Thioredoxin reductase 1 (TXNRD1) and heme oxygenase-1 (HO-1) are both involved in the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway and play key roles in antioxidant responses. In patients with esophageal squamous cell carcinoma (ESCC), the correlation between the expression of these two proteins and the therapeutic response to neoadjuvant chemoradiation therapy (NACRT), as well as the difference in their expression after chemoradiotherapy, remains unknown.

Proteins involved in the Nrf2 pathway were immunolocalized in carcinoma cells in ESCC patients on NACRT with 5-fluorouracil and cisplatin, followed by esophagectomy. The 8-hydroxydeoxyguanosine (8-OHdG) levels were used to quantify reactive oxygen species. The changes in immunoreactivity before and after NACRT (Δ) were assessed.

Tumor reduction following NACRT was significantly attenuated in pre-therapeutic biopsy specimens associated with high HO-1 status. TXNRD1Δ, HO-1Δ, and 8-OHdGΔ were significantly different in the ineffective and effective groups. The overall survival was significantly lower in high Nrf2 and TXNRD1 groups. In addition, high TXNRD1 expression was an independent prognostic factor in the multivariate analysis of overall survival.

The study findings indicate that HO-1 status in pre-therapeutic biopsy specimens could predict response to NACRT, and TXNRD1 status could predict overall survival of ESCC patients.

Lumbo-sacral transitional vertebrae (LSTV) are accompanied by changes in soft tissue anatomy. The aim of our retrospective study was to evaluate the effects of LSTV as well as the number of free lumbar vertebrae on surgical approaches of ALIF, OLIF and LLIF at level L4/5.

We assessed the CTs of 819 patients. Of these, 53 had LSTV from which 11 had six (6LV) and 9 four free lumbar vertebrae (4LV). We matched them for sex and age to a control group.

Patients with LSTV had a higher iliac crest and vena cava bifurcation, a greater distance between the common iliac veins and an anterior translation of the psoas muscle at level L4/5. In contrast, patients with 6LV had a lower iliac crest and aortic bifurcation, no differences in vena cava bifurcation and distance between the iliac veins compared to the control group.

For patients with LSTV and five or four free lumbar vertebrae, the LLIF approach at L4/5 may be hindered due to a high riding iliac crest as well as anterior shift of the psoas muscle. Whereas y.
The British Orthopaedic Association (BOA) guidelines in managing supracondylar humerus fractures in children, outline indications for urgent fixation of these fractures. We present our data from a regional paediatric trauma centre before and after implementing a change in practice as per these guidelines.

Retrospective clinical audit against BOA guidelines. Radiographs, admission clerking notes, operation notes, and clinic letters were all reviewed. We included all displaced supracondylar fractures of the extension type (Gartland Types 2b and 3). The first audit cycle occurred in 2017, subsequent cycles in 2018 & 2019.

172 patients reviewed across the three audit stages. In the first audit, almost quarter of patients were operated on in the same night without clear indication as per the guidelines. This dropped down to 7% after a change of practice in 2019. Rate of conversion to open reduction and nerve complications did not increase after delayed fixation.

When there is no indication for same night operating out of hours, delaying treatment until the next day seems to be a safe way of treating these difficult fractures. Our data show that there is no increase in complications when these fractures are managed the next day.

Traumatic shoulder instability most frequently occurs in young people often during sports events. Currently, the arthroscopic Bankart repair is the therapy of choice in the absence of extensive glenoid bone loss and has proved to be a safe and effective procedure. Nevertheless, we see recurrence of instability-especially if new trauma happens-and further data are needed to guide the right decision-making for these often young patients. The purpose of this study was to determine the long-term outcome 10years after arthroscopic Bankart operation in terms of satisfaction of the patient, functional result, complications, recurrent instability, and development of osteoarthritis, and to look after possible risk factors for recurrence of instability and statistical proof of these.

Thirty-nine out of 49 patients underwent physical examination of both shoulders. We could perform a postoperative shoulder a-p X-ray in 28 patients. According to Samilson, [24] the extent of osteoarthritis was measured. The Constant scfying and functional very good long-term result-reflected by the Constant score. We assume that the extent of osteoarthritis seems to be the determining factor of the very good functional result, even though ongoing instability was present in 15.3% of the patients.

Scaphocephaly is the premature closure of the sagittal suture. The treatment strategies mainly focus on correcting the shape of the head, but there are very limited studies examining changes in brain structure. This study aimed to investigate shape differences in the shape of corpus callosum regarding the pre-treatment and post-treatment term at scaphocephaly patients.

Cranium shape data were collected from the two-dimensional digital images. The generalized Procrustes analysis was used to obtain mean shapes in the pre- and postoperative phases. The shape deformation of the corpus callosum from the pre- to postoperative phases was evaluated using the thin plate spline method.

There is an enlargement of the splenium part of corpus callosum in the late group. In the early group, corpus callosum genu and body enlargement were observed in the postoperative period compared to the preoperative period, followed by a narrowing of the isthmus region.

This study showed structural deformations in the corpus callosum in scaphocephaly patients using head shape with the landmark-based geometric morphometric method by taking into consideration the topographic distribution. An enlargement at the splenium part of corpus callosum exposes after the cranial vault expansion depending on time.

We investigated the inhibitory effects of captopril on matrix metalloproteinases (MMPs) and its effect as a primer on dentin bonding durability.

One hundred fifty human third molars were selected. Flat surfaces of the middle dentin were exposed, etched 15s, and followed by pretreatment with a primer for 60s, including distilled water (control, the negative control primer), 2% chlorhexidine digluconate (CHD,the positive control primer), and captopril solution. Inhibitory effects of primers on MMPs were evaluated by hydroxyproline and gelatinase activity tests. All primers were applied on dentin followed by bonding. Some of the samples were sliced into slabs, placed in a fluorescent solution containing gelatin, and incubated for in situ zymography. Some were cut into sticks, and after aging for 1day, 12months, or 24months, microtensile bonding strength was tested. Some were cut into slabs, aged for 1day, 12months, or 24months, and taken out for nanoleakage tests to reveal interface defects.

Hydroxyproline and gelatinase activity analyses showed that captopril exerted better inhibitory effects on MMPs, relative to 2% CHD (p < 0.05). A 0.2% captopril aqueous solution (0.2% CapW) was chosen to apply to the dentin. In situ zymography showed that inhibitory effects of captopril on gelatinase were significantly higher compared to 2% CHD (p < 0.01). Microtensile strength revealed that the bonding effects of the 0.2% CapW group lasted longer, compared to the control and 2% CHD groups (p < 0.05). Interface defects, detected by nanoleakage, were significantly reduced in the 0.2% CapW group, compared to the control and 2% CHD groups (p < 0.05).

Captopril inhibits dentin MMP activities and effectively improves dentin bonding durability.

Captopril is a promising dentin bonding primer for improving bonding durability.

To systematically review the literature on the efficacy of interdental cleaning devices (ICDs) used with active substances, as adjuncts to toothbrushing, in comparison with toothbrushing alone or with ICDs without active substances.

Searches for randomized clinical trials were performed in PubMed, Embase, Scopus, Cochrane (CENTRAL), and Web of Science. Two independent researchers performed study selection, data extraction, and risk-of-bias assessment; a third one resolved any disagreement. Meta-analysis was not feasible, and a narrative approach was used to synthesize the evidence.

Seven studies were included. Dental floss with chlorhexidine was used in five studies, whereas interdental brushes with chlorhexidine and cetylpyridinium chloride were used in one study each. ICDs with active substances resulted in significantly higher antiplaque and antigingivitis efficacies than without ICDs (n = 3). ICDs with and without active substances demonstrated contrasting results. For this comparison, six studies were included for each outcome. Significantly higher antigingivitis efficacy of ICDs with active substances was noted in four studies, whereas significantly higher antiplaque efficacy of ICDs with active substances was reported in three studies. All comparisons demonstrated a very low certainty of evidence.

There is no robust evidence for the additional clinical efficacy of ICDs with active substances regarding their antiplaque and antigingivitis efficacies. These devices may have additional clinical efficacy when compared with the absence of interproximal hygiene.

The use of ICDs helps maintain or achieve periodontal health. However, the adjunct use of active substances may not provide additional benefits.
