Nasofacial conidiobolomycosis.

A case of Nasofacial Zygomycosis in a 15-year-old male patient from South India is reported. This patient had typical thickening of the nasofacial mucosa and the skin overlying it. The diagnosis was confirmed with fungal cultures. Although initially good response to treatment with potassium iodide was achieved, later the response was unsatisfactory, probably partly due to irregularity in treatment. Treatment with sulphamethoxazole--trimethoprim and prednisolone combination has resulted in remarkable improvement.     

Pharmacy practice research priorities during the COVID-19 pandemic: Recommendations of a panel of experts convened by FIP Pharmacy Practice Research Special Interest Group

Across the globe, pharmacists on the frontline continue to fight COVID-19 and its continuously evolving physical, mental, and economic consequences armed by their knowledge, professionalism, and dedication. Their need for credible scientific evidence to inform their practice has never been more urgent. Despite the exponentially increasing number of publications since the start of the pandemic, questions remain unanswered, and more are created, than have been resolved by the increasing number of publications.A panel of leading journal editors was convened by the International Pharmaceutical Federation (FIP) Pharmacy Practice Research Special Interest Group to discuss the current status of COVID-19 related research, provide their recommendations, and identify focal points for pharmacy practice, social pharmacy, and education research moving forward.Key priorities identified spanned a wide range of topics, reflecting the need for good quality research to inform practice and education. The panel insisted that a foundation in theory and use of rigorous methods should continue forming the basis of inquiry and its resultant papers, regardless of topic area. From assessing the clinical and cost effectiveness of COVID-19 therapies and vaccines to assessing different models of pharmaceutical services and education delivery, these priorities will ensure that our practice is informed by the best quality scientific evidence at this very challenging time.

Water treatment and handwashing behaviors among non-pregnant friends and relatives of participants in an antenatal hygiene promotion program in Malawi

Access to safe drinking water and improved hygiene are essential for preventing diarrheal diseases. To integrate hygiene improvement with antenatal care, free hygiene kits (water storage containers, water treatment solution, soap) and educational messages were distributed to pregnant women at antenatal clinics in Malawi. We assessed water treatment and hygiene practices of 275 non-pregnant friends and relatives of the hygiene kit recipients at baseline and follow-up nine months later to measure program impact on non-participants in the same communities. At follow-up, friends and relatives who did not receive kits or education were more likely than at baseline to purchase and use water treatment solution (25% versus 1%; P < 0.0001) and demonstrate correct handwashing practices (60% versus 18%; P < 0.0001). This antenatal clinic-based program resulted in improved water treatment and hygiene behaviors among non-pregnant friends and relatives living in the same communities as hygiene kit recipients, suggesting that program benefits extended beyond direct beneficiaries.     

A Prospective Study in Comparison of Ambulatory Phlebectomy and Duplex Guided Foam Sclerotherapy in the Management of Varicosities with Isolated Perforator Incompetence

Perforators are those which connect the superficial and deep venous system either directly to main veins or indirectly through the muscular and soleal venous plexus. The emergence of minimally invasive techniques like ambulatory phlebectomy (AP) and foam sclerotherapy (FS) has led to increasing interest about the appropriate therapy for the treatment of isolated perforator incompetence. There have been no studies which have compared the effectiveness of these in-office procedures in isolated perforator incompetence due to the low prevalence of cases. The primary goal of this study is to compare the clinical parameters (return to normal activity, primary symptom relief), functional parameters (procedure time, change in disease severity, course of venous ulcer), and duplex parameters (recurrence in treated veins, complete occlusion of treated veins) in the management of leg varicosities having isolated primary perforator incompetence by ambulatory phlebectomy and duplex guided foam sclerotherapy. Though the procedure time was shorter with FS than AP, the other parameters of primary symptom relief such as change in disease severity, faster healing of venous ulcer, complete occlusion of treated veins in follow-up duplex examination, and lower recurrence of treated veins are better with AP than FS. In conclusion, the interruption of perforators is effective in decreasing the symptoms of chronic venous insufficiency and for the rapid healing of ulcers. The interruption of the incompetent perforating veins appears to be essential to decrease ambulatory venous hypertension. It is apparent from this study that ambulatory phlebectomy stands distinct with enormous benefits and serves as a superior alternative to foam sclerotherapy in treating patients with isolated perforator incompetence.     

A Formal Mentorship Program for Faculty Development

Objective. To describe the development, implementation, and evaluation of a formal mentorship program at a college of pharmacy.Methods. After extensive review of the mentorship literature within the health sciences, a formal mentorship program was developed between 2006 and 2008 to support and facilitate faculty development. The voluntary program was implemented after mentors received training, and mentors and protégés were matched and received an orientation. Evaluation consisted of conducting annual surveys and focus groups with mentors and protégés.Results. Fifty-one mentor-protégé pairs were formed from 2009 to 2012. A large majority of the mentors (82.8%-96.9%) were satisfied with the mentorship program and its procedures. The majority of the protégés (≥70%) were satisfied with the mentorship program, mentor-protégé relationship, and program logistics. Both mentors and protégés reported that the protégés most needed guidance on time management, prioritization, and work-life balance. While there were no significant improvements in the proteges’ number of grant submissions, retention rates, or success in promotion/tenure, the total number of peer-reviewed publications by junior faculty members was significantly higher after program implementation (mean of 7 per year vs 21 per year, p=0.03) in the college’s pharmacy practice and administration department.Conclusions. A formal mentorship program was successful as measured by self-reported assessments of mentors and protégés.     

Predicted expression of genes involved in the thiopurine metabolic pathway and azathioprine discontinuation due to myelotoxicity

TPMT and NUDT15 variants explain less than 25% of azathioprine‐associated myelotoxicity. There are 25 additional genes in the thiopurine pathway that could also contribute to azathioprine myelotoxicity. We hypothesized that among TPMT and NUDT15 normal metabolizers, a score combining the genetically predicted expression of other proteins in the thiopurine pathway would be associated with a higher risk for azathioprine discontinuation due to myelotoxicity. We conducted a retrospective cohort study of new users of azathioprine who were normal TPMT and NUDT15 metabolizers. In 1201 White patients receiving azathioprine for an inflammatory disease, we used relaxed Least Absolute Shrinkage and Selection Operator (LASSO) regression to select genes that built a score for discontinuing azathioprine due to myelotoxicity. The score incorporated the predicted expression of AOX1 and NME1. Patients in the highest score tertile had a higher risk of discontinuing azathioprine compared to those in the lowest tertile (hazard ratio [HR] = 2.15, 95% confidence interval [CI] = 1.11–4.19, p = 0.024). Results remained significant after adjusting for a propensity score, including sex, tertile of calendar year at initial dose, initial dose, age at baseline, indication, prior TPMT testing, and the first 10 principal components of the genetic data (HR = 2.11, 95% CI = 1.08–4.13, p = 0.030). We validated the results in a cohort (N = 517 non‐White patients and those receiving azathioprine to prevent transplant rejection) that included all other patients receiving azathioprine (HR = 2.00, (95% CI = 1.09–3.65, p = 0.024). In conclusion, among patients who were TPMT and NUDT15 normal metabolizers, a score combining the predicted expression of AOX1 and NME1 was associated with an increased risk for discontinuing azathioprine due to myelotoxicity.

Study Highlights

• WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC?

Azathioprine is an immunosuppressant that causes myelotoxicity in some people. Clinical Pharmacogenetics Implementation Consortium (CPIC) guidelines provide azathioprine dosing recommendations based on TPMT and NUDT15 genotype; however, these genotypes explain only 25% of azathioprine‐induced myelotoxicity.

• WHAT QUESTION DID THIS STUDY ADDRESS?

The aim of this study was to determine if a risk score composed of the genetically predicted expression of genes that encode proteins in the thiopurine pathway within the liver tissue would be associated with azathioprine discontinuation attributed to myelotoxicity.

• WHAT DOES THIS STUDY ADD TO OUR KNOWLEDGE?

This study showed that a risk score composed of genetically predicted risk expression of AOX1 and NME1 is associated with azathioprine discontinuation due to myelotoxicity.

• HOW MIGHT THIS CHANGE CLINICAL PHARMACOLOGY OR TRANSLATIONAL SCIENCE?

Having a risk score for discontinuation composed of the genetically predicted expression of NME1 and AOX1 could help discriminate patients at high risk of discontinuing azathioprine due to hematologic side effects in people who are normal TPMT and NUDT15 metabolizers.     

Production of agglutinators and rheumatoid factors in plasma cells of rheumatoid and nonrheumatoid synovial tissues

Immunohistochemical studies were performed in synovial tissues from 40 patients with rheumatoid arthritis (RA), 9 with juvenile rheumatoid arthritis (JRA), 7 with psoriatic arthritis, and 4 with various rheumatic diseases. Overall synthesis of IgG– and/or IgM–rheumatoid factor (RF) was found in all patients with seropositive RA and JRA, in 75% of patients with seronegative RA, and in 1 patient with psoriatic arthritis. Agglutinator producing cells were found in 77% of the samples from seropositive RA and in 44% and 56% from seronegative RA and JRA patients, respectively. The percentage of IgG plasma cells synthesizing one or more of the 5 types of agglutinators studied was approximately 10% of plasma cells synthesizing IgG–RF. Intercellular and intracellular immune complex deposits were also found in patients with seropositive and seronegative RA and JRA. These findings suggest that synthesis of agglutinators by synovial tissue plasma cells of RA and JRA patients is a distinct—but definitely less prominent—function than that of RF synthesis.     

Serum protein profile studies of cervical cancers in monitoring of tumor response to radiotherapy using HPLC-LIF: A pilot study

ObjectiveExploration of the feasibility of serum protein profiles for monitoring tumor radioresponse in cervical cancers using HPLC-LIF system.Materials and methodsTwenty-one subjects were recruited in the study. Out of them 7 were healthy, 14 were cervical cancer patients who undertook fractionated radiotherapy (RT) with 2 Gy per fraction over 25 fractions, for 5 weeks followed by 2 applications of intracavitary brachytherapy once a week.Blood collected from above subjects was processed to obtain serum. Serum chromatograms of ‘normal’ (n=7) and conspicuous probes before RT (n=14, ‘malignant’) and 24 h after second fraction of RT (n=13, ‘2-RT’), were recorded using an In-house-built HPLC-LIF set-up. Data were analyzed in two approaches: (1) classical method using relative intensities of selected peaks, (2) principal component analysis (PCA).Clinical assessment of tumor radioresponse was carried out 4 months after first fraction of RT and the degree of the tumor shrinkage was determined as an index of radioresponsiveness (complete response (CR): 100% shrinkage, partial response (PR): ≥50% shrinkage, and no response (NR): ≤50% shrinkage) which was further correlated with the analysis of 2-RT serum chromatograms.ResultsNormal vs. malignant chromatograms demonstrated pronounced differences in the 800–1800 s region. Malignant vs. 2-RT chromatograms showed minute variations in the 1300–1800 s region. Our analysis, in both of the approaches, produced clear differentiation between ‘normal’ and ‘malignant’, whereas differentiation between ‘malignant’ and ‘2-RT’ was minimal. Clinical evaluation of the tumor radioresponse yielded that out of 13 patients (one patient discontinued the radiotherapy) ten showed CR, two showed PR and one NR. In case of prediction of tumor radioresponse, analysis of the 2-RT chromatograms produced only minor differentiation among CR, PR and NR groups.ConclusionProtein profiling of serum samples differentiated ‘normal’ from ‘malignant’, but could not differentiate ‘malignant’ from ‘2-RT’. Also this technique has limited application in prediction of tumor radioresponse.
