The drug resistance of Plasmodium vivax in clinical cases remains largely unknown till date because of the difficulty in diagnosing the resistant P. vivax strains. The present study was undertaken to determine the prevalence of mutant alleles in drug resistance genes viz P. vivax multi-drug resistance (pvmdr-1), chloroquine resistance transporter (pvcrt-o), dihydrofolate reductase (pvdhfr) and dihydropteroate synthase (pvdhps) along with in vitro chloroquine (CQ) sensitivity in P. vivax clinical isolates. ZD4522 calcium During August-October 2017 a total of 86 samples of the febrile patients were screened and 31 samples were found to be positive for P. vivax in Safdarjung hospital, New Delhi. Sequence genotyping of the drug resistance genes was carried out in these P. vivax samples and in vitro CQ susceptibility for 23 isolates was determined by the schizont maturation assay (SMA). The CQ inhibitory concentrations (IC50) for the clinical isolates was found to be in the range of 25.6-176.7 nM. All the 31 clinical isolates analyzed for pvmdr-1 gene, showed mutant alleles and in only two isolates novel mutations at 861 and 898 codons were observed. Sequence analysis of pvcrt-o, pvdhfr and pvdhps genes revealed wild type genotypes in all the 31 studied isolates. The presence of mutations in pvmdr-1 gene and the increase in the CQ IC50 value indicates the possibility of shift in drug tolerance where CQ with primaquine (PQ) is still the first line of treatment for P. vivax malaria in the country. The regular molecular surveillance in P. vivax would provide useful information for the policy makers of the malaria control programme.
The purpose of this study was to evaluate the prognostic value of single-photon emission computed tomography (SPECT)/computed tomography (CT) imaging of angiosome foot perfusion for predicting amputation outcomes in patients with critical limb ischemia (CLI) and diabetes mellitus (DM).

Radiotracer imaging can assess microvascular foot perfusion and identify regional perfusion abnormalities in patients with critical limb ischemia CLI and DM, but the relationship between perfusion response to revascularization and subsequent clinical outcomes has not been evaluated.

Patients with CLI, DM, and nonhealing foot ulcers (n=25) were prospectively enrolled for SPECT/CT perfusion imaging of the feet before and after revascularization. CT images were used to segment angiosomes (i.e., 3-dimensional vascular territories) of the foot. Relative changes in radiotracer uptake after revascularization were evaluated within the ulcerated angiosome. Incidence of amputation was assessed at 3 and 12months after revascularizat-Based Perfusion Imaging of Patients With Peripheral Arterial Disease; NCT03622359).
Total hip arthroplasty (THA) is the most effective treatment option for patients with symptomatic osteoarthritis after a prior femoroacetabular osteoplasty (FAO). This study evaluated clinical outcomes of THA after a prior FAO and compared the results with a matched group of patients who underwent THA with no prior surgical procedures in the affected hip.

By reviewing our prospectively maintained database, we identified 74 hips (69 patients) that underwent THA after previous FAO between 2004 and 2017. They were matched 13 to a control group of primary THA with no history of any procedures on the same hip based on age, sex, body mass index, date of surgery, Charlson comorbidity index, surgical approach, and acetabular and femoral component type. At minimum 2-year follow-up, modified Harris Hip Score, 90-day readmission, and revision THA for any reason were compared between the groups.

The median time interval between FAO and subsequent THA was 1.64 years. There was no significant difference in preoperative Harris Hip Score between patients in the case and control cohorts. At the latest follow-up, the median modified Harris Hip Score was 77.6 in the case group and 96.2 in the control, and the difference was not statistically significant. None of the patients in the case group developed infection. 7 patients in the case group required additional procedures at any point, compared with 15 in the control.

THA after prior FAO has similar outcomes to primary THA in patients with no prior procedures in the affected hip. THA can be performed safely with excellent outcome in patients with a history of FAO.

Their use is intended as personal protection to prevent infection and as source control to limit transmission of the virus in a community or healthcare setting. Yet the wearing of masks has become a catalyst for political conflict, an arena where scientific evidence is often viewed through a partisan lens. The way that anti-maskers chafe at the mask requirement evokes a time when people were advised to wear a mask during the 1918 pandemic. As the Spanish flu swept through the world causing global devastation in 1918 and 1919, face masks became ubiquitous to help in preventing the spread of disease. A century apart, medical authorities urged and urge the wearing of masks to help slow the spread of disease. Nonetheless, people were and remain resistant to this simple and common sense advice. The purpose of this article is twofold to provide a brief literature review on the unequivocal scientific evidence that masks reduce community transmission in view of the current pandemic, review mask use in children and to compare and contrast attitudes to mask wearing during the Spanish flu and the COVID-19 pandemic, and analyse where these attitudes stem from.Fluorofenidone (AKF-PD) is a novel pyridone agent that reduces the deposition of extracellular matrix (ECM) in various models of renal fibrosis. However, there are no reports on the effect of AKF-PD in preventing fibrosis in the folic acid nephropathy model. Besides, the mechanisms of action of AKF-PD in preventing renal fibrosis are not fully understood. In the study, we observed that AKF-PD reduced folate-induced kidney injury, ameliorated the deterioration of renal function, and suppressed the deposition of ECM by decreasing the expression of collagen I, collagen III, transforming growth factor-β (TGF-β), fibronectin (FN), and alpha smooth muscle actin (α-SMA) in the folic acid nephropathy model. Additionally, AKF-PD suppressed the activation of the NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome to reduce the production of caspase-1 and IL-1β, and alleviated mitochondrial oxidative damage by promoting mitochondrial energy metabolism and reducing the expression of NADPH oxidase 4 (NOX4).
