MEFIB (the combination of magnetic resonance elastography [MRE]≥3.3kPa and fibrosis-4 (FIB-4)≥1.6) is useful for detecting patients with significant fibrosis (fibrosis stage ≥2) having nonalcoholic fatty liver disease (NAFLD). However, age-dependent thresholds of FIB-4 have been proposed, and it remains unclear whether MEFIB could be applied with the same FIB-4 threshold in a different cohort. Therefore, in this study, we examined the best threshold of FIB-4 and validated the utility of MEFIB.

This study included 105 biopsy-proven NAFLD patients with contemporaneous MRE assessment. The primary outcome was a diagnostic accuracy for significant fibrosis.

The median (interquartile range) age was 65 (58-72)years, and significant fibrosis was 76.2% (80/105). FIB-4 of 2.1 was defined as the best threshold for significant fibrosis in the cohort. The area under the receiver operating characteristics curves (AUROCs) of the combination of MRE and FIB-4 (MRE≥3.3kPa+FIB-4≥1.6 0.80, MRE≥3.3kPa+FIB-4≥2.1 0.84) were higher than those of each index alone (MRE≥3.3kPa 0.76, FIB-4≥1.6 0.72, and FIB-4≥2.1 0.77), but AUROCs of MRE≥3.3kPa+FIB-4≥1.6 and MRE≥3.3kPa+FIB-4≥2.1 were equivalent (P=0.3).

MEFIB is useful for detecting patients with significant fibrosis and could be utilized in a different cohort without changing the threshold of FIB-4, and it may then be used as a two-step screening strategy.

The reactivities of these radical intermediates were captured by nickel catalysis with organobromides including aryl, heteroaryl, alkenyl, and alkyl bromides, enabling six diverse C-C bond formations. Classic named reactions including Negishi, Suzuki, Heck, and Sonogashira reactions were readily achieved in a net-reductive fashion under mild conditions. More importantly, the cross coupling was viable with either organic bromide or iodide as limiting reactant based on the availability of substrates, which is beneficial to the late-stage functionalization of complex molecules. The scalability of this method in batch and flow was investigated, further demonstrating its applicability.

The aims of this study were to assess the prognosis of patients after a single haemorrhage from the cavernoma, and also in the case of rehaemorrhage, and to determine the indications for surgical treatment of brainstem cavernomas.

The study included a group of 35 patients with brainstem cavernomas, 23 women and 12 men aged 27 to 57 years (mean age 38.4). Up to 2005, MRI perfusion-weighted imaging/diffusion-weighted imaging had been carried out in 13 surgically treated patients. From 2005 onwards, the other 22 patients also underwent MRI diffusion tensor imaging and diffusion tensor tractography (DTI/DTT). DTI/DTT assessed the course of long fibre tracts. The course of the corticospinal tract, medial lemniscus and transverse pontine tracts was entered into the neuronavigation system. The surgical approach and the safe entry zone were determined based on the DTI/DTT.

Our study showed that rehaemorrhage from a cavernoma depends on its size and volume. However, it is not related to its location. Based on thperation is required.

Patients with brainstem cavernomas should undergo surgical treatment after their first haemorrhage, especially in the case of a large cavernoma. DTI/DTT should be used to determine the trajectory to the cavernoma, particularly to the deep cavernoma, and to determine the safe entry zone. Total resection of the cavernoma should be performed even where this means that reoperation is required.

Hyaluronan (HA) oligosaccharides are involved in several biological processes, primarily collagen remodeling and wound healing. Collagen remodeling is retarded in aging skin and causes wrinkles. The aim of this study was to evaluate the effect of 2-kDa HA oligosaccharides (HA2k) on wrinkles by permeation through the stratum corneum and promotion of collagen remodeling.

A 3D skin model and excised human skin were used to evaluate the permeation of fluorescein-labeled HA2k. The effect of HA2k on collagen metabolism was evaluated by measuring the protein level of type 1 pro-collagen (COL1A1) and matrix metalloproteinase-1 (MMP-1) in the 3D skin model. 0.1% HA2k solution and vehicle control was applied to the human forearm for 8 weeks to evaluate dermal collagen density. To evaluate the effect of HA2k on depth of facial wrinkles, a randomized controlled trial was conducted with 0.1% HA2k lotion and vehicle lotion for 8 weeks.

HA2k was confirmed to permeate through the stratum corneum by fluorescent microscopy. Both COL1A1 and MMP-1 were upregulated by HA2k application in a 3D skin model culture. The collagen density was higher for the HA2k-treated forearm than for the vehicle control-treated forearm after 4 weeks. The maximum wrinkle depths in the nasolabial fold and crow's feet area were significantly shallower in the HA2k lotion group than in the control group.

HA2k permeated the stratum corneum, activated collagen synthesis and degradation simultaneously, and ameliorated wrinkles.

Reactive reporting may occur in response to dietary recording but little is known about how image-based methods influence this process. Using a 4-day image-based mobile food record (mFRTM), this study aimed to identify demographic and psychosocial correlates of measurement error and reactivity bias, among adults with BMI 25-40kg/m2. Participants (n=155, aged 18-65y) completed psychosocial questionnaires, and kept a 4-day mFRTM. Energy expenditure (EE) was estimated using ≥4 days of hip-worn accelerometer data, and energy intake (EI) was measured using mFRTM. Energy intake energy expenditure ratios were calculated, and participants in the highest tertile were considered to have Plausible Intakes. Negative changes in EI according to regression slopes indicated Reactive Reporting. Mean EI was 72% (SD=21) of estimated EE. Among participants with Plausible Intakes, mean EI was 96% (SD=13) of estimated EE. Higher BMI (OR 0.81, 95%CI 0.72-0.92) and greater need for social approval (OR 0.31, 95% CI 0.10-0.96), were associated with lower likelihood of Plausible Intakes. Estimated EI decreased by 3% per day of recording (IQR -14%,6%) among all participants. The EI of Reactive Reporters (n=52) decreased by 17%/day (IQR -23%,-13%). A history of weight loss (>10kg) (OR 3.4, 95% CI 1.5-7.8), and higher percentage of daily energy from protein (OR 1.1, 95%CI 1.0-1.2) were associated with greater odds of Reactive Reporting. Identification of reactivity to measurement, as well as Plausible Intakes, is recommended in community-dwelling studies to highlight and address sources of bias.The internet offers exciting opportunities for quick, cost-efficient, and widespread recruitment and data collection without face-to-face contact. Previous research has demonstrated success in reaching population subgroups not typically included in traditional recruitment methods, yet challenges in data quality protection remain paramount. This article describes using Amazon Mechanical Turk, Facebook groups, and email distribution lists to recruit older adults who live alone for a quantitative study using a cross-sectional online survey. Fraudulent survey takers became a major concern in this study, and a protocol was developed to identify and exclude suspicious data. Of 738 recorded participants, 117 responses were retained in the final sample. The majority of sham responses were collected from Facebook with the fewest number of issues identified in responses collected via targeted emailing. Implications for survey design, data analysis, and future research are discussed.Technology-enabled approaches to conducting 24-hour dietary recalls (24HR) may reduce dietary assessment bottlenecks in low-resource settings. However, few studies have assessed their performance relative to conventional pen-and-paper interview (PAPI) approaches and none have validated performance against a benchmark (e.g. weighed food record [WFR]) in a low and middle-income country (LMIC). This study assessed relative accuracy and cost-effectiveness of INDDEX24, a technology-enabled approach to conducting 24HR, compared to a PAPI approach and against an observer WFR. Women aged 18-49 years from northern Viet Nam (n=234) were randomly assigned to be interviewed using INDDEX24 or PAPI 24HR following a WFR. The two one-sided T-test approach assessed the equivalence of each recall modality to the benchmark. Difference-in-differences analysis compared the recall-benchmark results across modalities. Cost per percentage point of accuracy for INDDEX24 and PAPI was derived from accuracy results and the cost to conduct the 24HRs. The PAPI and INDDEX24 24HRs were statistically equivalent to the WFR for all nutrients except vitamin A. INDDEX24 diverged significantly less than PAPI from the WFR for iron (0.9 v. -1.3 mg) and PAPI diverged less for protein (-3.7 v. 7.9 grams). At the individual level, 26% of PAPI and 32% of INDDEX24 respondents had energy intakes within +/- 10% of the WFR. INDDEX24 cost $111,004 and the PAPI $120,483 (USD 2019), making INDDEX24 more cost-effective across most indicators. INDDEX24 was an accurate and cost-effective method for assessing dietary intake in the study context and represents a preferred alternative to PAPI 24HRs in Viet Nam and other LMICs.

Airway management is a controversial topic in modern Emergency Medical Services (EMS) systems. Among many concerns regarding endotracheal intubation (ETI), unrecognized esophageal intubation and observations of unfavorable neurologic outcomes in some studies raise the question of whether alternative airway techniques should be first-line in EMS airway management protocols. Supraglottic airway devices (SADs) are simpler to use, provide reliable oxygenation and ventilation, and may thus be an alternative first-line airway device for paramedics. In 2019, Alachua County Fire Rescue (ACFR; Alachua, Florida USA) introduced a novel protocol for advanced airway management emphasizing first-line use of a second-generation SAD (i-gel) for patients requiring medication-facilitated airway management (referred to as "rapid sequence airway" [RSA] protocol).

This was a one-year quality assurance review of care provided under the RSA protocol looking at compliance and first-pass success rate of first-line SAD use.

Recoired emergent exchange upon hospital arrival.

First-line use of a SAD was associated with a high first-pass attempt success rate in a real-life cohort of prehospital advanced airway encounters. No SAD required emergent exchange upon hospital arrival.
