-pronged intervention successfully decreased the use of an ineffective medication in hospitalized patients without impacting the balancing measure, and serves as a model that can be adopted at other institutions with the hope of promoting evidence-based medical care.

A multicenter prospective cohort study of endoscopic urethral realignment versus suprapubic cystostomy after complete pelvic fracture urethral injury.

BACKGROUND: Pelvic fracture urethral injury (PFUI) occurs in up to 10% of pelvic fractures. There is mixed evidence supporting early endoscopic urethral realignment (EUR) over suprapubic tube (SPT) placement and delayed urethroplasty. Some studies show decreased urethral obstruction with EUR, while others show few differences. We hypothesized that EUR would reduce the rate of urethral obstruction after PFUI. METHODS: Twenty-six US medical centers contributed patients following either an EUR or SPT protocol from 2015 to 2020. If retrograde cystoscopic catheter placement failed, patients were included and underwent either EUR or SPT placement based on their institution's assigned treatment arm. Endoscopic urethral realignment involved simultaneous antegrade/retrograde cystoscopy to place a catheter across the urethral injury. The primary endpoint was development of urethral obstruction. Fisher's exact test was used to analyze the relationship between PFUI management and development of urethral obstruction. RESULTS: There were 106 patients with PFUI; 69 (65%) had complete urethral disruption and failure of catheter placement with retrograde cystoscopy. Of the 69 patients, there were 37 (54%) and 32 (46%) in the EUR and SPT arms, respectively. Mean age was 37.0 years (SD, 16.3 years) years, and mean follow-up was 463 days (SD, 280 days) from injury. In the EUR arm, 36 patients (97%) developed urethral obstruction compared with 30 patients (94%) in the SPT arm ( p = 0.471). Urethroplasty was performed in 31 (87%) and 29 patients (91%) in the EUR and SPT arms, respectively ( p = 0.784). CONCLUSION: In this prospective multi-institutional study of PFUI, EUR was not associated with a lower rate of urethral obstruction or need for urethroplasty when compared with SPT placement. Given the potential risk of EUR worsening injuries, clinicians should consider SPT placement as initial treatment for PFUI when simple retrograde cystoscopy is not successful in placement of a urethral catheter. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Modelling population responses to workplace minimum dietary standards introduced as workers return after social lockdowns.

BACKGROUND: Diet norms are the shared social behaviours and beliefs about diets. In many societies, including the UK, these norms are typically linked to unhealthy diets and impede efforts to improve food choices. Social interactions that could influence one another's food choices, were highly disrupted during the lockdowns in response to the COVID-19 pandemic. A return to workplaces and re-establishment of eating networks may present an opportunity to influence dietary norms by introducing minimum dietary standards to in workplaces, which could then spread through wider home and workplace networks. METHODS: An agent-based model was constructed to simulate a society reflecting the structure of a city population (1000 households) to explore changes in personal and social diet-related norms. The model tracked individual meal choices as agents interact in home, work or school settings and recorded changes in diet quality (range 1 to 100). Scenarios were run to compare individuals' diet quality with the introduction of minimum dietary standards with degrees of working from home. RESULTS: The more people mixed at work the greater the impact of minimum standards on improving diet norms. Socially isolated households remained unaffected by minimum standards, whereas household members exposed directly, in workplaces or schools, or indirectly, influenced by others in the household, had a large and linear increase in diet quality in relation to minimum standards (0.48 [95% CI 0.34, 0.62] per unit increase in minimum standards). Since individuals regressed to the new population mean, a small proportion of diets decreased toward lower population norms. The degree of return to work influenced the rate and magnitude of change cross the population (-2.4 points [-2.40, -2.34] in mean diet quality per 20% of workers isolating). CONCLUSIONS: These model results illustrate the qualitative impact social connectivity could have on changing diets through interventions. Norms can be changed more in a more connected population, and social interactions spread norms between contexts and amplified the influence of, for example, workplace minimum standards beyond those directly exposed. However, implementation of minimum standards in a single type of setting would not reach the whole population and in some cases may decrease diet quality. Any non-zero standard could yield improvements beyond the immediate adult workforce and this could spill between social contexts, but would be contingent on population connectivity.

Trends in Risk Factors and Symptoms Associated With SARS-CoV-2 and Rhinovirus Test Positivity in King County, Washington, June 2020 to July 2022.

Importance: Few US studies have reexamined risk factors for SARS-CoV-2 positivity in the context of widespread vaccination and new variants or considered risk factors for cocirculating endemic viruses, such as rhinovirus. Objectives: To evaluate how risk factors and symptoms associated with SARS-CoV-2 test positivity changed over the course of the pandemic and to compare these with the risk factors associated with rhinovirus test positivity. Design, Setting, and Participants: This case-control study used a test-negative design with multivariable logistic regression to assess associations between SARS-CoV-2 and rhinovirus test positivity and self-reported demographic and symptom variables over a 25-month period. The study was conducted among symptomatic individuals of all ages enrolled in a cross-sectional community surveillance study in King County, Washington, from June 2020 to July 2022. Exposures: Self-reported data for 15 demographic and health behavior variables and 16 symptoms. Main Outcomes and Measures: Reverse transcription-polymerase chain reaction-confirmed SARS-CoV-2 or rhinovirus infection. Results: Analyses included data from 23 498 individuals. The median (IQR) age of participants was 34.33 (22.42-45.08) years, 13 878 (59.06%) were female, 4018 (17.10%) identified as Asian, 654 (2.78%) identified as Black, and 2193 (9.33%) identified as Hispanic. Close contact with an individual with SARS-CoV-2 (adjusted odds ratio [aOR], 3.89; 95% CI, 3.34-4.57) and loss of smell or taste (aOR, 3.49; 95% CI, 2.77-4.41) were the variables most associated with SARS-CoV-2 test positivity, but both attenuated during the Omicron period. Contact with a vaccinated individual with SARS-CoV-2 (aOR, 2.03; 95% CI, 1.56-2.79) was associated with lower odds of testing positive than contact with an unvaccinated individual with SARS-CoV-2 (aOR, 4.04; 95% CI, 2.39-7.23). Sore throat was associated with Omicron infection (aOR, 2.27; 95% CI, 1.68-3.20) but not Delta infection. Vaccine effectiveness for participants fully vaccinated with a booster dose was 93% (95% CI, 73%-100%) for Delta, but not significant for Omicron. Variables associated with rhinovirus test positivity included being younger than 12 years (aOR, 3.92; 95% CI, 3.42-4.51) and experiencing a runny or stuffy nose (aOR, 4.58; 95% CI, 4.07-5.21). Black race, residing in south King County, and households with 5 or more people were significantly associated with both SARS-CoV-2 and rhinovirus test positivity. Conclusions and Relevance: In this case-control study of 23 498 symptomatic individuals, estimated risk factors and symptoms associated with SARS-CoV-2 infection changed over time. There was a shift in reported symptoms between the Delta and Omicron variants as well as reductions in the protection provided by vaccines. Racial and sociodemographic disparities persisted in the third year of SARS-CoV-2 circulation and were also present in rhinovirus infection. Trends in testing behavior and availability may influence these results.

Gordonia bronchialis Bacteremia in a Patient With Burkitt Lymphoma: A Case Report and Literature Review.

Gordonia species are gram-positive, partially acid-fast bacteria recognized as pathogens associated with medical devices and catheter-related infections in immunocompetent and immunocompromised hosts. We describe a rare case of Gordonia bronchialis bacteremia due to central venous catheter infection in a patient undergoing active chemotherapy for Burkitt lymphoma. We review the diagnosis, treatment, and extent of infections reported throughout medical literature about this rare and emerging pathogen.

The Outcomes of Pelvic Fracture Urethral Injuries Stratified by Urethral Injury Severity: A Prospective Multi-institutional Genitourinary Trauma Study (MiGUTS).

OBJECTIVE: To determine patient outcomes across a range of pelvic fracture urethral injury (PFUI) severity. PFUI is a devastating consequence of a pelvic fracture. No study has stratified PFUI outcomes based on severity of the urethral distraction injury. METHODS: Adult male patients with blunt-trauma-related PFUI were followed prospectively for a minimum of six months at 27 US medical centers from 2015-2020. Patients underwent retrograde cystourethroscopy and retrograde urethrography to determine injury severity and were categorized into three groups: (1) major urethral distraction, (2) minor urethral distraction, and (3) partial urethral injury. Major distraction vs minor distraction was determined by the ability to pass a cystoscope retrograde into the bladder. Simple statistics summarized differences between groups. Multi-variable analyses determined odds ratios for obstruction and urethroplasty controlling for urethral injury type, age, and Injury Severity Score. RESULTS: There were 99 patients included, 72(72%) patients had major, 13(13%) had minor, and 14(14%) had partial urethral injuries. The rate of urethral obstruction differed in patients with major (95.8%), minor (84.6%), and partial injuries (50%) (P < 0.001). Urethroplasty was performed in 90% of major, 66.7% of minor, and 35.7% of partial injuries (P < 0.001). CONCLUSION: In PFUI, a spectrum of severity exists that influences outcomes. While major and minor distraction injuries are associated with a higher risk of developing urethral obstruction and need for urethroplasty, up to 50% of partial PFUI will result in obstruction, and as such need to be closely followed.

Risk of Postoperative Thromboembolism in Men Undergoing Urological Prosthetic Surgery: An Assessment of 21,413 Men.

PURPOSE: We assessed venous thromboembolism (VTE) and associated risk factors following artificial urinary sphincter (AUS) and inflatable penile prosthesis (IPP) surgery. MATERIALS AND METHODS: Using IBM® MarketScan, a commercial claims database, patients undergoing AUS and IPP surgery were identified using CPT® and ICD (International Classification of Diseases)-10 procedure codes between 2008 and 2017. ICD-9 and -10 codes were used to identify health care visits associated with lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days of surgery. Covariates were assessed using a multivariable model to determine association with outcome of DVT and/or PE. RESULTS: A total of 21,413 men underwent AUS (4,870) or IPP (16,543) surgery between 2008 and 2017 with a median age of 62 years and 68 years, respectively. DVT and PE events following AUS and IPP surgery occurred in 1.54% and 1.04%, respectively. A history of varicose veins (HR 2.76; 95% CI 1.11-6.79), prior history of DVT (HR 13.65; 95% CI 7.4-25.19), or PE (HR 7.65; 95% CI 4.01-14.6) in those undergoing AUS surgery was highly associated with development of postoperative VTE. Likewise, prior history of DVT (HR 12.6; 95% CI 7.99-19.93) and PE (HR 8.9; 95% CI 5.6-14.13) was strongly associated with a VTE event following IPP surgery. CONCLUSIONS: In a large cohort of men undergoing AUS and IPP surgery, 1.54% and 1.04% of men experienced a VTE event within 90 days of surgery, respectively. Prior history of varicose veins, DVT, and PE was associated with an increased likelihood of developing a postoperative DVT or PE.

Determinants of vaccine coverage and timeliness in a northern Pakistani village.

The incidence of vaccine preventable disease in Pakistan remains high despite a long-standing Expanded Program on Immunization (EPI). We describe vaccine completeness, timeliness and determinants of coverage from a remote rural cohort (2012-2014). Vaccination histories were taken from EPI records. Vaccination was complete if all doses were received according to the EPI schedule and timely if doses were not ≥3 days early or ≥ 28 days late. Three models are presented: a multivariable logistic regression of household demographic and socioeconomic factors associated with complete vaccination, a multivariable mixed effects logistic regression assessing whether or not the vaccine was administered late (versus on-time), and a mixed effects multivariable Poisson regression model analysing the interval (in days) between vaccine doses. Of 959 enrolled children with full vaccination histories, 88.2 and 65.1% were fully vaccinated following either the pentavalent or DPT/HBV schedules if measles was excluded; coverage dropped to 50.0 and 27.1% when both doses of measles were included. Sixty-four (6.7%) were unvaccinated. Coverage and timeliness declined with subsequent doses. Migrating into the village after 1995 (95%CI 1.88 to 5.17) was associated with late vaccination. Being male, having an older father, and having parents with at least some formal education reduced the likelihood of a late dose. The interval between doses was consistent at 5 weeks (compared with the 4 weeks recommended by EPI). None of the socio-demographic variables were related to the likelihood of receiving full coverage. Vaccine coverage in Oshikhandass was higher than national averages. Measles vaccine coverage and timeliness were low; special consideration should be paid to this vaccine. The local vaccination schedule differed from the EPI, but the consistency suggests good local administration.

Nephrectomy Is Not Associated with Increased Risk of Mortality or Acute Kidney Injury after High-Grade Renal Trauma: A Propensity Score Analysis of the Trauma Quality Improvement Program (TQIP).

PURPOSE: Patients with high-grade renal trauma (HGRT) undergoing nephrectomy may be at higher risk for mortality compared to those treated conservatively. However, no study has controlled for degree of hemorrhage as a measure of shock. We hypothesized that after controlling for blood transfusions and other factors, nephrectomy after HGRT would be associated with increased mortality and acute kidney injury (AKI). MATERIALS AND METHODS: We identified adult patients with HGRT (American Association for the Surgery of Trauma grade III-V) in TQIP (2013-2017). Propensity scoring was used to adjust for the probability of nephrectomy. Conditional logistic regression was used to analyze the association between nephrectomy and mortality and AKI. We adjusted for patient characteristics, injury specifics, and physiological factors including blood transfusions. RESULTS: There were 12,780 patients with HGRT, and 1,014 (7.9%) underwent nephrectomy. Mortality was 10.6% and 4.2% in the nephrectomy and nonnephrectomy groups, respectively (p <0.001). In nephrectomy patients, 8.6% experienced AKI vs 2.4% of nonnephrectomy patients (p <0.001). In the adjusted analysis, there was no association between nephrectomy and mortality (OR=0.367, 95% CI 0.09-1.497, p=0.162). There was also no association between nephrectomy and AKI. Increasing age, nonCaucasian race, increasing Injury Severity Score, decreasing Glasgow Coma Score and blood transfusions were associated with higher mortality. For AKI, independent predictors included increasing age, male sex, and blood transfusions. CONCLUSIONS: After adjusting for volume of blood transfused in the first 24 hours, nephrectomy after HGRT was not associated with increased mortality or AKI. As a clinical principle, trauma nephrectomy should be avoided when possible.
