Abstract

Background: Although people with HIV might be at risk of severe outcomes from infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2; coronavirus 2019 [COVID‐19]), regional and temporal differences in SARS‐CoV‐2 testing in people with HIV across Europe have not been previously described. Methods: We described the proportions of testing, positive test results, and hospitalizations due to COVID‐19 between 1 January 2020 and 31 December 2021 in the EuroSIDA cohort and the factors associated with being tested for SARS‐CoV‐2 and with ever testing positive. Results: Of 9012 participants, 2270 (25.2%, 95% confidence interval [CI] 24.3–26.1) had a SARS‐CoV‐2 polymerase chain reaction test during the study period (range: 38.3% in Northern to 14.6% in Central‐Eastern Europe). People from Northern Europe, women, those aged <40 years, those with CD4 cell count <350 cells/mm3, and those with previous cardiovascular disease or malignancy were significantly more likely to have been tested, as were people with HIV in 2021 compared with those in 2020. Overall, 390 people with HIV (4.3%, 95% CI 3.9–4.8) tested positive (range: 2.6% in Northern to 7.1% in Southern Europe), and the odds of testing positive were higher in all regions than in Northern Europe and in 2021 than in 2020. In total, 64 people with HIV (0.7%, 95% CI 0.6–0.9) were hospitalized, of whom 12 died. Compared with 2020, the odds of positive testing decreased in all regions in 2021, and the associations with cardiovascular disease, malignancy, and use of tenofovir disoproxil fumarate disappeared in 2021. Among study participants, 58.9% received a COVID‐19 vaccine (range: 72.0% in Southern to 14.8% in Eastern Europe). Conclusions: We observed large heterogeneity in SARS‐CoV‐2 testing and positivity and a low proportion of hospital admissions and deaths across the regions of Europe. [ABSTRACT FROM AUTHOR]

Abstract

Objectives: The aim of this study was to assess the impact of hepatitis B virus (HBV) infection on non-liver malignancies in people living with HIV (PLWH). Methods: All persons aged ≥18 years with known hepatitis B virus (HBV) surface antigen (HBsAg) status after the latest of 1January 2001 and enrolment in the EuroSIDA cohort (baseline) were included in the study; persons were categorized as HBV positive or negative using the latest HBsAg test and followed to their first diagnosis of nonliver malignancy or their last visit. Results: Of 17485 PLWH included in the study, 1269 (7.2%) were HBV positive at baseline. During 151766 person-years of follow-up (PYFU), there were 1298 nonliver malignancies, 1199 in those currently HBV negative [incidence rate (IR)8.42/1000 PYFU; 95% confidence interval (CI) 7.94–8.90/1000 PYFU] and 99 in those HBV positive (IR10.54/1000 PYFU; 95% CI8.47–12.62/1000 PYFU). After adjustment for baseline confounders, there was a significantly increased incidence of nonliver malignancies in HBV-positive versus HBV-negative individuals [adjusted incidence rate ratio (aIRR)1.23; 95% CI 1.00–1.51]. Compared to HBV-negative individuals, HBsAg-positive/HBV-DNA-positive individuals had significantly increased incidences of nonliver malignancies (aIRR 1.37; 95% CI 1.00–1.89) and NHL (aIRR 2.57; 95% CI 1.16–5.68). There was no significant association between HBV and lung or anal cancer. Conclusions: We found increased rates of nonliver malignancies in HBsAg-positive participants, the increases being most pronounced in those who were HBV DNA positive and for NHL. If confirmed, these results may have implications for increased cancer screening in HIV-positive subjects with chronic HBV infection.

Abstract

Background: In a 2013 survey, we reported distinct discrepancies in delivery of tuberculosis (TB) and HIV services in eastern Europe (EE) vs. western Europe (WE). Objectives: To verify the differences in TB and HIV services in EE vs. WE. Methods: Twenty-three sites completed a survey in 2018 (EE, 14; WE, nine; 88% response rate). Results were compared across as well as within the two regions. When possible, results were compared with the 2013 survey. Results: Delivery of healthcare was significantly less integrated in EE: provision of TB and HIV services at one site (36% in EE vs. 89% in WE; P = 0.034), and continued TB follow-up in one location (42% vs. 100%; P = 0.007). Although access to TB diagnostics, standard TB and HIV drugs was generally good, fewer sites in EE reported unlimited access to rifabutin/multi-drug-resistant TB (MDR-TB) drugs, HIV integrase inhibitors and opioid substitution therapy (OST). Compared with 2013, routine usage of GeneXpert was more common in EE in 2018 (54% vs. 92%; P = 0.073), as was access to moxifloxacin (46% vs. 91%; P = 0.033), linezolid (31% vs. 64%; P = 0.217), and bedaquiline (0% vs. 25%; P = 0.217). Integration of TB and HIV services (46% vs. 39%; P = 1.000) and provision of OST to patients with opioid dependency (54% vs. 46%; P = 0.695) remained unchanged. Conclusion: Delivery of TB and HIV healthcare, including integration of TB and HIV care and access to MDR-TB drugs, still differs between WE and EE, as well as between individual EE sites.

Abstract

В соответствии с теорией протекания предложен подход, позволяющий на основе анализа количества и расположения выходов каналов на поверхности пен, оценить их проницаемость для эвакуации газа при получении водорода щелочным электролизом. Увеличение «массы» бесконечного кластера и числа связей коррелирует с уменьшением катодного перенапряжения. An approach based on percolation theory allows estimating channels permeability for hydrogen evacuation during alkaline electrolysis. Estimation is based on the analysis of number and location of channels on the foams surface. An increase in the infinite cluster “mass” and in the bonds number correlate with cathodic overvoltage decrease.

Abstract

Установлено, что природа ионов металла, разряжающихся на катоде, оказывает значительное влияние на морфологию осадка. Осадки никеля обладают характерной структурой пены: на них присутствуют крупные поры (каналы эвакуации водорода), вокруг которых кристаллизуется металл в форме дендритов. Осадки сплава Ni–Co по своей морфологии близки к рыхлым порошкообразным металлам. It was found that the nature of metal ions discharged at the cathode has a significant effect on the deposit morphology. Pure nickel deposits have a typical foam structure with large pores composed of dendrites. The Ni-Co alloy deposits are characterized by morphology close to loose powder metals.
