Road traffic collisions (RTC) are known to be one of the major causes of maxillofacial trauma (MFT). The road user factor is of crucial importance in the prevalence, severity, and treatment of maxillofacial injuries. The aims of the study were to determine the prevalence of maxillofacial trauma among road users, to illustrate injury patterns and to identify road users at high risk.

This historical prospective multi-center study was based on Israel's Trauma Registry between 2008-2018, which included 4829 hospitalized patients following RTC with MFT. Data were analyzed according to six road user types (vehicle driver, passenger, bicyclist, motorcyclist, pedestrian, and e-bike/scooter), maxillofacial injury location, and maxillofacial treatment.

MFT, which accounted for 5% of the hospitalized RTC injuries, was not equally distributed among road users, as bicyclists and e-bike/scooters were more prone to maxillofacial trauma (7.2% and 10.1%, respectively) than vehicle drivers (3.2%). Children (age 0-14years) comprised almost half of the cyclists, 25% of the pedestrians and 20% of the passengers. Some MFT patients experienced multiple injuries, with the majority involving jaw and facial bones and to a lesser extent the mouth, teeth, gingivae, and alveolar bone (mouth and dento-alveolar (DA) trauma). Approximately 30% of hospitalized road casualties with MFT underwent MF surgery, with the need for surgery lowest among pedestrians.

Hospitalized road casualties had different types of MFT in terms of prevalence, location, severity, and treatment, depending on the road user type.

The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014.

In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as Grade 1 (strong) or Grade 2 (weak) according to the concepts of the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.

The 31 CQs covered the six topics (a) prophylactic treatment, (b) diagnosis, (c) biliary drainage, (d) surgical treatment, (e) chemotherapy, and (f) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded.

This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

The prognosis of hyperproliferative skin lesions, such as psoriasis, basal cell carcinoma, and non-melanoma skin cancers, is significantly benefited from the levels of tazarotene-induced gene-1 (TIG3) expression and subsequent treatment with tazarotene. Such observations suggest that TIG3 could be used as a biomarker for apoptosis, differentiation, and proliferation. The current study aimed to evaluate the expression of TIG3 in normal oral mucosa (NOM) and oral squamous cell carcinoma (OSCC) compared with normal skin (NS) and skin squamous cell carcinoma (SSCC) using immunohistochemistry.

Seventeen cases each of SSCC, OSCC, NOM, and NS were evaluated. Each section was immunohistochemically stained with a rabbit polyclonal TIG3 antibody. The entire procedure was blinded and evaluated by 5 observers. Statistical analysis was performed using the chi-square test.

There was a significant decrease in TIG3 protein expression in OSCC and SSCC compared with that in NOM and NS (P=0.008). The progressive loss of expression was observed as the grade of both malignancies increased. However, there was no significant difference in the expression among the normal tissue groups and within SCC groups of similar grades.

The present study suggests that the loss of TIG3 is an important event in carcinogenesis. TIG3 acts as a regulator of keratinocyte proliferation and terminal differentiation. Therefore, TIG3 could be a potential biomarker to differentiate aggressive and non-aggressive neoplasms.

To evaluate the effect of the probiotic Lactobacillus brevis CD2 on the prevention of early traumatic oral lesions induced by a fixed orthodontic appliance.

Twenty orthodontic patients (14-57 yo) were recruited from a private clinic.

In a phase 2, double-blind clinical trial, all patients were randomly allocated (11 ratio) to a 21-day course of soluble tablets containing L brevis CD2 (4 billion colony-forming units after breakfast, lunch and dinner) or placebo, starting at the day of orthodontic appliance placement. The primary outcomes were days with oral lesions and lesion-related pain [ranging between 0 (no pain) and 10 (maximum pain)]. Oral health-related quality of life was measured using OHIP-14 before and after treatments.

All patients completed the study. Ten were treated with L brevis (28.1±13.3 yo, 70% women), and 10 received placebo (27.5±9.1 yo, 60% women). The oral lesions lasted significantly less time (P=.018) in patients treated with L brevis (2.5±1.0days) than with placebo (4.9±3.0days). Pain score was significantly lower (P=.039) when L brevis was used [median (min-max) 0 (0-4) vs. 3 (0-5)]. OHIP-14 scores were not significantly different between treatments.

Lactobacillus brevis CD2 reduced almost 50% the persistence of traumatic oral lesions in patients with fixed orthodontics. Yet, there was no improvement in quality of life compared to placebo, suggesting that such differences in persistency and pain related to oral lesions may be considered clinically irrelevant.

Pathogenic variants in the MT-TL1 gene result in mitochondriopathy in humans. The m.3250T>C variant in the MT-TL1 gene has been previously associated with exercise intolerance and mitochondrial myopathy, yet disease classification for this variant has not been consistently reported. Molecular studies suggest the m.3250T>C variant does not alter tRNALeu(UUR) structure but may have a modest impact on aminoacylation capacity. However, functional studies are limited. Our study aimed to further define the clinical presentation, inheritance pattern, and molecular pathology of the m.3250T>C variant. Families with the m.3250T>C variant were recruited from the Mitochondrial Disease Clinic at Cincinnati Children's Hospital Medical Center and GeneDx laboratory database. Affected individuals most frequently presented with cardiac findings, exercise intolerance, and muscle weakness. Hypertrophic cardiomyopathy was the most frequent cardiac finding. Many asymptomatic individuals had homoplasmic or near homoplasmic levels of the m.3250T>C variant, suggesting the penetrance is incomplete. Patient-derived fibroblasts demonstrated lowered ATP production and increased levels of reactive oxygen species. Our results demonstrate that the m.3250T>C variant exhibits incomplete penetrance and may be a possible cause of cardiomyopathy by impacting cellular respiration in mitochondria.There are no studies which have compared the risk of severe COVID-19 and related mortality between transplant recipients and nontransplant patients. We enrolled two groups of patients hospitalized for COVID-19, that is, kidney transplant recipients (KTR) from the French Registry of Solid Organ Transplant (n = 306) and a single-center cohort of nontransplant patients (n = 795). An analysis was performed among subgroups matched for age and risk factors for severe COVID-19 or mortality. Severe COVID-19 was defined as admission (or transfer) to an intensive care unit, need for mechanical ventilation, or death. Transplant recipients were younger and had more comorbidities compared to nontransplant patients. They presented with higher creatinine levels and developed more episodes of acute kidney injury. After matching, the 30-day cumulative incidence of severe COVID-19 did not differ between KTR and nontransplant patients; however, 30-day COVID-19-related mortality was significantly higher in KTR (17.9% vs 11.4%, respectively, p = .038). Age >60 years, cardiovascular disease, dyspnea, fever, lymphopenia, and C-reactive protein (CRP) were associated with severe COVID-19 in univariate analysis, whereas transplant status and serum creatinine levels were not. Age >60 years, hypertension, cardiovascular disease, diabetes, CRP >60 mg/L, lymphopenia, kidney transplant status (HR = 1.55), and creatinine level >115 µmol/L (HR = 2.32) were associated with COVID-19-related mortality in univariate analysis. In multivariable analysis, cardiovascular disease, dyspnea, and fever were associated with severe disease, whereas age >60 years, cardiovascular disease, dyspnea, fever, and creatinine level>115 µmol/L retained their independent associations with mortality. KTR had a higher COVID-19-related mortality compared to nontransplant hospitalized patients.Donor-acceptor (D-A) polymers are promising materials for organic electrochemical transistors (OECTs), as they minimize detrimental faradaic side-reactions during OECT operation, yet their steady-state OECT performance still lags far behind their all-donor counterparts. We report three D-A polymers based on the diketopyrrolopyrrole unit that afford OECT performances similar to those of all-donor polymers, hence representing a significant improvement to the previously developed D-A copolymers. 2',3'-cGAMP price In addition to improved OECT performance, DFT simulations of the polymers and their respective hole polarons also reveal a positive correlation between hole polaron delocalization and steady-state OECT performance, providing new insights into the design of OECT materials. Importantly, we demonstrate how polaron delocalization can be tuned directly at the molecular level by selection of the building blocks comprising the polymers' conjugated backbone, thus paving the way for the development of even higher performing OECT polymers.
