The present review provides the reader with the state-of-the-art concepts of sinonasal oncology in view of the latest literature data.

Most recent publications in sinonasal oncology assessed treatment timing, centralization, surgical approach, margin status, orbit/neck management, salvage strategies, emerging surgical technologies, intensity-modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), particle radiotherapy, and neoadjuvant chemotherapy.

Indications to endoscopic surgery for sinonasal cancer have plateaued and are unlikely to further expand. Endoscopic surgery provides noninferior results compared to open surgery and best suits timing constraints imposed by multimodal treatment. Management of orbit-encroaching sinonasal cancer is remarkably improving mostly owing to optimal use of nonsurgical strategies. Prognostic value of the margin status and management of the nodal basin and recurrent sinonasal tumors are far from being fully elucidated. Most promising surgical technos are far from being fully elucidated. Most promising surgical technologies are surgical navigation, optical imaging, and radiofrequency-aided ablation. IMRT and VMAT have theoretical technical advantages that are in the process of being clinically demonstrated. Pieces of evidence are progressively confirming the physical and radiobiological advantages offered by particle radiotherapy. Systemic therapy is being tested mostly in the neoadjuvant setting with the aim of improving outcomes in locally advanced sinonasal cancers; response to induction chemotherapy could better select a further locoregional approach.
Zidovudine (ZDV) has been extensively used in pregnant women to prevent vertical transmission of human immunodeficiency virus (HIV), but few studies have evaluated potential mutagenic effects of ZDV during fetal development.

Our study investigated clonal hematopoiesis in HIV-exposed uninfected (HEU) newborns, 94 of whom were ZDV-exposed and 91 antiretroviral therapy (ART)-unexposed and matched for potential confounding factors.

Utilizing high depth sequencing and genotyping arrays, we comprehensively examined blood samples collected during the first week after birth for potential clonal hematopoiesis (CH) associated with fetal ZDV exposure, including clonal single nucleotide variants (SNVs), small insertions and deletions (indels), and large structural copy number or copy neutral alterations.

We observed no statistically significant difference in the number of SNVs and indels per person in ZDV exposed children (adjusted ratio (95% confidence interval) for expected number of mutations=0.79 [0.50, 1.22], P = 0.3), and no difference in the number of large structural alterations. Mutations in common CH driver genes were not found in the study population. Mutational signature analyses on SNVs detected no novel signatures unique to the ZDV-exposed children and the mutational profiles were similar between the two groups.

Our results suggest that CH at levels detectable in our study is not strongly influenced by in utero ZDV exposure; however, additional follow-up studies are needed to further evaluate the safety and potential long-term impacts of in utero ZDV exposure in HEU children as well as better investigate genomic aberrations occurring late in pregnancy.

Passive immunization with broadly neutralizing antibodies (bNAbs) is under evaluation for HIV prevention. BNAbs target gp120 or gp41, two HIV envelope antigens commonly present in diagnostic tests. Depending on bNAb type and dose administered to humans, serum levels can reach ∼1 mg/mL and wane over several weeks to months. We investigated the reactivity of bNAbs in HIV serological tests to inform diagnostic testing practices for persons treated with these products.

The anti-gp120 bNAbs VRCO1, PGT121, PGT145, 3BNC117, 10-1074, and N6 and anti-gp41 bNAbs 10E8 and 10E8v4 were tested with the laboratory-based Bio-Rad Ag/Ab Combo assay, the point-of-care single-use Determine Combo, OraQuick, Reveal G4, SureCheck, Uni-Gold, INSTI and DPP HIV 1/2 assays, and the supplemental Geenius and HIV-1 Western blot assays.

At 1 mg/mL, all bNAbs were nonreactive in four screening tests. OraQuick, SureCheck, Reveal G4, and INSTI detected at least two bNAbs each; SureCheck exhibited reactivity to six bNAbs. Geenius was HIVred bNAbs.
Fat quality and quantity may affect health similarly or differently. Fat quality can be assessed by measuring fat density on CT scan (greater density = smaller, higher quality adipocytes). We assessed the effects of tesamorelin, a growth hormone-releasing hormone analogue that reduces visceral fat (VAT) quantity in some people living with HIV (PWH), on fat density.

Participants from two completed, placebo-controlled, randomized trials of tesamorelin for central adiposity treatment in PWH were included if they had either a clinical response to tesamorelin (VAT decrease ≥8%, ≈70% of participants) or were placebo-treated.

CT VAT and subcutaneous fat (SAT) density (Hounsfield Units, HU) were measured by a central blinded reader.

Participants (193 responders, 148 placebo) were 87% male and 83% white. Baseline characteristics were similar across arms, including VAT (-91 HU both arms, P = 0.80) and SAT density (-94 HU tesamorelin, -95 HU placebo, P = 0.29). Over 26 weeks, mean (SD) VAT and SAT density increased in tesamorelin-treated participants only [VAT +6.2 (8.7) HU tesamorelin, +0.3 (4.2) HU placebo, P < 0.0001; SAT +4.0 (8.7) HU tesamorelin, +0.3 (4.8) HU placebo, P < 0.0001]. The tesamorelin effects persisted after controlling for baseline VAT or SAT HU and area, and VAT [+2.3 HU, 95% confidence interval (4.5-7.3), P = 0.001) or SAT (+3.5 HU, 95% confidence interval (2.3-4.7), P < 0.001] area change.

In PWH with central adiposity who experienced VAT quantity reductions on tesamorelin, VAT and SAT density increased independent of changes in fat quantity, suggesting that tesamorelin also improves VAT and SAT quality in this group.

There are an estimated 38 million people with HIV (PWH), with significant economic consequences. We aimed to collate global lifetime costs for managing HIV.

We conducted a systematic review (PROSPERO CRD42020184490) using five databases from 1999 to 2019.

Studies were included if they reported primary data on lifetime costs for PWH. Epigenetic inhibitor Two reviewers independently assessed the titles and abstracts, and data were extracted from full texts lifetime cost, year of currency, country of currency, discount rate, time horizon, perspective, method used to estimate cost and cost items included. Descriptive statistics were used to summarize the discounted lifetime costs [2019 United States dollars (USD)].

Of the 505 studies found, 260 full texts were examined and 75 included. Fifty (67%) studies were from high-income, 22 (29%) from middle-income and three (4%) from low-income countries. Of the 65 studies, which reported study perspective, 45 (69%) were healthcare provider and the remainder were societal. The median lifetime costs for managing HIV differed according to country income level $5221 [interquartile range (IQR)] 2978-11 177) for low-income to $377 820 (IQR 260 176-541 430) for high-income; study perspective $189 230 (IQR 14 794-424 069) for healthcare provider, to $508 804 (IQR 174 781-812 418) for societal; and decision model $190 255 (IQR 13 588-429 772) for Markov cohort, to $283 905 (IQR 10 558-453 779) for microsimulation models.

Estimating the lifetime costs of managing HIV is useful for budgetary planning and to ensure HIV management is affordable for all. Furthermore, HIV prevention strategies need to be strengthened to avert these high costs of managing HIV.

In this proof-of-concept study, we used optical coherence tomography angiography (OCTA) to evaluate the retina as a convenient assessment of microvascular health among persons with HIV (PWH) undergoing surveillance ophthalmic care at Emory from 2018 to 2021. Among patients with longstanding HIV, OCTA identified microvascular abnormalities even among eyes without clinical retinal disease. Retinovascular evaluation by OCTA is a feasible, noninvasive technique for assessing microvasculopathy among PWH.
The aim of this study was to examine the role of ghrelin, obestatin and glutamate and their receptors in the pathogenesis of children functional constipation.

Children aged 4-17 were the subject of the study 121 children with constipation (55 boys and 66 girls), 36 patients at the same age (26 boys and 10 girls) were the controls. Expression of ghrelin, obestatin and glutamate receptors on gastric and colon specimens taken by endoscopy were assessed. The concentration of above agents was estimated in serum by ELISA test.

The lower median serum concentrations of ghrelin, in the constipated children than in controls were confirmed (1.9ng/ml vs. 2.6ng/ml, p < 0.05). The expression of metabotropic receptor for glutamate (mGlu7) RNA was higher in stomach (32.49 vs. 31.47, p < 0.05), and was lower in rectum in constipated patients compared to the control group (31.76 vs. 32.62, p < 0.05). Negative correlation between concentration of ghrelin in serum and colonic transient time (p = 0.01, rho = -0.23) was shown in study group.Higher median expression of obestatin receptor GPR39 in rectal mucosae was found in constipated group than in the controls (29.9 vs. 26.9, p < 0.05).

Ghrelin, and receptors for ghrelin, obestatin and glutamate in gastrointestinal mucosa play a role in the pathogenesis of functional constipation in children.

Compliance with manufacturer-recommended setup requirements for both primary and secondary infusions and secondary medication administration delay was compared between a head-height differential system and a cassette system. A total of 301 medication administration observations were included in this study 102 (34%) for the linear peristaltic IV smart pump (medical-surgical N = 51; critical care N = 51) and 199 (66%) for the cassette pump (medical-surgical N = 88; critical care N = 111). Results found a 0% compliance for primary line setup and 84% compliance for secondary line setup and 1 omitted medication due to a closed clamp with the linear peristaltic system. For the cassette system, there are no head-height requirements. Two roller clamps were found to be in the closed position on initiation of the secondary infusion, but the clinician was alerted by an alarm, so no medication delays occurred.
