Epidemiological and ecological studies on long bone non-unions (NU) are scarce, based on different populations and methodologies. The aim of this study was to produce a descriptive analysis of the femur, tibia, and humerus non-union epidemiology in Spain. Methods Data were obtained from the Minimum Basic Data (Conjunto Mínimo Básico de Datos, CMBD) Hospital Discharge Database of the Spanish Ministry of Health, according to the ICD9-CM coding for diagnoses and procedures, and from the National Institute of Statistics for population, generating secondary databases with the reported cases that included the code 733.82 in a disaggregated manner, by age (categorized in 5 intervals), gender, Spanish region, and calendar year (1997-2015). Percentage of non-unions related to fractures in the previous year, annual prevalence (expressed per 100,000 person-years) and period prevalence (expressed per 100,000 person-period) were calculated by age, gender, and Spanish regions. The Odds ratio (OR) was estimated with a confian in males in the femur and the humerus, while the tibia non-unions were more frequent in males and younger age.
Acute compartment syndrome (ACS) is a limb-threatening condition associated with elevated muscle compartment pressures (MCPs). The only existing treatment of ACS is to reduce MCP by fasciotomy; however, a reliable clinical method for detecting elevated MCPs is lacking. A dual-sensor (ultrasound and pressure) technology to detect elevated MCPs was previously tested on cadavers. Our goal was to examine the use of this technology in the clinical setting.
Patients with tibia fractures were prospectively enrolled. Observers used a dual-sensor probe to measure the amount of pressure required to flatten the anterior compartment fascia (CFFP). Direct-MCP measurements and 4-compartment fasciotomy were done for suspected ACS.
Fifty-two patients were enrolled into the study. Nine patients underwent fasciotomy for a clinical diagnosis of ACS. Both CFFP (p-value=8.395e-08) and delta-CFFP (p-value=4.114e-05) were significantly larger in the fasciotomy group compared to the non-fasciotomy group. CFFP measurements showed very strong correlations to the direct MCP measurements (p-value=0.006746, rho=0.9285714), and delta-CFFP showed strong correlation (p-value=0.06627, rho=0.75). CFFP measurements had good inter-observer variability, with an interclass correlation (ICC) of 0.814 (95%-Confidence Interval 0.631-0.907) and excellent intra-observer variability with an ICC of 0.942 (95%-Confidence Interval 0.921-0.958).
The results of this pilot study suggest that the proposed ultrasound-based method is useful in detecting elevated MCPs and may be helpful in the diagnosing ACS or ruling out the need for urgent fasciotomy. Large-scale clinical trials are needed to validate these claims.

A recent study has shown that NKX3.1 immunohistochemistry (IHC) is highly specific and sensitive in MCs. NKX3.1 is a nuclear marker expressed in prostatic tissue and is widely used in most laboratories to determine prostatic origin of metastatic tumours. In the current study we investigated whether this stain can be used in the diagnostic workup of MC, as it may assist in triaging cases for further molecular testing, by assessing its expression in a cohort of MCs and in a wide spectrum of sarcoma types. Furthermore, we aimed to elucidate if expression of NKX3.1 by MCs is related to androgen receptor (AR) expression. We identified NKX3.1 positive nuclear staining in 9 of 12 individual patients of MC (n=20 of 25 samples when taking into account separate episodes). Four of the five negative specimens had been previously subjected to acid-based decalcification. NKX3.1 was negative in 536 samples from 16 non-MC sarcomas derived from largely tissue microarrays (TMAs). Overall, we identified 80% sensitivity and 100% specificity for NKX3.1 IHC in MCs. The sensitivity increased to 95.2% when acid-based decalcified specimens were excluded from the analysis. No correlation between NKX3.1 expression and AR IHC was identified. In summary, our findings indicate that NKX3.1 nuclear positivity is highly sensitive and specific for MC, provided that ethylenediaminetetraacetic acid (EDTA)-based rather than acid-based decalcification is used for sample processing. NKX3.1 IHC in the right clinical and histopathological setting can potentially be sufficient for the diagnosis of MC, reserving molecular confirmation only for equivocal cases.
To determine the impact of frailty on postoperative readmission, morbidity, and mortality among patients undergoing surgery for endometrial cancer.
Patients with endometrial cancer undergoing hysterectomy between 2010 and 2014 were identified using the Nationwide Readmissions Database. Frailty was classified using criteria outlined by the Johns Hopkins Adjusted Clinical Groups Frailty Diagnoses Indicators. Primary outcomes were divided by index surgical admission (intensive level of care, mortality, non-routine discharge), 30-days (readmission and mortality), and 90-days (readmission and mortality) after discharge. Multivariable log linear regression models were fit to analyze the effect of frailty on these outcomes, adjusting for patient, hospital, and clinical factors.
From 2010 to 2014, there were 144,809 surgical endometrial cancer cases with a 1.8% frailty rate. Frailty was associated with an increased risk of intensive level of care (aRR=3.61, 95% CI 2.95, 4.42), non-routine discharge (aRR=1.59, 9ose who are readmitted. Gynecologic cancer providers should screen for frailty and consider outcomes in frail patients when counseling them for surgery.
In the United States, Black Americans are suffering from a significantly disproportionate incidence of COVID-19. Going beyond mere epidemiological tallying, the potential for racial-justice interventions, including reparations payments, to ameliorate these disparities has not been adequately explored.
We compared the COVID-19 time-varying R
curves of relatively disparate polities in terms of social equity (South Korea vs. Louisiana). Next, we considered a range of reproductive ratios to back-calculate the transmission rates β
for 4 cells of the simplified next-generation matrix (from which R
is calculated for structured models) for the outbreak in Louisiana. VER155008 manufacturer Lastly, we considered the potential structural effects monetary payments as reparations for Black American descendants of persons enslaved in the U.S. would have had on pre-intervention β
and consequently R
.
Once their respective epidemics begin to propagate, Louisiana displays R
values with an absolute difference of 1.3-2.5 compared to South Korea.
