Effectiveness of the polyglycolic acid patch in preventing prolonged air leakage after pulmonary decortication

ANZ J Surg. 2022 Jun 28. doi: 10.1111/ans.17874. Online ahead of print.

ABSTRACT

AIM: This study aimed to investigate the effectiveness of an absorbable polyglycolic acid patch (PGA) in the early prevention of alveolar air leaks after pulmonary decortication operations.

METHODS: Between January 2016 and December 2019, files of 185 patients with pleural effusion, empyema, or hemothorax were examined retrospectively. Thirty-five patients who underwent decortication surgery were included in the study. Two-way posteroanterior (PA) chest x-ray, computed tomography (CT), pulmonary function tests (PFT), arterial blood gas, hemogram, and biochemical tests were performed for all patients before the operation. The patients were divided into two groups. Group 1 was composed of 16 patients (45.7%) with standard decortication, and Group 2 was formed with 19 patients (54.3%) with standard decortication + PGA patch.

RESULTS: The median age was 55 years (minimum = 25, maximum = 75) and the vast majority (82.9%; n = 29) of patients were males. There was no significant difference between groups in age, aetiology, or sex. The most common etiological cause in both Group 1 and Group 2 was nonspecific infection (56.3% and 73.7%, respectively). When Group 2 and Group 1 were compared regarding median times (day) of air leak cessation (Group 2 = 4; Group 1 = 8.5), chest drain removal (Group 2 = 5; Group 1 = 10), and hospital discharge times (Group 2 = 8; Group 1 = 13),the durations were statistically significantly shorter in Group 2 than in Group 1 (P < 0.001).

CONCLUSION: Use of the PGA patch in pulmonary decortication operations significantly reduced the duration of air leaks, drain removal, and discharge time from the hospital in the postoperative period.

Acetabular paralabral cysts demonstrating perineural propagation

Br J Radiol. 2022 Jun 28:20211306. doi: 10.1259/bjr.20211306. Online ahead of print.

ABSTRACT

OBJECTIVE: Acetabular paralabral cysts are common and are almost always associated with labral tears. Uncommonly, they extend into the periacetabular soft tissues or may propagate along peripheral nerves causing pain and hip dysfunction. The aim was to evaluate the clinical and MRI presentations of such cases including perineural propagation.

METHODS: Retrospective cross-sectional study with a search of electronic health records for cases of acetabular paralabral cysts demonstrating perineural propagation was performed. Clinical and MR imaging features were tabulated after re-review by experienced musculoskeletal radiologists, and available outcomes were recorded. Descriptive statistics were performed.

RESULTS: 14 cases were recorded. The mean age was 56.9 years (range = 30-79 years) and female:male ratio was 1:2.6. The commonest presenting complaint was hip pain (10/14, 71.4%). Other complaints included groin pain, perineal pain and hip dysfunction. No symptoms were attributed to the acetabular paralabral cyst in 3/14 patients (21.4%). None had foot drop. The cysts were multilocular in all cases and were homogenously T2 hyperintense in 13/14 (92.9%). Labral tears were identified in 11/14 cases (78.6%). The sciatic nerve was most commonly involved in 5/14 cases (35.7%) with the obturator, medial femoral cutaneous nerve, femoral nerve, superior and inferior gluteal nerves also affected.No intervention was undertaken in 9/14 cases (64.3%). 5/14 (35.7%) underwent image guided aspiration and corticosteroid injection. 4/5 such patients reported reduced pain following the procedure.

CONCLUSIONS: Paralabral cysts demonstrating perineural propagation are uncommon and exhibit varied presentations. Most patients who underwent image guided or surgical interventions reported an improvement in symptoms.

ADVANCES IN KNOWLEDGE.: This is the first description of a series of patients with acetabular paralabral cysts demonstrating perineural propagation in the literature. A comprehensive description of their clinical and imaging characteristics and interventions/outcomes where relevant is provided.

Prostatic artery occlusion versus prostatic artery embolization for the management of benign prostatic Hyperplasia: Early results in a canine model

Br J Radiol. 2022 Jun 28:20220243. doi: 10.1259/bjr.20220243. Online ahead of print.

ABSTRACT

OBJECTIVE: To compare the technical efficacy and safety between prostatic artery occlusion (PAO) with ethylene vinyl alcohol copolymer (EVOH) and prostatic artery embolization (PAE) with microspheres in a canine model.

METHODS: 17 adult male beagles underwent PAO (n = 7) with Onyx-18 or PAE (n = 10) with microspheres (300-500 µm). After procedures, all dogs were inspected for procedure-related complications during 1 month follow-up. MRI evaluations were performed immediately before and 1 week, 2 weeks, and 1 month after procedures to document prostate volume (PV) and the prostate ischemia size. Differences between groups were statistically analyzed.

RESULTS: Both procedures were bilaterally successful in all animals. Although the mean procedure times were comparable in both groups, the mean fluoroscopy time (23.80 vs 36.24 min, p = 0.014) and radiation dose (68.19 vs 125.26 mGy, p = 0.003) were significantly less in PAO-group. Recanalization was observed more frequently in PAE than PAO at 1 month of follow-up. The mean percentage of PV change significantly decreased at 2 weeks and 1 month in both groups (30.71% vs 37.89% at 2 week, and 56.41vs 55.56% at 1 month, after PAO and PAE respectively), without significant differences between groups at either time point. There was a significant increase in the mean prostate ischemia induced by PAO in comparison with PAE at 1 week (43.44% vs 18.91 ml, p = 0.001). No major complications were observed except one animal after PAO with transient hematuria and acute urinary retention.

CONCLUSIONS: PAO with EVOH is technically feasible and with comparable efficacy and safety with PAE.

ADVANCES IN KNOWLEDGE: A new technical modification of the prostatic artery embolization (PAE) consisting of the use of liquid embolic agent to occlude the prostatic artery trunk and its branches has been developed in preclinical study, showing to be an effective and safe procedure which can induce a significant prostate shrinkage for the management of symptomatic BPH in patients. In addition, the findings have showed a similar therapeutic effect comparable with the conventional PAE using microspheres.

Empagliflozin for Heart Failure With Preserved Left Ventricular Ejection Fraction With and Without Diabetes

Circulation. 2022 Jun 28:101161CIRCULATIONAHA122059785. doi: 10.1161/CIRCULATIONAHA.122.059785. Online ahead of print.

ABSTRACT

BACKGROUND: Empagliflozin improves outcomes in patients with heart failure with a preserved ejection fraction, but whether the effects are consistent in patients with and without diabetes remains to be elucidated.

METHODS: Patients with class II through IV heart failure and a left ventricular ejection fraction >40% were randomized to receive empagliflozin 10 mg or placebo in addition to usual therapy. We undertook a prespecified analysis comparing the effects of empagliflozin versus placebo in patients with and without diabetes.

RESULTS: Of the 5988 patients enrolled, 2938 (49%) had diabetes. The risk of the primary outcome (first hospitalization for heart failure or cardiovascular death), total hospitalizations for heart failure, and estimated glomerular filtration rate decline was higher in patients with diabetes. Empagliflozin reduced the rate of the primary outcome irrespective of diabetes status (hazard ratio, 0.79 [95% CI, 0.67, 0.94] for patients with diabetes versus hazard ratio, 0.78 [95% CI, 0.64, 0.95] in patients without diabetes; Pinteraction=0.92). The effect of empagliflozin to reduce total hospitalizations for heart failure was also consistent in patients with and without diabetes. The effect of empagliflozin to attenuate estimated glomerular filtration rate decline during double-blind treatment was also present in patients with and without diabetes, although more pronounced in patients with diabetes (1.77 in diabetes versus 0.98 mL/min per 1.73 m2 in patients without diabetes; Pinteraction=0.01). Across these 3 end points, the effect of empagliflozin did not differ in patients with prediabetes or normoglycemia (33% and 18% of the patient population, respectively). When investigated as a continuous variable, baseline hemoglobin A1c did not modify the effects on the primary outcome (Pinteraction=0.26). There was no increased risk of hypoglycemic events in either subgroup as compared with placebo.

CONCLUSIONS: In patients with heart failure and a preserved ejection fraction enrolled in EMPEROR-Preserved (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Preserved Ejection Fraction), empagliflozin significantly reduced the risk of heart failure outcomes irrespective of diabetes status at baseline.

Split body comparative clinical and radiological study of fractional CO2 laser versus carboxytherapy in treatment of striae distensae

Dermatol Ther. 2022 Jun 28:e15668. doi: 10.1111/dth.15668. Online ahead of print.

ABSTRACT

BACKGROUND: Striae Distensae (SD) are quite common complaint in dermatology practice. They are linear lesions of variable length and width according to the site and the causative condition. Several treatment modalities have been tried. To achieve satisfactory results, a combination therapy is often needed.

OBJECTIVES: To evaluate the efficacy and safety of fractional CO2 laser versus carboxytherapy in the treatment of Striae Distensae clinically and radiologically.

METHODS: Thirty Egyptian patients with striae distensae, received a split body therapy: the left side was treated by fractional CO2 laser and the right side was treated by carboxytherapy in the same session. Six sessions were done with 4 weeks apart. Clinical evaluation by measurement of the width of widest striae on both sides, global aesthetic improvement scale (GAIS) and Likert satisfaction scale. Radiological evaluation by measurement of cutaneous thickness of widest striae on both sides by ultrasonography.

RESULTS: There was a highly statistically significant decrease in the median width of the widest striae distensae on both sides after the last session (P < 0.01). Regarding GAIS, satisfaction scale and ultrasound, there was highly statistically significant improvement on laser side than carboxytherapy side (P < 0.01) after last session.

CONCLUSION: Both fractional CO2 laser and carboxytherapy may be considered as safe and effective lines of treatment for striae distensae, but fractional CO2 laser showed excellent improvement clinically, radiologically when compared with carboxytherapy which made it a promising module in treatment of striae distensae.

Association between alcohol consumption and DNA methylation in blood: a systematic review of observational studies

Epigenomics. 2022 Jun 28. doi: 10.2217/epi-2022-0055. Online ahead of print.

ABSTRACT

Aim: We systematically reviewed and evaluated current literature on alcohol consumption and DNA methylation (DNAm) at the genome-wide and probe-wise level in blood of adults. Materials & methods: Five databases (PubMed, Embase, Web of Science, CINAHL and PsycInfo) were searched until 20 December 2020. Studies assessing the effect of alcohol dependence on DNAm were not eligible. Results: 11 cross-sectional studies were included with 88 to 9643 participants. Overall, all studies had a risk of bias criteria unclear or unmet. Epigenome-wide association studies identified between 0 and 5458 differentially methylated positions, and 15 were observed in at least four studies. Conclusion: Potential methylation markers for alcohol consumption have been identified, but further validation in large cohorts is needed.

Hepatitis B virus X gene impacts on the innate immunity and immune-tolerant phase in chronic hepatitis B virus infection

Liver Int. 2022 Jun 28. doi: 10.1111/liv.15348. Online ahead of print.

ABSTRACT

BACKGROUND & AIMS: The immunologic features involved in the immune-tolerant phase of chronic hepatitis B (CHB) virus (HBV) infection are unclear. The hepatitis B virus X (HBx) protein disrupts IFN-β induction by downregulating MAVS and may destroy subsequent HBV-specific adaptive immunity. We aimed to analyze the impacts of genetic variability of HBx in CHB patients on the immune-tolerant phase during long-term follow-up.

METHODS: Children with CHB in the immune-tolerant phase were recruited and followed longitudinally. HBx gene sequencing of infecting HBV strains was performed, and the effects of HBx mutations on the immune-tolerant phase were assessed. Restoration of the host immune response to end the immune-tolerant phase was investigated by immunoblotting, immunostaining, ELISA and reporter assays of MAVS/IFN-β signaling in liver cell lines, patient liver tissues and the HBV plasmid replication system.

RESULTS: A total of 173 children (median age, 6.92 years) were recruited. Patients carrying HBx R87G, I127V, and R87G+I127V double mutations exhibited higher cumulative incidences of immune-tolerant phase breakthrough (p=0.011, p=0.006, and p=0.017, respectively). Cells transfected with HBx R87G and I127V mutants and pHBV1.3-B6.3 replicons containing the HBx R87G and I127V mutations exhibited statistically increased level of IFN-β, especially under poly(I:C) stimulation or Flag-MAVS cotransfection. HA-HBx wild-type interacted with Flag-MAVS and enhanced its ubiquitination, but this ability was diminished in the R87G and I127V mutants.

CONCLUSIONS: HBx suppresses IFN-β induction. R87G and I127V mutation restored IFN-β production by preventing MAVS degradation, contributing to curtailing the HBV immune-tolerant phase in CHB patients.

A randomized controlled trial on long-term effectiveness of a psychosocial aftercare program following pediatric chronic pain treatment: Who benefits the most?

Eur J Pain. 2022 Jun 28. doi: 10.1002/ejp.1998. Online ahead of print.

ABSTRACT

BACKGROUND: For pediatric chronic pain patients, intensive interdisciplinary pain treatment (IIPT) is a well-established treatment. The treatment’s short-term effectiveness can be improved by an additive psychosocial aftercare (PAC). However, neither the program’s long-term effectiveness nor the patients in particular need have been investigated yet.

METHODS: This study aimed at determining the long-term effects of PAC and detecting predictors of treatment outcome within a multicenter randomized controlled trial measured at five time points up to twelve months after discharge. At inpatient admission to IIPT, patients (N=419, 14.3 years of age, 72.3% female) were randomly assigned to intervention or control group. After IIPT discharge, the intervention group received PAC, whereas the control group received treatment as usual (TAU). Patient-reported outcomes included pain and emotional characteristics. Clinicians assessed potential psychosocial risk factors and their prognosis of treatment outcome. Statistical analyses included mixed-models and univariable logistic regressions.

RESULTS: Data at the 12-month follow-up (n=288) showed a significant benefit of PAC compared with TAU; the majority (59.0%) of patients in the PAC-group reported no chronic pain compared to 29.2% of TAU-patients (p<.001). Patients with a single parent specifically benefited from PAC compared to TAU. Clinicians were able to make a reliable prognosis of treatment outcome, but did not successfully predict which patients would benefit the most from PAC.

CONCLUSIONS: Study results suggest that PAC is highly effective irrespective of patient characteristics, but particularly for patients with single parents. Its broad implementation could help to improve the long-term outcomes of youth with severely disabling chronic pain.

Nomogram predicting the probability of spontaneous stone passage in patients presenting with acute ureteric colic

BJU Int. 2022 Jun 28. doi: 10.1111/bju.15839. Online ahead of print.

ABSTRACT

OBJECTIVES: To develop a nomogram that could predict spontaneous stone passage (SSP) in patients presenting with acute ureteric colic who are suitable for conservative management.

SUBJECT/PATIENTS: A 2517 patient dataset was utilised from an international multi-centre cohort study (MIMIC, A Multi-centre Cohort Study Evaluating the role of Inflammatory Markers In Patients Presenting with Acute Ureteric Colic) of patients presenting with acute ureteric colic across 71 secondary care hospitals in the United Kingdom, Ireland, Australia, and New Zealand. Inclusion criteria mandated a non-contrast CT-KUB.

METHODS: SSP was defined as the ‘absence of the need for intervention’. The model was developed using logistic regression and backwards selection (to achieve lowest AIC) in a subset from 2009-2015 (n=1728) and temporally validated on a subset from 2016-2017 (n=789).

RESULTS: Of the 2517 patients, 1874 had SSP (74.5%). Mean age (±[SD]) was 47 (±14.7) years and 1892 were male (75.2%). At the end of the modelling process, gender: male (OR 0.8, 95%CI 0.64-1.01, p=0.07), neutrophil count (OR 1.03, 95%CI 1.00-1.06, p = 0.08), hydronephrosis (OR 0.79, 95%CI 0.59-1.05, p=0.1), hydroureter (OR 1.3, 95%CI 0.97-1.75, p =0.08), stone size >5-7mm (OR 0.2, 95%CI 0.16-0.25, p<0.0001), stone size >7mm (OR 0.11, 95%CI 0.08-0.15, p<0.001), middle ureter stone position (OR 0.59, 95%CI 0.43-0.81, p=0.001), upper ureter stone position (OR 0.31, 95%CI 0.25-0.39, p<0.001) ), medical expulsive therapy use (OR 1.36, 95%CI 1.1 – 1.67, p = 0.001), oral NSAID use (OR 1.3, 95%CI 0.99 – 1.71, p=0.06), and rectal NSAID use (OR1.17, 95%CI 0.9 – 1.53, p=0.24) remained. Concordance-statistic (C-statistic) was 0.77 (95%CI 0.75 – 0.80) and a nomogram was developed based on these.

CONCLUSION: The presented nomogram is available to use as an online calculator via www.BURSTurology.com and could allow clinicians and patients to make a more informed decision on pursuing conservative management versus early intervention.
