Sub-Saharan Africa remains the epicentre of the HIV pandemic, yet enormous knowledge gaps still exist to elicit a comprehensive portrait of multimorbidity and HIV linkage. This study aims to conduct a systematic meta-analysis of peer-reviewed literature to investigate the current status of multimorbidity epidemiology among people living with HIV (PLHIV) in sub-Saharan Africa.

Our review will assess observational studies (ie, cohort, case-control and cross-sectional) on multimorbidity associated with HIV/AIDS between 1 January 2005 and 31 October 2020 from sub-Saharan Africa. Databases to be searched include PubMed/MEDLINE, Scopus, Web of Science, Cochrane library, African Index Medicus and African Journals Online. We will also search the WHO clinical trial registry and databases for systematic reviews. The search strategy will involve the use of medical subject headings and key terms to obtain studies on the phenomena of HIV and multimorbidity at high precision. Quality assessment of eligible studies will be ascertained using a validated quality assessment tool for observational studies and risk of bias through sensitivity analysis to identify publication bias. Further, data on characteristics of the study population, multimorbid conditions, epidemiological rates and spatial distribution of multimorbid conditions in PLHIV will be extracted. Heterogeneity of individual studies will be evaluated using the I
statistic from combined effect size estimates. The statistical analysis will be performed using STATA statistical software V.15 and results will be graphically represented on a forest plot.

Ethical approval is not applicable in this study as it is a systematic review of published literature. The review findings may also be presented at conferences or before other relevant stakeholders.

Cancer risk is higher in people living with HIV (PLWH) compared with the general population, and cancers related to age are expected to be most prevalent.

We determined the spectrum and incidence rates of AIDS-defining cancers (ADC) and non-AIDS-defining cancers (NADC) and of lung, Hodgkin lymphoma (HL), head and neck (HNC), colon-rectum, anal, liver, breast, prostate, and urinary bladder cancers between January 2010 and December 2015 in the French Dat'AIDS cohort. Incidence rates were calculated by year and compared using the

test for linear trend. Standardized incidence ratios [SIR (95% confidence interval)] were calculated relative to the French general population.

Among 44,642 patients, corresponding to 180,216.4 person-years (PY), 1,440 cancer cases occurred in 1,314 patients. ADC incidence was 191.4 (172.3-212.7)/10
PY and declined over time overall and in men, whereas NADC incidence was higher [548.8 (515.6-584.1)/10
PY] and did not change. In men, non-Hodgkin lymphoma was the most common cancer, but prostate cancer had the highest incidence among NADCs. Breast cancer was the most common cancer in women. SIRs were higher for cervical cancer [1.93 (1.18-3.14)], HNC in women [2.4 (1.4-4.2)], liver [overall 3.8 (3.1-4.6); men 3.2 (2.5-4.0); women 12.9 (8.3-20.0)], and HL [overall 13.8 (11.1-17.1); men 16.2 (12.9-20.4); women 6.2 (3.22-11.9)] but lower for lung [overall 0.7 (0.6-0.9); men 0.7 (0.5-0.8)], prostate [0.6 (0.5-0.7)], and breast cancers [0.6 (0.4-0.7)].

Spectrum of NADCs has changed, with prostate and breast cancers becoming the most common despite their lower SIR.

These results confirm the need to maintain regular epidemiologic cancer monitoring in order to update screening guidelines.

Here, we identified a major role for the globular (G)-actin-binding protein thymosin-β4 (TMSB4X) in PCP establishment and cell adhesion in the developing epidermis. Depletion of Tmsb4x in mouse embryos hindered eyelid closure and hair-follicle angling owing to PCP defects. Tmsb4x depletion did not preclude epidermal cell adhesion in vivo or in vitro; however, it resulted in abnormal structural organization and stability of adherens junction (AJ) due to defects in filamentous (F)-actin and G-actin distribution. In cultured keratinocytes, TMSB4X depletion increased the perijunctional G/F-actin ratio and decreased G-actin incorporation into junctional actin networks, but it did not change the overall actin expression level or cellular F-actin content. A pharmacological treatment that increased the G/F-actin ratio and decreased actin polymerization mimicked the effects of Tmsb4x depletion on both AJs and PCP. Our results provide insights into the regulation of the actin pool and its involvement in AJ function and PCP establishment.
Atypical lymphocytes circulating in blood have been reported in COVID-19 patients. This study aims to (1) analyse if patients with reactive lymphocytes (COVID-19 RL) show clinical or biological characteristics related to outcome; (2) develop an automatic system to recognise them in an objective way and (3) study their immunophenotype.

Clinical and laboratory findings in 36 COVID-19 patients were compared between those showing COVID-19 RL in blood (18) and those without (18). Clofarabine order Blood samples were analysed in Advia2120i and stained with May Grünwald-Giemsa. Digital images were acquired in CellaVisionDM96. Convolutional neural networks (CNNs) were used to accurately recognise COVID-19 RL. Immunophenotypic study was performed throughflow cytometry.

Neutrophils, D-dimer, procalcitonin, glomerular filtration rate and total protein values were higher in patients without COVID-19 RL (p<0.05) and four of these patients died. Haemoglobin and lymphocyte counts were higher (p<0.02) and no patients died in the gesence suggests an abundant production of virus-specific T cells, thus explaining the better outcome of patients showing these cells circulating in blood.
The outcome of deploying balloon-mounted stents for symptomatic intracranial atherosclerotic stenosis (ICAS) has not been fully investigated. In this study we evaluate the safety and long-term outcome of using balloon-mounted stents to treat symptomatic ICAS in comparison with the WEAVE/WOVEN study.

In a multicenter registry study of stenting for symptomatic intracranial artery stenosis in China, 159 patients treated with an intracranial balloon-mounted stent approved by the China Food and Drug Administration were evaluated. The morphological features of the lesions were categorized by Mori classification. The endpoints, including periprocedural and long-term clinical and radiological outcomes, were the same as those in the WEAVE/WOVEN study.

In the present study the mean percent stenosis before and after stenting was 84.0% and 6.1%, respectively. The proportions of Mori A, Mori B, and Mori C lesions were 33.3%, 52.2%, and 14.5%, respectively. The 72-hour rates of stroke and mortality after the procedure were 0%. The 1-year rates of any stroke, ischemic stroke, hemorrhagic stroke, and death were 6.3% (10/159), 5.7% (9/159), 0.6% (1/159), and 0.6% (1/159), respectively. The 1-year rate of in-stent restenosis (ISR) was 23.4% (15/64). The rate of ISR in Mori C lesions (53.8%, 7/13) was significantly higher than that in Mori A (15.8%, 3/19) or Mori B lesions (15.6%, 5/32) (p=0.024).

The short-term and long-term outcomes of using a balloon-mounted stent for symptomatic ICAS with focal and non-angular lesions (Mori A and B type) and smooth arterial access were comparable to the results of the WEAVE/WOVEN trial.

Providing end-of-life care has a significant psychological impact on critical care nurses. Little is known about whether critical care nurses find death rounds useful as a support system. This study aimed to describe critical care nurses' perceptions of attending death rounds.

This study was conducted using a qualitative descriptive design, using one-to-one audio-recorded interviews. The study was conducted at a 20-bed medical intensive care unit in a 1200-bed public tertiary hospital in Singapore. One-to-one interviews were conducted with 14 nurses using a semi-structured interview guide. Data was analysed using thematic analysis.

Critical care nurses valued attending death rounds. They found death rounds to be an outlet to express themselves and remember patients, to draw and give peer support, to build nursing and interprofessional cohesiveness and to learn to improve palliative care. The death rounds were optimal when they felt safe to share, when there was a good facilitator, when the hierarchy was flat and when the audience was interdisciplinary. The barriers to a successful death round were the rounds being too formal, timing and not knowing the patients.

Death rounds are a viable way to support critical care nurses in providing end-of-life care.

SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) receptors to infect and damage ciliated epithelial cells in the upper respiratory tract. In alveoli, gas exchange occurs across an epithelial-endothelial barrier that ties respiration to endothelial cell (EC) regulation of edema, coagulation, and inflammation. How SARS-CoV-2 dysregulates vascular functions to cause ARDS in COVID-19 patients remains an enigma focused on dysregulated EC responses. Whether SARS-CoV-2 directly or indirectly affects functions of the endothelium remains to be resolved and is critical to understanding SARS-CoV-2 pathogenesis and therapeutic targets. We demonstrate that primary human ECs lack ACE2 receptors at protein and RNA levels and that SARS-CoV-2 is incapable of directly infecting ECs derived from pulmonary, cardiac, brain, umbilical vein, or kidffuse alveolar damage and systemic coagulopathy, thrombosis, and capillary inflammation that tie alveolar responses to EC dysfunction. This has prompted theories that SARS-CoV-2 directly infects ECs through ACE2 receptors, yet SARS-CoV-2 antigen has not been colocalized with ECs and prior studies indicate that ACE2 colocalizes with alveolar epithelial cells and vascular smooth muscle cells, not ECs. Here, we demonstrate that primary human ECs derived from lung, kidney, heart, brain, and umbilical veins require expression of recombinant ACE2 receptors in order to be infected by SARS-CoV-2. However, SARS-CoV-2 lytically infects ACE2-ECs and elicits procoagulative and inflammatory responses observed in COVID-19 patients. These findings suggest a novel mechanism of COVID-19 pathogenesis resulting from indirect EC activation, or infection of a small subset of ECs by an ACE2-independent mechanism, that transforms rationales and targets for therapeutic intervention.
