Abstract
BACKGROUND To evaluate drug use (alcohol, tobacco, cannabis and other drugs) and its association with mean CD4/CD8 T cell count ratio, a marker of chronic inflammation, in virally suppressed people living with HIV-1 (PLWH) in Nouvelle Aquitaine, France. METHODS A multi-centric, cross-sectional analysis was conducted in 2018-19 in the QuAliV study-ANRS CO3 AQUIVIH-NA cohort. Tobacco, alcohol, cannabis, and other drug use (poppers, cocaine, amphetamines, synthetic cathinones, GHB/GBL) were self-reported. CD4 and CD8 T cell counts and viral load measures, ± 2 years of self-report, and other characteristics were abstracted from medical records. Univariable and multivariable linear regression models, adjusted for age, sex, HIV risk group, time since HIV diagnosis, and other drug use were fit for each drug and most recent CD4/CD8 ratio. RESULTS 660 PLWH, aged 54.7 ± 11.2, were included. 47.7% [315/660] had a CD4/CD8 ratio of < 1. Their mean CD4/CD8 ratio was 1.1 ± 0.6. 35% smoked; ~ 40% were considered to be hazardous drinkers or have alcohol use disorder; 19.9% used cannabis and 11.9% other drugs. Chemsex-associated drug users' CD4/CD8 ratio was on average 0.226 (95% confidence interval [95% CI] - 0.383, - 0.070) lower than that of non-users in univariable analysis (p = 0.005) and 0.165 lower [95% CI - 0.343, 0.012] in multivariable analysis (p = 0.068). CONCLUSIONS Mean differences in CD4/CD8 ratio were not significantly different in tobacco, alcohol and cannabis users compared to non-users. However, Chemsex-associated drug users may represent a population at risk of chronic inflammation, the specific determinants of which merit further investigation. TRIAL REGISTRATION NUMBER NCT03296202.

Abstract
BACKGROUND Severe non-AIDS bacterial infections (SBIs) are one of the leading causes of hospital admissions among persons with HIV (PWH) in regions with high ART coverage. METHODS This large prospective cohort study of PWH examined the types of infections, bacterial documentation, and evolution of antibiotic resistance among PWH hospitalized with SBIs over an 18-year period. RESULTS Between 2000 and 2017, 459 PWH had at least one SBI with bacterial documentation. Among the 847 SBIs, there were 280 cases of bacteremia, 269 cases of pneumonia, and 240 urinary tract infections. The 1025 isolated bacteria included Enterobacteriaceae (n = 394; mainly Escherichia coli), Staphylococcus aureus (n = 153) and Streptococcus pneumoniae (n = 82). The proportion of S. pneumoniae as the causative agent in pneumonia and bacteremia decreased sharply over time, from 34% to 8% and from 21 to 3%, respectively.The overall antibiotic resistance of S. aureus and S. pneumoniae decreased progressively but it increased for Enterobacteriaceae (from 24% to 48% for amoxicillin-clavulanate, from 4 to 18% for cefotaxime, and from 5% to 27% for ciprofloxacin). Cotrimoxazole prophylaxis was associated with higher nonsusceptibility of S. pneumoniae to amoxicillin and erythromycin, higher nonsusceptibility of Enterobacteriaceae to beta-lactams and fluoroquinolones, and a higher risk of extended-spectrum β-lactamase producing Enterobacteriaceae. CONCLUSIONS The bacterial resistance pattern among PWH between 2014 and 2017 was broadly similar to that in the general population, with the exception of a higher resistance profile of Enterobacteriaceae to fluoroquinolones. The use of cotrimoxazole as prophylaxis was associated with an increased risk of antibiotic resistance.

Abstract
INTRODUCTION Ultrasound imaging has many clinical applications, but there is a lack of data about its use by infectiologists. The aim of this study was to describe ultrasound performed routinely by infectiologists and to assess the diagnostic performance of ultrasound with aspirate and fluid analysis in prosthetic joint infections. METHODS Retrospective study between 1st June 2019 and 1st June 2020 in an infectious and tropical diseases unit in a tertiary University Hospital. RESULTS One hundred and thirty-one ultrasounds were performed on 127 patients by the infectious diseases team. These included 64 musculoskeletal ultrasounds (31 in native joints and 33 in prosthetic joints including 15 knees, 13 hips and 5 spacers) and 33 led to a fluid aspirate. Fourteen lung ultrasounds were done, 11 confirmed pneumopathy and 7 resulted in pleural puncture. Twenty-three vascular ultrasounds were done, 17 to insert a catheter, and four to perform a blood test. Five ultrasounds explored adenopathy, of which one node tuberculosis and one Bartonella infection were diagnosed. In prosthetic joint infections, sensitivity and specificity of ultrasound with fluid aspirate and analysis were respectively 100% and 100% for the knee and 40% and 100% for the hip. CONCLUSION Ultrasound performed by infectiologists is useful and contributes to a faster diagnosis. Furthermore, the specificity of ultrasound with aspirate and fluid analysis is very high in prosthetic joint infection. Ultrasound training courses should be considered for infectiologists including residents.

Abstract
Rotatory subluxation of the atlantoaxial joint in adults is a rare, but potentially life-threatening injury. Delayed or missed diagnosis can lead to catastrophic consequences. Early recognition and prompt treatment is paramount to avoid long-term morbidity and disability. We report on an instance of bilateral atlantoaxial rotatory subluxation (AARS) in a 25-year-old female who presented to the Casualty Department with a painful neck, right-sided hemiparesis and torticollis after a road traffic collision. Reduction was achieved by controlled cervical traction followed by immobilization in a four-post Halo brace, with complete resolution of her symptoms. At the 12-month follow-up, she had normal neck movements with no signs of instability.

Abstract
Of the 176 randomly selected, commensal, gram-negative bacteria isolated from healthy children with low exposure to antibiotics, 138 (78%) carried one or more of the seven macrolide resistance genes tested in this study. These isolates included 79 (91%) isolates from the oral cavity and 59 (66%) isolates from urine samples. The mef(A) gene, coding for an efflux protein, was found in 73 isolates (41%) and was the most frequently carried gene. The mef(A) gene could be transferred from the donors into a gram-positive E. faecalis recipient and a gram-negative Escherichia coli recipient. The erm(B) gene transferred and was maintained in the E. coli transconjugants but was found in 0 to 100% of the E. faecalis transconjugants tested, while the other five genes could be transferred only into the E. coli recipient. The individual macrolide resistance genes were identified in 3 to 12 new genera. Eight (10%) of the oral isolates and 30 (34%) of the urine isolates for which the MICs were 2 to >500 microg of erythromycin per ml did not hybridize with any of the seven genes and may carry novel macrolide resistance genes.

Abstract
Little is known about carriage of Candida albicans, the predominant pathogenic yeast in oral infection, in children. We cultured buccal mucosal and gingival swabs from 150 Portuguese children to investigate the prevalence of C. albicans at baseline (before dental treatment), post-treatment, and 12, 24, and 36 months post-baseline. The children, aged 8 to 11 years at baseline, had no systemic disease or clinical symptoms of oral candidiasis. At each successive visit, respectively, 47, 32, 21, 27, and 28% of children were C. albicans positive, resulting in an almost 50% reduction in prevalence from baseline to post-treatment (P < 0.0005). Children who carried C. albicans at one visit had 3 to 20 times greater odds of carrying C. albicans at another visit. C. albicans was cultured from 12 children at all time-points and from 10 children at four time-points. Children with oral C. albicans frequently maintained carriage over time, even with regular dental care.

Abstract
Twenty-nine patients with pyogenic vertebral osteomyelitis were reviewed retrospectively after an average follow-up of 3.7 years. We identified 17 patients with predisposing factors (10 diabetes, 4 urinary tract infection, 2 HIV-positive, 1 rheumatoid arthritis). No patient presented with a febrile illness. The lumbar spine was involved in 15 patients. Eighteen patients had neurological impairment at presentation. Eleven patients who were neurologically intact had needle biopsies and the remaining 18 patients who were neurologically compromised had an open decompression. Staphylococcus aureus was cultured in 14 patients. Although spinal tuberculosis is relatively common in our environment it is important to obtain a tissue diagnosis in order to exclude pyogenic vertebral osteitis.

Abstract
In the period from May through June 1994, an increase in the number of domestic cases of Shigella sonnei infection was detected in several European countries, including Norway, Sweden, and the United Kingdom. In all three countries epidemiological evidence incriminated imported iceberg lettuce of Spanish origin as the vehicle of transmission. The outbreaks shared a number of common features: a predominance of adults among the case patients, the presence of double infections with other enteropathogens, and the finding of two dominant phage types among the bacterial isolates. In Norway 110 culture-confirmed cases of infection were recorded; more than two-thirds (73%) were adults aged 30 to 60 years. A nationwide case-control study comprising 47 case patients and 155 matched control individuals showed that the consumption of imported iceberg lettuce was independently associated with an increased risk of shigellosis. Epidemiological investigation of a local outbreak incriminated iceberg lettuce from Spain, consumed from a salad bar, as the source. The presence of shigellae in the suspected food source could not be documented retrospectively. However, high numbers of fecal coliforms were detected in iceberg lettuce from patients' homes. Three lettuce specimens yielded salmonellae. The imported iceberg lettuce harbored Escherichia coli strains showing resistance to several antimicrobial agents, including ampicillin, ciprofloxacin, gentamicin, and trimethoprim-sulfamethoxazole. During the outbreak it is likely that thousands of Norwegians and an unknown number of consumers in other countries were exposed to coliforms containing antibiotic resistance genes.

Abstract
Production of aflatoxins by Aspergillus ruber THOM and CHURCH was first reported by KULIK and HOLADAY (1967), although these results have lacked confirmation. In this paper we provide evidence that this fungal strain produces aflatoxins. This finding has implications for food hygiene, especially in countries where such moulds are used in the preparation of foodstuffs.

Abstract
Synchronized root meristems of Pisum sativum were treated at each phase of the cell cycle with 6.25 mM N-nitroso-N-ethylurea. DNA extracted from treated cells and run in agarose gel electrophoresis exhibits a series of discrete fragments with length below 2500 bp and a significant number of unspecific single-stranded breaks (or alkali-labile sites). Experiments with micrococcal nuclease indicated that the nucleosomal organization of the chromatin is not responsible for the generation of the discrete fragments: it seems that their appearance is associated with a preferable attack of the mutagen at specific sites, characteristic for the plant genome. Moreover, a cell cycle dependent release of the discrete fragments was found with maximum at G1-S and minimum at mitosis. The model experiments designed to clarify this observation suggest that it might be determined from the cell cycle dependent fluctuation in the accessibility of the chromatin DNA and/or the process of excision-repair.

Abstract
Phosphine is a food fumigant, used until now as an insecticide and rodenticide. The present work researches the action of phosphine treatment on growth and aflatoxin production of 23 Aspergillus strains. Production of aflatoxins B1, B2, G1, and G2 decreased in almost all cases by a ratio of 10 to 100. Phosphine treatment therefore seems favorable to prevent growth of various Aspergillus strains, in the context of keeping food safe.

Abstract
The examinations were performed in 418 patients with malignancy or an ulcer of the stomach. In all cases the Cancer Registry of Norway was asked for the final diagnosis and date of death. The diagnosis of malignancy was based on histology on operated or autopsy specimens, and the surviving cases were re-examined by answering a questionnaire. At the time of the primary examination a total of 103 cases of malignancies were found, of whom 41 were women. 84 patients had not been operated on previously. Among these 7 cases of early carcinoma were found. In 19 patients a partial gastrectomy had been performed. A false diagnosis of benign lesion was given on biopsy in 2 per cent, by gastroscopy in 8, and by X-ray examination in 31 per cent. A definite diagnosis of malignancy was made correctly by the same procedures in 95, 53 and 16 per cent, respectively. After 30 months of observation 16 cases of malignant lesions were reported among the patients (315) who had an ulcer of the stomach with benign histology on directed biopsy at the primary examination. A false benign diagnosis had been made in 33 per cent of 119 with malignancy by X-ray examination, in 10 per cent by gastroscopy, and in 15 per cent by histology on biopsy. The corresponding percentages in the total material of cases with benign and malignant lesions were 10.2, 2.9, and 4.3, respectively. In cases with previous partial gastrectomy, and in those with early cancers much higher rates of false negative diagnosis of malignancy has so far been suggested in 12 per cent of cases with benign ulcers, a gastroscopical diagnosis has been suggested in 22 per cent, and a bioptical in none. A combination of diagnostic procedures provided a correct diagnosis of malignancy in 118 out of 119 patients.
