Universal germline testing among patients with colorectal cancer: clinical actionability and optimised panel.

PURPOSE: Universal germline testing in patients with colorectal cancer (CRC) with a multigene panel can detect various hereditary cancer syndromes. This study was performed to understand how to choose a testing panel and whether the result would affect clinical management. METHODS: We prospectively enrolled 486 eligible patients with CRC, including all patients with CRC diagnosed under age 70 years and patients with CRC diagnosed over 70 years with hereditary risk features between November 2017 and January 2018. All participants received germline testing for various hereditary cancer syndromes. RESULTS: The prevalence of germline pathogenic variants (PVs) in cancer susceptibility genes was 7.8% (38/486), including 25 PVs in genes with high-risk CRC susceptibility (the minimal testing set) and 13 PVs in genes with moderate-risk CRC susceptibility or increased cancer risk other than CRC (the additional testing set). All the clinically relevant PVs were found in patients diagnosed under age 70 years. Among them, 11 patients would not have been diagnosed if testing reserved to present guidelines. Most (36/38) of the patients with PVs benefited from enhanced surveillance and tailored treatment. PVs in genes from the minimal testing set were found in all age groups, while patients carried PVs in genes from the additional testing set were older than 40 years. CONCLUSION: Universal germline testing for cancer susceptibility genes should be recommended among all patients with CRC diagnosed under age 70 years. A broad panel including genes from the additional testing set might be considered for patients with CRC older than 40 years to clarify inheritance risks. TRIAL REGISTRATION NUMBER: NCT03365986.

1.3 µm wavelength tunable single-mode laser arrays based on slots.

Two twelve-channel arrays based on surface-etched slot gratings, one with non-uniformly spaced slots and another with uniformly spaced slots are presented for laser operation in the O-band. A wavelength tuning range greater than 40 nm, with a side-mode suppression ratio (SMSR) > 40 dB over much of this range and output power greater than 20 mW, was obtained for the array with non-uniform slots over a temperature range of 15 °C - 60 °C. The introduction of multiple slot periods, chosen such that there is minimal overlap among the side reflection peaks, is employed to suppress modes lasing one free spectral range (FSR) from the intended wavelength. The tuning range of the array with uniformly spaced slots, on the other hand, was found to be discontinuous due to mode-hopping to modes one FSR away from the intended lasing mode which are not adequately suppressed. Spectral linewidth was found to vary across devices with the lowest measured linewidths in the range of 2 MHz to 4 MHz.

Increased soil moisture aggravated the competitive effects of the invasive tree Rhus typhina on the native tree Cotinus coggygria.

BACKGROUND: Invasive exotic species have caused significant problems, and the effects of extreme precipitation and drought, which might occur more frequently under the global climate change scenarios, on interspecific relationship between invasive and native species remain unclear. RESULTS: We conducted a greenhouse experiment with three soil water levels (30-40%, 50-60%, and 70-80% of field capacity) and two cultivation treatments (monoculture pots, one seedling of either species and mixture pots, one seedling of each species) to investigate soil water content effects on the relationship between invasive Rhus typhina and native Cotinus coggygria. Rhus typhina had lower height but bigger crown area than C. coggygria in the monoculture treatment. Rhus typhina had higher height, bigger crown area and total biomass than C. coggygria in the mixture treatment. Drought decreased the growth parameters, total chlorophyll concentration, and leaf biomass, but did not change gas exchange and other biomass parameters in R. typhina. The growth parameters, leaf area index, biomass parameters, total chlorophyll concentration, and net photosynthetic rate of C. coggygria decreased under drought conditions. The log response ratio (lnRR), calculated as ln (total biomass of a target plant grown in monoculture/total biomass of a target plant grown in mixed culture), of R. typhina was lower than that of C. coggygria. The lnRR of R. typhina and C. coggygria decreased and increased with increase in soil water content, respectively. CONCLUSIONS: Rhus typhina has greater capacity to relatively stable growth to the drought condition than C. coggygria and has strong competition advantages in the mixture with C. coggygria, especially in the drought condition. Our study will help understand the causes of invasiveness and wide distribution of R. typhina under various moisture conditions and predict its expansion under climate change scenarios.

Crosstalk between PKC and MAPK pathway activation in cardiac fibroblasts in a rat model of atrial fibrillation.

OBJECTIVE: Atrial fibrillation (AF) is the most frequent form of cardiac arrhythmia and major cause of cardiac ischemia. Defective calcium homeostasis due to anomalous expression of ryanodine receptor type 2 (RyR2) or its hyperactivation by phosphorylation by serine threonine kinases has been implicated as a central mechanism of AF pathogenesis. Given the role of protein kinase C (PKC) isoforms in cardiac function we investigated role of PKC in AF using a rat model. RESULTS: PMA induced global increase in protein synthesis in cardiac fibroblasts isolated from AF rats, but not healthy controls, and the increase was inhibited by PKC inhibition. PMA mediated activation of both PKC and ERK and either inhibition of PKC by Go6983 or ERK by the MEK inhibitor Trametinib attenuated both P-ERK and P-PKC in both cardiac fibroblasts isolated from AF rats or from healthy rats but transduced with PKC-delta. The PKC and ERK mediated induction of global protein synthesis was found to be mediated by increased phosphorylation of the ribosomal protein S6. CONCLUSION: Our findings provide a foundation for future testing of PKC and MEK inhibitors to treat AF in pre-clinical models. It also needs to be determined if PKC and MAPK pathway activation is functioning via RyR2 or some yet undefined substrates.

Bacterial community shaped by heavy metals and contributing to health risks in cornfields.

Scientists are increasingly aware that heavy metal contamination in soils, especially in farmland ecosystems, can negatively affect human health and alter the bacterial community that plays a critical role in plant growth and heavy metal accumulation. The goal of the present paper was to uncover how various heavy metals and non-metallic elements affect human health and bacterial diversity in cornfields and to explore the contribution of soil bacteria to heavy metal accumulation in crops. Soil samples were collected from five counties in Shandong Province, China, where abnormally high levels of heavy metals and metalloids were caused by mining and heavy industry. We calculated a hazard quotient (HQ) to evaluate the health risk these heavy metals cause and analyzed the soil bacterial community using 16S rRNA gene sequencing. The HQ results showed that As posed the greatest threat to human health followed by Pb although concentrations of all metals did not reach the health risk threshold. Meanwhile, principal component analysis (PCA) and redundancy analysis (RDA) revealed soil bacterial richness was significantly influenced by As, Ni, and Cr as well as pH and phosphorus, but not by the species diversity of aboveground weeds. The most abundant bacteria in our study region were heavy metal tolerant groups, specifically Actinobacteria and Proteobacteria. Moreover, correlation analysis suggested that Actinobacteria might reduce the phytoaccumulation of Cr, Cu, Zn, and Hg in corn, while Proteobacteria might weaken phytoaccumulation of Pb, Ni, As, and Cd. Our results verified that heavy metals play an important role in shaping the soil bacterial community. Using native bacteria in farmland provides a potential biological strategy for reducing the health risk posed by heavy metals related to food consumption.

Clinical comparison of the efficacy of three different bowel preparation methods on the infectious complications following transrectal ultrasonography-guided prostate biopsy in nursing practice.

AIMS AND OBJECTIVES: To assess the effects of three different bowel preparation methods on the incidence of infectious complications in patients who underwent transrectal ultrasonography-guided prostate biopsy. BACKGROUND: The standard bowel preparation protocol for prostate biopsy has not been established. DESIGN: A retrospective study in a single centre. METHODS: From January 2013-December 2015, the clinical records of 1,130 patients who underwent prostate biopsy were, respectively, reviewed. All the patients received metronidazole prophylaxis before biopsy. The patients were divided into three groups according to the bowel preparation methods: patients in Group A (n = 402) received only soapy enema; patients in Group B (n = 413) received polyethylene glycol; while patients in Group C (n = 315) received polyethylene glycol plus povidone-iodine enema. Infectious complications were classified as fever (>37.5°C), urinary tract infection and sepsis. The postoperative adverse events were also observed. RESULTS: The overall postbiopsy infectious complications were observed in 48 (4.25%) patients of all the cases, including 23 (5.72%) cases in Group A, 20 (4.84%) cases in Group B and five patients (1.59%) in Group C. There was significant difference among the groups (p = .018). In detail, these infectious complications included 22 (1.95%) cases of fever and 26 (2.30%) cases of urinary tract infection. No sepsis was observed among the total patients. The incidence of adverse events was 14.43% (58/402) occurred in Group A, 25.91% (107/413) in Group B and 26.67% (84/315) in Group C. The difference was statistically significant. CONCLUSIONS: Our study confirmed that combined preparation regimens of polyethylene glycol with povidone-iodine enema could significantly reduce the postbiopsy infection rate. Conventional soapy enema is associated with less adverse events. RELEVANCE TO CLINICAL PRACTICE: Findings of this study provide useful evidence-based information for healthcare professionals. The application of combined preparation regimens of polyethylene glycol with povidone-iodine enema resulted in better improvement in the prevention of postbiopsy infection.

Highly fabrication tolerant InP based polarization beam splitter based on p-i-n structure.

In this work, a novel highly fabrication tolerant polarization beam splitter (PBS) is presented on an InP platform. To achieve the splitting, we combine the Pockels effect and the plasma dispersion effect in a symmetric 1x2 Mach-Zehnder interferometer (MZI). One p-i-n phase shifter of the MZI is driven in forward bias to exploit the plasma dispersion effect and modify the phase of both the TE and TM mode. The other arm of the MZI is driven in reverse bias to exploit the Pockels effect which affects only the TE mode. By adjusting the voltages of the two phase shifters, a different interference condition can be set for the TE and the TM modes thereby splitting them at the output of the MZI. By adjusting the voltages, the very tight fabrication tolerances known for fully passive PBS are eased. The experimental results show that an extinction ratio better than 15 dB and an on-chip loss of 3.5 dB over the full C-band (1530-1565nm) are achieved.

Roles of NAD in Protection of Axon against Degeneration via SIRT1 Pathways.

Axonal degeneration is a common pathological change of neurogenical disease which often arises before the neuron death. But it had not found any effective method to protect axon from degeneration. In this study we intended to confirm the protective effect of nicotinamide adenine dinucleotide (NAD), investigate the optimal administration dosage and time of NAD, and identify the relationship between silence signal regulating factor 1 (SIRT1) and axonal degeneration. An axonal degeneration model was established using dorsal root ganglion (DRG) neurons injured by vincristine to observe the protective effects of NAD to the injured axons. In addition, the potential contribution of the SIRT1 in axonal degeneration was also investigated. Through the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, immunochemistry staining, axons counting and length measuring, transmission electron microscope (TEM) observation, we demonstrated that NAD played an important role in preventing axonal degeneration. Further study revealed that the expression of SIRT1 and phosphorylated Akt1 (p-Akt1) was up-regulated when NAD was added into the culturing medium. Taking together, our results demonstrated that NAD might delay the axonal degeneration through SIRT1/Akt1 pathways.

[Influence of exogenous nitric oxide on chondrogenic differentiation of adipose derived stem cells].

OBJECTIVE: To determine the effects of exogenous nitric oxide (NO) donor sodium nitroprusside (SNP) on the proliferation and expression of related-gene of adipose-derived stem cells(ADSCs) and its role in chondrogenic differentiation of ADSCs. METHOD: Rat ADSCs were harvested and cultured, and then induced to osteogenic and adipogenic differentiations, detected with Alizarin red stained and Oil red O stain, respectively. The change of NO during chondrogenic differentiation of ADSCs was tested by NO detection kit. Cell counting kit-8 (CCK8) was used to detect the proliferation of ADSCs under different concentrations of SNP (0.25 mmol/L, 1.00 mmol/L, 4.00 mmol/L). Gene expression level of transformation growth factor (TGF-beta1) and specific gene of chondrogenic differentiation-signaling protein Smad3 and Collage II alPHA (Col-II alpha1), were detected by Real time- PCR (RT-PCR) method. RESULTS: Positive alizarin red staining and Oil red O staining were found after osteogenic and adipogenic induction of cultured ADSCs. Higher concentrations of NO were found in the supernatant of the experimental group with ADSCs chondrogenic differentiations compared with the controls (P<0.05). Low concentrations (0. 25 mmol/L, 1.00 mmol/L) of SNP showed no significant effects on cell proliferations (P>0.05), whereas high concentration (4. 00 mmol/L) of SNP inhibited cell proliferation (P<0.05). RT-PCR revealed that SNP inhibited the gene expression of TGF-beta1 mRNA and chondrogenic differentiation of specific gene Smad3 mRNA, Col-II alpha1 mRNA. CONCLUSION: SNP can inhibit chondrogenic differentiations by suppressing the production of TGF-beta1 and inhibiting downstream of TGF-beta1 signaling pathways, thereby inhibiting ADSCs differentiation into chondrocytes.

Widely tunable six-section semiconductor laser based on etched slots.

A six section widely tunable laser based on slots etched into the waveguide is presented. This laser is re-growth free which makes it suitable for photonics integration. To improve the laser performance, the front and the back facets are anti- reflection (AR) coated and the laser is integrated with a semiconductor optical amplifier. A tuning range of 55nm covering 12 supermodes with side mode suppression ratio (SMSR) >30dB is reported for the fabricated device using the Vernier tuning effect. This laser platform requires very simple fabrication compared with more complex superstructure gratings.

Efficacy of catheter ablation of atrial fibrillation in patients with obstructive sleep apnoea with and without continuous positive airway pressure treatment: a meta-analysis of observational studies.

AIMS: An association between obstructive sleep apnoea (OSA) and atrial fibrillation (AF) has been established. However, studies on the role of OSA in AF recurrence after catheter ablation have yielded conflicting results, and the effect of OSA treatment by continuous positive airway pressure (CPAP) on the success rate of AF catheter ablation is indeterminate. The aim of this meta-analysis was to investigate the rate of AF recurrence after catheter ablation in patients with AF with or without OSA and to evaluate the relationship between CPAP therapy and AF recurrence. METHODS AND RESULTS: We performed an online search and identified five studies involving 3743 patients with AF. Patients with OSA had a 31% greater risk of AF recurrence after catheter ablation than did patients without OSA [relative ratio (RR) = 1.31, P = 0.00], and this risk increased by 57% in patients with OSA not undergoing CPAP therapy (RR = 1.57, P = 0.00). However, CPAP users had a risk of AF recurrence similar to that of patients without OSA (RR = 1.25, P = 0.37), and this similarity was maintained even after the removal of study heterogeneity (RR = 0.99, P = 0.39). CONCLUSION: Obstructive sleep apnoea was associated with AF recurrence after catheter ablation. The efficacy of catheter ablation for AF was similar between patients without OSA and patients with OSA undergoing CPAP treatment.

[Construction of beta-catenin miRNA-expressing vectors and test of silencing effect in adipose-derived stem cells from Sprague-Dawley rats].

UNLABELLED: OBEJECTIVE: To construct miRNA-expressing plasmid vector for interfering the expression of beta-catenin in adipose-derived stem cells from Sprague-Dawley rats. METHODS: The double strands oligonucleotides of miR-expressing cassette were ligated into plasmid pSWH to generate pSWH-miR. Then the PCR product of enhanced green fluorescence protein (EGFP) open reading frame (ORF) fragment was inserted into BamH I and Xbo I digested pSWH-miR to generate pSWH-EGFP-miR. The adipose-derived stemcells from rats (rADSCs) were transfected with pSWH-EGFP-miR respectively. The expression of beta-catenin was determined by Western blot at 72 h post-transfection. RESULTS: Five miRNA-expressing plasmid vectors were constructed (miR-780, miR-796, miR-1467, miR-1948, miR-1960). miR-780 and miR-796 had the best silencing effect on the expression of beta-catenin (P < 0.05), less did the miR-1960 (P < 0.05), but not the miR-1467 and the miR-1948 (P < 0.05). CONCLUSION: miR-780 and miR-796 could interference the beta-catenin in ADSCs with high efficiency.

Nine-channel wavelength tunable single mode laser array based on slots.

A 9-channel wavelength tunable single-mode laser array based on slots is presented. The fabricated laser array demonstrated a threshold current in a range of 19~21 mA with the SOA unbiased at 20°C under continuous wave condition. Stable single mode performances have been observed with side-mode suppression-ratio (SMSR) > 50 dB. The output power higher than 37 mW was obtained at the SOA injected current of 70 mA for all the 9 channels within the laser array. A wavelength quasi-continuous tuning range of about 27 nm has been achieved for the laser array with the temperature variations from 10°C to 45°C. This array platform is of a single growth and monolithically integrable. It can be easily fabricated by standard photolithography. In addition, it potentially removes the yield problem due to the uncertainty of the facet cleaving.

[Influence of fetal bovine serum protein concentration in adipose tissue extract on adipogenic differentiation of adipose derived stem cells].

OBJECTIVE: To observe whether fetal bovine serum (FBS) will affect the adipogenic ability of adipose derived stem cells (ADSCs) induced by adipose tissue extract (ATE), and to explore the effects of different FBS protein concentrations in ATE on adipogenic ability, cell proliferation and migration of ADSCs. METHODS: Rat ADSCs were cultured, passaged, and then subjected to osteogenic and neural induction. The adipose explants were cultured in culture medium with or without FBS, then ATE was collected to induce passage four (P4)-ADSCs, which were subsequently detected with oil red staining on the 7th day and the adipogenic ratio was calculated. Different concentrations of ATE without FBS (100 microg/mL, 250 microg/mL and 500 microg/mL) were used to induce P4-ADSCs before the adipogenic events, and the adipogenic ratio of each concentration group was observed. The effect of different protein concentrations on ADSCs proliferation and migration was also observed. RESULTS: Alizarin red staining and NF immunofluorescence staining were positive after the osteogenic and neural induction of cultured ADSCs. Either ATE with or without FBS was able to induce adipogenic differentiation of ADSCs on the 3rd day and there was no significant differences of adipogenic differentiation between ATE with FBS and without FBS on the 7th day. The adipogenic ratio of 500 microg/mL group was higher than that of 100 pg/mL group and 250 microg/mL group (P < 0.05). After two days of induction, all the three different protein concentrations could inhibit cell proliferation, and different protein concentrations in ATE had no effect on the migration of ADSCs. CONCLUSION: ATE obtained from culture medium without FBS has no effect on adipogenic capacity of ADSCs in a short period of time. The adipogenic ratio of ADSCs is associated with protein concentration in ATE.

[Research on the effect of extract of dentin matrix on the differentiation of dental pulp cells].

OBJECTIVE: To investigate the effects of human treated dentin matrix (hTDM) extracellular matrix molecules on odontogenetic and neural differentiation of human dental pulp cells (hDPCs) with an aim to find an effective method to collect extracellular matrix molecules to contribute to reparation dental-pulp complex with dentin defects. METHODS: hDPCs were obtained and biological characteristics such as source of cells and multi-differentiation potentials were assessed using immunofluorescence and flow cytometry. Fabrication of hTDM extracts and hDPCs was induced with it for 1 week. The odontogenetic differentiation associated genes were tested by qRT-PCR. Results qRT-PCR results showed that cells were higher expression of odontogenetic differentiation associated genes ALP, OPN, OCN, BSP, DMP-1, DSP, beta-III tubulin. CONCLUSION: The method of extracting extracellular matrix molecules from dentin matrix was effective. The extract liquid provides a suitable microenvironment for odontogenetic and neural differentiation of hDPCs and contributes to reparation dental-pulp complex.

[Increased survival of free fat grafts with adipose-derived stem cells and platelet-rich plasma in nude mice].

OBJECTIVE: To investigate the impact of combined adipose-derived stem cells (ASCs) and platelet-rich plasma (PRP) on the survival of transplanted fat. METHODS: The ASCs were isolated and cultured from fat tissues by enzyme digestion; and the PRP was prepared by two-step ultracentrifugation. The grafts of fat granules were divided into test groups (ASCs + PRP + fat granules, PRP + fat granules, ASCs + fat granules) and control groups (PBS + fat granules). The grafts were injected into the left and right dorsal subcutaneous areas of nude mice. General observations, volume measurements and microscope examinations were conducted 10 d, 30 d, 60 d and 90 d after transplantation. RESULTS: The grafts of the mice in the ASCs + PRP group showed soft structure, with light yellow color and closer to normal adipose tissue compared with those in other groups. Greater survival volumes (P < 0.05) and better histology were also observed in the grafts of the mice in the ASCs + PRP group. CONCLUSION: The fat grafts consisting of PRP and ASCs constitute an ideal transplant strategy, which could provide a valuable and needed tool in plastic and reconstructive surgery.

[The research on the induction of secretome by adipose tissue for adipose-derived stem cells].

OBJECTIVE: Study the role for adipose tissue-derived stem cells (ADSCs) of secretome by adipose tissue and hoped that makes some contributions for the fat regeneration. METHODS: Direct adherent culture methods and the flow cytometry (FCM) were used to isolate and identify ADSCs. Collected the medium that had contained secreted proteins as the conditional medium (CM) and was used to induce ADSCs, chemical medium group as the positive control and normal medium group as the negative control. The formation of lipid drops was observed through the cell morphology, and the reliability was verified through Real-time PCR of the mRNA level in vitro. To test the effect of CM on ADSCs in vivo, the absorbable gelatin sponge was used as a scaffold for ADSCs. RESULTS: FCM ensured that the cultured cells were ADSCs. Significant increased lipid drops and related mRNA levels were observed in induced ADSCs cultured for 4 days, which indicated that the CM could promote the ADSCs differentiate into adipocytes after cultured for 4 days in vitro. The secreted proteins could promote ADSCS differentiate into vascularization tissues in vivo. CONCLUSION: The secreted proteome may contain some growth factors that can promote ADSCs to differentiate into adipocytes and vascularization, which may give new directions for the growth factors that could be applied in the repair of soft tissue.

Clinical Features Associated with 'Normal Range' Fibrin D-Dimer Levels in Atrial Fibrillation Patients with Left Atrial Thrombus.

BACKGROUND: Left atrial thrombus (LAT) often complicates with atrial fibrillation (AF). The evidence whether fibrin D-dimer levels could be used as a predictive biomarker for LAT is contradictory. This study firstly investigated the relationship between 'normal range' D-dimer and prevalent LAT. Second, we explored factors contributing to normal D-dimer levels in the presence of LAT. METHODS: We studied 244 AF patients with LAT (mean age: 59.9 years, SD:11.7; 53.3% female): of these, 103 (42.2%) had normal D-dimer, 25 (10.2%) had atrial thrombus exclusion score (ATE score) of 0 19 (16.7%) males had CHA2DS2-VASc score of 0, 21(16.2%) females had CHA2DS2-VASc score of 1 and 16 had overlapped ATE score of 0 and CHA2DS2-VASc score of 0 (N = 8 if male) or CHA2DS2-VASc score of 1(N = 8 if female). Using multivariate binary analysis, larger left atrial diameter (LAD; adjusted OR: 1.06, 1.03-1.10, p = 0.001) were associated with increased D-dimer. Patients with high body mass index (BMI), hypertension history and previous anticoagulation were more likely to show normal range D-dimer levels in the presence of LAT. CONCLUSIONS: A high prevalence (42.2%) of 'normal range' D-dimer levels was found in AF patients with LAT, especially in those with hypertension, high BMI and prior anticoagulation. D-dimer levels of those patients with larger LAD were more likely to be increased.

Prevalence, incidence and mortality of hypertrophic cardiomyopathy based on a population cohort of 21.9 million in China.

There are limited studies on the prevalence and incidence of clinically diagnosed hypertrophic myocardiopathy (HCM) and its mortality in the Chinese population, and the projected population burden of HCM over the next decades. We collected data on HCM and its mortality from the Beijing Municipal Health Commission Information Center (BMHCIC) database and estimated the prevalence and incidence based on the whole Beijing population. Calculation of population trends was performed using annual percentage change (APC) and average annual percentage change (AAPC). Finally, future HCM incidence was built by modelling projection of HCM to the next decades using Poisson regression analysis and Gray Model 1,1(GM [1,1]). The prevalence of HCM was 0.0069% (95%CI, 0.0065-0.0072%; N = 1343) in 2010, rising to 0.076% (95% CI, 0.074-0.077%; N = 16,616) in 2019, and the incidence of HCM was 6.85 per 100 000 person-year in 2010, rising to 11.76 per 100 000 person-year in 2019. Males had higher prevalence and incidence of HCM than females. The APPC for the rising incidence of HCM was 5.8% and the expected numbers will double increase in 2029 by assuming the same increase trend as the last decades. HCM had increased annual incidence of HF (APPC: 8.4, 4.4-12.6, p < 0.05), and relatively stable annual incidence of mortality (APPC: 1.2%, - 2.3% to 4.8%, p > 0.05) during the studied period. Males had lower mortality (2.70% vs. 4.20%, p < 0.001) than females. The calculated HCM prevalence was much lower compared to prior screening studies from 2004, although the predicted HCM incidence would double over the next decades. HCM was associated with a stable risk of mortality during the studied period.
