Development and initial evaluation of a lateral flow dipstick test for antigen detection of Entamoeba histolytica in stool sample

Abstract Entamoeba histolytica infection remains a public health concern in developing countries. Early diagnosis of amoebiasis can avoid disease complications, thus this study was aimed at developing a test that can rapidly detect the parasite antigens in stool samples. Rabbits were individually immunized with recombinant pyruvate phosphate dikinase (rPPDK) and E. histolytica excretory-secretory antigens to produce polyclonal antibodies. A rapid dipstick test was produced using anti-rPPDK PAb lined on the dipstick as capture reagent and anti-EhESA PAb conjugated to colloidal gold as the detector reagent. Using E. histolytica-spiked in stool sample of a healthy individual, the detection limit of the dipstick test was found to be 1000 cells ml−1. Meanwhile when rPPDK was spiked in the stool sample, the minimum concentration detected by the dipstick test was 0.1 μg ml−1. The performances of the dipstick, commercial Techlab E. histolytica II enzyme-linked immunosorbent assays (ELISA) and real-time PCR were compared using 70 stool samples from patients infected with Entamoeba species (n = 45) and other intestinal pathogens (n = 25). When compared to real-time PCR, the diagnostic sensitivity of the dipstick for detection of E. histolytica was 65.4% (n = 17/26); while the diagnostic specificity when tested with stool samples containing other intestinal pathogens was 92% (23/25). In contrast, Techlab E. histolytica II ELISA detected 19.2% (5/26) of the E. histolytica-positive samples as compared to real-time PCR. The lateral flow dipstick test produced in this study enabled rapid detection of E. histolytica, thus it showed good potential to be further developed into a diagnostic tool for intestinal amoebiasis.
The prevalence and concordance of human papillomavirus infection in different anogenital sites among men and women in Liuzhou, China: A population‐based study

Human papillomavirus (HPV) infection is the pathogenesis of anogenital cancers and genital warts in both men and women, whereas there is a scarcity of large studies focused on HPV prevalence in different anogenital sites of both sexes in the same population. From May to July 2014, 2,309 men and 2,378 women aged 18–55 were enrolled from communities in Liuzhou, China. Penis/glans penis/coronary sulcus (PGC) and perianal/anal canal (PA) specimens of men, and vaginal (VA), vulvar (VU) and PA specimens of women, were collected and genotyped for HPV. The prevalence of any HPV tested in PGC and PA samples from men and VA, VU and PA samples from women was 10.8%, 3.8%, 14.2%, 13.3% and 8.4%, respectively. The concordance of VA and VU was highest (kappa = 0.74), followed by VU and PA (0.44), VA and PA (0.38) and PGC and PA (0.14). Besides sex behavior, ever having used a towel supplied by a hotel was a risk factor for both external genital and PA HPV infection. Our data indicated that women were more of a major reservoir for oncogenic HPV infection of both genital sites and PA sites than was men. In both sexes, the genital sites were more likely than PA sites to harbor HPV infection. The concordance rates of HPV infection between genital sites and PA infection were poor.
Development of loop-mediated isothermal amplification with Plasmodium falciparum unique genes for molecular diagnosis of human malaria

Abstract In order to achieve better outcomes for treatment and in the prophylaxis of malaria, it is imperative to develop a sensitive, specific, and accurate assay for early diagnosis of Plasmodium falciparum infection, which is the major cause of malaria. In this study, we aimed to develop a loop-mediated isothermal amplification (LAMP) assay with P. falciparum unique genes for sensitive, specific, and accurate detection of P. falciparum infection. The unique genes of P. falciparum were randomly selected from PlasmoDB. The LAMP primers of the unique genes were designed using PrimerExplorer V4. LAMP assays with primers from unique genes of P. falciparum and conserved 18S rRNA gene were developed and their sensitivity was assessed. The specificity of the most sensitive LAMP assay was further examined using genomic DNA from Plasmodium vivax, Plasmodium yoelii and Toxoplasma gondii. Finally, the unique gene-based LAMP assay was validated using clinical samples of P. falciparum infection cases. A total of 31 sets of top-scored LAMP primers from nine unique genes were selected from the pools of designed primers. The LAMP assay with PF3D7_1253300-5 was the most sensitive with the detection limit 5 parasites/μl, and it displayed negative LAMP assay with the genomic DNA samples of P. vivax, P. yoelii, and T. gondii. The LAMP assay with PF3D7_0112300 (18S rRNA) was less sensitive with the detection limit 50 parasites/μl, and it displayed negative LAMP assay with the genomic DNA samples of P. yoelii and T. gondii, but displayed positive LAMP detection with P. vivax. The positive detection rate of the LAMP assay with PF3D7_1253300-5 was 90% (27/30), higher than that (80%, 24/30) of the positive rate of PF3D7_0112300 (18S rRNA) in examining clinical samples of P. falciparum infection cases. The LAMP assay with the primer set PF3D7_1253300-5 was more sensitive, specific, and accurate than those with PF3D7_0112300 (18S rRNA) in examining P. falciparum infection, and therefore it is a promising tool for diagnosis of P. falciparum infection.
Ovarian cancer early detection by circulating CA125 in the context of anti‐CA125 autoantibody levels: Results from the EPIC cohort

CA125 is the best ovarian cancer early detection marker to date; however, sensitivity is limited and complementary markers are required to improve discrimination between ovarian cancer cases and non‐cases. Anti‐CA125 autoantibodies are observed in circulation. Our objective was to evaluate whether these antibodies (1) can serve as early detection markers, providing evidence of an immune response to a developing tumor, and (2) modify the discriminatory capacity of CA125 by either masking CA125 levels (resulting in lower discrimination) or acting synergistically to improve discrimination between cases and non‐cases. We investigated these objectives using a nested case–control study within the European Prospective Investigation into Cancer and Nutrition cohort (EPIC) including 250 cases diagnosed within 4 years of blood collection and up to four matched controls. Circulating CA125 antigen and antibody levels were quantified using an electrochemiluminescence assay. Adjusted areas under the curve (aAUCs) by 2‐year lag‐time intervals were calculated using conditional logistic regression calibrated toward the absolute risk estimates from a pre‐existing epidemiological risk model as an offset‐variable. Anti‐CA125 levels alone did not discriminate cases from controls. For cases diagnosed <2 years after blood collection, discrimination by CA125 antigen was suggestively higher with higher anti‐CA125 levels (aAUC, highest antibody tertile: 0.84 [0.76–0.92]; lowest tertile: 0.76 [0.67–0.86]; phet = 0.06). We provide the first evidence of potentially synergistic discrimination effects of CA125 and anti‐CA125 antibodies in ovarian early detection. If these findings are replicated, evaluating CA125 in the context of its antibody may improve ovarian cancer early detection.
Data Sharing and the Idea of Ownership

Ideas about ownership are sometimes used in discussions of data sharing in personalised medicine. Personal health data are thought by many to be ‘theirs’. Paradoxically, personalised medicine (at least in the context of genomics) relies on the aggregation of private data into a dataset that is held as a form of knowledge commons. When the notions of private and common property that lie behind this discourse are made explicit we can use thinking about the justifications and jurisprudence of property both to clarify the persuasiveness and limits of such claims, and also how they differ from other principles that are at stake in the interplay between individual and collective goods in the delivery of personalised medicine. This shows that ownership might more plausibly lie with health professionals than patients. In a socialised medicine system, such as the NHS, such professionals are agents of the state and ownership would lie with the commons rather than any individual. Common rather than private ownership of genomic information may be more appropriate.
A novel pathway activated by somatostatin receptor type 2 (SST2): Inhibition of pituitary tumor cell migration and invasion through cytoskeleton protein recruitment

The pharmacological therapy of GH‐secreting pituitary tumors is based on somatostatin (SS) analogs that reduce GH secretion and cell proliferation by binding mainly SS receptors type 2 (SST2). Antimigratory effects of SS have been demonstrated in different cell models, but no data on pituitary tumors are available. Aims of our study were to evaluate SST2 effects on migration and invasion of human and rat tumoral somatotrophs, and to elucidate the molecular mechanism involved focusing on the role of cofilin and filamin A (FLNA). Our data revealed that SST2 agonist BIM23120 significantly reduced GH3 cells migration (−22% ± 3.6%, p < 0.001) and invasion on collagen IV (−31.3% ± 12.2%, p < 0.01), both these effects being reproduced by octreotide and pasireotide. Similar results were obtained in primary cultured cells from human GH‐secreting tumors. These inhibitory actions were accompanied by a marked increase in RhoA/ROCK‐dependent cofilin phosphorylation (about 2.7‐fold in GH3 and 2.1‐fold in human primary cells). Accordingly, the anti‐invasive effect of the SS analog was mimicked by the overexpression in GH3 cells of the S3D phosphomimetic cofilin mutant, and abolished by both phosphodeficient S3A cofilin and a specific ROCK inhibitor that prevented cofilin phosphorylation. Moreover, FLNA silencing and FLNA dominant‐negative mutants FLNA19‐20 and FLNA21‐24 transfection demonstrated that FLNA plays a scaffold function for SST2‐mediated cofilin phosphorylation. Accordingly, cofilin recruitment to agonist‐activated SST2 was completely lost in FLNA silenced cells. In conclusion, we demonstrated that SST2 inhibits rat and human tumoral somatotrophs migration and invasion through a molecular mechanism that involves FLNA‐dependent cofilin recruitment and phosphorylation.
Assessment of Patient Health Literacy: A National Survey of Plastic Surgeons

Background: Health literacy affects patient participation, compliance, and outcomes. Nearly half of American adults have inadequate functional health literacy. Identification and accommodation of patients with low literacy is an important goal of the American Medical Association, U.S. Department of Health and Human Services, and the Healthy People 2020 initiative. This study aims to assess plastic surgeons’ perception of patient literacy. Methods: A survey was distributed to American Society of Plastic Surgeons members about time devoted to patient counseling, use of techniques for evaluating and enhancing patient understanding, perception of level of education, and estimated literacy. Participation was voluntary and data were collected anonymously using an online survey tool. Results: There were 235 participants in the survey (9.9 percent response rate). Patient literacy was most frequently assessed using their general impression (62.2 percent) and by asking patients about their employment (37.3 percent); 26.2 percent did not assess literacy. The majority of surgeons (62 percent) reported spending at least 20 minutes counseling new patients, and 37 percent reported spending more than 30 minutes. Lay terminology (94 percent) and pictures/diagrams (84.6 percent) were common patient education aids, whereas only 8.1 percent use teach-back methods. Plastic surgeons overestimated the level of education and reading level of their patients compared with national data. Conclusions: Formal assessment of health literacy is rarely performed, as most plastic surgeons use a general impression. Although plastic surgeons devote significant time to patient counseling, evidence-based communication methods, such as the teach-back method, are underused. Simple, directed questions can identify patients with low literacy skills, to accommodate their communication needs.
RhoA‐stimulated intra‐capillary morphology switch facilitates the arrest of individual circulating tumor cells

Metastasis is the primary cause of death for most cancer patients. Hematogenous arrest of circulating tumor cells (CTCs) is an essential prerequisite for metastases formation. Using transparent transgenic zebrafish (kdrl:eGFP; Casper), together with resonant laser scanning confocal microscopy, we tracked the fate of CTCs in vivo in the blood circulation for days. We found the intra‐capillary morphology‐switch (ICMS) of individual CTCs from strip to sphere was necessary for their intravascular arrests. Further genetic and pharmacological inhibition experiments indicated that the RhoA signaling was necessary for ICMS and the arrest of CTCs. At last, we demonstrated that early treatment by a clinically approved RhoA/ROCK inhibitor, Fasudil, could efficiently inhibit the initial arrest of individual CTCs and reduce the incidence of tumor metastasis in both zebrafish and mouse models. These results together indicate that RhoA‐stimulated ICMS represents a mechanism for the arrest of individual CTCs, providing a potential target for future treatments of hematogenous metastatic disease.
Alcohol consumption and risk of hematological malignancies: A meta‐analysis of prospective studies

Current convincing evidence suggests that alcohol intake increases the risk of several carcinomas, which might subsequently lead to a recommendation toward limiting alcohol consumption. However, there are accumulating data worth meta‐analyzing that show a different effect on the risk of hematological malignancies. Eligible cohort studies were sought in PubMed database up to August 31, 2016. Separate analyses were performed by subtype of hematological malignancy (non‐Hodgkin lymphoma [NHL] and subtypes, Hodgkin lymphoma [HL], leukemia and subtypes), time status (ever, current, former), level of consumption (light, moderate, heavy), alcoholic beverage (total alcohol, beer, liquor, wine) and gender. Moderate and heavy alcohol consumption were significantly associated with reduced risk of NHL (relative risk [RR] = 0.85, 95% confidence interval [CI]: 0.80–0.90 and RR = 0.73, 95%CI: 0.60–0.89, respectively); a protective trend was also shown for light alcohol intake (RR = 0.93, 95%CI: 0.87–1.00). Specifically, beer consumption was associated with reduced NHL risk (RR = 0.88, 95%CI: 0.81–0.95). However, the association regarding other alcoholic beverages seemed null. The beneficial effects of alcohol mainly pertained to Diffuse Large B‐Cell Lymphoma (DLBCL) (RR = 0.83, 95%CI: 0.77–0.89) and Follicular Lymphoma (FL) (RR = 0.85, 95%CI: 0.78–0.93). There was also no association between alcohol consumption and risk of HL or leukemias. In contrast to most solid malignancies, alcohol seems to confer a protective effect on NHL risk, especially on DLBCL and FL subtypes, with beer being notably beneficial.
FACE-Q Scales for Health-Related Quality of Life, Early Life Impact, Satisfaction with Outcomes, and Decision to Have Treatment: Development and Validation

Background: An ever-growing range of facial cosmetic products and treatments are available, but little clinical research is being performed to determine treatment outcomes from the patient’s perspective. The FACE-Q is a patient-reported outcome instrument composed of more than 40 independently functioning scales and checklists. The aim of this article is to describe the development and psychometric evaluation of five new FACE-Q scales. Methods: FACE-Q scales were developed according to international guidelines for patient-reported outcome instrument development. The following FACE-Q scales and a single symptom checklist (Recovery Early Symptoms) were evaluated in this study: Psychological Wellbeing, Social Function, Satisfaction with Decision to Have Treatment, Satisfaction with Outcome of Treatment, and Early Life Impact of Treatment. Modern and traditional psychometric methods were used to examine reliability, validity, and responsiveness. Results: The sample included 702 participants from three studies. The FACE-Q scales were found to be reliable, valid, and responsive to clinical change. These findings were supported by Rasch measurement theory (e.g., overall chi-square values, p ≥ 0.06; Person Separation Index ≥0.81), traditional psychometric (e.g., Cronbach alpha values ≥0.90) and responsiveness (i.e., significant improvement following face lift and lip treatment) analysis. Conclusions: The FACE-Q measures concepts and symptoms important to facial aesthetic patients. The five scales and single symptom checklist described here can be used to measure what patients think about cosmetic treatments in a scientifically sound manner. As the cosmetics industry continues to expand, the patient perspective of treatment outcomes should be measured and reported. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, III.
Macroeconomic factors and share returns: an analysis using emerging market data

This paper investigates the extent to which global and local economic factors explain returns in emerging stock markets (ESMs). The economic factors are determined using principal components analysis. The results suggest that the local economic variables included in this study can be summarized by GDP, inflation, money and interest rates, while the selected global variables can be sufficiently characterized by world industrial production and world inflation. These components are then used as inputs into a regression analysis in order to explain the index returns of 13 ESMs over the period 1987-96. The analysis indicates that while world factors are significant in explaining ESM returns, local factors may also play a crucial role. Copyright @ 2002 by John Wiley & Sons, Ltd. All rights reserved.
The Search for the Ideal Thin Skin Flap: Superficial Circumflex Iliac Artery Perforator Flap—A Review of 210 Cases

Background: The superficial circumflex iliac artery perforator flap is a thin skin flap that can be harvested reliably and quickly from the groin. It is ideal for single-stage resurfacing of cutaneous defects. The donor site heals well and is easily concealed. The authors clarify the anatomy, simplify the flap harvest technique, and outline the modifications to expand the applications of this flap. Methods: Between January of 2011 and January of 2014, 210 superficial circumflex iliac artery perforator flaps were performed at Asan Medical Center. The flaps were used for head and neck reconstruction (n = 13), upper extremity reconstruction (n = 19), lower limb reconstruction (n = 176), and reconstruction in the trunk region (n = 2). All flaps were raised suprafascially using a free-style approach. The anatomy of the flap, the elevation technique, and the results of the reconstruction were assessed. Results: The average flap size was 86 cm2, ranging from 17.5 to 216 cm2 (mean vertical width, 6.3 cm; mean transverse length, 13.5 cm). Total flap loss occurred in 10 flaps (4.8 percent). Two patients developed complications at the donor site. Debulking surgery was performed in five patients (2.4 percent). The average follow-up period was 400 days (range, 30 to 1690 days). Conclusions: The superficial circumflex iliac artery perforator flap enables accurate resurfacing of moderate-size cutaneous defects. It is vascularly robust and versatile for use in different sites. This is the thinnest skin flap presently available and has the potential to become the new workhorse flap for resurfacing moderate-size skin defects. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
Lifestyle Changes and Blood Pressure Control: A Community‐Based Cross‐Sectional Survey (2006 Ontario Survey on the Prevalence and Control of Hypertension)

To evaluate lifestyle changes and their impact on hypertension control in a sample of hypertensive respondents in Ontario, Canada, diet, physical activity, and other nonpharmacologic measures were recorded using a structured questionnaire during the 2006 Ontario Survey on the Prevalence and Control of Hypertension. Responses were weighted to the total adult population of 7,996,653 in Ontario. The prevalence of hypertension was 21%; 42% of hypertensive persons received therapy with antihypertensive drugs and lifestyle changes, and 41% received therapy with drugs only. Blood pressure was controlled in 85% of respondents who used only drugs and in 78% of those who stated that they received therapy with combined drug treatment and lifestyle changes. Fewer than half of hypertensive respondents practiced lifestyle changes (in combination with drug treatment) for blood pressure control. Lifestyle measures in addition to medication use did not result in better control of hypertension compared to only medication use.
Food intake and dosage level, but not tablet vs solution dosage form, affect the absorption of metformin HC1 in man

The pharmacokinetics of four single-dose treatments of the metformin administered orally (as the HCl salt) were compared in 24 healthy subjects: 500 mg and 850 mg tablets and 850 mg solution fasting and 850 mg tablet with food. Solution and tablet formulations are bioequivalent. Bioavailability of a 500 mg tablet is 14% greater than that of an 850 mg tablet. Compared with the fasting state, bioavailability is 24% lower, and the peak concentration delayed about 37 min when an 850 mg tablet is administered with food.
Determinants for the Effectiveness of Lifestyle Intervention in the Finnish Diabetes Prevention Study

In our recent publication (1), we showed that among participants in the Finnish Diabetes Prevention Study, a diabetes prevention trial using lifestyle intervention, those who had the highest baseline composite diabetes risk as measured by the Finnish Diabetes Risk Score (FINDRISC) achieved the largest risk reduction during the lifestyle intervention. We appreciate the comment written by Schulze. However, the major part of the comment addresses our earlier publication (3) describing the development and validation of the risk prediction model using two large, population-based cohorts. In that paper, we extensively discussed the issues raised by …
SQM1 Antiody defines a surface membrane antigen in squamous carcinoma of the head and neck

We produced murine monoclonal antibodies (MAbs) directed against the surface membrane of squamous‐cell carcinoma of the head and neck (SCCHN). One antibody, SQMI, was determined by immunofluorescence and radioimmunoassay to be reactive with 13/13 SCCHN cell lines derived from different sites of the head and neck area. No binding reaction was observed with normal fibroblasts, red blood cells, nucleated bone‐marrow cells or epithelial cells from normal oral mucosa. SQMI reactivity was observed with primary cultures of normal epidermal and bronchial epithelial cells. Significant reactivity was found with 2/4 cell lines derived from small‐cell carcinoma of the lung but little or no reactivity was found with other lung cancer cell lines. Various cell lines derived from other cancers including breast, colon, and ovarian carcinomas, melanoma, neuroblastoma and leukemia were generally unreactive. Seventeen out of 18 fresh frozen specimens of SCCHN were strongly reactive with SQMI antibody. However, autopsy specimens from the heart, liver, kidney, spleen, colon, subcutaneous fat and skin connective tissue were unreactive. SQMI antibody may be useful in biological and clinical studies of the head and neck region.
