This study described the epidemiology and geographical distribution of people diagnosed with HIV in Kerman, Iran, between 1997 and 2020.

We used case-based HIV surveillance data of all people diagnosed with HIV in Kerman between 1997 and 2020. We compared the age, gender, modes of transmission and spatial distribution of newly diagnosed HIV-infected people in three time periods (1997-2004, 2005-2012 and 2013-2020). The χ
test for trend, one-sample t-test and Kruskal-Wallis H test were used to compare the differences between the three time periods. We also used ArcGIS to map both HIV services and people living with HIV (PLWH) in 2020. The nearest neighbour index and kernel density were used to identify the spatial distribution of PLWH.

A total of 459 (27.5% women) people were diagnosed with HIV during 1997-2020. The proportion of women (9.3% in 1997-2004 and 48.3% in 2013-2020, p<0.001), HIV infection through sexual contacts (11.6% in 1997-2004 and 50.3% in 2013-2020, p<0.001), HIV infection under the age of 5 years (0.8% in 1997-2004 and 5.4% in 2013-2020, p=0.01) and mean age at diagnosis among men (34.9 in 1997-2004 and 39.8 years in 2013-2020, p=0.004) significantly increased over time. 36.2% of diagnosed cases had CD4 counts under 200 x 10ˆ6/L between 2013 and 2020, with no significant improvement over time. Most newly diagnosed cases of HIV were from the eastern parts of the city. The clusters of PLWH in 2020 matched with the locations of HIV services.

We observed important changes in HIV epidemiology regarding gender, modes of transmission, number of paediatric cases and density maps over time in Kerman. These changes should be considered for precise targeting of HIV prevention and treatment programmes.

HIV self-tests (HSTs) have been deployed to reduce the burden of undiagnosed HIV infections in subpopulations undertested. We assumed that patients attending sexual health centres could themselves distribute HSTs in their close network. This study aimed to assess the proportion and the characteristics of the participants who distributed HSTs, as well as the characteristics of people who received HSTs.

Three HSTs were given to patients attending "Le 190" Sexual Health Center, Paris, France, having consented for the study, between July 2018 and August 2020. Participants had to distribute HSTs within 6 months, preferably to individuals in their close circle who have not been tested for a long time. Then they had to complete a self-questionnaire, exploring HIV status, sexual practices, number of distributed HSTs, profile of persons who received HSTs, and if known, result of used HSTs. Univariable logistic regression was used to determine factors associated with HST distribution.

Overall, 682/1062 (64%) patif HSTs, targeting a population with high level of undiagnosed HIV infections, especially if they have already experimented it.
The COVID-19 pandemic has had variable effects on the rates of STIs reported across the globe. This study sought to assess how the number of STI reports changed during the pandemic in Japan.

We used national infectious disease surveillance data from the National Institute of Infectious Diseases (Tokyo, Japan) for the period between January 2013 and December 2021. We compared reported rates of chlamydia, gonorrhoea, condyloma acuminata and genital herpes, as well as total notifications for HIV/AIDS and syphilis during the pandemic versus previous years in Japan. We used a quasi-Poisson regression to determine whether any given week or month between January 2018 and December 2021 had a significant excess or deficit of STIs. Notification values above or below the 95% upper and lower prediction thresholds were considered as statistically significant. The start of the pandemic was defined as January 2020.

Chlamydia generally remained within predicted range during the pandemic period. Reporting of gonorrhoea porting of STIs in Japan. Higher-than-predicted reporting was more likely to be observed in the later phases of the pandemic. These changes may have been attributable to pandemic-related changes in sexual behaviour and decreased STI clinic attendance and testing, but further research on the long-term impact of the pandemic on STIs is necessary.
We sought to quantify the use of person-centred language (PCL) in research journals that publish high volumes of HIV-related manuscripts.

In this cross-sectional study, we searched PubMed for HIV-related articles published between 1 January 2017 and 7 March 2021. After journal reduction and article randomisation, title and abstract screening was conducted among 500 studies in a masked, duplicate fashion.

Studies that were included were systematically searched for prespecified, stigmatising terms, partial terms and phrases. Prevalence rates of non-person-centred terminology were totalled, and the total number of articles adherent to PCL guidelines were reported. Fisher's exact tests were used to determine associations between PCL adherence and article funding source, type of article, continent of origin and research, among others.

Among 237 studies included, 21.52% (51) of HIV-related publications in this cross-sectional analysis were found to be PCL adherent. Stigmatising labels such as 'HIV- or AIDS-e of person-centred language in medical research has the potential to minimise the use of stigmatising language among medical professionals, in medical education, in medical records and patient encounters, and thus reduce stigma.
We evaluated a real-time quantitative PCR (qPCR) for detection of the
(TP) genome in clinical samples through simultaneous detection of two genomic targets.

We performed qPCR with TaqMan technology using two TP genes,
and
, as targets, with an internal positive control. The qPCR assay was compared with syphilis diagnosis based on a combination of clinical examination, serological results and inhouse nested PCR (nPCR). Samples were analysed at the National Reference Center for STIs at Cochin Hospital in Paris.

In total, from October 2010 to December 2016, 320 documented clinical samples (mucosal and cutaneous swabs) were collected from patients with or without syphilis attending STI centres in France. The qPCR had an overall sensitivity of 89% (95% CI 85.1% to 92.1%), a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 88% (95% CI 84.3% to 91.5%). The agreement between qPCR and nPCR results was 94% (
=0.88, 95% CI 0.83 to 0.93). Calibration of the qPCR assay, by cloning both the
and
genes, defined the detection threshold as 1 copy/µL of DNA elution.

We validated a new qPCR for detecting the TP genome in clinical samples with excellent sensitivity and specificity. The cloning of
and
genes for calibration would be interesting in the evaluation of bacterial loads in samples.

To explore patients' agreement and reasons for agreement or disagreement with the EULAR recommendations for patient education (PE) for people with inflammatory arthritis (IA).

This mixed-method survey collected data using snowball sampling. The survey had been translated into 20 languages by local healthcare professionals, researchers and patient research partners. It explored the degree to which patients with IA agreed with each recommendation for PE (0=do not agree at all and 10=agree completely) and their rationale for their agreement level in free text questions. Descriptive statistics summarised participants' demographics and agreement levels. Qualitative content analysis was used to analyse the free text data. Sixteen subcategories were developed, describing the reasons for agreement or disagreement with the recommendations, which constituted the categories.

The sample comprised 2779 participants (79% female), with a mean (SD) age 55.1 (13.1) years and disease duration 17.1 (13.3) years. Participareement levels were very high, suggesting that they reflect patients' preferences for engaging in collaborative clinical care and using PE to facilitate and supplement their own understanding of IA. Reasons for not completely agreeing with the recommendations can inform implementation strategies and education of healthcare professionals.
Menthol masks the harshness of cigarette smoke, promotes youth smoking and encourages health-concerned smokers who incorrectly believe that menthols are less harmful to smoke menthols. This study of smokers in Kenya and Zambia is the first study in Africa to examine menthol use, smokers' beliefs about its harmfulness and the factors associated with menthols.

Data were from the International Tobacco Control (ITC) Kenya Wave 2 (2018) and Zambia Wave 2 Survey (2014), involving nationally representative samples of smokers. This study focuses on 1246 adult smokers (644 in Kenya, 602 in Zambia) who reported smoking a usual brand of cigarettes (menthol or non-menthol).

Overall, menthol use was significantly higher among smokers in Zambia than in Kenya (48.0% vs 19.0%), females (45.6% vs 31.2% males), non-daily smokers (43.8% vs 30.0% daily) and those who exclusively smoked factory-made (FM) cigarettes (43.0% vs 15.2%). The erroneous belief that menthols are less harmful was more likely among smokers in Zambia combat the myth that menthols are less harmful and to ban menthol and other flavourings.In eukaryotic cells, intron lariats produced by the spliceosome contain a 2'5' phosphodiester linkage. The RNA lariat debranching enzyme, Dbr1, is the only enzyme known to hydrolyze this bond. Dbr1 is a member of the metallophosphoesterase (MPE) family of enzymes, and recent X-ray crystal structures and biochemistry data demonstrate that Dbr1 from Entamoeba histolytica uses combinations of Mn2+, Zn2+, and Fe2+ as enzymatic cofactors. Here, we examine the kinetic properties and metal dependence of the Dbr1 homolog from Saccharomyces cerevisiae (yDbr1). Elemental analysis measured stoichiometric quantities of Fe and Zn in yDbr1 purified following heterologous expression E. coli We analyzed the ability of Fe2+, Zn2+, and Mn2+ to reconstitute activity in metal-free apoenzyme. Purified yDbr1 was highly active, turning over substrate at 5.6 sec-1, and apo-yDbr1 reconstituted with Fe2+ was the most active species, turning over at 9.2 sec-1 We treated human lymphoblastoid cells with the iron-chelator deferoxamine and measured a twofold increase in cellular lariats. These data suggest that Fe is an important biological cofactor for Dbr1 enzymes.This study characterised the hemidiaphragm elevation on 3-month interval chest X-rays (CXRs) of patients post COVID-19 pneumonia. 467 CXRs were screened; 19 (4.1%) had an elevated hemidiaphragm. There were 15 (3.2%) patients of interest with new hemidiaphragm elevation, persisting on average 7 months post COVID-19 diagnosis. Symptomatic patients underwent diaphragm ultrasound (n=12), pulmonary function test (n=10), muscle function test (n=6) and neurophysiology (n=5), investigating phrenic nerve function. Ultrasound demonstrated reduced/paradoxical diaphragmatic movements in eight; four of eight had reduced thickening fraction. Neurophysiology peripheral limb studies did not support the differential diagnoses of critical illness neuropathy/myopathy. We propose that, in selected patients, COVID-19 may cause phrenic nerve mononeuritis.
