Urologia. 2021 May 22:3915603211018441. doi: 10.1177/03915603211018441. Online ahead of print.

ABSTRACT

OBJECTIVES: To evaluate the role of the microbiological profile and of disease-related factors in the management of patients affected with Fournier’s gangrene (FG).

PATIENTS AND METHODS: Data regarding patients admitted for FG at nine Italian Hospitals (March 2007-June 2018) were collected. Patients were stratified according to the number of microorganisms documented: Group A – one microorganism; Group B – two microorganisms; Group C – more than three microorganisms. Baseline blood tests, dedicated scoring systems, predisposing risk factors, disease’s features, management and post-operative course were analyzed. UpSet technique for visualizing set intersections in a matrix layout and Cuzick’s nonparametric test for trend across ordered groups were used.

RESULTS: Eighty-one patients were available for the analysis: 18 included in Group A, 32 in Group B, 31 in Group C. The most common microorganism isolated was Escherichia coli. In Group B-C, Escherichia coli was often associated to Enterococcus faecalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Statistically significant positive association was highlighted among the number of pathogens (Group A vs B vs C) and serum C-reactive Protein (p < 0.001), procalcitonin (p = 0.02) and creatinine (p = 0.03). Scoring systems were associated with the number of microorganisms detected (p < 0.02). A significant association between the number of microorganisms and the use of VAC therapy and need of a fecal diversion was found (p < 0.02). The number of microorganisms was positively associated with the length of stay (LOS) (p = 0.02). Ten weeks after initial debridement, wound closure was achieved in 11 (91.7%), 22 (84.6%) and 20 (80%) patients in Group A, B, and C, respectively, with no differences in overall survival.

CONCLUSION: Polymicrobial infections in FG are positively associated with inflammatory scores, the need for fecal diversion and the LOS. This results may help the counseling and the clinical management of this rare niche of patients.

Third trimester ultrasound estimated fetal weight for increasing prenatal prediction of small-for-gestational age newborns in low-risk pregnant women

J Matern Fetal Neonatal Med. 2021 May 23:1-6. doi: 10.1080/14767058.2021.1920915. Online ahead of print.

ABSTRACT

AIM: The early detection of small-for-gestational age (SGA) fetuses and newborns is pivotal in the prevention of perinatal mortality.

OBJECTIVES: To compare the predictive capability of performing ultrasound-based estimated fetal weight (EFW) at 32 versus 36 weeks’ gestation on the detection rate of SGA fetuses and SGA newborns at delivery, and to find a better cutoff level to consider a fetus at risk of being born small.

MATERIAL AND METHODS: Nine hundred fifteen low-risk pregnant women were assessed at both 32 and 36 weeks’ gestation. EFW centile was calculated in both occasions. The rate of SGA fetuses was compared. SGA fetuses were considered when both abdominal circumference (AC) and EFW were below the 10th centile from a total of 488 delivered at our Hospital. Paired comparisons between ultrasound at 32 and 36 weeks’ gestation were done to predict SGA at delivery. Percentages of SGA fetuses were compared by chi-squared test. ANOVA test was used for comparing centiles among groups. Receiver operating characteristic (ROC) curve was used to find the best cutoff ultrasound centile to predict SGA at delivery. Statistical significance was previously set at 95% level (p < .05).

RESULTS: Ultrasound-based EFW at 32 weeks showed 23 cases of SGA (2.5%) while at 36 weeks this rate increased up to 4% (37/915) (p < .000001). When comparing both outcomes, 2.8% of those catalogued as adequate-for-gestational age (AGA) at 32 weeks were cases of SGA at 36 weeks. In addition, 47.8% of those diagnosed as SGA were not confirmed at 36 weeks. Only 12.3% of SGA neonates were identified at 32 weeks’ gestation ultrasound, while using the 36 weeks’ gestation approach this rate increased up to 30.9%. So, only a low proportion of SGA neonates were SGA fetuses at any of these two gestational ages. However, the area under the curve (AUC) at 36 weeks was as high as 0.86. Being a matter of cutoff rather than a matter of choosing the correct variable, ROC analysis showed that the best cutoff for prediction having the best sensitivity (0.80) with the best specificity (0.77) was 28th centile of EFW. This represents 24.9% of the studied women (228/915).

CONCLUSIONS: In general, ultrasound at 36 weeks has better performance detecting SGA fetuses than ultrasound at 32 weeks and we suggest to definitively change from 32 to 36 weeks in order to increase the detection rate of SGA fetuses. Moreover, in order to detect those fetuses who will grow below the lower level of the normal range in the last month of pregnancy, we suggest that those with EFW below the 28th centile at 36 weeks should be rescanned later in pregnancy to identify prenatally as many cases as we can of SGA newborns.

Body Mass Index, Multi-Morbidity, and COVID-19 Risk Factors as Predictors of Severe COVID-19 Outcomes

J Prim Care Community Health. 2021 Jan-Dec;12:21501327211018559. doi: 10.1177/21501327211018559.

ABSTRACT

PURPOSE: The purpose of the present study was to investigate body mass index, multi-morbidity, and COVID-19 Risk Score as predictors of severe COVID-19 outcomes.

PATIENTS: Patients from this study are from a well-characterized patient cohort collected at Mayo Clinic between January 1, 2020 and May 23, 2020; with confirmed COVID-19 diagnosis defined as a positive result on reverse-transcriptase-polymerase-chain-reaction (RT-PCR) assays from nasopharyngeal swab specimens.

MEASURES: Demographic and clinical data were extracted from the electronic medical record. The data included: date of birth, gender, ethnicity, race, marital status, medications (active COVID-19 agents), weight and height (from which the Body Mass Index (BMI) was calculated, history of smoking, and comorbid conditions to calculate the Charlson Comorbidity Index (CCI) and the U.S Department of Health and Human Services (DHHS) multi-morbidity score. An additional COVID-19 Risk Score was also included. Outcomes included hospital admission, ICU admission, and death.

RESULTS: Cox proportional hazards models were used to determine the impact on mortality or hospital admission. Age, sex, and race (white/Latino, white/non-Latino, other, did not disclose) were adjusted for in the model. Patients with higher COVID-19 Risk Scores had a significantly higher likelihood of being at least admitted to the hospital (HR = 1.80; 95% CI = 1.30, 2.50; P < .001), or experiencing death or inpatient admission (includes ICU admissions) (HR = 1.20; 95% CI = 1.02, 1.42; P = .028). Age was the only statistically significant demographic predictor, but obesity was not a significant predictor of any of the outcomes.

CONCLUSION: Age and COVID-19 Risk Scores were significant predictors of severe COVID-19 outcomes. Further work should examine the properties of the COVID-19 Risk Factors Scale.

Open vs Minimally Invasive Scarf Osteotomy for Hallux Valgus Correction: A Randomized Controlled Trial[Formula: see text]

Foot Ankle Int. 2021 May 22:10711007211003565. doi: 10.1177/10711007211003565. Online ahead of print.

ABSTRACT

BACKGROUND: Minimally invasive (MI) surgery is becoming increasingly popular in the treatment of hallux valgus (HV). The scarf osteotomy is an effective procedure with a track record in open HV surgery. We adapted this effective osteotomy to MI surgery as a novel technique never reported before. The aim of this study was to compare the clinical and radiologic outcomes of patients who underwent open or MI scarf.

METHODS: Between 2017 and 2018, 58 patients were randomized to either open or MI scarf to treat HV deformity. Prospective patient-reported outcome measures and weightbearing radiographs were obtained. Data included the AOFAS score, radiologic angular correction, operative time, fluoroscopy radiation dose, and postoperative pain on visual analog scale (VAS).

RESULTS: The mean follow-up was of 21 (range, 12-38) months. Radiologic measurements (postoperative hallux valgus angle, first-to-second intermetatarsal angle, and distal metaphyseal articular angle) were similar in both groups and showed statistically significant improvement from preoperative measures. The mean operative time for the MI group was 16.7 vs 26.1 minutes in the open group, a statistically significant difference. Radiation exposure was 14 times higher in the MI group when compared to the open group (mean: 34 vs 2.4 mGy/cm2, P < .001). There were no major complications in either group.

CONCLUSIONS: The MI scarf provides a clinically and radiologically equivalent outcome to open scarf for the treatment of HV with reduced operative time and immediate postoperative VAS for pain but is associated with a small increase in radiation exposure.

LEVEL OF EVIDENCE: Level I, randomized controlled trial.

Development of a finite element neck model for head-first compressive impacts: Toward the assessment of motorcycle neck protective equipment

Proc Inst Mech Eng H. 2021 May 22:9544119211018112. doi: 10.1177/09544119211018112. Online ahead of print.

ABSTRACT

Head-first compressive impacts occur in motorcycle crashes and may result in serious to fatal neck injuries to riders. Equipment to protect the riders’ necks from these injuries are available in the market; however, their effectiveness in reducing injury risk is not clear, either due to the lack of scientific evidences or assessment with any prevalently accepted standard. This paper presents a finite element ligamentous neck model, developed as a computationally efficient tool, for future use in the computational phase of assessment process of neck protective equipment. The 3D cervical spine was generated using the mean statistical dimensions of vertebrae and proposed constitutive models, provided in the scientific literature. Ligaments, for the vertebra-vertebra and Hybrid III head-vertebra ligamentous joints, were introduced with the aid of published anatomical descriptions. For validation, the response of the head-neck system under compressive loadings and the flexion-extension bending stiffness of the neck at the segment level were compared against experimental data. The advanced CORrelation and Analysis (CORA) algorithm was applied on the validation responses to assess biofidelity of the model. The results indicate that the model is functional and meets ISO/TR9790 standard as a “good” biofidelic model.

Understanding and Promoting Racial Diversity in Healthcare Settings to Address Disparities in Pandemic Crisis Management

J Prim Care Community Health. 2021 Jan-Dec;12:21501327211018354. doi: 10.1177/21501327211018354.

ABSTRACT

BACKGROUND: Health disparities have become apparent since the beginning of the COVID-19 pandemic. When observing racial discrimination in healthcare, self-reported incidences, and perceptions among minority groups in the United States suggest that, the most socioeconomically underrepresented groups will suffer disproportionately in COVID-19 due to synergistic mechanisms. This study reports racially-stratified data regarding the experiences and impacts of different groups availing the healthcare system to identify disparities in outcomes of minority and majority groups in the United States.

METHODS: Studies were identified utilizing PubMed, Embase, CINAHL Plus, and PsycINFO search engines without date and language restrictions. The following keywords were used: Healthcare, raci*, ethnic*, discriminant, hosti*, harass*, insur*, education, income, psychiat*, COVID-19, incidence, mortality, mechanical ventilation. Statistical analysis was conducted in Review Manager (RevMan V.5.4). Unadjusted Odds Ratios, P-values, and 95% confidence intervals were presented.

RESULTS: Discrimination in the United States is evident among racial groups regarding medical care portraying mental risk behaviors as having serious outcomes in the health of minority groups. The perceived health inequity had a low association to the majority group as compared to the minority group (OR = 0.41; 95% CI = 0.22 to 0.78; P = .007), and the association of mental health problems to the Caucasian-American majority group was low (OR = 0.51; 95% CI = 0.45 to 0.58; P < .001).

CONCLUSION: As the pandemic continues into its next stage, efforts should be taken to address the gaps in clinical training and education, and medical practice to avoid the recurring patterns of racial health disparities that become especially prominent in community health emergencies. A standardized tool to assess racial discrimination and inequity will potentially improve pandemic healthcare delivery.

Evaluation of the Safety and Efficacy of a Novel Thrombin Containing Combination Hemostatic Powder Using a Historical Control

Clin Appl Thromb Hemost. 2021 Jan-Dec;27:10760296211017238. doi: 10.1177/10760296211017238.

ABSTRACT

This clinical study compares 2 hemostatic agents, a novel combination powder (CP) (HEMOBLAST Bellows) and an established polysaccharide starch powder (PP) (Arista AH) to assess the usefulness of CP. Retrospective comparative analysis of CP (July 2018 to July 2019, 68 patients) to PP (January 2011 to January 2013, 94 patients) in cardiothoracic patients was performed using linear regression models adjusting for age, sex, and procedure type for the endpoints: blood loss; protamine to skin closure time (hemostasis time); chest tube output and blood products required 48 hours postoperatively; ICU stay; postoperative comorbidities; and 30 day mortality. 162 patients (108 M: 54 F) underwent 162 cardiothoracic surgical procedures including: transplantation (n = 44), placement of ventricular assist device (n = 87), and others (n = 31). Use of CP compared to PP (Estimated Mean Difference [95% CI], P-value) produced significant reductions: blood loss (mL) (-886.51 [-1457.76, -312.26], P = 0.003); protamine to skin closure time (min) (-16.81 [-28.03, -5.59], P = 0.004); chest tube output (48 hrs, mL) (-445.76 [-669.38, -222.14], P < 0.001); packed red blood cell transfusions (units) (-0.98 [-1.56, -0.4], P = 0.001); and postoperative comorbidities (-0.31 [-0.55, -0.07], P = 0.012). There were no differences in the ICU stay (4.07 [-2.01, 10.15], P = 0.188) or 30-day mortality (0.57 [0.20, 1.63], P = 0.291). The use of CP in complex cardiothoracic operations resulted in improved hemostasis and significant clinical benefits in blood loss, transfusion requirements, morbidity, and time in operating room.

In-vitro assessment of release of silicone oil droplets with the use of variety of syringes and needles used in intravitreal injections

Eur J Ophthalmol. 2021 May 22:11206721211019580. doi: 10.1177/11206721211019580. Online ahead of print.

ABSTRACT

PURPOSE: To assess the variability of silicone oil (SO) particles released across syringes from the same lot and the role of different needle gauges.

MATERIALS AND METHODS: Four syringe models and six needle models were assessed for SO release. About 50 microliters of a buffer solution were loaded into the syringe, needle or syringe/needle setup. The data were analyzed by imaging flow cytometry with fluorescently labeling for SO.

RESULTS: All syringe models had a high coefficient of variation in SO release across syringes from the same lot. The amount of SO was significantly greater in the syringe when the needle was attached. SO particles with the BD 30G needle attached to the syringe were statistically greater than the 27G counterpart (p = 0.005). None of the other comparisons was statistically different. Finally, the number of SO particles was higher in the syringe/needle setup than in needles only (p = 0.0024).

CONCLUSION: We found a high variability in SO content across syringes from the same lot. Additionally, there was no clear association between needle gauge and the number of SO particles, as well as their coefficient of variation. Finally, the needles accounted for a small number of SO particles in comparison to the combined syringe-needle setup.

Sex-Specific Differences Following Lateral Ankle Ligament Repair

Foot Ankle Int. 2021 May 22:10711007211004191. doi: 10.1177/10711007211004191. Online ahead of print.

ABSTRACT

BACKGROUND: Chronic ankle instability is a common condition that can be treated with lateral ankle ligament repair. These procedures have a reported success rate greater than 85% in the literature, but little has been reported about the differences in postoperative outcomes between males and females. The purpose of this study was to evaluate sex-specific outcomes following lateral ankle ligament repair.

METHODS: In this systematic review and meta-analysis, we used Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to search for articles on electronic databases and included studies in which study participants underwent primary lateral ligament repair and sex-specific outcomes were evaluated. Functional postoperative outcomes for males and females were recorded and statistically analyzed.

RESULTS: Out of 2768 studies, 7 (0.25%) met inclusion criteria and were analyzed in this review. These studies included 618 patients (402 males [65%] and 216 females [35%]) who underwent primary lateral ligament repair for ankle instability. Karlsson score (P = .1582) and American Orthopaedic Foot & Ankle Society (AOFAS) score (P = .1586) analyses found no statistically significant difference between males and females. Postoperative success rate-defined as a “good” or “excellent” Karlsson score (>81)-was not found to be significantly different between males and females (P = .9374).

CONCLUSION: There was no difference in postoperative mean Karlsson scores, AOFAS scores, or success rates between males and females who underwent primary lateral ankle ligament repair.

LEVEL OF EVIDENCE: Level IV, therapeutic.

Conventional vs Accelerated Rehabilitation Protocol Following Reattachment of Achilles Tendon for Insertional Achilles Tendinopathy

Foot Ankle Int. 2021 May 24:10711007211003871. doi: 10.1177/10711007211003871. Online ahead of print.

ABSTRACT

BACKGROUND: No studies have compared early vs conventional postoperative weightbearing following suture bridge Achilles tendon reattachment. We, therefore, evaluated postoperative functional outcomes in these patients.

METHODS: We collected data on 49 patients who underwent surgical treatment of insertional Achilles tendinopathy using a central Achilles tendon-splitting approach and reattachment with suture bridge technique by a single surgeon. Functional outcomes were measured by a visual analog scale (VAS) for pain, Foot and Ankle Ability Measure (FAAM), and Short Form Health Survey (SF-36) at 3, 6, and 12 months postoperatively. The differences in outcomes were analyzed using multiple linear regression.

RESULTS: Eighteen and 31 patients underwent the conventional and accelerated protocols, respectively; their corresponding mean ages were similar, 53 and 57 years, as were all other baseline characteristics. The mean scores (conventional vs accelerated group) for VAS for pain, FAAM, and SF-36 in the conventional group at 3 months postoperatively were 4 ± 1 vs 3 ± 1 points, 53 ± 8 vs 68 ± 3 points, and 57 ± 15 vs 67 ± 10 points (P < .05 for each comparison). There were no statistically significant differences between the groups at 6 and 12 months postoperatively. All patients could perform the single heel raise test at 6 months, and none experienced complications.

CONCLUSION: In this small study, short-term functional outcomes were better in the accelerated group. More data are needed before the accelerated program can be recommended.

LEVEL OF EVIDENCE: Level II, prospective comparative study.
