Introduction
Reflection on the impact of this law on people with a Mental health disorder is required. It is a complex issue, in which it must be considered that these disorders are very prevalent, ...can greatly affect the quality of life and are often resistant to treatment.
Objectives
Explore the first request of this type and review aspects to consider in patients with mental health disorders.
Methods
Collection of data from the first patient who requests it and review related aspects.
Results
This is a patient with a personality disorder who presents significant suffering, in a chronic context, but at the same time makes the request in a moment of crisis as an impulsive gesture.
Conclusions
Pending evolution, we consider that it is difficult to assess compliance with the requirements of the law in patients of this type and we recommend caution.

During the moulding of polymeric pieces, the important temperatures involved, and the gases produced by decomposition of components from the polymer can induce corrosion on the working surface of the ...steel mould. Polymers can also stick to the mould surface, being their separation (demoulding) one of the critical aspects in their processing. Demoulding agents typically used in this process are expected to contribute in some extend to protect the mould against corrosion. In this work, hybrid sol-gel technology for anti-adherent coatings presented in previous papers is extended to formulations doped with different metallic precursors of proven chemical and wear resistance such as Zn, Ti, and Zr, with the aim to increase the corrosion resistant at the same time that keep good demoulding properties. Different synthetic routes one-pot or two components were followed depending on the doped agent. Sol-gel formulations were applied onto steel substrates by controlled dip coating technique, resulted in ultra-thin films of ∼0.15 µm, being capable to protect micro texturized steel moulds. Hardness of these films was superior (10H) to those formulations with fluorosilane and PDMS used as reference. Corrosion protection was evaluated obtaining good results in both polarization resistance and corrosion rate for Zn (5232 Ω × cm

, 0.08 mm/year), protecting the bare steel up to 6.5 times more in terms of annual corrosion, followed by Zr and Ti. Their behaviour as anti-adherent coating was also discussed and compared with fluorosilane and PDMS-based coatings.
Objectives
The aim of the study was to investigate whether very low level viraemia (VLLV) (20–50 HIV‐1 RNA copies/mL) was associated with increased risk of virological failure (VF) as compared with ...persistent full suppression (< 20 copies/mL).
Methods
From the VACH Cohort database, we selected those patients who started antiretroviral therapy (ART) after January 1997 and who achieved effective viral suppression two consecutive viral loads (VLs) < 50 copies/mL followed by full suppression (at least one VL <20 copies/mL). We carried out survival analyses to investigate whether the occurrence of VLLV rather than maintaining full suppression at < 20 copies/mL was associated with virological failure (two consecutive VLs > 200 copies/mL or one VL > 200 copies/mL followed by a change of ART regimen, administrative censoring or loss to follow‐up), adjusted for nadir CD4 cell count, sex, age, ethnicity, transmission group, type of ART and time on effective suppression at < 50 copies/mL.
Results
Of 21 480 patients who started ART, 13 674 (63.7%) achieved effective suppression at < 50 copies/mL, of whom 4289 (31.4%) further achieved full suppression at < 20 copies/mL after May 2009. A total of 2623 patients (61.1%) remained fully suppressed thereafter, while 1666 had one or more episodes of VL detection > 20 copies/mL (excluding virological failure). A total of 824 patients had VLLV after suppression at < 20 copies/mL. VLLV was not associated with virological failure as compared with persistent full suppression hazard ratio (HR) 0.67; 95% confidence interval (CI) 0.44–1.00, independently of the number of blips recorded (from one to 18).
Conclusions
In our population of HIV‐infected patients on ART who achieved viral suppression at < 20 copies/mL, the risk of virological failure was no different for patients who remained fully suppressed compared with those who experienced subsequent episodes of VLLV.
To determine the prevalence and incidence of pediatric acute respiratory distress syndrome (pARDS) among infants and children admitted to the PICU.
A single-center descriptive point prevalence study ...with twice weekly data collection over a 6 months (August 2020 to February 12, 2021).
Red Cross War Memorial Children's Hospital, Cape Town, South Africa.
All infants and children admitted to the PICU on study days were included.
Data were captured electronically on a standardized case record form using a Research Electronic Data Capture electronic database.
The Pediatric Acute Lung Injury Consensus Conference criteria were used to define pARDS cases. Prevalence was calculated as the total number of pARDS cases/1,000 PICU bed days. The study included 354 patients (median interquartile range) 10.1 months old (1.5-61.3 mo old), with 204 males (57.6%), who occupied 879 bed days. Of these 879 bed days, 266 (30.3%; 95% CI, 27.2-33.3%) were occupied by pARDS cases, with a calculated prevalence and incidence of 302.6 of 1,000 bed days (30.3%) and 29.7% (95% CI, 26.7-32.7%), respectively. Three cases from the cohort were defined using the oxygen saturation index calculation. In cases receiving invasive ventilation ( n = 494; 56.2%), pARDS severity was classified as mild ( n = 143; 16.3%), moderate ( n = 44; 5.0%), and severe ( n = 29, 3.3%). A further 205 beds (23.3%) were occupied by patients classified as being at risk of pARDS.
The prevalence and incidence of pARDS in a South African PICU appears substantially higher than findings described in international reports. Further investigation of risk factors and outcomes is warranted.
Summary Background While numerous papers have reported on the biological mechanisms of human hair pigmentation and greying, epidemiological descriptions of both natural hair colour and the greying ...process, worldwide, remain scarce.
Objectives To assess hair colour and greying in a large world sample of human subjects, and to revisit the validity of the 50/50/50 rule of thumb, which states that ‘at age 50 years, 50% of the population has at least 50% grey hair’.
Methods The natural hair colour of 4192 healthy male and female volunteers was assessed using a sensorial expert evaluation through the comparison of each volunteer’s hair with standard swatches. Hair colour was studied according to age, gender and ethnic or geographical origin.
Results Overall we observed that between 45 and 65 years of age, 74% of people were affected by grey hair with a mean intensity of 27%. Men harboured significantly more grey hair than women. Both age at onset and rate of greying with age appeared to be clearly linked to ethnic/geographical origin. Subjects of Asian and African descent showed less grey hair than those of caucasian origin, at comparable ages, confirming previously reported data.
Conclusions Calculating the percentage of people showing at least 50% grey hair coverage at age 50 years leads to a global range of 6–23%, according to ethnic/geographical origin and natural hair colour: well below that expressed by the ‘50’ rule of thumb.
Coxsackievirus B (CVB) enteroviruses are common human pathogens known to cause severe diseases including myocarditis, chronic dilated cardiomyopathy, and aseptic meningitis. CVBs are also ...hypothesized to be a causal factor in type 1 diabetes. Vaccines against CVBs are not currently available, and here we describe the generation and preclinical testing of a novel hexavalent vaccine targeting the six known CVB serotypes. We show that the vaccine has an excellent safety profile in murine models and nonhuman primates and that it induces strong neutralizing antibody responses to the six serotypes in both species without an adjuvant. We also demonstrate that the vaccine provides immunity against acute CVB infections in mice, including CVB infections known to cause virus-induced myocarditis. In addition, it blocks CVB-induced diabetes in a genetically permissive mouse model. Our preclinical proof-of-concept studies demonstrate the successful generation of a promising hexavalent CVB vaccine with high immunogenicity capable of preventing CVB-induced diseases.
Electronic portal imaging devices (EPIDs) lend themselves to beams-eye view clinical applications, such as tumor tracking, but are limited by low contrast and detective quantum efficiency (DQE). We ...characterize a novel EPID prototype consisting of multiple layers and investigate its suitability for use under clinical conditions. A prototype multi-layer imager (MLI) was constructed utilizing four conventional EPID layers, each consisting of a copper plate, a Gd2O2S:Tb phosphor scintillator, and an amorphous silicon flat panel array detector. We measured the detector's response to a 6 MV photon beam with regards to modulation transfer function, noise power spectrum, DQE, contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and the linearity of the detector's response to dose. Additionally, we compared MLI performance to the single top layer of the MLI and the standard Varian AS-1200 detector. Pre-clinical imaging was done on an anthropomorphic phantom, and the detector's CNR, SNR and spatial resolution were assessed in a clinical environment. Images obtained from spine and liver patient treatment deliveries were analyzed to verify CNR and SNR improvements. The MLI has a DQE(0) of 9.7%, about 5.7 times the reference AS-1200 detector. Improved noise performance largely drives the increase. CNR and SNR of clinical images improved three-fold compared to reference. A novel MLI was characterized and prepared for clinical translation. The MLI substantially improved DQE and CNR performance while maintaining the same resolution. Pre-clinical tests on an anthropomorphic phantom demonstrated improved performance as predicted theoretically. Preliminary patient data were analyzed, confirming improved CNR and SNR. Clinical applications are anticipated to include more accurate soft tissue tracking.
