fetal, placental, parental, newborn, and postnatal variables were studied. Results a total of 358 SGAs were included from a total of 5,585 live newborns. At 6 and 48 months of life, 93.6 % and 96.4 % of SGAs achieved CUG, respectively. By subgroups, symmetric SGAs performed worse than asymmetric SGAs with CUG in 84 % and 92 % at 6 and 48 months of life, respectively. The same occurred in the subgroup of preterm SGAs with respect to term SGAs, with worse CUGs of 88.2 % and 91.2 % at 6 and 48 months of life, respectively. Prematurity, symmetrical SGA, intrauterine growth retardation (IUGR), preeclampsia, previous child SGA, perinatal morbidity, and comorbidity during follow-up were associated with absence of CUG. Conclusions the majority of SGAs had CUG in the first months of life. The worst outcomes were for preterm and symmetric SGAs.Introduction Biodegradable stents of various designs are reportedly used in pancreato-biliary conditions with promising results. Their major advantage is the avoidance of a repeat endoscopic procedure for stent removal thereby reducing overall cost along with ERCP associated adverse events. To evaluate the feasibility and safety of a new biodegradable stent in patients with pancreato-biliary diseases. Methods Prospective multicenter pilot study. All consecutive patients 18 years-old who underwent biliary or pancreatic stenting using the new biodegradable Archimedes stent were included. There were three biodegradation profiles. Technical and clinical success, feasibility and safety were assessed during a pre-established follow-up schedule. Results Fifty-three patients (mean age 48.54±19.29, 66% male) having biliary (n=29, 54.7%%) or pancreatic (n=24, 45.3%) indications were included. The distribution of stents used according to degradation properties were as follows fast (n=11, 20.8%), medium (n=16, 30.2%) and slow (n=26, 49.1%). The technical and clinical success were 100% and 77.8%. Thirty-five patients were followed for a median of 26 weeks (range 4-56, 66%). There were 9 procedure-related adverse events (17%), all mild, including one uneventful stent-related event (external migration). Conclusion The biodegradable Archimedes stent placement is feasible and safe in pancreato-biliary diseases.

Background it is unknown whether patients with acute respiratory distress syndrome (ARDS) secondary to COVID-19 are at greater risk of developing complications associated with parenteral nutrition (PN). Aim to describe the incidence, risk factors, and clinical impact of complications in patients with ARDS-COVID-19 receiving PN. Methods a prospective cohort study of 87 patients with ARDS-COVID-19 infection. The incidence of complications and odds ratios of risk factors were analysed. Results age ≥ 65 years (OR, 2.52, 95 % CI 1.16 to 5.46), obesity (OR, 3.34, 95 % CI 2.35 to 4.33) and treatment with propofol (OR, 2.45, 95 % CI 1.55 to 3.35) or lopinavir/ritonavir (OR, 4.98, 95 % CI 3.60 to 6.29) were risk factors for hipertriglyceridemia. Obesity (OR, 3.11, 95 % CI 1.10 to 8.75), dyslipidemia (OR, 3.22, 95 % CI 1.23 to 8.40) or treatment with propofol (OR, 5.47, 95 % CI 1.97 to 15.1) were risk factors for intravascular catheter-related infection. No risk factors were described for hiperglycemia. Mortality wasR, 3.34, 95 % CI 2.35 to 4.33) and treatment with propofol (OR, 2.45, 95 % CI 1.55 to 3.35) or lopinavir/ritonavir (OR, 4.98, 95 % CI 3.60 to 6.29) were risk factors for hipertriglyceridemia. Obesity (OR, 3.11, 95 % CI 1.10 to 8.75), dyslipidemia (OR, 3.22, 95 % CI 1.23 to 8.40) or treatment with propofol (OR, 5.47, 95 % CI 1.97 to 15.1) were risk factors for intravascular catheter-related infection. No risk factors were described for hiperglycemia. Mortality was higher in patients with intravascular catheter-related infection (46.7 % vs 10.8 %, p = 0.014). Mortality risk was higher in older patients (OR, 2.74, 95 % CI 1.08 to 6.95) or patients with intravascular catheter-related infection (OR, 3.22, 95 % CI 1.23 to 8.40). Conclusions the incidence of complications associated with PN in patients with COVID-19-related ARDS is frequent. The mortality risk is higher in older patients or those with catheter-related infection.

The COVID-19 pandemic has had a major impact on hepatitis C virus (HCV) diagnosis by hindering the path to elimination, although probably in an uneven manner depending on the risk group and diagnostic strategy.

We recorded the requests of antibodies/RNA by venipuncture at the hospital and primary care centres (centralised), as well as the requests via venipuncture or dried blood spot test at prison and drug treatment centres referred for central processing (integrated decentralised), for one year before and after the onset of the COVID-19 health alarm.

A total of 20,600 tests (51% male, 47.9±15.8 years) were recorded. Among them, 96.5% of the cases came from centralised and 3.5% from decentralised settings, with an active infection rate of 0.2% and 2.3% (p<0.001), respectively. There was a 31.3% decrease in the number of requests during the pandemic compared to the pre-pandemic period, which was more pronounced in decentralised diagnosis than centralised (60 vs. 30%, p<0.001). In addition, there was a 31.5% decline in screening and an 18.2% decrease in the diagnosis of new cases of active infection, showing a statistically significant decrease in decentralised compared to centralised diagnosis.

During the COVID-19 pandemic, a decline in HCV diagnostic effort has been observed, especially in decentralised strategies with a higher prevalence of infection. Our results suggest a diagnostic delay that will prevent Spain from reaching the elimination target in 2023, and therefore the reactivation of strategies particularly targeting the priority groups is urgently required.

The two annulation reactions proceed under mild conditions and bear broad substrate scope and high yield.An elegant and catalytic procedure for the one-step cyanomethylenation of C(sp3)-H bonds adjacent to benzazoles and ketones is described herein using DMF as a C-1 unit and TMSCN as the cyanide source. The copper-mediated reaction between DMF and TMSCN gives a cyanomethylene radical intermediate that reacts with 2-alkylbenzazoles or alkylketones to furnish desired cyanomethylenated compounds under palladium catalysis. Subsequent interconversion of cyanomethylenated products makes the protocol synthetically attractive.A new colorimetric and fluorescent turn-on probe named 2,4-bis(camphor-3-methylene)phenylacrylate (BCP-Cys) was designed for highly sensitive and specific monitoring of cysteine (Cys). The probe BCP-Cys was strategically constructed by employing a new bis-camphor-derived scaffold (BCP-OH) as the fluorophore and an acrylate group as the recognition site and fluorescence quencher. The acrylate group of BCP-Cys could be exclusively cleaved by Cys and release the fluorophore BCP-OH, thereby causing a significantly enhanced red fluorescence and a naked-eye colorimetric change from colorless to yellow. The probe BCP-Cys exhibited promising sensing performances for Cys including large Stokes shift (184 nm), fast response time ( less then 1 min), wide linear range (0-100 nM), and low detection limit (0.0728 μM). Moreover, the probe BCP-Cys could be utilized as a powerful tool for real-time determination of Cys levels within different food samples, such as onion, cabbage, broccoli, garlic, cauliflower, and bamboo sprout. In addition, this probe was also capable of imaging endogenous and exogenous Cys in living cells.Lithium-ion battery (LIB) design is the predominant technology to power portable and mobile electric devices/equipment. Fast charging and self-powering of LIBs are significant but challenging features to be addressed for meeting the fast-paced society and emerging demands. Herein, we report a rational photorechargeable lithium-ion battery (photo-LIB) design using LiV2O5 as a photocathode by directly modifying a commercial LIB without using any additives, which works in both photoassisted fast charging and photo-only charging modes. The photo-LIB attains a high specific capacity of 185 mAh g-1 in as fast as 5 min under illumination, an enhancement of 270% referring to that in dark. Under the photo-only charging mode, the device achieves a highest full-spectrum photo-energy conversion efficiency of 9% so far, demonstrating a highly efficient self-powering mode. We reveal that the improved performance of photo-LIB is due to reversible vanadium intervalence charge transfer and Li+ insertion/deinsertion in LiV2O5 under illumination.Birefringent materials capable of modulating the polarization of light have attracted intensive studies because of their wide utilization in optical communication and the laser industry. Herein, two new lead(II)-based cyanurates, namely, Pb(H2C3N3O3)X (X = OH, F), were synthesized by hydrothermal methods, and the first halogen-containing metal cyanurate Pb(H2C3N3O3)F was successfully obtained by the rational substitution of a homovalent anion. Pb(H2C3N3O3)X (X = OH, F) belong to space group P1̅, and their structures display a neutral [Pb(H2C3N3O3)X] (X = OH, F) layer. The Pb2+ ions in Pb(H2C3N3O3)(OH) are interconnected by hydroxyl groups and oxygen atoms of cyanurate anions into a 1D [PbO(OH)]- chain, whereas the Pb2+ ions in Pb(H2C3N3O3)F are interconnected by F- anions and oxygen atoms of cyanurate anions into a 2D [PbOF]- layer. The π-π interactions between adjacent hydroisocyanurate rings and the hydrogen bonds between neighboring neutral layers provide additional stability to the structures. Luminescent studies show that Pb(H2C3N3O3)(OH) and Pb(H2C3N3O3)F emit yellow-green and blue light, respectively. Theoretical calculations unveiled their birefringences of 0.079 and 0.203@1064 nm and their band gaps of 3.96 and 4.96 eV, respectively, for OH- and F- containing materials. Obviously, the substitution of OH- by F- with the largest electronegativity can simultaneously improve both the birefringence and band gap.In the present study, the impact of galactooligosaccharide (GOS) addition to a plant sterol (PS)-enriched beverage on the hypocholesterolemic effect and on the bioavailability and colonic metabolization of sterols was evaluated. A crossover trial was undertaken in postmenopausal women who intook a PS-enriched (2 g PS/day) or PS-GOS-enriched beverage (2 g PS/day and 4.3 g GOS/day) for 6 weeks. The presence of GOS did not modify the hypocholesterolemic effect of the PS-enriched beverage (total- and low-density lipoprotein-cholesterol reductions) or sterol bioavailability (increments of serum markers of dietary PS intake and of cholesterol synthesis). The consumption of both beverages led to an increase of sterol and metabolite excretion (with the exception of coprostanol, which decreased) and to slight changes in women’s capacities for sterol conversion, regardless of the GOS presence. This study demonstrates the suitability of simultaneous enrichment with PS and GOS in milk-based fruit beverages, considering their hypocholesterolemic effect.
