Recent infection testing algorithms (RITAs) incorporating clinical information with the HIV recency assay have been proven to accurately classify recent infection. However, little evidence exists on whether RITAs would help in precisely identifying major drivers of the ongoing HIV epidemic.

HIV recency test results and clinical information were collected from 1152 newly diagnosed HIV cases between 2015 and 2017 in Dehong prefecture of Yunnan province, and the efficacy of four different RITAs in identifying risk factors for new HIV infection was compared.

RITA 1 uses the recency test only. RITA 2 and RITA 3 combine the recency test with CD4+ T cell count and viral load (VL), respectively. RITA 4 combines both CD4+ T cell count and VL. All RITAs identified the MSM group and young people between 15 and 24 years as risk factors for incident HIV infection. RITA 3 and RITA 4 further identified the Dai ethnic minority as a risk factor, which had not been identified before when only the HIV recency test was used.

By comparing different RITAs, we determined that greater accuracy in classifying recent HIV infection could help elucidate major drivers impacting the ongoing epidemic and thus inform targeted interventions.

Synthesis of the available evidence on the effectiveness of medical and cloth facemask use by the general public in community settings is required to learn lessons for future respiratory epidemics/pandemics.

Search terms relating to facemasks, infection and community settings were used for PubMed, the Cochrane Library Database and Google Scholar. A meta-analysis was conducted using a random-effects model.

The review included 12 primary studies on the effectiveness of medical facemask use to prevent influenza, influenza-like illness, SARS-CoV, and SARS-CoV-2 transmission. The meta-analysis demonstrated that facemask use significantly reduces the risk of transmitting these respiratory infections (pooled OR = 0.66, 95% CI 0.54-0.81). Of the 12 studies, 10 clinical trials suggested that respiratory infection incidence is lower with high medical facemask compliance, early use and use in combination with intensive hand hygiene. One cohort study conducted during the SARS-CoV-2 pandemic demonstrated that facema is dependent on compliance and utilization in combination with preventive measures such as intensive hand hygiene. No direct evidence is currently available in humans supporting the recommendation of cloth facemask use to prevent respiratory infection transmission.
An acute respiratory disease caused by a novel coronavirus (SARSCOV2) is spreading from China since January 2020. Surprisingly, few cases of Covid-19 have been reported in people living with HIV (PLWHIV).

Here we present a series of 30 PLWHIV diagnosed for SARS-COV2 infection. The principal outcome was to describe clinical characteristics of this population.

Eighteen (60%) patients were men, 10/30 (33,3%) women and 2/30 (6,7%) transgender women. Median age was 53,7 years (range 30-80 years) and 23/30 patients (76,7%) were born in a foreign country (out of France). The most common comorbidities were cardiovascular disease (11/30, 36,7%), hypertension (11/30, 36,7%), diabetes (9/30,30%) obesity (7/30, 23%) and chronic renal disease (5/30, 16,7%). Twenty (66,7%) patients presented overweight. Five patients (16,7%) had a Charlson comorbidity (Quan et al., 2011) score ≥3. Twenty-seven (90%) patients were virologically suppressed.CD4 count was >500cell/mm 3 in 23/30 (76,6%) patients. An antiviral treatment for SARS-COV2 was administered, in addition to HIV treatment, in 5/30 patients (16,3%). Twenty-four patients (80%) recovered from covid-19, 3/30 (10%) required invasive mechanical ventilation, 2/30 (6,7%) patients died and 4/30 (13,3%) patients were still hospitalized.

Most of the patients were virologically suppressed with CD4>500 mm3. Risk factors were the same as those described in other SARS-COV2 series, suggesting that HIV infection is probably not an independent risk factor for covid-19.

Pythium insidiosum causes a life-threatening condition called pythiosis. High morbidity and mortality of pythiosis are consequences of delayed diagnosis. We aimed to develop a loop-mediated isothermal amplification (LAMP) assay for the rapid detection of P. Entinostat insidiosum for use in remote areas, where pythiosis is prevalent.

We designed four LAMP primers to amplify the rDNA sequence. A side-by-side comparison evaluated performances of LAMP and the previously-established multiplex PCR (M-PCR), using gDNA samples extracted from colonies of P. insidiosum (n = 28) and other fungi (n = 54), and tissues of animals with (n = 16) or without (n = 13) pythiosis.

LAMP demonstrated a 50% shorter assay duration (1.5 h) and a 10-fold lower limit of detection (10
ng) than did M-PCR. Based on colony-extracted gDNAs, LAMP and M-PCR correctly reported P. insidiosum in all 28 samples, providing 100% sensitivity. While M-PCR did not amplify all fungal controls (100% specificity), LAMP falsely detected one organism (98% specificity). Based on the clinical samples, LAMP and M-PCR provided an equivalently-high specificity (100%). However, LAMP showed a markedly-higher sensitivity than that of M-PCR (88% vs. 56%).

LAMP is a simple, useful, efficient assay for the detection of P. insidiosum in clinical specimens and pure cultures in resource-limited laboratories.

Diagnosis of childhood TB still remains challenging when using conventional tests, due to the non-specific clinical manifestations and paucibacillary nature of the specimens. Thus, a sensitive, rapid and low-cost diagnostic test is of great demand. Benefiting from specific and rapid Cas-protein-based catalytic activities, CRISPR-based biosensing platforms (CRISPR platforms) are showing superiority in detecting pathogen nucleic acid traces in clinical samples. Based on their excellent sensitivity, and time and cost saved in existing research, this study aimed to highlight the potential of CRISPR platforms as a tool for diagnosing pediatric TB, and advocate for studies to evaluate its performance in specimens collected from children, especially noninvasive specimens. These platforms are also promising in identifying drug resistance and genotyping. All of the above will help early diagnosis of pediatric TB, thus guide reasonable treatment, and be significant in achieving the World Health Organization End-TB strategy.
