There are about 2.1 million children infected with HIV globally and about 120 thousand deaths annually. Nigeria has one of the highest rates of paediatric HIV infection globally. Pre-treatment HIV drug resistance data inform the choice of first- and second-line antiretroviral therapy (ART) regimens. This study investigated the prevalence of HIV drug resistant strains among ART naïve children in Ibadan, Nigeria.<br /><br /> A total of 20 children aged less than 15 years were enrolled. Demographic, clinical and laboratory data were documented. Total nucleic acid was extracted from blood samples after which amplification of HIV-1 pol gene was done using polymerase chain reaction. Amplified gene was sequenced using big dye sequencing method. The sequenced HIV-1 pol gene was typed and analysed for identification of mutations indicative of drug resistance across the different classes of antiretroviral therapy.<br /><br /> HIV 1 RNA pol gene was successfully amplified in 12/20 (60%) children. All were identified as HIV1 and the subtypes were G and CRF 02AG, recombinant of 02_AG/G and recombinant of 02_AG/A1. Drug resistant mutations (DRM) were identified in 4/12 (33%). Three out of the four mutations were identified as Non-nucleoside reverse transcriptase inhibitors (NNRTI) DRM (K103N) while the fourth had nucleoside reverse transcriptase inhibitors (NRTI) DRM (M184V).<br /><br /> Results from this preliminary study show that drug resistance among ART-naïve children is a problem in Ibadan. Pre-treatment drug resistance testing is desirable in children prior to initiation of ART to guide effective treatment.<br /><br />Results from this preliminary study show that drug resistance among ART-naïve children is a problem in Ibadan.

With the aging of the population, ischemia-reperfusion injury is becoming a serious problem in various organs, such as the kidney, brain, and heart, as well as in the mesenteric capillaries. Recent Advances To prevent reperfusion injuries, natural and synthetic low-molecular-weight antioxidants have been well studied.<br /><br /> However, these low-molecular-weight antioxidants have various problems, including adverse effects due to excessive cellular uptake and their rapid clearance by the kidney, and cannot fully exert their potent antioxidant capacity in vivo.<br /><br /> To overcome these problems, we designed and developed redox polymers with antioxidants covalently conjugated with them. These polymers self-assemble into nanoparticles in aqueoux nanoparticles (RNPs). RNPs suppress their uptake into normal cells, accumulate at inﬂammation sites, and effectively scavenge reactive oxygen species in damaged tissues. We had developed two types of RNPs RNPN, which disintegrates in response to acidic pH; and RNPO, which does not collapse, regardless of the environmental pH. Utilizing the pH-sensitive and -insensitive characteristics of RNPN and RNPO, respectively, RNPs were found to exhibit remarkable therapeutic effects on various oxidative stress disorders, including ischemia-reperfusion injuries. Thus, RNPs are promising nanomedicines for use as next-generation antioxidants. This review summarizes the therapeutic impacts of RNPs in the treatment of kidney, cerebral, myocardial, and intestinal ischemia-reperfusion injuries.Background Magnet wireless charging is being utilized increasingly in current generation smartphones. Apple's MagSafe is a proprietary wireless charging technology with an array of magnets that has the capacity to generate magnet fieldstrength &gt;50 gauss (G). We hypothesize that there is clinically significant magnet interference caused by Apple's MagSafe technology on cardiac implantable electronic devices (CIED). Methods and Results This study has an in vivo and an ex vivo component. The in vivo component consists of consecutive patients who presented to the electrophysiology laboratory with previously implanted CIEDs. The iPhone 12 Pro Max was directly placed on the skin over the pocket of these patients and the effect was studied by device interrogation. For the ex vivo component of the study, CIEDs from major device companies were tested for magnetic interference caused by iPhone 12 Pro Max through unopened packages. [https://www.selleckchem.com/products/vbit-12.html Selleckchem VBIT-12] We found that iPhone 12 Pro Max resulted in clinically identifiable magnet interference in 3/3 (100%) participants in vivo and in 8/11 (72.7%) devices ex vivo. Conclusions Apple's iPhone 12 Pro Max MagSafe technology can cause magnet interference on CIEDs and has the potential to inhibit lifesaving therapy.<br /><br /> Patients with chronic ureteric obstruction (CUO) are traditionally managed with polymer stents/nephrostomy. However, these are prone to failure and require regular exchange. This study evaluates efficacy of Allium® URS, Memokath™-051 and Resonance® metallic ureteric stents in managing patients with CUO.<br /><br /> Following institutional approval, operating theatre records were reviewed to identify patients with CUO managed with either Allium® URS, Memokath™-051 or Resonance® metallic ureteric stents (September 2015/July 2020). Baseline patient variables (age, gender, underlying aetiology, ASA) and stricture characteristics (length, level, continuity) were extracted. Intra- and post-operative clinical and radiological assessments at 6 weeks, 3 months and then every 6 months, as well as any emergency attendances, were reviewed. The primary outcome was duration of functional stent survival. Secondary outcomes included intra-operative placement success and, as anestimate of renal function, mean serum creatinine over titive large-scale comparisons with long-term follow-up are needed to help inform stent choice dependant on individual patient and stricture characteristics.<br /><br />Allium® URS, Memokath™-051 and Resonance® metallic ureteric stents are all viable management options of CUO. In this cohort, Resonance® provided superior functional stent survival. Prospective large-scale comparisons with long-term follow-up are needed to help inform stent choice dependant on individual patient and stricture characteristics.
