Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
BACKGROUND Although well accepted by clinicians and patients, teledentistry is not currently a widely used model of care within Australian public oral health services. This qualitative study aimed to review and evaluate dental clinicians' perceptions, by determining the acceptability and appropriateness of teledentistry as a model of care. METHODS A purposive sample of 12 public dental practitioners employed by a Local Health District in Sydney, and who had participated in teledentistry consultations, were recruited to participate in focus groups. Focus group discussions were transcribed verbatim and subjected to thematic analysis. RESULTS Teledentistry was a novel concept for most participants and was well accepted. Participants valued the use of a standardized consultation template as well as effective communication with other dental clinicians to support the practice of teledentistry. However, many found attempting contact with patients over the telephone difficult as well as the perceived patient frustration with the administration process and technological difficulties experienced. CONCLUSION Teledentistry has the potential for growth and expansion in the public health system. From the opinions in this study, the authors propose further research is needed into the efficacy of teledentistry to assist with the development of a model of care that would be beneficial for dental clinicians and their patients. © 2023 Australian Dental Association.

Germline-focused analysis of tumour-detected variants in 49,264 cancer patients: ESMO Precision Medicine Working Group recommendations. Ann Oncol 2023; 34:215-227.

Abstract
BACKGROUND The European Society for Medical Oncology Precision Medicine Working Group (ESMO PMWG) was reconvened to update its 2018/19 recommendations on follow-up of putative germline variants detected on tumour-only sequencing, which were based on an analysis of 17 152 cancers. METHODS We analysed an expanded dataset including 49 264 paired tumour-normal samples. We applied filters to tumour-detected variants based on variant allele frequency, predicted pathogenicity and population variant frequency. For 58 cancer-susceptibility genes, we then examined the proportion of filtered tumour-detected variants of true germline origin [germline conversion rate (GCR)]. We conducted subanalyses based on the age of cancer diagnosis, specific tumour types and 'on-tumour' status (established tumour-gene association). RESULTS Analysis of 45 472 nonhypermutated solid malignancy tumour samples yielded 21 351 filtered tumour-detected variants of which 3515 were of true germline origin. 3.1% of true germline pathogenic variants were absent from the filtered tumour-detected variants. For genes such as BRCA1, BRCA2 and PALB2, the GCR in filtered tumour-detected variants was >80%; conversely for TP53, APC and STK11 this GCR was <2%. CONCLUSION Strategic germline-focused analysis can prioritise a subset of tumour-detected variants for which germline follow-up will produce the highest yield of most actionable true germline variants. We present updated recommendations around germline follow-up of tumour-only sequencing including (i) revision to 5% for the minimum per-gene GCR, (ii) inclusion of actionable intermediate penetrance genes ATM and CHEK2, (iii) definition of a set of seven 'most actionable' cancer-susceptibility genes (BRCA1, BRCA2, PALB2, MLH1, MSH2, MSH6 and RET) in which germline follow-up is recommended regardless of tumour type.

Abstract
Periodontitis is a progressive disease that ultimately leads to bone and tooth loss. A major consequence of periodontal disease is the inability to regain lost bone in the periodontium. The importance was demonstrated of glucose-regulated protein-78 (GRP78) in the osteogenic differentiation of periodontal ligament stem cells and their potential use for regeneration of the periodontium. Previous studies have shown the relationship between GRP78 and dentine matrix protein-1 (DMP1). The importance of this receptor-ligand complex in supporting the process of osteogenesis and angiogenesis was confirmed in this study. To show the function of GRP78 in mineralised tissues, transgenic periodontal ligament stem cells (PDLSCs) were generated in which GRP78 was either overexpressed or silenced. Gene expression analysis of the cells cultured under osteogenic conditions showed an increase in key osteogenic genes with the overexpression of GRP78. RNA-Seq analysis was also performed to understand the transcriptome profile associated with genotype changes. Using the database for annotation, visualisation, and integration discovery (DAVID) for the functional enrichment analysis of differentially expressed genes, the upregulation of genes promoting osteogenesis and angiogenesis with GRP78 overexpression was demonstrated. Alizarin red staining and scanning electron microscopy analysis revealed matrix mineralisation with increased calcium deposition in GRP78 overexpressing cells. The in vivo osteogenic and angiogenic function of GRP78 was shown using a subcutaneous implantation rodent model. The results suggested that GRP78 in PDLSCs can regulate the expression of both osteogenesis and angiogenesis. Therefore, GRP78 could be considered as a therapeutic target for repair of diseased periodontium.

Abstract
Photocatalysis is found to be one of the best suited processes that respond to the purification of water systems and the semiconductor nanomaterials are learned to be incredible materials which carry out the photocatalytic process as they readily decompose the pollutants effectively. In this present work, CdSe nanoparticles belonging to II-VI group semiconductor compounds were synthesized using a facile hydrothermal process with different precursor concentrations and were analysed for various characterization studies such as X-ray diffraction (XRD), Transmission electron microscopy (TEM), UV-vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR) and Photoluminescence (PL) studies. The XRD study of the synthesized CdSe nanostructures revealed that the average crystallite size was ranging from 18.5 nm to 24 nm pointing out the increase in size with increase in molar concentrations. The morphological structure of synthesized CdSe samples exhibited urchin-like structure for a lower concentration with several rod-like projections appearing in diverse directions. These CdSe nano-urchins synthesized with lower concentrations are found suitable to carry out the process of photocatalytic activity. The process was carried out under visible light radiation for 180 min with aqueous solution of methylene blue (MB) as the ideal toxin to be degraded. The attained degradation efficiency was nearly 80% clearly displaying that the synthesized samples are good photocatalysts. By tuning the bandgap, through the optimization of the precursor concentrations, greater efficiency can be achieved in future.

Abstract
STUDY OBJECTIVES Obstructive sleep apnea is associated with neurobehavioral dysfunction, but the relationship between disease severity as measured by the apnea-hypopnea index and neurobehavioral morbidity is unclear. The objective of our study is to compare the neurobehavioral morbidity of mild sleep-disordered breathing versus obstructive sleep apnea. METHODS Children 3-12 years old recruited for mild sleep-disordered breathing (snoring with obstructive apnea-hypopnea index < 3) into the Pediatric Adenotonsillectomy Trial for Snoring were compared to children 5-9 years old recruited for obstructive sleep apnea (obstructive apnea-hypopnea 2-30) into the Childhood Adenotonsillectomy Trial. Baseline demographic, polysomnographic, and neurobehavioral outcomes were compared using univariable and multivariable analysis. RESULTS The sample included 453 participants with obstructive sleep apnea (median obstructive apnea-hypopnea index 5.7) and 459 participants with mild sleep-disordered breathing (median obstructive apnea-hypopnea index 0.5). By polysomnography, participants with obstructive sleep apnea had poorer sleep efficiency and more arousals. Children with mild sleep-disordered breathing had more abnormal executive function scores (adjusted odds ratio 1.96, 95% CI 1.30-2.94) compared to children with obstructive sleep apnea. There were also elevated Conners scores for inattention (adjusted odds ratio 3.16, CI 1.98-5.02) and hyperactivity (adjusted odds ratio 2.82, CI 1.83-4.34) in children recruited for mild sleep-disordered breathing. CONCLUSIONS Abnormal executive function, inattention, and hyperactivity were more common in symptomatic children recruited into a trial for mild sleep-disordered breathing compared to children recruited into a trial for obstructive sleep apnea. Young, snoring children with only minimally elevated apnea-hypopnea levels may still be at risk for deficits in executive function and attention.

Type of funding sources: None.
Background
In non-diabetic population, number of deaths increase as the post-challenge glucose spike (PGS) i.e. difference between the fasting and 2h-PG increases in the DECODE study.
Purpose
To assess whether PGS is a better predictor of post-ACS prognosis in patients without known diabetes.
Methods
Retrospective cohort analysis of post-MI survivors (n=1056) without known diabetes undergoing pre-discharge oral glucose tolerance test. A standardised dataset was collected for the Myocardial Infarction National Audit Project. MACE (death or non-fatal re-infarction) over 5 (median 3.4) years was collected from notes review. Predictors of MACE were determined from Cox proportional hazard regression (stepwise) models adjusted for several variables (tested for collinearity) including GRACE score (GRS), fasting (FG) and 2-hour post-load glucose (2hG) and PGS as % of the 2hG (%PGS) (VIF=3.12). Incremental predictive value of PGS over 2hG was tested using probabilities of MACE calculated from logistic regression models using the same covariates and FG, 2hG and PGS individually and in combination applying c-statistics, continuous net reclassification improvement (cNRI) and integrated discrimination improvement (IDI).
Results
Of the patients 469 (44.4%) had normal glucose tolerance, 378(35.8%) preDM and 209 (19.8%) had new DM. In the whole cohort, MACE was predicted by %PGS (HR 1.02 (1.01-1.03), p<0.0001), GRS (HR 1.01, (1.01-1.02), p<0.0001), discharge with betablockers (HR 1.50 (1.14-1.98), p=0.0037), previous history of MI (HR 1.44 (1.02-2.03), p=0.039) but neither FG nor 2hG were included in the final model. MACE was predicted by %PGS (HR 1.04 (1.02-1.06), p<0.0001) in the non-diabetic group but not in the new DM patients (HR 1.02 (0.99-1.05), p=0.296). Addition of PGS to models containing FG and 2hG improved reclassification by 22.6% for events and 5.0% for non-events (NRI>0 0.275, p<0.001) and discrimination (IDI 0.0076, p=0.033). However the c-statistics did not change significantly (ΔAUC 0.0094, p=0.099).
Conclusion
PGS is a better predictor of post-MI prognosis than FG or 2hG in patients without known diabetes.

Elliptical and linear relationships with rumen temperature support a homeorhetic trajectory for DMI during recovery of feedlot cattle exposed to moderate heat load. J Anim Sci 2022; 100:skac127.

Abstract
Most feedlot animals in Australia experience 2 to 3 moderate heat waves during summer. This study aimed to gain understanding of the physiological drivers in response to and during recovery from such events with a view to designing strategies to ensure rapid and safe recovery. Two hypotheses were tested during thermal challenge and recovery in climate-controlled rooms (CCR): firstly, the feedlot steer on a grain-based diet mounts appropriate physiological responses during moderate heat load and in recovery so that its performance and physiology state after recovery is not different to the feed restricted thermoneutral (FRTN) steer. Secondly, commonly used indicators of increased heat load, e.g., respiration rate (RR), panting score (PS), body surface temperatures (ST), and water consumption (WC), reflect rumen temperature (RT) during thermal challenge and recovery at the level of daily means. In this study, 36 Angus steers (live weight (LW) 451.5 ± 22.6 kg) made up 3 cohorts of 12 animals that sequentially underwent the CCR phase. For this 18-d phase, the steers were allocated to either a moderate heat load treatment (thermally challenged, TC, n = 18) or a FRTN treatment (n = 18). The TC group underwent 3 periods, Pre-Challenge (4 d, temperature humidity index (THI) range of 68 to 71), Challenge (7 d, THI 73 to 84 with diurnal cycling), and Recovery (7 d, THI 68 to 71). The FRTN group were held at thermoneutral conditions in the CCR (THI 66.9 ± 0.3), and each animal was offered an amount of feed was based on the feed intake of its LW matched TC pair. Thus, as DMI fell in the TC group during Challenge, feed restriction was imposed on the FRTN group. The data were collected by trained observers were DMI, RT, RR, PS, body STs (forehead, shoulder, leg, rump), and WC. Challenge induced a heat stress response in the TC group with reduced DMI and LW, and elevated RT, RR, PS, body STs, and WC (P < 0.001). These measures were unchanged or reduced in the FRTN group (P < 0.001). At the end of Recovery, the TC and FRTN groups had converged on most measures including LW. Daily mean RT of both groups showed strong linear relationships with THI, RR, PS, head ST, and WC (P ≤ 0.0022) but opposing elliptical relationships with DMI; that is, as DMI fell with increasing RT for the TC group, DMI increased with rising RT for the FRTN group. In all, the feedlot steers in this study demonstrated sufficient homeorhetic capacity to adjust to moderate heat load and recover from it.

Abstract
Presentation We present a case of spontaneous coronary artery dissection (SCAD) in a 35-year-old lady who was 4 months post-partum. Despite a lack of typical risk factors, initial presentation and investigations were strongly suggestive of ACS. Diagnosis Coronary angiography revealed an occluded proximal left anterior descending (LAD) artery with TIMI 0 flow. Angiographic appearances and intravascular ultrasound (IVUS) were consistent with SCAD. Treatment A single drug-eluting stent was deployed, successfully restoring good flow, without extending the dissection flap. Discussion SCAD should be considered as an important and underdiagnosed cause of ACS, predominantly in young women without other apparent risk factors.

Abstract
Abstract
Aim
According to GMC guidance, we are bound to discuss with close members of the patients to consider their views and reach the consensus of clinical management when patients lack capacity to make decisions. Our audit aimed to compare the practice of our institution against this guidance and instigate changes as necessary.
Method
We collected data of 30 randomly selected patients with dementia, undergoing emergency orthopaedic operations, from February to April 2021 in the first cycle. The data were collected from medical notes prospectively. The findings were presented in the local meeting. The implementations involved raising awareness of the GMC guidance among the members of the Trauma & Orthopaedics team by organizing a teaching session, creating posters, and sending an email from the clinical lead to the staff members to highlight the audit result. It was followed by the second audit cycle, which included 40 patients from June to August 2021.
Results
The first cycle revealed that there was only 36% compliance to the GMC guidance in our department, since only 9 out of the 30 cases had documentation about the discussion with the appropriate family member. The compliance rate of the second cycle (40 patients) saw a huge improvement up to 83%.
Conclusions
Significant improvement in documentation of the socially and medicolegally important discussion with the close contact of the patient was achieved. This was done by identifying the area which needed improvement and instigating changes in our department. Further audit loops will be conducted in due course to sustain this achievement.

Abstract
Matrix metalloproteinases (MMPs) have been implicated not only in the regulation of developmental processes but also in the release of biologically active molecules and in the modulation of repair during tertiary dentine formation. Although efforts to preserve dentine have focused on inhibiting the activity of these proteases, their function is much more complex and necessary for dentine repair than expected. The present review explores the role of MMPs as bioactive components of the dentine matrix involved in dentine formation, repair and regeneration. Special consideration is given to the mechanical properties of dentine, including those of reactionary and reparative dentine, and the known roles of MMPs in their formation. MMPs are critical components of the dentine matrix and should be considered as important candidates in dentine regeneration.

Abstract
Abstract
Aim
The COVID-19 pandemic has resulted in significant pressures on the NHS. Healthcare workers (HCWs) are at increased risk of infection. Personal protective equipment (PPE) lowers the risk of infection transmission. However, during the early phases of the pandemic, the information available regarding COVD-19 and the use of PPE has been unclear, with constantly changing guidelines. The aim of this study was to determine the knowledge and confidence about PPE usage among HCWs, in addition to measuring their anxiety levels during the COVID pandemic.
Method
A validated questionnaire was distributed among HCWs in as many UK hospitals as possible, during April 2020. The questionnaire consisted of 13 questions regarding demographics, knowledge on PPE guidance, HCW training and confidence levels in PPE usage and finally anxiety levels measured using the GAD-7 psychometric tool.
Results
1055 responses were received. Nurses (49%), Healthcare Assistants (HCA - 20%), Doctors (17%), Physios (8%) and other (6%). 99% of respondents indicated they were familiar with PPE guidance, but only 1.6% answered all 3 questions on PPE guidance accurately. 86.4% of respondents received mask-fitting checks. 79.7% received donning-doffing training. Despite this, only 46.8% were confident on their familiarity with PPE. 32.5% felt that their hospital communication regarding PPE policy during COVID-19 pandemic was poor or very poor. 30% HCWs experienced severe anxiety.
Conclusions
National guidance and local training on PPE usage during the COVID-19 pandemic has been unsatisfactory, leading to higher anxiety among HCWs. Improved information delivery and training are essential in preparation for the second wave and future pandemics.

Abstract
Abstract
Intra uterine devices (IUDs) is one of the most effective form of contraception available today. Uterine perforation and IUD migration is a rare but serious complication and is reported to occur in 0.05 to 13 cases out of 1000 IUCD placements. Migration of IUD to pelvis and lower abdominal organs following uterine perforation has been reported widely in literature. However far migration into the upper abdomen in very rare. Here we report a case asymptomatic peri-pancreatic migration of IUD.
A 65-year-old lady being investigated for pneumonia was picked up to have an asymptomatic IUD lying in front of the pancreas. The patient recalled having a hormonal Mirena coil placed 12 years previously for menopausal symptoms. Routine 3-year general practitioner follow-up failed to detect the IUD on vaginal examination. The patient denied spontaneous IUD discharge. However, three subsequent pelvic ultrasound scans did not detect any retained IUD and she was discharged as unrecognized IUD expulsion. She remained asymptomatic for the next 12 years with no abdominal symptoms though she did report to the General Practitioner, multiple episodes of new onset hot flushes when opening bowels - which was managed conservatively with reassurance.
It was decided to surgically remove the IUD. Intraoperatively, the IUD was found densely adherent to the lesser omentum close to the pancreas and stomach and was removed safely laparoscopically. The patient made a good postoperative overnight recovery and was discharged.
Intra-abdominal migration of IUDs is a very rare complication of IUD insertion and when detected should be promptly treated with Laparoscopic removal.

Abstract
Biomineralization of enamel, dentin, and bone involves the deposition of apatite mineral crystals within an organic matrix. Bone and teeth are classic examples of biomaterials with unique biomechanical properties that are crucial to their function. The collagen-based apatite mineralization and the important function of noncollagenous proteins are similar in dentin and bone; however, enamel is formed in a unique amelogenin-containing protein matrix. While the structure and organic composition of enamel are different from those of dentin and bone, the principal molecular mechanisms of protein-protein interactions, protein self-assembly, and control of crystallization events by the organic matrix are common among these apatite-containing tissues. This review briefly summarizes enamel and dentin matrix components and their interactions with other extracellular matrix components and calcium ions in mediating the mineralization process. We highlight the crystallization events that are controlled by the protein matrix and their interactions in the extracellular matrix during enamel and dentin biomineralization. Strategies for peptide-inspired biomimetic growth of tooth enamel and bioinspired mineralization of collagen to stimulate repair of demineralized dentin and bone tissue engineering are also addressed.

Abstract
Sleep-disordered breathing (SDB) is common in Chiari Malformation (CM) and Spina Bifida (SB) and can lead to adverse consequences if untreated. Therefore, screening is very important but the Pediatric Sleep Questionnaire (PSQ) has not been validated in this population. Further, there is limited data on the validity of this tool in children with central nervous system malformations. Retrospective chart review of CM and SB patients evaluated in our sleep center between 2008 and 2018. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the PSQ and several of its components were calculated to predict obstructive sleep apnea (OSA). A total of 149 patients met criteria for analysis. The majority were referred to a sleep specialist due to concern for SDB. OSA was found in 36% (53/149) of all patients. The sensitivity and specificity of the PSQ to predict OSA was 73.58% and 20.83%, respectively. The PPV was 33.91%, and the NPV was 58.82%. Specificity values were higher for PSQ as negative predictors of moderate or severe OSA. In this population, the sensitivity of PSQ for OSA is reasonable but lower than values described in other populations. The specificity and NPV are low. Even with a high prevalence of OSA, symptoms of SDB may overlap with those of other comorbidities leading to a low specificity. A PSQ could be used to prioritize which patients need a PSG more urgently than others. Further studies are needed to define an optimal cut-off value of the PSQ in this population.

Abstract
Abstract
Introduction
It has been shown that direct fixation of the posterior malleolus improves functional outcomes. Our aim was to audit the functional outcome of patients with these fractures which were fixed with an isolated posterolateral approach.
Method
A consecutive case series of patients who underwent direct fixation of the posterior malleolus using a posterolateral approach between 20/12/2012 and 23/1/2020 was identified. Fractures were classified according to Mason and Molloy classification based on preoperative CT. Type 2a and 2b fractures were included. Functional outcome was assessed using Olerud-Molander score.
Result
18 patients were included. Mean age at time of surgery was 52 years (range 20 to 75 years). 56% (n = 10) were female. Mean follow up was 18.1 months (range 4.2 months to 7.2 years). OMAS score for type 2a fractures (n = 9) was 71.1 (95% CI 65.3 to 77.0). OMAS score for type 2b fractures (n = 9) was 67.8 (95% CI 54.6 to 81.0). There was no significant difference between groups (p = 0.65).
Conclusions
Fixation of Mason and Molloy Type 2 fractures using an isolated posterolateral approach results in satisfactory functional results for the majority of patients. Further prospective comparative study is needed to identify which patients benefit most from alternative approaches.

Abstract
Abstract
Background
Post-prandial plasma glucose spikes contribute to the progression of atherosclerosis. Glycaemic variability may predict post-ACS prognosis. A third to two-thirds of these patients had diabetes mellitus (DM). Post-ACS prognosis is worse in DM than in those without. This has not been tested in patients without DM.
Purpose
To test whether post-load spike in plasma glucose in patients without known or newly diagnosed DM adversely affects prognosis.
Methods
Retrospective cohort analysis of 847 MI survivors without known or newly diagnosed DM who were followed up for MACE (death and non-fatal MI). The median post-glucose spike (PGS, defined as the difference between the 2h-PG and FPG) was 2.4 mmol/l for the whole cohort and 1.5 mmol/l for the patients with normal glucose tolerance (NGT). Group 1: PGS ≤2.4 mmol/l and Group 2: PGS >2.4 mmom/l were compared using Mann-Whitney test for continuous variables and chi-squared test for categorical variables. Event free survival in the two groups was estimated from the Kaplan–Meier curves and compared using log-rank test. Cox proportional hazard regression identified predictors of MACE. Continuous net reclassification improvement (NRI>0) and integrated discrimination improvement (IDI) and c-statistics determined the added predictive value of glycaemic matrices
Results
MACE was higher in group 2 (OR 1.99, 95% CI 1.36 to 2.91, p=0.0004) compared to group 1. In patients with NGT, MACE was higher in patients with PGS ≥1.5 mmol/l vs those below (OR 2.37, 95% CI 1.31 to 4.26, p=0.0041). Event free survival was worse in pre-diabetes than in the NGT groups (HR 1.57, 95% CI 1.17 to 2.12, p=0.003). and in group 2 than 1 (HR 2.01, 95% CI 1.49 to 2.71, p<0.001). Amongst the patients with NGT, event free survival was worse in patients with PGS ≥1.5 mmol/l (HR 2.09, 95% CI 1.35 to 3.25, p<0.001). PGS independently predicted MACE in the whole cohort (HR 1.16, 95% CI 1.06 to 1.26, p=0.002) and NGT group (HR 2.06, 95% 1.51 to 2.79, p<0.000). Group 2 independently predicted MACE in the whole cohort (HR 1.75, 95% CI 1.26 to 2.42, p<0.001). In the NGT group, PGS >median, independently predicted of MACE (HR 2.67, 95% CI 1.54 to 4.61, p<0.001). The c-statistic a model containing GRS only increased on addition of PGS (δAUC 0.0134, p=0.046) but not on addition of FPG. Within the whole cohort, PGS improved the net reclassification by 28% when added to the model containing GRS only. NGT cohort had higher net improvement at 46.6%. Addition of PGS to the model containing GRS and FPG resulted in NRI>0 of 25.5% in the whole cohort and 56.3% in the NGT cohort. Similar changes were seen in the IDI.
Conclusion(s)
PGS predicts post MI prognosis in patients without known or newly diagnosed DM including in patients with NGT. This suggests that PGS is a more powerful indicator of post-MI prognosis than FPG

Abstract
Abstract
Background
Type 2 diabetes mellitus (DM) and pre-DM, newly diagnosed after MI in patients without known DM adversely affects prognosis. 2-hour post-load glucose (2h-PG) predicts post-MI prognosis better than fasting plasma glucose (FPG). Plasma glucose below the conventional threshold for the diagnosis of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT), affects post-MI prognosis.
Purpose
To test whether high-normal post-load plasma glucose in patients with normal glucose tolerance (NGT) would affect post-MI prognosis and whether FPG or 2h-PG increases this risk.
Methods
Retrospective cohort analysis of 425 MI survivors without known DM and with NGT followed up for (death and non-fatal MI) as MACE. MACE in patients with 2h-PG > median for the whole cohort (Group 2), was compared with those at or below (Group 1). Event free survival in the two groups was estimated from the Kaplan–Meier curves and compared using log-rank test. Cox proportional hazard regression identified predictors of MACE. Continuous net reclassification improvement (NRI>0) and integrated discrimination improvement (IDI) and c-statistics determined the added predictive value of glycaemic matrices.
Results
Median 2h-PG was 6.3 mmol/l. 219 patients in Group 1 and 206 in Group 2. Group 2 had higher age, prevalence of hypertension, hypercholesterolaemia, ST-segment depression and higher heart rate and GRACE scores. Median follow-up was 40.6 months. MACE was more frequent in Group 2 than Group 1 (OR 2.82, 95% CI 1.55 to 5.16, p<0.001). MACE-free survival was higher in Group 1 (HR 2.43, 95% CI 1.53 to 3.85, p<0.001). Group 2 (HR 2.42, 95% CI 1.44 to 4.04, p<0.001) predicted the MACE-free survival. 2h-PG, but not the FPG independently predicted of MACE (HR 1.73, 95% CI 1.31 to 2.30, p<0.001). Addition of 2h-PG to models containing FPG and other variables improved their predictive performance (NRI>0 0.5062, p<0.001; IDI 0.0376, p=0.003). The c-statistic increased when 2h-PG was added to the GRACE score only model (δAUC 0.037, 95% CI 0.012 to 0.081, p=0.046).
Conclusion(s)
This study suggests that “high-normal” 2h-PG is an independent predictor of post-MI prognosis. Normoglycaemic patients with 2h-PG ≥6.4 mmol/l, had worse post-MI prognosis compared to those with 2h-PG ≤6.3 mmol/l. The risk of MACE increased with increasing 2h-PG within the normal range. FPG had no effect on prognosis.

Abstract
Abstract
Background
Diabetes increases the risk of periodontal disease, which in turn negatively impact on diabetes control and complications. Therefore, awareness about the diabetes-oral health link and dental problems is important for people with diabetes. This study aimed to assess self-reported oral health status and knowledge of people living with diabetes.
Methods
A survey was conducted among patients who attended four public diabetes clinics in Sydney, Australia. The questionnaire included 10 knowledge items and a validated Oral Health Impact Profile (OHIP-14) scale. A convenience sample of 200 patients were recruited. The data were analysed using SPSS software with descriptive and Pearson's Chi-Squared tests reported.
Results
The mean age of participants was 62.4(±13.5) years. More than half were males (54.5%), born overseas (64%), not working (73%) and had type 2 diabetes (88%). More than half (55.1%) of the patients reported having one or more dental problems and this was negatively associated with their oral health-related quality of life (p < 0.001). The most common dental problems were: gaps between teeth, pain in teeth and dry mouth. Only 46.2% of the participants had adequate oral health knowledge (> the mean correct score 5.2 (±2.6). The main areas with poor knowledge were around the impact of gum disease on blood glucose levels (29.6%), effects of dry mouth on tooth decay (33.8%) and the link between diabetes and teeth and gums (44.5%). Only 13% of the patients reported receiving oral health information from diabetes care providers (diabetes educator, general practitioner/diabetes specialist and dietitian/nutritionist). Receiving oral health information was found to be significantly associated with higher oral health knowledge scores (p < 0.05).
Conclusions
Considering that a majority of patients with diabetes have dental problems and inadequate oral health knowledge, diabetes care providers should take the opportunity to educate patients about oral health risks.
Key messages
People living with diabetes found to have dental problems and inadequate oral health knowledge. Considering that diabetes and dental problems adversely affect each other, it is crucial to educate patients about good oral hygiene and regular dental visit.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
It is increasingly common in oncology practice to perform tumour sequencing using large cancer panels. For pathogenic sequence variants in cancer susceptibility genes identified on tumour-only sequencing, it is often unclear whether they are of somatic or constitutional (germline) origin. There is wide-spread disparity regarding both the extent to which systematic 'germline-focussed analysis' is carried out upon tumour sequencing data and for which variants follow-up analysis of a germline sample is carried out. Here we present analyses of paired sequencing data from 17 152 cancer samples, in which 1494 pathogenic sequence variants were identified across 65 cancer susceptibility genes. From these analyses, the European Society of Medical Oncology Precision Medicine Working Group Germline Subgroup has generated (i) recommendations regarding germline-focussed analyses of tumour-only sequencing data, (ii) indications for germline follow-up testing and (iii) guidance on patient information-giving and consent.

Abstract
Abstract
Introduction
Kleine-Levin syndrome (KLS) is a central disorder of hypersomnolence characterized by recurrent episodes of excessive sleepiness and sleep duration, along with varying degrees of cognitive dysfunction, altered perception, disinhibited behaviors, and eating disorders. Individuals with KLS are reported to be asymptomatic between episodes. KLS has a male preponderance with symptom onset typically during adolescence. A genetic basis has been suggested due to clustering of cases in certain ethnic populations and families. Purported triggers include viral infections, physical exertion, head trauma, and sleep deprivation.
Report of Case
A 15-year old male developed sudden-onset hypersomnolence with sleep duration of 20-23 hours per day. While awake, he had altered mentation and personality changes; parents reported aggression, hypersexual behaviors, hyperphagia, and derealization. During this 2-week episode, he underwent an extensive, yet unrevealing work-up and eventually experienced symptom resolution. Over 16 months, he has had 5 discrete episodes of hypersomnolence with abnormal wake behaviors, all preceded by viral illnesses and/or significant physical exertion and felt to be consistent with KLS. He has reported ongoing, albeit less severe, excessive daytime sleepiness between episodes. Polysomnography and multiple sleep latency testing, both performed while asymptomatic, were largely unremarkable. As episodes have decreased in duration and intensity over time, trials of lithium and stimulant therapy have been deferred per family preference, though the patient was started on a short course of azithromycin during his last episode for anti-inflammatory properties. Notably, the patient has developed significant anxiety due to fear of recurrence and is now engaged in therapy.
Conclusion
KLS is a rare disorder that tends to have shorter and less severe manifestations over time. To date, very few systematic studies have been done to evaluate potential treatments, such as lithium and macrolide therapy. Avoidance of triggers and adequate sleep are encouraged, and mental health support should also be considered.

Variations in the retromandibular approach to the condyle-transparotid versus anteroparotid transmasseteric - a prospective clinical comparative study. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2019; 121:14-18. [PMID: 31271891 DOI: 10.1016/j.jormas.2019.06.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Revised: 06/24/2019] [Accepted: 06/26/2019] [Indexed: 11/15/2022]
Abstract
BACKGROUND The management of mandibular condylar fracture remains controversial many surgeons still favour the open reduction and internal fixation (ORIF) which provides good result and immediate functioning as compared to closed reduction. With proven consensus for ORIF, dilemma remains in choosing the surgical approach to condyle due to proximity of complex and important anatomic structure. Various extra-oral surgical approaches are available for ORIF including preauricular, submandibular, retromandibular, transmasseteric anteroparotid etc. Variations in retromandibular approach such as transparotid, retro-parotid and anteroparotid are reported in literature. In our study we compared the retromandibular transparotid and retromandibular anteroparotid transmasseteric variations. METHODOLOGY Thirty condylar fracture in 26 patients, 15 in each group (group A - Retromandibular transparotid approach & group B - Retromandibular anteroparotid approach) were treated under general anaesthesia with naos-tracheal intubation and by the same surgeon having 20 years of experience in maxillofacial surgeries. We evaluated time taken for the procedure, amount of bone exposure, intra-operative haemorrhage. Postoperative presence of infection, sinus and fistula formation at the incision site, parotid fistula formation, facial nerve functioning using House-Brackman scale in immediate postoperative period, 3rd month postoperatively and 6 month postoperatively. RESULT The mean average time taken for group A was 78.2minutes and mean average time taken for group B was 64.8minutes. None of the patient had haemorrhage intra-operatively in both the groups. Exposure was sufficient in both the groups with same length of the incision. None of the patient suffered from postoperative infection in both the groups. Parotid fistula formation was present in 2 patients in group A while none of the patient had parotid fistula in group B. Three patients out of 15 had the transient facial nerve weakness in group A which got resolved in 6 month while none of the patient had facial nerve weakness in group B. All patients had adequate mouth opening with no occlusal discrepancies. CONCLUSION Retromandibular anteroparotid approach as described in this study has proven to be an extremely useful approach provides good access, and associated with minimal complications and morbidity compare to retromandibular transparotid approach. It is hence safe to say that this approach is relatively useful for an inexperienced and novice surgeon as well.

Abstract
The aim of this study was to investigate the antiviral property of Eurycoma longifolia Jack (EL) against dengue virus. A propriety standardized extract of Eurycoma longifolia Jack (Physta®) was tested for anti-viral activity after viral adsorption in Vero cell line. Viral yield was measured by qRT-PCR in four serotypes of dengue virus. The antiviral activity was further investigated in an in vivo AG129 mouse model for dengue inhibitory candidates. 100 mg/kg EL extract was fed twice daily and challenged with a lethal dose of (~1x105 PFU per mouse) of DENV-2 over a period of six days. Antiviral activity with IC50 of 33.84, 33.55, 58.35 and 119 µg/ml for DENV-1, DENV-2, DENV-3 and DENV-4 serotypes respectively was observed. The selectivity index (SI) values determined as the ratio of cytotoxic concentration (CC50) to inhibitory concentration (IC50) was the lowest for DENV-2 at 28.9. The dengue virus (DENV) replication measured by qRT-PCR showed a reduction of 100% for DENV-1, DENV-2, DENV-3 and 80% for DENV-4 at day 2 of exposure. In the in vivo AG129 mouse model, a lower weight reduction, 30% lower viral load and 12% higher platelet in the extract group compared to the control was observed at day 6. The extract of E. longifolia has potential anti-dengue properties with improving trends in platelet counts. E. longifolia supplementation is potentially a two-pronged approach in treating dengue fever.
