External Ear Malformations (EEM) continue to be a common malformation seen in the pediatric patient population. This study aims to further elucidate the correlation between EEM and cardiac and renal anomalies.
A systematic review and meta-analysis to study the incidence of cardiac and renal anomalies associated with syndromic and isolated (EEM).
The literature search spanned multiple databases, including Google Scholar, PubMed, Scopus, Web of Science, and MEDLINE.
Studies must be focused on EEM and cardiac and/or renal anomalies. Only articles written in English were included.
General study characteristics, number of EEM patients, number of cardiac and renal anomalies and whether cases were syndromic were extracted from the studies.
Of 1,058 initial studies, 33 were included for meta-analyses. Mean JBI score for all included studies was 92.06%, indicating acceptable study quality. Interrater reliability was high, with a Cohen kappa score for all studies of 0.94. The resulting pooled prevalence of cardiac abnormalities was 20% [95% CI:13-28%], while renal abnormalities were 13% [95% CI: 7-20%]. The most common anomalies were VSD (3.725%) and renal agenesis (2.04%). The presence of syndrome data across studies was not a significant modifier of prevalence rates.
Primary limitation is due to heterogeneity in individual study methodology and reporting standards.
These results highlight a higher prevalence of cardiac-related conditions than renal anomalies in patients with both syndromic and non-syndromic EEM in the included studies, underscoring the need for thorough clinical evaluations.

Introduction
Extensive research relying on Injury Severity Scores (ISS) reports a mortality benefit from routine non-selective thoracic CTs (an integral part of pan-computed tomography (pan-CT)s). Recent research suggests this mortality benefit may be artifact. We hypothesized that the use of pan-CTs inflates ISS categorization in patients, artificially affecting admission rates and apparent mortality benefit.
Methods
Eight hundred and eleven patients were identified with an ISS >15 with significant findings in the chest area. Patient charts were reviewed and scores were adjusted to exclude only occult injuries that did not affect treatment plan. Pearson chi-square tests and multivariable logistic regression were used to compare adjusted cases vs non-adjusted cases.
Results
After adjusting for inflation, 388 (47.8%) patients remained in the same ISS category, 378 (46.6%) were reclassified into 1 lower ISS category, and 45 (5.6%) patients were reclassified into 2 lower ISS categories. Patients reclassified by 1 category had a lower rate of mortality (P < 0.001), lower median total hospital LOS (P < .001), ICU days (P < .001), and ventilator days (P = 0.008), compared to those that remained in the same ISS category.
Conclusion
Injury Severity Score inflation artificially increases survival rate, perpetuating the increased use of pan-CTs. This artifact has been propagated by outdated mortality prediction calculation methods. Thus, prospective evaluations of algorithms for more selective CT scanning are warranted.

Post-Trauma Follow-up Phone Call Shows Lower Readmission Rates for Patients Discharged From Emergency Department Compared to Inpatient Stay
2021
Background
Studies show follow-up phone calls decrease readmission rates (RR) in trauma patients and social vulnerabilities may play a role as well. Minimal literature exists comparing RR of trauma patients who required an inpatient stay to those whose treatment was limited to the Emergency Department (ED), as they are at high risk of recidivism. We hypothesized post-trauma follow-up calls would show higher RR for ED patients than those requiring inpatient stay, as well as potentially differing outcomes for minorities.
Study Design
A retrospective analysis from 2019-2020 of 1328 trauma patients from UCI Medical Center, discharged from inpatient facilities or the ED. A questionnaire script read by a nurse practitioner to patients via phone call following discharge. Data associated with readmission were captured. Multivariable logistic regression analysis was performed, controlling for patient factors including severity of injury.
Results
Patients discharged from the ED were 47.4% less likely to be readmitted than those who required an inpatient stay (P < .01). However, ED patients were 88.7% less likely to receive a prescription than inpatient stay patients (P < .01). No difference between ED and inpatient discharge contact rates was noted (P < .99). Furthermore, no difference in readmission rates was noted for minorities.
Conclusion
Post-trauma follow-up calls showed lower RR for index ED visit patients than those requiring inpatient stay, contrary to expectations. However, ED visit patients were also less likely to receive/fill prescriptions compared to those requiring inpatient stay. Ongoing analysis is warranted to further validate and improve follow-up call programs to ensure equitable health care.

First rib fractures (FRF) require substantial force and stretch, and their anatomical proximity to the vertebral and subclavian arteries make them particularly concerning. With the ever-increasing use of pan-CT scans, the incidence of diagnosed FRF has increased at least 5-fold over the past several years.3 However, mortality and other complications from rib fractures have decreased, suggesting that occult findings may not carry the same prognostic weight as clearly identifiable FRF (cFRF) (Fig. 2). Because of this uncertainty, we set out to investigate whether oFRF carry the same implications as cFRF when assessing for associated vascular and brachial plexus injuries. [...]CTA has an effective radiation dose of approximately 5.1 mSv, which translates to almost 2 years of natural background radiation.8 Epidemiological studies have found difficulty quantifying cancer risk from low-dose (<10 mSv) ionizing radiation, however this small risk can become a public health problem when applied to a large number of patients. [...]formulations of contrast media have advanced from ionic, high-osmolality to nonionic, low-osmolality which have decreased the risk of adverse reactions and contrast-induced nephropathy. [...]oFRF has a very low associated vascular injury rate and this protocol will likely not have a large impact on overall admission rates.

Introduction
It remains unclear whether an increased mortality risk in uninsured patients exists across Injury Severity Score (ISS) classifications. We hypothesized that penetrating trauma self-pay patients would have a similarly increased mortality risk across all ISS categories.
Methods
The National Trauma Data Bank (2013-2015) was queried for patients presenting with penetrating firearm, explosive, or stab wound injuries. 115 651 patients were identified and a stratified multivariable logistic regression model was used.
Results
In the >15 ISS group, self-pay patients had a lower median total hospital Length of Stay (LOS) (3 vs 8, P < .001), lower median Intensive Care Unit LOS (1 vs 3, P < .001), and lower median ventilator days (0 vs 1, P < .001). Self-pay patients had an increased risk for mortality compared to patients with private insurance in both the ≤15 ISS group (OR 2.68, P < .001) and >15 ISS group (OR 1.56, P < .001).
Conclusion
Uninsured patients have an increased mortality risk in both low and high ISS groups. A higher mortality risk among uninsured patients in the high ISS group can be explained by decreased resource availability and lower ICU days and ventilator time. However, more studies are needed to determine why there is an even greater mortality risk among uninsured patients with mild ISS.

Botryosphaeriaceae species are pathogens of apple and many other woody hosts worldwide. In this study, 34 apple orchards belonging to 22 farmers located in the south of Uruguay, the main apple production region, were surveyed. Stem canker, die-back and fruit rot were consistently observed, the most serious damage being due to cankers. From the 91 Botryosphaeriaceae isolates obtained, eight species belonging to the genera
Botryosphaeria
,
Diplodia
,
Neofusicoccum
and
Lasiodiplodia
were identified by means of phenotypic characteristics and phylogenetic analysis of the ITS region and the TEF-1α gene. The predominant species was
Botryosphaeria dothidea
(56) and the second most important was
Diplodia seriata
(16). Other species found were
Neofusicoccum parvum
(8),
D. intermedia
(5),
N. luteum
(3),
D. pseudoseriata
(1),
N. australe
(1) and
Lasiodiplodia theobromae
(1).
D. pseudoseriata
and
L. theobromae
were associated with apple for the first time. Most of the eight species were isolated from both stem and fruit and were distributed throughout the apple-producing region. Isolates of all species were able to cause typical symptoms in stems and fruits of apple when inoculated, but the most severe symptoms were caused by
L. theobromae
,
N. parvum
and

OBJECTIVE: Increased glucose 6-phosphate dehydrogenase activity has been demonstrated in heart failure. This study sought to assess myocardial glucose 6-phosphate dehydrogenase activity in retraining of the subpulmonary ventricle of adult goats. METHODS: Eighteen adult goats were divided into three groups: traditional (fixed banding), sham, and intermittent (adjustable banding, daily 12-hour systolic overload). Systolic overload (70% of systemic pressure) was maintained during a 4-week period. Right ventricle, pulmonary artery and aortic pressures were measured throughout the study. All animals were submitted to echocardiographic and hemodynamic evaluations throughout the protocol. After the study period, the animals were killed for morphological and glucose 6-phosphate dehydrogenase activity assessment. RESULTS: A 55.7% and 36.7% increase occurred in the intermittent and traditional right ventricle masses, respectively, when compared with the sham group (P<0.05), despite less exposure of intermittent group to systolic overload. No significant changes were observed in myocardial water content in the 3 groups (P=0.27). A 37.2% increase was found in right ventricle wall thickness of intermittent group, compared to sham and traditional groups (P<0.05). Right ventricle glucose 6-phosphate dehydrogenase activity was elevated in the traditional group, when compared to sham and intermittent groups (P=0.05). CONCLUSION: Both study groups have developed similar right ventricle hypertrophy, regardless less systolic overload exposure of intermittent group. Traditional systolic overload for adult subpulmonary ventricle retraining causes upregulation of myocardial glucose 6-phosphate dehydrogenase activity. It may suggest that the undesirable \"pathologic systolic overload\" is influenced by activation of penthose pathway and cytosolic Nicotinamide adenine dinucleotide phosphate availability. This altered energy substrate metabolism can elevate levels of free radicals by Nicotinamide adenine dinucleotide phosphate oxidase, an important mechanism in the pathophysiology of heart failure.
