in single-rod constructs. The use of dual-rod constructs allows for better curve control, greater T1-S1 length increase and a lower complication rate.

Better understanding is needed about the debris-and-irrigant-extrusion potential of the instruments used for root canal preparation procedures, manufactured of different heat-treated alloys.

The aim of the study was to evaluate the single-file nickel-titanium (NiTi) rotary system OneShape® and compare it with 2 different heat-treated instrumentation systems produced by the same manufacturer - a single-file C-wire system (One Curve®) and a multi-file T-wire system (2Shape®) - in terms of debris and irrigant extrusion.

The mesiobuccal root canals of 51 extracted mandibular molar teeth were selected for the study. The roots were applied to the test apparatus prepared with the Myers and Montgomery method. The roots were divided into 3 groups according to the instrumentation system OneShape; One Curve; and 2Shape. The root canals were prepared according to the manufacturer's instructions. The analysis of variance (ANOVA) and the post hoc Tukey tests were used to evaluate the significance of the amount of theat produced by the OneShape system and lower than in the case of the 2Shape system.The purposes of this review were to appraise the current evidence on the management of orthodontically induced white spot lesions (OIWSLs) and to choose the best evidence from among conflicting systematic reviews. The published literature was searched from inception through November 2019 in 5 databases. Only systematic reviews and/or meta-analyses were eligible for inclusion. Methodological quality was assessed using A Measurement Tool to Assess Systematic Reviews-2 (AMSTAR-2). The Jadad decision algorithm was applied to choose the best available evidence from among discordant reviews. Thirteen publications were included. The interventions reported in the management of OIWSLs were topical fluorides, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-containing products, fluoridecontaining bonding materials, laser therapy, resin infiltration, and micro-abrasion. The methodological quality of the reviews ranged between moderate and critically low according to the AMSTAR-2 tool. Based on the Jadad decision algorithm criteria, topical fluorides yielded a 25-30% prevention of OIWSLs; however, their effect on reversing OIWSLs was unclear. The CPP-ACP products were effective in both preventing and reversing OIWSLs. compound 3k PKM inhibitor No differences were noted between fluoride-releasing adhesives and conventional adhesives. Laser irradiation was effective in preventing OIWSLs, with some concerns about the argon laser at a certain setting. Finally, there is a lack of reliable evidence supporting the efficacy of resin infiltration or micro-abrasion due to the limited number of available studies. Based on the currently available information, topical fluorides and laser irradiation are effective in preventing OIWSLs. link2 The CPP-ACP products are effective in preventing and reversing OIWSLs. Fluoride-releasing adhesives have no effect on OIWSL prevention.Optimal complementary feeding practices including consumption of multiple micronutrient powders (MNP) are recommended to improve micronutrient intake by infants and young children (IYC) 6-23 months. Formative research was used to design the behaviour change strategy to improve IYC micronutrient intake for the multicountry ENRICH project in rural impoverished areas of Tanzania, Kenya, Bangladesh and Pakistan. Employing a qualitative approach with multiple methods and guided by a social ecological framework, the study was conducted in several phases data collection in the community, household and health facilities, initial analysis and household trials (HHT). Results found limited use of animal source foods (ASF) for feeding IYC and MNP largely unavailable. Although cost constrained access to ASF, potential more affordable context-specific ASF options were identified in each setting. Caregivers associated ASF with many positive attributes for IYC, but barriers to feeding them included lack of caregiver time and knowledge of specific preparation techniques, and limited advice from health workers. Feeding practices were identified that used time-efficient, specific preparations for eggs and other ASF, and demonstrated good initial acceptability and feasibility during HHT. Testing MNP in HHT found good initial feasibility and acceptability and provided an understanding of the facilitators and constraints for preparing, feeding and promoting MNP. In conclusion, formative research led to the design of context-specific ASF and MNP complementary feeding promotion strategies to improve IYC consumption of micronutrients by identifying the practices, benefits, motivations and alternative actions to overcome the barriers in each setting.

Attention deficit hyperactivity disorder (ADHD) and the medications used to treat it are associated with obesity. Stimulants lead to weight loss, while antipsychotics and antidepressants lead to weight gain. Little is known, however, how alpha-2-agonists impact weight, or the independent effect on BMI of these four classes of medications, which are often prescribed concurrently. We aimed to estimate the proximal change in BMI associated with start of medication and to assess whether medication-specific departures in BMI varied by age and sex.

We analysed longitudinal electronic health records from children (4-19 years) with an ADHD diagnosis seen at one healthcare system (2011-2018). Their BMI z-scores were fit as a cubic function of age via a mixed model, separately by sex and adjusting for race/ethnicity. From this model, we estimated annual changes in BMI-z after medication, allowing changes to vary by age and sex.

Among the 22 714 children with ADHD (mean initial age = 10.0), 4335 (19.1%) were never prescribed ADHD medication. The others (80.9%) experienced departures in BMI-z after start of all four medication classes, which varied across age and sex (interaction P-values < .01). All medications had larger impacts at younger ages. As expected, decreased BMI-z was observed with stimulants, while antidepressants and antipsychotics led to BMI-z increases; alpha-agonists also were associated with BMI-z increases.

This longitudinal study revealed that ADHD medications are independently associated with proximal changes in BMI-z after initiation, significantly varying by sex and age. Future research should study further the interactions of these medications on long-term impacts on obesity.

To evaluate utility of the complex percutaneous coronary intervention (PCI) criteria in real-world practice.

Applicability of procedural complexity criteria for risk stratification has not been adequately evaluated in real-world practice.

Among 13,087 patients undergoing first PCI in the CREDO-Kyoto registry cohort-2, the study population consisted of 7,871 patients after excluding patients with acute myocardial infarction and those without stent implantation. Complex PCI was defined as PCI, which fulfills at least one of the followings three vessels treated, > = 3 stents implanted, > = 3 lesions treated, bifurcation with two stents, >60 mm total stent lengths, and target of chronic total occlusion.

The cumulative incidences of and adjusted risks for the primary ischemic (myocardial infarction/ischemic stroke), and bleeding (GUSTO moderate/severe) endpoints were significantly higher in patients with complex PCI (N = 2,777 [35%]) than in those with noncomplex PCI (N = 5,094 [65%]) (15.4% vs. 10.9%, log-rank p < .001; odds ratio (OR) 1.53, 95% confidence interval (CI) 1.31-1.79, p < .001, and 11.9% vs. 9.9%, log-rank p = .004; OR 1.24, 95% CI 1.05-1.46, p = .01). In the 30-day landmark analysis, the higher risks of patients with complex PCI for ischemic and major bleeding events were only seen within 30 days after PCI (ischemic; within 30 days HR 2.19, 95% CI 1.79-2.69, p < .001; beyond 30 days HR 1.11, 95% CI 0.92-1.34, p = .26, and bleeding; within 30 days HR 1.56, 95% CI 1.13-2.16, p = .007; beyond 30 days HR 1.11, 95% CI 0.94-1.31, p = .22).

Patients with complex PCI as compared with patients with noncomplex PCI had a higher risk for both ischemic and bleeding events mainly within 30 days after PCI.

PAR1KO PDAC cells are preferentially eliminated from growing tumors. Thrombin-PAR1 signaling in PDAC tumor cells drives an immunosuppressive gene signature. Csf2 and Ptgs2 are thrombin-PAR1 downstream immune suppressor genes in PDAC tumor cells. ABSTRACT Background Pancreatic ductal adenocarcinoma (PDAC) is characterized by a prothrombotic state and a lack of host antitumor immune responsiveness. Linking these two key features, we previously demonstrated that tumor-derived coagulation activity promotes immune evasion. Specifically, thrombin-protease-activated receptor-1 (PAR1) signaling in mouse PDAC cells drives tumor growth by evading cytotoxic CD8a+ cells. Methods Syngeneic mixed cell tumor growth, transcriptional analyses, and functional tests of immunosuppressive response genes were used to identify cellular and molecular immune evasion mechanisms mediated by thrombin-PAR-1 signaling in mouse PDAC tunsight into the mechanisms of a previously unrecognized pathway coupling coagulation to PDAC immune evasion by identifying PAR1-dependent changes in the tumor microenvironment, a PAR1-driven immunosuppressive gene signature, and Csf2 and Ptgs2 as critical PAR1 downstream targets.The COVID-19 outbreak has shut down universities and prompted the teaching faculty to move to online resources. link3 In view of upcoming of new Medical Council of India (MCI) curriculum and outbreak of COVID-19 pandemic, keeping pace with medical education became a challenge. To keep on par with learning activities of undergraduate students during this period, the teaching faculty adopted the use of online resources. E-learning tools were utilized to engage first-year undergraduate students and satisfy majority of aspects of Competency-Based Undergraduate Medical Curriculum/Education (CBMC/E) in Biochemistry.

Case report notions of unexpected memory retrieval in patients with severe dementia near to death are starting to alter the central "irreversible" paradigm of dementia and locate dementia as a problem of memory retrieval, not consolidation. We suggest that the most likely central tenet of this paradoxical memory retrieval is the fluctuation of neuromodulators projecting from the brain stem to the medial prefrontal cortex and the hippocampus. The neuromodulation-centric explanation of this phenomenon aims to open the "irreversible" paradigm of dementia up for discussion and suggest a plausible treatment strategy by questioning how the devastating process of death fluctuates memory performance in severe dementia.

Supporting demented patients, who are mostly unresponsive, without making demands or asking a question and regarding them as valuable human beings unexpectedly improve their memory performance around the time of death.

Around the time of death, neurological signs (hyper-arousal and -attention) of demented people point out that neurotransmitter discharges are dramatically changed.
